Amkor Q3 2026 Earnings Call: Record Computing Revenue, Margin Gains and a Heavy Capex Step-Up Ahead

Amkor reported $1.99 billion in Q3 revenue and an 18.3% gross margin as AI-driven Computing hit a record, while Communications weakened and management flagged higher 2027 capital spending funded in part by customer advance payments.

Amkor Technology (NASDAQ: AMKR) is in the news because its third-quarter 2026 earnings call, held on 26 October 2026, was summarised in a Nasdaq earnings-call highlights piece published on 27 October 2026. This article draws on the call transcript itself and presents the views expressed there, not our own.

Key takeaways

  • Third-quarter revenue was $1.99 billion, up 5% sequentially, with record revenue in both the Computing and the Automotive and Industrial end markets.
  • Gross margin reached 18.3%, up 150 basis points from the prior quarter and 400 basis points from a year earlier; operating margin was 11.3% and earnings per share were $0.76.
  • Communications and Consumer remain weak because of component shortages and the migration of SiP work to Vietnam, and management guided both lower again for the fourth quarter.
  • Customers are making long-term commitments and advance payments tied to future capacity. Management said a dozen customers have such arrangements, and that these will fund much of a step-up in capital spending in 2027.
  • Fourth-quarter guidance points to revenue of $1.9 billion to $2.0 billion and EPS of $0.65 to $0.75.

Bull case

  • CEO Kevin Engel said Computing and Automotive and Industrial revenue each grew 37% year on year, driven by the ramp of the flagship HDFO CPU program, a second hyperscaler CPU program that began ramping in Q3, and two new 2.5D programs due in Q4.
  • CFO Megan Faust attributed the margin expansion mainly to a richer mix of advanced packaging, and said Computing revenue rose 25% sequentially to a record. She expects Q4 revenue to be up more than 50% year on year.
  • Engel said Computing should grow more than 30% in 2026 and at a similar or higher rate in 2027, helped by new capacity in Korea.
  • Engel said customer advance payments and multi-year agreements improve visibility, and that customers are focused on securing capacity rather than on price. He described the pricing environment as one in which cost increases are typically passed on.
  • Faust said the balance sheet is solid through 2027, with $2.4 billion in cash and short-term investments, $3.4 billion in total liquidity and debt-to-EBITDA of 1.7x. She said advance payments may mean no incremental debt is needed through 2028, though it is too early to say.
  • Faust argued that a diversified portfolio cushions weakness in Communications and Consumer with strength in Computing.

Bear case

  • Communications revenue fell 8% sequentially, and Faust expects a high-single-digit decline in Q4. Consumer is expected to fall more than seasonally, into the mid-teens percent, because of the same component shortages.
  • Bank of America's Ruplu Bhattacharya noted that the Q4 gross margin guide implies only about 20 basis points of sequential improvement, and asked how SiP migration, Android weakness, currency and Japan would weigh on it. Faust cited unfavourable FX and lower SiP as continuing factors.
  • The Q4 net income guide of $160 million to $185 million is below Q3's $191 million, per the figures given on the call.
  • Morgan Stanley's Joe Moore observed that Computing grew 25% sequentially, below the roughly 30% discussed the previous quarter. Engel attributed this to the time needed to load the long HDFO process line, not to supply constraints.
  • Capital intensity is rising sharply. Faust said 2026 capex is about $2.5 billion, with a step-up in 2027 and Arizona spending peaking in 2028 and 2029. KeyBanc's Steve Barger and Needham's Denis Pyatchanin pressed on the funding and on how long elevated capex would last; Faust said no long-term normalised level has been given.
  • Engel acknowledged Arizona is expected to have higher costs from building depreciation and labour, though he said he does not expect a large margin difference over the long term.

What management said

  • Engel: "Our financial performance continues to strengthen." (closing remarks)
  • Engel, on packaging capacity: "packaging is becoming one of the key bottlenecks."
  • Engel, on computing: "We would expect a similar growth rate to even higher growth rate into 2027."
  • Faust, on the balance sheet: "the balance sheet positioning is solid through 2027."

Risks

  • Component and memory shortages and high memory prices, which management said have hurt premium smartphones, IoT wearables, PCs and low-tier Android phones.
  • Revenue and margin effects from moving SiP production from Korea to Vietnam, plus foreign-currency headwinds. The July earthquake at the Kumamoto facility cost about 60 basis points of gross margin together with FX; the site returned to full operations within the quarter.
  • Cost pressure on substrates and materials, which management said it is managing with suppliers and passing on to customers.
  • A concentrated customer exposure and the question, raised by Bank of America, of how fungible equipment is if a major AI program changes. Engel said the assets are fungible across high-density fan-out, 2.5D and wafer bumping and across customers.
  • Rising depreciation: Faust expects a mid-teens percent increase in 2026 and a further increase in 2027. The Arizona campus will not affect the income statement until it is completed at the end of 2027.
  • Uncertainty about the seasonality of Communications under changed phone launch cycles, which Engel called too early to call.

Outlook

  • Q4 2026: revenue of $1.9 billion to $2.0 billion, gross margin of 18% to 19%, operating expenses of about $140 million, net income of $160 million to $185 million and EPS of $0.65 to $0.75. The full-year effective tax rate is expected in the high teens.
  • By end market in Q4: Computing up low double digits sequentially, Automotive and Industrial up low single digits, Communications down high single digits, Consumer down into the mid-teens.
  • Capex: about $2.5 billion in 2026, narrowed on the timing of Arizona construction payments. Management indicated 2027 will step up, citing up to 15% of the $12 billion Arizona plan, $400 million to $450 million in Korea and about $50 million in Vietnam, together above $2 billion for facilities alone.
  • Not committed: specific 2027 capex guidance, which will come with the fourth-quarter call in February; the 2027 margin impact of added depreciation; whether incremental debt will be needed in 2028 or later; and a long-term normalised capex level.
