SK Hynix makes memory chips such as DRAM and NAND flash, and profit is especially concentrated in high-bandwidth memory (HBM), which sits next to the GPUs in AI servers and where it holds the world's top market share. In the first quarter of 2026 it posted record results for the company's history, topping ₩50 trillion in quarterly revenue for the first time at ₩52.6 trillion, with operating profit of ₩37.6 trillion (a 72% operating margin). The key points to watch are that, while AI demand and tight memory supply persist, the company is strong thanks to high profitability and a net-cash balance sheet, but that once signs of oversupply or slowing AI investment appear, its cyclical nature means prices and profits could wobble together.

🔎 In-depth analysis

🏢Business
  • For SK Hynix, memory chips that store data are almost the entire business.
  • It mainly makes DRAM (chips that temporarily hold data during computation) and NAND flash (storage chips that retain data even when power is off).
  • The core of profit these days is HBM, a high-value type of DRAM.
  • HBM is stacked right next to the GPUs used for AI training so that data can be exchanged quickly.
  • Here the company holds the world's top market share and supplies Nvidia as its main customer, while it also sells high-capacity DRAM modules for servers and enterprise SSDs.
📈Price & chart
  • The latest closing price is ₩2,186,000 and the market capitalization is ₩1,558.0 trillion.
  • The price sits below the 20-day moving average (₩2,484,500) and above the 60-day average (₩1,964,083).
  • With short- and medium-term trends diverging, the direction should be read separately.
  • The RSI (a supplementary gauge that compares upward and downward force over the last 14 days on a 0-100 scale) is 46.3, a neutral level.
  • The one-month change is +6.7%, the three-month change is +138.7%, and the position versus the 52-week high is -25.1%.
  • Relative strength against the KOSPI is 95 (on a 1-99 scale, converted from the past year's return versus the index with recent periods weighted more heavily; higher means stronger than the market).
  • That places it in roughly the top 4% of all stocks by strength.
  • Over the last three months it outpaced the index by 70.4%.
  • Chart reading is best done alongside trading volume and the dates on which disclosures occurred.
📊Key metrics
  • Profitability is very high.
  • The ROE (how much is earned in a year per unit of equity) is 35.6%, a rare level in manufacturing.
  • The operating margin reaches 48.6%.
  • The balance sheet is solid too.
  • The debt ratio (debt relative to equity) is a low 46%, and the company is in a net-cash position with more cash than borrowings.
  • Net debt is about minus ₩12 trillion, meaning cash would remain even after repaying all its debt.
  • The free-cash-flow yield (actual cash generated relative to market cap) is about 1.6%.
  • The current share price is priced more on future profit growth than on this cash-generating power.
  • The headline P/E ratio (how many times one year's profit the share price is) of 36.30x and P/B (how many times net assets the share price is) of 12.93x look high, but they should be read bearing in mind that they are based on 2025 results, when profits had only just begun to surge.
🚀Growth
  • Earnings are climbing quickly from a cycle trough toward a peak.
  • In 2023 the company was in the red, with a ₩7.7 trillion operating loss amid a memory downturn.
  • It turned profitable in 2024, and in 2025 it posted ₩97.1 trillion in revenue and ₩42.9 trillion in net profit, a 117% year-on-year rise in net profit.
  • The rebound grew steeper heading into 2026.
  • First-quarter 2026 net profit was ₩40.3 trillion, up roughly 398% from the same quarter a year earlier.
  • Going forward, while AI server investment continues, the company sees demand for HBM and high-capacity DRAM outstripping supply.
  • Given that it earned this much even though the first quarter was a seasonally slow period, annual profit this year is on track to jump well above last year's.
📰Recent news & filings
  • Recent disclosures are clustered around earnings, shareholder returns and governance.
  • The April earnings release confirmed the first quarter to top ₩50 trillion in revenue and the largest operating profit ever.
  • In May the company decided on a disposal of treasury shares and filed its first-quarter report and corporate governance report.
  • There were no capital-raising disclosures such as large contracts or rights offerings, and June's disclosures were mostly reports of changes in executive and major-shareholder stakes.
  • The dividend is around ₩3,000 per share, so the payout relative to profit is a low roughly 5%.
  • This shows a growth phase in which most of the cash earned is spent on capital investment.
🧭Bottom line
  • The strengths are clear.
  • As the world's number one in HBM, profit is concentrated there, and it also has a net-cash position with high profitability.
  • The reason the headline P/E is high now is that profit is at an inflection point where it is just surging.
  • On this year's expected profit the share price is actually on the lower side, and even against pure-play memory peers it sits in a cheap spot.
  • The caution is that memory is inherently a cyclical industry.
  • Prices are rising now because of tight supply, but at some point, if capacity expansion outstrips demand, prices and profits could bend downward together.
  • Whether AI investment slows or a rival's volumes surge notably is the key condition to watch for this stock.

🔎 Valuation vs peers Undervalued

Compared against a representative domestic listed diversified chipmaker on the basis of the pure memory-chip business; Samsung Electronics mixes foundry, mobile and appliances in with memory, so it serves only as a reference for pure-memory profitability.

PeerP/EP/BROE
Samsung Electronics36.72x3.83x10.43%

The headline P/E of around 34x and P/B of around 12x look more expensive than reality because they are calculated using 2025 results, when profits had only just begun to surge, as the denominator. For an inflection stock like this, whose profit springs from a cycle trough to a peak, judging by last year's metrics alone misses the picture. In the first quarter of 2026 alone it earned ₩40.3 trillion in net profit, and with memory prices continuing to rise as the year progresses, recalculating on this year's expected profit brings the share price down to a far lower multiple. Even compared with overseas pure-play memory peers, the price relative to profit is on the cheap side. Although its ROE is more than three times that of fellow domestic chip leader Samsung Electronics, relative to profit growth it is judged to sit in undervalued territory.

📖 Plain-language glossary — expand if you are new to this
P/E
How many times a year's net profit the price is worth (lower is cheaper relative to earnings). The P/E here is on trailing (last full-year) results; for companies whose earnings swing fast (memory chips and other cyclicals/high-growth), a forward P/E on this year's expected earnings is more accurate.
P/B
Price relative to net assets (equity). Around 1x means it trades near book value; below 1x means below book.
P/S
Price relative to a year's revenue — useful for growth companies with thin earnings.
Net debt / EV
Net debt = interest-bearing debt − cash. Negative means more cash than debt (net cash). EV (enterprise value) = market cap + net debt, closer to what it would cost to buy the whole business.
EV/EBIT · EV/EBITDA · EV/Sales
Enterprise value against operating profit (EBIT), EBITDA, or revenue. Unlike P/E these reflect debt and cash; lower is cheaper relative to earnings power or sales.
FCF / FCF yield
Free cash flow = operating cash − capex, the cash actually left over. FCF yield = FCF ÷ market cap; higher means more cash generated per unit of market value.
Intrinsic value (DCF)
Future free cash flow (or, for some capex-heavy but profitable names, forecast earnings) discounted to today to estimate per-share value. Because it shifts a lot with the discount-rate and growth assumptions, it is shown as a bear/base/bull range, and the basis and assumptions are disclosed in one line beneath it.
ROE
How much profit the company earns in a year on its equity (%). Higher means better returns on capital.
EPS / BPS
Earnings per share / net assets (book value) per share.
Operating / net margin
Profit left from the core business / final profit after tax and interest, per unit of revenue.
Debt ratio
Debt relative to equity (%). Higher means more reliance on borrowing (norms vary by sector).
Current ratio
Assets convertible to cash within a year against debt due within a year. Above 100% leaves some short-term headroom.
Interest coverage
How many times operating profit covers the interest owed. Below 1x means operating profit alone struggles to cover interest.
Dividend yield / payout ratio
The year's dividend as a % of today's price / the share of earnings paid out as dividends.
Revenue CAGR
Multi-year growth expressed as a single yearly average (compound annual growth rate).
RSI (short-term signal)
Whether recent price action is overheated or beaten down. Above 70 is overbought, below 30 oversold.
MA20 / MA60 (moving averages)
The 20- and 60-day average price. Price above them signals a firmer short-term trend.
vs 52-week high
How far below the past year's peak the price sits now (%).
