SK Hynix Juggles Construction Strike and $14 Billion US Listing as AI Boom Fuels Rally

SK Hynix shares rally 200%+ in 2024, but a concrete-truck driver strike halts construction at its Yongin megafactory, threatening AI-driven capacity expansion and its planned $14B US listing.

The sizzling rally in SK Hynix shares — up more than 200% this year — tells only half the story. Behind the scenes, a strike by 8,000 concrete-truck drivers in the greater Seoul area has brought work at the chipmaker's Yongin megafactory to a standstill, even as the company prepares to raise up to $14 billion through a US listing to fund new plants in Korea and Indiana.

The walkout, now in its second week after the union rejected an initial pay offer from concrete producers on Wednesday, has halted construction at over 100 major sites nationwide. At SK Hynix’s Yongin campus, all concrete pouring has stopped. Rival Samsung has also suspended work at its Pyeongtaek complex. The management says it has rearranged workflows to limit the immediate damage, but warns that a prolonged blockade could delay the capacity additions needed to meet surging AI-driven demand.

That demand shows no signs of cooling. South Korea’s semiconductor exports tripled in the first ten days of June to $11 billion compared with the same period a year earlier, underscoring the global appetite for the high-bandwidth memory chips that SK Hynix supplies to Nvidia under a recently sealed technology partnership. The stock has ridden that wave: on Friday it rose 2.33% to 2,150,000 Won, bringing its year-to-date gain to nearly 218%. Just a day earlier it closed at 2,101,000 Won after having climbed 233.09% in 2024, highlighting the wild swings that have become the norm. The annualized 30-day volatility stands at a staggering 103.26%, and the shares now trade 43% above their 50-day moving average.

To finance its next wave of expansion, SK Hynix is turning to Wall Street. The company plans to list American Depositary Receipts representing 2% to 3% of its total shares, with the main Seoul listing remaining in place. Proceeds from the up-to-$14 billion offering will bankroll new fabrication plants in South Korea and in Indiana. The US Securities and Exchange Commission is reviewing the application and could give the green light as early as the week of June 22, setting the stage for the ADRs to begin trading in August.

The timing of the US listing is no accident. American investors have piled into AI beneficiaries, and SK Hynix’s close ties to Nvidia make it a natural candidate for fresh capital. Yet the construction strike adds a layer of uncertainty: if the walkout drags on, the timeline for new capacity will slip, capping the company’s revenue potential just as it seeks to justify the premium valuation implied by its US debut.

For now, the market is betting that existing production lines will keep running and that the strike will prove a temporary hiccup. But with the union digging in and no new talks scheduled, the next few weeks will test whether the AI-driven rally can withstand a concrete shortage on the factory floor.
