The five investor questions

44

2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue $6.1B to $6.7B, increasing; diluted EPS 2.62 to 1.50, decreasing.

23

Median gross margin 17.1% over 10y, stable.

83

Median ROIC 18.5%, above the 12% hurdle in 70% of years.

65

Net debt/EBITDA 0.1x, interest coverage 6x.

62

Owner earnings changed +8.8%/yr over up to the ten most recent annual observations.

Price vs. value if growth stopped today

A cautious baseline, not a price target: what the shares may support if normalized owner earnings simply hold steady.

287% above value if growth stopped today

What today’s price assumes: owner earnings growing ~31%/yr over 5 years. The zero-growth estimate assumes owner earnings stay flat (0% growth).

How to read this

We solve for the constant annual change in owner earnings that would make the five-year zero-growth estimate equal today’s price. This keeps the existing model inputs and calculation unchanged; it is an expectations lens, not a forecast.

This zero-growth estimate assumes trailing owner earnings persist — unreliable for declining businesses. The recent FY revenue series does not trigger the three-consecutive-declines flag.

Among the current top-score group, the median current price is 239% above the zero-growth estimate across 48 of the current top 50 companies by Moat Score with both values.

19 years of fundamentals

The business, in plain English

AMKOR TECHNOLOGY, INC. booked $6.7B of revenue in FY2025 in the Technology sector and kept 14.0% of it as gross profit — a thin-margin business by that measure. After every other cost, 5.6% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $2.7B (FY2008) to $6.7B (FY2025) — about 5.6% a year compounded over 17 years.

It earned 8.7% on invested capital in the latest filed year, FY2025. Across the full 16-year measurable filed record, median ROIC was 16.3%. Over the v3 recent window (10 measurable filed years), median ROIC was 18.5%. The Returns on Capital filter above scores it 83/100.

The balance sheet carried $1.5B of total debt in FY2025 against $374M of owner earnings — roughly 3.9 years of owner earnings to retire it all. Balance-Sheet Safety scores it 65/100.

Put together: Returns on Capital is the strongest of the five filters (83/100) and Pricing Power the weakest (23/100), which is how AMKR lands at 55/100 — a Shallow moat.

This breakdown is generated from the filed numbers and sub-scores above — no outside narrative, no estimates. Where a filing doesn’t disclose an input, the sentence that would need it is omitted instead of guessed.

Insider activity

Form 4 reports mix P/S market or private transactions with compensation-plan mechanics. Activity casually described as “insider selling” can include compensation mechanics; awards, tax withholding, and option exercises are shown by their exact filed class here, never collapsed into “Bought” or “Sold.”

These are disclosed filing facts and arithmetic aggregates, not a signal or verdict.

Common questions about AMKR

Does AMKOR TECHNOLOGY, INC. have an economic moat?
Based on its FY2025 SEC filings, the Moat Index scores AMKOR TECHNOLOGY, INC. (AMKR) 55.4 out of 100 — a Shallow moat. The five questions behind that score begin at 20% each; if exactly one genuinely lacks data, the other four weights are renormalized and disclosed. revenue and EPS trend 44, pricing power 23, returns on capital 83, balance-sheet safety 65, capital allocation 62.
Is AMKR trading below the conservative owner-earnings estimate?
The value if growth stopped today — a zero-growth baseline — is $16.80 per share. It capitalizes normalized owner earnings at a 9% rate and assumes 0% growth. Versus a recent price of $64.96, that is 287% above value if growth stopped today. The model also publishes a capped-growth comparison, but the zero-growth estimate is the cautious baseline. It assumes trailing owner earnings persist and is unreliable for declining businesses. This is an educational estimate from primary SEC filings, not intrinsic value as a fact or investment advice.
How has AMKR's Moat Score changed over time?
The record logs 16 readings since Jul 17, 2026; the latest reads 55.4 out of 100 (shallow moat). No tier changes on record yet. (Methodology or normalizer upgrades on Jul 20, 2026, Jul 23, 2026, Jul 26, 2026 re-based the score; readings across versions aren't compared.) The history is append-only — readings are only ever added, never rewritten.
