私募股权基金贝恩资本已于今年7月初彻底清仓日本存储芯片企业铠侠的全部股份[1]。此次清仓交易实现了约170亿美元（约合人民币1151亿元）的收益，回报率接近初始投资的20倍[1]。贝恩资本首席合伙人David Gross表示："我们不再持有任何铠侠股份"[1]。
贝恩资本于2018年以180亿美元收购东芝存储约55%的股份[1]。在持股期间，贝恩资本的股份比例曾从2025年12月的约44%逐步降至约14%，最终在今年7月初完成全部清仓[1]。此次退出恰逢铠侠股价大幅上涨，该公司股价一度猛涨接近50倍，今年6月中旬市值曾达56万亿日元（约合3450亿美元），一度超越丰田汽车[1]。
铠侠经历了多年的IPO筹备过程，其上市计划在2020、2021、2022、2024年间四度流产，直到2024年年底才最终登陆东京证券交易所[1]。
Bain Capital has fully divested its stake in Kioxia, the Japanese storage chip manufacturer, by early July 2025, realizing approximately $17 billion in proceeds on its initial investment [1]. The private equity firm's exit represents a return of roughly 20 times the original capital deployed, marking a landmark success in global PE history [1].
Bain Capital acquired approximately 55% of Toshiba's storage business in 2018 for $18 billion, with Bain itself investing over $1 billion into the deal [1]. The firm's shareholding had declined from approximately 44% in December 2024 to about 14% before the complete liquidation in early July [1]. David Gross, representing Bain Capital, stated at that time: "We no longer hold any Kioxia shares" [1].
The investment's success coincided with surging demand for storage capacity driven by the artificial intelligence computing boom [1]. Kioxia's stock price surged nearly 50-fold at its peak, with the company's market capitalization reaching 56 trillion yen (approximately $345 billion) in mid-June 2025, temporarily exceeding that of Toyota Motor [1]. The company had pursued an initial public offering four times—in 2020, 2021, 2022, and 2024—before finally listing on the Tokyo Stock Exchange in late 2024 [1].
