Significance 5/10

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.

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.
