Two Positive Attributes:
1. Long-Term Revenue Growth Shows Strong Momentum
A company’s long-term performance is an indicator of its overall quality. Any business can have short-term success, but a top-tier one grows for years. Thankfully, OSI Systems’s 7.1% annualized revenue growth over the last five years was solid. Its growth beat the average business services company and shows its offerings resonate with customers. 
2. Outstanding Long-Term EPS Growth
Analyzing the long-term change in earnings per share (EPS) shows whether a company's incremental sales were profitable – for example, revenue could be inflated through excessive spending on advertising and promotions.
OSI Systems’s EPS grew at a remarkable 12.6% compounded annual growth rate over the last five years, higher than its 7.1% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.
One Reason to be Careful:
Free Cash Flow Margin Dropping
If you’ve followed StockStory for a while, you know we emphasize free cash flow. Why, you ask? We believe that in the end, cash is king, and you can’t use accounting profits to pay the bills.
As you can see below, OSI Systems’s margin dropped by 10.1 percentage points over the last five years. It may have ticked higher more recently, but shareholders are likely hoping for its margin to at least revert to its historical level. If the longer-term trend returns, it could signal it’s in the middle of a big investment cycle. OSI Systems’s free cash flow margin for the trailing 12 months was 2.5%.
Final Judgment
OSI Systems’s merits more than compensate for its flaws, and with its shares topping the market in recent months, the stock trades at 21.2× forward P/E (or $212.01 per share). Is now the time to initiate a position? See for yourself in our full research report, it’s free.
