BASIS OF PRESENTATION
BASIS OF PRESENTATION	1. BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements were prepared in accordance with instructions for Quarterly Reports on Form 10-Q and, therefore, do not include all disclosures necessary for a complete presentation of financial condition, results of operations and cash flows in conformity with accounting principles generally accepted in the United States of America (“generally accepted accounting principles” or “GAAP”). However, all adjustments that are, in the opinion of management, necessary for a fair presentation of the interim unaudited consolidated financial statements have been included. All such adjustments are of a normal recurring nature. ​ The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Riverview Bancorp, Inc. Annual Report on Form 10-K for the year ended March 31, 2024 (“2024 Form 10-K”). The unaudited consolidated results of operations for the six months ended September 30, 2024 are not necessarily indicative of the results which may be expected for the entire fiscal year ending March 31, 2025. ​ The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. ​ Certain prior period amounts have been reclassified to conform to the current period presentation; such reclassifications had no effect on previously reported net income or total shareholders’ equity. ​ ​

STOCK PLANS AND STOCK-BASED COMPENSATION
STOCK PLANS AND STOCK-BASED COMPENSATION	3. STOCK PLANS AND STOCK-BASED COMPENSATION Stock Option Plans - In July 2003, shareholders of the Company approved the adoption of the 2003 Stock Option Plan (“2003 Plan”). The 2003 Plan was effective in July 2003 and expired in July 2013. Accordingly, no further option awards may be granted under the 2003 Plan. Further, no options granted under the 2003 plan remain outstanding as of September 30, 2024, with all such awards having been either previously exercised or forfeited. Each option granted under the 2003 Plan had an exercise price equal to the fair value of the Company’s common stock on the date of the grant, a maximum term of ten years and a vesting period from zero to five years . ​ In July 2017, the shareholders of the Company approved the Riverview Bancorp, Inc. 2017 Equity Incentive Plan (“2017 Plan”). The 2017 Plan provides for the grant of incentive stock options, non-qualified stock options, restricted stock and restricted stock units. The Company reserved 1,800,000 shares of its common stock for issuance under the 2017 Plan. At September 30, 2024, there were ­­­­1,546,078 shares available for grant under the 2017 Plan. The 2003 Plan and the 2017 Plan are collectively referred to as “the Stock Option Plans”. ​ The fair value of each stock option granted is estimated on the date of grant using the Black-Scholes stock option valuation model. The fair value of all awards is amortized on a straight-line basis over the requisite service periods, which are generally the vesting periods. The expected life of options granted represents the period of time that they are expected to be outstanding. The expected life is determined based on historical experience with similar options, considering the contractual terms and vesting schedules. Expected volatility is estimated at the date of grant based on the historical volatility of the Company's common stock. Expected dividends are based on dividend trends and the market value of the Company's common stock at the time of grant. The risk-free interest rate for periods within the contractual life of the options is based on the U.S. Treasury yield curve in effect at the time of the grant. There were no stock options granted under the 2017 Stock Option Plan during the six months ended September 30, 2024 and 2023. ​ As of September 30, 2024, all outstanding stock options were fully vested and there was no remaining unrecognized compensation expense related to stock options granted under the Stock Option Plans. There was no stock-based compensation expense related to stock options for the six months ended September 30, 2024 and 2023 under the Stock Option Plans. ​ There was no activity related to stock options for the six months ended September 30, 2024. The following table presents the activity related to stock options under the Stock Option Plans for the six months ended September 30, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Six Months Ended September 30, ​ ​ 2023 ​ ​ Weighted ​ ​ ​ ​ Average ​ ​ ​ Number of ​ Exercise ​ ​ Shares Price Balance, beginning of period 14,310 ​ $ 2.78 Options exercised (12,799) ​ 2.78 Options expired (1,511) ​ 2.78 Balance, end of period — ​ $ — ​ There were no stock options outstanding as of September 30, 2024 and 2023. ​ There was no intrinsic value of stock options exercised for the six months ended September 30, 2024. The total intrinsic value of stock options exercised was $28,000 for the six months ended September 30, 2023, under the Stock Option Plans. ​ The Company may grant restricted stock pursuant to the 2017 Plan of which vesting can either be time based or performance based. Performance based awards are subject to attaining certain performance metrics and all, or a portion of, the performance based awards can subsequently be cancelled for not attaining the predetermined performance metrics. The fair value of restricted stock awards is equal to the fair value of the Company’s stock on the date of grant. The related stock-based compensation expense is recorded over the requisite service period. Stock-based compensation related to restricted stock grants was $26,000 and ($70,000) for the three months ended September 30, 2024 and 2023, respectively. Stock-based compensation related to restricted stock grants was $52,000 and ($8,000) for the six months ended September 30, 2024 and 2023, respectively. The negative amounts for the three and six months ended September 30, 2023 resulted from restricted stock forfeited during the corresponding periods. The unrecognized stock-based compensation related to restricted stock was $119,000 and $ 371,000 at September 30, 2024 and 2023, respectively. The weighted average vesting period for the restricted stock was 0.94 years and 1.79 years at September 30, 2024 and 2023, respectively. ​ A summary of changes in nonvested restricted stock awards for the periods shown: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Time Based Performance Based Total ​ ​ Number ​ Weighted ​ Number ​ Weighted ​ Number ​ Weighted ​ ​ of ​ Average ​ of ​ Average ​ of ​ Average ​ ​ Unvested ​ Grant Date ​ Unvested ​ Grant Date ​ Unvested ​ Grant Date Six Months Ended September 30, 2024 Shares Fair Value Shares Fair Value Shares Fair Value Balance, beginning of period 15,779 ​ $ 5.72 63,397 ​ $ 5.68 79,176 ​ $ 5.69 Forfeited — ​ — (14,075) ​ 5.21 (14,075) ​ 5.21 Vested (6,289) ​ 5.84 (13,417) ​ 6.54 (19,706) ​ 6.32 Balance, end of period 9,490 ​ $ 5.64 35,905 ​ $ 5.54 45,395 ​ $ 5.57 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Time Based Performance Based Total ​ ​ Number ​ Weighted ​ Number ​ Weighted ​ Number ​ Weighted ​ ​ of ​ Average ​ of ​ Average ​ of ​ Average ​ ​ Unvested ​ Grant Date ​ Unvested ​ Grant Date ​ Unvested ​ Grant Date Six Months Ended September 30, 2023 Shares Fair Value Shares Fair Value Shares Fair Value Balance, beginning of period 29,977 ​ $ 6.14 132,645 ​ $ 6.05 162,622 ​ $ 6.07 Granted 19,926 ​ 5.21 84,040 ​ 5.21 103,966 ​ 5.21 Forfeited (15,726) ​ 5.85 (87,948) ​ 5.97 (103,674) ​ 5.95 Vested (14,126) ​ 5.64 (50,798) ​ 5.26 (64,924) ​ 5.34 Balance, end of period 20,051 ​ $ 5.80 77,939 ​ $ 5.75 97,990 ​ $ 5.77 ​

EARNINGS PER SHARE	4. EARNINGS PER SHARE Basic earnings per share (“EPS”) is computed by dividing net income or loss applicable to common stock by the weighted average number of common shares outstanding during the period, without considering any dilutive items. Nonvested shares of restricted stock are included in the computation of basic EPS because the holder has voting rights and shares in non-forfeitable dividends during the vesting period. Diluted EPS is computed by dividing net income applicable to common stock by the weighted average number of common shares and common stock equivalents for items that are dilutive, net of shares assumed to be repurchased using the treasury stock method at the average share price for the Company’s common stock during the period. Common stock equivalents arise from the assumed exercise of outstanding stock options. For the six months ended September 30, 2024 and 2023, there were no stock options excluded in computing diluted EPS. ​ In November 2022, the Company’s Board of Directors adopted a stock repurchase program (the “November 2022 repurchase program”). Under the November 2022 repurchase program, the Company was authorized to repurchase up to $2.5 million of the Company’s outstanding shares of common stock, in the open market, based on prevailing market prices, or in privately negotiated transactions, over a period beginning on November 28, 2022 and continuing until the earlier of the completion of the authorized level of repurchases or May 28, 2023, depending upon market conditions. The Company completed the November 2022 repurchase program on May 5, 2023, repurchasing a total of 394,334 shares at an average cost of $6.34 per share for a total cost of $2.5 million. All shares repurchased under the November 2022 program were settled. On September 26, 2024, the Company’s Board of Directors announced the adoption of a stock repurchase program authorizing the Company to repurchase up to $2.0 million of the Company’s outstanding shares of common stock, in the open market, based on prevailing market prices, or in privately negotiated transactions. The repurchase program became effective on October 30, 2024 and will continue until the earlier of the completion of the repurchase or 12 months after the effective date, depending upon market conditions.

If the Company intends to sell the security or it is more likely than not that the Company will be required to sell the security before recovering its cost basis, the entire impairment loss would be recognized in earnings. If the Company does not intend to sell the security and it is not more likely than not that the Company will be required to sell the security, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, Management considers the extent to which fair value is less than amortized costs, any changes to the rating of the security by a rating agency and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. Projected cash flows are discounted by the current effective interest rate. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. The remaining impairment related to all other factors, the difference between the present value of the cash flows expected to be collected and fair value, is recognized as a charge to accumulated other comprehensive income (loss) (“AOCI”). ACL on Held to Maturity Debt Securities – The Company had no sales and realized no gains or losses on sales of investment securities for the six months ended September 30, 2024 and 2023. Investment securities available for sale with an amortized cost of $2.4 million and $2.6 million and an estimated fair value of $2.2 million and $2.4 million at September 30, 2024 and March 31, 2024, respectively, were pledged as collateral for government public funds held by the Bank. Investment securities held to maturity with an amortized cost of $10.7 million and $11.2 million and a fair value of $9.2 million and $9.3 million at September 30, 2024 and March 31, 2024, respectively, were pledged as collateral for government public funds held by the Bank. Investment securities held to maturity with an amortized cost of $145.9 million and $151.2 million and a fair value of $126.4 million and $126.1 million at September 30, 2024 and March 31, 2024, respectively, were pledged as collateral to the Federal Reserve Bank of San Francisco (“FRB”) pursuant to borrowing agreements.

allowance for credit losses. The existence of some or all of the following criteria will generally confirm that a loss has been incurred: the loan is significantly delinquent and the borrower has not demonstrated the ability or intent to bring the loan current; the Company has no recourse to the borrower, or if it does, the borrower has insufficient assets to pay the debt; and/or the estimated fair value of the loan collateral is significantly below the current loan balance, and there is little or no near-term prospect for improvement. ​ Management’s evaluation of the ACL for loans is based on ongoing, quarterly assessments of the known and inherent risks in the loan portfolio. Loss factors are based on the Company’s historical loss experience with additional consideration and adjustments made for changes in economic conditions, changes in the amount and composition of the loan portfolio, delinquency rates, changes in collateral values, seasoning of the loan portfolio, duration of the current business cycle, a detailed analysis of individually evaluated loans and other factors as deemed appropriate. These factors are evaluated on a quarterly basis. Loss rates used by the Company are affected as changes in these factors increase or decrease from quarter to quarter. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s ACL for loans and may require the Company to make additions to the ACL for loans based on their judgment about information available to them at the time of their examinations. ​ The following tables detail activity in the ACL for loans at or for the three and six months ended September 30, 2024 and September 30, 2023, by loan category (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended Commercial Commercial ​ ​ Multi- Real Estate ​ ​ ​ ​ ​ ​ September 30, 2024 ​ Business ​ Real Estate ​ Land ​ Family ​ Construction ​ Consumer ​ Unallocated ​ Total ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Beginning balance ​ $ 5,141 ​ $ 7,303 ​ $ 120 ​ $ 402 ​ $ 723 ​ $ 1,675 ​ $ — ​ $ 15,364 (Recapture of) provision for credit losses ​ (23) ​ ​ (166) ​ ​ 19 ​ ​ (48) ​ ​ 202 ​ ​ 116 ​ ​ — ​ ​ 100 Charge-offs ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — Recoveries ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ 2 ​ ​ — ​ ​ 2 Ending balance ​ $ 5,118 ​ $ 7,137 ​ $ 139 ​ $ 354 ​ $ 925 ​ $ 1,793 ​ $ — ​ $ 15,466 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Six months ended ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Beginning balance ​ $ 5,280 ​ $ 7,391 ​ $ 106 ​ $ 367 ​ $ 636 ​ $ 1,584 ​ $ — ​ $ 15,364 Provision for (recapture of) credit losses ​ (162) ​ ​ (254) ​ ​ 33 ​ ​ (13) ​ ​ 289 ​ ​ 207 ​ ​ — ​ 100 Charge-offs ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ (1) ​ ​ — ​ (1) Recoveries ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ 3 ​ ​ — ​ 3 Ending balance ​ $ 5,118 ​ $ 7,137 ​ $ 139 ​ $ 354 ​ $ 925 ​ $ 1,793 ​ $ — ​ $ 15,466 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2023 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Beginning balance ​ $ 5,215 ​ $ 7,205 ​ $ 123 ​ $ 293 ​ $ 830 ​ $ 1,677 ​ $ — ​ $ 15,343 Provision for (recapture of) credit losses ​ 124 ​ ​ (67) ​ ​ (11) ​ ​ — ​ ​ 30 ​ ​ (76) ​ ​ — ​ ​ — Charge-offs ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — Recoveries ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ 3 ​ ​ — ​ ​ 3 Ending balance ​ $ 5,339 ​ $ 7,138 ​ $ 112 ​ $ 293 ​ $ 860 ​ $ 1,604 ​ $ — ​ $ 15,346 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Six months ended ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2023 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Beginning balance ​ $ 3,123 ​ $ 8,894 ​ $ 93 ​ $ 798 ​ $ 764 ​ $ 1,127 ​ $ 510 ​ $ 15,309 Impact of adopting CECL (ASU 2016-13) ​ ​ 1,884 ​ ​ (1,494) ​ ​ 40 ​ ​ (492) ​ ​ 131 ​ ​ 483 ​ ​ (510) ​ ​ 42 Provision for (recapture of) loan losses ​ 332 ​ (262) ​ (21) ​ (13) ​ (35) ​ (1) ​ — ​ — Charge-offs ​ — ​ — ​ — ​ — ​ — ​ (11) ​ — ​ (11) Recoveries ​ — ​ — ​ — ​ — ​ — ​ 6 ​ — ​ 6 Ending balance ​ $ 5,339 ​ $ 7,138 ​ $ 112 ​ $ 293 ​ $ 860 ​ $ 1,604 ​ $ — ​ $ 15,346 ​ ​ Non-accrual loans ​ The following tables present an analysis of loans by aging category at the dates indicated (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total ​ ​ ​ ​ ​ ​ ​ ​ ​ 90 Days ​ ​ ​ ​ Past ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ and ​ ​ ​ ​ Due and ​ ​ ​ ​ Total ​ ​ 30-89 Days ​ Greater ​ ​ ​ ​ Non- ​ ​ ​ ​ Loans September 30, 2024 ​ Past Due ​ Past Due ​ Non-accrual ​ accrual ​ Current ​ Receivable ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial business ​ $ 3,063 ​ $ 301 ​ $ 48 ​ $ 3,412 ​ $ 233,483 ​ $ 236,895 Commercial real estate ​ 3,745 ​ — ​ 68 ​ ​ 3,813 ​ ​ 569,642 ​ ​ 573,455 Land ​ — ​ — ​ — ​ ​ — ​ ​ 7,274 ​ ​ 7,274 Multi-family ​ — ​ — ​ — ​ ​ — ​ ​ 78,710 ​ ​ 78,710 Real estate construction ​ — ​ — ​ — ​ ​ — ​ ​ 51,498 ​ ​ 51,498 Consumer ​ 36 ​ — ​ 33 ​ ​ 69 ​ ​ 113,076 ​ ​ 113,145 Total ​ $ 6,844 ​ $ 301 ​ $ 149 ​ $ 7,294 ​ $ 1,053,683 ​ $ 1,060,977 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial business ​ $ 1,778 ​ $ 5 ​ $ 58 ​ $ 1,841 ​ $ 227,563 ​ $ 229,404 Commercial real estate ​ — ​ — ​ 79 ​ ​ 79 ​ ​ 583,422 ​ ​ 583,501 Land ​ — ​ — ​ — ​ ​ — ​ ​ 5,693 ​ ​ 5,693 Multi-family ​ — ​ — ​ — ​ ​ — ​ ​ 70,771 ​ ​ 70,771 Real estate construction ​ — ​ — ​ — ​ ​ — ​ ​ 36,538 ​ ​ 36,538 Consumer ​ 1 ​ — ​ 36 ​ ​ 37 ​ ​ 98,069 ​ ​ 98,106 Total ​ $ 1,779 ​ $ 5 ​ $ 173 ​ $ 1,957 ​ $ 1,022,056 ​ $ 1,024,013 ​ The increase in the 30-89 days past due loans was primarily related to one loan that is in the probate process.

GOODWILL
GOODWILL	7. GOODWILL Goodwill and certain other intangibles generally arise from business combinations accounted for under the purchase method of accounting. Goodwill and other intangibles deemed to have indefinite lives generated from business combinations are not subject to amortization and are instead tested for impairment not less than annually. The Company has two reporting units, the Bank and the Trust Company, for purposes of evaluating goodwill for impairment. All the Company’s goodwill has been allocated to the Bank reporting unit. The Company performed an impairment assessment as of October 31, 2023 and determined that no impairment of goodwill exists. The goodwill impairment test involves a two-step process. The first step is a comparison of the reporting unit’s fair value to its carrying value. If the reporting unit’s fair value is less than its carrying value, the Company would be required to progress to the second step. In the second step, the Company calculates the implied fair value of goodwill and compares the implied fair value of goodwill to the carrying amount of goodwill in the Company’s consolidated balance sheet. If the carrying amount of the goodwill is greater than the implied fair value of that goodwill, an impairment loss must be recognized in an amount equal to that excess. The implied fair value of goodwill is determined in the same manner as goodwill recognized in a business combination. The results of the Company’s step one test indicated that the reporting unit’s fair value was greater than its carrying value, and, therefore, a step two analysis was not required; however, no assurance can be given that the Company’s goodwill will not be written down in future periods. The Company completed a qualitative assessment of goodwill as of September 30, 2024, and concluded that it is more likely than not that the fair value of the Bank (the reporting unit), exceeds its carrying value at that date.

JUNIOR SUBORDINATED DEBENTURES
JUNIOR SUBORDINATED DEBENTURES	9. JUNIOR SUBORDINATED DEBENTURES The Company has wholly-owned subsidiary grantor trusts that were established for the purpose of issuing trust preferred securities and common securities. The trust preferred securities accrue and pay distributions periodically at specified annual rates as provided in each trust agreement. The trusts used the net proceeds from each of the offerings to purchase a like amount of junior subordinated debentures (the “Debentures”) of the Company. The Debentures are the sole assets of the trusts. The Company’s obligations under the Debentures and related documents, taken together, constitute a full and unconditional guarantee by the Company of the obligations of the trusts. The trust preferred securities are mandatorily redeemable upon maturity of the Debentures or upon earlier redemption as provided in the indentures. The Company has the right to redeem the Debentures in whole or in part on or after specific dates, at a redemption price specified in the indentures governing the Debentures plus any accrued but unpaid interest to the redemption date. The Company also has the right to defer the payment of interest on each of the Debentures for a period not to exceed 20 consecutive quarters, provided that the deferral period does not extend beyond the stated maturity. During such deferral period, distributions on the corresponding trust preferred securities will also be deferred and the Company may not pay cash dividends to the holders of shares of the Company’s common stock. ​ ​ The Debentures issued by the Company to the grantor trusts, which totaled $27.0 million at both September 30, 2024 and March 31, 2024, are reported as “junior subordinated debentures” in the consolidated balance sheets. The common securities issued by the grantor trusts were purchased by the Company, and the Company’s investment in the common securities of $836,000 at both September 30, 2024 and March 31, 2024, is included in prepaid expenses and other assets in the consolidated balance sheets. The Company records interest expense on the Debentures in the consolidated statements of income. The following table is a summary of the terms and the amounts outstanding of the Debentures at September 30, 2024 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Issuance Trust Issuance Date Amount Outstanding Rate Type Initial Rate Current Rate Maturity Date ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Riverview Bancorp Statutory Trust I 12/2005 ​ $ 7,217 Variable (1) 5.88 % 6.57 % 3/2036 Riverview Bancorp Statutory Trust II 06/2007 ​ 15,464 Variable (2) 7.03 % 6.56 % 9/2037 Merchants Bancorp Statutory Trust I (4) 06/2003 ​ 5,155 Variable (3) 4.16 % 8.02 % 6/2033 ​ ​ ​ ​ 27,836 ​ ​ ​ ​ ​ ​ ​ ​ Fair value adjustment (4) ​ ​ ​ (788) Total Debentures ​ ​ ​ $ 27,048 ​ (1) The trust preferred securities reprice quarterly based on the three-month Chicago Mercantile Exchange (“CME”) Term SOFR plus 1.36% .

FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS	10. FAIR VALUE MEASUREMENTS Fair value is defined under GAAP as the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. GAAP requires that valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs. GAAP also establishes a fair value hierarchy which prioritizes the valuation inputs into three broad levels. Based on the underlying inputs, each fair value measurement in its entirety is reported in one of three levels. These levels are: Quoted prices in active markets for identical assets (Level 1) Other observable inputs (Level 2) Significant unobservable inputs (Level 3) Financial instruments are presented in the tables that follow by recurring or nonrecurring measurement status. Recurring assets are initially measured at fair value and are required to be remeasured at fair value in the consolidated financial statements at each reporting date. Assets measured on a nonrecurring basis are assets that, as a result of an event or circumstance, were required to be remeasured at fair value after initial recognition in the consolidated financial statements at some time during the reporting period. The following tables present assets that are measured at estimated fair value on a recurring basis at the dates indicated (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Estimated ​ Estimated Fair Value Measurements Using September 30, 2024 Fair Value Level 1 Level 2 Level 3 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Investment securities available for sale: ​ ​ ​ ​ Municipal securities ​ $ 31,892 ​ $ — ​ $ 31,892 ​ $ — Agency securities ​ 38,981 ​ — ​ 38,981 ​ — Real estate mortgage investment conduits ​ 25,044 ​ — ​ 25,044 ​ — Residential mortgage-backed securities ​ 11,534 ​ — ​ 11,534 ​ — Other mortgage-backed securities ​ 25,502 ​ — ​ 25,502 ​ — Total assets measured at fair value on a recurring basis ​ $ 132,953 ​ $ — ​ $ 132,953 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Estimated Estimated Fair Value Measurements Using March 31, 2024 Fair Value Level 1 Level 2 Level 3 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Investment securities available for sale: ​ ​ ​ ​ Municipal securities ​ $ 35,136 ​ $ — ​ $ 35,136 ​ $ — Agency securities ​ 43,577 ​ — ​ 43,577 ​ — Real estate mortgage investment conduits ​ 25,665 ​ — ​ 25,665 ​ — Residential mortgage-backed securities ​ 12,551 ​ — ​ 12,551 ​ — Other mortgage-backed securities ​ 26,267 ​ — ​ 26,267 ​ — Total assets measured at fair value on a recurring basis ​ $ 143,196 ​ $ — ​ $ 143,196 ​ $ — ​ There were no transfers of assets into or out of Levels 1, 2 or 3 for both the six months ended September 30, 2024 and the year ended March 31, 2024. The following methods were used to estimate the fair value of financial instruments above: Investment securities are included within Level 1 of the hierarchy when quoted prices in an active market for identical assets are available. The Company uses a third-party pricing service to assist the Company in determining the fair value of its Level 2 securities, which incorporates pricing models and/or quoted prices of investment securities with similar characteristics. Investment securities are included within Level 3 of the hierarchy when there are significant unobservable inputs. For Level 2 securities, the independent pricing service provides pricing information by utilizing evaluated pricing models supported with market data information. Standard inputs include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data from market research publications. The Company’s third-party pricing service has established processes for the Company to submit inquiries regarding the estimated fair value. In such cases, the Company’s third-party pricing service will review the inputs to the evaluation in light of any new market data presented by the Company. The Company’s third-party pricing service may then affirm the original estimated fair value or may update the evaluation on a go-forward basis. Management reviews the pricing information received from the third-party pricing service through a combination of procedures that include an evaluation of methodologies used by the pricing service, analytical reviews and performance analysis of the prices against statistics and trends. Based on this review, management determines whether the current placement of the security in the fair value hierarchy is appropriate or whether transfers may be warranted. As necessary, management compares prices received from the pricing service to discounted cash flow models or by performing independent valuations of inputs and assumptions similar to those used by the pricing service in order to help ensure prices represent a reasonable estimate of fair value. There were no assets measured at estimated fair value on a nonrecurring basis at both September 30, 2024 and March 31, 2024. The following disclosure of the estimated fair value of financial instruments is made in accordance with GAAP. The Company, using available market information and appropriate valuation methodologies, has determined the estimated fair value amounts. However, considerable judgment is necessary to interpret market data in the development of the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize in the future. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

NEW ACCOUNTING PRONOUNCEMENTS	11. NEW ACCOUNTING PRONOUNCEMENTS In December 2023, the Financial Accounting Standards Board (“FASB”) issued guidance within Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures Those amendments require disclosure of the following information about income taxes paid on an annual basis: ● Income taxes paid (net of refunds received), disaggregated by federal and state taxes and by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than five percent of total income taxes paid (net of refunds received). ● Income tax expense (or benefit) from continuing operations disaggregated by federal and state jurisdictions. The ASU is effective for annual periods beginning after December 15, 2024. The amendments should be applied on a prospective basis. The Company expects this ASU to only impact its disclosure requirements and does not expect the adoption of this ASU to have a material impact on its business operations or financial condition.

REVENUE FROM CONTRACTS WITH CUSTOMERS
REVENUE FROM CONTRACTS WITH CUSTOMERS	12. REVENUE FROM CONTRACTS WITH CUSTOMERS In accordance with ASC Topic 606 “Revenues from Contracts with Customers” (“ASC 606”), revenues are recognized when goods or services are transferred to the customer in exchange for the consideration the Company expects to be entitled to receive. The largest portion of the Company’s revenue is from interest income, which is not within the scope of ASC 606. All of the Company’s revenue from contracts with customers within the scope of ASC 606 is recognized in non-interest income except for gains on sales of REO and premises and equipment, which are included in non-interest expense. If a contract is determined to be within the scope of ASC 606, the Company recognizes revenue as it satisfies a performance obligation. Payments from customers are generally collected at the time services are rendered, monthly, or quarterly. For contracts with customers within the scope of ASC 606, revenue is either earned at a point in time or revenue is earned over time. Examples of revenue earned at a point in time are automated teller machine (“ATM”) transaction fees, wire transfer fees, overdraft fees and interchange fees. Revenue earned at a point in time is primarily based on the number and type of transactions that are generally derived from transactional information accumulated by the Company’s systems and is recognized immediately as the transactions occur or upon providing the service to complete the customer’s transaction. The Company is generally the principal in these contracts, except for interchange fees, in which case the Company is acting as the agent and records revenue net of expenses paid to the principal. Examples of revenue earned over time, which generally occur monthly, are deposit account maintenance fees, investment advisory fees, merchant revenue, trust and investment management fees and safe deposit box fees. Revenue is generally derived from transactional information accumulated by the Company’s systems or those of third-parties and is recognized as the related transactions occur or services are rendered to the customer. For the six months ended September 30, 2024 and 2023, substantially all of the Company’s revenues within the scope of ASC 606 are for performance obligations satisfied at a point in time.

In addition, the Company had no material unsatisfied performance obligations as of September 30, 2024 and 2023.

COMMITMENTS AND CONTINGENCIES
COMMITMENTS AND CONTINGENCIES	13. COMMITMENTS AND CONTINGENCIES Off-balance sheet arrangements Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third-party. These guarantees are primarily used to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Collateral held varies and is required in instances where the Company deems it necessary. Significant off-balance sheet commitments at September 30, 2024 are listed below (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Contract or Notional ​ ​ Amount ​ ​ September 30, ​ 2024 Commitments to extend credit: ​ Adjustable-rate ​ $ 14,818 Fixed-rate ​ — Standby letters of credit ​ 1,600 Undisbursed loan funds and unused lines of credit ​ 112,389 Total ​ $ 128,807 ​ Other contractual obligations – The Bank is a public depository and, accordingly, accepts deposit and other public funds belonging to, or held for the benefit of, Washington and Oregon states, political subdivisions thereof, and municipal corporations. In accordance with applicable state law, in the event of default of a participating bank, all other participating banks in the state collectively assure that no loss of funds are suffered by any public depositor. Generally, in the event of default by a public depository, the assessment attributable to all public depositories is allocated on a pro rata basis in proportion to the maximum liability of each depository as it existed on the date of loss. The Company did not incur any losses related to public depository funds for the six months ended September 30, 2024 and 2023. The Bank has entered into employment contracts with certain key employees, which provide for contingent payments subject to future events. Litigation The Company was involved in litigation with a former business client concerning real estate investments offered by a business owned by that client. In May 2023, the parties participated in mediation, after which a stay of proceedings was issued to facilitate continued settlement discussions. As of March 31, 2024, based on available information, including the likelihood of a proposed global settlement, management determined that a loss was probable and could be reasonably estimated. Consequently, the Company recorded a $2.3 million expense in other non-interest expense for the three months ended March 31, 2024. This amount reflected the Company’s estimate of litigation costs exceeding its insurance coverage. The settlement was subsequently approved by all relevant courts in July 2024 and the final settlement payment of $2.3 million was made in August 2024, fully releasing the Company from all claims related to the litigation. In September 2024, the Company received approximately $600,000 in legal expense recovery related to the settled litigation matter of which approximately $500,000 was recorded in non-interest income and $100,000 was recorded as a recovery of legal expenses through the line item of professional fees in non-interest expense.

LEASES
LEASES	14. LEASES The Company has a finance lease for the shell of the building constructed as the Company’s operations center which expires in November 2039. The Company is also obligated under various noncancelable operating lease agreements for land, buildings and equipment that require future minimum rental payments. For each operating lease with an initial term of more than 12 months, the Company records an operating lease right-of-use (“ROU”) asset (representing the right to use the underlying asset for the lease term) and an operating lease liability (representing the obligation to make lease payments required under the terms of the lease). Operating lease ROU assets and operating lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Company uses its estimated incremental borrowing rate – derived from information available at the lease commencement date – as the discount rate when determining the present value of lease payments. The Company does not have any operating leases with an initial term of 12 months or less. Certain operating leases contain various provisions for increases in rental rates, based either on changes in the published Consumer Price Index or a predetermined escalation schedule. Certain operating leases provide the Company with the option to extend the lease term one or more times following expiration of the initial term. Lease extensions are not reasonably certain and the Company generally does not include payments occurring during option periods in the calculation of its operating lease ROU assets and operating lease liabilities.

BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements were prepared in accordance with instructions for Quarterly Reports on Form 10-Q and, therefore, do not include all disclosures necessary for a complete presentation of financial condition, results of operations and cash flows in conformity with accounting principles generally accepted in the United States of America (“generally accepted accounting principles” or “GAAP”). However, all adjustments that are, in the opinion of management, necessary for a fair presentation of the interim unaudited consolidated financial statements have been included. All such adjustments are of a normal recurring nature. ​ The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Riverview Bancorp, Inc. Annual Report on Form 10-K for the year ended March 31, 2024 (“2024 Form 10-K”). The unaudited consolidated results of operations for the six months ended September 30, 2024 are not necessarily indicative of the results which may be expected for the entire fiscal year ending March 31, 2025. ​ The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. ​ Certain prior period amounts have been reclassified to conform to the current period presentation; such reclassifications had no effect on previously reported net income or total shareholders’ equity.
Principles of Consolidation	The accompanying consolidated financial statements include the accounts of Riverview Bancorp, Inc.; its wholly-owned subsidiary, Riverview Bank (the “Bank”); and the Bank’s wholly-owned subsidiaries, Riverview Services, Inc. and Riverview Trust Company (the “Trust Company”) (collectively referred to as the “Company”). All inter-company transactions and balances have been eliminated in consolidation. ​
