Amkor Q3 Earnings Call Highlights Ai Growth And Capacity Expansion

Amkor Technology, Inc. AMKR emphasized accelerating demand for advanced semiconductor packaging, particularly in artificial intelligence and data center applications, during its third-quarter 2026 earnings call. Management highlighted expanding customer commitments and investments in manufacturing capacity.

Despite stronger computing demand and margin expansion, weakness in smartphone-related businesses remains a challenge. Executives outlined their expectations for the fourth quarter and discussed capital spending, pricing and capacity utilization.

Third-quarter earnings of 76 cents per share missed the Zacks Consensus Estimate of 79 cents. Revenues of $1.99 billion also fell short of the consensus mark of $2.02 billion.

Amkor's Computing Business Gains Momentum

CEO Kevin Engel highlighted record Computing revenues, which increased 25% sequentially and 37% year over year. Growth reflected the continued ramp of Amkor's flagship high-density fan-out (“HDFO”) CPU program and additional data center demand.

A hyperscaler's HDFO CPU program began ramping during the quarter. Two additional 2.5D packaging programs targeting networking and data centers are scheduled to begin production in the fourth quarter.

Engel expects Computing revenues to grow more than 30% in 2026, with a similar or higher growth rate anticipated in 2027. Data center demand continues to offset softness in personal computers.

AMKR Faces Continued Smartphone Weakness

CFO Megan Faust said Communications revenues declined 8% sequentially, reflecting memory supply constraints, changing production schedules and the migration of system-in-package (SiP) manufacturing to Vietnam.

Component shortages also affected premium smartphones and wearable devices. Management expects Communications revenues to decline a high-single-digit percentage sequentially in the fourth quarter.

Consumer revenues increased 10% sequentially, supported by IoT and home electronics demand. However, Faust expects a mid-teens sequential decline in the fourth quarter as component shortages persist.

Amkor Sees Further Margin Expansion

Gross margin reached 18.3%, expanding 150 basis points sequentially and 400 basis points year over year. Faust attributed the improvement primarily to a richer mix of advanced packaging products.

Foreign exchange pressures and an earthquake-related disruption at the Kumamoto, Japan, facility reduced sequential gross margin by approximately 60 basis points combined. Operations subsequently returned to normal.

During the analyst discussion, Faust indicated that Computing growth should support further margin improvement despite continued currency headwinds. Management expects fourth-quarter gross margin between 18% and 19%.

AMKR Accelerates Global Capacity Investments

Engel outlined significant expansion plans across Arizona, South Korea and Vietnam. Amkor's two-phase Arizona campus represents an estimated $12 billion investment, with Phase 1 construction scheduled for completion by year-end 2027.

In South Korea, additional facilities will support advanced packaging demand, including programs associated with NVIDIA. Vietnam's expansion will accommodate SiP production, freeing Korean manufacturing space for higher-value applications.

Faust expects 2026 capital expenditures of approximately $2.5 billion, followed by increased spending in 2027. Management anticipates elevated investment through 2028 and 2029 as Arizona construction and equipment deployment overlap.

Amkor Highlights Customer Funding and Pricing

Management emphasized longer-term customer commitments as a key development supporting capacity expansion. Faust disclosed that approximately a dozen customers have entered advance-payment arrangements since 2025.

During questions from BofA Securities, Engel explained that these agreements improve investment visibility and reduce capacity-related risks. Engel also emphasized equipment flexibility across advanced packaging technologies.

Responding to questions from UBS and Fox Advisors, Engel described a favorable pricing environment, supported by limited advanced packaging capacity. Engel indicated that customers recognize the substantial investment required to secure production capacity.

AMKR Outlines Q4 Expectations

Management expects fourth-quarter revenues between $1.9 billion and $2 billion. The company projects earnings between 65 cents and 75 cents per share. 

Faust expects Computing revenues to increase by low double digits sequentially, while Automotive and Industrial revenues should grow by low single digits. These gains will partially offset Communications and Consumer weakness.

Amkor Maintains Focus on Advanced Packaging

Management's overarching message centered on expanding advanced packaging capacity while maintaining disciplined investment and improving profitability.

Engel emphasized deeper customer relationships, growing AI infrastructure requirements and geographic diversification as priorities. Near-term consumer electronics weakness remains a counterweight to stronger data center demand.
