Amkor Technology Stock Plummets on Weak Third-Quarter Revenue Forecast

Summary
Shares of the semiconductor packaging firm fell more than 22% after it issued third-quarter revenue guidance that fell significantly short of analyst expectations, citing manufacturing shifts and weak memory demand.
Amkor Technology (NASDAQ: AMKR) shares plunged in morning trading after the semiconductor packaging and test services company issued a third-quarter revenue forecast that widely missed Wall Street estimates, overshadowing a record second-quarter performance.
The stock fell 22.9% from its prior close of $60.71, a sharp decline driven almost entirely by the company's forward-looking guidance rather than its past results.
Guidance Misses Expectations
Amkor announced that it anticipates third-quarter revenue to be in the range of $1.95 billion to $2.05 billion. This projection falls well below the analyst consensus estimate of approximately $2.12 billion, signaling a significant deceleration for the company.
The disappointing outlook came despite a strong second quarter in which Amkor reportedly beat expectations on both revenue and earnings per share. However, investors focused heavily on the future headwinds highlighted by management.
Key Headwinds Identified
AdThe company attributed the weak Q3 forecast to two primary factors:
- Manufacturing Transition: A projected decline in communications revenue is tied to the ongoing migration of its system-in-package (SiP) manufacturing from South Korea to Vietnam. Management indicated this transition would weigh on financial results through the fourth quarter and into early 2027.
- Memory Market Softness: Amkor also cited continued weakness in demand related to the memory market as a contributing factor to the lower-than-expected guidance.
Analyst and Market Reaction
In response to the report, B. Riley cut its price target on Amkor stock to $65 from $75, though it maintained a Neutral rating. The negative sentiment was compounded by recent insider selling activity, with the source noting 20 open-market sales and zero purchases over the last six months.
The broader market provided little support, with the NASDAQ Composite down 0.7%. However, with the S&P 500 flat, the significant drop in Amkor's stock was clearly driven by company-specific news rather than macroeconomic pressures.
