We Think Siltronic (ETR:WAF) Is Taking Some Risk With Its Debt

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.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. We note that Siltronic AG (ETR:WAF) does have debt on its balance sheet. But the real question is whether this debt is making the company risky.

What Risk Does Debt Bring?

Generally speaking, debt only becomes a real problem when a company can't easily pay it off, either by raising capital or with its own cash flow. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. However, a more usual (but still expensive) situation is where a company must dilute shareholders at a cheap share price simply to get debt under control. Of course, the upside of debt is that it often represents cheap capital, especially when it replaces dilution in a company with the ability to reinvest at high rates of return. When we think about a company's use of debt, we first look at cash and debt together.

What Is Siltronic's Debt?

You can click the graphic below for the historical numbers, but it shows that as of June 2023 Siltronic had €655.8m of debt, an increase on €300.0m, over one year. However, because it has a cash reserve of €588.0m, its net debt is less, at about €67.8m.

How Healthy Is Siltronic's Balance Sheet?

Zooming in on the latest balance sheet data, we can see that Siltronic had liabilities of €519.8m due within 12 months and liabilities of €1.50b due beyond that. Offsetting these obligations, it had cash of €588.0m as well as receivables valued at €208.7m due within 12 months. So it has liabilities totalling €1.23b more than its cash and near-term receivables, combined.

This deficit isn't so bad because Siltronic is worth €2.40b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. However, it is still worthwhile taking a close look at its ability to pay off debt.

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.

Siltronic has a low debt to EBITDA ratio of only 0.13. But the really cool thing is that it actually managed to receive more interest than it paid, over the last year. So it's fair to say it can handle debt like a hotshot teppanyaki chef handles cooking. But the bad news is that Siltronic has seen its EBIT plunge 17% in the last twelve months. We think hat kind of performance, if repeated frequently, could well lead to difficulties for the stock. There's no doubt that we learn most about debt from the balance sheet. But ultimately the future profitability of the business will decide if Siltronic can strengthen its balance sheet over time.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. Over the last three years, Siltronic saw substantial negative free cash flow, in total. While investors are no doubt expecting a reversal of that situation in due course, it clearly does mean its use of debt is more risky.

Our View

To be frank both Siltronic's EBIT growth rate and its track record of converting EBIT to free cash flow make us rather uncomfortable with its debt levels. But on the bright side, its interest cover is a good sign, and makes us more optimistic. Once we consider all the factors above, together, it seems to us that Siltronic's debt is making it a bit risky. That's not necessarily a bad thing, but we'd generally feel more comfortable with less leverage. When analysing debt levels, the balance sheet is the obvious place to start. However, not all investment risk resides within the balance sheet - far from it. These risks can be hard to spot. Every company has them, and we've spotted 3 warning signs for Siltronic (of which 2 are concerning!) you should know about.
