Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements include the accounts of DLH Holdings Corp. and its wholly-owned subsidiaries ("DLH" or the "Company" and also referred to as "we," "us" and "our"). All significant intercompany balances and transactions have been eliminated in consolidation. The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, these statements do not include all of the information and footnotes required by GAAP for complete financial statements. Certain prior year amounts have been reclassified to conform to the fiscal 2026 presentation.

Operating results for the six months ended March 31, 2026 are not necessarily indicative of the results that may be expected for the year ending September 30, 2026 or any future period. Amounts as of March 31, 2026 and for the three and six months ended March 31, 2026 are unaudited. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company's Annual Report on Form 10-K for the year ended September 30, 2025 filed with the Securities and Exchange Commission on December 10, 2025.
