SK Hynix Q3 Earnings Preview: Can HBM4 Ramp-Up and DRAM Price Hikes Sustain High Margins?
nashnova research
SK Hynix reports Q3 on October 28 after posting a 76.3% operating margin last quarter — ahead of TSMC and Micron. The market debate: whether HBM4 ramp and rising DRAM prices can hold that level, or the cycle is already turning.
How did last quarter's margin hit 76%?
Q2 revenue came in at $54.55 billion with roughly $45.2 billion in operating profit. EBIT margin hit 76.3% on a KRW basis — above TSMC's 60.3% and Micron's 67.6%.
Revenue missed consensus by about 4%. Management explained that roughly 50% of shipments are locked into multi-year contracts, and some high-value DRAM and HBM shipments were deliberately pushed to H2.
This means → the company traded "sell a bit less now" for "lock in prices long-term." The high margin came not from a demand surge but from selective shipment — shipping only the most profitable orders.
Where does HBM4 production stand?
SK Hynix began mass-producing and shipping 12-layer HBM4 chips in Q2. HBM — high-bandwidth memory — stacks multiple DRAM dies vertically to feed data-hungry AI processors.
Management said yield and quality are already approaching levels of the mature HBM3E product. In plain terms = the new-generation chip is barely producing scrap right off the production line, which is unusually fast for semiconductors.
Oakoff Investments argues this sharply reduces early-ramp waste risk. As long as HBM volumes keep climbing, the 76% margin has a foundation to hold.
DRAM and NAND prices are rising — will that continue?
Q2 numbers: DRAM blended ASP rose 30% quarter-on-quarter; NAND flash ASP jumped over 50%. Management guided Q3 DRAM bit shipments up 10% QoQ, with H2 ASP expansion faster than H1.
TrendForce forecasts: Q3 DRAM contract prices up 13%-18%, NAND up 10%-15%; Q4 DRAM increases may reach 20%.
This means → at least through year-end, pricing favors sellers. SK Hynix's margin has a price tailwind behind it — not just product-mix optimization.
How high are Q3 expectations?
Consensus calls for adjusted EPS of $6.25, GAAP EPS of $6.12, and revenue of $74.81 billion. Over the past 90 days, EPS estimates saw zero upward and one downward revision.
Oakoff Investments notes that with one negative revision already behind, beating this bar should not be difficult. Bank of America expects management may deliver a strong Q4 outlook on October 28 and potentially announce a special cash dividend.
Nanya Technology has already issued an upbeat Q4 forecast, with PC memory monthly contract prices up 15%+ and spot prices steady — providing independent support for an optimistic guide.
What are the biggest risks?
Oakoff Investments flags four: ① memory cycles often turn before most investors notice; ② memory pricing is highly transparent — good news may be already priced in; ③ a miss could trigger a sharp sell-off; ④ if Chinese memory makers prove their technology is closing the gap, all memory stocks get punished.
Bank of America reports a split among Singapore-based investors: hedge funds lean bearish, most long-only funds remain bullish. Concerns center on high borrowing costs at AI cloud companies, rising Chinese memory supply, and slowing AI spending.
This reflects a market that does not doubt SK Hynix's fundamentals — it is debating where in the cycle the stock sits. The question: are you buying a great company, or a cycle that has already peaked?
How cheap is the valuation?
On FY2027 consensus EPS of $32.73, the forward P/E is just 4.37x. Oakoff Investments assumes FY2027 EPS of $35, applies a 5-8x multiple, and arrives at a target of roughly $227.50.
The stock is about 28% off its all-time high, swinging between $124.80 and $199.87 over the past three months.
Put simply = the valuation looks cheap, but that discount is the cycle tax. Whether Q3 guidance lands strong and the special dividend materializes are the key checkpoints for the discount to narrow — or widen.
