NOTE 21 Stock Repurchase Program

On December 12, 2023, the Board of Directors of the Company approved a stock repurchase program (the “Program”) which authorizes the Company to repurchase up to 1,000,000 shares of its common stock subject to certain limitations and conditions. The Program became effective on February 18, 2024, replacing and superseding a prior stock repurchase program, and will expire on February 18, 2027.

The Program does not obligate the Company to repurchase any shares of its common stock, and other than repurchases that have been completed to date, there is no assurance that the Company will do so or that the Company will repurchase shares at favorable prices. The Program may be suspended or terminated at any time and, even if fully implemented, the Program may not enhance long-term stockholder value. For the nine months ended September 30, 2025, the Company did not repurchase any shares under the Program. The Company also repurchases shares to pay withholding taxes on the vesting of restricted stock awards and units.

The entire disclosure for equity.

The adequacy of the ACL on investment securities is assessed at the end of each quarter. The Company does not believe that the AFS debt securities that were in an unrealized loss position as of September 30, 2025 represented a credit loss impairment. As of both September 30, 2025 and December 31, 2024, the gross unrealized loss positions were primarily related to mortgage-backed securities issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss. Additionally, there were corporate bonds in gross unrealized loss positions as of both September 30, 2025 and December 31, 2024; however, all such bonds had an investment grade rating as of both September 30, 2025 and December 31, 2024. Total gross unrealized losses were attributable to changes in interest rates, relative to when the investment securities were purchased, and not due to the credit quality of the investment securities. It is not likely that the Company will be required to sell the investment securities before recovery of their amortized cost basis, which may be at maturity.

The ACL on HTM debt securities is estimated using relevant information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Using a probability of default and loss given default analysis, the ACL on HTM debt securities was $126 thousand and $131 thousand as of September 30, 2025 and December 31, 2024, respectively. The change in the ACL on HTM debt securities was due to a change in the provision for credit losses, with no charge-offs or recoveries for the three and nine months ended September 30, 2025.

Accrued interest receivable on AFS investment securities and HTM investment securities is recorded in accrued interest receivable and is excluded from the estimate of credit losses. As of September 30, 2025, the accrued interest receivable on AFS investment securities and HTM investment securities totaled $1.7 million and $0.9 million, respectively. As of December 31, 2024, the accrued interest receivable on AFS investment securities and HTM investment securities totaled $2.0 million and $1.3 million, respectively.

The Company had no sales of AFS investment securities for the three and nine months ended September 30, 2025 and 2024. The Company had calls of AFS investment securities with proceeds of $0.8 million and $19.8 million for the three and nine months ended September 30, 2025, respectively, and no calls of AFS investment securities for the three and nine months ended September 30, 2024.

The Company had no sales of HTM investment securities for the three and nine months ended September 30, 2025 and 2024.

The following tables present investment securities with gross unrealized losses, for which an ACL was not recorded at September 30, 2025 and December 31, 2024, aggregated by investment category and length of time that individual investment securities have been in a continuous loss position:

As of September 30, 2025 and December 31, 2024, none of the Company’s HTM debt securities were past due or on nonaccrual status. The Company did not recognize any interest income on nonaccrual HTM debt securities during the three months ended September 30, 2025 and 2024.

The following table presents the carrying value and fair value of HTM investment securities and the amortized cost and fair value of AFS investment securities as of September 30, 2025, by contractual maturity:

Expected maturities will differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

Investment securities with a total carrying value of $368.7 million and $340.2 million were pledged as of September 30, 2025 and December 31, 2024, respectively, to secure public deposits and for other purposes required or permitted by law.

As of September 30, 2025 and December 31, 2024, the carrying value of the Company’s Federal Reserve stock and Federal Home Loan Bank of Des Moines (“FHLB”) stock was as follows:

	*September 30,*		*December 31,*
(dollars in thousands)	*2025*		*2024*
Federal Reserve	$	8,631	$	7,519
FHLB		13,020		13,656

These securities can only be redeemed or sold at their par value and only to the respective issuing institution or to another member institution. The Company records these non-marketable equity securities as a component of other assets and periodically evaluates these securities for impairment. Management considers these non-marketable equity securities to be long-term investments. Accordingly, when evaluating these securities for impairment, management considers the ultimate recoverability of the par value rather than recognizing temporary declines in value.

Visa Class B Restricted Shares

In 2008, the Company received Visa Class B restricted shares as part of Visa’s initial public offering. These shares are transferable only under limited circumstances until they can be converted into the publicly traded Class A common shares. This conversion will not occur until the settlement of certain litigation which will be indemnified by Visa members, including the Company. Visa funded an escrow account from its initial public offering to settle these litigation claims. Should this escrow account be insufficient to cover these litigation claims, Visa is entitled to fund additional amounts to the escrow account by reducing each member bank’s Class B conversion ratio to unrestricted Class A shares. As of September 30, 2025, the conversion ratio was 1.5549. Based on the existing transfer restriction and the uncertainty of the outcome of the Visa litigation mentioned above, the 6,924 Class B shares (10,766 Class A equivalents) that the Company owned as of September 30, 2025 and December 31, 2024, were carried at a zero cost basis.

NOTE 12 Commitments and Contingencies

Commitments

In the normal course of business, the Company has outstanding commitments and contingent liabilities, such as commitments to extend credit and standby letters of credit, which are not included in the accompanying consolidated financial statements. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit and standby letters of credit is represented by the contractual or notional amount of those instruments. The Company uses the same credit policies in making such commitments as it does for instruments that are included in the statements of financial condition.

A summary of the contractual amounts of the Company’s exposure to off-balance sheet risk as of September 30, 2025 and December 31, 2024, respectively, was as follows:

	*September 30,*		*December 31,*
(dollars in thousands)	*2025*		*2024*
Commitments to extend credit	$	1,007,983	$	1,090,114
Standby letters of credit		19,418		30,033
Total	$	1,027,400	$	1,120,147

The Company establishes an ACL on unfunded commitments, except those that are unconditionally cancellable by the Company. As of September 30, 2025 and December 31, 2024, the ACL on unfunded commitments was $3.7 million and $7.5 million, respectively. The ACL on unfunded commitments was presented within accrued expenses and other liabilities on the consolidated balance sheets. For the nine months ended September 30, 2025 and 2024, the provision (recovery) for credit losses on unfunded commitments was ($3.9) million and ($31) thousand, respectively.

Commitments to extend credit are agreements to lend to a client as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses, and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each client’s creditworthiness on a case by case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation. Collateral held varies but may include accounts receivable, inventory, property and equipment, and income producing commercial properties.

The Company was not required to perform on any financial guarantees and did not incur any losses on its commitments during the past two years.

The Company utilizes standby letters of credit issued by either the FHLB or the Bank of North Dakota to secure public unit deposits. The Company had letters of credit outstanding with the FHLB in the amount of $8.6 million as of September 30, 2025 and $12.0 million as of December 31, 2024. With the Bank of North Dakota, the Company had no letters of credit outstanding as of September 30, 2025 and had letters of credit outstanding in the amount of $50.0 million as of December 31, 2024. Letters of credit with the Bank of North Dakota were collateralized by loans pledged to the Bank of North Dakota in the amount of $540.3 million and $524.9 million as of September 30, 2025 and December 31, 2024, respectively.

Legal Contingencies

In the normal course of business, including in connection with business combinations pursued by the Company, the Company and its subsidiaries are subject to pending and threatened litigation, claims investigations and legal and administrative cases and proceedings.

Under applicable accounting standards, reserves are established for legal claims only when losses associated with the claims are judged to be probable, and the loss can be reasonably estimated. When a material loss contingency is reasonably possible, but not probable, the Company does not record a liability, but instead discloses the nature of the matter and an estimate of the loss or range of losses, to the extent such estimate can be made. Significant judgment is required in both the determination of possibility or probability, and whether the loss or range of losses is reasonably estimable. The Company’s judgments are subjective and based on the status of the legal or regulatory proceedings, the merits of the Company’s defenses and consultation with in-house and outside legal counsel. Because of uncertainties related to these matters, accruals are based on the best information available to the Company and its advisors at the time, including, among other information, settlement agreements. As additional information becomes available, the Company reassesses the potential liability related to pending claims and litigation and may revise its estimates accordingly. Due to the inherent uncertainties of the legal and regulatory processes, such judgments may be materially different than the actual outcomes. Legal costs such as outside counsel fees are expensed in the period in which the services are rendered.

Assessments of litigation exposure are difficult because they involve inherently unpredictable factors including, but not limited to: whether the proceeding is in the early stages; whether damages are unspecified, unsupported or uncertain; whether there is a potential for punitive or other pecuniary damages; whether the matter involves legal uncertainties, including novel issues of law; whether the matter involves multiple parties and/or jurisdictions; whether discovery has begun or is not complete; whether meaningful settlement discussions have commenced; whether the Company has insurance coverage; and whether the proceeding involves class allegations. In many lawsuits and arbitrations, it is not possible to determine whether a liability will be incurred, or to estimate the ultimate or minimum amount of that liability, until the matter is close to resolution, in which case a reserve will not be recognized until that time. As a result, the Company may be unable to estimate reasonably possible losses with respect to litigation matters it faces.

In 2023, the Company sold its ESOP fiduciary services business but currently remains subject to pending lawsuits related to the sold business, including one brought by the DOL.

In November 2023, the DOL brought suit against several defendants, including the Bank, alleging that the Bank, in its capacity as trustee to an ESOP, (1) breached certain of its fiduciary duties in connection with a transaction which allegedly caused the ESOP to pay more than fair market value to acquire stock, and (2) engaged in a prohibited transaction by causing the ESOP to acquire the stock from an existing company shareholder for more than adequate consideration. The Bank continues to dispute the allegations made by the DOL and intends to continue to defend itself vigorously.

The Company believes a material loss contingency related to the DOL complaint is reasonably possible, but not probable, based on currently-available information. However, the Company is unable to estimate the ultimate or minimum loss or range of losses, if any, at this time due to a number of uncertainties, including, but not limited to: (1) the current early stages of the proceedings and discovery not having commenced, (2) the absence of specificity as to alleged damages, and (3) the lack of resolution of significant factual and legal issues.

The Company did not have any accrued liabilities recorded for loss contingencies that were required to be disclosed as of September 30, 2025 and December 31, 2024, respectively.
