E/P over time
E/P = trailing-12-month diluted EPS / price at quarter end. E/P is the inverse of P/E and stays defined when earnings are negative.
Today's P/E sits at the 55 percentile of its own 40-quarter history (min 5.1, median 13.2, max 43.3; quarters with earnings only).

Memo
AMKOR TECHNOLOGY, INC. (AMKR). Latest full fiscal year: 2025; data up to 2026-09-30.
Figures computed from the financial statements: revenue 6.7 bn USD in 2025; YoY growth 6.2%; net margin 8.3%; ROE 13.6%; net debt/EBITDA 0.6x.
The estimated value range is 80.75–259.28 USD per share (median of 2 methods, agreement: low); assumptions are illustrative. Against the central value of 130.63 USD, the price of 35.66 USD leaves a potential of 266.3% (value / price − 1) and a margin of safety of 72.7% (1 − price / value). The range is the median of the methods' low, central and high values, not a probability interval.
olivLaw score 31/100, methodological classification: unattractive profile (score, margin of safety and method agreement together; not a judgement of the right price). Not investment advice.
Text generated deterministically from the figures shown; no language model. Not investment advice.
What supports the thesis
- Current ratio: 2.2x
- EV/Sales: 1.3x
- The price is below the estimated value range
What contradicts it
- Gross margin: 16.6%
- FCF margin: -2.1%
- Revenue CAGR 3Y: -1.8%
- FCF yield: -1.8%
- The valuation methods diverge

In brief
Amkor Technology is the largest U.S. headquartered outsourced semiconductor assembly and test provider, serving leading chipmakers. The company matters now because of rising demand for advanced packaging tied to artificial intelligence and large capacity investments, including in Arizona. Net sales in the third quarter of 2026 reached 1,991 million USD 3.
SWOT
Strengths
Weaknesses
Opportunities
Risks
- Semiconductor cyclicalityhigh
Industry or economic downturns can reduce demand and capacity utilization 1.
- Customer concentrationhigh
Large customers generate a major share of sales, and losing one could affect results 3.
- Large capital investmentsmedium
Capital spending is large and made ahead of revenue without firm customer commitments 13.
- Trade and tariffsmedium
Tariffs, export restrictions and regional conflicts can affect international operations 12.
- Material costsmedium
Materials, gold and other commodities have volatile prices, and long-term contracts with price adjustment are rare 1.
Investment thesis
What would need to be true (bull case)
- If demand for AI-linked advanced packaging continues, the company could benefit from its new capacity and rising margins.
- Its position as the largest U.S. headquartered OSAT could attract customers regionalizing their supply chains.
- The gross margin increase in the third quarter of 2026 shows better capacity use can support profitability 3.
What would break the thesis
- A slowdown in the semiconductor industry could reduce factory utilization given high fixed costs.
- Dependence on a few large customers could make revenue vulnerable to their decisions.
- Large capital spending and rising debt could limit financial flexibility if demand falls.
What to watch

The business
Amkor provides packaging and test services for integrated device manufacturers, fabless companies, OEMs and contract foundries 1. Its portfolio includes advanced packaging, wafer-level processing and system-in-package solutions for smartphones, data centers, artificial intelligence, automobiles and wearables 1. In fiscal 2025 net sales were 6708.0 million USD 1, and Advanced Products made up 82.8% of sales 1.
The strategy rests on three pillars: technology leadership in advanced packaging, a broader geographic footprint and deeper partnerships with lead customers 1. The company states its primary financial objective is profitable sales growth 1. It has no meaningful backlog, and customer commitments are short term 1.
Amkor is expanding production through a new Arizona facility, under construction since the second half of 2025, and by scaling its Vietnam facility, which opened in 2024 12. Capital spending has focused on advanced packaging and test equipment and the Arizona facility 1.
Segments
Market context
Packaging demand follows the semiconductor cycle, which is cyclical and tied to worldwide GDP and consumer spending 1. The advanced segment is driven by artificial intelligence, data centers and rising semiconductor content in automobiles 12.
In the third quarter of 2026, communications represented 37% of sales and computing 26% 3. Customer concentration remains high, with the top ten customers accounting for 66% of net sales 3.
Trends
- Artificial intelligence and HPCtailwind
Demand for advanced packaging grows as AI applications spread across data centers and edge devices 1. Computing sales rose 16% in fiscal 2025 on AI-related PC devices and networking 1.
- Rising semiconductor content in automobilestailwind
Chips for ADAS, electrification and infotainment raise content per vehicle and create demand for power packaging 12.
- Industry cyclicalityheadwind
The company says it cannot predict the timing or duration of any downturn or recovery 1. A downturn could reduce utilization 1.
- Tariffs and trade restrictionsmixed
Tariffs, export controls and related trade actions could affect customers and operations, though the impact depends on uncertain future developments 12.
Competitive position
Amkor competes with other independent OSAT providers, with integrated device manufacturers that package their own chips, and with contract foundries that also offer packaging and test 1. The company notes that prices have historically pressed margins downward 1.
Amkor's advantages include global scale, a diversified geographic footprint and long relationships with lead customers 1. Competitors may have in-house capabilities or different customer access, which could shift its position 1.
- Integrated device manufacturers (IDMs)
Package and test chips in their own factories but may outsource part of the work 1.
- Contract foundries
May offer packaging and test services to their own customers 1.
- Other independent OSAT providers
Compete directly on packaging and test services; the sources do not name them 1.
- Fabless companies with in-house packaging
May prefer internal solutions or other partners for packaging 1.
