There's no doubt that money can be made by owning shares of unprofitable businesses. By way of example, Surge Copper (CVE:SURG) has seen its share price rise 268% over the last year, delighting many shareholders. But while history lauds those rare successes, those that fail are often forgotten; who remembers Pets.com?
In light of its strong share price run, we think now is a good time to investigate how risky Surge Copper's cash burn is. In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. First, we'll determine its cash runway by comparing its cash burn with its cash reserves.
You can calculate a company's cash runway by dividing the amount of cash it has by the rate at which it is spending that cash. In June 2026, Surge Copper had CA$21m in cash, and was debt-free. In the last year, its cash burn was CA$11m. That means it had a cash runway of around 22 months as of June 2026. While that cash runway isn't too concerning, sensible holders would be peering into the distance, and considering what happens if the company runs out of cash. You can see how its cash balance has changed over time in the image below.

Surge Copper 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. In fact, it ramped its spending strongly over the last year, increasing cash burn by 108%. That sort of spending growth rate can't continue for very long before it causes balance sheet weakness, generally speaking. Surge Copper makes us a little nervous due to its lack of substantial operating revenue. So we'd generally prefer stocks from this list of stocks that have analysts forecasting growth.
While Surge Copper 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. 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 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 CA$244m, Surge Copper's CA$11m in cash burn equates to about 4.7% of its market value. That's a low proportion, so we figure the company would be able to raise more cash to fund growth, with a little dilution, or even to simply borrow some money.
On this analysis of Surge Copper's cash burn, we think its cash burn relative to its market cap was reassuring, while its increasing cash burn has us a bit worried. While we're the kind of investors who are always a bit concerned about the risks involved with cash burning companies, the metrics we have discussed in this article leave us relatively comfortable about Surge Copper's situation.
