Leonardo DRS, Inc.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Summary of Significant Accounting Policies

A. Organization

Leonardo DRS, Inc., together with its wholly owned subsidiaries (hereinafter, “DRS,” “the Company,” “us,” “our,” or “we”) is a supplier of defense electronics products, systems and military support services. The Company’s largest stockholder is Leonardo S.p.A., an Italian multi-national aerospace, defense and security company headquartered in Rome, Italy, through its ultimate sole ownership of Leonardo US Holding, LLC (“US Holding”). US Holding is the majority stockholder of the Company.

DRS is a provider of defense products and technologies that are used across land, air, sea, space and cyber domains. Our diverse array of defense systems and solutions are offered to all branches of the U.S. military, major aerospace and defense prime contractors, government intelligence agencies, international military customers and industrial markets for deployment on a wide range of military platforms. We focus our capabilities in areas of critical importance to the U.S. military, such as advanced sensing, network computing, force protection and electric power and propulsion.

These capabilities directly align with ourtwo reportable operating segments: Advanced Sensing and Computing (“ASC”) and Integrated Mission Systems (“IMS”). The U.S. government is our largest customer and accounts for approximately 82% and 81% of our total revenues as an end-user for the nine months ended September 30, 2026 and 2025, respectively. Our U.S. government revenues are highly concentrated with the U.S. Department of War, also known as the U.S. Department of Defense (the “DoW”). Specific international and commercial market opportunities exist within these segments and comprise approximately 18% and 19% of our total revenues for the nine months ended September 30, 2026 and 2025, respectively. Ourtwo reportable segments reflect the way performance is assessed and resources are allocated by our Chief Executive Officer, who is our chief operating decision maker (“CODM”).

B. Basis of Presentation

The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of DRS, its wholly owned subsidiaries and its controlling interests and contain all adjustments, which are of a normal and recurring nature, considered necessary by management to present fairly the financial position, results of operations and cash flows for the periods presented. Interests in ventures that are controlled by the Company, or for which the Company is otherwise deemed to be the primary beneficiary, are consolidated. For joint ventures in which the Company does not have a controlling interest, but exerts significant influence, the Company applies the equity method of accounting. All intercompany transactions and balances have been eliminated in consolidation.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions include those relating to the recognition of contract revenues and estimated costs to complete contracts in process, recoverability of reported amounts of goodwill and intangible assets, valuation of acquired intangibles, accounting for business combinations, valuation of pensions and other postretirement benefits, the valuation of deferred tax assets and liabilities and the valuation of unrecognized tax benefits. Actual results could differ from these estimates.

The unaudited Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These rules and regulations permit some of the information and footnote disclosures included in financial statements prepared in accordance with U.S. GAAP to be condensed or omitted.

These unaudited Consolidated Financial Statements should be read in conjunction with our audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2025.

C. New Accounting Pronouncements

Disaggregation of Income Statement Expenses

In November 2024, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires disclosure of specified information about certain costs and expenses. The new standard is effective for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, and may be applied on a prospective or retrospective basis. We are currently evaluating the impact of adopting this new pronouncement.

Targeted Improvements to the Accounting for Internal-Use Software

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, which removes references to project stages, requiring companies to capitalize internal-use software costs when management commits to funding the software project and it is probable the project will be completed. The new standard is effective for fiscal years beginning after December 15, 2027 and interim periods within those fiscal years, and may be applied on a prospective, modified transition, or retrospective transition basis. We are currently evaluating the impact of adopting this new pronouncement.

Accounting for Government Grants Received by Business Entities

In December 2025, the FASB issued ASU 2025-10, Government Grants (Topic 832)—Accounting for Government Grants Received by Business Entities, which establishes the accounting for government grants received by business entities. The new standard is effective for fiscal years beginning after December 15, 2028 and interim periods within those fiscal years, and may be applied on a modified prospective, modified retrospective, or retrospective transition basis. We are currently evaluating the impact of adopting this new pronouncement.

Note 2. Revenue from Contracts with Customers

Contract Estimates

Revenues for the majority of our contracts are measured using the over time, percentage of completion cost-to-cost method of accounting to calculate percentage of completion. We believe this is an appropriate measure of progress toward satisfaction of performance obligations as this measure most accurately depicts the progress of our work and transfer of control to our customers. Due to the long-term nature of many of our contracts, developing the estimated transaction price and total cost at completion often requires judgment. The estimated transaction price may include variable consideration such as performance incentives, requests for equitable adjustment (“REAs”) and claims. Variable consideration is included in the estimated transaction price only to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Factors that must be considered in estimating the cost of the work to be completed include the nature and complexity of the work to be performed, subcontractor performance and the risk and impact of delayed performance.

After establishing the estimated total cost at completion, we follow a standard Estimate at Completion (“EAC”) process in which we review the progress and performance on our ongoing contracts on a routine basis. Adjustments to original estimates for a contract's revenue, estimated costs at completion and estimated profit or loss often are required as work progresses under a contract, as experience is gained and as more information is obtained, even though the scope of work required under the contract may not change and are also required if contract modifications occur. When adjustments in estimated total costs at completion are determined, the related impact on revenue and operating earnings are recognized using the cumulative catch-up method, which recognizes in the current period the cumulative effect of such adjustments for all prior periods. Any anticipated losses on these contracts are fully recognized in the period in which the losses become evident.

Net EAC adjustments had the following impacts for the periods presented:

The impacts noted above are attributed primarily to changes in our fixed-price programs. As changes happen in the design required to achieve contractual specifications, those changes often result in a change in the programs’ estimates and related profitability.

Contract Assets and Liabilities

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on the Consolidated Balance Sheets. Amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., biweekly or monthly) or upon achievement of contractual milestones. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. However, we sometimes receive advances or deposits from our customers before revenue is recognized, resulting in contract liabilities. Contract assets and contract liabilities as of the dates presented were:

Revenue recognized in the nine months ended September 30, 2026 and 2025, that was included in the contract liability balance at the beginning of each period was $411 million and $270 million, respectively.

Value of Remaining Performance Obligations

As of September 30, 2026, the total value of our remaining performance obligations was $9,381 million. We expect to recognize approximately 40% of our September 30, 2026 remaining performance obligations as revenue over the next twelve months, with the remainder to be recognized thereafter. Approximately 40% of our remaining performance obligations relates to long-term contracts on electric power and propulsion programs with the U.S. Navy, which are expected to be recognized as revenue over a span of up to 11 years.

Disaggregation of Revenue

ASC: ASC revenue is primarily derived from U.S. government development and production contracts and is generally recognized using the over time, percentage of completion cost-to-cost method of accounting. We disaggregate ASC revenue by geographical region, customer relationship and contract type. We believe these categories best depict how the nature, amount, timing and uncertainty of ASC revenue and cash flows are affected by economic factors.

(1)Includes revenue derived from cost-plus and time-and-materials contracts.

IMS: IMS revenue is primarily derived from U.S. government development and production contracts and is generally recognized using the over time, percentage of completion cost-to-cost method of accounting. We disaggregate IMS revenue by geographical region, customer relationship and contract type. We believe these categories best depict how the nature, amount, timing and uncertainty of IMS revenue and cash flows are affected by economic factors.

(1)Includes revenue derived from cost-plus and time-and-materials contracts.

Note 3. Accounts Receivable

Accounts receivable consists of the following:

As of September 30, 2026 and December 31, 2025, the Company has $57 million and $53 million of noncurrent accounts receivable, respectively, that are included in other noncurrent assets in our Consolidated Balance Sheets.

The Company maintains certain agreements with financial institutions to sell certain trade receivables. See Note 4: Sale of Receivablesfor more information.

Note 4. Sale of Receivables

The Company is party to factoring facilities with various financial institutions (the “purchasers”) with an aggregate capacity of $175 million and $225 million as of September 30, 2026 and December 31, 2025, respectively.

During the nine months ended September 30, 2026 and 2025, the Company incurred immaterial purchase discount fees, which are presented in general and administrative expenses on the Consolidated Statements of Earnings.

The table below summarizes the activity under the factoring facilities:

(1)Represents cash collected on behalf of purchasers and not yet remitted. This balance is included within short-term borrowings and current portion of long-term debt in the Consolidated Balance Sheets.

Note 5. Inventories

Inventories consist of the following:

Note 6. Property, Plant and Equipment

Property, plant and equipment by major asset class consists of the following:

Depreciation expense related to property, plant and equipment was $22 million and $61 million for the three and nine months ended September 30, 2026, respectively, and $18 million and $53 million for the three and nine months ended September 30, 2025, respectively.

Note 7. Other Liabilities

The following table summarizes significant other liabilities by balance sheet caption:

Note 8. Intangible Assets

Intangible assets consist of the following:

Amortization expense related to acquired intangible assets was $5 million for the three months ended September 30, 2026 and 2025, and $16 million for the nine months ended September 30, 2026 and 2025.

Note 9. Income Taxes

Our effective tax rate was 0.9% and 10.2% for the three and nine months ended September 30, 2026, respectively, and 17.2% and 17.0% for the three and nine months ended September 30, 2025, respectively. For the three and nine months ended September 30, 2026, the effective tax rate was lower than the statutory rate primarily due to the recognition of discrete tax benefits associated with the reduction in unrecognized tax benefits, excess tax benefits from the vesting of stock-based awards and the purchase of tax credits at a discount to face value. For the nine months ended September 30, 2025, the effective tax rate was lower than the statutory rate primarily due to excess tax benefits from the vesting of stock-based awards. During the three and nine months ended September 30, 2026, the Company recognized an income tax benefit of approximately $22 million from the release of unrecognized tax benefits in connection with a short period return for 2022 following the expiration of the applicable statute of limitations. During the three and nine months ended September 30, 2026, the Company purchased approximately $20 million in tax credits for approximately $18 million in cash. The purchased tax credits will be utilized to partially offset the Company’s Federal and New Jersey tax liabilities for 2025.

Note 10. Debt

The Company’s debt consists of the following:

Term Loan

In November 2022, the Company entered into a senior unsecured credit agreement with Bank of America, N.A. in the amount of $500 million (the “2022 Credit Agreement”) with a maturity of November 29, 2027. The 2022 Credit Agreement provided for a term loan (the “2022 Term Loan A”) of $225 million. The fair value of the 2022 Term Loan A was approximately $190 million at December 31, 2025. The fair value of the Company’s outstanding debt obligations is calculated using Level 2 inputs, based on interest rates available for debt with terms and maturities similar to the Company’s existing debt arrangements.

In January 2026, the Company repaid the remaining outstanding balance of the 2022 Term Loan A in the amount of $191 million and terminated the 2022 Credit Agreement. There was no prepayment penalty or other fee associated with prepaying the principal balance.

Credit Facilities

The 2022 Credit Agreement provided for a revolving credit facility available for the working capital needs of the Company (the “2022 Revolving Credit Facility”). As of December 31, 2025, the 2022 Revolving Credit Facility had a limit of $275 million. There wasno outstanding balance on the 2022 Revolving Credit Facility as of December 31, 2025. As noted above, the 2022 Credit Agreement was terminated in January 2026.

In January 2026, the Company entered into a senior unsecured credit agreement with JPMorgan Chase Bank N.A. and the other lenders party thereto (the “2026 Credit Agreement”). The 2026 Credit Agreement provides for a revolving credit facility available for the working capital requirements of the Company (the “2026 Revolving Credit Facility”). The 2026 Revolving Credit Facility has a limit of $500 million and expires in January 2031. There wasno outstanding balance on the 2026 Revolving Credit Facility as of September 30, 2026. Loans under the 2026 Revolving Credit Facility bear interest at a variable rate generally based on the Secured Overnight Financing Rate (“SOFR”), plus a spread ranging from 1.25% to 1.63% depending on the leverage ratio, as defined in the 2026 Credit Agreement, or an alternative variable rate based on the higher of the prime rate, as defined in the 2026 Credit Agreement, the federal funds rate, or a rate generally based on the SOFR, in each case subject to an additional basis point spread as defined in the 2026 Credit Agreement. The Company also pays a commitment fee ranging between 0.15% and 0.30% depending on the Company’s leverage ratio applied to the unused balance of the 2026 Revolving Credit Facility. The 2026 Credit Agreement allows for up to $75 million of the 2026 Revolving Credit Facility to be used to issue letters of credit in support of Company contracts. As of September 30, 2026, the Company had outstanding letters of credit against the 2026 Revolving Credit Facility of $9 million.

In addition to the letters of credit issued under the 2026 Revolving Credit Facility, the Company maintains uncommitted working capital credit facilities with certain financial institutions in the aggregate of $105 million at September 30, 2026 and December 31, 2025 (the “Financial Institution Credit Facilities”). The sole purpose of the Financial Institution Credit Facilities is to support standby letter of credit issuances on contracts with customers. The Company had letters of credit outstanding of approximately $48 million and $54 million as of September 30, 2026 and December 31, 2025, respectively, which reduce the available capacity of the Financial Institution Credit Facilities by an equal amount.

Maturities

Maturities of debt as of September 30, 2026 are as follows:

Note 11. Earnings Per Share (“EPS”), Stock Repurchases and Dividends

EPS

Basic EPS is computed by dividing net earnings by the weighted average number of shares of common stock outstanding during each period. The computation of diluted EPS includes the dilutive effect of outstanding stock-based compensation awards (which primarily consist of employee stock options, restricted stock units, and performance-based restricted stock units).

Stock Repurchases

On February 20, 2025, the Company announced that its Board of Directors (the “Board”) approved a stock repurchase program that allows the Company to purchase up to $75 million of its outstanding common stock through March 4, 2027, subject to market conditions. As of September 30, 2026, the Company has repurchased approximately $62 million under the program. The Company retires its common stock upon repurchase with the excess over par value allocated to additional paid-in capital.

Dividends

The Company declared and paid a quarterly dividend of $0.09 per share of its common stock during the three months ended September 30, 2026. Subsequent to quarter end, the Company’s Board declared a cash dividend of $0.09 per share of common stock payable on November 25, 2026 to stockholders of record as of the close of business on November 12, 2026.

Note 12. Commitments and Contingencies

Commitments

The Company’s commitments are primarily related to our lease agreements, purchase obligations, and credit agreements.

Contingencies

From time to time, we are subject to certain legal proceedings and claims in the ordinary course of business. These matters are subject to many uncertainties, and it is possible that some of these matters ultimately could be decided, resolved or settled in a manner adverse to us. Although the precise amount of liability that may result from these matters is not ascertainable, the Company believes that any amounts exceeding the Company's recorded accruals should not materially adversely affect the Company's financial condition or liquidity. It is possible, however, that the ultimate resolution of those matters could result in a material adverse effect on the Company's results of operations and/or cash flows from operating activities for a particular reporting period. We establish reserves for specific legal matters when we determine that the likelihood of an unfavorable outcome is probable and the loss is reasonably estimable. The Company reviews the developments in contingencies that could affect the amount of the reserves that have been previously recorded. The Company adjusts provisions and changes to disclosures accordingly to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and updated information. Significant judgment is required to determine both the probability and the estimated amount of any potential losses.

As a government contractor, with customers including the U.S. government as well as various state and local government entities, the Company may be subject to audits, investigations and claims with respect to its contract performance, pricing, costs, cost allocations and procurement practices. Additionally, amounts billed under such contracts, including direct and indirect costs, are subject to potential adjustments before final settlement.

Management believes that adequate provisions for such potential audits, investigations, claims and contract adjustments, if any, have been made in the financial statements.

Note 13. Related Party Transactions

The Company has related party sales and purchases with Leonardo S.p.A., our indirect majority stockholder, and its other affiliates that occur in the regular course of business. Related party sales are included in revenues and were $5 million and $11 million for the three and nine months ended September 30, 2026, respectively, and $4 million and $11 million for the three and nine months ended September 30, 2025, respectively. Related party purchases are included in cost of revenues and were immaterial for the three and nine months ended September 30, 2026 and 2025. The receivables with the indirect majority stockholder and its other affiliates of $9 million and $5 million, respectively, and payables of $4 million and $5 million, respectively, as of September 30, 2026 and December 31, 2025, are included in accounts receivable, net and accounts payable in our Consolidated Balance Sheets. In addition, there were related party balances in contract assets of $6 million and $16 million at September 30, 2026 and December 31, 2025, respectively.

The Company had $10 million and $6 million of related party balances in contract assets with this company at September 30, 2026 and December 31, 2025, respectively.

Note 14. Segment Information

Operating segments represent components of an enterprise for which separate financial information is available that is regularly reviewed by the CODM in determining how to allocate resources and assess performance. The Company’s operating and reportable segments consist of ASC and IMS. All other operations, which consist primarily of DRS corporate headquarters and certain non-operating subsidiaries of the Company, are grouped in Corporate & Eliminations.

The CODM primarily uses operating earnings to manage the Company and allocate resources. Operating earnings is used to facilitate a comparison of the ordinary, ongoing and customary course of our operations on a consistent basis from period to period and provide an additional understanding of factors and trends affecting our business segments.

Certain information related to our segments for the periods ended September 30, 2026 and 2025 is presented in the following tables. Consistent accounting policies have been applied by all segments within the Company, within all reporting periods. Intersegment sales are generally transferred at cost to the buying segment, and the sourcing segment does not recognize a profit. Such intercompany operating earnings is eliminated in consolidation, so that the Company’s total revenues and operating earnings reflect only those transactions with external customers.

Revenues, expenses, and operating earnings by segment and the reconciliation to earnings before taxes for the periods ended September 30, 2026 and 2025 consist of the following:

(1)Includes ASC restructuring costs for the periods presented.

On July 28, 2026, the Company announced that it entered into a definitive agreement to acquire Raft LLC, an open-architecture mission software company focused on multi-domain data fusion and artificial intelligence for U.S. government and defense customers, for $450 million. We expect to fund the acquisition with cash on hand and borrowings under our 2026 Revolving Credit Facility. The transaction is subject to customary closing conditions and regulatory approvals, and is expected to close in the fourth quarter of 2026.
