Actionable Insight ▼ Bearish

The CEO's large open-market sale without a 10b5-1 plan is a bearish signal. Monitor for any subsequent 8-K filings or earnings pre-announcements that could explain the timing. The small CTO sale is likely routine and not informative.

Executive Summary

Fastly CEO Charles Lacey III sold $1.26M worth of shares on September 14, 2026, at ~$24.93, while CTO Artur Bergman made a small $10K sale on September 9. The CEO sale is material relative to the company's market cap (~$326M) at ~0.4%, but the CTO sale is trivial. No 10b5-1 plan is indicated, and the CEO sale is an open-market transaction, which is a bearish signal given the size and seniority.
