Platteville, WI, August 2, 2012— Wisconsin Bank & Trust a Madison-based subsidiary of Heartland Financial USA, Inc. (NASDAQ: HTLF), announced today that Heartland has entered into a definitive merger agreement with First Shares, Inc. (FSI), parent company of First National Bank in Platteville, Wisconsin. According to terms of the agreement, Heartland will acquire FSI in a transaction valued at approximately $11 million and estimated at 60 percent stock and 40 percent cash.

Under terms of the agreement, which has been unanimously approved by the boards of directors of both companies, the outstanding shares of FSI will be converted into a combination of cash and shares of Heartland common stock with the aggregate purchase price to be based upon the financial position of FSI prior to closing. Simultaneous with closing of the transaction, First National Bank will be merged into Heartland’s Wisconsin Bank & Trust subsidiary. The transaction is expected to be a tax-free exchange with respect to the stock consideration received by the shareholders of FSI.

“We are expanding our footprint in southwestern Wisconsin and joining forces with a bank that shares a strong culture of respect for the customer and commitment to the community,” said Tom Wilkinson, chairman and CEO of Wisconsin Bank & Trust. “First National Bank is an excellent fit for our community banking business model, and its locations match our desire to ‘fill-in’ Wisconsin Bank & Trust’s presence in or close to our existing geographies in Monroe and Madison.”

Kevin Tenpas, president of the bank added, “Wisconsin Bank & Trust is the new name for Wisconsin Community Bank in Madison and Monroe and Heartland Business Bank in the Green Bay and Sheboygan markets. The Wisconsin-chartered bank had been operating under two distinct names for 15 years. The new name unites both entities to serve clients under a common brand, fostering opportunities to expand the bank’s presence in the state. First National Bank is the first bank to be acquired under the new name.”

“We are attracted to Platteville as an education center with the University of Wisconsin – Platteville and as a medical center with Southwest Health Center headquartered there,” continued Wilkinson. “Both are major employers and vital economic engines. Additionally, Platteville serves a robust agricultural market in southwest Wisconsin,” said Wilkinson.

First National Bank has assets of approximately $130 million, loans of $88 million and deposits of $114 million as of June 30, 2012. Incorporated in 1891, the bank is one of the first national banks organized in Wisconsin. In addition to its main office in Platteville, the bank operates branch offices in Lancaster and Hazel Green, Wisconsin.

The transaction is subject to approvals by FSI shareholders and bank regulatory authorities, and is expected to close during the fourth quarter of 2012.

“Our board views this merger as an excellent move for the customers of First National Bank,” said Dale Kretschmar, First National’s president and CEO. “As we considered our strategic direction, including the importance of identifying a potential quality merger partner, Heartland stood out as an excellent fit. We are very pleased to partner with a strong community banking company that is committed to face-to-face customer service and locally-based banking that will continue our long tradition of strong community support.

“We believe our customers will benefit from this merger. They will have access to a wide selection of convenient financial products and services offered by Wisconsin Bank & Trust,” said Kretschmar

Kretschmar continued, “Since its founding in 1891, First National has proudly served the people of southwestern Wisconsin with personal service and community leadership. Wisconsin Bank & Trust is built on the same principles. We are certain that our customers and communities will see many similarities once the merger is completed. At the same time, they will have access to a wider menu of financial services and enhanced technology.”

Tenpas concluded, “We will be acquiring a talented team of local management and staff with an excellent knowledge of the community and the customers they serve. The First National Bank locations represent solid and steady markets.”
