Yes. Joseph Fadool sold 29K shares ($2.0M) in the past 12 months, none of it under a trading plan disclosed in the filings.
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.
Yes. 1 officer or director reported 1 purchase in the past 12 months (Form 4 code P; rows the filings describe as reinvested dividends, plan purchases, private deals or moves into the person's own trust are not counted).

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.
Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for Borgwarner 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.
All 1,688 Forms 3, 4 and 5 on record for Borgwarner Inc (SEC CIK 908255), filed from Aug 27, 1997 to Sep 1, 2026; 74 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 16, 2026. Prices are the ones reported in each filing, often weighted averages. 9 filings were left out because Borgwarner Inc filed them as an owner of another company's stock. 227 older filings exist only on paper and could not be read.
Probable 2-for-1 stock split on or before Feb 6, 2008 (first filing that shows post-split balances). Splits aren't reported as transactions; 5 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".
