Arm Forecasts Slower Growth as AI Demand Fails to Offset Seasonality

For the fiscal fourth quarter, Arm Holdings expects revenue of approximately $1.47 billion, representing an 18% year-over-year increase. While this figure slightly exceeds analyst expectations, it marks a deceleration from the 26% growth recorded in the previous quarter. Chief Financial Officer Jason Child attributed the slowdown to typical seasonality and a high bar set by the previous year's release of a major chip from MediaTek, which provided a significant one-time boost to royalties.

The company’s third-quarter performance outpaced Wall Street estimates, with revenue climbing to $1.24 billion. Adjusted earnings reached 43 cents per share, beating the 41 cents predicted by analysts polled by FactSet. However, net profit slipped to $223 million, down from $252 million a year earlier, as the firm balances rising operational costs against its expanding market share in the data center sector.

Shifting to High-Value AI Silicon

Royalty revenue remains a critical pillar for the Cambridge-based firm, jumping 27% to $737 million in the latest quarter. This growth was fueled by higher royalty rates per chip and the rapid adoption of Arm architecture in AI-focused data centers. Chief Executive Rene Haas noted that demand for AI computing on the Arm platform continues to accelerate, signaling a shift toward higher-value licensing as customers transition to more advanced chip designs.

Despite the immediate post-market sell-off, which saw shares drop 8.3% to $96.12, management expressed confidence in long-term prospects. This optimism is supported by several structural shifts in the semiconductor market:

• A growing backlog of long-duration contracts at higher royalty rates.
• Increased adoption of the Armv9 architecture across mobile and cloud sectors.
• Rising demand for power-efficient designs specifically tailored for massive AI workloads.

License and other revenue also gained 25% to $505 million, though the company cautioned that this segment remains subject to normal fluctuations in the timing of large agreements. While the stock has faced a volatile year, the company maintains that its shift toward high-performance computing will sustain its valuation as AI deployment moves from experimental phases to core infrastructure.
