Segment Reporting
The Company operates as one operating segment. The Company's chief operating decision maker, or CODM, is its chief executive officer, who reviews financial information presented on a consolidated basis. The CODM manages and allocates resources to the operations of the Company on a total company basis by assessing the overall level of resources available and how to best deploy these resources across functions and research and development projects that are in line with our long-term company-wide strategic goals. Consistent with this decision-making process, the CODM uses operating expenses to monitor budget versus actual results for purposes of evaluating performance and to make decisions about the allocation of resources. The CODM does not utilize revenue in their decision-making process as a significant amount of the revenues recognized by the Company are derived from the upfront payments received from our collaboration partners (see Footnote 8 for further details).
The financial metrics used by the CODM to make key operating decisions consist of development, research, and general and administrative expenses.

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.
