Overview
We are a fully integrated, self-administered and self-managed real estate investment trust (“REIT”), formed as a Maryland corporation on April 30, 2004, to own, operate, manage, acquire, develop and redevelop self-storage properties (“stores”). We closed our initial public offering on August 17, 2004. Our common stock is traded on the New York Stock Exchange under the symbol “EXR.”
We were formed to continue the business of Extra Space Storage LLC and its subsidiaries, which had engaged in the self-storage business since 1977. As of June 30, 2024, we owned or had ownership interests in 2,389 operating stores. Of these stores, 1,912 were wholly-owned, five were in consolidated joint ventures, and 472 were in unconsolidated joint ventures. In addition, as of June 30, 2024, we managed an additional 1,423 stores for third parties bringing the total number of stores which we owned and/or managed to 3,812. These stores are located in 42 states and Washington, D.C.
We operate in two distinct segments: (1) self-storage operations; and (2) tenant reinsurance. Our self-storage operations activities include rental operations of wholly-owned stores and self-storage units. Tenant reinsurance activities include the reinsurance of risks relating to the loss of goods stored by tenants in our stores.
Substantially all of our business is conducted through our operating partnership. Our primary assets are general partner and limited partner interests in our operating partnership. This structure is commonly referred to as an umbrella partnership REIT (“UPREIT”). Between our general partner and limited partner interests, we held a 95.5% majority ownership interest in our operating partnership as of June 30, 2024. We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). To the extent we continue to qualify as a REIT we will not be subject to U.S. federal tax, with certain exceptions, on our net taxable income that is distributed to our stockholders.
Our primary business objectives are to maximize cash flow available for distribution to our stockholders and to achieve sustainable long-term growth in cash flow per share in order to maximize long-term stockholder value both at acceptable levels of risk. We continue to evaluate a range of growth initiatives and opportunities.
Our principal corporate offices are located at 2795 East Cottonwood Parkway, Suite 300, Salt Lake City, Utah 84121, and our telephone number is (801) 365-4600. We maintain a website that contains information about us at www.extraspace.com.
