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. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.

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

Does NextSource Materials Have A Long Cash Runway?

A company's cash runway is the amount of time it would take to burn through its cash reserves at its current cash burn rate. As at March 2024, NextSource Materials had cash of US$19m and no debt. Importantly, its cash burn was US$18m over the trailing twelve months. So it had a cash runway of approximately 13 months from March 2024. 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. Depicted below, you can see how its cash holdings have changed over time.

How Is NextSource Materials' Cash Burn Changing Over Time?

NextSource Materials 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. As it happens, the company's cash burn reduced by 17% over the last year, which suggests that management are maintaining a fairly steady rate of business development, albeit with a slight decrease in spending. 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.

How Hard Would It Be For NextSource Materials To Raise More Cash For Growth?

Even though it has reduced its cash burn recently, shareholders should still consider how easy it would be for NextSource Materials to raise more cash in the future. 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 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).

NextSource Materials has a market capitalisation of US$74m and burnt through US$18m last year, which is 24% 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 NextSource Materials' Cash Burn?

Even though its cash burn relative to its market cap makes us a little nervous, we are compelled to mention that we thought NextSource Materials' cash burn reduction was relatively promising. Even though we don't think it has a problem with its cash burn, the analysis we've done in this article does suggest that shareholders should give some careful thought to the potential cost of raising more money in the future.
