What Global Self Storage, Inc. does

In the company’s own words

Global Self Storage, Inc. (NASDAQ: SELF) operates as a self-administered and self-managed real estate investment trust focused on acquiring, owning, operating, and redeveloping self storage properties across the United States. The company maintains its corporate presence at www.GlobalSelfStorage.us.

As of December 31, 2025, Global Self Storage owns and operates or manages thirteen self storage facilities located in Connecticut, Illinois, Indiana, New York, Ohio, Pennsylvania, South Carolina, and Oklahoma. These properties collectively comprise 966,567 net leasable square feet and offer 7,044 storage units. The company employs 36 total employees and manages its operations through wholly owned subsidiaries. In addition to traditional and climate-controlled storage units, many properties feature covered and outside auto, recreational vehicle, and boat storage options.

The company's business model centers on maximizing financial performance through proprietary revenue rate management systems, digital marketing initiatives, and tenant quality focus. Global Self Storage targets secondary and tertiary markets in the Midwest, Northeast, and Mid-Atlantic regions where barriers to entry for new self storage development are relatively high due to strict zoning laws and planning board requirements. The company strategically positions properties in densely populated, high-traffic areas near major roads and highways with prominent road signage and LED marquee boards.

Global Self Storage has elected to be taxed as a real estate investment trust under the Internal Revenue Code, commencing with its taxable year ended December 31, 2013. The company was incorporated in Maryland on December 12, 1996, and previously operated as an investment company under the Investment Company Act of 1940 before transitioning to an operating company in January 2016. The company changed its name from Self Storage Group, Inc. to Global Self Storage, Inc. and listed its common stock on NASDAQ under the symbol SELF.

Beyond its core self storage operations, Global Self Storage established a third-party management platform, managing one property in Edmond, Oklahoma, comprising 137,318 leasable square feet and 619 climate-controlled and non-climate-controlled units. The company pursues acquisition opportunities strategically while maintaining disciplined underwriting standards and employs various financing alternatives including debt offerings, equity offerings, credit facilities, mortgage financing, and joint ventures to support growth initiatives.
