EXHIBIT 99.1

Global Self Storage Board of Directors Unanimously Rejects Unsolicited Acquisition Proposal from Etude Storage Partners

MILLBROOK, NY, May 21, 2024 – Global Self Storage, Inc. (NASDAQ: SELF) (the “Company” or “Global Self Storage”), a real estate investment trust that owns, operates, manages, acquires and redevelops self-storage properties, today announced that the Global Self-Storage Board of Directors (the “Board”) unanimously rejected the unsolicited, non-binding, and conditional acquisition proposal that it received from Etude Storage Partners LLC (“Etude”) on May 7, 2024 to acquire all of the outstanding shares of common stock of the Company for $6.15 per share in cash.

The Board, which consists of a majority of independent directors, consistent with its duties under Maryland law and in consultation with its financial and legal advisors, carefully reviewed Etude’s proposal and unanimously determined that such proposal is inadequate and significantly undervalues Global Self Storage and its prospects for growth and value creation, and is not in the best interests of the Company and its stockholders. In addition, the Board unanimously affirmed it is not contemplating a sale of the Company, and unanimously determined that the continued execution of the Company’s strategic business plan is in the best interests of the Company and its stockholders and is more likely than Etude’s proposal to lead to greater long-term value creation for stockholders.

“After a careful and detailed review of Etude’s most recent unsolicited, non-binding, and conditional acquisition proposal, it was clear to our entire Board that Etude’s proposal is a self-interested and opportunistically timed attempt to transfer value to Etude and its principals at the expense of Global Self Storage’s stockholders,” said Mark C. Winmill, President, Chief Executive Officer, Chairman of the Board, and Founder. “Our Board believes that Global Self Storage has significant upside potential and that we can best maximize long-term stockholder value by leveraging our extensive operational expertise in the self-storage industry, our proven track record of financial and operating performance, and our strong capital resources position, brand, and reputation for excellence by continuing to execute our strategic business plan. As such, we are not contemplating a sale of the Company.”

The full text of the letter sent today to Steven Stein, the President of Etude Storage Partners LLC, follows:

May 21, 2024

Dear Mr. Stein:

We are writing in response to your May 7, 2024 unsolicited, non-binding, and conditional acquisition proposal to acquire all of the issued and outstanding shares of Global Self Storage, Inc. for $6.15 per share in cash.

Our Board of Directors, which consists of a majority of independent directors, consistent with its duties under Maryland law and in consultation with its financial and legal advisors, carefully considered your proposal, and unanimously determined that your proposal is inadequate and undervalues Global Self Storage, Inc.’s current and potential long-term value, and is not in the best interests of Global Self Storage, Inc. and its stockholders. Accordingly, our Board rejected your

proposal and continues to believe that the execution of our strategic business plan is in the best interests of Global Self Storage, Inc. and its stockholders.

Sincerely,

/s/ Mark C. Winmill

Mark C. Winmill

Chief Executive Officer, President, and

Chairman of Board of Directors
