What stands out

Steven Reinemund sold 59% of vested holdings: 100K shares for $25.4M, none under a disclosed plan.Largest sale, Feb 26, 2026

Four insiders sold $79.0M with no disclosed plan: Roger Fradin ($51.4M), David Cote ($10.2M) and Jan Dokkum ($9.8M), plus 1 more. The filings don't state a reason.Roger Fradin: largest such sale, Feb 26, 2026 · David Cote: largest such sale, Feb 26, 2026 · Jan Dokkum: largest such sale, Feb 26, 2026

Percentages cover 14 of 26 officers and directors. 12 are left out

Left out: Roger Fradin and Michael Giresi (holdings couldn't be fully reconciled); David Cote (most holdings were last confirmed in 2023); Edward Monser, Jan Dokkum and Anders Karlborg (most of their shares vested during the period, so a percentage would mislead); Matthew Louie, Jacob Kotzubei, Craig Chamberlin, Ying He and Michael Resha (held no vested shares at the start); Joseph Deangelo (most holdings were last confirmed in 2022).

Disclosed company stock is not an insider's whole wealth.

Who sold, and how much of their stake

Officers and directors, past 12 months. Each bar is the insider's vested stake at the start of the period (Oct 8, 2025). The gold part is what they sold.

Common questions

Is the Vertiv CEO selling stock?

No. Giordano Albertazzi reported no open-market sales in the past 12 months.

Why are Vertiv insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 18% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 82% had no disclosed plan. A trading plan schedules sales in advance.

Are any Vertiv insiders buying?

No. Officers and directors reported no purchases in the past 12 months.

How much of their stake did Vertiv insiders sell?

About 24% overall. As a group they still hold 71% of their starting shares. The biggest seller whose stake can be measured, Steven Reinemund, gave up 59% of starting holdings. These figures leave out David Cote, the largest holder (most holdings were last confirmed in 2023). That covers the 12 months to Oct 8, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

24 of 26 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (16 exactly, 8 with a minor or footnoted difference). For 2 we show sales but not holdings; the ! icon on their rows explains why. Percentages cover 14 of 26 officers and directors. Left out: Roger Fradin and Michael Giresi (holdings couldn't be fully reconciled); David Cote (most holdings were last confirmed in 2023); Edward Monser, Jan Dokkum and Anders Karlborg (most of their shares vested during the period, so a percentage would mislead); Matthew Louie, Jacob Kotzubei, Craig Chamberlin, Ying He and Michael Resha (held no vested shares at the start); Joseph Deangelo (most holdings were last confirmed in 2022). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$128M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $128M across 510,549 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Disclosed plan · $22.9M · 18%

82%

The lighter segment is sales with no plan disclosed in the filing ($105M), including tax-related sales outside a plan.

No plan disclosed · $105M

Sales with no 10b5-1 plan and no tax reference in the filing. $51.4M of it is Roger Fradin. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Roger Fradin, Feb 26, 2026

Taxes

10,925 shares ($2.3M) were withheld by the company for taxes, which isn't a market sale.

Less than usual: about one-sixth of the 5-year average. 7 insiders sold; the average is 4 a year.

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. A sale that an outside holder also reports (a family trust, a fund) is counted with outside holders in every year. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.

Known gaps and uncertainty2 insiders whose holdings couldn't be fully reconciled

Roger Fradin: holdings couldn't be fully reconciled (difference of 36,626 shares). Balance changed without a matching transaction, and the footnote does not state the amount: +18,313 shares on Dec 19, 2025 (Direct). Filing, Dec 19, 2025

Footnote: "The Reporting Person previously directly beneficially owned these shares of Class A Common Stock. On December 19, 2025, the Reporting Person gifted the Class A Common Stock to the R VRT GRAT 2025 II, of which the Reporting Person is the trustee and annuitant and which is for the benefit of the Reporting Person and the Reporting Person's children, and over which securities the Reporting Person maintains indirect beneficial ownership. As of the date of this Form 4, these securities have not been sold and remain held by the R VRT GRAT 2025 II."

Michael Giresi: holdings couldn't be fully reconciled (difference of 18 shares). Balance changed without a matching transaction, and the footnote does not state the amount: -0.88 shares on Jan 15, 2026 (Direct). Filing, Jan 15, 2026

Footnote: "Represents the automatic withholding by the issuer to satisfy the reporting person's tax obligation upon vesting and settlement of restricted stock units ("RSUs"), including dividend-equivalent stock units ("DSUs"). Pursuant to the terms of the 2020 Stock Incentive Plan, fractional shares are mandatorily settled in cash. | Includes shares."

Stephanie Gill: minor difference of 30 shares. Difference is under 0.5% of holdings.

Anders Karlborg: minor difference of 45 shares. Difference is under 0.5% of holdings.

Anand Sanghi: minor difference of 185 shares. Footnote reports an exempt acquisition without its size; amount derived from the balance change.

Scott Armul: minor difference of 29 shares. Difference is under 0.5% of holdings.

Frank Poncheri: minor difference of 19 shares. Footnote reports an exempt acquisition without its size; amount derived from the balance change.

Wei Shen: minor difference of 24 shares. Footnote reports an exempt acquisition without its size; amount derived from the balance change.

Eric Johnson: minor difference of 42 shares. Footnote reports an exempt acquisition without its size; amount derived from the balance change.

Craig Chamberlin: minor difference of 94 shares. Footnote reports an exempt acquisition without its size; amount derived from the balance change.

Inferred rename: the share class "Common Stock" is treated as the same class as "Class A Common Stock" on 10 holding lines, because the old title was never reported again on those lines and each balance carried over exactly. Example (David Fallon, 227,387 shares): old title, new title

Inferred rename: the share class "Class A common stock" is treated as the same class as "Common Stock" on 1 holding line, because the old title was never reported again on those lines and each balance carried over exactly. Example (Colin Flannery, 17,825 shares): old title, new title

External context: we only cite outside events when a documented connection exists. None is shown for this period.

Sources and methodology513 filings from SEC EDGAR, and how we read them

All 513 Forms 3, 4 and 5 filed for Vertiv (SEC CIK 1674101) from Jun 7, 2018 to Oct 6, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages.

Probable 2-for-1 stock split on or before Jun 8, 2018 (split date stated in a footnote). Splits aren't reported as transactions; 3 holding lines changed by exactly this ratio, so earlier share counts are restated.

Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.

Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
