Segment Information
The Company operates in a single operating segment and has one reportable segment, which includes all activities related to the discovery, development and manufacturing of its product candidates. The determination of a single segment is consistent with the consolidated financial information regularly provided to the Company’s chief operating decision maker (“CODM”). The Company’s CODM is its chief executive officer. The CODM, in alignment with the Company’s strategic goals, uses consolidated net loss to monitor budget to actual results and cash forecast models for assessing performance and making operating decisions. The measurement of segment assets is reported on the consolidated balance sheet as total assets.

The Company’s significant segment expenses are as follows (in thousands):

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.
