First Interstate BancSystem, Inc. Files Shelf Registration Statement on Form S-3

Company Release - 9/22/2017 5:15 PM ET

BILLINGS, Mont.--(BUSINESS WIRE)-- First Interstate BancSystem, Inc. (NASDAQ: FIBK) announced today that it has filed a shelf registration statement on Form S-3 with the United States Securities and Exchange Commission, or SEC. The registration statement is intended to provide the company with flexibility to access the capital markets from time to time, when deemed appropriate or necessary, and in a timely manner. Under the shelf registration statement, once declared effective by the SEC, First Interstate may from time to time issue additional shares of its Class A Common Stock up to an aggregate amount of $250 million.

The company has no plans at this time to issue any shares under the registration statement. First Interstate President and CEO, Kevin Riley, said, “As we continue to execute on our intended growth strategy and identify potential opportunities for expansion, we recognize that access to additional capital and the ability to provide opportunities for institutional investors to access First Interstate capital stock could be beneficial, and we have filed this shelf registration statement to give us that optionality.”

The shelf registration statement has been filed with the SEC but has not yet become effective. These securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. This press release shall not constitute an offer to sell or a solicitation of an offer to buy, nor shall there be any sale of any shares covered by the shelf registration statement in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration and qualification under the securities laws of such jurisdiction. Any offering of the shares covered by the shelf registration statement will be made solely by means of a prospectus and an accompanying prospectus supplement relating to that offering. A copy of the prospectus included in the shelf registration statement may be obtained on the SEC’s website at www.sec.gov.

After the shelf registration statement becomes effective, First Interstate may offer and sell shares of Class A Common Stock covered by the registration statement through one or more methods of distribution, subject to market conditions and First Interstate’s capital needs. The terms of any offering under the shelf registration statement will be established at the time of the offering and described in a prospectus supplement filed with the SEC prior to the completion of the offering.
