Analysis · FSLY · Technology
Fastly CTO Artur Bergman sold $11.4 million of Class A common stock on September 23 under a pre-existing 10b5-1 plan adopted in June. The sale is roughly 3.5x larger than the $3.2 million he noticed in a Form 144 on September 14, making this a materially larger disposition than the market was led to expect. It extends a broad insider selling pattern at Fastly — seven insiders have sold over $21 million in the last 90 days with zero open-market purchases. Bergman remains a significant holder with over 1.5 million shares post-sale, but the scale of this transaction and the one-sided insider activity are notable for a company whose stock has been under pressure.
