Global Self Storage Business Summary

Global Self Storage, Inc. (SELF) operates as a self-administered and self-managed Real Estate Investment Trust (REIT) primarily focused on the ownership, operation, and acquisition of self-storage facilities across the United States. The company generates high-margin recurring revenue through a subscription-based model, utilizing month-to-month leases for its primary business segment: Rental Operations. This segment encompasses a diverse portfolio of traditional units, climate-controlled spaces, and specialized outdoor or covered storage for automobiles, RVs, and boats. As of early 2026, the company manages approximately 13 properties across states including New York, Pennsylvania, Illinois, and South Carolina. Within the competitive landscape, SELF competes against industry giants such as Public Storage (PSA), Extra Space Storage (EXR), CubeSmart (CUBE), and National Storage Affiliates Trust (NSA). Positioned as a specialized small-cap micro-REIT, SELF differentiates itself by targeting supply-constrained secondary and tertiary markets where it can achieve higher yields relative to the larger, nationally diversified players. The leadership team is anchored by Executive Chairman, President, and CEO Mark C. Winmill, who has spearheaded the company’s strategic direction since 2012 and brings over 36 years of real estate investment experience, including his tenure as founder and CEO of Bull & Bear Securities. He is supported by Thomas F. O’Malley, CPA, who serves as Chief Financial Officer and Senior Vice President, leveraging over 30 years of financial expertise from roles at Reich & Tang and RSM. Other key executives include Donald Klimoski II, Esq., who oversees legal and operational compliance as General Counsel and SVP of Operations. The company’s Board of Directors includes seasoned professionals such as Sally C. Carroll, Esq., and Russell E. Burke III, following the late 2025 resignation of Thomas B. Winmill. Notable institutional backing is provided by major investors including Vanguard Fiduciary Trust Co., Dimensional Fund Advisors, and Easterly Investment Partners, reflecting a stable institutional ownership base for a micro-cap entity.
