"% 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.

Common questions

Is the Lattice Semiconductor Corp CEO selling stock?

No. Ford Tamer reported no open-market sales in the past 12 months.

Why are Lattice Semiconductor Corp insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 69% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 31% had no disclosed plan. A trading plan schedules sales in advance.

Are any Lattice Semiconductor Corp insiders buying?

Yes. 1 officer or director reported 4 purchases 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).

What explains the selling$18.9M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $18.9M across 181,813 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

The lighter segment is sales with no plan disclosed in the filing ($5.9M), including tax-related sales outside a plan.

No plan disclosed · $5.9M

Sales with no 10b5-1 plan and no tax reference in the filing. $1.9M of it is James Lederer. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: David Richardson, Feb 25, 2026

Taxes

159,020 shares ($14.9M) were withheld by the company for taxes, which isn't a market sale.

Purchases · 1 buyer (4 trades)

1 officer or director bought shares in this period, in 4 trades(Form 4 code P, leaving out rows the filings describe as reinvested dividends, plan purchases, private deals or moves into the person's own trust). Across all their filings on record there are 7 purchase trades.

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 uncertainty15 officers and directors not confirmed

Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for Lattice Semiconductor Corp 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 methodology1,498 filings on record, 123 filed in the 12-month period, and how we read them

All 1,498 Forms 3, 4 and 5 on record for Lattice Semiconductor Corp (SEC CIK 855658), filed from Aug 5, 2003 to Oct 13, 2026; 123 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".
