Is Amkor Technology (NASDAQ:AMKR) A Risky Investment?

Simply Wall St

The external fund manager backed by Berkshire Hathaway's Charlie Munger, Li Lu, makes no bones about it when he says 'The biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital.' When we think about how risky a company is, we always like to look at its use of debt, since debt overload can lead to ruin. We note that Amkor Technology, Inc. (NASDAQ:AMKR) does have debt on its balance sheet. But the more important question is: how much risk is that debt creating?

When Is Debt Dangerous?

Debt is a tool to help businesses grow, but if a business is incapable of paying off its lenders, then it exists at their mercy. If things get really bad, the lenders can take control of the business. However, a more frequent (but still costly) occurrence is where a company must issue shares at bargain-basement prices, permanently diluting shareholders, just to shore up its balance sheet. Of course, plenty of companies use debt to fund growth, without any negative consequences. When we examine debt levels, we first consider both cash and debt levels, together.

How Strong Is Amkor Technology's Balance Sheet?

According to the last reported balance sheet, Amkor Technology had liabilities of US$1.04b due within 12 months, and liabilities of US$1.44b due beyond 12 months. Offsetting this, it had US$551.4m in cash and US$702.5m in receivables that were due within 12 months. So its liabilities total US$1.22b more than the combination of its cash and short-term receivables.

While this might seem like a lot, it is not so bad since Amkor Technology has a market capitalization of US$2.34b, and so it could probably strengthen its balance sheet by raising capital if it needed to. But we definitely want to keep our eyes open to indications that its debt is bringing too much risk.

We measure a company's debt load relative to its earnings power by looking at its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and by calculating how easily its earnings before interest and tax (EBIT) cover its interest expense (interest cover). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

While Amkor Technology's low debt to EBITDA ratio of 0.95 suggests only modest use of debt, the fact that EBIT only covered the interest expense by 2.9 last year does give us pause. But the interest payments are certainly sufficient to have us thinking about how affordable its debt is. Shareholders should be aware that Amkor Technology's EBIT was down 31% last year. If that decline continues then paying off debt will be harder than selling foie gras at a vegan convention. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Amkor Technology's ability to maintain a healthy balance sheet going forward. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So it's worth checking how much of that EBIT is backed by free cash flow. In the last three years, Amkor Technology's free cash flow amounted to 29% of its EBIT, less than we'd expect. That's not great, when it comes to paying down debt.

Our View

We'd go so far as to say Amkor Technology's EBIT growth rate was disappointing. But at least it's pretty decent at managing its debt, based on its EBITDA,; that's encouraging. Overall, we think it's fair to say that Amkor Technology has enough debt that there are some real risks around the balance sheet. If all goes well, that should boost returns, but on the flip side, the risk of permanent capital loss is elevated by the debt. Given our hesitation about the stock, it would be good to know if Amkor Technology insiders have sold any shares recently. You click here to find out if insiders have sold recently.
