China's market regulator has imposed fines on Luxshare and Wingtech for their deal unwinding.

      SAMR has imposed penalties on two electronics companies due to procedural breaches related to their now-failed asset sale, marking another indication of Beijing's stricter approach to merger enforcement. The State Administration for Market Regulation in China has fined Luxshare Precision Industry and Wingtech Technology for violations linked to their collapsing asset transaction, as reported by Reuters on Wednesday.

      This fine represents the latest formal action in a deal that has evolved over the past 18 months from a pressured divestment to a Singapore arbitration dispute, illustrating how vulnerable Chinese electronics firms are to intertwining commercial, geopolitical, and regulatory challenges. The deal in question involved Wingtech’s sale of its product-assembly business to Luxshare, which was agreed upon in early 2025 for approximately 4.4–4.6 billion yuan ($630 million). Wingtech, a supplier for iPhone and parent company of Nexperia, was compelled to sell due to losses from US sanctions that rendered its assembly operations commercially unviable. Luxshare, a competitor to Foxconn and a significant Apple supplier, agreed to take over the assembly assets, including the operations in India.

      Almost immediately, the deal began to fall apart. Indian authorities confiscated the local manufacturing assets on national-security grounds, expressing concerns about Chinese ownership of key electronics-manufacturing capabilities. Luxshare initially paid about 2 billion rupees ($22 million) but was unable to finalize the transfer.

      In January 2026, Luxshare sought arbitration at the Singapore International Arbitration Centre to reverse the Indian aspect of the deal and recover its deposit. Wingtech filed a counterclaim, asserting that Luxshare's attempt to terminate the agreement constitutes a breach.

      According to Reuters, SAMR's fine focuses on the procedural integrity of the deal rather than its competitive implications. The recently amended Anti-Monopoly Law in China provides the regulator with significantly enhanced authority to penalize notification failures, "gun-jumping," and other merger-control violations, with fines potentially reaching up to 10% of the infringing party’s revenue from the previous year.

      The 2024 amendments to the law also lowered the procedural requirements for SAMR to intervene in transactions that do not meet formal notification thresholds but are still considered significant by the regulator.

      The overall landscape is challenging, as SAMR has demonstrated a clear tightening of its merger-enforcement stance over the past 18 months, notably increasing the number of gun-jumping cases and adopting a more assertive interpretation of which transactions necessitate pre-completion notification.

      The fine imposed on Luxshare and Wingtech follows this pattern and serves as a warning to other Chinese electronics companies facing US sanctions that any attempts at forced divestment will not be automatically approved under the premise that geopolitical factors warrant relaxed regulatory oversight.

      For Luxshare, this fine comes at an inconvenient time. The company has been heavily investing to expand its AirPods and broader Apple-supplier operations, and any suggestion of inconsistent M&A behavior complicates its relationship with Apple. Meanwhile, Wingtech has been transitioning towards semiconductors over the past year after divesting its assembly business, facing its own financial strain due to the same US sanctions that initiated the divestment.

      At the time of the Reuters report, neither company commented on the specific amount of the SAMR penalty. The arbitration proceedings in Singapore are still ongoing, with a procedural hearing reportedly set for later this quarter.
