RHINES WALDEN C 4

What Happened
Walden C. Rhines, CEO of Silvaco Group, Inc. (SVCO), received a grant of 28,170 Restricted Stock Units (RSUs) on February 21, 2026. The RSUs were granted at a $0.00 per-share price (award/grant), so no cash was exchanged; the filing reports $0 total consideration. The RSUs will vest on March 31, 2027, subject to the acceleration terms described below.

Key Details

• Transaction date: February 21, 2026; Form 4 filed March 2, 2026 (appears to be filed 9 days after the transaction, later than the standard 2-business-day requirement).
• Security/amount: 28,170 RSUs granted; reported acquisition code A (award/grant); price reported $0.00.
• Shares owned after transaction: Not disclosed in the filing.
• Footnote: RSUs granted pursuant to an Employment Agreement effective August 19, 2025. Each RSU is a contingent right to one common share and vests on March 31, 2027. Vesting will be accelerated if the company terminates the CEO’s employment for any reason, or if the CEO terminates following a material, uncured breach by the company (provided the breach is not cured within 30 days after written notice), if either occurs before March 31, 2027.

Context
RSU grants are common executive compensation and do not reflect an immediate purchase or sale of shares; they convert to actual stock only if/when they vest. The $0.00 price simply indicates an award rather than a market transaction. The late filing reduces the timeliness of public disclosure for investors; the filing does not state whether any tax-withholding or share-forfeiture provisions apply.
