Significant Accounting Policies	Note 1. Significant CBM Bancorp, Inc. (“CBM Bancorp” or “Company”) is the holding company for Chesapeake Bank of Maryland (“Bank”) and was formed in connection with the conversion of the Bank from the mutual to the stock form of organization. On September 27, 2018, the mutual to stock conversion of the Bank was completed and the Company became the parent holding company for the Bank. Shares of the Company began trading on the Nasdaq Capital Market on September 28, 2018. The Company is subject to regulation by the Board of Governors of the Federal Reserve System. CBM Bancorp’s primary business is the ownership and operation of the Bank, a community-oriented federal stock savings bank regulated by the Office of the Comptroller of the Currency. The Bank’s primary business activity is the acceptance of deposits from the general public and using the proceeds for loan originations and investments. The Bank is subject to competition from other financial institutions. The Bank is subject to the regulations of certain federal agencies and undergoes periodic examinations by the regulatory authorities. In accordance with federal and state regulations, at the time of the conversion from mutual to stock form, the Bank substantially restricted retained earnings by establishing a liquidation account. The liquidation account will be maintained for the benefit of eligible account holders who continue to maintain their accounts at the Bank after the conversion. The liquidation account will be reduced annually to the extent that eligible account holders have reduced their qualifying deposits. Subsequent increases will not restore an eligible account holder’s interest in the liquidation account. In the event of a complete liquidation of the Bank, each account holder will be entitled to receive a distribution in an amount proportionate to the adjusted qualifying account balances then held. The Company may not pay a dividend on, or repurchase any of, its capital stock, if the effect thereof would cause retained earnings to be reduced below the liquidation account amount or regulatory capital requirements. In addition, the Company is subject to certain other regulations restricting the payment of dividends on, and the repurchase of, its capital stock. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q S-X 10-K Principles of Consolidation The consolidated financial statements include the accounts of CBM Bancorp, Inc. and the Bank, its wholly owned subsidiary. Material intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for losses on loans, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans and the valuation of deferred tax assets. In connection with the determination of the allowances for loan losses and foreclosed real estate, management obtains independent appraisals for significant properties. Cash and Cash Equivalents For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash and balances due from banks and interest-bearing deposits in other banks. Time Deposits in Other Banks The Bank uses financial instruments to supplement the investment securities portfolio. Interest income is recognized as earned. Purchase premiums and discounts are recognized as part of interest income using the interest method over the terms of the investments. Realized gains and losses on the sale of time deposits in other banks are included in earnings based on the trade date and are determined using the specific identification method. Time deposits in other banks are not marked to market. Investment Securities Management determines the appropriate classification of debt securities at the time of purchase and re-evaluates Securities classified as available for sale are carried at fair value and are those securities that the Bank intends to hold for an indefinite period of time but not necessarily to maturity. Unrealized gains and losses are reported as increases or decreases in other comprehensive income. Realized gains and losses, determined on the basis of the cost of the specific securities sold, are included in earnings on a trade date basis. Premiums and discounts are recognized in interest income using a method which approximates the interest method over the terms of the securities. Declines in the fair value of available for sale securities below their cost that are deemed to be other than temporary, if any, are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, management considers (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Bank to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. Federal Home Loan Bank Stock Federal Home Loan Bank of Atlanta (“FHLB”) stock is an equity interest in the FHLB, which does not have a readily determinable fair value for purposes of U.S. GAAP related to Accounting for Certain Investments in Debt and Equity Securities, Loans Held for Sale Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value. Fair value is derived from secondary market quotations for similar instruments. Gains and losses on loan sales are recorded in non-interest non-interest The Bank enters into commitments to originate residential mortgage loans whereby the interest rate on the loan is determined prior to funding (i.e., rate lock commitment). Such rate lock commitments on mortgage loans to be sold in the secondary market are considered derivatives. The time period between the issuance of a loan commitment and closing and sale of the loan generally ranges from 30 to 90 days. The Bank protects itself from changes in interest rates through the use of best efforts forward delivery commitments, whereby the investor commits to purchase a loan at a price representing a premium on the day the borrower commits to an interest rate with the intent that they buyer/investor has assumed the interest rate risk on the loan. As a result, the Bank is not generally exposed to losses on loans sold utilizing best efforts, nor will it realize gains related to rate lock commitments due to changes in interest rates. The fair value of the rate lock commitments was considered immaterial at June 30, 2021 and December 31, 2020 and an adjustment was not recorded. Loans held for sale that are not ultimately sold, but instead are placed into the Bank’s portfolio, are reclassified as loans held for investment and recorded at fair value. Loans Loans are generally carried at the amount of unpaid principal, less the allowance for loan losses and adjusted for deferred loan origination fees and costs, which are recognized over the term of the loan as an adjustment to yield using a method that approximates the interest method. Interest on loans is accrued based on the principal amounts outstanding. It is the Bank’s policy to discontinue the accrual of interest when the principal or interest is delinquent for 90 days or more, or if collection of principal and interest in full is in doubt. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Impairment is measured on a loan by loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. The carrying value of impaired loans is based on the present value of the loan’s expected future cash flows or, alternatively, the observable market price of the loan or the fair value of the collateral. Impaired loans also include certain loans that have been modified in a troubled debt restructuring (“TDR”) to make concessions to help a borrower remain current on the loan and/or to avoid foreclosure. These concessions typically result from the Bank’s loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions. Generally, nonaccrual loans that are modified and are considered TDRs are classified as nonperforming at the time of the restructure and may only be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period, generally six months. Allowance for Loan The allowance for loan losses is established through a provision for loan losses charged to earnings. Loans are charged against the allowance for loan losses when management believes that the collectability of the principal is unlikely. The Bank maintains the allowance at a level believed, to the best of management’s knowledge, to cover all known and inherent losses in the portfolio that are both probable and reasonable to estimate at each reporting date. The evaluation process by portfolio segment includes, among other things, an analysis of delinquency trends, non-performing The establishment of the allowance for loan losses is significantly affected by management’s judgment and uncertainties, and there is likelihood that different amounts would be reported under different conditions or assumptions. The Office of the Comptroller of the Currency as an integral part of its examination process periodically reviews the allowance for loan losses and may require the Bank to make additional provisions for estimated loan losses based upon judgments different from those of management. The Bank’s policies, consistent with regulatory guidelines, provide for the classification of loans and other assets that are considered to be of lesser quality as substandard, doubtful, or loss assets. An asset is considered substandard if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Substandard assets include those assets characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. Assets classified as doubtful have all of the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Assets (or portions of assets) classified as loss, are those considered uncollectible and of such little value that their recognition as assets is not justified. Assets that do not expose us to risk sufficient to warrant classification in one of the aforementioned categories, but which possess potential weaknesses that deserve close attention, are required to be designated as special mention. While the Bank utilizes available information to recognize losses on loans, future additions to the allowances for loan losses may be necessary based on changes in economic conditions, particularly in its’ market area primarily in the state of Maryland. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance for loan losses. Such agencies may require the Bank to recognize additions to the allowance for loan losses based on their judgments about information available to them at the time of their examination. Actual loan losses may be significantly more than the allowance for loan and lease losses the Bank has established, which could have a material negative effect on our consolidated financial statements. Bank-Owned Life Insurance (“BOLI”) The Bank maintains life insurance policies on certain present and former directors. These policies are split-dollar or director insurance policies. Under the split-dollar insurance policies, the Bank pays the premiums and upon the death of the insured, the Bank will receive an amount equal to the premiums paid on the policy from the policy date to the date of death. Any remaining proceeds will be paid to the beneficiary. If the policy is surrendered before the date of death, the Bank will receive the lesser of the cash surrender value or the sum of the premiums paid on the policy from the policy date to the date of surrender. Under the director insurance policies, the Bank receives the cash surrender value if the policy is surrendered or receives all benefits payable upon the death of the insured. As of June 30, 2021 and December 31, 2020, $120,928 and $121,388, respectively, was included in other liabilities related to the split-dollar insurance policies. Premises and Equipment Land is carried at cost. Property and equipment is carried at cost less accumulated depreciation. Depreciation is computed on the straight-line method over estimated useful lives of assets. Amortization of leasehold improvements is recognized on a straight-line basis over the term of the lease or the life of the improvement, whichever is shorter. The cost of maintenance and repairs is charged to expense as incurred whereas improvements are capitalized. The range of estimated useful lives for premises and equipment are as follows: Buildings and land improvements 5 - 50 years Leasehold improvements 10 - 15 years Furniture, fixtures and equipment 3 - 10 years Automobile 5 years Foreclosed Real Estate Real estate acquired through foreclosure or other means is recorded at the fair value of the related real estate collateral at the transfer date less estimated selling costs. Losses incurred at the time of the acquisition of the property are charged to the allowance for loan losses. Subsequent reductions in the estimated fair value of the property are included in noninterest expense. Costs to maintain foreclosed real estate are expensed as incurred. Employee Stock Ownership Plan (“ESOP”) Compensation expense is recognized based on the current market price of shares committed to be released to employees. All shares released and committed to be released are deemed outstanding for purposes of earnings per share calculations. Dividends declared and paid on allocated shares held by the ESOP are charged to retained earnings. The value of unearned shares to be allocated to ESOP participants for future services not yet performed is reflected as a reduction of stockholders’ equity. Dividends declared on unallocated shares held by the ESOP are recorded as a reduction of the ESOP’s loan payment to the Company. Stock-Based Compensation Compensation cost is recognized for stock options and restricted stock awards (“RSA”) issued to employees and directors, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for RSAs. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service Income Taxes The provision for income taxes includes taxes payable for the current year and deferred income taxes. Deferred income taxes are provided for the temporary differences between financial and taxable income. Deferred income taxes and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities, using enacted tax rates in effect for the year in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management it is more likely than not that some portion of the deferred tax asset will not be realized. Deferred tax assets and liabilities are adjusted through earnings for the effects of changes in tax laws and rates on the date of enactment. Earnings per Common Share Basic earnings per share represents income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. Weighted average shares include allocated ESOP shares and ESOP shares committed to be released but exclude unallocated ESOP shares. Diluted earnings per share includes additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Off-Balance In the ordinary course of business, the Bank has entered into off-balance on-balance Concentrations of Credit Risk The Bank did not have deposits in other financial institutions in excess of amounts insured by the FDIC, as of June 30, 2021 and December 31, 2020. The Bank’s management considers deposits in excess of amounts insured by the FDIC to be a normal business risk. The Bank also maintains accounts with brokerage firms containing securities. These balances are insured up to $500,000 by the Securities Investor Protection Corporation. Emerging Growth Company The Company, as an emerging growth company (“EGC”), has elected to use the extended transition period for complying with any new or revised financial accounting standards provided pursuant to Section 13(a) of the Exchange Act. Coronavirus Aid, Relief, and Economic Security Act On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act, or CARES Act, was signed into law. The CARES Act creates a forbearance program for federally backed mortgage loans, protects borrowers from negative credit reporting due to loan accommodations related to the National Emergency, and provides financial institutions the option to temporarily suspend certain requirements under U.S. GAAP related to troubled debt restructurings for a limited period of time to account for the effects of COVID-19.

At December 31, 2020, the Bank held no investments with gross unrealized losses. The unrealized losses that existed were a result of market changes in interest rates since the original purchase. Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include (1) duration and magnitude of the decline in value, (2) the financial condition of the issuer or issuers and (3) structure of the security. An impairment loss is recognized in earnings if any of the following are true: (1) the Bank intends to sell the debt security; (2) it is more likely than not that the Bank will be required to sell the security before recovery of its amortized cost basis; or (3) the Bank does not expect to recover the entire amortized cost basis of the security. In situations where the Bank intends to sell or when it is more likely than not that the Bank will be required to sell the security, the entire impairment loss must be recognized in earnings. In all other situations, only the portion of the impairment loss representing the credit loss must be recognized in earnings, with the remaining portion being recognized in equity as a component of other comprehensive income, net of deferred tax. There were no securities pledged as of June 30, 2021 and December 31, 2020.

Loans	Note 3. Loans The Bank currently manages its credit products and respective exposure to credit losses by the following specific portfolio segments which are levels at which the Bank develops and documents its systematic methodology to determine the allowance for loan losses attributable to each respective portfolio segment. The segments are: • One-to debt-to-income non-conforming. • Home equity loans and lines of credit one-to • Construction and land development • Nonresidential real estate loans – non-owner Non-owner • Commercial loans • Consumer loans The Bank makes loans to customers primarily in the Baltimore Metropolitan Area and its surrounding counties.

Credit Quality of Loans and the Allowance for Loan Losses	Note 4. Credit Quality of Loans and the Allowance for Loan Losses The allowance for loan losses is maintained at a level to provide for losses that are probable and can be reasonably estimated. Management’s periodic evaluation of the adequacy of the allowance is based on the Bank’s past loan loss experience, known and inherent losses in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions and other relevant factors. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant change, including the amounts and timing of future cash flows expected to be received on impaired loans. The allowance consists of specific and general components. The specific component relates to loans that are classified as impaired. The general component covers non-impaired A loan is considered past due or delinquent when a contractual payment is not paid on the day it is due. A loan in considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case Loans are automatically placed on non-accrual non-accrual non-accrual charge-off The following tables summarize the activity in the allowance for losses for the three and six months ended June 30, 2021 and 2020 and the distribution of the allowance for loan losses and loans receivable by loan portfolio class and impairment method as of June 30, 2021 and June 30 As of June 30, 2021 One –to Four-Family Home Equity Construction and Land Nonresidential Commercial Consumer Total Allowance for loans losses: Beginning Balance – April 1, 2021 $ 317,951 $ 44,473 $ 217,705 $ 1,065,699 $ 77,183 $ 4,205 $ 1,727,216 Charge-offs — — — — — — — Recoveries — — — — — — — Provision for loan losses (34,415 ) (5,798 ) (31,476 ) (32,282 ) 4,264 (293 ) (100,000 ) Ending Balance – June 30, 2021 $ 283,536 $ 38,675 $ 186,229 $ 1,033,417 $ 81,447 $ 3,912 $ 1,627,216 Beginning Balance – January 1, 2021 $ 339,817 $ 64,350 $ 206,362 $ 1,043,596 $ 68,380 $ 4,711 $ 1,727,216 Charge-offs — — — — — — — Recoveries — — — — — — — Provision for loan losses (56,281 ) (25,675 ) (20,133 ) (10,179 ) 13,067 (799 ) (100,000 ) Ending Balance – June 30, 2021 $ 283,536 $ 38,675 $ 186,229 $ 1,033,417 $ 81,447 $ 3,912 $ 1,627,216 Ending balance: individually evaluated for impairment $ 7,172 $ 397 $ — $ — $ — $ — $ 7,569 Ending balance: collectively evaluated for impairment $ 276,364 $ 38,278 $ 186,229 $ 1,033,417 $ 81,447 $ 3,912 $ 1,619,647 Loans: Ending balance $ 62,354,612 $ 4,355,135 $ 11,355,435 $ 59,667,160 $ 12,425,437 $ 277,427 $ 150,435,206 Ending balance: individually evaluated for impairment $ 321,420 $ 54,221 $ — $ — $ — $ — $ 375,641 Ending balance: collectively evaluated for impairment $ 62,033,192 $ 4,300,914 $ 11,355,435 $ 59,667,160 $ 12,425,437 $ 277,427 $ 150,059,565 As of June 30, 2020 One –to Four-Family Home Equity Construction and Land Nonresidential Commercial Consumer Unallocated Total Allowance for loans losses: Beginning Balance – April 1, 2020 $ 380,229 $ 64,843 $ 206,782 $ 809,018 $ 67,499 $ 5,527 $ 16,953 $ 1,550,851 Charge-offs — — — — — — — — Recoveries — — — — — — — — Provision for loan losses 12,235 4,556 (3,270 ) 56,742 23,381 (354 ) 56,710 150,000 Ending Balance – June 30, 2020 $ 392,464 $ 69,399 $ 203,512 $ 865,760 $ 90,880 $ 5,173 $ 73,663 $ 1,700,851 Beginning Balance – January 1, 2020 $ 331,605 $ 62,603 $ 179,541 $ 683,453 $ 55,571 $ 6,950 $ 59,427 $ 1,379,150 Charge-offs — — (263 ) — — (3,633 ) — (3,896 ) Recoveries — 597 — — — — — 597 Provision for loan losses 60,859 6,199 24,234 182,307 35,309 1,856 14,236 325,000 Ending Balance – June 30, 2020 $ 392,464 $ 69,399 $ 203,512 $ 865,760 $ 90,880 $ 5,173 $ 73,663 $ 1,700,851 Ending balance: individually evaluated for impairment $ — $ 284 $ — $ — $ — $ — $ — $ 284 Ending balance: collectively evaluated for impairment $ 392,464 $ 69,115 $ 203,512 $ 865,760 $ 90,880 $ 5,173 $ 73,663 $ 1,700,567 Loans: Ending balance $ 73,149,556 $ 7,412,377 $ 8,965,295 $ 61,143,526 $ 15,510,905 $ 407,304 $ 166,588,963 Ending balance: individually evaluated for impairment $ 470,949 $ 59,769 $ — $ 1,544,238 $ — $ — $ 2,074,956 Ending balance: collectively evaluated for impairment $ 72,678,607 $ 7,352,608 $ 8,965,295 $ 59,599,288 $ 15,510,905 $ 407,304 $ 164,514,007 As part of the ongoing monitoring of the credit quality of the Bank’s loan portfolio, management tracks certain credit quality indicators including trends related to the risk grade of classified loans, net chargeoffs, nonperforming loans, credit scores, and the general economic conditions in the Bank’s market area. The Bank utilizes an internal rating system to monitor the credit quality of the overall loan portfolio. A description of the general characteristics is as follows: • Pass • Special mention • Substandard • Doubtful non-accrual • Loss charged-off When assets are classified as impaired, the Bank allocates a portion of the related general loss allowances to such assets as the Bank deems prudent. Determinations as to the classification of assets and the amount of loss allowances are subject to review by our principal federal regulator, the Office of the Comptroller of the Currency, which can require that we establish additional loss allowances. The Bank regularly reviews its asset portfolio to determine whether any assets require classification in accordance with applicable regulations.

At June 30, 2021, the Bank had four loans on non-accrual non-accrual The Bank accounts for impaired loans under generally accepted accounting principles. An impaired loan generally is one for which it is probable, based on current information, that the lender will not collect all the amounts due under the contractual terms of the loan. Loans are individually evaluated for impairment. When the Bank classifies a problem asset as impaired, it provides a specific reserve for that portion of the asset that is deemed uncollectible based on the present value of expected future cash flows discounted at the loan’s original effective interest rate, or based on the loan’s observable market price or fair value of the collateral if the loan is collateral dependent. The following table is a summary of impaired loans for the three and six months ended June 30, 2021 and 2020 and the year ended December 31, 2020: Impaired Loans at June 30, 2021 Three Months Ended Six Months Ended Recorded Unpaid Related Average Interest Average Interest With no related allowance recorded: One-to $ 232,064 $ 235,180 $ — $ 232,270 $ 413 $ 232,270 $ 413 Home equity loans and lines of credit 20,621 20,621 — 20,621 — 20,621 — With an allowance recorded: One-to $ 89,356 $ 89,356 $ 7,172 $ 89,723 $ 1,011 $ 90,085 $ 2,030 Home equity loans and lines of credit 33,600 33,600 397 33,937 567 34,584 1,053 Total One-to $ 321,420 $ 324,536 $ 7,172 $ 321,993 $ 1,424 $ 322,355 $ 2,443 Home equity loans and lines of credit 54,221 54,221 397 54,557 567 55,205 1,053 Impaired Loans at June 30, 2020 Three Months Ended Six Months Ended Recorded Unpaid Related Average Interest Average Interest With no related allowance recorded: One-to $ 470,949 $ 472,220 $ — $ 472,139 $ 4,686 $ 474,116 $ 9,180 Home equity loans and lines of credit 22,912 22,912 — 22,912 170 23,141 170 Nonresidential 1,544,238 1,544,238 — 1,552,496 16,883 1,563,028 40,349 With an allowance recorded: Home equity loans and lines of credit $ 36,857 $ 36,857 $ 284 $ 37,980 $ 500 $ 38,650 $ 1,147 Total One-to $ 470,949 $ 472,220 $ — $ 472,139 $ 4,686 $ 474,116 $ 9,180 Home equity loans and lines of credit 59,769 59,769 284 60,891 670 61,791 1,317 Nonresidential 1,544,238 1,544,238 — 1,552,496 16,883 1,563,028 40,349 December 31, 2020 Recorded Unpaid Related Average Interest With no related allowance recorded: One-to $ 97,032 $ 98,970 $ — $ 97,804 $ 1,927 With an allowance recorded: One-to $ 90,813 $ 90,813 $ 7,501 $ 88,012 $ 4,019 Home equity loans and lines of credit 35,568 35,568 97 38,005 2,238 Total One-to $ 187,845 $ 189,783 $ 7,501 $ 185,816 $ 5,946 Home equity loans and lines of credit 35,568 35,568 97 38,005 2,238 Impaired loans also include certain loans that have been modified in a TDR to make concessions to help a borrower remain current on the loan and/or to avoid foreclosure. These concessions typically result from the Bank’s loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions. Generally, nonaccrual loans that are modified and are considered TDRs are classified as nonperforming at the time of the restructure and may only be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period, generally six months. A summary of TDRs at June 30, 2021 and December 31, 2020 are as follows: June 30, 2021 Number of Performing Nonperforming Total One-to 1 $ 89,356 $ — $ 89,356 Home equity loans and lines of credit 1 33,600 — 33,600 2 $ 122,956 $ — $ 122,956 December 31, 2020 Number of Performing Nonperforming Total One-to 1 $ — $ 90,813 $ 90,813 Home equity loans and lines of credit 1 35,568 — 35,568 2 $ 35,568 $ 90,813 $ 126,381 The Bank had two TDRs at June 30, 2021 totaling $122,956 and two TDRs at December 31, 2020 totaling $126,381. The Bank has no commitments to loan additional funds to borrowers whose loans have been modified. There were no nonperforming TDRs reclassified to nonperforming loans during the three and six months ended June 30, 2021 and 2020. A default is considered to have occurred once the TDR is past due 90 days or more, or it has been placed on nonaccrual. If loans modified in a TDR subsequently default, the Bank evaluates the loan for possible further impairment. The allowance may be increased, adjustments may be made in the allocation of the allowance, or partial charge-offs may be taken to further write-down the carrying value of the loan.

Employee Stock Ownership Plan	Note 8. Employee Stock Ownership Plan In connection with the Bank’s mutual to stock conversion in September 2018, the Bank established the Chesapeake Bank of Maryland Employee Stock Ownership Plan (“ESOP”) for all eligible employees. The ESOP purchased 338,560 shares of Company common stock in the Company’s initial public offering at $10.00 per share with the proceeds of a ten (10) year loan from the Company. The Bank intends to make annual contributions to the ESOP that at a minimum will permit the ESOP to repay the principal and interest due on the ESOP debt. However, the Bank may prepay the principal of the note, partially or in full and without penalty or premium at any time and from time to time without prior notice to the holder. Any dividends declared on Company common stock held by the ESOP and not allocated to the account of a participant can be used to repay the loan. As the ESOP loan is repaid, shares of Company common stock pledged as collateral for the loan are released from the loan suspense account for allocation to Plan participants on the basis of each active participant’s proportional share of compensation. Participants vest 100% in their ESOP allocations after three years of service. In connection with the implementation of the ESOP, participants were given credit for past service with the Bank for vesting purposes. Participants will become fully vested upon age 65, death or disability, a change in control, or termination of the ESOP. Generally, participants will receive distributions from the ESOP upon separation from service. The plan reallocates any unvested shares of common stock forfeited upon termination of employment among the remaining participants in the plan. The ESOP compensation expense was $120,363 and $238,476 and for the three and six months ended June 30, 2021 and $107,493 and $220,064 for the three and six months ended June 30, 2020. This amount represents the average fair market value of the shares of Company common stock allocated or committed to be released as of that date. The difference between the market price and the cost of shares committed to be released is recorded as an adjustment to additional paid-in

Participants will vest in their share awards at a rate of 20% per year over a five year period, beginning one year after the date of the plan share award. If service to the Company is terminated for any reason other than death, disability or change in control, the unvested share awards will be forfeited.

Earnings Per Common Share	Note 11. Earnings Per Common Share Basic earnings per share is calculated by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Net income available to common stockholders is net income to the Company. Unallocated common shares held by the ESOP are not included in the weighted average number of common shares outstanding for purposes of calculating earnings per share until they are committed to be released. Basic earnings per share excludes dilution and is computed by dividing net income by weighted average number of common shares outstanding during the period.

Nature of Operations	CBM Bancorp, Inc. (“CBM Bancorp” or “Company”) is the holding company for Chesapeake Bank of Maryland (“Bank”) and was formed in connection with the conversion of the Bank from the mutual to the stock form of organization. On September 27, 2018, the mutual to stock conversion of the Bank was completed and the Company became the parent holding company for the Bank. Shares of the Company began trading on the Nasdaq Capital Market on September 28, 2018. The Company is subject to regulation by the Board of Governors of the Federal Reserve System. CBM Bancorp’s primary business is the ownership and operation of the Bank, a community-oriented federal stock savings bank regulated by the Office of the Comptroller of the Currency. The Bank’s primary business activity is the acceptance of deposits from the general public and using the proceeds for loan originations and investments. The Bank is subject to competition from other financial institutions. The Bank is subject to the regulations of certain federal agencies and undergoes periodic examinations by the regulatory authorities. In accordance with federal and state regulations, at the time of the conversion from mutual to stock form, the Bank substantially restricted retained earnings by establishing a liquidation account. The liquidation account will be maintained for the benefit of eligible account holders who continue to maintain their accounts at the Bank after the conversion. The liquidation account will be reduced annually to the extent that eligible account holders have reduced their qualifying deposits. Subsequent increases will not restore an eligible account holder’s interest in the liquidation account. In the event of a complete liquidation of the Bank, each account holder will be entitled to receive a distribution in an amount proportionate to the adjusted qualifying account balances then held. The Company may not pay a dividend on, or repurchase any of, its capital stock, if the effect thereof would cause retained earnings to be reduced below the liquidation account amount or regulatory capital requirements. In addition, the Company is subject to certain other regulations restricting the payment of dividends on, and the repurchase of, its capital stock.
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q S-X 10-K
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of CBM Bancorp, Inc. and the Bank, its wholly owned subsidiary. Material intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for losses on loans, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans and the valuation of deferred tax assets. In connection with the determination of the allowances for loan losses and foreclosed real estate, management obtains independent appraisals for significant properties.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash and balances due from banks and interest-bearing deposits in other banks.
Time Deposits in Other Banks	Time Deposits in Other Banks The Bank uses financial instruments to supplement the investment securities portfolio. Interest income is recognized as earned. Purchase premiums and discounts are recognized as part of interest income using the interest method over the terms of the investments. Realized gains and losses on the sale of time deposits in other banks are included in earnings based on the trade date and are determined using the specific identification method. Time deposits in other banks are not marked to market.
Investment Securities	Investment Securities Management determines the appropriate classification of debt securities at the time of purchase and re-evaluates Securities classified as available for sale are carried at fair value and are those securities that the Bank intends to hold for an indefinite period of time but not necessarily to maturity. Unrealized gains and losses are reported as increases or decreases in other comprehensive income. Realized gains and losses, determined on the basis of the cost of the specific securities sold, are included in earnings on a trade date basis. Premiums and discounts are recognized in interest income using a method which approximates the interest method over the terms of the securities. Declines in the fair value of available for sale securities below their cost that are deemed to be other than temporary, if any, are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, management considers (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Bank to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock Federal Home Loan Bank of Atlanta (“FHLB”) stock is an equity interest in the FHLB, which does not have a readily determinable fair value for purposes of U.S. GAAP related to Accounting for Certain Investments in Debt and Equity Securities,
Loans Held for Sale	Loans Held for Sale Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value. Fair value is derived from secondary market quotations for similar instruments. Gains and losses on loan sales are recorded in non-interest non-interest The Bank enters into commitments to originate residential mortgage loans whereby the interest rate on the loan is determined prior to funding (i.e., rate lock commitment). Such rate lock commitments on mortgage loans to be sold in the secondary market are considered derivatives. The time period between the issuance of a loan commitment and closing and sale of the loan generally ranges from 30 to 90 days. The Bank protects itself from changes in interest rates through the use of best efforts forward delivery commitments, whereby the investor commits to purchase a loan at a price representing a premium on the day the borrower commits to an interest rate with the intent that they buyer/investor has assumed the interest rate risk on the loan. As a result, the Bank is not generally exposed to losses on loans sold utilizing best efforts, nor will it realize gains related to rate lock commitments due to changes in interest rates. The fair value of the rate lock commitments was considered immaterial at June 30, 2021 and December 31, 2020 and an adjustment was not recorded. Loans held for sale that are not ultimately sold, but instead are placed into the Bank’s portfolio, are reclassified as loans held for investment and recorded at fair value.
Loans	Loans Loans are generally carried at the amount of unpaid principal, less the allowance for loan losses and adjusted for deferred loan origination fees and costs, which are recognized over the term of the loan as an adjustment to yield using a method that approximates the interest method. Interest on loans is accrued based on the principal amounts outstanding. It is the Bank’s policy to discontinue the accrual of interest when the principal or interest is delinquent for 90 days or more, or if collection of principal and interest in full is in doubt. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Impairment is measured on a loan by loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. The carrying value of impaired loans is based on the present value of the loan’s expected future cash flows or, alternatively, the observable market price of the loan or the fair value of the collateral. Impaired loans also include certain loans that have been modified in a troubled debt restructuring (“TDR”) to make concessions to help a borrower remain current on the loan and/or to avoid foreclosure. These concessions typically result from the Bank’s loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions. Generally, nonaccrual loans that are modified and are considered TDRs are classified as nonperforming at the time of the restructure and may only be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period, generally six months.
Allowance for Loan Losses	Allowance for Loan The allowance for loan losses is established through a provision for loan losses charged to earnings. Loans are charged against the allowance for loan losses when management believes that the collectability of the principal is unlikely. The Bank maintains the allowance at a level believed, to the best of management’s knowledge, to cover all known and inherent losses in the portfolio that are both probable and reasonable to estimate at each reporting date. The evaluation process by portfolio segment includes, among other things, an analysis of delinquency trends, non-performing The establishment of the allowance for loan losses is significantly affected by management’s judgment and uncertainties, and there is likelihood that different amounts would be reported under different conditions or assumptions. The Office of the Comptroller of the Currency as an integral part of its examination process periodically reviews the allowance for loan losses and may require the Bank to make additional provisions for estimated loan losses based upon judgments different from those of management. The Bank’s policies, consistent with regulatory guidelines, provide for the classification of loans and other assets that are considered to be of lesser quality as substandard, doubtful, or loss assets. An asset is considered substandard if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Substandard assets include those assets characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. Assets classified as doubtful have all of the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Assets (or portions of assets) classified as loss, are those considered uncollectible and of such little value that their recognition as assets is not justified. Assets that do not expose us to risk sufficient to warrant classification in one of the aforementioned categories, but which possess potential weaknesses that deserve close attention, are required to be designated as special mention. While the Bank utilizes available information to recognize losses on loans, future additions to the allowances for loan losses may be necessary based on changes in economic conditions, particularly in its’ market area primarily in the state of Maryland. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance for loan losses. Such agencies may require the Bank to recognize additions to the allowance for loan losses based on their judgments about information available to them at the time of their examination. Actual loan losses may be significantly more than the allowance for loan and lease losses the Bank has established, which could have a material negative effect on our consolidated financial statements.
Bank-Owned Life Insurance ("BOLI")	Bank-Owned Life Insurance (“BOLI”) The Bank maintains life insurance policies on certain present and former directors. These policies are split-dollar or director insurance policies. Under the split-dollar insurance policies, the Bank pays the premiums and upon the death of the insured, the Bank will receive an amount equal to the premiums paid on the policy from the policy date to the date of death. Any remaining proceeds will be paid to the beneficiary. If the policy is surrendered before the date of death, the Bank will receive the lesser of the cash surrender value or the sum of the premiums paid on the policy from the policy date to the date of surrender. Under the director insurance policies, the Bank receives the cash surrender value if the policy is surrendered or receives all benefits payable upon the death of the insured. As of June 30, 2021 and December 31, 2020, $120,928 and $121,388, respectively, was included in other liabilities related to the split-dollar insurance policies.
Premises and Equipment	Premises and Equipment Land is carried at cost. Property and equipment is carried at cost less accumulated depreciation. Depreciation is computed on the straight-line method over estimated useful lives of assets. Amortization of leasehold improvements is recognized on a straight-line basis over the term of the lease or the life of the improvement, whichever is shorter. The cost of maintenance and repairs is charged to expense as incurred whereas improvements are capitalized. The range of estimated useful lives for premises and equipment are as follows: Buildings and land improvements 5 - 50 years Leasehold improvements 10 - 15 years Furniture, fixtures and equipment 3 - 10 years Automobile 5 years
Foreclosed Real Estate	Foreclosed Real Estate Real estate acquired through foreclosure or other means is recorded at the fair value of the related real estate collateral at the transfer date less estimated selling costs. Losses incurred at the time of the acquisition of the property are charged to the allowance for loan losses. Subsequent reductions in the estimated fair value of the property are included in noninterest expense. Costs to maintain foreclosed real estate are expensed as incurred.
Employee Stock Ownership Plan ("ESOP")	Employee Stock Ownership Plan (“ESOP”) Compensation expense is recognized based on the current market price of shares committed to be released to employees. All shares released and committed to be released are deemed outstanding for purposes of earnings per share calculations. Dividends declared and paid on allocated shares held by the ESOP are charged to retained earnings. The value of unearned shares to be allocated to ESOP participants for future services not yet performed is reflected as a reduction of stockholders’ equity. Dividends declared on unallocated shares held by the ESOP are recorded as a reduction of the ESOP’s loan payment to the Company.
Stock-Based Compensation	Stock-Based Compensation Compensation cost is recognized for stock options and restricted stock awards (“RSA”) issued to employees and directors, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for RSAs. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service
Income Taxes	Income Taxes The provision for income taxes includes taxes payable for the current year and deferred income taxes. Deferred income taxes are provided for the temporary differences between financial and taxable income. Deferred income taxes and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities, using enacted tax rates in effect for the year in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management it is more likely than not that some portion of the deferred tax asset will not be realized. Deferred tax assets and liabilities are adjusted through earnings for the effects of changes in tax laws and rates on the date of enactment.
Earnings per Common Share	Earnings per Common Share Basic earnings per share represents income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. Weighted average shares include allocated ESOP shares and ESOP shares committed to be released but exclude unallocated ESOP shares. Diluted earnings per share includes additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance.
Off-Balance Sheet Financial Instruments	Off-Balance In the ordinary course of business, the Bank has entered into off-balance on-balance
Concentrations of Credit Risk	Concentrations of Credit Risk The Bank did not have deposits in other financial institutions in excess of amounts insured by the FDIC, as of June 30, 2021 and December 31, 2020. The Bank’s management considers deposits in excess of amounts insured by the FDIC to be a normal business risk. The Bank also maintains accounts with brokerage firms containing securities. These balances are insured up to $500,000 by the Securities Investor Protection Corporation.
Emerging Growth Company	Emerging Growth Company The Company, as an emerging growth company (“EGC”), has elected to use the extended transition period for complying with any new or revised financial accounting standards provided pursuant to Section 13(a) of the Exchange Act.
Coronavirus Aid, Relief, and Economic Security Act	Coronavirus Aid, Relief, and Economic Security Act On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act, or CARES Act, was signed into law. The CARES Act creates a forbearance program for federally backed mortgage loans, protects borrowers from negative credit reporting due to loan accommodations related to the National Emergency, and provides financial institutions the option to temporarily suspend certain requirements under U.S. GAAP related to troubled debt restructurings for a limited period of time to account for the effects of COVID-19.
