We can readily understand why investors are attracted to unprofitable companies. 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 should Tamboran Resources (ASX:TBN) shareholders be worried about its cash burn? In this article, we define cash burn as its annual (negative) free cash flow, which is the amount of money a company spends each year to fund its growth. Let's start with an examination of the business' cash, relative to its cash burn.

How Long Is Tamboran Resources' Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. As at December 2024, Tamboran Resources had cash of US$59m and no debt. Looking at the last year, the company burnt through US$95m. That means it had a cash runway of around 7 months as of December 2024. Notably, analysts forecast that Tamboran Resources will break even (at a free cash flow level) in about 4 years. That means unless the company reduces its cash burn quickly, it may well look to raise more cash. You can see how its cash balance has changed over time in the image below.

How Is Tamboran Resources' Cash Burn Changing Over Time?

Tamboran Resources 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 25%, 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. 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 Tamboran Resources Raise More Cash Easily?

Since its cash burn is moving in the wrong direction, Tamboran Resources shareholders may wish to think ahead to when the company may need to raise more cash. Companies can raise capital through either debt or equity. Commonly, a business will sell new shares in itself to raise cash and drive 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.

Tamboran Resources has a market capitalisation of US$335m and burnt through US$95m last year, which is 28% of the company's market value. That's fairly notable cash burn, so if the company had to sell shares to cover the cost of another year's operations, shareholders would suffer some costly dilution.

So, Should We Worry About Tamboran Resources' Cash Burn?

Tamboran Resources is not in a great position when it comes to its cash burn situation. Although we can understand if some shareholders find its increasing cash burn acceptable, we can't ignore the fact that we consider its cash runway to be downright troublesome. One real positive is that analysts are forecasting that the company will reach breakeven. After looking at that range of measures, we think shareholders should be extremely attentive to how the company is using its cash, as the cash burn makes us uncomfortable.
