Almstead Neil Gregory

Neil Gregory Almstead, an insider at PTC Therapeutics (PTCT), has filed 280 Form 4 transactions since 2014, disposing of 689,513 shares against zero ever bought on the open market. His activity over the two weeks from June 26 through July 9, 2026 shows a strikingly mechanical pattern: every single option exercise was sold in full on the same day, with no shares retained. On 2026-07-07, he exercised 24,613 shares at a $39.42 strike price and sold all 24,613 the same day across three trades at $87.17 to $89.44. On 2026-07-06, he exercised 22,161 shares at $38.10-$39.42 and sold all 22,161 the same day at $85.28 to $87.03. The same full-exercise-to-full-sale pattern repeated on June 26 (8,130 shares) and July 9 (2,464 shares, at a $46.54 strike sold immediately at $90.25) — roughly 57,000 shares cashed out in a two-week span, every one of them sold the same day it was exercised. Sale prices climbed steadily across the window, from the mid-$80s on June 26 to over $90 by July 9, and Almstead kept selling at each higher level rather than pausing — the hallmark of a pre-scheduled, non-discretionary trading plan rather than opportunistic timing.
