Unverified record. The outcome below was inferred from the share-price reaction around this date. Nobody has confirmed it against an FDA, SEC or company document, and it may be wrong: we have published at least one inferred outcome that turned out to be impossible (see corrections). Treat it as a price observation, not as a regulatory fact. Verified decisions on this site always link a primary source.

Positioning before the decision
On May 30, 2025, 14 days before the decision date, at-the-money options priced a move of ±6.9% through Jun 20, 2025 (the first listed expiry after the decision; ATM implied volatility 36%). The stock closed -0.1% at the first close across the decision and -2.4% five trading days on. A straddle priced weeks out covers ordinary movement plus the event, so this is the move the options market priced through that expiry, not the event-implied move alone. How this compares across 1,000+ decisions.
