Title: 1. BASIS OF PRESENTATION Accounting Policies: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The SEFA has been prepared in accordance with the accrual basis of accounting and with accounting principles generally accepted in the United States of America, and is consistent with the preparation of the Institute’s consolidated financial statements. Amounts reflected in the SEFA include only expenditures of federal awards whereas the corresponding amounts reported in the consolidated financial statements also include expenditures of federal fixed price contracts and nonfederal awards. Such expenditures are recognized following the applicable cost principles wherein certain types of expenditures are unallowable. Negative amounts shown on the SEFA represent adjustments or credits made in the normal course of business to amounts reported as expenditures in prior years. An award is considered expended when the activity related to the award occurs. The activity generally pertains to events requiring compliance with laws, regulations, and the provisions of contract and grant agreements. Direct costs have been recognized on the accrual basis of accounting when costs are incurred. For time and materials contracts, expenditures are recognized as hours and costs are incurred based on negotiated rates. Fees on cost-plus contracts are recognized as costs are incurred and expenditures include a proportionate share of the fees earned. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). The consolidated financial statements include the accounts of the Institute and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated. The preparation of the consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the consolidated financial statements. Actual results could differ from those estimates. De Minimis Rate Used: N Rate Explanation: The Institute has elected not to use the 10-percent de minimis indirect cost rate allowed under the Uniform Guidance. Indirect costs are recovered from the federal government by applying a federally negotiated indirect cost rate or by allocating these costs among benefiting programs in accordance with a federally approved plan. Each program’s share of indirect costs is recognized on the accompanying SEFA. 1. BASIS OF PRESENTATION The schedule of expenditures of federal awards (the “SEFA”) includes the federal award activity of the Research Triangle Institute (the “Institute”) under programs of the federal government for the year ended September 30, 2024. The information in the SEFA is presented in accordance with the requirements of Title 2 U.S. Code of Federal Regulations (“2 CFR”) Part 200, Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards (Uniform Guidance). Because the SEFA presents only a selected portion of the operations of the Institute, it is not intended to and does not present the financial position, changes in net assets, or cash flows of the Institute. Assistance listing numbers (“ALN numbers”) are unique numbers assigned to identify Federal Assistance Listings, the publicly available listing of Federal assistance programs managed and administered by the General Services Administration, formerly known as the Catalog of Federal Domestic Assistance. As provided for in the Uniform Guidance, when no ALN number is assigned, the purpose of federal contracts from the same federal agency is assessed, and those made for the same purpose are combined and considered one program. Programs without an ALN number are presented with only the federal agency’s two-digit prefix followed by the abbreviation “RD” for those programs in the research and development cluster or “U” (i.e. unknown) and sequentially numbered by federal agency in place of an ALN number. The Institute assigns sequential numbers on an annual basis unless a program had already been assigned a number on the SEFA in a prior year. The federal agency two-digit prefixes are as follows: [see Table in Notes to the Schedule of Expenditures of Federal Awards Note 1] SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The SEFA has been prepared in accordance with the accrual basis of accounting and with accounting principles generally accepted in the United States of America, and is consistent with the preparation of the Institute’s consolidated financial statements.

Subsequent to September 30, 2024, and through June 27, 2025, pursuant to executive orders issued by the new U.S. Administration or actions taken by the Department of Government Efficiency (“DOGE”), the Institute received notices for termination-for-convenience of approximately $426.6 million and for stop-work orders of approximately $8.1 million of remaining funded contract value, respectively. Had the terminations-for-convenience occurred prior to September 30, 2024, the aggregate amount of our contract transaction price that remained for future revenue recognition, excluding time and materials and unfunded contract balances, would have been reduced by approximately 21.6%. Further, had these terminations-for-convenience occurred prior to September 30, 2024, the aggregate amount of conditional promises to be received in future years related to the Institute’s ongoing operating programs would have been reduced by approximately 39.4%.
