What happened

Amkor (AMKR) fell 6.3% on October 26, 2026, after it reported third-quarter results that missed per-share expectations while highlighting record sales in computing and automotive end markets. The company posted quarterly earnings of $0.76 per share against $0.78 expected, and revenue of $1.99 billion, with management noting increased contribution from advanced packaging products, according to Business Wire and Benzinga.

Closing price over the last 30 trading sessions. On October 26, 2026, AMKR closed at $36.81, down 6.3% on the day and 20.6% lower than 30 sessions earlier.

How big was the move

The stock closed at $36.81 after opening 1.6% below the previous close and traded at 5.5 times its 20-day average volume, signalling heavier-than-normal selling. The single-session change was 1.5 times a typical daily move for this stock, and it underperformed the Technology sector median by 6.8 percentage points on the day. Over the last five sessions the shares fell 12.1% while the S&P 500 rose 0.7% on October 26, 2026; the S&P 500 had fallen 0.2% over those five sessions.

Each bar is one day's price change; the outlined bar is October 26, 2026. A typical daily move over the past year was 5.0%, so the latest move equals 1.3 times that. Moves outside the dashed lines (about 9.9%) are unusual.

The technical picture

The stock traded well below its moving averages: the stock sat 22.1% below its 20-day moving average, 25.0% below its 50-day moving average, and 36.0% below its 200-day moving average. The 50-day average is below the 200-day average, a sign of a weak longer-term trend. The Relative Strength Index (14 days) stood at 27, below 30, a level often called oversold. The stock is 61.9% below its 52-week high and has fallen 31.3% over one month and 19.4% over three months; over one year it rose 15.1%, 1.2 percentage points ahead of the S&P 500. Volatility is elevated at 68% annualized over 60 days, higher than 78% of its own readings over five years, and the stock’s beta of 2.09 indicates it tends to move more than the market.

Closing price over the past year. AMKR ends the period 60.7% below its 52-week high, below its 50-day average ($49.07) and below its 200-day average ($57.48).

Fundamentals and valuation

On a trailing four-quarter basis through September 30, 2026, Amkor reported revenue of $7.46 billion, which grew 15.7% from a year earlier and followed quarter-on-quarter growth of 17.9% in the prior period. Gross margin improved to 16.6% from 13.5% a year earlier, and operating margin rose to 9.5% from 6.5%. Free-cash-flow margin stood at 14.5% and return on invested capital was 7.3%. The balance sheet shows net debt of 0.7 times EBITDA.

Quarterly revenue by period end. The latest quarter brought $2.0B, 0.2% more than the same quarter a year earlier.

Valuation measures point to a relatively inexpensive stock on cash metrics: the price to forward earnings was 14.2 times expected earnings and the free-cash-flow yield was 11.1%. PromtFinance scores place Amkor high for Value at 97 (Exceptional), neutral for Growth at 49 and Quality at 61, but weak on Momentum at 27 and Stability at 31. Those scores reflect a mix of strong cash generation and valuation metrics alongside recent share-price weakness and volatility.

Earnings and analyst expectations

Amkor’s report on October 26, 2026, showed quarterly earnings per share of $0.76, 2.9% below the Zacks Consensus Estimate of $0.78. The company cited record sales in computing and automotive and industrial markets and an increased contribution from advanced packaging products in the quarter. The company has zero consecutive quarters beating estimates, and the typical two-day market reaction after recent reports has been a fall of 1.0%; the average surprise over the last four reports is listed as 37.5% above estimates.

Diluted earnings per share by quarter. The latest quarter shows $0.70, against $0.22 in the same quarter a year earlier.

Analysts’ consensus rating is Buy, with 50% of the 14 analysts covering the stock assigning a Buy or Strong Buy. The consensus price target is $78.75, which is 113.9% above the closing price on October 26, 2026. That gap between the consensus target and the market price reflects analysts’ optimism about future earnings and the company’s valuation on cash metrics, even as momentum and recent results have put pressure on the share price.
