There's no doubt that money can be made by owning shares of unprofitable businesses. For example, although Amazon.com made losses for many years after listing, if you had bought and held the shares since 1999, you would have made a fortune. But the harsh reality is that very many loss making companies burn through all their cash and go bankrupt.

So should Kezar Life Sciences (NASDAQ:KZR) shareholders be worried about its cash burn? In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. Let's start with an examination of the business' cash, relative to its cash burn.

Does Kezar Life Sciences Have A Long Cash Runway?

A company's cash runway is the amount of time it would take to burn through its cash reserves at its current cash burn rate. In December 2020, Kezar Life Sciences had US$140m in cash, and was debt-free. In the last year, its cash burn was US$37m. That means it had a cash runway of about 3.8 years as of December 2020. There's no doubt that this is a reassuringly long runway. You can see how its cash balance has changed over time in the image below.

How Is Kezar Life Sciences' Cash Burn Changing Over Time?

Kezar Life Sciences didn't record any revenue over the last year, indicating that it's an early stage company still developing its business. So while we can't look to sales to understand growth, we can look at how the cash burn is changing to understand how expenditure is trending over time. With the cash burn rate up 22% in the last year, it seems that the company is ratcheting up investment in the business over time. That's not necessarily a bad thing, but investors should be mindful of the fact that will shorten the cash runway. Clearly, however, the crucial factor is whether the company will grow its business going forward. So you might want to take a peek at how much the company is expected to grow in the next few years.

How Easily Can Kezar Life Sciences Raise Cash?

While Kezar Life Sciences does have a solid cash runway, its cash burn trajectory may have some shareholders thinking ahead to when the company may need to raise more cash. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. Many companies end up issuing new shares to fund future growth. We can compare a company's cash burn to its market capitalisation to get a sense for how many new shares a company would have to issue to fund one year's operations.

Since it has a market capitalisation of US$253m, Kezar Life Sciences' US$37m in cash burn equates to about 15% of its market value. Given that situation, it's fair to say the company wouldn't have much trouble raising more cash for growth, but shareholders would be somewhat diluted.

How Risky Is Kezar Life Sciences' Cash Burn Situation?

As you can probably tell by now, we're not too worried about Kezar Life Sciences' cash burn. In particular, we think its cash runway stands out as evidence that the company is well on top of its spending. Although its increasing cash burn does give us reason for pause, the other metrics we discussed in this article form a positive picture overall. Based on the factors mentioned in this article, we think its cash burn situation warrants some attention from shareholders, but we don't think they should be worried.
