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

What stands out

Tax withholding outweighed market sales: the company withheld $3.5M of officers' and directors' shares for taxes, against $0 sold on the open market. The largest was Daryl Kenningham ($2.6M withheld).Largest withholding, Dec 31, 2025

No officer or director sold shares in this period. 16 are left out

Left out: Lincoln Pereira, Stephen Quinn, Daryl Kenningham, Peter DeLongchamps, Charles Szews, Daniel McHenry, Steven Stanbrook, Michael Jones, Gillian Hobson, Shelley Washburn, Anne Taylor, Melkeya McDuffie, Steven Mizell, MaryAnn Wright, Carin Barth and David Kimbell (share of stake is being verified).

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

"% of total stake" is the shares in an event against all the vested shares the person held that day, across every share class and holding entity, after that day's vesting. "n/a" means the person's holdings are not confirmed, or the row is a purchase. "Holdings record incomplete" means more shares were sold than the filings show the person held that day, so a percentage would be wrong.

Outside holders, reported separately

Conifer Management, L.L.C. reported no open-market sales in the past 12 months. Large shareholders and the funds or companies that board members represent are not part of management, so they are left out of the figures above.

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 uncertainty16 officers and directors not confirmed

Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for Group 1 Automotive Inc are held back until that check is finished. Sales, proceeds, plan and tax status, titles and dates come straight from individual filings and are complete.

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

Sources and methodology1,055 filings on record, 40 filed in the 12-month period, and how we read them

All 1,055 Forms 3, 4 and 5 on record for Group 1 Automotive Inc (SEC CIK 1031203), filed from Feb 3, 2003 to Sep 30, 2026; 40 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 13, 2026. Prices are the ones reported in each filing, often weighted averages. 3 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".
