This proxy statement supplement, dated March 31, 2023 (this "Supplement"), supplements the definitive proxy statement on Schedule 14A (the "Proxy Statement") of Latham Group, Inc. (the "Company"), filed with the Securities and Exchange Commission (the "SEC") on March 21, 2023 and relating to the 2023 Annual Meeting of Stockholders of the Company (the "Annual Meeting") to be held on Tuesday, May 2, 2023 at 8:00 a.m. Eastern Daylight Time, at Saratoga National Golf Club, 458 Union Avenue, Saratoga Springs, NY 12866.

Director Resignation

On March 29, 2023, Dane L. Derbyshire resigned as a Class III member of the Board of Directors of the Company (the "Board") and as a member of the Nominating and Corporate Governance Committee of the Board (the "Nominating and Corporate Governance Committee"), each effective immediately, in connection with his departure from Pamplona Capital Management. His decision to resign was not the result of any disagreement with management or the Board related to the Company's operations, policies, or practices. Mr. Derbyshire had been a director designee of Pamplona Capital Partners V, L.P. ("Pamplona") in accordance with the Stockholders Agreement among the Company, Pamplona, Wynnchurch Capital Partners IV, L.P. and WC Partners Executive IV, L.P., dated as of April 27, 2021 (the "Stockholders Agreement").

Director Appointments

Following the director appointments noted below, six of nine directors are independent, and the Audit and Compensation Committees continue to be comprised solely of independent directors.

#### Brian Pratt
On March 30, 2023, the Board appointed Brian Pratt, age 28, to the Board as a Class III member of the Board and to serve as a member of the Nominating and Corporate Governance Committee to fill the vacancy upon the resignation of Mr. Derbyshire, effective immediately. Mr. Pratt was appointed to the Board as a director designee of Pamplona under the Stockholders Agreement. Accordingly, Mr. Pratt will not receive compensation as a non-employee director of the Company. However, Mr. Pratt will enter into the Company's standard form of indemnity agreement for directors (the "Indemnity Agreement"). Except for applicable matters regarding Pamplona and its affiliates specified in the Proxy Statement, Mr. Pratt does not have a material interest in any transaction that is required to be disclosed under Item 404(a) of Regulation S-K. The Board has determined that Mr. Pratt is an independent director of the Board.

Mr. Pratt is a Vice President at Pamplona Capital Management LLC, having joined the firm in March 2019. Since 2019, Mr. Pratt has worked closely with the Board and Latham management on financial, operational and transactional matters. Mr. Pratt serves as a board observer of several other companies, including BFG Supply, a national distributor of consumables, greenhouse durables, and technical equipment to the green industry, and CSC ServiceWorks, Inc., a provider of commercial laundry services and air vending solutions. Prior to joining Pamplona, Mr. Pratt worked in the investment banking division

#### DeLu Jackson
On March 30, 2023, the Board appointed DeLu Jackson, age 50, to the Board as a Class I member of the Board to fill an existing vacancy on the Board following the departure of a Class I member in July 2022. The Board also appointed Mr. Jackson to serve as a member of the Audit Committee of the Board, replacing Suzan Morno-Wade, and the Nominating and Corporate Governance Committee, replacing Alex Hawkinson. The foregoing appointments were effective immediately. Mr. Jackson will receive compensation under our non-employee director Compensation program. He will also enter into the Indemnity Agreement with the Company. Mr. Jackson does not have a material interest in any transaction that is required to be disclosed under Item 404(a) of Regulation S-K. The Board has determined that Mr. Jackson is an independent director of the Board and that he satisfies all applicable requirements to serve on the Audit Committee, including without limitation the applicable requirements of Nasdaq and the Securities Exchange Act of 1934, as amended.

Since September 2021, Mr. Jackson has served as Executive Vice President and Chief Marketing Officer of ADT Inc., a leader in smart home and small business security. From August 2017 until September 2021, Mr. Jackson was Vice President—Head of Marketing and Digital at Conagra Brands, Inc., a leading branded food company. Before joining Conagra Brands, he served in senior digital and marketing roles for domestic and international brands, including Kellogg Company, McDonald's Corporation, Nissan Motor Co., Ltd, Audi of America and Subaru of America. Mr. Jackson also serves on the board of directors of Brag House Inc. (an esports platform), the Western Golf Association and the Chicago Public Library Foundation. Mr. Jackson holds an MBA from NYU Stern School of Business and a BA in Politics from Princeton University. We believe Mr. Jackson is qualified to serve as a member of our Board because of his experience as a public company executive, his expertise in digital and marketing strategy and knowledge of consumer products.
