Arm Stock Plunges -- Smartphone Business Delivers a Major Disappointment

What happened

Arm reported fiscal second-quarter adjusted earnings of 52 cents per share and revenue of $1.44 billion, both above analyst estimates. Royalty revenue rose 8% to $670 million, below the $705 million analysts expected, as limited memory availability and higher prices weighed on smartphone production.

Confirmed

Global impact / market context

Arm collects royalty fees when customers use its technology in chips shipped inside devices, so fewer smartphones being produced can slow those payments. The shortfall shows how mobile-device supply constraints may offset stronger demand elsewhere, even when quarterly earnings and revenue exceed estimates.

Analyst inference

Data center royalties doubled from a year earlier, but overall royalty growth was weaker than analysts expected. The article also says Qualcomm flagged challenges involving Android and Apple modem-related revenue, suggesting smartphone production pressures may reach more than one chip-related business.

Analyst inference

What to watch

1. Watch whether memory availability and prices improve, since the article links those constraints to weaker smartphone production and slower royalty growth for Arm. Analyst inference
2. Watch Arm’s next royalty revenue results against expectations; continued shortfalls would indicate smartphone-related fees remain under pressure despite data center demand. Analyst inference
3. Watch whether data center royalties continue growing after doubling year over year, and whether that growth can offset slower fees tied to smartphones. Analyst inference
