CFO John W Jr Kosiba sells 36,909 shares for $1,862,034.19 under pre-arranged 10b5-1 plan at AMSC

John W Jr Kosiba, SVP, CFO & Treasurer, executed 7 separate sales totaling 36,909 shares for $1,862,034.19 across June 2–3, 2026, at prices ranging from $48.31 to $52.19 (blended average $50.45). This sale reduces his holdings from 382,890 shares to 345,981 shares, a -9.6% reduction. The transaction is part of a pre-arranged 10b5-1 trading plan, meaning it was scheduled and not discretionary. The company's latest quarter shows revenue of $74,529,000.00, net income of $117,806,000.00, annual revenue growth of +34.3%, and a P/E of 8.63, reflecting solid fundamentals. The current stock price of $46.67 is -33.8% from the 52-week high of $70.49, indicating the stock has retreated significantly from its peak despite the company's strong earnings trajectory.

Significance 7/10

SVP/CFO Kosiba sells full position: 59,843 shares for $3.27M across 3 transactions at AMSC; stock near 52-week highs.

John W. Kosiba Jr., SVP, CFO & Treasurer, executed 3 separate sales totaling 59,843 shares for $3,273,380.45 on 2025-08-04, liquidating his entire AMSC holdings at a blended average price of $54.70. The timing coincides with the stock trading 3.5% below its 52-week high of $56.85 and on the heels of a 36.3% 30-day rally and 156.5% 90-day surge, suggesting the CFO elected to divest after substantial recent appreciation. His prior trades at AMSC show 2 of 2 measurable 90-day outcomes were well-timed at the 90-day mark, and his cross-ticker track record reflects a 100% well-timed rate on 4 prior sells. This complete exit by a senior financial officer—eliminating exposure entirely rather than reducing a position—warrants attention alongside the company's elevated valuation (P/E 161.38) and recent steep revenue growth (+53.0% annually).

Significance 6/10

CFO Kosiba sells 50,000 AMSC shares (10.8% of holdings) for $1.3M; 2 prior AMSC sales both well-timed at 90-day mark

John W Kosiba Jr, SVP, CFO & Treasurer, executed 2 separate sales totaling 50,000 shares for $1,319,756.80 at a blended average price of $26.40. His post-transaction holdings stand at 414,276 shares (414.3K shares), down from 464,276 shares (464.3K shares) pre-transaction, representing a 10.8% reduction. His prior sales at AMSC show a consistent pattern: a 2024-11-04 sale generated 30d +24.6% and 90d -7.1% returns, while a 2024-06-11 sale produced 30d +34.1% and 90d -8.0% returns; both prior sales were well-timed at the 90-day mark. Current market price of $28.04 is 23.8% below the 52-week high of $36.81, though the stock is up 38.7% over the past 30 days and 23.5% over 90 days.

Sell
50,000 shares
$1,414,095
Significance 6/10

CFO John W Kosiba Jr sells 50,000 AMSC shares at $28.28; stock up 21.8% in 30 days but company unprofitable in FY.

Kosiba sold 50,000 shares (356.1K remaining) on 2024-11-04 at $28.28 after the stock had risen 40.8% over 90 days and 21.8% over 30 days—near its 52-week high of $32.42. His prior sale at AMSC on 2024-06-11 produced a negative 90-day return of -8.0%, making that sale well-timed; this current transaction occurs at a more elevated price point in the stock's recovery. Fundamentally, the company reported annual revenue growth of +37.4% and latest quarter net income of $4.9M, yet remains unprofitable on a full-year basis, creating tension between operational momentum and profitability. The timing of this sale—following a sharp 40.8% quarterly rally—alongside the company's FY unprofitability warrant scrutiny into whether the CFO is signaling caution on valuation after a runup, or simply executing a planned adjustment.
