Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies The accompanying unaudited consolidated financial statements include the accounts of First Seacoast Bancorp (the “Company”), its wholly-owned subsidiary, First Seacoast Bank (the “Bank”), and the Bank’s wholly-owned subsidiary, FSB Service Corporation, Inc. All significant intercompany balances and transactions have been eliminated in consolidation. Basis of Presentation The accompanying unaudited consolidated financial statements of the Company were prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim consolidated financial information, general practices within the banking industry and with instructions for Form 10-Q and Regulation S-X. Accordingly, these interim financial statements do not include all the information or footnotes required by U.S. GAAP for annual financial statements. However, in the opinion of management, all adjustments (consisting solely of normal recurring adjustments) necessary for a fair presentation of these consolidated financial statements have been included. The results of operations for the interim periods disclosed herein are not necessarily indicative of the results which may be expected for the entire year. These statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in the Annual Report on Form 10-K for the fiscal year ended December 31, 2021, as filed with the U.S. Securities and Exchange Commission (“SEC”) on March 25, 2022. Corporate Structure The Company is the federally-chartered holding company for the Bank (formerly named Federal Savings Bank). Effective July 16, 2019, pursuant to a Plan of Reorganization from Mutual Savings Bank to Mutual Holding Company and Stock Issuance Plan, the Bank reorganized into the mutual holding company structure, and the Company completed a concurrent stock offering. The Bank offers a full range of banking and wealth management services to its customers. The Bank focuses on four core services that center around customer needs. The core services include residential lending, commercial banking, personal banking and wealth management. The Bank offers a full range of commercial and consumer banking services through its network of five full-service branch locations. The Bank is engaged principally in the business of attracting deposits from the public and investing those funds in various types of loans, including residential and commercial real estate loans, and a variety of commercial and consumer loans. The Bank also invests its deposits and borrowed funds in investment securities. Deposits at the Bank are insured by the Federal Deposit Insurance Corporation (“FDIC”) for the maximum amount permitted by law. Banking services, the Company’s only reportable operating segment, is managed as a single strategic unit. Investment management services are offered through FSB Wealth Management. FSB Wealth management is a division of First Seacoast Bank. The division currently consists of two financial advisors who are located in Dover, New Hampshire. FSB wealth Management provides access to non-FDIC insured products that include retirement planning, portfolio management, investment and insurance strategies, business retirement plans and college planning to individuals throughout our primary market area. These investments and service are offered through a third-party registered broker-dealer and investment advisor. FSB Wealth Management receives fees from advisory services and commissions on individual investment and insurance products purchased by clients. The assets held for wealth management customers are not assets of the Company and, accordingly, are not reflected in the Company’s consolidated balance sheets. On August 17, 2021, the Bank entered into a definitive agreement with an investment advisory and wealth management firm (the “seller”) to purchase certain of its client accounts and client relationships for a purchase price of $347,000 (included in other assets at March 31, 2022 and December 31, 2021 net of accumulated amortization), of which $172,000 was paid at closing. Each client account has been assigned a value, and as each client transfers to the Bank, 85% of this value will be paid to the seller. By May 31, 2022, or upon mutual agreement that the transition of client accounts is complete, whichever is earlier, the balance of the purchase price will be paid to the seller. As of March 31, 2022, approximately $23.5 million of purchased client accounts are included in total assets under management. Assets under management totaled approximately $90.9 million and $88.0 million at March 31, 2022 and December 31, 2021, respectively. The client accounts purchased are recorded as a customer list intangible asset. Identifiable intangible assets that are subject to amortization will be reviewed for impairment, at least annually, based on their fair value. Any impairment will be recognized as a charge to earnings and the adjusted carrying amount of the intangible asset will become its new accounting basis. The remaining useful life of the intangible asset will also be evaluated each reporting period to determine whether events and circumstances warrant a revision to the remaining period of amortization. The Company is amortizing the customer list intangible on a straight-line basis over a ten year period. During the three months ended March 31, 2022 and 2021, $9,000 and $-0- of amortization expense was recorded in other expense, respectively. Recently Adopted Accounting Standards As an “emerging growth company,” as defined in Title 1 of Jumpstart Our Business Startups (JOBS) Act, the Company has elected to use the extended transition period to delay adoption of new or reissued accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. As a result, the Company’s consolidated financial statements may not be comparable to the financial statements of public companies that comply with such new or revised accounting standards without an extended transition period. As of March 31, 2022, there was no significant difference in the comparability of the Company’s consolidated financial statements as a result of this extended transition period except for the accounting treatment for measuring and recording the Company’s allowance for loan losses. The Company measures and records an allowance for loan losses based upon the incurred loss model while other public companies may be required to calculate their allowance for loan losses based upon the current expected credit loss (“CECL”) model. As a smaller reporting company the planned implementation of the CECL model is January 1, 2023. The CECL approach requires an estimate of the loan loss expected over the life of the loan, while the incurred loss approach delays the recognition of a loan loss until it is probable a loss event has occurred. The Company’s status as an “emerging growth company” will end on the earlier of: (i) the last day of the fiscal year of the Company during which it had total annual gross revenues of $1.07 billion (as adjusted for inflation) or more; (ii) the last day of the fiscal year of the Company following the fifth anniversary of the effective date of the Company’s initial public offering; (which will be December 31, 2024 for the Company) (iii) the date on which the Company has, during the previous three-year period, issued more than $1.0 billion in non-convertible debt; or (iv) the date on which the Company is deemed to be a “large accelerated filer” under Securities and Exchange Commission regulations (generally, at least $700 million of voting and non-voting equity held by non-affiliates). In January 2020, the FASB issued ASU 2020-1, “Investments – Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) – Clarifying the Interactions Between Topic 321, Topic 323, and Topic 815 (A Consensus of the Emerging Issues Task Force),” In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” In February 2016, the FASB issued ASU 2016-02, “ Leases (Topic 842). Codification Improvements to Topic 842, Leases “Targeted Improvements,” Recent Accounting Pronouncements Yet to Be Adopted The Company considers the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either not applicable or are expected to have an immaterial impact on the Company’s consolidated financial statements. In March 2022, the FASB issued ASU 2022-2, “Financial Instruments-Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures,” which eliminates the troubled debt restructuring (“TDR”) accounting model for creditors that have adopted Topic 326, “Financial Instruments – Credit Losses.” “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” In January 2021, the FASB issued ASU 2021-1, “Reference Rate Reform (Topic 848) (Scope),” In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848),” In February 2020, the FASB issued ASU 2020-2, “Financial Instruments – Credit Losses (Topic 326) and Leases (Topic 842) - Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section on Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842).” In November 2019, the FASB issued ASU 2019-11, “Codification Improvements to Topic 326, Financial Instruments – Credit Losses,” “Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates,” “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” “Leases (Topic 842),” In April 2019, the FASB issued ASU 2019-04, “Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments,” “Financial Instruments—Credit Losses, Topic 326.” In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which creates a new credit impairment standard for financial assets measured at amortized cost and available-for-sale debt securities. The ASU requires financial assets measured at amortized cost (including loans and held-to-maturity debt securities) to be presented at the net amount expected to be collected, through an allowance for credit losses that are expected to occur over the remaining life of the asset, rather than incurred losses. The ASU requires that credit losses on available-for-sale debt securities be presented as an allowance rather than as a direct write-down. The measurement of credit losses for newly recognized financial assets (other than certain purchased assets) and subsequent changes in the allowance for credit losses are recorded in the statement of income as the amounts expected to be collected change. The ASU was originally to be effective for fiscal years beginning after December 15, 2020 and interim periods within fiscal years beginning after December 15, 202 1 . In November 2018, the FASB issued ASU 2018-19, “Codification Improvements to Topic 326, Financial Instruments-Credit Losses,” extending the implementation date by one year for smaller reporting companies and clarifying that operating lease receivables are outside the scope of Accounting. On October 16, 2019, the FASB approved a proposal to delay the implementation of this standard for smaller reporting companies to years beginning after December 15, 2022. Early adoption is permitted. Upon adoption, however, the Company will apply the standard’s provisions as a cumulative effect adjustment to equity capital as of the first reporting period in which the guidance is effective. Upon adoption, the Company expects a change in the processes and procedures to calculate the allowance for loan losses, including changes in the assumptions and estimates to consider expected credit losses over the life of the loan versus the current accounting practice that utilizes the incurred loss model. The Company is reviewing the requirements of ASU 2016-13 and is developing and implementing processes and procedures to ensure it is fully compliant with the amendments at the adoption date. At this time, the Company anticipates the allowance for loan losses will increase as a result of the implementation of this ASU; however, until its evaluation is complete, the magnitude of the increase will be unknown .

In general, management concluded the declines are due to coupon rates compared to market rates and current economic conditions. The Company does not intend to sell investments with unrealized losses as it is more likely than not that the Company will not be required to sell these investments before recovery of their amortized cost basis. Based on evaluations of the underlying issuers’ financial condition, current trends and economic conditions, management does not believe any securities suffered an other-than-temporary decline in value as of March 31, 2022 . Proceeds from sales, maturities, principal payments received and gross realized gains and losses on available-for-sale securities were as follows for the three months ended: March 31, 2022 2021 (Dollars in thousands) Proceeds from sales, maturities and principal payments received on securities available-for-sale $ 1,796 $ 9,746 Gross realized gains 52 203 Gross realized losses — — Net realized gains $ 52 $ 203 At March 31, 2022 there were no holdings of securities of any issuer, other than the SBA, FHLMC and FNMA, whose aggregate carrying value exceeded 10% of stockholders’ equity.

Receivables [Abstract]
Loans	3 . Loans The Bank’s lending activities are primarily conducted in and around Dover, New Hampshire and in the areas surrounding its branches. The Bank grants commercial real estate loans, multifamily 5+ dwelling unit loans, commercial and industrial loans, acquisition, development and land loans, one- to four-family residential loans, home equity loans and lines of credit and consumer loans. Most loans originated by the bank are collateralized by real estate. The ability and willingness of real estate, commercial and construction loan borrowers to honor their repayment commitments is generally dependent on the health of the real estate sector in the borrowers’ geographic area and the general economy. In response to the COVID-19 pandemic, the Small Business Administration (“SBA”) established the Paycheck Protection Program (“PPP”), which was designed to aid small- and medium-sized businesses through federally guaranteed SBA loans (“PPP loans”) distributed through banks. PPP loans are fully guaranteed as to principal and interest by the SBA. During the year ended December 31, 2021, the Bank originated 134 PPP loans with aggregate outstanding principal balances of $13.1 million. As of March 31, 2022 and December 31, 2021, total PPP loan principal balances were $3.2 million and $5.5 million, respectively, and are included in commercial and industrial loans (C+I).

At December 31, 2021, this loan had a balance of $195,000 which was determined through a calculation of the present value of estimated future cashflows. At March 31, 2022, the balance of this TDR was approximately $194,000. The modification agreement defers delinquent interest and escrow payments to the end of the loan. The allowance for loan losses included a specific reserve for this TDR of $-0- at March 31, 2022 and December 31, 2021. At March 31, 2021, there were no loans modified as TDRs. Credit Quality Information The Bank utilizes a ten-grade internal loan rating system for its commercial real estate, multifamily, commercial and industrial and acquisition, development and land loans. Residential real estate, home equity line of credit and consumer loans are considered “pass” rated loans until they become delinquent. Once delinquent, loans can be rated an 8, 9 or 10 as applicable. Loans rated 1 through 6: Loans in these categories are considered “pass” rated loans with low to average risk. Loans rated 7: Loans in this category are considered “special mention.” These loans are starting to show signs of potential weakness and are being closely monitored by management. Loans rated 8: Loans in this category are considered “substandard.” Generally, a loan is considered substandard if it is inadequately protected by the current net worth and paying capacity of the obligors and/or the collateral pledged. There is a distinct possibility that the Bank will sustain some loss if the weakness is not corrected. These loans are individually evaluated for impairment on a quarterly basis, or more often if needed. Loans rated 9: Loans in this category are considered “doubtful.” Loans classified as doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable. Loans rated 10: Loans in this category are considered uncollectible (“loss”) and of such little value that their continuance as loans is not warranted and should be charged off. On an annual basis, or more often if needed, the Bank formally reviews the ratings on its commercial and industrial, commercial real estate and multifamily loans. On a periodic basis, the Bank engages an independent third party to review a significant portion of loans within these segments and to assess the credit risk management practices of its commercial lending department. Management uses the results of these reviews as part of its annual review process and overall credit risk administration. On a quarterly basis, the Bank formally reviews the ratings on its applicable residential real estate and home equity loans if they have become classified as non-accrual. Criteria used to determine ratings consist of loan-to-value ratios and days delinquent. The following presents the internal risk rating of loans by portfolio segment as of March 31, 2022: (Dollars in thousands) Pass Special Mention Substandard Total CRE $ 73,619 $ 2,677 $ 101 $ 76,397 MF 8,900 — — 8,900 C+I 28,434 — 25 28,459 ADL 17,423 — — 17,423 RES 234,593 — 680 235,273 HELOC 6,454 — 115 6,569 CON 4,988 — — 4,988 Total $ 374,411 $ 2,677 $ 921 $ 378,009 The following presents the internal risk rating of loans by portfolio segment as of December 31, 2021: (Dollars in thousands) Pass Special Mention Substandard Total CRE $ 69,252 $ 2,701 $ 104 $ 72,057 MF 8,998 — — 8,998 C+I 26,823 — 28 26,851 ADL 21,365 — — 21,365 RES 233,477 — 722 234,199 HELOC 6,832 — 115 6,947 CON 4,574 — — 4,574 Total $ 371,321 $ 2,701 $ 969 $ 374,991 Certain directors and executive officers of the Company and companies in which they have significant ownership interests were customers of the Bank.

The unpaid principal balances of such loans were $38.4 million and $40.6 million at March 31, 2022 and December 31, 2021, respectively. Substantially all of these loans were originated by the Bank and sold to third parties on a non-recourse basis with servicing rights retained. These retained servicing rights are recorded as a servicing asset and are initially recorded at fair value (see Note 14, Fair Value of Assets and Liabilities, for more information). Changes to the balance of mortgage servicing rights are recorded in loan servicing fee income in the Company’s consolidated statements of income. The Bank’s mortgage servicing activities include: collecting principal, interest and escrow payments from borrowers; making tax and insurance payments on behalf of borrowers; monitoring delinquencies and executing foreclosure proceedings; and accounting for and remitting principal and interest payments to investors. Loan servicing fee income, including late and ancillary fees, was $52,000 and $83,000 for the three months ended March 31, 2022 and 2021, respectively. Servicing fee income is recorded in loan servicing fee income in the Company’s consolidated statements of income. The Bank’s residential mortgage investor loan servicing portfolio is primarily comprised of fixed rate loans secured by properties located in the Bank’s market area.

The recorded liability at March 31, 2022 and December 31, 2021 relating to this supplemental executive benefit agreement was $35,000. The expense of this supplemental plan was $-0- for the three months ended March 31, 2022 and 2021. Directors Deferred Supplemental Retirement Plan The Company has a supplemental retirement plan for eligible directors that provides for monthly benefits based upon years of service to the Company, subject to certain limitations as set forth in the agreements. The present value of these future payments is being accrued over the estimated period of service. The estimated liability at March 31, 2022 and December 31, 2021 relating to this plan was $508,000 and $550,000, respectively. The discount rate used to determine the Company’s obligation was 6.25% at March 31, 2022 and December 31, 2021. Total supplemental retirement plan expense amounted to $19,000 and $17,000 for the three months ended March 31, 2022 and 2021, respectively. The Company enacted a “hard freeze” for this supplemental retirement plan as of January 1, 2022. On February 10, 2022, the Bank and the non-employee members of the board of directors of the Bank entered into amendments to the Supplemental Director Retirement Agreements (the “Agreements”) previously entered into by the Bank and the directors. The amendments eliminate the formula for determining the normal annual retirement benefit (previously “ 70 % of Final Base Fee”) and replaces it with a fixed annual benefit of $ 20,000 . The amendments also eliminate the formula for determining the benefit payable on a change in control (previously tied to the normal annual retirement formula with certain imputed increases in the Base Fee) and replacing it with a fixed amount equal to the present value of $ 200,000 . The effect of the amendments is to eliminate the variable and increasing costs associated with the Agreements. Instead, since the normal annual retirement benefit will be a fixed amount, the future costs associated with the Agreements is now more predictable. It is the intention of the Bank that no new directors of the Bank would enter into similar agreements. Additionally, the Company has a deferred director’s fee plan, which allows members of the board of directors to defer the receipt of fees that otherwise would be paid to them. At March 31, 2022 and December 31, 2021, the total deferred director’s fees amounted to $424,000 and $420,000, respectively.

Stock Based Compensation	8 . Stock Based Compensation Employee Stock Ownership Plan The Company maintains the First Seacoast Bank Employee Stock Ownership Plan (“ESOP”) to provide eligible employees of the Company the opportunity to own Company stock. The ESOP is a tax-qualified retirement plan for the benefit of Company employees. Contributions are allocated to eligible participants on the basis of compensation, subject to federal limits. The number of shares committed to be released per year through 2038 is 11,924. The ESOP funded its purchase of 238,473 shares through a loan from the Company equal to 100% of the aggregate purchase price of the common stock. The ESOP trustee is repaying the loan principally through the Bank’s contributions to the ESOP over the remaining loan term that matures on December 31, 2038. At March 31, 2022 and December 31, 2021, the remaining principal balance on the ESOP debt was $2.1 million. Under applicable accounting requirements, the Company records compensation expense for the ESOP equal to fair market value of shares when they are committed to be released from the suspense account to participants’ accounts under the plan. Total compensation expense recognized in connection with the ESOP for the three months ended March 31, 2022 and 2021 was $31,000 and $28,000, respectively. At March 31, 2022 and December 31, 2021, total unearned compensation for the ESOP was $2.0 million. March 31, 2022 December 31, 2021 Shares held by the ESOP include the following: Allocated 35,772 23,848 Committed to be allocated 2,981 11,924 Unallocated 199,720 202,701 Total 238,473 238,473 The fair value of unallocated shares was approximately $2.1 million and $2.2 million at March 31, 2022 and December 31, 2021, respectively. Equity Incentive Plan Effective May 27, 2021, the Company adopted the First Seacoast Bancorp 2021 Equity Incentive Plan (the “2021 Plan”). The Company’s stockholders approved the 2021 plan on that date. The 2021 Plan provides for the granting of incentive and non-statutory stock options to purchase shares of common stock and the granting of shares of restricted stock awards and restricted stock units. The 2021 Plan authorizes the issuance or delivery to participants of up to 417,327 shares of common stock. Of this number, the maximum number of shares of common stock that may be issued pursuant to the exercise of stock options is 298,091 shares and the maximum number of shares of common stock that may be issued as restricted stock awards or restricted stock units is 119,236 shares. The exercise price of stock options may not be less than the fair market value on the date the stock option is granted. Further, stock options may not be granted with a term that is longer than 10 years. As of March 31, 2022, no stock options have been granted. On November 18, 2021, 118,270 restricted stock awards were granted to directors and certain members of management at $ 9.99 per share. The total fair value related to the November 18, 2021 grant was $ 1.2 million. Restricted stock awards time-vest over a three year period and have been fair valued as of the date of grant. The holders of restricted stock awards participate fully in the rewards of stock ownership of the Company, including voting rights when granted and dividend rights when vested. A summary of non-vested restricted shares outstanding as of March 31, 2022 and changes during the three months ended is presented below : March 31, 2022 Number of Shares Weighted Average Grant Value Restricted stock: Non-vested at beginning of period 118,270 $ 9.99 Granted — — Vested — — Forfeited — — Non-vested at end of period 118,270 $ 9.99 For the three months ended March 31, 2022, the expense recognized for this equity incentive plan was $99,000 which provided a tax benefit of $27,000. At March 31, 2022 and December 31, 2021, total unrecognized compensation expense for this equity incentive plan was $1.0 million and $1.1 million, respectively, with a 2.6 and 2.9 year weighted average future recognition period, respectively.

These agreements are accounted for as operating leases and their terms expire between 2022 and 2025 and, in some instances, contain options to renew for periods up to four years. The Company has no financing leases. The Company adopted ASU 2016-02 – Leases (Topic 842) The following table summarizes information related to the Company’s right-of-use asset and net lease liability: March 31, 2022 Operating Leases Balance Sheet Location (Dollars in thousands) Right-of-use asset $ 65 Other Assets Net lease liability 65 Other Liabilities The Company determines whether a contract contains a lease based on whether a contract, or a part of a contract, conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The discount rate is either implicit in the lease or, when a rate cannot be readily determined, the Company’s incremental borrowing rate is used. The incremental borrowing rate is the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term. The components of operating lease cost and other related information are as follows : The three months ended March 31, 2022 (Dollars in thousands) Operating lease cost $ 12 Short-term lease cost — Variable lease cost (Cost excluded from lease payments) — Sublease income — Total operating lease cost 12 Other Information: Cash paid for amounts included in the measurement of lease liabilities - operating cash flows from operating leases 12 Operating lease - operating cash flows (liability reduction) $ — Weighted average lease term 2.0 years Weighted average discount rate 2.46 % The total minimum lease payments due in future periods for lease agreements in effect at March 31, 2022 were as follows: The three months ended March 31, 2022 Future Minimum Lease Payments (Dollars in thousands) Remainder of 2022 $ 37 2023 16 2024 10 2025 4 2026 — Thereafter — Total minimum lease payments 67 Less: interest (2 ) Total lease liability 65 One of the Company’s lease agreements contain clauses calling for escalation of minimum lease payments contingent on increases in LIBOR, or a similar replacement index, and the consumer price index.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	1 3 . Derivatives and Hedging Activities Derivatives are recognized as either assets or liabilities on the balance sheet and are measured at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and resulting designation. The Company utilizes interest rate swap agreements as part of its asset liability management strategy. Interest rate swaps involve the exchange of interest payments at specified intervals between two parties without the exchange of any underlying principal. These derivative instruments are designated as cash flow hedges with changes in the fair value of the derivative recorded in accumulated other comprehensive (loss) income and recognized in earnings when the hedged transaction affects earnings. The hedges were determined to be effective and the Company expects the hedges to remain effective during the remaining terms of the swaps. The Company entered into two $5 million notional interest rate swaps that have been designated as cash flow hedges on 90-day advances from FHLB. The purpose of these cash flow hedges is to reduce potential interest rate risk by swapping a variable rate borrowing to a fixed rate. Management deemed it prudent to limit the variability of these interest payments by entering into these interest rate swap agreements. These agreements provide for the Company to receive payments at a variable rate determined by a specific index (three-month LIBOR) in exchange for making payments at a fixed rate. Publication of LIBOR is expected to cease in June of 2023. The swap agreements allow for substitution of an alternative reference rate such as the secured overnight financing rate (“SOFR”) at that time. The changes in the fair value of interest rate swaps are reported in other comprehensive (loss) income and are subsequently reclassified into interest expense in the period that the hedged transactions affect earnings. During the next twelve months, the Company estimates that an additional $60,000 will be reclassified as an increase to interest expense. For the three months ended March 31, 2022 and 2021, the change in fair value for these derivative instruments was $435,000 and $241,000, respectively. At March 31, 2022 and December 31, 2021, the fair value of interest rate swap derivatives resulted in an asset of $635,000 and $200,000, respectively, and is recorded in other assets. The following table summarizes the Company’s derivatives associated with its interest rate risk management activities: March 31, 2022 (Dollars in thousands) Start Date Maturity Date Rate Notional Assets Liabilities Debt Hedging Hedging Instruments: Interest Rate Swap 2020 4/13/2020 4/13/2025 0.68% $ 5,000 $ 283 $ — Interest Rate Swap 2021 4/13/2021 4/13/2026 0.74% 5,000 352 — Total Hedging Instruments $ 10,000 $ 635 $ — Hedged Items: Variability in cash flows related to 90-day FHLB advances N/A $ — $ 10,000 December 31, 2021 (Dollars in thousands) Start Date Maturity Date Rate Notional Assets Liabilities Debt Hedging Hedging Instruments: Interest Rate Swap 2020 4/13/2020 4/13/2025 0.68% $ 5,000 $ 85 $ — Interest Rate Swap 2021 4/13/2021 4/13/2026 0.74% 5,000 115 — Total Hedging Instruments $ 10,000 $ 200 $ — Hedged Items: Variability in cash flows related to 90-day FHLB advances N/A $ — $ 10,000 The following table summarizes the effect of cash flow hedge accounting on the consolidated statements of income for the three months ended March 31, 2022 and 2021: Location and Amount of Loss Recognized in Consolidated Statements of Income 2022 2021 (Dollars in thousands) Interest Income (Expense) Other Income (Expense) Interest Income (Expense) Other Income (Expense) The effect of cash flow hedge accounting: Amount reclassified from AOCI into expense $ (12 ) $ — $ (5 ) $ — The credit risk associated with these interest rate swaps is the risk of default by the counterparty. To minimize this risk, the Company only enters into interest rate swaps agreements with highly rated counterparties that management believes to be creditworthy. The notional amounts of these agreements do not represent amounts exchanged by the parties and, therefore, are not a measure of the potential loss exposure. Risk management results for the three months ended March 31, 2022, related to the balance sheet hedging of $10.0 million of 90 day FHLB advances, included in borrowings, indicate that the hedge was 100% effective and there was no component of the derivative instruments’ unrealized gain which was excluded from the assessment of hedge effectiveness. At March 31, 2022 and December 31, 2021, the Company posted $526,000, of cash to the counterparty as collateral on its interest rate swap contracts which was presented within cash and due from banks on the consolidated balance sheets.

Disclosure Of Fair Values Of Assets And Liabilities [Abstract]
Fair Values of Assets and Liabilities	1 4 . Fair Values of Assets and Liabilities Determination of Fair Value The fair value of an asset or liability is the 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. The Company uses prices and inputs that are current as of the measurement date, including during periods of market dislocation. In periods of market dislocation, the observability of prices and inputs may be reduced for many instruments. This condition could cause an instrument to be reclassified from one level to another. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various assets and liabilities. In cases where quoted market prices are not available, fair values are based on estimates using present value of cash flows or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. The Company groups its assets and liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the observability and reliability of the assumptions used to determine fair value. Level 1 - Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 - Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 - Level 3 inputs are unobservable inputs for the asset or liability. For assets and liabilities, fair value is based upon the lowest level of observable input that is significant to the fair value measurement. In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon models that primarily use, as inputs, observable market-based parameters. The Company ’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company ’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Furthermore, the reported fair value amounts have not been comprehensively revalued since the presentation dates, and therefore, estimates of fair value after the balance sheet date may differ significantly from the amounts presented herein. A more detailed description of the valuation methodologies used for assets and liabilities measured at fair value is set forth below. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to all the Company ’s financial assets and financial liabilities carried at fair value at March 31, 2022 and December 31, 2021 . Financial Assets and Financial Liabilities: Financial assets and financial liabilities measured at fair value on a recurring basis include the following: Securities Available-for-Sale : The Company’s investment in U.S. Government-sponsored entities bonds, U.S Government agency small business administration pools guaranteed by the SBA, collateralized mortgage obligations issued by the FHLMC, FNMA and GNMA residential mortgage-backed securities, other municipal bonds and corporate subordinated debt is generally classified within Level 2 of the fair value hierarchy. For these securities, the Company obtains fair value measurements from independent pricing services or uses fair value measurements considering observable market data. The fair value measurements consider observable data that may include reported trades, dealer quotes, market spreads, cash flows, the U.S. treasury yield curve, trading levels, market consensus prepayment speeds, credit information and the instrument’s terms and conditions. Mortgage Servicing Rights : Fair value is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model utilizes interest rate, prepayment speed and default rate assumptions that market participants would use in estimating future net servicing income and that can be validated against available market data (see Note 4 Loan Servicing for more information). These assumptions are inherently sensitive to change as these unobservable inputs are not based on quoted prices in active markets or otherwise observable. Derivative Instruments and Hedges: The valuation of these instruments is determined using the discounted cash flow method on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The following table summarizes financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2022 and December 31, 2021, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value: Total Level 1 Level 2 Level 3 (Dollars in thousands) March 31, 2022 Securities available-for-sale: U.S. Government-sponsored enterprises obligations $ 6,087 $ — $ 6,087 $ — U.S Government agency small business administration pools guaranteed by the SBA 7,272 — 7,272 — Collateralized mortgage obligations issued by the FHLMC, FNMA and GNMA 3,947 — 3,947 — Residential mortgage-backed-securities 23,620 — 23,620 — Municipal bonds 53,642 — 53,642 — Corporate subordinated debt 3,922 — 3,922 — Other assets: Mortgage servicing rights 350 — — 350 Derivatives 635 — 635 — Total Level 1 Level 2 Level 3 (Dollars in thousands) December 31, 2021 Securities available-for-sale: U.S. Government-sponsored enterprises obligations $ 5,971 $ — $ 5,971 $ — U.S Government agency small business administration pools guaranteed by the SBA 5,045 — 5,045 — Collateralized mortgage obligations issued by the FHLMC, FNMA and GNMA 3,332 — 3,332 — Residential mortgage-backed-securities 23,332 — 23,332 — Municipal bonds 50,613 — 50,613 — Corporate subordinated debt 3,072 — 3,072 — Other assets: Mortgage servicing rights 322 — — 322 Derivatives 200 — 200 — For the three months ended March 31, 2022 and 2021, the changes in Level 3 assets and liabilities measured at fair value on a recurring basis were as follows: (Dollars in thousands) Mortgage Servicing Rights (1) Balance as of January 1, 2022 $ 322 Included in net income 28 Balance as of March 31, 2022 $ 350 Total unrealized net gains (losses) included in net income related to assets still held as of March 31, 2022 $ — Balance as of January 1, 2021 $ 273 Included in net income 56 Balance as of March 31, 2021 $ 329 Total unrealized net gains (losses) included in net income related to assets still held as of March 31, 2021 $ — (1) Realized and unrealized gains and losses related to mortgage servicing rights are reported as a component of loan servicing fee income in the Company’s consolidated statements of income. For Level 3 assets measured at fair value on a recurring basis as of March 31, 2022 and December 31, 2021, the significant unobservable inputs used in the fair value measurements were as follows: March 31, 2022 (Dollars in thousands) Valuation Technique Description Range Weighted Average (1) Fair Value Mortgage Servicing Rights Discounted Cash Flow Prepayment Rate 6.81% - 24.78% 10.10% $ 350 Discount Rate 9.00% - 9.00% 9.00% Delinquency Rate 2.73% - 3.61% 2.88% Default Rate 0.08% - 0.14% 0.13% December 31, 2021 (Dollars in thousands) Valuation Technique Description Range Weighted Average (1) Fair Value Mortgage Servicing Rights Discounted Cash Flow Prepayment Rate 6.63% - 25.56% 13.39% $ 322 Discount Rate 9.00% - 9.00% 9.00% Delinquency Rate 2.82% - 3.63% 2.96% Default Rate 0.08% - 0.14% 0.13% (1) Unobservable inputs for mortgage servicing rights were weighted by loan amount. The significant unobservable inputs used in the fair value measurement of the Company’s mortgage servicing rights are the weighted-average prepayment rate, weighted-average discount rate, weighted average delinquency rate and weighted-average default rate. Significant increases (decreases) in any of those inputs in isolation could result in a significantly lower (higher) fair value measurement. Although the prepayment rate and the discount rate are not directly interrelated, they generally move in opposite directions of each other. The Company estimates the fair value of mortgage servicing rights by using a discounted cash flow model to calculate the present value of estimated future net servicing income. Observable and unobservable inputs are entered into this model as prescribed by an independent third party to arrive at an estimated fair value. See Note 4, Loan Servicing, for a rollforward of our Level 3 item and related inputs and assumptions used to determine fair value at March 31, 2022. Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Financial assets measured at fair value on a non-recurring basis during the reported periods may include certain impaired loans reported at the fair value of the underlying collateral. Fair value is measured using appraised values of collateral and adjusted as necessary by management based on unobservable inputs for specific properties. However, the choice of observable data is subject to significant judgment, and there are often adjustments based on judgment in order to make observable data comparable and to consider the impact of time, the condition of properties, interest rates and other market factors on current values. Additionally, commercial real estate appraisals frequently involve discounting of projected cash flows, which relies inherently on unobservable data. Therefore, real estate collateral-related non-recurring fair value measurement adjustments have generally been classified as Level 3. Estimates of fair value used for other collateral supporting commercial loans generally are based on assumptions not observable in the marketplace and therefore such valuations have been classified as Level 3. Financial Non-Financial Assets and Non-Financial Liabilities: The Company has no non-financial assets or non-financial liabilities measured at fair value on a recurring basis. Non-financial assets measured at fair value on a non-recurring basis generally include certain foreclosed assets which, upon initial recognition, were remeasured and reported at fair value through a charge-off to the allowance for loan losses and certain foreclosed assets which, subsequent to their initial recognition, are remeasured at fair value through a write-down included in other non-interest expense. There were no foreclosed assets at March 31, 2022 or December 31, 2021. ASC Topic 825, “Financial Instruments,” Summary of Fair Values of Financial Instruments not Carried at Fair Value The estimated fair values, and related carrying or notional amounts, of the Company’s financial instruments at March 31, 2022 and December 31, 2021 are as follows: (Dollars in thousands) Carrying Amount Fair Value Level 1 Level 2 Level 3 March 31, 2022 Financial Assets: Cash and due from banks $ 5,493 $ 5,493 $ 5,493 $ — $ — Interest-bearing time deposits with other banks 1,245 1,245 — 1,245 — Federal Home Loan Bank stock 2,410 2,410 — 2,410 — Bank-owned life insurance 4,481 4,481 — 4,481 — Loans, net 376,181 361,941 — — 361,941 Accrued interest receivable 1,568 1,568 1,568 — — Financial Liabilities: Deposits $ 388,769 $ 387,605 $ 332,029 $ 55,576 $ — Advances from Federal Home Loan Bank 49,700 48,581 — 48,581 — Mortgagors’ tax escrow 1,898 1,898 — 1,898 — December 31, 2021 Financial Assets: Cash and due from banks $ 6,638 $ 6,638 $ 6,638 $ — $ — Interest-bearing time deposits with other banks 1,245 1,245 — 1,245 — Federal Home Loan Bank stock 1,688 1,688 — 1,688 — Bank-owned life insurance 4,461 4,461 — 4,461 — Loans, net 373,051 371,587 — — 371,587 Accrued interest receivable 1,499 1,499 1,499 — — Financial Liabilities: Deposits $ 393,243 $ 393,145 $ 334,917 $ 58,228 $ — Advances from Federal Home Loan Bank 29,462 29,063 — 29,063 — Mortgagors’ tax escrow 652 652 — 652 —

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements of the Company were prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim consolidated financial information, general practices within the banking industry and with instructions for Form 10-Q and Regulation S-X. Accordingly, these interim financial statements do not include all the information or footnotes required by U.S. GAAP for annual financial statements. However, in the opinion of management, all adjustments (consisting solely of normal recurring adjustments) necessary for a fair presentation of these consolidated financial statements have been included. The results of operations for the interim periods disclosed herein are not necessarily indicative of the results which may be expected for the entire year. These statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in the Annual Report on Form 10-K for the fiscal year ended December 31, 2021, as filed with the U.S. Securities and Exchange Commission (“SEC”) on March 25, 2022.
Corporate Structure	Corporate Structure The Company is the federally-chartered holding company for the Bank (formerly named Federal Savings Bank). Effective July 16, 2019, pursuant to a Plan of Reorganization from Mutual Savings Bank to Mutual Holding Company and Stock Issuance Plan, the Bank reorganized into the mutual holding company structure, and the Company completed a concurrent stock offering. The Bank offers a full range of banking and wealth management services to its customers. The Bank focuses on four core services that center around customer needs. The core services include residential lending, commercial banking, personal banking and wealth management. The Bank offers a full range of commercial and consumer banking services through its network of five full-service branch locations. The Bank is engaged principally in the business of attracting deposits from the public and investing those funds in various types of loans, including residential and commercial real estate loans, and a variety of commercial and consumer loans. The Bank also invests its deposits and borrowed funds in investment securities. Deposits at the Bank are insured by the Federal Deposit Insurance Corporation (“FDIC”) for the maximum amount permitted by law. Banking services, the Company’s only reportable operating segment, is managed as a single strategic unit. Investment management services are offered through FSB Wealth Management. FSB Wealth management is a division of First Seacoast Bank. The division currently consists of two financial advisors who are located in Dover, New Hampshire. FSB wealth Management provides access to non-FDIC insured products that include retirement planning, portfolio management, investment and insurance strategies, business retirement plans and college planning to individuals throughout our primary market area. These investments and service are offered through a third-party registered broker-dealer and investment advisor. FSB Wealth Management receives fees from advisory services and commissions on individual investment and insurance products purchased by clients. The assets held for wealth management customers are not assets of the Company and, accordingly, are not reflected in the Company’s consolidated balance sheets. On August 17, 2021, the Bank entered into a definitive agreement with an investment advisory and wealth management firm (the “seller”) to purchase certain of its client accounts and client relationships for a purchase price of $347,000 (included in other assets at March 31, 2022 and December 31, 2021 net of accumulated amortization), of which $172,000 was paid at closing. Each client account has been assigned a value, and as each client transfers to the Bank, 85% of this value will be paid to the seller. By May 31, 2022, or upon mutual agreement that the transition of client accounts is complete, whichever is earlier, the balance of the purchase price will be paid to the seller. As of March 31, 2022, approximately $23.5 million of purchased client accounts are included in total assets under management. Assets under management totaled approximately $90.9 million and $88.0 million at March 31, 2022 and December 31, 2021, respectively. The client accounts purchased are recorded as a customer list intangible asset. Identifiable intangible assets that are subject to amortization will be reviewed for impairment, at least annually, based on their fair value. Any impairment will be recognized as a charge to earnings and the adjusted carrying amount of the intangible asset will become its new accounting basis. The remaining useful life of the intangible asset will also be evaluated each reporting period to determine whether events and circumstances warrant a revision to the remaining period of amortization. The Company is amortizing the customer list intangible on a straight-line basis over a ten year period. During the three months ended March 31, 2022 and 2021, $9,000 and $-0- of amortization expense was recorded in other expense, respectively.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards As an “emerging growth company,” as defined in Title 1 of Jumpstart Our Business Startups (JOBS) Act, the Company has elected to use the extended transition period to delay adoption of new or reissued accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. As a result, the Company’s consolidated financial statements may not be comparable to the financial statements of public companies that comply with such new or revised accounting standards without an extended transition period. As of March 31, 2022, there was no significant difference in the comparability of the Company’s consolidated financial statements as a result of this extended transition period except for the accounting treatment for measuring and recording the Company’s allowance for loan losses. The Company measures and records an allowance for loan losses based upon the incurred loss model while other public companies may be required to calculate their allowance for loan losses based upon the current expected credit loss (“CECL”) model. As a smaller reporting company the planned implementation of the CECL model is January 1, 2023. The CECL approach requires an estimate of the loan loss expected over the life of the loan, while the incurred loss approach delays the recognition of a loan loss until it is probable a loss event has occurred. The Company’s status as an “emerging growth company” will end on the earlier of: (i) the last day of the fiscal year of the Company during which it had total annual gross revenues of $1.07 billion (as adjusted for inflation) or more; (ii) the last day of the fiscal year of the Company following the fifth anniversary of the effective date of the Company’s initial public offering; (which will be December 31, 2024 for the Company) (iii) the date on which the Company has, during the previous three-year period, issued more than $1.0 billion in non-convertible debt; or (iv) the date on which the Company is deemed to be a “large accelerated filer” under Securities and Exchange Commission regulations (generally, at least $700 million of voting and non-voting equity held by non-affiliates). In January 2020, the FASB issued ASU 2020-1, “Investments – Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) – Clarifying the Interactions Between Topic 321, Topic 323, and Topic 815 (A Consensus of the Emerging Issues Task Force),” In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” In February 2016, the FASB issued ASU 2016-02, “ Leases (Topic 842). Codification Improvements to Topic 842, Leases “Targeted Improvements,”
Recent Accounting Pronouncements	Recent Accounting Pronouncements Yet to Be Adopted The Company considers the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either not applicable or are expected to have an immaterial impact on the Company’s consolidated financial statements. In March 2022, the FASB issued ASU 2022-2, “Financial Instruments-Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures,” which eliminates the troubled debt restructuring (“TDR”) accounting model for creditors that have adopted Topic 326, “Financial Instruments – Credit Losses.” “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” In January 2021, the FASB issued ASU 2021-1, “Reference Rate Reform (Topic 848) (Scope),” In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848),” In February 2020, the FASB issued ASU 2020-2, “Financial Instruments – Credit Losses (Topic 326) and Leases (Topic 842) - Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section on Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842).” In November 2019, the FASB issued ASU 2019-11, “Codification Improvements to Topic 326, Financial Instruments – Credit Losses,” “Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates,” “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” “Leases (Topic 842),” In April 2019, the FASB issued ASU 2019-04, “Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments,” “Financial Instruments—Credit Losses, Topic 326.” In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which creates a new credit impairment standard for financial assets measured at amortized cost and available-for-sale debt securities. The ASU requires financial assets measured at amortized cost (including loans and held-to-maturity debt securities) to be presented at the net amount expected to be collected, through an allowance for credit losses that are expected to occur over the remaining life of the asset, rather than incurred losses. The ASU requires that credit losses on available-for-sale debt securities be presented as an allowance rather than as a direct write-down. The measurement of credit losses for newly recognized financial assets (other than certain purchased assets) and subsequent changes in the allowance for credit losses are recorded in the statement of income as the amounts expected to be collected change. The ASU was originally to be effective for fiscal years beginning after December 15, 2020 and interim periods within fiscal years beginning after December 15, 202 1 . In November 2018, the FASB issued ASU 2018-19, “Codification Improvements to Topic 326, Financial Instruments-Credit Losses,” extending the implementation date by one year for smaller reporting companies and clarifying that operating lease receivables are outside the scope of Accounting. On October 16, 2019, the FASB approved a proposal to delay the implementation of this standard for smaller reporting companies to years beginning after December 15, 2022. Early adoption is permitted. Upon adoption, however, the Company will apply the standard’s provisions as a cumulative effect adjustment to equity capital as of the first reporting period in which the guidance is effective. Upon adoption, the Company expects a change in the processes and procedures to calculate the allowance for loan losses, including changes in the assumptions and estimates to consider expected credit losses over the life of the loan versus the current accounting practice that utilizes the incurred loss model. The Company is reviewing the requirements of ASU 2016-13 and is developing and implementing processes and procedures to ensure it is fully compliant with the amendments at the adoption date. At this time, the Company anticipates the allowance for loan losses will increase as a result of the implementation of this ASU; however, until its evaluation is complete, the magnitude of the increase will be unknown .
