16. Business Segments

The Company's chief operating decision maker, or CODM (the Company's Chief Executive Officer), reviews financial information for purposes of assessing business performance and allocating resources, by focusing on the lines of business on a global basis. Effective May 28, 2026, the Company realigned its reportable segments to better serve customers and enhance organizational focus. The Company realigned its previous four operating segments into three operating segments under ASC 280, Segment Reporting as follows:

•Network & Infrastructure Solutions (NIS) — providing power solutions and services to broadband, telecommunications, data center, and industrial utility customers.

•Industrial Mobility Solutions (IMS)— providing power for electric industrial forklifts, and other material handling equipment as well as transportation applications, primarily Class 8 trucks.

•Precision Power Solutions (PPS) — providing energy solutions primarily for military vehicles, advanced defense programs, soldier powering and autonomous systems.

The operating segments of NIS, IMS, and PPS also represent the Company's reportable segments under ASC 280, Segment Reporting. All prior comparative periods presented have been recast to conform to these changes.

The following table presents summarized financial information for the reportable segments at July 5, 2026 and June 29, 2025. The Company does not allocate assets to its segments as the CODM does not evaluate the performance of segments using asset information.

(1)Reportable segments do not record inter-segment revenues and accordingly there are none to report.

(2)The Company does not allocate interest expense or other (income) expense, net, to the reportable segments.

(3) Corporate and other unallocated includes amounts managed on a company-wide basis and not directly allocated to any reportable segments, primarily relating to IRC 45X production tax credits and refunds of IEEPA tariffs recognized relating to amounts paid in prior periods. Also, included are start-up costs for exploration of a new lithium plant.
