“The third quarter was a great quarter for First Interstate, as the combined company is beginning to hit its stride. An acceleration in loan growth from across the footprint, and significant margin expansion led to a notable improvement in the Company’s operating performance. At the same time, we made meaningful progress on asset quality improvement and continued our pro-active capital management strategy by completing our share repurchase authorization. We are happy to announce today that the sustainable earnings power of the Company has given us the confidence needed to increase our quarterly cash dividend by 14.6%, to $0.47 per share, starting in the fourth quarter,” said Kevin P. Riley, President and Chief Executive Officer of First Interstate BancSystem, Inc.

“For as pleased as we are with the results, we expect to see further improvement in the fourth quarter, as the lending environment remains favorable and margin expansion should continue. Based on the strength of the franchise we have built, we believe we are well positioned to continue generating strong financial results for our shareholders, while continuing to operate with a conservative approach to risk management to effectively manage through varied economic conditions,” said Mr. Riley.

DIVIDEND DECLARATION

On October 24, 2022, the Company’s board of directors declared a dividend of $0.47 per common share, payable on November 18, 2022, to common stockholders of record as of November 8, 2022. The dividend equates to a 4.7% annualized yield based on the $40.28 per share average closing price of the Company’s common stock as reported on NASDAQ during the third quarter of 2022.

RECENT ACQUISITION

On February 1, 2022, the Company completed its acquisition of Great Western and GWB, a Sioux Falls, South Dakota based community bank with 174 banking offices across Arizona, Colorado, Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, and South Dakota. Consideration for the acquisition totaled approximately $1.7 billion consisting of the issuance of 46.9 million shares of the Company’s Class A common stock valued at $36.76 per share, the opening price of the Company’s Class A common stock as quoted on the NASDAQ stock market on the acquisition date. GWB was merged with our existing bank subsidiary, First Interstate Bank, contemporaneously with the closing of the parent company merger. The core system conversion was completed on May 23, 2022.

As of the acquisition date, Great Western had total assets with fair values of $13,353.3 million, loans held for investment with fair values of $7,705.0 million and deposits with fair values of $11,688.0 million. Adjustments to the fair value marks for premises and equipment, other assets, and accounts payable and accrued expenses were made since the prior quarter. The adjustments resulted in a net increase to goodwill of $0.2 million from the second quarter reported balances. The fair values of the assets and liabilities acquired from GWB are provisional and the Company will finalize the amounts during the one-year measurement period. As of September 30, 2022, the Company recorded provisional goodwill of $478.4 million, customer relationship intangible assets of $22.8 million, and core deposit intangible assets of $50.1 million.

NET INTEREST INCOME

Net interest income increased $27.8 million, or 11.6%, to $266.8 million, during the third quarter of 2022, compared to $239.0 million during the second quarter of 2022, resulting from growth in average earning assets and the increase in our net interest margin. Net interest income increased $139.7 million, or 109.9%, during the third quarter of 2022, from $127.1 million during the third quarter of 2021, primarily as a result of the impact of the GWB acquisition, which was partially offset by a decrease of $13.9 million in PPP loan income compared to the third quarter of 2021.

• Interest accretion attributable to the fair valuation of acquired loans from acquisitions contributed $17.7 million, $16.7 million, and $2.3 million to net interest income during the third quarter of 2022, the second quarter of 2022, and the third quarter of 2021, respectively.

The net interest margin ratio was 3.71% for the third quarter of 2022 compared to 3.25% reported during the second quarter of 2022 and 2.90% during the third quarter of 2021. Excluding interest accretion from the fair value of acquired loans and PPP income, on a quarter-over-quarter basis the net interest margin increased 46 basis points which was primarily the result of a shift in the mix of earning assets toward loans, and an increase in the yield on loans, investment securities and cash. On the same basis year-over-year, the increase in net interest margin was the result of increased yields on earning assets, due to a shift in the mix of earning assets toward investment securities and loans, and higher yields on loans, investment securities and cash.

PROVISION FOR (REDUCTION OF) CREDIT LOSSES

During the third quarter of 2022, the Company recorded a provision for credit losses of $8.4 million, which included an additional provision for unfunded commitments of $3.5 million, primarily attributable to loan growth, compared to a reduction of provision for credit losses of $1.7 million during the second quarter of 2022. The Company recorded no provision for credit losses during the third quarter of 2021.

The allowance for credit losses is updated quarterly based on the current loan portfolio, asset quality metrics, and the current economic outlook. For the third quarter of 2022, the allowance for credit losses was impacted by net charge-offs of $12.0 million, or an annualized 0.27% of average loans outstanding, compared to net charge-offs of $0.3 million, or an annualized 0.01% of average loans outstanding, for the second quarter of 2022, and net charge-offs of $0.6 million, or an annualized 0.02% of average loans outstanding, for the third quarter of 2021.

The Company’s allowance for credit losses as a percentage of period-end loans held for investment was 1.21%, 1.28%, and 1.40% at September 30, 2022, June 30, 2022, and September 30, 2021, respectively. The decrease in the percentage from June 30, 2022 was driven by the improvement in overall credit quality and net charge offs, partially offset by qualitative additions related to the macro environment and forecast. Coverage of non-performing loans increased to 247.7% at September 30, 2022, compared to 200.5% at June 30, 2022 and decreased from 384.9% at September 30, 2021. The year-over-year decrease is a result of higher levels of non-performing loans related to the GWB acquisition.

NON-INTEREST INCOME

Non-interest income during the third quarter of 2022 compared to the second quarter of 2022 decreased $27.0 million. The primary driver of the decrease was a loss of $46.3 million incurred on the sale of $500 million in U.S. treasury notes previously swapped. The remaining deferred swap termination gain of $22.1 million was recognized at the time of sale, for a total net loss on sale of $24.2 million in the third quarter of 2022. In addition, mortgage banking revenues decreased due to a decrease in home loan production volume. These decreases were partially offset by an increase in other service charges, commissions, and fees.

Compared to the third quarter of 2021, non-interest income decreased by $16.6 million. The decrease was primarily due to decreases in mortgage banking revenues, reflecting a decrease in home loan production volume, and the net investment security losses, partially offset by increases in payments services revenues and other service charges, commissions, and fees, primarily related to the GWB acquisition.

NON-INTEREST EXPENSE

The Company’s non-interest expense was $173.2 million for the third quarter of 2022, a decrease of $37.1 million from the second quarter of 2022. The decrease was driven by lower acquisition related and salaries expenses, which were partially offset by an increase in other expenses. While salary and benefits expenses were down quarter over quarter, efficiencies gained through the acquisition were partially offset by higher short-term incentive expenses as a result of our performance. Other expenses includes a $0.5 million accrual for a pending litigation settlement and a $1.0 million increase in the Company’s donation contribution, in addition to elevated levels of FDIC insurance, fraud losses, information technology, and advertising expenses.

Compared to the third quarter of 2021, non-interest expense increased by $67.3 million. The increase is largely due to the acquisition of GWB including employee-related costs and operations extending into a larger footprint. The increase was partially offset by a decrease in acquisition related expenses, as a result of the continued completion of the GWB acquisition.

BALANCE SHEET

Total assets decreased $717.1 million, or 2.2%, to $31,344.7 million as of September 30, 2022, from $32,061.8 million as of June 30, 2022, primarily due to a decrease in cash and cash equivalents and declines in fair market values of investment securities. Total assets increased $11,972.5 million, or 61.8%, from $19,372.2 million as of September 30, 2021, primarily due to $13,353.3 million of assets acquired in the acquisition of GWB.

Securities purchased under repurchase agreements decreased $202.2 million, or 100.0%, as of September 30, 2022, from $202.2 million as of June 30, 2022. The decrease was related to the disposition of the securities.

Investment securities decreased $602.0 million, or 5.5%, to $10,269.1 million as of September 30, 2022, from $10,871.1 million as of June 30, 2022, and increased $4,247.4 million, or 70.5%, from $6,021.7 million as of September 30, 2021. The decrease in the current quarter was caused by normal cash flow activity and declines in fair market values given the current market conditions. The increase year-over-year was primarily due to the redeployment of cash and cash equivalents into the securities portfolio and $2,699.0 million of securities acquired as a result of the GWB acquisition.

Loans held for sale decreased $33.8 million, or 26.5%, to $93.6 million as of September 30, 2022, from $127.4 million as of June 30, 2022, primarily due to resolutions of loans acquired from GWB, partially offset by the addition of a commercial construction loan transferred into loans held for sale from loans held for investment. Loans held for sale increased $51.1 million, or 120.2%, from $42.5 million as of September 30, 2021, primarily due to the loans acquired from GWB.

The following table presents the composition and comparison of loans held for investment:

Loans held for investment included PPP loans, net of deferred fees, which were $5.9 million, $11.8 million, and $280.5 million as of September 30, 2022, June 30, 2022, and September 30, 2021, respectively. Excluding the impact of PPP loans, loans held for investment as of September 30, 2022, increased from June 30, 2022, primarily due to an increase in loans in our real estate portfolio.

The loans held for investment to deposit ratio increased to 68.0%, as of September 30, 2022, compared to 63.9% as of June 30, 2022.

Other assets increased $114.5 million, or 21.4%, to $649.5 million as of September 30, 2022, from $535.0 million as of June 30, 2022, primarily due to an increase in accrued interest receivable of $15.8 million, deferred tax asset of $46.9 million, new market tax credit investments of $18.5 million, and derivative assets of $18.8 million. Other assets increased $436.6 million, or 205.1%, as of September 30, 2022, from $212.9 million as of September 30, 2021. Exclusive of other assets of $262.5 million acquired from GWB, other assets increased $174.1 million, primarily due to an increase of the deferred tax asset driven by other comprehensive losses, partially offset by a decline in derivative assets.

Total deposits decreased $979.0 million, or 3.6%, to $25,884.8 million as of September 30, 2022, from $26,863.8 million as of June 30, 2022, primarily due to the declines in non-interest bearing, interest-bearing demand and savings deposits, partially offset by increases in time deposits. Total deposits increased $9,877.5 million, or 61.7%, from $16,007.3 million as of September 30, 2021, primarily due to $11,688.0 million of deposits acquired in the acquisition of GWB, partially offset by a decrease in non-interest bearing, interest-bearing demand, and savings deposits.

Securities sold under repurchase agreements decreased $159.1 million, or 12.9%, to $1,075.6 million as of September 30, 2022, from $1,234.7 million as of June 30, 2022 and increased $68.1 million, or 6.8%, from $1,007.5 million as of September 30, 2021. Exclusive of $74.0 million in such securities acquired in the GWB acquisition, securities sold under repurchase agreements decreased $5.9 million, or 0.6% from September 30, 2021. Fluctuations in repurchase agreement balances correspond with fluctuations in the liquidity of the Company’s clients.

Other liabilities increased $62.1 million, or 15.2%, to $470.0 million as of September 30, 2022, from $407.9 million as of June 30, 2022, primarily due to an increase in derivative liabilities of $69.2 million, an increase in accounts payable and accrued expenses of $6.3 million, and an increase in the allowance for credit losses on unfunded commitments of $3.5 million, partially offset by a decrease in unearned income of $15.0 million and a reduction in tax credit capital contribution obligations of $3.2 million. Year-over-year, other liabilities increased $296.8 million, or 171.4%, as of September 30, 2022, from $173.2 million as of September 30, 2021. Exclusive of other liabilities acquired from GWB of $111.0 million, other liabilities increased $185.8 million as compared to September 30, 2021, primarily related to an increase in the derivative liability of $109.0 million.

The Company is considered to be “well-capitalized” as of September 30, 2022, having exceeded all regulatory capital adequacy requirements. During the third quarter of 2022, the Company paid regular common stock dividends of approximately $43.7 million, or $0.41 per share, and repurchased 3,279,300 shares of common stock at a weighted average price of $40.59, including costs and commissions, pursuant to its stock repurchase program that was completed during the third quarter of 2022.

CREDIT QUALITY

As of September 30, 2022, non-performing assets decreased $24.3 million, or 19.2%, to $102.4 million, compared to $126.7 million as of June 30, 2022, primarily driven by a decrease in non-accrual loans of $27.6 million, or 25.8%, and a decrease in other real estate owned of $0.4 million, or 2.4%, partially offset by an increase in loans past due 90 days or more of $3.7 million.

Criticized loans decreased $203.1 million, or 26.0%, to $576.9 million as of September 30, 2022, from $780.0 million as of June 30, 2022, driven by loan upgrades in commercial real estate, paydowns in commercial real estate and agricultural real estate portfolios, and the transfer of a commercial construction loan to held for sale, partially offset by downgrades in commercial loans.

Net loan charge-offs increased $11.7 million to $12.0 million during the third quarter of 2022 as compared to $0.3 million during the second quarter of 2022. The net loan charge-offs in the third quarter of 2022 were composed of charge-offs of $16.2 million and recoveries of $4.2 million and included $5.7 million for the workout of an acquired PCD loan specifically reserved for and $6.6 million for the workout of a metro-office commercial construction loan.

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; (vii) adjusted net interest margin; and (viii) adjusted efficiency ratio. 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. Adjusted efficiency ratio is calculated as adjusted total non-interest expense divided by adjusted revenue. 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 and PPP loan income, and it adjusts average interest-earning assets to exclude average PPP loan balances. To derive the non-GAAP financial measure identified in subclause (viii) above, the Company adjusts its total non-interest expense to exclude acquisition-related expenses, litigation accruals (recoveries), intangible amortization expenses, and other real estate owned (income), and it adjusts net interest income to include total non-interest income and exclude net gain (loss) from investment securities, Mortgage servicing right recoveries (impairments) and other identified income. 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.
