The next sections will walk through the key valuation approaches used to reach that view and will also point to a more complete way to think about valuation at the end of the article.

Approach 1: Amkor Technology Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model uses estimates of the cash Amkor Technology could generate in the future, then discounts those projected cash flows back to today to arrive at a single estimate of what the stock might be worth.

For Amkor Technology, the latest twelve month Free Cash Flow is about $312.4 million. Using a 2 Stage Free Cash Flow to Equity model, analysts supply cash flow estimates out to 2029, with Simply Wall St extending the projections further based on those inputs. Within this framework, forecast Free Cash Flow reaches $5,237.3 million in 2035, with interim years such as 2029 at $808.8 million and 2030 at $1,404.7 million, all in dollar terms.

After discounting these projected cash flows, the DCF model indicates an estimated intrinsic value of $122.36 per share. Compared with the recent share price of $86.72, this suggests the stock is around 29.1% below that intrinsic value estimate on this measure.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Amkor Technology is undervalued by 29.1%. Track this in your watchlist or portfolio, or discover 44 more high quality undervalued stocks.

Approach 2: Amkor Technology Price vs Earnings

For a profitable company like Amkor Technology, the P/E ratio is a useful way to check what you are paying for each dollar of current earnings. Higher growth expectations or lower perceived risk usually justify a higher P/E, while slower growth or higher risk tend to point to a lower, more conservative P/E range.

Amkor Technology currently trades on a P/E of 49.29x. This sits below the Semiconductor industry average P/E of 68.80x and also below the peer group average of 94.22x. On the surface, that might suggest the stock is priced more modestly than many Semiconductor peers.

Simply Wall St’s Fair Ratio for Amkor Technology is 46.98x. This is a proprietary estimate of what the P/E might reasonably be, given factors such as the company’s earnings growth profile, industry, profit margins, market capitalization and risk characteristics. Because it incorporates these company specific inputs rather than relying only on broad industry or peer comparisons, the Fair Ratio can provide a more tailored reference point. With the current P/E of 49.29x sitting close to the Fair Ratio of 46.98x, the valuation on this measure looks slightly higher than that reference level.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Amkor Technology Narrative

Earlier it was mentioned that there is an even better way to think about what Amkor Technology might be worth, and that is through Narratives. These are simple stories that you and other investors build on Simply Wall St’s Community page to link your view of the company to specific forecasts for future revenue, earnings and margins, and then to a Fair Value that you can compare to today’s price to help decide whether to act. The system updates your Narrative automatically when new news or earnings arrive. For example, one Amkor Technology Narrative might align with the higher Fair Value of US$90 based on assumptions closer to the more optimistic analyst cohort, while another might lean toward the lower Fair Value of US$60, capturing a more cautious view. Looking at both side by side helps you see which story about the company fits best with your own expectations before you commit capital.

For Amkor Technology however we will make it really easy for you with previews of two leading Amkor Technology Narratives:

Fair value: US$90.00

Implied discount to this fair value based on the last close: about 3.6%.

Revenue growth assumption: 11.68% per year.

• Assumes higher long term benefits from advanced packaging, AI related demand and the Arizona and global capacity build out than consensus currently reflects.
• Builds in revenue of US$9.8b and earnings of US$689.3m by 2029, with a future P/E of 45.2x and a discount rate of 11.5%.
• Flags customer concentration, margin pressure, heavy capital spending and geopolitical uncertainty as key risks that could challenge this more optimistic view.

Fair value: US$60.00

Implied premium to this fair value based on the last close: about 44.5%.

Revenue growth assumption: 7.07% per year.

• Focuses on risks from manufacturing onshoring, geopolitical shifts, in house packaging by customers and the possibility that heavy investment leads to overcapacity.
• Builds in revenue of US$8.7b and earnings of US$680.0m by 2029, with a future P/E of 31.4x and a discount rate of 12.5%.
• Accepts that advanced packaging demand and capacity expansion can support growth, but argues current market expectations may already price in much of that upside.

The gap between the US$90 bullish fair value and the US$60 cautious fair value shows how much your own expectations for Amkor Technology's growth, margins and risk should drive your decision. Before moving further, it can help to read each full Narrative, decide which set of assumptions feels closer to your view of the company and then test that against your wider portfolio and risk tolerance.
