SK hynix (NasdaqGS:SKHY) has become a focus for investors after the company approved roughly $38b of spending on two new memory chip plants in South Korea, with construction scheduled to start in 2027.

See our latest analysis for SK hynix.

SK hynix shares have pulled back despite earlier enthusiasm around AI driven memory demand, with the latest share price at $137.97 and the year to date share price return down 17.88%. This suggests that momentum has cooled as investors reassess execution risks around large scale capacity expansion.

Bulls see SK hynix using this US$38b build out and recent revenue and net income growth to reinforce its AI memory position. Bears focus on execution risk and share price weakness. Which side does the current valuation lean toward?

On the numbers available today, SK hynix trades on a P/E of 6.4x, which looks low compared to its peers and to the broader US Semiconductor industry.

The P/E ratio compares the current share price to earnings per share. For a company like SK hynix that operates in memory and storage semiconductors, investors often use P/E to gauge how much the market is paying for its profit profile relative to others in the sector.

Simply Wall St data indicates that SK hynix is considered good value on this measure against both peers with an average P/E of 61.3x and the US Semiconductor industry average of 52.6x. The stock is also flagged as trading at 74.3% below an internal fair value estimate and at a discount to an SWS DCF model future cash flow value of $535.91. This suggests the market is assigning a much lower earnings multiple than those reference points imply.

Result: Price-to-Earnings of 6.4x (UNDERVALUED)

However, SK hynix still faces risks if execution on the US$38b expansion stumbles or if memory pricing weakens, which could pressure earnings and investor confidence.

The P/E of 6.4x already presents SK hynix as inexpensive, but the SWS DCF model goes further. It estimates a future cash flow value of $535.91 per share versus the current $137.97, which suggests the stock is deeply undervalued on this framework as well. The key question is whether those cash flow assumptions still feel realistic to you.
