Talmer Bancorp, Inc. Announces Closing of Secondary Common Stock Offering and Share Repurchase

TROY, Mich., August 31, 2015 /PRNewswire/ — Talmer Bancorp, Inc. (“Talmer”) (Nasdaq: TLMR) announced today the closing of the previously announced secondary offering by which funds affiliated with WL Ross & Co. LLC (the “WL Ross Funds”) agreed to sell 9,664,579 shares of their Talmer Class A common stock in an underwritten public offering.  The WL Ross Funds received all of the net proceeds from the offering.

Talmer repurchased 5,077,000 shares in the offering.  The shares were repurchased at a price of $14.77 per share, for an aggregate purchase price of $74,987,290.

Keefe, Bruyette & Woods, Inc., A Stifel Company, acted as the sole underwriter for the offering and reoffered 4,587,579 shares to the public at $14.95 per share.

The WL Ross Funds fully divested their ownership in Talmer’s common stock in the offering and Denny Kim, the director representative for the WL Ross Funds, resigned from the board of directors of Talmer and Talmer Bank and Trust effective August 31, 2015.

“We believe we are well positioned to continue to capitalize upon growth opportunities in our markets,” said David Provost, Talmer President and Chief Executive Officer. “We believe completion of the share repurchase will allow us to improve balance sheet efficiency and better leverage our strong capital position in the near term.  We are continuing to make progress on reducing the complexity of our business and driving operating leverage through the combination of quality loan and deposit growth and the realization of synergies from previously completed acquisitions.  Our focus and efforts remain solidly on enhancing franchise value through the execution of prudent growth opportunities in order to drive strong returns for our shareholders.”

Provost continued, “We would also like to take this opportunity to thank WL Ross & Co. for stepping up during a very turbulent time and providing the capital resources to help us save banks and maintain credit availability in our communities. With that support, we were able to grow from under $100 million in total assets in 2010 to more than $6.4 billion at June 30th of this year through a combination of acquisitions and strong organic growth.  In the majority of those acquisitions, Talmer was the sole bidder on banks that had been serving their communities for generations.  Through this process, we believe we have saved hundreds of jobs, helped to reignite communities and always worked hard to be good corporate citizens.  WL Ross & Co. has been a great partner and shareholder in that effort, and their counsel has been invaluable to us as we executed on our plan. We sincerely thank Wilbur Ross for his previous service on our Board and his dedication and confidence in Talmer. We also thank Denny Kim for his contribution and commitment as a board member as well.”

Wilbur L. Ross Jr. added, “We are proud to have recognized that Talmer would quickly create a major regional bank in the Midwest. David Provost, Gary Torgow and their team have executed their business plan flawlessly and we have become close personal friends. We are proud to have been their partners and look forward to their future success. Our sale is due to portfolio considerations.”
