TPLTexas Pacific Land Corporation · Insider ownership research

Texas Pacific Land Corporation insiders sold $2.9M in the past 12 months. How much of their stake is that?

About 0.1% overall. As a group they ended with more shares than they started with. The biggest individual seller, Chris Steddum, sold shares equal to 38% of starting holdings, but more vested, so the stake grew. These figures leave out Murray Stahl, the largest holder (holdings couldn't be fully reconciled).

What stands out

Three directors bought shares: Donna Epps (895 shares, $457K), Murray Stahl (348 shares, $126K) and Peter Doyle (9 shares, $3K).Donna Epps: purchase, Feb 25, 2026 · Murray Stahl: purchase, Sep 29, 2026 · Peter Doyle: purchase, Sep 15, 2026
Donna Epps sold 895 shares (38% of starting holdings), but 1.4K more shares were added, so the stake grew (from 2.4K to 2.9K).Largest sale, Feb 25, 2026
Chris Steddum sold 38% of vested holdings: 4K shares for $1.6M, all under a disclosed plan.Largest sale, Jun 5, 2026

Percentages cover 12 of 14 officers and directors. Left out: Murray Stahl (holdings couldn't be fully reconciled); Stephanie Buffington (most of their shares vested during the period, so a percentage would mislead). 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.

Murray Stahl 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 Texas Pacific Land Corporation CEO selling stock?

No. Tyler Glover reported no open-market sales in the past 12 months.

Why are Texas Pacific Land Corporation insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 56% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 44% had no disclosed plan. A trading plan schedules sales in advance.

Are any Texas Pacific Land Corporation insiders buying?

Yes. 3 officers or directors reported 244 purchases in the past 12 months (Form 4 code P, which includes private purchases).

How much of their stake did Texas Pacific Land Corporation insiders sell?

About 0.1% overall. As a group they ended with more shares than they started with. The biggest individual seller, Chris Steddum, sold shares equal to 38% of starting holdings, but more vested, so the stake grew. These figures leave out Murray Stahl, the largest holder (holdings couldn't be fully reconciled). 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.

13 of 14 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (12 exactly, 1 with a minor or footnoted difference). For 1 we show sales but not holdings; the ! icon on that row explains why. Percentages cover 12 of 14 officers and directors. Left out: Murray Stahl (holdings couldn't be fully reconciled); Stephanie Buffington (most of their shares vested during the period, so a percentage would mislead). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$2.9M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $2.9M across 6,503 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 ($1.3M), including tax-related sales outside a plan.

No plan disclosed · $1.3M

Sales with no 10b5-1 plan and no tax reference in the filing. $809K of it is Stephanie Buffington. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Stephanie Buffington, Feb 24, 2026

Taxes

17,770 shares ($7.3M) were withheld by the company for taxes, which isn't a market sale.

Purchases · 3 buyers (244 trades)

3 officers and directors bought shares in this period, in 244 trades(Form 4 code P). Across all their filings on record there are 4,875 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 uncertainty1 insider whose holdings couldn't be fully reconciled

Murray Stahl: holdings couldn't be fully reconciled (difference of -124,321 shares). Balance changed without a matching transaction, and the footnote does not state the amount: -3,463,017 shares on Jan 5, 2026 (Direct). Filing, Jan 5, 2026

Footnote: "Increase constitutes stock portion of annual retainer for the year of board service by Murray Stahl commencing January 1, 2026 in the amount of 554 shares, and the resulting total reflects a three-for-one stock split effective December 22, 2025."

Peter Doyle: minor difference of -207 shares. Difference is stated in footnotes (unreported vesting, exempt acquisition or transfer).

Inferred rename: "HK Hard Assets LLC" is treated as the same holder as "Horizon Kinetics Hard Assets, LLC", because the old name was never reported again and the new one opened with the same balance (898,425 shares). Old name, new name

Inferred rename: "Bermuda Liquidators II LLC" is treated as the same holder as "Horizon Kinetics Hard Assets II LLC", because the old name was never reported again and the new one opened with the same balance (12,996 shares). Old name, new name

Sources and methodology1,500 filings from SEC EDGAR, and how we read them

All 1,500 Forms 3, 4 and 5 filed for Texas Pacific Land Corporation (SEC CIK 1811074) from Jan 11, 2021 to Oct 1, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages.

Probable 3-for-1 stock split on or before Mar 27, 2024 (split date stated in a footnote). Splits aren't reported as transactions; 23 holding lines changed by exactly this ratio, so earlier share counts are restated.

Probable 3-for-1 stock split on or before Dec 22, 2025 (first filing that shows post-split balances). Splits aren't reported as transactions; 14 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".
