Arm Holdings posts record quarterly revenue, and the stock falls anyway

Arm Holdings just delivered the biggest quarter in its history. Investors responded by selling the stock.

The British chip designer reported fiscal second-quarter 2027 revenue of $1.44 billion on November 4, 2026, up 27% from a year earlier. Shares slid in after-hours trading and kept sliding over the following sessions, with declines ranging from approximately 5% to 11% at various points.

The numbers behind the record

This marks the fifth straight quarter in which Arm grew revenue by more than 20% year over year.

The standout was licensing and other revenue, which jumped 50% to $773 million. Royalty revenue rose a more modest 8% to $670 million.

Licensing revenue is what companies pay upfront for access to the blueprints. Royalties are the small fee Arm collects on every chip that eventually ships using its designs.

On the profit side, adjusted earnings per share climbed 33% to $0.52, beating Wall Street consensus. GAAP net income, however, fell to $130 million despite the top-line growth.

Why Wall Street hit the sell button

Royalty revenue missed estimates, and that is the number that reflects real-world chip shipments over time.

Guidance did not offer much of a cushion either. Arm forecast third-quarter revenue of $1.54 billion, plus or minus $50 million, and non-GAAP EPS of $0.56, plus or minus $0.04.

There is also a lingering worry about smartphones. Ongoing pressure in the handset market has fed concerns about how much momentum royalties can sustain, given how much of Arm’s legacy business is tied to phones.

The AI infrastructure bet

Data center royalties doubled year over year.

CEO Rene Haas pointed to growing demand for AI infrastructure as a major driver of Arm’s business going forward.

Arm’s share among the top hyperscalers exceeded 50% in calendar year 2025. The company expects that figure to surpass 60% by the end of 2026.

Arm expects Arm AGI CPU revenue to reach up to $2 billion across fiscal 2027 and 2028, citing newly secured purchase orders and supply agreements.

Arm’s partners shipped more than 10 billion Arm-based chips during the quarter, a new record.

What this means for Arm investors

Licensing growth of 50% signals that customers are lining up for Arm’s designs, often for next-generation and AI-focused chips. But licensing is a leading indicator, not a paycheck that repeats. The market wants proof that today’s licensing boom becomes tomorrow’s royalty stream, and an 8% royalty increase alongside a miss on estimates did not provide that proof this quarter.

The GAAP profit decline is another item to track. If reported earnings keep diverging from adjusted earnings, scrutiny of Arm’s cost structure will likely intensify.

The next checkpoint is the third quarter. Arm will need to land inside its $1.54 billion revenue range, and royalty performance will likely get more attention than any other line on the report.
