Five insiders sold into those gains.

If the Sales Are Planned, the Thesis Survives

The key unknown is whether Slessor's sales, spread across at least two months at ascending price points, operate under a pre-filed 10b5-1 plan, which would indicate routine diversification rather than market-timing judgment. The specific number to watch next quarter is gross margin, currently 46.2%, which in semiconductor equipment cycles tends to compress before revenue does. Run the free FormFactor, Inc. deep-dive →
