Corrigan Catherine

On May 15, 2026, Catherine Corrigan's routine Exponent stock sale landed at $54.0595 — the low point in a real price swing traced entirely through her own monthly transactions. Zoom out and the full path is visible: $67.6964 in April, down to that $54.06 May low, then a recovery to $57.1263 in June and $62.7776 by July — a roughly 20% drop followed by a partial rebound over three months. Underneath that price trail sits a rigid, twin-tranche mechanism: two fixed-strike option exercises, one at $29.05 and one at $25.405, repeating almost every month like clockwork, each immediately converted to a same-day market sale. Across 184 transactions since 2013, Corrigan has sold 162,136 Exponent shares and never once made an open-market purchase.
