Item 1A. Risk Factors.
In addition to other risks and uncertainties described in this Annual Report, the following risk factors should be carefully considered in evaluating our business because such factors may have a significant impact on our business, operating results, liquidity and financial condition. As a result of the risk factors set forth below, actual results could differ materially from those projected in any forward-looking statements.

Financial and Operating Risks
Our financial condition raises substantial doubt as to our ability to continue as a going concern.
We have had significant losses and negative cash flows in nearly every year since inception, and continue to have an accumulated deficit which, at December 31, 2025, was approximately $455.6 million. Our net loss for the years ended December 31, 2025 and 2024 was approximately $7.4 million and $14.5 million, respectively. Our independent registered public accounting firm has included in their audit opinion on our consolidated financial statements as of and for the year ended December 31, 2025, a statement with respect to substantial doubt about our ability to continue as a going concern. Note 2 to our consolidated financial statements included in Item 8 includes a discussion regarding our liquidity and our ability to continue as a going concern. Our consolidated financial statements have been prepared assuming we will continue to operate as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. If we become unable to continue as a going concern, we may have to liquidate our assets and the values we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected in our consolidated financial statements. The substantial doubt as to our ability to continue as a going concern may adversely affect our ability to negotiate reasonable terms with our vendors and may adversely affect our ability to raise additional capital in the future.
We have had a history of losses which may ultimately compromise our ability to implement our business plan and continue in operation.
With the exception of the year ended December 31, 2023, our technologies and products have not produced revenues sufficient to cover our operating costs. We will continue to make expenditures on patent protection and enforcement and general operations in order to continue our current patent enforcement and licensing efforts. Those efforts may not produce a successful financial outcome in 2026, or at all. Without a successful financial outcome from one or more of our patent enforcement and licensing efforts, we will not achieve profitability. If we are not able to generate sufficient revenues or obtain sufficient capital resources, we may not be able to implement our business plan or meet our current obligations due within the twelve months after the issuance date of our consolidated financial statements and investors will suffer a loss in their investment. This may also result in a change in our business strategies.
We will need to raise substantial additional capital in the future to fund our operations. Failure to raise such additional capital may prevent us from implementing our business plan as currently formulated.
Because we have a history of net losses and negative cash flow from operations, we have funded our operating costs primarily from the sale of debt and equity securities, including our secured and unsecured contingent debt obligations. Our current capital resources include cash and cash equivalents of $4.4 million at December 31, 2025, which will not alone be sufficient to meet our working capital needs for the twelve months following the issuance of our consolidated financial statements. Our business plan will continue to require expenditures for patent protection and enforcement and general operations. If we do not generate sufficient revenues from our licensing and patent enforcement programs, we will require additional capital to fund our operations. Additional capital may be in the form of debt securities, the sale of equity securities, including common or preferred stock, additional litigation funding, or a combination thereof. Failure to raise additional capital may have a material adverse impact on our ability to achieve our business objectives.

Raising additional capital by issuing debt securities or additional equity securities may result in dilution and/or impose covenants or restrictions that create operational limitations or other obligations.
We may require additional capital to fund our operations and meet our current obligations due within the twelve months after the issuance date of our consolidated financial statements. Financing, if any, may be in the form of debt or sales of equity securities, including common or preferred stock. Debt instruments or the sale of preferred stock may result in the imposition of operational limitations and other covenants and payment obligations, any of which may be burdensome to us and may have a material adverse impact on our ability to implement our business plan as currently formulated. The sale of equity securities, including common or preferred stock, may result in dilution to the current shareholders’ ownership and may be limited by the number of shares we have authorized and available for issuance.
We may be obligated to repay outstanding notes at a premium upon the occurrence of an event of default.
We have $3.1 million in outstanding principal under convertible notes at December 31, 2025. If we fail to comply with the various covenants set forth in each of the notes, including failure to pay principal or interest when due or consummating a change in control, we could be in default thereunder. Upon an event of default under each of the notes, the interest rate of the notes will increase to 12% per annum and the outstanding principal balance of the notes plus all accrued unpaid interest may be declared immediately payable by the holders. We may not have sufficient available funds to repay the notes upon an event of default, and we cannot provide assurances that we will be able to obtain other financing at terms acceptable to us, or at all.
Our ability to utilize our tax benefits could be substantially limited if we fail to generate sufficient income or if we experience an “ ownership change. ”
We have cumulative net operating loss carryforwards (“NOLs”) totaling approximately $254.7 million at December 31, 2025, of which $203.9 million is subject to expiration in varying amounts from 2026 to 2037. Our ability to fully recognize the benefits from those NOLs is dependent upon our ability to generate sufficient income prior to their expiration. In addition, our NOL carryforwards may be limited if we experience an ownership change as defined by Section 382 of the Internal Revenue Code (“Section 382”). In general, an ownership change under Section 382 occurs if one or more 5% shareholders increase their collective ownership of the aggregate amount of our outstanding shares by more than 50 percentage points over a relevant lookback period. We have sold a significant number of equity securities over the relevant lookback period which increases the risk of triggering an ownership change under Section 382 from the future sale of additional equity securities. An ownership change under Section 382 will significantly limit our ability to utilize our tax benefits.
Our litigation funding arrangements may impair our ability to obtain future financing and/or generate sufficient cash flows to support our future operations.
We have funded much of our cost of litigation through contingent financing arrangements with Brickell and others and contingent fee arrangements with legal counsel. The repayment obligation to Brickell is secured by the majority of our assets. Furthermore, our contingent arrangements will result in reductions in the amount of net proceeds retained by us from litigation, licensing, and other patent-related activities. The contingent fees payable to legal counsel, Brickell and others will consume all of our initial future proceeds up to specified limits and will likely exceed half of our proceeds thereafter depending on size and timing of proceeds, among other factors. The long-term continuation of our business plan is dependent upon our ability to secure sufficient financing to support our business, and our ability to generate revenues and/or patent related proceeds sufficient to offset expenses and meet our contingent payment obligations. Failure to generate revenue or other patent-related proceeds sufficient to repay our contingent obligations may impede our ability to obtain additional financing which will have a material adverse effect on our ability to achieve our long-term business objectives.

Our litigation can be time-consuming, costly and we cannot anticipate the results.
Since 2011, we have spent a significant amount of our financial and management resources to pursue patent infringement litigation against third parties. We believe this litigation will continue to consume management and financial resources for long periods of time. There can be no assurance that our litigation matters will ultimately result in a favorable outcome for us or that our financial resources will not be exhausted before achieving a favorable outcome. In addition, even if we obtain favorable interim rulings or verdicts in particular litigation matters, they may not be predictive of the ultimate resolution of the matter. Unfavorable outcomes could result in exhaustion of our financial resources and could hinder our ability to pursue licensing and/or product opportunities for our technologies in the future. Failure to achieve favorable outcomes from one or more of our patent enforcement actions will have a material adverse impact on our financial condition, results of operations, cash flows, and business prospects.
If our patents and intellectual property rights do not provide us with the anticipated market protections, our competitive position, business, and prospects will be impaired.
We rely on our intellectual property rights, including patents and patent applications, to provide competitive advantage and protect us from theft of our intellectual property. We believe that our patents are for entirely new technologies and that our patents are valid, enforceable, and valuable. However, third parties have made claims of invalidity with respect to certain of our patents and other similar claims may be brought in the future. For example, the PTAB has issued a number of rulings invalidating claims of certain of our patents as a result of third-party challenges filed by defendants in our patent enforcement actions. If our patents are shown not to be as broad as currently believed or are otherwise challenged such that some or all of the protection is lost, we will suffer adverse effects from the loss of competitive advantage and our ability to offer unique products and technologies. As a result, there would be an adverse impact on our financial condition and business prospects. Furthermore, defending against challenges to our patents may give rise to material costs for defense and divert resources away from our other activities.
Our business, results of operations, and financial condition may be impacted by risks related to pandemics and other similar outbreaks.
The COVID-19 pandemic created significant volatility and uncertainty in financial markets and negatively impacted the timing of our current patent enforcement actions as a result of travel restrictions, office closures and court closures. Future pandemics or other similar outbreaks could likewise adversely impact our business, results of operations and financial condition. For example, market volatility and uncertainty could impact our ability to raise additional capital on terms that are acceptable to us, or at all. Additionally, business shut-downs, court closures, and travel restrictions resulting from future outbreaks could cause material delays in our patent enforcement and licensing program which is currently our sole source of revenue. The extent to which future pandemics or similar outbreaks impact our ongoing business strategy, as well as our results of operations and financial condition, generally, will depend on future developments which are highly uncertain and cannot be predicted, including the severity and duration of the outbreak and the actions taken by governments and private businesses to contain or treat its impact, among others. If the disruptions posed by future pandemics or outbreaks continue for an extensive period of time, our business, results of operations, and financial condition may be materially adversely affected.

We are subject to outside influences beyond our control, including new legislation that could adversely affect our licensing and enforcement activities and have an adverse impact on the execution of our business plan.
Our licensing and enforcement activities are subject to numerous risks from outside influences, including new legislation, regulations and rules related to obtaining or enforcing patents. For instance, over the past decade, the U.S. has enacted sweeping changes to the U.S. patent system including changes that transition the U.S. from a “first-to-invent” to a “first-to-file” system and other changes that alter the processes for challenging issued patents. To the extent that we are unable to secure patent protection for our future technologies and/or our current patents are challenged such that some or all of our protection is lost, we will suffer adverse effects to our ability to offer unique products and technologies. As a result, there would be an adverse impact on our financial position, results of operations and cash flows and our ability to execute our business plan.
Our industry is subject to rapid technological changes which if we are unable to match or surpass, will result in a loss of competitive advantage and market opportunity.
Because of the rapid technological development that regularly occurs in the wireless technology industry, along with shifting user needs and the introduction of competing products and services, we have historically devoted substantial resources to developing and improving our technology and introducing new product offerings. As a result of our limited financial resources, we have ceased our research and development activities which could result in a loss of future market opportunity which could adversely affect our future revenue potential.
We are highly dependent on Mr. Jeffrey Parker as our chief executive officer. If his services were lost, it would have an adverse impact on the execution of our business plan.
Because of Mr. Parker’s leadership position in the Company, the relationships he has garnered in both the industry in which we operate and the investment community and the key role he plays in our patent litigation strategies, the loss of his services might be seen as an impediment to the execution of our business plan. If Mr. Parker was no longer available to the Company, investors might experience an adverse impact on their investment. We maintain a $1.5 million key-man life insurance policy on Mr. Parker.
If we are unable to retain key highly skilled employees, we will not be able to execute our current business plans.
Our business is dependent on having skilled and specialized key employees to conduct our business activities. The inability to retain these key employees would have an adverse impact on the technical support activities and the financial reporting and regulatory compliance activities that our business requires. These activities are instrumental to the successful execution of our business plan.

Any disruptions to our information technology systems or breaches of our network security could interrupt our operations, compromise our reputation, and expose us to litigation, government enforcement actions, and costly response measures and could have a material adverse effect on our business, financial condition, and results of operations.
We rely on information technology systems, including third-party hosted servers and cloud-based servers, to keep business, financial, and corporate records, communicate internally and externally, and operate other critical functions. If any of our internal systems or the systems of our third-party providers are compromised due to computer virus, unauthorized access, malware, and the like, then sensitive documents could be exposed or deleted, and our ability to conduct business could be impaired. Cyber incidents can result from deliberate attacks or unintentional events. These incidents can include, but are not limited to, unauthorized access to our systems, computer viruses or other malicious code, denial of service attacks, malware, ransomware, phishing, SQL injection attacks, human error, or other events that result in security breaches or give rise to the manipulation or loss of sensitive information or assets. Cyber incidents can be caused by various persons or groups, including disgruntled employees and vendors, activists, organized crime groups, and state-sponsored and individual hackers. Cyber incidents can also be caused or aggravated by natural events, such as earthquakes, floods, fires, power loss, and telecommunications failures. The risk of cybersecurity breach has generally increased as the number, intensity, and sophistication of attempted attacks from around the world has increased. While we have cyber security procedures in place, given the evolving nature of these threats, there can be no assurance that we will not suffer material losses in the future due to cyber-attacks.
To date, we have not experienced any material losses relating to cyber-attacks, computer viruses or other systems failures. Although we have taken steps to protect the security of data maintained in our information systems, it is possible that our security measures will not be able to prevent the systems’ improper functioning or the improper disclosure of personally identifiable information, such as in the event of cyber-attacks. In addition to operational and business consequences, if our cybersecurity is breached, we could be held liable to our customers or other parties in regulatory or other actions, and we may be exposed to reputation damages and loss of trust and business. This could result in costly investigations and litigation, civil or criminal penalties, fines, and negative publicity.
Risks Relating to our Common Stock
Our outstanding options and warrants may affect the market price and liquidity of the common stock.
At December 31, 2025, we had 143.2 million shares of common stock outstanding and had outstanding options, restricted share units, and warrants for the purchase of up to 29.3 million additional shares of common stock, the majority of which were exercisable as of December 31, 2025. In addition, as described more fully below, holders of convertible notes may elect to receive up to 24.7 million shares of common stock upon conversion of the notes, and we may elect to pay accrued interest on the notes in shares of our common stock. The majority of the shares of common stock underlying these securities are currently registered for sale to the holder or for public resale by the holder. The amount of common stock reserved for issuance may have an adverse impact on our ability to raise capital and may affect the price and liquidity of our common stock in the public market. In addition, the issuance of these shares of common stock will have a dilutive effect on current shareholders’ ownership.

The conversion of outstanding convertible notes into shares of common stock, and the issuance of common stock by us as payment of accrued interest upon the convertible notes, could materially dilute our current shareholders.
We have an aggregate principal amount of $3.1 million in convertible notes outstanding at December 31, 2025. The notes are convertible into shares of our common stock at fixed conversion prices, which may be less than the market price of our common stock at the time of conversion. If the entire principal were converted into shares of common stock, we would be required to issue an aggregate of up to 24.7 million shares of common stock. If we issue all of these shares, the ownership of our current shareholders will be diluted.
Further, we may elect to pay interest on the notes, at our option, in shares of common stock, at a price equal to the then-market price for our common stock. From 2018 to 2025, we issued an aggregate of approximately 10.1 million shares of common stock as in-kind interest payments on our convertible notes. We currently do not believe that we will have the financial ability to make payments on the notes in cash when due. Accordingly, we currently intend to make such payments in shares of our common stock to the greatest extent possible. Such interest payments could further dilute our current shareholders.
The price of our common stock may be subject to substantial volatility.
The trading price of our common stock has been and may continue to be volatile. Between January 1, 2024 and March 1, 2026, the reported high and low sales prices for our common stock ranged between $0.09 and $1.18 per share. The price of our common stock may continue to be volatile as a result of a number of factors, some of which are beyond our control. These factors include, but are not limited to, developments in outstanding litigation, our performance and prospects, general conditions of the markets in which we compete, and other economic and financial conditions. Such volatility could materially and adversely affect the market price of our common stock in future periods.
Our common stock is quoted on OTCQB, an over-the-counter market. There can be no assurance that our common stock will continue to trade on the OTCQB or on another over-the-counter market or securities exchange.
Our common stock began trading on the OTCQB, an over-the-counter market, in August 2018 under the symbol “PRKR”. The over-the-counter market is a significantly more limited market than a nationally-recognized securities exchange such as Nasdaq, and the quotation of our common stock on the over-the-counter market has resulted in a less liquid market available for existing and potential shareholders to trade shares of our common stock. Securities traded in the over-the-counter market generally have less liquidity due to factors such as the reduced number of investors that will consider investing in the securities, the reduced number of market makers in the securities, and the reduced number of securities analysts that follow such securities. As a result, holders of shares of our common stock may find it difficult to resell their shares at prices quoted in the market or at all. We are also subject to additional compliance requirements under applicable state laws relating to the issuance of our securities. This could have a long-term adverse effect on our ability to raise capital, which ultimately could adversely affect the market price of our common stock. We cannot provide any assurances as to if or when we will be in a position to relist our common stock on a nationally-recognized securities exchange.

Our common stock has been classified as a “ penny stock ” from time to time under SEC rules, which means broker-dealers who make a market in our stock may be subject to additional compliance requirements.
Our common stock has been deemed to be a "penny stock" in prior periods, as defined in the Securities Exchange Act of 1934 (the “Exchange Act”). Penny stocks are stocks (i) with a price of less than five dollars per share; (ii) that are not traded on a recognized national exchange; (iii) whose prices are not quoted on an automated quotation system sponsored by a recognized national securities association; or (iv) whose issuer has net tangible assets less than $2,000,000 (if the issuer has been in continuous operation for at least three years); or $5,000,000 (if continuous operations for less than three years); or with average revenues of less than $6,000,000 for the last three years. The Exchange Act requires broker-dealers dealing in penny stocks to provide potential investors with a document disclosing the risks of penny stocks and to obtain a manually signed and dated written receipt of the document before effecting any transaction in a penny stock for the investor’s account. Potential investors in our common stock are urged to obtain and read such disclosure carefully before purchasing any shares that are deemed to be “penny stock.” Further, the Exchange Act requires broker-dealers dealing in penny stocks to approve the account of any investor for transactions in such stocks before selling any penny stock to that investor. These procedures require the broker-dealer to (i) obtain from the investor information concerning his, her or its financial situation, investment experience and investment objectives; (ii) reasonably determine, based on that information, that transactions in penny stocks are suitable for the investor, and that the investor has sufficient knowledge and experience as to be reasonably capable of evaluating the risks of penny stock transactions; (iii) provide the investor with a written statement setting forth the basis on which the broker dealer made the determination in (ii) above; and (iv) receive a signed and dated copy of such statement from the investor, confirming that it accurately reflects the investor’s financial situation, investment experience and investment objectives. Although our stock is not currently classified as a penny stock, there can be no assurance that we will not revert to penny stock status in the future. Compliance with the penny stock requirements may affect the ability or willingness of broker-dealers to sell our securities, and accordingly would affect the ability of shareholders to sell their securities in the public market. These additional procedures could also limit our ability to raise additional capital in the future.
We do not currently pay dividends on our common stock and thus shareholders must look to appreciation of our common stock to realize a gain on their investments.
We do not currently pay dividends on our common stock and intend to retain our cash and future earnings, if any, to fund our business plan. Our future dividend policy is within the discretion of our Board and will depend upon various factors, including our business, financial condition, results of operations and capital requirements. We therefore cannot offer any assurance that our Board will determine to pay special or regular dividends in the future. Accordingly, unless our Board determines to pay dividends, shareholders will be required to look to appreciation of our common stock to realize a gain on their investment. There can be no assurance that this appreciation will occur.
Provisions in our certificate of incorporation and by-laws could have effects that conflict with the interest of shareholders.
Some provisions in our certificate of incorporation and by-laws could make it more difficult for a third party to acquire control of us. For example, our Board is divided into three classes with directors having staggered terms of office, our Board has the ability to issue preferred stock without shareholder approval, and there are advance notification provisions for director nominations and submissions of proposals from shareholders to a vote by all the shareholders under the by-laws. Florida law also has anti-takeover provisions in its corporate statute.
