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. But while the successes are well known, investors should not ignore the very many unprofitable companies that simply burn through all their cash and collapse.

So should Mirum Pharmaceuticals (NASDAQ:MIRM) shareholders be worried about its 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). We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

Does Mirum Pharmaceuticals 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. When Mirum Pharmaceuticals last reported its balance sheet in March 2021, it had zero debt and cash worth US$213m. Importantly, its cash burn was US$96m over the trailing twelve months. That means it had a cash runway of about 2.2 years as of March 2021. Notably, analysts forecast that Mirum Pharmaceuticals will break even (at a free cash flow level) in about 3 years. Essentially, that means the company will either reduce its cash burn, or else require more cash. You can see how its cash balance has changed over time in the image below.

How Is Mirum Pharmaceuticals' Cash Burn Changing Over Time?

Mirum Pharmaceuticals 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. Over the last year its cash burn actually increased by a very significant 73%. Oftentimes, increased cash burn simply means a company is accelerating its business development, but one should always be mindful that this causes the cash runway to shrink. 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.

Can Mirum Pharmaceuticals Raise More Cash Easily?

Given its cash burn trajectory, Mirum Pharmaceuticals 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. One of the main advantages held by publicly listed companies is that they can sell shares to investors to raise cash and fund growth. By looking at a company's cash burn relative to its market capitalisation, we gain insight on how much shareholders would be diluted if the company needed to raise enough cash to cover another year's cash burn.

Mirum Pharmaceuticals' cash burn of US$96m is about 18% of its US$536m market capitalisation. 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.
