Segment Reporting
The Company operates in one operating segment and therefore has only one reportable segment. The Company derives revenue primarily from sales of its commercial products in the U.S.

The Company's chief operating decision maker (CODM) is the chief executive officer. The Company manages the business activities on a consolidated basis. The CODM assesses performance of the Company, and decides how to allocate resources based on net earnings (loss), which is reported in the consolidated statement of earnings (loss) as Net earnings (loss)
and allocates resources on a consolidated basis. The CODM uses net earnings (loss) to decide whether to reinvest profits into the Company's current products or into other research and development initiatives for the Company's product candidates. Net earnings (loss) is also used to monitor budget versus actual results.

The measure of the reportable segment assets is reported on the balance sheet as total assets.

The accounting policies of the reportable segment are the same as those described in Note 2, Summary of Significant Accounting Policies.

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.
