Datadog, Inc. 4

Amit Agarwal converted 40,000 Class B shares into Class A and sold 26,000 Class A shares of Datadog, Inc. for about $7.0 million via a 10b5-1 plan.

On July 30, 2026, Datadog, Inc. insider Amit Agarwal, through family trusts, converted an aggregate 40,000 shares of Class B Common Stock into 40,000 shares of Class A Common Stock at a stated price of $0, then sold 26,000 Class A shares in a series of Rule 10b5-1 plan sales at weighted-average prices between approximately $264 and $269 per share, generating roughly $7.0 million in proceeds. The sales reduced one trust’s Class A position from 21,640 to 16,540 shares (with 6,541 Class A shares still reported separately as indirectly held by trust), while the conversion shifted Class B ownership into the liquid Class A line, leaving the reporting person and related parties with substantial remaining indirect holdings, including large Class A positions held by trusts and the spouse. The transactions appear to be part of ongoing diversification and capitalization of high Class A prices rather than a change in control, and are executed under a pre-established trading plan.
