Approach 1: SK hynix Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model estimates what a business is worth by projecting the cash it can generate in the future and then discounting those cash flows back to today in ₩ terms.

For SK hynix, the latest twelve month Free Cash Flow stands at roughly ₩20.9 trillion. Analysts project strong growth over the next few years, with Free Cash Flow expected to rise to around ₩41.3 trillion by 2026 and ₩53.8 trillion by 2027. Beyond the explicit analyst horizon, Simply Wall St extrapolates these trends, with modeled Free Cash Flow reaching about ₩104.8 trillion by 2035, using a 2 Stage Free Cash Flow to Equity approach.

When all these projected cash flows are discounted back, the model arrives at an intrinsic value of about ₩1,321,270 per share. Compared with the current market price, this implies a 56.8% discount, suggesting the shares trade well below the modelled long term value.

Result: UNDERVALUED

Approach 2: SK hynix Price vs Earnings

For a profitable business like SK hynix, the Price to Earnings (PE) ratio is a useful way to gauge value because it directly links what investors are paying to the company’s current earnings power. In general, higher expected growth and lower perceived risk justify a higher “normal” or “fair” PE ratio, while slower growth or more uncertainty call for a lower one.

SK hynix currently trades on a PE of about 11.0x. That is well below the global Semiconductor industry average of around 16.6x, and dramatically below the 32.9x average of its peer group, which reflects how highly many AI and memory names are being priced right now.

Simply Wall St’s Fair Ratio framework goes a step further by estimating what PE multiple SK hynix should trade on, given its earnings growth outlook, margins, industry position, market cap and risk profile. For SK hynix, this Fair Ratio comes out at roughly 32.4x, which is much higher than its current 11.0x multiple. On this basis, the stock appears meaningfully undervalued relative to what its fundamentals would justify.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your SK hynix Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let us introduce you to Narratives, a simple way to connect your view of SK hynix’s future with a concrete financial forecast and Fair Value on the Simply Wall St Community page, where millions of investors share their perspectives. A Narrative is just your story behind the numbers, where you decide how fast revenue grows, what happens to earnings and margins, and what a reasonable multiple looks like. The platform instantly translates that into a Fair Value you can compare with today’s price to help you judge whether to buy, hold, or sell. It then automatically updates your Narrative when new information, like fresh earnings or HBM4 news, arrives. For example, one SK hynix Narrative might assume strong AI memory demand, rising margins and a Fair Value well above the current price. A more cautious Narrative could focus on geopolitical and capex risks, softer NAND conditions, and a lower Fair Value closer to or even below where the stock trades today.
