Datadog, Inc. 4

Datadog CFO David M. Obstler reclassified and transferred 7,500 shares between Class B and Class A stock and related trusts with no reported purchase or sale for value.

On June 12, 2026, Datadog, Inc. Chief Financial Officer David M. Obstler reported an internal reclassification of 7,500 shares between Datadog’s dual‑class stock structures and a related transfer to an indirect trust holding, with no cash consideration involved. The Form 4 shows a conversion code “C” for 7,500 shares of Class B Common Stock into Class A Common Stock and a corresponding “G” transaction (bona fide gift/transfer) of 7,500 Class A shares, consistent with trust-related estate/wealth planning rather than an open‑market trade. After these movements, Obstler directly holds 434,591 Class A shares, and additional Class A shares are held indirectly in two Obstler Children 2019 Trusts (each holding 46,199 and 46,198 Class A shares, respectively), with the Class B shares fully convertible into Class A on a one‑for‑one basis and no expiration. Because no prices or consideration are reported and the transactions appear purely structural and for family trust purposes, they are best interpreted as neutral, non‑economic insider activity rather than a directional signal about the issuer’s stock.
