Q1 2026 earnings snapshot

Amkor Technology (AMKR) opened 2026 with Q1 revenue of US$1.7b and basic EPS of US$0.34, alongside trailing twelve month revenue of US$7.1b and EPS of US$1.76 that frame the latest quarter in a broader earnings context. Over the past year, the company has seen revenue move from US$6.3b to US$7.1b on a trailing basis, while quarterly EPS stepped up from US$0.09 in Q1 2025 to US$0.34 in Q1 2026, indicating a different earnings run rate than a year ago. With net profit margin now sitting higher than a year earlier, the story for investors centers on how firmly these margin gains can be held through the cycle.

With the headline numbers on the table, the next step is to set them against the main stories circulating around Amkor to see which narratives the results support and which they call into question.

Profit margin steps up to 6.2%

• Over the last 12 months, Amkor converted US$7.1b of revenue into US$436.1 million of net income, which works out to a 6.2% net margin compared with 5.0% a year earlier.
• Bulls argue that margin work is just getting started, and this recent 6.2% margin alongside trailing 12 month EPS of US$1.76 backs the idea that operating tweaks and mix shift toward higher value packaging could support stronger profitability. Yet the five year record of earnings declining 13.3% per year reminds you that turning short term gains into a long term pattern is not automatic.
  • Supporters point to trailing earnings growth of 37.9% over the last year and forecast earnings growth of about 18.3% per year as evidence that higher margin projects are already flowing through the income statement.
  • Set against that, the longer term decline in earnings and only 9% forecast revenue growth, below the 11.1% U.S. market revenue forecast, shows why some investors treat the recent margin level as a proof point that still needs time to season.

Bulls see these margin and earnings trends as a sign Amkor might be earlier in a profitability upswing than the headline numbers suggest, and they anchor that view in a fuller growth and cash flow story that goes well beyond Q1 2026 results 🐂 Amkor Technology Bull Case

One year earnings surge vs five year drag

• On a trailing basis, net income rose from US$316.2 million to US$436.1 million over the last year while the same earnings line averaged a 13.3% decline per year over five years, so the latest 37.9% one year growth rate looks very different to the longer record.
• Bears highlight this tension, arguing that the strong trailing 12 month earnings number and Q1 EPS of US$0.34 sit on top of a history where earnings did not grow consistently, and they question how durable the current run rate is if capex plans and industry shifts do not line up perfectly with demand.
  • Critics point to the five year earnings decline and the company’s focus on heavy investment in advanced packaging capacity as areas where any slowdown in orders could hit both utilization and profitability at the same time.
  • At the same time, the move from US$6.3b to US$7.1b in trailing revenue shows that the business is handling a larger top line, which could either support the bearish view of higher execution risk or, if margins hold, gradually blunt the historical earnings drag.

Skeptics focus on this clash between one year strength and five year pressure, and they lay out how shifts in manufacturing locations and customer behavior could matter for Amkor’s core packaging and test volumes 🐻 Amkor Technology Bear Case

P/E at 40.5x with a wide value gap

• At a current share price of US$71.36 and trailing EPS of US$1.76, Amkor trades on a P/E of 40.5x, which is lower than the U.S. Semiconductor industry at 49.2x and a peer average of 74.7x, while the stated DCF fair value of US$4.42 is far below the current price.
• What stands out to both bullish and bearish investors is how mixed this picture is, because the P/E discount against industry and peers can be read as a relative value signal at the same time as the very low DCF fair value raises questions about how different models are treating Amkor’s US$7.1b of trailing revenue and 6.2% margin.
  • Supportive investors tend to frame the 40.5x P/E as more reasonable given the 37.9% one year earnings increase and forecasts of roughly 18.3% annual earnings growth, especially when peer multiples are much higher.
  • More cautious investors focus on the gap between US$71.36 and the US$4.42 DCF fair value, using it as a reminder that some valuation methods embed far more conservative assumptions about how the recent earnings and margin profile might evolve over time.
