If You Invested $1000 In Amkor Technology 10 Years Ago, This Is How Much You'd Have Now

For most investors, how much a stock's price changes over time is important. This factor can impact your investment portfolio as well as help you compare investment results across sectors and industries.

FOMO, or the fear of missing out, also plays a role in investing, particularly with tech giants and popular consumer-facing stocks.

What if you'd invested in Amkor Technology (AMKR) ten years ago? It may not have been easy to hold on to AMKR for all that time, but if you did, how much would your investment be worth today?

Amkor Technology's Business In-Depth

With that in mind, let's take a look at Amkor Technology's main business drivers.

Amkor Technology is a leading outsourced semiconductor assembly and test service provider (OSAT). The company packages and tests integrated circuits for customers across smartphones, data centers, artificial intelligence (AI), automotive, industrial and consumer devices. Its services span package design, wafer bump and probe, wafer back-grind, packaging, burn-in, system-level and final test and drop shipment. Amkor offers advanced packaging technologies, including High-Density Fan-Out (HDFO), 2.5D integration, advanced flip chip, fine pitch bumping, wafer-level processing and system-in-package solutions. 

Tempe, AZ-based Amkor serves integrated device manufacturers, fabless semiconductor companies, original equipment manufacturers and contract foundries. For 2025, net sales stood at $6.71 billion, up 6.2% from 2024. Packaging represented 89% of sales, and test services accounted for 11%. By end market in 2025, communications (including smartphones and tablets) represented 46% of sales; computing (including data center, infrastructure, PC/laptop and storage) accounted for 20%; automotive, industrial and other (including ADAS, electrification, infotainment and safety) contributed 19%; and consumer (including AR and gaming, connected home, home electronics and wearables) comprised 15%. 

In 2025, sales from the United States accounted for 65.6% of sales. Europe, Middle East and Africa contributed 12.7% while Asia Pacific, excluding Japan, contributed 10.9% of sales. Japan contributed 10.8% of total revenues. The top 10 customers collectively represented 72% of 2025 sales. 

Amkor operates a broad manufacturing footprint across Asia and Europe, including facilities in China, Japan, Korea, Malaysia, the Philippines, Portugal, Taiwan and Vietnam. The Vietnam facility opened in 2024 and continued to scale production in 2025. The company began construction of a new advanced packaging and test facility in Arizona in the second half of 2025, with the first phase planned at approximately 1.8 million square feet and manufacturing expected to begin in the first half of 2028.

Bottom Line

While anyone can invest, building a lucrative investment portfolio takes research, patience, and a little bit of risk. If you had invested in Amkor Technology ten years ago, you're probably feeling pretty good about your investment today.

A $1000 investment made in May 2016 would be worth $13,691.49, or a 1,269.15% gain, as of May 7, 2026, according to our calculations. Investors should note that this return excludes dividends but includes price increases.

Compare this to the S&P 500's rally of 258.03% and gold's return of 249.86% over the same time frame.

Looking ahead, analysts are expecting more upside for AMKR.

Amkor Technology reported first-quarter 2026 earnings of 33 cents per share, beating estimates by 43.48%, while revenues of $1.68 billion rose 27.5% year over year and surpassed consensus by 1.97%. Communications surged 42%, automotive and industrial rose 28% and computing grew 19% year over year, with record AI datacenter revenue and advanced products totaling $1.37 billion, up 28.9%. Gross margin expanded 230 basis points to 14.2% and operating margin improved 360 basis points to 6.0%. However, PC demand remained soft, material supply constraints are estimated at $50–$100 million per quarter, and capex of $2.5–$3.0 billion will pressure free cash flow. Q2 revenues are guided to $1.75–$1.85 billion with gross margin of 14.5%–15.5% and EPS of 42–52 cents, as a key HDFO datacenter CPU ramp gets underway.

The stock is up 47.31% over the past four weeks, and no earnings estimate has gone lower in the past two months, compared to 3 higher, for fiscal 2026. The consensus estimate has moved up as well.
