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.

Sell
950,000 shares
$2,015,570
Significance 6/10

Director Ngai-Pesic sells 950,000 shares (9.2% of holdings) across 3 tranches from $2.00–$2.26; stock now at $6.39.

Ngai-Pesic Katherine S., a Director, executed 3 separate sales totaling 950,000 shares for $2,015,570.00 (blended average $2.12 per share) between June and November 2025, reducing holdings from 10,307,145 to 9,357,145 shares. All three transactions occurred at substantially lower prices than the current market price of $6.39, which represents a 52-week high of $6.45 and reflects a 30-day surge of +81.0% and 90-day gain of +50.4%. The company remains unprofitable with net income of $-5,299,000.00 against quarterly revenue of $18,672,000.00, creating a disconnect between fundamental weakness and recent stock appreciation. The timing of these sales—executed months before the stock's sharp upward move—merits attention as context for evaluating insider positioning relative to company financial performance.

Significance 5/10

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.
