SK hynix’s 2026 Q2 earnings report “blows up”: operating profit missed expectations, with a further 8% drop after-hours.

Let’s start with the core numbers.
SK hynix’s 2026 Q2 operating profit is about $43.3 billion, while the market expected around $46 billion. The gap is $2.7 billion—below expectations.
In US after-hours trading, it immediately fell 8%, breaking below $110.
The year-over-year growth rate is still at a historic-level rise, since the same period in 2025 had a very low base. But what the market watches is always expectations—this time it was more like a “high open, then low finish” move.
Some key data
1. NAND demand guidance
For 2026 full-year NAND flash memory market demand, it is expected to grow year over year by 15%-19%. The growth rate is only very average.
2. Q2 price situation
DRAM average selling price rose about 30% quarter-over-quarter (QoQ) from Q1
NAND flash average selling price increased about 55% QoQ
3. Q3 shipment guidance
DRAM shipment volume is expected to grow about 10% QoQ
NAND shipment volume is expected to rise “slightly”
There’s something worth mulling over here: Q2’s price increase is already quite aggressive, but by Q3, the official shipment growth rate guidance clearly slows down—especially for NAND, which is only “slightly up.” It suggests that the pace of this round of core product price hikes may be starting to lose steam.
4. Downstream impact
Due to insufficient supply of storage chips, the shipment volume of businesses related to phones and PCs in the short term will be adjusted.
The signal behind this statement is also worth noting: it’s not that “phone/PC makers don’t want chips,” but that “chip supply can’t keep up,” forcing downstream terminal makers to adjust their shipment schedules accordingly.
To a certain extent, it also reflects that terminal demand isn’t as resilient as imagined—supply tightness and demand weakening may be interacting with each other.
5. Key actions in the second half
In the second half, SK hynix will expand its HBM4 memory supply volume, continuing to shift resources toward AI servers—where growth and margins are higher. This is the most profitable part.
Overall
This earnings report paints a fairly contradictory picture: single-quarter profits are still at an all-time high level, and price increases are also very strong, but profits miss expectations, shipment guidance slows, and downstream adjustments stack up—these three signals together may prompt the market to start reassessing how long this storage price-hike cycle can continue to “rise smoothly.”
For this storage-chip supercycle, the upcoming earnings reports of Samsung Electronics and Kioxia (to be released throughout this week) are also worth comparing—see whether SK hynix’s situation is a one-off case, or whether the whole industry is beginning to show similar marginal-change signals.
