BILLINGS, Mont.--(BUSINESS WIRE)--First Interstate BancSystem, Inc. (NASDAQ: FIBK) (the “Company”) today reported financial results for the first quarter of 2026. For the quarter, the Company reported net income of $60.2 million, or $0.61 per diluted share, which compares to net income of $108.8 million, or $1.08 per diluted share, for the fourth quarter of 2025 and net income of $50.2 million, or $0.49 per diluted share, for the first quarter of 2025.
HIGHLIGHTS
Net interest margin increased to 3.41% for the first quarter of 2026, a 5-basis point increase from the fourth quarter of 2025 and a 22-basis point increase from the first quarter of 2025. Other borrowed funds were zero as of March 31, 2026 and December 31, 2025 as compared to $960.0 million as of March 31, 2025. Net charge-offs decreased $19.7 million to $2.4 million, or an annualized 0.06% of average loans outstanding, as of March 31, 2026, from $22.1 million, or an annualized 0.56% of average loans outstanding, as of December 31, 2025, and decreased $6.6 million from $9.0 million, or an annualized 0.21% of average loans outstanding, as of March 31, 2025. Criticized loans decreased $18.6 million to $1,033.2 million as of March 31, 2026, compared to $1,051.8 million as of December 31, 2025, and increased $7.1 million, compared to $1,026.1 million as of March 31, 2025. Non-performing assets increased $24.2 million, or 17.5%, to $162.5 million as of March 31, 2026, from $138.3 million as of December 31, 2025 and decreased $35.9 million, or 18.1%, from $198.4 million as of March 31, 2025. Total deposits decreased $205.3 million to $21,883.0 million as of March 31, 2026, compared to $22,088.3 million as of December 31, 2025 primarily due to decreases in all deposit categories except for savings deposits during the first quarter. Total deposits decreased $849.8 million, or 3.7% from March 31, 2025 with decreases in all deposit categories except for savings deposits primarily driven by the Arizona and Kansas branch sales which consisted of $641.6 million of deposits. During the first quarter of 2026, the Company repurchased 2.39 million shares of common stock for a total repurchase of approximately $84.0 million, in addition to the Company’s repurchase of approximately 3.65 million shares of common stock through December 31, 2025 for a total repurchase of approximately $117.6 million. On January 27, 2026, the board of directors authorized an increase to the repurchase program of an additional $150.0 million, or a total of $300.0 million authorized since its adoption in August of 2025. Common equity tier 1 capital ratio decreased 8 basis points during the first quarter of 2026 to 14.30%, compared to the fourth quarter of 2025, primarily as a result of shares repurchased during first quarter, partially offset by lower risk-weighted assets primarily driven by lower loan balances. “We are pleased to see continued improvement in our net interest margin and continue to execute on our previously announced share repurchase authorization,” said James A Reuter, President and Chief Executive Officer of the Company. “We are encouraged with the underlying momentum in the business as we enter the second quarter, with a strong commercial pipeline and ongoing fixed asset repricing supporting our confidence in continued earnings improvement.”
DIVIDEND DECLARATION
On April 28, 2026, the Company’s board of directors declared a dividend of $0.47 per common share, payable on May 21, 2026, to common stockholders of record as of May 11, 2026. The dividend equates to a 5.3% annualized yield based on the $35.76 per share average closing price of the Company’s common stock as reported on NASDAQ during the first quarter of 2026.
NET INTEREST INCOME
Net interest income decreased $5.7 million to $200.7 million during the first quarter of 2026, compared to net interest income of $206.4 million during the fourth quarter of 2025. Net interest income decreased $4.3 million, or 2.1%, during the first quarter of 2026 compared to the first quarter of 2025. The quarterly decline from the fourth quarter of 2025 was primarily driven by lower interest income due to reduced loan yields and balances, and fewer accrual days, partially offset by higher investment balances and yields and lower interest expense due to reduced deposit balances and rates. Year-over-year lower interest earning assets and interest bearing liabilities were partially influenced by the reduction in loans and deposits related to the sale of the Arizona and Kansas branches during the fourth quarter of 2025, which resulted in a reduction of net interest income, in the first quarter of 2026.
Interest accretion attributable to the fair value of acquired loans, related to prior acquisitions, contributed to net interest income during the first quarter of 2026, the fourth quarter of 2025, and the first quarter of 2025, in the amounts of $3.1 million, $2.6 million, and $4.7 million, respectively.
Net interest margin ratio was 3.41% for the first quarter of 2026, compared to 3.36% during the fourth quarter of 2025, and 3.19% during the first quarter of 2025. Net FTE (fully-taxable equivalent) interest margin ratio1 was 3.43% for the first quarter of 2026, compared to 3.38% during the fourth quarter of 2025, and 3.22% during the first quarter of 2025. Excluding interest accretion from the fair value of acquired loans, the adjusted net FTE interest margin ratio1, was 3.38%, an increase of 4 basis points from the prior quarter, primarily driven by higher yields on higher average investment security balances and lower rates on lower interest bearing deposits, partially offset by lower loan yields on lower average loan balances. Excluding interest accretion from the fair value of acquired loans, on a year-over-year basis, the adjusted net FTE interest margin ratio increased 24 basis points, primarily as a result of lower interest expense resulting from decreased other borrowed funds balances.
PROVISION FOR CREDIT LOSSES
During the first quarter of 2026, the Company recorded a provision for credit losses of $6.7 million. This compares to a provision for credit losses of $7.1 million and $20.0 million during the fourth quarter of 2025 and the first quarter of 2025, respectively.
For the first quarter of 2026, net loan charge-offs were $2.4 million, or an annualized 0.06% of average loans outstanding, compared to net loan charge-offs of $22.1 million, or an annualized 0.56% of average loans outstanding, for the fourth quarter of 2025 and net loan charge-offs of $9.0 million, or an annualized 0.21% of average loans outstanding, for the first quarter of 2025. Net loan charge-offs in the first quarter of 2026 were composed of charge-offs of $6.5 million offset by recoveries of $4.1 million. Net loan charge-offs in the fourth quarter of 2025 were composed of charge-offs of $24.5 million, primarily related to one loan of $15.8 million, which were offset by recoveries of $2.4 million. Net loan charge-offs in the first quarter of 2025 were composed of charge-offs of $10.8 million, which were offset by recoveries of $1.8 million.
The Company’s allowance for credit losses as a percentage of period-end loans held for investment was 1.33% at March 31, 2026, compared to 1.26% at December 31, 2025 and 1.24% at March 31, 2025. Coverage of non-performing loans decreased to 125.6% at March 31, 2026, compared to 141.9% at December 31, 2025 and increased from 110.5% at March 31, 2025.

Noninterest income was $41.1 million for the first quarter of 2026, decreasing $65.5 million compared to the fourth quarter of 2025 and decreasing $0.9 million compared to the first quarter of 2025. The decrease from the fourth quarter of 2025 was primarily due to the $62.7 million gain recorded in other income from the sale of the Arizona and Kansas branches during the fourth quarter of 2025.
Payment services revenues decreased $0.6 million and $1.5 million during the first quarter of 2026 compared to the fourth quarter of 2025 and the first quarter of 2025, respectively. The year-over-year decrease was mainly the result of lower consumer credit card interchange during the first quarter of 2026 as compared to the first quarter of 2025, related to the outsourcing of consumer credit cards in the second quarter of 2025.

The Company’s noninterest expense was $157.6 million for the first quarter of 2026, a decrease of $9.1 million from the fourth quarter of 2025 and a decrease of $3.0 million from the first quarter of 2025.
Salary and wages expense decreased $6.3 million to $68.5 million during the first quarter of 2026 compared to the fourth quarter of 2025, primarily due to lower short-term incentive accruals of $2.9 million and lower severance accruals of $2.9 million during the first quarter of 2026. Salaries and wages expense decreased $0.1 million to $68.5 million during the first quarter of 2026 compared to $68.6 million during the first quarter of 2025.
Employee benefit expenses increased $2.7 million to $21.2 million during the first quarter of 2026, compared to $18.5 million during the fourth quarter of 2025, primarily due to the seasonal reset of payroll taxes, partially offset by lower long-term incentives and medical insurance costs. Employee benefit expenses increased $1.2 million from $20.0 million during the first quarter of 2025, primarily due to higher health insurance costs of $3.1 million, partially offset by $1.6 million of lower long-term incentive accruals during the first quarter of 2026.
Occupancy and equipment expenses decreased $1.0 million to $18.6 million during the first quarter of 2026, compared to $19.6 million during the fourth quarter of 2025, primarily due to higher depreciation expense as a result of the impairments in the fourth quarter of 2025 for the pending branch closures that occurred in the first quarter of 2026. Occupancy and equipment expenses increased $0.1 million during the first quarter of 2026 from $18.7 million during the first quarter of 2025.
Other expenses decreased $3.3 million during the first quarter of 2026 compared to the fourth quarter of 2025, primarily due to a decrease of $1.5 million in professional fees and decreases in donations and various other expense categories. Other expenses decreased $2.3 million during the first quarter of 2026 compared to the first quarter of 2025, primarily due to a decrease in FDIC special assessment accruals.
Other real estate owned expense, net decreased $1.1 million during the first quarter of 2026 compared to the fourth quarter of 2025 and decreased $1.6 million during the first quarter of 2026 compared to the first quarter of 2025, primarily due to a positive fair value adjustment to a commercial property.
BALANCE SHEET
Total assets decreased $213.8 million, or 0.8%, to $26,426.8 million as of March 31, 2026, from $26,640.6 million as of December 31, 2025, primarily due to decreases in loans and cash and cash equivalents, which were partially offset by an increase in investment securities. Total assets decreased $1,853.0 million from $28,279.8 million as of March 31, 2025, primarily due to a decrease in loans which was partially driven by the sale of the branches in Arizona and Kansas during the fourth quarter of 2025. The funds from the loan declines were partially used to pay down debt, which were partially offset by increases in investment securities and cash and cash equivalents.
Investment securities increased $379.8 million to $8,010.0 million as of March 31, 2026, from $7,630.2 million as of December 31, 2025, primarily resulting from purchases of investment securities, partially offset by pay-downs, maturities, called securities, and a $23.5 million decrease in fair market values during the first quarter. Investment securities increased $506.2 million from $7,503.8 million as of March 31, 2025, primarily resulting from purchases of investment securities and a $93.6 million increase in fair market values during the period, partially offset by pay-downs, maturities, and called securities.

The decline in loans was impacted by $58.1 million of continued amortization of the indirect portfolio for which the Company stopped originating loans during the first quarter of 2025, agricultural loan payoffs, and other loan paydowns and payoffs during the first quarter of 2026.
The ratio of loans held for investment to deposits was 67.3%, as of March 31, 2026, compared to 68.8% as of December 31, 2025 and 76.4% as of March 31, 2025.
Total deposits decreased $205.3 million to $21,883.0 million as of March 31, 2026, from $22,088.3 million as of December 31, 2025, primarily due to decreases in all deposit categories except for savings deposits during the first quarter. Total deposits decreased $849.8 million, or 3.7%, from $22,732.8 million as of March 31, 2025, with decreases in all deposit categories except for savings deposits during the first quarter of 2026, primarily driven by the Arizona and Kansas branch sales during the fourth quarter of 2025 which consisted of $641.6 million of deposits.
Other borrowed funds is composed of variable-rate, overnight and fixed-rate borrowings with remaining contractual tenors of up to one year through the Federal Home Loan Bank. Other borrowed funds were zero as of March 31, 2026 and December 31, 2025, respectively. Other borrowed funds decreased $960.0 million from March 31, 2025. The decrease was funded by cash flows from paydowns and maturities of investment securities and loans.
The Company is considered to be “well-capitalized” as of March 31, 2026, having exceeded all regulatory capital adequacy requirements. During the first quarter of 2026, the Company paid regular common stock dividends of approximately $45.7 million, or $0.47 per share and repurchased approximately 2.4 million shares of common stock at a weighted average price of $35.09 per share pursuant to its stock repurchase program.
CREDIT QUALITY
As of March 31, 2026, non-performing assets increased $24.2 million, or 17.5%, to $162.5 million, compared to $138.3 million as of December 31, 2025, primarily as a result of an increase in non-accrual loans related to a single client relationship comprised of $20.2 million in commercial and commercial real estate non-accrual loans and an increase of $3.2 million in OREO.
Criticized loans decreased $18.6 million, or 1.8%, to $1,033.2 million as of March 31, 2026, from $1,051.8 million as of December 31, 2025, primarily as a result of upgrades as well as paydowns and payoffs in the portfolio.
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) net FTE interest income; (viii) net FTE interest margin ratio; (ix) adjusted net FTE interest income; and (x) adjusted net FTE interest margin 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 total stockholders’ equity less average goodwill and other intangible assets (excluding mortgage servicing rights). Return on average tangible common stockholders’ equity is calculated as annualized net income available to common shareholders divided by average tangible common stockholders’ equity. Net FTE interest income is calculated as net interest income, adjusted to include its FTE interest income. Net FTE interest margin ratio is calculated as net FTE interest income divided by average interest earning assets. Adjusted net FTE interest income is calculated as net FTE interest income less purchase accounting interest accretion on acquired loans. Adjusted net FTE interest margin ratio is calculated as annualized adjusted net FTE interest income divided by 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), adjusts its GAAP net interest income to include fully taxable equivalent adjustments and further adjusts its net interest income on a fully taxable equivalent basis to exclude purchase accounting interest accretion. 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.
Cautionary Note Regarding Forward-Looking Statements and Factors that Could Affect Future Results
This press release contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Rule 175 promulgated thereunder, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and Rule 3b-6 promulgated thereunder, that involve inherent risks and uncertainties. Any statements about our plans, objectives, expectations, strategies, beliefs, or future performance, financial condition, results of operations, investment portfolio, market position, or events constitute forward-looking statements. Such statements are identified by words or phrases such as “believes,” “expects,” “anticipates,” “plans,” “trends,” “objectives,” “continues”, “projected,” as well as the negative forms of those words or similar expressions, or future or conditional verbs such as “will,” “would,” “should,” “could,” “might,” “may,” or similar expressions. Forward-looking statements involve known and unknown risks, uncertainties, assumptions, estimates and other important factors that could cause actual results to differ materially from any results, performance or events expressed or implied by such forward-looking statements. Furthermore, the following factors, among others, may cause actual results to differ materially from current expectations in the forward-looking statements, including those set forth in this press release:
new or changes in existing governmental regulations or in the way such regulations are interpreted or enforced; negative developments in the banking industry and increased regulatory scrutiny; tax legislative initiatives or assessments; more stringent capital requirements, to the extent they may become applicable to us; changes in accounting standards; any failure to comply with applicable laws and regulations, including, but not limited to, the Community Reinvestment Act and fair lending laws, the USA PATRIOT ACT of 2001, the Office of Foreign Asset Control guidelines and requirements, the Bank Secrecy Act, and the related Financial Crimes Enforcement Network and Federal Financial Institutions Examination Council Guidelines and regulations; federal deposit insurance assessment rate increases; lending risks and risks associated with loan portfolio concentrations; a decline in economic conditions that could reduce demand for our products and services and negatively impact the credit quality of loans; credit losses on loans exceeding estimates; potential effects on the U.S. economy resulting from the implementation of governmental policies, including tax regulations and changes to United States trade policies, including the imposition of tariffs and retaliatory tariffs and geopolitical uncertainty; the soundness of other financial institutions; the ability to meet cash flow needs and availability of financing sources for working capital and other needs; a loss of deposits or a change in product mix that increases the Company’s funding costs; inability to access funding or to monetize liquid assets; changes in interest rates; interest rate effect on the value of our investment securities; cybersecurity risks, including business disruptions from denial-of-service attacks, network intrusions, business e-mail compromise, and other malicious behavior that could result in the disclosure of confidential information; privacy, information security, and data protection laws, rules, and regulations that affect or limit how we collect and use personal information or otherwise have an adverse effect on us; the potential impairment of our goodwill and other intangible assets; our reliance on third parties that provide key components of our business infrastructure; events that may tarnish our reputation; mainstream and social media contagion; the loss of the services of key members of our management team and directors; our ability to attract and retain qualified employees to operate our business; costs associated with repossessed properties, including potential environmental remediation; the effectiveness of our operational processes, policies and procedures, and internal control over financial reporting; our ability to implement technology-facilitated products and services or be successful in marketing these products and services to our clients; the development and use of artificial intelligence ("AI"); risks related to acquisitions, mergers, strategic partnerships, divestitures, and other transactions; competition from new or existing financial institutions and non-banks; investing in technology; incurrence of significant costs related to mergers and related integration activities; the volatility in the price and trading volume of our common stock; “anti-takeover” provisions in our certificate of incorporation and regulations, which may make it more difficult for a third party to acquire control of us even in circumstances that could be deemed beneficial to stockholders; changes in our dividend policy or our ability to pay dividends; the possibility that we may fail to realize the anticipated benefits of our stock repurchase program; our common stock not being an insured deposit; the potential dilutive effect of future equity issuances; the subordination of our common stock to our existing and future indebtedness; the effect of global conditions, earthquakes, volcanoes, tsunamis, floods, fires, drought, and other natural catastrophic events; and the impact of climate change and environmental sustainability matters.

The regulatory capital ratios presented include the assumption of the transitional method as a result of legislation by the United States Congress to provide relief for the economy and financial institutions in the United States from the COVID‑19 pandemic. The referenced relief ended on December 31, 2024, which allowed a total five-year phase-in of the impact of CECL on capital.
