First Quarter 2026 Supplemental .2

Disclaimers Forward-Looking Statements Certain statements contained in this supplemental, filed in conjunction with the First Quarter 2026 Earnings Press Release, including statements relating to American Healthcare REIT, Inc.'s (the "Company") expectations regarding its performance, interest expense, balance sheet, net income or loss attributable to common stockholders and per diluted share, NAREIT FFO attributable to common stockholders and per diluted share, NFFO attributable to common stockholders and per diluted share, NOI growth, total portfolio Same-Store NOI growth, segment-level Same-Store NOI growth, Occupancy, revenue growth, purchases and sales of assets, development plans, and the settlement of forward sale agreements may be considered forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. The Company intends for all such forward-looking statements to be covered by the applicable safe harbor provisions for forward-looking statements contained in those acts. Such forward-looking statements generally can be identified by the use of forward-looking terminology such as “may,” “will,” “can,” “expect,” “intend,” “anticipate,” “estimate,” “believe,” “continue,” “possible,” “initiatives,” “focus,” “seek,” “objective,” “goal,” “strategy,” “plan,” “potential,” “potentially,” “preparing,” “projected,” “future,” “long-term,” “once,” “should,” “could,” “would,” “might,” “uncertainty,” or other similar words. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this supplemental. Any such forward-looking statements are based on current expectations, estimates and projections about the industry and markets in which the Company operates and beliefs of, and assumptions made by, the Company's management and involve known and unknown risks and uncertainties that could cause actual results to differ materially from those expressed or implied therein, including, without limitation, changing macroeconomic conditions, domestic legal and fiscal policies, and geopolitical conditions and other risks disclosed in the Company’s periodic reports as filed with the Securities and Exchange Commission. Except as required by law, the Company does not undertake any obligation to update or revise any forward-looking statement. 2

Disclaimers Non-GAAP Financial Measures The Company’s reported results are presented in accordance with GAAP. The Company also discloses the following non-GAAP financial measures: EBITDA, Adjusted EBITDA, Net Debt-to-Annualized Adjusted EBITDA, NAREIT FFO, NFFO, NOI and Same-Store NOI. The Company believes these non-GAAP financial measures are useful supplemental measures of its operating performance and used by investors and analysts to compare the operating performance of the Company between periods and to other REITs or companies on a consistent basis without having to account for differences caused by unanticipated and/or incalculable items. Definitions of the non-GAAP financial measures used herein and reconciliations to the most directly comparable financial measure calculated in accordance with GAAP can be found at the end of this Supplemental. See below for further information regarding the Company's non-GAAP financial measures. EBITDA and Adjusted EBITDA Management uses earnings before interest, taxes, depreciation and amortization (“EBITDA”) and Adjusted EBITDA to facilitate internal and external comparisons to our historical operating results and in making operating decisions. EBITDA and Adjusted EBITDA are widely used by investors, lenders, credit and equity analysts in the valuation, comparison, and investment recommendations of companies. Additionally, EBITDA and Adjusted EBITDA are utilized by our Board of Directors to evaluate management. Neither EBITDA nor Adjusted EBITDA represents net income (loss) or cash flows provided by operating activities as determined in accordance with GAAP and should not be considered as alternative measures of profitability or liquidity. Finally, EBITDA and Adjusted EBITDA may not be comparable to similarly entitled items reported by other REITs or other companies. In addition, management uses Net Debt-to-Annualized Adjusted EBITDA as a measure of our ability to service our debt. NAREIT Funds from Operations (FFO) and Normalized Funds from Operations (NFFO) We believe that the use of FFO, which excludes the impact of real estate-related depreciation and amortization and impairments, provides a further understanding of our operating performance to investors, industry analysts and our management, and when compared year over year, reflects the impact on our operations from trends in Occupancy rates, rental rates, operating costs, general and administrative expenses and interest costs, which may not be immediately apparent from net income (loss) as determined in accordance with GAAP. However, FFO and NFFO should not be construed to be (i) more relevant or accurate than the current GAAP methodology in calculating net income (loss) as an indicator of our operating performance, (ii) more relevant or accurate than GAAP cash flows from operations as an indicator of our liquidity or (iii) indicative of funds available to fund our cash needs, including our ability to make distributions to our stockholders. The method utilized to evaluate the value and performance of real estate under GAAP should be construed as a more relevant measure of operational performance and considered more prominently than the non-GAAP FFO and NFFO measures and the adjustments to GAAP in calculating FFO and NFFO. Presentation of this information is intended to provide useful information to investors, industry analysts and management as they compare the operating performance metrics used by the REIT industry, although it should be noted that some REITs may use different methods of calculating funds from operations and normalized funds from operations, so comparisons with such REITs may not be meaningful. Net Operating Income We believe that NOI, Cash NOI, Pro-Rata Cash NOI and Same-Store NOI are appropriate supplemental performance measures to reflect the performance of our operating assets because NOI, Cash NOI, Pro-Rata Cash NOI and Same-Store NOI exclude certain items that are not associated with the operations of the properties. We believe that NOI, Cash NOI, Pro-Rata Cash NOI and Same-Store NOI are widely accepted measures of comparative operating performance in the real estate community and are useful to investors in understanding the profitability and operating performance of our property portfolio. However, our use of the terms NOI, Cash NOI, Pro-Rata Cash NOI and Same- Store NOI may not be comparable to that of other real estate companies as they may have different methodologies for computing these amounts. NOI, Cash NOI, Pro-Rata Cash NOI and Same-Store NOI are not equivalent to our net income (loss) as determined under GAAP and may not be a useful measure in measuring operational income or cash flows. Furthermore, NOI, Cash NOI, Pro-Rata Cash NOI and Same-Store NOI should not be considered as alternatives to net income (loss) as an indication of our operating performance or as an alternative to cash flows from operations as an indication of our liquidity. NOI, Cash NOI, Pro-Rata Cash NOI and Same-Store NOI should not be construed to be more relevant or accurate than the GAAP methodology in calculating net income (loss). NOI, Cash NOI, Pro-Rata Cash NOI and Same-Store NOI should be reviewed in conjunction with other measurements as an indication of our performance. 3

Actual results may differ materially from the Company's expectations depending on factors discussed herein and in the Company's filings with the Securities and Exchange Commission. Totals may not add due to rounding. Non-GAAP financial measures and other terms, as used in this supplemental, are also defined and further explained in the appendix. The Company is unable to provide, without unreasonable effort, guidance for the most comparable GAAP financial measures of total revenues and property operating and maintenance expenses. Additionally, a reconciliation of the forward-looking non-GAAP financial measures of Same-Store NOI growth to the comparable GAAP financial measures cannot be provided without unreasonable effort because the Company is unable to reasonably predict certain items contained in the GAAP measures, including non-recurring and infrequent items that are not indicative of the Company's ongoing operations. Such items include, but are not limited to, impairment on depreciated real estate assets, net gain or loss on sale of real estate assets, stock-based compensation, casualty loss, non-Same-Store revenue, and non-Same-Store operating expenses. These items are uncertain, depend on various factors, and could have a material impact on the Company's GAAP results for the guidance period. See reconciliations in the appendix of this presentation. (2) Amounts are presented net of noncontrolling interests' share and AHR's share of unconsolidated entities. (3) Amounts represent amortization of equity compensation and fair value adjustments to performance-based equity compensation.
