The past five years for Marinus Pharmaceuticals (NASDAQ:MRNS) investors has not been profitable

In this article:

It is a pleasure to report that the Marinus Pharmaceuticals, Inc. (NASDAQ:MRNS) is up 53% in the last quarter. But will that heal all the wounds inflicted over 5 years of declines? Unlikely. Indeed, the share price is down a whopping 72% in that time. The recent bounce might mean the long decline is over, but we are not confident. The important question is if the business itself justifies a higher share price in the long term.

Now let's have a look at the company's fundamentals, and see if the long term shareholder return has matched the performance of the underlying business.

Marinus Pharmaceuticals wasn't profitable in the last twelve months, it is unlikely we'll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. When a company doesn't make profits, we'd generally expect to see good revenue growth. That's because it's hard to be confident a company will be sustainable if revenue growth is negligible, and it never makes a profit.

In the last half decade, Marinus Pharmaceuticals saw its revenue increase by 85% per year. That's well above most other pre-profit companies. So it's not at all clear to us why the share price sunk 11% throughout that time. It could be that the stock was over-hyped before. We'd recommend carefully checking for indications of future growth - and balance sheet threats - before considering a purchase.

A Different Perspective

While the broader market lost about 8.6% in the twelve months, Marinus Pharmaceuticals shareholders did even worse, losing 42%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 11% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
