TL;DR — Arm posted record fiscal first-quarter revenue of $1.29 billion, up 22%, and free cash flow jumped 343% to $665 million. The stock still fell more than 8% because the FTC opened a formal antitrust probe into whether Arm’s new self-made AI chip gives it reason to squeeze the same licensees, including Apple, Qualcomm and Nvidia, that its whole business depends on.
Arm Holdings reported fiscal first-quarter 2027 revenue of $1.29 billion, up 22% year over year and roughly $20 million above analyst consensus. Free cash flow jumped 343% to $665 million. Adjusted earnings of $0.45 a share beat estimates. By most measures, it was the best quarter in the company’s history as a public company. The stock fell anyway: shares closed the regular session down 8.1% at $224.89 before the results even came out, then dropped another roughly 7% in after-hours trading once they did. The reason has less to do with this quarter’s numbers than with a question the Federal Trade Commission opened in May: whether Arm, now that it builds its own competing chips, still has an incentive to keep licensing its architecture fairly to everyone else.
The Licensing Business Nobody Is Debating
The core numbers are not in dispute. Royalty revenue came in at $715 million, up 22%, and licensing revenue reached $574 million, up 23%. Management said data center royalties more than doubled year over year, the clearest sign yet that Arm-based server chips, not just phones, are becoming a meaningful royalty stream. Operating margin on an adjusted basis expanded to 41.2%, up from 39.1% a year earlier.
Guidance for the next quarter came in ahead of expectations too: revenue of $1.38 billion at the midpoint against a $1.34 billion consensus, and adjusted earnings of $0.47 a share. None of that is what moved the stock.
The GAAP Gap Stock Comp Opened Up
Underneath the adjusted numbers, GAAP profitability is going the other way. GAAP operating margin fell to 7.1%, down from 10.8% a year ago, and GAAP earnings were $0.25 a share, roughly half the adjusted figure. The gap is stock-based compensation: $433 million in stock comp and associated employer taxes, up 47% from $295 million a year earlier, and now equal to 33.6% of revenue, up from 28.0%. Arm’s adjusted numbers strip almost all of that out. Investors reading only the headline beat would have missed that the cost of running the company, measured the way GAAP measures it, grew faster than the business did.
The Chip Business That Triggered a Federal Investigation
Arm’s first self-manufactured chip, a 136-core server processor built on TSMC’s 3-nanometer process, is the company’s biggest strategic shift since it went public. Customer demand has already exceeded $2 billion combined for fiscal 2027 and 2028, and management is targeting $15 billion in annual AGI CPU revenue by fiscal 2031. First production revenue is expected in the fiscal fourth quarter of 2027. The catch: first-generation gross margins on the chip are around 30%, well below the roughly 50% operating margin of the licensing business it’s built on top of, making the new business dilutive until it reaches real scale.
That’s the business the FTC opened a formal investigation into in May 2026. Regulators are examining whether Arm intends to “degrade or deny the CPU architecture licenses that Apple, Qualcomm, Nvidia, and hundreds of other customers depend on” now that it competes with them directly in data center chips. The structural concern is straightforward: Arm controls the instruction set architecture that its own competitors are contractually required to license from it. South Korea’s Fair Trade Commission and the European Commission are both applying additional pressure on the same question.
Arm spent two decades convincing every chipmaker on earth that it would never compete with them directly. The FTC is now investigating whether that promise still holds now that Arm makes its own chip.
What Wall Street Is Actually Pricing
The one-month decline that preceded this earnings report had already erased roughly 28% off Arm’s stock price from its peak, well before Wednesday’s beat. That’s not a valuation story about slowing royalty growth; the royalty and licensing numbers are accelerating, not decelerating. It’s a regulatory-risk story layered on top of a business already carrying one of the richest multiples among the AI infrastructure names peers like AMD trade at. If the FTC ultimately requires Arm to ring-fence its AGI CPU unit from its licensing terms, the dilutive margin problem on the chip side gets easier to model. If it doesn’t, the overhang on the stock likely doesn’t go away just because one quarter beat estimates.
Arm reports fiscal second-quarter 2027 results in late October, alongside whatever update emerges on the FTC’s timeline. The number that will matter most by then isn’t revenue growth, which nobody currently doubts. It’s whether regulators have said anything that changes how the licensing business and the chip business are allowed to sit inside the same company.
