What stands out

Darren Zeidel sold 78% of vested holdings: 23K shares for $7.8M, 43% under a disclosed plan.Largest sale, Nov 5, 2025

Lester Knight bought 24K shares for $7.8M, first on Feb 10, 2026.Purchase, Sep 2, 2026

Tax withholding outweighed market sales: the company withheld $21.2M of officers' and directors' shares for taxes, against $7.8M sold on the open market. The largest was Gregory Case ($11.1M withheld).Largest withholding, Feb 12, 2026

Percentages cover 17 of 22 officers and directors. 5 are left out

Left out: Gregory Case and Lori Goltermann (holdings couldn't be fully reconciled); Lester Knight (most holdings were last confirmed in 2020); Richard Notebaert (most holdings were last confirmed in 2017); David Debrunner (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 100% of that person's own stake; not comparable between people. The stake is the vested shares held at the start of the period (Oct 9, 2025); the gold part is what they sold.

Common questions

Is the Aon plc CEO selling stock?

No. Gregory Case reported no open-market sales in the past 12 months.

Why are Aon plc insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 43% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 57% had no disclosed plan. A trading plan schedules sales in advance.

Are any Aon plc insiders buying?

Yes. 1 officer or director reported 7 purchases in the past 12 months (Form 4 code P, which includes private purchases).

How much of their stake did Aon plc insiders sell?

About 14% overall. As a group they ended with more shares than they started with. The biggest individual seller, Darren Zeidel, gave up 78% of starting holdings. These figures leave out Gregory Case, the largest holder (holdings couldn't be fully reconciled). That covers the 12 months to Oct 9, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

20 of 22 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (19 exactly, 1 with a minor or footnoted difference). For 2 we show sales but not holdings; the ! icon on their rows explains why. Percentages cover 17 of 22 officers and directors. Left out: Gregory Case and Lori Goltermann (holdings couldn't be fully reconciled); Lester Knight (most holdings were last confirmed in 2020); Richard Notebaert (most holdings were last confirmed in 2017); David Debrunner (held no vested shares at the start). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$7.8M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $7.8M across 22,590 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Disclosed plan · $3.3M · 43%

57%

The lighter segment is sales with no plan disclosed in the filing ($4.4M), including tax-related sales outside a plan.

No plan disclosed · $4.4M

Sales with no 10b5-1 plan and no tax reference in the filing. $4.4M of it is Darren Zeidel. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Darren Zeidel, Nov 5, 2025

Taxes

67,020 shares ($21.2M) were withheld by the company for taxes, which isn't a market sale.

Purchases · 1 buyer (7 trades)

1 officer or director bought shares in this period, in 7 trades(Form 4 code P). Across all their filings on record there are 41 purchase trades.

Charitable gifts · 7.9K shares

Gifts the filings describe as charitable. Gifts are not sales and are not included in the sale totals.

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

Gregory Case: holdings couldn't be fully reconciled (difference of 106,617 shares). Balance changed with no matching transaction and no footnote: +456,956 shares on Feb 12, 2026 (Trust). Filing, Feb 12, 2026

Lori Goltermann: holdings couldn't be fully reconciled (difference of 47 shares). Balance changed without a matching transaction, and the footnote does not state the amount: +23.615 shares on Feb 12, 2026 (Direct). Filing, Feb 12, 2026

Footnote: "Represents Class A Ordinary Shares issued upon the settlement of performance share unit awards originally granted approximately three years ago under the eighteenth cycle of the Company's Leadership Performance Program. The number of shares issued was determined by the Organization and Compensation Committee of the Board of Directors on February 12, 2026, based on the Company's performance for the period from January 1, 2023 to December 31, 2025. | Includes shares acquired under the Aon employee stock purchase plan on December 31, 2025."

Lisa Stevens: minor difference of 47 shares. Difference is under 0.5% of holdings.

Inferred rename: "Trust C" is treated as the same holder as "Trust D", because the old name was never reported again and the new one opened with the same balance (74,802 shares). Old name, new name

Inferred rename: the share class "Common Stock" is treated as the same class as "Class A Ordinary Shares" on 14 holding lines, because the old title was never reported again on those lines and each balance carried over exactly. Example (Edgar Jannotta, 40,152 shares): old title, new title

Inferred typo: the share class "Class A Ordianry Shares" is treated as the same class as "Class A Ordinary Shares" on 1 holding line, because the two spellings are nearly identical and each balance carried over exactly. Example (Lester Knight, 50,000 shares): old title, new title

Inferred typo: the share class "Class A Ordinary Share" is treated as the same class as "Class A Ordinary Shares" on 2 holding lines, because the two spellings are nearly identical and each balance carried over exactly. Example (Stephen McGill, 256,776 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 methodology1,666 filings from SEC EDGAR, and how we read them

All 1,666 Forms 3, 4 and 5 filed for Aon plc (SEC CIK 315293) from Feb 13, 2003 to Sep 3, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages. 6 filings were left out because Aon plc filed them as an owner of another company's stock. 5 older filings exist only on paper and could not be read.

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".
