Recent activity

Past 30 days, Sep 14, 2026 to Oct 13, 2026

Sep 15, 2026Geoffrey Moore sold 4.5K shares ($171K) under a disclosed trading plan.

Who	Shares	Price	% of total stake	Total stake after	Trade date	Filed
Geoffrey Moore Director	4,452	$38.45	n/a	n/a	Sep 15, 2026	Sep 17, 2026

"% 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

Douglas Carlisle 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.

Common questions

Is the Nlight, Inc. CEO selling stock?

Yes. Scott Keeney sold 1.05M shares ($56.2M) in the past 12 months, 88% of it under a trading plan disclosed in the filings.

Why are Nlight, Inc. insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 85% of sales by value ran under 10b5-1 trading plans disclosed in the filings, 14% were to cover taxes and 0.7% had no disclosed plan. A trading plan schedules sales in advance.

Are any Nlight, Inc. insiders buying?

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

What explains the selling$71.6M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $71.6M across 1,321,150 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Disclosed plan · $60.9M · 85%

15%

The lighter segment is sales with no plan disclosed in the filing ($10.7M), including tax-related sales outside a plan.

No plan disclosed · $480K

Sales with no 10b5-1 plan and no tax reference in the filing. $444K of it is Raymond Link. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Raymond Link, Nov 11, 2025

Taxes

$19.3M of sales (26.9%) cite tax obligations in their footnotes, $9.0M of them also under a plan. Example: James Nias, Sep 3, 2026

Charitable gifts · 8.5K 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 uncertainty12 officers and directors not confirmed

Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for Nlight, 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 methodology416 filings on record, 50 filed in the 12-month period, and how we read them

All 416 Forms 3, 4 and 5 on record for Nlight, Inc. (SEC CIK 1124796), filed from Apr 25, 2018 to Sep 17, 2026; 50 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.

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".
