Overview
NewAlliance Bank was a regional savings-bank franchise serving Connecticut and western Massachusetts. The operating brand was associated with NewAlliance Bancshares, Inc., a holding company formed in 2003, and emerged in 2004 from the combination of New Haven Savings Bank, The Savings Bank of Manchester, and Tolland Bank. Its institutional roots were considerably older than the NewAlliance name: New Haven Savings Bank had been chartered in 1838, giving the combined organization a long history in Connecticut community banking. The bank expanded through a series of acquisitions after its formation. In July 2005, it acquired Trust Company of Connecticut, adding investment-management, trust, and estate-planning capabilities. In January 2006, it acquired Cornerstone Bank and its parent, Cornerstone Bancorp, Inc. In January 2007, Westbank, based in West Springfield, Massachusetts, became part of the company. These transactions broadened NewAlliance's branch, deposit, lending, and wealth-management presence beyond its original Connecticut foundations and into western Massachusetts. NewAlliance operated as a full-service regional bank. Its activities included deposit accounts, consumer and commercial lending, branch and ATM services, and related financial services. Through Trust Company of Connecticut, which operated as a division of the bank, it provided investment management and trust and estate-planning services. NewAlliance Investments, Inc., a wholly owned subsidiary, offered investment and insurance products to individuals and businesses and was identified as a member of FINRA and SIPC. The holding company became publicly traded on the New York Stock Exchange in 2004 under the symbol NAL. At December 31, 2009, the organization reported approximately $5.0 billion in deposits, $8.4 billion in assets, 87 branches, and more than 100 ATMs. The company described itself as one of the larger New England-based banking organizations and as a major Connecticut-based savings bank. In August 2010, First Niagara Bank announced an agreement to acquire NewAlliance. The transaction received final approval and was completed through a merger in April 2011, ending NewAlliance Bank's independent existence as a banking organization. First Niagara itself was later acquired by KeyBank in 2016. Accordingly, NewAlliance is best understood today as a former regional banking brand whose franchise and operations were absorbed into successor institutions.
History
NewAlliance Bank was created during a period of consolidation among Connecticut savings institutions. Its immediate corporate structure took shape in 2003, when NewAlliance Bancshares, Inc. was formed. The NewAlliance banking operation began in 2004 through the combination of three established institutions: New Haven Savings Bank, The Savings Bank of Manchester, and Tolland Bank. Although the NewAlliance name was new, one of its principal predecessors, New Haven Savings Bank, traced its charter to 1838. The combination created a sizable Connecticut-based savings-bank organization with a broader branch network and a larger balance sheet than any of the constituent institutions could have maintained independently. NewAlliance Bancshares became publicly traded on the New York Stock Exchange in 2004 under the ticker NAL. The bank's business model centered on community and regional banking, including deposits, lending, branch banking, and services for consumers and businesses. NewAlliance pursued expansion through acquisitions. In July 2005, the company acquired Trust Company of Connecticut. The trust company became a division of NewAlliance Bank and contributed investment-management, fiduciary, and trust and estate-planning capabilities. The acquisition also substantially increased the assets managed through the bank's trust operations. In January 2006, NewAlliance acquired Cornerstone Bank and Cornerstone Bancorp, Inc., adding another banking franchise to the organization. In January 2007, Westbank, operated by Park West Bank & Trust Co. and based in West Springfield, Massachusetts, became part of NewAlliance. This transaction extended the company's reach into western Massachusetts. The organization also maintained a securities and insurance-related business through NewAlliance Investments, Inc. The wholly owned subsidiary offered investment and insurance products to individual and business customers and was associated with FINRA and SIPC membership. Together with Trust Company of Connecticut, this broadened NewAlliance's offering beyond traditional deposit-taking and lending. By the end of 2009, NewAlliance reported approximately $5.0 billion in deposits and $8.4 billion in assets. Its distribution network consisted of 87 branches and more than 100 ATMs, with operations concentrated in Connecticut and western Massachusetts. The company characterized itself as one of the larger banking organizations based in New England and among the leading Connecticut-based savings banks. NewAlliance's independent history ended through a merger rather than a bankruptcy or regulatory closure. First Niagara Bank announced its acquisition of NewAlliance in August 2010. Following regulatory approval, the merger was completed in April 2011, and NewAlliance was incorporated into First Niagara Bank. First Niagara later became part of KeyBank through KeyBank's 2016 acquisition of First Niagara. The NewAlliance name therefore survives primarily as a historical banking brand and as part of the corporate lineage of institutions that succeeded it.
