We can readily understand why investors are attracted to unprofitable companies. 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 Imugene (ASX:IMU) shareholders is whether they should be concerned by its rate of cash burn. In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

When Might Imugene Run Out Of Money?

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. When Imugene last reported its December 2023 balance sheet in February 2024, it had zero debt and cash worth AU$139m. In the last year, its cash burn was AU$73m. So it had a cash runway of approximately 23 months from December 2023. 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.

How Is Imugene's Cash Burn Changing Over Time?

While Imugene did record statutory revenue of AU$15m over the last year, it didn't have any revenue from operations. That means we consider it a pre-revenue business, and we will focus our growth analysis on cash burn, for now. Over the last year its cash burn actually increased by a very significant 74%. Oftentimes, increased cash burn simply means a company is accelerating its business development, but one should always be mindful that this causes the cash runway to shrink. While the past is always worth studying, it is the future that matters most of all. So you might want to take a peek at how much the company is expected to grow in the next few years.

How Easily Can Imugene Raise Cash?

Given its cash burn trajectory, Imugene shareholders may wish to consider how easily it could raise more cash, despite its solid cash runway. 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 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.

Imugene has a market capitalisation of AU$439m and burnt through AU$73m last year, which is 17% of the company's market value. Given that situation, it's fair to say the company wouldn't have much trouble raising more cash for growth, but shareholders would be somewhat diluted.
