Wolverine Bancorp, Inc. Adopts Stock Repurchase Program

Midland, Michigan, February 14, 2012. Wolverine Bancorp, Inc. (the “Company”) (Nasdaq: WBKC), the holding company for Wolverine Bank, announced today that its Board of Directors has authorized a stock repurchase program pursuant to which the Company intends to repurchase up to 5% of its issued and outstanding shares, or up to approximately 125,375 shares. The repurchase program permits shares to be repurchased in open market or private transactions, through block trades, and pursuant to any trading plan that may be adopted in accordance with Rule 10b5-1 of the Securities and Exchange Commission.

Repurchases will be made at management’s discretion at prices management considers to be attractive and in the best interests of both the Company and its stockholders, subject to the availability of stock, general market conditions, the trading price of the stock, alternative uses for capital, and the Company’s financial performance. Open market purchases will be conducted in accordance with the limitations set forth in Rule 10b-18 of the Securities and Exchange Commission and other applicable legal requirements.

The repurchase program may be suspended, terminated or modified at any time for any reason, including market conditions, the cost of repurchasing shares, the availability of alternative investment opportunities, liquidity, and other factors deemed appropriate. These factors may also affect the timing and amount of share repurchases. The repurchase program does not obligate the Company to purchase any particular number of shares, and there is no guarantee as to the exact number of shares to be repurchased by the Company.
