•Other borrowed funds decreased to zero as of September 30, 2025, from $250.0 million as of June 30, 2025 and from $2,080.0 million as of September 30, 2024.
•Non-performing assets decreased $11.9 million, or 6.0%, to $185.6 million as of September 30, 2025, from $197.5 million as of June 30, 2025 and increased $6.7 million, or 3.7%, from $178.9 million as of September 30, 2024.
•Net charge-offs decreased $3.5 million, or 60.3%, to $2.3 million, or an annualized 0.06% of average loans outstanding, as of September 30, 2025, from $5.8 million, or an annualized 0.14% of average loans outstanding, as of June 30, 2025, and decreased $25.1 million, or 91.6%, from $27.4 million, or an annualized 0.60% of average loans outstanding, as of September 30, 2024.
•Criticized loans decreased $38.9 million to $1,164.1 million as of September 30, 2025, compared to $1,203.0 million as of June 30, 2025, and increased $560.8 million, compared to $603.3 million as of September 30, 2024.
•Total deposits decreased $25.6 million at September 30, 2025 from June 30, 2025, with noninterest bearing deposits decreasing by $23.3 million and interest bearing deposits decreasing $2.3 million. Total deposits decreased $259.1 million, or 1.1% from September 30, 2024.
•Since the adoption of its $150 million stock repurchase program on August 28, 2025, the Company repurchased approximately 0.8 million shares of common stock through September 30, 2025 and an additional 1.0 million shares of common stock through October 28, 2025, for a total repurchase of approximately $57.2 million through October 28, 2025 or approximately 1.8 million shares.
•Capital ratios continued to improve during the third quarter of 2025, with our common equity tier 1 capital ratio increasing 47 basis points to 13.90%, compared to the second quarter of 2025, primarily as a result of lower risk-weighted assets.
“We continue to execute on our strategic plan, announced earlier this year, to focus on organic growth and leverage our strong balance sheet to support our customers. Our net interest margin continued to improve, and we maintained a clear focus on managing expenses prudently, with a goal to drive long-term, profitable growth,” said James A Reuter, President and Chief Executive Officer of the Company. “I am especially pleased with the team of senior leaders and relationship bankers, both from within First Interstate, and those who have joined us from other institutions, who are driving our plan forward. Our strong and flexible liquidity and capital levels provide a solid foundation to drive growth and returns for our shareholders.”
DIVIDEND DECLARATION
On October 28, 2025, the Company’s board of directors declared a dividend of $0.47 per common share, payable on November 20, 2025, to common stockholders of record as of November 10, 2025. The dividend equates to a 6.0% annualized yield based on the $31.11 per share average closing price of the Company’s common stock as reported on NASDAQ during the third quarter of 2025.
NET INTEREST INCOME
Net interest income decreased $0.4 million, or 0.2%, to $206.8 million during the third quarter of 2025, compared to net interest income of $207.2 million during the second quarter of 2025. Net interest income increased $1.3 million, or 0.6%, during the third quarter of 2025 compared to the third quarter of 2024, primarily due to a decrease in interest expense resulting from a decrease in average other borrowed funds balances, partially offset by lower interest income on investment securities as a result of a decrease in average rates and average investment security balances and as a result of a decrease in average loan balances.
Interest accretion attributable to the fair value of acquired loans contributed to net interest income during the third quarter of 2025, the second quarter of 2025, and the third quarter of 2024, in the amounts of $3.5 million, $4.2 million, and $4.4 million, respectively.
Net interest margin ratio was 3.34% for the third quarter of 2025, compared to 3.30% during the second quarter of 2025, and 3.01% during the third quarter of 2024. Net FTE (fully-taxable equivalent) interest margin ratio1 was 3.36% for the third quarter of 2025, compared to 3.32% during the second quarter of 2025, and 3.04% during the third quarter of 2024. Excluding interest accretion from the fair value of acquired loans, the adjusted net FTE interest margin ratio1, was 3.30%, an increase of 4 basis points from the prior quarter, primarily driven by lower interest expense resulting from decreased borrowings. Excluding interest accretion from the fair value of acquired loans, on a year-over-year basis, the adjusted net FTE interest margin ratio increased 33 basis points, primarily as a result of lower interest expense resulting from decreased other borrowed funds balances, and a favorable change in the mix of earning assets.
PROVISION FOR CREDIT LOSSES
The Company had no provision for credit losses during the third quarter of 2025. This compares to a reduction of provision for credit losses of $0.3 million and provision for credit losses of $19.8 million during the second quarter of 2025 and the third quarter of 2024, respectively.
For the third quarter of 2025, net charge-offs were $2.3 million, or an annualized 0.06% of average loans outstanding, compared to net charge-offs of $5.8 million, or an annualized 0.14% of average loans outstanding, for the second quarter of 2025 and net charge-offs of $27.4 million, or an annualized 0.60% of average loans outstanding, for the third quarter of 2024. Net loan charge-offs in the third quarter of 2025 were composed of charge-offs of $6.7 million, which was offset by recoveries of $4.4 million. Net loan charge-offs in the second quarter of 2025 were composed of charge-offs of $13.0 million, which was offset by recoveries of $7.2 million. Net loan charge-offs in the third quarter of 2024 were composed of charge-offs of $29.1 million, which was offset by recoveries of $1.7 million.
The Company’s allowance for credit losses as a percentage of period-end loans held for investment was 1.30% at September 30, 2025, compared to 1.28% at June 30, 2025 and 1.25% at September 30, 2024. Coverage of non-performing loans increased to 113.0% at September 30, 2025, compared to 108.0% at June 30, 2025 and 129.2% at September 30, 2024.

1 Represents a Non-GAAP financial measure. See “Non-GAAP Financial Measures” and the corresponding table captioned “Non-GAAP Financial Measures” included below for an explanation of the manner in which this measure is calculated and a reconciliation to this measure’s most directly comparable GAAP financial measure.
Payment services revenues decreased $1.0 million and $1.9 million during the third quarter of 2025 compared to the second quarter of 2025 and the third quarter of 2024, respectively. These decreases were mainly the result of lower consumer credit card interchange during the third quarter of 2025 as compared to the second quarter of 2025 and the third quarter of 2024, related to the outsourcing of consumer credit cards in the second quarter of 2025.
Other income increased $3.1 million to $5.9 million during the third quarter of 2025, compared to $2.8 million during the second quarter of 2025. The increase is primarily due to the second quarter of 2025 valuation allowance for loans transferred from loans held for investment to loans held for sale related to the then pending sale of the Arizona and Kansas branches, which transaction closed on October 10, 2025 subsequent to the third quarter of 2025, partially offset by the gain related to the sale of the consumer credit card loan portfolio during the second quarter of 2025. Other income decreased $1.7 million from $7.6 million during the third quarter of 2024, primarily due to a gain-on-sale of assets during the third quarter of 2024.

The Company’s noninterest expense was $157.9 million for the third quarter of 2025, an increase of $2.8 million from the second quarter of 2025 and a decrease of $1.5 million from the third quarter of 2024.
Salary and wages expense increased $1.2 million during the third quarter of 2025 compared to the second quarter of 2025 and decreased $4.7 million compared to the third quarter of 2024. The increase when compared to the second quarter of 2025 was primarily due to higher salaries and short-term incentive accruals during the third quarter of 2025. The decrease when compared to the third quarter of 2024 was primarily due to a $3.8 million accrual related to the CEO transition in the third quarter of 2024 and $3.1 million of lower short-term incentive accruals, which were partially offset by higher salaries during the third quarter of 2025.
Employee benefit expenses increased $0.3 million to $18.2 million during the third quarter of 2025, compared to $17.9 million during the second quarter of 2025. Employee benefit expenses decreased $1.5 million from $19.7 million during the third quarter of 2024, primarily due to lower health insurance costs.
Occupancy and equipment expenses decreased $0.1 million to $18.5 million during the third quarter of 2025, compared to $18.6 million during the second quarter of 2025. Occupancy and equipment expenses increased $1.5 million, or 8.8%, during the third quarter of 2025 from $17.0 million during the third quarter of 2024, primarily due to an increase in maintenance and repairs and janitorial costs.
Other expenses increased $1.4 million during the third quarter of 2025 compared to the second quarter of 2025 and increased $3.4 million during the third quarter of 2025 compared to the third quarter of 2024. The increase compared to the second quarter of 2025 was primarily related to the write off of the issuance costs of the $100.0 million of aggregate principle amount of 5.25% fixed-to-floating rate subordinated notes due 2030 that were called for redemption in August 2025. The increase from the third quarter of 2024 was primarily due to increases in legal and consulting services in the third quarter of 2025.
BALANCE SHEET
Total assets decreased $233.5 million, or 0.8%, to $27,332.9 million as of September 30, 2025, from $27,566.4 million as of June 30, 2025 and decreased $2,262.6 million, or 7.6%, from $29,595.5 million as of September 30, 2024, primarily due to decreases in investment securities and loans, the funds from which were partially used to pay down debt, fund decreases in deposits, and securities sold under repurchase agreements.
Investment securities decreased $6.4 million, or 0.1%, to $7,305.8 million as of September 30, 2025, from $7,312.2 million as of June 30, 2025, primarily resulting from pay-downs, maturities, and called securities, partially offset by a $38.2 million increase in fair market values and $725.2 million in purchases of investment securities during the third quarter. Investment securities decreased $969.8 million, or 11.7%, from $8,275.6 million as of September 30, 2024, primarily resulting from called securities and normal pay-downs and maturities, partially offset by a $67.6 million increase in fair market values and $803.5 million in purchases of investment securities during the period.

All values are in US Dollars.
The decline in loans was impacted by $66.8 million of continued amortization of the indirect portfolio for which the Company stopped originating loans during the first quarter of 2025 and larger loan paydowns and payoffs during the third quarter of 2025.
The ratio of loans held for investment to deposits was 70.1%, as of September 30, 2025, compared to 72.3% as of June 30, 2025 and 78.8% as of September 30, 2024.
Total deposits decreased $25.6 million to $22,605.0 million as of September 30, 2025, from $22,630.6 million as of June 30, 2025, primarily due to decreases in interest bearing demand, time, other, and noninterest bearing deposits that were partially offset by increases in other interest bearing deposit categories. Total deposits decreased $259.1 million, or 1.1%, from $22,864.1 million as of September 30, 2024, with decreases in noninterest bearing and time, other interest bearing deposits, which were partially offset by increases in other interest bearing deposit categories.
Securities sold under repurchase agreements decreased $24.1 million, or 4.7%, to $485.2 million as of September 30, 2025, from $509.3 million as of June 30, 2025, and decreased $72.0 million, or 12.9%, from $557.2 million as of September 30, 2024, resulting from normal fluctuations in the liquidity needs of the Company’s clients.
Long-term debt decreased $105.8 million to $146.2 million as of September 30, 2025, from $252.0 million as of June 30, 2025, primarily due to the payoff of $100.0 million of subordinated notes in the third quarter of 2025. Long-term debt increased $8.9 million, from $137.3 million as of September 30, 2024.
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 decreased $250.0 million, or 100.0%, to zero as of September 30, 2025, from $250.0 million as of June 30, 2025. The decrease was funded by cash flows from paydowns and maturities of loans. Other borrowed funds decreased $2,080.0 million from September 30, 2024. The decrease was funded by cash flows from paydowns and maturities of investment securities and loans, which were utilized for the pay-off of the $1.0 billion Bank Term Funding Program in December 2024 and Federal Home Loan Bank borrowings.
The Company is considered to be “well-capitalized” as of September 30, 2025, having exceeded all regulatory capital adequacy requirements. During the third quarter of 2025, the Company paid regular common stock dividends of approximately $49.1 million, or $0.47 per share and repurchased approximately 0.8 million shares of common stock at a weighted average price of $32.58 per share pursuant to its stock repurchase program discussed above.
CREDIT QUALITY
As of September 30, 2025, non-performing assets decreased $11.9 million, or 6.0%, to $185.6 million, compared to $197.5 million as of June 30, 2025, primarily as a result of a decrease in non-accrual loans.
Criticized loans decreased $38.9 million, or 3.2%, to $1,164.1 million as of September 30, 2025, from $1,203.0 million as of June 30, 2025, primarily as a result of both upgrades and downgrades 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 This presentation 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, 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 or market position, or events constitute forward-looking statements. Such statements are generally 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,” “seek,” “might,” “may”, as well as the negative forms of those words 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. 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 presentation: 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 increases; lending risks and risks associated with loan sector concentrations; a decline in economic conditions that could reduce demand for our products and services and negatively impact the credit quality of loans; loan credit losses exceeding estimates; effects on the U.S. economy resulting from the implementation of policies by and geopolitical uncertainty from the new presidential administration, including tax regulations and changes to United States trade policies, including the imposition of tariffs and retaliatory tariffs; 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 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 other companies 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; 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 foregoing factors are not necessarily all of the factors that could cause our actual results, performance or achievements to differ materially from those expressed in or implied by any of our forward-looking statements. Other unpredictable factors also could harm our results. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements set forth above and included in our periodic reports filed with the Securities and Exchange Commission, or SEC, under the Securities Exchange Act of 1934, as amended, under the caption “Risk Factors”.

NON-GAAP FINANCIAL MEASURES 19 In addition to results presented in accordance with accounting principles generally accepted in the United States of America, or GAAP, this presentation 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) net interest income on a fully taxable equivalent basis; (vi) adjusted net interest income on a fully taxable equivalent basis; (vii) net interest margin on a fully taxable equivalent basis; and (viii) adjusted net interest margin on a fully taxable equivalent basis. 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. Net interest income on a fully taxable equivalent basis is calculated as net interest income, adjusted to include its fully taxable equivalent interest income. Adjusted net interest income on a fully taxable equivalent basis is calculated as net interest income on a fully taxable equivalent basis less purchase accounting interest accretion on acquired loans. Net interest margin on a fully taxable equivalent basis is calculated as annualized net interest income on a fully taxable equivalent basis divided by average interest earning assets. Adjusted net interest margin on a fully taxable equivalent basis is calculated as annualized adjusted net interest income on a fully taxable equivalent basis divided by average interest earning assets. These non-GAAP financial measures are calculated on the reconciliation pages that follow). 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 (iv) 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 are intended 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 tables included below and the textual discussion above for a reconciliation of the above described non-GAAP financial measures to their most directly comparable GAAP financial measures.
