OMC insider ownership: who sold, why, and what they still hold

Who	Shares	Price	% of total stake	Total stake after	Trade date	Filed
Linda Rice Director	1,385	$88.73	11%	11K	Aug 24, 2026	Aug 26, 2026

What stands out

Linda Rice sold 2.7K shares (23% of starting holdings), but 3.1K more vested, so the stake grew (from 12K to 13K).Largest sale, Aug 24, 2026

Tax withholding outweighed market sales: the company withheld $8.0M of officers' and directors' shares for taxes, against $238K sold on the open market. The largest was John Wren ($3.2M withheld).Largest withholding, May 22, 2026

Percentages cover 14 of 18 officers and directors. 4 are left out

Left out: John Wren (most holdings were last confirmed in 2022); Philippe Krakowsky, Lee Wyatt and Patrick Moore (held no vested shares at the start).

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 Omnicom Group CEO selling stock?

No. John Wren reported no open-market sales in the past 12 months.

Why are Omnicom Group insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 0% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 100% had no disclosed plan. A trading plan schedules sales in advance.

Are any Omnicom Group insiders buying?

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

How much of their stake did Omnicom Group insiders sell?

About 0.3% overall. As a group they ended with more shares than they started with. The biggest individual seller, Linda Rice, sold shares equal to 23% of starting holdings, but more vested, so the stake grew. These figures leave out John Wren, the largest holder (most holdings were last confirmed in 2022). 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.

18 of 18 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (3 exactly, 15 with a minor or footnoted difference). Percentages cover 14 of 18 officers and directors.

"Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$238K of sales by plan status, purpose, seller and month

Officer and director open-market sales: $238K across 2,733 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

No plan disclosed · $238K

Sales with no 10b5-1 plan and no tax reference in the filing. $238K of it is Linda Rice. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Linda Rice, Aug 24, 2026

Taxes

107,139 shares ($8.0M) were withheld by the company for taxes, which isn't a market sale.

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.

Inferred rename: "See fn" is treated as the same holder as "GRATs", because the old name was never reported again and the new one opened with the same balance (516,315 shares). Old name, new name

Inferred typo: the share class "Common Stock $0.15 Par Value" is treated as the same class as "Common Stock, $0.15 Par Value" on 1 holding line, because the two spellings are nearly identical and each balance carried over exactly. Example (Allen Rosenshine, 454,080 shares): old title, new title

Inferred typo: the share class "Common Stock Par Value $0.15" is treated as the same class as "Common Stock, Par Value $0.15" on 6 holding lines, because the two spellings are nearly identical and each balance carried over exactly. Example (John Murphy, 10,626 shares): old title, new title

Inferred typo: the share class "Common Stock par value $0.15 per share" is treated as the same class as "Common Stock, par value $0.15 per share" on 2 holding lines, because the two spellings are nearly identical and each balance carried over exactly.

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

Sources and methodology1,509 filings from SEC EDGAR, and how we read them

All 1,509 Forms 3, 4 and 5 filed for Omnicom Group (SEC CIK 29989) from Oct 8, 1999 to Oct 5, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages. 7 older filings exist only on paper and could not be read.

Probable 2-for-1 stock split on or before Jun 25, 2007 (split date stated in a footnote). Splits aren't reported as transactions; 6 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".
