Segment Reporting

6 Months Ended

Jun. 30, 2025

12. Segment Reporting

The Company operates and is managed as a single operating segment. The measure of segment assets is reported on the consolidated balance sheets as total assets. All assets are in the United States and there has been no revenue generated through June 30, 2025. The accounting policies of the segment are the same as those described in Note 2.

The determination of a single operating segment is consistent with the consolidated financial information regularly reviewed by the CODM, which is used in assessing segment performance and deciding how to allocate resources on a consolidated basis. The CODM assesses segment performance and makes decisions on how to allocate resources based on consolidated net loss reported on the consolidated statements of operations and comprehensive loss. In assessing performance, the CODM reviews net loss in comparison to budget.

The following table presents information about reported significant segment expenses:
