Softbank Group Corp’s Arm Ltd and its Chinese chip venture yesterday clashed publicly over whether the venture’s chief executive officer had been fired, a dispute that threatens to disrupt a company central to the global semiconductor industry.
The British firm on Tuesday said that the board of Arm China (安謀中國) — jointly owned by Arm and investors including China’s sovereign wealth fund — voted to remove chief executive officer Allen Wu (吳雄昂) and replace him with a pair of co-CEOs.
Hours later, Arm China posted a statement on its WeChat (微博) account asserting that Wu was still in charge and the venture was operating normally.
The British firm then fired back to say it stood by its original statement, adding that Wu had been fired after an investigation uncovered undisclosed conflicts of interest and contraventions of employee rules.
“Following a whistle-blower complaint, and several other current and former employee complaints, an investigation was undertaken by Arm Limited,” the company said in its latest statement, jointly issued with shareholder Hopu Investment Management (厚朴基金管理).
“Evidence received from multiple sources found serious irregularities, including failing to disclose conflicts of interest and violations of the employee handbook,” it said.
The controversy came at a sensitive time for Arm and the company’s 49 percent-owned Chinese affiliate, when Western firms are struggling to navigate an escalating clash between the US and China over technology leadership.
Arm, a UK-based company whose semiconductor designs are used in a majority of the world’s mobile devices, is among the firms grappling with the uncertainty of growing tensions.
Arm said that the board had appointed Ken Phua (潘鎮元) and Phil Tang (唐效麒) as Arm China’s interim co-CEOs.
Wu did not respond to e-mails and a message sent via his LinkedIn profile seeking comment.
Arm China yesterday on WeChat said that the executive remained in charge.
“In accordance with relevant laws and regulations, Allen Wu continues to serve as chairman and CEO,” the post read.
Softbank in 2016 acquired Arm for US$32 billion in one of its largest acquisitions, a deal intended to further Softbank founder Masayoshi Son’s ambition of creating a global Internet of Things ecosystem.
Arm China was formed in 2018, when Softbank sold 51 percent of the subsidiary to a consortium that included China Investment Corp (中國投資), the Silk Road Fund and Singaporean state investment firm Temasek Holdings Pte.
It operates offices in Shenzhen, Beijing and Shanghai, and acts as an intermediary between Arm in the UK and clients, such as Huawei Technologies Co (華為), in the world’s largest smartphone market.
Arm licenses the fundamentals of chips for companies that make their own semiconductors and also sells processor designs.
Most of the world’s smartphones depend on Arm’s technology, and it is trying to expand into servers and PCs.
The company has been ensnared in Washington’s campaign against Huawei because of its central role in semiconductor architecture.
That conflict escalated after Washington last year prohibited the sale of US software and circuitry to Huawei, a key Arm client.
The British company has said it would comply with the so-called US Entity List restrictions.
Local media have cited Wu as saying his company would continue to work with Huawei.
Arm continues to supply technology to Huawei unit HiSilicon Technologies Co (海思半導體), but it is unclear if it can license future designs to the Chinese company.
NEW IDENTITY: Known for its software, India has expanded into hardware, with its semiconductor industry growing from US$38bn in 2023 to US$45bn to US$50bn India on Saturday inaugurated its first semiconductor assembly and test facility, a milestone in the government’s push to reduce dependence on foreign chipmakers and stake a claim in a sector dominated by China. Indian Prime Minister Narendra Modi opened US firm Micron Technology Inc’s semiconductor assembly, test and packaging unit in his home state of Gujarat, hailing the “dawn of a new era” for India’s technology ambitions. “When young Indians look back in the future, they will see this decade as the turning point in our tech future,” Modi told the event, which was broadcast on his YouTube channel. The plant would convert
Nanya Technology Corp (南亞科技) yesterday said the DRAM supply crunch could extend through 2028, as the artificial intelligence (AI) boom has led the world’s major memory makers to dramatically reduce production of standard DRAM and allocate a significant portion of their capacity for high-bandwidth memory (HBM) chips. The most severe supply constraints would stretch to the first half of next year due to “very limited” increases in new DRAM capacity worldwide, Nanya Technology president Lee Pei-ing (李培瑛) told a news briefing. The company plans to increase monthly 12-inch wafer capacity to 20,000 in the first half of 2028 after a
Property transactions in the nation’s six special municipalities plunged last month, as a lengthy Lunar New Year holiday combined with ongoing credit tightening dampened housing market activity, data compiled by local land administration offices released on Monday showed. The six cities recorded a total of 10,480 property transfers last month, down 42.5 percent from January and marking the second-lowest monthly level on record, the data showed. “The sharp drop largely reflected seasonal factors and tighter credit conditions,” Evertrust Rehouse Co (永慶房屋) deputy research manager Chen Chin-ping (陳金萍) said. The nine-day Lunar New Year holiday fell in February this year, reducing
Zimbabwe’s ban on raw lithium exports is forcing Chinese miners to rethink their strategy, speeding up plans to process the metal locally instead of shipping it to China’s vast rechargeable battery industry. The country is Africa’s largest lithium producer and has one of the world’s largest reserves, according to the US Geological Survey (USGS). Zimbabwe already banned the export of lithium ore in 2022 and last year announced it would halt exports of lithium concentrates from January next year. However, on Wednesday it imposed the ban with immediate effect, leaving unclear what the lithium mining sector would do in the
