Commitments and Contingencies	Commitments and Contingencies On February 11, 2026, a putative class action complaint was filed against UL LLC, UL Solutions Inc., UL Standards and Engagement and UL Research Institutes (collectively, the “Defendants”) in the United States District Court for the Northern District of Illinois captioned John Martucci, on behalf of himself and the Putative Class v. Underwriters Laboratories Inc., et al., Case No. 1:26-cv-01561. The complaint alleges, among other things, that certain combination-listed single databus burglar and fire alarm system control units (the “Alarm Systems”) tested by the Defendants have defects that the Defendants concealed from and/or failed to disclose to consumers and that the Defendants listed the Alarm Systems as compliant with UL and National Fire Protection Association 72 standards when they were not compliant with such standards. The complaint seeks an order certifying a nationwide class and a New Jersey subclass; compensatory, actual, treble, statutory, punitive, and/or other damages; equitable relief, including restitution and disgorgement of profits; injunctive relief; declaratory relief; and pre and post judgment interest, attorneys’ fees and costs. The Company currently believes the claims are without merit and intends to vigorously defend against this action. A reasonable estimate of the amount of any possible loss or range of loss cannot be made at this time. The Company is, in the ordinary course of business, party to certain claims, litigation, audits and investigations. The Company will record an accrual for a loss contingency when it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. The Company believes it has established adequate accruals for liabilities that are probable and reasonably estimable and that may be incurred in connection with any such currently pending or threatened matter, none of which are material. In the Company’s opinion, the settlement of any such currently pending or threatened matter is not expected to have a material impact on the Company’s financial position, results of operations, or cash flows.
