1) What’s moving the stock
Summit Therapeutics is trading higher today, with the move looking primarily driven by event-driven positioning into the company’s next earnings update.

2) The bigger catalyst investors are tracking
Beyond the earnings print itself, Summit’s valuation remains highly sensitive to ivonescimab development milestones. Market focus has been building around an interim progression-free survival analysis for the HARMONi‑3 squamous cohort expected in Q2 2026, which helps explain why the stock can react even on days without a single headline catalyst.
