SK Hynix's Two-Front Battle: A Labor Revolt Over Stock Bonuses Meets a $38 Billion Capacity Bet
Published on 08/10/2026 at 12:03 | Redaktion boerse-global.de
The numbers coming out of SK Hynix are, by any measure, extraordinary. Second-quarter revenue hit 79.32 trillion won — a 257 percent surge year over year — while operating profit exploded 557 percent to 60.54 trillion won, pushing the operating margin to a record 76 percent. Yet the stock tells a different story: after a 120.10 percent run since January, the shares have surrendered 34.86 percent of their value in just 30 days, trading at 1,420,000 won as of Monday.
That disconnect between operational brilliance and market punishment has created an unusual moment for the Korean chipmaker. Management is simultaneously fighting a nascent labor rebellion over compensation, fending off a resurgent Samsung Electronics in the HBM arena, and trying to convince investors that a massive capacity expansion is worth the near-term pain.
The labor dispute escalated Monday when roughly 3,800 employees — about 11 percent of the workforce — filed paperwork to establish a unified, company-wide union, according to the Korea Herald. The trigger: management's plan to shift a portion of performance bonuses into locked-up company shares rather than cash. The move lands at a delicate moment, with the Relative Strength Index at 39.0 signaling the stock is approaching oversold territory.
A Rebound Attempt and a Bullish Call
Tuesday brought some relief. The shares climbed 0.56 percent to 1,430,000 won, riding a broader rally in Seoul's tech sector and a notable analyst endorsement. Morgan Stanley's Sean Kim — the strategist who famously warned of a "Memory, Winter Is Coming" scenario in 2021 — declared the correction in memory chip stocks over. The bank reaffirmed its 2.6 million won price target and raised its 2026 earnings estimate for SK Hynix by 13 percent, recommending investors re-enter the trade.
Should investors sell immediately? Or is it worth buying SK Hynix?
Kim's conviction rests partly on the fading of foreign selling pressure. After outflows of roughly 30 billion dollars in June and 6.2 billion dollars in July, August has seen just 4.3 billion dollars leave so far — a trajectory that suggests the worst of the exodus may be behind. Notably, Morgan Stanley took the opposite stance on Samsung Electronics, cutting its earnings estimate there by 10 percent while holding the price target at 375,000 won.
The analyst enthusiasm isn't universal, though. Barclays trimmed its price target from 330 to 300 dollars on July 30, though it kept an Overweight rating. Then came a flurry of fresh coverage on August 4: Bank of America resumed coverage with a Buy and a 250-dollar target, citing long-term AI chip orders from US tech giants, while Wolfe Research, RBC Capital, Cantor Fitzgerald, Rosenblatt, and Needham all initiated with Buy ratings and targets ranging from 200 to 320 dollars. Those assessments apply to the American Depositary Receipts trading on the Nasdaq under the ticker SKHY since July 10.
The $38 Billion Question
The primary driver of the recent sell-off, however, was the company's own board. On August 7, SK Hynix approved a 54.3 trillion won investment package — roughly 38.3 billion dollars — for two new fabrication facilities. The Yongin "Y2" plant will absorb 35.2 trillion won for HBM and DRAM production, with construction slated to begin in July 2027 and the first clean room expected by June 2029. The Cheongju "M17" NAND facility, funded with 19.1 trillion won, is scheduled for a February 2027 groundbreaking and December 2028 clean-room completion.
Market research firm Omdia projects the expansion will support annual growth of around 19 percent in both DRAM and NAND through 2030. But investors initially balked at the sheer scale of the commitment, prompting the company to promise additional shareholder returns in the third quarter of 2026. Management has also signaled it will review and expand its capital allocation program, with concrete details expected in Q3 2026 — a response to investor dissatisfaction with the previous guidance.
The investment push comes alongside product innovation. At the Future of Memory and Storage conference, SK Hynix unveiled its tenth-generation NAND flash — a 375-layer chip the company claims delivers 2.5 times better energy efficiency. Together with Sandisk, it also published initial technical specifications through the Open Compute Project for High Bandwidth Flash, a memory architecture designed to address bottlenecks in AI inference workloads. The board additionally approved a quarterly dividend of 375 won per share for Q2 2026.
The Labor Question and the Suwon Threat
The bonus dispute carries real operational risk. SK Hynix and its union have completed five rounds of negotiations without reaching an agreement on the stock-based bonus plan, and more than 3,500 employees — around ten percent of the workforce — have signaled their intent to form a separate union. The standoff threatens to delay the ramp-up of HBM4 chips, which began volume shipments in the second quarter and were slated for expansion in the second half of the year.
SK Hynix at a turning point? This analysis reveals what investors need to know now.
Meanwhile, the competitive picture is shifting. Samsung Electronics claims it has achieved roughly 80 percent yield on HBM4 — four months ahead of schedule — with HBM4E yield exceeding 70 percent in reliability testing. UBS projects Samsung will capture a 41 percent share of the HBM market next year, edging out SK Hynix's expected 39 percent.
Chairman Chey Tae-won has already put his money where his mouth is, purchasing 4.5 billion won worth of SK Hynix shares on the open market in late July following the post-earnings volatility. The company is also exploring strategic options for its packaging and testing facility in Chongqing, with Bloomberg reporting a potential stake sale that could value the plant at around three billion dollars — a portfolio adjustment that fits a company simultaneously deploying billions into new capacity while reorganizing its overseas footprint.
For investors, the calculus is brutally simple. The fundamentals are the strongest in the company's history, the strategic position in AI memory is enviable, and the product pipeline is full. But between a restive workforce, a resurgent rival in Suwon, and a capital expenditure program that demands patience, the market's verdict on SK Hynix remains very much in play.
