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

So, the natural question for Rock Tech Lithium (CVE:RCK) 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 Rock Tech Lithium Run Out Of Money?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. As at December 2022, Rock Tech Lithium had cash of CA$35m and no debt. Importantly, its cash burn was CA$68m over the trailing twelve months. That means it had a cash runway of around 6 months as of December 2022. That's quite a short cash runway, indicating the company must either reduce its annual cash burn or replenish its cash. The image below shows how its cash balance has been changing over the last few years.

How Is Rock Tech Lithium's Cash Burn Changing Over Time?

Rock Tech Lithium 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. Remarkably, it actually increased its cash burn by 287% in the last year. Given that sharp increase in spending, the company's cash runway will shrink rapidly as it depletes its cash reserves. While the past is always worth studying, it is the future that matters most of all. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.

How Easily Can Rock Tech Lithium Raise Cash?

Given its cash burn trajectory, Rock Tech Lithium shareholders should already be thinking about how easy it might be for it to raise further cash in the future. 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.

Rock Tech Lithium's cash burn of CA$68m is about 31% of its CA$220m market capitalisation. 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.

So, Should We Worry About Rock Tech Lithium's Cash Burn?

As you can probably tell by now, we're rather concerned about Rock Tech Lithium's cash burn. Take, for example, its increasing cash burn, which suggests the company may have difficulty funding itself, in the future. While not as bad as its increasing cash burn, its cash burn relative to its market cap is also a concern, and considering everything mentioned above, we're struggling to find much to be optimistic about. Once we consider the metrics mentioned in this article together, we're left with very little confidence in the company's ability to manage its cash burn, and we think it will probably need more money. Separately, we looked at different risks affecting the company and spotted 5 warning signs for Rock Tech Lithium (of which 3 are significant!) you should know about.
