So what 

The energy-drink maker easily beat estimates on both top and bottom lines. Sales increased 16.8% to $753.8 million, ahead of expectations at $723.9 million, and growth was particularly strong outside the U.S. -- international sales were up a third to $193.5 million.

On the bottom line, adjusted earnings per share increased from $0.22 a year ago to $0.35, beating the consensus at $0.30. CEO Rodney Sacks said he was pleased with "continued progress on the strategic alignment of our distribution system with Coca-Cola bottlers." The energy-drink maker has grown by partnering with Coke bottlers to use their expansive distribution networks.

Now what

Management did not issue guidance, but the growing relationship with Coke distributors seems to bode well for the current year. Energy drinks is one of the few segments of the soft-drink market that has seen strong growth in recent years, and one reason why Coca-Cola took a stake in Monster in 2015. However, the stock has traded mostly sideways for the last couple years as the valuation may have gotten ahead of itself.

At a P/E of 40, the price may still be rich, but there should be continued long-term growth, with Coke's distribution pipeline helping it out.
