SK Hynix has become Kioxia's largest shareholder with a 14.19 percent stake, surpassing Toshiba's 14.06 percent after seven consecutive share sales.
Kioxia flagged SK Hynix's convertible bond rights in its annual report as a "risk factor with potential conflicts of interest," according to disclosures cited by Bloomberg and Nikkei on August 11.
Toshiba executed seven on-market sales of Kioxia shares from mid-July through August 3, reducing its holdings from roughly 82.47 million shares to 77.03 million shares and lowering its stake from 15.10 percent to 14.06 percent. BCPE Pangea Cayman2 (SPC2), the investment vehicle SK Hynix funded with approximately 1.3 trillion won ($919.6 million) in convertible bonds, maintained its position of roughly 77.4 million shares, edging past Toshiba by about 360,000 shares.
SK Hynix's path to the top shareholder position traces to 2018, when it joined a Bain Capital-led consortium to acquire Toshiba's memory business for about 4 trillion won ($2.8 billion). The stake gives SK Hynix indirect influence over Kioxia, the world's third-largest NAND flash memory maker behind Samsung Electronics and SK Hynix itself. However, converting the bonds into voting shares would require clearing merger control reviews in South Korea, the United States, Japan, and other jurisdictions, with Japanese government scrutiny seen as the biggest hurdle.
SK Hynix committed in 2018 to keeping its voting stake below 15 percent through 2028 unless Kioxia permitted a higher threshold. The company's other investment vehicle, SPC1, was fully divested in June when Bain Capital exited its investment, leaving SPC2 as the sole channel for SK Hynix's Kioxia holdings.
The ownership shift carries strategic weight in the NAND market. Kioxia pioneered NAND flash memory and ranks third globally behind Samsung and SK Hynix, which includes its Solidigm subsidiary. According to reports from Bloomberg and Nikkei, SK Hynix could gain a favorable competitive position in any future NAND market restructuring, including potential mergers and acquisitions.
Inside SK Hynix, deliberations are reportedly ongoing over how to use the SPC2 stake. Even without immediate voting rights, the position serves as a strategic tool to keep Kioxia in check and as a valuable investment asset. The prevailing industry view is that SK Hynix will hold onto the convertible bonds while monitoring market conditions and the evolving regulatory environment.
The stake's strategic value will hinge on whether CB conversion proceeds and how Japanese and other regulators respond. Any regulatory decision on the convertible bond structure would determine whether this financial investment deepens into operational influence over a key NAND competitor, with the next milestone being any antitrust filing or regulatory review announcement.
