[Edaily Reporter An Yu-ri ] SK hynix(000660) shares closed up more than 3% on the Nextrade (NXT) after-hours market on the 23rd compared to the previous day. After rising more than 4% during regular trading hours, the gain narrowed slightly but the stock maintained its upward trend. In contrast, SamsungElectronics(005930)shares, which had closed higher during regular trading, fell slightly in after-hours trading.

Based on the NXT after-market closing price on the 23rd, SK hynix closed at 1,263,000 won, up 40,000 won (3.27%) from the previous trading day. While this is 14,000 won lower than the regular session closing price of 1,277,000 won, the stock still posted a gain in the 3% range compared to the previous trading day’s close.

Earlier that day, SK hynix also closed at 1,277,000 won during regular trading hours, up 54,000 won (4.42%) from the previous trading day.

SamsungElectronics traded at 213,500 won on the NXT after-hours market, down 1,000 won (0.47%) from the previous trading day. Although it closed at 215,500 won during regular trading—up 1,000 won (0.47%) from the previous day—it turned lower in after-hours trading.

Meanwhile, the KOSPI overcame early weakness to close higher that day. Although it fell nearly 4% early in the session, a rebound in large-cap semiconductor stocks helped recoup the losses. The KOSPI closed at 5,550.30, up 16.53 points (0.30%) from the previous trading day.

The rise in SK hynix’s stock price is believed to have been influenced by news that Solidigm has suspended its consideration of a U.S. IPO. Solidigm is a U.S.-based subsidiary of SK hynix, established in 2021 after SK hynix acquired Intel’s NAND flash and solid-state drive (SSD) businesses.

Market observers had pointed out that if Solidigm were to list separately, concerns over dual listings and the potential for share dilution could weigh on the value for existing shareholders. The interpretation is that these concerns have been partially alleviated now that SK hynix has halted its plans to pursue a Solidigm IPO.

SK hynix stated in a regulatory filing released today, “Our overseas subsidiary, Solidigm, has been reviewing various financing options to expand production capacity and strengthen competitiveness; however, after comprehensively considering capital market conditions and other factors, we have decided to discontinue our review of pre-IPO funding and an initial public offering (IPO).”
