Business Description

1. Organization and Description of Business Overview and Background American Healthcare REIT, Inc., a Maryland corporation, is a self-managed real estate investment trust, or REIT, that acquires, owns and operates a diversified portfolio of clinical healthcare real estate properties, focusing primarily on senior housing, skilled nursing facilities, or SNFs, outpatient medical, or OM, buildings and other healthcare-related facilities. We have built a fully-integrated management platform that operates clinical healthcare properties throughout the United States, and in the United Kingdom and the Isle of Man. We own and operate our integrated senior health campuses, or ISHC, and senior housing operating properties, or SHOP, utilizing the structure permitted by the REIT Investment Diversification and Empowerment Act of 2007, which is commonly referred to as a “RIDEA” structure. We have also originated and acquired secured loans and may acquire other real estate-related investments in the future on an infrequent and opportunistic basis. We generally seek investments that produce current income; however, we have selectively developed, and may continue to selectively develop, healthcare real estate properties. We have elected to be taxed as a REIT for U.S. federal income tax purposes. We believe that we have been organized and operated, and we intend to continue to operate, in conformity with the requirements for qualification and taxation as a REIT under the Internal Revenue Code of 1986, or the Code. Operating Partnership We conduct substantially all of our operations through American Healthcare REIT Holdings, LP, or our operating partnership, and we are the sole general partner of our operating partnership. As of December 31, 2025 and 2024 , we owned 99.0 % and 98.7 % , respectively, of the operating partnership units, or OP units, in our operating partnership, and the remaining 1.0 % and 1.3 % of the OP units, respectively, were owned by the following limited partners: (i) AHI Group Holdings, LLC, which is owned and controlled by Jeffrey T. Hanson, our Chairman of the Board of Directors and Interim Chief Executive Officer and President, Danny Prosky, our Chief Executive Officer, President and director, who, as previously disclosed, is currently taking a leave of absence from his executive role for medical reasons, and Mathieu B. Streiff, one of our non-executive directors; and (ii) a wholly-owned subsidiary of Griffin Capital Company, LLC, or Griffin Capital. See Note 11, Redeemable Noncontrolling Interests, and Note 12, Equity — Noncontrolling Interests in Total Equity, for a further discussion of the ownership in our operating partnership. Public Offering and Listing On February 9, 2024, pursuant to a Registration Statement filed with the United States Securities and Exchange Commission, or SEC, on Form S-11 (File No. 333-267464), as amended, we closed our underwritten public offering, or the February 2024 Offering, through which we issued 64,400,000 shares of Common Stock, for a total of $ 772,800,000 in gross offering proceeds. Such amounts include the exercise in full of the underwriters’ overallotment option to purchase up to an additional 8,400,000 shares of Common Stock. We listed these shares of Common Stock on the New York Stock Exchange, or NYSE, under the trading symbol “AHR” and began trading on February 7, 2024. Following the closing of the February 2024 Offering and until August 5, 2024, we presented our Common Stock, Class T common stock and Class I common stock, as separate classes of common stock within our consolidated balance sheets and consolidated statements of equity. Any references to Common Stock in this Annual Report on Form 10-K refer to our NYSE-listed shares of common stock, whereas Class T common stock and Class I common stock refer to our historical non-listed shares of common stock. This applies to all historical periods presented herein. On August 5, 2024, 180 days after the listing of our Common Stock on the NYSE, each share of our Class T common stock and Class I common stock automatically converted into one share of our listed Common Stock. See Note 12, Equity — Common Stock, for a further discussion of our public offerings. Our Real Estate Investments Portfolio We currently operate through four reportable business segments: ISHC, OM, SHOP and triple-net leased properties.…
