Amkor Technology (AMKR) just posted third quarter 2026 results, reporting sales of about US$2.0b and net income of US$190.6m, along with fresh guidance and a recently completed share repurchase tranche.
Despite the solid third quarter headline numbers and fresh buyback activity, Amkor Technology’s share price has swung sharply lower. It has fallen 14.5% on the day, 26.0% over the past week and 42.9% across 30 days, as investors digest new guidance, a trimmed fair value estimate of US$66.00 and mixed sentiment around capital spending and Communications exposure. This comes even though total shareholder return over three and five years remains positive at 39.4% and 41.2% respectively.

Most Popular Narrative: 54% Undervalued

The narrative relies on a 12.54% discount rate and assumes Amkor Technology can support $10.2b in future annual revenue with an 8.25% profit margin. These inputs feed into the $66.00 fair value estimate. That view also leans on a future P/E of 27.78x, compared with a much lower multiple implied by the current share price after the recent decline.
Result: Fair Value of $66.00 (UNDERVALUED)
Still, heavy capital commitments in Arizona and other regions, along with ongoing Communications softness, could erode margins and challenge the bullish Amkor Technology narrative.

Another View: Cash Flows Paint A Harsher Picture
While the popular Amkor Technology narrative leans on earnings and a $66.00 fair value, the SWS DCF model points in the opposite direction. On that cash flow view, AMKR at $30.49 trades well above an estimated value of $4.32, which suggests far less potential upside and significantly more valuation risk. Which version of reality do you trust when the numbers clash this sharply?
