Arm Holdings stock has been one of the standout performers of 2026. Shares nearly doubled from early March through early May, driven largely by investor enthusiasm around the company’s push into data center central processing units. Then came the fiscal Q4 earnings report on May 6. The results themselves were strong. Nevertheless, the stock pulled back afterward. Now the question on every investor’s mind is simple: does this dip represent an opportunity, or is caution the smarter play?
To answer that, it helps to understand what Arm actually does, what the numbers showed and where the risks lie.
What Arm Holdings does
Arm is a U.K.-based semiconductor intellectual property company. It designs the architecture that underpins how CPUs function. Its technology serves as an alternative to the x86 standard used by Intel and Advanced Micro Devices. Arm’s architecture appears in roughly 99% of high-end smartphones worldwide. Historically, the company has licensed its IP to customers through royalty or subscription agreements rather than manufacturing physical chips itself.
That model changed significantly earlier this year. Arm announced it would develop its own data center CPUs. The move surprised investors and set off the stock’s dramatic rally. Arm projects the data center CPU market will reach $100 billion within the next few years. Furthermore, it believes it can capture a 15% share of that market.
What the fiscal Q4 results showed
The numbers Arm reported for fiscal Q4 were genuinely strong across multiple metrics.
Total revenue climbed 20% year over year to $1.49 billion. License revenue jumped 25% to $819 million, driven by demand for next-generation architecture. That figure included a $200 million contribution from a Softbank agreement. Royalty revenue also grew 11% to $819 million. Within that, data center royalty revenue doubled. Arm noted particular strength in data processing units and SmartNICs, where it holds nearly 100% market share.
Even in smartphones, where the broader market showed weakness, Arm continued to grow revenue. Higher royalty rates from its newer Armv9 architecture helped offset softer overall handset volumes.
Looking ahead, Arm guided for fiscal Q1 revenue of approximately $1.26 billion, representing 20% year-over-year growth. Both royalty and licensing revenue are expected to grow at a similar pace. Adjusted earnings per share guidance came in at $0.36 to $0.44.
Management also reiterated its long-term targets. By 2031, Arm expects to generate $15 billion in CPU revenue and $10 billion in IP revenue. That trajectory implies roughly $9 in earnings per share. The company also said it has line of sight into more than $2 billion in CPU demand across fiscal years 2027 and 2028. However, supply constraints led management to maintain its $1 billion CPU revenue forecast for now, with revenue beginning in Q4 of fiscal 2027.
Where the risks come in
The growth story is real. However, so are the risks. Two stand out as particularly important for investors to consider.
First, supply constraints. Arm’s traditional IP model never required it to manage foundry capacity or component availability. Moving into physical CPU production changes that entirely. The company acknowledged that securing manufacturing capacity remains a limiting factor on near-term revenue. That is a new kind of execution risk for a business that has historically operated asset-light.
Second, smartphone exposure. Memory costs are rising, which could put pressure on handset sales broadly. Smartphones still represent a significant portion of Arm’s royalty revenue base. A meaningful slowdown in that segment would weigh on the overall business even as data center momentum builds.
Is Arm Holdings stock worth buying right now?
The long-term case for Arm is genuinely compelling. The rise of agentic AI is accelerating demand for data center CPUs. Arm-based chips, including Amazon’s Graviton and Alphabet’s Axion, are already gaining ground in that market. The company’s DPU and SmartNIC business adds another high-growth dimension to the story.
However, the stock currently trades at a forward price-to-earnings ratio of around 73 based on fiscal 2027 analyst consensus. That is a demanding valuation. It leaves little margin for error, particularly given the supply chain uncertainty and smartphone volume risks that could pressure near-term results.
For investors with a long time horizon and tolerance for volatility, the post-earnings dip may eventually look like a reasonable entry point. For those seeking a margin of safety at current prices, patience may be the wiser strategy.
