Just because a business does not make any money, does not mean that the stock will go down. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. But while history lauds those rare successes, those that fail are often forgotten; who remembers Pets.com?
So, the natural question for Larimar Therapeutics (NASDAQ:LRMR) shareholders is whether they should be concerned by its rate of cash burn. For the purposes of this article, cash burn is the annual rate at which an unprofitable company spends cash to fund its growth; its negative free cash flow. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.
When Might Larimar Therapeutics Run Out Of Money?
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 Larimar Therapeutics last reported its June 2026 balance sheet in August 2026, it had zero debt and cash worth US$156m. Looking at the last year, the company burnt through US$156m. So it had a cash runway of approximately 12 months from June 2026. That's not too bad, but it's fair to say the end of the cash runway is in sight, unless cash burn reduces drastically. However, if we extrapolate the company's recent cash burn trend, then it would have a longer cash run way. 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. During the last twelve months, its cash burn actually ramped up 69%. While this spending increase is no doubt intended to drive growth, if the trend continues the company's cash runway will shrink very quickly. Clearly, however, the crucial factor is whether the company will grow its business going forward. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.
How Hard Would It Be For Larimar Therapeutics To Raise More Cash For Growth?
While Larimar Therapeutics 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. 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 comparing a company's annual cash burn to its total market capitalisation, we can estimate roughly how many shares it would have to issue in order to run the company for another year (at the same burn rate).
Since it has a market capitalisation of US$403m, Larimar Therapeutics' US$156m in cash burn equates to about 39% of its market value. That's not insignificant, and if the company had to sell enough shares to fund another year's growth at the current share price, you'd likely witness fairly costly dilution.
Is Larimar Therapeutics' Cash Burn A Worry?
On this analysis of Larimar Therapeutics' cash burn, we think its cash runway was reassuring, while its increasing cash burn has us a bit worried. Looking at the factors mentioned in this short report, we do think that its cash burn is a bit risky, and it does make us slightly nervous about the stock.
