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

A Discounted Cash Flow model takes estimates of the cash a company may generate in the future, then discounts those amounts back to today to arrive at an estimate of what the business could be worth now.

For SK hynix, the model used is a 2 Stage Free Cash Flow to Equity approach, based on cash flow projections in ₩. The latest twelve month free cash flow is ₩39.0b. Analyst estimates and Simply Wall St extrapolations project free cash flow reaching ₩347.2b in 2035, with interim projections such as ₩146.7b in 2026, ₩215.1b in 2027 and ₩240.9b in 2028.

Discounting these projected cash flows back to today produces an estimated intrinsic value of about ₩4,298,015 per share. Compared with the recent share price of ₩1,648,000, the DCF output implies the stock is about 61.7% undervalued under these assumptions.

Approach 2: SK hynix Price vs Earnings

For profitable companies, the P/E ratio is a useful shorthand for how much investors are paying for each unit of current earnings. It is easy to compare across companies in the same sector and ties directly to what the business is already earning today.

What counts as a “normal” P/E depends on how the market views a company’s growth prospects and risks. Higher expected growth and lower perceived risk usually support a higher P/E, while slower growth and higher uncertainty tend to justify a lower one.

SK hynix currently trades on a P/E of 15.39x. This sits below both the Semiconductor industry average of about 29.91x and a peer group average of 52.51x. Simply Wall St also calculates a proprietary “Fair Ratio” for SK hynix of 61.62x, which reflects factors such as earnings growth expectations, profit margins, industry, market cap and company specific risks.

This Fair Ratio is more tailored than a simple peer or industry comparison, because it adjusts for the specific profile of SK hynix rather than assuming all semiconductor companies deserve similar valuations. Comparing the Fair Ratio of 61.62x with the current P/E of 15.39x suggests the stock screens as undervalued on this measure.

Result: UNDERVALUED
