COLUMBUS, Ohio – March 4, 2014 – Huntington Bancshares Incorporated (NASDAQ: HBAN) announced today that it has completed its merger of Camco Financial Corp., parent company of Advantage Bank, based in Cambridge, Ohio.

The simultaneous closing and conversion were completed successfully with the Advantage banking offices having opened March 3, 2014, as Huntington branches.

“We are extremely pleased to welcome the more than 55,000 customers of Advantage Bank to Huntington,” said Stephen D. Steinour, chairman, president and CEO of Huntington Bank. “With the addition of nine new branches, former Advantage customers and long-time Huntington customers will enjoy more convenience and accessibility from Cambridge to Cincinnati. We are grateful to our customers for their ongoing commitment to Huntington and we look forward to continue to invest in products and services that will make banking easier for them.”

Advantage small business owners can also begin working with Huntington’s business bankers, who have helped the bank become the third largest SBA lender in the country as of the most recent fiscal year.

Shareholders accounting for approximately 88 percent of Camco shares outstanding elected to receive Huntington common stock in the transaction. Because the merger agreement provides that 80 percent of the outstanding Camco shares will be converted into Huntington common stock (1) shareholders who validly elected the stock consideration will receive a portion of the merger consideration in the form of Huntington stock, with the remainder in cash, (2) shareholders who validly elected the cash consideration will receive all cash in the merger, and (3) all shareholders who failed to make a valid election will receive cash in the merger.

Beginning Monday, March 10, Camco shareholders can call Computershare’s Corporate Actions at 855-396-2084 and reference “Huntington” for additional information.
