CTO Alexis Le-Quoc converted 43,224 Datadog Class B shares into Class A and sold 42,224 Class A shares in multiple trades on July 20, 2026 for about $11.1 million under a 10b5-1 plan.

On July 20, 2026, Datadog, Inc. Chief Technology Officer Alexis Le-Quoc converted 43,224 shares of Class B Common Stock into Class A Common Stock at no cost and, pursuant to a pre-arranged Rule 10b5-1 trading plan dated June 13, 2025, executed a series of open-market sales of Class A Common Stock totaling 42,224 shares at weighted-average prices ranging from approximately $258.86 to $267.95 per share. The gross sale proceeds are approximately $11.1 million, calculated from the reported per-share prices. Following these transactions, Le-Quoc continues to hold 509,805 shares of Class A Common Stock directly and an additional 6,146,835 shares of Class A Common Stock indirectly through the Alexis Le-Quoc Revocable Trust (after conversion from Class B), implying a post-transaction equity position worth roughly $1.79 billion based on the transaction price range. The Class B shares are fully convertible into Class A on a one-for-one basis with no expiration, and the sales appear to be part of an ongoing liquidity and diversification program rather than a full exit, given the substantial remaining ownership and use of a 10b5-1 plan.
