Datadog CTO Alexis Le-Quoc exercised options and converted Class B into Class A shares, then sold about 40,009 Class A shares of Datadog, Inc. under a 10b5-1 plan for roughly $10.4 million while retaining a very large remaining stake.

On July 8, 2026, Datadog, Inc. Chief Technology Officer Alexis Le-Quoc, through the Alexis Le-Quoc Revocable Trust, effected a series of transactions involving both derivative and non-derivative securities. A stock option for 18,750 shares with a $10.74 exercise price was partially exercised (code M), delivering 18,750 shares of Class B Common Stock and then converting those into 18,750 shares of Class A Common Stock. In addition, there were conversions of Class B into Class A Common Stock totaling 43,224 and 10,688 shares (code C), both treated as acquisitions of Class A shares. On the same date, Le-Quoc executed a pre-arranged 10b5-1 trading plan selling multiple blocks of Class A Common Stock in open-market transactions at weighted-average prices between approximately $251.46 and $261.46, for 40,009 shares in aggregate. After these trades and conversions, the trust directly held 509,805 shares of Class A Common Stock and 2,360,026 shares of Class B Common Stock, plus 6,146,835 shares of Class A Common Stock held indirectly by the trust, implying a substantial remaining equity stake. Based on the sale prices around $260 per share, the open-market sales totaled roughly $10.4 million, and the post-transaction equity value appears to exceed $2.3 billion, reflecting the large continuing ownership position.
