Arm's licensing jumps 50%, but royalty growth lags

The move

Arm Holdings, majority owned by Masayoshi Son's SoftBank, reported fiscal second-quarter revenue of $1.443 billion, up 27% year over year, in a Nov. 4 earnings release. License and other revenue rose 50% to $773 million, while royalty revenue, which depends on how many chips using Arm's designs actually ship, rose 8% to $670 million. Non-GAAP diluted EPS was $0.52, up from $0.39 a year earlier. Arm guided to third-quarter revenue of $1.54 billion, plus or minus $50 million. Shares fell 5.28% on Nov. 4.

Why it matters

The gap between fast-growing licensing revenue and slower royalty growth suggests demand for Arm's AI and data-center chip designs is real, but the payoff that comes once those chips actually ship in volume is still some way off.

The bear case

A 27% overall revenue gain, with license revenue up 50%, is still a strong quarter by most companies' standards, and licensing revenue is naturally lumpier from one quarter to the next.

What to watch

Whether royalty revenue accelerates as new data-center and AI chip designs now in the licensing pipeline move into volume production.

Masayoshi SonIPO / MarketsAI & techARM · SFTBYAI read · ▼ AI spending jitters

Arm falls 10% in AI selloff, hitting Son's biggest asset

The move

Arm Holdings shares fell about 10% on Oct. 30, caught in the same selloff that hit AMD, Dell and Marvell after Amazon's and Intel's earnings a day earlier deepened doubts about AI infrastructure spending. SoftBank, led by Masayoshi Son, owns the large majority of Arm and has borrowed billions of dollars against its Arm shares to fund other AI investments, including in OpenAI.

Why it matters

The drop lands directly on one of SoftBank's biggest assets, at a time when Son has leaned on Arm's share price to back a margin loan funding other AI bets.

The bear case

A one-day swing in Arm's share price doesn't change SoftBank's underlying stake, and the stock remains far above where it traded a year ago.

What to watch

SoftBank's fiscal second-quarter results, due November 10.

Masayoshi SonLegalAI & techARM · QCOMAI read · — Pyrrhic win for Qualcomm

Jury finds Arm breached Qualcomm license, awards $2

The move

A Delaware federal jury ruled on Oct. 13 that Arm Holdings, majority-owned by Masayoshi Son's SoftBank, breached its architecture license agreement with Qualcomm by withholding software patches and tools, and that Arm intentionally interfered with Qualcomm's relationship with Meta. The jury awarded Qualcomm only $2 in nominal damages and ruled for Arm on five other claims. A separate, potentially larger royalty dispute between the two companies now goes to the judge.

Why it matters

It's a narrow, low-dollar win for Qualcomm in a long-running fight that could still affect how much Arm collects in chip-design royalties.

The bear case

The damages were trivial and the jury rejected most of Qualcomm's other claims, so the practical impact on Arm's business may be limited until the royalty ruling.

What to watch

Judge Maryellen Noreika's ruling on the remaining royalty dispute.

Masayoshi SonLitigationAI & techARMAI read · ▼ Legal setback

Jury finds Arm breached its Qualcomm license deal

The move

A federal jury in Delaware ruled that Arm breached its chip-architecture license agreement with Qualcomm, interfered with a Qualcomm customer relationship, and violated California's unfair-competition law; Arm won one separate licensing claim. Arm shares fell as much as 5-7% in the sessions after the verdict, alongside a broader chip-stock slide.

Why it matters

SoftBank owns the majority of Arm, so the ruling is a direct legal and financial setback for Masayoshi Son's biggest AI-era bet.

The bear case

Arm still won one of the claims at trial, and a related bench trial over its newest architecture licensing could still go either way.

What to watch

Closing arguments in that related bench trial, scheduled for the week of October 19.
