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. Nonetheless, only a fool would ignore the risk that a loss making company burns through its cash too quickly.

Given this risk, we thought we'd take a look at whether Larimar Therapeutics (NASDAQ:LRMR) shareholders should 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). The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

Does Larimar Therapeutics 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 September 2024, Larimar Therapeutics had US$204m in cash, and was debt-free. Importantly, its cash burn was US$59m over the trailing twelve months. Therefore, from September 2024 it had 3.5 years of cash runway. A runway of this length affords the company the time and space it needs to develop the business. The image below shows how its cash balance has been changing over the last few years.

How Is Larimar Therapeutics' Cash Burn Changing Over Time?

Larimar Therapeutics 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 a very significant 91%. 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. 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 Larimar Therapeutics Raise Cash?

Given its cash burn trajectory, Larimar Therapeutics shareholders may wish to consider how easily it could raise more cash, despite its solid cash runway. 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. 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.

Larimar Therapeutics' cash burn of US$59m is about 15% of its US$394m market capitalisation. 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.

So, Should We Worry About Larimar Therapeutics' Cash Burn?

It may already be apparent to you that we're relatively comfortable with the way Larimar Therapeutics is burning through its cash. For example, we think its cash runway suggests that the company is on a good path. Although we do find its increasing cash burn to be a bit of a negative, once we consider the other metrics mentioned in this article together, the overall picture is one we are comfortable with. 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.
