<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">This Current Report on Form 8-K is being filed in connection with the
completion on February 1, 2022 (the &#8220;Closing Date&#8221;) of the previously announced merger between First Interstate BancSystem,
Inc., a Montana corporation (&#8220;First Interstate&#8221; or the &#8220;Company&#8221;), and Great Western Bancorp, Inc., a Delaware
corporation (&#8220;Great Western&#8221;) pursuant to the Agreement and Plan of Merger, dated as of September 15, 2021 (the &#8220;Merger
Agreement&#8221;), by and between First Interstate and Great Western.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Pursuant to the Merger Agreement, Great Western merged with and into
First Interstate, with First Interstate continuing as the surviving corporation (the &#8220;Merger&#8221;). Immediately following the
Merger, Great Western&#8217;s wholly owned banking subsidiary, Great Western Bank, merged with and into First Interstate&#8217;s wholly
owned banking subsidiary, First Interstate Bank (the &#8220;Bank Merger&#8221;), with First Interstate Bank continuing as the surviving
bank in the Bank Merger.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Pursuant to the Merger Agreement, at the effective time of the Merger

Stock&#8221;) issued and outstanding immediately prior to the Effective Time, other than certain shares held by First Interstate and Great
Western, was converted into the right to receive 0.8425 shares (the &#8220;Exchange Ratio&#8221;, and such shares, the &#8220;Merger Consideration&#8221;)
of Class A common stock, no par value, of First Interstate (&#8220;First Interstate Class A Common Stock&#8221;). Each holder of Great
Western Common Stock converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of First
Interstate Class A Common Stock (after taking into account all shares held by such holder) will instead receive cash (without interest)
in lieu of such fractional share in accordance with the terms of the Merger Agreement.</p>

Great Western restricted stock unit award in respect of shares of Great Western Common Stock (a &#8220;Great Western RSU&#8221;) was,
by virtue of the Merger, fully vested and was cancelled and converted automatically into the right to receive the Merger Consideration,
as if such Great Western RSU had been settled in shares of Great Western Common Stock immediately prior to the Effective Time. Each outstanding
performance stock unit award in respect of shares of Great Western Common Stock (a &#8220;Great Western PSU&#8221;), by virtue of the
Merger, vested at the greater of the target and actual levels of performance, as determined by the Compensation Committee of the Great
Western board of directors prior to the Effective Time, and was cancelled and converted automatically into the right to receive the Merger
Consideration, as if such Great Western PSU had been settled in shares of Great Western Common Stock immediately prior to the Effective
Time.</p>

47 million shares of First Interstate Class A Common Stock. The issuance of shares of First Interstate Class A Common Stock in connection
