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 LENZ Therapeutics (NASDAQ:LENZ) 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. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

How Long Is LENZ Therapeutics' Cash Runway?

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 September 2024, LENZ Therapeutics had US$217m in cash, and was debt-free. Looking at the last year, the company burnt through US$72m. So it had a cash runway of about 3.0 years from September 2024. Importantly, analysts think that LENZ Therapeutics will reach cashflow breakeven in 4 years. So there's a very good chance it won't need more cash, when you consider the burn rate will be reducing in that period. The image below shows how its cash balance has been changing over the last few years.

How Is LENZ Therapeutics' Cash Burn Changing Over Time?

LENZ Therapeutics 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. During the last twelve months, its cash burn actually ramped up 53%. 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. 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.

Can LENZ Therapeutics Raise More Cash Easily?

Given its cash burn trajectory, LENZ Therapeutics 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. Commonly, a business will sell new shares in itself to raise cash and drive growth. We can compare a company's cash burn to its market capitalisation to get a sense for how many new shares a company would have to issue to fund one year's operations.

LENZ Therapeutics' cash burn of US$72m is about 8.7% of its US$827m market capitalisation. Given that is a rather small percentage, it would probably be really easy for the company to fund another year's growth by issuing some new shares to investors, or even by taking out a loan.

How Risky Is LENZ Therapeutics' Cash Burn Situation?

It may already be apparent to you that we're relatively comfortable with the way LENZ Therapeutics is burning through its cash. For example, we think its cash runway suggests that the company is on a good path. Although its increasing cash burn does give us reason for pause, the other metrics we discussed in this article form a positive picture overall. Shareholders can take heart from the fact that analysts are forecasting it will reach breakeven. Looking at all the measures in this article, together, we're not worried about its rate of cash burn; the company seems well on top of its medium-term spending needs. Separately, we looked at different risks affecting the company and spotted 3 warning signs for LENZ Therapeutics (of which 1 shouldn't be ignored!) you should know about.
