Note 14 – Contingencies

The Company may be party to litigation from time to time in the normal course of business. The Company maintains insurance to cover certain actions and believes that resolution of such litigation will not have a material adverse effect on the Company.

On December 3, 2024, two purported stockholders filed a putative class action against the former officers and directors of Decarbonization Plus Acquisition Corporation III (“DCRC”), including Erik Anderson; Riverstone Holdings, LLC; and related sponsors and entities (the “Hamilton Defendants”) in the Court of Chancery of the State of Delaware (Hamilton et al. v. Anderson et al., C.A. No. 2024-1241-JTL). The lawsuit alleges breach of fiduciary duties and unjust enrichment arising from the merger of Solid Power Operating, Inc. with a subsidiary of DCRC and seeks to recover unspecified damages and equitable relief. None of the Company, its subsidiaries, or its current officers or directors, except Mr. Anderson, is named as a defendant. The Hamilton Defendants have demanded indemnification and advancement of defense costs from the Company. Accordingly, it is reasonably possible that the Company could be liable for the legal fees, defense costs, judgments, and/or settlement fees incurred by certain of the Hamilton Defendants. The proceedings are subject to uncertainties inherent in the litigation process, and the Company cannot currently estimate a reasonably possible loss.
