What Happened?

Monolithic Power Systems (MPWR) signed the kind of agreement on September 9 that answers the biggest doubt hanging over the stock. The company and GlobalFoundries (GFS) announced a long-term deal to run MPS’s own process technology inside GF’s advanced 300mm fab in Singapore, with volume production targeted for early 2027. For a fabless chipmaker whose revenue is compounding faster than almost anything in analog, the worry was never demand. It was whether MPS could build enough to meet it. Shares closed at $1,234.46 on September 11, up 4.08%, though that day’s gain says more about the tape than the deal: it came two sessions later, during a broad AI-infrastructure rally that lifted server and chip names across the board after Oracle’s capital-spending guidance. MPWR rode that wave rather than leading it.

That worry is real because MPS has told investors for two quarters that it is running short of room. Management extended its capacity goals “significantly beyond $6 billion” on the Q2 call, and CEO Michael Hsing spent much of that call describing how hard scaling has become as the company shifts from selling chips to selling assembled power modules. The GlobalFoundries deal is the first concrete outside answer to that problem, and it lands with the stock still about 28% below its 52-week high of $1,714.09.

A Fab Deal That Buys Insurance for the AI Ramp

The agreement deploys MPS’s proprietary process technology at GF’s Singapore facility, with products expected to include power solutions for automotive architectures, industrial robotics and automation, and smart power stages for AI and cloud infrastructure. In plain terms, MPS gets qualified, geographically diversified capacity for exactly the products driving its growth, without owning the fab. According to the company’s investor relations materials, MPS runs a fabless model and leans on partners for manufacturing, so adding a marquee 300mm partner raises the ceiling on future revenue.

This is a signed long-term manufacturing agreement, and volume production is an early-2027 event. So it moves no 2026 revenue. What it does is reduce the risk that supply caps the story in 2027 and beyond. The value is strategic, not a same-day earnings jolt: a known bottleneck got wider.

On the Q2 call, Hsing was blunt that the back-end assembly side is the harder problem now, not the silicon. “It’s a 3D effect. It’s more complicated than you assemble a phone even,” he said of module assembly, adding the company must “pull some more new tricks in the next year or so to increase all these capacities.” When the founder says the constraint is manufacturing, a manufacturing partnership is the response investors wanted.

The Demand That Made Capacity the Question

MPS reported record Q2 2026 revenue of $980.64 million on July 30, up 47.6% year over year and nearly 22% sequentially, beating the Street’s $903 million estimate by more than 8%, with adjusted earnings of $6.50 against a $5.88 consensus. The engine was Enterprise Data, the AI server and data center power segment, which grew 45% sequentially, and management raised its full-year growth floor there from 85% to 130%. Hsing framed the through-line simply on the call: “in our history, when we mention something, it will turn into a revenue.” 

Analysts moved in the same direction after the print. KeyBanc lifted its target to $2,100, Needham to $2,000, and Truist to $1,889, StoneX initiated at Buy on September 2 citing best-in-class margins, and Stifel reiterated Buy in September specifically on capacity growth, the exact thread the GlobalFoundries deal pulls.

MPWR trades near 38.5 times next-twelve-month earnings, well above Texas Instruments near 28x, Analog Devices around 24x, and ON Semiconductor near 20x. That gap is defensible only if MPS keeps pairing sector-leading growth with a gross margin above 55%, which is exactly why capacity news is more than a footnote.

Using TIKR’s mid-case scenario, the model values MPWR at around $2,495 by the end of 2030, roughly 102% total upside and near 18% annualized. That case rests on about 19% annual revenue growth, carried by two drivers the quarter already showed: Enterprise Data power content rising as AI rack density climbs, and a broadening automotive footprint, with more than 1,500 new sockets shipped so far this year across ADAS and other in-vehicle systems. The margin driver is net income margin holding in the low-30s as higher-value module sales scale. The primary risk is the mirror image: MPS sits at the low end of its own gross margin model, and capacity ramps plus module mix could pressure profitability before they lift it.

  • Upside case: GlobalFoundries capacity comes online cleanly, Enterprise Data holds its raised triple-digit growth floor, and the multiple stays intact on durable AI demand.
  • Downside case: AI order visibility, which management admits is shorter than a full year, softens into 2027 and leaves a ~38x multiple exposed.

The Street’s mean target near $1,840 sits well below the model’s mid case, so this is a scenario built on stated assumptions, not a promise. The gap between the two is the argument to work through yourself.

Conclusion

The next real test is the Q3 2026 report, due in late October or early November, where management guided to roughly 56% year-over-year revenue growth. The number that decides whether the capacity story is working is Enterprise Data: hold near the raised 130% pace and the GlobalFoundries deal reads as the supply insurance that makes 2027 estimates credible. Slip, and a premium multiple with admittedly short visibility becomes the story instead.
