ARM reports record Q1 revenue of $1.29B, data center business doubles

ARM Holdings reported Q1 fiscal 2027 results on July 29, 2026, delivering record first-quarter revenue of $1.29 billion（約2100億円）, up 22% year-over-year. The growth was broad-based: royalty revenue rose 22% to $715 million（約1100億円） (a Q1 record), and licensing revenue climbed 23% to $574 million（約920億円） (also a Q1 record). Non-GAAP earnings per share increased 29% to $0.45, reflecting both top-line strength and operational efficiency. The company's non-GAAP operating margin expanded 200 basis points to approximately 41%, even as non-GAAP operating expenses increased 18% year-over-year to $733 million（約1200億円）, demonstrating that ARM is investing in growth while maintaining disciplined cost management. Free cash flow generation remained solid at $665 million（約1100億円） for the quarter and $1.4 billion（約2200億円） over the trailing twelve months.

The standout driver of growth is the data center business. Data center royalty revenue more than doubled year-over-year, fueled by accelerating adoption of ARM Neoverse cores (the company's processor architecture for servers and high-performance computing). This strength is anchored by extraordinary demand for ARM's new AGI CPU: the company reports that demand for the new part now exceeds $2 billion（約3200億円）, materially higher than the initial $1 billion（約1600億円） opportunity the company had previously guided. However, supply chain constraints are a significant headwind. ARM faces bottlenecks across wafers (silicon manufacturing capacity), substrates (the carrier material for chips), test capacity, and memory, which are limiting near-term revenue realization despite the strong demand signal. Additionally, gross margins on the initial AGI CPU generation are expected to land in the high-30% to low-40% range, below ARM's long-term 50% target, reflecting the typical margin profile of new product ramps and higher input costs.

The smartphone business, historically ARM's cash-generation engine, is facing cyclical headwinds. Smartphone market weakness driven by higher memory prices is impacting royalty revenue growth, and management has correspondingly lowered full-year royalty revenue growth guidance from approximately 20% to high-teens, a meaningful reduction. Annualized Contract Value (ACV) grew a more modest 13% year-over-year, and licensing revenue remains inherently lumpy due to the timing and size of major deals, creating quarter-to-quarter volatility.

Looking ahead, ARM guided second-quarter fiscal 2027 revenue to $1.38 billion（約2200億円） (plus or minus $50 million（約80億円）) and non-GAAP operating expenses of approximately $780 million（約1200億円）. These figures suggest the company expects continued sequential growth but at a moderating pace as it manages through smartphone softness and navigates AGI CPU supply constraints. Investors will be watching whether data center momentum can offset smartphone weakness, and whether supply chain improvements allow ARM to capture more of the $2 billion（約3200億円） AGI CPU demand in coming quarters.

ARM's Q1 fiscal 2027 performance reflects a company in transition: traditional licensing and smartphone royalties remain strong but are moderating, while the data center and AGI CPU business offer higher-growth potential. The doubling of data center royalty revenue signals sustained momentum in cloud and AI infrastructure, where ARM's energy-efficient cores appeal to hyperscalers (large cloud providers) building inference and training infrastructure. However, this transition carries near-term friction. Smartphone royalties, which historically provided steady cash flow, are under pressure from memory price inflation, forcing management to lower annual guidance from ~20% to high-teens growth. Meanwhile, the AGI CPU opportunity—where demand now exceeds $2 billion（約3200億円）—is constrained by supply chain bottlenecks (wafers, substrates, test, memory), meaning revenue upside may lag demand signals in the near term.

Operationally, ARM is demonstrating leverage: the non-GAAP operating margin expanded 200 basis points to 41% despite 18% operating expense growth (driven by R&D investment). Free cash flow remains robust at $665 million（約1100億円） quarterly and $1.4 billion（約2200億円） trailing twelve months, giving the company room to invest in product and navigate supply constraints. The margin compression on initial AGI CPU units (high-30% to low-40% vs. the long-term 50% target) is expected for a new product ramp and implies that peak margin expansion will depend on both volume recovery and supply chain normalization.
