109 Brookline Ave.

One of Greater Boston’s fastest-growing life science landlords has another $1.7 billion to spend on acquisitions.

IQHQ Inc. this month completed a $1.7 billion equity raise, following up on a $770 million fund raise last winter that cleared the way for its acquisition of properties in Boston, Cambridge and Andover.

The company, which has offices in San Diego and Boston, completed the latest funding from a mix of new and existing investors, IQHQ said in an announcement. IQHQ now has a 4.4 million-square-foot pipeline of life science development projects in Boston, San Francisco and San Diego.

Raymond James advised the company on the latest fundraising round.

“During a turbulent year, IQHQ’s focus on the commercial life science sector has been a winning strategy as the market shows no signs of slowing down,” Jamie Graff, co-head of real estate at Raymond James, said in a statement.

IQHQ has assembled a 27-acre development site in Alewife including the GCP Applied Technologies campus and is partnering with Meredith Management on an office-lab project built on Massachusetts Turnpike air rights parcels in the Fenway. It’s also repositioning the 201,500-square-foot 4 Corporate Drive property in Andover and acquired 109 Brookline Ave., a 285,000-square-foot office building in Boston, in February for $270 million.
