SEGMENT REPORTING
Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (CODM) in deciding how to allocate resources to an individual segment and in assessing performance. The Company operates as a single reporting segment, focused on the development of MasterKey therapies that target families of oncogenic mutations in patients with cancer. The accounting policies of the single operating segment are identical to those described in Note 2.
The Company’s measure of segment profit or loss is net loss. The CODM is the chief executive officer (CEO). The CODM manages and allocates resources to the operations of the Company on a total company basis. Managing and allocating resources on a consolidated basis enables the CEO to assess the overall level of resources available and how to best deploy these resources across functions and development projects that are in line with the Company’s strategic goals. Consistent with this decision-making process, the CEO uses consolidated financial information for purposes of evaluating performance, forecasting future period financial results, allocating resources and setting incentive targets. Segment net loss is used to monitor budget versus actual results and in assessing performance of the segment.
The following table is a reconciliation of the significant expense categories to segment net loss regularly provided to the CODM when managing the Company’s single reporting segment: | | | | | | | | | | | |

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.
