DOKKUM JAN VAN 4

What Happened
Jan van Dokkum, a director of Vertiv Holdings Co (VRT), exercised 38,647 stock options at $20.56 per share (cost ~ $794,582) on 2026-02-26 and sold a total of 77,294 shares that same day. The open‑market sales consisted of 22,989 shares at a weighted average price of $254.49 (proceeds ~$5,850,471) and 15,658 shares at a weighted average price of $255.42 (proceeds ~$3,999,366). The filing also shows the 38,647 shares acquired on exercise were disposed (reported as a derivative disposition at the $20.56 option price). Open‑market sale proceeds sum to roughly $9.85 million. This was an exercise-plus-sale transaction (exercise of options followed by sales), which is often a cashless exercise and sale.

Context

• This was an option exercise with same‑day sales (a cashless or sell‑to‑cover pattern): the insider exercised vested options and sold shares the same day—common for exercising compensation awards to cover costs/taxes or to take gains.
• Sales are routine insider transactions and do not by themselves indicate company performance; purchases are typically more informative about insider confidence.
• The filing contains standard vesting details for past option grants; nothing in the filing indicates a 10% owner filing or a gift/award separate from the exercised options.
