You are cordially invited to attend the special meeting of the shareholders of CFSB Bancorp, Inc. (the “Company”). The meeting will be held on [Meeting Day], [Meeting Date], at :00 p.m., local time, at the [Meeting Location], Massachusetts.

(“Hometown Financial”), Hometown Financial Acquisition Corp. II, a wholly owned subsidiary of Hometown Financial formed solely to facilitate the Merger (“Merger Sub”) and 15 Beach, MHC, the Company’s mutual holding company parent. The Company, 15 Beach, MHC and Colonial Federal Savings Bank, the wholly owned subsidiary of the Company (“Colonial Federal”), are sometimes collectively referred to as “Colonial” herein.

Pursuant to the Merger Agreement, 15 Beach, MHC will merge with Hometown MHC, with Hometown MHC as the surviving corporation (the “MHC Merger”). After the MHC Merger, the Company will merge with and into Merger Sub, with the Company as the surviving corporation and a wholly owned subsidiary of Hometown Financial (the “Merger”). Following the Merger, the Company will merge with and into Hometown Financial, with Hometown Financial as the surviving corporation (the “Second Step Merger”), and following the Second Step Merger, Colonial Federal will merge with and into North Shore Bank, a wholly owned subsidiary of Hometown Financial (the “Bank Merger”).

THE MERGER

Overview of the Transaction

We propose a business combination in which 15 Beach, MHC will merge with Hometown MHC, with Hometown MHC as the surviving corporation (the “MHC Merger”). Following the MHC Merger, the Company will merge with and into Merger Sub, with the Company as the surviving entity. Following the Merger, the Company will merge with and into Hometown Financial, with Hometown Financial as the surviving corporation (the “Second Step Merger”), and following the Second Step Merger, Colonial Federal will merge with and into North Shore Bank (the “Bank Merger”), with North Shore Bank as the surviving entity.

Each Share of Company Common Stock Will Be Exchanged for $14.25 in Cash

As a Company shareholder, upon the closing of the Merger, each of your shares of our common stock will automatically be converted into the right to receive $14.25 in cash. Shares of our common stock that are held by 15 Beach, MHC, Hometown Financial, or any of their respective subsidiaries will be cancelled without receiving cash consideration.

How to Receive Cash in Exchange for Your Company Stock Certificates

To receive cash in exchange for your shares of Company common stock, you will need to surrender your Company stock certificates. You should not return your Company stock certificates with the enclosed proxy, and you should not send your stock certificates to the exchange agent until you receive the letter of transmittal. Hometown Financial’s paying agent will send you written instructions for surrendering your Company stock certificates as promptly as practicable following the closing of the Merger. If your shares of Company common stock are held in “street” name, you broker, bank or nominee will process the exchange on your behalf.

Our common stock trades on the Nasdaq Capital Market under the symbol “CFSB.” During the 60-day period prior to the announcement of the Merger, our common stock closed as low as $7.40 per share and as high as $8.19 per share. On May 20, 2025, which was the last trading day before we announced the Merger, our common stock closed at $8.19 per share. On [●], 2025, which is the last practicable trading day before the printing of this proxy statement, our common stock closed at $[●] per share.

Tax Consequences of the Merger

The receipt of the merger consideration in exchange for shares of Company common stock will generally be a taxable transaction for U.S. federal income tax purposes. In general, you will recognize any gain or loss equal to the difference between the amount of cash you receive in the Merger and the adjusted tax basis of your shares of Company common stock. See “Proposal 1—Approval of the Merger Agreement—The Merger—Material Federal Income Tax Consequences of the Merger.”

This tax treatment may not apply to all shareholders. Determining the actual tax consequences of the Merger to you can be complicated. You should consult your own tax advisor for a full understanding of the Merger’s tax consequences that are particular to you.

The Company’s Board of Directors Recommends That
Shareholders Approve the Merger

Our board of directors believes that the Merger is fair and in our shareholders’ best interests, and unanimously recommends that you vote “FOR” the proposal to approve the Merger Agreement and the Merger. For a discussion of the circumstances surrounding the Merger and the factors considered by our board of directors in approving the Merger Agreement, see “Proposal 1—Approval of the Merger Agreement—The Merger—The Company’s Reasons for the Merger.”

The Opinion of the Company’s Financial Advisor
in connection with the Merger

In connection with the Merger, the Company’s financial advisor, Piper Sandler & Co. (“Piper Sandler”), delivered a written opinion, dated May 20, 2025, to the Company’s board of directors as to the fairness, from a financial point of view and as of the date of the opinion, to the holders of the Company’s common stock (other than 15 Beach, MHC) of the merger consideration to be received by such shareholders in the Merger. The full text of the opinion, which describes the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by Piper Sandler in preparing the opinion, is attached as Annex B to this proxy statement. The opinion was solely for the information of, and was directed solely to, the Company’s board of directors (solely in its capacity as such) in connection with its consideration of the financial terms of the Merger. Piper Sandler’s opinion is included in this proxy statement solely because it was considered by the Company’s board of directors for the aforementioned purpose and is not to be relied upon by any other entity or person or used for any other purpose. The opinion did not address the underlying business decision of the Company to engage in the Merger or enter into the Merger Agreement or constitute a recommendation to the Company’s board of directors in connection with the Merger, and it does not constitute a recommendation to any holder of the Company’s common stock as to how to vote in connection with the Merger or any other matter.

Interests of Company’s Directors and Officers
in the Merger That Differ From Your Interests

Certain of our directors and officers have interests in the Merger that are different from, or are in addition to, their interests as shareholders in the Company. The members of our board of directors knew about these additional interests, and considered them, when they approved the Merger. These include:

•

each of Michael E. McFarland, President and Chief Executive Officer of the Company, and Susan J. Shea, Chief Operating Officer and Treasurer of the Company, entering into settlement agreements with Colonial that will provide for lump sum cash payments to the executives in exchange for the termination of their employment agreements with Colonial;

•

Mr. McFarland entering into a restrictive covenant agreement with Hometown Financial and North Shore Bank that provides for an additional cash payment at the effective time of the Merger;

•

Ms. Shea entering into a consulting agreement with Hometown Financial that provides for cash payments over an eight-month period following the effective time of the Merger;

•

Hometown Financial agreeing to honor obligations under existing change in control agreements, supplemental retirement agreements and supplemental retirement plan and life insurance arrangements, which will result in either lump sum cash payments or installment cash payments being made to directors and officers;

•

the acceleration of vesting of Company outstanding stock options and the receipt by the holders of such options of a cash payment equal to $14.25 less the exercise price of such option for each option;

•

the acceleration of vesting of outstanding restricted stock awards, each of which will receive the $14.25 merger consideration;

•

provisions in the Merger Agreement that provide for the possibility of retention bonuses to be paid to Colonial Federal employees (potentially including officers) to remain employed at Colonial Federal through the effective time of the Merger or for an interim period thereafter;

•

the consideration by North Shore Bank of the appointment of current Colonial Federal board members to the board of North Shore Bank following the effective time of the Merger, although North Shore Bank is under no obligation to do so; and

•

provisions in the Merger Agreement relating to the rights of directors and officers of 15 Beach, MHC, the Company and Colonial Federal to continued indemnification coverage and continued coverage under directors’ and officers’ liability insurance policies.

Regulatory Approval Needed to Complete the Merger

We cannot complete the Merger unless the required regulatory approvals have been received. North Shore Bank filed the necessary regulatory applications with the Board of Governors of the Federal Reserve System (the “FRB”) on [●], 2025 and the Massachusetts Division of Banks on [●], 2025. Hometown MHC and Hometown Financial filed a holding company application with the FRB on [●], 2025 in connection with the transaction.

No Dissenters’ or Appraisal Rights

Shareholders of the Company do not have dissenters’ or appraisal rights in connection with the Merger.

THE MERGER AGREEMENT

A copy of the Merger Agreement is provided as Annex A to this proxy statement. Please read the entire Merger Agreement carefully. It is the legal document that governs the Merger.

Conditions to Completing the Merger

The completion of the Merger depends on a number of conditions being met. These conditions include, among other items:

•

•

receipt of approval by Hometown MHC’s corporators;

•

neither 15 Beach, MHC nor the Company having experienced a materially adverse effect;

•

the absence of any conditions in the required regulatory approvals that would (1) prohibit or materially limit the ownership or operation by Hometown of all or any material portion of the business or assets of the Colonial or of Hometown, (2) compel Hometown or Colonial to dispose of or hold separate all or any material portion of its business or assets or (3) compel Hometown to take any action, or commit to take any action, or agree to any condition or request, if the prohibition, limitation, condition or other requirement described in clauses (1) through (3) above could reasonably be expected to have a material adverse effect on Hometown or the combined businesses and operations of Hometown Financial’s banking subsidiaries and Colonial Federal, taken as a whole (referred to herein as a “Burdensome Condition”); and

•

Colonial Federal having entered into the bank merger agreement.

See “The Merger Agreement—Conditions to Completing the Merger” below for a discussion of all of the conditions to completing the Merger. We cannot be certain when or if the conditions to the Merger will be satisfied or waived, or that the Merger will be completed.

Regarding the required regulatory approvals, North Shore Bank filed the necessary regulatory applications with the FRB on [●], 2025 and the Massachusetts Division of Banks on [●], 2025. Hometown MHC and Hometown Financial filed the necessary application with the FRB on [●], 2025.

Agreement Not to Solicit Other Proposals

Between the signing of the Merger Agreement and the completion of the Merger or the termination of the Merger Agreement, the Company has agreed (and will use its reasonable best efforts to cause its subsidiaries and representatives) not to (1) solicit, initiate, induce, encourage or take any action (including furnishing information) to facilitate any competing proposal with a third party, (2) continue or otherwise participate in any discussions or negotiations, or otherwise communicate in any way with any person other than to notify such person of the existence of the non-solicitation provisions, (3) approve, endorse or recommend any third-party proposal, or (4) enter into or consummate any agreement, agreement in principle arrangement, letter of intent or understanding contemplating any third-party proposal or requiring it to abandon, terminate or fail to consummate the transactions contemplated hereby.

Notwithstanding these restrictions, at any time before shareholder approval of the Merger, the Company may participate in discussions or negotiations regarding an acquisition proposal or furnish non-public information with respect to the Company or otherwise relating to an acquisition proposal with a third party who makes an unsolicited proposal, provided that, among other things:

•

our board of directors concludes, in good faith, after considering the advice of the Company’s financial advisor and with respect to financial matters, our financial advisor, the acquisition proposal constitutes or could reasonably be likely to result in a proposal superior to Hometown Financial’s proposal, as set forth in the Merger Agreement;

•

the Company has not otherwise breached its covenants not to solicit acquisition proposals as set forth in the Merger Agreement;

•

our board of directors determines, in good faith, after considering the advice of our outside counsel, that taking such action would be required for the Company’s directors to comply with their fiduciary duties to the Company’s shareholders under applicable law; and

•

if furnishing information to a third party, the Company has first given Hometown Financial written notice of the identity of the third party and the Company obtains a confidentiality agreement from the soliciting party no less favorable to the Company than those in its confidentiality agreement with Hometown Financial.

See “The Merger Agreement—Other Provisions of the Merger Agreement—Agreement Not to Solicit Other Proposals” below for a

discussion of what constitutes an “acquisition proposal” and a “superior proposal.”

We May Amend the Terms of the Merger and
Waive Some Conditions

The Company and Hometown Financial may agree to amend the Merger Agreement, and each of us may waive our right to require the other party to adhere to the terms and conditions of the Merger Agreement that are beneficial to the waiving party.

Terminating the Merger Agreement

The Company and Hometown Financial may mutually agree at any time to terminate the Merger Agreement. In addition, either we or Hometown Financial may decide, without the consent of the other, to terminate the Merger Agreement if:

•

the Company’s shareholders do not approve the Merger, or, if their approval is required for the Merger, the members of 15 Beach, MHC do not approve the Merger or Hometown MHC’s corporators do not approve the Merger; provided in each case a party cannot terminate the Merger if it did not comply with its obligations to hold the require meeting and solicit votes;

•

regulatory approval is denied, or if a regulatory approval contains a Burdensome Condition;

•

the Merger is not consummated by March 31, 2026 (unless the failure to consummate is due to the action or failure to act by the party seeking to terminate the Merger Agreement); or

•

Hometown Financial may also terminate the Merger Agreement if the Company does not comply with its non-solicitation requirements or changes its recommendation to the Company shareholders regarding the Merger, or it or 15 Beach, MHC breach their obligations to call meetings of their shareholders or members, as required.

We may also terminate the Merger Agreement to enter into an agreement with respect to a superior acquisition proposal, but only if, among other things, we have complied with our obligation not to solicit competing proposals. See “Summary—The Merger Agreement—Termination Fees” and “The Merger Agreement—Other Provisions of the Merger Agreement—Agreement Not to Solicit Other Proposals” below for a discussion of situations requiring the Company’s payment of a termination fee to Hometown Financial.

Termination Fee

Under certain circumstances, we may be required to pay Hometown Financial a fee of $1,550,000. Specifically, the Company must pay the

fee to Hometown Financial if the Merger Agreement is terminated under the following circumstances:

•

the Company terminates the Merger Agreement to enter into an agreement with respect to a superior acquisition proposal;

•

Hometown Financial terminates the Merger Agreement because the Company breaches its agreements in the Merger Agreement with respect to its solicitation of other acquisition proposals or because 15 Beach, MHC or the Company breach their obligation to hold a meeting of Company shareholders or 15 Beach, MHC members (if required) to vote on the Merger Agreement; provided at the time Hometown Financial is not in material breach of any representation, warranty or material covenant in the Merger Agreement; or

•

if (1) Hometown Financial terminates the Merger Agreement because (a) the Company’s shareholders do not approve the Merger, or, if their approval is required for the Merger, the members of 15 Beach, MHC do not approve the Merger or Hometown MHC’s corporators do not approve the Merger; provided in each case a party cannot terminate the Merger if it did not comply with its obligations to hold the require meeting and solicit votes or (b) there is a breach by the other party of any representation, warranty, covenant or agreement contained in the Merger Agreement such that certain conditions to closing of the Merger cannot be met, which breach cannot be cured, or has not been cured within 30 days after the giving of written notice to such party of such breach if the breach giving rise to the termination was knowing or intentional; (2) at the time Hometown Financial is not in material breach of any representation, warranty or material covenant in the Merger Agreement; (3) either before the Company shareholder meeting or 15 Beach, MHC member meeting, or before the date of termination, a third-party acquisition proposal has been publicly announced, disclosed or communicated and not withdrawn at least two business days before the applicable meeting; and (4) within 12 months of the termination of the Merger Agreement the Company consummates or enters into an agreement with a third party, then the payment will be made to Hometown Financial.

QUESTIONS AND ANSWERS ABOUT THE MERGER

What am I being asked to vote on and how does the board of directors recommend that I vote?

You are being asked to vote “FOR” the approval of the Merger Agreement and the Merger and “FOR” a proposal to approve the adjournment or postponement of the special meeting, if necessary or appropriate, to solicit additional proxies in favor of the Merger Agreement and the Merger (the “Adjournment Proposal”). The Company’s board of directors has determined that the proposed Merger is in the best interests of the shareholders of the Company, has approved the Merger Agreement and unanimously recommends that shareholders vote “FOR” the approval of the Merger Agreement and “FOR” the Adjournment Proposal.

What vote is required to adopt the Merger Agreement?

What will I receive in the Merger?

Under the Merger Agreement, each share of Company common stock you own will be converted into the right to receive $14.25 in cash. Shares of Company common stock held by Hometown Financial or 15 Beach, MHC or their respective subsidiaries will be cancelled without receiving cash consideration. Following completion of the Merger, you will no longer have any rights or interests in the Company.

What are the tax consequences of the Merger to me?

Company shareholders will generally recognize a gain or loss for federal income tax purposes on each share of Company common stock exchanged for the merger consideration in an amount equal to the difference between the adjusted tax basis in each share of Company common stock and the value of the per share merger consideration received in connection with the Merger. Company shareholders are urged to consult their own tax advisor for a full understanding of the tax consequences of the Merger.

How do I exchange my Company stock certificates?

Please do not send in your stock certificates at this time. You will receive instructions on where and how to surrender your Company stock certificates from Hometown Financial’s paying agent after the Merger is completed. In any event, you should not forward your Company stock certificates with your proxy card.

What should I do now?

After you have carefully read this document, please vote.

You may vote your shares by completing and signing the enclosed proxy card and returning it in the enclosed postage-paid envelope or you may vote at the special meeting. Alternatively, you may choose to vote your shares using the Internet or telephone voting options explained on your proxy card. You should complete and return the proxy card accompanying this document, or vote using the Internet or telephone voting options, to ensure that your vote is counted at the special meeting, or at any adjournment or postponement of the special meeting, regardless of whether you plan to attend the special meeting.

Shareholders whose shares are held in the name of a broker, bank or other holder of record must vote in the manner directed by such holder. Check your proxy card or the information forwarded by your broker, bank or other holder of record to see which options are available to you.

If you do not return a properly executed proxy card or vote via telephone or the Internet and do not vote at the special meeting, this will have the same effect as a vote against the Merger Agreement. If you sign, date and return your proxy card, but you do not indicate how you want to vote, your proxy will be voted in favor of approval of the Merger Agreement and the Adjournment Proposal. You may change your vote or revoke your proxy before the special meeting by filing with the Company’s Corporate Secretary a duly executed revocation of proxy, submitting a new proxy card with a later date, voting again via telephone or the Internet or at the special meeting.

If my shares are held in “street name” by my broker, bank or nominee, will my broker, bank or nominee automatically vote my shares for me?

No. Your broker, bank or nominee will not be able to vote your shares of Company common stock unless you provide instructions on how to vote. You should instruct your broker, bank or nominee how to vote your shares by following the procedures your broker provides. If you do not provide instructions to your broker, bank or nominee, your shares will not be voted, and this will have the effect of voting against adoption of the Merger Agreement. Please check the voting form used by your broker, bank or nominee to see if it offers telephone or Internet voting.

What happens if I sell my shares of common stock before the special meeting?

The record date for the special meeting will be earlier than the effective time of the Merger. If you transfer your shares of common stock after the record date but before the special meeting, you will, unless other arrangements are made, retain your right to vote at the special meeting but will not be entitled to receive the merger consideration for such shares. You will be entitled to receive the merger consideration only if the Merger is completed and only if you own shares of our common stock at the time the Merger is completed.

What do I do if I lost my stock certificates?

You should review the letter of transmittal for instructions on how to proceed if you have lost your Company stock certificates. If your Company stock certificates have been lost, stolen or destroyed, you will have to prove your ownership of these certificates and that they were lost, stolen or destroyed and, if required by the paying agent or Hometown Financial, you may have to post a bond in such amount as the paying agent may direct as indemnity against any claim that may be made against it, the Company, or another party with respect to such certificate, before you receive any payment for the shares represented by that certificate.

THE SPECIAL MEETING

This proxy statement is furnished in connection with the solicitation of proxies by the board of directors of the Company to be used at the special meeting of shareholders.

Place, Date and Time

The special meeting will be held at [Meeting Location], Quincy, Massachusetts 02170 on [Meeting Day], [Meeting Date], 2025, at :00 p.m., local time.

Purpose of the Meeting

The purpose of the meeting is to consider and vote upon proposals to: (1) approve the Merger Agreement and the Merger; and (2) approve the adjournment or postponement of the special meeting, if necessary or appropriate, to solicit additional proxies in favor of the Merger Agreement and the Merger (the “Adjournment Proposal”).

Who Can Vote at the Meeting; Record Date

You are entitled to vote your Company common stock only if the records of the Company show that you held your shares as of the close of business on [Record Date]. You are entitled to one vote at the special meeting for each share of the Company’s common stock that you owned on the record date. The number of shares you own (and may vote) is listed on your proxy card.

Our Charter provides that record holders of our common stock who beneficially own, either directly or indirectly, more than 10% of our outstanding shares (other than 15 Beach, MHC) are not entitled to any vote with respect to the shares held in excess of the 10% limit.

As of the close of business on [Record Date], 6,548,575 shares of Company common stock were outstanding.

Ownership of Shares

You may own your shares of Company common stock in one or more of the following ways:

•

Directly in your name as the shareholder of record;

•

Indirectly through a broker, bank or other holder of record in “street name”; or

•

Indirectly through the Colonial Federal Savings Bank 401(k) Savings Plan (the “401(k) Plan”) or the Colonial Federal Savings Bank Employee Stock Ownership Plan (the “ESOP”).

If your shares are registered directly in your name, you are the holder of record of those shares and we are sending these proxy materials directly to you. As the holder of record, you have the right to give your proxy directly to us to vote at the annual meeting or you may vote in person at the annual meeting.

If you hold your shares in “street name,” you are considered the beneficial owner of your shares and your broker, bank or other holder of record is sending these proxy materials to you. As the beneficial owner, you have the right to direct your broker, bank or other holder of record how to vote by completing a voting instruction form provided by your broker, bank or other holder of record that accompanies your proxy materials. Your broker, bank or other holder of record may allow you to provide voting instructions by telephone or by the Internet. Refer to the voting instruction form that accompanies your proxy materials. If you want to vote your shares of common stock held in street name in person at the annual meeting, you must obtain a written proxy in your name from the broker, bank or other holder who is the record holder of your shares.

If you own shares of common stock indirectly through the 401(k) Plan or are a participant in the ESOP, see “Participants in the ESOP and 401(k) Plan” below.

Attending the Meeting

Shareholders are invited to attend the special meeting. If you hold your shares in street name, you will need proof of ownership to be admitted to the meeting. Examples of proof of ownership are a recent brokerage account statement or a letter from your bank or broker.

Quorum and Vote Required

Quorum. The special meeting will be held only if there is a quorum present. We will have a quorum and will be able to conduct the business of the special meeting if a majority of the outstanding shares of the Company entitled to vote, represented in person or by proxy, are present at the meeting. If you return valid proxy instructions or attend the meeting in person, your shares will be counted to determine whether there is a quorum present, even if you abstain from voting. Broker non-votes, if any, will also be counted to determine the existence of a quorum. A broker non-vote occurs when a broker, bank or other nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received voting instructions from the beneficial owner. Broker non-votes occur when there are both routine and non-routine proposals at a meeting. Because none of the proposals to be voted on at the special meeting are routine matters for which brokers may have discretionary authority to vote, the Company does not expect any broker non-votes at the special meeting and does not expect any broker non-votes to count towards the special meeting quorum.

Votes Required.

Proposal 1. The approval of the Merger Agreement requires the affirmative vote of (1) at least a majority of the outstanding shares of Company common stock entitled to vote, including the shares of Company common stock held by 15 Beach, MHC, and (2) a majority of the outstanding shares of Company common stock entitled to vote, excluding the shares of Company common stock held by 15 Beach, MHC. Abstentions and broker non-votes will have the same effect as a vote “Against” the approval of the Merger Agreement.

Proposal 2. The Adjournment Proposal requires the affirmative vote of at least a majority of the shares of Company common stock represented at the meeting and entitled to vote on the subject matter. Abstentions will have the same effect as a vote “Against” the proposal, while broker non-votes will have no effect on this proposal.

Shares Held by Directors and Officers of the Company; Voting Agreements

All of our directors, executive officers and our parent company, 15 Beach, MHC, each entered into voting agreements with Hometown Financial requiring each to vote all of the shares of Company common stock each owns in favor of the proposal to approve the Merger Agreement. As of the record date for the special meeting, directors and executive officers of the Company beneficially owned, in the aggregate, 381,799 shares, or 5.8% of the outstanding shares of the Company’s common stock. Including the 3,586,903 shares held by 15 Beach, MHC, 3,968,702 shares of Company stock having the power to cast approximately 60% of the total votes eligible to be cast at the special meeting are subject to the voting agreements.

15 Beach, MHC’s presence in person or by proxy at the special meeting is sufficient to guarantee that quorum will be met at the special meeting. In addition, 15 Beach, MHC’s vote in favor of the proposal to approve the Merger Agreement would represent a vote of at least a majority of the outstanding shares of Company stock entitled to vote. 15 Beach, MHC’s vote would therefore satisfy one of the two voting standards that are required to approve the Merger Agreement proposal. See “—Votes Required” above for more information.

Voting by Proxy

The board of directors of the Company is sending you this proxy statement to request that you allow your shares of Company common stock to be represented at the special meeting by the persons named in the enclosed proxy card. All shares of Company common stock represented at the special meeting by properly executed proxies will be voted according to the instructions indicated on the proxy card. You may also vote your shares via the Internet or by telephone. Specific instructions for Internet or telephone voting are set forth on the enclosed proxy card. The deadline for voting by telephone or via the Internet is 11:59 p.m., local time on [●], 2025.

If you sign, date and return a proxy card without giving voting instructions, your shares will be voted as recommended by the Company’s board of directors. The board of directors unanimously recommends a vote “FOR” the approval of the Merger Agreement and the Merger; and “FOR” the Adjournment Proposal.

If any matter not described in this proxy statement is properly presented at the special meeting, the persons named in the proxy card will use their judgment to determine how to vote your shares. If the special meeting is postponed or adjourned, Company common stock may be voted by the persons named in the proxy card on the new special meeting date as well, unless you have revoked your proxy. The Company does not know of any other matters to be presented at the special meeting.

If your Company common stock is held in “street name,” you will receive instructions from your broker, bank or other nominee that you must follow to have your shares voted. Your broker or bank may allow you to deliver your voting instructions via the Internet or by telephone. Please see the instruction form that accompanies this proxy statement.

Voting via the Internet or by Telephone

Instead of voting by mailing a proxy card, registered shareholders can vote their shares of Company common stock via the Internet or by telephone. The Internet and telephone voting procedures are designed to authenticate shareholders’ identities, allow shareholders to provide their voting instructions and confirm that their instructions have been recorded properly. Specific instructions for Internet and telephone voting are set forth on the proxy card. The deadline for voting via the Internet or by telephone is 11:59 p.m., Eastern Time, on [●], 2025.

How to Revoke Your Proxy

You may revoke your proxy at any time before the vote is taken at the meeting. To revoke your proxy you must either advise the Corporate Secretary of the Company in writing before the vote is taken at the special meeting, deliver a later dated proxy card, or attend the special meeting and vote your shares in person. Attendance at the special meeting will not in itself constitute revocation of your proxy.

The Company’s Corporate Secretary can be reached at the following address:

Participants in the ESOP and the 401(k) Plan

If you are a participant in the ESOP, you will receive a voting instruction card that reflects all the shares that you may direct the ESOP trustee to vote on your behalf under the ESOP. Under the terms of the ESOP, the ESOP

trustee votes all shares held by the ESOP, but you may direct the trustee how to vote the shares of Company common stock allocated to your ESOP account. The ESOP trustee will vote all unallocated shares of Company common stock held by the ESOP and all allocated shares for which no voting instructions are received in the same proportion as shares for which it has received timely voting instructions.

If you hold Company common stock in the 401(k) Plan, you will receive a voting instruction card that reflects all shares that you may direct the 401(k) Plan trustee to vote on your behalf under the 401(k) Plan. Under the terms of the 401(k) Plan, you may direct the 401(k) Plan trustee how to vote the shares allocated to your account. If the 401(k) Plan trustee does not receive your voting instructions, the 401(k) Plan trustee will be instructed to vote your shares in the same proportion as the voting instructions received from other 401(k) Plan participants.

The deadline for returning your voting instruction cards to the ESOP trustee and/or the 401(k) Plan trustee is [●], 2025.

Proxy Solicitation Costs

The Company will pay the cost of this proxy solicitation. In addition to the solicitation of proxies by mail, Laurel Hill Advisory Group, LLC, a proxy solicitation firm, will assist the Company in soliciting proxies for the special meeting. The Company will pay Laurel Hill Advisory Group, a fee of $7,000, plus reasonable out of pocket expenses and additional fees for any necessary shareholder phone calls, for these services. Additionally, directors, officers and employees of the Company may solicit proxies personally or by telephone without receiving additional compensation. None of these persons will receive additional or special compensation for soliciting proxies. The Company will reimburse brokers, banks, nominees and other fiduciaries for their expenses in sending proxy materials to their customers who are beneficial owners and obtaining their voting instructions.

APPROVAL OF THE MERGER AGREEMENT

THE MERGER

Hometown Financial Acquisition Corp. II. Hometown Financial Acquisition Corp. II (“Merger Sub”) is a Massachusetts corporation and wholly-owned subsidiary of Hometown Financial formed solely to facilitate in the Merger.

Form of the Merger

The boards of directors of the Company and Hometown Financial have each unanimously approved the Merger Agreement and the transactions contemplated under the Merger Agreement. Upon completion of the Merger, each share of Company common stock, excluding the shares of common stock held by 15 Beach, MHC and Hometown Financial and their respective subsidiaries, will be converted into the right to receive $14.25 in cash (without interest), and Company shareholders will no longer have any right or interest in the Company.

As soon as possible after the conditions to consummation of the Merger have been satisfied or waived, and unless the Merger Agreement has been terminated or an alternative structure is used, the mergers contemplated under the Merger Agreement will be effected as follows:

•

15 Beach, MHC will merge with and into Hometown MHC, with Hometown MHC as the surviving corporation (the “MHC Merger”);

•

Immediately following the MHC Merger, the Company will merge with and into Merger Sub, with the Company as the surviving corporation and a wholly owned subsidiary of Hometown Financial (the “Merger”);

•

Immediately following the Merger, the Company will merge with and into Hometown Financial, with Hometown Financial as the surviving corporation (the “Second Step Merger”); and

•

Immediately following the Second Step Merger, Colonial Federal will merge with and into North Shore Bank (the “Bank Merger”).

Merger Consideration

Each outstanding share of Company common stock, except for shares held by 15 Beach, MHC, Hometown Financial, or their respective subsidiaries, will be converted into the right to receive $14.25 per share at the closing of the Merger.

Company Common Stock Price

The Company’s common stock trades on the Nasdaq Capital Market under the symbol “CFSB.” During the 60-day period prior to the announcement of the Merger, our common stock closed as low as $7.40 per share and as high as $8.19 per share. On May 20, 2025, which was the last trading day before we announced the Merger, our common stock closed at $8.19 per share.

Continental Stock Transfer and Trust Company will act as paying agent for the benefit of the holders of Company common stock. Each holder of Company common stock who properly surrenders his or her Company shares to the paying agent will be entitled to receive a cash payment of $14.25 per share of Company common stock, net of any required tax withholding upon acceptance of the shares by the paying agent.

As soon as reasonably practicable after the closing of the Merger, but in no event later than five business days after the closing of the Merger, the paying agent will send a letter of transmittal that will contain detailed instructions for surrendering certificates of Company common stock. If you hold your Company common stock in “street name,” your broker, bank or nominee will process the exchange on your behalf.

You should not return your Company common stock certificates with the enclosed proxy, and you should not send your stock certificates to the paying agent until you receive the letter of transmittal.

If your Company stock certificates have been lost, stolen or destroyed, you will have to prove your ownership of these certificates and that they were lost, stolen or destroyed and, if required by the paying agent or Hometown Financial, you may have to post a bond in such amount as the paying agent may direct as indemnity against any claim that may be made against it, the Company, or another party with respect to such certificate, before you receive any payment for the shares represented by that certificate.

Neither Hometown Financial nor any other person involved in the Merger will be liable to any former holder of Company common stock for any amount properly delivered to a public official under applicable abandoned property or escheat laws.

Material Federal Income Tax Consequences of the Merger

Tax matters are complicated, and the tax consequences of the Merger depend upon the particular circumstances of each U.S. holder. Accordingly, each shareholder should seek advice with respect to the potential tax consequences based on his, her or its particular circumstances from an independent tax advisor.

The following is a general discussion of certain material United States federal income tax consequences of the Merger to U.S. holders (as defined below) of Company common stock. This discussion applies only to shareholders that hold their shares of Company common stock as a capital asset within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”). Further, this discussion does not address all aspects of United States federal taxation that may be relevant to a particular shareholder in light of its personal circumstances or to shareholders subject to special treatment under the United States federal income tax laws, including: banks or trusts; tax-exempt organizations; insurance companies; dealers in securities or foreign currency; traders in securities who elect to apply a mark-to-market method of accounting; mutual funds; S corporations or other pass-through entities and investors in such entities; foreign persons; shareholders who received their shares of Company common stock through the exercise of employee stock options, through a tax-qualified retirement plan or otherwise as compensation; shareholders who hold Company common stock as part of a hedge, straddle, constructive sale, conversion transaction or other integrated instrument; and shareholders subject to the alternative minimum tax provisions of the Code.

This discussion is based on the Code, Treasury regulations, administrative rulings and judicial decisions, all as in effect as of the date of this proxy statement and all of which are subject to change (possibly with retroactive effect) and to differing interpretations that could affect the accuracy of the statements and conclusions set forth in this discussion. Tax considerations under state, local and foreign laws are not addressed in this document.

Determining the actual tax consequences of the Merger to you may be complex. They will depend on your specific situation and on factors that are not within our control. You should consult with your own tax advisor as to the tax consequences of the Merger in your circumstances, including the applicability and effect of the alternative minimum tax and any state, local, foreign or other tax laws and of changes in those laws.

For purposes of this discussion, the term “U.S. holder” means a beneficial owner of Company common stock that is for United States federal income tax purposes (1) an individual citizen or resident of the United States, (2) a corporation organized in or under the laws of the United States or any state thereof or the District of Columbia, (3) an estate the income of which is subject to U.S. federal income taxation regardless of its source; or (4) a trust (A) the administration of which is subject to the primary supervision of a U.S. court and with respect to which one or more “United States persons” (as defined in the Code) have the authority to control all substantial decisions, or (B) that has a valid election in place under applicable Treasury Regulations to be treated as a United States person.

The United States federal income tax consequences to a partner in an entity or arrangement treated as a partnership, for United States federal income tax purposes, that holds Company common stock generally will depend on the status of the partner and the activities of the partnership. Partners in a partnership holding Company common stock should consult their own tax advisors.

Neither the Company nor Hometown Financial has requested or will request a ruling from the Internal Revenue Service as to any of the tax effects to Company shareholders of the Merger, and no opinion of counsel has been or will be rendered to Company shareholders with respect to any of the tax effects of the Merger to Company shareholders.

The receipt of the merger consideration by a U.S. holder in exchange for Company common stock pursuant to the Merger will generally be a taxable transaction for U.S. federal income tax purposes. In general, a U.S. holder of Company common stock will recognize gain or loss for federal income tax purposes equal to the difference, if any, between:

•

the per share cash merger consideration received by the U.S. holder in exchange for such Company common stock; and

•

the U.S. holder’s adjusted tax basis in such Company common stock.

Such gain or loss will be a capital gain or loss if such shares were held as capital assets by the U.S. holder at the effective time of the Merger. The gain or loss will be long-term capital gain or loss if the U.S. holder’s holding period is more than one year at the effective time of the Merger; otherwise, the capital gain or loss will be short-term. Gain or loss, as well as the holding period, will be determined separately for each block of shares (i.e., shares acquired at the same cost in a single transaction) surrendered pursuant to the Merger. Long-term capital gains of individuals are generally eligible for reduced rates of taxation. Additionally, a 3.8% Net Income Tax (or Medicare Tax) may apply to all or a portion of the gain recognized by individuals, trusts and estates whose income exceeds certain threshold levels.

Under the Code, a U.S. holder of Company common stock may be subject, under certain circumstances, to information reporting on the cash received in the Merger unless such U.S. holder is a corporation or other exempt recipient. Backup withholding will also apply (currently at a rate of 24%) with respect to the amount of cash received, unless a U.S. holder provides proof of an applicable exemption or a correct taxpayer identification number and otherwise complies with the applicable requirements of the backup withholding rules. Backup withholding is not an additional tax liability and any amount withheld under the backup withholding rules may generally be refunded or credited against a U.S. holder’s United States federal income tax liability, if any, provided that such U.S. holder furnishes the required information to the Internal Revenue Service in a timely manner.

The foregoing discussion does not claim to be a complete discussion of the potential tax consequences of the merger. Company shareholders should consult their tax advisors as to the specific tax consequences to them of the Merger, including the applicability and effect of U.S. Federal, state, local and foreign income, estate, gift and other tax laws in their circumstances. Nothing in this discussion is intended to be, or should be construed as, tax advice.

Background of the Merger

Since Colonial Federal’s reorganization into the mutual holding company form of organization and concurrent initial public offering in January 2022, the Company’s Board of Directors (the “Board of Directors” or the “Board”) and management have periodically reviewed and assessed strategic opportunities and challenges. The Board of Directors has considered the difficulty in growing while remaining profitable and operating a publicly-traded community financial institution under current economic and competitive conditions. At the same time, like many other small financial institutions, the Company has experienced increasing costs for technology, infrastructure and regulatory compliance.

On April 19, 2024, Michael E. McFarland, President and Chief Executive Officer of the Company, met with William Parent, the Chief Strategy Officer of Hometown Financial, at which the parties discussed the banking industry in general, continuing consolidations in the local banking market, and if the Company may have any interest in discussing any potential opportunities. Mr. McFarland noted the three-year prohibition on the Company engaging in negotiations with a third party, which would not expire until January 2025. The parties agreed to keep open the lines of communication.

On May 1, 2024, Mr. McFarland met with Matthew Sosik, President and Chief Executive Officer of Hometown Financial at a banking conference. Mr. Sosik let Mr. McFarland know of Hometown Financial’s

continued interest in a business combination with the Company. The parties also discussed the institutions’ complementary branch footprint and the strengths of each organization.

Also on May 1, 2024, at that same conference, Mr. McFarland met with the President and Chief Executive Officer of a Massachusetts-chartered mutual holding company (“Company A”). The executives discussed the South Shore region of Massachusetts, the local banking market and the continued consolidation of the industry. The President and CEO of Company A also indicated that his bank would be interested in further discussions if the Company was interested.

On June 5, 2024, Mr. McFarland met with the President and Chief Executive Officer of Company A at which the parties discussed aspects of the South Shore market area, including loan and deposit demand and the local real estate market.

On July 17, 2024, Mr. McFarland met with the President and Chief Executive Officer of Company A to continue discussions about the possibility of a business combination, Company A’s continued interest and the potential synergies that could be achieved.

On July 25, 2024, Mr. McFarland met with Mr. Sosik at which Mr. Sosik expressed his continued interest in a strategic relationship with the Company. The executives discussed the current interest rate environment and certain other matters impacting financial institutions. The executives also discussed the complementary fit of the two organizations.

As part of the Board of Directors’ and management’s evaluation of ways to meet the ongoing challenges facing smaller financial institutions, they regularly have considered both internal growth strategies and strategic business combinations as means of achieving economies of scale. In connection with this ongoing assessment, on August 20, 2024, at a regular meeting of the Board of Directors, the Board held an informational session with a representative of Piper Sandler. Piper Sandler is a nationally recognized investment banking firm with substantial experience advising financial institutions generally, including with respect to mergers and acquisitions. Piper Sandler acted as financial advisor to the Company in connection with its reorganization into the mutual holding company form of organization and concurrent initial public offering in January 2022. The Piper Sandler representative discussed the strategic considerations attendant with a potential future sale of the Company, the market for community bank mergers and acquisitions, potential merger or acquisition partners for the Company, the factors to consider when evaluation or comparing various potential acquirors and an overview of a potential merger process, including a comparison of the different methods of solicitations of interest and an illustrative timeline. A representative of Luse Gorman, PC (“Luse Gorman”), the Company’s legal counsel, also participated in the session and discussed with the Board its fiduciary duties in the context of a potential future strategic transaction. Mr. McFarland also updated the Board on the previous conversations he had with the representatives from Hometown Financial and Company A.

On November 15, 2024, Mr. McFarland met with the President and Chief Executive Officer of Company A to continue discussions about the possibility of a business combination, Company A’s continued interest and the strengths of the two organizations.

On November 17, 2024, Mr. McFarland met with Mr. Sosik at which Mr. Sosik expressed Hometown Financial’s continued interest in a strategic relationship with the Company.

On November 21, 2024, at a regular meeting of the Board of Directors, the Board held another informational meeting with a representative of Piper Sandler. A representative of Luse Gorman was also present, who discussed with the Board its fiduciary duties in the context of a potential future strategic transaction. The Piper Sandler representative discussed various strategic matters to be considered in connection with the potential future sale of the Company and the market for community bank mergers and acquisitions, including an analysis for comparable New England and nationwide transactions. The Board was also provided a pricing analysis assuming a range of

prices. The presentation included an overview of a potential merger process, including a comparison of the different methods of soliciting interest and a potential timeline. A list of 30 potential acquisition partners for the Company was presented (which included mutual institutions with assets from approximately $1 billion to $8 billion located in New England), as were the factors to consider when evaluation or comparing various potential acquirors. Mr. McFarland also updated the Board on the previous conversations he had with the representatives from Hometown Financial and Company A.

On January 3, 2025, Mr. McFarland met with the President and Chief Executive Officer of a Massachusetts-chartered mutual holding company (“Company B”). The executives discussed the possibility of a business combination. The parties discussed their respective organizations, employees and the local market. The parties agreed to continue the dialogue in the future.

On January 21, 2025, at a regular meeting of the Board of Directors, the Board held another informational meeting with representatives of Piper Sandler and Luse Gorman. The representative of Piper Sandler reviewed materials that had previously been distributed to the Board, which supplemented and updated the previous conversations with the Board in August and November. Mr. McFarland also updated the Board on the previous conversations he had with interested third parties. Following discussion, the Board authorized Mr. McFarland to formally engage Piper Sandler as the Company’s financial advisor and to take all steps necessary to pursue a strategic combination.

On January 23, 2025, Mr. McFarland met with the President and Chief Executive Officer of a Massachusetts-chartered mutual holding company (“Company C”) at which the parties discussed a potential business combination and the footprint of the combined organization.

On January 29, 2025, Mr. McFarland met with the President and Chief Executive Officer of a Massachusetts-chartered mutual holding company (“Company D”). The executives discussed the possibility of a business combination. The parties discussed their respective organizations, employees and the local market.

On February 7, 2025, Mr. McFarland met with the President and Chief Executive Officer of Company C. The executives discussed a potential transaction and the President and Chief Executive Officer expressed Company C’s continued interest in a transaction.

On February 12, 2025, Mr. McFarland met with the President and Chief Executive Officer of Company A at which the President and Chief Executive Officer expressed Company A’s continued interest in a transaction.

On February 14, 2025, the Company entered into a letter with Piper Sandler to engage it as the Company’s exclusive financial advisor. Following Piper Sandler’s engagement, Piper Sandler and the Company’s management began preparation of a confidential information memorandum that would be provided to each potential interested bidder.

Mr. McFarland and the Company’s legal and financial advisors discussed which institutions Piper Sandler should contact to gauge their interest in entering into a business combination with the Company. The discussions balanced the need to conduct a process designed to maximize the value to be received by shareholders without being so expansive to risk the confidential nature of the process. Mr. McFarland and his advisors discussed which institutions had sufficient capital to undertake the transaction, had expressed interest to the Company or in undertaking M&A in general and were a good cultural and geographic fit. Based on such conversations, Piper Sandler was authorized to reach out to six institutions – the five that had previously contacted Mr. McFarland and one other Massachusetts-chartered mutual holding company.

On February 18, 2025, at a regular meeting of the Board of Directors, the Board held another informational meeting with representatives of Piper Sandler and Luse Gorman. The representative of Piper Sandler reviewed the likely solicitation process, including the materials that would be prepared to allow parties to make an informed bid. A representative from Luse Gorman reminded the Board of the continued importance of

confidentiality and discussed how that would be maintained throughout the solicitation and diligence process. Mr. McFarland also updated the Board on the previous conversations he had with interested third parties since the date of the last Board meeting.

Beginning on March 6, 2025, Piper Sandler, on behalf of the Company, contacted the six institutions to confirm they remained interested in a possible business combination. The Company’s identity was not disclosed to these parties at that time. Of the parties contacted, each executed non-disclosure agreements between March 6, 2025 and March 17, 2025. None of the non-disclosure agreements contained a standstill provision precluding such party from submitting a topping bid directly to the Board of Directors. Following execution of the non-disclosure agreements, each of the parties were informed of the Company’s identity and was provided a copy of a confidential information memorandum and access to a virtual data room with certain initial diligence materials. The confidential information memorandum provided detailed instructions as to the contents that any indications of interest should contain and requested that all such indications be received no later than April 2, 2025.

On March 18, 2025, at a regular meeting of the Board of Directors, the Board held another informational meeting with representatives of Piper Sandler and Luse Gorman. The Board was updated on the solicitation process.

On April 2, 2025, each of Hometown and Companies A, B, C, D submitted written non-binding indications of interest to acquire the Company in an all-cash transaction. The prices of the offers ranged from a low of $12.00 per share to a high of $14.00 per share. The indications of interest each shared the respective bidder’s financial assumptions and included its offers on other matters, including board seats, employee matters (including severance) and timing.

On April 8, 2025, a special meeting of the Board of Directors of the Company was held to review the various indications of interest. Representatives of Piper Sandler and Luse Gorman also participated in the meeting. A representative from Piper Sandler discussed its presentation materials, a copy of which had been previously provided to the Board of Directors, which provided a side-by-side comparison of the five indications of interest that had been submitted. The representative from Piper Sandler noted that subsequent to receipt of the indications of interest, he spoke with representatives of each of the bidding companies to gain any additional guidance that may not have been included in the written submissions. The presentation also included a summary of the pricing of four New England transactions announced since 2024 as well as all nationwide bank transactions with a value over $15 million over the same time period. A potential timeline for the merger transaction was discussed. Additionally, an overview of each of the bidders, including historical information, the pro forma branch footprint and pro forma loan and deposit composition was discussed as a part of the presentation materials.

The Board considered that Hometown Financial was the highest bidder and $0.50 per share higher than the upper range provided by the second highest bidder and $0.90 per share higher than the third highest bidder. Mr. McFarland shared his thoughts about the various parties based on his previous interactions with each of them. The Board also recognized Hometown Financial’s history of successfully executing and integrating other financial institutions and that its banking subsidiary and Colonial Federal shared the same data service provider, which would facilitate integration. The Board and its legal and financial advisor considered whether to invite a reduced list of parties to conduct further diligence and submit revised offers. However, the Board weighed the likelihood that such a process would result in higher bids and its desire to move expeditiously towards a definitive agreement.

After deliberation, the Board determined that it would request Piper Sandler to contact Hometown Financial to request that it increase its price to $14.25 per share. The Board further voted, that if Hometown agreed to do so, the Company would: (1) proceed with the negotiation with Hometown Financial of a definitive agreement substantially consistent with the terms outlined in the Hometown Financial indication of interest letter for

presentation to and consideration by the Board of Directors at the earliest practicable date; (2) take all necessary and appropriate action on behalf of the Company toward such end, including, in consultation with the Company’s legal and financial advisors, conducting a due diligence investigation of Hometown Financial; and (3) allow Hometown Financial to continue to conduct its due diligence investigation of the Company.

On April 8, 2025, the representative of Piper Sandler contacted Hometown Financial with the Board’s request and Hometown Financial submitted a revised indication of interest with a price of $14.25 per share, which the Company countersigned the same day. The revised indication of interest contained a provision whereby the Company agreed to negotiate exclusively with Hometown Financial for a period of 45 days from the date of the indication of interest.

In April 2025, a data room containing diligence materials requested by Hometown Financial relating to the Company was made available to Hometown Financial management and its legal and financial advisors.

On April 21, 2025, representatives from Hometown conducted its on-site review of the Colonial Federal loan portfolio.

During April and May 2025, representatives of the management teams of Hometown Financial and the Company talked several times to discuss the Merger, the operations and business of the two companies and certain logistical issues.

On May 2, 2025, Luse Gorman provided Kilpatrick Townsend & Stockton, LLP (“Kilpatrick Townsend”), legal counsel for Hometown Financial with a draft of the Merger Agreement. Continuing through the date of execution, the parties, along with their legal counsel and financial advisors, continued to review and negotiate the Merger Agreement, along with various other ancillary documents.

A representative of Piper Sandler made a presentation, a copy of which had been sent in advance to the directors.

The Piper Sandler representative began by summarizing the process to date. He presented several key transaction multiples and compared the stock price performance of the Company against certain stock indices and indicated the trading volume of the Company’s stock over various periods during the past year. The Piper Sandler representative compared the financial metrics for this transaction against the financial metrics of transactions for certain selected peer groups. He also summarized the results of a discounted cash flow analysis Piper Sandler performed on the Company. He concluded his presentation by rendering Piper Sandler’s opinion, to the effect that, as of May 20, 2025 and subject to the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Piper Sandler as set forth in Piper Sandler’s opinion, the consideration to be received by the holders of the Company’s common stock (other than 15 Beach, MHC) was fair, from a financial point of view, to such shareholders.

Following these presentations and discussions among the members of the Board of Directors, including consideration of the factors described under “—The Company’s Reasons for the Merger,” the Board of Directors determined that the Merger Agreement and the transactions contemplated thereby, including the merger of the Company and Hometown Financial, were advisable and in the best interests of the Company and its shareholders, and the directors unanimously voted to adopt the Merger Agreement and the transactions contemplated thereby, and recommended that the Company’s shareholders approve the Merger Agreement and the merger.

The Company’s Reasons for the Merger

The discussion of the information and factors considered by the Company’s board of directors is not intended to be exhaustive, but rather includes the principal material information, factors and analyses considered by the Board in reaching its conclusions and recommendation in relation to the Merger Agreement and the transactions. The Board evaluated the Merger Agreement and the transactions in consultation with Colonial’s executive management and the Company’s outside legal and financial advisors. The Board did not provide a specific assessment of, quantify or otherwise assign any relative weights to, the factors considered in determining its recommendation. Instead, the Board conducted an overall analysis of the factors and reasons described above and determined in its business judgment that, in the aggregate, the potential benefits of the Merger to the shareholders of the Company outweighed the risks or potential negative consequences. Individual members of the Board may have given different weight to different factors. In addition, in arriving at its recommendation, the directors of the Company were aware of the interests of certain officers and directors of the Company as described under “Interests of Directors and Officers in the Merger that are Different From Your Interests.”

In evaluating and reaching its decision to approve the Merger Agreement and recommend that the Company’s shareholders approve the Merger Agreement, the Company’s board of directors considered a number of factors, including the following, which are not intended to be exhaustive and are not presented in any relative order of importance:

•

the belief of the board of directors that the merger consideration of $14.25 per share in cash represents fair value for shares of Company common stock, taking into account Colonial’s current and historical financial condition, results of operations, business, competitive position and prospects, particularly in comparison to Colonial’s near-term and long-term standalone plans if the Company were to remain an independent company, and the future prospects and risks associated with remaining an independent company and the risks and uncertainties associated with the execution of the standalone plan;

•

the opportunity for the Company’s shareholders to realize substantial value based on the merger consideration offered by Hometown Financial, which represents 1.23x of the Company’s tangible book value per share and an 82.5% premium over the one day prior Company common stock trading price;

•

that the merger consideration consists solely of cash, which provides certainty of value and liquidity to the shareholders of the Company and does not expose them to any future risks related to the business or the financial markets generally as compared to remaining an independent, standalone company;

•

the merger consideration offered by Hometown Financial equaled or exceeded the consideration that was presented by other parties throughout the process and that could reasonably be expected from other potential acquirers with the apparent ability to consummate the acquisition of Colonial, taking into consideration all factors;

•

pricing and other considerations for other recent financial institution acquisition transactions;

•

the understanding of the Company’s board of directors of the strategic options available to Colonial and the board of directors’ assessment of those options with respect to the prospects and estimated results of the execution by the Company of its business plan as an independent entity under various scenarios and the determination that none of those options or the execution of the business plan were more likely to create greater present value for the Company’s shareholders than the value to be paid by Hometown Financial;

•

the current and prospective environment in the financial services industry, including economic conditions and the interest rate and regulatory environments, the accelerating pace of technological change in the financial services industry, operating costs resulting from regulatory and compliance mandates, scale and marketing expenses, increasing competition from both banks and non-bank financial and financial technology firms, current financial market conditions, current employment market conditions and the likely effects of these factors on Colonial Federal’s potential growth, development, productivity and strategic options;

•

the historical stock market performance for the Company’s common stock and the common stock performance of other publicly-traded issuers in the banking industry;

•

the Company board of directors’ views with respect to other potential strategic alternatives, including remaining independent, making acquisitions, pursuing other similarly-sized merger partners, pursuing larger merger partners and undertaking a second-step conversion transaction whereby 15 Beach, MHC would convert from a mutual holding company form of structure to a stock holding company form of structure;

•

the ability of Hometown Financial to execute a merger transaction from a financial and regulatory perspective, especially in light of the fact that Hometown Financial was a seasoned acquiror;

•

that Hometown Financial has integration experience through various acquisitions, which could be beneficial to the integration process;

•

the geographic fit and increased customer convenience of the expanded branch network of Hometown Financial;

•

the benefits to Colonial Federal and its customers of operating as a significantly larger organization, the wider array of financial products and services that would be available to customers of Colonial Federal and the communities served by Colonial Federal, including enhancements in technology investments, products and services, the ability to grow its lending portfolio, higher lending limits that would enable Colonial Federal to serve customers whose lending relationships were approaching Colonial Federal’s legal lending limit, and greater financial resources;

•

Hometown Financial’s current form of organization, including that Hometown Financial is in the mutual holding company form of corporate organization and that the members/customers of Colonial Federal will have the benefit of mutual interests, and membership rights, in Hometown Financial’s mutual holding company following the transaction;

•

Hometown Financial’s business, operations, financial condition, asset quality, earnings and prospects, taking into account the results of the Company’s due diligence review of Hometown Financial, and information provided by Hometown Financial’s financial advisor;

•

the complementary nature of the cultures and operational philosophies of the two companies, including with respect to their community banking business model, strategic focus, target markets, client service, credit cultures, risk profiles and community commitment, and the Company’s board of director’s belief that the complementary cultures will facilitate the successful integration and implementation of the transaction;

•

the financial presentation, dated May 20, 2025, of Piper Sandler to the Company’s board of directors and the opinion, dated May 20, 2025, of Piper Sandler to the Company’s board of directors as to the fairness, from a financial point of view and as of the date of the opinion, of the merger consideration to be received by the holders of the Company’s common stock (other than 15 Beach, MHC) in the Merger to such holders, as more fully described below under “ — Opinion of the Company’s Financial Advisor”;

•

the terms of the Merger Agreement, including the representations and warranties of the parties, the covenants, the consideration, the circumstances under which the Company’s board of directors may consider a superior proposal and the circumstances upon which the Company’s board of directors may terminate the Merger Agreement;

•

the review by the Company’s board of directors, with legal counsel, of the material terms of the Merger Agreement, including (1) the Board’s ability, under certain circumstances, to consider an unsolicited acquisition proposal, (2) the Board’s ability to terminate the Merger Agreement to enter into a definitive agreement with respect to a superior proposal (subject to payment of a $1,550,000 termination fee), (3) the Board’s ability to terminate the Merger Agreement if a regulatory approval

necessary to consummate the Merger was not received solely as result of Hometown Financial’s regulatory condition, and (4) the nature of the covenants, representations and warranties and other termination provisions in the Merger Agreement;

•

the effects of the Merger on Colonial Federal employees, including the prospects for continued employment in a larger organization, and Hometown Financial’s commitment to provide Colonial Federal employees with aggregate annual base salary or wages at least equal to their aggregate salary or wages prior to the effective time;

•

that Colonial Federal employees would receive severance benefits if they are separated from Hometown Financial, other than for cause, at any time up to and for a period of nine months following the consummation of the Merger;

•

the ability of Colonial Federal employees to participate in the employee benefit plans of Hometown Financial following the consummation of the transaction;

•

the likelihood of expeditiously obtaining the regulatory approvals necessary to complete the transaction without unusual or burdensome conditions;

•

the uncertainty surrounding potential legal, regulatory and policy changes that may directly affect financial institutions and the global economy; and

•

the increasing importance of operational scale and financial resources in maintaining efficiency and remaining competitive over the long term and in being able to capitalize on technological developments that significantly impact industry competitive conditions.

The Company’s board of directors also considered a number of potential risks and uncertainties associated with the Merger during its deliberation of the proposed transaction, including, without limitation, the following:

•

the potential risk of diverting management and employee attention and resources from the operation of Colonial Federal’s business and towards the completion of the Merger;

•

that the Merger Agreement restricts the conduct of Colonial Federal’s business before the completion of the Merger that, subject to specific exceptions, could delay or prevent Colonial Federal from undertaking business opportunities that may arise or any other action it would otherwise take with respect to the operations of Colonial absent the pending Merger;

•

that, while Colonial expects that the Merger will be consummated, there can be no assurance that all conditions to the parties’ obligations to complete the Merger Agreement will be satisfied, including the risk that necessary regulatory approvals or the Company’s shareholder approval (or member approval, if required) might not be obtained and, as a result, the Merger may not be consummated;

•

the risk of potential employee attrition and/or adverse effects on business and customer relationships as a result of the pending Merger;

•

certain anticipated Merger-related costs;

•

that: (1) the Company would be prohibited from affirmatively soliciting acquisition proposals after execution of the Merger Agreement; and (2) the Company would be obligated to pay to Hometown Financial a termination fee of $1,550,000 if the Merger Agreement is terminated under certain circumstances, which may discourage other parties potentially interested in a business combination with Colonial from pursuing such a transaction;

•

that the board of directors is required to submit the Merger to the vote of the Company’s shareholders at the special meeting even if the Board has made a change of recommendation, unless the amended Merger Agreement is terminated;

•

the possibility of litigation in connection with the transaction; and

•

that the gain likely to be realized by the Company’s shareholders as a result of the Merger generally will be taxable to such shareholders for U.S. federal income tax purposes if they are not otherwise exempt from the payment of such taxes.

The Company’s board of directors unanimously recommends that the Company’s shareholders vote “FOR” the adoption of the merger proposal, and “FOR” the Adjournment Proposal.

The Company’s shareholders should be aware that some members of Colonial’s board of directors and executive officers may have interests in the Merger that are different from, or in addition to, those of other Company shareholders. The Company’s board of directors was aware of and considered these interests, among other matters, in evaluating and negotiating the Merger Agreement, and in recommending that the merger proposal be approved by the shareholders of the Company. See “Interests of Directors and Officers in the Merger that are Different From Your Interests.”

This summary of the reasoning of the Company’s board of directors and other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading “Cautionary Note Regarding Forward-Looking Statements.”

Opinion of the Company’s Financial Advisor

The Company retained Piper Sandler to act as financial advisor to the Company’s board of directors in connection with the Company’s consideration of a possible business combination. The Company selected Piper Sandler to act as its financial advisor because Piper Sandler is a nationally recognized investment banking firm that specializes in the representation of financial institutions. In the ordinary course of its investment banking business, Piper Sandler is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

Piper Sandler acted as financial advisor to the Company’s board of directors in connection with the proposed merger and participated in certain of the negotiations leading to the execution of the Merger Agreement. At the May 20, 2025 meeting at which the Company’s board of directors considered the Merger and the Merger Agreement, Piper Sandler delivered to the board of directors its oral opinion, which was subsequently confirmed in writing on May 20, 2025, to the effect that, as of such date, the merger consideration was fair, from a financial point of view, to the holders of the Company’s common stock (other than 15 Beach, MHC). The full text of Piper Sandler’s opinion is attached as Annex B to this proxy statement. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Piper Sandler in rendering its opinion. The description of the opinion set forth below is qualified in its entirety by reference to the full text of the opinion. Holders of the Company’s common stock are urged to read the entire opinion carefully in connection with their consideration of the proposed merger.

Piper Sandler’s opinion was directed to the board of directors of the Company in connection with its consideration of the Merger Agreement and the Merger and does not constitute a recommendation to any shareholder of the Company as to how any such shareholder should vote at any meeting of shareholders called to consider and vote on the approval of the Merger Agreement and the Merger. Piper Sandler’s opinion was directed only to the fairness, from a financial point of view, of the merger consideration to the holders of the Company’s common stock (other than 15 Beach, MHC) and did not address the underlying business decision of the Company to engage in the Merger, the form or structure of the Merger or any other transactions contemplated in the Merger Agreement, the relative merits of the Merger as compared to any other alternative transactions or business strategies that might exist for the Company, or the effect of any other transaction in which the Company might engage. Piper Sandler also did not express any opinion as to the fairness of the amount or nature of the compensation to be received in the Merger by any officer, director or employee of the Company or Hometown MHC, or any class of such persons, if any, relative to the compensation to be received in the merger by any other shareholder. Piper Sandler’s opinion was approved by Piper Sandler’s fairness opinion committee.

In connection with its opinion, Piper Sandler reviewed and considered, among other things:

•

a draft of the Merger Agreement dated May 14, 2025;

•

certain publicly available financial statements and other historical financial information of the Company that Piper Sandler deemed relevant;

•

certain publicly available financial statements and other historical financial information of Hometown MHC and Hometown Financial that Piper Sandler deemed relevant;

•

certain internal financial projections for the Company for the fiscal years ending June 30, 2025 through June 30, 2029, as provided by the senior management of the Company;

•

the pro forma financial impact of the merger on Hometown MHC’s regulatory capital ratios following the closing date given certain assumptions relating to purchase accounting adjustments and estimated transaction costs, as provided by the senior management of Hometown MHC;

•

a comparison of certain financial and market information for the Company with similar banks and thrifts for which information was publicly available;

•

the current market environment generally and the banking environment in particular; and

•

such other information, financial studies, analyses and investigations and financial, economic and market criteria as Piper Sandler considered relevant.

Piper Sandler also discussed with certain members of the senior management of the Company the business, financial condition, results of operations and prospects of the Company and held similar discussions with certain members of the senior management of Hometown MHC and its representatives regarding the business, financial condition, results of operations and prospects of Hometown MHC.

In performing its review, Piper Sandler relied upon the accuracy and completeness of all the financial and other information that was available to and reviewed by Piper Sandler from public sources, that was provided to Piper Sandler by the Company or Hometown MHC or their respective representatives, or that was otherwise reviewed by Piper Sandler, and Piper Sandler assumed such accuracy and completeness for purposes of rendering its opinion without any independent verification or investigation. Piper Sandler relied on the assurances of the respective managements of the Company and Hometown MHC that they were not aware of any facts or circumstances that would have made any of such information inaccurate or misleading. Piper Sandler was not asked to and did not undertake an independent verification of any of such information and Piper Sandler did not assume any responsibility or liability for the accuracy or completeness thereof. Piper Sandler did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of the Company or Hometown MHC, nor was Piper Sandler furnished with any such evaluations or appraisals. Piper Sandler rendered no opinion or evaluation on the collectability of any assets or the future performance of any loans of the Company or Hometown MHC. Piper Sandler did not make an independent evaluation of the adequacy of the allowance for credit losses of the Company or Hometown MHC, or of the combined entity after the merger, and Piper Sandler did not review any individual credit files relating to the Company or Hometown MHC or any of their respective subsidiaries. Piper Sandler assumed, with the Company’s consent, that the respective allowances for credit losses for both the Company and Hometown MHC were adequate to cover such losses and would be adequate on a pro forma basis for the combined entity.

In preparing its analyses, Piper Sandler used certain internal financial projections and estimates for the Company for the fiscal years ending June 30, 2025 through June 30, 2029, as provided by the senior management of the Company. Piper Sandler also received and used in its pro forma analyses certain assumptions relating to purchase accounting adjustments and estimated transaction costs, as provided by the senior management of Hometown MHC. With respect to the foregoing information, the senior management of the Company confirmed to Piper Sandler that such information reflected the best currently available projections and estimates of senior management as to the future financial performance of the Company, and the senior management of Hometown

MHC confirmed to Piper Sandler that such assumptions reflected the best currently available estimates of senior management with respect to the pro forma impact of the Merger on Hometown MHC’s regulatory capital ratios following the Merger, and Piper Sandler assumed, in each case, that such performance would be achieved. Piper Sandler expressed no opinion as to such information, or the assumptions on which such information was based. Piper Sandler also assumed that there had been no material change in the respective assets, financial condition, results of operations, business or prospects of the Company or Hometown MHC since the date of the most recent financial statements made available to Piper Sandler. Piper Sandler assumed in all respects material to its analyses that the Company and Hometown MHC would remain as going concerns for all periods relevant to its analyses.

Piper Sandler also assumed, with the Company’s consent, that (1) each of the parties to the Merger Agreement would comply in all material respects with all material terms and conditions of the Merger Agreement and all related agreements, that all of the representations and warranties contained in such agreements were true and correct in all material respects, that each of the parties to such agreements would perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements were not and would not be waived, (2) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the Merger, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on the Company, Hometown MHC, the Merger or any related transactions, and (3) the Merger and any related transactions would be consummated in accordance with the terms of the Merger Agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements. Finally, with the Company’s consent, Piper Sandler relied upon the advice that the Company received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the Merger and the other transactions contemplated by the Merger Agreement. Piper Sandler expressed no opinion as to any such matters.

Piper Sandler’s opinion was necessarily based on financial, economic, regulatory, market and other conditions as in effect on, and the information made available to Piper Sandler as of, the date thereof. Events occurring after the date thereof could materially affect Piper Sandler’s opinion. Piper Sandler has not undertaken to update, revise, reaffirm or withdraw its opinion or otherwise comment upon events occurring after the date thereof. Piper Sandler did not express any opinion as to the trading value of the Company common stock at any time.

In rendering its opinion, Piper Sandler performed a variety of financial analyses. The summary below is not a complete description of all the analyses underlying Piper Sandler’s opinion or the presentation made by Piper Sandler to the Company’s board of directors, but is a summary of the material analyses performed and presented by Piper Sandler. The summary includes information presented in tabular format. To fully understand the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Piper Sandler believes that its analyses must be considered as a whole and that selecting portions of the factors and analyses to be considered without considering all factors and analyses, or attempting to ascribe relative weights to some or all such factors and analyses, could create an incomplete view of the evaluation process underlying its opinion. Also, no company included in Piper Sandler’s comparative company analyses described below is identical to the Company or Hometown MHC and no transaction is identical to the Merger. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or transaction values, as the case may be, of the Company and Hometown MHC and the companies to which they were compared. In arriving at its opinion, Piper Sandler did not attribute any particular weight to any analysis or factor that it considered. Rather, Piper Sandler made qualitative judgments as to the significance and relevance of each analysis and factor. Piper

Sandler did not form an opinion as to whether any individual analysis or factor (positive or negative) considered in isolation supported or failed to support its opinion, rather, Piper Sandler made its determination as to the fairness of the merger consideration to the holders of the Company’s common stock (other than 15 Beach, MHC) on the basis of its experience and professional judgment after considering the results of all its analyses taken as a whole.

In performing its analyses, Piper Sandler also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which cannot be predicted and are beyond the control of the Company, Hometown MHC, and Piper Sandler. The analyses performed by Piper Sandler are not necessarily indicative of actual values or future results, both of which may be significantly more or less favorable than suggested by such analyses. Piper Sandler prepared its analyses solely to render its opinion and provided such analyses to the Company’s board of directors at its May 20, 2025 meeting. Estimates on the values of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may be sold. Such estimates are inherently subject to uncertainty and actual values may be materially different. Accordingly, Piper Sandler’s analyses do not necessarily reflect the value of the Company common stock or the prices at which the Company common stock may be sold at any time. The analyses of Piper Sandler and its opinion were among a number of factors taken into consideration by the Company’s board of directors in making its determination to approve the Merger Agreement and the analyses described below should not be viewed as determinative of the decision of the Company’s board of directors with respect to the fairness of the merger consideration to the to the holders of Company common stock (other than 15 Beach, MHC).

Summary of Proposed Merger Consideration and Implied Transaction Metrics.

Piper Sandler reviewed the financial terms of the proposed Merger. Pursuant to the terms of the Merger Agreement, at the effective time of the Merger each share of the Company’s common stock issued and outstanding immediately prior to the effective time of the transaction, except for certain shares as set forth in the Merger Agreement, shall be converted into the right to receive $14.25 in cash, without interest. Piper Sandler calculated an aggregate implied transaction value of approximately $43.8 million. Based upon financial information for the Company as of or for the last twelve months (“LTM”) ended March 31, 2025, and the closing price of the Company’s common stock on May 16, 2025, Piper Sandler calculated the following implied transaction metrics:


Transaction Price Per Share / Stated Book Value Per Share	123	%
Transaction Price Per Share / Stated Tangible Book Value Per Share	123	%
Tangible Book Premium / Core Deposits (CDs > 100k)⁽¹⁾	1.2	%
Tangible Book Premium / Core Deposits (CDs > 250k)⁽²⁾	1.1	%
Premium to the Company’s Stock price as of May 16, 2025	82	%

(1)	Core deposits equal to total deposits less CDs greater than $100,000

(2)	Core deposits equal to total deposits less CDs greater than $250,000

Analysis of Precedent Transactions.

Piper Sandler reviewed a nationwide group of recent merger and acquisition transactions. The nationwide group consisted of bank and thrift merger and acquisition transactions announced between January 1, 2023 and May 16, 2025 with target total assets between $100 million and $950 million and LTM ROAA less than 0.35% (the “Nationwide Precedent Transactions”).

The Nationwide Precedent Transactions group was composed of the following transactions:


Acquiror		Target
Plumas Bancorp		Cornerstone Community Bancorp
Mid Penn Bancorp Inc.		William Penn Bancorp
Mifflinburg Bancorp Inc.		Northumberland Bancorp
TowneBank		Village Bank and Trust Financial Corp.
ESL FCU		Generations Bancorp NY, Inc.
First National Corp.		Touchstone Bankshares
National Bankshares Inc.		Frontier Community Bank
Princeton Bancorp		First National B&TC
LCNB Corp.		Eagle Financial Bancorp Inc
NexTier Inc.		Mars Bancorp Inc.

Using the latest publicly available information prior to the announcement of the relevant transaction, Piper Sandler reviewed the following transaction metrics: transaction price to LTM earnings per share, transaction price to tangible book value per share, core deposit premium, and one-day market premium. Piper Sandler compared

the indicated transaction metrics for the Merger to the median, mean, low and high metrics of the Nationwide Precedent Transactions group.

Net Present Value Analyses.

Piper Sandler performed an analysis that estimated the net present value of a share of the Company’s common stock assuming the Company performed in accordance with internal financial projections and estimates for the Company for the fiscal years ending June 30, 2025 through June 30, 2029, as provided by the senior management of the Company. To approximate the terminal value of a share of the Company’s common stock at May 20, 2025, Piper Sandler applied price to 2029 earnings multiples ranging from 14.0x to 24.0x and multiples of 2029 tangible book value ranging from 60% to 110%. The terminal values were then discounted to present values using different discount rates ranging from 10.0% to 14.0%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of the Company’s common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of the Company common stock of $2.00 to $4.00 when applying multiples of earnings and $4.26 to $9.09 when applying multiples of tangible book value.

Earnings Per Share Multiples


Discount Rate	14.0x	16.0x	18.0x	20.0x	22.0x	24.0x
10.0%	$2.33	$2.66	$3.00	$3.33	$3.66	$4.00
11.0%	$2.24	$2.56	$2.88	$3.20	$3.53	$3.85
12.0%	$2.16	$2.47	$2.78	$3.09	$3.39	$3.70
13.0%	$2.08	$2.38	$2.67	$2.97	$3.27	$3.56
14.0%	$2.00	$2.29	$2.58	$2.86	$3.15	$3.43

Tangible Book Value Per Share Multiples


Discount Rate	60%	70%	80%	90%	100%	110%
10.0%	$4.96	$5.78	$6.61	$7.44	$8.26	$9.09
11.0%	$4.77	$5.57	$6.36	$7.16	$7.95	$8.75
12.0%	$4.59	$5.36	$6.12	$6.89	$7.65	$8.42
13.0%	$4.42	$5.16	$5.90	$6.63	$7.37	$8.11
14.0%	$4.26	$4.97	$5.68	$6.39	$7.10	$7.81

Piper Sandler also considered and discussed with the Company’s board of directors how this analysis would be affected by changes in the underlying assumptions, including variations with respect to earnings. To illustrate this impact, Piper Sandler performed a similar analysis, assuming the Company’s earnings varied from 20.0% above projections to 20% below projections. This analysis resulted in the following range of per share values for the Company’s common stock, applying the price to 2029 earnings multiples range of 14.0x to 24.0x referred to above and a discount rate of 11.58%.

Earnings Per Share Multiples


Annual Estimate Variance	14.0x	16.0x	18.0x	20.0x	22.0x	24.0x
(20%)	$1.76	$2.01	$2.26	$2.51	$2.76	$3.01
(10%)	$1.97	$2.26	$2.54	$2.82	$3.10	$3.39
0.0%	$2.19	$2.51	$2.82	$3.13	$3.45	$3.76
10%	$2.41	$2.76	$3.10	$3.45	$3.79	$4.14
20%	$2.63	$3.01	$3.39	$3.76	$4.14	$4.51

Piper Sandler noted that the net present value analysis is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, and the results thereof are not necessarily indicative of actual values or future results.

Pro Forma Results and Capital Ratios.

Piper Sandler analyzed certain potential pro forma effects of the Merger on Hometown MHC’s capital ratios given certain assumptions relating to purchase accounting adjustments and estimated transaction costs. The analysis indicated that as of May 20, 2025, Hometown MHC would maintain its regulatory capital ratios in excess of the regulatory guidelines for “well-capitalized” status following the merger. In connection with its pro forma analysis, Piper Sandler considered and discussed with the Company’s board of directors how the results thereof are not necessarily indicative of actual values or future results. The actual results achieved by the combined company may vary from projected results and the variations may be material.

Piper Sandler’s Relationship.

Piper Sandler is acting as the Company’s financial advisor in connection with the Merger and will receive a fee for such services, which fee is contingent upon consummation of the Merger. At the time of announcement of the transaction Piper Sandler’s fee was approximately $1.2 million. Piper Sandler also received a $100,000 fee from the Company upon rendering its opinion, which opinion fee will be credited in full towards the advisory fee which will become payable to Piper Sandler upon closing of the Merger. The Company has also agreed to indemnify Piper Sandler against certain claims and liabilities arising out of Piper Sandler’s engagement and to reimburse Piper Sandler for certain of its out-of-pocket expenses incurred in connection with Piper Sandler’s engagement.

Piper Sandler did not provide any other investment banking services to the Company in the two years preceding the date of its opinion. In the two years preceding the date thereof, Piper Sandler provided certain investment banking services to Hometown MHC and Hometown Financial. In summary, Piper Sandler acted as placement agent in connection with the offer and sale of Hometown Financial Senior Notes, which closed in March 2024 and for which Piper Sandler received approximately $2.3 million in compensation. In addition, in the ordinary course of Piper Sandler’s business as a broker-dealer, Piper Sandler may purchase securities from and sell securities to the Company and Hometown MHC.

Interests of Directors and Officers in the Merger that are Different From Your Interests

Some members of the Company’s management and board of directors may have interests in the Merger that are different from or in addition to the interests of shareholders. The Company’s board of directors were aware of these interests and considered them in approving the Merger Agreement. Included below is a summary of those interests.

Employment and Settlement Agreements. Colonial Federal is a party to employment agreements with change in control provisions with Mr. McFarland and Ms. Shea, which provide that if within two years after a change in control (as defined therein), the executive is involuntarily terminated, the executive will be entitled to a payment equal to three times the average of the amount reported in Box 5 of the executive’s Form W-2 plus (1) the executive’s share of non-taxable premiums paid for medical and dental insurance and (2) deductions taken from the executive’s compensation to fund the executive’s flexible spending account, for the five calendar years preceding the year of the executive’s termination of employment or preceding the year in which the change in control occurs, whichever is greater. In addition, the executive will continue to participate in benefit plans that provide medical, dental and life insurance until the earlier of (1) the executive’s death, (2) the executive’s employment by another employer or (3) 36 months after the executive’s termination of employment.

Simultaneously with the signing of the Merger Agreement, each of Mr. McFarland and Ms. Shea entered into settlement agreements with Colonial, which will provide for cash payments to be made to the executives at the closing of the Merger in exchange for the termination of their employment agreements with Colonial. The cash payments to be paid under the settlement agreements are $886,190 for Mr. McFarland and $690,000 for Ms. Shea, and are conditioned on the Merger becoming effective.

Restrictive Covenant Agreement with Michael E. McFarland. Simultaneously with the signing of the Merger Agreement, Hometown Financial, North Shore Bank and Michael E. McFarland, President and Chief Executive Officer of Colonial, entered into a Restrictive Covenant Agreement, which is conditioned on the Merger becoming effective, that provides for a cash payment of $165,000 to Mr. McFarland. Under this Restrictive Covenant Agreement, for the twelve-month period following the closing of the Merger, Mr. McFarland will be subject to certain non-solicitation and non-compete restrictions. Mr. McFarland will also be subject to confidentiality and non-disparagement obligations.

Consulting Agreement with Susan J. Shea. Simultaneously with the signing of the Merger Agreement, Hometown Financial, North Shore Bank and Susan J. Shea, Chief Operating Officer and Treasurer of Colonial, entered into a consulting agreement, which is conditioned on the Merger becoming effective. The consulting agreement provides for a consulting fee of $20,000 per month for eight months following the closing of the Merger unless Ms. Shea provides 30 days written notice to terminate the agreement.

Board Seat with North Shore Bank. North Shore Bank will consider increasing the size of its board of directors and appointing one or more interested members of the Company’s board of directors, but North Share Bank is under no obligation to do so. The remaining directors of Hometown Financial and North Shore Bank will be persons who served as directors of Hometown Financial and North Shore Bank prior to the completion of the Merger.

Protection of Company Directors and Officers Against Claims. Hometown MHC, Hometown Financial and North Shore Bank agreed to indemnify and hold harmless each current and former director, officer or employee of Colonial for six years after the Merger’s effective time for claims arising from their position with Colonial or their service to Colonial, to the fullest extent set forth in the Company’s charter and bylaws on the date of the Merger Agreement and to the fullest extent permitted under applicable law. Hometown Financial will also maintain a policy of directors’ and officers’ liability insurance coverage for the benefit of the Company’s directors and officers for six years following consummation of the Merger, subject to certain limitations on the amount of premiums to be paid.

Stock Options. Under the terms of the Merger Agreement, outstanding stock options to purchase shares of Company Common Stock, whether vested or unvested, will be cancelled and converted into the right to receive a cash payment equal to the excess of $14.25 over the exercise price per option multiplied by the number of stock options held, less applicable taxes required to be withheld. Set forth below is the number of outstanding stock options held by each director and named executive officer of the Company as of [Record Date] and the cash-out value (pre-tax) of the stock options as determined under the terms of the Merger Agreement.


Name	Exercise Price		Stock Options		Cash-Out Value (pre-tax)
Paul N. Baharian	$	9.09		14,000	$	72,240
Kemal Denizkurt	$	7.99		14,000	$	87,640
Robert Guarnieri	$	9.09		14,000	$	72,240
Edward J. Keohane	$	9.09		14,000	$	72,240
Stephen D. Marini	$	9.09		14,000	$	72,240
Michael E. McFarland	$	7.99		64,000	$	400,640
James M. O’Leary, Jr.	$	9.09		14,000	$	72,240
Susan J. Shea	$	7.99		48,000	$	300,480
Tracy Wilson	$	9.09		14,000	$	72,240

Restricted Stock Awards. Under the terms of the Merger Agreement, any vesting restrictions on the Company’s restricted stock awards that have not yet vested will lapse and such awards will be exchanged for the merger consideration, less applicable taxes required to be withheld. The number of unvested restricted stock awards as of [Record Date] that will become vested as a result of the Merger held by the named executive officers and directors of the Company, are as follows:


Name	Unvested Restricted Stock		Cash-Out Value (pre-tax)
Paul N. Baharian		3,600	$	51,300
Kemal Denizkurt		3,600	$	51,300
Robert Guarnieri		3,600	$	51,300
Edward J. Keohane		3,600	$	51,300
Stephen D. Marini		3,600	$	51,300
Michael E. McFarland		14,400	$	205,200
James M. O’Leary, Jr.		3,600	$	51,300
Susan J. Shea		10,800	$	153,900
Tracy Wilson		3,600	$	51,300

Change in Control Agreements. Colonial Federal is a party to change in control agreements with certain executives, including Kemal A. Denizkurt, the Vice President of Financial Markets, which provides that if, within 24 months after the effective date of a change in control (as defined in the change in control agreements) of the Company or Colonial Federal, the executive’s employment is involuntarily terminated, the executive will be entitled to a payment equal to two times the amount reported in Box 5 of the executive’s Form W-2 plus (1) the executive’s share of non-taxable premiums paid for medical and dental insurance and (2) deductions taken from the executive’s compensation to fund the executive’s flexible spending account, each for the calendar year preceding the year of the executive’s termination of employment or preceding the year in which the change in control occurs, whichever is higher. In addition, the executive will continue to participate in benefit plans that provide medical and life insurance for 24 months. If Colonial Federal or its successor cannot provide those benefits, it will either provide the coverage under a comparable individual policy or make a cash equivalent payment to the executive.

Assuming the Merger is completed and Mr. Denizkurt’s employment is terminated, the estimated amount of cash severance and benefits payable under his change in control agreement is estimated to be $465,018, less tax witholdings and reductions necessary to avoid penalties under Sections 280G and 4999 of the Code.

Deferred Compensation Plans. The Company has entered into individual Deferred Compensation Agreements with certain executives, including Mr. McFarland, Ms. Shea, and Mr. Denizkurt, that entitle them to a normal retirement benefit of $25,000 paid in annual installments for 10 years, provided however, that following a change in control, such as the Merger, the executive will receive a payment subject to a predetermined election of either a cash lump sum (equal to the present value of the annual installments) or installment payments, if they have a qualifying termination of employment.

Colonial Federal Savings Bank Employee Stock Ownership Plan. The Colonial Federal Savings Bank Employee Stock Ownership Plan (the “ESOP”) is a tax-qualified plan that covers substantially all of the employees of Colonial Federal who have at least one year of service and have attained age 21. The ESOP received a loan from the Company, the proceeds of which were used to acquire shares of Company Common Stock for the benefit of plan participants. The ESOP has pledged the shares acquired with the loan as collateral for the loan and holds them in a suspense account, releasing them to participants’ accounts as the loan is repaid, with contributions received from Colonial Federal. Effective as of the fifth business day before the closing of the Merger, the ESOP will be terminated. Colonial Federal will repay any outstanding ESOP debt in full by directing the ESOP trustee to first use any cash remaining in the suspense account to repay such ESOP debt and then, if and as necessary, to remit a sufficient number of shares of Company common stock back to the Company to repay any remaining ESOP debt in full, with each remitted share to be valued at $14.25. At the effective time of the Merger, any remaining shares of Company Common Stock held by the ESOP that are unallocated (or the proceeds from the sale thereof, if applicable) will be allocated among the accounts of the ESOP participants with undistributed account balances who are employed by Colonial Federal at the effective time of the Merger, and in proportion to their balances under the ESOP as of the end of the immediately previous plan year.

As a result of the foregoing, Colonial Federal’s executive officers and other active employee participants in the ESOP would receive a benefit in connection with the ESOP’s termination to the extent that the stock price of Company Common Stock multiplied by the number of shares held in the suspense account exceeds the outstanding loan used to acquire those shares.

Approvals Needed to Complete the Merger

In addition to the approval of the Merger Agreement by the shareholders of the Company, the members of 15 Beach, MHC (if required) and Hometown MHC’s corporators, completion of the Merger and the transactions contemplated by the Merger Agreement are subject to the prior approval of the Board of Governors of the Federal Reserve System (the “FRB”) and the Massachusetts Division of Banks.

Federal Reserve. The MHC Merger, the Merger and the Bank Merger are subject to the approval of the FRB (1) pursuant to Section 4 of the Bank Holding Company Act of 1956, as amended (the “BHC Act”), with respect to the MHC Merger and the Merger, and (2) pursuant to Section 18(c)(2)(B) of the Federal Deposit Insurance Act (the “Bank Merger Act”) with respect to the Bank Merger. The FRB takes into consideration a number of factors when acting on applications under Section 4 of the BHC Act and the Bank Merger Act, respectively. These factors include the effect of the applicable transaction on competitiveness in affected banking markets, the financial and managerial resources (including consideration of the capital adequacy, liquidity and earnings performance, as well as the competence, experience and integrity of the officers, directors and principal shareholders, and the records of compliance with applicable laws and regulations) and the combined organization’s future prospects. The FRB also considers the effectiveness of the combined organization in combatting money laundering, the convenience and needs of the communities to be served, as well as the extent to which the proposal would result in greater or more concentrated risks to the stability of the U.S. banking or financial system. The FRB may not approve a proposal that would have significant adverse effects on competition or on the concentration of resources in any banking market.

In considering an application under Section 4 of the BHC Act and the Bank Merger Act, the FRB also reviews the records of performance of the relevant insured depository institutions under the Community Reinvestment Act (the “CRA”), pursuant to which the FRB must also take into account the record of performance of each of Colonial Federal and North Shore Bank in meeting the credit needs of the entire community, including low- and moderate-income neighborhoods, served by their depository institution subsidiaries. As part of the review process in merger transactions, the FRB may receive protests from community groups and others. In their most recent CRA performance evaluations, each of Colonial Federal and North Shore Bank received a “satisfactory” regulatory rating.

Furthermore, the BHC Act and the Bank Merger Act require published notice of, and the opportunity for public comment on, the respective applications. The FRB takes into account the views of third-party commenters, particularly on the subject of the merging parties’ CRA performance and record of service to their communities.

Hometown MHC and Hometown Financial have filed the required application with the FRB related to the MHC Merger and the Merger. North Shore Bank has filed the required application with the FRB relating to the Bank Merger.

Massachusetts Commissioner of Banks. Certain transactions contemplated by the Merger Agreement are subject to approval by the Massachusetts Commissioner of Banks, such as the approval of the Bank Merger pursuant to Massachusetts General Laws Chapter 167I, Section 3. In evaluating a merger application under this section, the Commissioner of Banks will review a proposed Merger to determine whether competition among banking institutions will be unreasonably affected and whether public convenience and advantage will be promoted. In making such determination, the Commissioner will consider, at a minimum, a showing of net new benefits. Net new benefits may include, for example, initial capital investments, job creation plans, consumer and business services, and commitments to maintain and open branch offices within the continuing institution’s CRA assessment area.

Department of Justice. Pursuant to federal law, a period of 15 to 30 days must expire following approval by the FRB within which period the United States Department of Justice may file objections to the Merger under the federal anti-trust laws. While the parties to the Merger Agreement believe that the likelihood of such action by the Department of Justice is remote in this case, there can be no assurance that the Department of Justice will not initiate proceedings to block the Merger. If such a challenge is made, the parties to the Merger Agreement cannot ensure a favorable result.

The Merger cannot proceed in the absence of the requisite regulatory approvals or waivers. See “The Merger Agreement—Conditions to Completing the Merger” and “The Merger Agreement—Other Provisions of the Merger Agreement—Terminating the Merger Agreement.” There can be no assurance as to if and when the requisite regulatory approvals and waivers will be obtained. There can also be no assurance that any regulatory approvals will not contain a condition or requirement that causes the approvals to fail to satisfy the conditions set forth in the Merger Agreement and described under “The Merger Agreement—Conditions to Completing the Merger.”

The approval of any application merely implies the satisfaction of regulatory criteria for approval that does not include review of the Merger from the standpoint of the adequacy of the consideration to be received by shareholders. Furthermore, regulatory approvals do not constitute an endorsement or recommendation of the Merger.

Financing the Merger

The total amount of funds required to consummate the Merger is estimated to be approximately $43.8 million. The funds Hometown Financial will use to satisfy its obligations will be obtained from cash and cash equivalents on hand as of the effective time of the Merger. The Merger is not conditioned on any financing arrangements.

THE MERGER AGREEMENT

The following is a summary of the material terms of the Merger Agreement, a copy of which is attached to this proxy statement as Annex A and incorporated in this proxy statement by reference. This summary may not contain all of the information about the Merger Agreement that is important to you. You should read the entire Merger Agreement carefully. It is the legal document that governs the Merger.

Except for the Merger Agreement’s status as a contractual document that establishes and governs the legal relations of the parties thereto with respect to the Merger and the other transactions contemplated thereby, we do not intend for its text to be a source of factual, business or operational information about the parties to the Merger Agreement. The representations, warranties and covenants made by the parties in the Merger Agreement are qualified and limited, including by information in the disclosure schedules referenced in the Merger Agreement that were delivered in connection with the execution of the Merger Agreement. Representations and warranties may be used as a tool to allocate risks between the respective parties to the Merger Agreement, including where the parties do not have complete knowledge of all facts, instead of establishing such matters as facts. Furthermore, the representations and warranties may be subject to different standards of materiality applicable to the contracting parties, which may differ from what may be viewed as material by our shareholders. These representations and warranties may or may not have been accurate as of any specific date and do not purport to be accurate as of the date of this proxy statement. Moreover, information concerning the subject matter of the representations and warranties may have changed since the date of the Merger Agreement and subsequent developments or new information qualifying a representation or warranty may have been included in this proxy statement. Accordingly, the representations and warranties should not be relied upon as statements of factual information. Company shareholders are not third-party beneficiaries under the Merger Agreement and, therefore, may not directly enforce or rely on its terms and conditions and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the Company.

Structure of the Merger

The Merger Agreement provides that 15 Beach, MHC will merge with Hometown MHC, with Hometown MHC as the surviving corporation (the “MHC Merger”). Following the MHC Merger, the Company will merge with and into Merger Sub, with the Company as the surviving entity (the “Merger”). Following the Merger, the Company will merge with and into Hometown Financial, with Hometown Financial as the surviving corporation (the “Second Step Merger”), and following the Second Step Merger, Colonial Federal will merge with and into North Shore Bank (the “Bank Merger”), with North Shore Bank as the surviving entity.

Closing of the Merger

The closing of the Merger will occur on a date no later than five business days following satisfaction or waiver (subject to applicable law) of all the conditions described in the Merger Agreement, or such other date to be specified by Hometown and the Company. The Merger will become effective upon the filing of articles of merger with the Secretary of the Commonwealth of the Commonwealth of Massachusetts.

The Company and Hometown Financial expect to complete the Merger in the fourth calendar quarter of 2025. However, neither the Company nor Hometown Financial can guarantee when or if the required regulatory approvals will be obtained. See “The Merger—Approvals Needed to Complete the Merger.”

Conditions to Completing the Merger

Among other conditions, the respective obligations of the Company and Hometown Financial to effect the Merger are subject to the satisfaction or waiver of the following conditions specified in the Merger Agreement:

•

approval of the Merger Agreement by the requisite vote of the Company’s shareholders, Hometown MHC’s corporators, and, if required, by 15 Beach, MHC’s members;

•

all approvals, consents or waivers of any governmental entity required to permit consummation of the transactions contemplated by the Merger Agreement being obtained and will remain in full force and effect, and all statutory waiting periods will have expired or been terminated;

no party to the Merger Agreement being subject to any order, decree or injunction of a court or agency of competent jurisdiction that enjoins or prohibits the consummation of the Merger and no governmental entity having instituted any proceeding to enjoin or prohibit the consummation of the Merger or any transactions contemplated by the Merger Agreement and no statute, rule or regulation being enacted, entered, promulgated or enforced by any governmental entity that prohibits or makes illegal consummation of the Merger;

In addition, the obligation of Hometown MHC, Hometown and Merger Sub to complete the Merger is subject to the fulfillment or written waiver, where permissible, of the following conditions:

•

since the date of the Merger Agreement, there will not have occurred any material adverse effect with respect to 15 Beach, MHC or the Company; and

•

none of the approvals, consents or waivers of any governmental entity required to permit consummation of the transactions contemplated by the agreement will contain any condition or requirement that would (1) prohibit or materially limit the ownership or operation by Hometown MHC or any of its subsidiaries of all or any material portion of the business or assets of the Company or its subsidiaries or Hometown MHC or its subsidiaries, (2) compel the Company or its subsidiaries or Hometown MHC or its subsidiaries to dispose of or hold separate all or any material portion of the business or assets of the Company or its subsidiaries or Hometown MHC or its subsidiaries, or (3) compel Hometown MHC or its subsidiaries to take any action, or commit to take any action, or agree to any condition or request, if the prohibition, limitation, condition or other requirement described in clauses (1)-(3) above could reasonably be expected to have a material adverse effect on the future operations by MHC and Hometown of the combined businesses and operations of Hometown Financial’s subsidiaries and Colonial Federal, taken as a whole.

The obligation of the Company to complete the Merger is also conditioned on Hometown Financial having deposited the aggregate merger consideration with the paying agent at least one business day before closing and having caused North Shore Bank to execute and deliver the bank merger agreement.

Under the Merger Agreement, a material adverse effect for 15 Beach, MHC or Hometown Financial, together with their subsidiaries, respectively, means any fact, development, effect, circumstance, occurrence or

change that individually or in the aggregate (1) is material and adverse to the business, properties, assets, liabilities, financial condition, results of operations or business of the Company or MHC, as the context may dictate, and its subsidiaries taken as a whole, or (2) does or would materially prevent, impair or threaten the ability of any of Hometown MHC, Hometown Financial, 15 Beach, MHC or the Company, as the context may dictate, to perform its obligations under the Merger Agreement or otherwise materially threaten or materially impede the consummation of the transactions contemplated by the Merger Agreement; provided, however, that the following (or the impact thereof) will be excluded when determining the existence of a material adverse effect:

•

changes in laws and regulations affecting banks or their holding companies generally, or interpretations thereof by governmental entities;

•

changes in economic conditions affecting financial institutions generally, including but not limited to, changes in the general level of market interest rates;

•

changes in GAAP or regulatory accounting principles generally applicable to financial institutions and their holding companies;

•

the imposition of tariffs or other domestic or international governmental policies, including, but not limited to, changes in government spending, the freezing of government funding or grants, or the shrinking of government workforce, except, with respect to clauses above, unless it uniquely affects any of the parties or their subsidiaries;

•

the announcement of the Merger Agreement and the transactions contemplated hereby, and the effects of complying with the Merger Agreement on the business, financial condition or results of operations of the parties and their respective subsidiaries, including the expenses incurred by the parties in consummating the transactions contemplated by the Merger Agreement; or

•

actions and omissions of a party hereto (or any of a party’s subsidiaries) permitted or required to be taken under the Merger Agreement or taken with the prior written consent of the other party.

You can find the details of the conditions to the Merger in Article VI of the Merger Agreement and the definition of “Material Adverse Effect” located in Annex A. Neither party to the Merger Agreement can guarantee that all of these conditions will be satisfied or waived.

Other Provisions of the Merger Agreement

Although the completion of the Merger requires shareholder approval, many provisions of the Merger Agreement became effective immediately upon its signing. Your vote was not required to make these provisions binding obligations of the Company.

Representations and Warranties. 15 Beach, MHC and its subsidiaries and Hometown MHC, Hometown Financial and its subsidiaries have made certain customary representations and warranties to each other in the Merger Agreement relating to each party’s business. The representations and warranties contained in the Merger Agreement were made only for the purposes of such agreement and are made as of specific dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed to by the contracting parties, including being qualified by confidential disclosure schedules shared between the parties. These representations

and warranties may have been made to allocate risk between the parties to the agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors as statements of factual information.

Each of the Company and Hometown Financial has made representations and warranties to the other regarding, among other things:

•

information technology;

•

Hometown Financial also makes representations regarding the availability of funds to complete the Merger, employee benefit plans and regulatory capitalization. However, because the Merger is an all-cash transaction, the scope of Hometown Financial’s representations and warranties as the buyer are not as broad as that of the Company as the seller.

Cooperation and Conduct of Business.

Under the Merger Agreement, the Company has agreed that, other than as expressly contemplated or permitted by the Merger Agreement or required by law, regulation or any governmental entity during the period from the date of the Merger Agreement to the effective time of the Merger, the Company will not, nor will the Company permit any of its subsidiaries to, without the prior written consent of Hometown Financial, which consent will not be unreasonably withheld, delayed or conditioned:

Agreement Not to Solicit Other Proposals. Between the signing of the Merger Agreement and the completion of the Merger, the Company has agreed not to, and the Company will use its reasonable best efforts to, cause its subsidiaries’ officers, directors or employees or any investment banker, financial advisor, attorney, accountant, consultant or other representative retained by the Company or any of its subsidiaries not to, directly or indirectly:

•

solicit, initiate, induce or encourage, or take any other action to facilitate, any inquiries, offers, discussions or the making of any proposal that constitutes or could reasonably be expected to lead to an acquisition proposal;

•

furnish any information or data regarding the Company or any of its subsidiaries to any person in connection with or in response to an acquisition proposal or an inquiry or indication of interest that would reasonably be expected to lead to an acquisition proposal;

•

continue or otherwise participate in any discussions or negotiations, or otherwise communicate in any way with any person (other than Hometown Financial) other than to inform such person of the terms of its non-solicitation obligations, regarding an acquisition proposal;

•

approve, endorse or recommend any acquisition proposal; or

•

enter into or consummate any agreement, agreement in principle arrangement, letter of intent or understanding contemplating any acquisition proposal or requiring it to abandon, terminate or fail to consummate the transactions contemplated by the Merger Agreement.

Despite the agreement of the Company not to solicit other acquisition proposals, the Company may, at any time before shareholder approval of the Merger, participate in discussions or negotiations regarding an acquisition proposal or furnish, or otherwise afford access to non-public information with respect to the Company or otherwise relating to an acquisition proposal with a third party who makes an unsolicited proposal, provided that, among other things:

•

our board of directors determines, in good faith, after consultation with and considering the advice of the Company’s legal counsel and, with respect to financial matters, its financial advisor, the acquisition proposal constitutes or could reasonably be likely to result in a superior proposal, as set forth in the Merger Agreement;

•

the Company has not otherwise breached its covenants not to solicit acquisition proposals as set forth in the Merger Agreement;

•

our board of directors concludes, in good faith, after considering the advice of our outside counsel, that taking such action would be required in order for the Company’s directors to comply with their fiduciary duties to the Company’s shareholders under applicable law;

•

provides written notice of the identity of such person to Hometown Financial; and

•

the Company has first obtained a confidentiality agreement from the soliciting party on terms no more favorable in the aggregate to such soliciting party than those in the confidentiality agreement between the Company and Hometown Financial.

Under the Merger Agreement, a “superior proposal” means an unsolicited, bona fide written offer or proposal made by a third party (on its most recently amended or modified terms) to consummate an acquisition proposal (with all of the percentages included in the acquisition proposal increased to 50%) that the Company’s board of directors determines in good faith, after consultation with and having considered the advice of outside legal counsel and, with respect to financial matters, its financial advisor, would, if consummated, result in a transaction that (1) involves consideration to the Company shareholders that is more favorable; from a financial point of view, than the consideration to be paid to the Company shareholders pursuant to the Merger Agreement, considering, among other things, the nature of the consideration being offered and any material regulatory approvals or other risks associated with the timing of the proposed transaction beyond, or in addition to, those specifically contemplated by the Merger Agreement, and which proposal is not conditioned on obtaining financing, and (2) is reasonably likely to be completed on the terms proposed, in each case taking into account all legal, financial, regulatory and other aspects of such acquisition proposal.

Employee Matters. Hometown Financial will offer employment to all employees of Colonial Federal who remain employed at the effective time of the Merger. After the Merger, Hometown Financial agrees to provide continuing Colonial Federal employees with base compensation and bonus opportunities that are substantially comparable to the base compensation and bonus opportunities that are generally made available to similarly situated employees of Hometown.

An employee of Colonial (other than an employee who is party to an employment agreement, a severance agreement or a special termination agreement), who is not hired by Hometown Financial or whose employment is involuntarily terminated by Hometown Financial within nine months following the Merger, for a reason other than for “cause” as determined by Hometown Financial, will, subject to the execution and non-revocation of a release agreement in a form reasonably determined by Hometown Financial, be entitled to receive a lump sum cash severance payment equal to two weeks’ severance for each year of continuous service, subject to a minimum of eight weeks and a maximum of 52 weeks of severance.

North Shore Bank will provide to Colonial Federal employees benefits no less favorable than those afforded to other employees of North Shore Bank in similar positions and participation in each North Shore Bank plan of general applicability to the same extent as similarly situated employees. North Shore Bank will cause its benefit plans to recognize, for purposes of determining eligibility and vesting of benefits (but not for benefit accrual or amount of benefits), the services of Colonial Federal employees to the same extent as such service was credited by Colonial Federal. Hometown Financial has sole discretion on whether to terminate, merge or continue any benefit plans or programs of 15 Beach, MHC or its subsidiaries.

With respect to any employee benefit plans of Hometown Financial or its subsidiaries in which any continuing employee becomes eligible to participate on or after the effective time of the Merger (the “new plans”), Hometown Financial has agreed to use commercially reasonable efforts to:

•

cause to be waived all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable such employees and their eligible dependents under the new plans, except to the extent such pre-existing conditions, exclusions or waiting period would apply under the analogous Company employee plan;

•

provide each such employee and their eligible dependents with credit for any eligible expenses incurred by such employee or dependent before the effective time of the Merger under a Company employee plan (to the same extent that such credit was given under the analogous Company employee plan before the effective time of the Merger) in satisfying any applicable deductible, co-payment or out-of-pocket requirements under any new plan; and

•

provide each continuing employee with service credit for eligibility and vesting purposes under any new plan in which continuing employees are eligible to participate for all periods of employment with the Company or any of its subsidiaries prior to the effective time of the Merger, provided that such

service recognition will not apply to the extent it would result in duplication of benefits for the same period of service.

Retention Bonus Pool. Under the Merger Agreement, Hometown Financial and the Company may establish a retention pool to induce retention of employees of the Company and Colonial Federal. Allocation of any retention bonuses will be jointly determined by the Chief Executive Officers of Hometown and the Company. Neither party shall communicate the amounts considered for individual retention bonuses with the affected employees until such amounts are finally determined.

Indemnification and Insurance. Hometown Financial has agreed to indemnify and hold harmless each current and former director, officer or employee of 15 Beach, MHC or its subsidiaries for six years after the effective time of the Merger for claims arising from their position with 15 Beach, MHC or its subsidiaries or their service to 15 Beach, MHC and its subsidiaries, to the fullest extent set forth in the Company’s charter and bylaws on the date of the Merger Agreement or under applicable law. Hometown Financial will also maintain a policy of directors’ and officers’ liability insurance coverage for the benefit of the Company’s directors and officers for six years following consummation of the Merger, subject to certain limitations on the amount of premiums to be paid.

Terminating the Merger Agreement. The Company and Hometown Financial may mutually agree at any time to terminate the Merger Agreement, even if our shareholders have approved the Merger Agreement. In addition, either we or Hometown Financial may decide, without the consent of the other, to terminate the Merger Agreement if:

•

the Company’s shareholders, 15 Beach, MHC’s members, or Hometown Financial’s corporators fail to approve the Merger Agreement, provided that each party can only terminate under this section it has fulfilled its obligations related to calling and holding the special meetings of shareholders, members or corporators;

•

if either a required regulatory approval (A) is denied and such denial is final and non-appealable, or (B) contains a condition or requirement that materially reduce the benefits to either Hometown Financial or the Company from consummating the Merger;

•

if the Merger is not consummated by March 31, 2026 (unless the failure to consummate is due to the action or failure to act by the party seeking to terminate the Merger Agreement); or

•

there is a breach by the other party of any representation, warranty, covenant or agreement contained in the Merger Agreement such that certain conditions to closing of the Merger cannot be met, which breach cannot be cured, or has not been cured within 30 days after giving written notice to such party of the breach; provided that the party seeking termination is not then in material breach of any representation, warranty, covenant or other agreement contained in the Merger Agreement.

We may also terminate the Merger Agreement to enter into an agreement with respect to a superior acquisition proposal, but only if, among other things, we have complied with our obligation not to solicit competing proposals and have paid to Hometown Financial the required fee of $1,550,000. See “—Termination Fee” below.

Hometown Financial may also terminate the Merger Agreement if the Company does not comply with its non-solicitation requirements, does not recommend approval of the Merger Agreement, or changes its recommendation to the Company shareholders regarding the Merger, or it or 15 Beach, MHC breach their obligations to call meetings of their shareholders or members, as required.

Termination Fee. Under certain circumstances, we may be required to pay Hometown Financial a termination fee of $1,550,000. Specifically, the Company must pay the termination fee to Hometown Financial if the Merger Agreement is terminated by Hometown Financial under the following circumstances:

•

Company terminates the Merger Agreement to enter into an agreement with respect to a superior acquisition proposal;

•

Hometown Financial terminates the Merger Agreement because (1) Company has breached its non-solicitation obligations with respect to third-party proposals or holding the Company’s shareholder special meeting or 15 Beach, MHC’s member meeting, or (2) Company’s board of directors does not recommend approval of the Merger Agreement to its shareholders at the Company’s shareholder special meeting or 15 Beach, MHC’s member meeting, or withdraws, modifies or amends its recommendation to approve the Merger Agreement; or

•

Hometown Financial or the Company terminates the Merger Agreement because (a) the Company’s shareholders or 15 Beach, MHC’s members do not approve the Merger Agreement or (b) Colonial is in material breach of its representations, warranties, covenants or agreements and the breach has not been cured within 30 days, and the breach giving rise to such termination was knowing or intentional and

•

at the time of termination, Hometown Financial is not in material breach of any representation, warranty or material covenant;

•

a third-party acquisition proposal is publicly announced, disclosed or communicated and not withdrawn at least two business days before the Company shareholder’s special meeting; and

PROPOSAL 2:

ADJOURNMENT OF THE SPECIAL MEETING

We are submitting a proposal for consideration at the special meeting to approve one or more adjournments of the special meeting if there are not sufficient votes to approve the Merger Agreement and the Merger at the time of the special meeting. Even though a quorum may be present at the special meeting, it is possible that we may not have received sufficient votes to approve the Merger Agreement and the Merger by the time of the special meeting. In that event, we would need to adjourn the special meeting to solicit additional proxies. The Adjournment Proposal relates only to an adjournment of the special meeting to solicit additional proxies to obtain the requisite shareholder approval to approve the Merger Agreement and the Merger. Any other adjournment of the special meeting (e.g., an adjournment required because of the absence of a quorum) would be voted upon pursuant to the discretionary authority granted by the proxy.

The Company’s board of directors recommends that you vote “FOR” the Adjournment Proposal so that proxies may be used for the purpose described above, should it become necessary.

Properly executed proxies will be voted “FOR” the Adjournment Proposal, unless otherwise indicated on the proxies. If the special meeting is adjourned to solicit additional proxies to approve the Merger Agreement and the

Merger, we are not required to give notice of the time and place of the adjourned meeting (other than announcement at the special meeting) unless the meeting is adjourned for more than thirty days.

The Adjournment Proposal relates only to an adjournment of the special meeting occurring to solicit additional proxies for the proposal to approve of the Merger Agreement and the Merger if there are insufficient votes to approve that proposal. The Company’s board of directors retains full authority to the extent set forth in our bylaws to postpone the special meeting before it is convened, without the consent of any of our shareholders.
