Summit Therapeutics posted a steep GAAP net loss for Q2 2025, primarily due to a $466.6 million non-cash stock-based compensation expense from a stock option modification. Non-GAAP figures showed increased R&D and G&A spending as the company advanced its ivonescimab clinical programs.
GAAP operating expenses surged to $568.4 million, largely from a one-time $466.6 million non-cash stock-based compensation expense.
Non-GAAP operating expenses rose to $89.6 million, reflecting expanded clinical trials for ivonescimab.
GAAP net loss widened to $565.7 million, or $(0.76) per share, while non-GAAP net loss was $86.9 million, or $(0.12) per share.
Cash and short-term investments totaled $297.9 million at quarter end.
Summit will continue advancing its Phase III ivonescimab trials and is considering filing a BLA for ivonescimab plus chemotherapy based on HARMONi results.
