Item 1. Business.

CFSB Bancorp, Inc.

CFSB Bancorp, Inc. (“CFSB Bancorp” or the “Company”) is a federal corporation that was formed in January 2022 to become the bank holding company of Colonial Federal Savings Bank (the “Bank”) as part of the mutual holding company reorganization of the Bank. Since being incorporated, other than holding the common stock of the Bank, CFSB Bancorp retaining approximately 50% of the net cash proceeds of the stock offering, making a loan to the employee stock ownership plan of the Bank, CFSB Bancorp has not engaged in any other business activities.

CFSB Bancorp completed its stock offering in connection with the mutual holding company reorganization of the Bank on January 12, 2022. The Company sold 2,804,306 shares of common stock at $10.00 per share for gross proceeds of $28.0 million. In connection with the reorganization, the Company also contributed 130,433 shares of common stock and $250,000 in cash to the Colonial Federal Savings Bank Charitable Foundation and issued 3,586,903 shares of common stock to 15 Beach, MHC, its federally-chartered mutual holding company. Shares of the Company’s common stock began trading on January 13, 2022 on The NASDAQ Stock Market under the trading symbol “CFSB.”

CFSB Bancorp, as the holding company of the Bank, is authorized to pursue other business activities permitted by applicable laws and regulations, which may include the acquisition of banking and financial services companies. We currently have no agreements to acquire other financial institutions or financial services companies, although we may determine to do so in the future.

CFSB Bancorp’s cash flows will depend on earnings from the investment of the net offering proceeds and from any dividends it receives from the Bank. The Bank is subject to regulatory limitations on the amount of dividends that it may pay. Initially, CFSB Bancorp will not own or lease any property, but instead will pay the Bank for the use of its premises, furniture and equipment. We intend to employ as officers of CFSB Bancorp only persons who are officers of the Bank. However, we will use the support staff of the Bank from time to time. We will pay the Bank for the time the Bank employees devote to CFSB Bancorp; however, these individuals will not be separately compensated by CFSB Bancorp. CFSB Bancorp may hire additional employees, as appropriate, to the extent it expands its business in the future.

15 Beach, MHC

15 Beach, MHC was formed in January 2022 as a federally-chartered mutual holding company in connection with the reorganization of the Bank into the “two-tier” mutual holding company form of organization. 15 Beach, MHC

will, for as long as it is in existence, own a majority of the outstanding shares of CFSB Bancorp’s common stock. As a mutual holding company, 15 Beach, MHC is a non-stock company.

15 Beach, MHC’s principal assets are the common stock of CFSB Bancorp it received in the reorganization and offering and $100,000 cash in initial capitalization. Presently, it is expected that the only business activity of 15 Beach, MHC is to own a majority of CFSB Bancorp’s common stock. 15 Beach, MHC is authorized to engage in any other business activities that are permissible for mutual holding companies under federal law, including investing in loans and securities. 15 Beach, MHC is subject to comprehensive regulation and examination by the Federal Reserve Board.

Colonial Federal Savings Bank

We conduct our operations from our three full-service banking offices and one limited-service banking office located in Norfolk County. We consider our primary lending market area to be Norfolk and Plymouth Counties; however, we occasionally make loans secured by properties located outside of our primary lending market. Our business consists primarily of taking deposits from the general public and investing those deposits, together with funds generated from operations, in one- to four-family residential real estate loans and, to a lesser extent, multi-family real estate loans, commercial real estate loans, second mortgage loans, home equity lines of credit, and consumer loans. Subject to market conditions, we will continue our focus on growing our balance sheet and improving profitability by continuing to originate one- to four-family residential mortgage loans and increasing the origination of multi-family and commercial real estate loans.

At June 30, 2022, we had total assets of $366.2 million, total deposits of $287.1 million and total equity of $74.3 million. We had net income of $442,000 for the year ended June 30, 2022 compared to net income of $1.4 million for the year ended June 30, 2021.

Market Area

We conduct our operations from our three full-service banking offices and one limited-service banking office located in Norfolk County, Massachusetts. We consider our primary lending market area to be Norfolk and Plymouth Counties, Massachusetts; however, we occasionally make loans secured by properties located outside of our primary lending market.

Norfolk County is located directly south of the city of Boston, Massachusetts. The county includes 28 eastern Massachusetts communities, all of which are residential suburbs of Boston. Norfolk County is the wealthiest county in the Commonwealth of Massachusetts and is characterized by a high concentration of white-collar professionals who work in the Boston Metropolitan Statistical Area. According to the United States Census Bureau, the total population of Norfolk County was 724,505 as of July 1, 2021. The annual population growth rate within Norfolk County has decreased 0.2% from 2020 to 2021.

According to the United States Census Bureau from 2016 through 2020:

Additionally, according to the U.S. Bureau of Labor Statistics, the unemployment rate at June 2022 was 3.1% for Norfolk County, compared to 3.7% for Massachusetts and 3.5% for the United States.

Competition

We face significant competition within our market both in making loans and attracting deposits. Our market area has a high concentration of financial institutions, including large money centers and regional banks, community banks and credit unions. Some of our competitors offer products and services that we currently do not offer, such as trust services and private banking. Our competition for loans and deposits comes principally from commercial banks, savings institutions, mortgage banking firms, consumer finance companies and credit unions. We face additional competition for deposits from short-term money market funds, brokerage firms, mutual funds and insurance companies.

As of June 30, 2021 (the latest date for which information is available), our market share was 0.78% of total deposits in Norfolk County, Massachusetts, making us the 23rd largest out of 43 banks operating in Norfolk County.

Lending Activities

Our principal lending activity is in one- to four-family residential real estate loans, and, to a lesser extent, multi-family real estate loans, commercial real estate loans, second mortgage loans, home equity lines of credit and consumer loans. Subject to market conditions and our asset-liability analysis, we expect to increase our focus on the origination of multi-family and commercial real estate loans in an effort to diversify our overall loan portfolio and increase the overall yield earned on our portfolio. We compete by focusing on personalized service for consumers as well as businesses. Due to our structure, we are able to move quickly on customer requests and are able to price competitively compared to our competitors. Our responsiveness has historically enabled us to grow and retain our customer base.

Loan Portfolio Composition. The following table sets forth the composition of our loan portfolio by type of loan at the dates indicated. At June 30, 2022 and 2021, we had no loans held for sale.

Contractual Maturities. The following tables set forth the contractual maturities of our loan portfolio at June 30, 2022. Demand loans, loans having no stated repayment schedule or maturity, and overdraft loans are reported as being due in one year or less. The tables present contractual maturities and do not reflect repricing or the effect of prepayments. Actual maturities may differ.

Fixed Versus Adjustable-Rate Loans. The following table sets forth our fixed- and adjustable-rate loans at June 30, 2022 that are contractually due after June 30, 2023.

One- to Four-Family Residential Real Estate Lending. Our historical primary lending activity has been the origination of one- to four-family, owner-occupied, residential mortgage loans, virtually all of which are secured by properties located in our market area. At June 30, 2022, one- to four-family residential real estate loans totaled $141.1 million, or 80.8% of our total loan portfolio. The average principal loan balance of our one- to four-family residential real estate loans was $241,000 at June 30, 2022.

We currently offer one- to four-family residential real estate loans with terms of up to 30 years. The one- to four-family residential real estate loans that we originate are generally underwritten to Fannie Mae and Freddie Mac guidelines. We currently retain in our portfolio all of the one- to four-family residential real estate loans we originate. We primarily originate fixed-rate one- to four-family residential real estate loans, but, on a much more limited basis, also originate adjustable-rate loans. At June 30, 2022, $133.0 million, or 94.3%, of our one- to four-family residential real estate loans had fixed rates of interest, and $8.0 million, or 5.7%, of our one- to four-family residential real estate loans, had adjustable rates of interest. One- to four-family residential real estate loans often remain outstanding for significantly shorter periods than their contractual terms because borrowers have the right to refinance or prepay their loans. We generally limit the loan-to-value ratios of our mortgage loans to 80% of the sales price or appraised value, whichever is lower.

6

Our adjustable-rate one- to four-family residential real estate loans carry terms to maturity ranging from 10 to 30 years and generally have fixed rates for initial terms of one, three or five years, and adjust annually thereafter at a margin, which in recent years has been tied to the one-year constant maturity U.S. Treasury rate. The maximum amount by which the interest rate may be increased or decreased is, subject to a contractual floor (which is generally the initial interest rate on the loan), generally 2% annually, with a lifetime interest rate cap of generally 6% over the initial interest rate of the loan.

Although adjustable-rate mortgage loans may reduce to an extent our vulnerability to changes in market interest rates because they periodically re-price, as interest rates increase the required payments due from the borrower also increase (subject to rate caps), increasing the potential for default by the borrower. At the same time, the ability of the borrower to repay the loan and the marketability of the underlying collateral may be adversely affected by higher interest rates. Upward adjustments of the contractual interest rate are also limited by our maximum periodic and lifetime rate adjustments. As a result, the effectiveness of adjustable-rate mortgage loans in compensating for changes in market interest rates may be limited.

At June 30, 2022, $18.8 million, or 13.3%, of the one- to four-family residential real estate loan portfolio, was secured by non-owner-occupied properties. We generally originate these loans to individuals to whom we have had a previous borrowing relationship. Generally, we require personal guarantees on these properties if the loan is made to an entity other than individual borrowers. We will not make loans in excess of 80% loan-to-value on non-owner- occupied properties.

Our construction loans are generally one- to four-family residential owner occupied properties where the borrower is improving the property. Construction credit risk is affected by cost overruns and market conditions. At June 30, 2022 $375,000, or 0.3% of our one- to four- family residential real estate loans were construction loans.

We have not offered “interest only” mortgage loans on permanent one- to four-family residential real estate loans (where the borrower pays interest for an initial period, after which the loan converts to a fully amortizing loan). We also have not offered loans that provide for negative amortization of principal, such as “Option ARM” loans, where the borrower can pay less than the interest owed on the loan, resulting in an increased principal balance during the life of the loan. We have not offered “Alt-A” loans (i.e., loans that generally target borrowers with better credit scores who borrow with alternative documentation such as little or no verification of income). We also do not originate subprime loans to customers with weakened credit histories.

We require title insurance on all of our one- to four-family residential real estate mortgage loans, and we also require that borrowers maintain fire and extended coverage casualty insurance (and, if appropriate, flood insurance) in an amount at least equal to the lesser of the loan balance or the replacement cost of the improvements. We do not conduct environmental testing on residential real estate mortgage loans unless specific concerns for hazards are identified in the appraisal conducted in connection with the origination of the loan.

When underwriting residential real estate loans, we review and verify each loan applicant’s employment, income and credit history and, if applicable, our experience with the borrower. Our policy is to obtain credit reports on all borrowers and guarantors. We also obtain tax returns and financial statements for non-owner-occupied loans. Generally, all properties securing residential real estate loans are appraised by independent appraisers.

Multi-Family and Commercial Real Estate Lending. At June 30, 2022, multi-family real estate loans totaled $14.3 million, or 8.2% of our loan portfolio. Our multi-family real estate loans are generally secured by properties consisting of five or more rental units within our market area. At June 30, 2022, commercial real estate loans totaled $14.8 million, or 8.5% of our loan portfolio. Our commercial real estate loans are generally secured by office buildings, small retail facilities, mixed-use facilities and warehouses within our market area. We currently offer multi-family and commercial real estate loans with terms of up to 30 years. We currently retain in our portfolio all of the multi-family and commercial real estate loans we originate.

We primarily originate adjustable-rate multi-family and commercial real estate loans, but we do, on a much more limited basis, originate fixed-rate loans. At June 30, 2022, $12.3 million, or 86.0%, of multi-family real estate loans had adjustable rates of interest, and $2.0 million, or 14.0%, of our multi-family real estate loans, had fixed rates of interest. At June 30, 2022, $12.8 million, or 86.5%, of commercial real estate loans had adjustable rates of interest, and $2.0 million, or 13.5%, of our commercial real estate loans, had fixed rates of interest. Interest rates on our adjustable-rate multi-family and commercial real estate loans are generally fixed for the first five years and adjust annually thereafter based on the one-year U.S. Treasury constant maturity rate, plus a margin.

7

At June 30, 2022, the average loan size of our outstanding multi-family real estate loans was $622,000, and our largest multi-family residential real estate loan had an outstanding balance of $1.9 million and is secured by an apartment building located in our primary market area. At June 30, 2022, this loan was performing according to its original terms. At June 30, 2022, the average loan size of our outstanding commercial real estate loans was $476,000, and our largest commercial real estate loan had an outstanding balance of $2.4 million and is secured by three properties related to an ambulance dispatching and maintenance center located in our primary market area. At June 30, 2022, this loan was performing according to its original terms.

We consider a number of factors in originating multi-family and commercial real estate loans. We evaluate the qualifications, income level and financial condition of the borrower, including project-level and global cash flows, credit history, and management expertise, as well as the value and condition of the property securing the loan. When evaluating the qualifications of the borrower, we consider the financial resources of the borrower, the borrower’s experience in owning or managing similar property and the borrower’s payment history with us and other financial institutions. In evaluating the property securing the loan, the factors we consider include the net operating income of the mortgaged property before debt service and depreciation, the ratio of the loan amount to the appraised value of the mortgaged property and the debt service coverage ratio (the ratio of net operating income to debt service). We generally require a debt service ratio of at least 1.20x. Multi-family and commercial real estate loans have loan-to-value ratios of up to 80% of the appraised value of the property securing the loans. When underwriting multi-family and commercial real estate loans, we review and verify each loan applicant’s employment, income and credit history. Our policy is to obtain credit reports, financial statements and tax returns on all borrowers and guarantors. Generally, all properties securing real estate loans are appraised by independent appraisers. Generally, we require personal guaranties from the principals on the loans.

Multi-family and commercial real estate loans entail greater credit risks compared to one- to four-family residential real estate loans because they typically involve larger loan balances concentrated with single borrowers or groups of related borrowers. In addition, the payment of loans secured by income-producing properties typically depends on the successful operation of the property, as repayment of the loan generally is dependent, in large part, on sufficient income from the property to cover operating expenses and debt service. Changes in economic conditions that are not in the control of the borrower or lender could affect the value of the collateral for the loan or the future cash flow of the property. Additionally, any decline in real estate values may be more pronounced for commercial real estate than residential properties. If we foreclose on a multi-family or commercial real estate loan, the marketing and liquidation period to convert the real estate asset to cash can be a lengthy process with substantial holding costs. In addition, vacancies, deferred maintenance, repairs and market stigma can result in prospective buyers expecting sale price concessions to offset their real or perceived economic losses for the time it takes them to return the property to profitability. Depending on the individual circumstances, initial charge-offs and subsequent losses on multi-family and commercial real estate loans can be both unpredictable and substantial.

Second Mortgage Loans and Home Equity Lines of Credit. At June 30, 2022, second mortgage loans and home equity lines of credit totaled $2.0 million, or 1.1% of our loan portfolio. Second mortgage loans and home equity lines of credit are multi-purpose loans used to finance various home or personal needs for which a one- to four-family primary or secondary residence serves as collateral. We generally originate home equity lines of credit on owner-occupied properties with adjustable rates of interest based on the prime interest rate published in The Wall Street Journal, plus a margin. We generally originate home equity lines of credit with a maximum loan-to-value ratio of 80% (including the value of the underlying mortgage loan) and with terms of up to 20 years. We originate second mortgage loans on owner-occupied properties with fixed rates of interest. We generally originate these loans with a maximum loan-to-value ratio of 80% (including the value of the underlying mortgage loan) and with terms of up to 15 years.

The procedures for underwriting these loans include assessing the applicant’s payment history on other indebtedness, the applicant’s ability to meet existing obligations and payments on the proposed loan, and the loan-to-value ratio. Although the applicant’s creditworthiness is a primary consideration, the underwriting process also includes a comparison of the value of the collateral, if any, to the proposed loan amount.

Consumer Lending. We offer a variety of consumer loans to individuals, including home improvement loans, new and used automobile loans. At June 30, 2022, our consumer loan portfolio totaled $2.2 million, or 1.3% of our total loan portfolio, $2.1 million of which were home improvement loans. Home improvement loans are unsecured fixed-rate loans that must be used to improve a one- to four-family residential real estate or multi-family real estate

8

loan with a maximum amount of $15,000 and a term of five years. Automobile loans are made with a term of five years for vehicles that are two years old or less and up to four years for vehicles that are more than two years old. These loans will be originated with loan-to-value ratios of up to 90% of the value of the vehicle.

Consumer loans generally entail greater risk than one- to four-family residential mortgage loans, particularly in the case of loans that are unsecured or are secured by assets that tend to depreciate in value. As a result, consumer loan collections are primarily dependent on the borrower’s continuing financial stability and thus are more likely to be adversely affected by job loss, divorce, illness or personal bankruptcy. In these cases, repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment for the outstanding loan, and the remaining value often does not warrant further substantial collection efforts against the borrower.

Originations, Sales, Participations and Purchases of Loans

Most of our loan originations are generated by our loan personnel and from referrals from existing customers, real estate brokers, accountants and other professionals. All loans we originate are underwritten pursuant to our policies and procedures. While we originate both fixed-rate and adjustable-rate loans, our ability to generate each type of loan depends upon relative borrower demand and pricing levels established by competing banks, thrifts, credit unions, and mortgage banking companies. Our volume of loan originations is influenced significantly by market interest rates, and, accordingly, the volume of our loan originations can vary from period to period. We do not sell any of the loans we originate.

From time to time, we may purchase loan participations in which we are not the lead lender. From time to time, we may also purchase whole loans. In both of these situations, we follow our customary loan underwriting and approval policies. At June 30, 2022, the outstanding balances of our loan participations where we are not the lead lender totaled $1.5 million, or 0.8% of our loan portfolio, and consisted of five borrower relationships secured by multi-family and commercial real estate located in Connecticut. All such loans were performing in accordance with their original terms. We did not purchase any whole loans during the years ended June 30, 2022 or June 30, 2021. We also have not participated out portions of loans during the years ended June 30, 2022 or 2021.

Loan Approval Procedures and Authority

Pursuant to federal law, the aggregate amount of loans that Colonial Federal Savings Bank is permitted to make to any one borrower or a group of related borrowers is generally limited to 15% of Colonial Federal Savings Bank’s unimpaired capital and surplus (25% if the amount in excess of 15% is secured by “readily marketable collateral” or 30% for certain residential development loans). At June 30, 2022, based on the 15% limitation, Colonial Federal Savings Bank’s loans-to-one-borrower limit was approximately $9.8 million. On the same date, Colonial Federal Savings Bank had no borrowers with outstanding balances in excess of this amount. At June 30, 2022, our largest loan relationship with one borrower was for $4.9 million and consisted of nine loans secured by multi-family real estate and mixed-use real estate. The loans were performing in accordance with their original terms on that date.

Our lending is subject to written underwriting standards and origination procedures. Decisions on loan applications are made on the basis of detailed information submitted by the prospective borrower, credit histories that we obtain, and property valuations (consistent with our appraisal policy) prepared by outside independent licensed appraisers approved by our board of directors or internal evaluations, where permitted by regulations.

The board of directors has granted loan approval authority to a Loan Committee that is comprised of our President and Chief Executive Officer, Treasurer and Chief Operating Officer, Vice President of Retail Lending, Vice President of Financial Markets and Assistant Vice President of Operations. The Loan Committee can approve individual loans up to prescribed limits, depending on the type of loan as follows:

9

Loans that involve policy exceptions also must be approved by the Loan Committee and ratified by the board of directors.

Delinquencies and Non-Performing Assets

Delinquency Procedures. A late notice is sent to a borrower between the 16th and 18th day after a loan is past due. When the loan is 30 days past due, we mail the borrower a letter reminding the borrower of the delinquency and attempt to contact the borrower personally to determine the reason for the delinquency. If necessary, at 45 days past due, additional contact will be made with the borrower, which usually includes an in-person meeting and the account will be monitored on a regular basis thereafter. A property will be inspected between the 30th and 90th day of delinquency. When the loan reaches the 60th day of delinquency, we will send the borrower a letter informing the borrower of their rights and our intent to proceed with further collection efforts, including foreclosure, if the loan default is not cured within 90 days. At the end of the 90-day cure period, a decision will be made whether to begin foreclosure proceedings. Loans are charged off when we believe that the recovery of principal is improbable. A summary report of all loans 30 days or more past due is provided to the board of directors each month.

Troubled Debt Restructurings. A loan is classified as a troubled debt restructuring if, for economic or legal reasons related to the borrower’s financial difficulties, we grant a concession to the borrower that we would not otherwise consider. This usually includes a modification of loan terms, such as a reduction of the interest rate to below market terms, capitalizing past due interest or extending the maturity date and possibly a partial forgiveness of the principal amount due. Interest income on restructured loans is accrued after the borrower demonstrates the ability to pay under the restructured terms through a sustained period of repayment performance, which is generally six consecutive months. We had no troubled debt restructurings at June 30, 2022 and 2021.

The CARES Act, in addition to providing financial assistance to both businesses and consumers, created 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. generally accepted accounting principles related to troubled debt restructurings for a limited period of time to account for the effects of COVID-19. The Federal banking regulatory agencies have likewise issued guidance encouraging financial institutions to work prudently with borrowers who are, or may be, unable to meet their contractual payment obligations because of the effects of COVID-19. That guidance, with concurrence of the Financial Accounting Standards Board and provisions of the CARES Act, allows modifications made on a good faith basis in response to COVID-19 to borrowers who were generally current with their payments on December 31, 2019, to not be treated as troubled debt restructurings. Modifications may include payment deferrals, fee waivers, extensions of repayment term, or other delays in payment. We worked with our customers affected by COVID-19 and accommodated 26 loan modifications totaling $9.5 million, none of which remained on modified payment status at June 30, 2022.

Delinquent Loans. The following table sets forth our loan delinquencies by type and amount at the dates indicated.

Loans Past Due and Non-performing Assets. Loans are reviewed on a regular basis. Management determines that a loan is impaired or non-performing when it is probable at least a portion of the loan will not be collected in accordance with the original terms due to a deterioration in the financial condition of the borrower or the value of the

10

underlying collateral if the loan is collateral dependent. When a loan is determined to be impaired, the measurement of the loan in the allowance for loan losses is based on present value of expected future cash flows, except that all collateral-dependent loans are measured for impairment based on the fair value of the collateral. Non-accrual loans are loans for which collectability is questionable and, therefore, interest on such loans will no longer be recognized on an accrual basis. All loans that become 90 days or more delinquent are placed on non-accrual status unless the loan is well secured and is in the process of collection. When loans are placed on non-accrual status, unpaid accrued interest is fully reversed, and further income is recognized only to the extent received on a cash basis or cost recovery method.

We generally cease accruing interest on our loans when contractual payments of principal or interest have become 90 days past due or management has serious doubts about further collectability of principal or interest, even though the loan is currently performing. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on non-accrual status, unpaid interest credited to income is reversed. Interest received on non-accrual loans is recognized on a cash basis. Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time and the ultimate collectability of the total contractual principal and interest is no longer in doubt.

We had no non-performing loans at June 30, 2022 or 2021.

Real Estate Owned. When we acquire real estate as a result of foreclosure, the real estate is classified as real estate owned. The real estate owned is recorded at fair value, less estimated costs to sell. Soon after acquisition, we order a new appraisal, or evaluation when acceptable, to determine the current market value of the property. Any excess of the recorded value of the loan satisfied over the market value of the property is charged against the allowance for loan losses, or, if the existing allowance is inadequate, charged to expense, in either case during the applicable period of such determination. After acquisition, all costs incurred in maintaining the property are expensed. Costs relating to the development and improvement of the property, however, are capitalized to the extent of estimated fair value less estimated costs to sell. We had no real estate owned at June 30, 2022 or 2021.

Non-Performing Assets. There were no non-performing assets at June 30, 2022 or 2021. There was no additional interest income that would have been recorded for the year ended June 30, 2022 or the year ended June 30, 2021 had non-accruing loans been current according to their original terms.

Classified Assets. Federal regulations provide for the classification of loans and other assets, such as debt and equity securities considered by the Office of the Comptroller of the Currency to be of lesser quality, as “substandard,” “doubtful” or “loss.” 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 characterized by the “distinct possibility” that the insured institution 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 classified as “loss” are those considered “uncollectible” and of such little value that their continuance as assets without the establishment of a specific loss reserve is not warranted. Assets that do not currently expose the insured institution to sufficient risk to warrant classification in one of the aforementioned categories but possess weaknesses are designated as “special mention” by our management.

When an insured institution classifies problem assets as either substandard or doubtful, it may establish general allowances in an amount deemed prudent by management to cover probable accrued losses in the loan portfolio. General allowances represent loss allowances that have been established to cover probable accrued losses associated with lending activities, but that, unlike specific allowances, have not been allocated to particular problem assets. When an insured institution classifies problem assets as “loss,” it is required either to establish a specific allowance for losses equal to 100% of that portion of the asset so classified or to charge-off such amount. An institution’s determination as to the classification of its assets and the amount of its valuation allowances is subject to review by the regulatory authorities, which may require the establishment of additional general or specific loss allowances.

In accordance with our loan policy, we regularly review the problem loans in our portfolio to determine whether any loans require classification in accordance with applicable regulations. Loans are listed on the “watch list” initially because of emerging financial weaknesses even though the loan is currently performing as agreed, or if the loan possesses weaknesses although currently performing. If a loan deteriorates in asset quality, the classification is changed to “special mention,” “substandard,” “doubtful” or “loss” depending on the circumstances and the evaluation.

11

Generally, loans 90 days or more past due are placed on non-accrual status and classified “substandard.” Management reviews the status of each impaired loan on our watch list on a quarterly basis.

On the basis of this review of our assets, our classified loans and special mention loans at the dates indicated were as follows:

The $2.0 million of special mention assets at June 30, 2021 consisted of one commercial real estate loan to a single borrower. This loan was removed from special mention assets as the borrower has shown improvement in his financial condition.

Allowance for Loan Losses

The allowance for loan losses represents management’s estimate of losses inherent in the loan portfolio as of the statement of financial condition date and is recorded as a reduction to loans. The allowance for loan losses is increased by the provision for loan losses, and decreased by charge-offs, net of recoveries. Loans deemed to be uncollectible are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. All, or part, of the principal balance of a loan receivable is charged off as soon as it is determined that the repayment of all, or part, of the principal balance is highly unlikely. Because all identified losses are immediately charged off, no portion of the allowance for loan losses is restricted to any individual loan or groups of loans, and the entire allowance is available to absorb any and all loan losses.

The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management performs a quarterly evaluation of the adequacy of the allowance. The allowance is based on our past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect a given borrower’s ability to repay, the estimated value of any underlying collateral, the size and 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 revision as more information becomes available.

The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as impaired. For loans that are classified as impaired, an allowance is established when the discounted cash flows or collateral value or observable market price of the impaired loan is lower than the carrying value of that loan. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. We do not separately identify consumer loans for impairment disclosure unless such loans are subject to a troubled debt restructuring agreement. The general component covers pools of loans by loan class not considered impaired. These pools of loans are evaluated for loss exposure based upon historical loss rates for each of these categories of loans, adjusted for qualitative factors. These qualitative risk factors include: (1) levels and trends in delinquent, classified, non-accrual and impaired loans, as well as loan modifications; (2) trends in the nature and volume of the portfolio and terms of loans and the existence and effect of any concentrations of credit and changes in the level of such concentrations; (3) effects of the changes in risk selection and lending policies and procedures, including underwriting standards and collection, charge-off, and recovery practices; (4) experience, ability, and depth of lending department management and other relevant staff; and (5) national, regional, and local economic and business conditions as well as the condition of various market segments, including the value of underlying collateral for collateral dependent loans. Each factor is assigned a value to reflect improving, stable or declining conditions based on management’s best judgment using relevant information available at the time of the evaluation. An unallocated component of the allowance for loan losses is maintained to cover uncertainties that could affect management’s estimate of probable

12

losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio.

We will continue to monitor and modify our allowance for loan losses as conditions dictate. No assurances can be given that the level of allowance for loan losses will cover all of the inherent losses on the loans or that future adjustments to the allowance for loan losses will not be necessary if economic and other conditions differ substantially from the economic and other conditions used by management to determine the current level of the allowance for loan losses.

As an integral part of their examination process, the Office of the Comptroller of the Currency periodically reviews our allowance for loan losses, and as a result of such reviews, we may have to adjust our allowance for loan losses. However, regulatory agencies are not directly involved in the process for establishing the allowance for loan losses as the process is our responsibility and any increase or decrease in the allowance is the responsibility of management.

Allowance for Loan Losses. The following table sets forth activity in our allowance for loan losses for the years indicated.

13

Allocation of Allowance for Loan Losses. The following table sets forth the allowance for loan losses allocated by loan category and the percent of the allowance in each category to the total allocated allowance at the dates indicated. The allowance for loan losses allocated to each category is not necessarily indicative of future losses in any particular category and does not restrict the use of the allowance to absorb losses in other categories.

Although we believe that we use the best information available to establish the allowance for loan losses, future adjustments to the allowance may be necessary if economic conditions differ substantially from the assumptions used in making the evaluation. A large loss could deplete the allowance and require increased provisions to replenish the allowance, which would adversely affect earnings.

Investment Activities

General. The board of directors is responsible for approving and overseeing the investment policy, which is reviewed at least annually by the board. The objectives of our investment policy are: (1) to provide liquidity necessary to meet short- and long-term business needs in accordance with our liquidity policy; (2) maintain a balance of high-quality, diversified investments to minimize risk; (3) provide collateral for pledging requirements; (4) generate a reasonable rate of return within the context of our liquidity and credit risk objectives; and (5) help mitigate interest rate risk. The board has delegated to our President and Chief Executive Officer the primary responsibility for oversight and implementation of daily investment activities. The President and Chief Executive Officer has appointed investment officers to assist in overseeing our investing activities and strategies. The authorized officers are our President and Chief Executive Officer, Treasurer and Chief Operating Officer, and Vice President of Financial Markets. Investment officers may purchase or sell on our behalf up to $2.0 million of individual securities and up to $10.0 million in the aggregate per calendar month. Amounts that exceed those thresholds require the approval of the board of directors. The board of directors reviews the activities of the investment officers at each of its meetings.

Our current investment policy authorizes us to invest in various types of investment grade investment securities and liquid assets, including U.S. Treasury obligations (up to 55% of our total investment portfolio), securities of various government-sponsored enterprises (up to 55% of our total investment portfolio), corporate debt (up to 55% of our total investment portfolio), mortgage-backed securities (up to 75% of our total investment portfolio), collateralized mortgage obligations (up to 45% of our total investment portfolio), asset-backed securities (up to 10% of our total investment portfolio), municipal obligations (up to 55% of our total investment portfolio), mutual funds (up to 10% of our total investment portfolio) and certificates of deposit of federally insured institutions (up to 10% of our total investment portfolio). We do not engage in any investment hedging activities or trading activities, nor do we purchase any high-risk mortgage derivative products, corporate junk bonds, or certain types of structured notes.

14

Generally accepted accounting principles require that, at the time of purchase, we designate a debt security as held to maturity, available for sale, or trading, depending on our ability and intent to hold such security. Debt securities designated as available for sale are reported at fair value, while debt securities designated as held to maturity are reported at amortized cost.

At June 30, 2022, our investment portfolio totaled $145.4 million, which consisted of debt obligations, mortgage-backed securities and collateralized mortgage obligations issued by U.S. government-sponsored enterprises as well as corporate and municipal bonds. At such date, $145.2 million was designated as held to maturity and $.2 million was designated as available for sale. At June 30, 2022, we also owned $191,000 of Federal Home Loan Bank of Boston stock. As a member of Federal Home Loan Bank of Boston, we are required to purchase stock in the Federal Home Loan Bank of Boston, which is carried at cost and classified as a restricted investment.

The following table sets forth the weighted average yield for each range of contractual maturities of the held to maturity securities portfolio at June 30, 2022. Actual maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Weighted average yields in the table below have been calculated based on the amortized cost of the security.

For additional information regarding our investment securities portfolio, see Note 3 to the notes to our consolidated financial statements.

Sources of Funds

General. Deposits have traditionally been our primary source of funds for use in lending and investment activities. We also use borrowings, primarily Federal Home Loan Bank of Boston advances, to supplement cash flow needs, lengthen the maturities of liabilities for interest rate risk purposes and to manage the cost of funds. In addition, we receive funds from scheduled loan payments, loan prepayments, maturities, pre-payments and calls of securities, retained earnings and income on earning assets. While scheduled loan payments and income on earning assets are relatively stable sources of funds, deposit inflows and outflows can vary widely and are influenced by prevailing interest rates, market conditions and levels of competition.

Deposits. Our deposits are generated primarily from residents within our primary market area. We offer a selection of deposit accounts, including non-interest-bearing checking accounts, interest-bearing checking accounts, money market accounts, savings accounts and certificates of deposit. Deposit account terms vary, with the principal differences being the minimum balance required, the amount of time the funds must remain on deposit and the interest rate. At June 30, 2022, our core deposits, which are deposits other than certificates of deposit, were $186.9 million, representing 65.1% of total deposits. As part of our business strategy, we intend to continue our effort to increase our core deposits while allowing higher-cost certificates of deposit to run off upon maturity.

Interest rates, maturity terms, service fees and withdrawal penalties are established on a periodic basis. Deposit rates and terms are based primarily on current operating strategies and market rates, liquidity requirements, rates paid by competitors and growth goals. The variety of deposit accounts that we offer allows us to be competitive in generating deposits and to respond with flexibility to changes in our customers’ demands. Our ability to gather deposits is impacted by the competitive market in which we operate, which includes numerous financial institutions of varying sizes offering a wide range of products. We believe that deposits are a stable source of funds, but our ability to attract and maintain deposits at favorable rates will be affected by market conditions, including competition and prevailing interest rates.

15

The following table sets forth the distribution of total deposits by account type at the dates indicated.

At June 30, 2022 and 2021, the aggregate amount of uninsured deposits (deposits in amounts greater than or equal to $250,000, which is the maximum amount for federal deposit insurance) was $75.4 million and $64.4 million, respectively. In addition, as of June 30, 2022, the aggregate amount of all our uninsured certificates of deposit was $24.6 million. We have no deposits that are uninsured for any reason other than being in excess of the maximum amount for federal deposit insurance. The following table sets forth the maturity of the uninsured certificates of deposit as of June 30, 2022.

Borrowed Funds. We may obtain advances from the Federal Home Loan Bank of Boston upon the security of our capital stock in the Federal Home Loan Bank of Boston and certain of our mortgage loans. Such advances may be made pursuant to several different credit programs, each of which has its own interest rate and range of maturities. We use such advances to provide short-term funding as a supplement to our deposits. To the extent such borrowings have different terms to repricing than our deposits, they can change our interest rate risk profile. At June 30, 2022, we had no advances from the Federal Home Loan Bank of Boston. At June 30, 2022, we had the capacity to borrow $70.7 million in Federal Home Loan Bank of Boston advances.

Additionally, at June 30, 2022 we had a $2.4 million available line of credit with the Federal Home Loan Bank of Boston, none of which was drawn at June 30, 2022.

Human Capital Resources

Employees

As of June 30, 2022, we had 28 full-time employees. None of our employees are represented by a labor union or covered by collective bargaining agreements, and we believe our relationship with our employees is good.

Diversity and Inclusion

We are committed to creating and maintaining a workplace free from discrimination or harassment on the basis of color, race, sex, national origin, ethnicity, religion, age, disability, sexual orientation, gender identification or expression or any other status protected by applicable law. Our management team and employees are expected to exhibit and promote honest, ethical and respectful conduct in the workplace. All of our employees must adhere to a

16

code of conduct that sets standards for appropriate behavior and are required to attend annual training to help prevent, identify, report and stop any type of discrimination and harassment. Recruitment, hiring, development, training, compensation and advancement at our company are based on qualifications, performance, skills and experience without regard to gender, race and ethnicity.

Competitive Pay and Benefits

We strive to provide pay, comprehensive benefits and services that help meet the varying needs of our employees. Our total rewards package includes competitive pay, comprehensive healthcare benefits package for employees, family medical leave and flexible work schedules. We sponsor a 401(k) plan and we match employee contributions up to a certain limit. In addition, nearly all of our employees are stockholders of the Company through participation in our Employee Stock Ownership Plan, which aligns stockholder interests by providing stock ownership on a tax-deferred basis at no cost to the employee.

Employee Development and Training

We focus on attracting, retaining, and cultivating talented individuals. We emphasize employee development and training by providing access to a wide range of online and instructor led development and continual learning programs. Employees are encouraged to attend meetings and conferences and have access to broad resources they need to be successful.

Safety

The safety, health and wellness of our employees is a top priority. In response to COVID-19, we maintain safety protocols including, recommending the wearing of masks and social distancing, increased cleaning procedures and readily available hand sanitizer. These protocols take into consideration guidelines of the Centers for Disease Control and Prevention and other public health authorities.

Supervision and Regulation

General

As a federal savings bank, Colonial Federal Savings Bank is subject to examination, supervision and regulation, primarily by the Office of the Comptroller of the Currency, and, secondarily, by the FDIC as deposit insurer. The federal system of regulation and supervision establishes a comprehensive framework of activities in which Colonial Federal Savings Bank may engage and is intended primarily for the protection of depositors and the FDIC’s Deposit Insurance Fund and not for the protection of security holders. The regulatory structure also gives the regulatory authorities extensive discretion in connection with their supervisory and enforcement activities and examination policies. That includes with respect to the classification of assets and the establishment of loan loss reserves for regulatory purposes. In addition, Colonial Federal Savings Bank is a member of and owns stock in the Federal Home Loan Bank of Boston, which is one of the 11 regional banks in the Federal Home Loan Bank System.

Under this system of regulation, the regulatory authorities have extensive discretion in connection with their supervisory, enforcement, rulemaking and examination activities and policies, including rules or policies that: establish minimum capital levels; restrict the timing and amount of dividend payments; govern the classification of assets; provide oversight for the adequacy of loan loss reserves for regulatory purposes; and establish the timing and amounts of assessments and fees. Moreover, as part of their examination authority, the banking regulators assign numerical ratings to banks and savings institutions relating to capital, asset quality, management, liquidity, earnings, interest rate sensitivity and other factors. These ratings are inherently subjective and the receipt of a less than satisfactory rating in one or more categories may result in enforcement action by the banking regulators against a financial institution. A less than satisfactory rating may also prevent a financial institution from obtaining necessary regulatory approvals to access the capital markets, pay dividends, acquire other financial institutions or establish new branches.

In addition, we must comply with significant anti-money laundering and anti-terrorism laws and regulations, Community Reinvestment Act laws and regulations, and fair lending laws and regulations. Government agencies have the authority to impose monetary penalties and other sanctions on institutions that fail to comply with these laws and regulations, which could significantly affect our business activities, including our ability to acquire other financial institutions or expand our branch network.

17

As a savings and loan holding company, CFSB Bancorp is required to comply with the rules and regulations of the Federal Reserve Board. It is subject to examination and supervision by, and be required to file certain reports with, the Federal Reserve Board. CFSB Bancorp is also subject to the rules and regulations of the SEC under the federal securities laws.

Any change in applicable laws or regulations, whether by the Office of the Comptroller of the Currency, the FDIC, the Federal Reserve Board, the SEC or Congress, could have a material adverse impact on the operations and financial performance of CFSB Bancorp and Colonial Federal Savings Bank.

Set forth below are certain material regulatory requirements that are applicable to CFSB Bancorp and Colonial Federal Savings Bank. This description of statutes and regulations is not intended to be a complete description of such statutes and regulations and their effects on CFSB Bancorp and Colonial Federal Savings Bank. Any change in these laws or regulations, whether by Congress or the applicable regulatory agencies, could have a material adverse impact on CFSB Bancorp, Colonial Federal Savings Bank and their operations.

Federal Banking Regulation

Business Activities. A federal savings bank derives its lending and investment powers from the Home Owners’ Loan Act, as amended, and applicable federal regulations. Under these laws and regulations, Colonial Federal Savings Bank may generally invest in mortgage loans secured by residential and commercial real estate, commercial and industrial and consumer loans, certain types of debt securities and certain other assets, subject to applicable limits. Colonial Federal Savings Bank may also establish, subject to specified investment limits, “operating subsidiaries” that may engage in certain activities not otherwise permissible for Colonial Federal Savings Bank, including real estate investment and securities and insurance brokerage.

The Office of the Comptroller of the Currency issued a final rule in 2019 implementing a section of the Economic Growth, Regulatory Relief and Consumer Protection Act (“EGRRCPA”) that permits an eligible federal savings bank with assets of $20.0 billion or less as of December 31, 2017 to elect to operate with the business powers of a national bank, generally subject to the same limitations and restrictions, without converting to a national bank charter. A federal savings bank that makes the so-called “covered savings association” election must divest any activities or investments that are not permitted for a national bank. Colonial Federal Savings Bank had not made such an election as of June 30, 2022.

Capital Requirements. Federal regulations require federally-insured depository institutions, to meet several minimum capital standards: a common equity Tier 1 capital to risk-based assets ratio of 4.5%, a Tier 1 capital to risk-based assets ratio of 6.0%, a total capital to risk-based assets ratio of 8.0% and a Tier 1 capital to total assets leverage ratio of 4.0%.

In determining the amount of risk-weighted assets for calculating risk-based capital ratios, all assets, including certain off-balance sheet assets (e.g., recourse obligations, direct credit substitutes, residual interests) are multiplied by a risk-weight factor assigned by the regulations based on the risks believed inherent in the type of asset. Higher levels of capital are required for asset categories believed to present greater risk. Common equity Tier 1 capital is generally defined as common stockholders’ equity and retained earnings. Tier 1 capital is generally defined as common equity Tier 1 and additional Tier 1 capital. Additional Tier 1 capital includes certain non-cumulative perpetual preferred stock and related surplus and minority interests in equity accounts of consolidated subsidiaries. Total capital includes Tier 1 capital (common equity Tier 1 capital plus additional Tier 1 capital) and Tier 2 capital. Tier 2 capital is comprised of capital instruments and related surplus, meeting specified requirements, and may include cumulative preferred stock and long-term perpetual preferred stock, mandatory convertible securities, intermediate preferred stock and subordinated debt. Also included in Tier 2 capital is the allowance for loan and lease losses limited to a maximum of 1.25% of risk-weighted assets. Calculation of all types of regulatory capital is subject to deductions and adjustments specified in the regulations. In assessing an institution’s capital adequacy, the Office of the Comptroller of the Currency takes into consideration not only these numeric factors, but qualitative factors as well, and has the authority to establish higher capital requirements for individual institutions where deemed necessary.

In addition to establishing the minimum regulatory capital requirements, the regulations limit capital distributions and certain discretionary bonus payments to management if the institution does not hold a “capital conservation buffer” consisting of 2.5% of common equity Tier 1 capital to risk-weighted assets above the amount necessary to meet its minimum risk-based capital requirements.

18

EGRRCPA required the federal banking agencies, including the Office of the Comptroller of the Currency, to establish a “community bank leverage ratio” of between 8% and 10% for institutions with assets of less than $10 billion. Institutions with a capital level at or exceeding the ratio and otherwise meeting the specified requirements, and electing the alternative framework, are considered to comply with the applicable regulatory capital requirements, including the risk-based requirements. Final rules issued by the agencies established the community bank leverage ratio at 9% Tier 1 capital to total average assets, effective January 1, 2020. A qualifying institution may opt in and out of the community bank leverage ratio framework on its quarterly call report. An institution that temporarily ceases to meet any qualifying criteria is provided with a two-quarter grace period to regain compliance. Failure to meet the qualifying criteria within the grace period or maintain a leverage ratio of 8% or greater requires the institution to comply with the generally applicable regulatory capital requirements.

The CARES Act lowered the community bank leverage ratio to 8%, with a federal regulation making the reduced ratio effective April 23, 2020. Another regulation was issued to transition back to the 9% community bank leverage ratio by increasing the ratio to 8.5% for calendar year 2021 and to 9% thereafter. The Company did not opt into the community bank leverage ratio framework.

At June 30, 2022, Colonial Federal Savings Bank’s capital exceeded all applicable requirements.

Loans-to-One Borrower. Generally, a federal savings bank may not make a loan or extend credit to a single or related group of borrowers in excess of 15% of unimpaired capital and surplus. An additional amount may be loaned, equal to 10% of unimpaired capital and surplus, if secured by readily marketable collateral, which generally includes certain financial instruments (but not real estate). As of June 30, 2022, Colonial Federal Savings Bank was in compliance with the loans-to-one borrower limitations.

Standards for Safety and Soundness. Federal law requires each federal banking agency to prescribe certain standards for all insured depository institutions. These standards relate to, among other things, internal controls, information systems and audit systems, loan documentation, credit underwriting, interest rate risk exposure, asset growth, compensation and other operational and managerial standards as the agency deems appropriate. Interagency guidelines set forth the safety and soundness standards that the federal banking agencies use to identify and address problems at insured depository institutions before capital becomes impaired. If the appropriate federal banking agency determines that an institution fails to meet any standard prescribed by the guidelines, the agency may require the institution to submit to the agency an acceptable plan to achieve compliance with the standard. Failure to implement such a plan can result in further enforcement action, including the issuance of a cease and desist order or the imposition of civil money penalties.

Prompt Corrective Action. Federal law requires, among other things, that federal bank regulators take “prompt corrective action” with respect to institutions that do not meet minimum capital requirements. For this purpose, the law establishes five capital categories: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. Under applicable regulations, an institution is deemed to be “well capitalized” if it has a total risk-based capital ratio of 10.0% or greater, a Tier 1 risk-based capital ratio of 8.0% or greater, a leverage ratio of 5.0% or greater and a common equity Tier 1 ratio of 6.5% or greater. An institution is “adequately capitalized” if it has a total risk-based capital ratio of 8.0% or greater, a Tier 1 risk-based capital ratio of 6.0% or greater, a leverage ratio of 4.0% or greater and a common equity Tier 1 ratio of 4.5% or greater. An institution is “undercapitalized” if it has a total risk-based capital ratio of less than 8.0%, a Tier 1 risk-based capital ratio of less than 6.0%, a leverage ratio of less than 4.0% and a common equity Tier 1 ratio of less than 4.5%. An institution is deemed to be “significantly undercapitalized” if it has a total risk-based capital ratio of less than 6.0%, a Tier 1 risk-based capital ratio of less than 4.0%, a leverage ratio of less than 3.0% and a common equity Tier 1 ratio of less than 3.0%. An institution is considered to be “critically undercapitalized” if it has a ratio of tangible equity (as defined in the regulations) to total assets that is equal to or less than 2.0%.

At each successive lower capital category, an insured depository institution is subject to more restrictions and prohibitions, including restrictions on growth, restrictions on interest rates paid on deposits, restrictions or prohibitions on the payment of dividends, and restrictions on the acceptance of brokered deposits. Furthermore, if an insured depository institution is classified in one of the undercapitalized categories, it is required to submit a capital restoration plan to the appropriate federal banking agency, and the holding company must guarantee the performance of that plan. Based upon its capital levels, a bank that is classified as well-capitalized, adequately capitalized, or undercapitalized may be treated as though it were in the next lower capital category if the appropriate federal banking agency, after

19

notice and opportunity for hearing, determines that an unsafe or unsound condition, or an unsafe or unsound practice, warrants such treatment. An undercapitalized bank’s compliance with a capital restoration plan is required to be guaranteed by any company that controls the undercapitalized institution in an amount equal to the lesser of 5.0% of the institution’s total assets when deemed undercapitalized or the amount necessary to achieve the status of adequately capitalized. If an “undercapitalized” bank fails to submit an acceptable plan, it is treated as if it is “significantly undercapitalized.” “Significantly undercapitalized” banks must comply with one or more additional restrictions, including a regulatory order to sell sufficient voting stock to become adequately capitalized, requirements to reduce total assets, ceasing receipt of deposits from correspondent banks, dismissal of directors or officers, and restrictions on interest rates paid on deposits, compensation of executive officers and capital distributions by the parent holding company. “Critically undercapitalized” institutions are subject to additional measures including, subject to a narrow exception, the appointment of a receiver or conservator within 270 days after it obtains such status.

The previously referenced final rule establishing an elective “community bank leverage ratio” regulatory capital framework provides that a qualifying institution whose capital exceeds the community bank leverage ratio and opts to use that framework will be considered “well-capitalized” for purposes of prompt corrective action.

At June 30, 2022, Colonial Federal Savings Bank met the criteria for being considered “well capitalized.”

Capital Distributions. Federal regulations govern capital distributions by a federal savings bank, which include cash dividends and other transactions charged to the savings bank’s capital account. A federal savings bank must file an application with the Office of the Comptroller of the Currency for approval of a capital distribution if:

Even if an application is not otherwise required, every savings bank that is a subsidiary of a savings and loan holding company must file a notice with the Federal Reserve Board at least 30 days before the board of directors declares a dividend or approves a capital distribution. If a savings bank subsidiary of a savings and loan holding company is filing a notice with the Federal Reserve Board for a dividend, and an application to the Office of the Comptroller of the Currency is not otherwise required, then the savings bank must provide to the Office of the Comptroller of the Currency an informational copy of the notice filed with the Federal Reserve Board, at the same time the notice is filed.

An application or notice related to a capital distribution may be disapproved by the agency if:

In addition, the Federal Deposit Insurance Act generally provides that an insured depository institution may not make any capital distribution if, after making such distribution, the institution would fail to meet any applicable regulatory capital requirement.

20

Community Reinvestment Act and Fair Lending Laws. All federal savings banks have a responsibility under the Community Reinvestment Act and related regulations to help meet the credit needs of their communities, including low- and moderate-income borrowers. The Office of the Comptroller of the Currency is required to assess the federal savings bank’s record of compliance with the Community Reinvestment Act. A savings bank’s failure to comply with the provisions of the Community Reinvestment Act could, at a minimum, result in denial of certain corporate applications such as branches or mergers, or in restrictions on its activities. In addition, the Equal Credit Opportunity Act and the Fair Housing Act prohibit lenders from discriminating in their lending practices. The failure to comply with the Equal Credit Opportunity Act and the Fair Housing Act could result in enforcement actions by the Office of the Comptroller of the Currency, as well as other federal regulatory agencies and the Department of Justice.

In June 2020, the Office of the Comptroller of the Currency issued a final rule clarifying and expanding the activities that qualify for Community Reinvestment Act credit and, according to the agency, seeking to create a more consistent and objective method for evaluating Community Reinvestment Act performance. The final rule was effective October 1, 2020, but compliance with certain of the revised requirements is not mandatory for institutions of Colonial Federal Savings Bank’s asset size until January 1, 2024.

The Community Reinvestment Act requires all institutions insured by the FDIC to publicly disclose their rating. Colonial Federal Savings Bank received a “Satisfactory” Community Reinvestment Act rating in its most recent federal evaluation.

Transactions with Related Parties. A federal savings bank’s authority to engage in transactions with its affiliates is limited by Sections 23A and 23B of the Federal Reserve Act and federal regulation. An affiliate is generally a company that controls, or is under common control with, an insured depository institution such as Colonial Federal Savings Bank. CFSB Bancorp is an affiliate of Colonial Federal Savings Bank because of its control of Colonial Federal Savings Bank. In general, transactions between an insured depository institution and its affiliates are subject to certain quantitative limits and collateral requirements. In addition, federal regulations prohibit a savings bank from lending to any of its affiliates that are engaged in activities that are not permissible for bank holding companies and from purchasing the securities of any affiliate, other than a subsidiary. Finally, transactions with affiliates must be consistent with safe and sound banking practices, not involve the purchase of low-quality assets from an affiliate and be on terms that are as favorable to the institution as comparable transactions with non-affiliates.

Colonial Federal Savings Bank’s authority to extend credit to its directors, executive officers and 10% stockholders, as well as to entities controlled by such persons, is currently governed by the requirements of Sections 22(g) and 22(h) of the Federal Reserve Act and Regulation O of the Federal Reserve Board. Among other things, these provisions generally require that extensions of credit to insiders:

In addition, extensions of credit in excess of certain limits must be approved by Colonial Federal Savings Bank’s board of directors. Extensions of credit to executive officers are subject to additional limits based on the type of extension involved.

Enforcement. The Office of the Comptroller of the Currency has primary enforcement responsibility over federal savings banks and has authority to bring enforcement action against all “institution-affiliated parties,” including directors, officers, stockholders, attorneys, appraisers and accountants who knowingly or recklessly participate in wrongful action likely to have an adverse effect on a federal savings bank. Formal enforcement action by the Office of the Comptroller of the Currency may range from the issuance of a capital directive or cease and desist order to removal of officers and/or directors of the institution to the appointment of a receiver or conservator. Civil penalties cover a wide range of violations and actions, and currently range up to $10,000 per day, unless a finding of reckless disregard is made, in which case penalties may be as high as $51,800 per day. Knowing violations may be punished by penalties of up to $2.0 million per day if an institution suffers substantial loss or the violator receives substantial pecuniary gain. The FDIC also has the authority to terminate deposit insurance or recommend to the Office

21

of the Comptroller of the Currency that enforcement action be taken with respect to a particular savings bank. If such action is not taken, the FDIC has authority to take the action under specified circumstances.

Branching. A federal savings bank that has not elected “covered savings association” status generally has authority to establish branches in any state or states of the United States and its territories. Such authority is subject to Office of the Comptroller of the Currency approval for new branches.

Insurance of Deposit Accounts. The Deposit Insurance Fund of the FDIC insures deposits at FDIC-insured financial institutions such as Colonial Federal Savings Bank generally up to a maximum of $250,000 per separately insured depositor. The FDIC charges insured depository institutions premiums to maintain the Deposit Insurance Fund.

Under the FDIC’s risk-based assessment system, institutions deemed less risky pay lower FDIC assessments. Assessments for institutions of less than $10 billion of assets are based on financial measures and supervisory ratings derived from statistical modeling estimating the probability of an institution’s failure within three years.

The FDIC has authority to increase insurance assessments. Any significant increases would have an adverse effect on the operating expenses and results of operations of Colonial Federal Savings Bank. Colonial Federal Savings Bank cannot predict what assessment rates will be in the future.

Insurance of deposits may be terminated by the FDIC upon a finding that an institution has engaged in unsafe or unsound practices, is in an unsafe or unsound condition to continue operations or has violated any applicable law, regulation, rule, order or condition imposed by the FDIC. We do not currently know of any practice, condition or violation that may lead to termination of our deposit insurance.

Privacy Regulations. Federal regulations generally require that Colonial Federal Savings Bank disclose its privacy policy, including identifying with whom it shares a customer’s “non-public personal information,” to customers at the time of establishing the customer relationship and annually thereafter. In addition, Colonial Federal Savings Bank is required to provide its customers with the ability to “opt-out” of having their personal information shared with unaffiliated third parties and not to disclose account numbers or access codes to non-affiliated third parties for marketing purposes. Colonial Federal Savings Bank currently has a privacy protection policy in place and believes that such policy complies with the regulations.

USA PATRIOT Act. Colonial Federal Savings Bank is subject to the USA PATRIOT Act, which gives federal agencies additional powers to address terrorist threats through enhanced domestic security measures, expanded surveillance powers, increased information sharing, and broadened anti-money laundering requirements. The USA PATRIOT Act contains provisions intended to encourage information sharing among bank regulatory agencies and law enforcement bodies and imposes affirmative obligations on financial institutions, such as enhanced recordkeeping and customer identification requirements.

Prohibitions Against Tying Arrangements. Federal savings banks are prohibited, subject to certain exceptions, from extending credit to or offering any other service, or fixing or varying the consideration for such extension of credit or service, on the condition that the customer obtain some additional service from the institution or its affiliates or not obtain services of a competitor of the institution.

Other Regulations

Interest and other charges collected or contracted for by Colonial Federal Savings Bank are subject to state usury laws and federal laws concerning interest rates. Loan operations are also subject to state and federal laws applicable to credit transactions, such as the:

The deposit operations of Colonial Federal Savings Bank also are subject to the:

Colonial Federal Savings Bank is a member of the Federal Home Loan Bank System, which consists of 11 regional Federal Home Loan Banks. The Federal Home Loan Bank provides a central credit facility primarily for member institutions. Members of the Federal Home Loan Bank are required to acquire and hold shares of capital stock in the Federal Home Loan Bank. Colonial Federal Savings Bank was in compliance with this requirement at June 30, 2022. Based on redemption provisions of the Federal Home Loan Bank of Boston, the stock has no quoted market value and is carried at cost. Colonial Federal Savings Bank reviews for impairment, based on the ultimate recoverability, the cost basis of the Federal Home Loan Bank of Boston stock. At June 30, 2022, no impairment had been recognized.

Holding Company Regulation

General. CFSB Bancorp and 15 Beach, MHC are savings and loan holding companies within the meaning of the Home Owners’ Loan Act. As such, CFSB Bancorp and 15 Beach, MHC are registered with the Federal Reserve Board and subject to the regulation, examination, supervision and reporting requirements applicable to savings and loan holding companies. In addition, the Federal Reserve Board has enforcement authority over CFSB Bancorp, 15 Beach, MHC and its non-savings institution subsidiaries. Among other things, this authority permits the Federal Reserve Board to restrict or prohibit activities that are determined to be a serious risk to Colonial Federal Savings Bank.

Permissible Activities. Under present law, the business activities of CFSB Bancorp and 15 Beach, MHC are generally limited to those activities permissible for financial holding companies under Section 4(k) of the Bank Holding Company Act of 1956, as amended, provided certain conditions are met and financial holding company status is elected, and for multiple savings and loan holding companies. A financial holding company may engage in activities that are financial in nature, including underwriting equity securities and insurance as well as activities that are incidental to financial activities or complementary to a financial activity. A multiple savings and loan holding company is generally limited to activities permissible for bank holding companies under Section 4(c)(8) of the Bank Holding Company Act, subject to regulatory approval, and certain additional activities authorized by federal regulations. CFSB Bancorp and 15 Beach, MHC have not elected financial holding company status.

23

Federal law prohibits a savings and loan holding company, including CFSB Bancorp and 15 Beach, MHC, directly or indirectly, or through one or more subsidiaries, from acquiring more than 5% of another savings association or savings and loan holding company, without prior Federal Reserve Board approval. In evaluating applications by holding companies to acquire savings institutions, the Federal Reserve Board considers factors such as the financial and managerial resources, future prospects of the company and institution involved, the effect of the acquisition on and the risk to the federal deposit insurance fund, the convenience and needs of the community and competitive factors.

The Federal Reserve Board is prohibited from approving any acquisition that would result in a multiple savings and loan holding company controlling savings institutions in more than one state, subject to two exceptions:

Capital. Savings and loan holding companies with less than $3.0 billion in consolidated assets are generally not subject to the regulatory capital requirements unless otherwise advised by the Federal Reserve Board.

Source of Strength. The Dodd-Frank Act extended the “source of strength” doctrine to savings and loan holding companies. The Federal Reserve Board has issued regulations requiring that all savings and loan holding companies serve as a source of financial and managerial strength to their subsidiary depository institutions.

Dividends and Stock Repurchases. The Federal Reserve Board has issued a policy statement regarding the payment of dividends and the repurchase of shares of common stock by holding companies. In general, the policy provides that dividends should be paid only out of current earnings and only if the prospective rate of earnings retention by the holding company appears consistent with the organization’s capital needs, asset quality and overall supervisory financial condition. Federal Reserve Board regulatory guidance provides for prior consultation with Federal Reserve Bank staff concerning dividends in certain circumstances such as where the company’s net income for the past four quarters, net of capital distributions previously paid over that period, is insufficient to fully fund the dividend or the company’s overall rate or earnings retention is inconsistent with the company’s capital needs and overall financial condition. The ability of a holding company to pay dividends may be restricted if a subsidiary bank becomes undercapitalized. Federal Reserve Board guidance also states that a holding company should inform Federal Reserve Bank supervisory staff prior to redeeming or repurchasing common stock or perpetual preferred stock if the holding company is experiencing financial weaknesses or the repurchase or redemption would result in a net reduction, at the end of a quarter, in the amount of such equity instruments outstanding compared with the beginning of the quarter in which the redemption or repurchase occurred. These regulatory policies may affect the ability of CFSB Bancorp to pay dividends, repurchase shares of common stock or otherwise engage in capital distributions.

Waivers of Dividends by 15 Beach, MHC. CFSB Bancorp may pay dividends on its common stock to public stockholders. If it does, it is also required to pay dividends to 15 Beach, MHC, unless 15 Beach, MHC elects to waive the receipt of dividends. 15 Beach, MHC must receive the approval of the Federal Reserve Board before it may waive the receipt of any dividends from CFSB Bancorp. The Federal Reserve Board has issued an interim final rule providing that it will not object to dividend waivers under certain circumstances, including circumstances where the waiver is not detrimental to the safe and sound operation of the savings bank and a majority of the mutual holding company’s members have approved the waiver of dividends by the mutual holding company within the previous twelve months. In addition, for a “non-grandfathered” mutual holding company such as 15 Beach, MHC, each officer or director of CFSB Bancorp and Colonial Federal Savings Bank, and any tax-qualified stock benefit plan or non-tax-qualified stock benefit plan in which such individual participates that holds any shares of stock to which the waiver would apply, must waive the right to receive any such dividend declared. In addition, any dividends waived by 15 Beach, MHC must be considered in determining an appropriate exchange ratio in the event of a conversion of the mutual holding company to stock form.

Change in Control Regulations

Under the Change in Bank Control Act, no person may acquire “control” of a savings and loan holding company, such as CFSB Bancorp, unless the Federal Reserve Board has been given 60 days’ prior written notice and

24

has not issued a notice disapproving the proposed acquisition, taking into consideration certain factors, including the financial and managerial resources of the acquirer and the competitive effects of the acquisition. Control, as defined under federal law, means ownership, control of or holding irrevocable proxies representing more than 25% of any class of voting stock, control in any manner of the election of a majority of the institution’s directors, or a determination by the regulator that the acquirer has the power, directly or indirectly, to exercise a controlling influence over the management or policies of the institution. There is a presumption of control upon the acquisition of 10% or more of a class of voting stock under certain circumstances, such as where the holding company involved has its shares registered under the Exchange Act.

Sarbanes-Oxley Act of 2002

The Sarbanes-Oxley Act of 2002 is intended to improve corporate responsibility, to provide for enhanced penalties for accounting and auditing improprieties at publicly traded companies and to protect investors by improving the accuracy and reliability of corporate disclosures pursuant to the securities laws. We have policies, procedures and systems designed to comply with these regulations, and we review and document such policies, procedures and systems to ensure continued compliance with these regulations.

Emerging Growth Company Status

CFSB Bancorp is an emerging growth company. For as long as CFSB Bancorp continues to be an emerging growth company, it may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to “emerging growth companies,” including, but not limited to, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. As an emerging growth company, CFSB Bancorp also is not subject to Section 404(b) of the Sarbanes-Oxley Act of 2002, which would require that its independent auditors review and attest as to the effectiveness of its internal control over financial reporting. CFSB Bancorp has also elected to use the extended transition period to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. Such an election is irrevocable during the period a company is an emerging growth company. Accordingly, its financial statements may not be comparable to the financial statements of public companies that comply with such new or revised accounting standards.

A company loses emerging growth company status on the earlier of: (1) the last day of the fiscal year of the company during which it had total annual gross revenues of $1.0 billion or more; (2) the last day of the fiscal year of the issuer following the fifth anniversary of the date of the first sale of common equity securities of the company pursuant to an effective registration statement under the Securities Act of 1933; (3) the date on which such company has, during the previous three-year period, issued more than $1.0 billion in non-convertible debt; or (4) the date on which such company is deemed to be a “large accelerated filer” under SEC regulations (generally, at least $700 million of voting and non-voting equity held by non-affiliates).

Taxation

15 Beach, MHC, CFSB Bancorp and Colonial Federal Savings Bank are subject to federal and state income taxation in the same general manner as other corporations, with some exceptions discussed below. The following discussion of federal and state taxation is intended only to summarize material income tax matters and is not a comprehensive description of the tax rules applicable to 15 Beach, MHC, CFSB Bancorp and Colonial Federal Savings Bank.

Our federal and state tax returns have not been audited for the past five years.

Federal Taxation

Method of Accounting. For federal income tax purposes, Colonial Federal Savings Bank currently reports its income and expenses on the accrual method of accounting and uses a tax year ending June 30 for filing its federal income tax returns. CFSB Bancorp and Colonial Federal Savings Bank file a consolidated federal income tax return.

25

The Small Business Protection Act of 1996 eliminated the use of the reserve method of accounting for income taxes on bad debt reserves by savings institutions with more than $500 million in assets. For taxable years beginning after 1995, Colonial Federal Savings Bank has been subject to the same bad debt reserve rules as commercial banks. It currently utilizes the experience method under Section 585(b)(2) of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”).

Net Operating Loss Carryovers. Effective with the passage of the Tax Cuts and Jobs Act, net operating loss carrybacks are no longer permitted, and net operating losses are allowed to be carried forward indefinitely. Net operating loss carryforwards arising from tax years beginning after January 1, 2018 are limited to offset a maximum of 80% of a future year’s taxable income.

Capital Loss Carryovers. Generally, a financial institution may carry back capital losses to the preceding three taxable years and forward to the succeeding five taxable years. Any capital loss carryback or carryover is treated as a short-term capital loss for the year to which it is carried. As such, it is grouped with any other capital losses for the year to which carried and is used to offset any capital gains. Any loss remaining after the five-year carryover period that has not been deducted is no longer deductible. At June 30, 2022, Colonial Federal Savings Bank had no capital loss carryovers.

Corporate Dividends. CFSB Bancorp may generally exclude from its income 100% of dividends received from Colonial Federal Savings Bank as a member of the same affiliated group of corporations.

State Taxation

Financial institutions in Massachusetts are required to file combined income tax returns. The current Massachusetts excise tax rate for financial institutions is 9.0% of federal taxable income, adjusted for certain items. Taxable income includes gross income as defined under the Internal Revenue Code, plus interest from bonds, notes and evidences of indebtedness of any state, including Massachusetts, less deductions, but not the credits, allowable under the provisions of the Internal Revenue Code, except for those deductions relating to dividends received and income or franchise taxes imposed by a state or political subdivision. Carryforwards and carrybacks of net operating losses and capital losses are not allowed.

A financial institution or business corporation is generally entitled to special tax treatment as a “security corporation” under Massachusetts law provided that: (1) its activities are limited to buying, selling, dealing in or holding securities on its own behalf and not as a broker; and (2) it has applied for, and received, classification as a “security corporation” by the Commissioner of the Massachusetts Department of Revenue. A security corporation that is also a bank holding company under the Internal Revenue Code must pay a tax equal to 0.33% of its gross income. A security corporation that is not a bank holding company under the Internal Revenue Code must pay a tax equal to 1.32% of its gross income. Beach Street Securities Corporation is qualified as a security corporation that is not a bank holding company. As such, it has received security corporation classification by the Massachusetts Department of Revenue and does not conduct any activities deemed impermissible under the governing statutes and the various regulations, directives, letter rulings and administrative pronouncements issued by the Massachusetts Department of Revenue.

Item 1A. Risk Factors.

Risks Related to the COVID-19 Pandemic

The economic impact of the COVID-19 outbreak could adversely affect our financial condition and results of operations.

Given the ongoing and dynamic nature of the pandemic, we cannot predict the continuing impact of the COVID-19 outbreak on our business and on our prospects. The extent of such impact will depend on future developments, which are highly uncertain, including when the pandemic can be controlled and abated. As the result of the COVID-19 pandemic and the related adverse economic consequences, we could be subject to any of the following risks, any of which could have a material, adverse effect on our business, financial condition, liquidity, prospects and results of operations:

Moreover, our future success and profitability substantially depends on the management skills of our executive officers and directors, some of whom have held officer and director positions with us for many years. The unanticipated loss or unavailability of key employees due to the outbreak could harm our ability to operate our business or execute our business strategy. We may not be successful in finding and integrating suitable successors in the event of key employee loss or unavailability.

Any one or a combination of the factors identified above could negatively impact our business, financial condition and results of operations and prospects.

Risks Related to our Lending Activities

Almost all of our loans are secured by real estate, and a downturn in the local real estate market could negatively impact our profitability.

At June 30, 2022, approximately $172.5 million, or 98.7%, of our total loan portfolio was secured by real estate, most of which is located in our primary lending market area of Norfolk and Plymouth Counties, Massachusetts and surrounding areas. Future declines in the real estate values in our primary lending markets and surrounding markets because of an economic downturn could significantly impair the value of the particular collateral securing our loans and our ability to sell the collateral upon foreclosure for an amount necessary to satisfy the borrower’s obligations to us. This could require increasing our allowance for loan losses to address the decrease in the value of the real estate securing our loans, which could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

Unlike larger financial institutions that are more geographically diversified, our profitability depends primarily on the general economic conditions in our primary market area. Local economic conditions have a significant impact

27

on our residential real estate and other types of lending, including, the ability of borrowers to repay these loans and the value of the collateral securing these loans.

Moreover, a significant decline in general economic conditions, caused by inflation, acts of terrorism, an outbreak of hostilities or other international or domestic calamities or other factors beyond our control could further impact these local economic conditions and could further negatively affect our financial performance. In addition, deflationary pressures, while possibly lowering our operating costs, could have a significant negative effect on our borrowers, especially our business borrowers, and the values of underlying collateral securing loans, which could negatively affect our financial performance.

If our allowance for loan losses is not sufficient to cover actual loan losses, our earnings could decrease.

We make various assumptions and judgments about the collectability of our loan portfolio, including the creditworthiness of our borrowers and the value of the real estate and other assets serving as collateral for the repayment of many of our loans. In determining the amount of the allowance for loan losses, we review our loans and our loss and delinquency experience, and we evaluate economic conditions. If our assumptions or the results of our analyses are incorrect, our allowance for loan losses may not be sufficient to cover losses inherent in our loan portfolio, resulting in additions to our allowance. In addition, our emphasis on loan growth and on increasing our portfolio of multi-family and commercial real estate loans, as well as any future credit deterioration, including as a result of COVID-19, could require us to increase our allowance for loan losses in the future. At June 30, 2022, our allowance for loan losses as a percentage of total loans was 1.00%. Material additions to our allowance would materially decrease our net income.

The Financial Accounting Standards Board has delayed the effective date of the implementation of Current Expected Credit Losses, (“CECL"), standard. CECL will be effective for CFSB Bancorp on July 1, 2023. CECL will require financial institutions to determine periodic estimates of lifetime expected credit losses on loans, and recognize the expected credit losses as allowances for credit losses. This will change the current method of providing allowances for loan losses that are incurred or probable, which would likely require us to increase our allowance for credit losses, and to greatly increase the types of data we would need to collect and review to determine the appropriate level of the allowance for credit losses.

In addition, bank regulators periodically review our allowance for loan losses and, as a result of such reviews, we may be required to increase our provision for loan losses or recognize further loan charge-offs. Any increase in our allowance for loan losses or loan charge-offs as a result of such review or otherwise may have a material adverse effect on our financial condition and results of operations.

We intend to increase the origination of multi-family and commercial real estate loans. These loans involve credit risks that could adversely affect our financial condition and results of operations.

At June 30, 2022, commercial real estate loans totaled $14.8 million, or 8.5% of our loan portfolio and multi-family real estate loans totaled $14.3 million, or 8.2% of our loan portfolio. Given their larger balances and the complexity of the underlying collateral, multi-family and commercial real estate loans generally have more risk than the owner-occupied one- to four-family residential real estate loans that we originate. Because the repayment of multi-family and commercial real estate loans depends on the successful management and operation of the borrower’s properties or related businesses, repayment of such loans can be affected by adverse conditions in the local real estate market or economy. The adverse effects of the COVID-19 pandemic could adversely impact the value of properties securing the loan or the revenues from the borrower’s business, thereby increasing the risk of non-performing loans. If we foreclose on these loans, our holding period for the collateral typically is longer than for a one- to four-family residential property because there are fewer potential purchasers of the collateral. In addition, multi-family and commercial real estate loans typically involve larger loan balances to single borrowers or groups of related borrowers compared to one- to four-family residential loans. Accordingly, charge-offs on multi-family and commercial real estate loans may be larger on a per loan basis than those incurred by our one- to four-family residential real estate or consumer loan portfolios.

As our multi-family and commercial real estate loan portfolio increases, the corresponding risks and potential for losses from these loans may also increase, which would adversely affect our business, financial condition and results of operations.

28

Our non-owner-occupied one- to four-family residential real estate loans may expose us to increased credit risk.

At June 30, 2022, $18.8 million, or 10.8%, of our total loan portfolio consisted of loans secured by non-owner-occupied one- to four-family residential real estate properties. At June 30, 2022, all of our non-owner-occupied one- to four-family residential real estate loans were performing in accordance with their repayment terms. One- to four-family residential loans secured by non-owner-occupied properties generally expose a lender to greater risk of non-payment and loss than loans secured by owner-occupied properties because repayment of such loans depend primarily on the tenant’s continuing ability to pay rent to the property owner, who is our borrower, or, if the property owner is unable to find a tenant, the property owner’s ability to repay the loan without the benefit of a rental income stream. In addition, the physical condition of non-owner-occupied properties may be below that of owner-occupied properties due to lenient property maintenance standards that negatively impact the value of the collateral properties.

Risks Related to our Business Strategy

Our business strategy includes loan growth, and our financial condition and results of operations could be negatively affected if we fail to grow or fail to manage our growth effectively. Growing our operations could also cause our expenses to increase faster than our revenues.

Our business strategy primarily focuses on loan growth, funded by deposits. Achieving such growth may require us to attract customers that currently bank at other financial institutions in our market area. Our ability to successfully grow will depend on a variety of factors, including our ability to attract and retain experienced bankers, the continued availability of desirable business opportunities, the level of competition from other financial institutions in our market area and our ability to manage our growth. Growth opportunities may not be available or we may not be able to manage our growth successfully. If we do not manage our growth effectively, our financial condition and operating results could be negatively affected. Furthermore, there can be considerable costs involved in opening branches and expanding lending capacity, and generally a period of time is required to generate the necessary revenues to offset these costs, especially in areas in which we do not have an established presence. Accordingly, any such business expansion can be expected to negatively impact our earnings until certain economies of scale are reached. Our expenses could be further increased if we encounter delays in the opening of new branches.

A significant percentage of our assets is invested in securities, which typically have a lower yield than our loan portfolio.

Our results of operations depend substantially on our net interest income. At June 30, 2022, 48.4% of our assets were invested in investment securities and cash and cash equivalents. These investments yield substantially less than the loans we hold in our portfolio. While we intend to invest a greater proportion of our assets in loans with the goal of increasing our net interest income, we may not be able to increase originations of loans that are acceptable to us. Further, at June 30, 2022, $145.2 million, or 99.9%, of our securities portfolio was designated as held to maturity. As a result, we are unable to sell these securities to respond to changes in interest rates that may occur in the future.

We depend on our management team and other key personnel to implement our business strategy and execute successful operations and we could be harmed by the loss of their services or the inability to hire additional personnel.

We depend on the services of the members of our senior management team who direct our strategy and operations. Our executive officers and lending personnel possess substantial expertise, extensive knowledge of our markets and key business relationships. Any one of them could be difficult to replace. Our loss of these persons, or our inability to hire additional qualified personnel, could impact our ability to implement our business strategy and could have a material adverse effect on our results of operations and our ability to compete in our markets.

Risks Related to Market Interest Rates

Future changes in interest rates could negatively affect our operating results and asset values.

Net income is the amount by which net interest income and non-interest income exceed non-interest expense and the provision for loan losses. Net interest income makes up a majority of our income and is based on the difference between:

29

The rates we earn on our assets and the rates we pay on our liabilities are generally fixed for a contractual period of time. Like many savings institutions, our liabilities generally have shorter contractual maturities than our assets. This is exacerbated due to our historical focus on one- to four-family residential real estate loans, the substantial majority of which have fixed interest rates. This imbalance can create significant earnings volatility because market interest rates change over time. In a period of rising interest rates, the interest income we earn on our assets may not increase as rapidly as the interest we pay on our liabilities. Furthermore, increases in interest rates may adversely affect our ability to originate loans and/or the ability of our borrowers to make loan repayments on adjustable-rate loans, as the interest owed on such loans would increase as interest rates increase. In a period of declining interest rates, the interest income we earn on our assets may decrease more rapidly than the interest we pay on our liabilities, as borrowers prepay mortgage loans, and mortgage-backed securities and callable securities are called, requiring us to reinvest those cash flows at lower interest rates.

In addition, changes in interest rates can affect the average life of loans and mortgage-backed and related securities. A decline in interest rates generally results in increased prepayments of loans and mortgage-backed and related securities as borrowers refinance their debt to reduce their borrowing costs. This creates reinvestment risk, which is the risk that we may not be able to reinvest prepayments at rates that are comparable to the rates we earned on the prepaid loans or securities. Furthermore, an inverted interest rate yield curve, where short-term interest rates (which are usually the rates at which financial institutions borrow funds) are higher than long-term interest rates (which are usually the rates at which financial institutions lend funds for fixed-rate loans) can reduce a financial institution’s net interest margin and create financial risk for financial institutions that originate longer-term, fixed-rate mortgage loans.

Any substantial, unexpected, prolonged change in market interest rates could have a material adverse effect on our financial condition, liquidity, and results of operations. Changes in the level of interest rates also may negatively affect the value of our assets and ultimately affect our earnings.

We monitor interest rate risk through the use of simulation models, including estimates of the amounts by which the fair value of our assets and liabilities (our economic value of equity or “EVE”) and our net interest income would change in the event of a range of assumed changes in market interest rates. As of June 30, 2022, in the event of an instantaneous 100 basis point increase in interest rates, we estimate that we would experience an 8.6% decrease in EVE and a 2.1% decrease in net interest income. For further discussion of how changes in interest rates could impact us, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations of Colonial Federal Savings Bank—Management of Market Risk.”

Risks Related to Competitive Matters

Strong competition within our market areas may limit our growth and profitability.

Competition in the banking and financial services industry is intense. In our market area, we compete with commercial banks, savings institutions, mortgage brokerage firms, credit unions, finance companies, mutual funds, insurance companies, and securities brokerage firms and unregulated or less regulated non-banking entities, operating locally and elsewhere. Many of these competitors have substantially greater resources and higher lending limits than we have and offer certain services that we do not or cannot provide. If we must raise interest rates paid on deposits or lower interest rates charged on our loans, our net interest margin and profitability could be adversely affected. In addition, some of our competitors offer loans with lower interest rates on more attractive terms than loans we offer. Competition also makes it increasingly difficult and costly to attract and retain qualified employees. Our profitability depends upon our continued ability to successfully compete in our market area.

The financial services industry could become even more competitive as a result of new legislative, regulatory and technological changes and continued consolidation. Banks, securities firms and insurance companies can merge under the umbrella of a financial holding company, which can offer virtually any type of financial service, including banking, securities underwriting, insurance (both agency and underwriting) and merchant banking. Also, technology has lowered barriers to entry and made it possible for non-banks, such as financial technology companies, securities companies and specialty finance companies to offer products and services traditionally provided by banks, such as

30

automatic transfer and automatic payment systems. Many of our competitors have fewer regulatory constraints and may have lower cost structures. Additionally, due to their size, many competitors may be able to achieve economies of scale and, as a result, may offer a broader range of products and services as well as better pricing for those products and services than we can. We expect competition to increase in the future because of legislative, regulatory and technological changes and the continuing trend of consolidation in the financial services industry. For additional information see “Business of Colonial Federal Savings Bank—Market Area” and “—Competition.”

Our asset size may make it more difficult for us to compete.

Our asset size may make it more difficult to compete with other financial institutions that are larger and can more easily afford to invest in the marketing and technologies needed to attract and retain customers. Because our principal source of income is the net interest income we earn on our loans and investments after deducting interest paid on deposits and other sources of funds, our ability to generate the revenues needed to cover our expenses and finance such investments is limited by the size of our loan and investment portfolios. Accordingly, we are not always able to offer new products and services as quickly as our competitors. Our lower earnings may also make it more difficult to offer competitive salaries and benefits. In addition, our smaller customer base may make it difficult to generate meaningful non-interest income from non-traditional banking activities. Finally, as a smaller institution, we are disproportionately affected by the continually increasing costs of compliance with new banking and other regulations.

Risks Related to Laws and Regulations

Changes in laws and regulations and the cost of regulatory compliance with new laws and regulations may adversely affect our operations and/or increase our costs of operations.

Colonial Federal Savings Bank is subject to extensive regulation, supervision and examination by the Office of the Comptroller of the Currency, and CFSB Bancorp is subject to extensive regulation, supervision and examination by the Federal Reserve Board. Such regulation and supervision governs the activities in which an institution and its holding company may engage and are intended primarily for the protection of the federal deposit insurance fund and the depositors and borrowers of Colonial Federal Savings Bank, rather than for our stockholders.

Regulatory authorities have extensive discretion in their supervisory and enforcement activities, including the imposition of restrictions on our operations, the classification of our assets and determination of the level of our allowance for loan losses. These regulations, along with existing tax, accounting, securities, insurance and monetary laws, rules, standards, policies, and interpretations, control the methods by which financial institutions conduct business, implement strategic initiatives and tax compliance, and govern financial reporting and disclosures. Any change in such regulation and oversight, whether in the form of regulatory policy, regulations, legislation or supervisory action, may have a material impact on our operations. Further, changes in accounting standards can be both difficult to predict and involve judgment and discretion in their interpretation by us and our independent accounting firm. These changes could materially impact, potentially even retroactively, how we report our financial condition and results of operations.

Non-compliance with the USA PATRIOT Act, Bank Secrecy Act, or other laws and regulations could result in fines or sanctions.

The USA PATRIOT and Bank Secrecy Acts require financial institutions to develop programs to prevent financial institutions from being used for money laundering and terrorist activities. If such activities are detected, financial institutions are obligated to file suspicious activity reports with the U.S. Treasury’s Office of Financial Crimes Enforcement Network. These rules require financial institutions to establish procedures for identifying and verifying the identity of customers seeking to open new financial accounts. Failure to comply with these regulations could result in fines or sanctions, including restrictions on pursuing acquisitions or establishing new branches. The policies and procedures we have adopted that are designed to assist in compliance with these laws and regulations may not be effective in preventing violations of these laws and regulations.

31

The Federal Reserve Board may require us to commit capital resources to support Colonial Federal Savings Bank, and we may not have sufficient access to such capital resources.

Federal law requires that a holding company act as a source of financial and managerial strength to its subsidiary bank and to commit resources to support such subsidiary bank. Under the “source of strength” doctrine, the Federal Reserve Board may require a holding company to make capital injections into a troubled subsidiary bank and may charge the holding company with engaging in unsafe and unsound practices for failure to commit resources to a subsidiary bank. A capital injection may be required at times when the holding company may not have the resources to provide it and therefore may be required to attempt to borrow the funds or raise capital. Any loans by a holding company to its subsidiary bank are subordinate in right of payment to deposits and to certain other indebtedness of such subsidiary bank. In the event of a holding company’s bankruptcy, the bankruptcy trustee will assume any commitment by the holding company to a federal bank regulatory agency to maintain the capital of a subsidiary bank. Moreover, bankruptcy law provides that claims based on any such commitment will be entitled to a priority of payment over the claims of the institution’s general unsecured creditors, including the holders of its note obligations. Thus, any borrowing that must be done by CFSB Bancorp to make a required capital injection becomes more difficult and expensive and could have an adverse effect on our business, financial condition and results of operations. Moreover, it is possible that we will be unable to borrow funds when we need to do so.

Monetary policies and regulations of the Federal Reserve Board could adversely affect our business, financial condition and results of operations.

In addition to being affected by general economic conditions, our earnings and growth are affected by the policies of the Federal Reserve Board. An important function of the Federal Reserve Board is to regulate the money supply and credit conditions. Among the instruments used by the Federal Reserve Board to implement these objectives are open market purchases and sales of U.S. government securities, adjustments of the discount rate and changes in banks’ reserve requirements against bank deposits. These instruments are used in varying combinations to influence overall economic growth and the distribution of credit, bank loans, investments and deposits. Their use also affects interest rates charged on loans or paid on deposits.

The monetary policies and regulations of the Federal Reserve Board have had a significant effect on the operating results of financial institutions in the past and are expected to continue to do so in the future. The effects of such policies upon our business, financial condition and results of operations cannot be predicted.

We are an emerging growth company, and any decision on our part to comply only with certain reduced reporting and disclosure requirements applicable to emerging growth companies could make our common stock less attractive to investors.

We are an emerging growth company, and, for as long as we continue to be an emerging growth company, we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to “emerging growth companies,” including, but not limited to, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. As an emerging growth company, we also will not be subject to Section 404(b) of the Sarbanes-Oxley Act, which would require that our independent auditors review and attest as to the effectiveness of our internal control over financial reporting. We have also elected to use the extended transition period to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. Accordingly, our financial statements may not be comparable to the financial statements of public companies that comply with such new or revised accounting standards.

We can remain an “emerging growth company” for up to five years, or until the earliest of (1) the last day of the first fiscal year in which our annual gross revenues exceed $1.07 billion, (2) the date that we become a “large accelerated filer” as defined in Rule 12b-2 under the Exchange Act, which would occur if the market value of our common stock that is held by non-affiliates exceeds $700 million as of the last business day of our most recently completed second fiscal quarter, or (3) the date on which we have issued more than $1.0 billion in non-convertible debt during the preceding three-year period.

As a result, our stockholders may not have access to certain information they may deem important, and investors may find our common stock less attractive if we choose to rely on these exemptions. This could result in a less active trading market for our common stock and the price of our common stock may be more volatile.

32

We qualify as a smaller reporting company, and any decision on our part to comply only with certain reduced reporting and disclosure requirements applicable to smaller reporting companies could make our common stock less attractive to investors.

We are a smaller reporting company, and, for as long as we continue to qualify as a smaller reporting company, we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to smaller reporting companies, including, but not limited to, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and two years of audited financial statements in our annual report instead of three years. As long as we are not an accelerated filer, we will not be subject to Section 404(b) of the Sarbanes-Oxley Act, which requires that our independent registered public accountants review and attest as to the effectiveness of our internal control over financial reporting. In addition, as a non-accelerated filer, we will have longer deadlines to file our periodic reports with the Securities and Exchange Commission.

We would remain a smaller reporting company and a non-accelerated filer for so long as our voting and non-voting equity held by non-affiliates (“public float”) is less than $250 million or our annual revenues are less than $100 million and our public float is less than $700 million. Public float is determined each year as of the end of a company’s second fiscal quarter applicable at the end of the fiscal year involved.

As a result of our smaller reporting company and non-accelerated filer status, our stockholders may not have access to certain information they may deem important, and investors may find our common stock less attractive if we choose to rely on these exemptions. This could result in a less active trading market for our common stock and the price of our common stock may be more volatile.

Risks Related to Operational Matters

We face significant operational risks because of our reliance on technology. Our information technology systems may be subject to failure, interruption or security breaches.

Information technology systems are critical to our business. Our business requires us to collect, process, transmit and store significant amounts of confidential information regarding our customers, employees and our own business, operations, plans and business strategies. We use various technology systems to manage our customer relationships, general ledger, securities investments, deposits, and loans. Our computer systems, data management and internal processes, as well as those of third parties, are integral to our performance. Our operational risks include the risk of malfeasance by employees or persons outside our company, errors relating to transaction processing and technology, systems failures or interruptions, breaches of our internal control systems and compliance requirements, and business continuation and disaster recovery. There have been increasing efforts by third parties to breach data security at financial institutions. Such attacks include computer viruses, malicious or destructive code, phishing attacks, denial of service or information or other security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss or destruction of confidential, proprietary and other information, damages to systems, or other material disruptions to network access or business operations. Although we take protective measures and believe that we have not experienced any of the data breaches described above, the security of our computer systems, software, and networks may be vulnerable to breaches, unauthorized access, misuse, computer viruses, or other malicious code and cyber-attacks that could have an impact on information security. Because the techniques used to cause security breaches change frequently, we may be unable to proactively address these techniques or to implement adequate preventative measures.

In the event of a breakdown in our internal control systems, improper operation of systems or improper employee actions, or a breach of our security systems, including if confidential or proprietary information were to be mishandled, misused or lost, we could suffer financial loss, loss of customers and damage to our reputation, and face regulatory action or civil litigation. Any of these events could have a material adverse effect on our financial condition and results of operations. Insurance coverage may not be available for such losses, or where available, such losses may exceed insurance limits.

We rely on third-party vendors, which could expose us to additional cybersecurity risks.

Third-party vendors provide key components of our business infrastructure, including certain data processing and information services. Accordingly, our operations are exposed to risk that these vendors will not perform in accordance with our contractual agreements with them, or we also could be adversely affected if such an agreement is not renewed by the third-party vendor or is renewed on terms less favorable to us. If our third-party providers

33

encounter difficulties, or if we have difficulty communicating with those service providers, our ability to adequately process and account for transactions could be affected, and our business operations could be adversely affected, which could have a material adverse effect on our financial condition and results of operations. Threats to information security also exist in the processing of customer information through various other vendors and their personnel.

We may be subject to risks and losses resulting from fraudulent activities that could adversely impact our financial performance and results of operations.

As a bank, we are susceptible to fraudulent activity that may be committed against us or our customers, which may result in financial losses or increased costs to us or our customers, disclosure or misuse of our information or our customer information, misappropriation of assets, privacy breaches against our customers, litigation or damage to our reputation. We are most susceptible to fraud and compliance risk in connection with the origination of loans, automated clearing house transactions, wire transactions, automated teller machine transactions, checking transactions, debit cards that we have issued to our customers and through our online banking portals.

We maintain a system of internal controls and insurance coverage to mitigate against such risks, including data processing system failures and errors, and customer fraud. If our internal controls fail to prevent or detect any such occurrence, or if any resulting loss is not insured or exceeds applicable insurance limits, it could have a material adverse effect on our business, financial condition and results of operations.

The cost of additional finance and accounting systems, procedures and controls to satisfy our public company reporting requirements will increase our expenses.

The obligations of being a public company, including the substantial public reporting obligations, will require significant expenditures and place additional demands on our management team. We have made, and will continue to make, changes to our internal controls and procedures for financial reporting and accounting systems to meet our reporting obligations as a public company. However, the measures we take may not be sufficient to satisfy our obligations as a public company. Section 404 of the Sarbanes-Oxley Act of 2002 requires annual management assessments of the effectiveness of our internal control over financial reporting, starting with the second annual report that we would expect to file with the Securities and Exchange Commission. Any failure to achieve and maintain an effective internal control environment could have a material adverse effect on our business and stock price. In addition, we may need to hire additional compliance, accounting and financial staff with appropriate public company experience and technical knowledge, and we may not be able to do so in a timely fashion. As a result, we may need to rely on outside consultants to provide these services for us until qualified personnel are hired. These obligations will increase our operating expenses and could divert our management’s attention from our operations.

Risks Related to Accounting Matters

Changes in accounting standards could affect reported earnings.

The bodies responsible for establishing accounting standards, including the Financial Accounting Standards Board, the SEC and other regulatory bodies, periodically change the financial accounting and reporting guidance that govern the preparation of our financial statements. These changes can be hard to predict and can materially impact how we record and report our financial condition and results of operations. In some cases, we could be required to apply new or revised guidance retroactively.

If management’s estimates and assumptions are incorrect, it may have a material impact on our consolidated financial statements and our financial condition or operating results.

In preparing the periodic reports we are required to file under the Exchange Act, including our consolidated financial statements, our management is and will be required under applicable rules and regulations to make estimates and assumptions as of a specified date. These estimates and assumptions are based on management’s best estimates and experience as of that date and are subject to substantial risk and uncertainty. Materially different results may occur as circumstances change and additional information becomes known. The most significant areas requiring significant estimates and assumptions by management include our evaluation of the adequacy of our allowance for loan losses.

34

Other Risks Related to Our Business

Legal and regulatory proceedings and related matters could adversely affect us.

We have been and may in the future become involved in legal and regulatory proceedings. We consider most of the proceedings to be in the normal course of our business or typical for the industry; however, it is inherently difficult to assess the outcome of these matters, and we may not prevail in any proceedings or litigation. There could be substantial costs and management diversion in such litigation and proceedings, and any adverse determination could have a materially adverse effect on our business, brand or image, or our financial condition and results of our operations.

Societal responses to climate change could adversely affect our business and performance, including indirectly through impacts on our customers.

Concerns over the long-term effects of climate change have led and will continue to lead to governmental efforts around the world to mitigate those impacts. Consumers and businesses also may voluntarily change their behavior as a result of these concerns. We and our customers will need to respond to new laws and regulations as well as consumer and business preferences resulting from climate change concerns. We and our customers may face cost increases, asset value reductions and operating process changes. The impact on our customers will likely vary depending on their specific attributes, including reliance on or role in carbon intensive activities. Among the impacts to us could be a drop in demand for our products and services, particularly in certain sectors. In addition, we could face reductions in creditworthiness on the part of some customers or in the value of assets securing loans. Our efforts to take these risks into account in making lending and other decisions, including by increasing our business with climate-friendly companies, may not be effective in protecting us from the negative impact of new laws and regulations or changes in consumer or business behavior.

We are a community bank and our ability to maintain our reputation is critical to the success of our business, and the failure to do so may materially adversely affect our performance.

We are a community bank, and our reputation is one of the most valuable components of our business. A key component of our business strategy is to rely on our reputation for customer service and knowledge of local markets to expand our presence by capturing new business opportunities from existing and prospective customers in our market area and contiguous areas. As such, we strive to conduct our business in a manner that enhances our reputation. This is done, in part, by recruiting, hiring and retaining employees or by retaining, appointing or electing directors who share our core values of being an integral part of the communities we serve, delivering superior service to our customers and caring about our customers and employees. If our reputation is negatively affected by the actions of our employees or directors, by our inability to conduct our operations in a manner that is appealing to current or prospective customers, or otherwise, our business and, therefore, our operating results may be materially adversely affected.

Risks Related to the Ownership of Stock

Persons who have purchased stock in the offering will own a minority of CFSB Bancorp’s common stock and cannot exercise voting control over most matters put to a vote of stockholders.

Public stockholders own a minority of the outstanding shares of CFSB Bancorp’s common stock. As a result, stockholders other than 15 Beach, MHC cannot exercise voting control over most matters put to a vote of stockholders. 15 Beach, MHC owns a majority of CFSB Bancorp’s common stock and, through its board of directors, can exercise voting control over most matters put to a vote of stockholders. The same directors and officers who manage Colonial Federal Savings Bank also manage CFSB Bancorp and 15 Beach, MHC. The board of directors and officers of 15 Beach, MHC must ensure that the interests of depositors of Colonial Federal Savings Bank (as members of 15 Beach, MHC) are represented and considered in matters put to a vote of stockholders of CFSB Bancorp. Therefore, 15 Beach, MHC may take action that the public stockholders believe to be contrary to their interests. For example, 15 Beach, MHC may exercise its voting control to defeat a stockholder nominee for election to the board of directors of CFSB Bancorp.

In addition, stockholders will not be able to force a merger or second-step conversion transaction without the consent of 15 Beach, MHC since such transactions also require the approval of a majority of all of the outstanding

35

voting stock of CFSB Bancorp, which can only be achieved if 15 Beach, MHC votes to approve such transactions. Some stockholders may desire a sale or merger transaction, since stockholders typically receive a premium for their shares, or a second-step conversion transaction, since, on a fully converted basis, most full stock institutions tend to trade at higher multiples than mutual holding companies. Stockholders could, however, prevent a second-step conversion or the implementation of equity incentive plans because under current regulations and policies, such matters also require the separate approval of the stockholders other than 15 Beach, MHC.

Our common stock is not heavily traded, and the stock price may fluctuate significantly.

Our common stock is traded on The NASDAQ Stock Market. Certain brokers currently make a market in the common stock, but such transactions are infrequent and the volume of shares traded is relatively small. Management cannot predict whether these or other brokers will continue to make a market in our common stock. Prices on stock that is not heavily traded can be more volatile than heavily traded stock. Factors such as our financial results, the introduction of new products and services by us or our competitors, publicity regarding the banking industry, and various other factors affecting the banking industry may have a significant impact on the market price of the shares of the common stock. Management also cannot predict the extent to which an active public market for our common stock will develop or be sustained in the future. Accordingly, stockholders may not be able to sell their shares of our common stock at the volumes, prices, or times that they desire.

Federal Reserve Board regulations and policy effectively prohibit 15 Beach, MHC from waiving the receipt of dividends, which will likely preclude us from paying any dividends on our common stock.

CFSB Bancorp’s board of directors have the authority to declare dividends on our common stock subject to statutory and regulatory requirements. We currently intend to retain all our future earnings, if any, for use in our business and do not expect to pay any cash dividends on our common stock in the foreseeable future. Any future determination to pay cash dividends will be made by our board of directors and will depend upon our financial condition, results of operations, capital requirements, restrictions under Federal Reserve Board regulations and policy, our business strategy and other factors that our board of directors deems relevant.

Under Federal Reserve Board regulations and policy, if CFSB Bancorp pays dividends to its public stockholders, it also would be required to pay dividends to 15 Beach, MHC, unless 15 Beach, MHC waives the receipt of such dividends. Federal Reserve Board regulations implemented after the enactment of the Dodd–Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) effectively prohibit federally-chartered mutual holding companies from waiving dividends declared by their subsidiaries. See “Supervision and Regulation—Holding Company Regulation—Waivers of Dividends by 15 Beach, MHC” for a further discussion of the applicable requirements related to the potential waiver of dividends by a mutual holding company. Unless Federal Reserve Board regulations and policy change by allowing 15 Beach, MHC to waive the receipt of dividends declared by CFSB Bancorp without diluting minority stockholders, it is unlikely that CFSB Bancorp will pay any dividends.

Various factors may make takeover attempts more difficult to achieve.

Stock banks or their holding companies, as well as individuals, may not acquire control of a mutual holding company, such as CFSB Bancorp. As a result, the only persons that may acquire control of a mutual holding company are other mutual savings institutions or mutual holding companies. Accordingly, it is very unlikely that CFSB Bancorp would be subject to any takeover attempt by activist stockholders or other financial institutions. There also are provisions in our charter and bylaws that may be used to delay or block a takeover attempt, including a provision that prohibits any person, other than 15 Beach, MHC, from voting more than 10% of the shares of common stock outstanding. In addition, federal banking laws, including regulatory approval requirements, could make it more difficult for a third party to acquire control of CFSB Bancorp without our board of directors’ prior approval.

Under Federal Reserve Board regulations, for a period of three years following completion of the stock offering, no person may directly or indirectly acquire or offer to acquire beneficial ownership of more than 10% of our common stock without prior approval of the Federal Reserve Board. In addition, under federal law, subject to certain exemptions, a person, entity or group must notify the Federal Reserve Board before acquiring control of a savings and loan holding company. Acquisition of 10% or more of any class of voting stock of a savings and loan holding company creates a rebuttable presumption that the acquirer “controls” the savings and loan holding company. Also, a savings and loan holding company must obtain the prior approval of the Federal Reserve Board before, among other things,

36

acquiring direct or indirect ownership or control of more than 5% of any class of voting shares of any financial institution holding company or bank, including Colonial Federal Savings Bank.

In addition, a section in CFSB Bancorp’s charter provides that for a period of five years from the closing of the offering, no person, other than 15 Beach, MHC, may directly or indirectly offer to acquire or acquire the beneficial ownership of more than 10% of any class of equity security of CFSB Bancorp, held by persons other than 15 Beach, MHC, and that any shares acquired in excess of this limit will not be entitled to be voted and will not be counted as voting stock in connection with any matters submitted to the stockholders for a vote.

Taken as a whole, these statutory provisions and provisions in our charter and bylaws make it very difficult for any potential acquiror from acquiring control of CFSB Bancorp without the approval of our board of directors, which could adversely affect the market price of our common stock.
