Amkor Technology stock is coming off a sharp pullback after a strong 80.0% return over the past year, while the company still screens as undervalued on broad valuation checks. Investors now need to weigh that recent volatility against the market’s current pricing of its AI focused partnerships and expansion plans
- Over the past 1 year, Amkor Technology has returned 80.0%, which sets a high bar for what future fundamentals need to justify.
- The multi year partnerships with Nvidia and other large chip companies can support expectations for future packaging demand, while a recent share price drop following a weaker revenue outlook highlights the risk that growth expectations may prove too optimistic.
- On Simply Wall St’s checks, Amkor Technology screens as undervalued in 6 of 6 valuation tests, which means the broader metrics still lean cheap despite the strong 1 year return.
The issue now is whether the recent sell off has simply reset expectations for Amkor Technology or if the stock’s strong 1 year run already reflects most of the good news in the current valuation

Is Amkor Technology Still Cheap on Earnings?
The P/E ratio suits Amkor Technology because earnings are a core focus for how investors compare semiconductor stocks. Amkor Technology currently trades on a P/E of about 19.1x, which sits well below the Semiconductor industry average of roughly 53.6x and below the peer average of about 64.2x. That gap means the market is pricing each dollar of Amkor Technology earnings at a clear discount to many other listed chip companies
The fair P/E ratio implied by Simply Wall St’s model is about 42.7x, based on factors such as the company’s scale, industry, margins and risk profile. Against that benchmark, the current 19.1x multiple is much lower, which indicates that Amkor Technology may be undervalued on this earnings measure. Despite recent excitement around the Nvidia partnership and record Q2 2026 revenue, the P/E still sits well under both the fair ratio and the broader sector averages
On the P/E multiple alone, Amkor Technology stock currently screens as undervalued compared with both its modelled fair ratio and the wider Semiconductor industry

The Bottom Line
For Amkor Technology, the valuation still leans undervalued on earnings, even after a strong 1 year run and recent volatility. The key question is whether that discount reflects genuine mispricing or a market that is rightly cautious about how much packaging growth and AI related demand will actually flow through to sustainable earnings. The crux for both bulls and bears is whether margins and demand from major partners can support a higher P/E over time, rather than the stock simply settling in as a lower multiple way to get exposure to the semiconductor cycle.
