Amkor Technology, Inc. (AMKR): fair value, margin of safety and Wheel Score
Technology · Semiconductors · United States · Blend
Is AMKR undervalued?
At 44.05 (close of 16 Oct 2026), AMKR trades 39% over the GLS average fair value of 31.63, with 2 of 9 models above the price. The stock earns none of the Wheel Score's Value points at this price. That is a statement about price against trailing fundamentals, not about the company's prospects - the Wall Street View and the Growth tab on the Quote page carry the forward numbers.
There is a wide gap between DDM (4.92) and Graham Growth (72.76). When the models are this far apart the "fair value" is really a range, and the margin of safety above should be read with that range in mind.

Quality and financial health
Amkor Technology, Inc. scores 6 of 9 on the Piotroski F-score: a middling result that passes the Sunday Scan's "6 or more" rule. Some of the nine tests on profitability, leverage and efficiency are failed, so the accounts are worth a look before selling a put on the name. On durability AMKR scores 5.1/10 on the GLS Moat - a middle reading; the Scorecard on the Quote page's Financials tab shows which ten-year lines are steady and which are not.
Returns on capital are moderate - ROIC 6.2%, ROE 8.4%, ROA 4.6% - with debt at 0.35 times equity and a free-cash-flow yield of 4.7%.
The dividend yield is 0.76% with a payout ratio of 15% - a small yield that leaves most of the earnings in the business. Revenue comes mainly from Advanced Products 82%, Mainstream Products 18% (quarter Q2 FY2026).
Institutional ownership scores 6/10, insider activity 6/10 and Congressional trading 5/10 on the GLS smart-money scales; the last recorded insider buy was on 22 Sep 2026.
| Piotroski F-score | 6 / 9 | ROIC | 6.2% |
|---|---|---|---|
| GLS Moat | 5.1 / 10 | ROE | 8.4% |
| Debt / equity | 0.35 | ROA | 4.6% |
| Free-cash-flow yield | 4.7% | Payout ratio | 15% |
| Institutions | 6 / 10 | Insiders · Congress | 6 · 5 / 10 |
Wheel Score 54: Fair
A Wheel Score of 54 puts Amkor Technology, Inc. in the Fair band - below the 70 the Sunday Scan requires. Value 0/25, Health 13/20, Moat 8/15, Premium 16/20 and Stability 17/20; the weakest part is Value (0/25).
Implied volatility is 75% on the near-the-money contracts 20-60 days out - above the 60% ceiling of the sweet spot. Premiums are large, but the Wheel Score tapers the Premium points (16 of 20) because volatility this high usually comes with a reason. The option chain is deep: 128,921 contracts of open interest across all expiries, which means tight fills at most strikes.
Volume runs at 5.0M shares a day on a market cap of $10.9B, with a beta of 2.22 - a high beta, so the stock tends to move more than the market and a strike can be gapped through; the Stability part of the Wheel Score gives that 17 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 0 / 25 | -39% margin of safety | |
| Health | 13 / 20 | Piotroski 6/9 | |
| Moat | 8 / 15 | moat 5.1/10 | |
| Premium | 16 / 20 | implied volatility 75% | |
| Stability | 17 / 20 | 5.0M shares/day, $10.9B cap, beta 2.22 |
