Fun facts about AMKOR TECHNOLOGY, INC.

Quirks, history, and lore behind AMKR — the kind of stuff that makes a stock memorable.

1
The Basics
U.S. semiconductor services company · mid-cap · listed on Nasdaq · headquartered in Arizona.
2
The Numbers
Annual revenue in the range of $6–7 billion, with dozens of manufacturing facilities spread across Asia and beyond — because this business lives where the chips are actually made.
3
The History
Founded in 1968 in South Korea, it was built by a Korean-American entrepreneur and eventually moved its corporate home to the United States while keeping most of its factories in Asia.
4
The Secret
It doesn't design or fab chips — it does the packaging and testing that happens after fabrication, the unglamorous step that turns a wafer into a working part you can actually solder down.
5
The Lore
It is one of the world's largest outsourced semiconductor assembly and test (OSAT) providers, serving chipmakers who'd rather not run their own back-end factories.
6
The Giveaway
Its ticker rhymes with a poker hand, its founding family still holds significant control, and if you've ever held a smartphone, GPU, or automotive chip — odds are this company touched it last.

AI Insight: AMKR Financial Trends

AMKR delivered record Q4 2025 net income of $172M and revenue of $1,888M, but debt surged 43% year-over-year to $1,824M at its Q3 2025 peak before partially unwinding.

• Revenue grew year-over-year in every comparable quarter: Q3 2025 hit $1,987M vs. $1,862M in Q3 2024, a 6.7% gain.

• Operating margin expanded from 8.2% in Q2 2025 to 9.8% in Q4 2025, with Q4 2025 op income reaching $185M.

• Total debt jumped from $1,109M in Q2 2024 to a peak of $1,824M in Q3 2025, a 64% increase in five quarters.

• Q1 2026 operating cash flow of $145M is thin relative to the $644M generated in Q4 2025, reflecting typical seasonal softness.

⚠ Debt remains elevated at $1,425M in Q1 2026 vs. $1,109M in Q2 2024 — monitor whether deleveraging continues.

⚠ Q1 2026 net income of $83M is well below Q4 2025's $172M; watch if margin compression persists into Q2 2026.

⚠ Equity grew steadily from $4,050M to $4,534M over eight quarters, signaling retained earnings accumulation.

AI Insight: AMKR Ratio Trends

Q4 2025 delivered AMKR's strongest quarterly profitability in the dataset, but Q1 2026 seasonal reset and rising leverage warrant close monitoring.

• Operating margin peaked at 9.8% in Q4 2025, up from a trough of 2.4% in Q1 2025, showing sharp intra-year recovery.

• ROE surged to 15.4% in Q4 2025 from 2.0% in Q1 2025, then pulled back to 7.3% in Q1 2026 — consistent seasonal pattern.

• D/E ratio climbed from 0.27 in Q2–Q3 2024 to 0.42 in Q3 2025 before easing to 0.31 in Q1 2026, indicating rising then partially unwound leverage.

• TTM NPM of 6.2% and ROIC of 9.0% reflect solid full-cycle profitability despite Q1 2026 seasonal softness.

⚠ D/E spiked to 0.42 in Q3 2025 — highest in the dataset — before retreating; sustained deleveraging trend needs confirmation.

⚠ Q1 2026 OpMargin fell to 5.9% vs. 9.8% in Q4 2025; whether Q1 seasonality deepens or stabilizes sets the tone for 2026.

⚠ ROIC of 6.7% in Q1 2026 versus 12.5% in Q4 2025 — watch for Q2 2026 recovery to confirm the Q4 2025 peak was not a one-off.
