Julie Richardson, a director of Datadog, sold a total of 4,363 shares in two transactions: 2,433 shares on 2026-05-07 at $188.50 per share ($458,621) and 1,930 shares on 2026-05-08 at $185.82 per share ($358,633). These were sales (not purchases), typically viewed as routine dispositions rather than a bullish signal.

Key Details

• Transactions: Open market/private sales (code S) on 2026-05-07 and 2026-05-08.
• Prices and proceeds: 2,433 @ $188.50 = $458,621; 1,930 @ $185.82 = $358,633; total ≈ $817,254.
• Plan/footnote: Sales were made pursuant to a 10b5‑1 trading plan dated November 7, 2025 (pre‑arranged automatic sales).
• Ownership correction: The filing corrects prior reports — 2,301 shares previously reported as gifted on Dec 10, 2021 did not occur; this Form 4 amends and restates beneficial ownership reported on Form 4s filed on/after Dec 10, 2021. The corrected post‑transaction beneficial ownership is reported in the filing.
• Timeliness: Form 4 filed 2026-05-11; filing is within the SEC’s two business‑day window for these transactions (timely).

Context
Sales executed under a 10b5‑1 plan are pre‑scheduled and commonly used to avoid questions about timing; they do not necessarily indicate a change in the insider’s view of the company. The filing amends past beneficial‑ownership figures, so check the Form 4 for the updated post‑transaction share balance if you need the exact holding amount.
