LIILennox International · Insider ownership research

Lennox International insiders sold $1.4M in the past 12 months. How much of their stake is that?

About 2.3% overall. As a group they ended with more shares than they started with. The biggest individual seller, Todd Teske, gave up 16% of starting holdings. These figures leave out John Norris III, the largest holder (most holdings were last confirmed in 2019).

No officer or director trades were reported for the past 30 days. The most recent before that:

Aug 6, 2026John Norris III gave away 9K shares as a gift. That is 0.3% of the total stake held that day.

"% of total stake" is the shares in this 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 don't reconcile, 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.

Is this normal? Less than usual: about one-twentieth of the 5-year average. 3 insiders sold; the average is 9 a year. Year by year

What stands out

Shane Wall sold 100 shares (4.3% of starting holdings), but 343 more vested, so the stake grew (from 2.3K to 2.5K).Largest sale, Feb 25, 2026
Tax withholding outweighed market sales: the company withheld $8.0M of officers' and directors' shares for taxes, against $1.4M sold on the open market. The largest was Alok Maskara ($4.8M withheld).Largest withholding, Mar 13, 2026

Percentages cover 14 of 16 officers and directors. Left out: John Norris III (most holdings were last confirmed in 2019); Tracy Embree (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 Lennox International CEO selling stock?

No. Alok Maskara reported no open-market sales in the past 12 months.

Why are Lennox International insiders selling?

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.

Are any Lennox International insiders buying?

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

How much of their stake did Lennox International insiders sell?

About 2.3% overall. As a group they ended with more shares than they started with. The biggest individual seller, Todd Teske, gave up 16% of starting holdings. These figures leave out John Norris III, the largest holder (most holdings were last confirmed in 2019). 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.

16 of 16 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (16 exactly, 0 with a minor or footnoted difference). Percentages cover 14 of 16 officers and directors. Left out: John Norris III (most holdings were last confirmed in 2019); Tracy Embree (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$1.4M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $1.4M across 2,625 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

No plan disclosed · $1.4M

Sales with no 10b5-1 plan and no tax reference in the filing. $669K of it is Todd Teske. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Chris Kosel, May 6, 2026

Taxes

16,468 shares ($8.0M) were withheld by the company for taxes, which isn't a market sale.

Charitable gifts · 9K 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.

External context: we only cite outside events when a documented connection exists. None is shown for this period.

Sources and methodology2,705 filings from SEC EDGAR, and how we read them

All 2,705 Forms 3, 4 and 5 filed for Lennox International (SEC CIK 1069202) from Sep 8, 2000 to Aug 10, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages. 336 older filings exist only on paper and could not be read.

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".
