Expenses may include the charges and expenses of brokerage houses, nominees, custodians and fiduciaries for forwarding proxies and proxy materials to beneficial owners of shares.

VOTING PROCEDURES

Who Can Vote?

Our Board of Directors has fixed the close of business on March 23, 2026 as the record date for the determination of shareholders entitled to notice of, and to vote at, the Annual Meeting.

On March 23, 2026, there were 7,863,388 shares outstanding.

Quorum

A quorum of shareholders is necessary to hold a valid meeting. If the holders of at least a majority of the total number of our outstanding shares of common stock entitled to vote are represented in person or by proxy at the Annual Meeting, a quorum will exist. We will include proxies marked as abstentions and broker non-votes, as applicable, to determine the number of shares present at the Annual Meeting.

How Many Votes You Have

Each holder of shares of common stock outstanding on March 23, 2026 will be entitled to one vote for each share held of record at the Annual Meeting.

Addresses provided are those listed in the SEC filings as the address of the person authorized to receive notices and communications.

The following table sets forth information about the shares of common stock beneficially owned by each of our directors, each of our named executive officers, and all of our directors and executive officers as a group as of March 23, 2026.

PROPOSAL ONE: ELECTION OF DIRECTORS

The Board of Directors is currently comprised of nine members, and is divided into three classes. Our directors generally serve staggered three-year terms such that usually only one class (approximately one-third of the directors) is elected each year.

Upon the recommendation of the Nominating and Corporate Governance Committee, our Board of Directors has nominated the three individuals listed in the table below for election as directors at the Annual Meeting. If you elect the nominees, they will hold office for the term set forth opposite their names or until their successors have been elected.

As described in a Current Report on Form 8-K filed with the SEC on March 18, 2026, the Company entered into an agreement (the “Agreement”) with Stilwell Activist Fund, L.P., Stilwell Activist Investments, L.P., Stilwell Partners, L.P., Stilwell Value LLC, and Joseph Stilwell (collectively, the “Stilwell Group”) and Dennis Pollack. The Agreement will remain in effect until the completion of the Company’s 2029 Annual Meeting of Shareholders. The Company agreed to nominate and support the election of Mr. Pollack as a director of the Company at the Company’s 2026 Annual Meeting of Shareholders to serve in the class of directors with a term expiring at the Company’s 2029 Annual Meeting of Shareholders. In the event Mr. Pollack is unable to serve as a director of the Company during the term of the Agreement, the Company will appoint a replacement director, selected by the Stilwell Group, subject to the approval of the Company, which approval will not be unreasonably withheld. The Stilwell Group has agreed to reimburse Mr. Pollack for any travel expenses incurred with respect to attending meetings of the Board of Directors.

We know of no reason why any nominee may be unable to serve as a director. If any nominee is unable to serve, your proxy may be voted for another nominee proposed by the Board of Directors. Except for the Agreement or otherwise as indicated herein, there are no arrangements or understandings between the nominees and directors continuing in office and any other person pursuant to which such persons were selected.

Board Responsibilities

The Board of Directors oversees our business and monitors the performance of our management. In accordance with our corporate governance guidelines, the Board of Directors does not involve itself in our day-to-day operations; our executive officers and management oversee our day-to-day operations. Our directors fulfill their duties and responsibilities by attending regular meetings of the Board of Directors and its committees, and also through considerable contact via telephone, e-mail and other communications with the Chairman and others regarding matters of concern and interest to us. Our directors also discuss business and other matters with the Chairman and other key executives.

Meetings of the Board of Directors

The Board of Directors held a total of twelve regular meetings and two special meetings during 2025. Each incumbent director attended at least 75% of the meetings of the Board of

Directors held during the time in which he or she served as director, plus meetings of committees on which that particular director served during this period.

It is our policy that all directors should attend the annual meeting of shareholders. In accordance with such policy, all directors who served at the time of the meeting attended the 2025 Annual Meeting of Shareholders.

COMPENSATION OF DIRECTORS

Director Compensation

Director Compensation Table. The following table sets forth information regarding compensation earned by our non-employee directors during the 2025 fiscal year.

Annual Retainers. We pay annual retainers only to the directors who are not employees of Lake Shore Bank or Lake Shore Bancorp, Inc. We do not pay any meeting fees. For the year ended December 31, 2025, the non-employee directors of Lake Shore Bank and Lake Shore Bancorp, Inc. received the following retainers: (i) annual retainer of $24,800 ($57,300 for the Chairman), (ii) annual retainer of $5,000 for members of Audit and Enterprise Risk committees ($10,000 for

the Chairperson), (iii) annual retainer of $3,000 for members of Nominating and Corporate Governance and Compensation committees ($6,000 for the Chairperson), and (iv) $3,000 for members of the Loan committee (no additional compensation for the Chairperson of the Loan committee). The Chairman of the Board does not earn fees for his service on Board committees. The Director Loan committee was dissolved during the first quarter of 2026.

Effective January 1, 2026, the non-employee directors of Lake Shore Bank and Lake Shore Bancorp, Inc. will receive the following retainers: (1) annual retainer of $32,000 ($64,500 for the Chairman), (ii) annual retainer of $5,000 for members of Audit and Enterprise Risk committees ($10,000 for the Chairperson), (iii) annual retainer of $3,000 for members of Nominating and Corporate Governance and Compensation committees ($6,000 for the Chairperson), and (iv) $3,000 for members of the Executive committee, which was established in 2026 (no additional compensation for the Chairperson of the Executive committee). Additionally, the Chairman of the Board does not earn fees for his service on Board committees.

Supplemental Benefit Plans for Non-Employee Directors. Lake Shore Bank entered into a supplemental benefit plan in 2001, as amended and restated effective November 1, 2015, and subsequently amended on January 20, 2026, with each of its then non-employee directors. The plan provides a supplemental retirement benefit generally determined using a formula equal to a percentage of the participant’s average final pay multiplied by the participant’s years of service, subject to a maximum of 20 years of service or 40% of average final pay. If a currently serving non-employee director remains in service until attaining his or her defined benefit age, the director is automatically credited with 20 years of service and is entitled to receive the full supplemental benefit, regardless of actual years of service completed at that time.

The payment is guaranteed over a period of fifteen years beginning the month following termination of service or age 72, whichever comes first. Currently, each of the non-employee directors participates in the plan, with the exception of Mr. Pollack.

Equity Compensation. Each non-employee director who was in the service of Lake Shore Bancorp, Inc. on February 5, 2025 was granted on March 12, 2025 a number of restricted stock awards in a dollar amount equal to thirty percent (30%) of a non-employee director’s cash fees earned in the prior fiscal year (the “Annual Grants”).

Effective 2026, the structure of the Annual Grants was changed such that each non-employee director is entitled to an annual equity retainer equal to $12,000, which vest in full on the first anniversary of the applicable grant date, subject to the director's continued service.

Equity Plans. Our directors are eligible to participate in the Lake Shore Bancorp, Inc. 2006 Stock Option Plan, the Lake Shore Bancorp, Inc. 2012 Equity Incentive Plan, and the Lake Shore Bancorp, Inc. 2025 Equity Incentive Plan (the “Equity Incentive Plans”). These benefit plans are discussed under the “Information About Our Executive Officers: Compensation Plans - 2006 Stock Option Plan,” “Information About Our Executive Officers: Compensation Plans - 2012 Equity Incentive Plan,” and “Information About Our Executive Officers: Compensation Plans - 2025 Equity Incentive Plan" sections in this proxy statement.

CORPORATE GOVERNANCE

Our Board of Directors has adopted Corporate Governance Guidelines that contain a number of corporate governance initiatives designed to comply with NASDAQ corporate governance listing standards, the Sarbanes-Oxley Act of 2002 and the rules and regulations of the SEC. We have also adopted charters for the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee in order to implement these rules and standards. Current versions of the Audit, Compensation and Nominating and Corporate Governance Committee charters are available on our website, www.mylsbank.com under “About Us”, “Investor Relations” - “Corporate Overview” - "Governance Documents” section. The information set forth on our website shall not be deemed filed with, and is not incorporated by reference into, this proxy statement or any of our other filings under the Securities Act of 1933, as amended, or the Exchange Act of 1934, as amended, except to the extent that we specifically so provide.

Board of Directors Independence

Annually, the Board of Directors determines director independence as defined by NASDAQ listing rule 5605(a)(2). The annual review includes reviewing the relationships that each director, his or her immediate family members and his or her related affiliates had with the Company. In making its determination as to the independence of its directors in accordance with NASDAQ listing standards rules, a review of the outstanding loans that directors Brautigam and Sanvidge and their family members or affiliates had with the Bank was completed, and it was noted that the loans were made in the ordinary course of business with substantially the same terms prevailing for loans made to others unrelated to the Bank and did not involve more than the normal risk of collectability or present other unfavorable features. The Board of Directors made the determination that the above-named directors remained independent. Mr. Kim C. Liddell was not an independent director because he was the President and Chief Executive Officer of the Company in 2025.

The table below notes directors and committee assignments in 2025. As noted in the table below, the Board of Directors is comprised of a majority of directors who qualify as independent according to NASDAQ Stock Market Rules and SEC rules as applicable (including for Audit Committees).

"C" represents Chairperson and "X" represents Member.

(1) Mr. Sanvidge served as a member of the Compensation Committee during the first quarter and part of the second quarter of 2025.

(2) The Director Loan Committee was dissolved in 2026.

Leadership Structure of the Board of Directors

The positions of Chief Executive Officer of the Company and the Chairman of the Board of Directors are expected to continue to be held by two different individuals. The Chairman of the Board is an independent, non-employee director. We believe that this structure provides strength to the Company by giving the Chief Executive Officer a respected voice to our Board, while at the same time giving leadership of the Board to an independent person who, together with the other Directors, provides active oversight of management and its implementation of the strategic plans of the Board. Each of our Directors serves on one or more of the committees of the Board and actively and regularly participates in the various functions of these committees. The committee structure enables the duties of the Board to be divided among the Directors. This division of duties allows each of the Directors to concentrate his or her energies in a focused way on a narrower area of Board responsibility and helps ensure that adequate time is being given to the many oversight responsibilities of the Board. We believe that the size of our Board provides a sufficient number of Directors to serve on each of the Board’s committees, but is not so large as to be cumbersome or excessively expensive to the Company.

Committees of the Board of Directors

Our Board of Directors has established the following committees:

Audit Committee. The Audit Committee oversees and monitors the integrity of the Company’s financial reporting process and systems of internal control regarding finance, accounting and regulatory compliance. The Audit Committee retains, oversees and monitors the independence and performance of the Company’s independent registered public accounting firm. The Audit Committee also oversees and monitors the independence and performance of the internal audit department and acts as an avenue of communication between the independent registered public accounting firm, management, the internal audit department and the Board of Directors. The Audit Committee meets with the external auditors to review quarterly and annual SEC filings, the results of the annual audit and other related matters.

Our Board of Directors determined that Ms. Segarra qualified as an "audit committee financial expert" as defined in Item 407(d)(5) of Regulation S-K. The Audit Committee chose Ms. Segarra to serve as the “financial expert” on behalf of the Company for 2025. The Audit Committee met eight times during 2025.

Compensation Committee. The Compensation Committee evaluates the performance of our management team and recommends compensation based upon that performance. It oversees executive compensation and director compensation by approving salary increases and reviewing general personnel matters such as named executive officer performance evaluations. The Compensation Committee annually reviews and makes recommendations to the Board of Directors with respect to the compensation of directors and named executive officers. It is also responsible for approving, evaluating and administering compensation structure, policies and programs, which includes benefit plans, such as the Company’s 401(k) and ESOP plan, as well as incentive plans and stock compensation plans.

In 2025, the Company engaged Pearl Meyer to provide advice and analysis regarding executive compensation matters, including market benchmarking, program design, and best practices for executive and director compensation. Pearl Meyer's engagement was considered to

be independent and did not present any conflicts of interest.

The Compensation Committee takes into account numerous factors when determining a recommendation for the salaries and incentive goals of named executive officers. In addition to information obtained from the American Bankers Compensation and Benefits survey and information provided from other relevant third party sources, the Compensation Committee also obtains the Chief Executive Officer’s recommendation for proposed salary increases and incentive goals for the named executive officers (other than the President and Chief Executive Officer). The results of the non-binding shareholder vote to approve the compensation of the Company’s named executive officers from the most recent shareholders’ meeting are also reviewed by the Compensation Committee. The Compensation Committee considers the Company's performance in the prior year, the Company's strategic plans and goals for the future, and position scope (for positions other than the President and Chief Executive Officer) as part of its decision process to decide upon a recommendation for salaries and incentive goals for the named executive officers.

The Compensation Committee makes recommendations on compensation for named executive officers and directors which is subject to full Board of Director approval. The Compensation Committee met five times during 2025.

Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee recommends the nomination of directors to the full Board of Directors to fill the terms for the upcoming year or to fill vacancies during a term. The Nominating and Corporate Governance Committee considers recommendations from shareholders if submitted in a timely manner in accordance with the procedures established by the Committee and applies the same criteria to all persons being considered. The Nominating and Corporate Governance Committee also assists the Board of Directors in monitoring a process to assess Board of Directors’ effectiveness and in developing and implementing our corporate governance guidelines and reviewing and approving all transactions with affiliated parties. The Nominating and Corporate Governance Committee monitors our regulatory compliance and our compliance with our corporate governance guidelines. In addition, the Nominating and Corporate Governance Committee recommends to the full Board the assignment of Directors to the committees of the Board, which responsibility includes a determination of the independence of individual directors according to the NASDAQ and SEC rules. The Nominating and Corporate Governance Committee also oversees periodic evaluations of individual Directors and of the full Board of Directors, to insure their effectiveness. Lastly, the Nominating and Governance Committee assists the Board of Directors in selecting a President and Chief Executive Officer and in selecting a chairperson for the Board of Directors by overseeing the succession process for these positions. The Committee also ensures that an emergency succession plan for the Chief Executive Officer is in place and is annually updated.

The Nominating and Corporate Governance Committee met five times during 2025.

The Nominating and Corporate Governance Committee has adopted procedures for the submission of recommendations for director nominees by our shareholders. If a determination is made that an additional candidate is needed for the Board of Directors, the Nominating and Corporate Governance Committee will consider candidates submitted by our shareholders. Shareholders can submit the names of qualified candidates for director by writing to the chairperson of the Nominating and Corporate Governance Committee at 31 East Fourth Street,

Dunkirk, New York 14048. The chairperson must receive a submission not less than 180 days prior to the anniversary date of our proxy materials for the preceding year’s annual meeting. The submission must include the following information:

A nomination submitted by a shareholder for presentation by the shareholder at an annual meeting of shareholders must comply with the procedural and informational requirements described in our bylaws.

Shareholder nominees are analyzed by the Committee in the same manner as nominees that are identified by the Committee. We do not pay a fee to any third party to identify or evaluate nominees. As of April 7, 2026, the Committee had not received any shareholder recommendations for nominees in connection with the Annual Meeting that remained outstanding.

Consideration of Director Candidates

It is the policy of the Nominating and Corporate Governance Committee to select individuals as director nominees with the goal of creating a balance of knowledge, experience and interest on the Board. The Committee evaluates candidates for their character, judgment, business experience and acumen, including the director qualifications set forth in the Company's bylaws.

The Nominating and Corporate Governance Committee considers the following skills and characteristics when deciding which individuals to nominate for election as director:

The Nominating and Corporate Governance Committee does not assign specific weights to particular criteria and no particular criterion is necessarily applicable to all prospective director candidates. For a discussion of the specific backgrounds and qualifications of our current directors and director nominees, see “Information about our Board of Directors – Business Experience of Directors.”

Risk Oversight by the Board of Directors

The Board of Directors is responsible for the oversight of risks that could have a material effect on the Company. This oversight is conducted primarily by the Enterprise Risk Committee, with the assistance of other committees of the Board. The Enterprise Risk Committee oversees and monitors the Bank’s enterprise risk management program. A key role of the Enterprise Risk Committee is to coordinate with Management, Board Committees and the Board of Directors to ensure all parties accountable for risk understand the risks to the institution and confirm that risks are identified, measured, monitored and controlled. The Board of Directors satisfies this responsibility through full reports by each committee chairperson regarding the committee’s considerations and actions, as well as through regular reports directly from members of management who are responsible for oversight of particular risks within the Company, including credit, interest rate, liquidity, price, strategic, reputational, operational, information technology (including cybersecurity), and compliance.

Compensation Plans and Agreements

Employment Agreements. Lake Shore Bank entered into an employment agreement with Mr. Liddell on December 16, 2024, as amended on January 20, 2026, and entered into an employment agreement with Mr. Gilden on March 11, 2025, as amended on January 20, 2026 (together, the “Employment Agreements”). Commencing on January 20, 2027 and continuing each anniversary thereafter, the term of the Employment Agreements will automatically extend for an additional year, so that the term again becomes three years unless the Board of Directors gives either executive a written notice of non-renewal. If the Board of Directors gives either executive a written notice of non-renewal, such employment agreement will remain in effect until the remaining term expires, unless the parties agree that the term will end on an earlier date. Notwithstanding the foregoing and regardless of any non-renewal notice, the Employment Agreements will remain in effect for a period of thirty-six (36) months following the effective date of a change in control if a change in control occurs during the term of the Employment Agreements.

The Employment Agreements provide that Messrs. Liddell and Gilden will receive an annual base salary of $550,000 and $265,000 during the term of the Employment Agreement and the base salary may be increased. Messrs. Liddell and Gilden’s current base salaries are $635,250 and $291,500, respectively. In addition to base salary, Messrs. Liddell and Gilden will be eligible to receive an annual performance-based cash bonus, depending on the achievement of certain performance metrics, and, at the discretion of the compensation committee of the board of directors, Messrs. Liddell and Gilden will be eligible to receive long-term incentive compensation. Mr. Liddell will also be entitled to an annual executive perquisites allotment as approved by the Board of Directors of Lake Shore Bank.

In the event Mr. Liddell or Mr. Gilden voluntarily terminates employment without “good reason,” (as defined in the Employment Agreements) the executive will be entitled to receive the sum of his (i) unpaid base salary, (ii) unpaid expense reimbursements, (iii) unused accrued paid time off and (iv) earned but unpaid incentive compensation (together, the “Accrued Benefits”).

In the event Mr. Liddell or Mr. Gilden’s employment involuntarily terminates for a reason other than cause or in the event of his resignation for “good reason,” the executive will receive a lump sum severance payment in an amount equal to the Accrued Benefits plus one times base salary and the average annual incentive cash compensation awarded with respect to the three most recent fiscal years ending before the year of termination provided that the executive timely executes a release agreement. In addition, the executive will receive a cash lump sum payment in an amount equal to Lake Shore Bank’s cost of otherwise continuing life, medical and dental coverage for the executive for twelve (12) months.

In the event Mr. Liddell or Mr. Gilden’s employment involuntarily terminates for a reason other than cause or in the event of his resignation for “good reason,” in either event within three months before or twelve (12) months following a change in control, the executive will receive a severance payment, paid in a single lump sum, equal to the executive’s Accrued Benefits plus three times the sum of (i) his base salary in effect as of the date of termination or immediately before the change in control, whichever is higher, and (ii) the highest annual cash bonus (the average annual cash bonus for Mr. Gilden) earned with respect to the three most recent fiscal years ending before the year of the change in control. In addition, the executive will receive a cash lump sum payment in an amount equal to the cost of continuing life, medical and dental coverage for the executive for thirty-six (36) months. The executive will also be entitled to receive a gross-up

payment for any excise taxes imposed under Sections 280G and 4999 of the Internal Revenue Code.

Upon termination of Mr. Liddell or Mr. Gilden’s employment (other than following a change in control), the executive will be subject to certain restrictions on his ability to compete or to solicit business or employees of the Bank and the Company for a period of one year. The Employment Agreements also include provisions protecting the Company’s and the Bank’s confidential business information.

Annual Incentive Plan. We provide performance-based bonuses to our named executive officers pursuant to the Annual Incentive Plan, which is designed to link awards to our strategic and operating objectives. The goal of the plan is to have long-term viability and to be attractive to new hires and help retain current employees. The plan measures business plan goals and objectives and clearly defines these for the calendar year for which the plan is in effect. For purposes of the annual bonus, each named executive officer is evaluated on several corporate performance measures which are established at the beginning of the year and relate to strategic business objectives for the ensuing year. The named executive officers, with the exception of the President and Chief Executive Officer, are also evaluated on individual performance measures that take into account individual responsibilities, in addition to the corporate performance measures. The Compensation Committee establishes the performance measures for each of the named executive officers. The President and Chief Executive Officer is not involved in decisions regarding his performance-based bonus. Decisions relating to the President and Chief Executive Officer’s performance-based compensation are determined and recommended by the Compensation Committee. The Compensation Committee presents the performance measures to the Board of Directors for approval.

Supplemental Executive Retirement Plans. Lake Shore Bank entered into a supplemental executive retirement plan with Kim C. Liddell, President, CEO, and Director, of the Company and the Bank on December 16, 2024, which replaced the prior supplemental executive retirement plan that Lake Shore Bank and Mr. Liddell entered into on July 16, 2024. Under the plan, if Mr. Liddell terminates employment on or after age 67, Lake Shore Bank will pay Mr. Liddell the annual amount that is paid from Annuity Contracts (as defined in the plan), with such annual amount payable in 12 equal monthly installments for 15 years, and if the executive is living at the end of the 15 year payment period, such payments will continue for the remainder of Mr. Liddell’s life. If Mr. Liddell terminates employment before age 67, Lake Shore Bank will pay Mr. Liddell an amount equal to the amount that is paid from the Annuity Contracts, with such annual amount payable in twelve (12) equal monthly installments for fifteen (15) years, and if the executive is living at the end of the fifteen (15) year payment period, such payments will continue for the remainder of the executive’s life. The plan also provides a benefit in the event of Mr. Liddell’s disability, death, or upon the occurrence of a change in control followed by a qualifying termination of employment.

Lake Shore Bank entered into a supplemental benefit plan with Jeffrey M. Werdein, Executive Vice President, Commercial Division, of the Company and the Bank. Under the supplemental benefit plan, Mr. Werdein is fully vested in an annual benefit, payable in monthly installments, and the annual benefit is equal to (i) 2% of the officer’s average final pay (which is defined as the average pay over the two years prior to termination of service), multiplied by (ii)

the officer’s years of service (with a maximum percentage of 40% of average final pay). The benefit amount is payable over a period of fifteen years commencing at age 65, and in the event of a change of control, the executive is treated as having attained age 65 for purposes of benefit payments.

Retention Agreement. In order to provide further incentive for Jeffrey M. Werdein, Executive Vice President Commercial Division of the Company and the Bank, to remain in the employ of Lake Shore Bank, Lake Shore Bank entered into a retention agreement with Mr. Werdein on March 29, 2018. Under the agreement, Mr. Werdein will receive a total of $1.4 million provided that he remains continuously employed with Lake Shore Bank through March 29, 2028, payable in three equal installments on March 29, 2028, January 2, 2029 and January 2, 2030. In the event Mr. Werdein’s employment is terminated without cause, for good reason or due to death or disability prior to March 29, 2028, Mr. Werdein will receive the vested account balance as set forth in the agreement. If Mr. Werdein’s employment is terminated within two years of a change of control and prior to March 29, 2028, Mr. Werdein may receive up to $1.4 million in a lump sum.

Employee Stock Ownership Plan. This plan is a tax-qualified plan that covers substantially all employees who have at least one year of service with the Bank and have attained age 21. The Company loaned the Employee Stock Ownership Plan Trust sufficient funds to purchase 322,354 shares in connection with the Company's initial public offering in 2006 (the "2006 Loan"). In connection with the 2025 stock offering, the ESOP purchased an additional 396,036 shares of Company common stock, which increased the total amount of unallocated shares to 514,296. The ESOP funded its stock purchase with a loan from the Company equal to the aggregate purchase price of the common stock and the outstanding balance of the 2006 Loan (the 2006 Loan was refinanced into the new ESOP loan).

Although contributions to the plan are discretionary, the Bank intends to contribute enough money each year to make the required principal and interest payments on the loan from the Company. This loan is for a term of 25 years and calls for annual payments of principal and interest. The plan pledges the shares it purchases as collateral for the loan and holds them in a suspense account.

The plan will not distribute the pledged shares right away. Instead, it will release a portion of the pledged shares annually. Assuming the plan repays its loan as scheduled over a 25-year term, we expect that 1/25th of the shares will be released annually in years 2025 through 2049. Although the repayment period of the loan is scheduled over a 25-year term, we may prepay a portion of the principal which would trigger the release of additional shares. The plan will allocate the shares released each year among the accounts of participants in proportion to their eligible compensation for the year. Participants direct the voting of shares allocated to their accounts. Shares in the suspense account and allocated shares for which no voting instructions are received will be voted in a way that mirrors the votes which participants cast.

401(k) Defined Contribution Plan. The Lake Shore Bank tax-qualified 401(k) defined contribution plan is maintained for employees who are employed on the first month following their initial date of employment and attained age 21. Eligible employees may make pre-tax contributions to the 401(k) Plan in the form of salary deferrals of up to 75% of their total annual compensation

subject to certain IRS limitations. The plan consists of three components: 401(k), Profit Sharing, and Safe Harbor. For the 401(k) component, the Bank makes a matching contribution equal to 40% of the eligible employee’s salary deferral, up to 6% of such employee’s compensation, once an employee is eligible to participate in the 401(k) plan. For the profit sharing component, the Bank makes a discretionary contribution, up to 5.1% of an eligible employee’s salary, depending on years of service. Lastly, the Bank contributes 3.4% of an eligible employee’s salary based on years of service, which is a discretionary contribution to the Safe Harbor component of the plan.

2025 Equity Incentive Plan. The Lake Shore Bancorp, Inc. 2025 Equity Incentive Plan provides for the grant of stock options, restricted stock awards, and restricted stock units to its officers, employees, and directors. The 2025 Equity Incentive Plan is administered by the members of the Company’s Compensation Committee and up to 406,470 shares of Company common stock are authorized for issuance pursuant to grants of stock options, restricted stock awards and restricted stock units. For employees, the sum of the grant date fair value of equity awards, including stock options, restricted stock and restricted stock units, may not exceed $500,000 for any calendar year. As of March 23, 2026, 286,349 shares remain available for grant under the 2025 Equity Incentive Plan.

2012 Equity Incentive Plan. Equity awards can no longer be granted under the 2012 Equity Incentive Plan since the plan was adopted more than 10 years ago. Restricted stock awards and stock options previously granted under this plan remain outstanding and are subject to the terms and conditions of this plan.

2006 Stock Option Plan. Stock options can no longer be granted under the Lake Shore Bancorp, Inc. 2006 Stock Option Plan since the plan was adopted more than 10 years ago. Stock options previously granted under this plan remain outstanding and are subject to the terms and conditions of this plan.

PROPOSAL TWO: APPROVE, ON AN ADVISORY BASIS, A NON-BINDING RESOLUTION REGARDING THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

Pursuant to Section 951 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), the proxy rules of the SEC were amended to require that not less frequently than once every three years, a proxy statement for an annual meeting of shareholders must include a separate resolution subject to a non-binding shareholder vote to approve the compensation of the Company’s named executive officers disclosed in the proxy statement.

The executive officers named in the summary compensation table and disclosures set forth below under the “Executive Officer Compensation” section in this proxy statement and deemed to be “named executive officers” are Mr. Liddell, Mr. Werdein, and Mr. Gilden.

This proposal gives shareholders the ability to vote on the compensation of our named executive officers through the following resolution:

“Resolved, that the shareholders approve, on an advisory basis, the compensation of the named executive officers as disclosed in the “Executive Officer Compensation” section of the proxy statement.”

The shareholder vote on this proposal is not binding on Lake Shore Bancorp, Inc. or the Board of Directors and cannot be construed as overruling any decision made by the Board of Directors. However, the Board of Directors of Lake Shore Bancorp, Inc. will review the voting results on the non-binding resolution and take them into consideration when making future decisions regarding executive compensation.

the board of directors unanimously recommends a vote “for” the non-binding resolution to approve the compensation of our named executive officers.

The discussion provided below reflects the SEC’s executive compensation reporting requirements for “smaller reporting companies.”

Summary Compensation Table

The following table provides the total compensation paid to or earned by the named executive officers for fiscal years ended December 31, 2025 and 2024. Each individual listed in the table below is referred to as a named executive officer or NEO.

Outstanding Equity Awards at Fiscal Year End

Relationship Disclosure

Equity Compensation Plan Information

The following table presents certain information regarding our Equity Compensation Plans in effect as of December 31, 2025 (the 2006 Stock Option Plan, the 2012 Equity Incentive Plan, and the 2025 Equity Incentive Plan).

PROPOSAL THREE: CHOOSE THE FREQUENCY OF THE ADVISORY VOTE ON THE NON-BINDING RESOLUTION TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

Section 951 of the Dodd-Frank Act amended the proxy rules of the SEC to require that not less frequently than once every six years, a proxy statement for an annual meeting of shareholders must include a separate non-binding proposal subject to a shareholder vote to determine whether the shareholder vote to approve the compensation of the named executive officers will occur every one, two or three years.

Accordingly, we are seeking a shareholder vote regarding whether the non-binding resolution to approve the compensation of our named executive officers should occur every year, every two years or every three years.

The Board of Directors asks that you support a frequency of every year for future non-binding resolutions on compensation of our named executive officers. The determination was based upon the premise that named executive officer compensation is evaluated, adjusted and approved on an annual basis by the Board of Directors upon a recommendation from the Compensation Committee and the belief that investor sentiment should be a factor taken into consideration by the Compensation Committee in making its annual recommendation.

The advisory vote on this proposal is not binding on Lake Shore Bancorp, Inc. or the Board of Directors and cannot be construed as overruling any decision made by the Board of Directors. However, the Board of Directors of Lake Shore Bancorp, Inc. will review the results of the advisory vote and take them into consideration when making future decisions regarding the frequency of submitting to shareholders the non-binding resolution to approve the compensation of our named executive officers.

the board of directors unanimously recommends an Advisory vote for a frequency of “Annual basis” for future non-binding resolutions to approve the compensation of our named executive officers.

Audit Committee Pre-Approval Policy

Consistent with SEC and Public Company Accounting Oversight Board requirements regarding auditor independence, the Audit Committee has responsibility for appointing, setting compensation and overseeing the work of our independent registered public accounting firm. In recognition of this responsibility, the Audit Committee has established a policy regarding pre-approval of all audit and permissible non-audit services provided by the independent registered public accounting firm.

Pre-approval of Services. The Audit Committee shall pre-approve all auditing services and permitted non-audit services (including the fees and terms) to be performed for us by our independent registered public accounting firm, subject to the de minimis exception for non-audit services described below which, if not pre-approved, are approved by the Audit Committee prior to completion of the audit.

Exception. The pre-approval requirement set forth above, shall not be applicable with respect to non-audit services if:

During the year ended December 31, 2025, the Audit Committee pre-approved the services performed by our independent registered public accounting firm in accordance with their policy. The de minimis exception (as defined in Rule 202 of the Sarbanes-Oxley Act) was not applied to any of the 2025 total fees.

Delegation. The Audit Committee may delegate to one or more designated members of the Audit Committee the authority to grant required pre-approvals. The decisions of any member to whom authority is delegated under this paragraph to pre-approve activities under this subsection shall be presented to the full committee at its next scheduled meeting.

AUDIT COMMITTEE REPORT

On March 17, 2026, the Audit Committee of the Board of Directors reviewed and discussed with management the audited consolidated financial statements dated December 31, 2025. The Audit Committee also discussed with Yount, Hyde & Barbour, P.C., the independent registered public accounting firm of the Company, the matters required to be discussed with those charged with governance pursuant to the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the Securities and Exchange Commission.

The Audit Committee has received from Yount, Hyde & Barbour, P.C., the written disclosure and the letter required by applicable requirements of the PCAOB regarding Yount, Hyde & Barbour’s communications with the Audit Committee concerning independence and has discussed Yount, Hyde & Barbour’s independence with its representatives. These items relate to that firm’s independence from the Company.

Based on its review and discussions referred to above, the Committee has recommended to the Board of Directors that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 for filing with the Securities and Exchange Commission.

This foregoing audit committee report is not “soliciting material,” is not deemed “filed” with the SEC, and shall not be deemed incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filing of ours under the Securities Act of 1933, as amended, or under the Securities Exchange Act of 1934, as amended, except to the extent we specifically incorporate this report by reference.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE AND
TRANSACTIONS WITH RELATED PERSONS

Delinquent Section 16(a) Reports

Section 16(a) of the Securities Exchange Act of 1934 requires our directors and executive officers, and persons who own more than 10% of our common stock, to report to the SEC their initial ownership of our common stock and any subsequent changes in that ownership. We are required to disclose in this proxy statement any late filings or failures to file.

To our knowledge, based solely on our review of the copies of such reports furnished to us and written representations that no other reports were required during the year ended December 31, 2025, we believe that all Section 16(a) filing requirements applicable to our executive officers and directors during 2025 were met except that Director Sharon E. Brautigam, Director Michelle M. DeBergalis, Director John P. McGrath, Director Jack L. Mehltretter, Director Ronald J. Passafaro, Director Kevin M. Sanvidge, and Director Ann M. Segarra each filed a late Form 4 to report the receipt of equity awards.

Transactions with Related Persons

Lake Shore Bank has outstanding loans to its directors, executive officers and their related interests. These loans: (1) were made in the ordinary course of business; (2) were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with persons not related to Lake Shore Bank; and (3) did not involve more than the normal risk of collectability or present other unfavorable features.

It is the written policy of our Board of Directors that a majority of the disinterested members of the entire Board of Directors must approve in advance any extension of credit to any executive officer, director, or principal shareholder and their related interests if the aggregate of all extensions of credit to that insider and his or her related interests exceeds the greater of $25,000 or 5% of Lake Shore Bank's unimpaired capital and surplus, whichever is greater. The interested party may not participate either directly or indirectly in the voting on such an extension of credit. Prior approval is required, however, for any and all extensions of credit to any insider if the aggregate of all other extensions to that person and their related interests exceeds $500,000, regardless of its percentage of capital.

In addition, pursuant to our Code of Conduct and Ethics, if an officer or director has an interest in a matter or transaction before the Board of Directors, such individual must disclose to the Board of Directors all material non-privileged information relevant to the Board of Directors’ decision on the matter or transaction, including: (1) the existence, nature and extent of their interest; and (2) the facts known to the individual as to the matter or transaction under consideration. The individual must also refrain from participating in the discussion of the matter or transaction and may not vote on the matter or transaction. In addition to approval by the Board of Directors, such transactions and matters must also be approved by the Nominating and Corporate Governance Committee.

In addition to the requirement set forth under SEC Rule 14a-19, Lake Shore 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 shareholders. In order for a shareholder to properly bring business before an annual meeting, or to propose a nominee to the Board of Directors, Lake Shore 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 shareholders; 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 shareholder 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 shareholders or such public disclosure was made.

The notice with respect to shareholder proposals that are not nominations for director must set forth as to each matter such shareholder 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 shareholder as they appear on Lake Shore 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 Lake Shore Bancorp which are owned beneficially or of record by such shareholder and such beneficial owner; (iv) a description of all arrangements or understandings between such shareholder and any other person or persons (including their names) in connection with the proposal of such business by such shareholder and any material interest of such shareholder in such business; and (v) a representation that such shareholder 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 shareholder 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 Lake Shore Bancorp; (ii) an affidavit that such person would not be disqualified under the provisions of Article II, Section 12 of Lake Shore 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 Securities Exchange Act of 1934, as amended (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 shareholder giving the notice: (i) the name and address of such shareholder as they appear on Lake Shore 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 Lake Shore Bancorp which are owned beneficially or of record by such shareholder and such beneficial owner; (iii) a description of all arrangements or understandings between such shareholder 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 shareholder; (iv) a representation that such shareholder intends to appear in person or by proxy at the meeting to nominate the persons named in its notice; (v) whether such shareholder intends to solicit proxies in support of director nominees other than Lake Shore Bancorp’s nominees in accordance with the Exchange Act and the rules and regulations promulgated thereunder; and (vi) any other information relating to such shareholder 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 shareholders is expected to be held on May 19, 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 8, 2027 and no later than February 18, 2027. If notice is received before February 8, 2027 or after February 18, 2027, it will be considered untimely, and we will not be required to present the matter at the shareholders 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 shareholder 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.

To assure that your shares are represented at the Annual Meeting, please vote your shares promptly over the Internet, by phone or on a paper proxy card if you request one.
