We also operate healthcare-related facilities utilizing the structure permitted by the REIT Investment Diversification and Empowerment Act of 2007, which is commonly referred to as a “RIDEA” structure (the provisions of the Internal Revenue Code of 1986, as amended, or the Code, authorizing the RIDEA structure were enacted as part of the Housing and Economic Recovery Act of 2008). Our healthcare facilities operated under a RIDEA structure include our senior housing operating properties, or SHOP (formerly known as senior housing — RIDEA), and our integrated senior health campuses. We have originated and acquired secured loans and may also originate and acquire other real estate-related investments 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, real estate properties. We qualified to be taxed as a real estate investment trust, or REIT, under the Code for federal income tax purposes, and we intend to continue to qualify to be taxed as a REIT. </span></div><div style="margin-top:9pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Merger of Griffin-American Healthcare REIT III, Inc. and Griffin-American Healthcare REIT IV, Inc.</span></div><div style="margin-top:9pt;text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">On June 23, 2021, Griffin-American Healthcare REIT III, Inc., a Maryland corporation, or GAHR III, Griffin-American Healthcare REIT III Holdings, LP, a Delaware limited partnership, or our operating partnership that subsequent to the Merger on October 1, 2021 described below is also referred to as the surviving partnership, Griffin-American Healthcare REIT IV, Inc., a Maryland corporation, or GAHR IV, its subsidiary Griffin-American Healthcare REIT IV Holdings, LP, a Delaware limited partnership, or GAHR IV Operating Partnership, and Continental Merger Sub, LLC, a Maryland limited liability company and a newly formed wholly owned subsidiary of GAHR IV, or Merger Sub, entered into an Agreement and Plan of Merger, or the Merger Agreement. On October 1, 2021, pursuant to the Merger Agreement, (i) GAHR III merged with and into Merger Sub, with Merger Sub being the surviving company, or the REIT Merger, and (ii) GAHR IV Operating Partnership merged with and into our operating partnership, with our operating partnership being the surviving entity and being renamed American Healthcare REIT Holdings, LP, or the Partnership Merger, and, together with the REIT Merger, the Merger. Following the Merger on October 1, 2021, our company, or the Combined Company, was renamed American Healthcare REIT, Inc. The REIT Merger was intended to qualify as a reorganization under, and within the meaning of, Section 368(a) of the Code. As a result of and at the effective time of the Merger, the separate corporate existence of GAHR III and GAHR IV Operating Partnership ceased.</span></div><div style="margin-top:8pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:107%">AHI Acquisition</span></div><div style="margin-top:8pt;text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Also on June 23, 2021, GAHR III; our operating partnership; American Healthcare Investors, LLC, or AHI; Griffin Capital Company, LLC, or Griffin Capital; Platform Healthcare Investor T-II, LLC; Flaherty Trust; and Jeffrey T.

Streiff, our former Executive Vice President, General Counsel and current Chief Operating Officer, or collectively, the AHI Principals, entered into a contribution and exchange agreement, or the Contribution Agreement, pursuant to which, among other things, GAHR III agreed to acquire a newly formed entity, American Healthcare Opps Holdings, LLC, or NewCo, which we refer to as the AHI Acquisition. NewCo owned substantially all of the business and operations of AHI, as well as all of the equity interests in (i) Griffin-American Healthcare REIT IV Advisor, LLC, or GAHR IV Advisor, a subsidiary of AHI that served as the external advisor of GAHR IV, and (ii) Griffin-American Healthcare REIT III Advisor, LLC, or GAHR III Advisor, also referred to as our former advisor, a subsidiary of AHI that served as the external advisor of GAHR III.

In exchange for these contributions, the surviving partnership issued limited partnership units, or surviving partnership OP units. Subject to working capital and other customary adjustments, the total approximate value of these surviving partnership OP units at the time of consummation of the transactions contemplated by the Contribution Agreement was approximately $131,674,000, with a reference value for purposes thereof of $8.71 per unit, such that the surviving partnership issued 15,117,529 surviving partnership OP units as consideration, or the Closing Date Consideration. Following the consummation of the Merger and the AHI Acquisition, the Combined Company has become self-managed. As of December 31, 2021, such surviving partnership OP units are owned by AHI Group Holdings, LLC, or AHI Group Holdings, which is owned and controlled by the AHI Principals, Platform Healthcare Investor T-II, LLC, Flaherty Trust and a wholly owned subsidiary of Griffin Capital, or collectively, the NewCo Sellers. </span></div><div style="margin-top:8pt;text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In addition to the Closing Date Consideration, pursuant to the Contribution Agreement, we may in the future pay cash “earnout” consideration to AHI based on the fees that we may earn from our potential sponsorship of, and investment advisory services rendered to, American Healthcare RE Fund, L.P., a healthcare-related, real-estate-focused, private investment fund under consideration by AHI, or the Earnout Consideration. The Earnout Consideration is uncapped in amount and, if ever payable by us to AHI, will be due on the seventh anniversary of the closing of the AHI Acquisition (subject to acceleration in certain events, including if we achieve certain fee-generation milestones from our sponsorship of the private investment fund). AHI’s ability to receive the Earnout Consideration is also subject to vesting conditions relating to the private investment fund’s deployed equity capital and the continuous employment of at least two of the AHI Principals throughout the vesting period. As of December 31, 2021, the fair value of such cash earnout consideration was estimated to be $0.</span></div><div style="margin-top:8pt;text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The AHI Acquisition was treated as a business combination for accounting purposes, with GAHR III as both the legal and accounting acquiror of NewCo. While GAHR IV was the legal acquiror of GAHR III in the REIT Merger, GAHR III was determined to be the accounting acquiror in the REIT Merger in accordance with Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 805, </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Business Combinations</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">, or ASC Topic 805, after considering the relative share ownership and the composition of the governing body of the Combined Company.

Our former advisor used its best efforts, subject to the oversight and review of our board of directors, or our board, to, among other things, provide asset management, property management, acquisition, disposition and other advisory services on our behalf consistent with our investment policies and objectives. Following the Merger and AHI Acquisition, we became self-managed and are no longer externally advised.

A total of $245,396,000 in distributions were reinvested that resulted in 26,386,545 shares of common stock being issued pursuant to the 2015 GAHR III DRIP Offering.</span></div><div style="margin-top:8pt;text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">On January 30, 2019, we filed a Registration Statement on Form S-3 under the Securities Act of 1933, as amended, or the Securities Act, to register a maximum of $200,000,000 of additional shares of our common stock to be issued pursuant to the Amended and Restated DRIP, or the 2019 GAHR III DRIP Offering, which commenced on April 1, 2019, following the deregistration of the 2015 GAHR III DRIP Offering. On May 29, 2020, in consideration of the impact the coronavirus, or COVID-19, pandemic had on the United States, globally and on our business operations, our board authorized the suspension of the 2019 GAHR III DRIP Offering. Such suspension was effective upon the completion of all shares issued with respect to distributions payable to stockholders of record on or prior to the close of business on May 31, 2020. A total of $63,105,000 in distributions were reinvested that resulted in 6,724,348 shares of common stock being issued pursuant to the 2019 GAHR III DRIP Offering. </span></div><div style="margin-top:8pt;text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">As a result of the Merger, we deregistered the 2019 GAHR III DRIP Offering.

We continue to offer up to $100,000,000 of shares of our common stock to be issued pursuant to the DRIP under an existing Registration Statement on Form S-3 under the Securities Act filed by GAHR IV, or the AHR DRIP Offering. We collectively refer to the Initial DRIP portion of the GAHR III initial offering, the 2015 GAHR III DRIP Offering, the 2019 GAHR III DRIP Offering and the AHR DRIP Offering as our DRIP Offerings. See Note 14, Equity — Distribution Reinvestment Plan, for a further discussion. As of December 31, 2021, a total of $54,637,000 in distributions were reinvested that resulted in 5,755,013 shares of common stock being issued pursuant to the AHR DRIP Offering. </span></div><div style="margin-top:8pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Our Real Estate Investments Portfolio</span></div><div style="margin-top:8pt;text-indent:24.75pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We currently operate through six reportable business segments: medical office buildings, integrated senior health campuses, skilled nursing facilities, SHOP, senior housing and hospitals.

The rise of the Delta and Omicron variants of COVID-19, and government and public health agencies’ responses to potential future resurgences in the virus, further contributes to the prolonged economic impact and uncertainties caused by the COVID-19 pandemic. There is also uncertainty regarding the acceptance of available vaccines and boosters and the public’s receptiveness to those measures. As the COVID-19 pandemic is still impacting the healthcare system, it continues to present challenges for us as an owner and operator of healthcare facilities, making it difficult to ascertain the long-term impact the COVID-19 pandemic will have on real estate markets in which we own and/or operate properties and our portfolio of investments. </span></div><div style="margin-top:8pt;text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We have evaluated the impacts of the COVID-19 pandemic on our business thus far and incorporated information concerning such impacts into our assessments of liquidity, impairment and collectability from tenants and residents as of December 31, 2021.

We adopted ASC Topic 326 using the modified retrospective approach whereby the cumulative effect of adoption was recognized on the adoption date and prior periods were not restated. There was no net cumulative effect adjustment to retained earnings as of January 1, 2020. Resident receivables are carried net of an allowance for credit losses. An allowance is maintained for estimated losses resulting from the inability of residents and payors to meet the contractual obligations under their lease or service agreements. Substantially all of such allowances are recorded as direct reductions of resident fees and services revenue as contractual adjustments provided to third-party payors or implicit price concessions in our accompanying consolidated statements of operations and comprehensive income (loss). Our determination of the adequacy of these allowances is based primarily upon evaluations of historical loss experience, the residents’ financial condition, security deposits, cash collection patterns by payor and by state, current economic conditions, future expectations in estimating credit losses and other relevant factors. Prior to our adoption of ASC Topic 326 on January 1, 2020, resident receivables were carried net of an allowance for uncollectible amounts. Tenant receivables and unbilled deferred rent receivables are reduced for uncollectible amounts, which are recognized as direct reductions of real estate revenue in our accompanying consolidated statements of operations and comprehensive income (loss).</span></div>
