Seres Therapeutics entered into a Third Amendment to Lease and Termination Agreement with landlord BMR-Sidney Research Campus LLC on July 31, 2026, ending its lease at 200 Sidney Street in Cambridge, Massachusetts roughly four years ahead of schedule. The company said the deal reduces its ongoing annual facilities costs and materially eliminates its primary restoration obligations. Effective August 1, 2026, Seres surrenders approximately 21,295 rentable square feet, and the remaining 47,341 square feet now expire December 31, 2026 instead of January 13, 2031.
