Office Properties Income Trust is a Maryland-organized real estate investment trust (REIT) focused on owning and leasing high-quality office and mixed-use properties across the United States. Founded in 2009 as Government Properties Income Trust and taken public in June 2009, the company owns 124 properties totaling approximately 17.2 million square feet across 29 states and Washington D.C., with an occupancy rate of roughly 77.5%. OPI is externally managed by The RMR Group LLC and has no direct employees. Key tenants include the U.S. Government (17.1% of rental income), Alphabet/Google (5.8%), and Bank of America (4.4%), with government tenants overall representing about 25.4% of annualized rental income. The Newton, Massachusetts-based REIT filed for Chapter 11 protection on October 30, 2025 in the Southern District of Texas (Case No. 25-90530) after macroeconomic shifts in office space utilization post-COVID, increased remote work arrangements reducing demand, and a challenging real estate financing environment left the company unable to service its approximately $2.42 billion in funded debt. The capital structure includes a $425 million credit facility, $610 million in September 2029 Notes, $418 million in March 2027 Notes, and approximately $491 million in unsecured notes. An ad hoc group holding approximately 80% of the September 2029 Notes provided a $125 million DIP facility at 12% interest. The Joint Chapter 11 Plan filed January 9, 2026 targets deleveraging to approximately $1.3 billion upon emergence, with a confirmation hearing scheduled for April 20, 2026.
