Arm China, had said it has replaced its CEO Allen Wu with interim co-CEOs Ken Phua and Phil Tang.
SoftBank had acquired ARM in 2016 for $32 billion
The Chinese joint venture of SoftBank Group Corp-owned ARM rejected on Thursday allegations of misconduct made by its investors against its CEO and said it would take legal action, escalating an internal spat.
The internal conflict at one of the global chip industry's major suppliers spilled into the open on Wednesday after ARM and its China joint venture publicly disagreed whether the unit's CEO, Allen Wu, had been fired.
British-based ARM and Chinese private equity firm Hopu Investments, which co-own Arm China, had said they replaced Wu with interim co-CEOs Ken Phua and Phil Tang after an investigation found serious irregularities with Wu's conduct.
ARM China said on Thursday the allegations had negatively affected Wu and the firm, and that it had entrusted lawyers to look into the matter. It had said Wu continues to be its CEO.
It said a board meeting by ARM and Hopu Investments held on June 4 to dismiss Wu had not followed procedure and thus could not "trigger a personnel change". It added that Tang had been dismissed from the joint venture on May 26 due to "serious violations" and no longer represented the company.
A spokeswoman for ARM told Reuters that they stood by their previous statements.
"ARM China's relevant operations are carrying on as normal," the joint venture said.
Reuters could not immediately reach Phil Tang through ARM for comment.
Arm China, which generates revenue by licensing chip architecture to Chinese companies, was established in 2018 when SoftBank sold a 51 percent stake in ARM's Chinese subsidiary, ARM Technology (China), to a group of Chinese investors. SoftBank had acquired ARM in 2016 for $32 billion (roughly Rs. 2.41 lakh crores).
The spat comes as ARM grapples with rising tensions between the United States and China over technology. Last month, the Department of Commerce placed additional restrictions on smartphone maker Huawei that would prevent certain US companies from supplying to it.
