ITEM 1. LEGAL PROCEEDINGS

From time to time, we are involved in various proceedings, lawsuits, disputes and claims arising in the ordinary course of the Company’s business, whether that be matters involving commercial operations, product liability, intellectual property or employment actions, including class action lawsuits. We accrue for loss contingencies when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated based on circumstances and assumptions existing at the time. Unless otherwise disclosed below, while the outcome of such claims cannot be predicted with certainty, we believe their ultimate resolution is not expected to have a material adverse effect on our business, financial condition, results of operations or liquidity. However, if an unfavorable ruling were to occur in any specific case, a material impact on the results of operations could be possible for that period.

Securities Class Action

On May 5, 2025, New England Teamsters Pension Fund filed a class action against us and certain of our current and former officers in the United States District Court for the Eastern District of Pennsylvania, purportedly on behalf of a class of the Company’s investors who purchased or otherwise acquired the Company’s common stock between February 16, 2023 and February 12, 2025. The complaint alleges violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder in connection with various public statements made by the Company regarding its business, operations and prospects. The action seeks unspecified damages, costs and expenses, including attorneys’ fees. Once the court appoints a lead plaintiff in the action, the defendants intend to vigorously defend against such allegations. Given the nature of the case, including that the proceedings are in their early stages, the Company is unable to predict the ultimate outcome of the case or estimate the range of potential loss, if any.
