Segment Information
The Company’s Chief Executive Officer has been identified as the chief operating decision maker (CODM). The CODM reviews the Company’s operating results on a consolidated basis for purposes of allocating resources and evaluating financial performance. Specifically, the CODM evaluates the Company’s financial performance and decides how to allocate resources based on consolidated net income (loss), which enables the CODM to assess both the overall level of resources available and optimize distribution of resources across functions, product lines, regions and research and development programs in line with our long-term corporate-wide strategic goals. The CODM also reviews disaggregated revenue by product line, geographic regions, and industry (see Note 3).
The following table presents entity-wide significant expense categories and net loss details provided to the CODM:

About Segments Disclosures

Segment disclosures break a company into its reportable operating units, revealing revenue, profit, and asset allocation that consolidated financial statements obscure. Under ASC 280, segments must match how the chief operating decision maker views the business, providing a window into internal management structure and resource allocation priorities.

Key signals: compare segment margins to identify which units drive profitability and which destroy value. Watch for changes in the number of reportable segments — segment aggregation or disaggregation often coincides with strategic shifts or attempts to obscure declining performance. Intersegment elimination patterns reveal internal pricing practices. The reconciliation between segment totals and consolidated figures exposes corporate overhead allocation and unallocated items. Geographic revenue concentration highlights regulatory and currency exposure. Compare segment-level capital expenditure against segment revenue to assess where management is investing for future growth versus harvesting existing assets.
