Amit Agarwal converted 40,000 Datadog Class B shares into Class A and sold 26,000 Class A shares via family trusts for about $6.7 million under a 10b5-1 plan.

On July 16, 2026, Datadog, Inc. insider Amit Agarwal, through family trusts, converted a total of 40,000 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 March 13, 2026, sold 26,000 Class A shares in a series of open-market transactions at weighted-average prices between approximately $254.79 and $265.53 per share, generating gross proceeds of roughly $6.7 million. The transactions were effected indirectly by the Agarwal 2018 and 2019 Family Trusts (with his spouse as trustee), and left significant remaining indirect holdings: hundreds of thousands of Class A-equivalent shares via trust-held Class A and Class B stock plus additional Class A shares held by his spouse, indicating these trades represent a sizable but partial liquidity event rather than a full exit of his economic interest.
