GE HealthCare is trading at $69.39, up +8.20%, with no verified company-specific announcement dated September 18, 2026 explaining the after-hours surge.
- Earlier reports said GE HealthCare was discussing a possible $1 billion acquisition of Sofie Biosciences, but the talks were unconfirmed and reported September 13.
- Broader markets were mixed: the Nasdaq Composite rose 0.80% and the S&P 500 0.28%, insufficient to clearly explain the unusually large move. The catalyst may emerge after the alert window.
