Revenue: $1.99B actual versus $2.04B estimated, a miss.
  • After-hours price: $38.11, down 3.03% from the $39.30 regular-session close.
  • Trading volume: 21,275,218 shares versus an average of 4,627,728.
  • Prior EPS results beat estimates in four straight quarters: $0.70 versus $0.47, $0.33 versus $0.23, $0.69 versus $0.43, and $0.51 versus $0.42.

    • A Break in AMKR's Earnings Momentum

    The two misses put both top-line execution and profitability under pressure. Revenue came in at $1.99B against $2.04B expected, while EPS reached $0.76 against $0.783 expected. AMKR missed across both major headline measures.

    The after-hours reaction adds weight to the negative read. AMKR fell from $39.30 to $38.11, while trading volume reached 21,275,218 shares against a 4,627,728 average. The response was active rather than a quiet after-hours move.

    On the earnings call, management's explanation of the $1.99B revenue result and $0.76 EPS result will frame whether this miss is isolated or part of a trend. The result also breaks a four-quarter EPS beat streak, making the current report a clear change in AMKR's recent earnings pattern.
