Robert W Duggan (Co-CEO) buys 100,000 shares of SMMT at $14.60; stock now -52.1% from 52-week high, cluster buy pattern detected.

Co-Chief Executive Officer Robert W Duggan purchased 100,000 shares at $14.60 on 2026-06-04, increasing holdings to 25.82M shares. The transaction occurred as the stock trades 52.1% below its 52-week high of $30.98 and has fallen 15.4% over the prior 30 days. At this same ticker, Duggan's 3 prior buys have shown poor timing at the 90-day mark: 0 of 3 prior purchases were well-timed, with results ranging from -12.2% to +20.8% at 30 days but consistently negative at 90 days. Two other insiders also purchased shares within the past 14 days, indicating a cluster-buy pattern. The company remains unprofitable with net income of $-189.4M over the most recent full fiscal year, though Duggan's cross-ticker track record shows an average 90-day return of +3.9% across 20 prior buys, with a 40.00% win rate.

Co-CEO Mahkam Zanganeh buys 100,000 SMMT shares at $14.60; stock down 52.1% from 52-week high despite $1.5M buy.

Mahkam Zanganeh, Co-Chief Executive Officer, purchased 100,000 shares at $14.60 on 2026-06-04, increasing his holdings from 25,724,474 to 25,824,474 shares. The stock has declined 52.1% from its 52-week high of $30.98 and is trading at $14.84, down 15.4% over the past 30 days. At the same ticker, his prior 5 buys show mixed outcomes: two trades showed 90-day gains of +115.9% and +115.3%, while the most recent buy on 2025-10-21 yielded a 90-day return of -9.1%. The company is unprofitable with a net income of $-189,424,000.00 for its most recent fiscal year and zero revenue in the latest quarter, presenting a high-risk fundamental backdrop against which this equity purchase occurs.

COO and CFO Manmeet Singh Soni bought 50,000 shares at blended average price $14.44 on 2026-06-04, adding to 3.12M share position. Stock down 52.1% from 52-week high.

Manmeet Singh Soni, serving as both COO and CFO, executed 2 separate purchases totaling 50,000 shares for $722,250.00 at average price $14.44 on 2026-06-04. The purchase increases his holdings to 3,123,603 shares. This purchase occurs as the stock trades at $14.84, down 52.1% from its 52-week high of $30.98 and down 15.4% over the prior 30 days. Soni's cross-ticker track record shows 1 prior buy against 9 prior sells, and his single prior buy at SMMT (2023-10-13) has no measurable outcome data. The company posted negative net income of $-189,424,000.00 and zero revenue in the latest quarter, indicating material operational challenges. The timing of this insider purchase against depressed valuation and company fundamentals warrants attention, though the insider's historical bias toward selling activity limits inference of strong conviction from a single buy transaction.
