Under certain utility contracts, the Company periodically receives cash deposits to be held in trust for the payment of energy incentive rebates to be sent directly to the utility’s end-customer on behalf of the utility. The Company acts solely as the utility’s agent to distribute these funds to the end-customer and, accordingly, the Company classifies these contractually restricted funds as restricted cash. Because these funds are held in trust for pass through to the utility’s customers and have no impact on the Company’s working capital or operating cash flows, these cash receipts are presented in the condensed consolidated statement of cash flows as financing cash inflows, “Receipt of restricted cash”, with the subsequent payments classified as financing cash outflows, “Payment of restricted cash.” Equipment and Leasehold Improvements ​

The Company tests its goodwill at least annually for possible impairment.

In addition to the Company’s annual test, it regularly evaluates whether events and circumstances have occurred that may indicate a potential impairment of goodwill. The Company evaluated the current economic environment and noted that it does not believe it is more likely than not that goodwill was impaired as of July 3, 2026. Intangible Assets ​
