Accounting Policies [Abstract]
BASIS OF PRESENTATION	NOTE 1 – BASIS OF PRESENTATION BayCom Corp (the “Company”) is a bank holding company headquartered in Walnut Creek, California. United Business Bank (the “Bank”), the Company’s wholly owned banking subsidiary, is a California state-chartered bank which provides a broad range of financial services primarily to local small and mid-sized businesses, service professionals and individuals. In its 19 years of operation, the Bank has grown to 35 full-service banking branches, with 16 locations in California, one in Nevada, two in Washington, five in New Mexico and 11 in Colorado. The condensed consolidated financial statements include the accounts of the Company and the Bank. All intercompany transactions and balances have been eliminated in consolidation. The condensed consolidated financial statements include all adjustments of a normal and recurring nature, which are, in the opinion of management, necessary for a fair presentation of the financial position and results of operations for the periods presented. Amounts presented in the consolidated financial statements and footnote tables are rounded and presented to the nearest thousands of dollars except per share amounts. If the amounts are above $1.0 million, they are rounded one decimal point, and if they are above $1.0 billion, they are rounded two decimal points. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all information and footnotes normally included in annual financial statements prepared in conformity with accounting principles generally accepted in the United States of America. Accordingly, these condensed consolidated financial statements should be read in conjunction with the consolidated audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. Results of operations for interim periods are not necessarily indicative of results for the full year. Certain prior year information has been reclassified to conform to the current year presentation. None of the reclassifications impacted consolidated net income, earnings per share or shareholders’ equity. On April 5, 2012, the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”) was signed into law. The JOBS Act contains provisions that, among other things, reduce certain reporting requirements for a public company that qualified as an “emerging growth company,” or EGC. The Company qualified as an EGC and remained an EGC until December 31, 2023, the last day of the Company’s fiscal year following the fifth anniversary of the completion of the Company’s initial public offering. As an EGC, we were permitted to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements were made applicable to private companies. We took advantage of the benefits of this extended transition period; accordingly, our condensed consolidated financial statements for periods prior to our exit from EGC status may not be comparable to companies that comply with such new or revised accounting standards. Restatement of Previously Issued Consolidated Financial Statements ​ On July 18, 2023, the audit committee of the Company’s board of directors concluded that the Company’s previously issued unaudited interim consolidated financial statements for the period ended March 31, 2023 and the consolidated financial statements for the year ended December 31, 2022, as well as for the unaudited interim periods included in that fiscal year (collectively, “Restated Periods”), should no longer be relied upon because of errors related to the accounting for unrealized losses on preferred equity securities that resulted in material misstatements of noninterest income and accumulated other comprehensive income. ​ At the time of its purchase of the preferred equity securities for investment purposes, the Company inappropriately accounted for them as AFS debt securities under Accounting Standards Codification (“ASC”) Topic 320 – Investments-Debt Securities Investments-Equity Securities ​ On July 25, 2023, the Company filed amendments to its Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2023, September 30, 2022, June 30, 2022, and March 31, 2022, and its Form 10-K for the year ended December 31, 2022, (the “Original Reports”) with the Securities and Exchange Commission (“SEC”), to reflect the restatement of the Company’s consolidated financial statements for the Restated Periods (the “Amended Form 10-Qs” and the “Amended Form 10-K,” collectively, the “Amended Reports”). ​ As disclosed in the Original Reports, the Company recorded the change, net of taxes, in the fair value of preferred equity securities as part of other comprehensive loss, net of taxes, under ASC Topic 320 – Investments-Debt Securities Investments-Equity Securities ​ For additional information on the effects of the restatement, see Note 2 Restatement of Consolidated Financial Statements in the Notes to Consolidated Financial Statements contained in the Amended Form 10-K and Note 3. Restatement of the Consolidated Financial Statements in the Notes to Condensed Consolidated Financial Statements contained in each of the Amended Form 10-Qs.

ACCOUNTING GUIDANCE NOT YET EFF

ACCOUNTING GUIDANCE NOT YET EFFECTIVE AND ADOPTED ACCOUNTING GUIDANCE	3 Months Ended
	Mar. 31, 2024
Accounting Standards Update and Change in Accounting Principle [Abstract]
ACCOUNTING GUIDANCE NOT YET EFFECTIVE AND ADOPTED ACCOUNTING GUIDANCE	NOTE 2 - ACCOUNTING GUIDANCE NOT YET EFFECTIVE AND ADOPTED ACCOUNTING GUIDANCE Accounting Guidance Adopted in 2024 On January 1, 2024, the Company adopted Accounting Standards Update (“ASU”) 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method, a consensus of the Emerging Issues Task Force. ASU 2023-02 allows an entity the option to apply the proportional amortization method of accounting to other equity investments that are made for the primary purpose of receiving tax credits or other income tax benefits if certain conditions are met. Prior to this ASU, the application of the proportional amortization method of accounting was limited to investments in low-income housing tax credit structures. The proportional amortization method of accounting results in the amortization of applicable investments, as well as the related income tax credits or other income tax benefits received, being presented on a single line in the statements of income, income tax expense. Under this ASU, an entity has the option to apply the proportional amortization method of accounting to applicable investments on a tax-credit-program-by-tax-credit program basis. In addition, the amendments in this ASU require that all tax equity investments accounted for using the proportional amortization method use the delayed equity contribution guidance in paragraph 323-740-25-3, requiring a liability to be recognized for delayed equity contributions that are unconditional and legally binding or for equity contributions that are contingent upon a future event when that contingent event becomes probable. Under this ASU, low-income housing tax credit investments for which the proportional amortization method is not applied can no longer be accounted for using the delayed equity contribution guidance. Further, this ASU specifies that impairment of low-income housing tax credit investments not accounted for using the equity method must apply the impairment guidance in Subtopic 323-10: Investments - Equity Method and Joint Ventures - Overall. This ASU also clarifies that for low-income housing tax credit investments not accounted for under the proportional amortization method or the equity method, an entity shall account for them under Topic 321: Investments - Equity Securities . The amendments in the ASU also require additional disclosures in interim and annual periods concerning investments for which the proportional amortization method is applied, including (i) the nature of tax equity investments, and (ii) the effect of tax equity investments and related income tax credits and other income tax benefits on the financial position and results of operations. ASU 2023-02 is effective for the Company for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The adoption of ASU 2023-02 did not have a material impact on the Company's consolidated financial statements and related disclosures. ​ Fair Value Measurement (Topic 820) - In June 2022, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2022-03, Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. The guidance in the ASU clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account on the equity security and, therefore, is not considered in measuring fair value. The ASU also requires additional disclosures about the restriction. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. The adoption of ASU 2022-03 did not have a significant impact on the Company's consolidated financial statements and related disclosures. Recent Accounting Guidance Not Yet Effective Business Combinations (Topic 805) - In August 2023, the FASB issued ASU 2023-05, Business Combinations—Joint Venture (JV) Formations: Recognition and Initial Measurement. The guidance requires newly-formed JVs to apply a new basis of accounting to all of its contributed net assets, which results in the JV initially measuring its contributed net assets under ASC 805-20, Business Combinations. The new guidance would be applied prospectively and is effective for all newly-formed joint venture entities with a formation date on or after January 1, 2025, with early adoption permitted. The Company is evaluating the accounting and disclosure requirements of this update and does not expect them to have a material effect on the consolidated financial statements. ​ Segment Reporting – Improvements to Reportable Segment Disclosures (Topic 280) – In November 2023, the FASB issued ASU 2023-07 to enhance disclosures about significant segment expenses for public entities reporting segment information under Topic 280. It requires that a public entity disclose, on an annual and interim basis, significant expense categories for each reportable segment. Significant expense categories are derived from expenses that are 1) regularly reported to an entity’s chief operating decision-maker ("CODM"), and 2) included in a segment’s reported measure of profit or loss. The disclosures should include an amount for "other segment items," reflecting the difference between 1) segment revenue less significant segment expenses, and 2) the reportable segment’s profit or loss measures. It requires that a public entity disclose the title and position of the CODM and how the CODM uses the reported measure of profit or loss to assess segment performance and to allocate resources. Further it clarifies that entities with a single reportable segment must disclose both new and existing segment reporting requirements. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Entities must adopt the guidance on a retrospective basis. The Company is evaluating the accounting and disclosure requirements of this update and does not expect them to have a material effect on the consolidated financial statements. ​ Income Taxes – Improvements to Income Tax Disclosures (Topic 740) – In December 2023, the FASB issued ASU 2023-09 to provide additional transparency into an entity’s income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The standard requires that public business entities disclose, on an annual basis, specific categories in the rate reconciliation and additional information for reconciling items meeting a certain quantitative threshold. The amendments also require that entities disclose on an annual basis: 1) income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes and 2) the income taxes paid (net of refunds received) disaggregated by individual jurisdictions exceeding 5% of total income taxes paid (net of refunds received). The amendments are effective for public business entities for annual periods beginning after December 15, 2024. The Company is evaluating the accounting and disclosure requirements of this update and does not expect them to have a material effect on the consolidated financial statements. ​ ​ ​ ​ ​ ​ ​ ​ ​

At December 31, 2023, the Company held 334 investment securities, of which 297 were in an unrealized loss position for more than twelve months and 22 were in an unrealized loss position for less than twelve months. The Company anticipates full recovery of amortized cost with respect to these securities at maturity or sooner in the event of a more favorable market interest rate environment. Allowance for credit losses on investment debt securities available-for-sale ​ Securities that were in an unrealized loss position as of March 31, 2024 were evaluated to determine whether the decline in fair value below the amortized cost basis resulted from a credit loss or changes in required yields by investors in these types of securities, among other factors. This assessment first includes a determination of whether 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 recovery of its amortized cost basis less any current-period credit losses. In making this assessment, management considers the nature of the security and any related government guarantees, any changes to the rating of the security by a rating agency, creditworthiness of the issuers/guarantors, the underlying collateral, the financial conditions and prospects of the issuer, and any adverse conditions specifically related to the security, among other factors. As of March 31, 2024, the Company expects to recover the amortized cost basis of its securities, has no present intent to sell any investment securities with unrealized losses and it is not more likely than not that we will not be required to sell securities with unrealized losses before recovery of their amortized cost and the decline in fair value is largely attributed to changes in interest rates and other market conditions. The issuers of these securities continue to make timely principal and interest payments. No allowances for credit losses have been recognized on investment debt securities AFS in an unrealized loss position, as management does not believe any of the securities are impaired due to reasons of credit quality at March 31, 2024. ​ ​ ​ ​ Equity Securities ​ The Company recognized a net gain on equity securities of $573,000 and a net loss on equity securities of $896,000 for the three months ended March 31, 2024 and 2023, respectively. Equity securities were $13.2 million and $12.6 million as of March 31, 2024 and December 31, 2023, respectively.

At time of restructuring, these loans are generally placed on nonaccrual. These loans may be returned to accrual status after the borrower demonstrated performance with the modified terms for a sustained period of time (generally six months The ACL on a is measured using the same method as individually evaluated loans. ​ A summary of modified loans to borrowers experiencing financial difficulty by type of concession and type of loan, as of the dates indicated, is set forth below (number of loans not in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Number of Rate Term Rate & term ​ ​ ​ % of Total ​ ​ loans ​ modification ​ modification ​ modification ​ Total ​ loans outstanding March 31, 2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial and industrial 2 ​ $ — ​ $ 117 ​ $ — ​ $ 117 ​ ​ 0.07 % Construction and land — ​ — ​ — ​ — ​ — ​ — % Commercial real estate 4 ​ — ​ 2,143 ​ — ​ 2,143 ​ 0.13 % Residential 1 ​ — ​ ​ 767 ​ — ​ 767 ​ 0.91 % Consumer — ​ — ​ — ​ — ​ — ​ — % Total 7 ​ $ — ​ $ 3,027 ​ $ — ​ $ 3,027 ​ ​ 0.16 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Number of Rate Term Rate & term ​ ​ ​ % of Total ​ ​ loans ​ modification ​ modification ​ modification ​ Total ​ loans outstanding March 31, 2023 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial and industrial 3 ​ $ — ​ $ 154 ​ $ — ​ $ 154 ​ ​ 0.08 % Construction and land — ​ — ​ — ​ — ​ — ​ — % Commercial real estate 6 ​ — ​ 5,112 ​ — ​ 5,112 ​ 0.29 % Residential 1 ​ — ​ 829 ​ — ​ 829 ​ 0.86 % Consumer — ​ — ​ — ​ — ​ — ​ — % Total 10 ​ $ — ​ $ 6,095 ​ $ — ​ $ 6,095 ​ ​ 0.30 % ​ For the three months ended March 31, 2024 and 2023, the C ompany recorded $1.3 million of charge-offs and no charge-offs for modified loans to borrowers experiencing financial difficulty, respectively. ​ As of March 31, 2024 and December 31, 2023, individually evaluated modified loans to borrowers experiencing financial difficulty had a related allowance of $42,000 and $1.3 million, respectively. As of March 31, 2024 and December 31, 2023, none of modified loans to borrowers experiencing financial difficulty were performing in accordance with their modified terms. Accruing modified loans to borrowers experiencing financial difficulty are included in the loans individually evaluated as part of the calculation of the allowance for credit losses for loans. ​ Risk Rating System The Company evaluates and assigns a risk grade to each loan based on certain criteria to assess the credit quality of the loan. The assignment of a risk rating is done for each individual loan. Loans are graded from inception and on a continuing basis until the debt is repaid. Any adverse or beneficial trends will trigger a review of the loan risk rating. Each loan is assigned a risk grade based on its characteristics. Loans with low to average credit risk are assigned a lower risk grade than those with higher credit risk as determined by the individual loan characteristics. The Company’s Pass loans include loans with acceptable business or individual credit risk where the borrower’s operations, cash flow or financial condition provides evidence of low to average levels of risk. Loans that are assigned higher risk grades are loans that exhibit the following characteristics: Special Mention loans have potential weaknesses that deserve close attention. If left uncorrected, these potential weaknesses may result in a deterioration of the repayment prospects for the loan or in the Company’s credit position at some future date. Special Mention loans are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification. A Special Mention rating is a temporary rating, pending the occurrence of an event that would cause the risk rating either to improve or to be downgraded. Loans in this category would be characterized by any of the following situations: ● Credit that is currently protected but is potentially a weak asset; ● Credit that is difficult to manage because of an inadequate loan agreement, the condition of and/or control over collateral, failure to obtain proper documentation, or any other deviation from product lending practices; and ● Adverse financial trends. Substandard loans are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged. Loans classified substandard must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Substandard loans are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. The potential loss does not have to be recognizable in an individual credit for that credit to be risk rated Substandard. A loan can be fully and adequately secured and still be considered Substandard. Some characteristics of Substandard loans are: ● Inability to service debt from ordinary and recurring cash flow; ● Chronic delinquency; ● Reliance upon alternative sources of repayment; ● Term loans that are granted on liberal terms because the borrower cannot service normal payments for that type of debt; ● Repayment dependent upon the liquidation of collateral; ● Inability to perform as agreed, but adequately protected by collateral; ● Necessity to renegotiate payments to a non-standard level to ensure performance; and ● The borrower is bankrupt, or for any other reason, future repayment is dependent on court action. Doubtful loans have all the weaknesses inherent in loans classified as Substandard with the added characteristic that the weaknesses make collection or liquidation in full, based on currently existing facts, conditions, and value, highly questionable and improbable. Doubtful loans have a high probability of loss, yet certain important and reasonably specific pending factors may work toward the strengthening of the credit. Losses are recognized as charges to the allowance when the loan or portion of the loan is considered uncollectible or at the time of foreclosure. Recoveries on loans previously charged off are credited to the allowance for credit losses. Revolving loans that are converted to term loans are treated as new originations in the tables below and are presented by year of initial origination. During the three months ended March 31, 2024, and the year ended December 31, 2023, $129,000 and $7.1 million of revolving loans were converted to term loans, respectively.

Nonaccrual loans guaranteed by a government agency, which reduces the Company’s credit exposure, were $2.2 million at March 31, 2024 compared to $740,000 at December 31, 2023. At March 31, 2024, nonaccrual loans included $4.0 million of loans 30-89 days past due and $1.1 million of loans less than 30 days past due. At December 31, 2023, nonaccrual loans included $927,000 of loans 30-89 days past due and $2.1 million of loans less than 30 days past due. At March 31, 2024, the $4.0 million of nonaccrual loans 30-89 days past due was comprised of seven loans and the $1.1 million of loans less than 30 days past due was comprised of 14 loans. All these loans were placed on nonaccrual due to concerns over the financial condition of the borrowers. There were no loans that were 90 days or more past due and still accruing at March 31, 2024 and December 31, 2023. ​ Interest foregone on nonaccrual loans was approximately $483,000 for the three months ended March 31, 2024 compared to $235,000 for the three months ended March 31, 2023. Interest income recognized on nonaccrual loans was approximately $7,200 and $65,000 for the three months ended March 31, 2024 and 2023, respectively. ​ ​ Pledged Loans Our FHLB line of credit is secured under terms of a blanket collateral agreement by a pledge of certain qualifying loans with unpaid principal balances of $1.0 billion and $1.14 billion at March 31, 2024 and December 31, 2023, respectively.

Net charges-offs totaled $3.4 million during the first quarter of 2024, of which $3.2 million was specifically reserved for at December 31, 2023. No changes were made to the qualitative risk factor conclusions during the first quarter of 2024. The quantitative reserve was impacted by improvement in forecasted economic conditions, specifically, national unemployment levels and national gross domestic product, both of which are key indicators utilized to estimate credit losses. The reserve for individually evaluated loans decreased during the three months ended March 31, 2024 primarily due to a charge-off of $3.2 million of reserve ​ The following table summarizes the amortized cost basis of individually evaluated collateral-dependent loans, including nonaccrual loans, modified loans to borrowers experiencing financial difficulty, and accreting purchase credit deteriorated (“PCD”) loans that have experienced post-acquisition declines in cash flows expected to be collected, by loan and collateral type as of the dates indicated. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Retail and ​ ​ ​ Convalescent ​ ​ ​ ​ ​ ​ ​ A/R and ​ ​ ​ ​ ​ Office Multifamily facility Hotel Other ​ SFR 1-4 Equipment Total ACL March 31, 2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial and industrial $ — ​ $ — ​ $ — ​ $ — ​ $ 1,022 ​ $ — ​ $ 645 ​ $ 1,667 ​ $ 1,290 Construction and land ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ 366 ​ ​ — ​ ​ 366 ​ ​ — Commercial real estate ​ ​ 967 ​ 8,401 ​ 1,202 ​ 4,818 ​ 3,220 ​ — ​ — ​ 18,608 ​ 58 Residential ​ — ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ 1,463 ​ — ​ ​ 1,463 ​ 2 Consumer ​ — ​ — ​ — ​ — ​ — ​ — ​ — ​ — ​ — Total ​ $ 967 ​ $ 8,401 ​ $ 1,202 ​ $ 4,818 ​ $ 4,242 ​ $ 1,829 ​ $ 645 ​ $ 22,104 ​ $ 1,350 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2023 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial and industrial $ — ​ $ — ​ $ — ​ $ — ​ $ 1,021 ​ $ — ​ $ 1,052 ​ $ 2,073 ​ $ 1,423 Construction and land ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ 366 ​ ​ — ​ ​ 366 ​ ​ — Commercial real estate ​ ​ 224 ​ 5,305 ​ 2,213 ​ 135 ​ 1,165 ​ — ​ — ​ 9,042 ​ 3,008 Residential ​ — ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ 1,496 ​ — ​ ​ 1,496 ​ 2 Consumer ​ — ​ — ​ — ​ — ​ — ​ — ​ — ​ — ​ — Total ​ $ 224 ​ $ 5,305 ​ $ 2,213 ​ $ 135 ​ $ 2,186 ​ $ 1,862 ​ $ 1,052 ​ $ 12,977 ​ $ 4,433 ​ ​ The following table shows the amortized cost and allowance for credit losses for loans on nonaccrual status as of the dates indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of March 31, 2024 ​ As of December 31, 2023 ​ ​ Nonaccrual ​ Nonaccrual ​ ​ ​ Nonaccrual ​ Nonaccrual ​ ​ ​ ​ with no allowance ​ with allowance ​ Total ​ with no allowance ​ with allowance ​ Total ​ for credit losses for credit losses nonaccrual for loan losses for loan losses nonaccrual Commercial and industrial $ 103 ​ $ 1,564 ​ $ 1,667 ​ $ 272 ​ $ 1,800 ​ $ 2,072 Construction and land ​ ​ 366 ​ ​ — ​ ​ 366 ​ ​ 366 ​ ​ — ​ ​ 366 Commercial real estate ​ ​ 7,869 ​ 5,126 ​ ​ 12,995 ​ 1,295 ​ 7,748 ​ 9,043 Residential ​ 1,324 ​ 139 ​ ​ 1,463 ​ ​ 1,349 ​ ​ 147 ​ 1,496 Consumer ​ — ​ — ​ ​ — ​ — ​ — ​ — Total ​ $ 9,662 ​ $ 6,829 ​ $ 16,491 ​ $ 3,282 ​ $ 9,695 ​ $ 12,977 ​ ​ As part of the acquisition of Pacific Enterprise Bancorp (“PEB”) in 2022, the Company acquired certain small business loans to borrowers qualified under The California Capital Access Program for Small Business, a state guaranteed loan program sponsored by the California Pollution Control Financing Authority (“CalCAP”). PEB ceased originating loans under this loan program in 2017. Under this loan program, the borrower, CalCAP and the participating lender contributed funds to a loss reserve account that is held in a demand deposit account at the participating lender. The borrower contributions to the loss reserve account are attributed to the participating lender. Losses on qualified loans are charged to this account after approval by CalCAP. Under the program, if a loan defaults, the participating lender has immediate coverage of 100% of the loss. The participating lender must return recoveries from the borrower, less expenses, to the credit loss reserve account. The funds in the loss reserve account are the property of CalCAP; however, in the event that the participating lender leaves the program any excess funds, after all loans have been repaid or unenrolled from the program by the participating lender and provided there are no pending claims for reimbursement, the remaining excess funds are distributed to CalCAP and the participating lender based on their respective contributions to the loss reserve account. Funds contributed by the participating lender to the loss reserve account are treated as a receivable from CalCAP and evaluated for impairment quarterly. As of March 31, 2024 and December 31, 2023, the Company had $19.2 million and $19.4 million, respectively, of loans enrolled in this loan program. The Company had a loss reserve account of $13.7 million as of both March 31, 2024 and December 31, 2023. ​

LEASES	NOTE 7 – LEASES The Company leased 20 branches under noncancelable operating leases as of March 31, 2024. These leases expire on various dates through 2030. The Company’s leases often have an option to renew one or more times, at the Company’s discretion, following the expiration of the initial term. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. ​ The Company uses the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. ​ The below maturity schedule represents the undiscounted lease payments for the five-year period and thereafter as of March 31, 2024: ​ ​ ​ ​ ​ For remainder of 2024 ​ $ 2,921 2025 ​ ​ 3,436 2026 ​ 2,751 2027 ​ 2,322 2028 ​ ​ 2,164 Thereafter ​ 2,041 Total undiscounted cash flows ​ ​ 15,635 Less: interest ​ ​ (1,314) Present value of lease payments ​ $ 14,321 ​ The following table presents the weighted average lease term and discount rate at the dates indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2024 ​ December 31, 2023 Weighted-average remaining lease term 4.7 years ​ 4.8 years Weighted-average discount rate 3.6 % ​ 3.4 % ​ ​ The following table presents certain information related to the operating lease costs included in occupancy and equipment expense on the consolidated statements of income for the periods indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ March 31, ​ ​ 2024 ​ 2023 Operating lease cost ​ $ 986 ​ $ 955 Short-term lease cost ​ 15 ​ 44 Less: Sublease income ​ (12) ​ (22) Total operating lease cost, net ​ $ 989 ​ $ 977 ​

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND INTANGIBLE ASSETS	NOTE 8 – GOODWILL AND INTANGIBLE ASSETS Goodwill is determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and the liabilities assumed as of the acquisition date. Goodwill and other intangible assets are assessed for impairment annually or whenever events or changes in circumstances indicate the carrying amount may not be recoverable. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Core deposit intangible represents the estimated future benefit of deposits related to an acquisition and is booked separately from the related deposits and amortized over an estimated useful life of seven Goodwill The Company’s policy is to assess goodwill for impairment at the reporting unit level on an annual basis or between annual assessments if a triggering event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Impairment exists when a reporting unit’s fair value is less than its carrying amount, including goodwill. Changes in the Company's goodwill during the three months ended March 31, 2024 and year ended December 31, 2023 were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2024 ​ December 31, 2023 Balance at beginning of period ​ $ 38,838 ​ $ 38,838 Acquired goodwill ​ — ​ — Impairment ​ — ​ — Balance at end of period ​ $ 38,838 ​ $ 38,838 ​ Core Deposit Intangible Changes in the Company’s core deposit intangible during the three months ended March 31, 2024 and year ended December 31, 2023 were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2024 ​ December 31, 2023 Balance at beginning of period ​ $ 3,915 ​ $ 5,201 Additions ​ — ​ — Less amortization ​ (305) ​ (1,286) Balance at end of period ​ $ 3,610 ​ $ 3,915 ​ Estimated annual amortization expense at March 31, 2024 was as follows: ​ ​ ​ ​ ​ For remainder of 2024 ​ $ 917 2025 ​ ​ 948 2026 ​ 455 2027 ​ 455 2028 ​ ​ 455 Thereafter ​ 380 Total ​ $ 3,610 ​

The 2017 Plan provides for the awarding by the Company’s Board of Directors of equity incentive awards to employees and non-employee directors. An equity incentive award under the 2017 Plan may be an option, stock appreciation right, restricted stock units, stock award, other stock-based award or performance award. Factors considered by the Board in awarding equity incentives to officers and employees include the performance of the Company, the employee’s or officer’s job performance, the importance of his or her position, and his or her contribution to the organization’s goals for the award period. Generally, awards have a vesting period of no longer than ten years. Subject to adjustment as provided in the 2017 Plan, the maximum number of shares of common stock that may be delivered pursuant to awards granted under the 2017 Plan is 450,000 . The 2017 Plan provides for annual restricted stock grant limits to officers, employees and directors. The annual stock grant limit per person for officers and employees is the lesser of 50,000 shares or a value of $2.0 million, and per person for directors, the maximum is 25,000 shares. All unvested restricted shares outstanding vest in the event of a change in control of the Company.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	NOTE 15 – FAIR VALUE MEASUREMENT ASC Topic 820, “Fair Value Measurement,” defines fair value, establishes a framework for measuring fair value including a three-level valuation hierarchy, and expands disclosures about fair value measurements. Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date reflecting assumptions that a market participant would use when pricing an asset or liability. The hierarchy uses three levels of inputs to measure the fair value of assets and liabilities as follows: Level 1 Level 2 Level 3 We use fair value to measure certain assets and liabilities on a recurring basis, primarily securities AFS. For assets measured at the lower of cost or fair value, the fair value measurement criteria may or may not be met during a reporting period and such measurements are therefore considered “nonrecurring” for purposes of disclosing our fair value measurements. Fair value is used on a nonrecurring basis to adjust carrying values for individually evaluated loans and other real estate owned and to record impairment on certain assets, such as goodwill, core deposit intangible, and other long-lived assets. In certain cases, the inputs used to measure fair value may fall into different levels of the hierarchy. In such cases, the lowest level of inputs that is significant to the measurement is used to determine the hierarchy for the entire asset or liability. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincides with our quarterly valuation process. There were no transfers between levels during the three months ended March 31, 2024 and 2023. The following assets are measured at fair value on a recurring basis as of the dates indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Estimated Fair Value Measurements ​ ​ Fair Value ​ Level 1 ​ Level 2 ​ Level 3 March 31, 2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Municipal securities ​ $ 21,852 ​ $ — ​ $ 21,852 ​ $ — Mortgage-backed securities ​ 36,890 ​ — ​ 36,890 ​ — Collateralized mortgage obligations ​ 35,593 ​ — ​ 35,593 ​ — SBA securities ​ 4,912 ​ — ​ 4,912 ​ — Corporate bonds ​ 68,672 ​ — ​ 68,672 ​ — Equity securities ​ ​ 13,158 ​ ​ 13,158 ​ ​ — ​ ​ — Total ​ $ 181,077 ​ $ 13,158 ​ $ 167,919 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Estimated Fair Value Measurements ​ ​ Fair Value ​ Level 1 ​ Level 2 ​ Level 3 December 31, 2023 ​ ​ ​ ​ Municipal securities ​ $ 20,827 ​ $ — ​ $ 20,827 ​ $ — Mortgage-backed securities ​ 37,601 ​ — ​ 37,601 ​ — Collateralized mortgage obligations ​ 32,976 ​ — ​ 32,976 ​ — SBA securities ​ 5,252 ​ — ​ 5,252 ​ — Corporate bonds ​ 66,496 ​ — ​ 66,496 ​ — Equity securities ​ ​ 12,585 ​ ​ 12,585 ​ ​ — ​ ​ — Total ​ $ 175,737 ​ $ 12,585 ​ $ 163,152 ​ $ — ​ The following assets are measured at fair value on a nonrecurring basis as of the dates indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Estimated Fair Value Measurements ​ ​ Fair Value ​ Level 1 ​ Level 2 ​ Level 3 March 31, 2024 ​ ​ ​ ​ Individually evaluated loans ​ $ 22,104 ​ $ — ​ $ — ​ $ 22,104 Total ​ $ 22,104 ​ $ — ​ $ — ​ $ 22,104 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Estimated Fair Value Measurements ​ ​ Fair Value ​ Level 1 ​ Level 2 ​ Level 3 December 31, 2023 ​ ​ ​ ​ Individually evaluated loans (1) ​ $ 12,977 ​ $ — ​ $ — ​ $ 12,977 Total ​ $ 12,977 ​ $ — ​ $ — ​ $ 12,977 ​ (1) For each quarter the loan was outstanding in 2023, with the adoption of CECL, one performing modified loan to a borrower experiencing financial difficulty was individually evaluated in determining the estimated allowance for credit losses. The Company does not record loans at fair value on a recurring basis. However, from time to time, certain loans have individual risk characteristics not consistent with a pool of loans and are individually evaluated for credit reserves. Loans for which it is probable that payment of interest and principal will not be made in accordance with the original contractual terms of the loan agreement are typically individually evaluated. The fair value of individually evaluated loans is estimated using one of several methods, including collateral value, market value of similar debt, enterprise and liquidation value and discounted cash flows. Those individually evaluated loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. When the fair value of the collateral is based on an observable market price or a current appraised value which uses substantially observable data, the Company records the individually evaluated loan as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is less than the appraised value or the appraised The Company records foreclosed assets, or other real estate owned (“OREO”), at fair value on a nonrecurring basis based on the collateral value of the property. When the fair value of the collateral is based on an observable market price or a current appraised value which uses substantially observable data, the Company records the OREO as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is less than the appraised value or the appraised value contains a significant assumption, and there is no observable market price, the Company records the OREO as nonrecurring Level 3. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Management also incorporates assumptions regarding market trends or other relevant factors and selling and commission costs ranging from 5% to 10%. Such adjustments and assumptions are typically significant and result in a Level 3 classification of the inputs for determining fair value. The Company had no OREO at both March 31, 2024 and December 31, 2023.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 17 – COMMITMENTS AND CONTINGENCIES Lending and Letter of Credit Commitments We operate in a highly regulated environment. From time to time, we are a party to various claims and litigation matters incidental to the conduct of our business. We are not presently party to any legal proceedings where we believe the resolution would have a material adverse effect on our business, financial condition, or results of operations. Nevertheless, given the nature, scope and complexity of the extensive legal and regulatory landscape applicable to our business (including laws and regulations governing consumer protection, fair lending, fair labor, privacy, information security and anti-money laundering and anti-terrorism laws), we, like all banking organizations, are subject to heightened legal and regulatory compliance and litigation risk. In the normal course of business, the Company enters into various commitments to extend credit which are not reflected in the financial statements. These commitments consist of the undisbursed balance on home equity and unsecured personal lines of credit, commercial lines of credit, including commercial real estate secured lines of credit, and of undisbursed funds on construction and development loans. The Company also issues standby letter of credit commitments, primarily for the third-party performance obligations of clients. The following table presents a summary of commitments described above as of the dates indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, December 31, ​ ​ 2024 ​ 2023 Commitments to extend credit ​ $ 73,139 ​ $ 76,531 Standby letters of credit ​ 652 ​ 846 Total commitments ​ $ 73,791 ​ $ 77,377 ​ Commitments generally have fixed expiration dates or other termination clauses. The actual liquidity needs or the credit risk that the Company will experience will likely be lower than the contractual amount of commitments to extend credit because a significant portion of these commitments are expected to expire without being drawn upon. The commitments are generally variable rate and include unfunded home equity lines of credit, commercial real estate construction loans where disbursement is made over the course of construction, commercial revolving lines of credit, and unsecured personal lines of credit. The Company’s outstanding loan commitments are made using the same underwriting standards as comparable outstanding loans. The reserve associated with these commitments included in interest payable and other liabilities on the consolidated balance sheets was Commercial Real Estate Concentrations At March 31, 2024 and December 31, 2023, in management’s judgment, a concentration of loans existed in commercial real estate related loans. The Company’s commercial real estate loans are secured by owner-occupied and non-owner occupied commercial real estate and multifamily properties. Although management believes that loans within these concentrations have no more than the normal risk of collectability, a decline in the performance of the economy in general, or a decline in real estate values in the Company’s primary market areas in particular, could have an adverse impact on collectability Other Assets The Company has commitments to fund investments in LIHTC partnerships and an SBIC fund. At March 31, 2024, the remaining commitments to the LIHTC partnerships and the SBIC fund were approximately $5.4 million and $122,000, respectively. At December 31, 2023, the remaining commitments to the LIHTC partnerships and the SBIC fund were approximately $5.7 million and $122,000, respectively. Deposits At March 31, 2024, approximately $236.1 million, or 11.0%, of the Company's deposits were derived from its top ten depositors. At December 31, 2023, approximately $246.0 million, or 11.5%, of the Company's deposits were derived from its top ten depositors. As of March 31, 2024 and December 31, 2023, approximately $949.3 million, or 44.3% and $969.2 million, or 45.4%, of our total deposits were uninsured, respectively. The uninsured amounts are estimates based on the methodologies and assumptions used for United Business Bank’s regulatory reporting requirements. Local Agency Deposits and Other Advances In the normal course of business, the Company accepts deposits from local agencies. The Company is required to provide collateral for certain local agency deposits in the states of California, Colorado, New Mexico and Washington. As of both March 31, 2024 and December 31, 2023, the FHLB issued letters of credit on behalf of the Company totaling $40.6 million, as collateral for local agency deposits.
