SK Hynix's Order Book Tells a Different Story Than Its Share Price

SK Hynix shares slip on rate and tariff jitters, but record Q2 results, 58% HBM share, and $750B orders suggest a disconnect.

The disconnect between SK Hynix's operational trajectory and its recent stock performance is becoming hard to ignore. Shares of the South Korean memory chip giant have slipped roughly 7.7 percent over the past week, with the stock changing hands at 1,596,000 won after closing at 1,613,000 won the previous session. Yet the forces behind that decline appear to have little to do with the company's underlying business — and a growing chorus of Wall Street voices is starting to say so.

Rate Jitters and Tariff Rhetoric Weigh on the Sector

The immediate trigger for the selloff came from across the Pacific. Yields on ten-year US Treasuries climbed to 4.82 percent, their highest level since November 2023, while the 30-year yield touched 5.27 percent — a peak not seen since June 2007. Growth stocks bore the brunt, with semiconductor names hit particularly hard. Adding to the pressure, US Commerce Secretary Howard Lutnick signaled plans for targeted tariffs on imported chips, explicitly naming Samsung and SK Hynix while suggesting relief for companies with US manufacturing footprints. Both Korean giants are already investing stateside: Samsung has committed more than $37 billion to its Texas operations, while SK Hynix is pouring $4 billion into an Indiana facility.

The irony is that these macro anxieties are colliding with demand figures that border on the extraordinary. South Korea's semiconductor exports surged 209 percent year-on-year in August to a record $46.65 billion — nearly half of the country's total export volume. That is not a picture of softening demand; it is one of accelerating scarcity.

A Backlog That Speaks Volumes

Against that backdrop, the company's order book looks almost surreal. Reports indicate SK Hynix has secured customer contracts worth $750 billion, including $500 billion from Nvidia alone. In the high-bandwidth memory (HBM) segment — the most profitable corner of the memory market — the company commanded a 58 percent share in the first quarter of 2026, leaving Samsung and Micron trailing at 21 percent each.

Susquehanna analysts anticipate DRAM price increases of up to 50 percent and NAND price gains reaching 60 percent. For a manufacturer holding leadership in the industry's fastest-growing premium segment, that pricing environment translates into formidable earnings momentum.

Bernstein has taken notice. The firm initiated coverage on Tuesday with a buy recommendation, pointing to a second quarter that saw revenue hit 79.3 trillion won — up 257 percent from a year earlier — and operating profit reach 60.5 trillion won, both all-time records. The operating margin came in at 76 percent, fueled by DRAM prices rising roughly 30 percent and NAND climbing into the mid-teens to low-fifties percentage range.

HBM4 Ramp and a Strengthened Balance Sheet

The second quarter also marked the start of mass production for HBM4, the latest generation of high-bandwidth memory designed for AI accelerators. Management expects a broader production ramp in the second half of the year and has already inked long-term supply agreements with around ten customers. For the third quarter, the company projects DRAM shipments to rise about 10 percent sequentially, with NAND growing only in the low single digits.

That momentum has prompted a wave of positive revisions. S&P Global Ratings upgraded SK Hynix's credit rating from BBB+ to A- in mid-August, citing the AI-driven business trajectory and attaching a positive outlook. Needham followed suit later that month, lifting its price target from $200 to $220 while reaffirming its buy rating.

The balance sheet supports the optimism. With net cash of roughly 69 trillion won at the end of the second quarter, SK Hynix has ample firepower — and it is putting that capital to work. The board approved a 40 trillion won share buyback program in mid-August, complete with full cancellation of the repurchased shares, and raised its payout target from "up to 50 percent" to "over 50 percent" of cumulative free cash flow. The buyback is slated to run over approximately three months.

Capital expenditure plans are equally ambitious, with 2026 investments expected in the high range of 40 trillion won to accelerate production at the M15X facility. The groundbreaking for the $4 billion HBM packaging plant in Indiana, which took place just over a week ago, fits neatly into that expansion strategy.

Labor Friction and a Possible Japan Play

Not everything is running smoothly. Workers rejected a preliminary wage agreement offering a 6.3 percent increase, prompting CEO Kwak Nojeong to launch a company-wide communications push and signal willingness to renegotiate. The dispute has added a layer of overhang to the stock, though it reads more as a distributional squabble than a strategic threat given the strength of the order pipeline.

Meanwhile, SK Group Chairman Chey Tae-won told the Asahi Shimbun that the company is exploring a new memory chip plant in Japan, potentially in partnership with Kioxia — a company in which SK Hynix already holds the largest stake through convertible bonds. A decision could come before year-end. That optionality is unlikely to move the stock on its own, but it underscores management's focus on adding capacity at a time when industry estimates suggest demand for data-center memory chips is running 20 to 30 percent ahead of supply.

The Gap Between Price and Fundamentals

The stock showed tentative signs of stabilization on Thursday, gaining 1.2 percent to 1,633,000 won, though it remains below recent levels. The next earnings release is scheduled for October 27, when investors will get a clearer read on whether the HBM4 ramp is meeting the elevated expectations now baked into analyst models.

For the moment, the arithmetic is straightforward: a company with record exports, a 58 percent HBM market share, $750 billion in secured customer contracts and a credit upgrade in hand is trading lower primarily because of external rate movements and tariff rhetoric. That looks less like a deteriorating business and more like a valuation recalibration — one that Bernstein and others are betting will eventually correct itself.
