With shares reaching new highs, along with impressive revenue and income growth on display, investors are left to wonder if Amkor Technology is currently undervalued or if the market has already priced in all the future upside.

Price-to-Earnings of 29.2x: Is it justified?

At a last close price of $36.39, Amkor Technology currently trades at a price-to-earnings (P/E) ratio of 29.2x. This positions the company as a relatively cheaper option compared to both its direct peers and the broader semiconductor sector.

The price-to-earnings ratio reflects the market’s expectations for a company’s future earnings growth and overall profitability. A lower P/E compared to industry averages can suggest that the stock is undervalued relative to its profit potential, or it may reflect market skepticism about future growth sustainability.

With Amkor’s P/E below the US semiconductor industry average (36.1x) and below its peer group (39x), the stock looks attractively priced to earnings power on a relative basis. Additionally, the estimated fair P/E ratio of 35.2x indicates the market could gradually re-rate the stock upward if future growth matches expectations.
