Is Westlake (NYSE:WLK) Using Too Much Debt?

Howard Marks put it nicely when he said that, rather than worrying about share price volatility, 'The possibility of permanent loss is the risk I worry about... and every practical investor I know worries about.' 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. Importantly, Westlake Corporation (NYSE:WLK) does carry debt. But the real question is whether this debt is making the company risky.

When Is Debt Dangerous?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. However, a more common (but still painful) scenario is that it has to raise new equity capital at a low price, thus permanently diluting shareholders. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. When we think about a company's use of debt, we first look at cash and debt together.

What Is Westlake's Net Debt?

As you can see below, Westlake had US$4.89b of debt, at June 2024, which is about the same as the year before. You can click the chart for greater detail. On the flip side, it has US$3.04b in cash leading to net debt of about US$1.84b.

How Strong Is Westlake's Balance Sheet?

The latest balance sheet data shows that Westlake had liabilities of US$2.54b due within a year, and liabilities of US$7.45b falling due after that. On the other hand, it had cash of US$3.04b and US$1.81b worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$5.14b.

While this might seem like a lot, it is not so bad since Westlake has a huge market capitalization of US$17.6b, and so it could probably strengthen its balance sheet by raising capital if it needed to. But it's clear that we should definitely closely examine whether it can manage its debt without dilution.

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). The advantage of this approach is that we take into account both the absolute quantum of debt (with net debt to EBITDA) and the actual interest expenses associated with that debt (with its interest cover ratio).

Westlake's net debt is only 0.97 times its EBITDA. And its EBIT covers its interest expense a whopping 16.1 times over. So you could argue it is no more threatened by its debt than an elephant is by a mouse. In fact Westlake's saving grace is its low debt levels, because its EBIT has tanked 47% in the last twelve months. Falling earnings (if the trend continues) could eventually make even modest debt quite risky. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately the future profitability of the business will decide if Westlake can strengthen its balance sheet over time. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the most recent three years, Westlake recorded free cash flow worth 69% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This free cash flow puts the company in a good position to pay down debt, when appropriate.

Our View

Westlake's EBIT growth rate was a real negative on this analysis, although the other factors we considered were considerably better. There's no doubt that its ability to to cover its interest expense with its EBIT is pretty flash. When we consider all the factors mentioned above, we do feel a bit cautious about Westlake's use of debt. While debt does have its upside in higher potential returns, we think shareholders should definitely consider how debt levels might make the stock more risky. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately, every company can contain risks that exist outside of the balance sheet. To that end, you should be aware of the 2 warning signs we've spotted with Westlake .
