The properties include 225, 266, and 275 Second Ave. in Waltham, as well as 780 and 790 Memorial Drive in Cambridgeport, reported by Boston Business Journal.  

The Waltham properties were purchased for $266 million, while the two Cambridge sites were acquired for $99 million. The combined space of the five buildings amounts to approximately 425,000 square feet.
