Arm Stock Slips Despite Record Quarter: A Royalty Miss Spoils the Beat

Arm Holdings beat Wall Street on revenue and profit and posted a record second quarter — yet its shares slipped about 2% in extended trading on Wednesday, November 4, 2026. The reason was hiding inside the beat: royalty revenue, the money Arm collects on every chip shipped with its designs, came in well below what analysts expected, even as licensing revenue surged.

What happened

Arm reported total revenue of $1.44 billion for its fiscal second quarter, which ended September 30, 2026. That was up 27% from a year earlier, marked the company's highest-ever second quarter, and beat the $1.38 billion average analyst estimate compiled by LSEG. Adjusted earnings came in at $0.52 per share, ahead of the $0.47 per share analysts expected. It was Arm's fifth consecutive quarter of total revenue growth above 20% year over year.

The split between Arm's two businesses told the real story. Licensing and other revenue jumped 50% year over year to $773 million, far above estimates of about $625 million — a strong signal, because today's licensing deals become tomorrow's royalty streams. Royalty revenue, by contrast, rose just 8% to $670 million, missing estimates of $720.8 million. Investors focused on that miss, and the stock slipped in after-hours trading despite the headline beat.

Why it's blowing up

Arm sits at the center of the AI buildout without making chips itself. It licenses processor designs and collects a royalty on nearly every smartphone chip and a fast-growing share of data-center processors. That makes its royalty line one of the cleanest reads on real AI hardware demand — and Wednesday's numbers gave both bulls and bears something to point to.

For the bulls, data-center royalties doubled year over year, and Arm said its share of servers at the top hyperscalers has more than tripled, from 15% in calendar 2024 to more than 50% in calendar 2025, with the company expecting that share to exceed 60% by the end of calendar 2026. Physical AI royalty revenue — chips for driver-assistance and in-vehicle systems — grew 50% year over year. For the bears, the royalty miss raised a familiar question: if AI demand is so strong, why did the per-chip business grow only 8%?

What's next

Arm's own guidance says the story is not over: a $1.54 billion revenue forecast for the current quarter would be another record pace, and management said its confidence has increased over the last 90 days on added supply, customer mix and growing commitments. The test for the next few quarters is whether the licensing surge converts into faster royalty growth — especially in data centers, where Arm's royalty base is doubling but still building. If royalties re-accelerate toward the licensing trend, Wednesday's dip will look like a pause in a record run. If royalty growth stays in single digits while licensing cools, the after-hours reaction may prove to be the market's early warning.
