Taiwan Semiconductor Manufacturing Company (TSMC) completes its divestment from Arm, signaling a portfolio reshuffle amid semiconductor market volatility.
Taiwan Semiconductor Manufacturing Company has sold its remaining stake in Arm Holdings plc for about $231 million, completing its exit from the British chip designer, according to a regulatory filing.
The transaction was carried out by TSMC’s subsidiary, TSMC Partners Ltd., which disposed of 1.11 million Arm shares between April 28 and April 29 at an average price of $207.65 per share, the company disclosed in a material information filing on Taiwan’s Market Observation Post System (MOPS).
Following the sale, TSMC no longer holds any shares in Arm, bringing to an end an investment that began with Arm’s return to public markets in 2023. The disposal resulted in an approximately $174 million impact on retained earnings, the filing showed.
TSMC described the move as the disposal of an equity investment, indicating the transaction was part of portfolio management rather than a shift in operational strategy. The company had gradually reduced its holding over the past year, including an earlier sale of Arm shares in 2024 as part of a multi-stage divestment process.
The exit comes amid heightened volatility in semiconductor and artificial-intelligence related stocks, with Arm shares experiencing recent market pressure following broader investor reassessment of AI-linked valuations. Despite the divestment, both companies remain closely connected within the global semiconductor ecosystem, where Arm provides processor architectures used across smartphones, data-centre infrastructure, and emerging AI systems, while TSMC manufactures advanced chips for leading technology firms worldwide.
The completed sale highlights how strategic investors are increasingly reassessing financial holdings while maintaining core industry partnerships in an evolving semiconductor market.
