Arm's Q2 Results: CPU Renaissance Fuels Lucrative Path
Arm Holdings reported a strong second quarter, with revenue increasing 20% to $1.49 billion, beating analyst expectations. The company's positive outlook is underpinned by the industry-wide shift in AI workloads from GPU-centric training to CPU-intensive inference and agentic tasks. Major hyperscalers like Google, Amazon, and Nvidia are increasingly integrating Arm-based CPUs into their advanced hardware stacks. Furthermore, Arm unveiled its first in-house data center CPU, boosting future revenue projections to over $2 billion by 2028. Despite an immediate stock dip, the report confirms Arm's central role in the burgeoning CPU market.

Arm Holdings reported a better-than-expected second quarter, signaling a strong resurgence in the central processing unit (CPU) market, particularly within data centers. Despite an immediate dip in stock price following the announcement, the company maintained an optimistic outlook driven by AI workload shifts.
Quarterly Financial Performance
Arm's financial results for the fiscal 2026 quarter, ending March 31, showed significant year-over-year growth:
Revenue: Increased 20% year-over-year to $1.49 billion, surpassing the analyst consensus estimate of $1.47 billion.
Non-GAAP EPS: Rose 9% to 60 cents, beating the expected 58 cents.
The Shift: CPU Dominance in AI Workloads
The core narrative supporting Arm is the evolving nature of Artificial Intelligence (AI) workloads. The industry is moving beyond initial training phases, which heavily relied on Graphics Processing Units (GPUs), toward inference and continuous, agent-driven tasks.
Industry Validation: Competitors like Intel and AMD have highlighted this shift. Intel noted that the CPU-to-GPU ratio in AI racks is shifting from 1-to-8 to closer to 1-to-4, potentially reaching parity (1-to-1) in the future.
Market Potential: AMD CEO Lisa Su anticipates the CPU server total addressable market will grow at over 35% annually, potentially exceeding $120 billion by 2030.

Arm's Strategic Advantage and Market Penetration
Arm is positioned at the center of this CPU revival due to its licensing model and its increasing adoption by major cloud providers (hyperscalers).
Hyperscaler Adoption: Arm-based CPUs account for over 50% of the share among the top hyperscalers. Key examples include:
Nvidia's Rubin GPUs integrated with Vera (Arm-based) CPUs.
In-House Development: Arm unveiled its first in-house data center CPU, specifically designed for agentic AI workloads. Management has significantly increased its demand forecast for this product, now projecting over $2 billion in customer demand through fiscal year-end 2027 and 2028.
Financial Deep Dive and Outlook
Beyond the core licensing business, Arm's internal chip development provides a new revenue stream. The company's strong margins reflect its current licensing model:
Gross Margin: Reported at 98.32% (non-GAAP basis).
Guidance: For Q1 FY2027, Arm projects revenue of $1.26 billion (range: $1.255B to $1.265B) and non-GAAP EPS of 40 cents (range: 36c to 44c).
While the stock experienced an after-hours pullback, analysts view the strong fundamentals and the strategic pivot toward proprietary silicon as solidifying Arm's long-term growth thesis.
