There's no doubt that money can be made by owning shares of unprofitable businesses. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.

Given this risk, we thought we'd take a look at whether OmniAb (NASDAQ:OABI) shareholders should be worried about its cash burn. In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

How Long Is OmniAb's Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. As at March 2026, OmniAb had cash of US$49m and no debt. In the last year, its cash burn was US$26m. Therefore, from March 2026 it had roughly 23 months of cash runway. Importantly, analysts think that OmniAb will reach cashflow breakeven in 3 years. Essentially, that means the company will either reduce its cash burn, or else require more cash. You can see how its cash balance has changed over time in the image below.

How Well Is OmniAb Growing?

We reckon the fact that OmniAb managed to shrink its cash burn by 34% over the last year is rather encouraging. Revenue also improved during the period, increasing by 5.5%. Considering the factors above, the company doesn’t fare badly when it comes to assessing how it is changing over time. 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 OmniAb Raise Cash?

While OmniAb seems to be in a fairly good position, 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. 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.

OmniAb's cash burn of US$26m is about 7.1% of its US$365m 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 OmniAb's Cash Burn Situation?

OmniAb appears to be in pretty good health when it comes to its cash burn situation. One the one hand we have its solid cash runway, while on the other it can also boast very strong cash burn relative to its market cap. Shareholders can take heart from the fact that analysts are forecasting it will reach breakeven. Based on the factors mentioned in this article, we think its cash burn situation warrants some attention from shareholders, but we don't think they should be worried.
