[Form 4] PHILLIPS 66 Insider Trading Activity

Rhea-AI Filing Summary

Phillips 66 (PSX) – Form 4 insider transaction: Director Sigmund L. Cornelius reported buying 500 shares of Phillips 66 common stock on 07/31/2025 at $123.55 per share (transaction code P – open-market purchase). After the acquisition, the director directly owns 21,543 shares, which figure includes 1,043 time-based Restricted Stock Units that will settle 1-for-1 in PSX stock. No derivative security activity was disclosed. The filing was signed by attorney-in-fact William H. Bald on 08/01/2025.

The purchase increases the director’s direct ownership by roughly 2.4% versus the 21,043 shares held previously. While the dollar value (~$62k) is modest relative to Phillips 66’s market capitalization, insider buying can signal alignment with shareholder interests.

Positive

• Director insider purchase: 500 shares acquired at $123.55, indicating personal capital commitment and potential confidence in PSX valuation.

Negative

• Transaction size is small: ~2.4% increase in holding and ~$62k value are immaterial to the company’s overall share volume and may limit market impact.

Insights

Securities Analyst

TL;DR: Director bought 500 PSX shares at $123.55, lifting stake to 21,543; small but directionally positive.

The Form 4 shows a straightforward open-market purchase, not option exercise or automatic grant. Although the 500-share size is minor (≈$62k), insider buying—especially by a non-executive director—often conveys confidence in future performance. The transaction modestly increases direct ownership and adds marginal positive sentiment, but is unlikely to be market-moving given Phillips 66’s large float. No red flags appear; no sales or derivative hedges were reported.
