First Interstate BancSystem, Inc. (“First Interstate”) (NASDAQ:FIBK), a financial and bank holding company headquartered in Billings, Montana, announced today that its board of directors has authorized a stock repurchase program for the repurchase of up to 2,000,000 shares, or approximately 10%, of the Company’s outstanding Class A common stock, over the next 12 months. “Our strong balance sheet and consistent capital generation has put us in the position to initiate a stock repurchase program,” said Ed Garding, President and Chief Executive Officer of First Interstate BancSystem, Inc. “Our Board of Directors believes that repurchasing our stock represents an attractive investment opportunity for the Company, while also providing us with a valuable lever for managing our capital ratios so we can enhance the level of returns we generate for our shareholders.” The program will be conducted in a manner intended to comply with the safe harbor provisions of Rule 10b-18 promulgated under the Securities Exchange Act of 1934, as amended, and to minimize the impact of the purchases upon the market for the securities. The repurchase program is subject to the insider-trading window periods imposed by our Company’s trading policy, and may be suspended or terminated at any time by our board of directors without prior notice. Under the program, we may, but are not required to, purchase shares of our Class A common stock from time to time through open market or privately negotiated transactions, as market and business conditions permit. Any repurchased shares will be returned to authorized but unissued shares of our Class A common stock in accordance with Montana law.
