#### CATALYST BANCORP, INC.

#### PROXY STATEMENT
**ABOUT THE ANNUAL MEETING OF SHAREHOLDERS**<br>

We are furnishing this proxy statement to holders of common stock of Catalyst Bancorp, Inc., ("Catalyst Bancorp") the parent holding company of Catalyst Bank. Proxies are being solicited on behalf of our Board of Directors for use at the Annual Meeting of Shareholders to be held at our corporate headquarters located at 235 North Court Street, Opelousas, Louisiana 70570 on Tuesday, May 19, 2026, at 8:00 a.m., Central time, and at any adjournment thereof for the purposes set forth in the attached Notice of Annual Meeting of Shareholders. This proxy statement is first being mailed to shareholders on or about April 14, 2026.

***Important Notice Regarding the Availability of Proxy Materials for the Shareholder Meeting to Be Held on May 19, 2026.*** This proxy statement and our 2025 Annual Report are available on our website at:

https://catalystbank.investorroom.com/annual-meeting

#### What is the purpose of the annual meeting?
At our annual meeting, shareholders will act upon the matters outlined in the attached Notice of Annual Meeting of Shareholders, including the election of directors and the ratification of our independent registered public accounting firm. In addition, management may report on the performance of Catalyst Bancorp and respond to questions from shareholders.

#### Who is entitled to vote?
Only our shareholders of record as of the close of business on the voting record date for the annual meeting, March 30, 2026, are entitled to vote at the meeting. On the record date, we had 4,058,297 shares of common stock issued and outstanding and no other class of equity securities outstanding. For each issued and outstanding share of common stock you own on the record date, you will be entitled to one vote on each matter to be voted on at the meeting, in person or by proxy.

#### How do I vote my shares?
After you have carefully read this proxy statement, indicate on your proxy card or voting instruction form how you want your shares to be voted. Then sign, date and mail your proxy card or voting instruction form in the enclosed prepaid return envelope or vote electronically over the Internet as soon as possible. This will enable your shares to be represented and voted at the annual meeting. Proxy cards from record shareholders of Catalyst Bancorp, Inc., must be received by Internet or by mail by 11:59 p.m. Eastern time on Monday, May 18, 2026. You can revoke a proxy at any time prior to its exercise at the meeting by following the instructions in this accompanying proxy statement. Voting instructions from participants in the Catalyst Bancorp, Inc. Employee Stock Ownership Plan and Catalyst Bank 401(k) Plan must be received by Internet or by mail by 11:59 p.m. Eastern time on Tuesday, May 12, 2026, to be used by the plan Trustees to determine the votes for plan shares. Most shareholders whose shares are held in "street" name with brokers or other nominees can also vote their shares by telephone. If telephone voting is available to you, voting instructions are printed on the voting instruction form furnished by the broker or other nominee.

***If my shares are held in "street name" by my broker, could my broker automatically vote my shares?***

Your broker may not vote on the election of directors if you do not furnish instructions for such proposal. You should use the voting instruction form or broker card provided by the institution that holds your shares to instruct your broker to vote your shares or else your shares may not be voted or may be considered "broker non-votes." Your broker may vote in his or her discretion on the ratification of the appointment of our independent registered public accounting firm if you do not furnish instructions. If your broker votes in his or her discretion on proposal two and you did not provide instructions for proposals one, then your shares will be considered "broker non-votes" on proposal one.

[**Table of Contents**](#TOC)

#### Can I attend the meeting and vote my shares in person?
All shareholders are invited to attend the annual meeting. Shareholders of record can vote in person at the annual meeting. If your shares are held in "street name," then you are not the shareholder of record and you must ask your broker or other nominee about how you can vote at the annual meeting.

#### Can I change my vote after I return my proxy card?
Yes. If you are a shareholder of record, there are three ways you can change your vote or revoke your proxy after you have sent in your proxy card.

● First, you may complete and submit a new proxy card. Any earlier proxies will be revoked automatically.

● Second, you may send a written notice to the Secretary of Catalyst Bancorp, Inc., Mr. Ted D. Bellard, Corporate Secretary, Catalyst Bancorp, Inc., 235 North Court Street, Opelousas, Louisiana 70570, in advance of the meeting stating that you would like to revoke your proxy.

● Third, you may attend the annual meeting and vote in person. Any earlier proxy will be revoked. However, attending the annual meeting without voting in person will not revoke your proxy.

If your shares are held in street name and you have instructed a broker or other nominee to vote your shares, you must follow directions you receive from your broker or other nominee to change your vote.

#### What constitutes a quorum?
The presence at the annual meeting, in person or by proxy, of the holders of a majority of the votes that all shareholders are entitled to cast at the annual meeting will constitute a quorum. Proxies received but marked as abstentions and broker non-votes will be included in the calculation of the number of votes considered to be present at the meeting.

#### What are the Board of Directors' recommendations?
The recommendations of the Board of Directors are set forth under the description of each proposal in this proxy statement. In summary, the Board of Directors recommends that you vote (i) **FOR** the nominees for director described herein, and (ii) **FOR** ratification of the appointment of BDO USA, P.C.as our independent registered public accounting firm for the year ending December 31, 2026.

The proxy solicited hereby, if properly signed and returned to us and not revoked prior to its use, will be voted in accordance with your instructions contained in the proxy. If no contrary instructions are given, each proxy signed and received will be voted in the manner recommended by the Board of Directors and, upon the transaction of such other business as may properly come before the meeting, in accordance with the best judgment of the persons appointed as proxies to the extent authorized under Rule 14a-4(c) under the Securities Exchange Act of 1934. Proxies solicited hereby may be exercised only at the annual meeting and any adjournment of the annual meeting and will not be used for any other meeting.

#### What vote is required to approve each item?
Directors are elected by a plurality of the votes cast with a quorum (i.e., a majority of the outstanding shares entitled to vote represented in person or by proxy) present. The two persons who receive the greatest number of votes of the holders of common stock represented in person or by proxy at the annual meeting will be elected directors. The affirmative vote of a majority of the votes cast by shareholders entitled to vote at the annual meeting is required for the approval of the proposal to ratify the appointment of our independent registered public accounting firm for the year ending December 31, 2026. Abstentions and broker non-votes are considered in determining the presence of a quorum but will not affect the vote required on the proposals to be considered at the Annual Meeting.

&nbsp;&nbsp;**INFORMATION WITH RESPECT TO NOMINEES FOR DIRECTOR,**<br>**CONTINUING DIRECTORS AND EXECUTIVE OFFICERS**<br>

#### Election of Directors (Proposal One)
Our Articles of Incorporation provide that the Board of Directors will be divided into three classes as nearly equal in number as the then total number of directors constituting the Board of Directors permits. The directors are elected by our shareholders for staggered terms, and until their successors are elected and qualified. At the annual meeting, shareholders of Catalyst Bancorp will be asked to elect one class of directors, consisting of two directors, for a three-year term expiring in 2029, and until their successors are elected and qualified.

Our Nominating and Corporate Governance Committee has recommended the re-election of Messrs. Lafleur and Scruggins as directors. No director is related to any other director or executive officer by first cousin or closer. Each nominee and each director whose term continues currently serves as a director of Catalyst Bancorp and its subsidiary, Catalyst Bank.

Unless otherwise directed, each proxy card signed and returned by a shareholder will be voted for the election of the nominees for director listed in the table below. If any person named as a nominee should be unable or unwilling to stand for election at the time of the annual meeting, the proxies will nominate and vote for any replacement nominee or nominees recommended by our Board of Directors. At this time, the Board of Directors knows of no reason why any of the nominees listed in the table below may not be able to serve as a director if elected.

The tables below and on the following page present information concerning the nominees for director and each director whose term continues, including tenure as a director. Terms as directors for all directors include service as a director of Catalyst Bank prior to the formation of Catalyst Bancorp in 2021. Ages are reflected as of March 30, 2026.

**Audit Committee.** The primary purpose of the Audit Committee, as set forth in the committee's charter, is to assist the Board of Directors in fulfilling its fiduciary responsibilities relating to corporate accounting and reporting practices. The Audit Committee reviews with management and the independent auditors the systems of internal control, reviews the annual financial statements, including the Annual Report on Form 10-K, and monitors our adherence in accounting and financial reporting to generally accepted accounting principles. The Board of Directors has identified Mr. LeBouef as a member of the Audit Committee who meets the Securities and Exchange Commission's definition of audit committee financial expert. The Board of Directors believes that all of the Audit Committee members have sufficient expertise to fulfill their fiduciary duties. The Audit Committee meets on an as needed basis and met six times in 2025.

**Compensation Committee**. The Compensation Committee reviews the compensation of our executive officers and met four times in 2025. No member of the Compensation Committee is a current or former officer or employee of Catalyst Bancorp or Catalyst Bank.

**Nominating and Corporate Governance Committee**. Nominations for director of Catalyst Bancorp are reviewed by the Nominating and Corporate Governance Committee and submitted to the full Board of Directors for approval. The Nominating and Corporate Governance Committee met once during 2025.

#### Board Leadership Structure
Our Board of Directors is led by a Chairman selected by the Board from time to time. Presently, Mr. Kidder serves as Chairman of the Board. Other than Mr. Zanco, our President and Chief Executive Officer, all of our other directors are independent.

The Board of Directors has determined that the separation of the offices of Chairman of the Board and President enhances Board independence and oversight. Further, the separation of the Chairman of the Board permits the President and Chief Executive Officer to better focus on his responsibilities of managing the daily operations of Catalyst Bancorp and Catalyst Bank, enhancing shareholder value and expanding and strengthening our franchise while allowing the Chairman of the Board to lead the Board of Directors in its fundamental role of providing independent oversight and advice to management. Mr. Kidder is an independent director under the rules of the Nasdaq Stock Market.

#### Board's Role in Risk Oversight
Risk is inherent with every business, particularly financial institutions. We face a number of risks, including credit risk, interest rate risk, liquidity risk, operational risk, strategic risk, and cybersecurity risk. Management is responsible for the day-to-day management of the risks Catalyst Bancorp and Catalyst Bank face, while the Board, as a whole and through its committees, has responsibility for the oversight of risk management. The Board of Directors regularly discusses with management our major risk exposures, their potential impact on our business and steps taken to address them.

Members of senior management regularly attend meetings of the Board of Directors and address any questions or concerns raised by the Board on risk management or other matters. The Board's risk oversight function is carried out through, among other factors, its review and approval of various policies and procedures, such as Catalyst Bank's lending and investment policies, ratification or approval of investments and loans exceeding certain thresholds, and regular review of risk elements such as interest rate risk exposure, liquidity and problem assets. In addition, members of management keep the Board informed of the state of our cybersecurity posture and any developments or incidents related to our cybersecurity exposure.

#### Directors' Attendance at Annual Meetings
Although we do not have a formal policy regarding attendance by members of the Board of Directors at annual meetings of shareholders, we expect that our directors will attend, absent a valid reason for not doing so. All of our seven directors attended our annual meeting of shareholders held on May 20, 2025.

[**Table of Contents**](#TOC)

#### Clawback Policy
In 2023, Catalyst Bancorp's (the "Company") Board of Directors instituted a "clawback" policy with respect to incentive compensation. The clawback policy mitigates the risks associated with the Company's compensation policies, because certain employees will be required to repay compensation in the circumstances identified in the policy. The clawback policy provides that the Board of Directors will seek recoupment of incentive-based compensation paid or granted to our named executive officers in the event of a material restatement of the Company's financial statements due to material non-compliance with any financial reporting requirements under Federal securities laws. If the Company was required to prepare an accounting restatement, the policy requires the board to seek to recover amounts of incentive compensation erroneously paid (that is, the excess of what amounts would have been paid to the executive under the restated financial statements) to the named executive officer during the three years preceding such restatement. The Board of Directors will reevaluate and, if necessary revise the Company's clawback policy to comply with applicable law or any rules or standards adopted by a national securities exchange on which the Company's securities are listed.

#### Outstanding Equity Awards at Fiscal Year-End
The table below sets forth outstanding equity awards at December 31, 2025 to our named executive officers.

#### Employment Agreements

Pursuant to the agreement, Mr. Zanco serves as President and Chief Executive Officer for a term of three years ending August 17, 2026.

In September 2023, Catalyst Bank entered into an employment agreement with Amanda B. Quebedeaux, Senior Vice President and Chief Operations Officer for a term of three years ending in September 2026.

#### Retirement Benefits
Retirement benefits are an important element of a competitive compensation program for attracting senior executives, especially in the financial services industry. Our executive compensation program currently includes (i) a 401(k) plan which enables our employees to supplement their retirement savings with elective deferral contributions and permits matching and discretionary contributions by us, and (ii) an employee stock ownership plan that allows participants to accumulate retirement benefits in the form of employer stock at no current cost to the participant.

**401(k) Plan.** Catalyst Bank sponsors the Catalyst Bank 401(k) Plan, which is a qualified, tax-exempt defined contribution plan with a salary deferral feature under Section 401(k) of the Internal Revenue Code. An employee of Catalyst Bank is eligible to become a participant in the plan after completing one month of employment in which the employee completed at least 83.3 hours of service. Eligible employees are entitled to enter the 401(k) plan on a monthly basis.

Under the 401(k) plan, during 2025 participants were permitted to make salary deferral contributions (in whole percentages) up to the maximum percentage of compensation allowed by law ($23,500 for 2025). Participants who are age 50 or older are permitted to make "catch up" contributions to the plan up to $7,500 (for 2025, as indexed annually). Participants who are age 60, 61, 62 and 63 are permitted to make "catch up" contributions to the plan up to $11,250 (for 2025, as indexed annually). During 2025, Catalyst Bank contributed a matching contribution amount up to 4% of the participant's annual compensation.

[**Table of Contents**](#TOC)

**Employee Stock Ownership Plan.** Catalyst Bancorp has established an employee stock ownership plan for our employees who have been credited with at least 1,000 hours of service during a 12-month period. As part of the conversion offering completed in October 2021, the employee stock ownership plan purchased 8.0% of the common stock issued in the conversion, or 423,200 shares, from Catalyst Bancorp utilizing a loan equal to 100% of the aggregate purchase price of the common stock acquired by our employee stock ownership plan. The loan to the employee stock ownership plan, which has a term of 20 years, is being repaid principally from Catalyst Bank's contributions to the employee stock ownership plan, and the collateral for the loan is the common stock purchased by the employee stock ownership plan. We may, in any plan year, make additional discretionary contributions for the benefit of plan participants in either cash or shares of common stock, which may be acquired through the purchase of outstanding shares in the market or from individual shareholders, upon the original issuance of additional shares by Catalyst Bancorp or upon the sale of treasury shares by Catalyst Bancorp.

Shares purchased by our employee stock ownership plan with the loan proceeds are held in a suspense account and released for allocation to participants on a pro rata basis as debt service payments are made. Shares released from the employee stock ownership plan are allocated to each eligible participant's employee stock ownership plan account based on the ratio of each such participant's compensation, consisting of salary and bonus, to the total of such compensation of all eligible employee stock ownership plan participants. Forfeitures may be used for several purposes such as the payment of expenses or be reallocated among remaining participating employees. Account balances of participants in the employee stock ownership plan will be 100% vested after five years of service. Credit is given for years of service with Catalyst Bank prior to adoption of the employee stock ownership plan. In the case of a "change in control," as defined in the employee stock ownership plan, however, participants will become immediately fully vested in their account balances. Participants will also become fully vested in their account balances upon death, disability or retirement. Benefits may be payable upon retirement or separation from service.

#### Transactions With Related Persons
Catalyst Bank offers extensions of credit to its directors and executive officers as well as members of their immediate families for the financing of their primary residences and other purposes. These loans are made in the ordinary course of business, on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with persons not related to Catalyst Bank, and none of such loans involve more than the normal risk of collectibility or present other unfavorable features. At December 31, 2025, such loans total approximately $1.6 million.

The Sarbanes-Oxley Act of 2002 generally prohibits a public company from extending or renewing credit or arranging the extension or renewal of credit to an officer or director. However, this prohibition does not apply to loans made by depository institutions, such as Catalyst Bank, that are insured by the Federal Deposit Insurance Corporation and are subject to the insider lending restrictions of the Federal Reserve Board's Regulation O. Accordingly, we permit our directors and executive officers, their family members and their related interests, to establish and maintain banking and business relationships in the ordinary course of business with Catalyst Bank. With respect to lending activities, Catalyst Bank has policies governing affiliate and insider lending transactions. These policies prohibit extensions of credit to "insiders," as defined in the policies, unless the extension of credit (i) is made in the ordinary course of business on substantially the same terms (including interest rates and collateral) as, and following credit underwriting procedures that are not less stringent than, those prevailing at the time for comparable transactions with members of the general public (unless the loans are made pursuant to a benefit or compensation program that is widely available to employees of Catalyst Bank and does not give preference to any director, executive officer or principal shareholder), and (ii) does not involve more than the normal risk of repayment or present other unfavorable features.

#### Insider Trading Policy
The Company has adopted a Statement of Policy and Procedures Governing Trading in Shares of Catalyst Bancorp., Inc. ("Insider Trading Policy") which is reasonably designed to promote compliance with insider trading laws, rules and regulations, and standards of Nasdaq Capital Market. The Insider Trading Policy governs the purchase, sale and/or other disposition of the Company's common stock by the Company's directors, executive officers and all other Company and Bank personnel. The Insider Trading Policy can be found as Exhibit 19 to the Current Report on Form 10-K for Catalyst Bancorp.

#### Delinquent Section 16(a) Reports
Section 16(a) of the Securities Exchange Act of 1934 requires certain of our officers and our directors, and persons who own more than 10% of Catalyst Bancorp, Inc.'s common stock to file reports of ownership and changes in ownership with the Securities and Exchange Commission. Officers, directors and greater than 10% shareholders are required by regulation to furnish us with copies of all Section 16(a) forms they file. Based solely on information provided to the Company by individual directors and officers, we believe that all our Section 16 filers complied with the filing requirements during the fiscal year, except for a Form 4 for Don P. Ledet omitting 553 shares of stock that were disposed solely to meet tax obligation for distribution from stock benefit plan. A Form 5 reflecting the shares was subsequently filed on February 5, 2026.

**RATIFICATION OF APPOINTMENT OF**<br>**INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (Proposal Two)**<br>

As previously reported on Form 8-K filed on November 26, 2024, which is incorporated herein by reference, HORNE LLP ("HORNE") was approved as Catalyst Bancorp's (the "Company") independent registered public accounting firm for the Company's fiscal year ending December 31, 2025, which was ratified at the 2025 Annual Meeting. On November 6, 2025, the Company reported on Form 8-K, which is incorporated herein by reference, that the partners and professional staff of HORNE joined BDO USA, P.C. ("BDO"). As a result of this transaction, HORNE resigned as the Company's independent registered public accounting firm on October 31, 2025. On November 5, 2025, following the resignation of HORNE, the Company, through and with the approval of the Audit Committee, appointed BDO as its independent registered public accounting firm.

As a result of their resignation, HORNE did not issue reports on the financial statements of the Company. Castaing, Hussey & Lolan, LLC ("Castaing") served as the Company's independent registered public accounting firm since the Company's inception in 2021 through March 28, 2025, and therefore issued reports on the financial statements of the Company for the fiscal year ended December 31, 2024.

During the period beginning on March 28, 2025 and through October 31, 2025, there were no disagreements between the Company and HORNE on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of HORNE, would have caused HORNE to make reference to the subject matter of the disagreements in connection with its audit reports on the Company's financial statements. During the fiscal year ended December 31, 2024, and the subsequent interim period through March 28, 2025, HORNE did not advise the Company of any of the matters specified in Item 304(a)(1)(v) of Regulation S-K.

During the Company's fiscal year ended December 31, 2024 and through the date of engagement of BDO, neither the Company nor anyone on behalf of the Company consulted with BDO regarding (a) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company's financial statements as to which the Company received a written report or oral advice that was an important factor in reaching a decision on any accounting, auditing or financial reporting issue; or (b) any matter that was the subject of a disagreement or a reportable event as defined in Item 304(a)(1)(iv) and (v), respectively, of Regulation S-K.

The Company has been advised that neither BDO nor any of its partners has any direct or any material indirect financial interest in the securities of the Company or any of its subsidiaries, except as auditors and consultants on accounting procedures. The Board does not anticipate that representatives of BDO will attend the Annual Meeting.

#### Audit Fees
The following table sets forth the aggregate fees billed by BDO and Castaing for professional services in connection with the audit of our financial statements for the years ended December 31, 2025 and 2024 and fees paid by us to Castaing for audit-related services rendered by Castaing during fiscal 2024.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Audit fees consist of fees for professional services rendered for the audit of our financial statements, review of financial statements included in Catalyst Bancorp's quarterly reports, and for services normally provided by the independent auditor in connection with statutory and regulatory filings or engagements.

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;(2) All other fees consist of other permissible services by an independent registered public accounting firm, including review of management's accounting for certain items during the year.

The Audit Committee selects our independent registered public accounting firm and pre-approves all audit services to be provided by it to Catalyst Bancorp. The Audit Committee also reviews and pre-approves all audit-related and non-audit related services rendered by our independent registered public accounting firm in accordance with the Audit Committee's charter. In its review of these services and related fees and terms, the Audit Committee considers, among other things, the possible effect of the performance of such services on the independence of our independent registered public accounting firm. The Audit Committee pre-approves certain audit-related services and certain non-audit related tax services which are specifically described by the Audit Committee on an annual basis and separately approves other individual engagements as necessary.

Each new engagement of the Company's independent registered public accounting firm was approved in advance by the Audit Committee or its Chair, and none of those engagements made use of the de minimis exception to pre-approval contained in the SEC's rules.

#### Although not required to do so, the Board has chosen to submit its appointment of BDO USA, P.C. for

#### ratification by the Company's shareholders.
**The Board of Directors recommends that you vote FOR the ratification of the appointmentof BDO USA, P.C. as our independent registered public accounting firmfor the fiscal year ending December 31, 2026.**

**REPORT OF THE AUDIT COMMITTEE**<br>

The Audit Committee has reviewed and discussed Catalyst Bancorp's audited consolidated financial statements with management. The Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed in PCAOB Auditing Standard No. 16, *(Communications with Audit Committees)*. The Audit Committee has received the written disclosures and the letter from the independent accountant required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant's communications with the Audit Committee concerning independence and has discussed with the independent accountant their independence. Based on the review and discussions referred to above in this report, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements be included in Catalyst Bancorp's Annual Report on Form 10-K for fiscal year ended December 31, 2025, for filing with the Securities and Exchange Commission.
