What stands out

Two officers sold more than 25% of vested holdings: Ann Kluppel (37% of holdings, $1.7M, none under a disclosed plan) and Don Baldridge (58% of holdings, $1.2M, none under a disclosed plan).Ann Kluppel: largest sale, Aug 10, 2026 · Don Baldridge: largest sale, Feb 17, 2026

Three officers sold $48.7M with no disclosed plan: Brian Mandell ($27.8M), Richard Harbison ($11.7M) and Kevin Mitchell ($9.2M). The filings don't state a reason.Brian Mandell: largest such sale, Mar 12, 2026 · Richard Harbison: largest such sale, Aug 12, 2026 · Kevin Mitchell: largest such sale, May 8, 2026

Kevin Meyers bought 350 shares for $61K, first on Mar 17, 2026.Purchase, Mar 17, 2026

Percentages cover 17 of 22 officers and directors. 5 are left out

Left out: Kevin Mitchell, Brian Mandell, Vanessa Sutherland and Richard Harbison (most of their shares vested during the period, so a percentage would mislead); Howard Ungerleider (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 the insider's vested stake at the start of the period (Oct 8, 2025). The gold part is what they sold.

Common questions

Is the Phillips 66 CEO selling stock?

No. Mark Lashier reported no open-market sales in the past 12 months.

Why are Phillips 66 insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 16% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 84% had no disclosed plan. A trading plan schedules sales in advance.

Are any Phillips 66 insiders buying?

Yes. 1 officer or director reported 2 purchases in the past 12 months (Form 4 code P, which includes private purchases).

How much of their stake did Phillips 66 insiders sell?

About 6.2% overall. As a group they ended with more shares than they started with. 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.

22 of 22 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (6 exactly, 16 with a minor or footnoted difference). Percentages cover 17 of 22 officers and directors. Left out: Kevin Mitchell, Brian Mandell, Vanessa Sutherland and Richard Harbison (most of their shares vested during the period, so a percentage would mislead); Howard Ungerleider (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$62.5M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $62.5M across 348,796 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Disclosed plan · $10.0M · 16%

84%

The lighter segment is sales with no plan disclosed in the filing ($52.5M), including tax-related sales outside a plan.

No plan disclosed · $52.5M

Sales with no 10b5-1 plan and no tax reference in the filing. $27.8M of it is Brian Mandell. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Richard Harbison, Aug 12, 2026

Taxes

27,583 shares ($4.4M) were withheld by the company for taxes, which isn't a market sale.

Purchases · 1 buyer (2 trades)

1 officer or director bought shares in this period, in 2 trades(Form 4 code P). Across all their filings on record there are 11 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.

Sources and methodology706 filings from SEC EDGAR, and how we read them

All 706 Forms 3, 4 and 5 filed for Phillips 66 (SEC CIK 1534701) from Apr 12, 2012 to Sep 17, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages. 15 filings were left out because Phillips 66 filed them as an owner of another company's stock.

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".
