From time to time, the Company is involved in various lawsuits, claims, inquiries and other regulatory and compliance matters, most of which are routine to the nature of the Company’s business.

Additional lawsuits, claims, inquiries and other regulatory and compliance matters could arise in the future. The range of expenses for resolving any future matters would be assessed as they arise; until then, a range of potential expenses for such resolution cannot be determined.

Based upon current information, the Company concluded that the impact of the resolution of these matters would not be, individually or in the aggregate, material to the Company’s financial position, results of operations or cash flows.

The Company provides warranties for EPC and O&M projects, guaranteeing the work performed against defects in equipment, materials, design, or workmanship. The length of the warranty period is generally two years. Materials and equipment used in construction are either provided by the customers or warranted against defects by suppliers. The warranty claims that the Company historically received have not been substantial.

In February 2026, the U.S. Supreme Court issued a ruling invalidating certain tariffs previously imposed under the International Emergency Economic Powers Act (IEEPA). We are evaluating the impacts of these developments on our results of operations. We will continue to monitor recent developments on tariff policy and evaluate any changes to the applicability of tariffs to our business as they occur. As of March 31, 2026, we have not recorded any impact for potential recovery of tariff-related costs as refunds are uncertain.
