Legal Proceedings The Company is involved from time to time in various legal proceedings arising in the ordinary course of its business, including primarily commercial, product liability, employment and intellectual property claims. In accordance with U.S. GAAP, the Company records a liability in its consolidated financial statements with respect to any of these matters when it is both probable that a liability has been incurred and the amount of the liability can be reasonably estimated. If a material loss is reasonably possible but not known or probable, and may be reasonably estimated, the estimated loss or range of loss is disclosed. With respect to currently pending legal proceedings, the Company has not established an estimated range of reasonably possible material losses either because it believes that it has valid defenses to claims asserted against it, the proceeding has not advanced to a stage of discovery that would enable it to establish an estimate, or the potential loss is not material. The Company currently does not expect the outcome of pending legal proceedings to have a material effect on its consolidated results of operations, financial position or cash flows. Litigation, however, is inherently unpredictable, and it is possible that the ultimate outcome of one or more claims asserted against the Company could adversely impact its consolidated results of operations, financial position or cash flows. The Company expenses legal costs as incurred. Purported Class Action Complaint On January 14, 2025, purported customers served a putative class action complaint on behalf of themselves and a putative class of California consumers against Sleep Number in the United States District Court for the Central District of California alleging that Sleep Number’s beds are perpetually on sale in violation of California law. The Plaintiff sought injunctive relief, damages and attorney’s fees. Sleep Number brought a motion to dismiss for failure to state a claim and a motion to transfer or, alternatively, dismiss based on the first-to-file doctrine (citing the purported class action complaint filed on September 27, 2024 as described below). On April 8, 2025, the Court granted Sleep Number’s motion to transfer or, alternatively, dismiss and dismissed the matter in its entirety based on the first-to-file doctrine. The plaintiffs did not appeal the dismissal. Purported Class Action Complaint On September 27, 2024, a purported customer served a putative class action complaint on behalf of themself and a putative class of California consumers against Sleep Number in the United States District Court for the Eastern District of California alleging that Sleep Number’s beds are perpetually on sale in violation of California law. The plaintiff seeks injunctive relief, damages and attorney’s fees.
