The filing notes that each reported price is a weighted average and that full per-share detail is available upon request to the SEC, the issuer, or security holders.

All sales were executed under a Rule 10b5-1 plan established on December 15, 2025. The filing also notes that each share of Class B Common Stock is convertible at the option of the holder into one share of Class A Common Stock at any time, and converts automatically upon transfer (subject to permitted transfers), the holder's death, or the tenth anniversary of Datadog's initial public offering.
