Description of the Business	1. Description of the Business Public Storage is a Maryland real estate investment trust (“REIT”) engaged in the ownership and operation of self-storage facilities that offer storage spaces for lease, generally on a month-to-month basis, for personal and business use, and other related operations such as tenant reinsurance, merchandise sales, third party management, and bridge lending to third-party self-storage owners, as well as the acquisition and development of additional self-storage space. We are structured as an umbrella partnership REIT, or UPREIT, under which substantially all of our business is conducted through Public Storage OP, L.P. (“PSA OP”), an operating partnership, and its subsidiaries, including Public Storage Operating Company (“PSOC”). The primary assets of the parent entity, Public Storage, are general partner and limited partner interests in PSA OP, which holds all of the Company’s assets through its ownership of all of the equity interests in PSOC. As a limited partnership, PSA OP is a variable interest entity and is consolidated by Public Storage as its primary beneficiary. As of June 30, 2025, Public Storage owned all of the general partner interests and approximately 99.80% of the limited partnership interests of PSA OP, with the remaining 0.20% of limited partnership interests owned by certain trustees and officers of the Company.

In addition, we managed 329 facilities (with approximately 25.4 million net rentable square feet) for third parties at June 30, 2025. At June 30, 2025, we owned an approximate 35% common equity interest in Shurgard Self Storage Limited (“Shurgard”), a public company traded on the Euronext Brussels under the “SHUR” symbol, which owned 321 self-storage facilities (with approximately 18 million net rentable square feet) located in seven Western European countries, all operating under the Shurgard® name. In recording our share of equity in earnings or losses from Shurgard, we adjust Shurgard’s operating results, which are reported under IFRS, to conform with US GAAP.
