From time to time, we are involved in legal proceedings and subject to claims arising both inside and outside the ordinary course of business. During the year ended December 31, 2025, the Company received a $1.4 million complaint from a trustee in a third-party bankruptcy proceeding seeking recovery of amounts paid for various purchases made on the Company’s platform after the commencement of the bankruptcy proceedings. This complaint is similar to hundreds of other similar cases commenced in connection with the bankruptcy proceeding, and we intend to defend against the trustee’s claim vigorously. The results of this claim, and other litigation and claims in the ordinary course, cannot be predicted with certainty, and the Company does not believe potential losses are estimable or probable at this time. Even if any particular litigation or claim is not resolved in a manner that is adverse to our interests, such litigation can have a negative impact on us because of defense and settlement costs, diversion of management resources from our business, and other factors.
