Sterling Financial Corporation (NASDAQ:STSA) (the “Company”) today announced the completion of its acquisition of American Heritage Holdings, the holding company for Borrego Springs Bank, NA, for total cash consideration of $6.5 million. Immediately following completion of the acquisition, Borrego Springs Bank, NA, was merged with and into the Company’s principal operating subsidiary, Sterling Savings Bank (“Sterling”). “This transaction expands Borrego Springs Bank’s government guaranteed lending arena,” said David DePillo, vice chairman and chief lending officer of Sterling. “This type of lending is a key component of our balanced business banking delivery platform.” Sterling expects that the Borrego Springs Bank Florida loan production office operations, which specialize in SBA Credit Xpress loans, will cease operations by the end of the first quarter of 2013.
