BASIS OF FINANCIAL STATEMENT PRESENTATION	BASIS OF FINANCIAL STATEMENT PRESENTATION Description of Business Fortrea Holdings Inc. (“Fortrea” or the “Company”), a Delaware corporation incorporated on January 31, 2023, is a leading global contract research organization (“CRO”) providing biopharmaceutical product and medical device development solutions to pharmaceutical, biotechnology and medical device customers. The Company offers customers highly flexible delivery models that include Full Service, Functional Service Provider, and Hybrid Service structures. The Company has a rich history of providing clinical development services for more than 30 years across more than 20 therapeutic areas. The Company leverages its global scale, clinical data insights, scientific and therapeutic expertise, technology innovation, industry network and decades of experience as a standalone company and as a business unit prior to its spin-off from Labcorp Holdings Inc. to deliver tailored solutions to its customers. With what the Company believes is a distinctive market offering, Fortrea meets growing global demand for clinical development services. The Company has established access to all key markets worldwide through a strategic footprint of primary office locations in five countries (the United States, the United Kingdom, China, India and Japan) with field operations in other jurisdictions worldwide. On March 9, 2024, the Company, together with its wholly-owned subsidiary, Fortrea Inc., entered into an Asset Purchase Agreement with Endeavor Buyer LLC, an affiliate of Arsenal Capital Partners, to sell the operations of Fortrea Patient Access Inc. and its subsidiaries and Endpoint Clinical, Inc. and its subsidiaries; which are all collectively referred to as the Enabling Services Segment (the “Transaction”). The final adjusted purchase price for the Transaction was $340.0, subject to customary purchase price adjustments, with $295.0 paid at closing and $45.0 to be paid upon achievement of certain transition-related milestones. The Transaction closed during the second quarter of 2024. The first milestone payment in the amount of $20.0 was received in the first quarter of 2025. The second and final milestone payment in the amount of $25.0 was received in the third quarter of 2025. Reportable Segment The Company manages its business in one reportable segment, Clinical Services, which provides phase I-IV clinical trials, including clinical pharmacology and comprehensive clinical development capabilities. The Company’s chief operating decision maker allocates resources and assesses performance for the Clinical Services segment. For further financial information about the segment, see Note 13, “Business Segment Information”. Unaudited Interim Financial Information The Company’s unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments necessary for a fair statement of results of operations, cash flows, and financial position have been made. Except as otherwise disclosed, all such adjustments are of a normal recurring nature. Interim results are not necessarily indicative of results for a full year. As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company’s audited consolidated and combined financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, accounts receivable and unbilled services. The Company maintains cash and cash equivalents with various major financial institutions. These financial institutions are generally highly rated and geographically dispersed. The Company evaluates the relative credit standing of these financial institutions and has not sustained credit losses from instruments held at financial institutions. Substantially all of the Company’s accounts receivable and unbilled services are with companies in the pharmaceutical, biotechnology and medical device industries. As of March 31, 2026, one pharmaceutical customer accounted for 18.5% of the Company's combined gross accounts receivable and unbilled services. As of December 31, 2025, one pharmaceutical customer accounted for approximately 18.3% of the Company's combined gross accounts receivable and unbilled services. Additionally, for the three months ended March 31, 2026, one customer accounted for approximately 17.2% of revenues. For the three months ended March 31, 2025, one customer accounted for 15.4% of revenues. Concentrations of credit risk are mitigated due to the number of the Company’s customers as well as their dispersion across many different geographic regions. Additionally, the Company applies assumptions and judgments, including historical collection experience and reasonable and supportable forecasts, for assessing collectability and determining allowances for doubtful accounts. Recently Issued and Adopted Accounting Standards In November 2024, the Financial Accounting Standards Board (“FASB”) issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40), Disaggregation of Income Statement Expenses. The new guidance requires disclosure of certain costs and expenses in the notes to the financial statements. This guidance is effective for fiscal years beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The disclosures required under the guidance can be applied either prospectively to financial statements issued for reporting periods after the effective date or retrospectively to any or all periods presented in the financial statements. The Company is currently evaluating the impact this guidance will have on its financial statement disclosures. 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. The new guidance simplifies the accounting for internally developed software by replacing the existing phase-based capitalization model with a principles-based approach that focuses on management’s authorization and the probability of project completion. The guidance is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years. Entities may apply the guidance using a prospective, retrospective, or modified transition approach, and early adoption is permitted. The Company is currently evaluating the impact this guidance will have on its financial statements and disclosures. In December 2025, the FASB issued ASU 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities. This ASU establishes guidance on the recognition, measurement, and presentation of government grants received by business entities. The guidance is intended to improve consistency and transparency by providing a comprehensive accounting framework for government grants under U.S. GAAP. The guidance is effective for fiscal years beginning after December 15, 2028, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact this guidance will have on its financial statements and disclosures.
