Warren Buffett famously said, 'Volatility is far from synonymous with risk.' 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. As with many other companies Lumen Technologies, Inc. (NYSE:LUMN) makes use of debt. But the more important question is: how much risk is that debt creating?

When Is Debt Dangerous?

Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. 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. The first step when considering a company's debt levels is to consider its cash and debt together.

How Much Debt Does Lumen Technologies Carry?

The image below, which you can click on for greater detail, shows that Lumen Technologies had debt of US$18.4b at the end of March 2024, a reduction from US$19.6b over a year. However, it also had US$1.58b in cash, and so its net debt is US$16.8b.

A Look At Lumen Technologies' Liabilities

According to the last reported balance sheet, Lumen Technologies had liabilities of US$3.82b due within 12 months, and liabilities of US$28.9b due beyond 12 months. On the other hand, it had cash of US$1.58b and US$1.37b worth of receivables due within a year. So it has liabilities totalling US$29.7b more than its cash and near-term receivables, combined.

The deficiency here weighs heavily on the US$1.25b 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'd watch its balance sheet closely, without a doubt. At the end of the day, Lumen Technologies would probably need a major re-capitalization if its creditors were to demand repayment.

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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

While we wouldn't worry about Lumen Technologies's net debt to EBITDA ratio of 4.5, we think its super-low interest cover of 0.69 times is a sign of high leverage. In large part that's due to the company's significant depreciation and amortisation charges, which arguably mean its EBITDA is a very generous measure of earnings, and its debt may be more of a burden than it first appears. So shareholders should probably be aware that interest expenses appear to have really impacted the business lately. Worse, Lumen Technologies's EBIT was down 72% over the last year. If earnings keep going like that over the long term, it has a snowball's chance in hell of paying off that debt. 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 Lumen Technologies can strengthen its balance sheet over time.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So we always check how much of that EBIT is translated into free cash flow. Over the most recent three years, Lumen Technologies recorded free cash flow worth 53% 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

On the face of it, Lumen Technologies's EBIT growth rate left us tentative about the stock, and its level of total liabilities was no more enticing than the one empty restaurant on the busiest night of the year. But on the bright side, its conversion of EBIT to free cash flow is a good sign, and makes us more optimistic. After considering the datapoints discussed, we think Lumen Technologies has too much debt. While some investors love that sort of risky play, it's certainly not our cup of tea. Given our concerns about Lumen Technologies's debt levels, it seems only prudent to check if insiders have been ditching the stock.
