SK Hynix Delays HBM4 Equipment Orders as Its Stock Falls 5 Days Straight

SK hynix (NASDAQ:SKHY) trades at $157.06, against an average analyst price target of $252.21, an implied upside of about 60.6%.

A gap above 40% suggests analysts and the market sharply disagree about where memory is heading. SK hynix leads in high-bandwidth memory (HBM), the stacked DRAM placed beside AI accelerators. That position supports an operating margin of 48.59%.

The newest pressure arrived overnight. A Korean outlet reported that some of SK hynix’s HBM4 back-end equipment orders, planned for the second half of this year, may slip into next year. The report names no suppliers or amounts, and the company has not commented.

HBM4 is the next generation of that memory, and back-end work covers packaging and testing. A delay rooted in technical trouble would justify the discount, while one rooted in shifting priorities would make the analyst targets look more credible.

Seven Straight Losses in New York and Six in Seoul

The US-listed shares fell 3.19% in the latest session. That was their seventh straight lower close, and they slipped another 0.76% after hours to $155.87.

In Seoul, a 10.09% drop completed a fifth straight decline. A further 1.73% fall to 1,418,000 won made it six, leaving the shares about 23% below their early-October close of 1,841,000 won.

The US listing is down about 19.5% from its early-October close of $195.13, which sat near the 52-week high of $199.87. It remains above the $124.80 low. Over the past week, it lost 13.97%, while the S&P 500 slipped 0.14%. The index is up 14.09% this year.

The damage hit the whole sector. Samsung and SK hynix led a chip selloff on fears of Chinese competition, and Micron Technology (NASDAQ:MU | MU Price Prediction) fell 8.83% over the same week.

Why Late Packaging Tools Would Mean Late HBM4 Revenue

Equipment orders are the first visible sign of a capacity plan. If back-end tools arrive late, HBM4 output arrives late too, and HBM is the highest-margin product in memory, which is why the memory names keep surfacing in our free report on the companies driving the AI expansion beyond the chipmakers (you can grab it here).

Industry sources offered three explanations. Rising general-purpose DRAM prices may be drawing investment toward conventional memory, and the first capacity at the Yongin cluster’s Y1 fab is reportedly going to general DRAM.

The third explanation is a technical issue in HBM4 back-end processing, but it is speculation with no confirmed link to the timing. A securities analyst quoted in the report called quality concerns excessive. One source also said the company’s 2027 investment plan remains uncertain internally.

A Reallocation Inside a Memory Boom

The deferral most likely reflects a reallocation. When conventional DRAM pricing competes with HBM4 for capital, the company is choosing between two profitable products, and that choice reflects strong demand.

The same night, the dominant lithography supplier said its planned 2027 and 2028 supply will not fully meet customer demand. Those two facts fit together because wafer tools are scarce, and packaging capacity is useless without wafers to fill it.

Analysts lean the same way, with five Strong Buy ratings, nine Buy ratings, and one Hold. The stock trades at 10 times trailing earnings and 5 times forward earnings. One major bank just raised its global memory market forecast to $2 trillion by 2030, up from $1.8 trillion.

Where the Bear Case Holds Weight

Rivals are competing hard in HBM4, and the timing of qualification with the largest accelerator customer will decide market share. A confirmed packaging problem would be expensive and would weaken the case for a simple reallocation.

The memory cycle is the larger worry. One market observer wrote that “memory stocks have always begun their cyclical decline when gross margins peak,” and SK hynix’s gross margin stands at 60.41%. Price targets are estimates, and in cyclical sectors they often lag the share price on the way down.

What Would Confirm the Case for SK hynix

The case for SK hynix strengthens if the deferral turns out to be capital moving toward conventional DRAM while HBM4 qualification stays on schedule, but it weakens if the company confirms a back-end processing problem or loses ground with its largest accelerator customer. The first case looks more likely.

At 5 times forward earnings after seven straight losses, the selling looks more like investors repositioning than a break in the HBM4 thesis. Analyst targets sit well above the share price, although large price swings are likely because the stock has a beta of 2.391.

Micron offers comparable memory exposure without Korean won risk. The stock is priced at $953.19 against an average target of $1,560.57, an implied upside of about 63.7%. However, Micron is up 234.18% this year and trades at 7 times forward earnings, which leaves SK hynix cheaper on forward earnings for the same underlying demand.
