Under the terms of the ESOP, shares of common stock in the ESOP are voted by the ESOP trustees in a manner proportionate to the voting directions of the allocated shares received by the ESOP participants, subject to the fiduciary duties of the trustees.

#### Quorum
The presence in person or by proxy of holders of a majority of the total number of outstanding shares of common stock entitled to vote is necessary to constitute a quorum at the annual meeting. Abstentions and broker non-votes will be counted for purposes of determining that a quorum is present. In the event there are not sufficient votes for a quorum, or to approve or ratify any matter being presented at the time of the annual meeting, the annual meeting may be adjourned in order to permit the further solicitation of proxies.

#### Votes Required
As to the election of directors, the proxy card being provided by the Board of Directors enables a stockholder: (i) to vote FOR ALL nominees proposed by the Board; (ii) to WITHHOLD for ALL nominees; or (iii) to vote FOR ALL EXCEPT one or more of the nominees being proposed. Directors are elected by a plurality of votes cast, without regard to either broker non-votes or proxies as to which the authority to vote for the nominees being proposed is withheld. Plurality means that individuals who receive the highest number of votes cast are elected, up to the maximum number of directors to be elected at the annual meeting.

As to the ratification of the appointment of Bonadio & Co., LLP as our independent registered public accounting firm for the year ending December 31, 2026, by checking the appropriate box, a stockholder may: (i) vote FOR the ratification; (ii) vote AGAINST the ratification; or (iii) ABSTAIN from voting on such ratification. The ratification of this matter shall be determined by a majority of the votes represented at the annual meeting and entitled to vote on the matter, without regard to proxies marked ABSTAIN or broker non-votes.

As to the advisory, non-binding approval of the resolution with respect to our NEO compensation as described in this Proxy Statement, a stockholder may: (i) vote FOR the resolution; (ii) vote AGAINST the resolution; or (iii) ABSTAIN from voting on the resolution. The affirmative vote of a majority of the votes cast at the annual meeting, without regard to broker non-votes and proxies marked ABSTAIN, is required for the approval of the non-binding resolution. While this vote is required by law, it will neither be binding on Seneca Bancorp or the Board of Directors, nor will it create or imply any change in the fiduciary duties of, or impose any additional fiduciary duty on, Seneca Bancorp or the Board of Directors.

As to the advisory non-binding vote on the approval of the frequency of the advisory votes on NEO compensation, stockholders may: (i) vote ONE YEAR; (ii) vote TWO YEARS; (iii) vote THREE YEARS, or (iv) ABSTAIN from voting on such matter. The option that receives the most votes at the annual meeting will be considered by the Board of Directors in determining the preferred frequency with which Seneca Bancorp will hold a stockholder vote to approve the compensation of its NEOs.

#### Effect of Not Casting Your Vote
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. If you hold your shares in street name, it is critical that you cast your vote if you want it to count in the election of directors (Proposal 1), the advisory vote on NEO compensation (Proposal 3), and the frequency of the advisory votes on NEO compensation (Proposal 4). Current regulations restrict the ability of your bank, broker or other holder of record to vote your shares in certain matters on a discretionary basis. Therefore, if you hold your shares in street name and you do not instruct your bank, broker or other holder of record on how to vote in Proposals 1, 3, and 4, no votes will be cast on your behalf. These are referred to as "broker non-votes." Your bank, broker or other holder of record, however, does continue to have discretion to vote any shares for which you do not provide instructions on how to vote on the ratification of the appointment of the independent registered public accounting firm (Proposal 2). If you are a stockholder of record and you do not cast your vote, no votes will be cast on your behalf on any of the items of business at the annual meeting.

#### Participants in the Amended and Restated Seneca Savings Bank, National Association Employee Stock Ownership Plan or the Seneca Savings Bank 401(k) Plan
If you participate in the Amended and Restated Seneca Savings Bank, National Association Employee Stock Ownership Plan (the "ESOP"), you will receive a Vote Authorization Form for the ESOP that reflects all of the shares you may direct the trustees 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 each ESOP participant may direct the trustee how to vote the proportionate interest of shares of our common stock allocated or deemed allocated to his or her account. The ESOP trustee, subject to the exercise of its fiduciary responsibilities, will vote all unallocated shares of our common stock held by the ESOP and allocated shares for which no voting instructions are received in the same proportion as shares for which it has received timely voting instructions, subject to a determination that such vote is in the best interest of ESOP participants.

In addition, participants in the Seneca Savings Bank 401(k) Plan ("401(k) Plan") who have assets invested in Seneca Bancorp common stock will receive a Vote Authorization Form that allows them to direct the 401(k) Plan trustee to vote their shares held by the 401(k) Plan. If a participant does not direct the 401(k) Plan trustee as to how to vote his or her shares in the 401(k) Plan, the trustee will vote such interest in the same proportion as it has received voting instructions from other 401(k) Plan participants. **The deadline for returning your ESOP Vote Authorization Form and/or 401(k) Vote Authorization Form is Tuesday, May 12, 2026 at 5:00 p.m. local time.**

#### PROPOSAL I—ELECTION OF DIRECTORS
Our Board of Directors is currently comprised of seven members. Our Bylaws provide that directors are divided into three classes as nearly equal in number as possible, with one class of directors elected annually. Kimberly Boynton and Joseph Vitale have been nominated for election at the annual meeting to serve for a three-year and one-year period, respectively, and until their respective successors shall have been elected and qualified. Each nominee is currently a director of Seneca Bancorp.

The following sets forth certain information regarding the nominees and the other current members of our Board of Directors, including the terms of office of board members. It is intended that the proxies solicited on behalf of the Board of Directors (other than proxies in which the vote is withheld as to any nominee) will be voted at the annual meeting for the election of the proposed nominees. If a nominee is unable to serve, the shares represented by all such proxies will be voted for the election of such substitute as the Board of Directors may determine. At this time, the Board of Directors knows of no reason why any of the nominees might be unable to serve, if elected. Except as indicated herein, there are no arrangements or understandings between any nominee or continuing director and any other person pursuant to which such nominee or continuing director was selected. Age information is as of December 31, 2025, and term as a director includes service with Seneca Savings Bank, National Association ("Seneca Savings Bank").

With respect to directors and nominees, the biographies contain information regarding the person's business experience and the experiences, qualifications, attributes or skills that caused the Board of Directors to determine that the person should serve as a director. Each director of Seneca Bancorp is also a director of Seneca Savings Bank.

#### Board Independence
The Board of Directors has determined that each of our directors, except for Joseph G. Vitale and Vincent J. Fazio, is "independent" as defined in the listing standards of the Nasdaq Stock Market. Messrs. Vitale and Fazio are not independent because they are employed as executive officers of Seneca Bancorp and Seneca Savings Bank. The board of directors did not consider any other transactions, relationships and arrangements between Seneca Bancorp and its directors which are not required to be reported under "—Transactions with Certain Related Persons."

#### Board Leadership Structure and Risk Oversight
Our Board of Directors is chaired by Mark Zames, who is an independent director. This ensures a greater role for the independent directors in the oversight of Seneca Bancorp and Seneca Savings Bank and active participation of the independent directors in setting agendas and establishing priorities and procedures for the work of the Board.

To further assure effective independent oversight, the Board of Directors has adopted a number of governance practices, including:

● a majority independent Board of Directors;

● periodic meetings of the independent directors; and

● annual performance evaluations of the President and Chief Executive Officer by the Compensation Committee.

The Board of Directors recognizes that, depending on the circumstances, other leadership models might be appropriate. Accordingly, the Board of Directors periodically reviews its leadership structure.

The Board of Directors is actively involved in oversight of risks that could affect Seneca Bancorp. This oversight is conducted primarily through committees of the Board of Directors, but the full Board of Directors has retained responsibility for general oversight of risks. The Board of Directors also satisfies this responsibility through reports by the committee chair of all board committees regarding the committees' considerations and actions, through review of minutes of committee meetings and through regular reports directly from officers responsible for oversight of particular risks within Seneca Bancorp. Risks relating to the direct operations of Seneca Savings Bank are further overseen by the Board of Directors of Seneca Savings Bank, a majority of whom are the same individuals who serve on the Board of Directors of Seneca Bancorp. The Board of Directors of Seneca Savings Bank also has additional committees that conduct risk oversight. All committees are responsible for the establishment of policies that guide management and staff in the day-to-day operation of Seneca Bancorp and Seneca Savings Bank such as lending, risk management, asset/liability management, investment management and others.

#### Section 16(a) Delinquent Reports
Our executive officers and directors and beneficial owners of greater than 10% of the outstanding shares of common stock are required to file reports with the Securities and Exchange Commission disclosing beneficial ownership and changes in beneficial ownership of our common stock. Securities and Exchange Commission rules require disclosure if an executive officer, director or 10% beneficial owner fails to file these reports on a timely basis. Based on our review of ownership reports required to be filed for the year ended December 31, 2025, no executive officer, director or 10% beneficial owner of our shares of common stock failed to file ownership reports with the Securities and Exchange Commission on a timely basis.

#### Code of Ethics for Senior Officers
Seneca Bancorp has adopted a Code of Ethics for Senior Officers that applies to Seneca Bancorp's principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. The Code of Ethics for Senior Officers is available on our website at https://www.senecasavings.com/investor-relations/. Amendments to and waivers from the Code of Ethics for Senior Officers will also be disclosed on our website.

#### Policy on Insider Trading
Seneca Bancorp has adopted a Policy on Insider Trading governing the purchase, sale, and/or other dispositions of our securities by our directors, officers and employees as well as by Seneca Bancorp itself that we believe is reasonably designed to promote compliance with insider trading laws, rules and regulations. A copy of our Policy on Insider Trading was filed as Exhibit 19 to Seneca Bancorp's Annual Report on Form 10-K for the year ended December 31, 2025.

#### Anti-Hedging Policy
Seneca Bancorp's anti-hedging and anti-pledging provisions are covered in its Policy on Insider Trading. Under the policy, directors and executive officers are prohibited from engaging in short sales of Seneca Bancorp stock, and unless specifically approved by the Board of Directors, from engaging in transactions in publicly-traded options, such as puts, calls and other derivative securities based on Seneca Bancorp stock including any hedging, monetization or similar transactions designed to decrease the risks associated with holding Seneca Bancorp stock. The Board of Directors has not approved and does not intend to approve such a program. In addition, directors and executive officers are generally prohibited from pledging Seneca Bancorp stock as collateral for any loan or holding Seneca Bancorp stock in a margin account. The Board of Directors may approve an exception to this policy for a pledge of Seneca Bancorp stock as collateral for a loan from a third party (not including margin debt) where the borrower clearly demonstrates the financial capacity to repay the loan without resort to the pledged securities. The Board of Directors has not approved any such exception to its policy.

#### Attendance at Annual Meetings of Stockholders
Seneca Bancorp does not have a written policy regarding director attendance at annual meetings of stockholders, although directors are expected to attend these meetings absent unavoidable scheduling conflicts. Seven directors attended the 2025 Annual Meeting of Stockholders.

#### Communications with the Board of Directors
Any stockholder who wishes to contact our Board of Directors or an individual director may do so by writing to: Seneca Bancorp, Inc., 35 Oswego Street, Baldwinsville, New York 13027, Attention: Board of Directors. The letter should indicate that the sender is a stockholder and, if shares are not held of record, should include appropriate evidence of stock ownership. Communications are reviewed by the Corporate Secretary and are then distributed to the Board of Directors or the individual director, as appropriate, depending on the facts and circumstances outlined in the communications received. The Corporate Secretary may attempt to handle an inquiry directly (for example, where it is a request for information about Seneca Bancorp or it is a stock-related matter). The Corporate Secretary has the authority not to forward a communication if it is primarily commercial in nature, relates to an improper or irrelevant topic, or is unduly hostile, threatening, illegal or otherwise inappropriate. At each Board of Directors meeting, the Corporate Secretary shall present a summary of all communications received since the last meeting that were not forwarded and make those communications available to the directors on request.

#### Meetings and Committees of the Board of Directors
The business of Seneca Bancorp is conducted at regular and special meetings of the Board of Directors and its committees. In addition, the "independent" members of the Board of Directors (as defined in the listing standards of the Nasdaq Stock Market) meet in executive sessions. The standing committees of the Board of Directors of Seneca Bancorp are the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee.

The Board of Directors of Seneca Bancorp held 12 regular meetings during the year ended December 31, 2025. Seneca Savings Bank held 12 regular meetings and no special meetings during the year ended December 31, 2025. No member of the Board of Directors or any committee thereof attended fewer than 75% of the aggregate of: (i) the total number of meetings of the Board of Directors (held during the period for which he has been a director); and (ii) the total number of meetings held by all committees on which he or she served (during the periods that he or she served).

***Audit Committee.*** The Audit Committee is comprised of Directors Boynton, Duteau and Zames each of whom is "independent" in accordance with applicable Securities and Exchange Commission rules and Nasdaq listing standards. Director Boynton serves as chair of the Audit Committee. The Board of Directors has determined that Director Boynton qualifies as an "audit committee financial expert" as defined under applicable Securities and Exchange Commission rules.

Our Board of Directors has adopted a written charter for the Audit Committee, which is available on our website at https://www.senecasavings.com/investor-relations/. As more fully described in the Audit Committee Charter, the Audit Committee reviews the financial records and affairs of Seneca Bancorp and monitors adherence in accounting and financial reporting to accounting principles generally accepted in the United States of America. The Audit Committee met seven times during the year ended December 31, 2025.

***Compensation Committee.*** The Compensation Committee was comprised of Directors Boynton, Zames and Le Beau each of whom is "independent" in accordance with applicable Nasdaq listing standards. Director Boynton served as chair of the Compensation Committee. The Compensation Committee met four times during the year ended December 31, 2025.

With regard to compensation matters, the Compensation Committee's primary purposes are to discharge the Board's responsibilities relating to the compensation of the Chief Executive Officer and other executive officers, to oversee Seneca Bancorp's compensation and incentive plans, policies and programs, and to oversee Seneca Bancorp's management development and succession plans for executive officers. Seneca Bancorp's Chief Executive Officer will not be present during any committee deliberations or voting with respect to his compensation. The Compensation Committee may form and delegate authority and duties to subcommittees as it deems appropriate.

During the year ended December 31, 2025, the Compensation Committee did not utilize the services of a compensation consultant.

The Compensation Committee operates under a written charter which is available on our website at https://www.senecasavings.com/investor-relations/. This charter sets forth the responsibilities of the Compensation Committee and reflects the Compensation Committee's commitment to create a compensation structure that encourages the achievement of long-range objectives and builds long-term value for our stockholders.

The Compensation Committee considers a number of factors in their decisions regarding executive compensation, including, but not limited to, the level of responsibility and performance of the individual executive officers, the overall performance of Seneca Bancorp and a peer group analysis of compensation paid at institutions of comparable size and complexity. The Compensation Committee also considers the recommendations of the President and Chief Executive Officer with respect to the compensation of executive officers other than the President and Chief Executive Officer.

***Nominating and Corporate Governance Committee.*** The Nominating and Corporate Governance Committee is comprised of Directors Zames, Le Beau, and Hickey each of whom is "independent" in accordance with applicable Nasdaq listing standards. Director Zames serves as chair of the Nominating and Corporate Governance. Our Board of Directors has adopted a written charter for the Nominating and Corporate Governance Committee, which is available on our website at https://www.senecasavings.com/investor-relations/. The Nominating and Corporate Governance met one time during the year ended December 31, 2025. The Board of Directors does not have a formal policy or specific guidelines regarding diversity among board members. However, the Board of Directors seeks members who represent a mix of backgrounds that will reflect the diversity of our stockholders, employees, and customers, and experiences that will enhance the quality of the Board of Directors' deliberations and decisions. As the holding company for a community bank, the Board of Directors also seeks directors who can continue to strengthen Seneca Savings Bank's position in its community and can assist Seneca Savings Bank with business development through business and other community contacts.

The Board of Directors considers the following criteria in evaluating and selecting candidates for nomination:

●  ***Contribution to Board*** – Seneca Bancorp endeavors to maintain a Board of Directors that possesses a wide range of abilities. Thus, the Board of Directors will assess the extent to which the candidate would contribute to the range of talent, skill and expertise appropriate for the Board of Directors. The Board of Directors will also take into consideration the number of public company boards of directors, other than Seneca Bancorp's, and committees thereof, on which the candidate serves. The Board of Directors will consider carefully the time commitments of any candidate who would concurrently serve on the boards of directors of more than one public company other than Seneca Bancorp, it being the policy of Seneca Bancorp to limit public company directorships to one company other than Seneca Bancorp.

●  ***Experience*** – Seneca Bancorp is the holding company for an insured depository institution. Because of the complex and heavily regulated nature of Seneca Bancorp's business, the Board of Directors will consider a candidate's relevant financial, regulatory and business experience and skills, including the candidate's knowledge of the banking and financial services industries, familiarity with the operations of public companies and ability to read and understand fundamental financial statements, as well as real estate and legal experience.

●  ***Familiarity with and Participation in Local Community*** – Seneca Bancorp is a community-orientated organization that serves the needs of local consumers and businesses. In connection with the local character of Seneca Bancorp's business, the Board of Directors will consider a candidate's familiarity with Seneca Bancorp's market area (or a portion thereof), including without limitation the candidate's contacts with and knowledge of local businesses operating in Seneca Bancorp's market area, knowledge of the local real estate markets and real estate professionals, experience with local governments and agencies and political activities, and participation in local business, civic, charitable or religious organizations.

●  ***Integrity*** – Due to the nature of the financial services provided by Seneca Bancorp and its subsidiaries, Seneca Bancorp is in a special position of trust with respect to its customers. Accordingly, the integrity of the Board of Directors is of utmost importance to developing and maintaining customer relationships. In connection with upholding that trust, the Board of Directors will consider a candidate's personal and professional integrity, honesty and reputation, including, without limitation, whether a candidate or any entity controlled by the candidate is or has in the past been subject to any regulatory orders, involved in any regulatory or legal action, or been accused or convicted of a violation of law, even if such issue would not result in disqualification for service under Seneca Bancorp's Bylaws.

●  ***Stockholder Interests and Dedication*** – A basic responsibility of directors is the exercise of their business judgment to act in what they reasonably believe to be in the best long-term interests of Seneca Bancorp and its stockholders. In connection with such obligation, the Board of Directors will consider a candidate's ability to represent the best long-term interests of Seneca Bancorp and its stockholders, including past service with Seneca Bancorp or Seneca Savings Bank and contributions to their operations, the candidate's experience or involvement with other local financial services companies, the potential for conflicts of interests with the candidate's other pursuits, and the candidate's ability to devote sufficient time and energy to diligently perform his or her duties, including the candidate's ability to personally attend board and committee meetings.

●  ***Independence*** – The Board of Directors will consider the absence or presence of material relationships between a candidate and Seneca Bancorp (including those set forth in applicable listing standards) that might impact objectivity and independence of thought and judgment. In addition, the Board of Directors will consider the candidate's ability to serve on any Board committees that are subject to additional regulatory requirements (e.g. Securities and Exchange Commission regulations and applicable listing standards). If Seneca Bancorp should adopt independence standards other than those set forth in the Nasdaq Stock Market listing standards, the Board of Directors will consider the candidate's potential independence under such other standards.

●  ***Additional Factors*** – The Board of Directors will also consider any other factors it deems relevant to a candidate's nomination, including the extent to which the candidate helps the Board of Directors reflect the diversity of Seneca Bancorp's stockholders, employees, customers and communities. The Board of Directors also may consider the current composition and size of the Board of Directors, the balance of management and independent directors, and the need for audit committee expertise.

The committee identifies nominees by first evaluating the current members of the Board of Directors willing to continue in service, including the current members' board and committee meeting attendance and performance, length of board service, experience and contributions, and independence. Current members of the Board of Directors with skills and experience that are relevant to Seneca Bancorp's business and who are willing to continue in service are considered for re-nomination, balancing the value of continuity of service by existing members of the Board of Directors with that of obtaining a new perspective. If there is a vacancy on the Board of Directors because any member of the Board of Directors does not wish to continue in service or if the Board of Directors decides not to re-nominate a member for re-election, the Board of Directors would determine the desired skills and experience of a new nominee (including a review of the skills set forth above), may solicit suggestions for director candidates from all board members and may engage in other search activities.

During the year ended December 31, 2025 we did not pay a fee to any third party to identify or evaluate or assist in identifying or evaluating potential nominees for director.

The Board of Directors may consider qualified candidates for director suggested by our stockholders. Stockholders can suggest qualified candidates for director by writing to our Corporate Secretary at 35 Oswego Street, Baldwinsville, New York 13027. The Board of Directors has adopted a procedure by which stockholders may recommend nominees to the Board of Directors. Stockholders who wish to recommend a nominee must write to Seneca Bancorp's Corporate Secretary and such communication must include:

● A statement that the writer is a stockholder and is proposing a candidate for consideration by the Board of Directors;

● The name and address of the stockholder as they appear on Seneca Bancorp's books, and of the beneficial owner, if any, on whose behalf the nomination is made;

● The class or series and number of shares of Seneca Bancorp's capital stock that are owned beneficially or of record by such stockholder and such beneficial owner;

● A description of all arrangements or understandings between such stockholder and each proposed nominee and any other person or persons (including their names) pursuant to which the nomination(s) are to be made by such stockholder;

● A representation that such stockholder intends to appear in person or by proxy at the meeting to nominate the nominee named in the stockholder's notice;

● The name, age, personal and business address of the candidate, the principal occupation or employment of the candidate and the number of shares of common stock of Seneca Bancorp that are owned by the candidate;

● The candidate's written consent to serve as a director;

● A statement of the candidate's business and educational experience and all other information relating to such person that would indicate such person's qualification to serve on Seneca Bancorp's Board of Directors; and

● Such other information regarding the candidate or the stockholder as would be required to be included in Seneca Bancorp's proxy statement pursuant to Securities and Exchange Commission Regulation 14A.

To be timely, the submission of a candidate for director by a stockholder must be received by the Corporate Secretary at least 120 days prior to the anniversary date of the proxy statement relating to the preceding year's annual meeting of stockholders. If (i) less than 90 days' prior public disclosure of the date of the meeting is given to stockholders and (ii) the date of the annual meeting is advanced more than 30 days prior to or delayed more than 30 days after the anniversary of the preceding year's annual meeting, a stockholder's submission of a candidate shall be timely if delivered or mailed to and received by the Corporate Secretary of Seneca Bancorp no later than the 10<sup>th</sup> day following the day on which public disclosure (by press release issued through a nationally recognized news service, a document filed with the Securities and Exchange Commission, or on a website maintained by Seneca Bancorp) of the date of the annual meeting is first made.

Submissions that are received and that satisfy the above requirements are forwarded to the Board of Directors for further review and consideration, using the same criteria to evaluate the candidate as it uses for evaluating other candidates that it considers.

There is a difference between the recommendations of nominees by stockholders pursuant to this policy and a formal nomination (whether by proxy solicitation or in person at a meeting) by a stockholder. Stockholders have certain rights under applicable law with respect to nominations, and any such nominations must comply with applicable law and provisions of the Bylaws of Seneca Bancorp. See "Stockholder Proposals and Nominations."

#### Transactions With Certain Related Persons
Section 402 of the Sarbanes-Oxley Act of 2002 generally prohibits an issuer from: (1) extending or maintaining credit; (2) arranging for the extension of credit; or (3) renewing an extension of credit in the form of a personal loan for an officer or director. There are several exceptions to this general prohibition, one of which is applicable to Seneca Savings Bank. The Sarbanes-Oxley Act does not apply to loans made by a depository institution that is insured by the Federal Deposit Insurance Corporation and is subject to the insider lending restrictions of the Federal Reserve Act. All loans to Seneca Savings Bank's directors and officers are made in conformity with the Federal Reserve Act and applicable regulations. Federal regulations permit executive officers and directors to receive the same terms that are widely available to other employees as long as the executive officer or director is not given preferential treatment compared to other participating employees. Seneca Savings Bank makes certain loans to its directors, executive officers, employees, and family members of employees (excluding family members of directors, the Chief Executive Officer and the Chief Financial Officer) through an employee loan program pursuant to which loans are made at reduced rates. Specifically, consumer and home equity lines of credit are offered at a reduced rate of 100 basis points below market rates (50 basis points for family members), home equity loans are offered at a reduced rate of 50 basis points below market rates (25 basis points for family members), and mortgage loans are offered at a reduced rate of 25 basis points below market rates (no discount for family members). Since January 1, 2024, there has not been any outstanding loan to any executive officer or director of Seneca Savings Bank that was made at a reduced rate through the employee loan program that exceeded $120,000.

Other than as described above with respect to certain loans made with reduced interest rates, all loans made by Seneca Savings Bank to executive officers, directors, immediate family members of executive officers and directors, or organizations with which executive officers and directors are affiliated, were 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 to persons not related to Seneca Savings Bank, and did not involve more than the normal risk of collectability or present other unfavorable features. The aggregate amount of our loans to our executive officers and directors was $851,000 at December 31, 2025. As of December 31, 2025, these loans were performing according to their original repayment terms.

Pursuant to our Policy and Procedures for Approval of Related Person Transactions, the Audit Committee periodically reviews, no less frequently than twice a year, a summary of transactions in excess of $25,000 with our directors, executive officers, and their family members, for the purpose of determining whether the transactions are within our policies and should be ratified and approved. Additionally, pursuant to our Code of Business Conduct and Ethics, all of our executive officers and directors must disclose any personal or financial interest in any matter that comes before Seneca Bancorp.

Charles Signs, Inc., a business owned by Director Hickey, received from Seneca Savings Bank payments totaling $147,000 and $77,000 during the years ended December 31, 2025 and 2024, respectively, for designing and installing various signs for Seneca Savings Bank.

#### Compensation Plans and Agreements
***Employment Agreements*.** On April 6, 2017, Seneca Savings Bank entered into individual employment agreements with Joseph G. Vitale and Vincent J. Fazio, each of which had an initial term of three years. Each January 1st (the "Renewal Date"), the agreements renew for an additional year, so that the remaining term of agreements will be three years from the Renewal Date. In order for the agreements to renew, the disinterested members of the Board must, at least 30 days prior to the Renewal Date, conduct a comprehensive performance evaluation of each executive for purposes of determining whether to take action regarding the renewal of his employment agreement.

The base salaries established in the employment agreements may be increased, but not decreased (other than a decrease which is applicable to all senior officers). In addition to base salary, each executive will be entitled to participate in any bonus program and benefit plan made available to senior management employees, and will be reimbursed for all reasonable business expenses incurred.

In the event of each executive's involuntary termination of employment for reasons other than cause, disability or death, or in the event of his resignation for "good reason," (a "qualifying termination event"), the executive will receive a lump sum cash severance payment equal to the amount of base salary that he would have earned had he remained employed for the duration of his "benefit period." The benefit period is 12 months or, if greater, the remaining term of his agreement as of the executive's date of termination. In addition, each executive will be entitled to receive life insurance and non-taxable medical and dental insurance coverage substantially comparable to the coverage maintained by Seneca Savings Bank for the benefit period or, if earlier, until the date on which the executive becomes a full-time employee of another employer and receives comparable health and welfare benefits. For purposes of the employment agreements, "good reason" is defined as: (1) a material reduction in base salary or benefits (other than reduction by Seneca Savings Bank that is part of a good faith, overall reduction of such benefits applicable to all employees); (2) a material reduction in the executive's duties or responsibilities; (3) a relocation of the executive's principal place of employment by more than 50 miles from the executive's principal place of employment as of the initial effective date of the employment agreement; or (4) a material breach of the employment agreement by Seneca Savings Bank. In order to be entitled to the severance benefits set forth above, the executive will be required to execute, and not revoke, a release of claims against Seneca Savings Bank related to his employment.

If the executive's qualifying termination event occurs on or after the effective date of a change in control of Seneca Bancorp or Seneca Savings Bank, the executive will be entitled to (in lieu of the payments and benefits described in the previous paragraph) a severance payment equal to three times the executive's highest annual rate of base salary and bonus paid, or earned, during the calendar year of the change in control or either of the two calendar years immediately preceding the change in control. Such payment will be payable in a lump sum within 30 days following the executive's date of termination. In addition, Seneca Savings Bank (or its successor) will continue to provide the executive with life insurance and non-taxable medical and dental insurance coverage substantially comparable to the coverage provided to the executive immediately prior to his date of termination at no cost to the executive. Such continued coverage will cease upon the earlier of: (1) the date which is three years after the executive's date of termination; or (2) the date on which the executive becomes a full-time employee of another employer and receives comparable health and welfare benefits.

In addition, if the executive dies while employed, the executive's estate or beneficiary will be paid his base salary for one year following death, and his family will continue to receive non-taxable medical and dental coverage for one year after his death. The executive will not receive any additional compensation or benefits under his employment agreement in the event he becomes disabled.

Upon termination of employment (other than a termination in connection with a change in control), each executive will be required to adhere to one-year non-competition and non-solicitation covenants.

***Annual Incentive Plan***. Seneca Savings Bank adopted an annual bonus plan effective January 1, 2022 (the "Annual Incentive Plan"). The named executive officers participate in the Annual Incentive Plan, which provides each participant with a bonus opportunity depending on the level of achievement of certain performance objectives established by the compensation committee of Seneca Savings Bank for each individual participant for each year. The specific performance objectives are determined annually by the committee and are subject to change by the committee, but generally include objective performance targets focused on financial performance, profitability, growth, asset quality, and risk management, including, but not limited to, earnings per share, average past due and nonaccrual loans, local deposit growth, net income, return on average assets, return on equity, net loan growth, asset quality, efficiency ratio (including as compared to a peer group) and subjective, discretionary performance targets, such as particular qualitative factors for each participant, based on his or her duties for Seneca Savings Bank. Bonus awards are paid out no later than two and half months following the end of the applicable plan year, provided that the participant remains continuously employed with Seneca Savings Bank through the payment date.

***Supplemental Executive Retirement Agreements***. Seneca Savings Bank entered into individual supplemental executive retirement agreements with Messrs. Vitale and Fazio on June 20, 2016 (the "SERPs"). The SERPs are designed to provide non-qualified supplemental retirement income to Messrs. Vitale and Fazio as an incentive for their continued service with Seneca Savings Bank. The benefits payable under the SERPs described below are funded by the annuity contracts and life insurance policies owned by Seneca Savings Bank with respect to the lives of Messrs. Vitale and Fazio. The SERPs were amended on June 9, 2025.

Under the SERPs, as amended, upon retirement or other separation from service without cause (including due to death or disability) on or after attaining the normal retirement age (which is age 65 for Messrs. Vitale and Fazio), Messrs. Vitale and Fazio (or their beneficiaries) are each entitled to an annual benefit projected to equal to $75,000 and $15,000, respectively, provided the executive commences the benefit on the executive's normal retirement age (as set forth in the SERP). The benefit is payable in equal monthly installments for the executive's life with 15 years guaranteed (the "Normal Retirement Benefit"). In the event of the executive's termination of employment for any reason (other than for cause) on or after his early retirement age (which is age 50 for Mr. Vitale and age 61 for Mr. Fazio) but prior to his normal retirement age, the annual payment under the Normal Retirement Benefit would be reduced to a percentage equal to the accrued liability at the time of the executive's termination over the projected accrued liability as of normal retirement age (the "Early Retirement Benefit"). The Early Retirement Benefit is payable in equal monthly installments for the executive's life with 15 years guaranteed.

In the event of the executive's involuntary termination without cause, voluntary termination for "good reason," death or disability prior to his early retirement age, the executive (or his beneficiary) would be entitled to the amount accrued under the SERP as of the date of termination, as determined in accordance with generally accepted accounting principles (the "Accrued Benefit"). The Accrued Benefit is payable in a cash lump sum within 60 days following the executive's date of termination. If the executive voluntarily resigns without good reason prior to his early retirement age, he would receive no benefit under the SERP.

Notwithstanding the foregoing, upon the executive's termination of employment for any reason (except for cause) following a change in control of Seneca Savings Bank, the executive would be entitled to his Normal Retirement Benefit, regardless of his age on the date of termination, payable in equal monthly installments for life with 15 years guaranteed, commencing on the first day of the month following the executive's date of termination.

Seneca Savings Bank has elected to purchase annuities designed to provide a future source of funds for the lifetime retirement benefits provided under the SERPs. Accordingly, the actual amounts of the SERP benefits are directly based on the amount of the annuity payments set forth in riders attached to the SERPs.

***Executive Split Dollar Agreements***. Seneca Savings Bank has entered into individual Executive Split Dollar Agreements with Messrs. Vitale and Fazio. Under the agreements, each executive's designated beneficiary is entitled to share in the proceeds under a life insurance policy owned by Seneca Savings Bank in the event of the executive's death. If the executive's death occurs while employed with Seneca Savings Bank, the death benefit payable to the executive's designated beneficiary is equal to the lesser of: (1) $300,000 for Mr. Vitale and $200,000 for Mr. Fazio; or (2) the net death benefit (which is the difference between the cash surrender value of the policy and the total proceeds payable under the policy upon the death of the insured). If Mr. Vitale's death occurs after his date of termination (other than for cause) and he has at least 10 years of service with Seneca Savings Bank, the death benefit payable would decrease to the lesser of: (1) $25,000; or (2) the net death benefit (the "Reduced Benefit"). If Mr. Fazio's death occurs after his date of termination (other than for cause) and he has at least seven years of service with Seneca Savings Bank, the death benefit payable would decrease to the Reduced Benefit.

If the executives terminate employment without having met their respective age and years of service requirements described above or terminate employment due to cause, then their designated beneficiaries will not be entitled to any death benefit under their agreements.

***Pension Plan***. Seneca Savings Bank maintains the Pension Plan for Employees of Seneca Savings Bank, a qualified noncontributory defined benefit plan (the "pension plan") for employees. Employees of Seneca Savings Bank hired prior to January 1, 2018 who attained age 21 and completed one year of service are eligible to accrue benefits under the pension plan. Employee hired on or after January 1, 2018 are not eligible to participate in the pension plan.

Contributions to the pension plan are made in order to satisfy the actuarially determined minimum funding requirements according to the Employee Retirement Income Security Act of 1974, as amended ("ERISA"). A participant will become 100% vested in his or her accrued benefit under the plan after five years of service with Seneca Savings Bank.

Upon attainment of the normal retirement date (the later of age 65 or the fifth anniversary of participation in the plan), a participant is entitled to receive the normal retirement benefit, which is an annual benefit calculated by multiplying the participant's average annual compensation up to the integration level by 1.4% for each year of credited service up to 30 years, plus multiplying the participant's average annual compensation in excess of the "integration level" by 1.9% of each year of credited service up to 30 years. The "integration level" for the pension plan is a 35-year average of the taxable wage bases published by the Social Security Administration. If a participant terminates employment prior to his or her normal retirement date, the participant would be entitled to the vested portion of his or her accrued benefit as of the date of termination. The normal form of payment of the normal retirement benefit is a 50% joint and survivor annuity for a married participant or a single life annuity for a participant who is not married. If a participant dies while the participant is still employed by Seneca Savings Bank or if the participant dies after he retires or terminates employment but before benefit payments start, the surviving spouse will be entitled to a life annuity based on the value of the participant's vested accrued benefit.

***Equity Incentive Plan***. Seneca Bancorp has adopted the Seneca Bancorp, Inc. 2019 Equity Incentive Plan (the "Equity Plan"), which was approved by stockholders in 2019. Subject to permitted adjustments for certain corporate transactions, the Plan authorizes the issuance or delivery to participants of up to 131,463 shares of Seneca Bancorp common stock pursuant to grants of incentive and non-qualified stock options, restricted stock awards and restricted stock units. Of this number, the maximum number of shares of Seneca Bancorp common stock that may be issued under the Equity Plan pursuant to the exercise of stock options is 93,903 shares, and the maximum number of shares of Seneca Bancorp common stock that may be issued as restricted stock awards or restricted stock units is 37,560 shares. As of December 31, 2025, there were 4,183 restricted stock awards or units and 33,683 stock options that remain available for future grants under the Equity Plan.

***Employee Stock Ownership Plan.*** The ESOP is a tax-qualified plan that covers substantially all employees, including the named executive officers, who have at least one year of service with Seneca Savings Bank and have attained age 21.

The ESOP trustee holds shares of Seneca Bancorp common stock in a suspense account purchased with the proceeds of a loan from Seneca Bancorp. As the loan is repaid, principally through Seneca Savings Bank's discretionary contributions to the ESOP, over the 25-year term of the loan, the shares are released from collateral as payments on the loan are made and allocated to the accounts of active participants on the basis of each participant's proportional share of plan compensation relative to all participants. Participants vest in their account balances at 20% after two years of service and 20% for each subsequent year of service until fully vested after six years of service. Participants will also become fully vested upon normal retirement, death or disability, a change in control, or termination of the ESOP. Generally, participants will receive distributions from the ESOP upon separation from service in accordance with the terms of the plan document. The ESOP reallocates any unvested forfeited shares among the remaining participants.

***401(k) Plan*.** The Seneca Savings Bank tax-qualified 401(k) plan is maintained for employees, including the named executive officers, who are employed on the first month following their initial date of employment. Eligible employees may make pre-tax contributions to the 401(k) Plan in the form of salary deferrals of up to 100% of their total annual compensation subject to certain IRS limitations.

#### Policies and Practices Related to the Grant of Stock Options
The Compensation Committee and the Board have a historical practice of not granting stock options to executive officers during closed quarterly trading windows as determined under Seneca Bancorp's insider trading policy. Consequently, we have not granted, and do not expect to grant, any stock options to any named executive officers within four business days preceding or one business after the filing with the SEC of any report on Forms 10-K, 10-Q or 8-K that discloses material non-public information. The Compensation Committee and the Board do not take material non-public information into account when determining the timing of equity awards and do not time the disclosure of material non-public information in order to impact the value of executive compensation. We did not grant any stock options to our executive officers, including the named executive officers, during the year ended December 31, 2025.

#### Pay Versus Performance
We are required by the Securities and Exchange Commission (the "SEC") rules to disclose the following information regarding compensation paid to our named executive officers and the relationship between "Compensation Actually Paid," which is calculated in accordance with SEC rules, to our principal executive officer ("PEO") and to our named executive officers other than the PEO ("Non-PEO NEOs") and certain financial performance measures of the Company, including total shareholder return ("TSR") and net income.

The following table sets forth the Compensation Actually Paid to the Company's PEO and the average Compensation Actually Paid to the Company's Non-PEO NEOs for fiscal years 2025 and 2024. In addition, the table provides our cumulative Total Shareholder Return ("TSR") and Net Income.

Non-employee directors each earn an annual retainer of $2,080 and a monthly fee of $1,820 (or $2,276 for the Chairman). Non-employee directors currently receive fees of $275 ($325 for the chair) per meeting for service on the loan, compensation, nominating and corporate governance or ALCO committees and $325 ($375 for the chair) per meeting for service on the audit committee. In addition, each non-employee director serving on the board of directors of Financial Quest, the wholly owned subsidiary of Seneca Savings Bank, receives a per meeting fee of $275 ($325 for the chair). The per meeting fee is reduced by half if the director attends by phone or electronically. Directors LeBeau, Boynton and Hickey serve on the board of directors of Financial Quest.

***Director Deferred Fee Plan.*** On April 19, 2024, Seneca Savings Bank adopted the Seneca Savings Bank Director Deferred Fee Plan which allows directors to defer a portion of their director fees to the account, which is credited with interest at an annual rate equal to one percent above the prime rate reported by the Wall Street Journal as of the first day of the plan year (unless otherwise determined by the board). For 2025, the crediting rate was 8%. The director's account balance will be distributed upon the director's separation from service and will be paid in a lump sum or installments over five, ten, or fifteen year, in accordance with the director's timely election. In the event of a director's death or disability, the account balance shall be paid to the director (or the director's beneficiaries) in a lump sum.

A representative of Bonadio & Co., LLP is expected to attend the annual meeting and may respond to appropriate questions and make a statement if he or she so desires.

Even if the engagement of Bonadio & Co., LLP is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such change would be in the best interests of Seneca Bancorp and its stockholders.

Set forth below is certain information concerning aggregate fees billed for professional services rendered by Bonadio & Co., LLP for the years ended December 31, 2025 and 2024.

***Tax Fees.*** During the years ended December 31, 2025 and 2024, tax fees billed by Bonadio & Co., LLP were $19,000 and $18,000, respectively for tax preparation services.

#### Policy on Audit Committee Pre-Approval of Audit and Non-Audit Services of Independent Registered Public Accounting Firm
The Audit Committee has considered whether the provision of non-audit services, which relate primarily to tax services is compatible with maintaining the independence of Bonadio & Co., LLP. The Audit Committee concluded that performing such services does not affect the independence of Bonadio & Co., LLP in performing its function as our independent registered public accounting firm.

The Audit Committee's current policy is to pre-approve all audit and non-audit services provided by the independent registered public accounting firm, either by approving an engagement prior to the engagement or pursuant to a pre-approval policy with respect to particular services, subject to the *de minimus* exceptions for non-audit services described in Section 10A(i)(1)(B) of the Securities Exchange Act of 1934, as amended. These services may include audit services, audit-related services, tax services and other services. The Audit Committee may delegate pre-approval authority to one or more members of the Audit Committee when expedition of services is necessary. The independent registered public accounting firm and management are required to periodically report to the full Audit Committee regarding the extent of services provided by the independent registered public accounting firm in accordance with this pre-approval, and the fees for the services performed to date. The Audit Committee pre-approved 100% of audit-related and tax fees billed and paid during the year ended December 31, 2025, as indicated in the table above.

The Board of Directors recommends a vote "FOR" the ratification of Bonadio & Co., LLP as independent registered public accounting firm for the year ending December 31, 2026.

#### PROPOSAL III—ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION
The compensation of our Chief Executive Officer and our other most highly compensated executive officers ("NEOs") is described in "PROPOSAL I — Election of Directors – Executive Compensation." Stockholders are urged to read the Executive Compensation section of this Proxy Statement, which discusses our compensation policies and procedures with respect to our NEOs.

In accordance with Dodd-Frank and Section 14A of the Securities Exchange Act of 1934, we are providing Seneca Bancorp stockholders the opportunity to vote on a non-binding, advisory resolution to approve the compensation of our NEOs, which is described in the section titled "PROPOSAL I — Election of Directors – Executive Compensation" in this Proxy Statement. Accordingly, the following resolution will be submitted for a stockholder vote at the 2026 Annual Meeting:

"RESOLVED, that the stockholders of Seneca Bancorp, Inc. (the "Company") approve, on an advisory basis, the overall compensation of the Company's named executive officers, as described in the "PROPOSAL I —Election of Directors—Executive Compensation" section set forth in the Proxy Statement for this Annual Meeting."

This advisory vote, commonly referred to as a "say-on-pay" advisory vote, is non-binding on the Company and the Board. However, the Board values constructive dialogue on executive compensation and other important governance topics with the Company's stockholders and encourage all stockholders to vote their shares on this matter.

Approval of this resolution requires the affirmative vote of a majority of the votes cast at the Annual Meeting. While this vote is required by law, it will neither be binding on the Company or the Board, nor will it create or imply any change in the fiduciary duties of, or impose any additional fiduciary duty on, the Company or the Board. However, the Compensation Committee will take into account the outcome of the vote when considering future executive compensation decisions.

The Board of Directors recommends a vote "FOR" the resolution set forth in Proposal III.

#### PROPOSAL IV—ADVISORY VOTE ON THE FREQUENCY OF FUTURE ADVISORY VOTES ON NAMED EXECUTIVE OFFICER COMPENSATION
Under Dodd-Frank, in addition to providing stockholders with the opportunity to cast an advisory vote on executive compensation, we are required to include in this proxy statement and present at the annual meeting an advisory non-binding stockholder vote on whether an advisory vote on NEO compensation should be held every year, every two years or every three years.

After considering the practices by other companies in this area, the Board and Compensation Committee believe that holding an advisory vote on NEO compensation each year is the optimal interval for conducting and responding to a say on pay vote.

Stockholders have the opportunity to choose among four options (holding the advisory vote on NEO compensation every year, every two years, every three years or abstaining) and, therefore, stockholders will not be voting to approve or disapprove the Board's recommendation.

Although this advisory vote on the frequency of the say on pay vote is advisory and nonbinding, the Board and the Compensation Committee will take into account the outcome of the vote when considering the frequency of future advisory votes on NEO compensation.

The Board of Directors recommends a vote FOR "ONE YEAR" as set forth in Proposal IV.

#### STOCKHOLDER PROPOSALS AND NOMINATIONS
In order to be eligible for inclusion in the proxy materials for our 2027 Annual Meeting of Stockholders, any stockholder proposal to take action at such meeting must be received at Seneca Bancorp's executive office, 35 Oswego Street, Baldwinsville, New York 13027, no later than December 18, 2026, which is 120 days prior to the anniversary of the date we expect to mail these proxy materials. If the date of the 2027 Annual Meeting of Stockholders is changed by more than 30 days, any stockholder proposal must be received at a reasonable time before we print or mail proxy materials for such meeting. Any such proposals shall be subject to the requirements of the proxy rules adopted under the Securities Exchange Act of 1934.

Under SEC Rule 14a-19, a stockholder intending to engage in a director election contest with respect to the Seneca Bancorp annual meeting of stockholders to be held in 2027 must give Seneca Bancorp notice of its intent to solicit proxies by providing the names of its nominees and certain other information at least 60 calendar days before next year's annual meeting. This deadline is March 19, 2027.

In addition to the requirement set forth under SEC Rule 14a-19, Seneca Bancorp's Bylaws provide an advance notice procedure for certain business, or nominations to the Board of Directors, to be brought before an annual meeting of stockholders. In order for a stockholder to properly bring business before an annual meeting, or to propose a nominee to the board of directors, Seneca Bancorp's Secretary must receive written notice not less than 90 days nor more than the 100 days before the anniversary of the prior year's annual meeting of stockholders; provided, however, that in the event the date of the annual meeting is advanced more than 30 days before the anniversary of the preceding year's annual meeting, then, to be timely, notice by the stockholder must be so received no earlier than the day on which public disclosure of the date of such annual meeting is first made and not later than the tenth day following the earlier of the day notice of the meeting was mailed to stockholders or such public disclosure was made.

The notice with respect to stockholder proposals that are not nominations for director must set forth as to each matter such stockholder proposes to bring before the annual meeting: (i) a brief description of the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting; (ii) the name and address of such stockholder as they appear on Seneca Bancorp's books and of the beneficial owner, if any, on whose behalf the proposal is made; (iii) the class or series and number of shares of capital stock of Seneca Bancorp which are owned beneficially or of record by such stockholder and such beneficial owner; (iv) a description of all arrangements or understandings between such stockholder and any other person or persons (including their names) in connection with the proposal of such business by such stockholder and any material interest of such stockholder in such business; and (v) a representation that such stockholder intends to appear in person or by proxy at the annual meeting to bring such business before the meeting.

The notice with respect to director nominations must include: (a) as to each person whom the stockholder proposes to nominate for election as a director, (i) all information relating to such person that would indicate such person's qualification to serve on the Board of Directors of Seneca Bancorp; (ii) an affidavit that such person would not be disqualified under the provisions of Article II, Section 12 of Seneca Bancorp's Bylaws; (iii) such information relating to such person that is required to be disclosed in connection with solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A under the Exchange Act, or any successor rule or regulation; and (iv) a written consent of each proposed nominee to be named as a nominee and to serve as a director if elected; and (b) as to the stockholder giving the notice: (i) the name and address of such stockholder as they appear on Seneca Bancorp's books and of the beneficial owner, if any, on whose behalf the nomination is made; (ii) the class or series and number of shares of capital stock of Seneca Bancorp which are owned beneficially or of record by such stockholder and such beneficial owner; (iii) a description of all arrangements or understandings between such stockholder and each proposed nominee and any other person or persons (including their names) pursuant to which the nomination(s) are to be made by such stockholder; (iv) a representation that such stockholder intends to appear in person or by proxy at the meeting to nominate the persons named in its notice; (v) whether such stockholder intends to solicit proxies in support of director nominees other than Seneca Bancorp's nominees in accordance with the Exchange Act and the rules and regulations promulgated thereunder; and (vi) any other information relating to such stockholder that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for election of directors pursuant to Regulation 14A under the Exchange Act or any successor rule or regulation.

The 2027 annual meeting of stockholders is expected to be held May 18, 2027. Advance written notice for certain business, or nominations to the Board of Directors, to be brought before the next annual meeting must be given to us no earlier than February 7, 2027 and no later than February 17, 2027. If notice is received before February 7, 2027 or after February 17, 2027, it will be considered untimely, and we will not be required to present the matter at the stockholders meeting.

Nothing in this proxy statement shall be deemed to require us to include in our proxy statement and proxy relating to an annual meeting any stockholder proposal that does not meet all of the requirements for inclusion established by the Securities and Exchange Commission in effect at the time such proposal is received.

#### OTHER MATTERS
The Board of Directors is not aware of any business to come before the annual meeting other than the matters described above in the Proxy Statement. However, if any matters should properly come before the annual meeting, it is intended that the Board of Directors, as holders of the proxies, will act as determined by a majority vote.
