Dear Fellow Stockholder:

We are excited to provide you with an important company update regarding Griffin-American Healthcare REIT III, Inc. (“GAHR III”), and the strategic alternatives process initiated by our board of directors in late 2020, details of which we shared with you in our letter dated March 19, 2021 and investor presentation dated April 28, 2021.

GAHR III, Griffin-American Healthcare REIT IV, Inc. (“GAHR IV”), and American Healthcare Investors, LLC (“AHI”) have announced a tri-party transaction which we believe will benefit GAHR III stockholders by creating an improved portfolio with greater scale and increased operating efficiencies that are expected to generate substantial annual cost savings. We believe the combination will position the combined company well for long-term value creation and liquidity.

Proposed Merger

Following a thorough evaluation of potential strategic alternatives, on June 23, 2021, GAHR III entered into a definitive merger agreement pursuant to which the company will be acquired by GAHR IV in a tax-free, stock-for-stock transaction that will create a combined company with a gross investment value1 of approximately $4.2 billion in healthcare real estate assets. Upon completion of the merger (the “REIT merger”), the newly combined company, to be renamed American Healthcare REIT, Inc., will be the 11th largest healthcare-focused real estate investment trust globally.2

Additionally, GAHR III entered into a definitive agreement to acquire substantially all of the business and operations of AHI, one of the co-sponsors of both our company and GAHR IV, including the external advisors of both REITs. This acquisition (the “AHI Acquisition”) is expected to take place just prior to the completion of the REIT merger, although completion of the AHI Acquisition is not a condition to completing the REIT merger.

The result of these transactions would be the creation of a fully integrated, self-managed company with a large and diverse property portfolio led by an experienced management team. Once the transactions are completed, American Healthcare REIT is expected to benefit from annual operational cost savings of approximately $21 million, which will help support an anticipated annual distribution rate of $0.40 per share for the combined company.3

Potential Liquidity/Listing on a National Stock Exchange

The board of directors and the executive management team believe the proposed REIT merger and AHI acquisition would position the combined company for a successful listing on a national stock exchange by the end of 2022.4 We believe a public listing will provide the opportunity for the combined company to enter its next phase by utilizing the public markets for growth capital while also providing liquidity optionality to stockholders. Of course, a listing on a national stock exchange is subject to the closing of the proposed transactions and market conditions and therefore no assurances can be made that a listing will occur within this timeframe, or at all.

Upon completion of these transactions, not only would the combined company be positioned as the 11th largest healthcare-focused REIT globally, but the day we list on a major stock exchange, the company would represent the single largest healthcare REIT listing in the history of the public markets. Management believes that this size and scale will attract significant interest from institutional investors who regularly allocate investment capital into publicly traded REITs.

The proposed transactions are expected to close in the fourth quarter of 2021, subject to certain closing conditions, including the approval of the REIT merger by both GAHR III and GAHR IV stockholders. You will receive additional information regarding this vote in the coming weeks.

We believe this is an exciting prospect for the company and we look toward the future with enthusiasm. As you know, the three founders of AHI are the three largest individual investors in the company, and we stand shoulder-to-shoulder with you.
