SK Hynix HBM4 Order Lock-In Boosts Margins, Price Target KRW 3 Million
nashnova research
SK Hynix's HBM4 lock-in orders and scarcity pricing drove its quarterly operating margin to 71.5%. Nine brokerages set a median target of ₩2.6 million; a blended valuation points to ₩3.0 million — roughly 63% upside from the current price.
Where does a 71.5% margin come from?
Q1 2026 operating profit hit ₩37.6 trillion at a 71.5% operating margin — well beyond a normal cyclical recovery. This is peak-level, scarcity-driven pricing.
This means → SK Hynix is not just selling memory chips; it is selling something rivals cannot yet manufacture, giving it extraordinary pricing power.
DRAM — dynamic random-access memory, the most common memory in phones and servers — saw quarterly ASPs rise to the mid-60% range quarter on quarter. HBM4 — fourth-generation high-bandwidth memory, stacked memory built specifically for AI processors — commands a price roughly 40% above the prior-generation HBM3E.
How far can HBM revenue climb?
The base-case model projects HBM revenue in a three-year staircase: ₩52 trillion in 2026 → ₩72 trillion in 2027 → ₩100 trillion in 2028.
In plain terms = HBM revenue nearly doubles in three years — this is the main engine of the entire profit story.
HBM is always a subset of DRAM, not an addition to it. Volume and pricing trends in server DDR5, commodity DRAM, and enterprise SSDs will determine whether total operating profit can reach ₩260 trillion, ₩316 trillion, and ₩288.5 trillion in succession.
Why are brokerages switching valuation methods?
Nine houses put targets in a ₩1.3 million – ₩3.5 million range, median ₩2.6 million. Goldman Sachs, BofA, and Bernstein shifted to forward P/E; Citi uses sum-of-the-parts; Morgan Stanley uses a residual-income model.
This reflects a market willing to pay for the assumption that "multi-year high profits are sustainable" — no longer anchoring to current book value, but pulling 2027–2028 price-and-share delivery into the valuation today.
In plain terms = memory stocks used to be valued like steel mills — on net assets. Now the market values SK Hynix like a consumer-goods company — on how much it can earn over the next several years.
How is the ₩3.0 million target derived?
Four methods, blended: forward P/E → ₩3.135 million, DCF → ₩2.959 million, P/B → ₩2.989 million, SOTP → ₩2.955 million. Weighted result: ₩3.035 million, rounded to ₩3.0 million.
Against the July 13, 2026 close of ₩1.845 million, that implies roughly 62.6% upside.
This means → the four methods converge tightly, signaling a strong market consensus that SK Hynix is worth around ₩3 million.
What is the biggest risk?
The core downside is share and price falling together: Samsung and Micron encroaching on HBM4 share, commodity DRAM or NAND contract prices weakening early — profit and valuation multiples would compress simultaneously.
Long-term supply agreements lack price protection and cancellation penalties; elevated capex could release new supply — both factors that would drag normalized earnings lower.
As of Q1-end the company held roughly ₩35 trillion in net cash, with free cash flow rising fast. That provides a buffer, but it cannot offset a simultaneous decline in product share and memory pricing.
What to watch next?
The current 71.5% operating margin is a scarcity-pricing peak. Whether it can hold through the HBM4 mass-production ramp is the key test of the entire valuation thesis.
In plain terms = today's high margins rest on "demand outstripping supply." Once supply catches up — or customers cut orders — margins will retreat quickly. That is the single most important variable for anyone betting on the bull case.
