Pfizer, whose employees were supposed to be the clientele of the Fort Trumbull redevelopment project, completed its merger with Wyeth, resulting in a consolidation of research facilities of the two companies. Pfizer chose to retain the Groton campus on the east side of the Thames River, closing its New London facility in late 2010 with a loss of over 1,000 jobs. That coincided with the expiration of tax breaks on the New London site that would have increased Pfizer's property tax bill by almost 400 percent.
