C Fundamentals grade

Amkor Technology provides outsourced semiconductor packaging and test services — the stages that follow chip fabrication. Customers send it finished wafers, which it turns into packaged, tested chips ready for use in electronics. Its services span package design, wafer bumping, probing, back-grinding, assembly, burn-in and final testing, and it groups its offerings into Advanced Products (flip-chip, memory and wafer-level packages) and Mainstream Products (wirebond and power-device packages).

Its customers are chipmakers: integrated device manufacturers, fabless design firms, original equipment manufacturers and contract foundries, which outsource packaging and test rather than build their own facilities. Amkor earns fees for these services; the silicon wafers are generally consigned by customers, so it does not own them. Apple and Qualcomm are among its largest direct customers.

The chips it packages reach smartphones and tablets, data-centre and computing hardware, cars and industrial systems, and consumer devices. Amkor is headquartered in the United States, with manufacturing sites across Asia and Europe; it opened a plant in Vietnam in 2024 and began building one in Arizona in 2025. It describes itself as the largest US-headquartered provider of such services, with customer relationships spanning five decades.

Based on Amkor Technology, Inc.'s 10-K filed February 20, 2026.

Earlier notes (2)

10-Q filed July 28: Amkor Technology

Revenue for the twelve months to June 2026 reached $7.46bn, a 15.7% rise on a year earlier. That marks a slowdown from the 17.9% growth recorded a quarter earlier. Profitability sends mixed signals. Operating margin widened to 9.5% from 6.5%, yet free-cash-flow margin slipped to -2.1% from 3.6% a year earlier. On balance, the fundamentals grade moves from C to D. Our model value is little changed at $25.44 a share, well below the $38.66 share price, and the rating stays Sell. At that price the market is implying roughly 16.3% annual cash-flow growth over five years. That assumption sits far above the 4.0% annual revenue growth the company has actually delivered.

10-Q on SEC EDGAR

Where Amkor Technology stands after its latest 10-Q

Revenue for the twelve months to June 2026 was $7.46bn, up 17.9% on a year earlier, faster than 12.7% a quarter earlier. Free-cash-flow margin fell to -2.3% from 4.4% a year earlier. Operating margin widened to 8.6% from 6.4%. Against its peers on growth, profitability, cash generation and balance sheet, it grades C. It passes 4 of our 7 financial-health checks. Our cash-flow model value is $16.19 a share, against a share price of $42.00. At that price, our model says the market is pricing in about 23.5% a year of cash-flow growth for five years, faster than the 4.0% a year revenue growth it has delivered.

The Fundamentalytics view

Next results ~February 8, 2027 (estimated)

Amkor Technology, Inc.'s trailing-twelve-month revenue grew 15.7% year on year, with a free-cash-flow margin of -2.1%. Where it stands out: stock pay as % of revenue of 0.4% ranks 7 of 74 semiconductor companies we cover. Where it lags: gross margin of 16.6% ranks 67 of 73 semiconductor companies we cover.

Our discounted-cash-flow model values the business at ~$23 per share in the base case (~$17–$30 across growth scenarios) — model values under stated assumptions, not a price target.

Current signal Capital expenditure surging: TTM capex grew 120% year over year and now absorbs 22.4% of revenue.

Valuation

Amkor Technology, Inc. valuation models and calculator

What the price is pricing in

The share price implies about 19.5% a year of cash-flow growth for five years.That is faster than the 4.0% a year revenue growth Amkor Technology has delivered.

  • Priced in19.5%
  • Last 12 months15.7%
  • 3 years a year3.9%
  • 5 years a year4.0%

Our cash-flow model with every input fixed except growth over the next five years, solved for the growth at which the model value equals the share price ($38.75, Nov 3, 2026). Cash-flow growth then fades to 2.5% a year; discount rate 8.5%. Delivered figures are revenue growth from SEC filings.

How we got here: a discounted-cash-flow model of Amkor Technology, Inc.'s free cash flow after stock-based pay with after-tax interest added back ($223M, FY2026 Q3 TTM), growing 8.4% and 11.2% in the next two years (forecasts, guidance and its record), then back to 9.8% by year five, and fading to 2.5%, discounted at 8.5%. Lower and higher growth cases span ~$17–~$30 ; that spread sets a 25% margin before we rate Buy or Sell.

Produced by Fundamentalytics' automated valuation model on November 3, 2026, using delayed market prices. Rating meanings, methodology and conflicts: recommendations disclosure and research disclaimer. General research, not personal advice — it does not consider your circumstances. Prices can fall as well as rise.

Our value per share comes from a discounted-cash-flow model of Amkor Technology, Inc.'s free cash flow after stock-based pay ( $223M, FY2026 Q3 TTM, with after-tax interest added back): growth for five years as below (the first two years from forecasts, guidance and the company's record), fading to 2.5%, discounted at 8.5%, then cash added and debt and other claims subtracted. These are model values under stated assumptions, not price targets or recommendations.

Valuation models

We value Amkor Technology, Inc. as an operating company, with every model that fits that kind of business. Cost of equity 13.1%: the 10-year Treasury yield (4.9%) plus a beta of 1.82 times a 4.5% equity risk premium.

Options strategies

All options ideas

How Amkor Technology, Inc.’s listed options are priced, and three ways to use them that follow from our valuation. Quotes are delayed, read November 2, 2026. Check the live chain at your broker before trading.

Implied vs realised volatility

Options look cheap

Option prices imply less movement than the shares have recently shown. Selling options pays little for the risk taken.

  • Implied is 0.95× the last 60 days’ realised volatility , richer than 14% of the 229 stocks we screen today.
  • Puts and calls are priced at about the same implied volatility.
  • Why: implied is below 60-day realised: selling options pays little for the risk taken.

Our rule for “rich”: implied at least 1.2× 60-day realised (beyond measurement noise), above 1-year realised (not just a calm spell), and in the top 20% of our coverage that day. Never with results inside the option’s life. These are our conventions, built on research showing option prices usually imply more movement than follows, most when the gap is wide. How we judge this.

Cash-secured put

Not offered: rated Sell.

We suggest selling a put only on well-rated companies, at a strike where the price you would pay if assigned (strike less premium) is at or below our fair value.

Collar

Own the shares, buy the $34.00 put and sell the $42.00 call, both expiring December 18, 2026 (46 days).

  • Net cost of $0.80 a share ($80.00 per contract of 100 shares).
  • Worst case at expiry: -10.9%, if the shares fall below $34.00 (-8.7% from today).
  • Best case at expiry: +10.6%, if the shares rise above $42.00 (+12.8%); gains beyond that go to the call buyer.

Offered because the shares trade at or above our fair value of $23.00: a way to hold on with a floor under the price, paid for by giving up upside the model does not expect. Strikes near 25-delta; the put at its ask and the call at its bid. Protection has a cost over time: research on protective puts finds they have usually lowered returns.

General research, not personal advice. Options can lose you more than you expect and are not suitable for everyone: put sellers can be made to buy shares that keep falling, call sellers give up gains above the strike, and results or news can move prices sharply. Chances shown are approximations from each option’s delta. Spreads, fees and early assignment are not modelled.

Growth Profitability Cash Balance sheet Value

Growth, profitability, cash generation and balance sheet are percentiles against the companies we cover in the same industry, from SEC filings (100 = best). Value compares the share price with our modelled value range (50 = at our base value; higher = cheaper). A description of reported data and our model — not a quality score or advice.
