SIGNIFICANT ACCOUNTING POLICIES

9 Months Ended

Basis of Presentation and Principles of Consolidation

The accompanying unaudited consolidated financial statements include the accounts of Telos and its subsidiaries (see Note 1 – Organization), all of whose issued and outstanding share capital is wholly owned directly and indirectly by Telos Corporation. All intercompany transactions and balances have been eliminated in consolidation.

The unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"), and the rules and regulations of the U.S. Securities and Exchange Commission ("SEC").

Basis of Presentation for Interim Periods

Certain information and footnote disclosures normally included for the annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted for the interim periods presented. We believe that the unaudited interim financial statements include all adjustments (which are normal and recurring) necessary to state fairly our financial position and the results of operations and cash flows for the periods presented.

The results of operations for the interim periods presented are not necessarily indicative of results that may be expected for the full year or future periods. The financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto for the year ended December 31, 2025, included in our Annual Report on Form 10-K for the fiscal year then ended. We continue to follow the accounting policies set forth in those financial statements.

Reclassification

Certain prior-period amounts have been reclassified to conform to the current period presentation. This reclassification relates to presenting "Inventories, net" as a separate line item on the unaudited consolidated balance sheets from "Other current assets."

Use of Estimates

The preparation of these unaudited consolidated financial statements, in conformity with U.S. GAAP, requires management to make estimates and assumptions that affect the reported amounts of revenue, expenses, assets and liabilities, and disclosure of contingent assets and liabilities. The Company regularly assesses these estimates; however, actual results could differ from those estimates. We base our estimates on historical experience, currently available information, and various other assumptions that we believe are reasonable under the circumstances.

Management evaluates these estimates and assumptions on an ongoing basis, including those relating to revenue recognition on cost estimation on certain contracts, allowance for credit losses, inventory obsolescence, valuation allowance for deferred tax assets, income taxes, certain assumptions related to stock-based compensation, impairment of intangible assets and goodwill, restructuring expense accruals, and contingencies. Actual results could differ from these estimates. The impact of changes in estimates is recorded in the period in which they become known.

Restructuring Expenses

As disclosed in the Company's recent Annual Report on Form 10-K for the year ended December 31, 2025, in the fourth quarter of 2025, the Company committed to a restructuring plan as part of its efforts to streamline operations and to align people, roles and projects to our strategic priorities ("2025 restructuring plan"). The 2025 restructuring plan reduced the Company's workforce, with the affected employees separating from the business through the third quarter of 2026. The actions under this restructuring plan were completed and substantially paid through the third quarter of 2026. Total restructuring expenses incurred under the 2025 restructuring plan were $1.5 million.

Recent Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03, "Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Topic 220): Disaggregation of Income Statement Expenses." This standard requires additional disclosure of certain amounts included in the expense captions presented on the statement of operations, as well as disclosures about selling expenses. The ASU is effective on a prospective basis, with the option for retrospective application. All public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. We are currently assessing the impact of adopting this ASU on our unaudited consolidated financial statements.

In July 2025, the FASB issued ASU 2025-05, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets.” This standard provides simplified guidance on measuring credit losses for accounts receivable and contract assets. The update introduces a practical expedient and an accounting policy election to ease the process. All entities can elect the practical expedient to assume that the current economic conditions at the balance sheet date will remain constant through the life of the current receivables and contract assets. Entities that elect the practical expedient and the accounting policy election should apply the amendments in this ASU prospectively. The ASU was effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods, with early adoption permitted. We adopted the standard in the first quarter of 2026 and the adoption did not have a material impact on our unaudited consolidated financial statements.

In September 2025, the FASB issued ASU 2025-06, "Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting of Internal-Use Software." This standard provides a simplified, consistent way to track expenses related to software developed for internal use. The amendments in this standard removed all references to project stages; instead, a company can capitalize software costs once both conditions are met: the entity's management has authorized and committed to funding the project, and it is probable that the project will be completed and the software will be used as intended. The amendments will be effective for annual reporting periods, including interim periods within those years, beginning after December 15, 2027, with early adoption permitted. We are currently assessing the impact of adopting this ASU on our unaudited consolidated financial statements.

In December 2025, the FASB issued ASU 2025-11, "Interim Reporting (Topic 270): Narrow-Scope Improvements," which was intended to improve the navigability of the guidance in ASC 270 and clarify when it applies. Public entities are required to adopt the guidance for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. We are currently assessing the impact of adopting this ASU on our unaudited consolidated financial statements.

In December 2025, the FASB issued ASU 2025-12, "Codification Improvement." This ASU includes a number of improvements that span a wide range of topics, including amendments to the following provisions, among other things: (1) clarify diluted earnings per share ("EPS") calculation when a loss from continuing operations exists; (2) revise the calculation of the reference amount for beneficial interests to prevent double counting credit losses; (3) clarify the permissible methods to account for treasury stock retirements; and (4) clarify the guidance for transfers of receivables from contracts with customers. The standard will be effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods, with early adoption permitted. We are currently assessing the impact of adopting this ASU on our unaudited consolidated financial statements.

In addition, from time to time, new accounting standards are issued by the Financial Accounting Standards Board or other standard-setting bodies and are adopted by the Company as of the specified accounting date. Unless otherwise discussed, the Company believes that issued standards not yet effective will not have a material effect on its financial statements.
