Nature of Business and Significant Accounting Policies
Nature of Business and Significant Accounting Policies	1. Nature of Business and Significant Accounting Policies The financial statements include accounts of Rhinebeck Bancorp, Inc. (the “Company”), a stock holding company, and its wholly-owned subsidiary, Rhinebeck Bank (the “Bank”), a New York chartered stock savings bank. The primary purpose of the Company is to act as a holding company for the Bank. The Bank provides a full range of banking and financial services to consumer and commercial customers through its fourteen branches and two representative offices located in Dutchess, Ulster, Orange, and Albany counties. Financial services, including investment advisory and financial product sales, are offered through a division of the Bank doing business as Rhinebeck Asset Management (“RAM”). The unaudited consolidated financial statements reflect all adjustments, which in the opinion of management, are necessary for a fair presentation of the results of the interim periods and are of a normal and recurring nature. Operating results for the three or six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021 or for any other period. The unaudited financial statements and other financial information contained in this Quarterly Report on Form 10-Q should be read in conjunction with the audited financial statements, and related notes, of Rhinebeck Bancorp, Inc. and Rhinebeck Bank at and for the year ended December 31, 2020 contained in the Company’s Annual Report on Form 10-K For more information regarding the Company’s significant accounting policies, see the Notes to the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K Annual Report on Form 10-K Basis of Financial Statements Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and general practices within the banking industry. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities, as of the date of the consolidated statements of financial condition and reported amounts of revenues and expenses for the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of securities and other real estate owned, the evaluation of investment securities for other-than-temporary impairment, the evaluation of goodwill for impairment, the valuation of deferred tax assets and the determination of pension obligations. Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany accounts and transactions have been eliminated in consolidation. On March 12, 2021, the Bank completed a branch purchase and assumption transaction with ConnectOne Bank. Management concluded that the acquisition represented a business combination, which is accounted for using the acquisition method, with the results of operations included in the Company’s consolidated financial statements as of the acquisition date. For additional information, see Note 2. Reclassifications Certain amounts in the prior year consolidated financial statements have been reclassified to conform to the current year’s presentation. COVID-19 Significant progress has been made to combat the outbreak of COVID-19; however, the global pandemic has adversely impacted a broad range of industries in which the Company's customers operate and could still impair their ability to fulfill their financial obligations to the Company. The Company’s business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. If there is a resurgence in the virus or variant strains of the virus increase, the Company could experience further adverse effects on its business, financial condition, results of operations and cash flows. It is not possible to know the full extent of the impact of COVID-19 and the effects it will have on the Company's future operations. Impact of Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13 on “Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. This ASU requires credit losses on most financial assets be measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss (“CECL”) model). Under this model, entities will estimate credit losses over the entire contractual term of the instrument (considering estimated prepayments, but not expected extensions or modifications unless reasonable expectation of a troubled debt restructuring exists) from the date of initial recognition of that instrument. The measurement of expected credit losses is based upon relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the reported amount. On October 16, 2019, the FASB approved a delay for conversion to the CECL methodology to January 2023 for smaller reporting companies, other public business entities, private companies and non-profits. The Company is currently assessing the effect of ASU No. 2016-13 and has engaged with a software vendor to assist in its efforts. Emerging Growth Company Status As an emerging growth company, the Company may delay adoption of new or revised financial accounting standards until such date that the standards are required to be adopted by non-issuer companies. If such standards would not apply to non-issuer companies, no deferral would be applicable. The Company is taking advantage of the benefits of the extended transition periods allowed under the Jumpstart Our Business Startups Act. Accordingly, the Company’s consolidated financial statements may not be comparable to those of public companies that adopt new or revised financial accounting standards as of an earlier date. The effective dates of the recent accounting standards reflect those that relate to non-issuer companies. ​

Acquisition	2. Acquisition On October 26, 2020, the Bank entered into a branch purchase and assumption agreement with ConnectOne Bank, the wholly-owned subsidiary of ConnectOne Bancorp, Inc., to acquire two branches located in Orange County, New York, as well as certain deposits and other assets and liabilities. The transaction closed on March 12, 2021 with the transfer of $33,863 of deposits. Management concluded that the acquisition represented a business combination, which is accounted for using the acquisition method, with the results of operations included in the Company’s consolidated financial statements as of the acquisition date. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed in the March 12, 2021 transaction with ConnectOne, and reflects all adjustments made to the fair value of the opening balance sheet through June 30, 2021: ​ ​ ​ ​ ​ ​ ​ March 12, Fair value of consideration transferred, assets acquired and liabilities assumed ​ 2021 Total cash received on acquisition ​ $ 32,767 ​ ​ ​ ​ Assets acquired ​ ​ ​ Fixed assets ​ ​ 113 Reimbursed expenses ​ ​ 9 Core deposit intangible (1) ​ ​ 330 Total assets acquired ​ ​ 452 ​ ​ ​ ​ Liabilities assumed ​ ​ ​ Deposits ​ ​ 33,863 Mark-to-market adjustment ​ ​ 181 Total liabilities assumed ​ ​ 34,044 Net liabilities acquired ​ ​ (33,592) Goodwill recognized ​ $ 825 _____________________________ (1) The core deposit intangible was determined to have an estimated life of approximately 13 years .

The Company does not intend to sell the securities and it is not likely that the Company will be required to sell the securities before recovery of their amortized cost basis, which may be maturity; therefore, the Company did not consider those investments to be other-than-temporarily impaired at June 30, 2021. The amortized cost and fair value of available for sale debt securities at June 30, 2021 and December 31, 2020, by contractual maturities, are presented below. Actual maturities of mortgage-backed securities may differ from contractual maturities because the mortgages underlying the securities may be called or repaid without any penalties. Because mortgage-backed securities are not due at a single maturity date, they are not included in the maturity categories in the following maturity summary: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2021 ​ December 31, 2020 ​ Amortized Cost Fair Value Amortized Cost Fair Value Maturity: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Within 1 year ​ $ 17,778 ​ $ 17,784 ​ $ 102 ​ $ 102 After 1 but within 5 years ​ 34,133 ​ 33,998 ​ 2,155 ​ 2,155 After 5 but within 10 years ​ 18,314 ​ 18,406 ​ 9,946 ​ 10,162 After 10 years ​ 656 ​ 670 ​ 655 ​ 664 Total Maturities ​ 70,881 ​ 70,858 ​ 12,858 ​ 13,083 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Mortgage-backed securities ​ 130,565 ​ 130,439 ​ 88,197 ​ 89,270 Other ​ 652 ​ 641 ​ 621 ​ 580 Total ​ $ 202,098 ​ $ 201,938 ​ $ 101,676 ​ $ 102,933 ​ At June 30, 2021 and December 31, 2020, available for sale securities with a carrying value of $13,625 and $18,123, respectively, were pledged to secure Federal Home Loan Bank of New York (“FHLB”) borrowings. In addition, at June 30, 2021 and December 31, 2020, $1,060 and $1,059 of available for sale securities were pledged to secure borrowings at the Federal Reserve Bank of New York (“FRB”), respectively.

Impaired loans include nonperforming loans and loans modified as troubled debt restructurings (“TDRs”). Loan modifications, which resulted in these loans being considered TDRs, are primarily in the form of rate concessions and extensions of maturity dates that are made specifically due to hardships experienced by the customer. The Company does not generally recognize interest income on a loan in an impaired status. At June 30, 2021 and December 31, 2020, three loans totaling $1,506 and $1,571, included in impaired loans, were identified as TDRs. There were no new TDRs in 2020 or the first six months of 2021. At June 30, 2021 and December 31, 2020, all TDR loans were performing in accordance with their restructured terms. At June 30, 2021 and December 31, 2020, the Company had no commitments to advance additional funds to borrowers under TDR loans. Residential mortgage and consumer loans secured by residential real estate properties for which formal foreclosure proceedings are in process totaled $648 and $636 at June 30, 2021 and December 31, 2020, respectively. The Company services certain loans that it has sold without recourse to third parties. The aggregate balances of loans serviced for others were $310,480 and $300,700 as of June 30, 2021 and December 31, 2020, respectively. The balance of capitalized servicing rights, included in other assets at June 30, 2021 and December 31, 2020, were $2,660 and $2,390, respectively. Fair value exceeds carrying value. No impairment charges related to servicing rights were recognized during the period ended June 30, 2021 or the year ended December 31, 2020.

At June 30, 2021 and December 31, 2020, the Bank had access to a preapproved secured line of credit with the FHLB of $604,993 and $564,330, respectively. Borrowings under this line require collateralization through the pledge of specific loans and securities. At June 30, 2021 and December 31, 2020, the Bank had pledged assets of $177,169 and $175,011, respectively. ​ The outstanding principal amounts and the related terms and rates at June 30, 2021 were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Term Principal Maturity Rate ​ Due in one year Long term 3 year amortizing ​ $ 3,417 ​ May 16, 2022 2.49 % ​ $ 3,417 ​ — 3 year bullet ​ ​ 10,000 ​ May 16, 2022 ​ 2.44 % ​ ​ 10,000 ​ ​ — 3 year amortizing ​ ​ 8,822 ​ February 28, 2023 ​ 1.32 % ​ ​ 5,016 ​ ​ 3,806 Total ​ $ 22,239 ​ Weighted Average Rate 2.00 % ​ $ 18,433 ​ $ 3,806 ​ The Bank is required to maintain an investment in capital stock of the FHLB, as collateral, in an amount equal to a certain percentage of its outstanding debt. FHLB stock is considered restricted stock and is carried at cost. The Bank evaluates FHLB stock for impairment based on the ultimate recovery ability of the cost. No impairment was recognized at either June 30, 2021 or December 31, 2020. Subordinated Debt In addition to the Bank, the Company has one other wholly-owned subsidiary, RSB Capital Trust I (the “Trust”). In 2005, the Trust issued $5,000 of pooled trust preferred securities in a private placement and issued 155 shares of common stock at $1 par value per share, now owned by the Company. The Trust, which has no independent assets or operations, was formed in 2005 for the sole purpose of issuing trust preferred securities and investing the proceeds thereof in an equivalent amount of junior subordinated debentures. The proceeds from the issuance of the trust preferred securities were down-streamed to the Bank and are currently considered Tier 1 capital for purposes of determining the Bank’s capital ratios. The trust securities bear interest at 3-month LIBOR plus 2.00%. The duration of the Trust is 30 years. The subordinated debt securities of $5,155 are unsecured obligations of the Company and are subordinate and junior in right of payment to all present and future senior indebtedness of the Company. The Company has entered into a guarantee, which together with its obligations under the subordinated debt securities and the declaration of trust governing the Trust, including its obligations to pay costs, expenses, debts and liabilities, provides a full and unconditional guarantee of amounts on the capital securities. The subordinated debentures, which bear interest at 3-month LIBOR plus 2.00% (2.15% at June 30, 2021 and 2.21% at December 31, 2020) mature on May 23, 2035. Other Borrowings The Bank also has an unsecured, uncommitted $10,000 line of credit with Zions Bank. There were no advances outstanding under this line of credit at either June 30, 2021 or December 31, 2020.

Employee Benefits	9. Employee Benefits Pension Plan The Bank maintains a noncontributory defined benefit pension plan covering substantially all of its employees 21 years of age or older who had completed at least one year of service as of September 30, 2012, the effective date on which the Board of Directors of the Bank voted to freeze the defined benefit plan. The following table sets forth the plan’s funded status and amounts recognized in the Company’s consolidated statements of financial condition: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ ​ 2021 2020 ​ Projected and accumulated benefit obligation ​ $ (23,524) ​ $ (23,964) ​ Plan assets at fair value ​ 22,418 ​ 22,634 ​ Funded status included in accrued expenses and other liabilities ​ $ (1,106) ​ $ (1,330) ​ ​ The net periodic pension cost and amounts recognized in other comprehensive income are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Six months ended June 30, ​ ​ 2021 2020 ​ Interest cost ​ $ 295 ​ $ 335 ​ Expected return on plan assets ​ (472) ​ (529) ​ Amortization of unrecognized loss ​ 179 ​ 143 ​ Net periodic cost (benefit) ​ $ 2 ​ $ (51) ​ ​ The expected long-term rate of return on plan assets has been determined by applying historical average investment returns from published indexes relating to the current allocation of assets in the plan. Plan assets are invested in pooled separate accounts consisting of underlying investments in ten diversified investment funds. As of June 30, 2021, the investment funds included seven equity funds and three fixed income bond funds, each with its own investment objectives, investment strategies and risks, as detailed in the Company’s investment policy statement. The Company determines the appropriate strategic asset allocation versus plan liabilities, as governed by the investment policy statement. The assets of the plan are invested under the supervision of the Company’s investment committee in accordance with the investment policy statement. The investment options of the plan are chosen in a manner consistent with generally accepted standards of fiduciary responsibility. The investment performance of the Company’s individual investment managers, with the assistance of the Company’s investment consultant, is monitored on a quarterly basis and is reviewed at least annually relative to the objectives and guidelines as stated in the Company’s investment policy statement. The Company did not make a contribution to the plan in the first six months of 2021 or 2020. The fair value of the Company’s pension plan assets, by fair value hierarchy, are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2021 ​ Level 1 Level 2 Level 3 Total Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Investment in separate accounts ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fixed income ​ $ 15,716 ​ $ — ​ $ — ​ $ 15,716 Equity ​ 6,702 ​ — ​ — ​ 6,702 Total assets at fair value ​ $ 22,418 ​ $ — ​ $ — ​ $ 22,418 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ Level 1 Level 2 Level 3 Total Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Investment in separate accounts ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fixed income ​ $ 15,189 ​ $ — ​ $ — ​ $ 15,189 Equity ​ 6,206 ​ — ​ — ​ 6,206 Other ​ ​ 1,239 ​ ​ — ​ ​ — ​ ​ 1,239 Total assets at fair value ​ $ 22,634 ​ $ — ​ $ — ​ $ 22,634 ​ The pooled separate accounts are valued at the net asset per unit based on either the observable net asset value of the underlying investment or the net asset value of the underlying pool of securities. Net asset value is based on the value of the underlying assets owned by the fund, minus its liabilities and then divided by the number of shares outstanding. For a detailed disclosure on the Bank’s pension and employee benefits plans, please refer to Note 8 of the Company’s Consolidated Financial Statements for the year ended December 31, 2020 included in the Company’s Annual Report on Form 10-K Defined Contribution Plan The Company sponsors a 401(k) defined contribution plan. Participants are permitted, in accordance with the provisions of Section 401(k) of the Internal Revenue Code, to contribute up to 25% of their earnings (as defined) into the plan with the Company matching up to 6%, subject to Internal Revenue Service limitations. The Company’s contributions charged to operations amounted to $527 and $490 for the six months ended June 30, 2021 and 2020, respectively. ​ ​ Deferred Compensation Arrangements Directors’ Plan The Bank’s Deferred Compensation Plan for Fees of Directors, as amended and restated effective January 1, 2005 (the “Directors’ Plan”), covers Directors who elect to defer receipt of all or a portion of their fees until separation from service. Upon resignation, retirement, or death, the participant’s total deferred compensation, including earnings thereon, will be paid out. At June 30, 2021 and December 31, 2020, total amounts due of $2,743 and $2,483, respectively, are included in accrued expenses and other liabilities. Total expenses related to the Directors’ Plan were $71 and $85 for the six months ended June 30, 2021 and 2020, respectively, which were included in other non-interest expense in the consolidated statements of income. Executive Long-Term Incentive and Retention Plan The Bank maintains an Executive Long-Term Incentive and Retention Plan (the “Executive Plan”). Participation in the Executive Plan is limited to officers of the Company designated as participants by the Board of Directors and who filed a properly completed and executed participation agreement in accordance with the terms of the Executive Plan. Under the Executive Plan, the Board of Directors may grant annual incentive awards equal to a percentage of a participant’s base salary at the rate in effect on the last day of the Plan year, as determined by the Board of Directors based on the attainment of criteria established annually by the Board of Directors. Incentive awards under the Executive Plan are credited to the participant’s incentive benefit account as of the last day of the Executive Plan year to which the award relates and earn interest at a rate determined annually by the Board of Directors. Participants vest in their benefit accounts in accordance with the vesting schedule approved by the Board of Directors, which ranges from one Group Term Replacement Plan Under the terms of the “Group Term Replacement Plan”, the Company provides postretirement life insurance benefits to certain officers. The liability related to these postretirement benefits is being accrued over the individual participants’ service period and aggregated $1,408 and $1,387, at June 30, 2021 and December 31, 2020, respectively. The Company recognized expenses of $21 and $29 for the six-month periods ended June 30, 2021 and June 30, 2020, respectively, related to this plan, which are included in salaries and employee benefits expense in the consolidated statements of income. Other Director and Officer Postretirement Benefits The Company has individual fee continuation agreements with certain directors and a supplemental retirement agreement with an executive officer which provide for fixed postretirement benefits to be paid to the directors and the officer, or their beneficiaries, for periods ranging from 15 to 20 years. In addition, the Company has agreements with certain directors which provide for certain postretirement life insurance benefits. The liability related to these postretirement benefits is being accrued over the individual participants’ service period and aggregated $1,969 and $2,148 at June 30, 2021 and December 31, 2020, respectively. The Company recognized expenses of $37 and $43 for the six months ended June 30, 2021 and 2020, respectively, related to these benefits, which are included in other non-interest expenses in the consolidated statements of income. Employee Stock Ownership Plan On January 1, 2019, the Bank established an Employee Stock Ownership Plan (“ESOP”) to provide eligible employees the opportunity to own Company stock. The plan is a tax-qualified retirement plan for the benefit of Bank employees. On January 16, 2019, the Company granted a loan to the ESOP for the purchase of 436,425 shares of the Company’s common stock at a price of $10.00 per share. The loan obtained by the ESOP from the Company is payable annually over 20 years at a rate per annum equal to the Prime Rate, reset annually on January 1st (3.25% at January 1, 2021). Loan payments are funded by cash contributions from the Bank. The loan is secured by the shares purchased, which are held in a suspense account for allocation among participants as the loan is repaid. The balance of the ESOP loan at June 30, 2021 was $4,087. Contributions are allocated to eligible participants on the basis of compensation, subject to federal tax limits. The number of shares committed to be released annually is 21,821 through 2039. Shares held by the ESOP include the following: ​ ​ ​ ​ ​ ​ ​ ​ Six months ended ​ Year ended ​ ​ June 30, ​ December 31, ​ ​ 2021 2020 Allocated ​ 43,642 21,821 Committed to be allocated ​ 10,908 21,821 Unallocated ​ 381,875 392,783 Paid out to participants ​ (68) ​ (68) Total shares ​ 436,357 436,357 ​ The fair value of unallocated shares was $4,182 at June 30, 2021. Total compensation expense recognized in connection with the ESOP for the six months ended June 30, 2021 and 2020 was $109 and $92, respectively. Share-Based Compensation Plan On May 26, 2020, stockholders of the Company approved the 2020 Equity Incentive Plan (the “EIP”). The EIP authorizes the issuance or delivery to participants of up to 763,743 shares of Rhinebeck Bancorp common stock pursuant to grants of incentive and non-qualified stock options, restricted stock awards and restricted stock units. Of this number, the maximum number of shares of Rhinebeck Bancorp common stock that may be issued under the EIP pursuant to the exercise of stock options is 545,531 shares, and the maximum number of shares of Rhinebeck Bancorp common stock that may be issued as restricted stock awards or restricted stock units is 218,212 shares. These amounts represent 4.90% and 1.96%, respectively, of the number of shares of common stock issued in the stock offering of Rhinebeck Bancorp, including the shares issued to Rhinebeck Bancorp, MHC. Pursuant to terms of the EIP, on August 25, 2020, the Board of Directors granted restricted stock and stock options to employees and directors. All of the awards vest annually over a three-year period from the date of the grant and the term of each option is ten years. As of June 30, 2021, there were 97,146 stock options and 48,443 restricted stock awards that remain available for future grants. The fair value of each option granted under the EIP is estimated on the date of grant using the Black-Scholes Option-Pricing Model. The expected volatility is based on the historical volatility of a peer group of comparable SEC-reporting bank holding companies. The dividend yield assumption is based on the Company’s expectation of dividend payouts. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the date of grant. The Company has elected to recognize forfeitures as they occur. ​ ​ A summary of options under the 2020 EIP as of June 30, 2021 is presented below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted - ​ Weighted-Average ​ ​ Number of ​ Average ​ Remaining Contractual ​ ​ Shares ​ Exercise Price ​ Term (in Years) Options outstanding at beginning of year ​ 448,385 ​ $ 6.61 ​ 9.66 Options granted ​ - ​ ​ - ​ - Options exercised ​ - ​ ​ - ​ - Forfeited ​ - ​ ​ - ​ - Options outstanding at June 30, 2021 ​ 448,385 ​ $ 6.61 ​ 9.17 Options exercisable at June 30, 2021 ​ - ​ ​ - ​ - ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ At June 30, 2021, the aggregate intrinsic value of the shares outstanding, which fluctuates based on changes in the fair market value of the Company’s stock, was $1,944 . The aggregate intrinsic value represents the total pre-tax intrinsic value (i.e., the difference between the Company’s closing stock price on the last trading day of period and the weighted-average exercise price, multiplied by the number of shares) that would have been received by the option holders had all option holders exercised their options on June 30, 2021. ​ As of June 30, 2021, there was $538 of unrecognized compensation cost related to the nonvested stock options granted under the 2020 EIP. The cost is expected to be recognized over a remaining period of 2.17 years. The following table summarizes the Company’s restricted stock activity for the six months ended June 30, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted-Average ​ ​ Number ​ ​ Grant Date ​ ​ of Shares ​ ​ Fair Value per Share Non-vested restricted stock at beginning of year ​ 169,769 ​ $ 6.57 Granted ​ - ​ - Vested ​ - ​ - Forfeited ​ - ​ - Non-vested restricted stock at June 30, 2021 ​ 169,769 ​ $ 6.57 ​ As of June 30, 2021, there was $800 of unrecognized compensation cost related to the nonvested restricted stock awards granted under the 2020 EIP. The cost is expected to be recognized over a remaining period of 2.15 years. For the six months ended June 30, 2021, share-based compensation under the plan was $308.

Leases
Leases	10. Leases As of June 30, 2021, the Company leases real estate for eight branch offices and two administrative offices under various lease agreements. All of our leases are classified as operating leases, and therefore, were previously not recognized on the Company’s consolidated statements of financial condition. With the adoption of Accounting Standards Update 2016-02, Leases (Topic 842), operating lease agreements are required to be recognized on the consolidated statements of financial condition as a right-of-use (“ROU”) asset and a corresponding lease liability. The calculated amount of the ROU assets and lease liabilities are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. The Company’s leases have maturities which range from 2021 to 2041, some of which include lessee options to extend the lease term. If 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 weighted average remaining life of the lease terms for these leases was 12.6 years as of June 30, 2021. As most of our leases do not provide an implicit rate, the Company used its incremental borrowing rate, the rate of interest to borrow on a collateralized basis for a similar term, at the lease commencement date. The Company utilized a weighted average discount rate of 2.51% in determining the lease liability as of June 30, 2021. For the six months ended June 30, 2021, total operating lease costs were $344 and were included in occupancy and other expense. Deferred rent liability was $159 at June 30, 2021 and $176 at December 31, 2020. The right-of-use asset, included in other assets, accrued expenses and other liabilities, ​ Future minimum payments for operating leases with initial or remaining terms of one year or more as of June 30, 2021 were as follows: ​ ​ ​ ​ ​ Years ending December 31: ​ ​ 2021 ​ $ 396 2022 ​ 754 2023 ​ 732 2024 ​ 729 2025 ​ 743 Thereafter ​ 5,822 Total future minimum lease payments ​ ​ 9,176 Amounts representing interest ​ ​ (1,441) Present Value of Net Future Minimum Lease Payments ​ $ 7,735 ​

Commitments and Contingencies and Derivatives
Commitments and Contingencies and Derivatives	11. Commitments and Contingencies and Derivatives Legal Matters The Company is involved in various legal proceedings which have arisen in the normal course of business. Management believes that resolution of these matters will not have a material effect on the Company’s financial condition or results of operations. Employment Agreements The Company has entered into employment agreements with certain officers. The agreements provide for base salaries and incentive compensation based on performance criteria outlined in the agreements. The agreements also provide for insurance and various other benefits. Financial Instruments with Off-Balance-Sheet Risk In the normal course of business, the Company is a party to financial instruments with off-balance-sheet risk to meet the financing needs of its customers. These financial instruments include standby letters of credit and commitments to extend credit, which include new loan commitments and undisbursed portions of construction loans and other lines of credit. These financial instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the statements of financial condition. The contractual amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments. The contractual amounts of commitments to extend credit represent the amounts of potential loss should the contract be fully drawn upon, the customer defaults and the value of any existing collateral become worthless. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. Financial instruments whose contract amounts represent off-balance sheet credit risk are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ ​ 2021 2020 ​ Commitments to extend credit summarized as follows: ​ ​ ​ ​ ​ ​ ​ Future loan commitments ​ $ 11,418 ​ $ 14,356 ​ Undisbursed construction loans ​ 4,424 ​ 3,493 ​ Undisbursed home equity lines of credit ​ 10,284 ​ 10,686 ​ Undisbursed commercial and other line of credit ​ 51,190 ​ 63,911 ​ Standby letters of credit ​ 3,050 ​ 5,681 ​ Total ​ $ 80,366 ​ $ 98,127 ​ ​ Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Since these commitments could expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the counterparty. Collateral held varies but may include residential and commercial property, deposits and securities. Interest Rate Swaps The Company enters into interest rate swaps that allow commercial loan customers to effectively convert a variable-rate loan agreement to a fixed-rate loan agreement. Under these agreements, the Company simultaneously enters into a variable-rate loan and interest rate swap agreements with a customer. The Company then enters into a corresponding and offsetting swap agreement with a third party to hedge its exposure created by the customer agreements. The interest rate swaps with both the customers and third parties are not designated as hedges under FASB ASC Topic 815, Derivatives and Hedging, and are marked to market through earnings. The fair values of the swaps are recorded as both an asset and a liability, in other assets and other liabilities, respectively, in equal amounts for these transactions. The accrued interest receivable and payable of $4 and $0 related to our swaps is recorded in other assets and other liabilities as of June 30, 2021 and 2020, respectively. Summary information regarding these derivatives is presented below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ ​ 2021 ​ 2020 ​ Notational amount ​ $ 3,950 ​ ​ $ 1,875 ​ Fair value ​ $ 75 ​ ​ $ 41 ​ Weighted average pay rates ​ ​ 3.38 % ​ ​ 3.10 % Weighted average receive rates ​ ​ 2.21 % ​ ​ 2.22 % Weighted average maturity (in years) ​ ​ 9.56 ​ ​ ​ 9.92 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Number of Contracts ​ ​ 3 ​ ​ ​ 1 ​ ​

Regulatory Matters
Regulatory Matters	12. Regulatory Matters The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities and certain off-balance-sheet items, as calculated under regulatory accounting practices. The Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. The final rules implementing the BASEL Committee on Banking Supervisor’s Capital Guidance for U.S. Banks (BASEL III) became effective for the Bank on January 1, 2016. Compliance with the requirements was phased in over a four year period with full compliance as of January 1, 2019. All presented capital ratios are calculated using BASEL III rules. Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the tables below) of total, common equity Tier 1 and Tier I capital (as defined in the regulations) to risk-weighted assets (as defined) and of Tier I capital (as defined) to average assets (as defined). Management believes, as of June 30, 2021 and December 31, 2020, that the Bank met all capital adequacy requirements to which they are subject. The most recent notification from the Federal Deposit Insurance Corporation (“FDIC”) categorized the Bank as “well capitalized” under the regulatory framework.

Fair Value
Fair Value	13. Fair Value The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. A description of the valuation methodologies used for assets and liabilities recorded at fair value and for estimating fair value for financial and non-financial instruments not recorded at fair value, is set forth below. Cash and Due from Banks The carrying amount is a reasonable estimate of fair value. Available for Sale Securities Where quoted prices are available in an active market for identical securities, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities include marketable equity securities and U.S. Treasury obligations. If quoted prices are not available, then fair values are estimated by using pricing models (i.e., matrix pricing) or quoted prices of securities with similar characteristics and are classified within Level 2 of the valuation hierarchy. Examples of such instruments include government agency bonds, mortgage-backed securities and municipal bonds. Level 3 securities include securities for which significant unobservable inputs are utilized. Available for sale securities are recorded at fair value on a recurring basis. FHLB Stock The carrying value of FHLB stock approximates fair value based on the redemption provisions of the FHLB. Loans Loans receivable are carried at cost. For variable rate loans which reprice frequently carrying values are a reasonable estimate of fair values, adjusted for credit losses inherent in the portfolios. The fair value of fixed rate loans is estimated by discounting the future cash flows using the year end rates, estimated using local market data, at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities, adjusted for credit losses inherent in the portfolios. The Company does not record loans at fair value on a recurring basis. However, from time to time, nonrecurring fair value adjustments to collateral-dependent impaired loans are recorded to reflect partial write-downs based on the observable market price or current appraised value of collateral. Other Real Estate Owned Other real estate owned represents real estate acquired through foreclosure and is carried at fair value less estimated selling costs. Fair value is based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral. These assets are included as Level 3 fair values, based upon the lowest level of input that is utilized in the fair value measurements. Mortgage Servicing Rights The fair value of mortgage servicing rights is based on a valuation model that calculates the present value of estimated future net servicing income. Mortgage servicing rights are carried at the lower of amortized cost or estimated fair value and are included in other assets on the consolidated statements of financial condition. Deposits Deposit liabilities are carried at cost. The fair value of NOW, savings and money market deposits is the amount payable on demand at the reporting date. The fair value of time certificates of deposit is estimated using a discounted cash flow calculation that applies interest rates currently being offered for deposits of similar remaining maturities estimated using local market data to a schedule of aggregated expected maturities on such deposits. Mortgagors’ escrow account The fair value is estimated using a discounted cash flow calculation that applies interest rates currently being offered on deposited escrow accounts of similarly expected maturities. Advances from the FHLB The fair value of the advances is estimated using a discounted cash flow calculation that applies current FHLB interest rates for advances of similar maturity to a schedule of maturities of such advances. Subordinated Debt Based on the floating rate characteristic of these instruments, the carrying value is considered to approximate fair value. Off-Balance-Sheet Instruments Fair values for off-balance-sheet lending commitments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standings. Such amounts are not significant. Loan level interest rate Swaps The fair value is based on settlement values adjusted for credit risks associated with the counterparties and the Company and observable market interest rate curves. ​ ​ ​ The following tables detail the assets that are carried at fair value on a recurring basis as of the periods shown and indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine the fair value: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Quoted Prices in ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Active Markets ​ Significant ​ Significant ​ ​ ​ ​ ​ for Identical ​ Observable ​ Unobservable ​ Balance Assets (Level 1) Inputs (Level 2) Inputs (Level 3) ​ ​ June 30, 2021 Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury securities ​ $ 45,267 ​ $ 45,267 ​ $ — ​ $ — U.S. government agency mortgage-backed securities-residential ​ ​ 130,439 ​ ​ — ​ ​ 130,439 ​ ​ — U.S. government agency securities ​ 11,858 ​ — ​ 11,858 ​ — Municipal securities ​ 7,046 ​ — ​ 6,886 ​ 160 Corporate Bonds ​ ​ 6,687 ​ ​ — ​ ​ 6,687 ​ ​ — Other ​ 641 ​ — ​ 641 ​ — Total available for sale securities ​ ​ 201,938 ​ ​ 45,267 ​ ​ 156,511 ​ ​ 160 Loan level interest rate swaps ​ ​ 75 ​ ​ — ​ ​ 75 ​ ​ — Total assets ​ $ 202,013 ​ $ 45,267 ​ $ 156,586 ​ $ 160 Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loan level interest rate swaps ​ ​ 75 ​ ​ — ​ ​ 75 ​ ​ — Total liabilities ​ $ 75 ​ $ — ​ $ 75 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. government agency mortgage-backed securities – residential ​ $ 89,270 ​ $ — ​ $ 89,270 ​ $ — U.S. government agency securities ​ 7,161 ​ — ​ 7,161 ​ — Municipal securities ​ 1,476 ​ — ​ 1,316 ​ 160 Corporate Bonds ​ ​ 4,446 ​ ​ — ​ ​ 4,446 ​ ​ — Other ​ ​ 580 ​ ​ — ​ 580 ​ — Total available for sale securities ​ ​ 102,933 ​ ​ — ​ ​ 102,773 ​ ​ 160 Loan level interest rate swaps ​ ​ 41 ​ ​ — ​ ​ 41 ​ ​ — Total assets ​ $ 102,974 ​ $ — ​ $ 102,814 ​ $ 160 Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loan level interest rate swaps ​ ​ 41 ​ ​ — ​ ​ 41 ​ ​ — Total liabilities ​ $ 41 ​ $ — ​ $ 41 ​ $ — ​ The following tables detail the assets carried at fair value and measured at fair value on a nonrecurring basis as of June 30, 2021 and December 31, 2020 and indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine the fair value: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Quoted Prices in ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Active Markets ​ Significant ​ Significant ​ ​ ​ ​ ​ for Identical ​ Observable ​ Unobservable ​ Balance Assets (Level 1) Inputs (Level 2) Inputs (Level 3) ​ ​ June 30, 2021 Impaired loans, with specific reserves ​ $ 172 ​ $ — ​ $ — ​ $ 172 Other real estate owned ​ 89 ​ — ​ — ​ 89 Total ​ $ 261 ​ $ — ​ $ — ​ $ 261 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 Impaired loans, with specific reserves ​ $ 509 ​ $ — ​ $ — ​ $ 509 Other real estate owned ​ 139 ​ — ​ — ​ 139 Total ​ $ 648 ​ $ — ​ $ — ​ $ 648 ​ The following table presents additional quantitative information about assets measured at fair value on a nonrecurring basis and for which the Company has utilized Level 3 inputs to determine fair value: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Quantitative Information About Level 3 Fair Value Measurements ​ ​ Fair Value ​ Valuation ​ Unobservable ​ Range ​ Estimate Techniques Input (Weighted Average) ​ ​ June 30, 2021 Impaired loans ​ $ 172 Appraisal of collateral (1) Liquidation expenses (3) 0% to 6% ​ ​ ​ ​ ​ ​ ​ Appraisal adjustments (2) 0% to 20% Other real estate owned ​ 89 Appraisal of collateral (1) Liquidation expenses (3) 0% to 6% ​ ​ ​ ​ ​ Appraisal adjustments (2) 0% to 20% ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 Impaired loans ​ $ 509 Appraisal of collateral (1) Liquidation expenses (3) 0% to 6% ​ ​ ​ ​ ​ ​ ​ Appraisal adjustments (2) 0% to 20% Other real estate owned ​ 139 Appraisal of collateral (1) Liquidation expenses (3) 0% to 6% ​ ​ Appraisal adjustments (2) 0% to 20% (1) Fair value is generally through independent appraisals of the underlying collateral that generally include various level 3 inputs which are not identifiable.

The Company discloses fair value information about financial instruments, whether or not recognized in the statements of financial condition, for which it is practicable to estimate that value. Certain financial instruments are excluded from disclosure requirements. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company. The estimated fair value amounts for 2021 and 2020 have been measured as of their respective reporting dates and have not been reevaluated or updated for purposes of these financial statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than amounts reported at each year-end. The information presented should not be interpreted as an estimate of the fair value of the entire Company since a fair value calculation is only required for a limited portion of the Company’s assets and liabilities. Due to the wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Company’s disclosures and those of other companies may not be meaningful.

Earnings Per Share	15. Earnings Per Share Basic earnings per share represent income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed in a manner similar to that of basic earnings per share except that the weighted-average number of common shares outstanding is increased to include the number of incremental shares (computed using the treasury method) that would have been outstanding if all potentially dilutive common stock equivalents (such as options) were issued during the period. Unearned ESOP shares are not deemed outstanding for earnings per share calculations.

Nature of Business and Significant Accounting Policies
Basis of Financial Statement Presentation	Basis of Financial Statements Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and general practices within the banking industry. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities, as of the date of the consolidated statements of financial condition and reported amounts of revenues and expenses for the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of securities and other real estate owned, the evaluation of investment securities for other-than-temporary impairment, the evaluation of goodwill for impairment, the valuation of deferred tax assets and the determination of pension obligations.
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany accounts and transactions have been eliminated in consolidation. On March 12, 2021, the Bank completed a branch purchase and assumption transaction with ConnectOne Bank. Management concluded that the acquisition represented a business combination, which is accounted for using the acquisition method, with the results of operations included in the Company’s consolidated financial statements as of the acquisition date. For additional information, see Note 2.
Reclassifications	Reclassifications Certain amounts in the prior year consolidated financial statements have been reclassified to conform to the current year’s presentation.
COVID-19	COVID-19 Significant progress has been made to combat the outbreak of COVID-19; however, the global pandemic has adversely impacted a broad range of industries in which the Company's customers operate and could still impair their ability to fulfill their financial obligations to the Company. The Company’s business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. If there is a resurgence in the virus or variant strains of the virus increase, the Company could experience further adverse effects on its business, financial condition, results of operations and cash flows. It is not possible to know the full extent of the impact of COVID-19 and the effects it will have on the Company's future operations.
Impact of Recent Accounting Pronouncements	Impact of Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13 on “Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. This ASU requires credit losses on most financial assets be measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss (“CECL”) model). Under this model, entities will estimate credit losses over the entire contractual term of the instrument (considering estimated prepayments, but not expected extensions or modifications unless reasonable expectation of a troubled debt restructuring exists) from the date of initial recognition of that instrument. The measurement of expected credit losses is based upon relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the reported amount. On October 16, 2019, the FASB approved a delay for conversion to the CECL methodology to January 2023 for smaller reporting companies, other public business entities, private companies and non-profits. The Company is currently assessing the effect of ASU No. 2016-13 and has engaged with a software vendor to assist in its efforts.
Emerging Growth Company Status	Emerging Growth Company Status As an emerging growth company, the Company may delay adoption of new or revised financial accounting standards until such date that the standards are required to be adopted by non-issuer companies. If such standards would not apply to non-issuer companies, no deferral would be applicable. The Company is taking advantage of the benefits of the extended transition periods allowed under the Jumpstart Our Business Startups Act. Accordingly, the Company’s consolidated financial statements may not be comparable to those of public companies that adopt new or revised financial accounting standards as of an earlier date. The effective dates of the recent accounting standards reflect those that relate to non-issuer companies.
