Public Storage is a real estate investment trust that owns and operates self-storage facilities across the United States, leasing storage units of varying sizes to individual consumers and small businesses seeking temporary or long-term storage solutions. The company generates revenue primarily through monthly rental income from tenants, supplemented by ancillary services including tenant reinsurance operations, third-party property management for unrelated facilities, and merchandise sales. Public Storage grows its portfolio through acquisitions, new property development, and expansions of existing facilities, while deploying a balanced strategy of occupancy rates and rental pricing to maximize revenues, and maintaining a strong balance sheet as a REIT that distributes substantially all taxable income to shareholders.
