Key Points

  • Silvaco CFO Christopher John Zegarelli sold 2,431 shares on April 1, 2026, for $17,284 to cover tax withholding tied to vested restricted stock units.
  • The sale was matchable under Section 16(b) with a December 8, 2025 purchase; Zegarelli will pay Silvaco $8,088.63, the profit from the matched transaction.
  • Silvaco reported Q4 FY2025 EPS of -$0.03 (versus an expected $0.11) and revenue of $18.3 million in line with guidance; Needham reiterated a Buy rating with a $10.00 target.

Silvaco Group (NASDAQ: SVCO) Chief Financial Officer Christopher John Zegarelli executed a sale of 2,431 shares of the company’s common stock on April 1, 2026, according to a Form 4 filing with the Securities and Exchange Commission.

The shares were sold at prices ranging from $7.03 to $7.16 per share, generating total proceeds of $17,284. The filing states the disposition was performed to cover tax-withholding obligations arising from the vesting of restricted stock units.

Silvaco’s filing further notes that the sale was inadvertently matchable under Section 16(b) of the Securities Exchange Act of 1934 to an earlier purchase made on December 8, 2025. As a result of that matching, Zegarelli will pay Silvaco Group $8,088.63, which the filing identifies as the profit realized from the matched transaction.

After the disposition, Zegarelli is reported to directly own 536,976 shares of Silvaco Group common stock.


Market context in the filing places the company’s shares at $7.19 at the time of reporting, near a 52-week high of $7.44 and following a year-to-date gain of 77.53%. An InvestingPro analysis cited in the filing indicates the stock appears overvalued relative to its Fair Value. The filing also references InvestingPro services that provide additional tips and Pro Research Reports covering Silvaco and other U.S. equities.


The insider transaction notice arrives alongside the company’s recently disclosed fourth-quarter fiscal 2025 results. Silvaco reported earnings per share of -$0.03 for the quarter, below the consensus expectation of $0.11, a negative surprise quantified in the filing as 127.27%. Revenue for the quarter was $18.3 million, which the company said was in line with its guidance.

Research coverage noted in the company update includes Needham, which reiterated a Buy rating on Silvaco with a $10.00 price target, citing what Needham characterized as strong overall fourth-quarter results. Segment-level detail disclosed by the company showed quarter-over-quarter growth in the IP and TCAD segments, while the EDA segment declined.

Silvaco also announced an expanded partnership with Advanced Power Electronics Corp. (APEC), a Taiwan-based power device developer. Under the agreement, APEC has committed to using Silvaco’s simulation tools - including Victory Device 2D, Gateway, and SmartSpice - to support development of its silicon carbide power devices.


All figures and descriptions above are drawn from the company’s regulatory filing and its disclosed quarterly results. The Form 4 filing documents the mechanics and accounting of the insider sale, while the company’s earnings release provides the operational and segment details cited.

Risks

  • The company’s Q4 EPS missed analyst expectations significantly, which could weigh on investor sentiment in the semiconductor software and EDA sectors.
  • Share price momentum has driven SVCO near its 52-week high and InvestingPro flags the stock as overvalued relative to Fair Value, introducing valuation risk for market participants.
  • Concentration of segment performance - with EDA declining while IP and TCAD grew - points to uneven demand across Silvaco’s product lines, which could affect near-term revenue mix and margins.
