Here's Why Assembly Biosciences (NASDAQ:ASMB) Must Use Its Cash Wisely

There's no doubt that money can be made by owning shares of unprofitable businesses. 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. But while the successes are well known, investors should not ignore the very many unprofitable companies that simply burn through all their cash and collapse.

So should Assembly Biosciences (NASDAQ:ASMB) shareholders be worried about its cash burn? For the purpose of this article, we'll define cash burn as the amount of cash the company is spending each year to fund its growth (also called its negative free cash flow). First, we'll determine its cash runway by comparing its cash burn with its cash reserves.

When Might Assembly Biosciences 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. In June 2023, Assembly Biosciences had US$60m in cash, and was debt-free. Importantly, its cash burn was US$76m over the trailing twelve months. So it had a cash runway of approximately 9 months from June 2023. To be frank, this kind of short runway puts us on edge, as it indicates the company must reduce its cash burn significantly, or else raise cash imminently. The image below shows how its cash balance has been changing over the last few years.

How Is Assembly Biosciences' Cash Burn Changing Over Time?

Assembly Biosciences 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 8.8% over the last year, which suggests that management may be mindful of the risks of their depleting cash reserves. 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 Assembly Biosciences To Raise More Cash For Growth?

While Assembly Biosciences is showing a solid reduction in its cash burn, it's still worth considering how easily it could raise more cash, even just to fuel faster growth. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. Commonly, a business will sell new shares in itself to raise cash and drive 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).

Assembly Biosciences has a market capitalisation of US$50m and burnt through US$76m last year, which is 153% of the company's market value. Given just how high that expenditure is, relative to the company's market value, we think there's an elevated risk of funding distress, and we would be very nervous about holding the stock.

How Risky Is Assembly Biosciences' Cash Burn Situation?

Even though its cash burn relative to its market cap makes us a little nervous, we are compelled to mention that we thought Assembly Biosciences' cash burn reduction was relatively promising. After considering the data discussed in this article, we don't have a lot of confidence that its cash burn rate is prudent, as it seems like it might need more cash soon.
