Auditor Opinion

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of NNN REIT, Inc. and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of income and comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and financial statement schedules listed in the Index at Item 15 (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 11, 2026 expressed an unqualified opinion thereon.
