Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	12. Commitments and Contingencies Litigation The Company is involved in litigation arising in the normal course of business, including involving product liability claims. Where appropriate, these matters have been submitted to the Company’s insurance carrier. The Company determines whether an estimated loss from a contingency should be accrued by assessing whether a loss is deemed probable and can be reasonably estimated. It is not possible to quantify the ultimate liability, if any, in these matters. On August 2, 2023, a securities class action complaint was filed in the United States District Court for the District of New Jersey against the Company and certain of its current directors and officers (Kevin Holleran and Eifion Jones) and MSD Partners, L.P. and CCMP Capital Advisors, LP on behalf of a putative class of stockholders who acquired shares of the Company’s Common Stock between March 2, 2022 and July 27, 2022. That action is captioned City of Southfield Fire and Police Retirement System vs. Hayward Holdings, Inc., et al., 2:23-cv-04146-WJM-ESK (D.N.J.) (“City of Southfield”). On September 28, 2023, a second, related securities class action complaint was filed in the United States District Court for the District of New Jersey against the Company and certain of its current directors and officers (Kevin Holleran and Eifion Jones) and MSD Partners, L.P. and CCMP Capital Advisors, LP on behalf of a putative class of stockholders who acquired shares of the Company’s Common Stock between October 27, 2021 and July 28, 2022. That action is captioned Erie County Employees’ Retirement System vs. Hayward Holdings, Inc., et al., 2:23-cv-04146-WJM-ESK (D.N.J.) (“Erie County”). On December 19, 2023, the Court issued a ruling consolidating the two securities class actions (City of Southfield and Erie County) under the City of Southfield docket (the “Securities Class Action”) and appointing a lead plaintiff. In a consolidated class action complaint filed on March 4, 2024, the lead plaintiff alleged on behalf of a putative class of stockholders who acquired shares of the Company's Common Stock between October 27, 2021 and July 28, 2022, among other things, that the Company, Kevin Holleran, and Eifion Jones violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") by, among other things, making materially false or misleading statements regarding inventory, growth, and demand trends and the Company’s financial projections for 2022. On October 2, 2024, the Court issued an Opinion and Order dismissing the consolidated class action complaint and granting the lead plaintiff leave to file an amended complaint within 30 days. On November 1, 2024, the lead plaintiff filed a consolidated amended class action complaint making substantially similar allegations as in the consolidated class action complaint, but adding additional defendants affiliated with MSD Partners, L.P. and CCMP Capital Advisors, LP. On December 18, 2024, the Company and all other defendants moved to dismiss the consolidated amended class action complaint. On June 4, 2025, the Court issued an Opinion and Order granting in part and denying in part the motion to dismiss. The Court thereafter ordered the parties to mediation. On November 20, 2025, the parties reported to the Court that they had reached a settlement in principle, which is subject to Court approval. On February 28, 2026, the Court granted preliminary approval of settlement. On July 28, 2026, the Court ordered final approval of the settlement. The Securities Class Action seeks unspecified monetary damages on behalf of a putative class and an award of costs and expenses, including reasonable attorneys’ fees. On November 27, 2023, a shareholder derivative lawsuit was filed in the United States District Court for the District of New Jersey against current and past officers and directors of the Company captioned Heicklen v. Holleran, et al., 2:23-cv-22649 (D.N.J.) (the “Heicklen Action”). On August 28, 2025, a second shareholder derivative lawsuit was filed in the United States District Court for the District of New Jersey against current and past officers and directors of the Company, as well as defendants affiliated with MSD Partners, L.P., CCMP Capital Advisors, LP, and Alberta Investment Management Corporation captioned Hertzog v. Holleran, et al., 2:25-cv-14856 (D.N.J.) (the “Hertzog Action”). On November 18, 2025, a third shareholder derivative lawsuit was filed in the Court of Chancery of the State of Delaware against certain current and past officers and directors of the Company, as well as defendants affiliated with MSD Partners, L.P. and CCMP Capital Advisors, LP captioned Roberta Tackett, Aqua Palace, LLC and Jennifer Roberts vs. Hayward Holdings, Inc., et. al., C.A. No. 2025-1344 (Del. Ch.) (the “Tackett Action”). On April 9, 2026, a fourth shareholder derivative lawsuit was filed in the Court of Chancery of the State of Delaware against certain current and past officers and directors of the Company captioned David Aitken vs. Kevin Holleran, et al., C.A. 2026-0472 (Del. Ch.) (the "Aitken Action" and together with the Heicklen, Hertzog, and Tackett Actions, the "Derivative Actions"). The Derivative Actions allege claims for breaches of fiduciary duties to Company stockholders and/or aiding and abetting breaches of fiduciary duties in connection with the claims in the Securities Class Action. The Heicklen Action also alleges claims for unjust enrichment, corporate waste, and violations of Section 10(b) of the Exchange Act. The Hertzog Action also alleges claims for insider trading, corporate waste, and violations of Sections 14(a), 21D, 20(a), 29(B) of the Exchange Act. The Tackett Action also alleges claims for insider trading and aiding and abetting insider trading. The Aitken Action also alleges claims for unjust enrichment and waste of corporate assets. The plaintiffs in the Derivative Actions seek recovery of unspecified compensatory and punitive damages and attorneys' fees and costs, improvements to the Company’s corporate governance and internal procedures, disgorgement, and restitution. The Heicklen and Hertzog Actions are presently stayed. In the Tackett and Aitken Actions, defendants’ time to respond to the complaint has not yet commenced. We dispute the allegations of wrongdoing in the Securities Class Action and the Derivative Actions. During the three months ended June 27, 2026, the remaining $9.9 million of the Securities Class Action settlement was paid. In view of the complexity and ongoing and uncertain nature of the outstanding proceedings and inquiries, at this time we are unable to estimate a reasonably possible range of the financial obligation that we may incur to resolve the Derivative Actions. Additional expenses incurred, if any, related to these cases are subject to insurance recoveries pursuant to the Company’s retention amount with its insurance carriers. Contingencies On February 20, 2026, the United States Supreme Court issued a ruling striking down certain tariffs previously imposed under the International Emergency Economic Powers Act (“IEEPA”). Following the Supreme Court’s decision, the U.S. announced its intention to invoke other laws to collect tariffs and announced new tariffs on imports, in addition to any existing non-IEEPA tariffs. There remains substantial uncertainty regarding the duration of existing and newly announced tariffs, potential changes or pauses to such tariffs, tariff levels, and whether further additional tariffs or other retaliatory actions may be imposed, modified, or suspended, and the impacts of such actions on our business. Furthermore, the Company has received, and may be eligible to receive additional refunds of certain tariffs it paid that were levied under the IEEPA. The availability, amount and timing of any additional refunds is uncertain and subject to further developments. In the event the Company receives additional refunds of tariffs previously paid, it may elect or be required to return a portion of such amounts to customers that provided the Company tariff relief and/or price concessions. Any such obligations could reduce any benefit from a refund. No material refund asset or liability has been recorded as of the three months ended June 27, 2026. The Company participates in customs duty drawback programs that provide for the refund of certain import duties, taxes, and fees paid on imported material that is subsequently exported. Such recoveries are subject to review, audit, and final liquidation by customs authorities and require compliance with statutory filing deadlines and documentation requirements. Although we do not currently estimate any additional duty drawback claims related to the current year or prior years to be refunded to CBP, we continue to assess our obligations. Future recoveries of these claims, if any, may differ from amounts previously estimated.
