Amkor (NASDAQ:AMKR) misses Q3 analysts' revenue estimates

What happened

Amkor Technology missed analysts' revenue expectations in Q3 2026, with revenue flat year on year at $1.99 billion versus a $2.01 billion consensus. Its GAAP profit of $0.76 per share also fell below estimates, and Q4 revenue guidance of $1.95 billion underwhelmed.

Confirmed

Global impact / market context

A revenue miss plus soft guidance suggests demand may be cooling, which matters because slower sales can leave Amkor with less cash coming in while its costs and inventory remain. That combination can pressure profit per sale and limit room to fund capital spending.

Analyst inference

Amkor's operating margin rose to 11.3% from 8% a year earlier and inventory days increased to 34 from 32, showing better profitability but rising unsold stock. Management cited expected weakness in Communications, offset by record Computing and Automotive revenue.

Analyst inference

What to watch

1. Watch whether Amkor's Q4 revenue lands near its $1.95 billion guidance midpoint, which is below the $2.01 billion analysts expected, as a sign of demand trends. Confirmed
2. Investors could compare next quarter's operating margin with the 11.3% reported here to see whether profit per sale holds up if revenue comes in softer. Proposed
3. Track inventory days outstanding, which rose to 34 from 32, because further increases could mean Amkor is producing more chips packaging than customers are buying. Analyst inference
