Third Quarter 2025 Supplemental .2

Disclaimers Forward-Looking Statements Certain statements contained in this supplemental, filed in conjunction with the Third Quarter 2025 Earnings Press Release, including statements relating to American Healthcare REIT, Inc.'s (the "Company") expectations regarding its performance, interest expense savings, balance sheet, net income or loss attributable to common shareholders and per diluted share, NAREIT FFO attributable to common shareholders and per diluted share, NFFO attributable to common shareholders and per diluted share, NOI growth, total portfolio Same-Store NOI growth, segment-level Same-Store NOI growth or decline, occupancy, revenue growth, margin expansion, purchases and sales of assets, development plans, and plans for Trilogy 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.

AL: Assisted living units. Annualized Adjusted EBITDA: Current period (shown as quarterly) Adjusted EBITDA multiplied by 4. Annualized Base Rent or ABR: Contractual base rent for the last month of the applicable period multiplied by 12. Cash NOI: NOI excluding the impact of, without duplication, (1) non-cash items such as straight-line rent and the amortization of lease intangibles, (2) third-party facility rent payments and (3) other items set forth in the Cash NOI reconciliation included herein. Both Cash NOI and Same-Store NOI include Pro-Rata ownership and other adjustments. • • EBITDA: A non-GAAP financial measure that is defined as earnings before interest, taxes, depreciation and amortization. EBITDAR: Earnings before interest, taxes, depreciation, amortization and facilities rent. We use unaudited, periodic financial information provided solely by tenants to calculate EBITDAR and have not independently verified the information. • • • • EBITDAR Coverage: The ratio of EBITDAR to contractual rent for leases or interest and principal payments for loans. EBITDAR Coverage is a measure of a property’s ability to generate sufficient cash flows for the operator/borrower to pay rent and meet other obligations. EBITDARM: Earnings before interest, taxes, depreciation, amortization, facilities rent and management fees. We use unaudited, periodic financial information provided solely by tenants to calculate EBITDARM and have not independently verified the information. EBITDARM Coverage: The ratio of EBITDARM to contractual rent for leases or interest and principal payments for loans. EBITDARM Coverage is a measure of a property’s ability to generate sufficient cash flows for the operator or borrower to pay rent and meet other obligations, assuming that management fees are not paid. GAAP revenue: Revenue recognized in accordance with Generally Accepted Accounting Principles (“GAAP”), which includes straight line rent and other non-cash adjustments. • • GLA: Gross leasable area.

Integrated Senior Health Campuses or ISHC: Integrated senior health campuses include a range of senior care, including independent living, assisted living, memory care, skilled nursing services and certain ancillary businesses. Integrated senior health campuses are operated utilizing a RIDEA structure. Maintenance Capex: AHR-invested capital expenditures, whether routine or non-routine (including second generation tenant incentives and leasing commissions), that are not expected to generate incremental income for the Company. • • • MC: Memory-care units. NAREIT FFO or FFO: Funds from operations attributable to controlling interest; a non-GAAP financial measure, consistent with the standards established by the White Paper on FFO approved by the Board of Governors of NAREIT (the “White Paper”). The White Paper defines FFO as net income (loss) computed in accordance with GAAP, excluding gains or losses from sales of certain real estate assets, gains or losses upon consolidation of a previously held equity interest, and impairment write-downs of certain real estate assets and investments, plus depreciation and amortization related to real estate, after adjustments for unconsolidated partnerships and joint ventures. While impairment charges are excluded from the calculation of FFO as described above, investors are cautioned that impairments are based on estimated future undiscounted cash flows. Adjustments for unconsolidated partnerships and joint ventures are calculated to reflect FFO. NAV: Net asset value. • • Net Debt: Total long-term debt, excluding operating lease liabilities, less cash and cash equivalents and restricted cash related to debt. 30

Defined Terms • NOI: Net operating income; a non-GAAP financial measure that is defined as net income (loss), computed in accordance with GAAP, generated from properties before general and administrative expenses, transaction, transition and restructuring costs, depreciation and amortization, interest expense, gain or loss in fair value of derivative financial instruments, gain or loss on dispositions, impairments of real estate investments, impairments of intangible assets and goodwill, income or loss from unconsolidated entities, gain on re-measurement of previously held equity interest, foreign currency gain or loss, other income or expense and income tax benefit or expense. • • NOI margin: Calculated by dividing NOI by revenue.

Occupancy: With respect to OM, the percentage of total rentable square feet leased and occupied, including month-to-month leases, as of the date reported. With respect to all other property types, occupancy represents average quarterly operating occupancy based on the most recent quarter of available data. The Company uses unaudited, periodic financial information provided solely by tenants to calculate occupancy and has not independently verified the information. • • OM: Outpatient Medical buildings. OP Unit: Units of limited partnership interest in the Operating Partnership, which are redeemable for cash or, at our election, shares of our common stock on a one-for- one basis, subject to certain adjustments. • • Operating Partnership: American Healthcare REIT Holdings, LP, a Delaware limited partnership, through which we conduct substantially all of our business and of which Continental Merger Sub, LLC, a Delaware limited liability company and our wholly-owned subsidiary, is the sole general partner. Pro-Rata: As of September 30, 2025, we owned and/or operated six other buildings through entities of which we owned between 90.0% and 90.6% of the ownership interests. Because we have a controlling interest in these entities, these entities and the properties these entities own are consolidated in our financial statements in accordance with GAAP. However, while such properties are presented in our financial statements on a consolidated basis, we are only entitled to our Pro-Rata share of the net cash flows generated by such properties. As a result, we have presented certain property information herein based on our Pro-Rata ownership interest in these entities and the properties these entities own, as of the applicable date, and not on a consolidated basis. In such instances, information is noted as being presented on a “Pro-Rata share” basis. • • Quality Mix: Total number of Medicare, Managed Care, Medicare Advantage and private days or revenue divided by the total number of actual patient days or total revenue for all payor types within Skilled Nursing and Senior Housing beds in the ISHC segment. Retention: The ratio of total renewed square feet and month-to-month leases retained to the total square feet expiring, excluding the square feet for tenant leases terminated and leases in assets expected to be sold for the trailing 12-months. • • RevPOR: Revenue per occupied room. RevPOR is calculated as total revenue generated by occupied rooms divided by the number of occupied rooms. RIDEA: Used to describe properties within the portfolio that utilize the RIDEA structure as described in “RIDEA structure”. 31

Defined Terms • RIDEA structure: A structure permitted by the REIT Investment Diversification and Empowerment Act of 2007, pursuant to which we lease certain healthcare real estate properties to a wholly-owned taxable REIT subsidiary (TRS), which in turn contracts with an eligible independent contractor (EIK) to operate such properties for a fee. Under this structure, the EIK receives management fees, and the TRS receives revenue from the operation of the healthcare real estate properties and retains, as profit, any revenue remaining after payment of expenses (including intercompany rent paid to us and any taxes at the TRS level) necessary to operate the property.
