Sources: Allen Wu, who was replaced as CEO of Arm China by Liu Renchen, has refused to surrender control amid Shanghai's lockdown, where Arm China's HQ is based
Allen Wu refuses to surrender control in extraordinary corporate battle at UK chip designer — High in a Shenzhen office tower …
Context & Ripple Effects
This standoff is the second act of a fight that began in June 2020, when Arm said it had replaced Allen Wu after discovering he had set up a competing investment fund — an ouster Wu simply refused to accept, publicly contradicting his own parent company (fired for a rival fund). For nearly two years he kept operating Arm China from its Shanghai headquarters while Arm and SoftBank worked on a legal path back.
The new wrinkle: sources say SoftBank and Arm were close to an agreement to regain control just before this report, but Shanghai's lockdown has physically frozen the handover to named successor Liu Renchen. Control of the JV matters because Arm China licenses Arm's designs into the world's largest smartphone-chip market.
First-order effects
- Liu Renchen holds the CEO title on paper, but Wu still commands the Shanghai headquarters and its staff, so Arm China effectively has two managements and no single point of authority for licensees.
- Shanghai's lockdown gives Wu a practical shield: any attempt by Arm or SoftBank to execute the handover in person is blocked while the city is sealed.
Second-order effects
- Every quarter the dispute drags on, Arm's royalty stream from Chinese licensees sits behind contested sign-offs, pressuring SoftBank to escalate from negotiation to legal or shareholder-level action.
- Chinese partners and licensees must hedge between the two claimants, and Beijing's tolerance for a foreign firm losing control of its own JV becomes part of the bargaining table.
Third-order effects
- If the pattern holds, the endgame is a leadership reset rather than a return to the old order — which is what eventually happened when Arm China installed ex-Rockchip executive Chen Feng as CEO and the co-CEOs resigned (Chen Feng named CEO in 2025).
- Structurally, the episode shows that Western chip firms' Chinese joint ventures can be captured by their own local management, making JV governance a market-access risk that boards now price into China strategy.
The trend: Control of Western semiconductor firms' Chinese joint ventures is becoming a governance battleground where local management, not the foreign parent, holds the operational leverage.
