South Korean tech giant SK hynix (OTCPK:HXSCF) said first quarter revenues and operating profit achieved the second-highest quarterly records, while operating margin improved for eight consecutive quarters.

SK Hynix's quarterly profit more than doubled on strong AI chip sales and stockpiling ahead of potential U.S. tariffs, but it warned that macroeconomic uncertainties could create demand volatility in the second half of the year.
