[Form 4] POST HOLDINGS, INC. Insider Trading Activity

Rhea-AI Filing Summary

Form 4 – Kinder Morgan, Inc. (KMI) discloses that Vice President & General Counsel Catherine C. James settled 51,994 restricted stock units (RSUs) into Class P common shares on 31 Jul 2025 (code M). To satisfy tax-withholding requirements, the issuer retained 19,951 shares at the $28.06 closing price (code F), leaving a net 32,043-share increase in the insider’s direct ownership at zero cash cost.

Post-transaction, James directly owns 142,604 shares and indirectly holds 361 shares (75 via spouse, 286 via 401(k)). All reported RSUs are now fully vested; no derivative securities remain outstanding.

The filing reflects routine equity-compensation settlement rather than discretionary buying or selling, carrying neutral market implications but signalling continued executive equity alignment.

Insights

Senior Securities Analyst

TL;DR: Routine RSU vesting; insider’s stake grows 23% with no open-market trade—neutral signal.

The settlement of 51.9k RSUs and withholding of 19.9k shares is standard tax administration. Because the insider neither bought nor sold shares on the market, the transaction offers little insight into management’s valuation view. Direct ownership rises to 142.6k shares, enhancing alignment, yet the incremental 32k shares represent <1% of daily KMI volume and are immaterial to float. I classify the filing as not impactful for valuation or trading sentiment.

Corporate Governance Specialist

TL;DR: Compensation-driven transfer, governance posture unchanged.

RSU settlements are built into Kinder Morgan’s executive pay structure. The absence of a 10b5-1 plan box and the mechanical nature of the disposition indicate no intent to time the market. Share withholding for taxes avoids cash outlay and prevents open-market selling pressure. From a governance standpoint, continued equity accumulation by the GC supports shareholder-management alignment, but the event does not materially alter control or incentive architecture.
