Riley, President and Chief Executive Officer of First Interstate BancSystem, Inc. “We are executing well on our strategic priorities in the current environment, which enabled us to generate positive trends in a number of key areas including an increase in our total deposits, more stability in our net interest margin, lower expenses, improved asset quality, and an increase in regulatory capital ratios.

“While we will remain conservative in our new loan production, we continue to believe that this is a favorable environment to add new commercial and retail customers throughout our markets given the financial strength, breadth of products and services, and superior level of service that we offer. We believe our continued success in adding new relationships will enhance our ability to generate long-term profitable growth and create additional value for our shareholders in the years to come,” said Mr. Riley.

DIVIDEND DECLARATION

On October 24, 2023, the Company’s board of directors declared a dividend of $0.47 per common share, payable on November 16, 2023, to common stockholders of record as of November 6, 2023. The dividend equates to a 7.2% annualized yield based on the $26.10 per share average closing price of the Company’s common stock as reported on NASDAQ during the third quarter of 2023.

NET INTEREST INCOME

Net interest income decreased $4.7 million, or 2.2%, to $213.7 million, during the third quarter of 2023, compared to net interest income of $218.4 million during the second quarter of 2023 and decreased $53.1 million, or 19.9%, during the third quarter of 2023 from the third quarter of 2022, primarily due to an increase in interest expense as a result of a higher levels and costs of interest-bearing liabilities.

• Interest accretion attributable to the fair valuation of acquired loans from acquisitions contributed to net interest income during the third quarter of 2023, the second quarter of 2023, and the third quarter of 2022, in the amounts of $5.2 million, $4.6 million, and $17.7 million, respectively.

The net interest margin ratio, on an FTE basis, was 3.07% for the third quarter of 2023, compared to 3.12% during the second quarter of 2023, and 3.71% during the third quarter of 2022. Excluding interest accretion from the fair value of acquired loans, on a quarter-over-quarter basis, the net interest margin ratio was 3.00%, a decrease of 5 basis points from the prior quarter, primarily driven by higher interest-bearing deposit costs, which was partially offset by loan yield expansion. Excluding interest accretion from the fair value of acquired loans, on a year-over-year basis, the net interest margin ratio decreased 47 basis points, primarily as a result of higher short-term borrowing costs, and higher interest-bearing deposit costs, which was partially offset by loan yield expansion and a modestly favorable change in the mix of earning assets.

(REDUCTION OF) PROVISION FOR CREDIT LOSSES

During the third quarter of 2023, the Company recorded a reduction of credit losses of $0.1 million, which included a provision for credit losses of $3.2 million on loans held for investment, reduction of credit losses for unfunded commitments of $2.0 million, and reduction of credit losses for investment securities of $1.3 million. This compares to a provision for credit losses of $11.7 million during the second quarter of 2023 and a provision for credit losses of $8.4 million during the third quarter of 2022.

For the third quarter of 2023, the allowance for credit losses included net charge-offs of $1.1 million, or an annualized 0.02% of average loans outstanding, compared to net charge-offs of $11.4 million, or an annualized 0.25% of average loans outstanding, for the second quarter of 2023, and net charge-offs of $12.0 million, or an annualized 0.27% of average loans outstanding, for the third quarter of 2022. Net loan charge-offs in the third quarter of 2023 were composed of charge-offs of $6.2 million and recoveries of $5.1 million.

The Company’s allowance for credit losses as a percentage of period-end loans held for investment increased to 1.24% at September 30, 2023 from 1.23% at June 30, 2023, and from 1.21% at September 30, 2022.

NON-INTEREST INCOME

Non-interest income was $42.0 million for the third quarter of 2023, decreasing $2.1 million compared to the second quarter of 2023. Compared to the third quarter of 2022, non-interest income increased $19.1 million. The increase was primarily due to the realized loss of $24.2 million on the disposition of available-for-sale investment securities during the third quarter of 2022 when there were no such losses realized in the third quarter of 2023.

NON-INTEREST EXPENSE

The Company’s non-interest expense was $161.1 million for the third quarter of 2023, a decrease of $2.8 million from the second quarter of 2023.

Compared to the third quarter of 2022, non-interest expense decreased by $12.1 million. The decrease is partially due to the acquisition expenses incurred during the third quarter of 2022 related to the acquisition of GWB and partially due to lower severance and incentive accruals included within salaries and wages and lower advertising and donation expenses included within other expenses during the third quarter of 2023.

BALANCE SHEET

Total assets decreased $435.5 million, or 1.4%, to $30,540.8 million as of September 30, 2023, from $30,976.3 million as of June 30, 2023, primarily due to a decrease in investment securities and cash and cash equivalents which were used to paydown other borrowed funds. Total assets decreased $803.9 million, or 2.6%, from $31,344.7 million as of September 30, 2022, primarily due to a decrease in investment securities, partially offset by increases in loans held for investment.

Investment securities decreased $1,381.9 million, or 13.5%, from $10,269.1 million as of September 30, 2022, which was primarily the result of the disposition of $853.0 million of investment securities during the first quarter of 2023, normal cash flow activity, and declines in fair market values during the period.

NON-GAAP FINANCIAL MEASURES

In addition to results presented in accordance with accounting principles generally accepted in the United States of America, or GAAP, this press release contains the following non-GAAP financial measures that management uses to evaluate our performance relative to our capital adequacy standards: (i) tangible common stockholders’ equity; (ii) tangible assets; (iii) tangible book value per common share; (iv) tangible common stockholders’ equity to tangible assets; (v) average tangible common stockholders’ equity; (vi) return on average tangible common stockholders’ equity; and (vii) adjusted net interest margin ratio (FTE). Tangible common stockholders’ equity is calculated as total common stockholders’ equity less goodwill and other intangible assets (excluding mortgage servicing rights). Tangible assets are calculated as total assets less goodwill and other intangible assets (excluding mortgage servicing rights). Tangible book value per common share is calculated as tangible common stockholders’ equity divided by common shares outstanding. Tangible common stockholders’ equity to tangible assets is calculated as tangible common stockholders’ equity divided by tangible assets. Average tangible common stockholders’ equity is calculated as average stockholders’ equity less average goodwill and other intangible assets (excluding mortgage servicing rights). Return on average tangible common stockholders’ equity is calculated as net income available to common shareholders divided by average tangible common stockholders’ equity. Adjusted net interest margin ratio (FTE) is calculated as adjusted net FTE interest income divided by adjusted average interest earning assets. These non-GAAP financial measures may not be comparable to similarly titled measures reported by other companies because other companies may not calculate these non-GAAP measures in the same manner. They also should not be considered in isolation or as a substitute for measures prepared in accordance with GAAP.

The Company adjusts the most directly comparable capital adequacy GAAP financial measures to the non-GAAP financial measures described in subclauses (i) through (vi) above to exclude goodwill and other intangible assets (except mortgage servicing rights). To derive the non-GAAP financial measure identified in subclause (vii) above, the Company adjusts its net interest income to include its FTE interest income and exclude purchase accounting interest accretion on acquired loans. Management believes these non-GAAP financial measures, which are intended to complement the capital ratios defined by banking regulators and to present on a consistent basis our and our acquired companies’ organic continuing operations without regard to acquisition costs and other adjustments that we consider to be unpredictable and dependent on a significant number of factors that are outside our control, are useful to investors in evaluating the Company’s performance because, as a general matter, they either do not represent an actual cash expense and are inconsistent in amount and frequency depending upon the timing and size of our acquisitions (including the size, complexity and/or volume of past acquisitions, which may drive the magnitude of acquisition related costs, but may not be indicative of the size, complexity and/or volume of future acquisitions or related costs), or they cannot be anticipated or estimated in a particular period (in particular as it relates to unexpected recovery amounts). This impacts the ratios that are important to analysts and allows investors to compare certain aspects of the Company’s capitalization to other companies.

See the Non-GAAP Financial Measures table included herein and the textual discussion for a reconciliation of the above described non-GAAP financial measures to their most directly comparable GAAP financial measures.
