Ironwood Pharmaceuticals to Relocate to Downtown Boston From Cambridge, to Save $25 Million

100 Summer Street

CAMBRIDGE, MA– Ironwood Pharmaceuticals, Inc., a GI-focused healthcare company,  announced that the company plans to relocate its headquarters to a new office in downtown Boston from its current location in Cambridge, MaA.

Ironwood’s new headquarters will occupy approximately 39,000 square feet at 100 Summer Street. Ironwood anticipates the move to be completed in the fourth quarter of 2019, and expects to save more than $25 million in cash payments to its landlord over the following five years.

“2019 has been a transformative year for Ironwood and this move is the next step in our evolution as we celebrate our new beginning as a streamlined, GI-focused company,” said Mark Mallon, chief executive officer of Ironwood. “We look forward to writing the next chapter in our trajectory as part of Boston’s vibrant business community, which is home to a growing number of innovative biotechnology and pharmaceutical companies. We believe our new space will provide an inspiring work environment for employees, helping to foster a strong culture of innovation and collaboration as we seek to deliver on our mission to develop and commercialize medicines that make a difference for people living with GI diseases.”

The new Boston headquarters is sized to fit the current employee base following completion of the separation of Cyclerion Therapeutics, Inc. on April 1, 2019. The new location is more convenient and centrally located, with easy access to Interstate 93, the Massachusetts Turnpike, Logan International Airport and South Station. Ironwood has signed a multi-year lease into 2030 for the new location. Ironwood currently occupies approximately 108,000 square feet of office space located at 301 Binney Street in Cambridge, Massachusetts.
