Adoption of New Accounting Stan

Adoption of New Accounting Standards
Adoption of New Accounting Standards	Note 2— Adoption of New Accounting Standards In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2022-02, Financial Instruments – Credit Losses ( Topic 326): Troubled Debt Restructurings and Vintage Disclosures Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued ASU 2016-13 (and subsequent amendments), which significantly changes estimates for credit losses related to financial assets measured at amortized cost, including loan receivables and other contracts, such as off-balance sheet credit exposure, specifically, loan commitments and standby letters of credit, financial guarantees, and other similar instruments. The guidance replaced the current incurred loss accounting model with an expected loss model, which is referred to as the current expected credit loss (“CECL”) model. The CECL model requires the measurement of the lifetime expected credit losses on financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Additionally, ASU 2016-13 requires credit losses on available for sale debt securities to be presented as an allowance rather than as a write-down. The guidance requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an entity’s portfolio. The Company adopted ASU 2016-13 on January 1, 2023 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. Results for reporting periods beginning after January 1, 2023 are presented under ASC 326 while amounts for prior periods continue to be reported in accordance with previously applicable accounting principles generally accepted in the United States of America (“U.S. GAAP”). The Company recorded a cumulative effect adjustment of $778, net of tax, to increase the opening balance of retained earnings as of January 1, 2023, for the initial application of CECL. Upon adoption, the allowance for credit losses for loans decreased by $1,651 primarily driven by the allowance for credit losses on the construction loan portfolio due to the short contractual maturities of the loans in this portfolio segment (all construction loans mature in 2023). This was partially offset by an increase in the allowance for credit losses in both our residential real estate and commercial real estate portfolio segments which have longer contractual maturities. In addition, the Company established a liability for unfunded commitments of $ The details of the changes and quantitative impact on the financial statement line items in the condensed consolidated balance sheet as of January 1, 2023 for the adoption of ASU 2016-13, along with the adoption of ASU 2022-02, were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Prior to Adjustments for Adjustments for After ​ ​ Adoption ​ ASU 2016-13 ​ ASU 2022-02 Adoption Assets: ​ ​ ​ ​ ​ ​ Allowance for credit losses – loans ​ $ 45,464 ​ $ (1,651) ​ $ 380 ​ $ 44,193 Liabilities: ​ ​ ​ ​ ​ ​ Liability for unfunded commitments ​ — ​ 579 ​ — ​ ​ 579 Pretax cumulative effect adjustment of a change in accounting principle ​ — ​ (1,072) ​ 380 ​ ​ — Less: income taxes ​ — ​ 294 ​ (104) ​ ​ — Cumulative effect adjustment of a change in accounting principle, net of tax ​ — ​ $ (778) ​ $ 276 ​ ​ — ​ The loan portfolio is pooled into segments with similar characteristics and risk profiles for which the probability of default/loss given default methodology is then applied. The Company utilizes a 24-month economic forecast. For all classes of financial assets deemed collateral dependent, the Company elected the practical expedient to estimate the expected credit losses based on the respective collateral’s fair value less cost to sell. ​ The Company also made an accounting policy election to not measure an allowance for credit losses on accrued interest receivable and to present accrued interest receivable separately from the related financial asset on the condensed consolidated balance sheet. The Company’s available for sale debt securities are comprised of debt, mortgage-backed securities and collateralized mortgage obligations. The debt, mortgage-backed securities and the majority of the collateralized mortgage obligations are issued by the U.S. government, its agencies and government-sponsored enterprises. Management has concluded that the long history with no credit losses from these issuers indicates an expectation that nonpayment of the amortized cost is zero. Thus, the Company has not recorded an allowance for credit losses for its available for sale debt securities at the date of adoption. As stated, the comparative prior period information presented before January 1, 2023 has not been adjusted and continues to be reported under the Company’s historical allowance for loan losses policies as described in Note 2 to the consolidated financial statements in the 2022 Form 10-K.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 3— Summary of Significant Accounting Policies Principles of Consolidation The accompanying condensed consolidated financial statements have been prepared in conformity with U.S. GAAP. The condensed consolidated financial statements include the results of Sterling Bancorp, Inc. and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Due to the inherent uncertainty involved in making estimates, actual results reported in the future periods may be based upon amounts that could differ from those estimates. Concentration of Credit Risk The loan portfolio consists primarily of residential real estate loans, which are collateralized by real estate. At March 31, 2023 and December 31, 2022, residential real estate loans accounted for 83% and 84%, respectively, of total gross loans. In addition, most of these residential loans and other commercial loans have been made to individuals and businesses in the state of California, which are dependent on the area economy for their livelihoods and servicing of their loan obligation. At March 31, 2023 and December 31, 2022, approximately 81% of gross loans were originated with respect to properties or businesses located in the state of California. In December 2019, the Company terminated a loan product consisting of one-, three-, five- or seven-year adjustable-rate mortgages that required a down payment of at least 35% (also referred to herein as “Advantage Loan Program loans”) which continues to be the largest portion of gross residential loans. An internal review of the Advantage Loan Program indicated that certain employees engaged in misconduct in connection with the origination of a significant number of such loans, including with respect to verification of income, the amount of income reported for borrowers, reliance on third parties and related documentation. Refer to Note 15—Commitments and Contingencies. Advantage Loan Program loans (including residential real estate loans held for sale of $36,234 and $6,181 at March 31, 2023 and December 31, 2022, of which $26,074 and $1,942 were on nonaccrual status as of those respective dates) totaled $824,033 and $880,373, or 62% and 63% of gross residential loans, at March 31, 2023 and December 31, 2022, respectively. Investment Securities Debt Securities (Effective January 1, 2023) ​ Debt securities are classified as either available for sale or held to maturity. Management determines the classification of the debt securities when they are purchased. All debt securities were categorized as available for sale as of March 31, 2023 and December 31, 2022. Debt securities available for sale are stated at fair value, with unrealized gains and losses reported in accumulated other comprehensive loss, net of income taxes. The amortized cost of debt securities is adjusted for amortization of premiums (noncallable) and accretion of discounts. The Company amortizes premiums and accretes discounts using the effective interest method over the contractual life of the individual securities or, in the case of asset-backed securities, using the effective yield method over the estimated life of the individual securities. Interest income includes amortization or accretion of purchase premium or discount. Gains and losses realized on the sales of available for sale debt securities are recorded on the settlement date and determined using the specific identification method. For available for sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For available for sale debt securities that do not meet the aforementioned criteria, the Company evaluates at the individual security level 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 cost, 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. 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. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income, net of income taxes. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit losses. Losses are charged against the allowance for credit losses when management believes the uncollectibility of an available for sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on available for sale debt securities is recorded separately from the amortized cost basis of the debt securities in the condensed consolidated balance sheets and is excluded from the estimate of credit losses. ​ Equity Securities Equity securities with readily determinable fair values are stated at fair value with unrealized and realized gains and losses reported in income. Those equity securities without readily determinable fair values are recorded at cost less any impairments, adjusted for subsequent observable price changes in orderly transactions for an identical or similar investment of the same issuer. Any changes in the carrying value of the equity investments are recognized in income. Management performs a qualitative assessment each reporting period to identify impairment of equity securities without readily determinable fair values. When a qualitative assessment indicates that an impairment exists, management determines the fair value of the investment and if the fair value is less than the investment’s carrying value, an impairment charge is recorded in income equal to the difference between the fair value and the carrying amount of the investment. ​ Loans Held for Sale The Company originates certain loans intended for sale in the secondary market. Loans held for sale are carried at the lower of amortized cost or fair value on an individual loan basis. The fair value of loans held for sale are primarily determined based on quoted prices for similar loans in active markets or outstanding commitments from third-party investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to non-interest income in the condensed consolidated statements of operations. Performing residential real estate loans that are held for sale are generally sold with servicing rights retained. The carrying value of mortgage loans sold is reduced by the amount allocated to the servicing right. On the sale of an originated loan, the servicing right is recorded at its estimated fair value. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold and are recorded as a component of non-interest income. Loans that are originated and classified as held for investment are periodically sold in order to manage liquidity, asset credit quality, interest rate risk or concentration risk. Loans that are reclassified into loans held for sale from loans held for investment, due to a change in intent, are recorded at the lower of cost or fair value. Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at amortized cost, net of the allowance for credit losses. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts, and deferred loan fees and costs. Accrued interest receivable related to loans is recorded separately from the amortized cost basis of loans on the condensed consolidated balance sheets and is excluded from the estimate of credit losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct loan origination costs, are deferred and amortized over the contractual lives of the respective loans as a yield adjustment using the effective interest method. Other credit-related fees are recognized as fee income, as a component of non-interest income. Interest income on loans is accrued as earned using the interest method over the term of the loan. The accrual of interest income is discontinued at the time the loan is 90 days past due or earlier if conditions warrant and placed on nonaccrual status. In all cases, loans are placed on nonaccrual status at an earlier date if collection of principal or interest is considered doubtful. All interest accrued and not received for loans placed on nonaccrual status is reversed against interest income. Any payments received on nonaccrual loans are applied to interest income on a cash basis if the loan is considered well secured. Otherwise, all payments received are applied first to outstanding loan principal amounts and then to the recovery of the charged off loan amounts. Any excess is treated as a recovery of interest and fees. Loans are returned to accrual status after all principal and interest amounts contractually due are made and future payments are reasonably assured. ​ Allowance for Credit Losses - Loans (Effective January 1, 2023) The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of held for investment loans to present the net amount expected to be collected on the loans. The allowance for credit losses is adjusted through a charge (recovery) to provision for (recovery of) credit losses in the condensed consolidated statements of operations. When the Company determines that all or a portion of a loan is uncollectible, the appropriate amount is written off, and the allowance for credit losses is reduced by the same amount. The Company applies judgment to determine when a loan is deemed uncollectible; however, generally a loan will be considered uncollectible no later than when all efforts at collection have been exhausted. Subsequent recoveries, if any, are credited to the allowance for credit losses when received. Portions of the allowance for credit losses may be allocated for specific credits; however, the entire allowance for credit losses is available for any credit that, in management’s judgment, should be charged off. The Company estimates the allowance for credit losses on loans based on the underlying loans’ amortized cost. If the collection of principal becomes uncertain, the Company stops accruing interest and reverses the accrued but unpaid interest against interest income. The Company has made a policy election to exclude accrued interest receivable from the measurement of the allowance for credit losses. The allowance for credit losses process involves procedures to appropriately consider the unique characteristics of the Company’s portfolio segments. The allowance for credit losses is measured on a collective (pool) basis for portfolios of loans with similar risk characteristics and risk profiles. The Company’s portfolio segments include the following: (i) commercial real estate, (ii) commercial construction, (iii) commercial and industrial, (iv) residential real estate and (v) home equity lines of credit. These portfolio segments were identified based on their common characteristics: loan type/purpose of loan, underlying collateral type, historical/expected credit loss patterns, availability of credit quality indicators (i.e., FICO, risk rating, delinquency) and completeness of the historical information. Loans which do not share risk characteristics The amount of the allowance for credit losses represents management’s best estimate of current expected credit losses on loans considering available information from internal and external sources, which is relevant to assessing collectability of the loans over the loans’ contractual terms, adjusted for expected prepayments. The contractual term excludes expected extensions, renewals and modifications unless: (i) management has a reasonable expectation at the reporting date that an individual borrower is experiencing financial difficulty and a modification of the loan will be executed, or (ii) the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the Company. The Company estimates the allowance for credit losses using relevant available information related to past events, current conditions, and reasonable and supportable forecasts. In determining the total allowance for credit losses, the Company calculates the quantitative portion of the allowance for credit losses using a methodology, the Advanced Probability of Default model, a logistic regression model, and adds qualitative adjustments to the model results and the results from any individual loan assessments. The Advanced Probability of Default model estimates the expected lifetime net charge off balance utilizing the following: (i) probability that the loan will stop performing or default; (ii) probability that a loan will pay-off entirely prior to maturity; and (iii) macroeconomic variables, including but not limited to unemployment rates, gross domestic product, and the Treasury Yield Curve. This information is specific to each portfolio segment, though not necessarily solely reliant on internally sourced data. Internal data is supplemented by, but not replaced by, peer data when required, primarily to determine the probability of default. The Company then applies a recovery rate to reflect the recoveries over an approximate 10-year period. The probability of default is estimated by analyzing the relationship between the historical performance of each loan pool and historical economic trends over a complete economic cycle. The probability of default for each pool is adjusted using a statistical model to reflect the current impact of certain macroeconomic variables and their expected changes over a reasonable and supportable forecast period of eight quarters. The Company determined that it was reasonably able to forecast the macroeconomic variables used in the forecast modeling processes with an acceptable degree of confidence for a total of eight quarters. This forecast period is followed by a reversion process whereby the macroeconomic variables are relaxed to revert to the average historical loss rates for periods after the forecasted eight-quarter period. Management qualitatively adjusts the allowance for credit loss model results for risk factors not considered within the quantitative modeling processes but are nonetheless relevant in assessing the expected credit losses within the portfolio segments. These qualitative risk factor adjustments may increase or decrease management’s estimate of expected credit losses by a calculated percentage or amount based upon the estimated level of risk. Qualitative risk factors considered include adjustments for model limitations, management’s adjustments to economic market forecasts and other current or forecasted events not captured in the Company’s historical loss experience. For loans that do not share risk characteristics that are evaluated on an individual basis, specific allocations of the allowance for credit losses are determined by analyzing the borrower’s ability to repay amounts owed, collateral deficiencies, the relative risk grade of the loan and economic conditions affecting the borrower’s industry, among other things. In such cases, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for estimated selling costs if satisfaction of the loan depends on the sale of the collateral. The Company reevaluates the fair value of collateral supporting collateral dependent loans on an annual basis. As disclosed above, the Company has identified the following portfolio segments used in measuring its expected credit losses in the loan portfolio and their respective risk characteristics: The Residential Real Estate Mortgages portfolio includes residential first mortgages and residential second mortgages. The degree of risk in residential real estate lending depends primarily on the loan amount in relation to collateral value, the interest rate and the borrower’s ability to repay in an orderly fashion. Economic trends determined by unemployment rates and other key economic indicators, particularly at the regional and local levels, are closely correlated to the credit quality of these loans. Weak economic trends indicate that the borrowers’ capacity to repay their obligations may be deteriorating. The Home Equity Lines of Credit portfolio includes residential second mortgages in the form of a revolving line of credit that requires interest only payments for a period followed by an amortizing period. These loans have higher risk of default compared to first liens making it harder to rely on loan-to-value ratios and loan balances can fluctuate. These loans are secured by the residential real estate by serving as a second lien behind the first mortgage lien. The Commercial Real Estate portfolio includes commercial loans made to many types of businesses involving retail, multifamily, offices, hotels/single-room occupancy hotels, industrial and other commercial properties. Adverse economic developments or an overbuilt market may impact commercial real estate projects and may result in troubled loans. Trends in vacancy rates of commercial properties impact the credit quality of these loans. High vacancy rates reduce operating revenues and the ability for the properties to produce sufficient cash flow to service debt obligations. The Construction Loans portfolio is comprised of loans to builders and developers primarily for residential, commercial and mixed-use development. In addition to general commercial real estate risks, construction loans have additional risk of cost overruns, market deterioration during construction, lack of permanent financing and no operating history. The Commercial and Industrial portfolio is comprised of loans to many types of businesses for their operating needs of the business. The risk characteristics of these loans vary based on the borrowers’ business and industry as repayment is typically dependent on cash flows generated from the underlying business. These loans may be secured by real estate or other assets or may be unsecured. Liability for Unfunded Commitments (Effective January 1, 2023) Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer needs. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for these off-balance sheet loan commitments is represented by the contractual amount of those instruments. Such financial instruments are recorded when they are funded. The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk through a contractual obligation to extend credit unless that obligation is unconditionally cancellable by the Company. The estimate of expected credit losses generally follows the same methodology as the funded loans by utilizing the loss rates generated for each portfolio segment with an adjustment for the probability of funding to occur. The liability for unfunded commitments, which is recorded in Accrued expenses and other liabilities in the condensed consolidated balance sheets, is adjusted through the provision for (recovery of) credit losses.

The mortgage-backed securities, and a majority of the collateralized mortgage obligations are issued and/or guaranteed by a U.S. government agency (Government National Mortgage Association) or a U.S. government-sponsored enterprise (Federal Home Loan Mortgage Corporation (“Freddie Mac”) or Federal National Mortgage Association (“Fannie Mae”)). The fair value of the private-label collateralized mortgage obligations was $333 and $353 at March 31, 2023 and December 31, 2022, respectively. No securities of any single issuer, other than debt securities issued by the U.S. government, government agency and government-sponsored enterprises, were in excess of 10% of total shareholders’ equity as of March 31, 2023 and December 31, 2022. Information pertaining to sales of available for sale debt securities for the three months ended March 31, 2023 and 2022 is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ March 31, ​ 2023 2022 Proceeds from the sale of debt securities ​ $ 2,977 ​ $ — ​ ​ ​ ​ ​ ​ ​ Gross realized gains ​ $ 1 ​ $ — Gross realized losses ​ (3) ​ — Total net realized losses ​ $ (2) ​ $ — ​ The income tax expense related to the net realized losses was $1 for the three months ended March 31, 2023.

For debt securities in an unrealized loss position, the Company has both the intent and ability to hold these investments and, based on current conditions, the Company does not believe it is likely that it will be required to sell these debt securities prior to recovery of the amortized cost. As the Company had the intent and the ability to hold the debt securities in an unrealized loss position at March 31, 2023, each security with an unrealized loss position was further assessed to determine if a credit loss exists. The Company’s debt, mortgage-backed securities and the majority of the collateralized mortgage obligations are issued by the U.S. government, its agencies and government-sponsored enterprises. Management has concluded that the long history with no credit losses from issuers of U.S. government, its agencies and government-sponsored enterprises indicates an expectation that nonpayment of the amortized cost basis is zero. The Company’s available for sale debt securities are explicitly or implicitly fully guaranteed by the U.S. government. As a result, the Company has not recorded an allowance for credit losses for its available for sale debt securities at March 31, 2023. Similarly, for the same reasons noted above, as of December 31, 2022, the Company determined that the unrealized losses in these securities were due to non-credit-related factors, including changes in interest rates and other market conditions. Equity Securities Equity securities consist of an investment in a qualified community reinvestment act investment fund, which is a publicly-traded mutual fund and an investment in the common equity of Pacific Coast Banker’s Bank, a thinly traded restricted stock. At March 31, 2023 and December 31, 2022, equity securities totaled $4,712 and $4,642, respectively. Equity securities with readily determinable fair values are stated at fair value with realized and unrealized gains and losses reported in non-interest income in the condensed consolidated statements of operations. At March 31, 2023 and December 31, 2022, equity securities with readily determinable fair values were $4,466 and $4,396, respectively. The following is a summary of unrealized and realized gains and losses recognized in the condensed consolidated statements of operations: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ March 31, ​ 2023 2022 Net gain (loss) recorded during the period on equity securities ​ $ 71 ​ $ (236) Less: net gain (loss) recorded during the period on equity securities sold during the period ​ — ​ ​ — Unrealized gain (loss) recorded during the period on equity securities held at the reporting date ​ $ 71 ​ $ (236) ​ The Company has elected to account for its investment in a thinly traded, restricted stock using the measurement alternative for equity securities without readily determinable fair values, resulting in the investment carried at cost based on no evidence of impairment or observable trading activity during the three months ended March 31, 2023 and 2022. The investment was reported at $246 at March 31, 2023 and December 31, 2022.

During the three months ended March 31, 2023, loans with an amortized cost of $41,059 were transferred from loans held for investment to loans held for sale due to management’s change in intent and decision to sell the loans. On the transfer, the Company recorded a $6,478 charge off applied against the allowance for credit losses to reflect these loans at their estimated fair value. As noted above, residential real estate loans with an amortized cost of $3,906 were transferred from loans held for sale. Loans totaling $470,397 and $389,830 were pledged as collateral on the FHLB borrowings at March 31, 2023 and December 31, 2022, respectively. The allowance for credit losses at March 31, 2023 was estimated using the current expected credit loss model. The Company’s estimate of the allowance for credit losses reflects losses expected over the remaining contractual life of the loans. The contractual term does not consider extensions, renewals or modifications unless the Company has identified a loan where the individual borrower is experiencing financial difficulty.

A loan held for investment is classified as nonaccrual, and the accrual of interest on such loan is discontinued, when the contractual payment of principal or interest becomes 90 days past due. In addition, a loan may be placed on nonaccrual at any other time management has serious doubts about further collectability of principal or interest according to the contractual terms, even though the loan is currently performing. A loan held for investment may remain in accrual status if it is in the process of collection and well secured. When a loan held for investment is placed in nonaccrual status, interest accrued but not received is reversed against interest income. Interest received on such loans is applied to the principal balance of the loan until qualifying for return of accrual status. Loans are returned to accrual status after all principal and interest amounts contractually due are made to return the loan to current status and future payments are reasonably assured.

For all classes of financial assets deemed collateral-dependent, the Company estimates the expected credit losses based on the collateral’s fair value less cost to sell. At March 31, 2023, the Company did not have any collateral-dependent loans held for investment where the borrower is experiencing financial difficulty. Modifications to borrowers experiencing financial difficulty may include interest rate reductions, principal or interest forgiveness, forbearances, term extensions, and other actions intended to minimize economic loss and to avoid foreclosure or repossession of collateral. Historically, the Company has provided loan forbearances to residential borrowers when mandated and modified construction loans by providing term extensions. The Company did not have any loans held for investment made to borrowers experiencing financial difficulty that were modified during the three months ended March 31, 2023. The Company did not have any loans held for investment made to borrowers experiencing financial difficulty that were previously modified that subsequently defaulted during the three months ended March 31, 2023. Foreclosure Proceedings At March 31, 2023 and December 31, 2022, the recorded investment of residential mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process totaled $6,130 and $5,711, respectively. Of the loans in formal foreclosure proceedings, $6,130 and $603 were included in loans held for sale in the condensed consolidated balance sheets at March 31, 2023 and December 31, 2022, respectively, and were carried at the lower of amortized cost or fair value. The balance of the loans at December 31, 2022 were classified as held for investment and received an allocation of the allowance for credit losses consistent with a substandard loan loss allocation rate as the loans were classified as substandard. Credit Quality Indicators The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes homogeneous loans, such as residential real estate and other consumer loans, and non-homogeneous loans, such as commercial and industrial, construction and commercial real estate loans. This analysis is performed at least quarterly. The Company uses the following definitions for risk ratings: Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the Company’s credit position at some future date. Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the loan. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, based on currently existing facts, conditions and values, highly questionable and improbable. Loans not meeting the criteria above that are analyzed individually as part of the above-described process are considered pass-rated loans. For residential and consumer loan classes, the Company evaluates credit quality based on the accrual status of the loan.

Residential real estate mortgage loans serviced for others are not included in the condensed consolidated balance sheets. The principal balance of these loans at March 31, 2023 and December 31, 2022 are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, ​ December 31, ​ 2023 2022 Residential real estate mortgage loan portfolios serviced for: ​ ​ FNMA ​ $ 111,126 ​ $ 113,704 FHLB ​ 33,506 ​ 34,282 Private investors ​ 40,230 ​ 43,274 Total ​ $ 184,862 ​ $ 191,260 ​ Custodial escrow balances maintained with these serviced loans were $842 and $380 at March 31, 2023 and December 31, 2022, respectively. These balances are included in noninterest-bearing deposits in the condensed consolidated balance sheets. Activity for mortgage servicing rights and the related valuation allowance are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ March 31, ​ 2023 2022 Mortgage servicing rights: ​ ​ ​ ​ ​ ​ Beginning of period ​ $ 1,840 ​ $ 3,332 Additions ​ ​ — ​ ​ 9 Amortization ​ ​ (74) ​ ​ (253) End of period ​ ​ 1,766 ​ ​ 3,088 Valuation allowance: ​ ​ ​ ​ ​ ​ Beginning of period ​ ​ 46 ​ ​ 610 Additions (recoveries) ​ ​ 17 ​ ​ (410) End of period ​ ​ 63 ​ ​ 200 Mortgage servicing rights, net ​ $ 1,703 ​ $ 2,888 ​ Servicing income, net of amortization of servicing rights and changes in the valuation allowance, was $59 and $443 for the three months ended March 31, 2023 and 2022, respectively. The fair value of mortgage servicing rights was $2,039 and $2,154 at March 31, 2023 and December 31, 2022, respectively. The fair value of mortgage servicing rights is highly sensitive to changes in underlying assumptions. Changes in prepayment speed assumptions have the most significant impact on the estimate of the fair value of mortgage servicing rights. The fair value at March 31, 2023 and December 31, 2022 was determined using discount rates ranging from 10.0% to 12.5%, prepayment speeds with a weighted average of 10.2% (depending on the stratification of the specific right), a weighted average life of the mortgage servicing right of 77 months and a weighted average default rate of 0.2%. Impairment is determined by stratifying the mortgage servicing rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. At March 31, 2023 and December 31, 2022, the carrying amount of certain individual groupings exceeded their fair value, resulting in write-downs to fair value.

The Company, as a thrift holding company, generally is subject to the capital adequacy requirements of the Federal Reserve. Capital adequacy guidelines and prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Prompt corrective action regulations provide five classifications for depository institutions like the Bank, including well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized, although these terms are not used to represent overall financial condition. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weightings and other factors, and the regulators, in their discretion, can require the Company to lower classifications in certain cases. Failure to meet minimum capital requirements can initiate regulatory action that could have a direct material effect on the Company’s business, financial condition and results of operations. The federal banking agencies’ regulations provide for an optional simplified measure of capital adequacy for qualifying community banking organizations (that is, the “CBLR” framework), as implemented pursuant to the Economic Growth, Regulatory Relief and Consumer Protection Act of 2018. The CBLR framework is designed to reduce the burden of the requirements for calculating and reporting risk-based capital ratios for qualifying community banking organizations that opt into the framework. In order to qualify for the CBLR framework, a community banking organization must have (i) a Tier 1 leverage ratio of greater than 9.0%, (ii) less than $10 billion in total consolidated assets, and (iii) limited amounts of off-balance-sheet exposure and trading assets and liabilities. A qualifying community banking organization that opts into the CBLR framework and meets all requirements under the framework will be considered to have met the capital ratio requirements for the “well capitalized” capital category under applicable prompt corrective action regulations and will not be required to report or calculate risk-based capital under generally applicable capital adequacy requirements. Failure to meet the qualifying criteria within the grace period of two reporting periods, or to maintain a leverage ratio of 8.0% or greater, would require the institution to comply with the generally applicable capital adequacy requirements. An eligible banking organization can opt out of the CBLR framework and revert to compliance with general capital adequacy requirements and capital measurements under prompt corrective action regulations without restriction. The Company and the Bank have determined the organization is a qualifying community banking organization and has elected to measure capital adequacy under the CBLR framework, effective as of January 1, 2023. Management believes as of March 31, 2023, the Company and the Bank meet all capital adequacy requirements to which they are subject. The following tables present the consolidated Company’s and the Bank’s actual and minimum required capital amounts and ratios at March 31, 2023 and December 31, 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ To be Well ​ ​ ​ ​ ​ ​ ​ ​ ​ Capitalized Under Prompt Corrective ​ ​ ​ Actual ​ ​ Action Regulations (CBLR Framework) ​ ​ Amount Ratio Amount Ratio March 31, 2023 ​ ​ Tier 1 (core) capital to average total assets (leverage ratio) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ 332,165 ​ 13.49 % 221,576 ​ 9.00 % Bank ​ 406,705 ​ 16.52 % 221,520 ​ 9.00 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For Capital ​ ​ To be Well ​ ​ ​ Actual ​ Adequacy Purposes ​ ​ Capitalized ​ Amount Ratio Amount Ratio ​ Amount Ratio December 31, 2022 ​ ​ ​ ​ Total adjusted capital to risk-weighted assets ​ ​ ​ ​ Consolidated ​ $ 390,591 ​ 25.64 % $ 121,888 ​ 8.00 % ​ N/A ​ N/A ​ Bank ​ 425,159 ​ 27.93 ​ ​ 121,795 ​ 8.00 ​ $ 152,244 ​ 10.00 % Tier 1 (core) capital to risk-weighted assets ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ 332,068 ​ 21.79 ​ ​ 91,416 ​ 6.00 ​ ​ N/A ​ N/A ​ Bank ​ 405,803 ​ 26.65 ​ ​ 91,346 ​ 6.00 ​ ​ 121,795 ​ 8.00 ​ Common Equity Tier 1 (CET1) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ 332,068 ​ 21.79 ​ ​ 68,562 ​ 4.50 ​ ​ N/A ​ N/A ​ Bank ​ 405,803 ​ 26.65 ​ ​ 68,510 ​ 4.50 ​ ​ 98,959 ​ 6.50 ​ Tier 1 (core) capital to average total assets (leverage ratio) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ 332,068 ​ 13.54 ​ ​ 98,073 ​ 4.00 ​ ​ N/A ​ N/A ​ Bank ​ 405,803 ​ 16.56 ​ ​ 98,032 ​ 4.00 ​ ​ 122,540 ​ 5.00 ​ ​ Dividend Restrictions As noted above, federal banking regulations require the Bank to maintain certain capital levels and may limit the dividends paid by the Bank to the holding company or by the holding company to its shareholders. The holding company’s principal source of funds for dividend payments is dividends received from the Bank. Regulatory approval is required if (i) the total capital distributions for the applicable calendar year exceed the sum of the Bank’s net income for that year to date plus the Bank’s retained net income for the preceding two years or (ii) the Bank would not be at least “adequately capitalized” following the distribution. In addition, the Company currently is required to obtain the prior approval of the FRB in order to pay dividends to the Company’s shareholders. Refer to Note 15—Commitments and Contingencies. Also, pursuant to the terms of the subordinated note agreements, the Company may pay dividends if it is well capitalized as defined by regulatory guidelines. The Qualified Thrift Lender (“QTL”) test requires that a minimum of 65% of assets be maintained in qualified thrift investments, including mortgage loans, housing- and real estate-related finance and other specified areas. If the QTL test is not met, limits are placed on growth, branching, new investments, FHLB advances and dividends, or the Bank must convert to a commercial bank charter. Management believes that the QTL test has been met.

Fair Values of Financial Instruments
Fair Values of Financial Instruments	Note 13—Fair Values of Financial Instruments Financial instruments include assets carried at fair value, as well as certain assets and liabilities carried at cost or amortized cost but disclosed at fair value in these condensed consolidated financial statements. Fair value is defined as the exit price, the price that would be received for an asset or paid to transfer a liability in the most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date under current market conditions. The inputs to valuation techniques used to measure fair value are prioritized into a three-level hierarchy. The hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The following methods and significant assumptions are used to estimate fair value: Investment Securities The fair values for investment securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar investment securities (Level 2). For investment securities where quoted prices or market prices of similar investment securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3). The fair value of the collateralized debt obligations, which are categorized as Level 3, is obtained from third-party pricing information. It is determined by calculating discounted cash flows that include spreads that adjust for credit risk and illiquidity. The Company also performs an internal analysis that considers the structure and term of the collateralized debt obligations and the financial condition of the underlying issuers to corroborate the information used from the independent third party. Loans Held for Sale Loans held for sale are carried at the lower of amortized cost or fair value. Loans held for sale may be carried at fair value on a nonrecurring basis when fair value is less than cost. The fair value is based on outstanding commitments from investors or quoted prices for loans with similar characteristics (Level 2). Mortgage Servicing Rights Fair value of mortgage servicing rights is initially determined at the individual grouping level based on an internal valuation model that calculates the present value of estimated future net servicing income. On a quarterly basis, mortgage servicing rights are evaluated for impairment based upon third-party valuations obtained. As disclosed in Note 6—Mortgage Servicing Rights, net, the valuation model utilizes interest rate, prepayment speed and default rate assumptions that market participants would use in estimating future net servicing income (Level 3). Assets Measured at Fair Value on a Recurring Basis The table below presents the assets measured at fair value on a recurring basis categorized by the level of inputs used in the valuation of each asset at March 31, 2023 and December 31, 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at ​ ​ ​ ​ ​ March 31, 2023 ​ ​ ​ ​ ​ Quoted Prices ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ Significant ​ ​ ​ ​ ​ ​ ​ ​ Markets for ​ Other ​ Significant ​ ​ ​ ​ ​ Identical ​ Observable ​ Unobservable ​ ​ ​ ​ ​ Assets ​ Inputs ​ Inputs ​ Total (Level 1) (Level 2) (Level 3) Financial Assets ​ ​ ​ ​ Available for sale debt securities: ​ ​ ​ ​ U.S. Treasury and Agency securities ​ $ 170,271 ​ $ 118,020 ​ $ 52,251 ​ $ — Mortgage-backed securities ​ ​ 35,968 ​ ​ — ​ ​ 35,968 ​ ​ — Collateralized mortgage obligations ​ 136,151 ​ — ​ 136,151 ​ — Collateralized debt obligations ​ 144 ​ — ​ — ​ 144 Equity securities ​ 4,466 ​ 4,466 ​ — ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at ​ ​ ​ ​ ​ December 31, 2022 ​ ​ ​ ​ ​ Quoted Prices ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ Significant ​ ​ ​ ​ ​ ​ ​ ​ Markets for ​ Other ​ Significant ​ ​ ​ ​ ​ Identical ​ Observable ​ Unobservable ​ ​ ​ ​ ​ Assets ​ Inputs ​ Inputs ​ Total (Level 1) (Level 2) (Level 3) Financial Assets ​ ​ ​ ​ Available for sale debt securities: ​ ​ ​ ​ U.S. Treasury and Agency securities ​ $ 168,437 ​ $ 116,355 ​ $ 52,082 ​ $ — Mortgage-backed securities ​ ​ 36,733 ​ ​ — ​ ​ 36,733 ​ ​ — Collateralized mortgage obligations ​ 138,241 ​ — ​ 138,241 ​ — Collateralized debt obligations ​ 147 ​ — ​ — ​ 147 Equity securities ​ ​ 4,396 ​ ​ 4,396 ​ ​ — ​ ​ — ​ The table below presents a reconciliation for all assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three months ended March 31, 2023 and 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements Using Significant ​ ​ Unobservable Inputs (Level 3) ​ ​ Collateralized Debt Obligations ​ ​ Three Months Ended March 31, ​ 2023 2022 Balance of recurring Level 3 assets at beginning of period ​ $ 147 ​ $ 203 Total gains or losses (realized/unrealized): ​ ​ ​ Included in other comprehensive income (loss) ​ (2) ​ 2 Principal maturities/settlements ​ ​ (1) ​ ​ (1) Balance of recurring Level 3 assets at end of period ​ $ 144 ​ $ 204 ​ Assets Measured at Fair Value on a Nonrecurring Basis From time to time, the Company may be required to measure certain other assets at fair value on a nonrecurring basis in accordance with U.S. GAAP. These adjustments to fair value usually result from the application of lower of cost or fair value accounting or write-downs of individual assets. For assets measured at fair value on a nonrecurring basis that were recorded in the condensed consolidated balance sheets at March 31, 2023 and December 31, 2022, the following table provides the level of valuation assumptions used to determine each adjustment and the related carrying value: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at March 31, 2023 ​ ​ ​ Quoted Prices in Significant ​ ​ ​ ​ ​ ​ ​ Active Markets ​ Other ​ Significant ​ ​ ​ ​ ​ Identical ​ Observable ​ Unobservable ​ ​ ​ ​ Assets ​ Inputs ​ Inputs ​ ​ Fair Value ​ (Level 1) ​ (Level 2) ​ (Level 3) Loans held for sale ​ $ 34,581 ​ $ — ​ $ 34,581 ​ $ — Mortgage servicing rights ​ ​ 542 ​ ​ — ​ ​ — ​ ​ 542 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at December 31, 2022 ​ ​ ​ Quoted Prices in Significant ​ ​ ​ ​ ​ ​ ​ Active Markets ​ Other ​ Significant ​ ​ ​ ​ ​ for Identical ​ Observable ​ Unobservable ​ ​ ​ ​ Assets ​ Inputs ​ Inputs ​ ​ Fair Value ​ (Level 1) ​ (Level 2) ​ (Level 3) Mortgage servicing rights ​ $ 391 ​ $ — ​ $ — ​ $ 391 ​ The following tables present quantitative information about Level 3 fair value measurements for assets measured at fair value on a nonrecurring basis at March 31, 2023 and December 31, 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Quantitative Information about Level 3 Fair Value Measurements at March 31, 2023 ​ ​ ​ ​ ​ ​ ​ ​ ​ Range ​ Fair Value Valuation Technique Unobservable Inputs (Weighted Average) (1) Mortgage servicing rights ​ $ 542 ​ Discounted cash flow ​ Discount rate ​ 10.0% - 12.5% ​ ​ ​ Prepayment speed ​ 7.6% - 22.6% ​ ​ ​ ​ ​ ​ ​ Default rate ​ 0.0%-0.2% ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Quantitative Information about Level 3 Fair Value Measurements at December 31, 2022 ​ ​ ​ ​ ​ ​ ​ ​ ​ Range ​ Fair Value Valuation Technique Unobservable Inputs (Weighted Average) (1) Mortgage servicing rights ​ $ 391 ​ Discounted cash flow ​ Discount rate ​ 10.0% - 12.5% ​ ​ ​ ​ ​ ​ ​ Prepayment speed ​ 7.5% - 22.4% ​ ​ ​ ​ ​ ​ ​ Default rate ​ 0.1% - 0.2% (1) The range and weighted average for an asset category consisting of a single investment represents the significant unobservable input used in the fair value of the investment. ​ Fair Value of Financial Instruments The carrying amounts and estimated fair values of financial instruments not carried at fair value at March 31, 2023 and December 31, 2022, are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at March 31, 2023 ​ ​ Carrying ​ Fair ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amount Value Level 1 Level 2 Level 3 Financial Assets ​ ​ ​ ​ ​ ​ Cash and due from banks ​ $ 419,219 ​ $ 419,219 ​ $ 419,219 ​ $ — ​ $ — Interest-bearing time deposits with other banks ​ 934 ​ 934 ​ 934 ​ — ​ — Loans held for sale (1) ​ 3,398 ​ 3,440 ​ — ​ 3,440 ​ — Loans, net ​ 1,513,481 ​ 1,436,596 ​ — ​ — ​ 1,436,596 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial Liabilities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Time deposits ​ 917,161 ​ 912,351 ​ — ​ 912,351 ​ — Federal Home Loan Bank borrowings ​ 50,000 ​ 48,760 ​ — ​ 48,760 ​ — Subordinated notes, net ​ 65,253 ​ 65,533 ​ — ​ 65,533 ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at December 31, 2022 ​ ​ Carrying ​ Fair ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amount Value Level 1 Level 2 Level 3 Financial Assets ​ ​ ​ ​ ​ ​ Cash and due from banks ​ $ 379,798 ​ $ 379,798 ​ $ 379,798 ​ $ — ​ $ — Interest-bearing time deposits with other banks ​ 934 ​ 934 ​ 934 ​ — ​ — Loans held for sale ​ 7,725 ​ 7,833 ​ — ​ 7,833 ​ — Loans, net ​ 1,613,385 ​ 1,516,771 ​ — ​ — ​ 1,516,771 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial Liabilities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Time deposits ​ 861,733 ​ 855,566 ​ — ​ 855,566 ​ — Federal Home Loan Bank borrowings ​ 50,000 ​ 48,360 ​ — ​ 48,360 ​ — Subordinated notes, net ​ 65,271 ​ 65,355 ​ — ​ 65,355 ​ — (1) .

Commitments and Contingencies
Commitments and Contingencies	Note 15—Commitments and Contingencies Financial Instruments with Off-Balance Sheet Risk The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financial needs of its customers. These financial instruments include commitments to extend credit, such as loan commitments and unused credit lines, and standby letters of credit, which are not reflected in the condensed consolidated financial statements. The Company adopted ASU 2016-13, effective January 1, 2023, which requires the Company to estimate expected credit losses for off-balance sheet credit exposures which are unconditionally cancellable. The liability for unfunded commitments is reduced in the period in which the off-balance sheet financial instruments expire, loan funding occurs or is otherwise settled. The Company maintains an estimated liability for unfunded commitments, primarily related to commitments to extend credit, on the condensed consolidated balance sheet. The following presents the activity in the liability for unfunded commitments for the three months ended March 31, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential ​ Commercial ​ ​ ​ ​ Commercial ​ Other ​ ​ ​ Three Months Ended March 31, 2023 ​ Real Estate ​ Real Estate ​ Construction ​ and Industrial ​ Consumer ​ Total Liability for unfunded commitments: ​ ​ ​ ​ ​ ​ Balance at the beginning of the period ​ $ — ​ $ — ​ $ — ​ $ — ​ $ — ​ $ — Adoption of ASU 2016-13 ​ 53 ​ 125 ​ 398 ​ 3 ​ — ​ 579 Increase (decrease) in provision for (recovery of) credit losses ​ 49 ​ 30 ​ (190) ​ 1 ​ — ​ (110) Total ending balance ​ $ 102 ​ $ 155 ​ $ 208 ​ $ 4 ​ $ — ​ $ 469 ​ Unfunded Commitments to Extend Credit A commitment to extend credit, such as a loan commitment, credit line and overdraft protection, is a legally binding agreement to lend funds to a customer, usually at a stated interest rate and for a specific purpose. Such commitments have fixed expiration dates and generally require a fee. The extension of a commitment gives rise to credit risk. The actual liquidity requirements or credit risk that the Company may experience is expected to be lower than the contractual amount of commitments to extend credit because a significant portion of those commitments are expected to expire without being used. Certain commitments are subject to loan agreements containing covenants regarding the financial performance of the customer that must be met before the Company is required to fund the commitment. The Company uses the same credit policies in making commitments to extend credit as it does in making loans. The commitments outstanding to make loans include primarily residential real estate loans that are made for a period of 90 days or less. At March 31, 2023, there were no outstanding commitments to make loans. Unused Lines of Credit The Company also issues credit lines to meet customer financing needs. At March 31, 2023, the unused lines of credit include residential second mortgages of $10,773, construction loans of $5,974 and commercial and industrial loans of $972, totaling $17,719. These variable-rate unused lines of credit commitments have interest rates ranging from 4.72% to 10.13% at March 31, 2023 with maturities ranging from 3 months to 23 years. Standby Letters of Credit Standby letters of credit are issued on behalf of customers in connection with construction contracts between the customers and third parties. Under standby letters of credit, the Company assures that the third parties will receive specified funds if customers fail to meet their contractual obligations. The credit risk to the Company arises from its obligation to make payment in the event of a customer’s contractual default. The maximum amount of potential future payments guaranteed by the Company is limited to the contractual amount of these letters. Collateral may be obtained at exercise of the commitment. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. The following is a summary of the total amount of unfunded commitments to extend credit and standby letters of credit outstanding at March 31, 2023 and December 31, 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, ​ December 31, ​ 2023 2022 Commitments to make loans ​ $ — ​ $ — Unused lines of credit ​ 17,719 ​ 20,865 Standby letters of credit ​ 24 ​ 24 ​ Legal Proceedings The Company and its subsidiaries may be subject to legal actions and claims arising from contracts or other matters from time to time in the ordinary course of business. Management is not aware of any pending or threatened legal proceedings, except as described below, that are considered other than routine legal proceedings. The Company believes that the ultimate disposition or resolution of its routine legal proceedings, in the aggregate, are immaterial to its financial position, results of operations or liquidity. The Bank has received grand jury subpoenas from the U.S. Department of Justice (the “DOJ”) beginning in 2020 requesting the production of documents and information in connection with an investigation focused on the Bank’s Advantage Loan Program and related issues, including residential lending practices and public disclosures about that program contained in the Company’s filings with the SEC. On March 15, 2023, the Company entered into a Plea Agreement (the “Plea Agreement”) with the DOJ, resolving the DOJ’s investigation. Under the Plea Agreement, the Company has agreed to plead guilty to one count of securities fraud primarily relating to disclosures with respect to the Advantage Loan Program contained in the Company’s 2017 IPO Registration Statement and its immediately following Annual Reports on Form 10-K filed in March 2018 and March 2019; pay $27,239 in restitution for the benefit of non-insider victim shareholders; further enhance its compliance program and internal controls with respect to securities law compliance; and provide periodic reports to the DOJ with respect to compliance matters. No criminal fine was imposed. The Company’s obligations under the Plea Agreement are generally effective for three years. This resolution releases the Company, as well as the Bank, from further prosecution for securities fraud and underlying mortgage fraud in the Advantage Loan Program. At a hearing held on April 19, 2023, the District Court for the Eastern District of Michigan preliminarily accepted the Plea Agreement, subject to the final court hearing. The Plea Agreement remains subject to final court approval. In addition, the Company remains under a formal investigation by the SEC. This investigation appears to be focused on accounting, financial reporting and disclosure matters, as well as the Company’s internal controls, related to the Advantage Loan Program. The Company has received document and information requests from the SEC and has fully cooperated with this investigation. Adverse findings in the SEC investigation could result in material losses due to penalties, disgorgement, costs and/or expenses imposed on the Company, which could have a material adverse effect on the Company’s future operations, financial condition, growth or other aspects of its business. At March 31, 2023 and December 31, 2022, the Company has a liability for contingent losses of $27,239 for the outcome of the pending investigations. There can be no assurance (i) that the accrual for contingent losses will be sufficient to cover the cost of any payments required by the DOJ resolution, or (ii) that such costs will not materially exceed such accrual and have a further material impact on the Company’s business, financial condition or results of operations. The Bank has incurred and expects to continue to incur significant costs in its efforts to respond to the governmental investigations, including to reimburse third parties for the legal costs pursuant to requests for indemnification and advancement of expenses, which are reflected in the Company’s condensed consolidated statements of operations for the three months ended March 31, 2023 and 2022. Mortgage Repurchase Liability The Company has previously sold portfolio loans originated under the Advantage Loan Program to private investors in the secondary market. The Company also sells conventional residential real estate loans (which excludes Advantage Loan Program loans) in the secondary market primarily to Fannie Mae on an ongoing basis. In connection with these loans sold, the Company makes customary representations and warranties about various characteristics of each loan. The Company may be required pursuant to the terms of the applicable mortgage loan purchase and sale agreements to repurchase any previously sold loan or indemnify (make whole) the investor for which the representation or warranty of the Company proves to be inaccurate, incomplete or misleading. In the event of a repurchase, the Company is typically required to pay the unpaid principal balance, the proportionate premium received when selling the loan and certain expenses. As a result, the Company may incur a loss with respect to each repurchased loan. To avoid the uncertainty of audits and inquiries by third-party investors in the Advantage Loan Program, beginning at the end of the second quarter of 2020, the Company commenced making offers to each of those investors to repurchase 100% of the previously sold Advantage Loan Program loans. These loans were previously sold to third-party investors with servicing of the loan retained. Losses expected to be incurred upon the repurchase of such loans were reflected in the mortgage repurchase liability. Pursuant to the existing agreements with such investors, the Company also agreed to repurchase additional pools of Advantage Loan Program loans at the predetermined repurchase prices as stated in the agreements. At March 31, 2023, there was an outstanding agreement to repurchase an additional pool of Advantage Loan Program loans with an unpaid principal balance of $20,471 that extends to July 2025, with the final decision to effect any such repurchase, as determined by the applicable investor. At March 31, 2023 and December 31, 2022, the mortgage repurchase liability was $929 and $809, respectively, which is included in accrued expenses and other liabilities in the condensed consolidated balance sheets. The unpaid principal balance of residential real estate loans sold that were subject to potential repurchase obligations in the event of breach of representations and warranties totaled $103,034 and $112,542 at March 31, 2023 and December 31, 2022, respectively, including Advantage Loan Program loans totaling $40,230 and $43,274 at March 31, 2023 and December 31, 2022, respectively. Activity in the mortgage repurchase liability was as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ March 31, ​ 2023 2022 Balance, beginning of period ​ $ 809 ​ $ 2,954 Net provision (recovery) ​ 120 ​ (213) Balance, end of the period ​ $ 929 ​ $ 2,741 ​

Summary of Significant Accounting Policies
Principles of Consolidation	Principles of Consolidation The accompanying condensed consolidated financial statements have been prepared in conformity with U.S. GAAP. The condensed consolidated financial statements include the results of Sterling Bancorp, Inc. and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Due to the inherent uncertainty involved in making estimates, actual results reported in the future periods may be based upon amounts that could differ from those estimates.
Concentration of Credit Risk	Concentration of Credit Risk The loan portfolio consists primarily of residential real estate loans, which are collateralized by real estate. At March 31, 2023 and December 31, 2022, residential real estate loans accounted for 83% and 84%, respectively, of total gross loans. In addition, most of these residential loans and other commercial loans have been made to individuals and businesses in the state of California, which are dependent on the area economy for their livelihoods and servicing of their loan obligation. At March 31, 2023 and December 31, 2022, approximately 81% of gross loans were originated with respect to properties or businesses located in the state of California. In December 2019, the Company terminated a loan product consisting of one-, three-, five- or seven-year adjustable-rate mortgages that required a down payment of at least 35% (also referred to herein as “Advantage Loan Program loans”) which continues to be the largest portion of gross residential loans. An internal review of the Advantage Loan Program indicated that certain employees engaged in misconduct in connection with the origination of a significant number of such loans, including with respect to verification of income, the amount of income reported for borrowers, reliance on third parties and related documentation. Refer to Note 15—Commitments and Contingencies. Advantage Loan Program loans (including residential real estate loans held for sale of $36,234 and $6,181 at March 31, 2023 and December 31, 2022, of which $26,074 and $1,942 were on nonaccrual status as of those respective dates) totaled $824,033 and $880,373, or 62% and 63% of gross residential loans, at March 31, 2023 and December 31, 2022, respectively.
Investment Securities	Investment Securities Debt Securities (Effective January 1, 2023) ​ Debt securities are classified as either available for sale or held to maturity. Management determines the classification of the debt securities when they are purchased. All debt securities were categorized as available for sale as of March 31, 2023 and December 31, 2022. Debt securities available for sale are stated at fair value, with unrealized gains and losses reported in accumulated other comprehensive loss, net of income taxes. The amortized cost of debt securities is adjusted for amortization of premiums (noncallable) and accretion of discounts. The Company amortizes premiums and accretes discounts using the effective interest method over the contractual life of the individual securities or, in the case of asset-backed securities, using the effective yield method over the estimated life of the individual securities. Interest income includes amortization or accretion of purchase premium or discount. Gains and losses realized on the sales of available for sale debt securities are recorded on the settlement date and determined using the specific identification method. For available for sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For available for sale debt securities that do not meet the aforementioned criteria, the Company evaluates at the individual security level 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 cost, 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. 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. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income, net of income taxes. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit losses. Losses are charged against the allowance for credit losses when management believes the uncollectibility of an available for sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on available for sale debt securities is recorded separately from the amortized cost basis of the debt securities in the condensed consolidated balance sheets and is excluded from the estimate of credit losses. ​ Equity Securities Equity securities with readily determinable fair values are stated at fair value with unrealized and realized gains and losses reported in income. Those equity securities without readily determinable fair values are recorded at cost less any impairments, adjusted for subsequent observable price changes in orderly transactions for an identical or similar investment of the same issuer. Any changes in the carrying value of the equity investments are recognized in income. Management performs a qualitative assessment each reporting period to identify impairment of equity securities without readily determinable fair values. When a qualitative assessment indicates that an impairment exists, management determines the fair value of the investment and if the fair value is less than the investment’s carrying value, an impairment charge is recorded in income equal to the difference between the fair value and the carrying amount of the investment. ​
Loans Held for Sale	Loans Held for Sale The Company originates certain loans intended for sale in the secondary market. Loans held for sale are carried at the lower of amortized cost or fair value on an individual loan basis. The fair value of loans held for sale are primarily determined based on quoted prices for similar loans in active markets or outstanding commitments from third-party investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to non-interest income in the condensed consolidated statements of operations. Performing residential real estate loans that are held for sale are generally sold with servicing rights retained. The carrying value of mortgage loans sold is reduced by the amount allocated to the servicing right. On the sale of an originated loan, the servicing right is recorded at its estimated fair value. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold and are recorded as a component of non-interest income. Loans that are originated and classified as held for investment are periodically sold in order to manage liquidity, asset credit quality, interest rate risk or concentration risk. Loans that are reclassified into loans held for sale from loans held for investment, due to a change in intent, are recorded at the lower of cost or fair value.
Loans	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at amortized cost, net of the allowance for credit losses. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts, and deferred loan fees and costs. Accrued interest receivable related to loans is recorded separately from the amortized cost basis of loans on the condensed consolidated balance sheets and is excluded from the estimate of credit losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct loan origination costs, are deferred and amortized over the contractual lives of the respective loans as a yield adjustment using the effective interest method. Other credit-related fees are recognized as fee income, as a component of non-interest income. Interest income on loans is accrued as earned using the interest method over the term of the loan. The accrual of interest income is discontinued at the time the loan is 90 days past due or earlier if conditions warrant and placed on nonaccrual status. In all cases, loans are placed on nonaccrual status at an earlier date if collection of principal or interest is considered doubtful. All interest accrued and not received for loans placed on nonaccrual status is reversed against interest income. Any payments received on nonaccrual loans are applied to interest income on a cash basis if the loan is considered well secured. Otherwise, all payments received are applied first to outstanding loan principal amounts and then to the recovery of the charged off loan amounts. Any excess is treated as a recovery of interest and fees. Loans are returned to accrual status after all principal and interest amounts contractually due are made and future payments are reasonably assured.
Allowance for Credit Losses - Loans (Effective January 1, 2023)	Allowance for Credit Losses - Loans (Effective January 1, 2023) The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of held for investment loans to present the net amount expected to be collected on the loans. The allowance for credit losses is adjusted through a charge (recovery) to provision for (recovery of) credit losses in the condensed consolidated statements of operations. When the Company determines that all or a portion of a loan is uncollectible, the appropriate amount is written off, and the allowance for credit losses is reduced by the same amount. The Company applies judgment to determine when a loan is deemed uncollectible; however, generally a loan will be considered uncollectible no later than when all efforts at collection have been exhausted. Subsequent recoveries, if any, are credited to the allowance for credit losses when received. Portions of the allowance for credit losses may be allocated for specific credits; however, the entire allowance for credit losses is available for any credit that, in management’s judgment, should be charged off. The Company estimates the allowance for credit losses on loans based on the underlying loans’ amortized cost. If the collection of principal becomes uncertain, the Company stops accruing interest and reverses the accrued but unpaid interest against interest income. The Company has made a policy election to exclude accrued interest receivable from the measurement of the allowance for credit losses. The allowance for credit losses process involves procedures to appropriately consider the unique characteristics of the Company’s portfolio segments. The allowance for credit losses is measured on a collective (pool) basis for portfolios of loans with similar risk characteristics and risk profiles. The Company’s portfolio segments include the following: (i) commercial real estate, (ii) commercial construction, (iii) commercial and industrial, (iv) residential real estate and (v) home equity lines of credit. These portfolio segments were identified based on their common characteristics: loan type/purpose of loan, underlying collateral type, historical/expected credit loss patterns, availability of credit quality indicators (i.e., FICO, risk rating, delinquency) and completeness of the historical information. Loans which do not share risk characteristics The amount of the allowance for credit losses represents management’s best estimate of current expected credit losses on loans considering available information from internal and external sources, which is relevant to assessing collectability of the loans over the loans’ contractual terms, adjusted for expected prepayments. The contractual term excludes expected extensions, renewals and modifications unless: (i) management has a reasonable expectation at the reporting date that an individual borrower is experiencing financial difficulty and a modification of the loan will be executed, or (ii) the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the Company. The Company estimates the allowance for credit losses using relevant available information related to past events, current conditions, and reasonable and supportable forecasts. In determining the total allowance for credit losses, the Company calculates the quantitative portion of the allowance for credit losses using a methodology, the Advanced Probability of Default model, a logistic regression model, and adds qualitative adjustments to the model results and the results from any individual loan assessments. The Advanced Probability of Default model estimates the expected lifetime net charge off balance utilizing the following: (i) probability that the loan will stop performing or default; (ii) probability that a loan will pay-off entirely prior to maturity; and (iii) macroeconomic variables, including but not limited to unemployment rates, gross domestic product, and the Treasury Yield Curve. This information is specific to each portfolio segment, though not necessarily solely reliant on internally sourced data. Internal data is supplemented by, but not replaced by, peer data when required, primarily to determine the probability of default. The Company then applies a recovery rate to reflect the recoveries over an approximate 10-year period. The probability of default is estimated by analyzing the relationship between the historical performance of each loan pool and historical economic trends over a complete economic cycle. The probability of default for each pool is adjusted using a statistical model to reflect the current impact of certain macroeconomic variables and their expected changes over a reasonable and supportable forecast period of eight quarters. The Company determined that it was reasonably able to forecast the macroeconomic variables used in the forecast modeling processes with an acceptable degree of confidence for a total of eight quarters. This forecast period is followed by a reversion process whereby the macroeconomic variables are relaxed to revert to the average historical loss rates for periods after the forecasted eight-quarter period. Management qualitatively adjusts the allowance for credit loss model results for risk factors not considered within the quantitative modeling processes but are nonetheless relevant in assessing the expected credit losses within the portfolio segments. These qualitative risk factor adjustments may increase or decrease management’s estimate of expected credit losses by a calculated percentage or amount based upon the estimated level of risk. Qualitative risk factors considered include adjustments for model limitations, management’s adjustments to economic market forecasts and other current or forecasted events not captured in the Company’s historical loss experience. For loans that do not share risk characteristics that are evaluated on an individual basis, specific allocations of the allowance for credit losses are determined by analyzing the borrower’s ability to repay amounts owed, collateral deficiencies, the relative risk grade of the loan and economic conditions affecting the borrower’s industry, among other things. In such cases, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for estimated selling costs if satisfaction of the loan depends on the sale of the collateral. The Company reevaluates the fair value of collateral supporting collateral dependent loans on an annual basis. As disclosed above, the Company has identified the following portfolio segments used in measuring its expected credit losses in the loan portfolio and their respective risk characteristics: The Residential Real Estate Mortgages portfolio includes residential first mortgages and residential second mortgages. The degree of risk in residential real estate lending depends primarily on the loan amount in relation to collateral value, the interest rate and the borrower’s ability to repay in an orderly fashion. Economic trends determined by unemployment rates and other key economic indicators, particularly at the regional and local levels, are closely correlated to the credit quality of these loans. Weak economic trends indicate that the borrowers’ capacity to repay their obligations may be deteriorating. The Home Equity Lines of Credit portfolio includes residential second mortgages in the form of a revolving line of credit that requires interest only payments for a period followed by an amortizing period. These loans have higher risk of default compared to first liens making it harder to rely on loan-to-value ratios and loan balances can fluctuate. These loans are secured by the residential real estate by serving as a second lien behind the first mortgage lien. The Commercial Real Estate portfolio includes commercial loans made to many types of businesses involving retail, multifamily, offices, hotels/single-room occupancy hotels, industrial and other commercial properties. Adverse economic developments or an overbuilt market may impact commercial real estate projects and may result in troubled loans. Trends in vacancy rates of commercial properties impact the credit quality of these loans. High vacancy rates reduce operating revenues and the ability for the properties to produce sufficient cash flow to service debt obligations. The Construction Loans portfolio is comprised of loans to builders and developers primarily for residential, commercial and mixed-use development. In addition to general commercial real estate risks, construction loans have additional risk of cost overruns, market deterioration during construction, lack of permanent financing and no operating history. The Commercial and Industrial portfolio is comprised of loans to many types of businesses for their operating needs of the business. The risk characteristics of these loans vary based on the borrowers’ business and industry as repayment is typically dependent on cash flows generated from the underlying business. These loans may be secured by real estate or other assets or may be unsecured.
Liability for Unfunded Commitments	Liability for Unfunded Commitments (Effective January 1, 2023) Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer needs. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for these off-balance sheet loan commitments is represented by the contractual amount of those instruments. Such financial instruments are recorded when they are funded. The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk through a contractual obligation to extend credit unless that obligation is unconditionally cancellable by the Company. The estimate of expected credit losses generally follows the same methodology as the funded loans by utilizing the loss rates generated for each portfolio segment with an adjustment for the probability of funding to occur. The liability for unfunded commitments, which is recorded in Accrued expenses and other liabilities in the condensed consolidated balance sheets, is adjusted through the provision for (recovery of) credit losses.
