What are Arm Holdings's biggest acquisitions?

Arm Holdings's largest disclosed acquisition here is Artisan Components for $913M in 2004. This page covers 4 major deals from 2004 to 2018, each with its price where disclosed and the reason behind it.

Major deals covered: 4
Largest deal: Artisan Components ($913M)
First deal: 2004
Most recent: 2018

Company	Year	Price	Purpose
Artisan Components	2004	$913.0M	Arm acquired Artisan Components, a designer of physical IP, for about $913 million in stock and cash. Physical IP covers the foundry-specific standard cell libraries, memory compilers and input and output cells a designer needs to turn a processor design into silicon on a particular manufacturing process, so the deal extended Arm from processor architecture into design enablement.
Apical	2016	$350.0M	Arm bought Apical, a Loughborough-based imaging and embedded computer vision company, for $350 million in cash in May 2016. Apical's image signal processing and display technology had already shipped in more than 1.5 billion smartphones, and Arm wanted it for vehicles, security systems, robotics and other devices that need to interpret what a camera sees.
Treasure Data	2018	$600.0M	Under SoftBank ownership Arm acquired Treasure Data, a cloud-based enterprise customer data platform, in a deal Bloomberg reported at about $600 million. The rationale was SoftBank's view of Arm as an end-to-end IoT company: Arm processors at the edge, Treasure Data collecting and analysing the resulting data in the cloud.
Stream Technologies	2018	Undisclosed	Arm acquired Stream Technologies, a Glasgow company specialising in cellular IoT connectivity management, for an undisclosed sum in 2018 and combined it with its Pelion device management platform. The aim was to sell connectivity, device management and data services to IoT deployments rather than only the processor designs inside the devices.

What companies has Arm Holdings bought?: Major acquisitions by Arm Holdings documented here include Artisan Components (2004), Treasure Data (2018), Apical (2016) and Stream Technologies (2018).
What is Arm Holdings's most recent acquisition?: The most recent Arm Holdings acquisition documented here is Treasure Data, in 2018, for $600M.

Treasure Data

2018

$600M

Why

Under SoftBank ownership Arm acquired Treasure Data, a cloud-based enterprise customer data platform, in a deal Bloomberg reported at about $600 million. The rationale was SoftBank's view of Arm as an end-to-end IoT company: Arm processors at the edge, Treasure Data collecting and analysing the resulting data in the cloud.

Impact

Treasure Data sat awkwardly next to a licensing business with no consumer or enterprise software channel of its own. It brought subscription software revenue but neither the customers nor the economics matched the rest of Arm, and investors questioned the price.

Outcome

Arm distributed Treasure Data to its shareholder in 2021 and reported it as a discontinued operation, alongside the Pelion IoT business. The two disposals produced net losses from discontinued operations of $127 million in fiscal 2022 and $156 million in fiscal 2021, and cleared the way for the pure IP story Arm took to the Nasdaq in 2023.

Stream Technologies

2018

Why

Arm acquired Stream Technologies, a Glasgow company specialising in cellular IoT connectivity management, for an undisclosed sum in 2018 and combined it with its Pelion device management platform. The aim was to sell connectivity, device management and data services to IoT deployments rather than only the processor designs inside the devices.

Impact

Stream added SIM and connectivity management to Pelion and gave Arm a recurring software revenue line, but the market was crowded by cloud providers offering comparable IoT device management, and scale never arrived.

Outcome

Arm sold Pelion IOT Limited to SoftBank Group Capital Limited in November 2021 and classified it as a discontinued operation. The retreat from IoT platform software under Rene Haas returned management attention to processor IP, data center designs and, later, Arm's own silicon.

Apical

2016

$350M

Why

Arm bought Apical, a Loughborough-based imaging and embedded computer vision company, for $350 million in cash in May 2016. Apical's image signal processing and display technology had already shipped in more than 1.5 billion smartphones, and Arm wanted it for vehicles, security systems, robotics and other devices that need to interpret what a camera sees.

Impact

Apical gave Arm a camera and display IP line to sell alongside its CPUs and GPUs, and an engineering team in computer vision at the point when on-device inference was becoming a licensing argument. The technology was folded into Arm's Mali camera and display products.

Outcome

The imaging work became part of Arm's client and automotive platforms and sits in the same product families that now carry the Lumex and Zena names. Unlike the IoT software purchases of the same era, it stayed inside the company.

Artisan Components

2004

$913M

Why

Arm acquired Artisan Components, a designer of physical IP, for about $913 million in stock and cash. Physical IP covers the foundry-specific standard cell libraries, memory compilers and input and output cells a designer needs to turn a processor design into silicon on a particular manufacturing process, so the deal extended Arm from processor architecture into design enablement.

Impact

The purchase gave Arm a second licensing product line and direct relationships with foundries including TSMC and Samsung. It let Arm offer processor designs together with the physical blocks needed to implement them on a given process node, which shortened customer time to market and broadened what Arm could charge for.

Outcome

Arm ran the business for two decades and then sold it: the Artisan foundation IP business, consisting of standard cell libraries, memory compilers and general-purpose input and output blocks, was sold to Cadence Design Systems on August 26, 2025 for $127 million of proceeds and a pre-tax gain of $131 million. The sale narrowed Arm back toward processor IP and its own silicon.

Arm Holdings's Growth & Acquisition Strategy

With more than 99% of mobile application processors already on its architecture, Arm is pushing into markets where the chip value per unit is higher. Neoverse designs target cloud and AI infrastructure and are the basis of Amazon Graviton, Google Axion, Microsoft Cobalt and Nvidia Grace; Arm says data center royalties more than doubled in fiscal 2026. Compute Subsystems, pre-integrated blocks rather than single cores, raise the content Arm sells per design, and in March 2026 Arm went further and began selling finished silicon with the AGI CPU for AI data centers. In automotive, Arm licenses safety-capable cores for infotainment and driver assistance, where its share is highest, and the platform families introduced in 2025, Neoverse for infrastructure, Niva for PCs, Lumex for mobile, Zena for automotive and Orbis for IoT, are how it packages that work for each market.

How Arm Holdings Makes Money

Arm licenses intellectual property. It spends heavily on R&D to design power-efficient processor architectures, then licenses the designs to companies such as Apple, Qualcomm and Samsung, which customize them and have them manufactured by a foundry such as TSMC. Arm charges an upfront license fee and an ongoing royalty on each chip shipped. In fiscal 2026 royalty revenue was $2,613 million and license and other revenue was $2,307 million.

What is Arm's current M&A philosophy following its 2023 public listing?

Arm has shifted from buying adjacent software businesses to reshaping its own portfolio: it sold the Artisan foundation IP business to Cadence Design Systems in August 2025 for $127 million, taking a $131 million pre-tax gain, and put the proceeds of that focus into processor IP, compute subsystems and its own data center silicon.

Who owns Arm?

Arm was famously acquired by the Japanese conglomerate SoftBank for $32 billion in 2016, and went public again in 2023 after regulators completely killed a massive buyout attempt by Nvidia.
