MONSER EDWARD L 4

What Happened

• Edward L. Monser, a director of Vertiv Holdings Co. (VRT), exercised stock options to acquire 77,294 shares (two exercises of 38,647 shares each) and sold the same 77,294 shares in multiple open‑market transactions on March 6, 2026.
• Exercise costs: 38,647 shares @ $12.05 = $465,696 and 38,647 shares @ $20.56 = $794,582 (total exercise cost ≈ $1,260,278). Sale proceeds: multiple trades at prices ranging roughly $239.34–$250.46, totaling approximately $18.97 million in gross proceeds.
• These sales are routine insider sales (dispositions) rather than purchases; the exercised shares were immediately sold, effectively a cash‑out of vested option value.

Key Details

• Transaction date: March 6, 2026; Form 4 filed March 9, 2026 (reporting date matches filing).
• Option exercises: 77,294 shares acquired via exercise (transaction code M); options were fully vested as of the date (footnote F15).
• Open‑market sales: 77,294 shares sold in multiple trades at prices from about $239.34 to $250.46 across many lots; aggregated proceeds ≈ $18.97M.
• Net share change: 0 (acquired 77,294 via exercise and disposed of 77,294 via sale).
• Notable footnotes: sales were automatically effected under a Rule 10b5‑1 trading plan adopted Dec 5, 2025 (F1). Several footnotes (F2–F13) group sales into price ranges; the filer will provide a price‑by‑price breakdown on request. F14 notes some securities are held by the reporting person’s spouse.
• Filing timeliness: filing date is March 9, 2026 for transactions on March 6, 2026; no late‑filing flag was provided in the supplied data.

Context

• This was an exercise of options followed by immediate sales (common "exercise-and-sell" or cash‑out). The economics: modest exercise cost ($1.26M) vs. large sale proceeds ($19.0M).
• The trades were executed under a pre‑arranged 10b5‑1 plan, which typically schedules sales at predetermined times/levels and reduces the likelihood the sales reflect contemporaneous insider sentiment.
• For retail investors: purchases generally carry more direct informational weight than planned sales; these transactions largely converted vested option value into cash under an automated plan.
