AstraZeneca’s $2 Billion Vote of Confidence Leaves Summit Therapeutics Trading Well Below Street Targets
AstraZeneca (AZN) will invest $2B in Summit Therapeutics (SMMT) via preferred stock convertible at $18.36/share, a 18.6% premium to Summit's prior close. Summit shares rose 5.88% on the news. The deal includes a trial collaboration but no licensing rights. Summit has no revenue, and its value hinges on ivonescimab, its sole drug. Citi raised its target to $43, citing validation of ivonescimab. The FDA decision on ivonescimab is due by November 2026.
