Shares of Power Integrations surged 8% to $63.72 after the chipmaker delivered a Q2 earnings surprise and paired it with a technology announcement aimed squarely at the AI data-center and electric-vehicle power boom. The question now: how much future growth is already priced in?
A Solid Beat, But Growth Is Still Modest
Q2 revenue hit $118.9 million, up 3% year-over-year and 10% sequentially.
Non-GAAP earnings of $0.37 per share topped the $0.32 consensus by $0.05, while revenue edged past the $117.4 million estimate.
Operating margins jumped 5.4 percentage points to 17.1% , partly thanks to a Q1 restructuring that cut costs and aligned expenses with revenue. Impressive execution — but 3% annual revenue growth barely outpaces inflation, meaning the stock's pop is really a bet on what comes next.
The Guidance Brackets Expectations, Not Blows Them Away
Management guided Q3 revenue to $122–$130 million with non-GAAP operating margins of 17%–19%.
The $126 million midpoint sits close to analyst estimates , meaning the outlook confirms recovery momentum without delivering a blockbuster surprise. Channel inventory fell to 7.3 weeks, returning to healthy levels , which removes a demand overhang but also means restocking tailwinds — demand pulled forward by distributors — are fading.
A Voltage Record Targets a $3.5 Billion Market — Years From Now The headline grabber: Power Integrations introduced what it calls the world's first commercially available 2,200-volt gallium-nitride power chip, pushing into voltage territory traditionally owned by silicon carbide.
Analyst firm Yole Group projects the power gallium-nitride market will reach $3.5 billion by 2031. But investors should temper enthusiasm: CEO Jennifer Lloyd called the 2,200-volt chip a "technology demonstration, not a launched product," adding that meaningful revenue is "several years away."
Automotive and Industrial Carry the Near-Term Story
Lloyd confirmed automotive revenue is on track to double this year, with a $100 million target in the 2029–2030 timeframe.
Industrial revenue grew 16% year-to-date , and the company secured a new gallium-nitride design win at a major Tier 1 auto supplier. These are real near-term revenue engines, but they must accelerate meaningfully to justify a stock that trades at a premium to chip peers on a modest ~$475 million annualized revenue base. The earnings beat buys credibility; sustaining the rally requires proof that the technology roadmap converts into dollars.
