BILLINGS, Mont.–(BUSINESS WIRE)–
First Interstate BancSystem, Inc. (NASDAQ: FIBK) today reported financial results for the fourth quarter of 2021. For the quarter, the Company reported net income of $51.1 million, or $0.83 per share, which compares to net income of $47.1 million, or $0.76 per share, for the third quarter of 2021, and $46.9 million, or $0.76 per share, for the fourth quarter of 2020.

The fourth quarter 2021 earnings include pre-tax acquisition costs of $5.0 million related to the pending acquisition of Great Western Bancorp, Inc. (“Great Western”), the parent company of Great Western Bank (“GWB”), which reduced earnings by $0.06 per common share for the fourth quarter. The third quarter 2021 earnings include pre-tax acquisition costs of $6.6 million related to the pending acquisition of Great Western, and accrued expenses of $1.2 million related to the settlement of a legal claim, which reduced earnings by $0.10 per common share for the third quarter. The fourth quarter of 2020 does not include comparable aforementioned costs.

For the year ending December 31, 2021, the Company reported net income of $192.1 million, or $3.12 per share, compared to $161.2 million, or $2.53 per share, in 2020. Results in the 2021 period include pre-tax acquisition costs of $11.6 million related to the pending Great Western acquisition, which reduced earnings by $0.15 per common share for 2021.

HIGHLIGHTS

• Announced all required regulatory clearances and approvals of the shareholders of FIBK and stockholders of Great Western related to the merger of FIBK and Great Western and the merger of FIBK’s and Great Western’s respective subsidiary banks, FIB and GWB. The merger is expected to be completed on or around February 1, 2022, subject to satisfaction of customary closing conditions.
• Total deposits increased $262.3 million, or 1.6%, to $16,269.6 million as of December 31, 2021 from $16,007.3 million as of September 30, 2021, resulting in a 6.3% annualized growth rate in deposits, and increased $2,052.6 million, or 14.4% from December 31, 2020.
• Asset quality further improved in the fourth quarter of 2021. Criticized loans were $216.7 million, as of December 31, 2021, resulting in a $34.5 million, or 13.7%, decrease from $251.2 million as of September 30, 2021, and a decrease of $125.4 million, or 36.7%, from $342.1 million as of December 31, 2020.
• Non-performing assets decreased $7.7 million, or 20.6%, to $29.7 million as of December 31, 2021, from $37.4 million as of September 30, 2021 and decreased $20.8 million, or 41.2%, from $50.5 million as of December 31, 2020.
• As of December 31, 2021, 91.7% of originated Payroll Protection Program (PPP) loans were forgiven by the Small Business Administration. The Company had $100.0 million of PPP loans remaining which are expected to be forgiven in the first half of 2022.

“We continued to see healthy economic conditions across our markets in the fourth quarter, which resulted in strong deposit inflows, a record level of new loan production, and further improvement in asset quality,” said Kevin P. Riley, President and Chief Executive Officer of First Interstate BancSystem, Inc. “While we had significant growth in new loan production, this was offset by an elevated level of payoffs, which impacted our total loan growth in the quarter. As a result, we continued to have a significant amount of excess liquidity, including $2.3 billion in cash and cash equivalents, which we can redeploy into higher yielding earning assets in the future as our loan growth increases.

“Looking ahead, we believe our combination of organic and acquisitive growth will create significant additional value for shareholders. During 2022, we will be focused on efficiently integrating Great Western’s operations, beginning to realize the synergies from this merger, generating continued organic balance sheet growth through our increased exposure to faster growing markets, and capitalizing on our asset sensitive balance sheet to drive growth in net interest income and expansion in our net interest margin as interest rates increase. We believe that our strong execution on these strategic priorities this year will have us well positioned to deliver profitable growth in 2023 and in the years ahead,” said Mr. Riley.

DIVIDEND DECLARATION

On January 26, 2022, the Company’s board of directors declared a dividend of $0.41 per common share, payable on February 21, 2022, to common stockholders of record as of February 10, 2022. The dividend equates to a 4.0% annualized yield based on the $41.51 per share average closing price of the Company’s common stock as reported on NASDAQ during the fourth quarter of 2021.

PENDING ACQUISITION

On September 16, 2021, the Company entered into a definitive agreement (“Agreement”) to acquire all of the outstanding stock of Great Western, the parent company of 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. Under the terms of the Agreement, each outstanding share of Great Western will convert into the right to receive 0.8425 shares of the Company’s Class A common stock in an all-stock transaction valued at approximately $1.9 billion in the aggregate based on the closing price of the Company’s Class A common stock on December 31, 2021. Upon completion of the merger, which is expected to close on February 1, 2022, the Company will become a regional community bank with over $32.0 billion in total assets (based on September 30, 2021 financial information) with a geographic footprint spanning 14 States.

NET INTEREST INCOME

Net interest income decreased $5.1 million, or 4.0%, to $121.8 million, during the fourth quarter of 2021, compared to $126.9 million during the third quarter of 2021, primarily due to a decrease of $4.5 million in PPP loan income during the fourth quarter of 2021. Net interest income decreased $6.6 million, or 5.1%, during the fourth quarter of 2021, from $128.4 million during the fourth quarter of 2020, primarily due to a decrease of $7.0 million in PPP loan income compared to the fourth quarter of 2020.

• The Company earned a total of $9.7 million of interest income, including loan fees, on PPP loans with average balances of $200.1 million during the fourth quarter of 2021 as compared to $14.2 million of interest income, including loan fees, on PPP loans with average balances of $462.1 million during the third quarter of 2021 and $16.7 million of interest income, including loan fees, on PPP loans with average balances of $1,025.9 million during the fourth quarter of 2020. The Company had $3.8 million of unearned deferred fees related to PPP loans accrued as of December 31, 2021.

• Interest accretion attributable to the fair valuation of acquired loans from previous acquisitions contributed $1.9 million to net interest income during the fourth quarter of 2021, of which approximately $1.0 million was related to early payoffs. This compares to interest accretion of $2.3 million in net interest income during the third quarter of 2021, of which approximately $1.4 million was related to early payoffs, and $3.1 million in net interest income during the fourth quarter of 2020, of which approximately $1.6 million was related to early payoffs.

The net interest margin ratio was 2.69% for the fourth quarter of 2021 compared to 2.91% reported during the third quarter of 2021 and 3.25% during the fourth quarter of 2020. Excluding PPP income, on a quarter-over-quarter basis the net interest margin declined 15 basis points primarily because of a shift in the mix of earning assets toward investment securities and cash, and a modest reduction in loan yields. Year-over-year, the decrease in net interest margin was the result of a reduction in yields on earning assets due to the current low interest rate environment and a shift in mix of earning assets toward both investment securities and higher cash balances, the overall impact was partially offset by lower deposit costs.

PROVISION FOR (REDUCTION OF) CREDIT LOSSES

During the fourth quarter of 2021, the Company reduced its provision for credit losses by $9.5 million, compared to no change to the provision for credit losses during the third quarter of 2021, and compared to an increase to the provision for credit losses of $3.2 million during the fourth quarter of 2020.

The allowance for credit losses is updated quarterly based on the current loan portfolio, asset quality metrics, and the results of the current economic outlook. For the fourth quarter of 2021, the allowance for credit losses was impacted by net charge-offs of $2.7 million, or an annualized 0.11% of average loans outstanding, compared to net charge-offs of $0.6 million, or an annualized 0.02% of average loans outstanding, for the third quarter of 2021, and net charge-offs of $4.2 million, or an annualized 0.16% of average loans outstanding, for the fourth quarter of 2020.

The Company’s allowance for loan losses as a percentage of period-end loans was 1.31%, 1.40%, and 1.47% at December 31, 2021, September 30, 2021, and December 31, 2020, respectively. Coverage of non-performing loans increased to 441.52% at December 31, 2021, compared to 384.90% at September 30, 2021 and 300.63% at December 31, 2020, as a result of lower levels of non-performing loans and the reduction of provision for credit losses during the fourth quarter of 2021.

NON-INTEREST INCOME

Non-interest income decreased $2.3 million, or 5.8%, to $37.4 million during the fourth quarter of 2021, as compared to $39.7 million during the third quarter of 2021, primarily driven by a decrease in mortgage banking revenues that were partially offset by an increase in wealth management and swap fee revenues. Non-interest income increased $3.5 million, or 10.3%, from $33.9 million during the fourth quarter of 2020, driven by increases in wealth management revenues, swap fee revenues, and other income.

Mortgage banking revenues decreased $3.6 million, or 31.0%, to $8.0 million during the fourth quarter of 2021, as compared to $11.6 million during the third quarter of 2021. The decrease was driven by lower net realized gain-on-sale margins when compared to the third quarter of 2021, as the volume of loans sold was relatively unchanged. Included in the fourth quarter of 2021 was a $1.0 million recovery of mortgage servicing rights impairment compared to no recovery or impairment during the third quarter of 2021. Mortgage banking revenues increased $0.1 million, or 1.3%, during the fourth quarter of 2021 from $7.9 million during the fourth quarter of 2020. During the fourth quarter of 2021, loans originated for home purchases accounted for approximately 59.0% of loan production, as compared to 65.8% during the third quarter of 2021 and 51.5% during the fourth quarter of 2020.

Other service charges, commissions, and fees increased $1.4 million, or 100.0%, to $2.8 million during the fourth quarter of 2021, when compared to $1.4 million during the third quarter of 2021 and was primarily due to an increase in swap fee revenues. Other service charges, commissions, and fees increased $0.7 million, or 33.3%, during the fourth quarter of 2021 from $2.1 million during the fourth quarter of 2020.

NON-INTEREST EXPENSE

Non-interest expense decreased $3.7 million, or 3.5%, to $102.2 million during the fourth quarter of 2021, as compared to $105.9 million during the third quarter of 2021, primarily due to decreases of $1.6 million in acquisition related costs connected to the pending acquisition of GWB and other expenses of $1.4 million primarily related to the $1.2 million litigation accrual during the third quarter of 2021. Non-interest expense increased $4.8 million, or 4.9%, from $97.4 million during the fourth quarter of 2020, primarily due to $5.0 million in acquisition related costs. Exclusive of acquisition related expenses, non-interest expense decreased to $97.2 million during the fourth quarter of 2021, compared to the fourth quarter of 2020.

Salaries and wages expenses increased $0.3 million, or 0.7%, to $42.3 million during the fourth quarter of 2021, compared to $42.0 million during the third quarter of 2021 and decreased $1.3 million, or 3.0%, from $43.6 million in the fourth quarter of 2020. The decrease from the fourth quarter of 2020 was primarily the result of lower commission expenses and lower incentive-based payment accruals during the fourth quarter of 2021.

Other expenses decreased $1.4 million, or 4.6%, to $28.8 million during the fourth quarter of 2021, as compared to $30.2 million during the third quarter of 2021, primarily due to the $1.2 million accrual for a settlement of a legal claim during the third quarter of 2021. Other expenses increased $2.1 million, or 7.9%, during the fourth quarter of 2021 from $26.7 million during the fourth quarter of 2020. The increase from the fourth quarter of 2020 is primarily due to increases in professional fees, FDIC insurance premiums, and increased loan expenses during the fourth quarter of 2021.

BALANCE SHEET

Total assets increased $299.7 million, or 1.5%, to $19,671.9 million as of December 31, 2021, from $19,372.2 million as of September 30, 2021, primarily as a result of higher levels of deposits which were deployed primarily into the investment securities portfolio. Total assets increased $2,023.2 million, or 11.5%, from $17,648.7 million as of December 31, 2020. The increase from the comparable prior year period was primarily a result of higher levels of deposits, which increased 14.4%, resulting in higher levels of investment securities.

Investment securities increased $486.4 million, or 8.1%, to $6,508.1 million as of December 31, 2021, from $6,021.7 million as of September 30, 2021. Within the securities portfolio, available-for-sale securities increased $416.9 million, or 9.5%, and held-to-maturity securities increased $69.5 million, or 4.3%, during the fourth quarter of 2021. Investment securities increased $2,447.8 million, or 60.3%, from $4,060.3 million as of December 31, 2020.

Mortgage loans held for sale decreased $12.4 million, or 29.2%, to $30.1 million as of December 31, 2021, from $42.5 million as of September 30, 2021 and decreased $43.9 million, or 59.3%, as of December 31, 2021, from $74.0 million as of December 31, 2020, primarily as a result of a decrease in originations of mortgage loans held for sale related to lower refinance activity, as a result of a slow uptick in interest rates over the second half of 2021.

Loans held for investment decreased $290.8 million, or 3.0%, to $9,331.7 million as of December 31, 2021, from $9,622.5 million as of September 30, 2021, and decreased $475.8 million, or 4.9%, from $9,807.5 million as of December 31, 2020.

Excluding the impact of PPP loans, loans held for investment as of December 31, 2021, decreased from September 30, 2021, primarily due to decreases in the real estate and consumer loan portfolios, and increased from December 31, 2020 due to increases in the real estate loan portfolios that were offset by declines in consumer, agriculture, and commercial loans.

Total real estate loans decreased $75.4 million, or 1.1%, to $6,731.4 million as of December 31, 2021, from $6,806.8 million as of September 30, 2021, primarily driven by decreases in construction loans of $131.0 million, or 11.5%, residential loans of $16.7 million, or 1.1%, and agricultural loans of $16.0 million, or 7.0%. These decreases were offset by an increase in commercial real estate loans of $88.3 million, or 2.3%. The increase in commercial real estate loans and decrease in construction loans is reflective of construction loans migrating to permanent financing.

Total real estate loans increased $331.9 million, or 5.2%, from December 31, 2020. Growth within the real estate loan portfolio is attributable to increases in commercial real estate loans of $228.3 million, or 6.1%, residential loans of $141.9 million, or 10.2%, and residential construction loans of $11.1 million, or 4.4%. Growth was offset by a decrease in commercial construction loans of $25.5 million, or 4.9%, land acquisition and development construction loans of $17.2 million, or 6.5%, and agricultural real estate loans of $6.7 million, or 3.0%.

Total consumer loans decreased $22.1 million, or 2.3%, to $931.7 million as of December 31, 2021, from $953.8 million as of September 30, 2021, with a decrease in indirect loans of $19.2 million, or 2.5% and direct loans of $3.7 million, or 2.8%. These decreases were partially offset by an increase of $0.8 million, or 1.2%, in the credit card portfolio, as of December 31, 2021 from September 30, 2021. Total consumer loans decreased $94.2 million, or 9.2%, from $1,025.9 million as of December 31, 2020 across all consumer loan portfolios. Indirect loans decreased $67.5 million, or 8.4%, direct loans decreased $21.4 million, or 14.2%, and credit card loans decreased $5.3 million, or 7.5%, as of December 31, 2021 from December 31, 2020.

Commercial loans decreased $193.2 million, or 11.6%, to $1,475.5 million as of December 31, 2021, from $1,668.7 million as of September 30, 2021. Commercial loans included $100.0 million of PPP loans as of December 31, 2021. During the fourth quarter of 2021, $193.4 million of PPP loans were forgiven by the Small Business Administration. Net of the impact of PPP loans, commercial loans increased $0.2 million from September 30, 2021. Commercial loans decreased $678.4 million, or 31.5%, from $2,153.9 million as of December 31, 2020. The decrease from December 31, 2020 is primarily due to a decrease of $639.8 million of PPP loans and pay-downs within the portfolio.

Agricultural operating loans decreased $8.5 million, or 4.0%, to $203.9 million as of December 31, 2021, from $212.4 million as of September 30, 2021 due to seasonal fluctuations. Agricultural operating loans decreased $43.7 million, or 17.6%, from $247.6 million as of December 31, 2020, primarily due to client payoffs and pay-downs within the portfolio.

Premises and equipment increased $2.3 million, or 0.8%, to $299.6 million as of December 31, 2021, from $297.3 million as of September 30, 2021 and decreased $12.7 million, or 4.1%, as of December 31, 2021, from $312.3 million as of December 31, 2020. The decrease from December 31, 2020 is primarily related to the disposition of five properties.

Other assets decreased $9.4 million, or 3.5%, to $257.3 million as of December 31, 2021, from $266.7 million as of September 30, 2021, primarily due to a decrease in the value of interest rate swap contracts of $5.4 million and accrued receivables of $9.2 million. Other assets increased $18.9 million, or 7.9%, as of December 31, 2021, from $238.4 million as of December 31, 2020, primarily due to an increase in accrued receivables and tax credits.

Total deposits increased $262.3 million, or 1.6%, to $16,269.6 million as of December 31, 2021, from $16,007.3 million as of September 30, 2021, primarily related to increases in interest-bearing demand and savings deposits. These increases were partially offset by decreases in non-interest bearing business deposits and interest-bearing time deposits. Total deposits increased $2,052.6 million, or 14.4%, from $14,217.0 million as of December 31, 2020, primarily related to increases in non-interest-bearing business deposits and interest-bearing demand and savings deposits. These increases were partially offset by decreases in interest-bearing time deposits.

Fluctuations in repurchase agreement balances correspond with fluctuations in the liquidity of the Company’s clients.

Other liabilities decreased $8.0 million, or 4.6%, to $165.2 million as of December 31, 2021, from $173.2 million as of September 30, 2021, primarily due to a decrease in the deferred tax liability of $8.1 million. Year-over-year, other liabilities decreased $15.9 million, or 8.8%, as of December 31, 2021, from $181.1 million as of December 31, 2020, primarily due to a decrease of $17.9 million in the deferred tax liability and timing of accrued expenses and payables.

The loans held for investment to deposit ratio decreased to 57.4%, as of December 31, 2021, compared to 60.1% and 69.0% as of September 30, 2021 and December 31, 2020, respectively.

The Company is considered to be “well-capitalized” as of December 31, 2021, having exceeded all regulatory capital adequacy requirements. During the fourth quarter of 2021, the Company paid regular common stock dividends of approximately $25.4 million, or $0.41 per share, and did not make any share repurchases of common stock pursuant to its previously announced stock repurchase program.

CREDIT QUALITY

As of December 31, 2021, non-performing assets decreased $7.7 million, or 20.6%, to $29.7 million, compared to $37.4 million as of September 30, 2021, primarily due to a decrease in non-accrual loans of $5.0 million, or 16.7%, a decrease in accruing loans past due 90 days or more of $2.4 million, or 46.2%, and a decrease in other real estate owned of $0.3 million, or 13.0%.

Criticized loans decreased $34.5 million, or 13.7%, to $216.7 million as of December 31, 2021, from $251.2 million as of September 30, 2021, driven primarily by upgrades in commercial real estate and loan pay downs in the commercial real estate and agricultural real estate loan portfolios. As of December 31, 2021, criticized loans decreased $125.4 million from $342.1 million as of December 31, 2020.

Net loan charge-offs increased $2.1 million, or 350.0%, to $2.7 million during the fourth quarter of 2021 as compared to $0.6 million during the third quarter of 2021. The net loan charge-offs in the fourth quarter of 2021 were composed of charge-offs of $4.8 million and recoveries of $2.1 million. Net loan charge-offs during the fourth quarter of 2020 were $4.2 million.

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; and (vi) return on average tangible common stockholders’ equity. 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. 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 foregoing capital adequacy measures to exclude goodwill and other intangible assets (except mortgage servicing rights), adjusts its non-interest expense to exclude acquisition related expenses, and adjusts its net interest margin ratio to exclude the impact of the recovery of charged-off interest and 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 the acquisition costs and 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.
