11. Segment Information

We operate our business in one operating segment, which also represents one reportable segment: life sciences. The life sciences segment focuses on advancing innovative medicines that, in the case of the Company, treat cancer patients that do not respond to, or that have disease progression on, current therapies, through the use of differentiated mechanisms of action including ADCs. The Company’s chief operating decision maker (“CODM”) is the chief executive officer.

The accounting policies of the life sciences segment are the same as those described in Note 2, Summary of Significant Accounting Policies. The CODM assesses performance for the life science segment based on net loss, which is reported on the statements of operations and comprehensive net loss as net loss. The measure of segment assets is reported on the balance sheet as total assets.

To date, the Company has not generated any product revenue. The Company expects to continue to incur significant expenses and operating losses for the foreseeable future as it executes its strategic plan, including completing

the proposed merger transaction, restructuring its activities, managing its legacy assets and obligations and seeking to monetize its legacy programs and intellectual property.  

As such, the CODM uses cash forecast models in deciding how to invest into the life sciences segment. Such cash forecast models are reviewed to assess the entity-wide operating results and performance. Net loss is used to monitor budget versus actual results. Monitoring budgeted versus actual results is used in assessing performance of the segment and in establishing management’s compensation, along with cash forecast models.

The tables below summarize the significant expense categories regularly reviewed by the CODM for the three and six months ended June 30, 2026 and 2025:
