[Form 4] Mativ Holdings, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Super Micro Computer, Inc. (SMCI) – Form 4 insider filing

Director Judy L. Lin reported the routine conversion of 1,580 restricted stock units (RSUs) into common shares on 06/30/2025 (transaction code M). The RSUs, originally granted for FY-2025 service, fully vested on the same date and were settled on a one-for-one basis at a $0 exercise price. Following the transaction, Lin’s direct ownership increased to 54,940 SMCI shares. All derivative holdings related to this grant are now exhausted.

The grant and resulting share totals reflect SMCI’s 10-for-1 forward stock split effective 09/30/2024; prior disclosures were restated accordingly. No open-market purchases or sales were reported, indicating the filing documents an automatic equity award settlement rather than an elective trade.

Positive

• Director’s shareholding rises to 54,940 shares, modestly aligning insider interests with shareholders.
• No shares sold; the filing reflects retention rather than liquidation.

Negative

• None.

Insights

Securities Analyst

TL;DR: Routine RSU vesting; neutral impact.

The Form 4 shows a standard vesting and settlement of 1,580 post-split RSUs granted to Director Judy L. Lin. Because the shares were issued at no cost under an existing compensation plan—and represent less than 0.1 % of SMCI’s ~176 mn outstanding shares—the event is immaterial to valuation or float dynamics. No discretionary buying or selling signal is present; therefore, the disclosure is viewed as compliance-driven and neutral for investors.
