Datadog, Inc. (DDOG) Form 4 filed for Olivier Pomel reports multiple transactions on 09/08/2025 showing option exercise, conversions and open-market sales. The reporting person exercised a 38,118-share stock option with $0.9092 exercise price and holds 952,938 Class B shares after the exercise. The filing shows conversions/acquisitions labeled C(1) for 21,728 and 11,195 Class A shares and sales labeled S(2) of 16,073, 16,550 and 300 Class A shares at weighted-average prices of approximately $135.31, $136.14 and $136.82, respectively. Post-transactions, reported Class A ownership figures are provided in the table.

Positive

• Exercise of vested options (38,118 shares) indicating the reporting person fulfilled compensation-related actions with a nominal exercise price of $0.9092
• Use of a 10b5-1 plan (dated September 13, 2024) for sales, which provides an affirmative defense framework for scheduled insider transactions
• Clear disclosure of weighted-average sale prices and offer to provide per-price breakdowns upon request, supporting transparency

Negative

• Insider sold Class A shares (16,073; 16,550; 300) reducing reported Class A holdings, which could be viewed as insider liquidity rather than accumulation
• Significant volume of shares sold across multiple price bands (prices ranged from roughly $134.70 to $136.88), which may modestly increase circulating supply from insider holdings

Insights

Securities Analyst

TL;DR: Insider exercised options, converted shares and executed planned sales under a 10b5-1 plan, reducing some Class A holdings while increasing exercised option-based ownership.

The filing documents a fully vested option exercise of 38,118 shares at a $0.9092 strike, increasing direct beneficial ownership of Class B shares to 952,938. Several blocks of Class A shares were sold pursuant to a 10b5-1 plan dated September 13, 2024, with reported weighted-average sale prices in the $134.70–$136.88 ranges. Conversions labeled C(1) reflect convertible Class B/Class A mechanics described in the explanation. Transactions appear routine given the presence of an established 10b5-1 plan and an exercise of vested options; the filing does not disclose any new compensation grants or material changes to governance.

Corporate Governance Expert

TL;DR: Actions are consistent with standard insider liquidity and option exercise; no governance red flags disclosed in the form.

The report includes automatic/optional conversions of Class B into Class A and scheduled sales under a documented 10b5-1 plan. The explanation clarifies conversion mechanics and the 10b5-1 plan date, which supports an affirmative defense for the sales. No departures, new appointments, or extraordinary transfers are reported. The filing is procedural and informative for share-count tracking rather than indicating governance change.
