Data to the close of October 19, 2026 (ET). Sources checked October 20, 2026.

Silence Therapeutics (SLN) announced a signed agreement for a cash acquisition at $20.00 per American Depositary Share (ADS). A cash offer changes the question behind a stock chart: the quoted price can become closely tied to a contractual payment, a timetable and conditions that have not yet been met.
