Beta99% was sold under disclosed trading plans, 1% with no plan disclosed. The largest seller, Stephen Kelley (President and CEO, Director), sold $15.8M.Share-of-stake figures for this company are being verified and will be added when that check is finished. Why
Price note. One filing reports a price of $13,002.00, about 920 times the same filer's other prices that week; it appears to be a decimal error for about $13.00, so we've excluded it from totals. Filing
Routine activity: 99% of sales were under disclosed plans, and no insider sold more than 1% of vested holdings.
A share of stake is shown for 0 of the 10 officers and directors who sold. 15 are left out Disclosed company stock is not an insider's whole wealth.i
Left out: Stephen Kelley, Grant Beard, Frederick Ball, Ronald Foster, Paul Oldham, John Roush, Eduardo Acebedo, John Donaghey, Elizabeth Vonne, Anne DelSanto, Tina Donikowski, Brian Shirley, Bernard Colpitts Jr., Reed David and Lanesha Minnix (share of stake is being verified).
Officers and directors, past 12 months. Their share of stake is being verified and is not shown yet; amounts and trading plans are below.
Officers and directors, Oct 2025 to Oct 2026. Each sale is counted once: under a disclosed plan, else to cover taxes, else no plan disclosed.

"% 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.
Yes. Stephen Kelley sold 50K shares ($15.8M) in the past 12 months, all 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: 99% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 0.9% had no disclosed plan. A trading plan schedules sales in advance.
No. Officers and directors reported no purchases in the past 12 months.

Officer and director open-market sales: $34.5M across 113,342 shares. Plan status and stated purpose are separate questions, and a sale can have both.
The lighter segment is sales with no plan disclosed in the filing ($317K), including tax-related sales outside a plan.
Sales with no 10b5-1 plan and no tax reference in the filing. $317K of it is Lanesha Minnix. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Lanesha Minnix, Feb 13, 2026
55,302 shares ($17.3M) 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.
Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for Advanced Energy Industries 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 1,179 Forms 3, 4 and 5 on record for Advanced Energy Industries Inc (SEC CIK 927003), filed from Jul 24, 2003 to Oct 7, 2026; 58 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.
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".
