SVCO Form 4: 2,510 shares withheld for taxes; 51,369 shares remain

Rhea-AI Filing Summary

Candace Jackson, SVP, General Counsel and Corporate Secretary of Silvaco Group, Inc. (SVCO), reported a routine share disposition on 10/01/2025 to satisfy tax withholding tied to the vesting of restricted stock units. The filing shows 2,510 shares of common stock were withheld at a price of $5.44, leaving her with 51,369 shares beneficially owned after the transaction. The transaction is coded F, which the filer explains represents shares withheld by the issuer to cover tax obligations arising from RSU vesting. This is an administrative, non-sales transfer rather than an open-market sale and does not indicate an active cash divestiture by the reporting person.

Positive

• Insider retains significant stake: 51,369 shares remain beneficially owned after withholding
• Transaction is routine: disposition coded F and explained as tax withholding on vested RSUs

Negative

• None.

Insights

Corporate Governance Analyst

Routine tax-withholding reduced insider holdings; no active sale signaled.

The report documents a withholding of 2,510 shares at $5.44 on 10/01/2025 to satisfy tax obligations from vested restricted stock units. The filer retained 51,369 shares after the withholding, and the transaction code F matches the stated explanation.

This action is an administrative adjustment tied to compensation vesting rather than a discretionary market sale, so immediate governance or liquidity concerns are limited. Monitor any future Form 4 entries for open-market sales or changes in holding patterns over the next 3–6 months.
