👉 Breaking Down Arm Holdings ($ARM)

In partnership with

Hi everyone,

Today we’re breaking down the company whose technology runs in over 95% of the world’s smartphones and just launched its first chip in 35 years. The stock crossed $300 for the first time in late May, $400 for the first time last week… and now the market cap sits around $380B, with shares up over 210% year-to-date.

This stock is a monster.

As a reminder, this specific deep-dive is written by the GRIT team and is not the exclusive work of Head Analyst Austin Hankwitz.

Arm Holdings is the architecture layer of modern computing. Almost every smartphone in the world runs on Arm, every Apple Mac, every Nvidia Grace Blackwell server, every AWS Graviton instance, every Microsoft Cobalt deployment. Arm doesn’t make those chips. It designs the CPU blueprints, licenses them to chipmakers, and collects a royalty on every chip shipped. It’s one of the highest-quality recurring revenue businesses in technology, and after 35 years as a pure IP licensor, it just announced it’s going to start making its own chips.

The numbers are extraordinary. FY2026 revenue hit a record $4.92B (+23% YoY), the third straight year of 20%+ growth since the September 2023 IPO. Q4 was a record $1.49B with licensing up 29% and data center royalty more than doubling YoY. Non-GAAP operating margin was 49% in Q4 and 43% for the year. Gross margins are above 97%. The company exited FY2026 with $1.66B in annualized contract value (+22% YoY), $882M in free cash flow, and a mostly net-cash balance sheet.

The debate is about the bet now reshaping the company. In March 2026 Arm announced the AGI CPU, a 136-core 3nm data center processor co-developed with Meta, breaking a 35-year promise of architectural neutrality. Management is guiding to $15B in AGI CPU revenue and $10B in IP revenue by FY2031 ($25B total, $9+ EPS). Bulls call it the largest TAM expansion in semiconductor history. Bears point to an FTC antitrust investigation, ~90% SoftBank ownership, and a 140x forward earnings multiple. The stock just hit a fresh all-time high, but the next 18 months will determine whether the bet works.

Why Now? 👉 The AGI CPU Bet and Data Center Inflection

For most of its 35-year history, Arm was a quiet IP licensor known for smartphones. The AI buildout has rewritten the story. Power has become the gating factor on AI data center buildout, and Arm-based CPUs are roughly 50% more energy efficient than x86 at equivalent performance. That advantage has driven Neoverse, Arm’s data center platform, to nearly 50% share at top hyperscalers, with over 1B Neoverse CPUs deployed.

The catalyst is twofold. First, royalty rates per chip are structurally rising as customers upgrade to Armv9 and to Compute Subsystem (CSS) licenses, which include pre-integrated blueprints commanding higher rates. CSS has gone from concept to 21 signed licenses across 12 major customers in under two years.

Second, the AGI CPU announcement in March 2026 marked Arm’s pivot from pure IP licensor to direct chip vendor. The AGI CPU is a 136-core processor on TSMC 3nm, co-developed with Meta. Arm claims 2x performance per rack versus x86 and up to $10B in AI capex savings per gigawatt. Sample shipments are due by end of 2026, volume in 2027. If even half of management’s $15B FY2031 AGI CPU revenue target materializes, it’s the largest organic TAM expansion in Arm’s history.

Overview 👉 What Does Arm Do? Role in Ecosystem

Arm Holdings was founded in 1990 in Cambridge, UK and is still headquartered there with roughly 8,000 employees. The company designs CPU architectures and increasingly entire compute platforms, then licenses that IP to chipmakers who manufacture the actual silicon. Customers include Apple, Qualcomm, Nvidia, MediaTek, Samsung, AWS, Google, Microsoft, and hundreds of others. CEO Rene Haas has run the business since February 2022 and is the architect of both the IPO and the AGI CPU pivot.

Arm’s technology is in 99% of smartphones, the majority of consumer and automotive electronics, and a growing share of data center servers. Over 300B Arm-based chips have shipped cumulatively, with roughly 30B per year. Every iPhone, every Apple Mac since 2020, every Nvidia Grace Blackwell server, every AWS Graviton, every Google Axion VM, and Microsoft Cobalt all run on Arm.

Arm has been a SoftBank holding since the $32B take-private in 2016. Nvidia tried to acquire it for $40B in 2020, blocked by regulators in 2022. SoftBank re-IPO’d Arm in September 2023 at $51 per share and still owns approximately 90% of outstanding shares, making Arm a controlled company with limited float. SoftBank also owns Ampere Computing, an Arm-based server CPU maker, which raises an ongoing question about whether Arm’s direct silicon strategy conflicts with sister-company customer relationships.
