Re: Proposal 1 – Election of Directors

May 8, 2025

Dear Easterly Government Properties, Inc. Stockholder:

At the 2025 annual meeting of stockholders of Easterly Government Properties, Inc. (the “Company”), our stockholders will vote for the election of the Company’s Board of Directors (the “Board”). Our Board has recommended that the stockholders vote for each of the incumbent directors, per the definitive proxy statement on Schedule 14A (the “Proxy Statement”) filed with the Securities and Exchange Commission on April 18, 2025.

Institutional Shareholder Services (“ISS”) has recommended that stockholders vote against the Company’s directors due to the implementation of the Company’s reverse stock split of its issued and outstanding common stock on April 28, 2025, without a proportionate reduction in authorized shares of common stock. In consultation with our advisors, we did not see a substantive business rationale in making any adjustments to the authorized shares.

As a result, on May 6, 2025, the Board approved an amendment to our charter reducing the authorized shares of common stock, from 200,000,000 to 80,000,000. The amendment was filed following such approval and became effective upon filing. We believe that this amendment satisfies ISS’s concerns regarding our number of authorized shares.

We encourage stockholders to vote FOR each of the directors presented in the Proxy Statement.
