SVCO Silvaco Group, Inc. Insider Trading

Director Katherine S. Ngai-Pesic sold 200,000 shares of SVCO at $11.27 for $2,254,320.00; stock currently $11.47

Director Katherine S. Ngai-Pesic sold 200,000 shares, reducing holdings from 9,376,403 to 9,176,403 shares. The sale price of $11.27 is below the current price of $11.47 and significantly below the 52-week high of $14.14. Her prior three sells at SVCO posted 90-day returns of +66.6%, +81.1%, and +160.0%, yet none achieved well-timed (negative post-sale) outcomes. At the company level, trailing revenue is $17,755,000 with net income of $-5,860,000, indicating the business is unprofitable despite 5.7% annual revenue growth. The sale occurs within a range of recent activity but against fundamentals that continue to show operating losses.

SVCO director Ngai buys 1,000 shares at $13.07; stock now $11.49; prior 5 buys at this ticker showed 0% 90-day win rate.

Ngai Anthony K.K., a director at Silvaco Group (SVCO), purchased 1,000 shares at $13.07 on 2026-06-05, increasing his holdings from 114.0K to 115.0K shares. The stock has declined to a current price of $11.49, placing the transaction 18.7% below the 52-week high. Most notably, Ngai's prior 5 purchases at SVCO all showed negative 90-day returns ranging from -13.3% to -24.3%, with a 0% win rate at the 90-day mark. This pattern of poor timing on same-ticker buys is compounded by the company's fundamental weakness: the latest quarter showed $-5.9M net income despite $17.8M revenue, and the company was unprofitable over its most recent full fiscal year. The cumulative pattern—repeated unprofitable purchases followed by declines, coupled with operating losses—warrants attention to whether the director's continued accumulation reflects information asymmetry or simply reflects an uninformed hold.

Director Ngai Anthony K.K. bought 1,000 shares of SVCO at $4.23; stock now $4.09, down 58.3% from 52-week high.

Ngai Anthony K.K. purchased 1,000 shares on 2025-12-11 at $4.23, expanding his holdings to 91,777 shares. The stock has since declined to $4.09 and is trading 58.3% below its 52-week high of $9.80, reflecting sustained weakness. His prior trades at SVCO show a pattern of unfavorable 90-day outcomes: four completed buys averaged -23.1% over 90 days (ranging from -18.5% to -24.3%), with zero of four prior buys well-timed. Concurrently, the company remains unprofitable (net income $-5.3M in the latest quarter), though annual revenue has grown 10.0%. The clustering of three other insider buys within the past 14 days indicates broader management engagement, but timing patterns suggest caution—prior purchases have consistently resulted in losses over the 90-day window.

Director Katherine S. Ngai-Pesic buys 25,000 shares at $4.13; stock down -57.1% from 52-week high amid cluster activity.

Director Katherine S. Ngai-Pesic purchased 25,000 shares at $4.13 on 2025-12-10, increasing her holdings to 10,300,886 shares (10.30M shares). The purchase occurs within a backdrop of significant stock deterioration: SVCO is trading at $4.20 current price, down -57.1% from its 52-week high of $9.80 and down -16.7% over the past 30 days. The company's fundamentals present a mixed picture—revenue is $18,672,000.00 ($18.7M) in the latest quarter with annual revenue growth of +10.0%, but the company recorded net income of $-5,299,000.00 ($-5.3M) and remains unprofitable on a full-year basis. This insider buy is part of a cluster pattern, with 2 other insiders also purchasing within the past 14 days. At the same ticker, Ngai-Pesic's prior 3 trades (all sells) show mixed outcomes: her June 2025 sale demonstrated good timing with a +160.0% 90-day return (stock rose after she exited), but her more recent November 2025 sale's outcome remains unmeasurable. The purchase at a steep discount from recent highs, combined with the cluster activity, merits investor attention to understand the rationale for accumulation at depressed valuations.

CEO Walden C Rhines purchased 13,100 shares of SVCO at $4.01; stock down 58.8% from 52-week high, company unprofitable.

Walden C Rhines, the CEO, acquired 13,100 shares for $52,500.87 on 2025-12-09, expanding his holdings by 14.1% to 105,918 shares. The transaction occurred while Silvaco trades at $4.04, down 58.8% from its 52-week high of $9.80, and the stock has declined 18.6% over the prior 30 days. However, the same-ticker history shows two prior buys on 2025-11-18 and 2025-11-17 with outcomes not yet measurable, and the TIMING PATTERN shows 0 of 0 prior buys were well-timed at the 90-day mark. Fundamentally, the company reported net income of $-5,299,000.00 for the latest quarter and was unprofitable over its most recent full fiscal year, despite annual revenue growth of 10.0%. The CEO's accumulation amid sustained unprofitability and depressed valuation is noteworthy but requires monitoring of whether this pattern of recent rapid purchases reflects confidence or responds to near-term operational pressures.

CFO Zegarelli buys 10,000 SVCO shares at $3.80; stock down 22.8% in 30 days, -60.9% from 52-week high.

Zegarelli Christopher John, CFO of Silvaco Group, purchased 10,000 shares at $3.80 on 2025-12-08, bringing his holdings to 439,407 shares. The purchase occurs during significant weakness: the stock has declined 22.8% over the past 30 days and trades 60.9% below its 52-week high of $9.80. Notably, this is his third buy at SVCO within two months (prior buys on 2025-11-17 and 2025-09-15), while the company faces operational headwinds—the most recent quarter showed net income of $-5,299,000.00 on revenue of $18,672,000.00, and the company was unprofitable over its most recent full fiscal year. His cross-ticker track record shows 2 prior buys with an average 30-day return of +18.3%, though at SVCO specifically his 2025-09-15 buy achieved a +18.3% 30-day return while the outcome of his more recent November purchase remains incomplete.

Director Ngai Anthony K.K. buys 10,000 SVCO shares at $4.26; stock down 26.7% in 30 days, now trading -55.1% from 52-week high.

Ngai Anthony K.K. acquired 10,000 shares of Silvaco (SVCO) at $4.26 on 2025-11-18, bringing his holdings to 90,777 shares (+12.4% increase). The purchase occurs while SVCO has declined 26.7% over the past 30 days and trades 55.1% below its 52-week high of $9.80. The company is currently unprofitable with a net loss of $5,299,000 in the latest quarter despite annual revenue growth of 10.0%. Notably, a cluster pattern is present with 2 other insiders also purchasing within the past 14 days, and Ngai's prior five purchases at SVCO all generated positive 30-day returns (+8.8% to +17.7%), though the timing of those earlier buys at this ticker does not yet have measurable 90-day outcomes.

CEO Rhines bought 29,000 SVCO shares at $4.07 (11/18), raising holdings 45.4%; cluster buy pattern observed.

RHINES WALDEN C, Chief Executive Officer of Silvaco Group, Inc., purchased 29,000 shares at $4.07 on 2025-11-18, adding $118,166.30 in value and increasing his holdings by 45.4% to 92,818 shares post-transaction. The timing reflects a 56.6% discount from the 52-week high of $9.80, and occurs alongside a broader cluster pattern: 2 other insiders also bought within the past 14 days. Silvaco is currently unprofitable (net income $-5.3M in the latest quarter) despite 10.0% annual revenue growth, placing this purchase within a company facing earnings pressure. The CEO's substantial stake increase, combined with the multi-insider cluster buy pattern, adds material signal to investor scrutiny despite the stock's recent 27.6% 30-day decline from elevated levels.

SVCO CEO bought 11,272 shares at $3.90; holds 63,818 shares post-transaction; stock down 59.1% from 52-week high.

CEO Walden C Rhines purchased 11,272 shares at $3.90 on 2025-11-17, increasing his holdings to 63,818 shares (+21.5% vs pre-transaction holdings). The purchase occurs against a backdrop of significant stock weakness: the current price of $4.01 is down 59.1% from the 52-week high of $9.80, and the stock has declined 28.0% over the prior 30 days. Silvaco remains unprofitable with net income of $-5,299,000.00 in the latest quarter, despite annual revenue growth of 10.0% to $18,672,000.00. A cluster pattern is also present: 2 other insiders bought within the same 14-day window. This concurrent buying by multiple insiders, at a depressed valuation relative to recent trading ranges, is noteworthy given the company's losses, though the timing signal is neutral—the insider's prior buy at this ticker (1 prior trade) has outcomes not yet measurable.

CFO Zegarelli buys 5,000 (5.0K shares) SVCO at $3.91; cluster of 2 other insider purchases within 14 days amid -28.0% 30-day decline.

Christopher John Zegarelli, Chief Financial Officer, purchased 5,000 (5.0K shares) at $3.91 on 2025-11-17, increasing holdings by +1.2% to 429,407 shares (429.4K shares). The transaction coincides with a cluster pattern: 2 other insiders also bought within the past 14 days. However, context is complex: the stock is trading at $4.01 against a 52-week high of $9.80 (-59.1%), has declined -28.0% in 30 days and -9.7% in 90 days, and the company is unprofitable with net income of $-5,299,000.00 ($-5.3M) over its most recent full fiscal year despite +10.0% annual revenue growth. Zegarelli's cross-ticker track record shows 1 prior buy with a +18.3% 30-day return, and his prior SVCO purchase on 2025-09-15 posted +18.3% over 30 days (90-day outcome not yet measurable). The cluster buying pattern alongside significant recent price deterioration merits scrutiny into whether insiders are accumulating at depressed levels or responding to strategic developments not yet public.
