Is PepGen (NASDAQ:PEPG) In A Good Position To Deliver On Growth Plans?

Just because a business does not make any money, does not mean that the stock will go down. For example, although software-as-a-service business Salesforce.com lost money for years while it grew recurring revenue, if you held shares since 2005, you'd have done very well indeed. 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 PepGen (NASDAQ:PEPG) shareholders be worried about its cash burn? In this article, we define cash burn as its annual (negative) free cash flow, which is the amount of money a company spends each year to fund its growth. Let's start with an examination of the business' cash, relative to its cash burn.

Does PepGen Have A Long Cash Runway?

Importantly, its cash burn was US$86m over the trailing twelve months. So it had a cash runway of approximately 23 months from September 2025. 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.

How Is PepGen's Cash Burn Changing Over Time?

PepGen 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. Over the last year its cash burn actually increased by 3.6%, which suggests that management are increasing investment in future growth, but not too quickly. That's not necessarily a bad thing, but investors should be mindful of the fact that will shorten the cash runway. Clearly, however, the crucial factor is whether the company will grow its business going forward. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.

How Easily Can PepGen Raise Cash?

Since its cash burn is increasing (albeit only slightly), PepGen shareholders should still be mindful of the possibility it will require more cash in the future. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. One of the main advantages held by publicly listed companies is that they can sell shares to investors to raise cash and fund 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.

PepGen's cash burn of US$86m is about 23% of its US$368m market capitalisation. That's not insignificant, and if the company had to sell enough shares to fund another year's growth at the current share price, you'd likely witness fairly costly dilution.
