Bruce Claflin (4.7% of holdings) sold $1.0M of stock with no disclosed trading plan. The filings don't state a reason.Largest such sale, Sep 24, 2026
Percentages cover 17 of 18 officers and directors. Left out: Grant Hoffman (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 Ciena CEO selling stock?
Yes. Gary Smith sold 168K shares ($46.5M, 59% of starting holdings) in the past 12 months, all of it under a trading plan disclosed in the filings.
Why are Ciena insiders selling?
Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 96% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 4% had no disclosed plan. A trading plan schedules sales in advance.
Are any Ciena insiders buying?
No. Officers and directors reported no purchases in the past 12 months.
How much of their stake did Ciena insiders sell?
About 20% overall. As a group they still hold 92% of their starting shares. The biggest individual seller, Gary Smith, gave up 59% of starting holdings. 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.

18 of 18 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (18 exactly, 0 with a minor or footnoted difference). Percentages cover 17 of 18 officers and directors. Left out: Grant Hoffman (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$99.4M of sales by plan status, purpose, seller and month
Officer and director open-market sales: $99.4M across 329,263 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 ($4.3M), including tax-related sales outside a plan.
No plan disclosed · $4.3M
Sales with no 10b5-1 plan and no tax reference in the filing. $3.3M of it is Thomas Nevens. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Thomas Nevens, Dec 15, 2025
Taxes
244,282 shares ($68.4M) 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.

Sources and methodology2,763 filings from SEC EDGAR, and how we read them
All 2,763 Forms 3, 4 and 5 filed for Ciena (SEC CIK 936395) from Jun 10, 1997 to Oct 6, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages. 1 filing was left out because Ciena filed them as an owner of another company's stock. 95 older filings exist only on paper and could not be read.
Probable 1-for-7 stock split on or before Oct 28, 2006 (first filing that shows post-split balances). Splits aren't reported as transactions; 13 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".
