FOR IMMEDIATE RELEASE

County Bancorp, Inc. announces definitive agreement for merger with

Fox River Valley Bancorp, Inc.

MANITOWOC, WI., Nov. 20, 2015 – County Bancorp, Inc. (Nasdaq: ICBK) (“County”) and Fox River Valley Bancorp, Inc. (“Fox River Valley”) announced today that they have entered into a definitive agreement to merge Fox River Valley into County. Upon completion of the transaction, Fox River Valley’s subsidiary bank, The Business Bank (“TBB”) will be merged into County’s subsidiary bank, Investors Community Bank (“ICB”).

Subject to possible adjustment, the aggregate purchase price will be approximately $28.9 million. In the merger, shares of Fox River Valley common stock outstanding will be converted into the right to receive merger consideration paid in a combination of cash and stock, subject to an election process. In aggregate, the consideration in the transaction will constitute 50% cash and 50% shares of County common stock.

Upon closing, the combined institution will have more than $1 billion in assets, and County will be the sixth largest exchange traded bank holding company headquartered in the State of Wisconsin. The merger will add to ICB’s business banking platform and expand its reach into contiguous markets with the addition of TBB’s Appleton and Green Bay branches to complement ICB’s two current branch offices in Manitowoc and Stevens Point and three loan production offices. As of September 30, 2015, Fox River Valley had approximately $255 million in assets, $152 million in loans and $220 million in deposits; and County had approximately $845 million in assets, $704 million in loans and $636 million in deposits.

Timothy J. Schneider, President of County and CEO of ICB, stated, “This merger with Fox River Valley represents a strategic opportunity for us to achieve our previously-stated objective of expanding our commercial lending and business banking platform. Fox River Valley has built a solid business banking franchise in two distinct markets that are logical geographical fits and areas we have been targeting for expansion.”

“The combination of our organizations also diversifies the mix of our loan portfolio, creating the opportunity to continue to grow both commercial and agricultural lending in the future. We see this transaction as a perfect opportunity to optimally utilize the capital we recently raised, and position us for growth in the short and long-term.”

Schneider continued, “We expect the transaction to be 8-10% accretive to County’s earnings per share during the 12 months following completion of the transaction, with a tangible book value earn back period of approximately three and a half years. Following completion of the merger, County’s pro forma capital ratios will continue to significantly exceed regulatory well-capitalized levels, enabling us to continue to take advantage of future growth opportunities throughout our market area in both our business and agricultural banking markets.” As part of the transaction, County will add two additional members to its board from the Fox River Valley board, and William Censky will remain as County board chair.

Bill Hodgkiss, President & CEO of Fox River Valley, stated, “We believe County is an ideal partner for our bank, and we are excited to become a part of the organization. Like Fox River Valley, County is deeply committed to its communities, and through this combination of our two organizations, we will be in a position to better serve our customers. County’s reputation, financial strength and capabilities will enhance our ability to meet the expanding needs of our customers. Furthermore, our shareholders will be receiving shares of a strong, successful banking company that is listed on NASDAQ, providing a more liquid market for those shares.”

The transaction is expected to be completed in the first half of 2016. Completion of the transaction is subject to approval by regulatory authorities and Fox River Valley’s shareholders, as well as certain other customary closing conditions.
