Last Updated: 22 April 2026
Arm Holdings plc (NASDAQ: ARM) designs the CPU instruction-set architecture that powers more than 99% of the world's smartphones, every hyperscaler's custom server CPU (AWS Graviton, Google Axion, Microsoft Cobalt, NVIDIA Grace/Vera) and an accelerating share of AI data-centre, automotive and IoT silicon. The Cambridge-based company — still roughly 90% owned by SoftBank Group — licences blueprints rather than manufacturing chips, collecting an upfront licence fee and a per-chip royalty on every device shipped. Fiscal 2025 (ended 31 March 2025) revenue reached $4.01 billion, and Arm has now posted four consecutive billion-dollar quarters, culminating in Q3 FY26 revenue of $1.24 billion (+26% YoY) reported on 4 February 2026. On 24 March 2026 Arm took its biggest strategic turn in 35 years, launching the Arm AGI CPU — a 136-core Neoverse V3 data-centre chip it now sells as finished silicon, with Meta as lead customer and OpenAI, Cerebras, Cloudflare, F5, SAP, SK Telecom and others signed on. Yesterday (21 April 2026) SoftBank extended CEO Rene Haas's remit to also run SoftBank Group International, coordinating the group's semiconductor and AI portfolio.

3. What Does Arm Actually Do?
Arm designs — and licences — the CPU architecture (the instruction set) and the CPU cores themselves (Cortex, Neoverse), plus graphics (Mali/Immortalis), neural processing units (Ethos NPU), system IP and physical IP. Chip companies such as Apple, Qualcomm, MediaTek, Samsung, NVIDIA, AWS, Google and Microsoft take that intellectual property, add their own secret sauce, hand the design to a foundry (usually TSMC) and ship silicon. Arm owns no fab and manufactures no chips itself — historically. That changed on 24 March 2026 with the AGI CPU (see Section 7).
Revenue splits two ways:
- Royalty revenue — a per-chip fee paid on every Arm-based chip shipped, typically a small percentage of the chip's selling price. FY2025: $2.17bn (~54% of total, +20% YoY). Q3 FY26: $737m (+27% YoY).
- Licence & other revenue — upfront fees for access to architecture or specific IP blocks, plus software, tools and services. FY2025: $1.84bn (~46%, +29% YoY). Q3 FY26: $505m (+25% YoY). SoftBank itself is an ~$200m/quarter licensee.
Royalties are also split by end market. Arm reports that non-mobile segments (cloud/infrastructure, automotive, IoT) now account for more than half of total royalties, with mobile still the single largest category. Indicative mix (FY2025 commentary from company filings and investor presentations): Mobile/client ~45%; Infrastructure/data centre mid-20s; IoT/embedded mid-teens; Automotive mid-teens — exact percentages vary quarter-to-quarter. Cloud AI royalty has grown more than 100% YoY and is now described by management as the biggest individual growth driver.
4. The Business Model
Arm sells two things: upfront licences to its IP (architecture licences, TLAs, and bundled Compute Subsystems or CSS) and a royalty per chip that ships containing that IP. Licensing is lumpy and front-loaded; royalties compound for decades — customers that adopted Armv7 in the 2010s are still paying royalties today on products in the field.
- Per-chip royalty rates typically sit in the low single-digit-percent range of chip ASP. Armv9 commands roughly double the v8 rate; Compute Subsystems carry a further uplift because Arm delivers more of the design.
- Lifetime chip shipments: more than 350 billion Arm-based chips shipped cumulatively (as of Q3 FY26 commentary).
- Gross margin is structurally very high — FY2025 non-GAAP gross margin was ~97% because Arm has no fab, no materials cost and no logistics; the main operating cost is engineering payroll.
- CSS model: Arm delivers a ready-to-manufacture subsystem (CPU cluster plus physical implementation plus verification) instead of raw RTL. 21 CSS licences across 12 companies as of Q3 FY26; five customers already shipping CSS-based silicon.
- Moat: 40+ years of software ecosystem, instruction-set compatibility, partner toolchains and hundreds of thousands of engineers trained on Arm. Switching away is expensive and slow — hence why even RISC-V adopters typically still ship Arm in parallel.
- No government-credit dependency: unlike fabs (TSMC, Intel Foundry, Samsung) Arm does not rely on CHIPS Act or similar subsidies — it has no production assets to subsidise.
5. Financial Health
Annual trend (fiscal year ending 31 March; figures from filings and shareholder letters):
| Metric | FY2022 | FY2023 | FY2024 | FY2025 |
|---|---|---|---|---|
| Revenue | $2.70bn | $2.68bn | $3.23bn | $4.01bn |
| Royalty revenue | $1.54bn | $1.68bn | $1.80bn | $2.17bn |
| Licensing revenue | $1.16bn | $1.00bn | $1.43bn | $1.84bn |
| Non-GAAP gross margin | ~95% | ~96% | ~96% | ~97% |
| GAAP operating margin | ~26% | ~(28)% | ~(14)% | ~21% |
| Free cash flow | $757m | $750m | $760m | ~$178m |
| Headcount (period end) | ~6,250 | ~6,000 | ~7,100 | ~8,330 |
Quarterly trend (most recent five quarters, $ millions where not stated):
| Quarter | Revenue | Royalty | Licensing | Non-GAAP op margin | Non-GAAP EPS |
|---|---|---|---|---|---|
| Q3 FY25 (Dec-24) | $983m | $580m | $403m | ~48% | $0.39 |
| Q4 FY25 (Mar-25) | $1.24bn | $607m | $634m | ~43% | $0.55 |
| Q1 FY26 (Jun-25) | $1.05bn | $585m | $468m | ~39% | $0.35 |
| Q2 FY26 (Sep-25) | $1.14bn | $620m | $515m | ~41% | $0.39 |
| Q3 FY26 (Dec-25) | $1.24bn | $737m | $505m | ~41% | $0.43 |
Balance sheet remains net-cash. Non-GAAP operating profit was $505m in Q3 FY26 (+14% YoY). GAAP net income swings quarter-to-quarter on stock-based compensation. FY2025 free cash flow of roughly $178m was depressed by one-off tax and working-capital items; management reiterated that the underlying cash-conversion profile remains high. Management's Q4 FY26 guidance (issued 4 February 2026): revenue $1.47bn ± $50m (+18% YoY at midpoint), non-GAAP EPS $0.58 ± $0.04.
6. Valuation & Market Data
Market data as of 21 April 2026 close (source: Nasdaq / TradingView / stockanalysis.com).
| Share price | ~$175.49 |
| Market cap | ~$186.4bn |
| Enterprise value | ~$183.3bn |
| Shares outstanding | ~1.06bn ADS equivalent |
| Free float | ~136m shares (~10% of total) |
| P/E (trailing, GAAP) | ~234x |
| Forward P/E | ~82x–91x (depending on source) |
| P/S (trailing) | ~40x |
| EV/EBITDA (trailing) | ~169x |
| P/FCF (trailing) | ~191x |

| Dividend | None |
| Short interest | ~15.4m shares (~10% of float; ~1.5% of total shares out; short ratio ~2.2 days) |
Multiples are shown raw without judgement — they sit at the top of the large-cap semiconductor range because Arm's revenue model (near-100% gross margin, royalty compounding) is structurally unlike traditional chip companies.
7. What Are They Building?
Arm AGI CPU (March 2026) — the headline pivot. Announced 24 March 2026, the AGI CPU is Arm's first production silicon product in 35 years. Up to 136 Neoverse V3 cores on TSMC 3nm across two dies, all-core ~3.2GHz (3.7GHz boost), 300W TDP, 12-channel DDR5-8800 (>800 GB/s aggregate memory bandwidth, sub-100ns target latency). Meta is the lead customer and co-developer, pairing the AGI CPU with its proprietary MTIA training/inference accelerators. Additional launch partners include OpenAI, Cerebras, Cloudflare, F5, Positron, Rebellions, SAP and SK Telecom. Volume shipments: end of 2026. On the launch call management framed the opportunity as ~$1bn of revenue in 2028 scaling to roughly $15bn annually within five years.
Compute Subsystems (CSS). 21 CSS licences across 12 companies as of Q3 FY26 (two new licences signed that quarter). CSS is already "well into double digits" as a share of royalty mix and management expects it to head toward half of royalties over the next few years. Three CSS flavours currently: Infrastructure (for data centre / hyperscaler silicon), Client (flagship mobile, laptop), and Automotive.
Hyperscaler / data-centre momentum. Every major hyperscaler custom server CPU is Arm Neoverse: AWS Graviton 4 (shipping) and Graviton5 (announced December 2025 with 192 cores), Microsoft Cobalt 100 and the newly announced Cobalt 200 (132 cores), Google Axion, NVIDIA Grace and the newly announced Vera (88 cores). Arm Neoverse passed one billion cores deployed in Q3 FY26. Management's guide is that Arm's share in top hyperscaler new CPU deployments is heading toward 50%.
Client / mobile. Armv9.2-based Cortex-X925 (up to +41% AI uplift vs X4) and Immortalis-G925 GPU (+37% gaming performance, +34% AI) underpin 2025/2026 flagship smartphone SoCs and CSS for Client powers Windows-on-Arm laptops on TSMC 3nm. Arm Kleidi software libraries accelerate on-device AI inference.
Automotive. NVIDIA DRIVE AGX Thor uses Arm Neoverse V3AE as its CPU complex; MediaTek's Dimensity Auto Cockpit C-X1 pairs Armv9.2-A CPUs with an NVIDIA Blackwell GPU; Qualcomm Snapdragon Digital Chassis is Arm-based. December 2025: Rivian announced its third-generation Autonomy Computer on a custom Arm SoC — the first production car to ship Armv9. Tesla's forthcoming Optimus humanoid robot is powered by a custom Arm-based AI processor.
IoT and edge AI. Cortex-A320 (smallest Armv9-A core) and Ethos-U85 NPU target always-on AI at the edge.
Stargate. Arm is named as a core technology partner in the OpenAI / Oracle / SoftBank / MGX Stargate AI infrastructure project (up to $500bn commitments over four years). Stargate UK extensions were announced in late 2025.
8. Competitive Landscape
Arm competes on architecture (Arm vs x86 vs RISC-V), on IP blocks (Arm vs MIPS/SiFive/Tenstorrent/Alibaba Xuantie cores) and — now, since March 2026 — on finished silicon (AGI CPU vs AMD EPYC / Intel Xeon / Ampere / in-house hyperscaler parts). In the end markets Arm serves:
| Market | Arm position | Main competitor(s) |
|---|---|---|
| Smartphone application processors | >99% unit share | None at scale |
| Data-centre CPU (total) | ~15% share, rising | x86 (Intel + AMD ~75–80%), RISC-V (small) |
| Hyperscaler new-deploy CPU | Trending toward ~50% | AMD EPYC, Intel Xeon |
| Automotive SoCs (ADAS/IVI) | Dominant in infotainment and ADAS | x86 niche; RISC-V emerging |
| Embedded / IoT / MCU | Leading share in 32-bit MCUs | RISC-V (rapidly growing), legacy 8/16-bit |
| PC client (Windows-on-Arm + Mac) | ~15% and rising | x86 (still majority) |
At the global processor-architecture level the commonly cited unit-share split in early 2026 is roughly: Arm ~55%, x86 ~20%, RISC-V ~25%. RISC-V volumes skew to low-end MCU/IoT — ARM still dominates high-performance and smartphone.
Within Arm's own IP, Apple is a special case: its M-series / A-series chips use an Arm architecture licence — Apple designs its own cores but pays Arm royalties on each chip. Arm and Apple signed a long-term extension of that agreement in 2023. Qualcomm's Nuvia-derived Oryon cores are also architecture-licensed; that contract is the subject of the ongoing litigation (see Section 10).
9. Leadership and Ownership
Rene Haas — President and Chief Executive Officer since February 2022; previously ran Arm's IP Products Group. Joined Arm in 2013 from NVIDIA. From 21 April 2026, Haas additionally serves as Chief Executive Officer of SoftBank Group International (a limited, part-time role coordinating SoftBank's semiconductor and AI portfolio). He remains CEO of Arm and a SoftBank Group director. Reported total direct and indirect compensation at Arm is in the order of $24m annually (heavily equity-weighted); the 2023 IPO year included a one-off package reported at ~$69m.
Jason Child — Chief Financial Officer; joined Arm in October 2022 from Splunk.
Masayoshi Son — Founder, Chairman and CEO of SoftBank Group; as controlling shareholder via SoftBank he sets Arm's capital-structure strategy and is the driving force behind the Stargate and AI-infrastructure partnerships that Arm now supports.
Board & ownership. SoftBank Group holds approximately 89.9% of Arm's ordinary shares. Free float is roughly 136m shares (~10%). No dividend. Arm has not announced a buyback.

10. Risks and Challenges
- Customer concentration. Per the FY2025 20-F, Arm derived approximately 56% of total net revenue from its top five customers (including Arm China). Losing or disputing any single top customer is material.
- Qualcomm / Nuvia litigation. A Delaware jury found in Qualcomm's favour in December 2024; in October 2025 Judge Noreika issued a full and final judgment dismissing Arm's remaining claim and ruling Qualcomm did not breach the Nuvia architecture licence. Arm is appealing. A separate Qualcomm-v-Arm case alleging anti-competitive conduct was scheduled for trial in March 2026 — status as of publication: ongoing.
- RISC-V competition. RISC-V now represents ~25% of global processor unit share (up from essentially zero a decade ago) and is growing at >30% CAGR. China has adopted RISC-V as its preferred national architecture as a response to U.S. export controls on advanced Arm-based designs. SiFive, Tenstorrent and Alibaba's Xuantie are the leading commercial RISC-V core designers.
- China exposure. Arm's revenue from Chinese customers flows largely through Arm China, a partially-owned affiliate with a complex governance history. Ongoing U.S./UK export-control updates can constrain what designs Arm can licence into China. HiSilicon (Huawei) is notably absent from the customer list since U.S. restrictions.
- SoftBank overhang. SoftBank owns ~89.9%. Any secondary placing, collar, or margin-loan unwind would add supply to a tight ~10% free float and could move the share price meaningfully. SoftBank has not publicly announced any plan to reduce its stake.
- Valuation sensitivity. At ~40x sales and ~230x trailing earnings, very small changes to royalty growth or licensing timing can drive large moves in the share price.
- Channel conflict from AGI CPU. By shipping its own finished silicon Arm now competes with chip-design customers that also pay it royalties — a balancing act management will have to handle carefully.
- Concentration in AI data centre narrative. A significant portion of the growth thesis depends on continued hyperscaler AI capex. Any pause — or a shift toward purely accelerator-led architectures that de-emphasise CPU orchestration — would slow Arm's data-centre compounder.
