The guidance is effective for annual periods beginning after December 15, 2025 and is not expected to have a material impact on the Company’s financial statements.

The update also requires internal-use software to be disclosed under the ASC 360 Property, Plant, and Equipment guidance. The guidance is effective for annual periods beginning after December 15, 2027.

IMG Acquisition On March 3, 2025, the Company completed the acquisition of IMG Energy Solutions, a leading developer of distributed power systems, for cash consideration of approximately $19.6 million, subject to normal closing adjustments and net of cash received (the “IMG Acquisition”). The IMG Acquisition was accounted for under the acquisition method of accounting for business combinations. Accordingly, the Company conducted assessments of the net assets acquired and recognized amounts for identifiable assets acquired and liabilities assumed at their estimated acquisition date fair values, while transaction and integration costs associated with the acquisition were expensed as incurred. In connection with the IMG Acquisition, the Company recorded goodwill and intangible assets of $12.6 million, property and equipment of $5.1 million, other long-term assets of $1.8 million, and net working capital of $0.1 million. Goodwill and intangible assets are recorded in other assets in the accompanying unaudited condensed consolidated balance sheets.
