Risk factors for developing cardiac and vascular diseases include:

Age (over 50 years)

Race (African-American)

History of smoking

Diabetes

High blood pressure

High blood cholesterol

Personal history of vascular disease, heart attack, or stroke.

We believe medical personnel and insurance plans who deliver care for individuals over the age of 50 represent the target market for QuantaFlo. Based on U.S. Census data, we believe there are more than 80 million older Americans who could be evaluated for the presence of cardiac and vascular diseases.

There are over 400,000 medical professionals practicing primary care in the United States. In addition, based on American Heart Association data, there are over 30,000 cardiologists and 7,000 vascular and cardiovascular surgeons. Also, there are millions of diabetic patients seen routinely by endocrinologists. Many podiatrists who see patients with these problems and orthopedic surgeons may see value in screening patients for circulation issues prior to leg procedures. Neurologists may need a tool to differentiate leg pain from vascular versus neurologic etiology. Nephrologists see patients with kidney disease, who have a higher frequency of cardiac and vascular diseases. Wound care centers need to know the adequacy of limb perfusion. We expect that each physician will have many patient visits annually from people older than 50 years. While it is standard practice to ask about symptoms of cardiac and vascular diseases and to look for signs on physical exam, we believe that it is often the case in busy practices that the questions go unasked.

Other Products and Services

In addition to our internal research and development efforts, from time to time, we may make investments in, or distribute products from other companies that we believe are complementary to QuantaFlo. For example, we previously made an investment in Mellitus Health, Inc, or Mellitus, and had an exclusive agreement to market and distribute its product, Insulin Insights. Due to slow uptake of the product despite our marketing efforts, we wrote off our prepaid licenses and a portion of our investment as of December 31, 2023.

In October 2020, we invested in SYNAPS , whose product, Discern, is a test for early Alzheimer’s disease. In December 2022, we purchased a senior secured convertible promissory note of Monarch Medical Technologies, LLC, or Monarch, (as amended in December 2024 and January 2025), maker of EndoTool, a technology-enabled approach to inpatient glycemic management. We do not have a distribution agreement for Discern or EndoTool.

We continue to evaluate other investment and distribution opportunities for other products and services, and recently entered into distribution arrangements for other products that we believe would be of interest to our customers given the patient populations they serve, as we seek to complement our existing product offering.

Strategy

Our mission is to develop, manufacture and market products and services that assist healthcare providers in evaluating and treating chronic diseases. We intend to do this by:

Targeting customers with patients at risk of developing PAD and other cardiovascular diseases (subject to FDA clearance). Healthcare providers use blood flow measurements as part of their assessment of a patient’s cardiac and vascular condition. Our strategy is to keep marketing QuantaFlo on a recurrent revenue model to insurance plans and medical personnel who care for those older than 50 years, including cardiologists, internists, nephrologists, endocrinologist, podiatrists, and family practitioners. Specifically, we believe there are more than 400,000 physicians and other potential customers in the United States alone, many of whom care for patients older than 50 years old and at increased risk of developing PAD and other cardiovascular diseases. Based on U.S. Census data, the evaluable patient population for QuantaFlo is estimated to be more than 80 million patients in the United States annually.

Expanding the tools available to internists and non-peripheral vascular experts. Our intention is to provide a tool to internists and non-cardiovascular experts, for whom it was previously impractical to conduct a blood flow measurement unless in a specialized vascular laboratory. For cardiovascular specialists, QuantaFlo does not require the use of blood pressure cuffs (which should not be used on some breast cancer patients), and measures without blood pressure in obese patients and patients with non-compressible, hard, calcified arteries. Currently, these patients often are unable to be measured satisfactorily with traditional devices.

Developing additional product and service offerings that allow healthcare providers to deliver cost-effective wellness and receive increased compensation for their services. In March 2015, we received FDA 510(k) clearance of our product, QuantaFlo, to aid clinicians in the diagnosis and monitoring of PAD. The cleared device reflected several updates and modifications to the original model that were developed in conjunction with our consultant engineering groups. We are seeking a new 510(k) clearance for the expanded use of QuantaFlo following correspondence with the FDA. The new 510(k) is intended to enable expanded labeling for QuantaFlo as an aid in the diagnosis of other cardiovascular diseases in addition to PAD. Further, we continue to explore potential new product and service offerings through our research and development programs. Our goal is to provide cost-effective wellness solutions for our growing, established customer base, achieve a reputation for outstanding service, all while leveraging our gains in the marketplace for such product and service offerings.

Exploring additional product and service offerings through arrangements. In addition to our in-house research and development efforts, we are also seeking out opportunities to expand our product and service offerings through marketing, distribution and licensing arrangements. Such arrangements will allow us to sell products related to chronic disease management through our network of physicians and other customers.

Sales and Marketing

We provide our QuantaFlo product and any other products for which we have distribution rights to our customers through our salespersons, who have experience selling products and services to our anticipated market.

We deliver QuantaFlo directly to our customers, and in-service training to the customers is provided either on-line or in person. Because QuantaFlo is relatively easy to use, training can generally be accomplished in less than one day. We are currently test marketing the other products we distribute, products in the cardiovascular care space that we believe are attractive to our current customer base. We do not currently have any material revenues from these initial test marketing efforts, which will inform our sales and marketing strategy.

Customers who have licensed our QuantaFlo product may pay by credit card or check generally on the 15 th of each month as an advance for usage during the next 30 days. In some cases, customers prefer an annual or quarterly license paid in advance. We provide technical support daily, coupled directly to the manufacturing operation so that replacement products, if needed, can be shipped overnight directly to the customer. The majority of the support is over the telephone

Table of Contents

and focuses on software and connectivity issues, rather than hardware. We upgrade QuantaFlo operating systems as appropriate by direct shipments or electronically.

In addition to the license model with a fixed monthly fee, we also have contracts that charge a variable monthly fee, in which we invoice based on the number of tests performed with QuantaFlo. In addition to licensing the QuantaFlo software, we have sold QuantaFlo equipment and accessories.

Manufacturing

We manufacture our product, QuantaFlo, in the United States through independent contractors whom we pay for finished goods. Our contracts provide for subassemblies, product final assembly, test, serialization, finished goods, inventory and shipping operations. Our current contracts will remain in force until terminated by us upon three months written notice, or until terminated by either party for cause. Although we believe we have a good working relationship with our current contract manufacturers, there are many such qualified contract manufacturers available around the country should we need to replace them or if they are not able to meet demand as we grow our business as anticipated. While our current independent contract manufacturers source some supplies from China, we believe QuantaFlo is relatively easy to manufacture, and should we encounter issues due to supply chain disruptions as a result of the recent tariff proposals of the current U.S. administration, or a global health emergency, such as the COVID-19 pandemic or any other global supply chain constraints, we believe alternative sources should be available. We employ a consultant vendor qualification expert to monitor and test the quality controls and quality assurance procedures of our contract manufacturer.

Competition

The principal competitor for QuantaFlo is the standard blood pressure cuff ABI device. QuantaFlo does not include a blood pressure cuff. There are several companies that manufacture the traditional ABI device, which range in price from $2,500 to $20,000. Some of these companies are much larger than us and have more financial resources and their own distributor network. The traditional ABI devices are differentiated by the degree of automation designed into each product. ABI devices that rely more heavily on operator assessment ( i.e. , listening to the return of pulse while decreasing cuff pressure), are thought to have less objectivity in their measurement. Because standard ABI devices require a better trained operator, the products are usually sold to specialized vascular labs that are supervised by a vascular surgeon, with the tests performed by a licensed vascular technician. It is not uncommon for such ABI devices to be marketed to the offices of internists, podiatrists, endocrinologists or most cardiologists.

Our intention is to provide a tool to internists and non-cardiovascular experts, for whom it was previously impractical to conduct a blood flow measurement unless in a specialized vascular laboratory. For cardiovascular specialists, QuantaFlo does not require the use of blood pressure cuffs (which should not be used on some breast cancer patients), and measures without blood pressure in obese patients and patients with non-compressible, hard, calcified arteries. Currently, these patients often are unable to be measured with traditional devices.

Competitors are marketing competing digital devices seeking to provide fast results that may be used outside of a specialized vascular laboratory. Given the potential size of the market, we expect competitors to continue to enter the space.

Research and Development Program

We have dedicated engineering consultants that are well integrated into our overall business, ranging from customer requirements to technical support. The engineering group uses our in-house quality system as its framework for new product development and release. The majority of the engineering is circuit design and software development. We are currently developing several updates and modifications to QuantaFlo in conjunction with our consultant engineering groups, as well as exploring potential new product and service offerings. These product and service offerings are being designed to provide cost-effective wellness solutions for our growing, established customer base. The new products and service offerings under development or that may be developed may incorporate some of our current technology or new technology. We are also directing much of our activity to building our trade secrets and protecting proprietary positions.

Clinical Experience

Several studies of our blood flow measurement products have been conducted by our customers or authors facilitated by access to our database. Other studies were conducted by our customers using their own independently generated datasets.

One of these studies, the results of which were compiled in 2012 and published in a peer reviewed journal in 2013, sought to determine the frequency of finding undiscovered vascular disease in primary care practices using our vascular testing product. In the study of 632 patients at 19 office practices, the frequency of flow obstruction was 12% and of these patients, 75% did not have classic symptoms of PAD. Among other limitations of the study, the publication mentioned the study’s retrospective design, no direct comparison to other vascular tests and passive data collection such that 8% of patients had one or more missing data fields.

Another study was designed to assess the side-by-side performance of our vascular testing product compared with traditional analog ABI with Doppler measurements in medical practices. In the study of 181 limbs from 121 patients at 5 medical practices during 2012 and 2013, three techniques were used on all limbs: our test, traditional analog ABI with Doppler, and Duplex ultrasound imaging as a gold standard. Traditional analog ABI with Doppler was unable to perform a conclusive study in 8.7% of limbs. In the remaining limbs, our vascular testing product and the ABI with Doppler measurements were in agreement, or in other words concordant, in 78% of limbs. Among the discordant limbs, Duplex imaging judged that the true positive rate of our vascular testing product was significantly higher than that of ABI with Doppler by a 2 to 1 margin. The results of the study are available as a white paper that may be shown to potential customers or other interested parties. Among other limitations of the study, the study had a small sample size, was conducted at specialty practices not primary care practices, had a retrospective design with incomplete collection of demographic information and clinical characteristics of the population, and was not peer reviewed.

Another study also was designed to assess the side-by-side performance of our vascular testing product compared with traditional analog ABI with Doppler measurements in medical practices. In this prospective study at five medical practices during 2013 through 2015, 360 limbs from 180 patients were examined with three techniques: Our vascular testing product, traditional analog ABI with Doppler, and Duplex ultrasound imaging as a gold standard. Results demonstrated that our test demonstrated greater sensitivity, greater accuracy and equivalent specificity compared to ABI with Doppler measurements. The results of the study are available as a white paper. Among limitations of the study are that it had a small sample size, was conducted at a mix of primary care and specialty practices, had no formal tracking of consecutive patients, and was not peer reviewed.

Another study, the results of which were compiled and published in a peer reviewed journal in 2018, reported an analysis of a registry of screening PAD testing with our product between January 2017 and July 2017. In this study, 226,565 patients were tested and 31.3% had moderate to severe flow impairment in the lower extremities. Further analysis of a subset of 26,459 patients for whom clinical characteristics were recorded showed that 95% were asymptomatic. The authors concluded that earlier recognition of PAD may lead to earlier secondary preventive measures and improved outcomes for a population with a high-risk of cardiovascular mortality and morbidity. Among other limitations of the study, the publication mentioned the study’s retrospective design and that clinical factors were recorded for only approximately 10% of patients.

A retrospective case series compiled and published in a peer reviewed journal in 2018 reported on 48 patients that were tested with our product and subsequently had a contrast angiography procedure for clinical indications. Using contrast angiography as the gold standard for determining PAD, the author concluded the data supports the use of our product as an aid for practicing physicians to accurately diagnose PAD in combination with clinical judgment. Among other limitations of the study, the sample size was small, tests were performed at specialty centers, and the analysis was done retrospectively.

Certain racial and economic groups in the United States are underserved by the medical community with limited access to specialists, a lack of early detection programs and inadequate preventive disease management. There is abundant evidence that certain ethnic populations are more at risk for cardiovascular disease and suffer sequelae of untreated PAD. A study was compiled and published in a peer reviewed journal in 2018 that presented a retrospective

Table of Contents

analysis of 1,901 patients tested with our product at 22 medical practices that serve predominately lower-income, non-white populations. The author concluded that our product can be effectively utilized by primary care clinicians in poor and underserved communities to identify PAD. The author posited that identifying PAD earlier in the disease process can be an important step towards filling the unmet need of higher intensity vascular care for minority populations. Limitations of the study include that it was a retrospective analysis and that there was no protocol to unveil the identity or ethnicity of any of the individual patients.

Women may lack early detection programs and have inadequate preventive disease management. A study was compiled and published in a peer reviewed journal in 2019 that presented a retrospective analysis of 68,402 female patients tested with our product at primary care medical practices in the United States. The author concluded that our product was an efficient means to aid in the diagnosis of PAD in vulnerable women who are currently underserved by their health care providers. Limitations of the study include that it was a retrospective analysis with self-reporting of clinical characteristics.

A February 2022 published peer-reviewed study analyzed point-of-care tests using QuantaFlo for asymptomatic patients in a Medicare Advantage population between January 2016 and December 2016. In this study, 13,971 patients were tested and 31.6% had a positive result for PAD. Almost 60% had lower socio-economic income level with 15.1% living under the poverty level. The risk associated with detecting PAD was substantial with a 60-70% increased risk of all-cause mortality or morbidity at one year and a 40-50% increased risk of all-cause mortality or morbidity at three years. The risk was not modified by a history of coronary or cerebrovascular artery disease. The authors concluded that these findings highlight an enormous potential to realize cost-savings by reducing cardiovascular event rates and deploying population-based PAD risk mitigation strategies. Among other limitations of the study, the publication mentioned that they were not able to study the potential impact of PAD risk management strategies used after a positive PAD screen was communicated with the primary care provider and patient. This may have led to an underestimation of the true risk as targeted PAD risk management and behavior modification strategies may have been initiated at the discretion of the provider and patient.

A September 2022 peer-reviewed study under real-world conditions, illustrating the benefits of PAD in-home screening was published. The study analyzed screening tests using QuantaFlo for Medicare Advantage beneficiaries aged ≥65 years participating in the Optum HouseCalls program in the United States between April 1, 2017 and February 1, 2019. Of the 192,500 patients tested in their homes, 27.7% had a positive result for PAD. One-year all-cause mortality, 1- and 2-year major adverse cardiovascular events or MACE, and major adverse limb events or MALE, in the PAD positive patients were all significantly increased versus those patients who screened negative for PAD (p <.001). Moreover, the severity of the test results was associated with worse outcomes. The authors stated, “Detecting previously undiagnosed peripheral artery disease is a way to risk stratify a population that would benefit from further cardiovascular risk management.” Among other limitations of the study, the publication mentioned that the findings are only generalizable to individuals aged ≥65 years and the study could not assess the proportion of deaths due to cardiovascular causes.

A February 2023 peer-reviewed study was published assessing the accuracy of our vascular testing product using cardiac echocardiography or Echo, as a gold standard of heart failure. Results were that our test showed a significant correlation with Echo (p<.01). Among other limitations of the study, the publication mentioned that data on severity were not including and outcomes following preventative measures were not studied.

Patents and Licenses

We have been issued one patent for our apparatus, U.S. Patent No. 7,628,760, which expires December 11, 2027.

Government Regulation

Bitcoin Regulation

The laws and regulations applicable to bitcoin and digital assets are evolving and subject to interpretation and change.

Table of Contents

Governments around the world have reacted differently to digital assets; certain governments have deemed them illegal, and others have allowed their use and trade without restriction, while in some jurisdictions, such as the United States, digital assets are subject to overlapping, uncertain and evolving regulatory requirements.

As digital assets have grown in both popularity and market size, the U.S. Executive Branch, Congress and a number of U.S. federal and state agencies, including the Financial Crimes Enforcement Network, the CFTC, the SEC, the Financial Industry Regulatory Authority, the Consumer Financial Protection Bureau, the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the IRS and state financial regulators, have been examining the operations of digital asset networks, digital asset users and digital asset exchanges, with particular focus on the extent to which digital assets can be used to violate state or federal laws, including to facilitate the laundering of proceeds of illegal activities or the funding of criminal or terrorist enterprises, and the safety and soundness and consumer-protective safeguards of exchanges or other service-providers that hold, transfer, trade or exchange digital assets for users. Many of these state and federal agencies have issued consumer advisories regarding the risks posed by digital assets to investors. In addition, federal and state agencies, and other countries have issued rules or guidance regarding the treatment of digital asset transactions and requirements for businesses engaged in activities related to digital assets.

Depending on the regulatory characterization of bitcoin, the markets for bitcoin in general, and our activities in particular, our business and our bitcoin acquisition strategy may be subject to regulation by one or more regulators in the United States and globally. Ongoing and future regulatory actions may alter, to a materially adverse extent, the nature of digital assets markets, the participation of industry participants, including service providers and financial institutions in these markets, and our ability to pursue our bitcoin strategy. Additionally, U.S. state and federal and foreign regulators and legislatures have taken action against industry participants, including digital assets businesses, and enacted restrictive regimes in response to adverse publicity arising from hacks, consumer harm, or criminal activity stemming from digital assets activity. U.S. federal and state energy regulatory authorities are also monitoring the total electricity consumption of cryptocurrency mining, and the potential impacts of cryptocurrency mining to the supply and dispatch functionality of the wholesale grid and retail distribution systems. Many state legislative bodies have passed, or are actively considering, legislation to address the impact of cryptocurrency mining in their respective states.

The CFTC takes the position that some digital assets, including bitcoin, fall within the definition of a “commodity” under the Commodities Exchange Act of 1936, as amended, or CEA. Under the CEA, the CFTC has broad enforcement authority to police market manipulation and fraud in spot digital assets markets in which we may transact. Beyond instances of fraud or manipulation, the CFTC generally does not oversee cash or spot market exchanges or transactions involving digital asset commodities that do not utilize margin, leverage, or financing. In addition, CFTC regulations and CFTC oversight and enforcement authority apply with respect to futures, swaps, other derivative products and certain retail leveraged commodity transactions involving digital asset commodities, including the markets on which these products trade.

The SEC and its staff have taken the position that certain other digital assets fall within the definition of a “security” under the U.S. federal securities laws. Public statements made by senior officials and senior members of the staff at the SEC indicate that the SEC does not consider bitcoin to be a security under the federal securities laws, and the approval of the spot bitcoin ETPs support this view. However, such statements are not official policy statements by the SEC and reflect only the speakers’ views, which are not binding on the SEC or any other agency or court and cannot be generalized to any other digital assets. In addition, in January 2025, the SEC acting Chairman announced a new Crypto Task Force dedicated to developing a comprehensive and clear regulatory framework for digital assets.

In addition, because transactions in bitcoin provide a degree of anonymity, they are susceptible to misuse for criminal activities, such as money laundering. This misuse, or the perception of such misuse, could lead to greater regulatory oversight of bitcoin and bitcoin platforms, and there is the possibility that law enforcement agencies could close bitcoin platforms or other bitcoin-related infrastructure with little or no notice and prevent users from accessing or retrieving bitcoin held via such platforms or infrastructure. For example, a January 2021 nomination hearing before the Senate Finance Committee, it was noted that cryptocurrencies have the potential to improve the efficiency of the financial system but that they can be used to finance terrorism, facilitate money laundering, and support activities that threaten U.S. national security interests and the integrity of the U.S. and international financial systems. The OFAC has

Table of Contents

issued updated advisories regarding the use of virtual currencies, added a number of digital asset exchanges and service providers to the Specially Designated Nationals and Blocked Persons list and engaged in several enforcement actions, including a series of enforcement actions that have either shut down or significantly curtailed the operations of several smaller digital asset exchanges associated with Russian and/or North Korean nationals.

Activities involving bitcoin and other digital assets may fall within the jurisdiction of more than one financial regulator and various courts and such laws and regulations are rapidly evolving and increasing in scope. On March 9, 2022, an executive order relating to cryptocurrencies was signed. While the executive order did not mandate the adoption of any specific regulations, it instructed various federal agencies to consider potential regulatory measures, including the evaluation of the creation of a U.S. CBDC. On September 16, 2022, the White House released a framework for digital asset development, based on reports from various government agencies, including the U.S. Department of Treasury, the Department of Justice, and the Department of Commerce. Among other things, the framework encourages regulators to pursue enforcement actions, issue guidance and rules to address current and emergent risks, support the development and use of innovative technologies by payment providers to increase access to instant payments, consider creating a federal framework to regulate nonbank payment providers, and evaluate whether to call upon Congress to amend the Bank Secrecy Act and laws against unlicensed money transmission to apply explicitly to digital asset service providers. There have also been several bills introduced in Congress that propose to establish additional regulation and oversight of the digital asset markets. With the recent change in the U.S. administration, there is uncertainty about future regulatory oversight and enforcement and what rules and regulations may ultimately govern. For example, in January 2025, an executive order was issued that revoked the prior administration's executive order and Treasury Department's framework, and established the Presidential Working Group on Digital Asset Markets that will be tasked with developing a federal regulatory framework governing digital assets.

product sales and distribution.

FDA’s Premarket Clearance and Approval Requirements

To commercially distribute QuantaFlo or any future medical device we develop requires or will require either prior 510(k) clearance or prior approval of a premarket approval, or PMA, application or de novo classification from the FDA. The FDA classifies medical devices into one of three classes. Devices deemed to pose lower risk are placed in either class I or II, which requires the manufacturer to submit to the FDA a premarket notification requesting permission for commercial distribution. This process is known as 510(k) clearance. Some low risk devices are exempt from this requirement. Class I devices are those for which safety and effectiveness can be reasonably assured by adherence to FDA’s “general controls”, which include compliance with the applicable portions of the FDA’s Quality System Regulation, or QSR, facility registration and product listing, reporting of adverse medical events and malfunctions through the submission of medical device reports, and appropriate, truthful and non-misleading labeling, advertising and promotional materials. Class II devices are subject to FDA’s general controls and any other “special controls” deemed necessary by FDA to ensure the safety and effectiveness of the device, such as performance standards, special labeling requirements, patient registries or post-market surveillance. Devices deemed by the FDA to pose the greatest risk, such as life-sustaining, life-supporting or implantable devices, or devices deemed not substantially equivalent to a previously cleared 510(k) device are placed in class III, requiring approval of a PMA application. To market low to moderate risk devices that are automatically placed into class III, a manufacturer may request a de novo classification from FDA. Premarket notifications, PMA applications and de novo classification requests are subject to the payment of user fees, paid at the time of submission for FDA review. The FDA can also impose restrictions on the sale, distribution or use of devices at the time of their clearance or approval or authorization, or subsequent to marketing.

510(k) Clearance Pathway

To obtain 510(k) clearance, a medical device manufacturer must submit a premarket notification demonstrating that the proposed device is substantially equivalent to a previously cleared 510(k) device or a device that was in commercial distribution before May 28, 1976 for which the FDA has not yet called for the submission of a PMA application or a device that has been reclassified from class III to class II or class I. A device is substantially equivalent if, with respect to the predicate device, it has the same intended use and has either (i) the same technological characteristics, or (ii) different technological characteristics, but the information provided in the 510(k) submission demonstrates that the device does not raise new questions of safety and effectiveness and is at least as safe and effective as the predicate device. The FDA’s 510(k) clearance pathway usually takes from three to 12 months from the date the notification is submitted, but it can take significantly longer, and clearance is never assured. Although many 510(k) premarket notifications are cleared without clinical data, in some cases, the FDA requires significant clinical data to support substantial equivalence. In reviewing premarket notification, the FDA may request additional information, including clinical data, which may significantly prolong the review process. After a device receives 510(k) clearance, any modification that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, will require a new 510(k) clearance or could require a PMA application or de novo request for classification. The FDA requires each manufacturer to make this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. If the FDA disagrees with a manufacturer’s determination regarding whether a new premarket submission is required for the modification of an existing device, the FDA can require the manufacturer to cease marketing and/or recall the modified device until clearance or approval is obtained.

Premarket Approval Pathway

A PMA application must be submitted if the device cannot be cleared through the 510(k) clearance process and requires proof of the safety and effectiveness of the device to the FDA’s satisfaction. Accordingly, a PMA application must be supported by extensive data including, but not limited to, technical information regarding device design and development, preclinical studies and clinical trials, data and manufacturing and labeling to support the FDA’s determination that the device is safe and effective for its intended use. After FDA determines that a PMA application is sufficiently complete to permit a substantive review, the FDA begins an in-depth review of the submitted information, which generally takes between one and three years, but may take significantly longer. During this review period, the

Table of Contents

FDA may request additional information or clarification of information already provided. Also, during the review period, an advisory panel of experts from outside the FDA may be convened to review and evaluate the application and provide recommendations to the FDA as to the approvability of the device. In addition, the FDA will conduct a preapproval inspection of the manufacturing facility to ensure compliance with the QSR, which impose elaborate design development, testing, control, documentation and other quality assurance procedures in the design and manufacturing process. The FDA may approve a PMA application with post-approval conditions intended to ensure the safety and effectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution and collection of long-term follow-up data from patients in the clinical study that supported approval. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including the loss or withdrawal of the approval. New PMA applications or PMA application supplements are required for significant modifications to the manufacturing process, labeling and design of a device that is approved through the PMA process. PMA supplements often require submission of the same type of information as a PMA application, except that the supplement is limited to information needed to support any changes from the device covered by the original PMA application, and may not require as extensive clinical data or the convening of an advisory panel.

De Novo Classification Pathway

Device types that the FDA has not previously classified as class I, II or III are automatically classified into class III regardless of the level of risk they pose. To market low to moderate risk devices that are automatically placed into class III due to the absence of a predicate device, a manufacturer may request a de novo classification. This procedure allows a manufacturer whose novel device is automatically classified into class III to request classification of its device into class I or II on the basis that the device presents low or moderate risk, rather than requiring the submission and approval of a PMA application. The FDA is required to classify the device within 120 days following receipt of the de novo classification request, although in practice, the FDA’s review may take significantly longer. If the manufacturer seeks reclassification into class II, the manufacturer must include a draft proposal for special controls that are necessary to provide a reasonable assurance of the safety and effectiveness of the device. The FDA may reject the de novo classification request if it identifies a legally marketed predicate device that would be appropriate for a 510(k) or determines that the device is not low to moderate risk or that general controls would be inadequate to control the risks and special controls cannot be developed. In the event FDA determines the data and information submitted demonstrate that general controls or general and special controls are adequate to provide reasonable assurance of safety and effectiveness, FDA will grant the de novo request for classification. When FDA grants a de novo request for classification, the device is granted marketing authorization and further can serve as a predicate for future devices of that type through a 510(k) premarket notification.

Clinical Trials

Clinical trials are typically required to support a PMA and often for a de novo classification request, and are sometimes required to support a 510(k) submission. All clinical investigations of devices to determine safety and effectiveness must be conducted in accordance with the FDA’s investigational device exemption, or IDE, regulations which govern investigational device labeling, prohibit promotion of the investigational devices, and specify an array of recordkeeping, reporting and monitoring responsibility of study sponsors and study investigators. If the device presents a “significant risk,” as defined by the FDA, to human health, the FDA requires the device sponsor to submit an IDE application to the FDA, which must be approved prior to commencing human clinical trials. A significant risk device is one that presents a potential for serious risk to the health, safety or welfare of a patient and either is implanted, purported or represented to be used in supporting or sustaining human life, is for a use that is substantially important in diagnosing, curing, mitigating or treating disease or otherwise preventing impairment of human health, or otherwise presents a potential for serious risk to a subject. An IDE application must be supported by appropriate data, such as animal and laboratory test results, showing that it is safe to test the device in humans and that the testing protocol is scientifically sound. A clinical trial may begin 30 days after receipt of the IDE application by the FDA unless the FDA notifies the company that the investigation may not begin. If the FDA determines that there are deficiencies or other concerns with an IDE for which it requires modification, the FDA may permit a clinical trial to proceed under a conditional approval. Acceptance of an IDE application for review does not guarantee that the FDA will approve the IDE and, if it is approved, the FDA may or may not determine that the date derived from the trials support the safety and effectiveness of the device or warrant the continuation of clinical trials. An IDE supplement must be submitted to, and approved by, the

Table of Contents

FDA before a sponsor or investigator may make a change to the investigational plan that may affect its scientific soundness, study plan or the rights, safety or welfare of human subjects.

In addition, the study must be approved by, and conducted under the oversight of, an institutional review board, or IRB, for each clinical site. The IRB is responsible for the initial and continuing review of the IDE, and may pose additional requirements for the conduct of the study. If an IDE application is approved by the FDA and one or more IRBs, human clinical trials may begin a specific number of investigational sites with a specific number of patients, as approved by the FDA.

If the device is considered a “non-significant risk,” an IDE application to the FDA is not required. Instead, only approval from the IRB overseeing the investigation at each clinical trial site is required. Abbreviated IDE requirements, such as monitoring the investigation, ensuring that the investigators obtain informed consent, and labeling and record-keeping requirements also apply to non-significant risk device studies.

During a study, the sponsor is required to comply with the applicable FDA requirements, including, for example, trial monitoring, selecting clinical investigators and providing them with the investigational plan, ensuring IRB review, adverse event reporting, record keeping and prohibitions on the promotion of investigational devices or on making safety or effectiveness claims for them. The clinical investigators in the clinical study are also subject to FDA’s regulations and must obtain patient informed consent, rigorously follow the investigational plan and study protocol, control the disposition of the investigational device, and comply with all applicable reporting and record keeping requirements.

Additionally, after a trial begins, we, the FDA or the IRB could suspend or terminate a clinical trial at any time for various reasons, including a belief that the risks to study subjects outweigh the anticipated benefits. Even if a clinical trial is completed, there can be no assurance that the data generated during a clinical study will meet the safety and effectiveness endpoints or otherwise produce results that will lead the FDA to grant marketing clearance or approval. Information about certain device clinical trials must be posted on clinicaltrials.gov.

Pervasive and Continuing FDA Regulation

After a device is placed on the market, regardless of its classification or premarket pathway, numerous regulatory requirements apply. These include, but are not limited to:

establishment registration and device listings with the FDA;

QSR, which require manufacturers to follow stringent design, testing, process control, documentation and other quality assurance procedures;

labeling regulations, which prohibit the promotion of products for uncleared or unapproved, i.e. , “off-label,” uses and impose other restrictions on labeling;

medical device reporting regulations, which require that manufacturers report to the FDA if their device may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur;

corrections and removal reporting regulations, which require that manufacturers report to the FDA field corrections and product recalls or removals if undertaken to reduce a risk to health posed by the device or to remedy a violation of the U.S. Federal Food, Drug, and Cosmetic Act, or FDCA, that may present a risk to health; and

requirements to conduct post-market surveillance studies to establish continued safety data.

Table of Contents

The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcement action by the FDA, which may include any of the following sanctions:

untitled letters or warning letters;

fines, injunctions and civil penalties;

recall or seizure of our products;

operating restrictions, partial suspension or total shutdown of production;

refusing our request for 510(k) clearance or premarket approval or de novo classification of new products;

withdrawing premarket approvals that are already granted or reclassifying the devices; and

criminal prosecution.

We are subject to unannounced device inspections by the FDA and the California Food and Drug Branch. These inspections may include our suppliers’ facilities.

Third-Party Coverage and Reimbursement

We cannot control whether or not providers who use QuantaFlo will seek third-party coverage for such procedures or reimbursement. If providers intend to seek third-party coverage or reimbursement for use of QuantaFlo, the success of our product could become dependent on the availability of coverage and reimbursement from third-party payors, such as governmental programs including Medicare and Medicaid, private insurance plans and managed care programs. Reimbursement is contingent on established coding for a given procedure, coverage of the codes by the third-party payors and adequate payment for the resources used.

Physician coding for procedures is established by the American Medical Association. CMS, the agency responsible for administering Medicare and Medicaid, and the National Center for Health Statistics, are jointly responsible for overseeing changes and modifications to billing codes used by hospitals for reporting inpatient procedures, and many private payors rely on coverage decisions and reimbursement rates established by CMS as benchmarks for determining their own coverage and reimbursement policies. All physician and hospital coding is subject to change, which could impact coverage and reimbursement and physician practice behavior. We do not track denial of requests for reimbursement made by the users of QuantaFlo. It is our belief that such denials have occurred and might occur in the future with more or less frequency. We are not in the business of performing QuantaFlo measurements that require us to seek reimbursement from third-party payors, including governmental healthcare programs, such as Medicare and Medicaid, commercial health insurers, including those that offer Medicare Advantage plans, and managed care programs. Many of our customers are third-party payors who pay us directly for use of our product and services.

Independent of the coding status, third-party payors may deny coverage based on their own criteria, such as if they believe that the clinical efficacy of a device or procedure is not well established and is deemed experimental or investigational, is not the most cost-effective treatment available, or is used for an unapproved indication. We will continue to provide the appropriate resources to patients, physicians, hospitals and insurers in order to promote the best in patient care and clarity regarding reimbursement and work to obtain appropriate coverage policies. For some governmental programs, such as Medicaid, coverage and reimbursement differ from state to state, and some state Medicaid programs may not pay an adequate amount for the procedures performed with our products, if any payment is made at all. As the portion of the U.S. population over the age of 65 and eligible for Medicaid continues to grow, we may be more vulnerable to coverage and reimbursement limitations imposed by CMS. National and regional coverage policy decisions are subject to unforeseeable change and have the potential to impact physician behavior. For example, if CMS decreases the monthly payment for a 65-year-old patient, then the provider will have to decide which steps to eliminate from his or her routine office visits in order to maintain a profitable business model. If the time of an office

Table of Contents

visit will need to be reduced to maintain a profitable business, a provider may decide to eliminate certain services or conducting certain procedures, such as deciding not to use a thermometer, take someone’s blood pressure or use a QuantaFlo to run an ABI test. Thus, reimbursement limitations imposed by CMS on providers may affect their decision making about which services to provide during an office visit, which could affect our company.

Particularly in the United States, third-party payors carefully review, have undertaken cost-containment initiatives, and increasingly challenge the prices charged for procedures and medical products as well as any technology that they, in their own judgment, consider experimental or investigational. In addition, an increasing percentage of insured individuals are receiving their medical care through managed care programs, which monitor and often require pre-approval or pre-authorization of the services that a member will receive. Many managed care programs are paying their providers on a capitated basis, which puts the providers at financial risk for the services provided to their patients by paying them a predetermined amount per member per month. The percentage of individuals covered by managed care programs is expected to grow in the United States over the next decade.

There can be no assurance that third-party coverage and reimbursement will be available or adequate, or that future legislation, regulation, or coverage and reimbursement policies of third-party payors will not adversely affect the demand for our products or our ability to sell these products on a profitable basis. The unavailability or inadequacy of third-party payor coverage or reimbursement could have a material adverse effect on our business, operating results and financial condition.

Healthcare Fraud and Abuse

Our operations may be subject to federal and state healthcare laws and regulations including fraud and abuse laws, such as anti-kickback and false claims laws, data privacy and security laws and transparency laws related to payments and/or other transfers of value made to physicians and other healthcare professionals and teaching hospitals.

The federal Anti-Kickback Law prohibits unlawful inducements for the referral of business reimbursable under federally-funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursable by Medicare or Medicaid. The federal Anti-Kickback Law is subject to evolving interpretations. For example, the government has enforced the federal Anti-Kickback Law to reach large settlements with healthcare companies based on, among other things, inappropriate consultant arrangements with physicians or questionable joint venture arrangements. The majority of states also have anti-kickback laws, which establish similar prohibitions that may apply to items or services reimbursed by any third-party payor, including commercial insurers. Further, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively the Health Care Reform Law, among other things, amended the intent requirement of the federal Anti-Kickback Law and criminal healthcare fraud statutes. A person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it in order to have committed a violation. In addition, the Health Care Reform Law provided that the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Law constitutes a false or fraudulent claim for purposes of the civil False Claims Act and certain criminal healthcare fraud statutes.

Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S. government. Actions under the False Claims Act may be brought by the U.S.Attorney General or as a qui tam action by a private individual in the name of the government. The federal government is using the civil False Claims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide variety of Medicare billing practices and has obtained multi-million and multi-billion dollar settlements in addition to individual criminal convictions. The federal False Claims Act provides for treble damages and per-claim penalties. We have been cooperating with civil investigative demands from DOJ since 2017 related to claims for reimbursement related to our QuantaFlo device, and are at risk of civil suit by DOJ resulting therefrom. See Item 3. “Legal Proceedings” and Item 1A. “Risk Factors—We are subject to various healthcare fraud and abuse laws and regulations, and at risk that DOJ will file a complaint or complaint in intervention in a civil False Claims Act lawsuit seeking damages for tests performed using our device, which would adversely affect our business. A civil suit by DOJ also exposes us to risk of other litigation.” for more information. In addition, off-label promotion has been pursued as a violation of the federal False Claims Act. Pursuant to FDA

Table of Contents

regulations, we can only market our products for cleared or approved uses. Although physicians are permitted to use medical devices for indications other than those cleared or approved by the FDA based on their independent medical judgment, we are prohibited from promoting products for such off-label uses. Given the significant size of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ and suppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.

Additionally, the majority of states in which we market our products have similar fraud and abuse laws, such as anti-kickback, false claims, anti-fee splitting and self-referral laws, which may apply to items or services reimbursed by any third-party payor, including commercial insurers, and violations may result in substantial civil, criminal and administrative penalties.

The Health Care Reform Law also included the federal Physician Payments Sunshine Act, which requires device manufacturers for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program to disclose annually to CMS any “transfer of value” made or distributed to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), other licensed health care practitioners, and teaching hospitals. Such information is now made publicly available in a searchable format, and device manufacturers are now required to report and disclose any investment interests held by physicians and their family members during the preceding calendar year. Failure to submit required information may result in significant civil monetary penalties for all payments, transfers of value or ownership or investment interests not reported in an annual submission. Additionally, the commercial compliance environment is continually evolving in the healthcare industry, and some states, including California, Massachusetts and Vermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration to physicians and other healthcare providers. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictions with different compliance and/or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.

Our business operations may also be subject to certain federal and state laws regarding the use and disclosure of individually identifiable health information, such as the federal Health Insurance Portability and Accountability Act of 1996, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, which impose obligations on certain entities with respect to safeguarding the privacy, security and transmission of individually identifiable health information.

To enforce compliance with the federal laws, the DOJ has also increased its scrutiny of interactions between healthcare companies and healthcare providers, which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry (including our company). Dealing with investigations can be time- and resource-consuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies, the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.

The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry, including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we are not in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain or seize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and can recommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.

Table of Contents

If a governmental authority were to conclude that we are not in compliance with applicable fraud and abuse laws and regulations, we and our officers and employees could be subject to severe penalties including, for example, civil, criminal and administrative penalties, damages, fines, disgorgement, individual imprisonment, exclusion from participation as a supplier of product to beneficiaries covered by Medicare or Medicaid, additional reporting obligations and oversight if subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, contractual damages, reputational harm, diminished profits and future earnings, and curtailment or restructuring of operations, any of which could adversely affect our ability to operate our business and the results of our operations.

It is uncertain whether and how future legislation, whether domestic or foreign, could affect prospects for QuantaFlo or what actions foreign, federal, state or private payors for health care treatment and services may take in response to any such health care reform proposals or legislation.

Healthcare Reform

Political, economic and regulatory influences are subjecting the healthcare industry to fundamental changes. For example, the Health Care Reform Law significantly changed the health care industry and brought a new way of doing business for providers and health insurance plans.

There have been executive, judicial and Congressional challenges to certain aspects of the Health Care Reform Law. For example, several executive orders were issued along with other directives designed to delay the implementation of certain provisions of the Health Care Reform Law or otherwise circumvent some of the requirements for health insurance mandated by the Health Care Reform Law. Concurrently, Congress considered legislation that would repeal or repeal and replace all or part of the Health Care Reform Law. While Congress has not passed comprehensive repeal legislation, it has enacted laws that modify certain provisions of the Health Care Reform Law such as removing penalties, effective January 1, 2019, for not complying with the Health Care Reform Law’s “individual mandate” to carry health insurance, delaying the implementation of certain Health Care Reform Law-mandated fees, and repealing the medical device excise tax. In June 2021, in an appeal from a lower court decision holding that the individual mandate under the Health Care Reform Law is unconstitutional, the United States Supreme Court ruled that the plaintiffs lacked standing to challenge the law as they had not alleged personal injury traceable to the allegedly unlawful conduct. As a result, the Supreme Court did not rule on the constitutionality of the Health Care Reform Law. It is unclear how additional litigation or executive orders will impact the Health Care Reform Law and our business.

Other legislative changes have been proposed and adopted in the United States since the passage of the Health Care Reform Law. For example, through the process created by the Budget Control Act of 2011 and subsequent legislation, there are automatic reductions of Medicare payments to providers of generally 2% per fiscal year; these reductions went into effect in April 2013 and will remain in effect through fiscal year 2031 unless additional Congressional action is taken.

Additionally, there has been increasing legislative and enforcement interest in the United States with respect to cost-containment initiatives within the health care industry. We cannot predict what healthcare reform initiatives may be adopted in the future, particularly in light of the new presidential administration. Further, it is possible that additional governmental action is taken in response to pandemics.

Human Capital Management

As of December 31, 2024, we had 79 employees, all of which were full-time. None of our employees are represented by a labor union, and we consider our relationship with our employees to be positive. We also regularly engage consultants and subcontractors on an as-needed basis.

Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating our existing and additional employees. We use different incentive plans such as annual cash bonuses, no-cost healthcare for employees and their families, paid vacation for employees ranked below director and generous referral

Table of Contents

bonuses to attract, retain and motivate our employees. From time to time, we may also provide equity incentives, such as stock option grants.

Governance and Culture - Our board of directors, including committees thereof, and executive management team are actively involved in overseeing our employee-related strategies and practices as well as our company culture. Our director of human resources and her team are also actively involved in implementing these decisions. We believe our company culture has been a critical component of our success in attracting and retaining personnel.

Inclusion - We aim to create an inclusive working environment where all employees are respected and treated equally. Our policy is that we do not discriminate based on race, religious creed, color, national origin, ancestry, physical disability, mental disability, medical condition, genetic information, marital status, sex, gender, gender identity, gender expression, age, military and veteran status, sexual orientation or any other protected characteristics established by federal, state or local laws. This message is emphasized from the top of our organization down to all of our employees.

Health, Safety and Well-Being - The safety and well-being of our employees is critical to our successful operation. Our health and safety activities are overseen by our board of directors, executive management team and director of human resources. Most of our employees work remotely, with the exception of a few employees who work in the office. These employees are generally in fulfillment and sales support roles. Our human resources department coordinates on-line training programs with the help of outside consultants. We believe that this model of training better fits our business operations and needs.

ITEM 1A. RISK FACTORS

Any investment in our securities involves a high degree of risk. Investors should carefully consider the risks described below and all of the information contained in this annual report on Form 10-K before deciding whether to purchase our common stock. Our business, financial condition or results of operations and trading price or value of our securities could be materially adversely affected by these risks if any of them actually occur. This annual report on Form 10-K also contains forward-looking statements that involve risks and uncertainties. See “Cautionary Note Regarding Forward-Looking Statements and Industry Data.” Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks we face as described below and elsewhere in this annual report on Form 10-K.

Risks Related to Our Business

If we do not successfully implement our healthcare solutions strategy, our business and results of operations will be adversely affected.

Our business strategy was formed based on assumptions about the cardiac and vascular diseases market and healthcare reform that might prove wrong. We believe that various demographics and industry-specific trends, including the aging of the general population, growth of capitated payment programs, numbers of undiagnosed patients with cardiac and vascular or other diseases and the importance of codifying vascular disease and potentially other diseases will help drive growth in the cardiac and vascular diseases market and our risk assessment business. However, these demographics and trends, and our assumptions about them, are uncertain. Actual demand for our products and service offerings could differ materially from projected demand if our assumptions regarding these factors prove to be incorrect or do not materialize, or if alternatives to our products or other risk assessment service providers gain widespread acceptance. Moreover, if our customers do not receive increased capitated payments for providing care to patients for PAD using our products, it would have material and adverse effect on our business, financial condition and results of operations. For example, CMS revised the hierarchical condition category, or HCC, codes for vascular disease and created uncertainty in the future whether identifying patients with PAD will qualify for an increased capitated payment. More specifically, i n late March 2023, CMS issued a final 2024 rate announcement with payment changes for the Medicare Advantage and Part D prescription drug programs and under which CMS is phasing in a new Medicare Advantage risk adjustment model (2024 model) from the previous model (2020 model) over a three-year period. The 2024 model did not include risk adjusted payments for PAD without complications, which payments many health insurers have previously relied upon for their Medicare Advantage patients under the previous 2020 model. These

Table of Contents

changes are being phased in as follows: in calendar year 2023, full payment under the 2020 model continued; in calendar year 2024, 67% of the 2020 model is available; in calendar year 2025, 33% of the 2020 model will be available . Such changes in the regulatory landscape for HCC codes has impacted the perceived profitability of using QuantaFlo to aid diagnosis of cardiovascular diseases. We are experiencing and expect to continue to experience decreased usage due to the current CMS reimbursement landscape, which is having a negative effect on our revenues.

In addition, we may not be able to successfully implement our business strategy. To implement our business strategy, we need to (among other things) find new applications for and improve our products and service offerings and educate healthcare providers and plans about the clinical and cost benefits of our products, all of which we believe could increase acceptance of our products by physicians. We have ceased marketing of QuantaFlo as an aid in the diagnosis of heart dysfunction and there is no guarantee that we will obtain a new FDA 510(k) clearance for the expanded use. Although we have the right from time to time to distribute other third-party products, there is no guarantee that we will be successful. For example, although we had a distribution agreement for Insulin Insights from Mellitus, we were not able to generate significant revenue and wrote off the entire balance of our $2.5 million investment in December 2023. We may also need to develop or acquire rights to other products and services that would be of interest to our customers given the patient populations they serve. In addition, we are seeking to increase our sales and, in order to do so, might need to continue to expand our direct and distributor sales forces in existing and new territories, which could subject us to additional or different regulatory requirements with which we may not be able to comply. Moreover, even if we successfully implement our business strategy, our operating results may not improve or may decline. We may decide to alter or discontinue aspects of our business strategy and may adopt different strategies due to business or competitive factors not currently foreseen, such as new medical technologies that would make our products obsolete or changes in the regulatory landscape that may undermine the economic rationale for QuantaFlo or difficulties in obtaining a new 510(k) clearance, which could cause us to cease efforts to expand the indications for QuantaFlo. Our attempts to alter aspects of our business strategy, such as our prior entry into an exclusive marketing and distribution agreement and our investments in private companies, may not yield positive effects on our business, results of operations and financial condition. Any delay or failure to implement our business strategy may adversely affect our business, results of operations and financial condition.

We predominantly market only one FDA-cleared vascular testing product; it may not achieve broad market acceptance or be commercially successful. We may also fail to generate meaningful benefit from our recent investments in other companies developing complementary products or distribution agreements for complementary products.

We currently actively market only one vascular testing product, QuantaFlo and have a distribution agreement for a third-party product. Although we had an exclusive marketing and distribution agreement for another product (Insulin Insights), we did not generate meaningful distribution revenues and we wrote off our prepaid licenses and a portion of our investment in December 2023. We also have a few minority investments in other companies but we do not distribute their products (see Note 6 to our audited financials appearing elsewhere in this annual report on Form 10-K for additional information relating to these minority investments). There is a risk that we may never receive repayment of our loans, nor receive any benefit from our equity investment, nor that we will generate meaningful revenues from our existing distribution arrangement. Accordingly, we expect that revenues from our vascular testing product will account for the vast majority of our revenues for at least the next several years.

Table of Contents

QuantaFlo, and any other products we may be offering in the future, may not gain broad market acceptance unless we continue to educate physicians and plans of their benefits. Moreover, even if insurance plans, home health care providers and physicians understand the benefits of cardiovascular and other risk assessment testing, they still may elect not to use our products for a variety of reasons, such as familiarity with other devices and approaches, or the impact of CMS regulatory revisions, which revised the regulatory landscape for HCC codes and has impacted the perceived profitability of using QuantaFlo to aid diagnosis of cardiovascular diseases. We may not be successful in gaining market acceptance of a technique measuring comparative blood flows using our proprietary algorithm to indicate flow obstruction as opposed to existing techniques that measure comparative blood pressures using well-accepted criteria to indicate flow obstruction, or imaging techniques that visualize anatomy of the arteries. Providers may also object to renting an examining tool with ongoing monthly payments rather than making a one-time capital purchase or be reluctant to pay monthly fees for tools in the examining room when they have many such tools, such as thermometer and stethoscope that only required one-time minimal purchases. Providers may also not synch their devices as required per their service contracts in the fee-per-test (variable license fees) model, and thus we may not capture all revenue to which we are entitled.

If QuantaFlo or other products we may offer are not viewed as an attractive alternative to other products, procedures and techniques, we will not achieve significant market penetration or be able to generate significant revenues. To the extent that any products we offer are not commercially successful or are withdrawn from the market for any reason, our revenues will be adversely impacted, and our business, operating results and financial condition will be harmed.

Physicians and other customers may not widely adopt our products unless they determine, based on experience, long-term clinical data and published peer reviewed journal articles, that the use of our products provides a safe and effective alternative to other existing ABI devices.

We believe that physicians and other customers will not widely adopt our vascular testing product or our other products in development or products we distribute unless they determine, based on experience, long-term clinical data and published peer reviewed journal articles, that the use of such product provides a safe and effective alternative to other existing ABI devices.

We cannot provide any assurance that the data collected from our past, current and any future clinical trials will be sufficient to demonstrate that our products are an attractive alternative to other ABI devices or procedures. If we fail to demonstrate safety and efficacy that is at least comparable to other ABI devices that are available on the market, our ability to successfully market our products will be significantly limited. Even if the data collected from clinical studies or clinical experience indicate positive results, each physician’s actual experience with our products will vary. We also believe that published peer-reviewed journal articles and recommendations and support by influential physicians regarding our vascular testing product and our other products in development will be important for market acceptance and adoption, and we cannot assure you that we will receive these recommendations and support, or that supportive articles will be published. Accordingly, there is a risk that our products may not be adopted by many physicians, which would negatively impact our business, financial condition and results of operations.

Moreover, for any complementary products for which we have (or acquire) exclusive distribution rights, we may not be able to convince potential customers of their benefits, and these rights and potential future rights may not generate any meaningful revenues for our company.

If healthcare providers are unable to obtain adequate coverage and reimbursement either for procedures performed using our product or patient care incorporating the use of our product, our product might have difficulty gaining widespread acceptance.

Maintaining and growing revenues from our products and service offerings depends on the availability of coverage and adequate reimbursement from third-party payors, including government programs such as Medicare and Medicaid, private insurance plans and managed care programs. Healthcare providers that use medical devices such as QuantaFlo to test their patients generally rely on third-party payors to pay for all or part of the costs and fees associated with the procedures performed with these devices, or to compensate them for their patient care services. The existence of coverage and adequate reimbursement for the procedures or patient care performed with QuantaFlo by third-party payors

Table of Contents

is central to the acceptance of QuantaFlo and any future products. During the past several years, third-party payors have undertaken cost-containment initiatives including different payment methods, monitoring healthcare expenditures, and anti-fraud initiatives. We may not be able to achieve or maintain profitability if third-party payors deny coverage or reduce their current levels of payment, or if our costs of production increase faster than increases in reimbursement levels. Further, many private payors use coverage decisions and payment amounts determined by CMS, which administers the Medicare program, as guidelines in setting their coverage and reimbursement policies. Those private payors that do not follow the Medicare guidelines may adopt different coverage and reimbursement policies for procedures or patient care performed with our vascular testing product. Future action by CMS or other government agencies may diminish payments to physicians, outpatient centers and/or hospitals or may undermine the economic rationale for using QuantaFlo if there is no increased capitated payment for the vascular diseases it helps diagnose. For example, the final 2024 CMS rate announcement for Medicare Advantage and Medicare Part D did not include risk-adjusted payments for PAD without complications, which is leading to decreased usage of our product and negatively affecting our revenues. For some governmental programs, such as Medicaid, coverage and reimbursement differ from state to state, and some state Medicaid programs may not pay an adequate amount for the procedures or patient care performed with QuantaFlo if any payment is made at all. As the portion of the U.S. population over the age of 65 and eligible for Medicare continues to grow, we may be more vulnerable to coverage and reimbursement limitations imposed by CMS. Furthermore, the healthcare industry in the United States has experienced a trend toward cost containment as government and private insurers seek to control healthcare costs by imposing lower payment rates and negotiating reduced contract rates with service providers. Therefore, we cannot be certain that the procedures or patient care performed with our product will be reimbursed at a cost-effective level.

QuantaFlo is not specifically approved for reimbursement under any third-party payor codes; if third-party payors refuse to reimburse our customers for their use of our product, it could have a material adverse effect on our business.

QuantaFlo is licensed by healthcare providers. They may bill various third-party payors, including governmental healthcare programs, such as Medicare and Medicaid, private insurance plans and managed care programs for procedures in which our testing product is used. Reimbursement is a significant factor considered by healthcare providers in determining whether to license medical devices or systems such as QuantaFlo. We cannot control whether or not providers who use QuantaFlo will seek reimbursement. Therefore, our ability to successfully commercialize our vascular testing product could depend on the coverage and adequacy of reimbursement from these third-party payors.

Currently, our QuantaFlo device is not specifically approved for any particular reimbursement code. Although some of our customers report being covered and reimbursed by third-party payors for procedures, we have not offered any reimbursement guidance, therefore there is a risk that third-party payors may disagree with the reimbursement under a particular code. In addition, some of our potential customers might have deferred renting our product given the uncertainty regarding reimbursement. We do not track denial of requests for reimbursement made by the users of our product. It is our belief that such denials have occurred and might occur in the future with more or less frequency. Even if our product and procedures are often currently covered and reimbursed by third-party payors and Medicare, problems for customers to receive reimbursement or adverse changes in payors’ coverage and reimbursement policies that affect our product could harm our ability to market our vascular testing product. Obtaining approval for a particular reimbursement code is time consuming and can be costly. Accordingly, at this time, and given the way we intend our QuantaFlo to be used, we do not intend to pursue formal approval for QuantaFlo for any particular code.

Moreover, we are unable to predict what changes will be made to the reimbursement methodologies used by third-party payors. We cannot be certain that under current and future payment systems, in which healthcare providers may be reimbursed a set amount based on the type of procedure performed, such as those utilized by Medicare and in many privately managed care systems, the cost of our product will be justified and incorporated into the overall cost of the procedure.

We rely heavily upon the talents of a small number of key personnel, the loss of whom could severely damage our business.

Table of Contents

Our performance depends to a large extent on a small number of key scientific, technical, managerial and marketing personnel. We do not maintain key man insurance for any of our personnel. The loss of the services of any of these key personnel could still severely damage our business prospects, which could have a material adverse effect on our financial condition and results of operations.

We rely on a small number of employees in our direct sales force and face challenges and risk in managing and maintaining our distribution network and the parties who make up that network.

We face significant challenges and risks in managing our distribution network and retaining the parties who make up that network. We had 45 sales and marketing employees as of December 31, 2024. If any of our sales or marketing force were to resign, our sales could be adversely affected. We may need to seek out alternatives, such as increasing our direct sales and marketing force or contracting with an independent distributor. There is no guarantee that we would be successful in our efforts to find an independent distributor, or that we would be able to negotiate contract terms favorable to us. Failure to hire or retain qualified direct sales and marketing personnel or independent distributors would prevent us from expanding our business and generating revenues, which would have a material adverse effect on our ability to achieve or maintain profitability.

To adequately commercialize our products and any new products we add, we may need to increase our sales and marketing network, which will require us to hire, train, retain and supervise employees and other independent contractors .

We are currently exploring other sales models to generate revenues from our products in addition to the leasing model, such as our fee per test model. We have and also may in the future acquire rights to other complementary products. As we increase our marketing efforts to pursue these new strategies and expand our efforts to target insurance plans that serve Medicare Advantage members, we may need to increase our sales and marketing network. Our future success will depend largely on our ability to continue to hire, train, retain and motivate skilled direct sales representatives, or independent distributors with significant technical knowledge about our product and complementary products we distribute, in addition to coordinating networks of contract medical assistants and other personnel to staff health and wellness fairs and physicians’ offices in fee-for-service models. New hires and independent distributors require training, supervision and take time to achieve full productivity. If we fail to train and supervise new hires adequately, or if we experience high turnover in our sales force or trained professionals in the future, we cannot be certain that we will maintain or increase our sales. If we are unable to expand our sales and marketing capabilities, we may not be able to effectively commercialize QuantaFlo or our other products and service offerings in development or that we distribute, which would adversely affect our business, results of operations and financial condition.

We do not require our customers to enter into long-term licenses or maintenance contracts for our products or services and may therefore lose customers on short notice.

Our business is primarily based on a leasing model rather than an outright sale of our products although we also generate variable fee revenues, which are based on usage (fee-per-test). Our pricing is based on data collected on use rates and third-party payment rates to physicians and facilities for the use of our product. We require no down payment, long-term commitment or maintenance contract or fees from our customers and may replace damaged products free of charge in the service model. If we lose current customers on short notice, we may not be able to find new customers to replace them with in a timely manner and that could adversely affect our business, results of operations and financial condition. In addition, our business model of replacing damaged products free of charge may prove to be costly and affect the profitability of our service model. In our fee-per-test model, we rely on our customers to comply with the terms of service that require them to synchronize devices on a regular and routine basis such that we are able to invoice them for the tests done using our device. There is a risk that customers use our device without synching as agreed, which could lead to inadequate billing and failing to capture revenue based on actual usage. Although we have procedures in place to limit usage of our device if it has not synchronized for a period of time, there is no guarantee that our customers will act in compliance with their terms of service and we may not appropriately capture all per-test fees to which we are entitled.

We are exposed to risk as a significant portion of our revenues and accounts receivables are with a limited number of customers.

A limited number of customers account for a significant portion of our revenues and accounts receivable. F or the year ended December 31, 2024, two customers (including their affiliates) accounted for 43.1% and 27.6% of our revenues, respectively. As of December 31, 2024, three customers accounted for 33.9%, 28.7% and 14.0% of our accounts receivable. If our largest customers were to cease using or stop payment for our vascular testing devices or leverage their market share to negotiate reduced pricing terms, it would have a material adverse effect on our revenues and/or our accounts receivable. Our efforts to diversify and potentially expand our product offering are preliminary in nature. This concentration of revenues and accounts receivable among a limited number of customers represents a significant risk.

We rely on a small number of independent suppliers and facilities for the manufacturing of QuantaFlo. Any delay or disruption in the supply of the product or facility may negatively impact our operations.

We manufacture QuantaFlo through a small number of independent contractors based in the United States. We also have a distribution agreement for a third-party complementary product that they are contractually obligated to supply to us. The loss or disruption of our relationships with outside vendors and suppliers, including failure to adhere to contractual terms, could subject us to substantial delays in the delivery to customers. Our current contractor manufacturers source some supplies from China and should these outside vendors encounter issues due to supply chain disruptions as a result of the recent tariff proposals of the current U.S. administration, or a global health emergency such as COVID-19 pandemic or otherwise, we believe alternative suppliers should be available. However, significant delays in the delivery of our product or inventory to us could result in possible cancellation of orders and the loss of customers. Although we expect our vendors and suppliers to comply with our contract terms, we do not have control over such parties. Our inability to provide a product that meets delivery schedules could have a material adverse effect on our reputation in the industry, which could have a material adverse effect on our financial condition and results of operations .

Further, QuantaFlo is manufactured in the United States in a limited number of facilities. If an event occurred that resulted in material damage to these manufacturing facilities or our manufacturing contractors lacked sufficient labor to fully operate their facilities, we may be unable to transfer the manufacture of QuantaFlo to another facility or location in a cost-effective or timely manner, if at all. This potential inability to transfer production could occur for a number of reasons, including but not limited to a lack of necessary relevant manufacturing capability at another facility, or the regulatory requirements of the FDA or other governmental regulatory bodies. Even if there are many qualified contract manufacturers available around the country and our product is relatively easy to manufacture, such an event could have a material adverse effect on our financial condition and results of operations.

We will need to generate significant revenues to remain profitable .

We will need to generate significant sales to maintain profitability in our healthcare solutions business and we might not be able to do so. Even if we do generate significant sales, we might not be able to sustain or increase profitability on a quarterly or annual basis in the future. If our sales decline or grow more slowly than we anticipate or if our operating expenses exceed our expectations, our financial performance from our operating business will likely be adversely affected.

Our future financial performance will depend in part on the successful improvements and software updates to QuantaFlo on a cost-effective basis .

Our future financial performance will depend in part on our ability to anticipate, identify and respond to changing user preferences and needs and the technologies relating to the care and treatment of vascular problems. We can provide no assurances that QuantaFlo will achieve significant commercial success and that it will gain meaningful market share. We may not correctly anticipate or identify trends in user preferences or needs or may identify them later than competitors do. In addition, difficulties in manufacturing or in obtaining regulatory approvals may delay or prohibit

Table of Contents

improvements to QuantaFlo or our other products in development. Further, we may not be able to develop improvements and software updates to QuantaFlo at a cost that allows us to meet our goals for profitability. Service costs relating to our product may be greater than anticipated, rentals may be returned prior to the end of the license term, and we may be required to devote significant resources to address any quality issues associated with QuantaFlo.

Failure to successfully introduce, improve or update our products on a cost-effective basis, or delays in customer decisions related to the evaluation of our products could cause us to lose market acceptance and could materially adversely affect our business, financial condition and results of operations.

One of our business strategies is developing or distributing additional products and service offerings that allow healthcare providers to deliver cost-effective wellness programs and receive increased compensation for their services. The development or distribution of new products and service offerings involves time and expense and we may never realize the benefits of this investment.

As part of our business strategy, we intend to develop or distribute additional products and service offerings that allow healthcare providers to deliver cost-effective wellness programs. Such new product and service offering may require substantial investments and we may commit significant resources and time before knowing whether our efforts will translate into profits for our company. We may continue to choose to invest some of our cash resources in other entities that may have complementary technologies or product offerings and may not realize the benefit of such investments. For example, in December 2023, we wrote off the $2.5 million prepayment for Insulin Insights software licenses as we were not able to generate meaningful revenues, and also took a $0.6 million impairment charge on our investment in Mellitus. It is possible that our development or distribution efforts will not be successful and that we will not be able to develop new products or service offerings, either alone or in partnership with others, or if developed that we will obtain the necessary regulatory approvals for commercialization. Even if we receive necessary regulatory approvals, there is no guarantee that such approved products or any new service offerings or any third-party products that we distribute will achieve market acceptance and we may never realize the benefits of any investment in this strategy.

We have used our cash resources to invest in other companies, and there is no guarantee that we will be repaid on maturity nor realize any other expected benefits from such investments, which could harm our business.

From time to time, we have invested, and may in the future invest, in other companies with potentially complementary products or technologies. For example, in September and October 2020, we made investments in Mellitus and SYNAPS Dx, two private companies working in other product areas, Insulin Insights and Discern, and in December 2022, we extended a loan to Monarch, maker of the software product EndoTool and such loan as amended in December 2024 and January 2025. There can be no assurance that the businesses we invest in will become profitable or remain so or that we will realize any financial benefit from our investments, including whether or not we will distribute Discern and EndoTool or that we will be repaid upon maturity of our loans. Notably, in the year ended December 31, 2023, we wrote-off our $2.5 million prepayment for Insulin Insights software licenses as we were not able to generate meaningful revenues, and also took a $0.6 million impairment charge on our investment in Mellitus. Additionally, investments in privately held companies are inherently risky, in some instances because the markets for the technologies or products these companies have under development may never materialize or achieve expectations. If these companies do not succeed, we may be forced to record additional impairment charges and could lose some or all of our investment in these companies. Further, we may need to divest our investments or increase our investment to become a controlling interest sooner than we may like in order to comply with regulations regarding the amount of our assets represented by minority investments. These regulatory requirements may not always coincide with our business objectives and could adversely affect our investments and strategy.

Risks Related to Our Legal and Regulatory Environment

Our business is subject to many laws and government regulations governing the manufacture and sale of medical devices, including the FDA’s 510(k) clearance process, and laws and regulations governing patient data and information, among others.

Our vascular testing product and any future medical devices that we may develop or services that we may offer are subject to extensive regulation in the United States by the federal government, including by the FDA. For example, our operations are subject to regulations governing packaging and labeling requirements, adverse event reporting, quality system and manufacturing requirements, clinical testing and recalls. For a discussion of the relevant regulatory regime, see “Business—Government Regulation” in Item 1 of this annual report on Form 10-K. We cannot assure that any new medical devices or new uses or modifications for QuantaFlo that we develop, including our planned 510(k) for the use of QuantaFlo to enable expanded labeling as an aid in the diagnosis of other cardiovascular diseases in addition to PAD, will be cleared or approved in a timely or cost-effective manner, if cleared or approved at all. Even if such clearances or approvals are received, they may not be for all indications. Because medical devices may only be marketed for cleared or approved indications, this could significantly limit the market for that product and may adversely affect our results of operations.

Furthermore, although QuantaFlo has received FDA clearance, we must make our own determination regarding whether a modification to the device requires a new clearance. For example, we are seeking a new 510(k) clearance from the FDA for the expanded use of QuantaFlo intended to enable expanded labeling as an aid in the diagnosis of other cardiovascular diseases in addition to PAD. We cannot guarantee that the FDA will agree with our decisions not to seek clearances for particular device modifications or that we will be successful in obtaining 510(k) clearances for modifications. Any such additional clearance processes with the FDA could delay our ability to market a modified product and may adversely affect our results of operations. We also may need to undertake a recall of any modified product that has been distributed.

The FDA may change its policies, adopt additional regulations, or revise existing regulations, in particular relating to the 510(k) clearance process.

The FDA may change its policies, adopt additional regulations, or revise existing regulations, each of which could prevent or delay premarket approval or 510(k) clearance of a device, or could impact our ability to market our currently cleared device. For example, in February 2024, the FDA published a final rule to amend its QSR, requirements to align more closely with the international consensus standards for medical devices by converging with quality management system, requirements used by other regulatory authorities from other countries. Specifically, the final rule does so primarily by incorporating by reference the 2016 edition of the International Organization of Standardization, or ISO, ISO 13485 standard. The amended regulation is referred to as the Quality Management System Regulation, and is effective February 2026. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing authorization that we may have obtained, which could have a material adverse effect on our business, prospects, results of operations, financial condition and our ability to achieve or sustain profitability. Further, future reforms could require us to file new 510(k)s and could increase the total number of 510(k)s to be filed. We cannot predict what effect these reforms will have on our ability to obtain 510(k) clearances in a timely manner. We also cannot predict the nature of other regulatory reforms and their resulting effects on our business.

Our business is subject to unannounced inspections by FDA to determine our compliance with FDA requirements .

FDA inspections can result in inspectional observations on FDA’s Form-483, warning letters, untitled letters or other forms of more significant enforcement action. More specifically, if FDA concludes that we are not in compliance with applicable laws or regulations, or that our vascular testing product or any future medical device we develop is ineffective or poses an unreasonable health risk, the FDA could:

require us to notify health professionals and others that our devices present unreasonable risk of substantial harm to public health;

Table of Contents

order us to recall, repair, replace or refund the cost of any medical device that we manufactured or distributed;

detain, seize or ban adulterated or misbranded medical devices;

refuse to provide us with documents necessary to export our product;

refuse requests for 510(k) clearance or premarket approval of new products or new intended uses;

withdraw the premarket approvals we may receive or reclassify our device;

impose operating restrictions, including requiring a partial or total shutdown of production;

enjoin or restrain conduct resulting in violations of applicable law pertaining to medical devices; and/or

assess criminal or civil penalties against our officers, employees or us.

Following correspondence from FDA questioning our reliance on letters-to-file for the expansion into heart dysfunction, we are now seeking a new 510(k) clearance from the FDA for the expanded use of QuantaFlo to enable expanded labeling. If the FDA concludes that we failed to comply with any regulatory requirement during an inspection or otherwise, it could have a material adverse effect on our business and financial condition. We could incur substantial expense and harm to our reputation, and our ability to introduce new or enhanced products in a timely manner could be adversely affected.

We may rely on third parties to support certain aspects of our clinical trials and regulatory processes. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory clearance or approval or commercialize our products, and our business could be substantially harmed .

We may retain the services of knowledgeable external service providers, including consultants and clinical research organizations, to develop and supervise our clinical trials and regulatory processes. These third-party contract research organizations and consultants may carry out portions of our clinical and preclinical research studies and regulatory filing assistance and as a result, if retained, we will have less control over the conduct of the clinical trials, the timing and completion of the trials, the required reporting of adverse events, and the management of data developed through the trials than would be the case if we were relying entirely on our own staff. Outside parties may have staffing difficulties, may undergo changes in priorities or may become financially distressed, adversely affecting their willingness or ability to conduct our trials. Failure by these third parties to comply with regulatory requirements or to meet timing expectations may require us to repeat clinical trials or preclinical studies, which would delay the regulatory clearance or approval process, or require substantial unexpected expenditures.

If we are found to have improperly promoted our products for off-label uses, we may become subject to significant fines and other liability.

FDA and other regulatory agencies strictly regulate the promotional claims that may be made about medical devices. For example, devices cleared under section 510(k) cannot be marketed for any intended use that is outside of FDA’s substantial equivalence determination for such devices. Physicians nevertheless may use our products on their patients in a manner that is inconsistent with the intended use cleared by FDA. If we are found to have promoted such “off-label” uses, we may become subject to significant government fines and other related liability. The federal government has levied large civil and criminal fines against companies for alleged improper promotion and has enjoined several companies from engaging in off-label promotion. FDA has also requested that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed.

Although part of our business strategy is based on payment provisions enacted under government healthcare reform, we also face significant uncertainty in the industry regarding the implementation, transformation or repeal and replacement of the Health Care Reform Law.

Political, economic and regulatory influences are subjecting the healthcare industry to fundamental changes. For example, the Health Care Reform Law brought a new way of doing business for providers and health insurance plans, shifting the focus from fee for service programs to capitated programs that pay a monthly fee per patient. The Health Care Reform law also provided for higher risk factor adjustment payments for sicker patients who have conditions that are codified, as well as economic benefits for achieving certain quality of care measurements. For a discussion of healthcare reform activity, see “Business—Government Regulation—Healthcare Reform” in Item 1 of this annual report on Form 10-K.

We believe that the Health Care Reform Law measures are mainly positive for our business given the ability of QuantaFlo to measure blood flow in an in-office setting, which can assist doctors and other providers to suspect PAD and other vascular diseases. However, we cannot predict what changes will now be made, and if these features will be repealed. If changes are made to the Health Care Reform Law, or it is repealed altogether without a comparable replacement, such that there are no incentives for identifying sicker patients, it would negatively affect our business prospects and strategy, and could materially adversely affect our business, financial condition and results of operations.

Further, the Health Care Reform Law encourages hospitals and physicians to work collaboratively through shared savings programs, such as accountable care organizations, as well as other bundled payment initiatives, which may ultimately result in the reduction of medical device acquisitions and the consolidation of medical device suppliers used by hospitals and health systems. Changes to or repeal of the Health Care Reform Law could adversely affect our financial results and business.

We are subject to various healthcare fraud and abuse laws and regulations, and at risk that DOJ will file a complaint or complaint in intervention in a civil False Claims Act lawsuit seeking damages for tests performed using our device, which would adversely affect our business. A civil suit by DOJ also exposes us to risk of other litigation.

We are subject to various healthcare fraud and abuse laws and regulations, as described “Business—Government Regulation—Healthcare Fraud and Abuse” in Item 1 of this annual report on Form 10-K. We may be subject to liability under such laws and may also be subject to liability for any future conduct that is deemed by the government or the courts to violate these laws, including significant administrative, criminal and civil penalties, damages, fines, disgorgement, imprisonment, exclusion from participation as a supplier of product to beneficiaries covered by Medicare or Medicaid, additional reporting obligations and oversight if subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, contractual damages, reputational harm, diminished profits and future earnings, and curtailment or restructuring of operations.

Additionally, the government has continued to pursue an increasing number of enforcement actions. This increased enforcement environment may increase scrutiny of us, directly or indirectly, and could increase the likelihood of an enforcement action targeting us, either due to our actions, those of any distributor (including our former distributor), or our customers or those of our distributors. These customers include parties that bill Federal healthcare programs for use of our product or for caring for patients with conditions diagnosed with the aid of our product, all of whom may be subject to government scrutiny. For example, DOJ has been investigating improper reimbursement of claims for testing using our QuantaFlo device. See Item 3 “Legal Proceedings.” There is a risk that the DOJ will file a complaint or complaint in intervention in a civil False Claims Act lawsuit seeking damages for tests performed using our device, which would adversely affect our business. The federal False Claims Act provides for treble damages and per-claim penalties. A civil suit by DOJ also exposes us to risk of other litigation. Finally, to the extent that any of the agreements are breached or terminated, our business may experience a decrease in revenues. In addition, to the extent that our customers, many of whom are providers, may be affected by this increased enforcement environment, our business could correspondingly be affected. It is possible that a review of our business practices or those of our customers by courts or government authorities could result in a determination with an adverse effect on our business. We cannot predict the effect of possible future enforcement actions on our business.

We have had material weaknesses in our internal control over financial reporting. Although we have remediated our prior material weaknesses, if we identify additional material weaknesses in the future, or if our former material weaknesses recur, it could have an adverse effect on our company.

In prior years, we have identified certain material weaknesses in connection with management’s evaluation of our internal control over financial reporting that we have remediated. These weaknesses have included issues arising from our size and inability to segregate duties; ineffective design of certain of our information technology and change management controls; insufficient controls to validate the completeness and accuracy of underlying data; insufficient protocols and procedures to retain adequate documentary evidence related to the timely review and approval of manual journal entries and those supporting the design and operating effectiveness of certain important management review controls; a lack of controls to identify and analyze related party transactions; a lack of technical accounting competence; and inadequate procedures and controls to appropriately comply with, and account for, certain payroll tax withholdings and related expenses.

Although we have remediated our prior material weaknesses, we cannot assure you that we have identified all material weaknesses or that we will not in the future have additional, or recurrence of our prior, material weaknesses in our internal control over financial reporting. If we have additional material weaknesses in our internal control over financial reporting in the future, or if our former material weaknesses recur, it could have an adverse effect on our company.

Risks Related to Our Intellectual Property

Our success largely depends on our ability to obtain and protect the proprietary information on which we base our product.

Our success depends in large part upon our ability to establish and maintain the proprietary nature of our technology through the patent process, as well as our ability to license from others’ patents and patent applications necessary to develop our product. If our patent or any future patents are successfully challenged, invalidated or circumvented, or our right or ability to manufacture our product was to be limited, our ability to continue to manufacture and market our product could be adversely affected. In addition to patents, we rely on trade secrets and proprietary know-how, which we seek to protect, in part, through confidentiality and proprietary information agreements. The other parties to these agreements may breach these provisions, and we may not have adequate remedies for any breach. Additionally, our trade secrets could otherwise become known to or be independently developed by competitors.

As of December 31, 2024, we have been issued, or have rights to, one U.S. patent (which expires on December 11, 2027). The patent we hold may be successfully challenged, invalidated or circumvented, or we may otherwise be unable to rely on this patent. These risks are also present for the process we use for manufacturing our product. In addition, our competitors, many of whom have substantial resources and have made substantial investments in competing technologies, may apply for and obtain patents that prevent, limit or interfere with our ability to make, use and sell our product, either in the United States or in international markets. The medical device industry has been characterized by extensive litigation regarding patents and other intellectual property rights. We may institute, become party to, or be threatened with, future adversarial proceedings or litigation regarding intellectual property rights with respect to our product and technology, including interference or derivation proceedings before the U.S. Patent and Trademark Office, or USPTO. Third parties may assert infringement claims against us based on existing patents or patents that may be granted in the future. If we are found to infringe a third party’s intellectual property rights, we could be required to obtain a license from such third party to continue developing and marketing our product and technology. However, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. We could be forced, including by court order, to cease commercializing the infringing technology or product. In addition, we could be found liable for monetary damages, including treble damages and attorneys’ fees if we are found to have willfully infringed a patent. A finding of infringement could prevent us from commercializing our product or force us to cease some of our business operations, which could materially harm our business. Claims that we have misappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our business. The defense and prosecution of intellectual property suits, USPTO proceedings and related legal and administrative

Table of Contents

proceedings are both costly and time consuming. Any litigation or interference proceedings involving us may require us to incur substantial legal and other fees and expenses and may require some of our employees to devote all or a substantial portion of their time to the proceedings.

We may need to license intellectual property from third parties, and such licenses may not be available or may not be available on commercially reasonable terms.

A third party may hold intellectual property, including patent rights that are important or necessary to the development of our vascular testing product or any future products. It may be necessary for us to use the patented or proprietary technology of a third party to commercialize our own technology or products, in which case we would be required to obtain a license from such third party. A license to such intellectual property may not be available or may not be available on commercially reasonable terms, which could have a material adverse effect on our business and financial condition.

We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual property, or claiming ownership of what we regard as our own intellectual property.

Although we try to ensure that we and our employees and independent contractors do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or that these employees or independent contractors have used or disclosed intellectual property in violation of the rights of others. These claims may cover a range of matters, such as challenges to our trademarks, as well as claims that our employees or independent contractors are using trade secrets or other proprietary information of any such employee’s former employer or independent contractors. Although we do not expect the resolution of the proceeding to have a material adverse effect on our business or financial condition, litigation to defend ourselves against claims can be both costly and time consuming, and divert management’s attention away from growing our business.

In addition, while it is our policy to require our employees and independent contractors who may be involved in the development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who in fact develops intellectual property that we regard as our own. Our and their assignment agreements may not be self-executing or may be breached, and we may be forced to bring claims against third parties, or defend claims they may bring against us, to determine the ownership of what we regard as our intellectual property.

If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in prosecuting or defending against such claims, litigation could result in substantial costs and be a distraction to management.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

In addition to seeking patents for some of our technology and product, we also rely on trade secrets, including unpatented know-how, technology and other proprietary information, to maintain our competitive position. We seek to protect these trade secrets, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to them, such as our employees, corporate collaborators, outside scientific collaborators, contract manufacturers, consultants, advisors and other third parties. We also generally enter into confidentiality and invention or patent assignment agreements with our employees and consultants. Despite these efforts, any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party infringed a patent or illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them, or those to whom they communicate it, from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor, our competitive position would be harmed.

Risks Related to Our Bitcoin Treasury Strategy and Holdings

WE ARE NOT REGISTERED AS AN INVESTMENT COMPANY UNDER THE INVESTMENT COMPANY ACT OF 1940 AND STOCKHOLDERS DO NOT HAVE THE PROTECTIONS ASSOCIATED WITH OWNERSHIP OF SHARES IN A REGISTERED INVESTMENT COMPANY NOR THE PROTECTIONS AFFORDED BY THE COMMODITIES EXCHANGE ACT.

Our bitcoin treasury strategy exposes us to various risks associated with bitcoin.

Bitcoin is a highly volatile asset.  Bitcoin is a highly volatile asset that has traded below $51,800 per bitcoin and above $106,000 per bitcoin on the Coinbase exchange in the 12 months preceding the date of this annual report on Form 10-K. The trading price of bitcoin significantly decreased during prior periods, and such declines may occur again in the future. Notwithstanding this volatility, we do not currently intend to hedge our bitcoin holdings and have not adopted a hedging strategy with respect to bitcoin. However, we may from time to time engage in hedging strategies as part of our treasury management operations if deemed appropriate.

Bitcoin does not pay interest or dividends.  Bitcoin does not pay interest or other returns and we can only generate cash from our bitcoin holdings if we sell our bitcoin or implement strategies to create income streams or otherwise generate cash by using our bitcoin holdings. Even if we pursue any such strategies, we may be unable to create income streams or otherwise generate cash from our bitcoin holdings, and any such strategies may subject us to additional risks.

Our bitcoin holdings may significantly impact our financial results and the market price of our common stock.  Our bitcoin holdings may significantly affect our financial results and if we continue to increase our overall holdings of bitcoin in the future, they will have an even greater impact on our financial results and the market price of our common stock. See “—Our historical financial statements do not reflect the potential variability in earnings that we may experience in the future relating to our bitcoin holding s ” below.

Our bitcoin treasury strategy has not been tested over an extended period of time or under different market conditions.  We only recently adopted our bitcoin treasury strategy and will need to continually examine the risks and rewards of this new strategy. This new strategy has not been tested over an extended period of time or under different market conditions. For example, although we believe bitcoin, due to its limited supply, has the potential to serve as a hedge against inflation in the long term, the short-term price of bitcoin declined in recent periods during which the inflation rate increased. Some investors and other market participants may disagree with our bitcoin treasury strategy or actions we undertake to implement it. If bitcoin prices were to decrease or our bitcoin treasury strategy otherwise proves unsuccessful, our financial condition, results of operations, and the market price of our common stock could be materially adversely affected.

We are subject to counterparty risks, including in particular risks relating to our custodians.  Although we have implemented various measures that are designed to mitigate our counterparty risks, including by storing substantially all of the bitcoin we own in custody accounts at U.S.-based, institutional-grade custodians and negotiating contractual arrangements intended to establish that our property interest in custodially-held bitcoin is not subject to claims of our custodians’ creditors, applicable insolvency law is not fully developed with respect to the holding of digital assets in custodial accounts. If our custodially-held bitcoin were nevertheless considered to be the property of our custodians’ estates in the event that any such custodians were to enter bankruptcy, receivership or similar insolvency proceedings, we could be treated as a general unsecured creditor of such custodians, inhibiting our ability to exercise ownership rights with respect to such bitcoin and this may ultimately result in the loss of the value related to some or all of such bitcoin. Even if we are able to prevent our bitcoin from being considered the property of a custodian’s bankruptcy estate as part of an insolvency proceeding, it is possible that we would still be delayed or may otherwise experience difficulty in accessing our bitcoin held by the affected custodian during the pendency of the insolvency proceedings. Any such outcome could have a material adverse effect on our financial condition and the market price of our common stock.

The broader digital assets industry is subject to counterparty risks, which could adversely impact the adoption rate, price, and use of bitcoin.  A series of recent high-profile bankruptcies, closures, liquidations, regulatory enforcement actions and other events relating to companies operating in the digital asset industry, including the filings for bankruptcy

Table of Contents

protection by Three Arrows Capital, Celsius Network, Voyager Digital, FTX Trading and Genesis Global Capital, the closure or liquidation of certain financial institutions that provided lending and other services to the digital assets industry, including Signature Bank and Silvergate Bank, SEC enforcement actions against Coinbase, Inc. and Binance Holdings Ltd., the placement of Prime Trust, LLC into receivership following a cease-and-desist order issued by Nevada’s Department of Business and Industry, and the filing and subsequent settlement of a civil fraud lawsuit by the New York Attorney General against Genesis Global Capital, its parent company Digital Currency Group, Inc., and former partner Gemini Trust Company, have highlighted the counterparty risks applicable to owning and transacting in digital assets. Although these bankruptcies, closures, liquidations and other events have not resulted in any loss or misappropriation of our bitcoin, nor have such events adversely impacted our access to our bitcoin, they have, in the short-term, likely negatively impacted the adoption rate and use of bitcoin. Additional bankruptcies, closures, liquidations, regulatory enforcement actions or other events involving participants in the digital assets industry in the future may further negatively impact the adoption rate, price, and use of bitcoin, limit the availability to us of financing collateralized by bitcoin, or create or expose additional counterparty risks.

Changes in our ownership of bitcoin could have accounting, regulatory and other impacts.  While we currently own or will own bitcoin directly, we may investigate other potential approaches to owning bitcoin, including indirect ownership (for example, through ownership interests in a fund that owns bitcoin). If we were to own all or a portion of our bitcoin in a different manner, the accounting treatment for our bitcoin, our ability to use our bitcoin as collateral for additional borrowings, and the regulatory requirements to which we are subject, may correspondingly change. For example, the volatile nature of bitcoin may force us to liquidate our holdings to use it as collateral, which could be negatively effected by any disruptions in the crypto market, and if liquidated, the value of the collateral would not reflect potential gains in market value of bitcoin, all of which could negatively affect our business and implementation of our bitcoin strategy.

Changes in the accounting treatment of our bitcoin holdings could have significant accounting impacts, including increasing the volatility of our results.  In December 2023, the FASB issued ASU 2023-08, which we early adopted as of January 1, 2024, and which requires us to measure in-scope crypto assets (including our bitcoin holdings) at fair value in our statement of financial position, and to recognize gains and losses from changes in the fair value of our bitcoin in net income each reporting period. ASU 2023-08 requires us to provide certain interim and annual disclosures with respect to our bitcoin holdings. Due in particular to the volatility in the price of bitcoin, we expect the adoption of ASU 2023-08 to have a material impact on our financial results in future periods, increase the volatility of our financial results, and affect the carrying value of our bitcoin on our balance sheet, and could have adverse tax consequences, which in turn could have a material adverse effect on our financial results and the market price of our common stock.

The broader digital assets industry, including the technology associated with digital assets, the rate of adoption and development of, and use cases for, digital assets, market perception of digital assets, and the legal, regulatory, and accounting treatment of digital assets are constantly developing and changing, and there may be additional risks in the future that are not possible to predict.

Bitcoin is a highly volatile asset, and fluctuations in the price of bitcoin are likely to influence our financial results and the market price of our common stock.

Bitcoin is a highly volatile asset, and fluctuations in the price of bitcoin are likely to influence our financial results and the market price of our common stock. Our financial results and the market price of our common stock would be adversely affected, and our business and financial condition would be negatively impacted, if the price of bitcoin decreased substantially (as it has in the past, such as during 2022), including as a result of:

decreased user and investor confidence in bitcoin, including due to the various factors described herein;

investment and trading activities such as (i) trading activities of highly active retail and institutional users, speculators, miners and investors, or of the U.S. or state governments, (ii) actual or expected significant dispositions of bitcoin by large holders, and (iii) actual or perceived manipulation of the spot or derivative markets for bitcoin or spot bitcoin ETPs;

Table of Contents

negative publicity, media or social media coverage, or sentiment due to events in or relating to, or perception of, bitcoin or the broader digital assets industry, for example, (i) public perception that bitcoin can be used as a vehicle to circumvent sanctions, including sanctions imposed on Russia or certain regions related to the ongoing conflict between Russia and Ukraine, or to fund criminal or terrorist activities, such as the purported use of digital assets by Hamas to fund its terrorist attack against Israel in October 2023; (ii) expected or pending civil, criminal, regulatory enforcement or other high profile actions against major participants in the bitcoin ecosystem, including the SEC’s enforcement actions against Coinbase, Inc. and Binance Holdings Ltd.; (iii) additional filings for bankruptcy protection or bankruptcy proceedings of major digital asset industry participants, such as the bankruptcy proceeding of FTX Trading and its affiliates; and (iv) the actual or perceived environmental impact of bitcoin and related activities, including environmental concerns raised by private individuals, governmental and non-governmental organizations, and other actors related to the energy resources consumed in the bitcoin mining process;

changes in consumer preferences and the perceived value or prospects of bitcoin;

competition from other digital assets that exhibit better speed, security, scalability, or energy efficiency, that feature other more favored characteristics, that are backed or held in large amounts by governments, including the U.S. government, or reserves of fiat currencies, or that represent ownership or security interests in physical assets;

a decrease in the price of other digital assets, including stablecoins, or the crash or unavailability of stablecoins that are used as a medium of exchange for bitcoin purchase and sale transactions, such as the crash of the stablecoin Terra USD in 2022, to the extent the decrease in the price of such other digital assets or the unavailability of such stablecoins may cause a decrease in the price of bitcoin or adversely affect investor confidence in digital assets generally;

the identification of Satoshi Nakamoto, the pseudonymous person or persons who developed bitcoin, or the transfer of substantial amounts of bitcoin from bitcoin wallets attributed to Mr. Nakamoto or other “whales” that hold significant amounts of bitcoin;

disruptions, failures, unavailability, or interruptions in service of trading venues for bitcoin, such as, for example, the announcement by the digital asset exchange FTX Trading that it would freeze withdrawals and transfers from its accounts and subsequent filing for bankruptcy protection and the recent SEC enforcement action brought against Binance Holdings Ltd., which initially sought to freeze all of its assets during the pendency of the enforcement action;

the filing for bankruptcy protection by, liquidation of, or market concerns about the financial viability of digital asset custodians, trading venues, lending platforms, investment funds, or other digital asset industry participants, such as the filing for bankruptcy protection by digital asset trading venues FTX Trading and BlockFi and digital asset lending platforms Celsius Network and Voyager Digital Holdings in 2022, the ordered liquidation of the digital asset investment fund Three Arrows Capital in 2022, the announced liquidation of Silvergate Bank in 2023, the government-mandated closure and sale of Signature Bank in 2023, the placement of Prime Trust, LLC into receivership following a cease-and-desist order issued by the Nevada Department of Business and Industry in 2023, and the exit of Binance Holdings Ltd. from the U.S. market as part of its settlement with the Department of Justice and other federal regulatory agencies;

regulatory, legislative, enforcement and judicial actions that adversely affect the price, ownership, transferability, trading volumes, legality or public perception of bitcoin, or that adversely affect the operations of or otherwise prevent digital asset custodians, trading venues, lending platforms or other digital assets industry participants from operating in a manner that allows them to continue to deliver services to the digital assets industry;

Table of Contents

further reductions in mining rewards of bitcoin, including block reward halving events, which are events that occur after a specific period of time that reduce the block reward earned by “miners” who validate bitcoin transactions, or increases in the costs associated with bitcoin mining, including increases in electricity costs and hardware and software used in mining, that may cause a decline in support for the Bitcoin network;

transaction congestion and fees associated with processing transactions on the bitcoin network;

macroeconomic changes, such as changes in the level of interest rates and inflation, fiscal and monetary policies of governments, trade restrictions, and fiat currency devaluations;

developments in mathematics or technology, including in digital computing, algebraic geometry and quantum computing, that could result in the cryptography used by the bitcoin blockchain becoming insecure or ineffective; and

changes in national and international economic and political conditions, including, without limitation, the adverse impact attributable to the economic and political instability caused by the current conflict between Russia and Ukraine and the economic sanctions adopted in response to the conflict, and the potential broadening of the Israel-Hamas conflict to other countries in the Middle East, as well as expectations regarding changes to the regulatory environment, including for the U.S. digital asset industry.

Bitcoin and other digital assets are novel assets, and are subject to significant legal, commercial, regulatory and technical uncertainty.

Bitcoin and other digital assets are relatively novel and are subject to significant uncertainty, which could adversely impact their price. The application of state and federal securities laws and other laws and regulations to digital assets is unclear in certain respects, and it is possible that regulators in the United States or foreign countries may interpret or apply existing laws and regulations in a manner that adversely affects the price of bitcoin.

The U.S. federal government, states, regulatory agencies, and foreign countries may also enact new laws and regulations, or pursue regulatory, legislative, enforcement or judicial actions, that could materially impact the price of bitcoin or the ability of individuals or institutions such as us to own or transfer bitcoin. For example, the U.S. executive branch and SEC, among others in the United States and abroad, have been active in recent years, and laws including the European Union’s Markets in Crypto Assets Regulation and the U.K.’s Financial Services and Markets Act 2023 became law. It is not possible to predict whether, or when, any of these developments will lead to Congress granting additional authorities to the SEC or other regulators, or whether, or when, any other federal, state or foreign legislative bodies will take any similar actions. It is also not possible to predict the nature of any such additional authorities, how additional legislation or regulatory oversight might impact the ability of digital asset markets to function or the willingness of financial and other institutions to continue to provide services to the digital assets industry, nor how any new regulations or changes to existing regulations might impact the value of digital assets generally and bitcoin specifically. The consequences of increased or different regulation of digital assets and digital asset activities could adversely affect the market price of bitcoin and in turn adversely affect the market price of our common stock.

Moreover, the risks of engaging in a bitcoin treasury strategy are relatively novel and have created, and could continue to create, complications due to the lack of experience that third parties have with companies engaging in such a strategy, such as increased costs of director and officer liability insurance or the potential inability to obtain such coverage on acceptable terms in the future.

The growth of the digital assets industry in general, and the use and acceptance of bitcoin in particular, may also impact the price of bitcoin and is subject to a high degree of uncertainty. The pace of worldwide growth in the adoption and use of bitcoin may depend, for instance, on public familiarity with digital assets, ease of buying, accessing or gaining exposure to bitcoin, institutional demand for bitcoin as an investment asset, the participation of traditional financial institutions in the digital assets industry, consumer demand for bitcoin as a means of payment, and the availability and popularity of alternatives to bitcoin. Even if growth in bitcoin adoption occurs in the near or medium-term, there is no assurance that bitcoin usage will continue to grow over the long-term.

Because bitcoin has no physical existence beyond the record of transactions on the bitcoin blockchain, a variety of technical factors related to the bitcoin blockchain could also impact the price of bitcoin. For example, malicious attacks by miners, inadequate mining fees to incentivize validating of bitcoin transactions, hard “forks” of the bitcoin blockchain into multiple blockchains, and advances in digital computing, algebraic geometry, and quantum computing could undercut the integrity of the bitcoin blockchain and negatively affect the price of bitcoin. The liquidity of bitcoin may also be reduced and damage to the public perception of bitcoin may occur, if financial institutions were to deny or limit banking services to businesses that hold bitcoin, provide bitcoin-related services or accept bitcoin as payment, which could also decrease the price of bitcoin. Similarly, the open-source nature of the bitcoin blockchain means the contributors and developers of the bitcoin blockchain are generally not directly compensated for their contributions in maintaining and developing the blockchain, and any failure to properly monitor and upgrade the bitcoin blockchain could adversely affect the bitcoin blockchain and negatively affect the price of bitcoin.

Recent actions by U.S. banking regulators have reduced the ability of bitcoin-related services providers to gain access to banking services and liquidity of bitcoin may also be impacted to the extent that changes in applicable laws and regulatory requirements negatively impact the ability of exchanges and trading venues to provide services for bitcoin and other digital assets.

In addition, while the current administration has expressed support regarding the development and use of digital assets as the industry has anticipated, the specific regulatory frameworks are still to be developed. Expectations around U.S. digital asset policy, including potential sentiments that the U.S. government is not moving quickly enough or not meeting policy expectations, may adversely affect the price of bitcoin.

Our historical financial statements do not reflect the potential variability in earnings that we may experience in the future relating to our bitcoin holdings.

Our historical financial statements do not reflect the potential variability in earnings that we may experience in the future from holding or selling significant amounts of bitcoin.

The price of bitcoin has historically been subject to dramatic price fluctuations and is highly volatile. We determine the fair value of our bitcoin based on quoted (unadjusted) prices on the Coinbase exchange, and following our early adoption of ASU 2023-08 we are required to measure our bitcoin holdings at fair value in our statement of financial position, and to recognize gains and losses from changes in the fair value of our bitcoin in net income each reporting period, which may create significant volatility in our reported earnings and decrease the carrying value of our digital assets, which in turn could have a material adverse effect on the market price of our common stock. Conversely, any sale of bitcoins at prices above our carrying value for such assets creates a gain for financial reporting purposes even if we would otherwise incur an economic or tax loss with respect to such transaction, which also may result in significant volatility in our reported earnings.

Due in particular to the volatility in the price of bitcoin, we expect our early adoption of ASU 2023-08 to increase the volatility of our financial results and it could significantly affect the carrying value of our bitcoin on our balance sheet. As of December 31, 2024, we held 2,298 bitcoins, which we acquired for $189.7 million during the year, inclusive of fees and expenses, with an aggregate value of $214.6 million due to an adjustment in their fair value of $24.9 million, and $9.0 million in cash, cash equivalents and restricted cash, compared to carrying no digital assets and having $57.3 million in cash, cash equivalents and short-term investments as of December 31, 2023.

Because we intend to purchase additional bitcoin in future periods and increase our overall holdings of bitcoin, we expect that the proportion of our total assets represented by our bitcoin holdings will increase in the future. As a result, and in particular with respect to the quarterly periods and full fiscal year with respect to which ASU 2023-08 applies, and for all future periods, volatility in our earnings may be significantly more than what we experienced in prior periods.

The availability of spot bitcoin ETPs may adversely affect the market price of our common stock.

Although bitcoin and other digital assets have experienced a surge of investor attention since bitcoin was invented in 2008, until recently investors in the United States had limited means to gain direct exposure to bitcoin through traditional investment channels, and instead generally were only able to hold bitcoin through “hosted” wallets provided by digital asset service providers or through “unhosted” wallets that expose the investor to risks associated with loss or hacking of their private keys. Given the relative novelty of digital assets, general lack of familiarity with the processes needed to hold bitcoin directly, as well as the potential reluctance of financial planners and advisers to recommend direct bitcoin holdings to their retail customers because of the manner in which such holdings are custodied, some investors have sought exposure to bitcoin through investment vehicles that hold bitcoin and issue shares representing fractional undivided interests in their underlying bitcoin holdings. These vehicles, which were previously offered only to “accredited investors” on a private placement basis, have in the past traded at substantial premiums to net asset value, or NAV, possibly due to the relative scarcity of traditional investment vehicles providing investment exposure to bitcoin.

On January 10, 2024, the SEC approved the listing and trading of spot bitcoin ETPs, the shares of which can be sold in public offerings and are traded on U.S. national securities exchanges. The approved ETPs commenced trading directly to the public on January 11, 2024, with a trading volume of approximately $4.6 billion on the first trading day. To the extent investors view our common stock as providing exposure to bitcoin, it is possible that the value of our common stock may also have included a premium over the value of our bitcoin due to the prior scarcity of traditional investment vehicles providing investment exposure to bitcoin, and that the value declined due to investors now having a greater range of options to gain exposure to bitcoin and investors choosing to gain such exposure through ETPs rather than our common stock.

Although we are an operating company providing technology solutions to improve the clinical effectiveness and efficiency of healthcare providers, and we believe we offer a different value proposition than a passive bitcoin investment vehicle such as a spot bitcoin ETP, investors may nevertheless view our common stock as an alternative to an investment in an ETP, and choose to purchase shares of a spot bitcoin ETP instead of our common stock. They may do so for a variety of reasons, including if they believe that ETPs offer a “pure play” exposure to bitcoin that is generally not subject to federal income tax at the entity level as we are, or the other risk factors applicable to an operating business, such as ours. Additionally, unlike spot bitcoin ETPs, we (i) do not seek for our shares of common stock to track the value of the underlying bitcoin we hold before payment of expenses and liabilities, (ii) do not benefit from various exemptions and relief under the Securities Exchange Act of 1934, as amended, or the Exchange Act, including Regulation M, and other securities laws, which enable spot bitcoin ETPs to continuously align the value of their shares to the price of the underlying bitcoin they hold through share creation and redemption, (iii) are a Delaware corporation rather than a statutory trust, and do not operate pursuant to a trust agreement that would require us to pursue one or more stated investment objectives, and (iv) are not required to provide daily transparency as to our bitcoin holdings or our daily NAV. Furthermore, recommendations by broker-dealers to buy, hold, or sell complex products and non-traditional ETPs, or an investment strategy involving such products, may be subject to additional or heightened scrutiny that would not be applicable to broker-dealers making recommendations with respect to our common stock. Based on how we are viewed in the market relative to ETPs, and other vehicles that offer economic exposure to bitcoin, such as bitcoin futures ETFs and leveraged bitcoin futures ETFs, any premium or discount in our common stock relative to the value of our bitcoin holdings may increase or decrease in different market conditions.

As a result of the foregoing factors, availability of spot bitcoin ETPs on U.S. national securities exchanges could have a material adverse effect on the market price of our common stock.

Our bitcoin treasury strategy subjects us to enhanced regulatory oversight.

As noted elsewhere in these Risk Factors, several spot bitcoin ETPs have received approval from the SEC to list their shares on a U.S. national securities exchange with continuous share creation and redemption at NAV. Even though we are not, and do not function in the manner of, a spot bitcoin ETP, it is possible that we nevertheless could face regulatory scrutiny from the SEC or other federal or state agencies due to our bitcoin holdings.

In addition, there has been increasing focus on the extent to which digital assets can be used to launder the proceeds of illegal activities, fund criminal or terrorist activities, or circumvent sanctions regimes, including those sanctions imposed in response to the ongoing conflict between Russia and Ukraine. While we have implemented and maintain policies and procedures reasonably designed to promote compliance with applicable anti-money laundering and sanctions laws and regulations and take care to only acquire our bitcoin through entities subject to anti-money laundering regulation and related compliance rules in the United States, if we are found to have purchased any of our bitcoin from bad actors that have used bitcoin to launder money or persons subject to sanctions, we may be subject to regulatory proceedings and any further transactions or dealings in bitcoin by us may be restricted or prohibited.

We may consider issuing debt or other financial instruments that may be collateralized by our bitcoin holdings. We may also consider pursuing strategies to create income streams or otherwise generate funds using our bitcoin holdings. These types of bitcoin-related transactions are the subject of enhanced regulatory oversight. These and any other bitcoin-related transactions we may enter into, beyond simply acquiring and holding bitcoin, may subject us to additional regulatory compliance requirements and scrutiny, including under federal and state money services regulations, money transmitter licensing requirements and various commodity and securities laws and regulations.

Additional laws, guidance and policies may be issued by domestic and foreign regulators following the filing for Chapter 11 bankruptcy protection by FTX Trading, one of the world’s largest cryptocurrency exchanges, in November 2022. U.S. and foreign regulators have also increased enforcement activity thereafter, and regulatory requirements continue to evolve in response to FTX Trading’s collapse as well as changes in government policies regarding cryptocurrencies. Changes in the regulatory environment, including changing interpretations and the implementation of new or varying regulatory requirements by the government or any new legislation affecting bitcoin, as well as enforcement actions involving or impacting our trading venues, counterparties and custodians, may impose significant costs or significantly limit our ability to hold and transact in bitcoin.

In addition, private actors that are wary of bitcoin or the regulatory concerns associated with bitcoin may in the future take further actions that may have an adverse effect on our business or the market price of our common stock.

Due to the currently unregulated nature and lack of transparency surrounding the operations of many bitcoin trading venues, bitcoin trading venues may experience greater fraud, security failures or regulatory or operational problems than trading venues for more established asset classes, which may result in a loss of confidence in bitcoin trading venues and adversely affect the value of our bitcoin.

Bitcoin trading venues are relatively new and, in many cases, currently unregulated. Even if regulated, such venues may not be complying with such regulations. Furthermore, there are many bitcoin trading venues that do not provide the public with significant information regarding their ownership structure, management teams, corporate practices and regulatory compliance. As a result, the marketplace may lose confidence in bitcoin trading venues, including prominent exchanges that handle a significant volume of bitcoin trading and/or are subject to regulatory oversight, in the event one or more bitcoin trading venues cease or pause for a prolonged period the trading of bitcoin or other digital assets, or experience fraud, significant volumes of withdrawal, security failures or operational problems.

In 2019 there were reports claiming that 80-95% of bitcoin trading volume on trading venues was false or non-economic in nature, with specific focus on currently unregulated exchanges located outside of the United States. The SEC also alleged as part of its June 2023, complaint that Binance Holdings Ltd. committed strategic and targeted “wash trading” through its affiliates to artificially inflate the volume of certain digital assets traded on its exchange. Such reports and allegations may indicate that the bitcoin market is significantly smaller than expected and that the United States makes up a significantly larger percentage of the bitcoin market than is commonly understood. Any actual or perceived false trading in the bitcoin market, and any other fraudulent or manipulative acts and practices, could adversely affect the value of our bitcoin. Negative perception, a lack of stability in the broader bitcoin markets and the closure, temporary shutdown or operational disruption of bitcoin trading venues, lending institutions, institutional investors, institutional miners, custodians, or other major participants in the bitcoin ecosystem, due to fraud, business failure, cybersecurity events, government-mandated regulation, bankruptcy, or for any other reason, may result in a decline in confidence in bitcoin and the broader bitcoin ecosystem and greater volatility in the price of bitcoin. For example, in 2022, each of Celsius Network, Voyager Digital, Three Arrows Capital, FTX Trading, and BlockFi filed for

Table of Contents

bankruptcy, following which the market prices of bitcoin and other digital assets significantly declined. In addition, in June 2023, the SEC announced enforcement actions against Coinbase, Inc., and Binance Holdings Ltd., two providers of large trading venues for digital assets, which similarly was followed by a decrease in the market price of bitcoin and other digital assets. These were followed in November 2023, by an SEC enforcement action against Kraken, another large trading venue for digital assets. As the price of our common stock is affected by the value of our bitcoin holdings, the failure of a major participant in the bitcoin ecosystem could have a material adverse effect on the market price of our common stock.

The concentration of our bitcoin holdings enhances the risks inherent in our bitcoin treasury strategy.

As of December 31, 2024, we held an aggregate 2,298 bitcoins, which we acquired for $189.7 million, inclusive of fees and expenses, and we intend to purchase additional bitcoin and increase our overall holdings of bitcoin in the future. The concentration of our bitcoin holdings limits the risk mitigation that we could take advantage of by purchasing a more diversified portfolio of treasury assets, and the absence of diversification enhances the risks inherent in our bitcoin acquisition strategy. Any future significant declines in the price of bitcoin would have a more pronounced impact on our financial condition than if we used our cash to purchase a more diverse portfolio of assets.

The emergence or growth of other digital assets, including those with significant private or public sector backing, could have a negative impact on the price of bitcoin and adversely affect our financial condition and results of operations.

As a result of our bitcoin treasury strategy, the majority of our cash is now concentrated in our bitcoin holdings. Accordingly, the emergence or growth of digital assets other than bitcoin may have a material adverse effect on our financial condition. While bitcoin is the largest digital asset by market capitalization as of the date of this annual report on Form 10-K, there are numerous alternative digital assets and many entities, including the U.S. government, consortiums and financial institutions, are researching and investing resources into private or permissioned blockchain platforms or digital assets that do not use proof-of-work mining like the bitcoin network. For example, in late 2022, the Ethereum network transitioned to a “proof-of-stake” mechanism for validating transactions that requires significantly less computing power than proof-of-work mining. The Ethereum network has completed another major upgrade since then and may undertake additional upgrades in the future. If the mechanisms for validating transactions in Ethereum and other alternative digital assets are perceived as superior to proof-of-work mining, those digital assets could gain market share relative to bitcoin.

Other alternative digital assets that compete with bitcoin in certain ways include “stablecoins,” which are designed to maintain a constant price because of, for instance, their issuers’ promise to hold high-quality liquid assets (such as U.S. dollar deposits and short-term U.S. treasury securities) equal to the total value of stablecoins in circulation. Stablecoins have grown rapidly as an alternative to bitcoin and other digital assets as a medium of exchange and store of value, particularly on digital asset trading platforms. As of the date of this annual report on Form 10-K, two of the seven largest digital assets by market capitalization are U.S. dollar-backed stablecoins.

Additionally, central banks in some countries have started to introduce digital forms of legal tender. For example, China’s CBDC project was made available to consumers in January 2022, and governments including the European Union and Israel have been discussing the potential creation of new CBDCs. Whether or not they incorporate blockchain or similar technology, CBDCs, as legal tender in the issuing jurisdiction, could also compete with, or replace, bitcoin and other digital assets as a medium of exchange or store of value. As a result, the emergence or growth of these or other digital assets could cause the market price of bitcoin to decrease, which could have a material adverse effect on our financial condition, and operating results.

Our bitcoin holdings are less liquid than our existing cash and cash equivalents and may not be able to serve as a source of liquidity for us to the same extent as cash and cash equivalents.

Historically, the bitcoin markets have been characterized by significant volatility in price, limited liquidity and trading volumes compared to sovereign currencies markets, relative anonymity, a developing regulatory landscape, potential susceptibility to market abuse and manipulation, compliance and internal control failures at exchanges, and

Table of Contents

various other risks inherent in its entirely electronic, virtual form and decentralized network. During times of market instability, we may not be able to sell our bitcoin at favorable prices or at all. For example, a number of bitcoin trading venues temporarily halted deposits and withdrawals in 2022. As a result, our bitcoin holdings may not be able to serve as a source of liquidity for us to the same extent as cash and cash equivalents. Further, bitcoin we hold with our custodians and transact with our trade execution partners does not enjoy the same protections as are available to cash or securities deposited with or transacted by institutions subject to regulation by the Federal Deposit Insurance Corporation or the Securities Investor Protection Corporation. Additionally, we may be unable to enter into term loans or other capital raising transactions collateralized by our unencumbered bitcoin or otherwise generate funds using our bitcoin holdings, including in particular during times of market instability or when the price of bitcoin has declined significantly. If we are unable to sell our bitcoin, enter into additional capital raising transactions using bitcoin as collateral, or otherwise generate funds using our bitcoin holdings, or if we are forced to sell our bitcoin at a significant loss, in order to meet our working capital requirements, our business and financial condition could be negatively impacted.

If we or our third-party service providers experience a security breach or cyberattack and unauthorized parties obtain access to our bitcoin, or if our private keys are lost or destroyed, or other similar circumstances or events occur, we may lose some or all of our bitcoin and our financial condition and results of operations could be materially adversely affected.

Substantially all of the bitcoin we own is held in custody accounts at U.S.-based institutional-grade digital asset custodians. Security breaches and cyberattacks are of particular concern with respect to our bitcoin. Bitcoin and other blockchain-based cryptocurrencies and the entities that provide services to participants in the bitcoin ecosystem have been, and may in the future be, subject to security breaches, cyberattacks, or other malicious activities. For example, in October 2021 it was reported that hackers exploited a flaw in the account recovery process and stole from the accounts of at least 6,000 customers of the Coinbase exchange, although the flaw was subsequently fixed and Coinbase reimbursed affected customers. Similarly, in November 2022, hackers exploited weaknesses in the security architecture of the FTX Trading digital asset exchange and reportedly stole over $400 million in digital assets from customers. A successful security breach or cyberattack could result in:

a partial or total loss of our bitcoin in a manner that may not be covered by insurance or the liability provisions of the custody agreements with the custodians who hold our bitcoin;

harm to our reputation and brand;

improper disclosure of data and violations of applicable data privacy and other laws; or

significant regulatory scrutiny, investigations, fines, penalties, and other legal, regulatory, contractual and financial exposure.

Further, any actual or perceived data security breach or cybersecurity attack directed at other companies with digital assets or companies that operate digital asset networks, regardless of whether we are directly impacted, could lead to a general loss of confidence in the broader bitcoin blockchain ecosystem or in the use of the bitcoin network to conduct financial transactions, which could negatively impact us.

Attacks upon systems across a variety of industries, including industries related to bitcoin, are increasing in frequency, persistence, and sophistication, and, in many cases, are being conducted by sophisticated, well-funded and organized groups and individuals, including state actors. The techniques used to obtain unauthorized, improper or illegal access to systems and information (including personal data and digital assets), disable or degrade services, or sabotage systems are constantly evolving, may be difficult to detect quickly, and often are not recognized or detected until after they have been launched against a target. These attacks may occur on our systems or those of our third-party service providers or partners. We may experience breaches of our security measures due to human error, malfeasance, insider threats, system errors or vulnerabilities or other irregularities. In particular, we expect that unauthorized parties will attempt to gain access to our systems and facilities, as well as those of our partners and third-party service providers, through various means, such as hacking, social engineering, phishing and fraud. Threats can come from a variety of sources, including criminal hackers, hacktivists, state-sponsored intrusions, industrial espionage, and insiders. In addition, certain types of attacks could harm us even if our systems are left undisturbed. For example, certain threats are designed to remain dormant or undetectable, sometimes for extended periods of time, or until launched against a target

Table of Contents

and we may not be able to implement adequate preventative measures. Further, there has been an increase in such activities due to the increase in work-from-home arrangements. The risk of cyberattacks could also be increased by cyberwarfare in connection with the ongoing Russia-Ukraine and Israel-Hamas conflicts, or other future conflicts, including potential proliferation of malware into systems unrelated to such conflicts. Any future breach of our operations or those of others in the bitcoin industry, including third-party services on which we rely, could materially and adversely affect our financial condition and results of operations.

We face risks relating to the custody of our bitcoin, including the loss or destruction of private keys required to access our bitcoin and cyberattacks or other data loss relating to our bitcoin.

We hold our bitcoin with regulated custodians that have duties to safeguard our private keys. Our custodial services contracts do not restrict our ability to reallocate our bitcoin among our custodians, and our bitcoin holdings may be concentrated with a single custodian from time to time. In light of the significant amount of bitcoin we hold, we continually seek to engage additional custodians to achieve a greater degree of diversification in the custody of our bitcoin as the extent of potential risk of loss is dependent, in part, on the degree of diversification. If there is a decrease in the availability of digital asset custodians that we believe can safely custody our bitcoin, for example, due to regulatory developments or enforcement actions that cause custodians to discontinue or limit their services in the United States, we may need to enter into agreements that are less favorable than our current agreements or take other measures to custody our bitcoin, and our ability to seek a greater degree of diversification in the use of custodial services would be materially adversely affected. In addition, holding our bitcoin with regulated custodians could affect the availability of receiving digital assets that may result from “forks” of the bitcoin blockchain if our custodians are unable to support or otherwise provide us with such digital assets, thereby reducing the amount of digital assets we may hold as a result. While our custodians carry insurance policies to cover losses for commercial crimes, cyber and cold storage, the policy limits vary per provider and would be shared among all of their customers, and subject to various limitations and exclusions (such as if a loss arises due to our failure to protect our login credentials and devices). The insurance that covers losses of our bitcoin holdings may cover only a small fraction of the value of the entirety of our bitcoin holdings, and there can be no guarantee that such insurance will be maintained as part of the custodial services we have or that such coverage will cover losses with respect to our bitcoin. Moreover, our use of custodians exposes us to the risk that the bitcoin our custodians hold on our behalf could be subject to insolvency proceedings and we could be treated as a general unsecured creditor of the custodian, inhibiting our ability to exercise ownership rights with respect to such bitcoin. Any loss associated with such insolvency proceedings is unlikely to be covered by any insurance coverage we maintain related to our bitcoin.

Bitcoin is controllable only by the possessor of both the unique public key and private key(s) relating to the local or online digital wallet in which the bitcoin is held. While the bitcoin blockchain ledger requires a public key relating to a digital wallet to be published when used in a transaction, private keys must be safeguarded and kept private in order to prevent a third party from accessing the bitcoin held in such wallet. To the extent the private key(s) for a digital wallet are lost, destroyed, or otherwise compromised and no backup of the private key(s) is accessible, neither we nor our custodians will be able to access the bitcoin held in the related digital wallet. Furthermore, we cannot provide assurance that our digital wallets, nor the digital wallets of our custodians held on our behalf, will not be compromised as a result of a cyberattack. The bitcoin and blockchain ledger, as well as other digital assets and blockchain technologies, have been, and may in the future be, subject to security breaches, cyberattacks, or other malicious activities.

Regulatory change reclassifying bitcoin as a security could lead to our classification as an “investment company” under the 1940 Act and could adversely affect the market price of bitcoin and the market price of our common stock.

Under Sections 3(a)(1)(A) and (C) of the 1940 Act, a company generally will be deemed to be an “investment company” for purposes of the 1940 Act if (1) it is, or holds itself out as being, engaged primarily, or proposes to engage primarily, in the business of investing, reinvesting or trading in securities or (2) it engages, or proposes to engage, in the business of investing, reinvesting, owning, holding or trading in securities and it owns or proposes to acquire investment securities having a value exceeding 40% of the value of its total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis. We do not believe that we are an “investment company,” as such term is defined in the 1940 Act, and are not registered as an “investment company” under the 1940 Act as of the date of this annual report on Form 10-K.

While senior SEC officials have stated their view that bitcoin is not a “security” for purposes of the federal securities laws, a contrary determination by the SEC could lead to our classification as an “investment company” under the 1940 Act, if the portion of our assets consists of investments in bitcoins exceeds 40% safe harbor limits prescribed in the 1940 Act, which would subject us to significant additional regulatory controls that could have a material adverse effect on our business and operations and may also require us to change the manner in which we conduct our business.

We monitor our assets and income for compliance under the 1940 Act and seek to conduct our business activities in a manner such that we do not fall within its definitions of “investment company” or that we qualify under one of the exemptions or exclusions provided by the 1940 Act and corresponding SEC regulations. If bitcoin is determined to constitute a security for purposes of the federal securities laws, we would take steps to reduce the percentage of bitcoins that constitute investment assets under the 1940 Act. These steps may include, among others, selling bitcoins that we might otherwise hold for the long term and deploying our cash in non-investment assets, and we may be forced to sell our bitcoins at unattractive prices. We may also seek to acquire additional non-investment assets to maintain compliance with the 1940 Act, and we may need to incur debt, issue additional equity or enter into other financing arrangements that are not otherwise attractive to our business. Any of these actions could have a material adverse effect on our results of operations and financial condition. Moreover, we can make no assurance that we would successfully be able to take the necessary steps to avoid being deemed to be an investment company in accordance with the safe harbor. If we were unsuccessful, and if bitcoin is determined to constitute a security for purposes of the federal securities laws, then we would have to register as an investment company, and the additional regulatory restrictions imposed by 1940 Act could adversely affect the market price of bitcoin and in turn adversely affect the market price of our common stock.

We may be subject to regulatory developments related to crypto assets and crypto asset markets, which could adversely affect our business, financial condition, and results of operations.

As bitcoin and other digital assets are relatively novel and the application of state and federal securities laws and other laws and regulations to digital assets is unclear in certain respects, it is possible that regulators in the United States or foreign countries may interpret or apply existing laws and regulations in a manner that adversely affects the price of bitcoin. The U.S. federal government, states, regulatory agencies, and foreign countries may also enact new laws and regulations, or pursue regulatory, legislative, enforcement or judicial actions, that could materially impact the price of bitcoin or the ability of individuals or institutions such as us to own or transfer bitcoin. For examples, see “Bitcoin and other digital assets are novel assets, and are subject to significant legal, commercial, regulatory and technical uncertainty” elsewhere in these Risk Factors.

If bitcoin is determined to constitute a security for purposes of the federal securities laws, the additional regulatory restrictions imposed by such a determination could adversely affect the market price of bitcoin and in turn adversely affect the market price of our common stock. See “Regulatory change reclassifying bitcoin as a security could lead to our classification as an “investment company” under the 1940 Act, and could adversely affect the market price of bitcoin and the market price of our common stock” elsewhere in these Risk Factors. Moreover, the risks of us engaging in a bitcoin treasury strategy have created, and could continue to create, complications due to the lack of experience that third parties have with companies engaging in such a strategy, such as increased costs of director and officer liability insurance or the potential inability to obtain such coverage on acceptable terms in the future.

Our bitcoin treasury strategy exposes us to risk of non-performance by counterparties.

Our bitcoin treasury strategy exposes us to the risk of non-performance by counterparties, whether contractual or otherwise. Risk of non-performance includes inability or refusal of a counterparty to perform because of a deterioration in the counterparty’s financial condition and liquidity or for any other reason. For example, our execution partners, custodians, or other counterparties might fail to perform in accordance with the terms of our agreements with them, which could result in a loss of bitcoin, a loss of the opportunity to generate funds, or other losses.

Our primary counterparty risk with respect to our bitcoin is custodian performance obligations under the various custody arrangements we have entered into. A series of recent high-profile bankruptcies, closures, liquidations, regulatory enforcement actions and other events relating to companies operating in the digital asset industry, the closure

Table of Contents

or liquidation of certain financial institutions that provided lending and other services to the digital assets industry, SEC enforcement actions against other providers, or placement into receivership or civil fraud lawsuit against digital asset industry participants have highlighted the perceived and actual counterparty risk applicable to digital asset ownership and trading. Although these bankruptcies, closures and liquidations have not adversely impacted our bitcoin (which was only recently acquired), legal precedent created in these bankruptcy and other proceedings may increase the risk of future rulings adverse to our interests in the event one or more of our custodians becomes a debtor in a bankruptcy case or is the subject of other liquidation, insolvency or similar proceedings.

While our custodians are subject to regulatory regimes intended to protect customers in the event of a custodial bankruptcy, receivership or similar insolvency proceeding, no assurance can be provided that our custodially-held bitcoin will not become part of the custodian’s insolvency estate if one or more of our custodians enters bankruptcy, receivership or similar insolvency proceedings. Additionally, if we pursue any strategies to create income streams or otherwise generate funds using our bitcoin holdings, we would become subject to additional counterparty risks. Although no such strategies are contemplated at this time, we will need to carefully evaluate market conditions, including price volatility as well as service provider terms and market reputations and performance, among others, prior to implementing any such strategy, all of which could effect our ability to successfully implement and execute on any such future strategy. These risks, along with any significant non-performance by counterparties, including in particular the custodians with which we custody substantially all of our bitcoin, could have a material adverse effect on our business, prospects, financial condition, and operating results.

Our custodially-held bitcoin may become part of the custodian’s insolvency estate if one or more of our custodians enters bankruptcy, receivership or similar insolvency proceedings.

If our custodially-held bitcoin are considered to be the property of our custodians’ estates in the event that any such custodians were to enter bankruptcy, receivership or similar insolvency proceedings, we could be treated as a general unsecured creditor of such custodians, inhibiting our ability to exercise ownership rights with respect to such bitcoin and this may ultimately result in the loss of the value related to some or all of such bitcoin. A series of recent high-profile bankruptcies, closures, liquidations, regulatory enforcement actions and other events relating to companies operating in the digital asset industry, including the filings for bankruptcy protection by Three Arrows Capital, Celsius Network, Voyager Digital, FTX Trading and Genesis Global Capital, the closure or liquidation of certain financial institutions that provided lending and other services to the digital assets industry, including Signature Bank and Silvergate Bank, SEC enforcement actions against Coinbase, Inc. and Binance Holdings Ltd., the placement of Prime Trust, LLC into receivership following a cease-and-desist order issued by Nevada’s Department of Business and Industry, and the filing and subsequent settlement of a civil fraud lawsuit by the New York Attorney General against Genesis Global Capital, its parent company Digital Currency Group, Inc., and former partner Gemini Trust Company, have highlighted the counterparty risks applicable to owning and transacting in digital assets. Although these bankruptcies, closures, liquidations and other events have not resulted in any loss or misappropriation of our bitcoin, nor have such events adversely impacted our access to our bitcoin, they have, in the short-term, likely negatively impacted the adoption rate and use of bitcoin. Additional bankruptcies, closures, liquidations, regulatory enforcement actions or other events involving participants in the digital assets industry in the future may further negatively impact the adoption rate, price, and use of bitcoin, limit the availability to us of financing collateralized by bitcoin, or create or expose additional counterparty risks. Any loss associated with such insolvency proceedings is unlikely to be covered by any insurance coverage we maintain related to our bitcoin. Even if we are able to prevent our bitcoin from being considered the property of a custodian’s bankruptcy estate as part of an insolvency proceeding, it is possible that we would still be delayed or may otherwise experience difficulty in accessing our bitcoin held by the affected custodian during the pendency of the insolvency proceedings. Any such outcome could have a material adverse effect on our financial condition and the market price of our common stock.

A temporary or permanent blockchain “fork” to bitcoin or other crypto assets could adversely affect our business.

Blockchain protocols, including bitcoin, are open source. Any user can download the software, modify it, and then propose that bitcoin or other blockchain protocols users and miners adopt the modification. When a modification is introduced and a substantial majority of users and miners consent to the modification, the change is implemented and the bitcoin or other blockchain protocol networks, as applicable, remain uninterrupted. However, if less than a substantial majority of users and miners consent to the proposed modification, and the modification is not compatible with the software prior to its modification, the consequence would be what is known as a “fork”,  i.e. , “split” of the impacted blockchain protocol network and respective blockchain, with one prong running the pre-modified software and the other running the modified software. The effect of such a fork would be the existence of two parallel versions of the bitcoin or other blockchain protocol network, as applicable, running simultaneously, but with each split network’s crypto asset lacking interchangeability. A “hard fork” – where there is disagreement among the users about the rules of the network – can have a significant negative impact on value of the crypto asset.

The bitcoin has been subject to “forks” that resulted in the creation of new networks, including bitcoin cash ABC, bitcoin cash SV, bitcoin diamond, bitcoin gold and others. Some of these forks have caused fragmentation among platforms as to the correct naming convention for forked crypto assets. Due to the lack of a central registry or rulemaking body, no single entity has the ability to dictate the nomenclature of forked crypto assets, causing disagreements and a lack of uniformity among platforms on the nomenclature of forked crypto assets, and which results in further confusion to customers as to the nature of assets they hold on platforms, and which can negatively impact the value of the crypto assets. In addition, several of these forks were contentious and as a result, participants in certain communities may harbor ill will towards other communities. As a result, certain community members may take actions that adversely impact the use, adoption, and price of bitcoin, or any of their forked alternatives.

Furthermore, hard forks can lead to new security concerns. For instance, when the Ethereum and Ethereum Classic networks split in July 2016, replay attacks, in which transactions from one network were rebroadcast on the other network to achieve “double-spending,” plagued platforms that traded Ethereum through at least October 2016, resulting in significant losses to some crypto asset platforms. Similar replay attacks occurred in connection with the bitcoin cash and bitcoin cash SV network split in November 2018. Another possible result of a hard fork is an inherent decrease in the level of security due to the splitting of some mining power across networks, making it easier for a malicious actor to exceed 50% of the mining power of that network, thereby making crypto assets that rely on proof-of-work more susceptible to attack, as has occurred with Ethereum Classic.

We intend to recognize forked and airdropped assets consistent with our custodians. We may not immediately or ever have the ability to withdraw a forked or airdropped bitcoin by virtue of bitcoins that we hold with our custodians. Future forks may occur at any time. A fork can lead to a disruption of networks and our information technology systems, cybersecurity attacks, replay attacks, or security weaknesses, any of which can further lead to temporary or even permanent loss of our and our assets.

The due diligence procedures conducted by us and our liquidity provider to mitigate transaction risk may fail to prevent transactions with a sanctioned entity.

We execute trades through our U.S.-based liquidity providers, and rely on these third parties to implement controls and procedures to mitigate the risk of transacting with sanctioned entities. While we expect our third party service providers to conduct their business in compliance with applicable laws and regulations and in accordance with our contractual arrangements, there is no guarantee that they will do so. Accordingly, we are exposed to risk that our due diligence procedures may fail. If we are found to have transacted in bitcoin with bad actors that have used bitcoin to launder money or with persons subject to sanctions, we may be subject to regulatory proceedings and any further transactions or dealings in bitcoin by us may be restricted or prohibited.

Risks Related to Our Indebtedness

Our indebtedness and liabilities could limit the cash flow available for our operations, expose us to risks that could adversely affect our business, financial condition and results of operations and impair our ability to satisfy our obligations under our debt instruments when they come due.

As of December 31, 2024, we did not have any indebtedness. In January 2025, we issued $100.0 million aggregate principal amount of senior convertible notes. We may also incur additional indebtedness to meet future financing needs. Our indebtedness could have significant negative consequences for our security holders and our business, results of operations and financial condition by, among other things:

increasing our vulnerability to adverse economic and industry conditions;

limiting our ability to obtain additional financing on acceptable terms or at all;

requiring the dedication of a substantial portion of our cash flow from operations to service our indebtedness, which will reduce the amount of cash available for other purposes;

limiting our flexibility to plan for, or react to, changes in our business;

diluting the interests of our existing stockholders as a result of issuing shares of our common stock upon conversion of the notes; and

placing us at a possible competitive disadvantage with competitors that are less leveraged than us or have better access to capital.

Our business may not generate sufficient funds, and we may otherwise be unable to maintain sufficient cash reserves, to pay amounts due under our indebtedness and our cash needs may increase in the future.

We may not have the ability to raise the funds necessary to settle conversions of the notes in cash or to repurchase the notes upon a fundamental change, and our future debt may contain limitations on our ability to pay cash upon conversion or repurchase of the notes.

Holders of our convertible senior notes will have the right, subject to certain conditions and exceptions, to require us to repurchase all or any portion of their notes upon the occurrence of a fundamental change at a fundamental change repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. In addition, upon conversion of the notes, unless we elect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of the notes being converted. However, we may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of notes surrendered therefor or pay cash with respect to notes being converted. In addition, our ability to repurchase the notes or to pay cash upon conversions of the notes may be limited by law, by regulatory authority or by agreements governing our future indebtedness. Our failure to repurchase notes at a time when the repurchase is required by the indenture or to pay any cash payable on future conversions of the notes as required by the indenture would constitute a default under the indenture. A default under the indenture governing the notes or the fundamental change itself could also lead to a default under agreements governing our future indebtedness. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the notes or make cash payments upon conversions thereof.

Certain provisions in the indenture governing the notes may delay or prevent an otherwise beneficial takeover attempt of us.

Certain provisions in the indenture governing the notes may make it more difficult or expensive for a third party to acquire us. For example, the indenture governing the notes requires us, subject to certain conditions and exceptions, to repurchase the notes for cash upon the occurrence of a fundamental change and, in certain circumstances, to increase the conversion rate for a holder that converts its notes in connection with a make-whole fundamental change. A takeover of us may trigger the requirement that we repurchase the notes and/or increase the conversion rate, which could make it more costly for a potential acquirer to engage in such takeover. Such additional costs may have the effect of delaying or preventing a takeover of us that would otherwise be beneficial to investors.

Table of Contents

The conditional conversion feature of the notes, if triggered, may adversely affect our financial condition and operating results.

In the event the conditional conversion feature of the notes is triggered, holders of notes will be entitled to convert their notes at any time during specified periods at their option. If one or more holders elect to convert their notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share), we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity. In addition, even if holders do not elect to convert their notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the notes as a current rather than long-term liability, which would result in a material reduction of our net working capital.

Conversion of the notes may dilute the ownership interest of our stockholders or may otherwise depress the price of our common stock.

The conversion of some or all of the notes may dilute the ownership interests of our stockholders. Upon conversion of the notes, we have the option to pay or deliver, as the case may be, cash, shares of our common stock, or a combination of cash and shares of our common stock. If we elect to settle our conversion obligation in shares of our common stock or a combination of cash and shares of our common stock, any sales in the public market of our common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the existence of the notes may encourage short selling by market participants because the conversion of the notes could be used to satisfy short positions, or anticipated conversion of the notes into shares of our common stock could depress the price of our common stock.

The capped call transactions may affect the value of the notes and our common stock.

In connection with the pricing of the notes, we entered into privately negotiated capped call transactions with certain financial institutions (the “option counterparties”). The capped call transactions cover, subject to customary adjustments, the number of shares of our common stock that initially underlie the notes. The capped call transactions are expected to offset the potential dilution as a result of any conversion of notes. We expect that the option counterparties and/or their respective affiliates may modify or unwind their hedge positions by entering into or unwinding various derivative transactions and/or purchasing or selling our common stock or other securities of ours in secondary market transactions from time to time prior to the maturity of the notes (and are likely to do so on each exercise date of the capped call transactions, which are scheduled to occur during the observation period relating to any conversion of the notes on or after May 1, 2030 that is not in connection with a redemption, or following our election to terminate any portion of the capped call transactions in connection with any repurchase, redemption, exchange or early conversion of the notes). This activity could cause or avoid an increase or a decrease in the market price of our common stock or the notes.

We are subject to counterparty risk with respect to the capped call transactions.

The option counterparties are financial institutions, and we are subject to the risk that one or more of the option counterparties may default or otherwise fail to perform, or may exercise certain rights to terminate, their obligations under the capped call transactions. Our exposure to the credit risk of the option counterparties is not secured by any collateral.

Past global economic conditions have resulted in the actual or perceived failure or financial difficulties of many financial institutions. If an option counterparty becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at the time under such transaction. Our exposure will depend on many factors but, generally, an increase in our exposure will be correlated to an increase in the market price and in the volatility of our common stock. In addition, upon a default by an option counterparty, we may suffer adverse tax consequences and more dilution than we currently anticipate with respect to our common stock. We can provide no assurances as to the financial stability or viability of the option counterparties.

Risks Related to Our Common Stock

Our executive officers, directors and significant stockholders, if they choose to act together, have the ability to substantially influence the outcome of all matters submitted to stockholders for approval.

Our executive officers, directors and significant stockholders beneficially own in the aggregate shares representing approximately 22.3% of our common stock as of January 31, 2025. If these stockholders choose to act together, they are able to substantially influence the outcome of all matters submitted to our stockholders for approval, as well as our management and affairs. For example, these persons, if they choose to act together, can impact the election of directors and approval of any merger, consolidation or sale of all or substantially all of our assets. This concentration of ownership control may:

delay, defer or prevent a change in control;

entrench our management and the board of directors; or

impede a merger, consolidation, takeover or other business combination involving us that other stockholders may desire.

Provisions in our corporate charter documents and under Delaware law could make an acquisition of our company, which may be beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management .

Provisions in our corporate charter and our bylaws may discourage, delay or prevent a merger, acquisition or other change in control of our company that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price of our common stock. In addition, because our board of directors is responsible for appointing the members of our management team, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors. Among other things, these provisions:

allow the authorized number of our directors to be changed only by resolution of our board of directors;

allow for a classified board of directors;

establish advance notice requirements for stockholders proposal that can be acted on at stockholder meeting and nominations to our board of directors; and

limit who may call stockholder meetings.

Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner.

Our amended and restated bylaws designate exclusive forums for the adjudication of certain disputes, which could limit our stockholders’ ability to bring claims in a judicial forum it finds favorable for disputes with us or our directors, officers, or employees.

Our amended and restated bylaws provide that a state or federal court located within the State of Delaware is the sole and exclusive forum for:

Table of Contents

any derivative action or proceeding brought on our behalf;

any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee or stockholder of our company to us or our stockholders;

any action asserting a claim arising pursuant to any provision of the General Corporation Law of the State of Delaware, our charter or our bylaws, as to which the General Corporation Law of the State of Delaware confers jurisdiction on the Court of Chancery of the State of Delaware; and

any action asserting a claim governed by the internal affairs doctrine.

Our amended and restated bylaws further provide that a federal district court of the United States is the sole and exclusive forum for any complaint asserting a cause of action arising under the Securities Act of 1933, as amended or the Securities Act. These provisions further provide that any person or entity that acquires any interest in shares of our capital stock will be deemed to have notice of and consented to these provisions.

These provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers, and other employees. If a court were to find any of these provisions to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving the dispute in other jurisdictions, which could seriously harm our business.

The price of our common stock has been and may continue to be volatile and fluctuate substantially, which could result in substantial losses for purchasers of our common stock .

Our stock price has been and is likely to continue to be volatile. The stock market in general and the market for smaller medical device companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. With the adoption of our new bitcoin strategy, we expect to see additional volatility. As a result of this volatility, you may not be able to sell your common stock. The market price for our common stock may be influenced by many factors, including:

our bitcoin treasury strategy;

the success of competitive products, services or technologies;

regulatory or legal developments in the United States and other countries;

developments or disputes concerning patent applications, issued patents or other proprietary rights;

the recruitment or departure of key personnel;

actual or anticipated changes in estimates as to financial results, development timelines or recommendations by securities analysts;

variations in our financial results or those of companies that are perceived to be similar to us;

changes in the structure of healthcare payment systems;

market conditions in the medical device sector;

general economic, industry and market conditions; and

Table of Contents

the other factors described in this “Risk Factors” section, including the risk that DOJ will file a complaint against our company.

In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been brought against that company. Due to the potential volatility of our stock price, including the risk that DOJ will file a complaint against our company, we may be the target of securities litigation in the future. Securities litigation could result in substantial costs and divert management’s attention and resources from our business.

Because we do not anticipate paying any cash dividends on our capital stock in the foreseeable future, capital appreciation, if any, will be your sole source of gain.

We have never declared or paid cash dividends on our capital stock. We anticipate that we will retain our earnings, if any, for future growth and therefore do not anticipate paying cash dividends in the future. As a result, only appreciation of the price of our common stock will provide a return to stockholders.

General Risk Factors

Because we operate in an industry with significant product liability risk, and we may not be sufficiently insured against this risk, we may be subject to substantial claims against our product or services that we may provide .

The development, manufacture and sale, lease or use of products or provision of services in a medical setting entails significant risks of product liability or other negligence or malpractice claims. Although we maintain insurance to cover us in the event of liability claims, and as of the date of this annual report on Form 10-K, no such claims have been asserted or threatened against us, our insurance may not be sufficient to cover all possible future liabilities regarding our product, or from performing tests with our product or other non-proprietary products. Accordingly, we may not be adequately protected from any liabilities, including any adverse judgments or settlements, we might incur in connection with the development, clinical testing, manufacture and sale, lease or use of our products or the provision of services. A successful product liability or negligence or medical malpractice claim or series of claims brought against us that result in an adverse judgment against or settlement by us in excess of any insurance coverage could seriously harm our financial condition or reputation. Moreover, even if no judgments, fines, damages or liabilities are imposed on us, our reputation could suffer, which could have a material adverse effect on our business, financial condition and results of operations. In addition, product liability and other malpractice insurance is expensive and may not always be available to us on acceptable terms, if at all.

We may implement a product recall or voluntary market withdrawal or stop shipment of our product due to product defects or product enhancements and modifications, which would significantly increase our costs.

The manufacturing and marketing of QuantaFlo and any future products that we may develop involves an inherent risk that our products may prove to be defective. In that event, we may voluntarily implement a recall or market withdrawal or stop shipment or may be required to do so by a regulatory authority. A recall of QuantaFlo or one of our future products, or a similar product manufactured by another manufacturer, could impair sales of the products we market as a result of confusion concerning the scope of the recall or as a result of the damage to our reputation for quality and safety. Further any product recall, voluntary market withdrawal or shipment stoppage of our product could significantly increase our costs and have a material adverse effect on our business.

If we fail to properly manage our operations, our business could suffer.

Our operations have placed, and will continue to place, a significant strain on our management and on our operational and financial resources and systems. Failure to manage our operations effectively could cause us to over-invest or under-invest and result in losses or weaknesses. Additionally, our anticipated operations will increase the demands placed on our suppliers, resulting in an increased need for us to carefully monitor for quality assurance. Any failure by us to manage our operations effectively could have an adverse effect on our ability to achieve our development and commercialization goals.

An information security incident, including a cybersecurity breach, could have a negative impact on our business or reputation.

To meet business objectives, we rely on both internal information technology systems and networks, and those of third parties and their vendors, to process and store sensitive data, including confidential research and patient data that may be subject to legal protection. The extensive information security and cybersecurity threats, which affect companies globally, pose a risk to the security and availability of these information technology systems and networks, and the confidentiality, integrity, and availability of our sensitive data. We continually assess these threats and make investments to increase internal protection, detection, and response capabilities, as well as ensure our third-party providers have required capabilities and controls, to address this risk. To date, we have not experienced any material impact to our business or operations resulting from information or cybersecurity attacks; however, because of the frequently changing attack techniques, along with the increased volume and sophistication of the attacks, there is the potential for us to be adversely impacted. This impact could result in reputational, competitive, operational or other business harm as well as financial costs and regulatory action.

Adverse developments affecting the financial services industry, such as actual events or concerns involving liquidity, defaults, or non-performance by financial institutions or transactional counterparties, could adversely affect our current and projected business operations and our financial condition and results of operations.

Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional counterparties or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, Silicon Valley Bank, or SVB, was closed by the California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation, or FDIC, as receiver. Similarly, on March 12, 2023, Signature Bank and Silvergate Capital Corp. were each swept into receivership. Although we took steps to diversify our banking relationships and are not a borrower or party to any such instruments with SVB, Signature or any other financial institution currently in receivership, if any of our lenders or counterparties to any financial instruments (such as letters of credit) were to be placed into receivership, we may be unable to access such funds. In addition, if any of our customers, suppliers or other parties with whom we conduct business are unable to access funds pursuant to such instruments or lending arrangements with such a financial institution, such parties’ ability to pay their obligations to us or to enter into new commercial arrangements requiring additional payments to us could be adversely affected.

Although the U.S. Department of Treasury, FDIC and Federal Reserve Board have announced a program to provide up to $25 billion of loans to financial institutions secured by certain of such government securities held by financial institutions to mitigate the risk of potential losses on the sale of government securities with interest rates below current market interest rates, widespread demands for customer withdrawals or other liquidity needs of financial institutions for immediately liquidity may exceed the capacity of such program. Additionally, there is no guarantee that the U.S. Department of Treasury, FDIC and Federal Reserve Board will provide access to uninsured funds in the future in the event of the closure of other banks or financial institutions, or that they would do so in a timely fashion.

Although we assess our banking and customer relationships as we believe necessary or appropriate, our access to funding sources and other credit arrangements in amounts adequate to finance or capitalize our current and projected future business operations could be significantly impaired by factors that affect our company, the financial institutions with which we have credit agreements or arrangements directly, or the financial services industry or economy in general.

Fluctuations in insurance cost and availability could adversely affect our profitability or our risk management profile .

We hold a number of insurance policies, including product liability insurance, directors’ and officers’ liability insurance, and workers’ compensation insurance. If the costs of maintaining adequate insurance coverage increase significantly in the future, our operating results could be materially adversely affected. Likewise, if any of our current insurance coverage should become unavailable to us or become economically impractical, we would be required to operate our business without indemnity from commercial insurance providers. If we operate our business without

Table of Contents

insurance, we could be responsible for paying claims or judgments against us that would have otherwise been covered by insurance, which could adversely affect our results of operations or financial condition.

Disruptions at the FDA, the SEC and other government agencies caused by the change in presidential administration, funding shortages or potential funding shortages could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner, or otherwise prevent those agencies from performing normal business functions, which could negatively impact our business and our timelines.

The ability of the FDA to review and clear or approve new products can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, shifting policy priorities as a result of changes in the Presidential administration and political appointees tasked to oversee the agency, and statutory, regulatory, and policy changes. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of the SEC, and other government agencies on which our operations may rely is subject to the impacts of political events, which are inherently fluid and unpredictable. Currently, federal agencies in the United States are operating under a continuing resolution that is set to expire on March 14, 2025.

Disruptions at the FDA and other agencies may slow the time necessary for review and approval (including our expanded indication for QuantaFlo), which could adversely affect our business. For example, over the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA and the SEC to timely review and process our submissions, which could have a material adverse effect on our business and our timelines.

We operate in an intensely competitive and rapidly changing business environment, and there is a substantial risk our products or service offerings could become obsolete or uncompetitive.

The market for medical systems, equipment and other devices and services is highly competitive. We compete with many medical service companies in the United States and internationally in connection with our vascular testing product and products under development. We face competition from numerous companies in the diagnostic area, as well as competition from academic institutions, government agencies and research institutions. Most of our current and potential competitors have, and will continue to have, substantially greater financial, technological, research and development, regulatory and clinical, manufacturing, marketing and sales, distribution and personnel resources than we do. There can be no assurance that we will have sufficient resources to successfully commercialize QuantaFlo or any other future products, if and when they are approved for sale or license, or service offerings that we may develop. Our future success will depend largely upon our ability to anticipate and keep pace with developments and advances. Current or future competitors could develop alternative technologies or products or service offerings that are more effective, easier to use or more economical than what we or any potential licensee develop. If our technologies or products or service offerings become obsolete or uncompetitive, our related revenues would decrease. This would have a material adverse effect on our business, financial condition and results of operations.

Changes in, or interpretations of, tax rules and regulations may adversely affect our effective tax rates.

We are subject to income and other taxes in the United States. Significant judgment is required in evaluating our provision for income taxes or in claiming tax credits or taking other tax positions. During the ordinary course of business, there are many transactions for which the ultimate tax determination is uncertain or if we were to be audited, the Internal Revenue Service, or state tax authorities may not agree with our tax positions. For example, we are subject to various state sales and use tax audits and believe our current exposure could result in an estimated liability of up to $500,000. Further state sales and use tax audits could result in other potential liabilities. In addition, there could be changes in the valuation of our deferred tax assets and liabilities or changes in the relevant tax, accounting, and other laws, regulations, principles and interpretations. Although we believe our tax estimates and practices are reasonable, the final determination of tax audits and any related litigation could be materially different from our historical income tax provisions and accruals. The results of an audit or litigation, or the effects of a change in tax policy in the United States or a particular state, could have a material effect on our operating results in the period or periods for which that

determination is made. In addition, new income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time, which could affect the tax treatment of our earnings. Any new taxes could adversely affect our business operations, and our business and financial performance. Further, existing tax laws, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us.

We are currently a “smaller reporting company,” and the reduced disclosure requirements applicable to such companies may make our common stock less attractive to investors.

We are a “smaller reporting company,” as defined in the Securities Exchange Act of 1934, as amended, or the Exchange Act, and will remain a smaller reporting company for so long as either our annual revenues are less than $100.0 million during the most recently completed fiscal year and our voting and non-voting common stock held by non-affiliates is less than $700.0 million measured on the last business day of our second fiscal quarter, or our voting and non-voting common stock held by non-affiliates is less than $250.0 million measured on the last business day of our second fiscal quarter. For so long as we remain a smaller reporting company, we are permitted and intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not smaller reporting companies. These exemptions include:

being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, with correspondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure; and

reduced disclosure obligations regarding executive compensation.

We have taken advantage of reduced reporting burdens in this annual report on Form 10-K. We cannot predict whether investors will find our common stock less attractive if we rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

We have incurred and will continue to incur increased costs as a result of operating as a public company, and our management has been and will continue to be required to devote substantial time to new compliance initiatives and corporate governance practices.

As a public company, we have incurred and will continue to incur increased costs, and our management has been and will continue to be required to devote substantial time to new compliance initiatives and corporate governance practices. Moreover, after we are no longer a smaller reporting company, we will incur additional significant legal, accounting and other expenses to address compliance and corporate governance. The Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act and other applicable securities rules and regulations impose various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and corporate governance practices. Our management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, the currently applicable rules and regulations have already increased our legal and financial compliance costs and made some activities more time-consuming and costly. We will need to continue to dedicate internal resources, potentially engage outside consultants and continue steps to improve control processes as appropriate, validate through testing that controls are functioning as documented and implement a continuous reporting and improvement process for internal control over financial reporting.

You may experience future dilution as a result of future equity offerings.

In order to raise additional capital or pursue strategic acquisition opportunities, we may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock. For example, we entered into an “at-the-market” offering program in June 2024 and issued convertible notes in January 2025. We cannot assure you that we will be able to sell shares or other securities with conversion prices in any other offering at a price per share that is equal to or greater than the price per share paid by investors in such an offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders.

The price per share at which we sell or issue additional shares of our common stock or other securities convertible into or exchangeable for our common stock in future transactions may be higher or lower than the price at which you purchased your shares.

ITEM 7.   MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATION

The following discussion and analysis should be read together with our financial statements and the related notes appearing elsewhere in this annual report on Form 10-K. This discussion contains forward-looking statements reflecting our current expectations that involve risks and uncertainties. See “Cautionary Note Regarding Forward-Looking Statements and Industry Data” for a discussion of the uncertainties, risks and assumptions associated with these statements. Actual results and the timing of events could differ materially from those discussed in our forward-looking statements as a result of many factors, including those set forth under “Risk Factors” in Item 1A and elsewhere in this annual report on Form 10-K.

Overview

We are a company developing and marketing technology products and services that assist our customers in evaluating and treating chronic diseases. Our patented and FDA cleared product, QuantaFlo measures arterial blood flow in the extremities to aid in the diagnosis of PAD.

We also invest in bitcoin and have adopted bitcoin as our primary treasury reserve asset. As an operating business, we are able to use cash flows as well as proceeds from equity and debt financings to accumulate bitcoin. Our healthcare technology solutions business is our predominant operational focus, providing cash flows and enabling us to pursue our bitcoin strategy.

We are currently seeking a new 510(k) clearance from the FDA for the expanded use of QuantaFlo, which is intended to enable expanded labeling as an aid in the diagnosis of other cardiovascular diseases in addition to PAD. We continue to develop additional complementary proprietary products in-house and seek out other arrangements for additional products and services that we believe will bring value to our customers and to our company. We believe our current products and services, and any future products or services that we may offer, position us to provide valuable information to our customer base, which in turn permits them to better guide patient care.

In the year ended December 31, 2024, we had total revenues of $56.3 million and net income of $40.9 million compared to total revenues of $68.2 million and net income of $20.6 million in 2023. We had an income tax expense of $7.0 million in 2024, compared to $3.5 million in 2023. Our pre-tax net income was $47.9 million, including unrealized

gains from the change in fair value of bitcoin holdings of $24.9 million in 2024 compared to $24.1 million and no gains in 2023.

Recent Developments

Bitcoin Treasury Strategy

In May 2024, we adopted bitcoin as our primary treasury reserve asset on an ongoing basis, subject to market conditions and our anticipated cash needs. As of December 31, 2024, we held an aggregate of 2,298 bitcoins, which we acquired for an aggregate purchase price of $189.7 million and an average purchase price of $82,538 per bitcoin. From January 1, 2025 through February 14, 2025, we have purchased an additional 894 bitcoins, at an aggregate purchase price of $90.7 million and an average purchase price of $101,532. All purchase amounts include fees and expenses.

ATM Offering

In June 2024, we entered into a Controlled Equity Offering SM Sales Agreement with Cantor Fitzgerald & Co., pursuant to which we may offer and sell from time to time our common stock in an at-the-market, or ATM, offering. Through December 31, 2024, we have issued and sold a total of 2,197,988 shares of our common stock for aggregate gross proceeds of approximately $119.6 million.

Offering of 4.25% Convertible Senior Notes

In January 2025, we issued $100.0 million aggregate principal amount of 4.25% convertible senior notes due 2030, or the notes, in a private offering, or the offering to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act, which included $15.0 million pursuant to the exercise in full of the initial purchasers option. The offering size was increased from the previously announced offering size of $75.0 million aggregate principal amount of notes.

The notes are senior unsecured obligations and accrue interest payable semiannually in arrears on February 1 and August 1 of each year, beginning on August 1, 2025, at a rate of 4.25% per year. The notes will mature on August 1, 2030, unless earlier converted, redeemed or repurchased. The initial conversion rate of the notes is 13.0826 shares of our common stock per $1,000 principal amount of such notes (equivalent to an initial conversion price of approximately $76.44 per share). The initial conversion price of the notes represents a premium of approximately 25% over the last reported sale price of our common stock on the Nasdaq Capital Market on January 23, 2025. Upon conversion, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of its common stock, at its election.

We received approximately $91.0 million of net proceeds after deducting the initial purchasers’ discount and other offering expenses payable by us. We used approximately $1.3 million for issuance expenses and approximately $7.7 million of the net proceeds to pay the cost of the capped call transactions that we entered into as described below and the remainder of the net proceeds for general corporate purposes, including the acquisition of bitcoin.

In connection with the pricing of the notes, we entered into privately negotiated capped call transactions, or the capped call transactions with certain financial institutions, or the option counterparties. The capped call transactions cover, subject to customary adjustments, the number of shares of our common stock that will initially underlie the notes. The capped call transactions are expected to offset the potential dilution to our common stock as a result of any conversion of notes, with such reduction subject to a cap. The cap price of the capped call transactions relating to the notes will initially be approximately $107.01, which represents a premium of approximately 75% over the last reported sale price of our common stock on the Nasdaq Capital Market on January 23, 2025, and is subject to certain adjustments under the terms of the capped call transactions. As the initial purchasers exercised their option to purchase additional notes, we entered into additional capped call transactions with the option counterparties on January 24, 2025.

In connection with establishing their initial hedges of the capped call transactions, we expect the option counterparties and/or their respective affiliates may enter into various derivative transactions with respect to our

Table of Contents

common stock and/or purchase our common stock in secondary market transactions concurrently with or shortly after the pricing of the notes, including with certain investors in the notes. This activity could increase (or reduce the size of any decrease in) the market price of our common stock or the notes at that time.

In addition, we expect that the option counterparties and/or their respective affiliates may modify or unwind their hedge positions by entering into or unwinding various derivative transactions and/or purchasing or selling our common stock or our other securities in secondary market transactions following the pricing of the notes and prior to the maturity of the notes (and are likely to do so on each exercise date of the capped call transactions, which are scheduled to occur during the observation period relating to any conversion of the notes on or after May 1, 2030 that is not in connection with a redemption, or following our election to terminate any portion of the capped call transactions in connection with any repurchase, redemption, exchange or early conversion of the notes). This activity could also cause or avoid an increase or a decrease in the market price of our common stock or the notes, which could affect a noteholder’s ability to convert its notes and, to the extent the activity occurs during any observation period related to a conversion of notes, it could affect the amount and value of the consideration that a noteholder will receive upon conversion of its notes.

Neither the notes, nor any shares of our common stock issuable upon conversion of the notes, have been registered under the Securities Act or any state securities laws, and unless so registered, may not be offered or sold in the United States or to, or for the account or benefit of, U.S. persons, absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and other applicable securities laws.

Our Bitcoin Acquisition Strategy

In May 2024, we adopted bitcoin as our primary treasury reserve asset on an ongoing basis, subject to market conditions and our anticipated cash needs. Our strategy includes acquiring and holding bitcoin using cash flows from operations that exceed working capital requirements, and from time to time, subject to market conditions, issuing equity or debt securities or engaging in other capital raising transactions with the objective of using the proceeds to purchase bitcoin. For example, we began issuing shares under our June 2024 “at-the-market” offering program in the second half of 2024, and in January 2025 issued convertible bonds, and used proceeds from both of these capital market transactions to acquire additional bitcoin. We view our bitcoin holdings as long term holdings and expect to continue to accumulate bitcoin. We have not set any specific target for the amount of bitcoin we seek to hold, and we will continue to monitor market conditions in determining whether to engage in additional bitcoin purchases. This overall strategy also contemplates that we may periodically sell bitcoin for general corporate purposes or in connection with strategies that generate tax benefits in accordance with applicable law, enter into additional capital raising transactions, including those that could be collateralized by our bitcoin holdings, and consider pursuing strategies to create income streams or otherwise generate funds using our bitcoin holdings.

Sources of Revenues and Expenses

Revenues

We generate revenues primarily from the rental or license of our vascular testing product. We recognize revenues from the licensing of our vascular testing product pursuant to agreements that normally automatically renew each month with revenues recognized on a daily convention basis. Our arrangements with customers for our vascular testing product are normally on a month-to-month basis with fees billed at the rates established in our customer agreements, which are either fixed fees, or variable fees based on usage. We also recognize revenue for hardware and supplies sales.

Cost of revenues

Our cost of revenues for our vascular testing product consists primarily of five components: the depreciation expense of our vascular testing product for lease; the write-off of the residual value of our vascular testing products retired from active leasing; manufacturing oversight personnel costs; the cost of hardware and supplies sold; and other miscellaneous items, such as freight, that are not directly related to product production. Each vascular testing product unit has a depreciation schedule based on the cost of the unit. The cost of each unit is depreciated on a straight-line basis over 36 months. Each unit has its own cost of production, which varies from time to time. We believe that the cost of each unit is a function of manufacturing efficiencies, supply costs and fixed overhead expense as affected by volume of units produced, which change from time to time. When cost of production is lower, the new units have a lower monthly depreciation and decrease the average depreciation per unit per month, which means our cost of revenues is lower. Similarly, if cost of production is higher, the new units will have a higher monthly depreciation and increase the average depreciation per unit per month, which means our cost of revenues is higher. We believe growth in the number of monthly depreciation charges is predominately due to our sales and marketing efforts, which add new customers to an established customer base. The retirement of units from active leasing is primarily a function of the aggregate number of vascular testing units rented and the occurrence from time to time of system upgrades. The cost of hardware or supplies sold are the cost of production for the item sold. The other costs of revenue vary primarily as a function of the aggregate number of vascular testing units rented and changes in operations such as manufacturing, delivery or maintenance.

Table of Contents

Engineering and product development expense

Our engineering and product development expense consists of costs associated with the design, development, testing and enhancement of QuantaFlo and other products in development. We also include salaries and related employee benefits, research-related overhead expenses and fees paid to external service providers in our engineering and product development expense.

Sales and marketing expense

Our sales and marketing expense consists primarily of sales commissions and support costs, salaries and related employee benefits, travel, education, trade show and marketing costs.

General and administrative expense

Our general and administrative expense consists primarily of salaries and related employee benefits, professional service fees, associated travel costs and depreciation and amortization expense.

Total other income and expense

Our total other income and expense primarily reflects other taxes and fees, interest and dividend income, as well as changes in value and impairments of our investments and digital assets.

Critical Accounting Policies and Estimates

Our accounting policies are more fully described in Note 2 of the financial statements. As disclosed in Note 2, the preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ significantly from those estimates. We do not believe that we have any critical accounting policies and estimates.

Factors Affecting Future Results

We have not identified any other factors that have a recurring effect that are necessary to understand period to period comparisons as appropriate, nor any one-time events that have an effect on the financials. However, we are experiencing and expect to continue to experience decreased usage due to the current CMS reimbursement landscape, which is having a negative effect on our revenues.

Results of Operations

Year Ended December 31, 2024 Compared to Year Ended December 31, 2023

Revenues

We had revenues of $56.3 million for the year ended December 31, 2024, compared to $68.2 million in 2023. Our revenues are primarily from fees charged to customers for use of our products and from sale of accessories used with these products. We recognized revenues of $53.4 million from fees for our products in 2024, consisting of $27.5 million from fixed-fee licenses and $25.9 million from variable-fee licenses, compared to $66.3 million in 2023, consisting of $37.3 million from fixed-fee licenses and $29.0 million from variable-fee licenses. The remainder was from other equipment/supply sales of accessories, which were $2.9 million in 2024 as compared to $1.9 million in 2023.

Revenues from fees for products are recognized monthly, usually billed as a fixed monthly fee or as a variable monthly fee dependent on usage. The primary reason for the decrease in revenues was a decrease in testing volume and the introduction of volume pricing tiers for some of our largest customers, as well as the CMS rate announcement. We

Table of Contents

expect to continue to experience decreased testing volume due to the CMS rate announcement, which we expect will have a negative effect on our revenues.

Operating Expenses

We had total operating expenses of $35.4 million for the year ended December 31, 2024, compared to $45.9 million in 2023. The primary reason for this change was a focus on cost control and strategic streamlining implemented in the third quarter of 2023. As a percentage of revenues, operating expenses, including cost of revenues, decreased to 63% in 2024, as compared to 67% in 2023. The changes in the various components of our operating expenses are described below.

Cost of Revenues

We had cost of revenues of $4.8 million for the year ended December 31, 2024, compared to $7.0 million for 2023. The primary reasons for this change were the lower personnel costs and lower scrap write-off expenses, partially offset by higher material cost. In 2023, there was a one-time write-off of $2.5 million related to the prepayment for Insulin Insights licenses. As a percentage of revenues, cost of revenues was at 8% in 2024, compared to 10% in 2023.

Engineering and Product Development Expense

We had engineering and product development expense of $4.8 million for the year ended December 31, 2024, compared to $5.8 million in 2023. The decrease was primarily due to lower personnel costs, consulting fees and other costs associated with our product development and customization efforts, which were partially offset by higher clinical studies expenses. As a percentage of revenues, engineering and product development expense was unchanged at 9% in both 2024 and in 2023.

Sales and Marketing Expense

We had sales and marketing expense of $13.1 million for the year ended December 31, 2024, compared to $18.1 million in 2023. The decrease was primarily due to lower personnel costs, consulting, trade show, travel and other expenses. As a percentage of revenues, sales and marketing expense decreased to 23% in 2024 compared to 27% in 2023.

General and Administrative Expense

We had general and administrative expense of $12.7 million for the year ended December 31, 2024, compared to $14.3 million in 2023. The decrease was primarily due to lower personnel costs, legal and professional and bad debt expenses, partially offset by higher insurance and dues and subscriptions expenses. As a percentage of revenues, general and administrative expense increased to 22% in 2024, compared to 21% in 2023.

Strategic Operational Streamlining

During the year ended December 31, 2023, we incurred severance cost of $0.7 million consisting of one-time termination benefits, which we have reported on the statement of income under “strategic streamlining”. We did not incur any strategic streamlining expenses during the year ended December 31, 2024.

Other Income and Expense

We had other income of $27.0 million for 2024, compared to $1.8 million in 2023. The change was primarily due to unrealized gains of $24.9 million from the change in fair value of our digital assets.

Table of Contents

Provision for Taxes

In 2024, we recorded income tax expense of $7.0 million, compared to $3.5 million in 2023. In 2024, income tax expenses were partially offset by tax benefits related to employee stock option exercises. I n 2023 lower income tax expense was due to tax benefits from employee stock option exercises and the $2.5 million write-off of the Insulin Insights prepaid licenses.

Net Income

For the foregoing reasons, we had a net income of $40.9 million for the year ended December 31, 2024, compared to a net income of $20.6 million for the year ended December 31, 2023.

Liquidity and Capital Resources

We had cash, cash equivalents, restricted cash and short-term investments of $9.0 million at December 31, 2024, compared to $57.3 million at December 31, 2023, and total current liabilities of $6.3 million at December 31, 2024, compared to $6.2 million at December 31, 2023. As of December 31, 2024, we held 2,298 bitcoins with an aggregate fair value of $214.6 million at such date. Our bitcoin investment is remeasured at fair value at each reporting date with changes recognized in net income through “other income, net” in our statement of income. We recognized an unrealized gain of $24.9 million from the remeasurement of fair value of our digital assets for the year ended December 31, 2024. We did not have any digital assets as of December 31, 2023. As of December 31, 2024, we had working capital of approximately $16.4 million. We believe that our current sources of funds will provide us with adequate liquidity during the 12-month period following December 31, 2024, as well as in the long-term.

In June 2024 we entered into a Controlled Equity Offering℠ Sales Agreement with Cantor Fitzgerald & Co., pursuant to which we may offer and sell from time to time our common stock in an ATM offering. Through December 31, 2024, we have issued and sold a total of 2,197,988 shares of our common stock for aggregate gross proceeds of approximately $119.6 million.

Our cash is held in a variety of non-interest bearing bank accounts and interest bearing money market accounts. At December 31, 2024, we held approximately $3.6 million in government money market fund accounts and the remaining cash was held in non-interest bearing bank accounts. Our investment guidelines allow for holdings in bitcoins, U.S. government and agency securities, corporate securities, taxable municipal bonds, commercial paper, money market accounts and treasury bills. In addition, we have, and may in the future, choose to invest some of our cash resources in other entities that may have complementary technologies or product offerings .

Operating Activities

We generated $24.4 million of net cash from operating activities for the year ended December 31, 2024, compared to $21.3 million of net cash from operating activities for the same period of the prior year. Non-cash adjustments to reconcile net income to net cash from operating activities used net cash of $17.7 million and were primarily due to, an unrealized gain in fair value of bitcoin of $24.9 million, change in the fair value of notes held for investments of $0.1 million, allowance for credit losses of $0.1 million, partially offset by deferred tax income of $5.8 million, stock-based compensation expense of $0.9 million, depreciation of $0.6 million, and loss on disposal of assets for lease of $0.3 million.  Changes in operating assets and liabilities provided $1.2 million of net cash. These changes in operating assets and liabilities included a decrease in accounts receivable of $1.8 million, an increase of accrued expenses of $0.7 million, a decrease in other noncurrent assets of $0.1 million and decrease in inventory of $0.1 million, partially offset by an increase in prepaid expenses and other current assets of $0.9 million, decrease in other current liabilities of $0.3 million and decrease in trade payable of $0.3 million.

Investing Activities

We used $190.0 million of net cash for investing activities for the year ended December 31, 2024, compared to generating $18.4 million of net cash from investing activities for the year ended December 31, 2023. The increase in net cash used was primarily due to purchases of bitcoin of $189.7 million.

Financing Activities

We generated $117.2 million of net cash in financing activities during the year ended December 31, 2024, compared to net cash used of $5.4 million during the year ended December 31, 2023, primarily due to proceeds from the issuance of common stock of $119.6 million under our ATM offering program and proceeds from the exercise of stock options of $1.5 million, partially offset by taxes paid related to equity awards of $0.9 million, and the payment of stock issuance expenses of $3.0 million.

Description of Indebtedness

As discussed above in “—Recent Developments—Offering of 4.25% Convertible Senior Notes,” in January 2025, we issued $100.0 million aggregate principal amount of 4.25% convertible senior notes due 2030. For a description of the material terms of the notes and related capped call transactions, see above and Note 20 “Subsequent Events” to our audited financial statements appearing elsewhere in this annual report on Form 10-K .
