Monia Brett P (CEO) sold 160.8K shares for $12.1M across 5 transactions in March 2026; stock down 11.8% in 30 days post-sale.
Monia Brett P, Chief Executive Officer of Ionis Pharmaceuticals, executed 5 separate sales totaling 160,773 shares for $12,114,155.19 at blended average price of $75.35 on March 9–10, 2026. This represents a 39.9% reduction in her pre-transaction holdings of 403,435 shares, leaving post-transaction holdings of 242,662 shares. The timing is notable: the stock has declined 11.8% in the 30 days since the sale and is currently trading at $74.79, down 13.5% from its 52-week high of $86.50. The CEO's prior trades at Ionis show mixed outcomes—two completed 90-day periods both posted positive returns (+33.2% and +35.2%), meaning those prior sales were poorly timed relative to subsequent stock performance. Ionis is currently unprofitable (annual net income negative at $-128,606,000.00) despite 33.8% annual revenue growth, a fundamental context that may contextualize the magnitude of this substantial position reduction.
