Segment Reporting Segment Reporting
The Company’s chief operating decision-maker (“CODM”) is its Chief Executive Officer and President. Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the CODM in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources and evaluating financial performance. As such, the Company has determined that it operates in one operating and one reportable segment.
The Company designs, develops, manufactures and markets innovative zinc-based energy storage solutions for utility-scale, microgrid and commercial & industrial (C&I) applications. The Company operates and holds long-lived assets in a single geographical region.
The CODM reviews financial information on a consolidated basis and uses Gross profit (loss) and Net income (loss) to assess financial performance considering budget-to-actual variances when making key decisions on how to allocate company resources.
The Company’s segment information is summarized as follows:
