The accompanying consolidated financial statements have been prepared in accordance with U.S. GAAP and include the accounts of KBR, Inc. and the subsidiaries it controls, including VIEs where it is the primary beneficiary. We account for investments over which we have significant influence, but not a controlling financial interest, using the equity method of accounting. See Note 9. "Equity Method Investments and Variable Interest Entities" to our consolidated financial statements for further discussion of our equity investments and VIEs. All material intercompany balances and transactions are eliminated in consolidation. Certain amounts in prior periods have been reclassified to conform with current period presentation. We have evaluated all events and transactions occurring after the balance sheet date but before the consolidated financial statements were issued and have included the appropriate disclosures.

As discussed further in Note 21. “Discontinued Operations” to our consolidated financial statements, HomeSafe informed us on June 18, 2025, that U.S. Transportation Command unexpectedly terminated HomeSafe’s role in the Global Household Goods Contract. 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 in the accompanying consolidated statements of operations, consolidated balance sheets and consolidated statements of cash flows and notes for all periods presented.

In 2022, the Board of Directors approved a change in the fiscal year end from a calendar year ending on December 31 to a 52 – 53 week year ending on the Friday closest to December 31, effective as of the commencement of the Company's fiscal year on January 1, 2023. Fiscal 2025 ended January 2, 2026, fiscal 2024 ended January 3, 2025 and fiscal 2023 ended December 29, 2023. Fiscal 2025 included 52 weeks, fiscal 2024 included 53 weeks and fiscal 2023 included 52 weeks.

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 and liabilities, the reported amounts of revenues and expenses for the periods covered and certain amounts disclosed in the notes to our consolidated financial statements. 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. Areas requiring estimates and assumptions by our management include the following:

We, and our equity method investments, recognize revenue in accordance with ASC 606. Revenue is measured based on the amount of consideration specified in a contract with a customer. Revenue is recognized when and as our performance obligations under the terms of the contract are satisfied, which occurs with the transfer of control of the goods or services to the customer. We recognize revenue on substantially all of our contracts over time, as performance obligations are satisfied, due to

the continuous transfer of control to the customer. We determine whether to recognize revenue on a gross or net basis by assessing if we control the goods or services provided by third parties before they reach the customer, acting as the principal when we do and as the agent when we only arrange for another party to provide them. Our contracts are generally accounted for as a single performance obligation and are not segmented between types of services provided. We recognize revenue on those contracts over time using the cost-to-cost method, based primarily on contract costs incurred to date compared to total estimated contract costs at completion. Contract costs include all direct materials, labor and subcontractors costs and indirect costs related to contract performance. We believe this method is the most accurate measure of contract performance because it directly measures the value of the goods and services transferred to the customer. For all other contracts we recognize revenue when services are performed which generally coincides with our ability to bill.

To determine the proper revenue recognition method for contracts, we evaluate whether two or more contracts should be combined and accounted for as one single contract and whether the combined or single contract should be accounted for as more than one performance obligation. This evaluation requires judgment and the decision to combine a group of contracts or separate a combined or single contract into multiple performance obligations could change the amount of revenue and profit recorded in a given period. Contracts are considered to have a single performance obligation if the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts primarily because we provide a significant service of integrating a complex set of tasks and components into a single project or capability. Contracts that cover multiple phases of the product lifecycle (development, construction and maintenance & support) are typically considered to have multiple performance obligations even when they are part of a single contract.

For a limited number of contracts with multiple performance obligations, we allocate the transaction price to each performance obligation using our best estimate of the relative standalone selling price of each distinct good or service in the contract. In cases where we do not provide the distinct good or service on a standalone basis, the primary method used to estimate standalone selling price is the expected cost plus a margin approach, under which we forecast our expected costs of satisfying a performance obligation and then add an appropriate margin for that distinct good or service.

Fixed-price contracts also include unit-rate contracts. 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. Unit-rate contracts are considered fixed-price contracts with the only variable being units of work to be performed. 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 rates for specified cost categories. The rates are designed to 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 type is generally used for defined and non-defined scope contracts where there is a higher degree of uncertainty and risks as to the scope 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 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 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 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, including the types of costs that are allowable, is based on specific negotiations with each customer.

Contract costs include all direct materials, labor and subcontractor costs and an allocation of indirect costs related to contract performance. Customer-furnished materials are included in both contract revenue and cost of revenue when management concludes that the company is acting as a principal rather than as an agent. Project mobilization costs incurred are capitalized as deferred assets and amortized on a straight-line basis over the anticipated term of the contract or a specified period of performance consistent with the transfer of control of the performance obligation to the client. These costs incurred may be to transition the services, employees and equipment to or from the customer, a prior contract or prior contractor. Pre-contract costs are expensed as incurred unless they are expected to be recovered from the client.

Contract costs incurred for U.S. government contracts, including indirect costs, are subject to audit and adjustment by the DCAA. 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.

We provide limited warranties to customers for work performed under our contracts that typically extend for a limited duration following substantial completion of our work on a project. Such warranties are not sold separately and do not provide customers with a service in addition to assurance of compliance with agreed-upon specifications. Accordingly, these types of warranties are not considered to be separate performance obligations.

In addition to the variable contract price under cost-reimbursable contracts, it is common for our contracts to contain variable consideration in the form of award fees, incentive fees, performance bonuses, liquidated damages or penalties that may increase or decrease the transaction price. These variable amounts generally are awarded upon achievement of certain performance metrics, program milestones or targets and can be based on customer discretion. Other contract provisions also give rise to variable consideration such as unapproved change orders and claims, and on certain contracts, index-based price adjustments. We estimate the amount of variable consideration at the most likely amount to which we expect to be entitled. Variable consideration is included in the transaction price when it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include such amounts in the transaction price are based largely on our assessment of legal enforceability, anticipated performance and any other information (historical, current or forecasted) that is reasonably available to us.

Variable consideration associated with claims and unapproved change orders is included in the transaction price only to the extent of costs incurred. We recognize claims against vendors, subcontractors and others as a reduction in recognized costs when enforceability is established by the contract and the amounts are reasonably estimable and probable of recovery. Reductions in costs are recognized to the extent of the lesser of the amounts management expects to recover or actual costs incurred.

Due to the nature of the work required to be performed on many of our performance obligations, the estimation of total revenue and cost at completion is complex and subject to many variables and requires significant judgment. As a significant change in estimated total revenue and cost could affect the profitability of our contracts, we routinely review and update our contract-related estimates through a disciplined project review process in which management reviews the progress and execution of our performance obligations and the EAC. As part of this process, management reviews information including, but not limited to, outstanding contract matters, progress towards completion, program schedule and the associated changes in estimates of revenues and costs. Management must make assumptions and estimates regarding the availability and productivity of labor, the complexity of the work to be performed, the availability and cost of materials, the performance of subcontractors

We recognize changes in contract estimates on a cumulative catch-up basis in the period in which the changes are identified. Such changes in contract estimates can result in the recognition of revenue in a current period for performance obligations which were satisfied or partially satisfied in prior period. Changes in contract estimates may also result in the reversal of previously recognized revenue if the current estimate differs from the previous estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, we recognize the total loss in the period it is identified. See Note 3. "Revenue" for changes in all other project-related estimates.

Contracts are often modified to account for changes in contract specifications and requirements. Most of our contract modifications are for goods or services that are not distinct from existing contracts due to the significant integration provided in the context of the contract and are accounted for as if they were part of the original contract. The effect of a contract modification on the transaction price and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. We account for contract modifications prospectively when the modification results in the promise to deliver additional goods or services that are distinct and the increase in price of the contract is for the same amount as the stand-alone selling price of the additional goods or services included in the modification.

Billing practices are governed by the contract terms of each project based upon costs incurred, achievement of milestones or predetermined schedules. Billings do not necessarily correlate with revenue recognized over time using the percentage-of-completion method. Contract assets include unbilled amounts typically resulting from revenue under long-term contracts when the percentage-of-completion method of revenue recognition is used, and revenue recognized exceeds the amount billed to the customer. Contract liabilities consist of advance payments and billings in excess of revenue recognized as well as deferred revenue.

Retainage, included in contract assets, represent the amounts withheld from billings by our clients pursuant to provisions in the contracts and may not be paid to us until the completion of specific tasks or the completion of the project and, in some instances, for even longer periods. Retainage may also be subject to restrictive conditions such as performance guarantees.

The payment terms of our contracts from time to time require the customer to make advance payments as well as interim payments as work progresses. Advance payments generally are not considered to contain a significant financing component as we expect to recognize those amounts in revenue within a year of receipt as work progresses on the related performance obligation.

Selling, general and administrative expenses include charges for such items as executive management, corporate business development, information technology, finance and accounting, human resources and various other functions. The Company classifies indirect costs incurred within or allocated to its U.S. government customers as overhead (included in cost of revenues) or selling, general and administrative expenses in the same manner as such costs are defined in the Company’s disclosure statements under CAS.

Accounts receivable include amounts billed and currently due from customers, amounts billable where the right to consideration is unconditional and amounts unbilled. Amounts billed and unbilled are recognized at estimated realizable value and consist of costs and fees, substantially all of which are expected to be billed and collected within one year. Unbilled amounts also include rate variances that are billable upon negotiation of final indirect rates with the DCAA.

We establish an allowance for credit losses based on the assessment of our clients' ability to pay. In addition to such allowances, there are often items in dispute or being negotiated that may require us to make an estimate as to the ultimate outcome. Past due receivable balances are written off when our internal collection efforts have been unsuccessful in collecting the amounts due.

Additionally, we sell certain receivables to unrelated third-party financial institutions under various accounts receivable monetization programs. The receivables sold under the agreements do not allow for recourse for any credit risk related to our customers if such receivables are not collected by the third-party financial institutions. The Company accounts for these receivable transfers as a sale under ASC Topic 860, Transfers and Servicing as the receivables have been legally isolated from the Company, the financial institution has the right to pledge or exchange the assets received and we do not maintain effective control over the transferred accounts receivable. Our only continuing involvement with the transferred financial assets is as the collection and servicing agent. As a result, the accounts receivable balance on the consolidated balance sheets is presented net of the transferred amount. See Note 20. "Fair Value of Financial Instruments and Risk Management" to our consolidated financial statements for further information on sales of receivables.

Property, plant and equipment are reported at cost less accumulated depreciation except for those assets that have been written down to their fair values due to impairment. Expenditures for major additions and improvements are capitalized and minor replacements, maintenance and repairs are charged to expense as incurred. The cost of property, plant and equipment sold or otherwise disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in operating income for the respective period. Depreciation is generally provided on the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized using the straight-line method over the shorter of the useful life of the improvement or the lease term. See Note 7. “Property, Plant and Equipment” to our consolidated financial statements for our discussion on property, plant and equipment.

We account for business combinations using the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations ("ASC 805"). Under this method, the purchase consideration is measured at fair value, and the identifiable tangible and intangible assets acquired and liabilities assumed are recognized at their estimated acquisition‑date fair values, with any excess recognized as goodwill. We engage third-party appraisal firms when appropriate to assist in the fair value determination of intangible assets. Initial purchase price allocations are subject to revisions within the measurement period, not to exceed one year from the date of acquisition. Acquisition-related expenses and transaction costs associated with business combinations are expensed as incurred.

Goodwill is an asset representing the excess cost over the fair market value of net assets and identifiable intangibles acquired in business combinations. In accordance with ASC Topic 350, Intangibles - Goodwill and Other, goodwill is not amortized but is tested annually for impairment or on an interim basis when indicators of potential impairment exist. Goodwill is tested for impairment at the reporting unit level. Our reporting units are our operating segments or components of operating segments where discrete financial information is available and segment management regularly reviews the operating results. For purposes of impairment testing, goodwill is allocated to the applicable reporting units based on our reporting structure.

Goodwill is assessed annually for possible impairment as of the first day of our fourth quarter each fiscal year, and on an interim basis when indicators of possible impairment exist. We have the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. Qualitative factors assessed for each of the applicable reporting units include, but are not limited to, changes in macroeconomic conditions, industry and market considerations, cost factors, discount rates, competitive environments and financial performance of the reporting units. If the qualitative assessment indicates that it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value, a quantitative test is required.

We also have the option to proceed directly to the quantitative test. Under the quantitative impairment test, the estimated fair value of each reporting unit is compared to its carrying value, including goodwill. If the carrying value of the reporting unit including goodwill exceeds its fair value, an impairment charge equal to the excess would be recognized, up to a maximum amount of goodwill allocated to that reporting unit. We can resume the qualitative assessment in any subsequent period for any reporting unit.

During fiscal 2025, 2024 and 2023, management performed a qualitative impairment assessment of our reporting units, of which there were no indications that it was more likely than not that the fair value of our reporting units were less than their respective carrying values. As such, a quantitative goodwill test was not required, and no goodwill impairment was recognized in fiscal 2025, 2024 and 2023. See Note 8. “Goodwill and Intangible Assets” to our consolidated financial statements for reported goodwill in each of our segments.

We had intangible assets with net carrying values of $727 million and $763 million as of January 2, 2026 and January 3, 2025, respectively. Intangible assets with indefinite lives are not amortized but are subject to annual impairment tests or on an interim basis when indicators of potential impairment exist. An intangible asset with an indefinite life is impaired if its carrying value exceeds its fair value. During fiscal 2025, 2024 and 2023, there were no triggering events identified. Intangible assets with finite lives are amortized on a straight-line basis over the useful life of those assets, ranging from 1 year to 25 years. See Note 8. “Goodwill and Intangible Assets” to our consolidated financial statements for further discussion of our intangible assets.

We account for non-marketable investments using the equity method of accounting if the investment gives us the ability to exercise significant influence over, but not control, of an investee. Significant influence generally exists if we have an ownership interest representing between 20% and 50% of the voting stock of the investee. Under the equity method of accounting, investments are stated at initial cost and are adjusted for subsequent additional investments and our proportionate share of earnings or losses and distributions.

Equity in earnings (losses) of unconsolidated affiliates, in the consolidated statements of operations, reflects our proportionate share of the investee's net income, including any associated taxes. Our proportionate share of the investee’s other comprehensive income (loss), net of income taxes, is recorded in the consolidated statements of shareholders’ equity and consolidated statements of comprehensive income (loss). In general, the equity investment in our unconsolidated affiliates is equal to our current equity investment plus those entities' undistributed earnings.

We evaluate our equity method investments for impairment at least annually or whenever events or changes in circumstances indicate, in management’s judgment, that the carrying value of an investment may have experienced an other-than-temporary decline in value. When evidence of loss in value has occurred, management compares the estimated fair value of the investment to the carrying value of the investment to determine whether an impairment has occurred. If the estimated fair value is less than the carrying value and management considers the decline in value to be other than temporary, the excess of the carrying value over the estimated fair value is recognized in the financial statements as an impairment. See Note 9. "Equity Method Investments and Variable Interest Entities" to our consolidated financial statements for our discussion on equity method investments.

We evaluate distributions received from our equity method investments using the nature of distribution approach. Under this approach, we evaluate the nature of activities of the investee that generated the distribution. The distributions received are either classified as a return on investment, which is presented as a component of operating activities on our consolidated statements of cash flows, or as a return of investment, which is presented as a component of investing activities on our consolidated statements of cash flows. For BRIS only, we apply the cumulative earnings approach for the cash flow classification of distributions as information is not available to evaluate the nature of the activities of the joint venture.

Other investments are investments in equity securities of privately held companies without readily determinable fair values and are included in other assets on our consolidated balance sheets. These investments are accounted for under the measurement alternative, provided that KBR does not have the ability to exercise significant influence or control over the investees. We measure the investments at cost, less any impairment, and adjust the carrying value to fair value resulting from observable transactions for identical or similar investments of the investee. If it is determined that impairment indicators exist and the carrying value is less than the fair value, we adjust the carrying value of the investment to its fair value and record the related impairment. The gains and losses on the investments are recognized in other non-operating expense on our consolidated statements of operations.

The majority of our joint ventures are VIEs. We account for VIEs in accordance with ASC Topic 810, Consolidation ("ASC 810"), which requires the consolidation of VIEs in which a company has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses or the right to receive the benefits from the VIE that could potentially be significant to the VIE. If a reporting enterprise meets these conditions, then it has a controlling financial interest and is the primary beneficiary of the VIE. Our unconsolidated VIEs are accounted for under the equity method of accounting.

We assess all newly created entities and those with which we become involved to determine whether such entities are VIEs and, if so, whether or not we are their primary beneficiary. Most of the entities we assess are incorporated or unincorporated joint ventures formed by us and our partner(s) for the purpose of executing a project or program for a customer and are generally dissolved upon completion of the project or program. Many of our long-term, commercial projects are executed through such joint ventures. Although the joint ventures in which we participate own and hold contracts with the customers, the services required by the contracts are typically performed by the joint venture partners, or by other subcontractors under subcontracts with the joint ventures. Typically, these joint ventures are funded by advances from the project owner, and accordingly, require little or no equity investment by the joint venture partners but may require subordinated financial support from the joint venture partners such as letters of credit, performance and financial guarantees or obligations to fund losses incurred by the joint venture. Other joint ventures, such as PFIs, generally require the partners to invest equity and take an ownership position in an entity that manages and operates an asset after construction is complete. The assets of joint ventures are restricted for use to the obligations of the particular joint venture and are not available for our general operations.

We perform a qualitative assessment to determine whether we are the primary beneficiary once an entity is identified as a VIE. Thereafter, we continue to re-evaluate whether we are the primary beneficiary of the VIE in accordance with ASC 810. A qualitative assessment begins with an understanding of the nature of the risks in the entity as well as the nature of the entity’s activities. These include the terms of the contracts entered into by the entity, ownership interests issued by the entity and how they were marketed and the parties involved in the design of the entity. We then identify all of the variable interests held by parties involved with the VIE including, among other things, equity investments, subordinated debt financing, letters of credit, financial and performance guarantees and contracted service providers. Once we identify the variable interests, we determine those activities which are most significant to the economic performance of the entity and which variable interest holder has the power to direct those activities. Though infrequent, some of our assessments reveal no primary beneficiary because the power to direct the most significant activities that impact the economic performance is held equally by two or more variable interest holders who are required to provide their consent prior to the execution of their decisions. Most of the VIEs with which we are involved have relatively few variable interests and are primarily related to our equity investment, significant service contracts and other subordinated financial support. See Note 9. "Equity Method Investments and Variable Interest Entities" to our consolidated financial statements for our discussion on variable interest entities.

Our pension benefit obligations and expenses are calculated using actuarial models and methods. The more critical assumption and estimate used in the actuarial calculations is the discount rate for determining the current value of benefit obligations. Other assumptions and estimates used in determining benefit obligations and plan expenses include expected rate of return on plan assets, inflation rates and demographic factors such as retirement age, mortality and turnover. These assumptions and estimates are evaluated periodically (typically annually) and are updated accordingly to reflect our actual experience and expectations.

The discount rate used to determine the benefit obligations was computed using a yield curve approach that matches plan specific cash flows to a spot rate yield curve based on high quality corporate bonds. The expected long-term rate of return on assets was determined by a stochastic projection that takes into account asset allocation strategies, historical long-term performance of individual asset classes, an analysis of additional return (net of fees) generated by active management, risks using standard deviations and correlations of returns among the asset classes that comprise the plans' asset mix. Plan assets are comprised primarily of equity funds and securities, fixed income funds and securities, real estate and other funds. As we have

Unrecognized actuarial gains and losses are recognized using the corridor method over a period of approximately 20 years, which represents a reasonable systematic method for amortizing gains and losses for the employee group. Our unrecognized actuarial gains and losses arise from several factors, including experience and assumption changes in the obligations and the difference between expected returns and actual returns on plan assets. The difference between actual and expected returns is deferred as an unrecognized actuarial gain or loss on our consolidated statement of comprehensive income (loss) and is recognized as a decrease or an increase in future pension expense.

We recognize the amount of taxes payable or refundable for the year and deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the financial statements or tax returns. We provide a valuation allowance for deferred tax assets if it is more likely than not that these items will not be realized. See Note 12. “Income Taxes” to our consolidated financial statements for our discussion on income taxes.

Income taxes are accounted for under the asset and liability method. We provide a valuation allowance for deferred tax assets if it is more likely than not that these items will not be realized. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. A current tax asset or liability is recognized for the estimated taxes refundable or payable on tax returns. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. A valuation allowance is provided for deferred tax assets if it is more likely than not that these items will not be realized. We consider the scheduled reversal of deferred tax liabilities, income available from carryback years, projected future taxable income and available tax planning strategies in making this assessment. Additionally, we use forecasts of certain tax elements such as taxable income and foreign tax credit utilization in making this assessment of realization. Given the inherent uncertainty involved with the use of such estimates and assumptions, there can be significant variation between estimated and actual results.

We have operations in numerous countries other than the United States. Consequently, we are subject to the jurisdiction of a significant number of taxing authorities. The income earned in these various jurisdictions is taxed on differing bases, including income actually earned, income deemed earned and revenue-based tax withholding. The final determination of our tax liabilities involves the interpretation of local tax laws, tax treaties and related authorities in each jurisdiction. Changes in the operating environment, including changes in tax law and currency/repatriation controls, could impact the determination of our tax liabilities for a tax year.

We recognize the effect of income tax positions only if it is more likely than not that those positions will be sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company records potential interest and penalties related to unrecognized tax benefits in income tax expense.

Tax filings of our subsidiaries, unconsolidated affiliates and related entities are routinely examined by tax authorities in the normal course of business. These examinations may result in assessments of additional taxes, which we work to resolve with the tax authorities and through the judicial process. Predicting the outcome of disputed assessments involves some uncertainty. Factors such as the availability of settlement procedures, willingness of tax authorities to negotiate and the operation and impartiality of judicial systems vary across the different tax jurisdictions and may significantly influence the ultimate outcome. We review the facts for each assessment, and then utilize assumptions and estimates to determine the most likely outcome and provide taxes, interest and penalties as needed based on this outcome.

We recognize all derivatives at fair value on the balance sheet. Derivatives that are not designated as hedges in accordance with ASC 815, are adjusted to fair value and such changes are reflected in the results of operations. If the derivative is designated as a cash flow hedge, all changes in the fair value of derivatives are recognized in other comprehensive income (loss) and are subsequently reclassified into earnings in the period in which the hedged forecasted transaction affects earnings. See Note 20. "Fair Value of Financial Instruments and Risk Management" to our consolidated financial statements for our discussion on derivative instruments.

Recognized gains or losses on derivatives entered into to manage project related foreign exchange risk are included in gross profit. Foreign currency gains and losses for hedges of non-project related foreign exchange risk are reported within other non-operating income (expense) on our consolidated statements of operations. Realized gains or losses on derivatives used to manage interest rate risk are included in interest expense in our consolidated statements of operations.

Financial instruments which potentially subject our company to concentrations of credit risk consist principally of cash and cash equivalents and trade receivables. Our cash is primarily held with major banks and financial institutions throughout the world. We believe the risk of any potential loss on deposits held in these institutions is minimal.

We have revenues and receivables from transactions with an external customer that amounts to 10% or more of our revenues which are generally not collateralized. We generated significant revenues from transactions with the U.S. government and U.K. government within our MTS business segment. No other customers represented 10% or more of consolidated revenues in any of the periods presented.

Our reporting currency is the U.S. dollar. The functional currency of our non-U.S. subsidiaries is typically the currency of the primary environment in which they operate. Where the functional currency for a non-U.S. subsidiary is not the U.S. dollar, translation of all of the assets and liabilities (including long-term assets, such as goodwill) to U.S. dollars is based on exchange rates in effect at the balance sheet date. Translation of revenues and expenses to U.S. dollars is based on the average rate during the period and shareholders’ equity accounts are translated at historical rates. Translation gains or losses, net of income tax effects, are reported in accumulated other comprehensive loss on our consolidated balance sheets.

Transaction gains and losses that arise from foreign currency exchange rate fluctuations on transactions denominated in a currency other than the functional currency are recognized in income each reporting period when these transactions are either settled or remeasured. Transaction gains and losses on intra-entity foreign currency transactions and balances including advances and demand notes payable, on which settlement is not planned or anticipated in the foreseeable future, are recorded in accumulated other comprehensive loss on our consolidated balance sheets.

We account for share-based payments, including grants of employee stock options, restricted stock-based awards and performance cash units, in accordance with ASC Topic 718, Compensation-Stock Compensation ("ASC 718"), which requires that all share-based payments (to the extent that they are compensatory) be recognized as an expense in our consolidated statements of operations based on their fair values on the award date and the estimated number of shares of common stock we ultimately expect to vest. We recognize share-based compensation expense on a straight-line basis over the service period of the award, which is no greater than 3 years. If an award is modified after the grant date, incremental compensation cost is recognized immediately as of the modification. The benefits of tax deductions in excess of the compensation cost recognized for the options (excess tax benefits) are classified as additional paid-in-capital and cash retained as a result of these excess tax benefits is presented in the statements of cash flows as financing cash inflows. See Note 18. “Share-based Compensation and Incentive Plans” to our consolidated financial statements for our discussion on share-based compensation and incentive plans.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The ASU requires that an entity disclose specific categories in the effective tax rate reconciliation as well as provide additional information for reconciling items that meet a quantitative threshold. Further, the ASU requires certain disclosures of state versus federal income tax expense and taxes paid. We adopted this standard effective for our 2025 fiscal year on a prospective basis. Refer to Note 12. "Income Taxes" for additional information.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. ASU 2024-03 requires disclosure of additional information about certain income statement expense categories. ASU 2024-03 will be effective for our 2027 fiscal year ending December 31, 2027. Early adoption is permitted and the amendments can be applied on a prospective or retrospective basis. We expect this ASU to only impact our disclosures with no impacts to our results of operations, cash flows and financial condition.

In September 2025, the FASB issued ASU 2025-06, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. This guidance removes all references to project stages throughout ASC 350-40 and clarifies the threshold entities apply to begin capitalizing costs. Under the new standard, cost capitalization should only commence when an entity has committed to funding a software project and it is probable the project will be completed and the software will be used for its intended function. The amendments are effective for annual reporting periods beginning after December 15, 2027 and interim reporting periods within those annual reporting periods. Entities may apply the guidance using a prospective, retrospective or modified transition approach. Early adoption is permitted as of the beginning of an annual reporting period. We are currently determining the preferred transition approach and assessing the impact of the ASU on our disclosures and financial statements, including the timing of its adoption.
