AEIS ADVANCED ENERGY INDUSTRIES INC Insider Trading

CFO Oldham Paul R sold 4,314 shares at $315.99 for $1.4M; stock up 51.7% in 90 days, valuations elevated (P/E 51.70).

Oldham Paul R, EVP and CFO of ADVANCED ENERGY INDUSTRIES INC, executed an open-market sale of 4,314 shares at $315.99, reducing holdings by 16.3% from 26,531 to 22,217 shares. The stock has appreciated sharply: +51.7% over the prior 90 days and +4.4% over 30 days, now trading at $327.80, within 3.7% of its 52-week high of $340.42. His cross-ticker track record shows 1 prior sell with an average 90-day return of +54.7% after the sale (indicating poorly-timed selling in hindsight), and at this ticker specifically, his prior November 2025 sell followed the same pattern (+54.7% 90-day gain). Fundamentals remain strong: $463.3M latest-quarter revenue, $46.2M net income, and 21.4% annual revenue growth, but the P/E ratio of 51.70 reflects elevated valuation multiples. The timing of this sale near the 52-week high, after substantial recent gains, contrasts with the fundamental growth trajectory and his own historical pattern of selling before appreciating periods.

AEIS CEO Stephen Douglas sold 50,000 shares for $15.8M on 2026-03-10 (blended avg $316.62), reducing holdings 38.4%

Stephen Douglas, President and CEO of Advanced Energy Industries, executed 13 separate sales totaling 50,000 shares for $15,830,828.91 on a single date, reducing his holdings from 130,376 to 80,376 shares. The transaction was conducted across a narrow price range ($305.48–$321.13) on the same day, with the stock trading near its 52-week high of $340.42, approximately 10.2% below that peak. The sale represents a material reduction in CEO shareholding (38.4% of pre-transaction holdings) at a time when the company has demonstrated strong fundamental momentum: annual revenue growth of 21.4%, a P/E of 48.24, and recent quarterly net income of $46.2M on $463.3M in revenue.

Director Roush sold 10,225 shares ($3.3M) at $323.56 avg, reducing stake 27%; stock now -14.6% from $340.42 high

Director John A Roush executed 7 separate sales totaling 10,225 shares for $3,308,396.91 on a single day, with transaction prices ranging from $319.78 to $326.75 and a blended average of $323.56. His holdings fell 27.0% to 27,593 shares post-transaction. The sales occurred near the 52-week high of $340.42, though the current price of $290.78 reflects a -14.6% pullback from that peak. AEIS stock has shown strong recent momentum (+14.2% over 30 days, +32.6% over 90 days), yet the director chose to liquidate a substantial portion at elevated valuations. The company's fundamentals remain robust—$463.3M in latest quarterly revenue, $46.2M net income, and +21.4% annual revenue growth—though the P/E of 45.86 reflects a premium valuation. The concentrated sale of a meaningful block merits investor attention to assess whether the liquidation reflects any underlying shift in directional conviction or portfolio management.

CFO Oldham sells 8,174 AEIS shares at $203.11; stock now $196.00; post-sale holdings 24,792 shares

CFO Paul R Oldham sold 8,174 shares at $203.11 on 2025-11-19, reducing his holdings by 24.8% to 24,792 shares, and realizing $1,660,221.14 in proceeds. The stock has declined 13.2% from its 52-week high of $225.80 but remains up 26.8% over the past 90 days and 2.9% over the past 30 days, indicating recent momentum despite the broader pullback. AEIS carries a notably elevated P/E of 88.29 and faces a headwind of -10.5% annual revenue growth, while the company generated $46.2M net income on $463.3M in quarterly revenue. The sale represents a material reduction in his direct ownership stake during a period of volatile valuation and slowing growth.

EVP/COO Bernal sold 19,309 shares (49.3% of holdings) for $2,155,137.23 at blended average $111.61

Acebedo Eduardo Bernal, EVP and COO, executed 2 separate sales on 2025-03-03 totaling 19,309 shares for $2,155,137.23, reducing his stake from 39,131 shares to 19,822 shares—a 49.3% reduction in holdings. The transaction occurred at a blended average price of $111.61, slightly above the current market price of $110.60, though the stock remains 15.9% below its 52-week high of $131.54. This sale is notable given the company's recent operational headwinds: Advanced Energy reported a net loss of $14,905,000 in the latest quarter and annual revenue declined 10.5% year-over-year, creating a structural backdrop of weakness. The magnitude of this reduction—divesting half his position—paired with deteriorating fundamentals warrants investor attention to whether additional management changes or strategic announcements may follow.
