Amkor has been on fire lately. In the past six months alone, the company’s stock price has rocketed 77%, reaching $39.48 per share. This was partly thanks to its solid quarterly results, and the performance may have investors wondering how to approach the situation.

Why Is Amkor Not Exciting?
We’re glad investors have benefited from the price increase, but we're cautious about Amkor. Here are three reasons we avoid AMKR and a stock we'd rather own.
1. Low Gross Margin Reveals Weak Structural Profitability
In the semiconductor industry, a company’s gross profit margin is a critical metric to track because it sheds light on its pricing power, complexity of products, and ability to procure raw materials, equipment, and labor.
Amkor’s gross margin is one of the worst in the semiconductor industry, signaling it operates in a competitive market and lacks pricing power. As you can see below, it averaged a 14.2% gross margin over the last two years. That means Amkor paid its suppliers a lot of money ($85.75 for every $100 in revenue) to run its business.

2. EPS Growth Has Stalled
Analyzing the long-term change in earnings per share (EPS) shows whether a company's incremental sales were profitable – for example, revenue could be inflated through excessive spending on advertising and promotions.
Amkor’s flat EPS over the last five years was below its 5.8% annualized revenue growth. This tells us the company became less profitable on a per-share basis as it expanded.

3. Mediocre Free Cash Flow Margin Limits Reinvestment Potential
Free cash flow isn't a prominently featured metric in company financials and earnings releases, but we think it's telling because it accounts for all operating and capital expenses, making it tough to manipulate. Cash is king.
Amkor has shown poor cash profitability over the last two years, giving the company limited opportunities to return capital to shareholders. Its free cash flow margin averaged 5.1%, lousy for a semiconductor business.

Final Judgment
Amkor’s business quality ultimately falls short of our standards. Following the recent surge, the stock trades at 25.5× forward P/E (or $39.48 per share). Investors with a higher risk tolerance might like the company, but we think the potential downside is too great. We're fairly confident there are better stocks to buy right now.
