A Bain Capital vehicle holding 14.19% of Kioxia has become the flash maker’s top shareholder, and Kioxia’s annual report warns the arrangement could create a conflict of interest.
The vehicle, BCPE Pangea Cayman2, controls voting rights that SK Hynix could largely take over through convertible bonds, the Japanese company disclosed.
Former parent Toshiba trimmed its stake to 14.12% from 14.48% as of Aug 3, Kioxia said on Aug 11, ceding the top spot to the Bain entity.
SK Hynix joined the Bain-led consortium that acquired Kioxia in 2018 and committed to keeping its voting rights at or below 15% until 2028 unless Kioxia consented.
The warning lands as NAND prices climb on AI demand and Kioxia shares outperform the market.
SK Hynix, which also owns Solidigm, keeps consolidating its grip on the memory industry, and sway over a rival’s largest investor raises governance questions neither company has answered.
The disclosure confirms that the balance of power inside Japan’s flash memory champion has quietly shifted toward its South Korean competitor.
