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 software-as-a-service business Salesforce.com lost money for years while it grew recurring revenue, if you held shares since 2005, you'd have done very well indeed. But the harsh reality is that very many loss making companies burn through all their cash and go bankrupt.

So, the natural question for Generation Bio (NASDAQ:GBIO) shareholders is whether they should be concerned by its rate of cash burn. For the purpose of this article, we'll define cash burn as the amount of cash the company is spending each year to fund its growth (also called its negative free cash flow). First, we'll determine its cash runway by comparing its cash burn with its cash reserves.

Does Generation Bio Have A Long Cash Runway?

A cash runway is defined as the length of time it would take a company to run out of money if it kept spending at its current rate of cash burn. In March 2021, Generation Bio had US$451m in cash, and was debt-free. Importantly, its cash burn was US$80m over the trailing twelve months. That means it had a cash runway of about 5.7 years as of March 2021. Even though this is but one measure of the company's cash burn, the thought of such a long cash runway warms our bellies in a comforting way. You can see how its cash balance has changed over time in the image below.

How Is Generation Bio's Cash Burn Changing Over Time?

Generation Bio didn't record any revenue over the last year, indicating that it's an early stage company still developing its business. Nonetheless, we can still examine its cash burn trajectory as part of our assessment of its cash burn situation. Over the last year its cash burn actually increased by 28%, which suggests that management are increasing investment in future growth, but not too quickly. However, the company's true cash runway will therefore be shorter than suggested above, if spending continues to increase. 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 Generation Bio Raise Cash?

Given its cash burn trajectory, Generation Bio shareholders may wish to consider how easily it could raise more cash, despite its solid cash runway. Companies can raise capital through either debt or equity. Commonly, a business will sell new shares in itself to raise cash and drive 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.

Generation Bio's cash burn of US$80m is about 5.8% of its US$1.4b market capitalisation. That's a low proportion, so we figure the company would be able to raise more cash to fund growth, with a little dilution, or even to simply borrow some money.

Is Generation Bio's Cash Burn A Worry?

As you can probably tell by now, we're not too worried about Generation Bio's 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.
