What it is

Arm Holdings (NASDAQ: ARM), headquartered in Cambridge, UK, designs processor architectures and licenses the resulting intellectual property to semiconductor companies and device makers worldwide. It does not fabricate chips. Revenue flows from two streams: upfront architecture licence fees and per-chip royalties, averaging roughly US$0.05 per chip as disclosed in Arm's 2023 US SEC prospectus. In FY2025 (year ended 31 March 2025), revenue reached US$4.92B, up 23% year-on-year: royalties US$2.61B, licensing US$2.31B. Over 350 billion Arm-based chips have shipped in total; the architecture underpins approximately 99% of smartphones sold globally in FY2025.

History

Arm was incorporated on 12 November 1990 as a joint venture between Acorn Computers (UK), Apple (US), and VLSI Technology (US), commercialising the RISC processor Sophie Wilson and Steve Furber had designed for Acorn in 1983. It first listed on the London Stock Exchange and NASDAQ in April 1998 under then-CEO Sir Robin Saxby. In September 2016, Japan's SoftBank Group acquired Arm for US$32B, then the largest acquisition of a European technology company on record, and took it private. Nvidia (US) announced a US$40B buyout in September 2020, but UK, US, and EU competition regulators opposed the deal on national-security and market-concentration grounds; Nvidia abandoned it in February 2022. SoftBank re-listed Arm on NASDAQ on 14 September 2023, raising US$4.87B at a US$54.5B valuation, with SoftBank retaining roughly 90% of shares. Rene Haas took over as CEO in February 2022 and has since pushed the company beyond pure IP licensing toward compute subsystems and, as of March 2026, direct silicon.

Current state

As of mid-2026, Arm's architecture dominates smartphone CPUs and is expanding into cloud servers, automotive chips, and IoT devices. The Neoverse server line, launched in 2018, underpins Amazon Web Services Graviton, Microsoft Azure Cobalt 200, and Google Axion custom chips; by early 2026, nearly half of leading hyperscaler compute capacity ran on Arm-based designs. In March 2026, Arm unveiled the AGI CPU, a 136-core Neoverse V3 processor on TSMC's 3nm node, the company's first production chip in 35 years, with initial customer demand exceeding US$2B for FY2027-2028. Arm simultaneously released the first public specification of its Chiplet System Architecture (CSA), with 60-plus partner organisations engaged, positioning CSA as a die-to-die interconnect standard alongside UCIe.

Relationships

SoftBank Group (Japan) owns roughly 90% of Arm as of mid-2026 and is the controlling shareholder determining any further share sales. Arm's largest licensees, including Qualcomm, Nvidia, Apple, Samsung, and MediaTek, are simultaneously revenue contributors and competitive tension points: Arm's move into compute subsystems and direct silicon puts it in competition with the very companies whose royalties fund its business. The UK government has treated Arm as a strategically important national asset since the 2016 SoftBank deal, a consideration that shaped conditions on that sale and animated UK regulators' opposition to the Nvidia bid. At the manufacturing layer, Arm partners closely with TSMC, whose leading-edge nodes Arm specifies in its reference platforms and, as of 2026, in the AGI CPU itself.

What to watch

  • AGI CPU customer wins and whether major licensees renegotiate royalty terms or develop competing architectures as Arm enters the finished-silicon market directly.
  • SoftBank's pace of further share sales, which will test Arm's revenue multiple on public markets given a share price that has traded well above semiconductor-sector averages.
  • Whether Arm's Chiplet System Architecture gains adoption versus UCIe as the dominant chiplet interconnect standard.
  • Arm's royalty pricing power in next-generation AI accelerators, where Neoverse cores are embedded alongside GPUs and NPUs, expanding the royalty base but raising the stakes of per-chip licence terms.
  • Any regulatory intervention if a major technology company in the US or China attempts a controlling stake in the UK-headquartered company.
