PS Business Parks, Inc. (PSB) operates as a fully integrated, self-managed real estate investment trust that acquires, develops, owns and manages commercial properties, primarily multi-tenant industrial, flex, business park, low-rise suburban office and multifamily spaces; its portfolio comprises approximately 27 million rentable square feet across 96 properties serving around 4,900 tenants, with additional residential units including a 395-unit apartment complex and a 411-unit development. The company targets coastal markets and serves diverse customers in sectors such as logistics and general business, with operations spanning California, Texas, Virginia, Maryland, Florida and Washington state. Founded in 1986 as a division of Public Storage and spun off as an independent REIT in 1998, PS Business Parks maintains headquarters in Glendale, California. In a major strategic shift, affiliates of Blackstone Real Estate completed the acquisition of PS Business Parks in July 2022 for $7.6 billion in an all-cash deal at $187.50 per share, taking the company private and delisting it from the NYSE; preferred shares remain publicly traded, and Blackstone has since integrated the assets into its broader real estate platform focused on high-growth areas like logistics, data centers and rental housing, with no significant further acquisitions, partnerships or product launches reported through 2025.
