We are pleased to invite you to attend the 2026 Annual Meeting of Stockholders of Latham Group, Inc. to be held on Thursday, April 30, 2026, at 8:00 a.m. Eastern Daylight Time at The Adelphi Hotel, 365 Broadway, Saratoga Springs, NY 12866.

In 2025, we continued to outperform the U.S. in-ground pool market, growing our net sales by 7.4% year-over-year, and succeeded in expanding margins despite a market for U.S. in-ground pool starts that we estimate declined by low- to mid-single digits. We made investments that have positioned the Company for sales growth and accelerated profitability in 2025 and beyond. We also began to realize benefits from investments in our strategy to expand Latham’s presence in the Sand States.

Our industry outperformance was driven by continued fiberglass share gains and increased awareness and adoption of automatic safety covers. As consumers continued to recognize the speed of installation, eco-friendly and cost savings advantages of fiberglass pools, this product category represented 76.5% of Latham’s total in-ground pool sales in 2025, demonstrating increased market penetration. We concluded 2025 with net sales of $545.9 million, net income of $11.1 million and Adjusted EBITDA of $99.8 million. Our lean manufacturing and value engineering initiatives, along with accretive acquisitions of Coverstar Central in August 2024 and Coverstar New York and Tennessee in early 2025 enabled gross margin expansion of 320 basis points for the year.

As an indicator of strong progress in the Company’s strategy to expand its presence in the important Sand States, we saw double digit growth in fiberglass pool sales in Florida, our initial target market. We are now represented in several Master Planned Communities in Florida, and have continued to nurture strategic partnerships with select custom homebuilders.

Due in large measure to our lean manufacturing and value engineering initiatives, we saw gross margin and Adjusted EBITDA margin expansion in 2025. We concluded 2025 with a cash balance of $71.0 million, providing us with substantial financial flexibility to grow our business.

In 2026, we will continue to execute on our key strategic priorities, namely, to drive increased awareness and adoption of fiberglass pools and autocovers to continue to significantly outperform the U.S. in-ground pool market. We plan to expand and refine our branding and marketing spend in 2026, with increased focus on building out our presence in the important Sand State markets through greater contractor and homebuilder engagement. We enter 2026 in a strong competitive position. Under similar industry conditions to 2025, we believe our leadership in the growing fiberglass pool category, our expanding automatic safety cover business, growth opportunities in the Sand States and our improved cost structure should support another year of market outperformance.

On behalf of our Board of Directors and the entire Latham team, thank you for your continued support.

Details regarding the business to be conducted at the 2026 Annual Meeting of Stockholders and admission thereto are described in the accompanying Notice of Annual Meeting of Stockholders and proxy statement.

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE ANNUAL MEETING OF STOCKHOLDERS TO BE HELD ON APRIL 30, 2026

The Notice of the 2026 Annual Meeting, the accompanying proxy statement for the 2026 Annual Meeting and our annual report to stockholders for the fiscal year ended December 31, 2025 are available at www.proxyvote.com.

In this proxy statement, unless otherwise indicated or the context otherwise requires, references to the “Company,” “Latham,” “we,” “us” and “our” refer to Latham Group, Inc. Latham Group, Inc. is a holding company that does not conduct any business operations and therefore references to our operations and financial performance include Latham Group, Inc. and its consolidated subsidiaries.

This proxy statement is furnished to stockholders of Latham Group, Inc., a Delaware corporation (the “Company”), in connection with the solicitation of proxies by our board of directors (our “Board”) for use at our 2026 Annual Meeting of Stockholders to be held on Thursday, April 30, 2026 (the “Annual Meeting”), and at any adjournment or postponement thereof.

We are making this proxy statement and our annual report to stockholders for the fiscal year ended December 31, 2025 (the “Annual Report”) available to our stockholders electronically via the Internet at www.proxyvote.com. On or about March 20, 2026, we mailed to our stockholders a Notice of Internet Availability of Proxy Materials (the “Internet Notice”) containing instructions on how to access this proxy statement and vote online or by telephone.

This proxy summary highlights information contained elsewhere in this proxy statement for our Annual Meeting. This proxy summary does not contain all of the information that you should consider, and you should read the entire proxy statement before voting. For more complete information regarding the 2025 operational and financial performance of Latham, you should review our Annual Report.

Latham Group, Inc., headquartered in Latham, New York, is the largest designer, manufacturer and marketer of in-ground residential swimming pools in North America, Australia, and New Zealand. With an operating history that spans over 65 years, we offer the industry’s broadest portfolio of pools and related products, including fiberglass pools, packaged pools, pool liners and automatic and winter safety pool covers. We hold the #1 position in North America in every product category in which we compete. We believe that we are the most sought-after brand in the pool industry and the only pool company that has established a direct relationship with the homeowner. We are Latham, The Pool Company™.

We have a heritage of innovation. In an industry that has traditionally marketed on a business-to-business basis (pool manufacturer to dealer), we pioneered the first “direct-to-homeowner” digital and social marketing strategy that has transformed the homeowner’s purchase journey. Through this marketing strategy, we are able to create demand for our pools and generate and provide high quality, purchase-ready consumer leads to our dealer partners.

Partnership with our dealers is integral to our collective success, and we have enjoyed long-tenured relationships averaging over 15 years. We support our dealer network with business development tools, co-branded marketing programs and in-house training, as well as an operations platform consisting of approximately 1,804 full-time employees across approximately 30 locations as of December 31, 2025. The full resources of the Company are dedicated to designing and manufacturing high-quality pool products with the homeowner in mind, and positioning ourselves as a value-added partner to our dealers.

Our Board currently consists of nine directors. Following a review of the individual and aggregate qualifications, attributes, skills and experience of Board members, our Board has re-nominated the three Class II directors for election at our Annual Meeting. Our Board believes that the director nominees will continue to collectively serve in the best interests of stockholders and the Company and assist our Board to fulfill its significant oversight role.

Each of the Class II director nominees will serve a three-year term and until a successor has been duly elected and qualified, or until such director’s earlier resignation, retirement or other termination of service.

The following table sets forth a summary of key qualifications, attributes, skills and experience that our current directors contribute to our Board.

See “Named Executive Officer Compensation” for a detailed discussion of our compensation program and determinations for our named executive officers in 2025. The following table sets forth a summary of key compensation governance matters for our current program.

The compensation program for our named executive officers is designed to attract, motivate and retain qualified employees and to provide them incentives to achieve or exceed the Company’s annual operational, financial and strategic goals and to increase long-term stockholder value. The 2025 compensation program for named executive officers consisted of a base salary, an annual cash bonus opportunity, and annual equity awards (consisting of RSUs and PSUs). To further align our compensation program with stockholder interests, a substantial percentage of our 2025 annual equity awards consisted of PSUs.

Based on Company performance for 2025, our former Chief Executive Officer’s compensation was determined as follows:

Our Board has taken a reasonable, measured approach in implementing our corporate governance policies and practices.

Key elements of our current governance are set forth below.

On April 27, 2021, we entered into a stockholders’ agreement (the “Stockholders’ Agreement”) with Pamplona Capital Partners V, L.P., an investment fund (the “Pamplona Fund”) managed by affiliates of Pamplona Capital Management, LLC (together with its respective subsidiaries and affiliates, “Pamplona”), and Wynnchurch Capital Partners IV, L.P. (“Wynnchurch IV”) and WC Partners Executive IV, L.P. (“WC Executive”) (collectively, the “Wynnchurch Funds”), managed by affiliates of Wynnchurch Capital, L.P. (“Wynnchurch Capital,” and together with its respective subsidiaries and affiliates, “Wynnchurch”). The Stockholders’ Agreement grants Pamplona the right to nominate to our Board a number of designees on a sliding scale depending on Pamplona’s affiliates’ ownership of shares of the Company’s Common Stock, par value $0.0001 per share (our “Common Stock” or “shares of Common Stock”). Mr. Dellaquila, Mr. Laven, Mr. Pratt and Mr. Pruellage are the current designees of Pamplona under the Stockholders’ Agreement. Wynnchurch had certain director nomination rights, which they waived beginning in July 2022. For more information, see “Certain Relationships and Related Party Transactions—Stockholders’ Agreement.” References to our “Principal Stockholders” in this proxy statement refer to the Pamplona Fund, managed by Pamplona, and the Wynnchurch Funds, managed by Wynnchurch.

As a leading global manufacturer of in-ground swimming pools, our ambition is to lead the way towards a more sustainable future for our industry. We continue to work with independent consultants to assess and enhance our sustainability performance, benchmark our efforts against industry peers, establish a comprehensive strategy to manage sustainability risks and opportunities and publish an annual Sustainability Report. See “—Board of Directors and Corporate Governance—Oversight of Sustainability.”

Our Board is seeking stockholder support to ratify the appointment of Deloitte & Touche LLP (“Deloitte & Touche”) as our independent registered public accounting firm for 2026. Our Audit Committee has continued its engagement with Deloitte & Touche since 2020.

Our Board is asking our stockholders to approve an amendment (the “Amendment”) to the Latham Group, Inc. 2021 Omnibus Equity Incentive Plan, as amended (the “2021 Omnibus Equity Plan”). The 2021 Omnibus Equity Plan was initially adopted by our Board on April 12, 2021 and our stockholders on April 13, 2021, prior to the consummation of our IPO on April 27, 2021. It was subsequently amended on May 2, 2023 following approval by our stockholders at our 2023 annual meeting of stockholders, which amendment provided for an increase in the available shares as well as further enhancements to the compensation and governance best practices included therein.

We use awards under the 2021 Omnibus Equity Plan to attract and retain employees, ensure that our compensation program provides appropriate incentives to motivate our key employees, officers and non-employee directors to contribute to our long-term performance and growth, develop a culture of ownership, and align further the interests of participants and our stockholders. Stockholder approval of the Amendment will permit us to continue to grant equity compensation awards to our key employees, officers and non-employee directors in furtherance of this philosophy.

Our Board has determined that it is in the best interests of us and our stockholders to approve the Amendment, which includes an increase by 3,400,000 shares of the number of shares of Common Stock that may be issued pursuant to awards.

As of the record date, we had 2,868,643 shares of our Common Stock remaining available for issuance for awards under the 2021 Omnibus Equity Plan.

At our Annual Meeting, our stockholders will vote to elect the three Class II director nominees named in this proxy statement. Class II directors elected at our Annual Meeting will serve for three-year terms until our annual meeting of stockholders to be held in 2029 and until a successor has been duly elected and qualified, or until such director’s earlier resignation, retirement or other termination of service.

Based on its beneficial ownership of our Common Stock as of the record date, Pamplona has the right to designate four directors to our Board.

Our Board nominated Frank J. Dellaquila, Sean Gadd and William M. Pruellage for election to our Board as Class II directors at our Annual Meeting. These nominees were recommended by our Nominating and Corporate Governance Committee and approved for nomination by our Board, each in accordance with our established process for evaluating candidates to serve on our Board. Mr. Dellaquila and Mr. Pruellage are director designees of Pamplona.

Our Nominating and Corporate Governance Committee recommended the appointment of the three director nominees after considering each of their backgrounds, qualifications and professional experience. See “Board of Directors and Corporate Governance—Qualifications, Attributes, Skills and Experience of our Directors”, and “—Identifying and Evaluating Candidates for Director” for additional information thereon.

Each of Messrs. Dellaquila, Gadd and Pruellage currently serve on our Board, has consented to be named in this proxy statement and has agreed to serve, if elected. There are no family relationships among the director nominees or between them and any of our executive officers or continuing directors.

The following sets forth the biographical information regarding our Class II director nominees, including the experience, qualifications, attributes and skills that led our Board to conclude that each director should continue to serve on our Board.

If any nominee becomes unable or unwilling to serve between the date of this proxy statement and our Annual Meeting, which we do not anticipate, then our Board may designate a new nominee. In that case, the persons named as proxies on the attached proxy card will vote for that substitute nominee (unless the proxies were previously instructed to withhold votes for the nominee who has become unable or unwilling to serve). Alternatively, our Board may reduce its size.

Our Board currently consists of nine members and is divided into three classes. The members of each class serve staggered, three-year terms. At each annual meeting, our stockholders will be requested to elect the successors to one class of our directors for three-year terms. Each of our directors serves as a director until a successor has been duly elected and qualified, or until such director’s earlier resignation, retirement or other termination of service.

The authorized number of directors may be increased or decreased by our Board in accordance with our certificate of incorporation. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of our directors.

See “Certain Relationships and Related Party Transactions—Stockholders’ Agreement” for information regarding director nomination and other rights currently held by Pamplona.

See “Proposal One: Election of Class II Directors” for biographical information on our Class II directors. The following sets forth biographical information regarding our Class III and I directors, including the experience, qualifications, attributes and skills that led our Board to conclude that each director should continue to serve on our Board.

The following table sets forth a summary of additional key qualifications, attributes, skills and experience that our current directors contribute to our Board to ensure our Board fulfills its oversight role and responsibilities, in the context of the operations and strategy of our business and the long-term interests of stockholders.

Subject to the terms of the Stockholders’ Agreement, our Nominating and Corporate Governance Committee has, as one of its responsibilities, the recommendation of director candidates to our Board. Nominees for directorship are identified by our Nominating and Corporate Governance Committee in accordance with the criteria set forth below and any other criteria that may be identified by our Board or a committee of our Board, if appropriate, and in accordance with the procedures set forth in our Nominating and Corporate Governance Committee’s charter. Our Nominating and Corporate Governance Committee considers recommendations of director candidates from a range of sources, provided any recommendations are validly made in accordance with our governance documents and applicable law, and the Nominating and Corporate Governance Committee does not evaluate director candidates differently based on the source of the recommendation. From time to time, our Nominating and Corporate Governance Committee may also retain third-party search firms to identify, provide information on and evaluate suitable potential director candidates. Our Board seeks members from diverse professional and personal backgrounds who combine a broad spectrum of experience and expertise, as discussed above, with a reputation for integrity. Our Nominating and Corporate Governance Committee’s assessment of a potential candidate will include an individual’s independence, as well as consideration of skills and experience, in the context of the needs of the Company.

In addition to the key qualifications, attributes, skills and experience noted above, the minimum core criteria assessed by our Nominating and Corporate Governance Committee when evaluating a candidate for director include:

Our Common Stock is listed on the Nasdaq Global Select Market (“Nasdaq”). Our Board reviews director independence in accordance with the applicable rules of Nasdaq, based on the recommendation of our Nominating and Corporate Governance Committee. The independence rules include a series of objective tests, including that a director has not been employed by us within the last three years and has not engaged in various types of business dealings with us. In addition, our Board must make the subjective determination as to each independent director that no relationship exists which, in the opinion of our Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Our Board has determined that each of James E. Cline, Frank J. Dellaquila, DeLu Jackson, Jeffrey T. Jackson, Mark P. Laven, Suzan Morno-Wade, Brian Pratt and William M. Pruellage are independent directors under Nasdaq rules. Our Board further has determined that each member of our Audit Committee and our Compensation Committee qualifies as independent under the additional independence rules established by the U.S. Securities and Exchange Commission (the “SEC”) and Nasdaq for service on such Committees.

As outlined in our Corporate Governance Guidelines and further discussed below, our Board is elected by stockholders to provide oversight and strategic guidance to management. The basic responsibility of the directors is to exercise their business judgment to act in what they reasonably believe to be in the best interests of the Company and its stockholders. In discharging that obligation, directors are entitled to rely on the honesty and integrity of the Company’s officers, employees, outside advisors and independent auditors. Our Board selects and oversees management, to whom our Board delegates the authority and responsibility for the conduct of the day-to-day operations of the business. Our Board utilizes a strategic planning process to establish objectives and goals for the Company, taking into account the opportunities and risks of the Company’s business and affairs. Our Board reviews, approves and modifies as appropriate the strategies proposed by management to achieve such objectives and goals.

Our Board is led by our independent Chair, Mr. Cline, who has served in this capacity since December 2020 and is the former President and Chief Executive Officer of Trex. We believe this current leadership structure allows for Mr. Gadd, our President and Chief Executive Officer, to focus on executing the Company’s strategy and policies adopted by our Board and to lead and manage the

Company’s day-to-day operations and performance. Our Corporate Governance Guidelines provide that if the Company is not a controlled company and if our Chair of the Board is not an independent director, then our Board will appoint a Lead Director that is independent and such person will have many of the same responsibilities of our independent Chair.

The Company benefits from Mr. Cline’s significant leadership experience and accumulated expertise in the consumer products industry and specifically the outdoor living category. Mr. Cline’s roles, powers and responsibilities in serving as Chair of the Board include the matters set forth below.

Further, our independent Board leadership is enhanced by the deep engagement and critical insights provided by our eight independent directors. In addition, we have a fully independent Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee that provide significant oversight of key Board functions.

Our Board committees include our Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee. Each Committee operates under a written charter approved by our Board, which the applicable Committee and our Board review annually. Each charter is available under the Governance tab on our Investor Relations website, at https://ir.lathampool.com/. Our Committees are currently comprised entirely of independent directors.

See “Certain Relationships and Related Party Transactions—Stockholders’ Agreement” for information regarding Committee nomination and other rights currently held by Pamplona.

Our Nominating and Corporate Governance Committee recommends and our Board appoints our Committee members and Chairs. The following table provides membership as of the record date and meeting information for 2025 for each of these Committees. Mr. Gadd does not serve on any standing committees of our Board.

Our Audit Committee assists our Board by providing independent, objective oversight of our auditing, accounting and financial reporting activities. The principal duties and responsibilities of our Audit Committee are set forth below.

Our Audit Committee has the authority to retain counsel and other advisors to fulfill its responsibilities and duties. Our Audit Committee may also form and delegate authority to subcommittees, provided that the subcommittees are composed entirely of directors who satisfy the applicable independence requirements.

Our Board has determined that each of James E. Cline, Frank J. Dellaquila and Jeffrey T. Jackson qualifies as an “audit committee financial expert” and that each member of our Audit Committee has sufficient knowledge in reading and understanding financial statements.

Our Audit Committee charter also provides that an Audit Committee member may not simultaneously serve on more than two other audit committees of public companies unless our Board determines that such service would not impair the ability of such person to effectively serve on our Audit Committee. No Audit Committee member currently serves on more than two other audit committees of public companies.

See “Report of our Audit Committee,” “Other Audit Committee Matters,” and “Proposal Two: Ratification of the Appointment of Deloitte & Touche as our Independent Registered Public Accounting Firm for 2026” for additional information regarding Audit Committee activities.

Our Compensation Committee is responsible for overseeing the compensation of our Chief Executive Officer and other executive officers, and for oversight of our incentive compensation and equity-based plans. The principal duties and responsibilities of our Compensation Committee are set forth below.

Our Compensation Committee may form and delegate authority to subcommittees, provided that the subcommittees are composed entirely of directors who satisfy the applicable independence requirements.

Our Board has determined that each member of our Compensation Committee qualifies as a non-employee director under applicable rules and regulations of the SEC.

Our Compensation Committee has the authority to retain counsel and other advisors to fulfill its responsibilities and duties. In connection with the engagement of such advisors generally, our Compensation Committee reviews the independence of such advisor, based on factors specified by Nasdaq, and other factors it deems appropriate, and specifically with respect to any compensation consultant, any actual or potential conflicts of interest.

Our Compensation Committee determined to re-engage Pearl Meyer & Partners, LLC, its independent compensation consultant since 2020. Upon engagement, and consistent with historical practice, our Compensation Committee worked with management to determine Pearl Meyer’s responsibilities and direct its work product for 2025, although our Compensation Committee was responsible for formal approval of the work plan. Pearl Meyer performed no other services for us for 2025, and our Compensation Committee determined there were no conflicts of interest raised by the work of Pearl Meyer for 2025.

Our Compensation Committee also regularly receives input from management, including our Chief Executive Officer, our General Counsel and our Chief Human Resources Officer, with respect to the Company’s executive compensation program and other human capital matters.

See “Named Executive Officer Compensation” and “Named Executive Officer Compensation Tables” for further information on the activities of our Compensation Committee, Pearl Meyer and management regarding the consideration and determination of named executive officer compensation in 2025, and “Director Compensation” for further information on the activities of our Compensation Committee and Pearl Meyer regarding our 2025 non-employee director compensation program.

Our Nominating and Corporate Governance Committee identifies and recommends director nominees to our Board for election, develops and recommends to our Board the Corporate Governance Guidelines and other key governance policies, and oversees Board and Committee self-evaluations. The principal duties and responsibilities of our Nominating and Corporate Governance Committee are set forth below.

Our Nominating and Corporate Governance Committee has the authority to retain counsel and other advisors to fulfill its responsibilities and duties. Our Nominating and Corporate Governance Committee may also form and delegate authority to subcommittees, provided that the subcommittees are composed entirely of directors who satisfy the applicable independence requirements.

See “—Qualifications, Attributes, Skills and Experience of our Directors” and “—Identifying and Evaluating Candidates for Director” for a description of the experience, mix of skills and other criteria that our Nominating and Corporate Governance Committee considers in the director nomination process or to fill vacancies or newly created directorships.

See “Questions and Answers—When are stockholder proposals due for next year’s annual meeting of the stockholders?” for information for stockholders to present timely notice of stockholder proposals and director nominations. See also our Amended and Restated Bylaws for additional information required to nominate candidates for election as directors or to bring other business before an annual stockholder meeting.

Our Board and Committees meet throughout the year generally on a set schedule, and also hold special meetings and act by written consent as appropriate. Our Board held six meetings during 2025. Our non-management directors hold regularly scheduled executive sessions, which generally occur around regularly scheduled meetings of our Board. The independent directors also meet in executive session at least annually.

All directors are expected to attend all of the meetings of our Board and our Board committees on which they serve. During 2025, each person currently serving as a director attended at least 75% of the aggregate of the total number of meetings of our Board and each Committee of which such director was a member. Each director also is encouraged and expected to attend the Company’s annual meeting. All of our current directors who were then serving on our Board attended the 2025 annual meeting.

Our Board and Committees have a significant role in overseeing management’s activities regarding risk identification, risk management and risk mitigation. While each Committee is responsible for specific matters, our Board is informed regularly through Committee reports about material activities and discussions. Our Board and Committees also regularly meet to discuss these matters in executive session with their independent advisors and other advisors, as well as with certain members of management. Set forth below is a non-exhaustive list of key risk topics that are subject to Board and Committee oversight.

Our Board and management are committed to responsible corporate governance to ensure that we are managed in the best interests of our stockholders. Our Board periodically reviews and updates our key governance policies. Each policy below is available under the Governance tab on our Investor Relations website, at https://ir.lathampool.com/.

Our Board has adopted Corporate Governance Guidelines, which provide the framework for our corporate governance along with our Amended and Restated Certificate of Incorporation, Amended and Restated Bylaws, committee charters and other key governance practices and policies. Our Corporate Governance Guidelines cover a wide range of subjects, including the conduct of Board meetings, independence and selection of directors, director retirement, Board membership criteria, Board committee composition, and the reimbursement of fees and related travel and accommodation expenses for outside education programs pertaining to the directors’ responsibilities, as appropriate.

Our Board has adopted a Code of Conduct and Business Ethics, which is applicable to all directors, officers and employees, including our Chief Executive Officer and Chief Financial Officer. This policy addresses, among other things, ethical principles, insider trading, conflicts of interest, compliance with laws, safety and health, company records and confidentiality. To the extent required by SEC rules, we intend to disclose any amendments to our Code of Conduct and Business Ethics, and any waiver of a provision of the Code of Conduct and Business Ethics with respect to our principal executive officer,

principal financial officer, principal accounting officer or controller, or persons performing similar functions, on our website referred to above within four business days following any such amendment or waiver, or within any other period that may be required under SEC rules from time to time.

Our Board has adopted a Securities Trading Policy governing the purchase, sale, and/or other dispositions of our securities by directors, officers, employees and other specified persons. Our Securities Trading Policy is designed to promote compliance with insider trading laws by informing, educating and creating reasonable processes to prevent the Company and its directors, officers, employees and other specified persons from insider trading violations and the appearance of any related improper conduct. The policy prohibits the trading of our securities on the basis of material nonpublic information, establishes regular blackout periods when directors, executive officers and other specified persons are prohibited from trading in our securities, and requires legal compliance for any insider trading plans intended to rely on the affirmative defense against insider trading liability in accordance with Rule 10b5-1 under the Exchange Act. Additionally, the policy specifically prohibits all directors, officers and other employees from speculating in our stock, including trading in options, warrants, puts and calls, or similar derivative securities, and selling our stock short. A copy of our Securities Trading Policy is filed as an exhibit to our Annual Report on Form 10-K for 2025.

Our Corporate Governance Guidelines prohibit directors, executive officers and employees of the Company, and their designees from purchasing any financial instruments (including prepaid variable forward contracts, equity swaps, collars and exchange funds) or otherwise engaging in transactions that are designed to or have the effect of hedging or offsetting any decrease in the market value of the Company’s equity securities whether such securities are (1) granted to the director, officer or employee by the Company as part of such director’s, officer’s or employee’s compensation; or (2) held, directly or indirectly, by the director, officer or employee.

Directors, executive officers and employees and their designees are prohibited from engaging in hedging transactions, such as purchasing securities of the Company on margin or pledge, or otherwise grant a security interest in, securities of the Company in margin accounts.

Our Nominating and Corporate Governance Committee leads our annual self-evaluation program for our Board and Committees, including recommending the scope and the process. In 2025, members of our Board and each Committee completed a written questionnaire to evaluate and enhance such governing body’s culture, structure, process and effectiveness. At the request of our Nominating and Corporate Governance Committee, the General Counsel received all comments, analyzed the results and provided a summary to our Board. The Chair of the Board then led a Board discussion regarding such results and opportunities to improve the effectiveness of our Board and Committees. Action plans are developed to address key areas of improvement or enhancement areas, and progress is evaluated throughout the year.

To achieve long-term success as a business, we realize we need to align our business strategy and prioritization with the expectations of our stakeholders and society at large. As a leading global manufacturer of in-ground swimming pools, our ambition is to lead our industry towards a more sustainable future.

In 2021, we completed Latham’s first materiality assessment, which identified the priority sustainability topics and actions that are most relevant to our business and our stakeholders. The result was a materiality matrix that identified the priority areas for our sustainability program:

We published our 2024 sustainability report in the fourth quarter of 2025, which highlighted our progress in each of the priority areas listed above, including:

We intend to publish an annual sustainability report to update our stakeholders on our ongoing journey. See https://ir.lathampool.com/esg for more information.

Our Board views oversight and effective management of sustainability related risks and opportunities as essential to the Company’s ability to execute its strategy and achieve long-term sustainable growth. Our management team develops our sustainability strategy and related goals and policies through a sustainability working group, and our sustainability program is overseen by our Nominating and Corporate Governance Committee. Our Nominating and Corporate Governance Committee and sustainability working group are involved in policy planning and the coordination of corporate-wide sustainability efforts. The working group is a cross-functional team managing the day-to-day implementation of company initiatives and accountability for performance. Our Nominating and Corporate Governance Committee reviews the Company’s progress towards the achievement of its sustainability strategy and goals on a periodic basis.

As of December 31, 2025, we had approximately 1,804 full-time employees. We believe we have satisfactory relations with our employees.

Our reputation for exceptional products, services and quality relies on the performance of our exceptional people, so we ensure that our team is rewarded, engaged and developed to build fulfilling careers. We provide competitive employee wages that are appropriate to employee positions, skill levels, experience, knowledge and geographic location, and additional rewards including incentive plans, bonus plans and achievement awards. In the United States, we offer our employees a market competitive array of health, welfare and retirement benefits, and for employees located outside the United States, we offer benefits that may vary from those offered to our U.S. employees due to customary local practices and statutory requirements. We benchmark our benefits plan annually to ensure our employee value proposition remains competitive and attractive to new talent. In all locations, we provide time off benefits, company-paid holidays, retirement benefits, wellness benefits, recognition programs and career development opportunities.

Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating our existing and new employees. Our talented employees drive our purpose and mission and share core values that both stem from and define our culture, which plays an invaluable role in our execution at all levels in our organization. Our culture is based on shared core values which we believe contribute to our success and the continued growth of the organization. Our values recently have been updated to better define Latham’s culture of safety, passion, leadership, accountability, simplicity and heart (fun, wellness, diversity, community and environment). A third-party vendor conducts annual engagement surveys on our behalf. We have used the same survey process for eight consecutive years, and we are proud to see our engagement score increased in 2025 and remains at a high level based on our sustained employee engagement focus.

The health and safety of our people is a primary concern for us, so we have implemented a comprehensive health and safety program to manage workplace safety hazards and to protect employees. We provide regular training and competency development to verify and ensure compliance with health and safety procedures and regulations.

Employee engagement is a fundamental aspect of our culture. We are committed to creating a culture where employees feel supported, connected, and empowered to do their best work. Annually, we conduct an employee engagement survey to provide insight into the employee experience and to guide Latham in its continuous improvement efforts around culture. Our annual engagement survey results increased 8% from 2024 to 2025.

Latham’s policies and practices are designed to encourage and reinforce a respectful and exceptional workplace culture through the entire employee life cycle, including recruitment, compensation, benefits offerings and designs, employee development and training, promotions, internal mobility, and internal communications.

We believe that learning and development is a strategic driver for the mutual success of our workforce and our dealers, and we encourage employees to steer their career development through learning. Learning programs for employees through the Latham Learning program include new hire onboarding and curriculum in key areas such as safety, products, sales, customer service and annual compliance training, including our Code of Conduct and Business Ethics, information and systems security and our Securities Trading Policy. Additional offerings include skills-based training, career pathing, professional certification training and tuition reimbursement for post-secondary education. External programs are offered to customers through Latham University and teach business management and planning, product safety and installation techniques. We believe these educational programs enhance Latham’s value to our dealers as a key partner in their success.

We have taken important action to reinforce that safety is one of our highest priorities, including setting the tone-at-the-top through safety-focused communications from our Chief Executive Officer, and other leaders throughout the organization. Our health and safety policies and practices include an employee training and competency development program to train, verify and encourage compliance with health and safety procedures and regulations annually. We monitor our total recordable incident rate monthly as part of our Operations Review. We review workplace injury and claims trends with our carriers monthly to identify areas of focus and opportunities for implementing new programs to protect our employees. Our Environmental, Health and Safety team, led by our Director of Environment Health Safety, is responsible for managing, auditing and executing unified, company-wide safety and compliance programs; working directly with site leadership and associates on safety awareness, reports and preventative measures; and reporting regularly to Executive Leadership. Employee

wellness is facilitated through the Human Resources organization and includes external vendor partnerships, wellness incentives, biometric screenings, onsite programs and supplemental resources through our Employee Assistance Program and employee health benefits providers which are highly accessible to our employees and their family members for holistic wellness services.

Our Compensation Committee reviews a succession plan for the Company’s officers annually and reports on the plan and recommends any changes to our Board. Our Chief Executive Officer and Chief Human Resources Officer conduct a succession planning process as part of our talent development strategy, whereby we provide high potential employees with opportunities to prepare for advancement, such as through formal mentorships with senior leaders and/or members of the Board, external training, and interim or permanent assignments to roles with additional responsibilities. This ongoing program assures contingency and long-term key talent planning for executives, senior leadership and functional leaders throughout the Company.

Our Board and management value the opportunity to engage with our current and prospective stockholders to better understand their priorities, and to foster consistent and constructive dialogue. Throughout the year, our executive leadership and investor relations consultants engage with our stockholders at investor conferences and in private meetings to seek their input, to remain well-informed regarding their perspectives and help increase their understanding of our business and industry. Management also provides our Board with additional information regarding institutional voting and governance policies and trends in stakeholder issues. Our Board utilizes the information and feedback to inform key decisions and long-term strategy.

Stockholders and other interested parties desiring to communicate directly with the full Board, the non-management directors as a group or with any individual director or directors may do so by sending such communication in writing, addressed to the attention of the intended recipient(s), c/o Corporate Secretary, Latham Group, Inc., 787 Watervliet Shaker Road, Latham, NY 12110.

All communications that relate to accounting, internal accounting controls or auditing matters can be sent through https://lppi.compliancelinemcr.com/ and will be referred to the Chair of our Audit Committee unless the communication is otherwise addressed. All other communications received will be forwarded to the appropriate director or directors.

Our non-employee director compensation program is intended to attract and retain non-employee directors and align the interests of our Board and stockholders. All employee directors and directors affiliated with our Principal Stockholders do not participate in such compensation program.

Each year, after reviewing peer group benchmarking data, market data and discussions with our independent compensation consultant, our Compensation Committee develops, and recommends for approval by the Board, proposed compensation for our non-employee directors. Our Compensation Committee reviewed benchmarking and market data in December 2024, and determined to continue the existing non-employee director compensation program in 2025 without change.

The following table sets forth the compensation program for non-employee directors in 2025.

The annual cash retainers for Board and Committee service are paid in quarterly installments and in arrears, subject to the director’s continued service as of such payment date. Directors who resign or retire from our Board while in good standing prior to the end of the relevant quarter are eligible to receive a pro rata payment for their service through their last date of service of the relevant quarter.

The annual equity retainers will be granted either in shares of restricted stock or RSUs, as determined annually by our Compensation Committee. In 2025, our Compensation Committee determined to grant RSUs. The grant value is divided by the grant date fair market value, which is equal to the closing price of our Common Stock on the grant date, to calculate the number of shares issued. The equity awards will vest on the first anniversary of the grant date, unless the director is removed for cause or voluntarily resigns prior to vesting.

The Company generally does not provide any perquisites to directors.

The 2021 Omnibus Equity Plan provides that the sum of any cash compensation for service as a director and the grant date fair value of all equity awards for service as a director will not exceed $750,000 in any calendar year.

In 2023, our Compensation Committee approved Stock Ownership Guidelines for executive officers and non-employee directors. Non-management directors are required to own qualifying Common Stock having a value of at least three times the annual cash retainer for Board service (excluding other

additional cash retainers). All persons covered by the guidelines are required to retain 50% of the qualifying Common Stock that vest pursuant to equity awards granted by the Company until the ownership level is met. All non-management directors of our Board are in compliance with our Stock Ownership Guidelines or are within the phase-in period for attaining their applicable minimum stock ownership threshold requirement. See “Named Executive Officer Compensation—Compensation Policies—Stock Ownership Guidelines” for additional information.

The following table sets forth information regarding the compensation paid to, awarded to or earned by the members of our Board for services rendered in 2025. Mr. Rajeski, our former President, Chief Executive Officer and Class II director, is a named executive officer and did not receive any compensation for his director service in 2025, and his compensation is disclosed in the Summary Compensation Table for 2025 and 2024.

At December 31, 2025, the following directors held the following amount of RSUs: Mr. Cline, 22,124; Messrs. Dellaquila, D. Jackson and Laven, and Ms. Morno-Wade, 16,814.

Our Audit Committee’s purpose is to assist our Board in generally overseeing, among other things, the integrity of our financial reporting and internal control functions, to review our reports filed with or furnished to the SEC that include financial statements or results, to monitor compliance with significant legal and regulatory requirements and other risks related to financial reporting and internal control, and to appoint, retain, compensate, and oversee the scope of work and planned procedures of our independent registered public accounting firm, which is currently Deloitte & Touche. See “Other Audit Committee Matters” below for a description of our Audit Committee’s pre-approval policies regarding the services of Deloitte & Touche.

Our Audit Committee relies on the expertise and knowledge of management, members of our internal audit/risk function, and the independent registered public accounting firm in carrying out its oversight responsibilities. Management is responsible for the preparation, presentation and integrity of our financial statements, accounting and financial reporting principles, internal controls and compliance with applicable laws and regulations. Deloitte & Touche, as our independent registered public accounting firm, is responsible for performing an independent audit of our consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (U.S.) (“PCAOB”) and for expressing its opinion thereon.

In fulfilling its oversight responsibilities regarding our financial statements for 2025, our Audit Committee:

Based on our Audit Committee’s review and discussions noted above, our Audit Committee recommended to our Board, and our Board approved, that our audited consolidated financial statements be included in our Annual Report on Form 10-K for 2025, which was filed with the SEC on March 4, 2026. Our Audit Committee also appointed Deloitte & Touche as our independent registered public accounting firm for 2026.

Our Audit Committee has the sole authority to review and pre-approve all audit and non-audit services to be provided by our independent registered public accounting firm, or any other auditors as permitted by applicable law, as well as all related fees and other terms of engagement, to ensure the provision of these services do not impair such auditor’s independence. Our Audit Committee has considered the nature and amount of the fees billed by Deloitte & Touche and believes that the provision of the services for activities unrelated to the audit is compatible with maintaining Deloitte & Touche’s independence.

If a product or service arises that has not been pre-approved by our Audit Committee, our Audit Committee has delegated to the Chair of our Audit Committee the authority to consider and pre-approve any such product or service between regular meetings of our Audit Committee. Any interim approvals granted by the Chair of our Audit Committee are reported to our Audit Committee at its next regularly scheduled meeting.

The following table presents fees for professional audit services rendered by Deloitte & Touche for the audit of our consolidated financial statements, and fees billed for other services rendered by Deloitte & Touche, for 2025 and 2024.

Our Audit Committee has ultimate authority and responsibility to appoint, compensate, evaluate and, when appropriate, replace our independent registered public accounting firm.

Our Audit Committee conducted a competitive process to select an independent registered public accounting firm for 2020, and Deloitte & Touche was selected and appointed at such time. Our Audit Committee has continued its engagement with Deloitte & Touche since such appointment.

For the reasons noted below, our Audit Committee has reappointed Deloitte & Touche as our independent registered public accounting firm for 2026.

In determining that retaining Deloitte & Touche for 2026 was in the best interests of us and our stockholders, our Audit Committee reviewed:

Our Audit Committee appoints our independent registered public accounting firm, and your ratification of the appointment of Deloitte & Touche is not necessary. However, our Audit Committee will take your vote on this proposal into consideration when appointing our independent registered public accounting firm in the future. Even if the stockholders ratify the appointment of Deloitte & Touche, our Audit Committee may in its sole discretion terminate the engagement of Deloitte & Touche and direct the appointment of another independent auditor at any time during the year, although it has no current intent to do so.

Representatives of Deloitte & Touche will attend our Annual Meeting, will have the opportunity to make a statement, if they desire to do so, and will be available to answer appropriate questions from stockholders.

The following table sets forth information with respect to our executive officers as of March 20, 2026.
