About PS Business Parks, Inc./md

PS Business Parks, Inc./MD (ticker PSB) was a U.S.-listed real estate company that traded on the NYSE and was organized in 1990. Its principal executive offices were in Glendale, California, at 701 Western Avenue, Glendale, CA 91201, before the company was taken private through its merger with Blackstone in July 2022. For investors, PSB was best understood as a niche REIT with a long history in business-park real estate rather than a traditional downtown office landlord. The company acquired, developed, owned, and operated commercial properties, with a portfolio focused on multi-tenant industrial, industrial-flex, and low-rise suburban office space.

PSB’s assets were positioned in major coastal U.S. markets, an important strategic feature because these locations can support stronger land values, denser tenant demand, and better long-term replacement economics. Public filings and company materials described a portfolio spread across California, Texas, Virginia, Florida, Maryland, and Washington state. At the time it was public, PSB operated roughly 96 to 97 properties and approximately 27 to 28 million rentable square feet, serving around 5,000 tenants. That scale made the company a meaningful mid-cap REIT in the U.S. market, while still preserving a specialized focus on business parks and flexible space.

Its multi-tenant structure helped reduce concentration risk, while its focus on flexible industrial and suburban office space gave it exposure to demand segments tied to small and mid-sized businesses, light manufacturing, service users, and logistics-oriented tenants. Compared with larger industrial REITs, PSB was less of a pure e-commerce warehouse play and more of a diversified owner of infill-style commercial real estate. That positioning generally appealed to investors looking for stable occupancy, recurring rental income, and a portfolio with embedded real-estate optionality in supply-constrained coastal markets.

The deal was announced in April 2022, and PSB shareholders approved it in July 2022; the transaction closed on July 20, 2022, for an equity value reported at about $7.6 billion. As a result, PSB is no longer an independently traded public company, so any current SEC Form 4 context should be interpreted in light of the company’s historical filings rather than ongoing public-market operations. For French-, Belgian-, and Swiss-based investors, the key takeaway is that PSB was once a NYSE-listed U.S. REIT with a specialized business-park franchise, but its public-market story ended with the Blackstone acquisition.
