YoY shift: Lean -

Year-over-year tone shift - average net-tone change across Risk Factors and MD&A vs the prior 10-K. This filing is -0.24pp more bearish than last year's.

Why YoY instead of absolute: the LM lexicon has ~6.6× more negative words than positive (legal/risk-disclosure language is heavy on hedging), so every 10-K reads bearish on raw tone. Year-over-year change strips that bias and surfaces the actual shift in management's framing.

Item 1A. Risk Factors

Risks Related to Operations of Our Business

A significant portion of our revenues is generated by large, recurring business from certain significant customers, including the U.S. government. Any loss, cancellation or delay in one or more projects by our significant customers in the future could negatively affect our financial performance.

A considerable percentage of our revenues, particularly in our MTS business segment, is generated under contracts with certain significant customers. Revenues from the U.S. government represented 57% of our total consolidated revenues for fiscal 2025. Budget uncertainty, the potential for U.S. government shutdowns, the use of continuing resolutions and the federal debt ceiling can adversely affect our industry and the funding for our contracts. In addition, government acquisition reform and spending cut initiatives, including executive orders, may impact our business. For example, on January 20, 2025, an executive order was signed to create an advisory commission, DOGE, to reform federal government processes and reduce expenditures. Although DOGE was disbanded in November 2025, we cannot rule out the possibility of similar initiatives occurring in the future. Further, on April 15, 2025, Executive Order 14275, “Restoring Common Sense to Federal Procurement,” was signed, directing major revisions to the FAR to make the government’s procurement process more efficient, and on November 7, 2025, the U.S. DoW released a memorandum and strategy on defense acquisition reform titled “Transforming the Warfighting Acquisition System” that aims to overhaul the procurement landscape and prioritizes speed to capability delivery. If appropriations are delayed, a government shutdown were to occur and continue for an extended period of time, or changes in budgetary priorities or U.S. government spending levels were to occur, we could be at risk of contract cancellations, contract options not being exercised, funding shortages, nonpayment, increased uncertainty in the conversion of our book to bill to revenue and other disruptions and nonrepayment. When the U.S. government operates under a continuing resolution, new contract starts are restricted and funding for our programs may be unavailable, reduced or delayed. Shifting funding priorities or federal budget compromises also could result in reductions in overall defense spending on an absolute or inflation-adjusted basis, which could negatively affect our business, financial performance and condition. In addition, if we are unable to effectively respond to proposed acquisition reform in the U.S., our ability to secure and perform government contracts could be adversely affected, which may negatively impact our business, financial condition and results of operations. If we are deemed to be underperforming on our contracts, our business, financial condition and results of operations may likewise be adversely impacted.

We depend on U.S. and foreign government agencies as our primary customers in our MTS business segment and, if our reputation or relationships with these agencies were to be harmed, it could adversely impact our financial performance.

We derive a considerable portion of our revenues in our MTS business segment from contracts with agencies and departments of the U.S., the U.K. and Australia governments, either as a prime contractor or as a subcontractor to other companies performing prime contracts for these governments. We expect to continue to derive a significant portion of our revenues from work performed under or relating to U.S. and foreign government contracts. Our relationship with the U.S. and foreign governments is key to maintaining these contracts, winning new work, and growing our revenues. Negative press reports or publicity, regardless of accuracy, could harm our reputation and jeopardize our business with our customers, potentially adversely affecting our business, financial condition, results of operations and cash flows.

Our results of operations and cash flows depend on the award of new contracts and the timing of the performance of existing contracts.

Our revenues are directly and indirectly derived from contract awards. Reductions in the number and amounts of new awards, delays in the timing of anticipated awards or potential cancellations of such prospects as a result of economic conditions, funding priorities, material and equipment pricing and availability or other factors could adversely impact our long-term projected results. It is particularly difficult to predict whether or when we will receive large-scale projects as these contracts usually involve a lengthy and complex bidding and selection process. This process can be affected by a number of factors, including market conditions and governmental and environmental approvals, and in some cases, the customer's ability to secure the necessary financing for a project to proceed. As a portion of our revenues is generated from such projects, our results of operations and cash flows can fluctuate significantly from quarter to quarter depending on the timing of our contract awards and the commencement or progress of work under awarded contracts. The uncertainty of our contract award timing can also present difficulties in matching workforce size with contract needs. In some cases, we maintain and bear the cost of a ready workforce that is larger than necessary under existing contracts in expectation of future workforce needs for anticipated contract awards. If an anticipated contract award is or not received, we may incur additional costs resulting from reductions in staff or redundancy of facilities that could have a material effect on our business, financial condition, results of operations and cash flows.

Following contract award, we may also encounter significant expense, delay, contract modifications or even contract loss

or termination. For example, HomeSafe, a joint venture with Tier One Relocation, informed us on June 18, 2025, that U.S. Transportation Command unexpectedly terminated HomeSafe’s role in the Global Household Goods Contract. KBR owns a 72% interest in HomeSafe. As of January 2, 2026, all of HomeSafe's operations, including run-off operations, have ceased.

Additionally, certain contract awards (including the performance of such awards) have been and may in the future be contested and/or otherwise involved in ongoing bid protests, legal proceedings, inquiries or other similar developments outside of our control, which may result in significant delays in the project timeline or the wholesale cancellation or termination of a project. Any project delays, cancellations or contract modifications following the award of a contract could have a material adverse effect on our business, financial condition, results of operations, backlog, revenue recognition timing and cash flows.

Ongoing international conflicts, and other geopolitical conditions, may adversely affect our business and results of operations.

Political, economic and other conditions in foreign countries and regions, including geopolitical risks, such as the current conflict between Russia and Ukraine, political and economic instability in Venezuela and political and economic instability and ongoing conflict in the Middle East, may adversely affect our business and operations as a portion of our revenue is derived from foreign operations. Additionally, the full scope, duration and broader implications of international conflicts, which may include additional international sanctions, embargoes, regional instability and geopolitical shifts; increased tensions between the United States and countries in which we operate; and the extent of a conflict's effects on our business and results of operations as well as the global economy, cannot be predicted. Any alleged or actual failure to comply with any sanctions and trade control measures implemented in response to international conflicts may subject us to government , civil and/or proceedings, sanctions and other liabilities, which may have an effect on our international operations, financial condition and results of operations.

To the extent current conflicts or other geopolitical conflicts adversely affect our business, they may also have the effect of heightening many of our other risks identified in this Annual Report on Form 10-K, any of which could materially and adversely affect our business and results of operations. Such risks include, but are not limited to, the following:

• adverse effects on macroeconomic conditions, including inflation, demand for our products and potential recessionary economic conditions;

• increased cyber security threats;

• adverse changes in trade policies, taxes, government regulations and tariffs;

• our ability to obtain compensation for increased costs incurred related to rising costs of equipment, materials and labor on fixed-price contracts;

• our ability to implement and execute our business strategy;

• disruptions in global supply chains;

• our exposure to foreign currency fluctuations; and

• constraints, volatility or disruption in the capital markets.

Uncertainty over global tariffs, or the financial impact of tariffs, may negatively impact our business and results of operations.

Our business and results of operations could be adversely impacted by trade restrictions imposed by the U.S. and other governments globally, as well as by changes in these governments’ approaches to tariffs and other trade policies. New or increased tariffs or trade bans could have an adverse effect on both our U.S. and international operations due to increased costs of materials, disruptions or delays in deliveries, and greater difficulty in planning and operating our business. While our business in the U.S. primarily provides labor services to our customers, some of our U.S. work involves procuring goods, equipment or materials that may be subject to tariffs. Our non-U.S. work could also be impacted by greater costs for goods sourced from the U.S. due to increased tariffs imposed by other countries. Although we plan to continue to monitor trade policy developments closely and to mitigate the adverse impacts of any changes where possible, we may not be able to fully mitigate such impacts in all situations.

If there are any successful intellectual property infringement proceedings against us, our competitive position could be adversely impacted.

We utilize a variety of proprietary and third-party technologies in providing services to our customers. We view our portfolio of process and design technologies as one of our competitive strengths and we use it as part of our efforts to differentiate our service offerings. We may not be able to successfully preserve our proprietary intellectual property rights in the future, and these rights could be invalidated, circumvented, challenged or infringed upon. In addition, the laws of some foreign countries in which our services may be sold do not protect intellectual property rights to the same extent as the laws of the U.S. We also license technologies from third parties and there is a risk that our relationships with licensors may terminate, expire or be interrupted or harmed. If we are unable to protect and maintain our intellectual property rights, or if there are any intellectual property or proceedings us, our ability to differentiate our service offerings could . In addition, if our intellectual property rights or work processes become , we may not be to differentiate our service offerings and some of our competitors may be to offer more services to our customers. We will also need to continue to respond to and anticipate changes resulting from technologies, including in areas of artificial intelligence and machine learning. If we are not in protecting and preserving our intellectual property rights and licenses, or in staying ahead of developing artificial intelligence and machine learning technologies and strategically incorporating them into our business, our business and financial performance could be materially and affected.

We may not properly leverage or appropriately invest in technology advancements, which could diminish any sustainable competitive advantage in our service offerings resulting in the potential loss of market share and profits.

We operate in global markets with customers who demand innovation, technical and domain expertise and digitally-enabled, technology-led solutions. Robust information technology systems, platforms and products are integral in our efforts to differentiate our service offerings and maintain our competitive advantages. Disruptive technologies, including in areas of artificial intelligence and machine learning, are rapidly changing the environment in which we, our customers, and our competitors operate and could affect the nature of how we generate revenue. We will need to continue to respond to and anticipate these changes by enhancing our product and service offerings to maintain our competitive position. If we are not successful in staying ahead of developing artificial intelligence and machine learning technologies and strategically incorporating them into our business, our business and financial performance could be materially and adversely affected.

It is strategically important that we lead the digital transformation occurring in our industry. However, we may not be successful in structuring our technology or developing, acquiring or implementing technology systems in ways that are competitive and responsive to the needs of our customers. We may lack sufficient resources to continue to make the significant technology investments to effectively compete with our competitors. Certain technology initiatives that management considers important to our long-term success will require capital investment, have significant risks associated with their execution and could take several years to implement. If we are unable to develop and implement these initiatives in a cost-effective, timely manner or at all, it could damage our relationships with our customers and negatively impact our financial condition and results of operations. There can be no assurance that others will not acquire similar or superior technologies sooner than we do or that we will acquire technologies on an exclusive basis or at a significant price . If we do not accurately predict, prepare and respond to new technology , market developments and changing customer needs, our revenues, and long-term competitiveness could be materially affected.

We may use artificial intelligence, machine learning, data science and similar technologies in our business, and challenges with properly managing such technologies could result in reputational harm, competitive harm and legal liability, and adversely affect our business, financial condition and results of operations.

Artificial intelligence, machine learning, data science and similar technologies (collectively, “AI”), including third-party AI tools, may be enabled by, or integrated into some of our business and solutions. As with many developing technologies, AI presents risks and challenges that could affect its further development, adoption, and use, and therefore our business. AI algorithms may be flawed, biased or produce incorrect information. Datasets used to train or develop AI systems may be insufficient, of inferior quality, or contain biased information. Additionally, the laws and regulations concerning the use of AI continue to evolve. If the use or integration of AI systems, or the outputs generated by such systems, were determined to be non-compliant (e.g., in relation to intellectual property or data privacy rights), this may result in liability or adversely affect our business, reputation, brand, financial condition and results of operations. It is possible that emerging regulations may limit or block the use of AI in our business and solutions or otherwise impose other restrictions that may affect or impair the usability or of our business or services for an extended period of time or indefinitely. Our competitors or other third parties may incorporate AI into their product development, product offerings, technology and infrastructure products more quickly or more

successfully than us, which could impair our ability to compete effectively and adversely affect our business, financial condition and results of operations.

If we are unable to attract and retain senior management and key technical professionals with elite skills and appropriate government qualifications, our ability to pursue and compete for projects to grow our business may be adversely affected, our operating income may decrease and our reputation may be negatively impacted.

KBR's forward-looking strategy requires talent with dynamic and elite skills as KBR moves upmarket. Our rate of growth and the success of our business depend upon our ability to attract, develop, retain and replace key qualified technical and management professionals, either through direct hires, subcontracts or acquisition of other firms, who possess the elite skills to successfully deliver the solutions strategy. The market for these professionals is competitive in the sectors in which we compete, and we rely heavily upon the expertise and leadership of our professionals to perform, execute and complete projects as required by our clients.

We currently hold government-issued facility security clearances and a large number of our employees have qualified for and hold U.S., U.K. and Australian government-issued personal security clearances necessary to perform certain U.S., U.K. and Australian government contracts. Obtaining and maintaining security clearances for employees involves lengthy processes, and it is difficult to identify, recruit and retain employees who already hold security clearances. If our employees are unable to obtain or retain security clearances or if our employees who hold security clearances terminate employment with us and we are unable to find replacements with equivalent security clearances, we may be unable to perform our obligations to customers whose work requires cleared employees, or such customers could terminate their contracts or decide not to renew them upon their expiration. Our facility security clearances could be marked as "invalid" for several reasons including unapproved foreign ownership, control or influence, mishandling of classified materials or failure to properly report required activities. An to obtain or retain our facility security clearances or engage employees with the required security clearances for a particular contract could us from bidding for and new contracts with security requirements or result in consequences for current contracts, including for if security are not remedied.

If we are unable to attract and retain a sufficient number of elite skilled professionals with appropriate government qualifications, our ability to pursue and execute projects may be adversely affected, our operating income may decline, and our reputation may be damaged. Our future success depends on the continued services of our executive officers as well as our ability to effectively transition to their successors. If we are unable to attract, develop and retain qualified employees that can succeed our executive officers, or if our succession plans and/or succession planning processes do not yield the results we intend or expect, there could be a material adverse effect on our operating income and reputation.

The nature of our business exposes us to potential liability claims and contract disputes that may exceed or be excluded from existing insurance coverage.

We engage in activities where failures can result in substantial injury or damage to employees or other third parties or service delivery impacts, exposing us to legal proceedings, investigations and disputes. The nature of our business results in clients, subcontractors and vendors occasionally presenting claims against us for recovery of costs they incurred in excess of what they expected to incur or for which they believe they are not contractually liable. If it is determined that we have liability, we may not be covered by insurance or, if covered, the dollar amount of these liabilities may exceed our policy limits. Our professional liability coverage is on a “claims-made” basis covering only claims actually made during the policy period currently in effect. In addition, even where insurance is maintained for such exposures, the policies have deductibles, which result in our assumption of exposure for a layer of coverage with respect to any such claims. We also manage and maintain a portion of our retained risk through our wholly owned captive insurance company, which insures certain up to the applicable deductible amount of our third-party insurance programs. Additionally, our captive insurance company is a registered and licensed insurance company with the Texas Department of Insurance, and is therefore subject to various rules and regulations including meeting certain capital requirements, which can result in additional use of our resources such as securing the captive insurance company's retained risks with issuing letters of credit. Any liability not covered by our insurance, in excess of our insurance limits or if covered by insurance but subject to a high deductible, could result in a significant for us, which may reduce our profits and cash available for operations. Furthermore, there is risk of mass casualty or environmentally events that may involve our and third-party personnel and property, which could lead to future and , impact our reputation and investor confidence and ultimately result in reduced share price.

We occasionally bring claims against customers for additional costs exceeding the contract price or for amounts not included in the original contract price. These types of claims occur due to matters such as customer-caused delays, changes from the initial project scope or other economic changes not stipulated under the contract that may result in additional direct and indirect costs. Often these claims can be the subject of lengthy negotiations, arbitration or litigation proceedings, and it is difficult to accurately predict when these claims will be fully resolved. When these types of events occur and unresolved claims are pending, we may invest significant working capital in projects to cover cost overruns pending the resolution of the relevant claims. A failure to recover on these types of fully or promptly could have a material impact on our liquidity and financial results.

Dependence on third-party subcontractors, suppliers and equipment manufacturers could adversely affect our financial performance on contracts.

We rely on third-party subcontractors, suppliers and equipment manufacturers in order to complete many of our projects. Certain subcontractors and suppliers, such as those used on our U.S. government contracts, are subject to the same rigorous government requirements that we are and if they are unable to comply with these requirements, in many cases, there are limited alternative subcontractors and suppliers available in the market, particularly those with the requisite security clearances. Our subcontractors may be subject to various regulations to engage in motor carrier service, including regulations from the Department of Transportation, Federal Motor Carrier Safety Administration and various state agencies. The failure of our subcontractors to comply with these regulations could adversely affect our financial performance on certain contracts.

We sometimes have disputes with our contracting parties, including disputes regarding the cost, quality and timeliness of work performed or customer concerns about the other party’s performance. We also have been and in the future could be adversely affected by actions or issues experienced by our contracting parties that are outside of our control, such as misconduct and reputational issues involving our contracting parties, which has and could in the future subject us to liability and reputational harm or adversely affect our ability to compete for contract awards. In addition, if any subcontractor or a manufacturer is unable to deliver its services, equipment or materials according to the negotiated terms for any reason including, but not limited to, the deterioration of its financial condition, we may be required to purchase the services, equipment or materials from another source at a higher price. This may reduce the profit we expect to realize or result in a loss on a project for which the services, equipment or materials were needed. Furthermore, if the amount we are required to pay for these goods and services exceeds the amount we have estimated in bidding for fixed-price contracts, we could experience in the performance of these contracts.

Employee, agent or partner misconduct, or our overall failure to comply with laws or regulations, could weaken our ability to win contracts, which could result in reduced revenues and profits.

We are subject to the risk of misconduct, fraud, non-compliance with applicable laws and regulations, or other improper activities by our employees, agents or partners, which could have a significant negative impact on our business and reputation. Such misconduct includes the failure to comply with government procurement regulations, regulations regarding the protection of classified information, regulations prohibiting bribery and other corrupt practices, regulations regarding the pricing of labor and other costs in government contracts, regulations on lobbying or similar activities, regulations pertaining to the internal controls over financial reporting, regulations pertaining to export control, environmental laws, employee wages, pay and benefits, and any other applicable laws or regulations. For example, we routinely provide services that may be highly sensitive or that relate to critical national security matters and, if a security breach were to occur, our ability to receive future government contracts could be limited. The precautions we take to prevent and detect these activities may not be and we could face unknown risks or . Our to comply with applicable laws or regulations or acts of subject us to the risk of civil or and , of contracts, of security clearance and or from contracting, any of which could our reputation, our ability to contracts and result in reduced revenues and profits and could have a material impact on our business, financial condition and results of operations.

We depend on our teaming arrangements and relationships with other contractors and subcontractors. If we are not able to maintain these relationships, or if these parties fail to satisfy their obligations to us or the customer, our business, financial condition and results of operations could be adversely affected.

We rely on teaming relationships with other prime contractors and subcontractors to bid on large procurements and other opportunities when we believe the combination of services, products and solutions we can offer with teammates will help us win and perform the contract. Our future revenues and growth could be adversely affected if our partners reduce or end their contract relationships with us, or if the U.S. government terminates or reduces programs of prime contractors to which we subcontract, does not award them new contracts, or refuses to pay under a contract. We may contract with subcontractors that

do not have experience on U.S. government contracts or with our customers, providing them with the experience, relationships, and past performance to compete with us on future contracts and potential result in contract losses. If subcontractors fail to timely meet their contractual obligations or have regulatory compliance or other problems, our ability to fulfill our obligations as a prime contractor or higher tier subcontractor may be jeopardized.

We use estimates in recognizing revenues, and if we make changes to estimates used in recognizing revenues, our profitability may be adversely affected.

A significant portion of our revenues and profits are measured and recognized over time using the cost-to-cost method of revenue recognition. Our use of this accounting method results in recognition of revenues and profits over the life of a contract, based on the proportion of costs incurred to date to total costs expected to be incurred for the entire project. The effects of revisions to estimated revenues and costs are recorded when the amounts are known or can be reasonably estimated. In addition, we record unapproved change orders and claims against clients as well as estimated recoveries of claims against suppliers and subcontractors that have been included in the estimated profit at completion for certain projects. Revisions to these estimates could occur in any period and their effects could be material. The uncertainties inherent in estimating the progress towards completion or the recoverability of claims of long-term contracts make it possible for actual revenues and costs to vary materially from our estimates, including reductions or reversals of previously recorded revenues and profits.

We conduct a portion of our operations through joint ventures and partnerships, exposing us to risks and uncertainties, many of which are outside of our control.

We conduct a portion of our operations through project-specific joint ventures where control may be shared with unaffiliated third parties or control may be held by the unaffiliated third parties. These projects include the facilitation of nonrecourse financing, the design and construction of facilities, the provision of operation and maintenance services and warranty obligations for an agreed-upon period after the facilities have been completed. If a project is unable to obtain financing, we could incur losses on our investments and any related contractual receivables. As with any joint venture arrangement, differences in views among the joint venture partners may result in delayed decisions or in failures to agree on major issues. We also cannot control the actions of our joint venture partners, including failure to comply with applicable laws or regulations, nonperformance and default or bankruptcy of our joint venture partners. Also, we often share liabilities on a joint and several basis with our joint venture partners under these arrangements. If our partners do not meet their contractual obligations, the joint venture may be to perform and deliver its contracted services, requiring us to make additional investments or perform additional services to ensure the adequate performance and delivery of services to the customer, which could ultimately result in . We could be liable for both our obligations and those of our partners, which may result in reduced profits, significant on the project and a impact to our cash flows. Additionally, these factors could have a material effect on the business operations of the joint venture and, in turn, our business operations and reputation.

Operating through joint ventures in which we have a minority interest could result in us having limited control over many decisions made with respect to projects and internal controls relating to projects. These joint ventures may not be subject to the same requirements regarding internal controls that are applicable to us. As a result, internal control issues may arise, which could have a material adverse effect on our financial condition and results of operations.

The nature of our contracts, particularly those that are fixed-price, subjects us to risks associated with cost overruns, operating cost inflation and potential claims for liquidated damages.

We conduct our business under various types of contracts where costs must be estimated in advance of our performance. A portion of the value of our current backlog is attributable to fixed-price contracts where we bear a significant portion of the risk of cost overruns. These types of contracts are priced, in part, on cost and scheduling estimates that are based on assumptions including pricing and availability of experienced labor, equipment and materials as well as productivity, performance and future economic conditions. If these estimates prove inaccurate, if there are errors or ambiguities as to contract terms or specifications, or if circumstances change due to, among other things, increases in interest rates, continued inflation, supply-chain disruptions, tariffs, unanticipated technical problems, poor project execution, difficulties in obtaining permits or approvals, changes in local laws or labor conditions, weather delays, increased costs of equipment and materials from inflation or other factors or our suppliers’ or subcontractors’ inability to perform, then cost may occur. Our approach to include annual price escalations in our bids for multi-year work may be to counter inflationary cost pressures, which may result in significant cost on our contracts. This could result in reduced profits on a contract, on a contract and impacts to our cash flows, and our longer-term multi-year contracts could become less to us over time.

We may not be able to obtain compensation for additional work performed or expenses incurred. Additionally, we have in the past and may in the future be required to pay liquidated damages upon our failure to meet schedule or performance requirements of our contracts. Our failure to accurately estimate the resources and time required for fixed-price contracts or our failure to complete our contractual obligations within a specified time frame or cost estimate could result in reduced profits or, in certain cases, a loss for that contract. If the contract is significant, or we encounter issues that impact multiple contracts, cost overruns or schedule delays could have a material adverse effect on our business, financial condition and results of operations.

Our backlog of unfilled orders is subject to unexpected adjustments and cancellations and, therefore, may not be a reliable indicator of our future revenues or earnings.

As of January 2, 2026, the future revenues we expect to realize as a result of backlog was approximately $16.9 billion. Of this amount, we currently estimate that 83% will be recognized in revenues on our consolidated statement of operations and 17% will be recorded by our unconsolidated joint ventures. We cannot guarantee that the revenues projected in our backlog will be realized or that the projects will be profitable. Many of our contracts are subject to cancellation, termination or suspension at the discretion of the customer. From time to time, changes in project scope may occur with respect to contracts reflected in our backlog and could reduce the dollar amount of our backlog or the timing of the revenues and profits that we ultimately earn. Projects may remain in our backlog for an extended period of time because of the nature of the project and the timing of the particular services or equipment required by the project. Delays, suspensions, cancellations, payment defaults, scope changes and poor project execution could materially reduce or eliminate profits that we actually realize from projects in backlog. We cannot predict the impact that future economic conditions may have on our backlog, which could include a ability to replace backlog once projects are completed or could result in the , modification or of projects currently in our backlog. Such developments could have a material effect on our financial condition, results of operations and cash flows.

We have made and may continue to make business combinations as a part of our business strategy, which may present certain risks and uncertainties.

We may continue to seek business acquisitions as a means of broadening our offerings and capturing additional market opportunities by our business segments. However, there is no guarantee that we will be successful in identifying target companies that meet our criteria for acquisition. We may also face increased competition from other potential acquirers who have greater financial resources or who are in a position to offer more favorable terms to the target company. This competition may limit our ability to pursue acquisition opportunities which could negatively affect our growth strategies. Additionally, future acquisitions may require us to obtain additional equity or debt financing, which may not be available on attractive terms, if at all.

The success of our historical and future business combinations also depends on our ability to integrate the operations of the acquired businesses efficiently and effectively with our existing operations and realize the anticipated benefits from them. The potential risks associated with successful integration and realization of benefits include, but are not limited to the following:

• our due diligence may not identify or fully assess valuation issues, potential liabilities or other acquisition risks;

• acquired entities may not achieve anticipated revenue targets, cost savings or other synergies or benefits, or acquisitions may not result in improved operating performance, which could adversely affect our operating income or operating margins, and we may be unable to recover investments in any such acquisitions;

• we may have difficulty integrating acquired businesses, resulting in unforeseen difficulties, such as incompatible accounting, information management or other control systems, and greater expenses than expected;

• we may have difficulty entering into new markets in which we are not experienced, in an efficient and cost-effective manner while maintaining adequate standards, controls and procedures;

• key personnel within an acquired organization may resign from their related positions resulting in a significant loss to our strategic and operational efficiency associated with the acquired company;

• the effectiveness of our daily operations may be reduced by the redirection of employees and other resources to acquisition and integration activities;

• we may assume liabilities of an acquired business (including litigation, tax liabilities, contingent liabilities, environmental issues), including liabilities that were unknown at the time of the acquisition, that pose future risks to our working capital needs, cash flows and the profitability of related operations;

• we may assume unprofitable projects that pose future risks to our working capital needs, cash flows and the profitability of related operations; or

• business acquisitions may include substantial transactional costs to complete the acquisition that exceed the estimated financial and operational benefits.

International and political events may adversely affect our operations.

A portion of our revenues is derived from foreign operations, which exposes us to risks inherent in doing business in each of the countries where we transact business. The occurrence of any of the risks described below could have a material adverse effect on our business operations and financial performance. With respect to any particular country, these risks may include, but not be limited to:

• expropriation and nationalization of our assets in that country;

• changes in government regimes and other developments that may cause, directly or indirectly, political and economic instability;

• costs to maintain the safety of our personnel and clients in high-risk locations, including but not limited to, certain parts of Africa and the Middle East, where the country or surrounding area is suffering from political, social or economic issues, war or civil unrest;

• changes in trade policies affecting the markets for our services (including but not limited to retaliatory tariffs between the United States and other countries);

• civil unrest, acts of terrorism, war or other armed conflict (including but not limited to potential U.S. sanctions on other countries);

• currency fluctuations, devaluations and conversion restrictions;

• confiscatory taxation or other adverse tax policies;

• uncertainties related to any geopolitical, economic and regulatory effects or changes due to recent or upcoming domestic and international elections;

• governmental activities or judicial actions that limit or disrupt markets, restrict payments, limit the movement of funds, result in the deprivation of contract rights or result in the inability for us to obtain or retain licenses required for operation;

• increased polarization of political parties, in the U.S. and abroad, which may lead to more volatility in government spending or other developments such as trade wars or changes in military priorities; or

• failure or refusal of foreign governments or their agencies to acknowledge or honor rights, exemptions or obligations identified in applicable status of forces agreements or treaties.

Due to the unsettled political conditions in countries where we provide governmental logistical support, our financial performance is subject to the adverse consequences of war, the effects of terrorism, civil unrest, strikes, currency controls and governmental actions. In addition, despite safety precautions, military action or unrest could disrupt our operations in such locations and elsewhere and increase our costs related to security worldwide.

Internal or external cybersecurity or privacy breaches, or systems and information technology interruption or failure could adversely impact our ability to operate or expose us to significant financial losses and reputational harm.

As a government contractor and a provider of services operating in multiple regulated industries and geographies, we and our business partners (including our service providers, joint venture partners, suppliers and subcontractors) handle a variety of sensitive information including personally identifiable information, personnel information, protected health information, classified and controlled unclassified information, and financial information, concerning our business, employees and customers. We and our business partners are continuously exposed to cyber and other security threats, including cyberattacks such as malware/computer viruses, ransomware and phishing attacks, insider threats related to malicious and non-malicious activities from authorized and unauthorized employees or third parties, catastrophic events, power outages, natural disasters, computer system or network failures or physical break-ins. We also utilize third-party software in the performance of certain accounting, project management, and financial reporting systems. Technological developments in artificial intelligence and machine learning, particularly those that provide actors with the capability to use more sophisticated means to attack our systems, may cybersecurity and data privacy risks. Any electronic or physical or other security may the protection of sensitive or other information stored or transmitted through our IT systems and networks and those of our business partners and third-party software providers. This could lead to in our business and result in decreased performance, significant remediation costs, reputational , transaction , of data (including personally identifiable information), data leakage of confidential information, processing , , and the of suppliers or customers. Under certain contracts with the U.S. government subject to the FAR and CAS, the adequacy of our business processes and related systems could be called into . Any significant or could have a material effect on our business operations, financial performance, financial condition and reputation.

Additionally, we work with the defense industrial base industry and the U.S., U.K. and Australian governments to gather and share threat intelligence and promote increased awareness and enhanced protections against cybersecurity threats.

However, because of the evolving nature of these security threats, there can be no assurance that our policies, procedures and other controls will detect or prevent them, and we cannot predict their full impact. We may experience similar security threats to the IT systems that we develop, install or maintain under customer contracts, including customer contracts under which we may have access to or management responsibility for customer databases or networks that contain sensitive information relating to our customers, their employees or related third parties. Although we work cooperatively with our customers to seek to minimize the impacts of cyber and other security threats, we must usually rely on the safeguards used or required by those customers. In the event of unauthorized access to sensitive information for which we are responsible under customer contracts, our customers, their employees, or third parties may seek to hold us liable for any costs or other damages associated with the unauthorized access. In addition, government agencies may bring legal actions against us for violation of or noncompliance with regulatory requirements relating to any access to sensitive information. Any remediation costs, or other liabilities related to access of sensitive information of ours or our customers caused by cyber or other security may not be fully insured or indemnified by other means or our insurers. Occurrence of any access caused by these security could affect our reputation, business operations and financial results.

While we have security measures and technology in place designed to protect our and our clients’ proprietary or classified information, there can be no assurance that our efforts will prevent all threats to our computer systems. Because the techniques used to obtain unauthorized access or sabotage systems change frequently, become more sophisticated and generally are not identified until they are launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. As a result, we may be required to expend significant resources to protect against the threat of system disruptions and security breaches or to alleviate problems caused by these disruptions and breaches. Any of these events could damage our reputation, cause us to incur significant liability and have a material effect on our business, financial condition and results of operations.

We continuously evaluate the need to upgrade and/or replace our systems and network infrastructure to protect our digital environment, to stay current on vendor supported products and to improve the efficiency of our systems and for other business reasons. The implementation of new systems and information technology could adversely impact our operations by imposing substantial capital expenditures, demands on management time and risks of delays or difficulties in transitioning to new systems. In addition, our systems implementations may not result in productivity improvements at the levels anticipated. Systems implementation disruption and any other information technology disruption, if not anticipated and appropriately mitigated, could have a material adverse effect on our business.

In addition, laws and regulations governing data privacy and the unauthorized disclosure of personal data, including the European Union General Data Protection Regulation, the United Kingdom Data Protection Act, the California Consumer Privacy Act, the California Privacy Rights Act and other emerging U.S. state and global privacy laws pose increasingly complex compliance challenges and potentially elevate costs and may require changes to our business practices resulting from the variation of regulatory requirements and increased enforcement frequency. Failure to comply with these laws and regulations, including related regulatory enforcement and/or private litigation resulting from a potential privacy breach, could result in governmental investigations, significant fines and penalties, damages from private causes of action or reputational harm. Additionally, we are subject to laws, rules and regulations regarding cross-border transfers of personal data, including laws relating to transfer of personal data outside the European Economic Area. If we cannot rely on existing mechanisms for transferring personal data, we may be to transfer personal data of employees and clients in those regions, which could affect our business, financial condition and operating results.

An impairment of all or part of our goodwill or our intangible assets could have a material adverse impact on our net earnings and net worth.

As of January 2, 2026, we had $2,677 million of goodwill and $727 million of intangible assets recorded on our consolidated balance sheets. Goodwill represents the excess of cost over the fair market value of net assets acquired in business combinations. We perform an annual analysis of our goodwill on the first day of the fourth fiscal quarter to determine if it has become impaired. In addition, we perform interim analyses to determine if our goodwill has become impaired if events occur or circumstances change that would more likely than not reduce our enterprise fair value below its book value. These events or circumstances could include a significant change in the business climate, including a significant sustained decline in a reporting unit’s market value, legal factors, operating performance indicators, competition, sale or disposition of a significant portion of our business, potential government actions toward our facilities and various other factors. If the fair value of a reporting unit is less than its carrying value, we could be required to record an impairment charge. An impairment of all or a part of our goodwill or intangible assets could have a material adverse effect on our net earnings and net worth.

Our actual results could differ from the estimates and assumptions used to prepare our financial statements.

The preparation of our consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of certain assets, liabilities, revenues and expenses for the periods covered and certain amounts disclosed in the notes to our consolidated financial statements statements in Part II, Item 8 of this Annual Report on Form 10-K. These estimates are based on information available through the date of the issuance of the financial statements and actual results could differ from those estimates, which could have a material adverse impact on our financial condition, results of operations and cash flows.

Global pandemics, epidemics, outbreaks of infectious diseases or public health crises have disrupted our business and could have a material adverse effect on our future results of operations and financial performance.

Pandemics, epidemics, outbreaks of infectious diseases or public health crises across the globe have disrupted, and may in the future disrupt our business, which could materially and adversely affect our financial condition, results of operations, cash flows and/or future expectations. Our business, operations and financial performance have been, and may be affected by macroeconomic impacts resulting from pandemics, infectious disease outbreaks and public health crises. As a result, our financial performance and growth rates may differ from historical periods, and our future results may fall below expectations. Any health crisis may negatively affect worldwide economic and commercial activity, disrupt global supply chains and the labor market and create significant volatility and disruption of financial and commodity markets. The extent to which our business will continue to be affected and may in the future be affected by pandemics, infectious disease outbreaks and other public health crises depends on a number of factors outside of our control, including but not limited to the extent and duration of labor , business operations from quarantines, travel restrictions and other requirements imposed by regulators and health authorities, , modifications and of contracts, supply chain , increased cybersecurity and data protection risks, increased costs of doing business and other macroeconomic .

We ship a significant amount of cargo using seagoing vessels, exposing us to certain maritime risks.

We execute different projects in remote locations around the world and procure equipment and materials on a global basis. Depending on the type of contract, location, nature of the work and the sourcing of equipment and materials, we may charter seagoing vessels under time and bareboat charter arrangements and assume certain risks typical of those agreements. Such risks may include damage to the ship, liability for cargo and liability that charterers and vessel operators have to third parties “at law.” In addition, we ship a significant amount of cargo and are subject to hazards of the shipping and transportation industry.

Risks Related to the Planned Spin-Off of Mission Technology Solutions

We are subject to risks related to our plan to spin off our Mission Technology Solutions business into a standalone, publicly traded company.

On September 24, 2025, we announced our intent to spin off our Mission Technology Solutions business to create a separate, U.S. publicly-traded company (the "Planned Spin-Off"). The Planned Spin-Off is intended to be tax-free to us and our shareholders for U.S. federal income tax purposes and targeting completion in the second half of fiscal 2026. The Planned Spin-Off will be subject to final approval by our Board of Directors and other customary conditions, including receipt of a favorable opinion of legal counsel and/or a private letter ruling from the U.S. Internal Revenue Service with respect to the tax treatment of the transaction for U.S. federal income tax purposes, the effectiveness of a registration statement on Form 10 filed with the SEC, satisfactory completion of financing, and other regulatory approvals. We cannot assure you that we will be able to satisfy the necessary conditions or that we will successfully complete the anticipated separation in our preferred structure, on the anticipated timeline or at all. Unanticipated developments, including possible delays in obtaining various tax rulings or regulatory approvals, uncertainty or in the financial markets or other market conditions, changes in our cash requirements, in establishing the new company’s organizational structure, infrastructure or processes, or business performance could or prevent the proposed separation or cause the proposed separation to occur on terms or conditions that are less and/or different than expected, including without , the to qualify as tax-free to our shareholders (which could result in significant income tax liabilities to us and/or our shareholders), and the of the spun-off company to incur sufficient indebtedness to allow for a distribution to us of proceeds concurrently with the consummation of the Planned Spin-Off. Expenses incurred to the proposed separation may be significantly higher than what we currently anticipate. Executing the proposed separation also requires significant time and attention from management, which could them from other tasks in operating our business. Even if the transaction is completed, we may not realize some or all of the anticipated benefits from the separation and we cannot you that the separation will yield benefits to KBR and its shareholders than if such transaction had not occurred. Any of these factors could

negatively impact our business, financial condition, results of operations, cash flows, and the price of our common stock. Additionally, following the proposed separation, the combined value of the common stock of the two publicly-traded companies may not be equal to or greater than what the value of our common stock would have been had the separation not occurred.

Following the Planned Spin-Off, we and the spun-off Mission Technology Solutions business may face stranded costs, loss of economies of scale, and higher operating expenses than currently anticipated, which could materially adversely affect our profitability.

Following the Planned Spin-Off, we will be a smaller, less diversified company than we were prior to the Planned Spin-Off, which could make us more vulnerable to factors impacting our performance, such as changing market conditions and market volatility. As integrated parts of a larger organization, both businesses currently benefit from shared corporate functions, including finance, legal, human resources, information technology, procurement, and other administrative services. Following the Planned Spin-Off, each company will need to replicate these functions independently or secure them from third-party providers, likely at a higher combined cost than the current shared service model.

The two companies may also lose purchasing power and negotiating leverage with suppliers, service providers, and other vendors. Economies of scale in areas such as insurance coverage, employee benefits, technology licenses, real estate, and professional services fees may be diminished. In addition, we may be unable to find suitable alternatives for services that the spun-off entity temporarily provides to us pursuant to transition agreements, or such alternative services may be more expensive. There is also a risk that certain costs currently treated as variable may become fixed at the standalone entity level, reducing our operational flexibility. While management has developed estimates of the costs to operate as independent companies, actual costs may significantly exceed these projections due to factors that cannot be fully anticipated prior to spin-off.

Our operations may be significantly disrupted during and following the Planned Spin-Off process, and we will be dependent on the spun-off entity’s performance under various transition agreements, the failure of which could materially harm our business.

The process of spinning off integrated business operations is highly complex and involves the disentanglement of shared systems, processes, contracts, and infrastructure that have developed over many years. In connection with the Planned Spin-Off, we and the spun-off entity may enter into various agreements that provide for the performance of certain services or provision of goods by each company for the benefit of the other, for example, a transition services agreement, a tax matters agreement, an employee matters agreement, and other related agreements. Performance under these agreements or other related conditions outside of our control could materially affect our operations and future financial results.

During the transition period, we may be dependent on the spun-off entity to continue providing critical services such as IT infrastructure, supply chain functions, or other operational support. If the spun-off entity is unable to satisfy these obligations, including its indemnification obligations, we could incur operational difficulties or losses that could have an adverse effect on our business, financial condition, and results of operations. Service degradation, system failures, or disagreements regarding service levels or pricing under transition services agreements could disrupt our operations. Furthermore, we may face challenges in transitioning to alternative service providers or in-house capabilities before transition services agreements expire, potentially creating gaps in critical business functions.

The Planned Spin-Off process also requires the migration and spin-off of information technology systems, including enterprise resource planning systems, customer relationship management platforms, and other critical business applications. Data migration errors, system integration failures, or cybersecurity vulnerabilities created during the spin-off process could result in business disruption, data loss, or security breaches.

Risks Related to Our Industry

The U.S. government awards its contracts through a rigorous competitive process and our efforts to obtain future contracts from the U.S. government may be unsuccessful.

The U.S. government conducts a rigorous competitive process for awarding most contracts. In the services arena, the U.S. government uses multiple contracting approaches. Historically, omnibus contract vehicles have been used for work that is done on a contingency or as-needed basis. In more predictable “sustainment” environments, contracts may include fixed-price, cost-reimbursable and time-and-materials elements. The U.S. government also favors multiple award task order contracts in

which several contractors are selected as eligible bidders for future work. Such processes require successful contractors to continually anticipate customer requirements and develop rapid-response bid and proposal teams as well as maintain supplier relationships and delivery systems to react to emerging needs. In addition, U.S. government procurement practices sometimes emphasize price over qualitative factors, such as technical capability and past performance. As a result of these competitive pricing pressures, our profit margins on future U.S. government contracts may be reduced and may require us to make sustained efforts to reduce costs to remain competitive.

We face rigorous competition and pricing pressures for any additional contract awards from the U.S. government. Many of our existing contracts must be recompeted when their original period of performance ends, representing opportunities for competitors to take market share away from us or for our customers to obtain more favorable terms. We may be required to qualify or continue to qualify under the various multiple award task order contract criteria. Therefore, it may be more difficult for us to win future awards from the U.S. government and we may have other contractors sharing in U.S. government awards that we win. Once a contract is awarded, it may be subject to a lengthy protest process. Bid protests can result in significant expenses to us, contract modifications or even loss of the contract award and the resolution can extend the time until contract activity can begin and delay the recognition of sales and defer underlying cash flows and affect our operating results. Our efforts to or any bids for contracts that were not awarded to us also may be .

Our profitability and cash flow may vary based on the mix of our contracts and programs, our performance and our ability to control costs.

Our profitability and cash flow may vary materially depending on the types of government contracts undertaken, the nature of services performed under those contracts, the costs incurred in performing the work, the achievement of other performance objectives and the stage of performance at which the right to receive fees is determined, particularly under award and incentive-fee contracts. Failure to perform to customer expectations and contract requirements may result in reduced fees or losses and may adversely affect our financial performance.

Our MTS business segment primarily performs work in the U.S. under cost-reimbursable contracts with the DoW and other U.S. governmental agencies. If the U.S. government concludes costs charged to a contract are not reimbursable under the terms of the contract or applicable procurement regulations, these costs are disallowed or, if already reimbursed, we may be required to refund the reimbursed amounts to the customer. Such conditions may also include interest and other financial penalties.

Contract types primarily include fixed-price and cost-reimbursable contracts. Cost-reimbursable contracts provide for the payment of allowable costs incurred during performance of the contract plus a fee up to a ceiling based on the amount that has been funded. Cost, schedule or technical performance issues with respect to cost-reimbursable contracts could result in reduced fees, lower profit rates, or program cancellation.

Under fixed price contracts, we receive a fixed price irrespective of the actual costs we incur and therefore we carry the burden of any cost overruns. Due to the fixed-price nature of the contracts, if our actual costs exceed our estimates, our margins and profits are reduced and we could incur a loss on the respective contract which could adversely affect our financial results.

Under both fixed-price and cost-reimbursable contracts, if we are unable to control costs, our operating results could be adversely affected. Costs to complete a contract may increase for many reasons, including technical and manufacturing challenges, schedule delays, workforce-related issues, the timeliness and availability of materials from suppliers, internal and subcontractor performance or product quality issues, inability to meet cost reduction initiatives or achieve efficiencies from digital transformation, changing laws or regulations, inflation and natural disasters. Certain contracts may impose other risks, such as forfeiting fees, paying penalties, or providing replacement systems in the event of performance failure. Many of our contracts include multiple option years exercisable at the customer’s discretion, which carries risk. The customer may decline to exercise an option, or the customer may exercise an option on a contract for which we expect to incur a or perform at a low margin, either of which could affect our financial results.

The U.S. government may issue or revise existing rules, regulations and directives, adopt new contract rules and regulations or revise its procurement practices in a manner adverse to us at any time.

We face rigorous competition and pricing pressures for any additional contract awards from the U.S. government. Our industry has experienced, and we expect it will continue to experience, significant changes to business practices as a result of an increased focus on affordability, efficiencies and recovery of costs, among other items. From time to time, new laws, executive orders and regulations are enacted, and government agencies adopt new interpretations and enforcement priorities relative to

laws and regulations already in effect, including recent U.S. government initiatives such as the FAR overhaul under E.O. 14275, DOGE and defense acquisition reform. U.S. government agencies have and may continue to face restrictions or pressure regarding the type and amount of services that they may obtain from private contractors. Legislation, regulations and initiatives dealing with procurement reform as well as any resulting shifts in the buying practices of U.S. government agencies, such as increased usage of fixed-price contracts, multiple-award contracts and small business set-aside contracts, could have adverse effects on government contractors, including us. In addition, U.S. government procurement practices sometimes emphasize price over qualitative factors, such as technical capability and past performance. As a result of these competitive pricing pressures, our profit margins on future U.S. government contracts may be reduced and may require us to make sustained efforts to reduce costs to remain competitive.

Our programs for the U.S. government often operate for periods of time under Undefinitized Contract Actions (UCAs), which means that we begin performing our obligations before the terms, specifications or price are finally agreed to between the parties. The U.S. government has (and has exercised in the past) the ability to unilaterally definitize contracts, which, absent a successful appeal, obligates us to perform under terms and conditions imposed by the U.S. government. This can affect our ability to negotiate mutually agreeable contract terms and, if a contract is unilaterally imposed upon on us, it may negatively affect our expected profit and cash flows on a program or impose burdensome terms.

Federal legislation, regulations, executive orders, and other initiatives dealing with, among other things, procurement reform, the mitigation of potential OCIs, the deterrence of fraud, the elimination of diversity, equity, and inclusion, and changes in corporate environmental obligations, could affect our business. Additionally, we are subject to the laws and regulations of the states in which we operate, which, at times, may conflict with federal laws and regulations, introducing ambiguity.

The ongoing FAR overhaul and other reforms to the U.S. government acquisition process, including changes to procurement rules and regulations, could transform how contracts are awarded, negotiated, and managed, which could lead to delays in contract awards and/or modifications to the scope or terms of contracts we hold. We could face increased competition, greater scrutiny, a more complex regulatory environment, heightened compliance requirements, and additional administrative burdens, all of which have the potential to affect our profitability.

Heightened competition could impact our ability to obtain contracts which could reduce our market share and profits.

We serve markets that are global and highly competitive. We compete with larger companies that have greater name recognition, financial resources and a larger technical staff. We also compete with smaller, more specialized companies that are able to concentrate their resources on particular areas. Additionally, we compete with the U.S. government’s own capabilities.

The markets in which we operate are characterized by rapidly changing technology and the needs of our customers changing and evolving regularly. Therefore, our success depends on our ability to invest in and develop our people and technology to enable us to deliver services and products that address these changing needs. To remain competitive, we must consistently provide superior service, technology and performance on a cost-effective basis to our customers while understanding customer priorities and maintaining customer relationships. Our competitors may be able to provide our customers with differentiated or superior capabilities or technologies or more attractive contract terms than we can provide, including technical qualifications, past contract experience, geographic presence, price and the availability of qualified professional personnel. Some of our competitors have made or could make acquisitions of businesses, or establish teaming or other agreements among themselves or third parties, that allow them to offer more competitive and comprehensive solutions. As a result of such acquisitions or arrangements, our current or potential competitors may be able to accelerate the adoption of new technologies that address customer needs, devote resources to bring these products and services to market, initiate or withstand substantial price competition or develop and expand their product and service offerings at a more accelerated rate. These competitive pressures in our market or our to compete effectively may result in fewer orders, reduced revenue and margins and of market share.

Our U.S. government contract work is regularly reviewed and audited by the U.S. government, U.S. government auditors and others, and these reviews can lead to withholding or delay of payments to us, non-receipt of award fees, legal actions, fines, penalties and liabilities and other remedies against us.

U.S. government contracts are subject to specific regulations such as the FAR, the Truthful Cost or Pricing Data Statute, CAS, the Service Contract Act and DoW security regulations. Failure to comply with any of these regulations, requirements or statutes may result in contract price adjustments, financial penalties or contract termination. Our U.S. government contracts are subject to audits, cost reviews and investigations by U.S. government contracting oversight agencies such as the DCAA. The DCAA reviews the adequacy of, and our compliance with, our internal control systems and policies, including our labor, billing, accounting, purchasing, property, estimating, compensation and management information systems. The DCAA has the

authority to conduct audits and reviews to determine if we are complying with the requirements under the FAR and CAS, pertaining to the allocation, period assignment and allowability of costs assigned to U.S. government contracts. The DCAA presents its report findings to the DCMA. Should the DCMA determine that we have not complied with the terms of our contract or applicable statutes and regulations, payments to us may be disallowed, which could result in adjustments to previously reported revenues and refunding of previously collected cash proceeds. Additionally, we previously have been, and may in the future be subject to additional qui tam litigation brought by private individuals on behalf of the U.S. government under the Federal False Claims Act, which could include claims for treble damages. These suits may remain under seal (and hence, be unknown to us) for some time while the U.S. government decides whether to intervene on behalf of the qui tam plaintiff.

Given the demands of working for the U.S. government, we may have disagreements or experience performance issues. When performance issues arise under any of our U.S. government contracts, the U.S. government retains the right to pursue remedies, which could include termination under any affected contract. If any contract were so terminated, our ability to secure future contracts could be adversely affected. Other remedies that could be sought by our U.S. government customers for any improper activities or performance issues include sanctions such as withholding of payments, liquidated damages and suspensions or debarment from doing business with the U.S. government. Further, the negative publicity that could arise from disagreements with our customers or sanctions as a result thereof could have an adverse effect on our reputation in the industry, reduce our ability to compete for new contracts and may also have a material effect on our business, financial condition, results of operations and cash flows.

Several of our contracts with the U.S. government are classified or subject to other security restrictions, which may limit investor insight into portions of our business.

A significant portion of our revenue is from contracts with the U.S. government that are classified or subject to security restrictions that preclude the disclosure of certain information. Additionally, a large number of our employees have security clearances which prohibit them from providing information to investors and other KBR employees without security clearances regarding certain clients and the related services we provide to them. As we are limited in our ability to provide information about these contracts and services, such as the scope of work, associated risks and any disputes or claims, our investors may have limited insight into a substantial portion of our business which may hinder their ability to fully evaluate the risks related to that portion of our business.

Demand for our services provided under government contracts is directly affected by spending by our customers.

We derive a significant portion of our revenues from contracts with agencies and departments of the U.S., the U.K. and Australia governments, which is directly affected by changes in government spending priorities and availability of adequate funding. Additionally, government regulations generally include the right for government agencies to modify, delay, curtail, renegotiate or terminate contracts at their convenience any time prior to their completion. As we are a significant government contractor, our financial performance is affected by the allocation and prioritization of government spending. Factors that could affect current and future government spending include:

• policy or spending changes, or changes in enforcement priorities or resource allocation, implemented by the current administrations, war/defense departments or other government agencies;

• advisory commissions created to review budgetary priorities, including efficiency initiatives such as DOGE;

• increased polarization of political parties;

• failure to pass budget appropriations, continuing funding resolutions or other budgetary decisions, including any failure of the U.S. federal government to manage its fiscal matters or to raise or further suspend the debt ceiling;

• changes, delays or cancellations of government programs or requirements;

• adoption of new laws, regulations or policies, or repeal of existing laws, regulations or policies, that affect companies providing services to the governments;

• reduced buying power as a result of inflation;

• curtailment of the governments’ outsourcing of services to private contractors; or

• the level of political instability due to war, conflict or natural disasters.

We face uncertainty with respect to our government contracts due to the political, fiscal, economic and budgetary challenges facing our customers. Potential contract delays, modifications or terminations may arise from resolution of these issues and could cause our revenues, profits and cash flows to be lower than our current projections. The loss of work we perform for governments or decreases in governmental spending and outsourcing could have a material adverse effect on our business, results of operations and cash flows .

Fluctuations in commodity prices and outlook may affect our customers’ investment decisions which may result in existing project cancellations or delays or changes in the timing and funding of new awards.

Demand for many of our services in our commodity-based markets depends on capital spending by oil and natural gas companies, including national and international oil companies, and by industrial companies, which is directly affected by trends in the prices of oil, natural gas and other commodities. Fluctuations in commodity prices can have a direct effect on the profitability and cash flow of such companies, which may impact their willingness to continue pursuing their current investments or make new capital investments. Additionally, commodity prices can also significantly affect the costs of projects. Rising commodity prices can negatively impact the potential returns on investments that are planned, as well as those in progress, and result in customers deferring new investments or canceling or delaying existing projects. To the extent commodity prices decline or fluctuate, or the perceived risk thereof, and our customers defer new investments or cancel or delay existing projects, the demand for our services may decrease, which could have a material impact on our business, financial condition and results of operations.

Risks Related to Financial Conditions and Markets

Current or future economic conditions, including recession or inflation, in credit markets may negatively affect the ability to operate our business, finance working capital, implement our acquisition strategy and access our cash and short-term investments.

We finance our business using cash provided by operations, but also depend on the availability of and access to credit markets, including bank credit lines, letters of credit and surety bonds. Our ability to obtain capital or financing on satisfactory terms will depend in part on prevailing market conditions as well as our operating results. The lack of adequate credit or funding or the unavailability of funding on terms satisfactory to us, could have a material adverse effect on our business and financial performance. Rising or high inflation and/or interest rates could have an adverse effect on our business, financial condition and results of operations. Inflation and rising and/or high interest rates could have a negative impact on our business and we may not be able to fully offset such higher rates.

Disruptions of the capital markets could also adversely affect our clients’ ability to finance projects and could result in contract cancellations or suspensions, project delays and payment delays or defaults by our clients. In addition, clients may be unable to fund new projects, may choose to make fewer capital expenditures or otherwise slow their spending on our services or seek contract terms more favorable to them. Our government clients may face budget deficits that prohibit them from funding proposed and existing projects or that cause them to exercise their right to terminate our contracts with little or no prior notice. Furthermore, any financial difficulties suffered by our subcontractors or suppliers could increase our costs or impact project schedules. These could materially impact our backlog and financial performance.

In addition, we are subject to the risk that the lending counterparties to our Revolver may be unable to meet their contractual obligations to us if they suffer catastrophic demands on their liquidity. We also routinely enter into contracts with counterparties, including vendors, suppliers and subcontractors that may be negatively affected by events in the capital markets. If those counterparties are unable to perform their obligations to us or our clients, we may be required to provide additional services or make alternate arrangements on less favorable terms with other parties to ensure adequate performance and delivery of service to our clients. These circumstances could also lead to disputes and litigation with our partners or clients, which could have a material adverse effect on our reputation, business, financial condition and results of operations.

Furthermore, our cash balances and short-term investments are maintained in accounts held at major banks and financial institutions located primarily in North America, the U.K. and Australia. Deposits are in amounts that exceed available insurance. Although none of the financial institutions in which we hold our cash and investments have gone into bankruptcy, been forced into receivership or have been seized by their governments, there is a risk that this may occur in the future. If this were to occur, we would be at risk of not being able to access our cash and investments, which may result in a temporary decrease in liquidity that could impede our ability to fund operations or execute acquisitions.

We may be unable to obtain new contract awards if we are unable to provide our customers with letters of credit, surety bonds or other credit enhancements.

Customers may require us to provide credit enhancements, including letters of credit, bank guarantees or surety bonds. We are often required to provide performance guarantees to customers to indemnify the customer should we fail to perform our obligations under the contract. Failure to provide the required credit enhancements on terms required by a customer may result

in an inability to bid, win or comply with the contract. Historically, we have had adequate letters of credit capacity but such capacity beyond our Senior Credit Facility is generally at the provider’s sole discretion. Due to events that affect the banking and insurance markets, letters of credit or surety bonds may be difficult to obtain or may only be available at significant cost. Moreover, many projects are very large and complex, which often necessitates the use of a joint venture, often with a market competitor, to bid on and perform the contract. Entering into joint ventures or partnerships exposes us to the credit and performance risk of third parties, many of whom may not be financially as strong or may encounter financial difficulties. If our joint ventures or partners fail to perform, we may be required to complete the project activities. In addition, future projects may require us to obtain letters of credit that extend beyond the term of our Senior Credit Facility. Any inability to bid for or win new contracts due to the of obtaining adequate letters of credit, surety bonds or other customary credit could have a material effect on our business prospects and future revenues.

Our Senior Credit Facility imposes restrictions that limit our operating flexibility and may result in additional expenses, and such facility may not be available if financial covenants are violated or if an event of default occurs.

Our Senior Credit Facility includes a $1 billion revolving credit facility which matures in February 2029, a Term Loan A with debt tranches denominated in U.S. dollars and British pound sterling and a Term Loan B. The Senior Credit Facility contains a number of covenants restricting, among other things, our ability to incur liens and indebtedness, sell assets, repurchase our equity shares and make certain types of investments. We are also subject to certain financial covenants, including but not limited to maintenance of a maximum consolidated net leverage ratio and a consolidated interest coverage ratio as defined in the Senior Credit Facility agreement.

A breach of any covenant or our inability to comply with the required financial ratios could result in a default under our Senior Credit Facility, and we can provide no assurance that we will be able to obtain the necessary waivers or amendments from our lenders to remedy a default. In the event of any default not cured or waived, the lenders are not obligated to provide funding or issue letters of credit and could elect to require us to apply available cash to collateralize any outstanding letters of credit and declare any outstanding borrowings, together with accrued interest and other fees, to be immediately due and payable, thus requiring us to apply available cash to repay any borrowings then outstanding. If we are unable to cash collateralize our letters of credit or repay borrowings with respect to our Senior Credit Facility when due, our lenders could proceed against the guarantees of our major domestic subsidiaries. If any future indebtedness under our Senior Credit Facility is accelerated, we can provide no assurance that our assets would be sufficient to repay such indebtedness in full.

Our indebtedness and the associated covenants could materially adversely affect our ability to obtain additional financing, including for acquisitions and capital expenditures, limit our flexibility to manage our business, prevent us from fulfilling our financial obligations and restrict our use of capital.

We had approximately $2.6 billion of indebtedness outstanding as of January 2, 2026 which could have negative consequences to us, including, but not limited to:

• requiring us to dedicate cash flow from operations to the repayment of debt, interest and other related amounts, which reduces the funds we have available for other purposes, such as working capital, capital expenditures, acquisitions, payment of dividends and share repurchase programs;

• making it more difficult or expensive for us to obtain any necessary future financing for working capital, capital expenditures, debt service requirements, debt refinancing, acquisitions or other purposes;

• reducing our flexibility in planning for or reacting to changes in our industry and market conditions;

• causing us to be more vulnerable in the event of a downturn in our business;

• exposing us to increased interest rate risk given that a portion of our debt obligations are at variable interest rates; and

• increasing our risk of a covenant violation under our Senior Credit Facility.

We may be required to contribute additional cash to meet any unfunded benefit obligations associated with our defined benefit plans.

We have frozen defined benefit pension plans for employees primarily in the U.S., the U.K. and Germany. At January 2, 2026, our defined benefit pension plans had an aggregate funding surplus (calculated as the excess of the fair value of plan assets over the projected benefit obligations) of approximately $85 million. The largest potential source of deficit is related to our defined benefit pension plan in the U.K that is in a funding surplus position at January 2, 2026. In the future, our pension surpluses and deficits may increase or decrease depending on changes in the levels of interest rates, pension plan performance and other factors that may require us to make additional cash contributions to our pension plans and recognize further increases in our net pension cost to satisfy our funding requirements. If we are required or elect to make up all or a significant portion of the deficit for any underfunded benefit plans, our financial position could be materially and affected.

Our U.K. pension plan has been frozen to new participants for a number of years but can still have an aggregate funding deficit due to assumptions and factors noted below. For our frozen defined benefit pension plan in the U.K., the annual minimum funding requirements are based on a binding agreement with the plan trustees that is negotiated on a triennial basis. This agreement also includes other assurances and commitments regarding the business and assets that support the U.K. pension plan. It is possible that, following future valuations of our U.K. pension plan assets and liabilities or following future discussions with the trustees, the annual funding obligation will change. The future valuations under our U.K. pension plan can be affected by a number of assumptions and factors, including legislative changes, assumptions regarding interest rates, inflation, mortality and retirement rates, the investment strategy and performance of the plan assets and (in certain circumstance) actions by the U.K. pensions regulator. Adverse changes in the equity markets, interest rates or actuarial assumptions and legislative or other regulatory actions could increase the risk that the funding requirements increase following the next triennial negotiation. A significant increase in our funding requirements for our U.K. pension plan could result in a material adverse effect on our cash flows and financial position.

We are subject to foreign currency exchange risks that could adversely affect our results of operations and our ability to reinvest earnings from operations. Our ability to mitigate our foreign exchange risk through hedging transactions may be limited.

We generally attempt to denominate our contracts in U.S. dollars or in the currencies of our costs. However, we enter into contracts that subject us to currency risk exposure, primarily when our contract revenues are denominated in a currency different from the contract costs. A portion of our consolidated revenues and consolidated operating expenses are in foreign currencies. As a result, we are subject to foreign currency risks, including risks resulting from changes in currency exchange rates and limitations on our ability to reinvest earnings from operations in one country to fund the financing requirements of our operations in other countries.

The governments of certain countries have or may in the future impose restrictive exchange controls on local currencies and it may not be possible for us to engage in effective hedging transactions to mitigate the risks associated with fluctuations of a particular currency. We are often required to pay all or a portion of our costs associated with a project in the local currency. As a result, we generally attempt to negotiate contract terms with our customer, who is often affiliated with the local government, or has a significant local presence, to provide that we are only paid in the local currency for amounts that match our local expenses. If we are unable to match our local currency costs with revenues in the local currency, we would be exposed to the risk of adverse changes in currency exchange rates.

Risks Related to Our Common Stock

If we need to sell or issue additional shares of common stock to refinance existing debt or to finance future acquisitions or operations, our existing shareholder ownership could be diluted.

Part of our business strategy is to expand into new markets and enhance our position in existing markets, both domestically and internationally, which may include the acquisition and merging of complementary businesses. To successfully fund and complete such potential acquisitions, or to refinance our existing debt, we may issue additional equity securities that may result in dilution of our existing shareholder ownership's earnings per share. For example, we have previously issued convertible notes and may again in the future issue additional convertible notes.

Provisions in our charter documents, Delaware law and our Senior Credit Facility may inhibit a takeover or impact operational control that could adversely affect the value of our common stock.

Our certificate of incorporation and bylaws, as well as Delaware corporate law, contain provisions that could delay or prevent a change of control or changes in our management that a stockholder might consider favorable. These provisions include, among others, prohibiting stockholder action by written consent, advance notice for making nominations at meetings of stockholders, providing for the state of Delaware as the exclusive forum for lawsuits concerning certain corporate matters and the issuance of preferred stock with rights that may be senior to those of our common stock without stockholder approval. These provisions would apply even if a takeover offer may be considered beneficial by some of our stockholders. If a change of control or change in management is delayed or prevented, the market price of our common stock could decline. Additionally, our Senior Credit Facility contains a default provision that is triggered upon a change in control of at least 25%, which would impede a takeover and/or make a takeover more costly.

We may change our dividend policy in the future.

We have maintained a regular cash dividend program since 2007. We anticipate continuing to pay quarterly dividends during fiscal 2026. However, any future payment of dividends, including the timing and amount of any such dividends, is at the discretion of our Board of Directors and may depend upon our earnings, liquidity, financial condition, alternate capital deployment opportunities or any other factors that our Board of Directors considers relevant. A change in our regular cash dividend program could have an adverse effect on the market price of our common stock. In addition, pursuant to a January 7, 2026 Executive Order, the Secretary of War could seek to limit our ability to pay cash dividends or make share repurchases if the Secretary of War determines that we have underperformed or lacked sufficient prioritization of, investment in or production speed in carrying out or performing under our U.S. government contracts.

Risks Related to Regulations, Compliance and Litigation

We could be adversely impacted if we fail to comply with international export and domestic laws, which are rigorously enforced by the U.S. government.

To the extent that we export products, technical data and services outside of the U.S., we are subject to laws and regulations governing trade, exports and sanctions including, but not limited to, the International Traffic in Arms Regulations, the Export Administration Regulations and trade sanctions against embargoed countries, entities and individuals, including sanctions and export restrictions related to Russia's invasion of Ukraine, which are administered by the Office of Foreign Asset Control within the Department of the Treasury. In addition, the U.S. Government has recently announced significant trade policy changes and tariffs. A failure to comply with these laws and regulations could result in civil or criminal penalties or sanctions, including the imposition of fines as well as the denial of export privileges and debarment from participation in U.S. government contracts. U.S. government contract violations could result in the imposition of civil and criminal penalties or sanctions, contract , of profit or of payment, any of which could result in our status as an eligible U.S. government contractor and cause us to reputational , which could have a material effect on our business, financial condition or results of operations.

We are subject to anti-bribery laws in the U.S. and other jurisdictions, violations of which could result in suspension or debarment of our ability to contract with the U.S. state or local governments, U.S. government agencies or the U.K. MoD, third-party claims, loss of customers, adverse financial impact, damage to reputation and adverse consequences on financing for current or future projects.

The FCPA, the U.K. Bribery Act and similar anti-bribery laws in other jurisdictions ("Anti-bribery Laws") generally prohibit companies and their intermediaries from making improper payments to government officials for the purpose of obtaining or retaining business. Our policies mandate compliance with these Anti-bribery Laws. We operate in many parts of the world that have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with Anti-bribery Laws may conflict with local customs and practices. We train our staff concerning Anti-bribery Laws and we also inform our partners, subcontractors, agents and other third parties who work for us or on our behalf that they must comply with the requirements of these Anti-bribery Laws. We also have procedures and controls in place to monitor internal and external compliance. We cannot provide complete assurance that our internal controls and procedures will always protect us from the or acts committed by our employees or third parties working on our behalf. If we are found to be liable for of these laws (either due to our own acts or our inadvertence, or due to the acts or inadvertence of others), we could from or civil or other sanctions, which could have a material effect on our business.

Certain of our work sites are inherently dangerous and we are subject to various environmental and worker health and safety laws and regulations. If we fail to maintain safe work sites or to comply with these laws and regulations, we may suffer damage to our reputation and incur significant costs and penalties that could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Certain work sites often expose our employees and others to chemical and manufacturing processes, highly-regulated materials, large pieces of mechanized equipment and moving vehicles. Additionally, our employees and others at certain project sites may be exposed to severe weather events, austere or remote environments or high security risks. Failure to implement effective safety procedures may result in injury, disability or loss of life to these parties. In addition, the projects may be delayed and we may be exposed to litigation or investigations.

Our operations are subject to a variety of environmental, worker health and safety laws and regulations governing the generation, management and use of regulated materials, the discharge of materials into the environment, the remediation of environmental contamination associated with the release of hazardous substances and human health and safety. Violations of

these laws and regulations can cause significant delays and additional costs to a project. When we perform our services, our personnel and equipment may be exposed to radioactive and hazardous materials and conditions. We may be subject to claims alleging personal injury, property damage or natural resource damages by employees, customers and third parties as a result of alleged exposure to or contamination by hazardous substances. In addition, we may be subject to fines, penalties or other liabilities arising under environmental and employee safety laws. A claim, if not covered by insurance at all or only partially, could have a material adverse impact on our financial condition, results of operations and cash flows. In addition, more stringent regulation of our customers' operations with respect to the protection of the environment could also affect their operations and reduce demand for our services.

Various U.S. federal, state and local as well as foreign environmental laws and regulations may impose liability for property damage and costs of investigation and cleanup of hazardous or toxic substances on property currently or previously owned by us or arising out of our waste management or environmental remediation activities. These laws may impose responsibility and liability without regard to knowledge or causation of the presence of contaminants. The liability under these laws may be joint and several. The ongoing costs of complying with existing environmental laws and regulations could be substantial and have a material adverse impact on our financial condition, results of operations and cash flows. Changes in the environmental laws and regulations, remediation obligations, enforcement actions, stricter interpretations of existing requirements, future discovery of contamination or claims for damages to persons, property, natural resources or the environment could result in material costs and liabilities that we currently do not anticipate.

Our effective tax rate and tax positions may vary.

We are subject to income taxes in the U.S. and numerous foreign jurisdictions. Significant judgment is required in determining certain components of our worldwide provision for income taxes and a change in tax laws, treaties or regulations, or their interpretation, in any country in which we operate could result in higher taxes on our earnings, which could have a material impact on our earnings and cash flows from operations. In the ordinary course of our business, there are certain transactions and calculations where the ultimate tax determination is uncertain. We are audited by various U.S. and foreign tax authorities in the ordinary course of business, and our tax estimates and tax positions could be materially affected by many factors including the final outcome of tax audits and related litigation, the introduction of new tax accounting standards, legislation, regulations and related interpretations, our global mix of earnings, the realizability of deferred tax assets and changes in uncertain tax positions. In particular, international operations could adversely be affected by the OECD’s proposed international taxation reform and introduction of a global minimum tax. A significant increase in tax rates could have a material adverse effect on our profitability and liquidity.

Our business and operations expose us to numerous legal and regulatory requirements, and any violation of these requirements could harm our business.

We are subject to numerous state, federal and international laws and directives and regulations in the U.S. and abroad that involve matters central to our business, including but not limited to, data privacy and security, employment and labor relations, immigration, taxation, anti-corruption, anti-bribery, import-export controls, trade restrictions, internal and disclosure control obligations, securities regulation and anti-competition restrictions. Compliance with legal requirements is costly, time-consuming and requires significant resources. Violations of one or more of these legal requirements in the conduct of our business could result in significant fines and other damages, criminal sanctions against us or our officers, prohibitions on doing business and damage to our reputation. Violations of these regulations or contractual obligations related to regulatory compliance in connection with the performance of customer contracts could also result in liability for significant monetary damages, and , publicity, and other reputational , restrictions on our ability to compete for certain work and by our customers that we have not performed our contractual obligations.

Our failure to comply with the laws and regulations governing OCIs could lead to penalties, including termination of one or more of our U.S. government contracts.

Many of our U.S. government contracts contain OCI clauses that may limit our ability to compete for or perform certain other contracts or other types of services for particular customers. OCI arises when we engage in activities that may make us unable to render impartial assistance or advice to the U.S. government, impair our objectivity in performing contract work, or provide us with an unfair competitive advantage. Existing OCI, and any OCI that may develop, could, if not mitigated to the satisfaction of the customer, preclude our competition for or performance on a significant project or contract, which could limit our opportunities. Further, we occasionally hire former government employees who may be subject to certain representation or non-disclosure obligations. These representation restrictions may, if not honored, result in disqualification from competition or loss of contract, and the violation of such obligations could result in liability for the former government employee. These former government employees may also have had access to competitively sensitive or commercially usable information

that, if not properly firewalled, could result in allegations of unfair competition and, if such findings are made, loss of contract award.

Investigations, audits, claims, disputes, enforcement actions, litigation, arbitration, or other legal proceedings could require us to pay potentially large damage awards or penalties and could be costly to defend, which would adversely affect our cash balances and profitability, and could damage our reputation.

We are subject to and may become a party to various other litigation, claims, investigations, audits, enforcement actions, arbitrations, or other legal proceedings that arise from time to time in the ordinary course of our business. Adverse judgments or settlements in some or all of these legal disputes may result in significant monetary damages, penalties, or injunctive relief against us. Any claims or litigation could be costly to defend, and even if we are successful or fully indemnified or insured, they could damage our reputation and make it more difficult to compete effectively or obtain adequate insurance in the future, and responding to any action may result in a significant of management’s attention and resources. and other are subject to inherent uncertainties and management’s view of these matters may change in the future. For more information, see Note 13. “Commitments and Contingencies” to our consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K.

Risks Related to Climate

There are rapidly evolving views from stakeholders, such as investors, customers and current and future employees, with respect to global climate risks and the related emphasis on sustainability practices, which could affect our business.

Continued attention to issues concerning climate risks or other environmental matters may result in the imposition of additional environmental regulations, rules, standards and policies that seek to restrict, or otherwise impose limitations or costs upon our operations and the emission of greenhouse gases. International agreements, national, regional and state legislation and regulatory measures, including LNG exports, or other policies and restrictions on emissions of greenhouse gases could affect our clients, including those who are involved in the exploration, production or refining of fossil fuels and those who emit greenhouse gases through the combustion of fossil fuels, or through mining, manufacturing or the utilization or production of materials or goods. Such legislation or restrictions could increase the costs of projects for us and our clients or, in some cases, prevent a project from going forward, thereby potentially reducing the need for our services that could in turn have a material adverse effect on our operations and financial condition. However, policy changes and climate legislation could also increase the overall demand for our services as our clients and partners work to comply with such policies, such as by decarbonizing their industries, transitioning from fossil fuels to renewable energy sources and developing integrated and sustainable solutions, which could have a positive impact on our business. We cannot predict when or whether any of these various legislative and regulatory proposals may become law or what their effect will be on us and our customers.

Furthermore, investor and societal expectations with respect to corporate responsibility matters have been rapidly evolving and increasing. We risk damage to our reputation if we do not act responsibly in the following key areas: anti-discrimination, environmental stewardship, support for local communities and corporate governance and transparency. A failure to adequately meet stakeholders' expectations may result in loss of business, diluted market valuation, an inability to attract and retain customers and talented personnel, increased negative investor sentiment toward us and/or our customers and the diversion of investment to other industries, which could have a negative impact on our stock price and our access to and costs of capital. In some cases, certain of our key stakeholders may have oppositional or conflicting views and expectations with respect to various matters (e.g., some may be pro-environmental stewardship and others may be anti-sustainability initiatives). In such cases, it may be or for us to meet all stakeholders’ expectations, and the decisions we make may not yield the results that we expect or intend.

In addition, standards for tracking and reporting corporate responsibility matters continue to evolve. New laws, regulations, policies and international accords relating to such matters, including sustainability, climate-related risks, human capital and anti-discrimination, are being developed and formalized in Europe, the United States, Asia and elsewhere, which may entail specific, target-driven frameworks and/or disclosure requirements. Our selection of voluntary disclosure frameworks and standards, and the interpretation or application of those frameworks and standards, may change from time to time or differ from those of others, and may not be in line with any new and forthcoming related disclosure rules in the United States and abroad. In addition, methodologies for reporting data in these areas (e.g., sustainability and climate-related impacts, or human capital data) may be updated and previously reported data may be adjusted to reflect improvement in availability and quality of internal and third-party data, changing assumptions, changes in the nature and scope of our operations and other changes in circumstances. Our processes and controls for reporting such matters across our operations and supply chain are evolving along with multiple disparate standards for identifying, measuring and reporting metrics, including related disclosures that may be required by the SEC, European and other regulators, and such standards may change over time, which could result in significant

revisions to our current goals, reported progress in achieving such goals or ability to achieve such goals in the future. Any failure, or perceived failure, by us to comply fully with developing interpretations of such laws and regulations could harm our business, reputation, financial condition and operating results and require significant time and resources to make the necessary adjustments. If our corporate responsibility practices do not meet evolving investor or other stakeholder expectations and standards, then our reputation or our attractiveness as an investment, business partner, acquirer, service provider or employer could be negatively impacted.

Climate risks and related environmental issues could have a material adverse impact on our business, financial condition and results of operations.

Climate-related events, such as increased frequency and severity of storms, floods, wildfires, droughts, hurricanes, freezing conditions and other natural disasters, may have a long-term impact on our business, financial condition and results of operations. Although we are proactively seeking measures to mitigate our business risks associated with climate-related events, we recognize that there are innate climate-related risks regardless of where and how we conduct our businesses. As such, a potential disruption to our and our customer's businesses from a natural disaster may cause us to experience work stoppages, project delays, financial losses and additional costs to resume operations such as increased insurance costs or loss of coverage, legal liability and reputational damage.

We may be unable to achieve our sustainability commitments and targets which could result in the loss of investors and customers and damage to our reputation.

We are continuously committed to advancing our sustainability strategy as evidenced by the establishment and continued focus on delivering on our net-zero carbon ambitions after we achieved carbon neutrality in 2019. However, achievement of our sustainability commitments and targets is subject to risks and uncertainties, many of which are outside of our control. These risks and uncertainties include, but are not limited to: our ability to execute our operational strategies and achieve our goals within the currently projected costs and the expected timeframes; the availability and cost of alternative fuels, global electrical charging infrastructure, off-site renewable energy and other materials and components; unforeseen design, operational and technological difficulties; the outcome of research efforts and future technology developments, including the ability to scale projects and technologies on a commercially competitive basis such as carbon sequestration and/or other related processes; compliance with, and changes or additions to, global and regional regulations, taxes, charges, mandates or requirements relating to greenhouse gas emissions, carbon costs or climate-related goals; labor-related regulations and requirements that restrict or prohibit our ability to impose requirements on third party contractors; adapting products to customer preferences and customer acceptance of sustainable supply chain solutions; the actions of competitors and competitive pressures; and an acquisition of or merger with another company that has not adopted similar carbon goals or whose towards reaching its carbon goals is not as advanced as ours.

Although we believe that our sustainability commitments and targets are achievable, there is no assurance that we will be able to successfully implement our strategies and achieve our net-zero targets. Investors have recently increased their focus on sustainability matters, including practices related to greenhouse gas emissions and the environment. Additionally, an increasing percentage of the investment community considers sustainability factors in making investment decisions, and an increasing number of entities are considering sustainability factors in awarding business. The implementation of these goals and initiatives may require considerable investments, and our goals, with all of their contingencies, dependencies and in certain cases, reliance on third-party verification and/or performance, are complex and ambitious and may change, and we cannot guarantee that we will achieve them. If we are unable to meet our commitments and targets and appropriately address sustainability enhancement, we may lose investors, customers or partners, our stock price may be negatively impacted, our reputation may be negatively affected and it may be more for us to compete effectively, all of which could have an effect on our business, results of operations and financial condition, as well as on the price of our common stock.

Forward-Looking and Cautionary Statements

This Annual Report on Form 10-K contains certain statements that are, or may be deemed to be, "forward-looking statements" within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. The Private Securities Litigation Reform Act of 1995 provides safe harbor provisions for forward-looking information. Some of the statements contained in this Annual Report on Form 10-K are forward-looking statements. All statements other than statements of historical fact are, or may be deemed to be, forward-looking statements. The words "believe," "may," "estimate," "continue," "anticipate," "intend," "plan," "expect" and similar expressions are intended to identify forward-looking statements. Forward-looking statements include information concerning our possible or assumed future financial performance and results of operations, and include information related to the proposed spin-off of our Mission Technology Solutions business into a stand-alone, publicly traded company.

We have based these statements on our assumptions and analyses in light of our experience and perception of historical trends, current conditions, expected future developments and other factors we believe are appropriate in the circumstances. Forward-looking statements by their nature involve substantial risks and uncertainties that could significantly affect expected results, and actual future results could differ materially from those described in such statements. While it is not possible to identify all factors, factors that could cause actual future results to differ materially include the risks and uncertainties disclosed under “Item 1A. Risk Factors” contained in Part I and other relevant sections of this Annual Report on Form 10-K.

Many of these factors are beyond our ability to control or predict. Any of the following factors, as well as the risks and uncertainties disclosed under “Item 1A. Risk Factors” contained in Part I of this Annual Report on Form 10-K, and the risk factors and other cautionary statements contained in our other filings with the SEC, or a combination of these factors, could materially and adversely affect our future financial condition or results of operations and the ultimate accuracy of the forward-looking statements. These forward-looking statements are not guarantees of our future performance, and our actual results and future developments may differ materially and adversely from those projected in the forward-looking statements. We caution against putting undue reliance on forward-looking statements or projecting any future results based on such statements or on present or prior earnings levels. In addition, each forward-looking statement speaks only as of the date of the particular statement, and we undertake no obligation to publicly update or revise any forward-looking statement.

Summary Risk Factors

The following is a summary of some of the risks and uncertainties that could materially adversely affect our business, financial condition and results of operations. This summary should be read together with the more detailed description of each risk factor disclosed under "Item 1A. Risk Factors" contained in Part I of this Annual Report on Form 10-K.

Risks Related to Operations of Our Business

• Any loss, cancellation or delay in one or more projects by our significant customers in the future could negatively affect our financial performance.

• Our results of operations and cash flows depend on the award of new contracts and the timing of the performance of existing contracts.

• Ongoing international conflicts may adversely affect our business and results of operations.

• If there are any successful intellectual property infringement proceedings against us, our competitive position could be adversely impacted.

• Uncertainty over global tariffs may negatively impact our business and results of operations.

• We may not properly leverage or appropriately invest in technology advancements, which could result in the potential loss of market share and profits.

• We may use artificial intelligence, machine learning, data science and similar technologies in our business, and challenges with properly managing such technologies could result in reputational harm, competitive harm, and legal liability, and adversely affect our business, financial condition and results of operations.

• If we are unable to attract and retain senior management and key technical professionals with appropriate government qualifications, our ability to pursue and compete for projects to grow our business may be adversely affected.

• The nature of our business exposes us to potential liability claims and contract disputes that may exceed or be excluded from existing insurance coverage.

• Dependence on third-party subcontractors, suppliers and equipment manufacturers could adversely affect our financial performance on contracts.

• Employee, agent or partner misconduct, or our overall failure to comply with laws or regulations, could weaken our ability to win contracts, which could result in reduced revenues and profits.

• We depend on our teaming arrangements and relationships with other contractors and subcontractors. If we are not able to maintain these relationships, or if these parties fail to satisfy their obligations to us or the customer, our business, financial condition and results of operations could be adversely affected.

• We use estimates in recognizing revenues, and if we make changes to estimates used in recognizing revenues, our profitability may be adversely affected.

• We conduct a portion of our operations through joint ventures and partnerships, which exposes us to risks and uncertainties, many of which are outside of our control.

• The nature of our contracts subjects us to risks associated with cost overruns, operating cost inflation and potential claims for liquidated damages.

• Our backlog of unfilled orders is subject to unexpected adjustments and cancellations.

• We have made and may continue to make business combinations, which may present certain risks and uncertainties.

• International and political events may adversely affect our operations.

• Internal or external cybersecurity or privacy breaches, or systems and information technology interruption or failure could adversely impact our ability to operate or expose us to significant financial losses and reputational harm.

• Global pandemics, epidemics, outbreaks of infectious diseases or public health crises have disrupted our business and could have a material adverse effect on our future results of operations and financial performance.

• An impairment of all or part of our goodwill or our intangible assets could have a material adverse impact on our net earnings and net worth.

• Our actual results could differ from the estimates and assumptions used to prepare our financial statements.

• We ship a significant amount of cargo using seagoing vessels, exposing us to certain maritime risks.

Risks Related to the Planned Spin-Off of Mission Technology Solutions

• We are subject to risks related to our plan to spin off our Mission Technology Solutions business into a standalone, publicly traded company.

• Following the Planned Spin-Off, we and the spun-off Mission Technology Solutions business may face stranded costs, loss of economies of scale, and higher operating expenses than currently anticipated, which could materially adversely affect our profitability.

• Our operations may be significantly disrupted during and following the Planned Spin-Off process, and we will be dependent on the spun-off entity’s performance under various transition agreements, the failure of which could materially harm our business.

Risks Related to Our Industry

• The U.S. government awards its contracts through a rigorous competitive process and our efforts to obtain future contracts may be unsuccessful.

• Our profitability and cash flow may vary based on the mix of our contracts and programs, our performance and our ability to control costs.

• The U.S. government may issue or revise existing rules, regulations and directives, adopt new contract rules and regulations or revise its procurement practices in a manner adverse to us at any time.

Our Business Segments

We provide a wide range of professional services, and the management of our business is heavily focused on major projects or programs within each of our reportable segments. At any given time, government programs and joint ventures represent a substantial part of our operations.

Our business is organized into two core business segments and one non-core business segment as follows:

Core business segments

• Mission Technology Solutions

• Sustainable Technology Solutions

Non-core business segment

• Corporate

Our business segments are described below.

Mission Technology Solutions. Our Mission Technology Solutions business segment provides full life-cycle support solutions to defense, intelligence, space, aviation and other programs and missions for military and other government agencies primarily in the U.S., U.K. and Australia. KBR's full-spectrum solutions span research and development, advanced prototyping, acquisition support, systems engineering, C5ISR, cyber analytics, space domain awareness, test and evaluation, data analytics and integration, systems integration and program management, global supply chain management, operations readiness and support and professional advisory services across the defense, energy security and transition and critical infrastructure sectors. Included in Mission Technology Solutions is the business of LinQuest Corporation ("LinQuest"), an engineering, data analytics and digital integration company acquired in fiscal 2024 and Infrastar Limited acquired in fiscal 2025. See Note 4. "Acquisitions" to our consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K for additional information on these acquisitions. Additionally, the disposal of HomeSafe is reported as discontinued operations and HomeSafe's operations are excluded from Mission Technology Solutions results reflected within our consolidated financial statements. See Note 21. “Discontinued Operations” to our consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K for additional information regarding the HomeSafe disposal.

Sustainable Technology Solutions. Our Sustainable Technology Solutions business segment is anchored by our portfolio of over 85 innovative, proprietary, sustainability-focused process technologies that reduce emissions, increase efficiency and/or accelerate and enable energy transition across the industrial base in four primary verticals: ammonia/syngas, chemical/petrochemicals, clean refining and circular process/circular economy solutions. STS also provides highly synergistic services including advisory and consulting focused on energy security, broad-based energy transition and net-zero carbon emission solutions, high-end engineering, design and program management centered around decarbonization, energy efficiency, environmental impact and asset optimization, as well as our digitally-enabled operating and monitoring solutions. Through early planning and scope definition, advanced technologies and facility life-cycle optimization, our STS business segment works closely with customers to provide what we believe is the optimal approach to maximize their return on investment.

Corporate. Our non-core segment includes corporate expenses and selling, general and administrative expenses not allocated to the business segments above.

To streamline and optimize our processes, we realigned our segments effective for the year ended January 2, 2026. As part of this realignment, our Government Solutions reportable segment has been renamed Mission Technology Solutions while Sustainable Technology Solutions has retained its name. The international business contained within Government Solutions has been integrated into both Mission Technology Solutions and Sustainable Technology Solutions. All information in this Annual Report on Form 10-K is presented in accordance with the realigned reportable segments and all prior period information was recast to reflect the realigned reportable segments. Effective for fiscal year 2026, a portion of a business unit within our Mission Technology Solutions segment will become part of our Sustainable Technology Solutions segment. We will begin reporting new segment information due to this change beginning the first fiscal quarter of 2026.

Mission Technology Solutions Spin-off

In September 2025, we announced our intention to spin off our Mission Technology Solutions business into a separate, U.S. publicly-traded company (the "Planned Spin-Off"). The Planned Spin-Off is intended to be tax-free to us and our shareholders for U.S. federal income tax purposes and targeting completion in the second half of the fiscal year ended January 1, 2027 ("fiscal 2026"). The spin-off will be subject to final approval by our Board of Directors and other customary conditions, including receipt of a favorable opinion of legal counsel and/or a private letter ruling from the U.S. Internal Revenue Service with respect to the tax treatment of the transaction for U.S. federal income tax purposes, the effectiveness of a registration statement on Form 10 filed with the SEC, satisfactory completion of financing and other regulatory approvals. Because the intended transaction is a spin-off, the Mission Technology Solutions business is not classified as held for sale and will be reported as continuing operations.

Significant Customers

We provide services and technology to a diverse customer base, including domestic and foreign governments and commercial and industrial companies.

We generate significant revenues within our MTS business segment from key U.S. government customers including U.S. DoW agencies such as the U.S. Army, Navy, Air Force, Space Force, Missile Defense Agency, National Geospatial-Intelligence Agency, National Reconnaissance Office and other intelligence agencies; U.S. civilian agencies such as NASA, U.S. Geological Survey and National Oceanic and Atmospheric Administration; and from the U.K government. No other customers represented 10% or more of consolidated revenues in any of the periods presented. The following table summarizes our revenues from contracts with U.S. and U.K. government agencies for which we are the prime contractor, as well as for those contracts in which we are a subcontractor and the ultimate customer is a U.S. or U.K. government agency, respectively.

Significant Joint Ventures and Alliances

We enter into joint ventures and alliances with other industry participants to capitalize on the strengths of each party, provide greater flexibility in delivering our services based on expertise, cost and geographical efficiency, increase the number of opportunities that can be pursued, reduce exposure and diversify risk. Our significant joint ventures and alliances are described below. All joint venture ownership percentages presented are stated as of January 2, 2026.

Aspire Defence Limited, a joint venture owned by KBR and two financial investors, provides a range of facilities life cycle management services at the British Army’s garrisons at Aldershot and across the Salisbury Plain in the U.K. KBR owns 45% of Aspire Defence Limited, which is a VIE, that is reported within our MTS business segment using the equity method of accounting.

The Affinity joint venture, with Elbit Systems Ltd., procures, operates and maintains aircraft and aircraft-related assets over an 18-year contract period, in support of the U.K. MFTS project. KBR owns a 50% interest in Affinity. In addition, KBR owns a 50% interest in the two joint ventures, Affinity Capital Works and Affinity Flying Services, which provide procurement, operations and management support services under subcontracts with Affinity. The project-related entities are VIEs and the investments are accounted for within our MTS business segment using the equity method of accounting.

Brown & Root Industrial Services is a joint venture with One Equity Partners and offers maintenance services, turnarounds and small capital projects, primarily in North America, in which we own 50% equity interest. The investment is accounted for within our STS business segment using the equity method of accounting and we have determined that the joint venture is not a VIE.

JKC Australia LNG is a joint venture contracted to perform the engineering, procurement, supply, construction and commissioning of onshore LNG facilities for a client in Darwin, Australia. The project is being executed through two entities (collectively, "JKC"), which are VIEs, in which we own a 30% equity interest. The investment is accounted for within our STS business segment using the equity method of accounting.

KZJV is a joint venture with Zachry Group that performs certain design, engineering, procurement and construction-related services for a LNG facility in Plaquemines Parish, Louisiana. KBR owns a 45% interest in KZJV, which is a VIE. The investment is accounted for within our STS business segment using the equity method of accounting.

HomeSafe, a joint venture with Tier One Relocation, was established to be the exclusive provider of household goods move management services for the U.S. Armed Forces, U.S. DoW civilians and their families. HomeSafe informed us on June 18, 2025, that U.S. Transportation Command unexpectedly terminated HomeSafe's role in the Global Household Goods Contract. KBR owns a 72% interest in HomeSafe. The HomeSafe joint venture is a VIE that is consolidated for financial reporting purposes. As of January 2, 2026 all of HomeSafe's operations, including run-off operations, have ceased. We disposed of HomeSafe in the second quarter of fiscal 2025 and determined that this disposal met the requirements to be reported as discontinued operations. As such, the results of HomeSafe are presented as discontinued operations within this Annual Report on Form 10-K. HomeSafe was previously reported within our MTS business segment.

Additional information relating to our joint ventures is described in Part II, Item 8 of this Annual Report on Form 10-K in Note 9. "Equity Method Investments and Variable Interest Entities" to our consolidated financial statements.

Backlog of Unfulfilled Orders

Backlog is our estimate of the U.S. dollar amount of future revenues we expect to realize as a result of performing work on awarded contracts. For projects within our unconsolidated joint ventures, we have included our percentage ownership of the joint venture’s estimated revenues in backlog to provide an indication of future work to be performed. The future revenues we expect to realize in backlog were $16,864 million and $16,605 million as of January 2, 2026 and January 3, 2025, respectively, with approximately 17% related to work being executed by joint ventures accounted for using the equity method of accounting. We estimate as of January 2, 2026, 36% of our backlog will be recognized as revenues or equity in earnings of unconsolidated affiliates within fiscal year 2026. For additional information regarding backlog, see our discussion within “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in Part II of this Annual Report on Form 10-K.

Government Contracts and Regulations

Our business is heavily regulated. We contract with numerous U.S. government agencies and entities, principally the U.S. DoW, NASA and certain intelligence agencies. When working with these and other U.S. government agencies and entities, we must comply with various laws and regulations relating to the formation, administration and performance of contracts. U.S. government contracts are generally subject to the FAR, which sets forth policies, procedures and requirements for the acquisition of goods and services by the U.S. government, other agency-specific regulations that implement or supplement the FAR, such as the DoW FAR Supplement and other applicable laws and regulations. These regulations impose a broad range of requirements, many of which are unique to government contracting, including various procurement, import and export, security, contract pricing and cost, contract termination and adjustment and audit requirements. Among other things, these laws and regulations:

• require certification and disclosure of all cost and pricing data in connection with certain contract negotiations;

• define allowable and unallowable costs and otherwise govern our right to reimbursement under various cost-type U.S. government contracts;

• require compliance with CAS;

• require reviews by the DCAA, DCMA and other regulatory agencies for compliance with a contractor’s business systems;

• restrict the use and dissemination of and require the protection of unclassified contract-related information and information classified for national security purposes and the export of certain products and technical data; and

• prohibit competing for work if an actual or potential organizational conflict of interest, as defined by these laws and regulations, related to such work exists and/or cannot be appropriately mitigated, neutralized or avoided.

Our MTS business in the U.S. primarily performs work under cost-reimbursable contracts with the DoW and other U.S. governmental agencies. If the U.S. government concludes costs charged to a contract are not reimbursable under the terms of the contract or applicable procurement regulations, these costs are disallowed or, if already reimbursed, we may be required to

refund the reimbursed amounts to the customer. Such conditions may also include interest and other financial penalties. If performance issues arise under any of our government contracts, the customer retains the right to pursue remedies, which could include termination under any affected contract. Generally, our customers have the contractual right to terminate or reduce the amount of work under our contracts at any time. For more information, see “Item 1A. Risk Factors” contained in Part I of this Annual Report on Form 10-K.

Our MTS business also participates in PFI contracts, such as the Aspire Defence and U.K. MFTS projects. PFIs are long-term contracts that outsource the responsibility for the construction, procurement, financing, operation and maintenance of government-owned assets to the private sector. These PFI contracts predominately contain fixed-price elements. The PFI projects in which KBR participates are all located in the U.K. with contractual terms ranging from 15 to 35 years and involve the provision of services to various types of assets ranging from acquisition and maintenance of major military equipment and housing to transportation infrastructure. Under most of these PFI contracts, the primary deliverables of the contracting entity are the initial construction or procurement of assets for the customer and the subsequent provision of lifecycle management services for the life of such assets. The amount of renumeration from the customer to the contracting entity is negotiated on each contract and varies depending on the specific terms for each PFI.

Contract Types

The Company performs work under contracts that broadly consist of fixed-price, cost-reimbursable, time-and-materials or a combination of the three.

Under fixed-price contracts , we perform a defined scope of work for a specified fee to cover all costs and any profit element. Fixed-price contracts entail risk to us because they require us to predetermine the work to be performed, the project execution schedule and all the costs associated with the scope of work. Additionally, unit-rate contracts are considered fixed-price contracts with the only variable being units of work to be performed. Further, our fixed-price contracts may include cost escalation and other features that allow for increases in price should certain events occur or conditions change. Fixed-price contracts are typically subject to change orders if the scope of work changes or unforeseen conditions arise resulting in adjustments to the fixed price. Although fixed-price contracts involve greater risk than cost-reimbursable contracts, they also are potentially more profitable because the owner/customer pays a premium to transfer project risks to us.

Time-and-materials contracts typically provide for negotiated fixed hourly rates for specified categories of direct labor. The rates cover the cost of direct labor, indirect expense and fee. These contracts can also allow for reimbursement of cost of material plus a fee, if applicable. In U.S. government contracting, this type of contract is generally used when there is uncertainty of the extent or duration of the work to be performed by the contractor at the time of contract award or it is not possible to anticipate costs with any reasonable degree of confidence. With respect to time-and-materials contracts, we assume the price risk because our costs of performance may exceed negotiated hourly rates. In commercial and non-U.S. government contracting, this contract is generally used for defined and non-defined scope contracts where there is a higher degree of uncertainty and risks of work. These types of contracts may also provide for a guaranteed maximum price where the total cost plus the fee cannot exceed an agreed upon guaranteed maximum price or not-to-exceed provisions.

Under cost-reimbursable contracts , the price is generally variable based upon our actual allowable costs incurred for materials, equipment, reimbursable labor hours, overhead and G&A expenses. Profit on cost-reimbursable contracts may be in the form of a fixed fee or a mark-up applied to costs incurred, or a combination of the two. The fee may also be an incentive fee based on performance indicators, milestones or targets and can be based on customer discretion or in the form of an award fee determined based on customer evaluation of the Company's performance against contractual criteria. Cost-reimbursable contracts may also provide for a guaranteed maximum price where the total fee plus the total cost cannot exceed an agreed upon guaranteed maximum price. Cost-reimbursable contracts are generally less risky because the owner/customer retains many of the project risks, however it generally requires us to use our best efforts to accomplish the scope of the work within a specified time and budget. Cost-reimbursable contracts with the U.S. government are generally subject to the FAR and are competitively priced based on estimated or actual costs of providing the contractual goods or services. The FAR provides guidance on types of costs that are allowable in establishing prices for goods and services provided to the U.S. government and its agencies. Pricing for non-U.S. government agencies and commercial customers is based on specific negotiations with each customer.

Raw Materials and Suppliers

Equipment and materials essential to our business are obtained from a variety of global sources. The principal equipment and materials we use in our business are subject to availability and price fluctuations due to customer demand, producer capacity and market conditions. We monitor the availability and price of equipment and materials on a regular basis. Our procurement function seeks to leverage our size and buying power to ensure that we have access to key equipment and materials at low prices and ideal delivery schedules. We purchase our required materials and equipment from a variety of sources. We have not experienced, and do not anticipate experiencing, any significant procurement difficulties as a result of political and economic conditions and regional conflict and war that have resulted in significant supply chain disruptions and inflation globally and within the United States. However, a number of factors that we may not be able to predict or control could result in increased costs for materials as well as global trade relationships, regional conflict and wars and other general market and political conditions. These potential increased costs could reduce profitability on our contracts, particularly those that are fixed price. See “Item 1A. Risk Factors” contained in Part I of this Annual Report on Form 10-K for more information.

Intellectual Property

The use of intellectual property generally benefits our STS business segment. We have developed, acquired or otherwise have the right to license leading technologies, including technologies held under license from third parties, used for the production of a range of essential products in the areas of transportation fuels, petrochemicals and polymers, fertilizers, semi-submersibles and specialty chemicals. The technologies we license include the transformation of raw materials into commodity chemicals, such as phenol, which is used in the production of consumer end products and our ammonia process technologies used in the conversion of natural gas to ammonia with a fully developed, proprietary, end-to-end solutions for both fossil-based and green ammonia (K-GreeN TM ) . We are the exclusive licensor of Hydro-PRT TM , a cutting-edge, scalable technology that utilizes supercritical water to convert a wide range of single-use and other waste plastics into commercial raw materials used to produce new plastics, a circular solution and our Sustainable Aviation Fuel technology (PureSAF SM ) extends our decarbonization efforts into the aviation sector. We also offer technologies for conversion and refinement of minerals that are necessary for electrification of a range of industries. We believe our technology portfolio and experience in the commercial application of these technologies and our related know-how differentiates us, enables our sustainability strategy and enhances our margins.

Our rights to make use of technologies licensed to us are governed by written agreements of varying durations, including some with fixed terms that are subject to renewal based on mutual agreement. Generally, each agreement may be further extended and we have historically been able to renew existing agreements before they expire. The same agreements are supportive of the expansion of the third party partner's relevant intellectual property portfolio to the mutual benefit of both parties. We expect these and other similar agreements to be extended so long as it is mutually advantageous to both parties at the time of renewal. For technologies we own, we protect our rights, know-how and trade secrets through patents and confidentiality agreements.

Seasonality

Our operations are not generally affected by seasonality. However, various factors can affect the distribution of our sales between accounting periods, including the timing of government awards, the availability of government funding, product deliveries and customer acceptance. Additionally, weather and natural phenomena can temporarily affect the performance of our services.

Environmental Regulation

Our business involves design, management, operations and maintenance at various project sites throughout the world, which may be in and around sensitive environmental areas, such as rivers, lakes and wetlands. Our operations may require us to manage, handle, transport and dispose of toxic or hazardous substances, which are subject to stringent and complex laws relating to environmental protection.

Significant fines, penalties and other sanctions may be imposed for non-compliance with environmental and worker health and safety laws and regulations, and some laws provide for joint and several strict liabilities for remediation of releases of hazardous substances, rendering a person liable for environmental damage, without regard to negligence or fault on the part of such person. These laws and regulations may expose us to liability arising out of the conduct of operations or conditions caused by others, or for our acts that were in compliance with all applicable laws at the time these acts were performed. For

example, there are a number of governmental laws that strictly regulate the handling, removal, treatment, transportation and disposal of toxic and hazardous substances, such as the Comprehensive Environmental Response Compensation and Liability Act of 1980, and comparable national and state laws that impose strict, joint and several liabilities for the entire cost of cleanup, without regard to whether a company knew of or caused the release of hazardous substances. In addition, some environmental regulations can impose liability for the entire clean-up costs on owners, operators, transporters and other persons arranging for the treatment or disposal of such hazardous substances related to contaminated facilities or project sites. Other environmental laws applicable to our and customers' operations affecting us include, but are not limited to, the Resource Conservation and Recovery Act, the National Environmental Policy Act, the Clean Air Act, the Clean Water Act, the Occupational Safety and Health Act and the Toxic Substances Control Act as well as other comparable foreign and state laws. Liabilities related to environmental contamination or human exposure to hazardous substances or a failure to comply with any applicable environmental and worker health and safety laws and regulations could result in substantial costs to us, including cleanup costs, , civil or sanctions, third-party for property , personal or cessation of remediation activities.

Additional information relating to environmental regulations is described in "Item 1A. Risk Factors” contained in Part I of this Annual Report on Form 10-K.

In addition, our unconsolidated joint ventures employ approximately 9,000 employees.

Our Employee Value Proposition ("EVP") is the unique set of experiences and offerings that help differentiate KBR from other competitors for our employees’ time and talents and describes in practical terms how we put our people first.

Purpose & Values

At the center of our EVP is Purpose, because at KBR, we do work that matters, helping to solve the great challenges of our time while striving to create a secure, safer and more sustainable world. Our vision is to bring together the best and brightest employees to deliver technology and solutions that help our customers accomplish their most critical missions and objectives, and this important work enables us to attract and retain some of the world’s best talent, who thrive in this purposeful environment.

Our Values unite us across global cultures, guiding our behavior and decision making throughout KBR. We have embedded our values in our business processes, established them as a foundation for our learning and development activities and regularly celebrate employees who epitomize our values-led behavior. While our One KBR Values unite us, as a global business operating in distinct markets and environments, we recognize and respect that our cultures are different. Acknowledging these differences, our ethos weaves a golden thread through KBR. Our employees take enormous pride in being part of an organization with a philosophical, practical and proven commitment to fostering an environment in which our people can belong, connect and grow.

Health and Safety

We are subject to numerous worker health and safety laws and regulations across the globe. Our commitment to the health and safety of each employee as well as anyone we work with is the foundation of our Zero Harm culture. We know that our employees’ willingness to implement each commitment into their daily work tasks is vital to our operations and has contributed to our industry-leading safety performance among our customers, partners and peers.

The six core processes that comprise our Transactional Health, Safety, Security, Environmental ("HSSE") Management that lead to Transformational Leadership are non-negotiable KBR safety standards that are required to be observed and followed by employees and contractors at all locations and projects. By requiring our employees to personally internalize and adhere to these standards, we aim to safeguard our individual health and safety and the well-being of all those around us.

We provide the tools our people need to achieve the mindset of 24/7 Zero Harm such as our Courage to Care Conversation program, which is instrumental in developing a continual awareness of unsafe acts through observation, intervention and conversation. The goal of the Courage to Care Conversation is to continuously evaluate the work environment and to focus on people and their actions.

Thanks to our people's commitment to our Zero Harm culture, we recorded another consecutive year of industry-leading HSSE performance, with a total recordable incident rate of 0.033.

Our Journey to Zero Harm has allowed us to create a company culture where safe execution is non-negotiable and people take responsibility and accountability. When it comes to safety, we strive for one number: Zero.

Ethics and Compliance

KBR's ethics and our Code of Business Conduct (the “Code”) are rooted in our values and provide the standards and support to help us successfully navigate issues, make the right decisions, and conduct our business with the integrity that reflects our heritage and ethical reputation. Additionally, our Code is essential to how we as a Team of Teams interact with the world around us and to our success.

We believe that an ethical culture, where employees are treated fairly, respectfully and without favoritism, is key to employee satisfaction and retention. We promote a speak-up culture where employees are comfortable making reports of possible unethical behavior and workplace issues. The Business Integrity Team provides an easy to access Ethics Hotline and numerous other channels for employees to receive advice, confidentially or anonymously, on ethical or other inquiries. Employees speaking up and reporting issues enable us to address and remediate these issues early and effectively while instilling confidence that employee concerns are heard and addressed.

Retaliation undermines a speak-up culture and is not tolerated. Our Code and our Business Integrity program set forth our anti-retaliation commitment, which is reinforced in our communications and our annual Ethics training. To further convey to the workforce that reports of unethical behavior are investigated and remediated, the Ethics training incorporates examples of past misconduct incidents.

Career

As well as providing meaningful work from day one, our employees and job applicants are attracted to KBR because of the opportunity to develop personally and reach their full potential. Providing the opportunity to ‘Grow’ at KBR is a key component in our EVP. We have a good reputation among our employees for providing growth opportunities and have continued to focus on enhancing these growth prospects in several ways throughout fiscal 2025 with the introduction of formal mentoring and sponsorship programs, skills for the future offerings and an internal career pathways forum. In addition, we invest in training our employees across a range of topics that align with and enhance our values, including programs that focus on leadership, ethics and technical development.

Technical Professionals

For our Technical Talent, our One KBR Tech Fellows program provides funding and opportunities for these world-leading scientists and technical professionals to conduct advanced research into topics ranging from carbon capture to machine learning. Our Fellows also provide valuable input into strategy development, business development and talent development within KBR. Understanding the importance of internal advancement for attracting and retaining top technical talent, we introduced the Career Opportunities Technical Talent Guide to outline technical career growth through roadmaps, expectations for each career journey stages and resources and tools. KBR Communities of Interest ("COIs") are also designed to foster technical development by providing collaborative, virtual forums for subject matter experts and those who support them. Our COIs continue to evolve, ensuring that subject matter experts across the globe can connect and collaborate on Data Science and Digital Technologies, Sustainability and Energy Transition, Human Performance and other technical specialties that inform our customers’ and society’s greatest challenges today.

Leadership

Our flagship leadership program, the Global Leadership Development Program, is expanding to go beyond training to develop capabilities in being effective future executive leaders. As well as developing strategic thinking through research

projects ranging from sustainability investments to digital supply chain solutions, these leaders attend intense learning events focused on executive skills and leading courageously and with integrity. The course cultivates peer networks, sharpens enterprise mindsets and builds commercial and strategy acumen. We also strengthen our future leadership by running regular Manager Excellence Programs, and in 2025 our Front-Line Leaders Program supported over 600 employees globally who were newly transitioning into these critical leadership roles.

Talent Development & Succession Planning

In fiscal 2025, our Talent Calibration conversations covered nearly 6,000 KBR employees in a rigorous assessment of performance and potential. As well as providing organization-wide talent trends and data, these conversations lead to individual career plans and added rigor to our succession plans. The Board Nominations & Corporate Governance Committee received regular updates on this process throughout the year, where detailed discussions on updated succession plans for the CEO and Executive Leadership Team take place.

Performance Management

Our agile approach to performance management continued successfully into fiscal 2025 where we focused on frequent Check-in Conversations about performance, career development, and priority alignment between managers and their team members. Our employees indicated in surveys that they prefer this approach and we view it as more inclusive, engaging, agile and supportive of a high-performing culture. In fiscal 2025, we continued to embed the Agile Performance & Development process across KBR and strengthen capabilities for holding quality, effective Check-ins.

Total Reward

Throughout fiscal 2025, we continued to benchmark pay and benefits in local markets and expand our offerings to help us attract and retain the best and brightest talent.

Talent Acquisition

Our Talent Acquisition strategy aligns recruitment efforts with broader business objectives. This unified approach ensures consistency across regions while empowering teams to tailor strategies to their local markets. Our cross-border collaboration and global teams help with consistency, adoption of best practices and scalability. These efforts strengthen internal mobility, build future-focused talent pipelines and enhance our ability to meet hiring demands effectively. Our Applicant Tracking System and Customer Relationship System platforms streamline workflows for candidates, hiring managers and recruiters, and improve training and standardization.

As a result, we hired over 5,900 employees in fiscal 2025, supporting our ability to deliver excellent solutions for our customers and meet our strategic growth targets.

Item 1A. Risk Factors

Risks Related to Operations of Our Business

A considerable percentage of our revenues, particularly in our MTS business segment, is generated under contracts with certain significant customers. Revenues from the U.S. government represented 57% of our total consolidated revenues for fiscal 2025. Budget uncertainty, the potential for U.S. government shutdowns, the use of continuing resolutions and the federal debt ceiling can adversely affect our industry and the funding for our contracts. In addition, government acquisition reform and spending cut initiatives, including executive orders, may impact our business. For example, on January 20, 2025, an executive order was signed to create an advisory commission, DOGE, to reform federal government processes and reduce expenditures. Although DOGE was disbanded in November 2025, we cannot rule out the possibility of similar initiatives occurring in the future. Further, on April 15, 2025, Executive Order 14275, “Restoring Common Sense to Federal Procurement,” was signed, directing major revisions to the FAR to make the government’s procurement process more efficient, and on November 7, 2025, the U.S. DoW released a memorandum and strategy on defense acquisition reform titled “Transforming the Warfighting Acquisition System” that aims to overhaul the procurement landscape and prioritizes speed to capability delivery. If appropriations are delayed, a government shutdown were to occur and continue for an extended period of time, or changes in budgetary priorities or U.S. government spending levels were to occur, we could be at risk of contract , contract options not being exercised, funding , , increased uncertainty in the conversion of our book to bill to revenue and other and nonrepayment. When the U.S. government operates under a continuing resolution, new contract starts are restricted and funding for our programs may be , reduced or . Shifting funding priorities or federal budget compromises also could result in reductions in overall defense spending on an absolute or inflation-adjusted basis, which could affect our business, financial performance and condition. In addition, if we are to effectively respond to proposed acquisition reform in the U.S., our ability to secure and perform government contracts could be affected, which may impact our business, financial condition and results of operations. If we are deemed to be on our contracts, our business, financial condition and results of operations may likewise be impacted.
