SemGroup (NYSE:SEMG) Seems To Be Using An Awful Lot Of Debt

Simply Wall St

Some say volatility, rather than debt, is the best way to think about risk as an investor, but Warren Buffett famously said that 'Volatility is far from synonymous with risk.' 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. Importantly, SemGroup Corporation (NYSE:SEMG) does carry debt. But is this debt a concern to shareholders?

When Is Debt A Problem?

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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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. 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.

How Healthy Is SemGroup's Balance Sheet?

We can see from the most recent balance sheet that SemGroup had liabilities of US$720.6m falling due within a year, and liabilities of US$2.79b due beyond that. Offsetting these obligations, it had cash of US$343.6m as well as receivables valued at US$781.5m due within 12 months. So it has liabilities totalling US$2.39b more than its cash and near-term receivables, combined.

The deficiency here weighs heavily on the US$779.9m company itself, as if a child were struggling under the weight of an enormous back-pack full of books, his sports gear, and a trumpet. So we definitely think shareholders need to watch this one closely. After all, SemGroup would likely require a major re-capitalisation if it had to pay its creditors today.

We use two main ratios to inform us about debt levels relative to earnings. The first is net debt divided by earnings before interest, tax, depreciation, and amortization (EBITDA), while the second is how many times its earnings before interest and tax (EBIT) covers its interest expense (or its interest cover, for short). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

SemGroup shareholders face the double whammy of a high net debt to EBITDA ratio (6.8), and fairly weak interest coverage, since EBIT is just 0.55 times the interest expense. The debt burden here is substantial. Even more troubling is the fact that SemGroup actually let its EBIT decrease by 4.8% over the last year. If that earnings trend continues the company will face an uphill battle to pay off its debt. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine SemGroup's ability to maintain a healthy balance sheet going forward.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. During the last three years, SemGroup burned a lot of cash. 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 SemGroup's conversion of EBIT to free cash flow and its track record of staying on top of its total liabilities make us rather uncomfortable with its debt levels. And even its net debt to EBITDA fails to inspire much confidence. We think the chances that SemGroup has too much debt a very significant. To our minds, that means the stock is rather high risk, and probably one to avoid; but to each their own (investing) style. Given the risks around SemGroup's use of debt, the sensible thing to do is to check if insiders have been unloading the stock.
