People’s United is planning to close 15 branches, most of which were recently acquired from Farmington Bank.

The Hartford Courant reported the news and confirmed with the bank earlier this week.

The branches will close between Jan. 24 and Jan. 26 and extend from Vernon west to Southington and south to Rocky Hill and Wethersfield. All but two are former Farmington branches.

The news is not exactly unexpected, as People’s United had warned that due to the similar markets it was in with Farmington, branch closings were inevitable. The bank had also touted potential cost savings as a significant driver behind its interest in Farmington Bank.

People’s United closed on its acquisition of Farmington Bank in early October, in an all stock transaction valued at roughly $544 million and 180 percent tangible book value.

Jack Barnes, CEO of People’s United, said on a conference call following the acquisition that 71 percent of Farmington Bank’s branches were within 2 miles of People’s United Bank branches, and that 100 percent of Farmington branches were within 5 miles of a People’s United Bank branch.

He also said he expected the company to retain many Farmington employees, although that may have been premature, as Farmington Bank laid off more than a quarter of its workforce in September.
