TWST Twist Bioscience Corp
Price Chart
Executive Summary
Four insiders at Twist Bioscience sold a total of $1.31M in open-market sales over a 7-day window, including the CEO (via option exercise and sale) and the CFO. The cluster is dominated by a single large sale by Cho Dennis ($991K), and the total represents ~0.03% of market cap — well below the 0.1% threshold for materiality. The CEO's sales are tied to derivative exercises, a common liquidity pattern. This is a routine, low-significance cluster.
