Arm Holdings plc American Depositary Shares (ARM) | The Buildout — AI Infrastructure

The Verdict

Arm owns the CPU instruction-set architecture and the design IP that nearly the entire mobile and embedded world is built on. That same architecture is now the foundation for the custom server CPUs hyperscalers design for themselves — NVIDIA's Vera, Google's Axion, AWS's Graviton5, Microsoft's Azure Cobalt. Arm supplies the CPU IP and pre-integrated compute subsystems those chips are built from, and earns a royalty as they ship. In March 2026 it also introduced its own production chip, the Arm AGI CPU, sold direct and through rack partners into the data center. That makes Arm a supplier to chip designers and, at the silicon layer, a competitor to some of them.

Earnings Beat

Arm reported record FY2027 Q1 revenue of $1.29 billion, up 22% year over year, at a gross margin of 97.2%. Royalty revenue rose 22% to $715 million and license and other revenue rose 23% to $574 million, both records. Trailing-twelve-month free cash flow was $1.47 billion.

Management tone: Management's tone on AI and silicon was confident and specific, and it hardened versus the prior call: the AGI CPU "moved from a demand-only story to a supply-backed story," with confidence in achieving upside to the initial opportunity having "increased in the past 90 days." On the negative side, management stated the smartphone deterioration plainly and quantified the guidance consequence directly, and described supply conditions bluntly: "a very, very, very tight world."

Management Guidance

For Q2 FY2027, Arm guided revenue of $1.38B ± $50M, license and other revenue up about 30% year over year, royalty revenue up low teens year over year (referenced as 13% in Q&A), non-GAAP OpEx of about $780M, and non-GAAP EPS of $0.47 ± $0.04. Full-year FY2027 royalty growth was trimmed to "closer to the high teens" from "roughly 20-ish percent," on smartphone memory inflation broadening beyond the low end. Management reaffirmed FY2028/FY2029 royalty growth of "20% plus" and held its FYE31 framework of $15B in AGI CPU revenue plus $10B in IP revenue, totaling $25B and more than $9 in EPS. First-generation AGI CPU gross margin is guided to the "high 30% range, maybe low 40s percent," with a path to 50% over a couple of years via insourcing; rest-of-year OpEx is guided to grow mid-single-digit percentage quarter on quarter. Formal AGI CPU revenue and margin detail is deferred to Q3 FY2027 results.

Trajectory

Revenue is growing but the sequential pace is decelerating. FY2027 Q1 revenue was $1,289 million, up 22% year over year but down 13.5% from the seasonally stronger FY2026 Q4. The driver is a mix shift inside the royalty line: data-center royalties more than doubled year over year for a second consecutive quarter, while smartphone weakness from memory-driven handset cost inflation pulled FY2027 royalty growth guidance down to the high teens. The computed signals show gross margin stable near 97%, with operating and EBITDA margins compressing. Cash conversion is healthy — trailing-twelve-month free cash flow of $1.47 billion is 141% of net income.

The Model

The model projects FY+1 revenue of $6,035 million with EBITDA of $1,282 million (21.25% margin), and FY+2 revenue of $8,155 million with EBITDA of $2,018 million (24.75% margin). The near-term is anchored by the IP and royalty business plus the first AGI CPU production revenue management guides to Q4 FY2027. FY+2 reflects a full year of AGI CPU revenue — the prior framework split the initial opportunity into roughly $90 million in Q4 FY2027 and about $910 million in FY2028 — alongside continued royalty growth.

Projections are the median of 4 independent model runs. The model’s revenue sits 4.3% below analyst consensus.

For Q2 FY2027, Arm guided revenue of $1.38B ± $50M, license and other revenue up about 30% year over year, royalty revenue up low teens year over year (referenced as 13% in Q&A), non-GAAP OpEx of about $780M, and non-GAAP EPS of $0.47 ± $0.04.

Formal AGI CPU revenue and margin detail is deferred to Q3 FY2027 results.

What Could Go Right — and Wrong

Looking Ahead

The next twelve months turn on execution of the AGI CPU and on whether cloud AI keeps covering smartphone weakness. Q3 FY2027 results are the stated checkpoint for a detailed AGI CPU revenue and margin update, with visibility into Q4 FY2027 and FY2028. First production revenue is guided to Q4 FY2027, concurrent with the 20-F's expectation of production by the end of calendar year 2026. Silicon revenue is slated to be broken out as a third reporting line in FY2028, once it reaches at least 10% of revenue.

The Company

Arm architects, develops and licenses high-performance, energy-efficient compute platforms built on the Arm architecture. More than 350 billion Arm-based chips have shipped cumulatively, and the ecosystem reaches more than 22 million developers. Its royalty revenue spans five end-markets: mobile applications processors, industrial IoT and embedded, consumer electronics, cloud AI, and physical AI. Mobile applications processors alone were about 43% of total royalty revenue in FY2026, but cloud AI is the largest driver of royalty growth as hyperscalers build custom server CPUs on Arm IP.

Arm is fabless and owns no fabs, data centers or power assets; for Arm, capacity means securing third-party supply. The 20-F discloses one named facility — the Cambridge, U.K. global headquarters, roughly 418,793 square feet of leased office space, with leases expiring between 2032 and 2044. In March 2026 Arm expanded from licensing into selling its own silicon with the Arm AGI CPU, its first Arm-designed production chip for the data center, sold direct and through rack partners. That step brings real cost of sales and third-party supply commitments to a business that previously carried neither.

Business Segments

Competitive Landscape

The FY2026 20-F states that Arm faces "competition primarily from other architectures like x86 and RISC-V in many of these markets," and references free, open-source technologies including RISC-V alongside established x86 technologies. Inside the data center the dynamic is layered: Arm supplies CPU IP and subsystems to chip designers, and several of those designers — Qualcomm, NVIDIA and the hyperscalers — are also building or announcing Arm-based server CPUs of their own. The intel file's labeled read is that this is good for the architecture and competitive at the merchant-silicon layer.

Supply Chain

Arm is fabless. It supplies IP and subsystems to chip designers and now also arranges third-party supply for its own AGI CPU. Chip manufacturing is concentrated among a limited number of companies in Taiwan and other parts of East Asia, per the 20-F.
