Ampere Computing Acquisition
Ampere Computing was acquired by SoftBank for $6.5B on 20 March 2025.
Before the acquisition Ampere Computing had raised $514M across 4 funding rounds.
Ampere Computing, a Santa Clara-based semiconductor design company founded in 2017 by Renée J. James, specializes in high-performance, energy-efficient ARM-based processors for cloud-native computing, data centers, and sustainable AI workloads, employing around 1,000 engineers and advancing its AmpereOne roadmap. SoftBank Group Corp., a Japanese conglomerate and majority shareholder in Arm Holdings, acquired Ampere for $6.5 billion (approximately ¥973 billion) in an all-cash transaction announced on March 19, 2025, through its subsidiary Silver Bands 6 (US) Corp., with Carlyle and Oracle selling their stakes. The deal positions Ampere as a wholly owned subsidiary retaining its name and operations, financed partly by borrowings from Mizuho Bank, amid SoftBank's AI infrastructure push including ventures like Cristal Intelligence, Stargate, and Graphcore. SoftBank's strategic rationale centers on accelerating artificial super intelligence through Ampere's semiconductor expertise, integrating it with the Arm ecosystem and group companies to enhance high-performance computing for AI and cloud markets. The transaction, approved by SoftBank's board on March 17, 2025, closed on November 25, 2025, after regulatory approvals, with Ampere's financials now consolidated into SoftBank's statements; the impact on consolidated results remains under review. Masayoshi Son emphasized Ampere's role in U.S. AI innovation, while James highlighted alignment on AI advancement and the AmpereOne processor roadmap. The acquisition strengthens SoftBank's control over energy-efficient data center chips amid rising demand for scalable AI compute, complementing its Arm and Graphcore holdings to build an integrated ecosystem, with positive market reaction including SoftBank shares rising up to 8% post-closure.

Ampere Computing funding rounds
| Date | Stage | Investors | Raised | Deal Summary |
|---|---|---|---|---|
| Apr 2022 | Undisclosed stage | Oracle (lead) | $128M | Ampere Computing is a semiconductor design company specializing in high-performance, energy-efficient Arm-based processors for data centers and cloud computing, targeting competition with Intel and AMD in server chips. Founded in 2017 by Renée James, a former Intel executive, Ampere received investments from Oracle, including a $300 million round in 2021 solely backed by Oracle, bringing total Oracle backing to $400 million by April 2022. Oracle's stake grew to 29% by May 2024, with options for control, but shifted strategy led to selling its position for a $2.7 billion pre-tax gain following SoftBank's acquisition. Ampere's Altra CPUs powered virtual machines in Oracle Cloud and Microsoft Azure (in preview by 2022), capturing less than 1% of the server market but gaining traction with hyperscalers seeking cost-effective Arm alternatives. The company explored paths like IPO, acquisition by Arm, or further investment but faced challenges, with total funding around $800 million by 2022. In March 2025, SoftBank announced acquisition of Ampere, completed November 25, 2025, making it a wholly owned subsidiary to bolster AI infrastructure like the Stargate Project. Oracle later deemed its stake non-strategic, favoring in-house chip design. |
| Apr 2022 | Secondary | Oracle (lead) | $128M | Ampere Computing designs high-performance, energy-efficient processors specialized for next-generation cloud computing and AI workloads based on the ARM compute platform. The company reported revenue of $151.822 million for the financial year ended December 2022, alongside an operating loss of $518.290 million and net loss of $513.815 million. It had total assets of $517.800 million and negative net assets of $264.915 million at that time. Ampere had raised around $800-814 million in prior funding by April 2022, with investors including Oracle and Carlyle Group. Oracle held a significant stake, later reaching 29% by May 2024. Later, SoftBank acquired Ampere for $6.5 billion in March 2025, with Oracle and Carlyle selling their stakes. |
| Mar 2021 | Strategic investment | Oracle (lead) | $300M | - |
| Sep 2019 | Strategic investment | Oracle (lead) | $40M | Ampere Computing develops 64-bit Arm server-class processors for cloud and edge servers, emphasizing performance and energy efficiency. Oracle invested $40 million in April 2019, acquiring less than 20 percent of the company's outstanding shares, with the investment disclosed in September 2019 due to Ampere CEO Renée James serving on Oracle's board. Oracle also appointed a board member to Ampere's board and paid about $419,000 for development and testing hardware in fiscal 2019. Ampere had previously received investments from SoftBank's Arm Holdings and The Carlyle Group, though details were not publicized at the time. The company, led by former Intel executive Renée James, positions its processors as alternatives to x86 architectures, with Oracle Linux supporting 64-bit Arm processors. This investment occurred amid Oracle's strategic shifts, including downsizing its low-margin SPARC hardware business and focusing on cloud services. Later developments include Oracle's additional investments and prepayments totaling over $400 million in subsequent years, Arm holding a 6.8 percent stake valued at $389.8 million as of March (recent fiscal year), and Ampere filing for an IPO with launches like the AmpereOne processor family. |
