Despite currently being unprofitable, Glaukos (NYSE:GKOS) has delivered a 79% return to shareholders over 5 years

Glaukos Corporation (NYSE:GKOS) shareholders have seen the share price descend 16% over the month. On the bright side the returns have been quite good over the last half decade. It has returned a market beating 79% in that time.

In light of the stock dropping 3.6% in the past week, we want to investigate the longer term story, and see if fundamentals have been the driver of the company's positive five-year return.

Glaukos isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. When a company doesn't make profits, we'd generally expect to see good revenue growth. Some companies are willing to postpone profitability to grow revenue faster, but in that case one does expect good top-line growth.

For the last half decade, Glaukos can boast revenue growth at a rate of 14% per year. That's a fairly respectable growth rate. Revenue has been growing at a reasonable clip, so it's debatable whether the share price growth of 12% full reflects the underlying business growth. The key question is whether revenue growth will slow down, and if so, how quickly. Lack of earnings means you have to project further into the future justify the valuation on the basis of future free cash flow.

A Different Perspective

We're pleased to report that Glaukos shareholders have received a total shareholder return of 3.6% over one year. However, that falls short of the 12% TSR per annum it has made for shareholders, each year, over five years. Potential buyers might understandably feel they've missed the opportunity, but it's always possible business is still firing on all cylinders. 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.
