NORWICH, N.Y. and SYRACUSE, N.Y., March 7, 2013 (GLOBE NEWSWIRE) -- NBT Bancorp Inc. (NBT) (Nasdaq:NBTB) and Alliance Financial Corporation (Alliance) (Nasdaq:ALNC) announced today that both companies received approval from stockholders at special meetings conducted this week to complete their merger. Pursuant to the Agreement and Plan of Merger by and between NBT and Alliance, dated October 7, 2012, Alliance will merge with and into NBT. Additionally, Alliance Bank, N.A., a wholly-owned subsidiary of Alliance, will merge with and into NBT's wholly-owned subsidiary, NBT Bank, N.A. The merger of Alliance into NBT is expected to be completed at the close of business on March 8, 2013, and will provide NBT with the addition of $1.4 billion in assets, including $920 million in net loans held for investment, and $1.1 billion in deposits. Following a weekend systems conversion, Alliance Bank branches will open as NBT Bank offices on March 11, 2013. NBT and Alliance have worked together to minimize the impact of this transition to customers, who will retain their account numbers following the conversion and be able to use their current checks and debit cards. Direct deposits will also continue without interruption. Alliance Bank's 26 branches are located in a five-county area in central New York—including the counties of Onondaga, Cortland, Madison, Oneida and Oswego—that is contiguous to NBT Bank's existing footprint in upstate New York. With the merger, NBT Bank's branch network will grow to a total of 161 locations in five states, including New York, Pennsylvania, Vermont, Massachusetts and New Hampshire. "We are excited to bring together our two community-minded upstate New York banks," said NBT President and CEO Martin Dietrich. "We share a commitment to our customers and to banking fundamentals that will create an even stronger local banking resource to benefit the markets we serve and create long-term value for our stockholders."
