TDYTeledyne Technologies · Insider ownership research

Teledyne Technologies insiders sold $11.9M in the past 12 months. How much of their stake is that?

About 6.5% overall. As a group they still hold 96% of their starting shares. The biggest individual seller, Jason VanWees, gave up 14% of starting holdings. These figures leave out Robert Mehrabian, the largest holder (holdings couldn't be fully reconciled).

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

Aug 12, 20262 directors sold 6.9K shares ($4.7M) with no plan disclosed. That is between 2.1% and 10% of each person's 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 a quarter of the 5-year average. 4 insiders sold; the average is 8 a year. Year by year

What stands out

Three insiders sold $11.6M with no disclosed plan: Jason VanWees ($4.7M, 14% of holdings), Simon Lorne ($4.4M, 10%) and Michael Smith ($2.5M, 7.8%). The filings don't state a reason.Jason VanWees: largest such sale, Feb 3, 2026 · Simon Lorne: largest such sale, Aug 12, 2026 · Michael Smith: largest such sale, Jan 29, 2026

Percentages cover 14 of 17 officers and directors. Left out: Robert Mehrabian and Jane Sherburne (holdings couldn't be fully reconciled); Laura Black (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

Common questions

Is the Teledyne Technologies CEO selling stock?

No. George Bobb III reported no open-market sales in the past 12 months.

Why are Teledyne Technologies 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 Teledyne Technologies insiders buying?

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

How much of their stake did Teledyne Technologies insiders sell?

About 6.5% overall. As a group they still hold 96% of their starting shares. The biggest individual seller, Jason VanWees, gave up 14% of starting holdings. These figures leave out Robert Mehrabian, the largest holder (holdings couldn't be fully reconciled). That covers the 12 months to Oct 8, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

15 of 17 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (11 exactly, 4 with a minor or footnoted difference). For 2 we show sales but not holdings; the ! icon on their rows explains why. Percentages cover 14 of 17 officers and directors. Left out: Robert Mehrabian and Jane Sherburne (holdings couldn't be fully reconciled); Laura Black (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$11.9M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $11.9M across 18,417 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

No plan disclosed · $11.9M

Sales with no 10b5-1 plan and no tax reference in the filing. $4.7M of it is Jason VanWees. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Simon Lorne, Aug 12, 2026

Taxes

2,492 shares ($0) 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.

Known gaps and uncertainty2 insiders whose holdings couldn't be fully reconciled

Robert Mehrabian: holdings couldn't be fully reconciled (difference of -14,400 shares). Balance changed without a matching transaction, and the footnote does not state the amount: -14,400 shares on Jan 24, 2026 (Direct). Filing, Jan 24, 2026

Footnote: "Represents shares forfeited upon vesting of the 2023-2025 Restricted Stock Award Program."

Jane Sherburne: holdings couldn't be fully reconciled (difference of -2,000 shares). Balance changed without a matching transaction, and the footnote does not state the amount: -2,000 shares on Apr 22, 2026 (Direct). Filing, Apr 22, 2026

Footnote: "Represents Restricted Stock Units issued to the Reporting Person under the Administrative Rules of the Amended and Restated Teledyne Technologies Incorporated 2014 Incentive Award Plan Related to Non-Employee Director Restricted Stock Unit Awards and Fees. Each Restricted Stock Unit represents a contingent right to receive one share of Teledyne Common Stock. Units vest one year from the date of grant. Shares of common stock will be delivered to the Reporting Person following the vesting date, unless the Reporting Person has made an election to defer delivery of shares until separation from Boa"

Jason VanWees: minor difference of 139 shares. Difference is under 0.5% of holdings.

Melanie Cibik: minor difference of 30 shares. Difference is under 0.5% of holdings.

Stephen Blackwood: minor difference of 3 shares. Difference is under 0.5% of holdings.

George Bobb III: minor difference of 11 shares. Difference is under 0.5% of holdings.

Inferred rename: "Trust" is treated as the same holder as "Securities held in trust", because the old name was never reported again and the new one opened with the same balance (2,034 shares). Old name, new name

Inferred typo: the share class "Common Stoci" is treated as the same class as "Common Stock" on 1 holding line, because the two spellings are nearly identical and each balance carried over exactly. Example (Aldo Pichelli, 34,386 shares): old title, new title

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

Sources and methodology1,467 filings from SEC EDGAR, and how we read them

All 1,467 Forms 3, 4 and 5 filed for Teledyne Technologies (SEC CIK 1094285) from Apr 25, 2003 to Aug 13, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages. 8 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".
