Is China's RISC-V Pivot Undermining Arm's Growth Prospects?

Arm Holdings faces decelerating growth in China, its second-largest market contributing 19% of total sales, with revenue growth of only 7.5% in fiscal 2025. This slowdown is attributed to China's strategic pivot towards RISC-V architecture to reduce reliance on Western technology, offering cost advantages and design flexibility. Major Chinese tech firms are backing RISC-V, potentially impacting NVIDIA and AMD as well, who face similar challenges in the region's evolving semiconductor landscape, while ARM's stock trades at a premium with declining earnings estimates and a Zacks Rank #4 (Sell).

Analysis

Arm Holdings (ARM) is experiencing a notable slowdown in its Chinese operations, which constitute 19% of its total sales, evidenced by a mere 7.5% year-over-year revenue increase in fiscal 2025. This deceleration is directly linked to China's strategic push towards the open-source RISC-V chip architecture, a move aimed at reducing reliance on Western proprietary technologies like Arm's and enhancing domestic semiconductor capabilities through cost advantages and design flexibility. Key Chinese technology firms, including Alibaba, Huawei, Tencent, and ZTE, are actively supporting this transition, with domestic entities like Alibaba’s XuanTie and Nuclei System Technology spearheading RISC-V chip development, and RIVAI Technologies recently unveiling a high-performance RISC-V server chip, Lingyu. This shift not only pressures Arm's market share but also poses a competitive threat to NVIDIA and AMD, particularly in AI hardware, data centers, and server chip segments within China. Despite Arm's stock gaining 18% year-to-date, outperforming its industry, it trades at a steep forward price-to-sales ratio of 31.5, compared to the industry average of 8.1. Compounding these concerns, Arm carries a Value Score of F, has seen its Zacks Consensus Estimate for earnings decline over the past 60 days, and currently holds a Zacks Rank #4 (Sell), indicating significant headwinds.

Key Decisions for Investors

• Investors in Arm Holdings should consider the significant risks posed by China's RISC-V adoption, the company's high valuation, and declining earnings estimates, potentially warranting a re-evaluation of exposure.
• Closely monitor the adoption rate of RISC-V architecture and advancements in China's domestic chip capabilities, as these developments will directly impact Arm's, NVIDIA's, and AMD's future revenue and market share in this critical region.
• Factor in the escalating geopolitical tensions and China's drive for technological self-sufficiency as key risk considerations for semiconductor companies with significant China exposure, potentially adjusting strategic allocations accordingly.
