Even when a business is losing money, it's possible for shareholders to make money if they buy a good business at the right price. 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. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.

So, the natural question forReWalk Robotics(NASDAQ:RWLK) shareholders is whether they should be concerned by its rate of cash burn. In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

We reckon the fact that ReWalk Robotics managed to shrink its cash burn by 21% over the last year is rather encouraging. But the revenue dip of 2.6% in the same period was a bit concerning. On balance, we'd say the company is improving over time. While the past is always worth studying, it is the future that matters most of all. 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 ReWalk Robotics Raise Cash?

We are certainly impressed with the progress ReWalk Robotics has made over the last year, but it is also worth considering how costly it would be if it wanted to raise more cash to fund faster growth. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. 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.

ReWalk Robotics has a market capitalisation of US$65m and burnt through US$11m last year, which is 18% of the company's market value. As a result, we'd venture that the company could raise more cash for growth without much trouble, albeit at the cost of some dilution.How Risky Is ReWalk Robotics' Cash Burn Situation?
