("Wintrust") (NASDAQ: WTFC) announced today the pricing of a public offering of 1,200,000 shares of its common stock at $59.50 per share. All of the shares to be sold in the offering are being offered by an affiliate of RBC Capital Markets Corporation (the "forward purchaser") in connection with a forward sale agreement as discussed below. The forward purchaser also has granted an option to the underwriters of the offering to purchase up to an additional 180,000 shares to cover over-allotments, if any. The offering is being made under Wintrust's current shelf registration statement filed with the Securities and Exchange Commission. In connection with the offering, Wintrust entered into a forward sale agreement with the forward purchaser, under which the forward purchaser agreed to borrow and sell 1,200,000 shares of Wintrust common stock. The forward sale agreement will settle in 12 months, or earlier at Wintrust's option. Wintrust has the option to physically settle the forward sale agreement by delivering shares of common stock and receiving the net proceeds of the offering. If Wintrust elected to physically settle all of the 1,200,000 shares subject to the forward sale agreement, it would receive net proceeds of approximately $67.1 million, after deducting the underwriting discount. Wintrust also has the option to net stock settle or net cash settle the forward sale agreement. Wintrust intends to use the net proceeds that it receives upon settlement of the forward sale agreement to fund a portion of the purchase price for the company's previously announced acquisitions of Antioch Holding Company and First Northwest Bancorp, Inc. and for general corporate purposes.
