[Form 4] T-Mobile US, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Sezzle Inc. (SEZL) – Form 4 insider transaction

Executive Chairman & CEO Charles G. Youakim, who is also a Director and 10 % owner, reported the disposition of 6,978 shares of Sezzle common stock on 01 Jul 2025. The transaction is coded “F,” indicating shares were automatically withheld by the company to cover taxes arising from the vesting of previously granted restricted stock units (RSUs). The shares were valued at $167.58 each, implying an aggregate value of roughly $1.17 million.

Following the withholding, Youakim continues to own 12,346,449 shares directly and an additional 2,455,824 shares indirectly through Cerro Gordo LLC (947,370) and the Charles G. Youakim 2020 Irrevocable GST Trust (1,508,454). His total beneficial stake therefore remains about 14.8 million shares, underscoring a substantial continuing alignment with shareholders.

No derivative security transactions were reported, and the filing contains no information on company fundamentals or outlook. The reported sale represents only 0.05 % of Mr. Youakim’s post-transaction holdings and appears routine rather than a signal of changed sentiment.

Insights

Securities Analyst

TL;DR: Routine tax-withholding sale of 6,978 SEZL shares; negligible versus 14.8 m stake. Neutral for valuation; confirms large insider ownership.

The “F” code flags an automatic share forfeiture to satisfy withholding taxes on vested RSUs, not an open-market sale. The dollar value (~$1.17 m) is modest relative to Youakim’s remaining 14.8 m-share stake and does not materially alter insider alignment. No derivatives or additional sales were disclosed, implying the action is administrative. From a valuation standpoint, this event is non-impactful; investors should view it as housekeeping rather than an indicator of sentiment.

Corporate Governance Specialist

TL;DR: Filing shows compliance with Section 16, minimal share reduction, insider still holds >10 %—governance stance unchanged.

The Form 4 demonstrates timely disclosure and adherence to Section 16(a) obligations. While any insider disposition can raise questions, the small size (0.05 % of total holdings) and tax-related nature mitigate governance concerns. The executive retains a significant ownership position, preserving incentive alignment. Nothing in the filing signals governance risk or information asymmetry. Overall governance impact is neutral.
