Here's Why We're Watching AVROBIO's (NASDAQ:AVRO) Cash Burn Situation

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 the harsh reality is that very many loss making companies burn through all their cash and go bankrupt.

So should AVROBIO (NASDAQ:AVRO) shareholders be worried about its 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 AVROBIO Run Out Of Money?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. In September 2021, AVROBIO had US$201m in cash, and was debt-free. Importantly, its cash burn was US$104m over the trailing twelve months. So it had a cash runway of approximately 23 months from September 2021. 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 AVROBIO's Cash Burn Changing Over Time?

AVROBIO didn't record any revenue over the last year, indicating that it's an early stage company still developing its business. Nonetheless, we can still examine its cash burn trajectory as part of our assessment of its cash burn situation. With the cash burn rate up 18% in the last year, it seems that the company is ratcheting up investment in the business over time. That's not necessarily a bad thing, but investors should be mindful of the fact that will shorten the cash runway. 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 AVROBIO Raise Cash?

While AVROBIO 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. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. 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.

AVROBIO's cash burn of US$104m is about 45% of its US$232m market capitalisation. That's high expenditure relative to the value of the entire company, so if it does have to issue shares to fund more growth, that could end up really hurting shareholders returns (through significant dilution).

How Risky Is AVROBIO's Cash Burn Situation?

On this analysis of AVROBIO's cash burn, we think its cash runway was reassuring, while its cash burn relative to its market cap has us a bit worried. 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.
