Shares of ON Semiconductor jumped 4.47% to €108.40 on the Vienna exchange, as a wave of bullish analyst calls and renewed enthusiasm for chipmakers tied to artificial intelligence and electric vehicles pulled the stock sharply higher. The move raises a pointed question: is the market pricing in a growth story that the company's financials have yet to fully deliver? ON Semiconductor Surges on Analyst Optimism, but Can AI and Auto Chip Demand Justify the Rally?
Shares of ON Semiconductor climbed 4.47% to €108.40 on the Vienna exchange as bullish Wall Street calls and a broad rotation into AI- and auto-exposed chipmakers fueled the latest leg higher. The stock has now surged roughly 143% over the past year, forcing investors to ask whether the recovery story is already priced in — or just getting started.
• Analysts Are Making Aggressive Bets the Worst Is Over
B. Riley analyst Craig Ellis upgraded the stock to Buy from Neutral in April, nearly doubling his price target to $115 from $64.
His thesis: the cyclical trough — the low point in the chip industry's boom-and-bust cycle — is behind the company, and automotive and industrial markets will reaccelerate while gross margins recover from a 38% floor.
Across the Street, 14 analysts now rate the stock a Buy, with none recommending a sell. That unanimity is notable but also raises the risk that any stumble punishes the stock disproportionately.
• The Q1 Beat Was Real, but Modest
In its most recent quarter, onsemi reported revenue of $1.51 billion, topping its own guidance midpoint, with non-GAAP earnings of $0.64 per share — and CEO Hassane El-Khoury declared the company had "moved beyond the cyclical trough," highlighting that its AI data center business "accelerated, growing more than 30% sequentially."
Gross margin reached 38.5%, with free cash flow of $217 million. Solid, but the beat over consensus was only a few pennies — hardly the blowout the stock's trajectory implies.
• AI Data Centers Are the New Growth Engine
Management expects AI data center revenue to double year-over-year in 2026 , powered by demand for high-voltage power chips that feed energy-hungry AI processors. Its gallium nitride chip design pipeline now exceeds $1.5 billion, though meaningful revenue won't arrive until 2027.
Consensus projects full-year 2026 revenue of $6.29 billion and EPS of $2.92 — meaning the stock, near $133 in New York, trades at roughly 45 times this year's earnings. That's a rich price for a company still recovering.
• Insider Selling and Geopolitical Risk Cloud the Picture
Barclays flagged heavy automotive and China exposure when it initiated coverage at a hold-equivalent rating , and insider selling — including by the CFO in April — adds a cautionary signal.
In the past six months, insiders have made 14 open-market trades, all of them sales. When the people running the company are consistently cashing out, the bullish narrative deserves extra scrutiny.
