What management had to say 
Ruckus Wireless CEO Selina Lo stated:

Our fourth-quarter revenue was affected by a multimillion-dollar E-rate opportunity that was postponed late in the quarter. Nevertheless, we achieved non-GAAP operating margin at the high end of guidance, demonstrating strong operating execution. I believe our strategy remains sound and our product portfolio differentiated, keeping Ruckus in a position to outgrow the market again in 2016. We are equally focused on driving bottom-line growth in 2016, and we are committed to grow earnings faster than revenue, driving operating margin expansion throughout the year.

Looking forward 
For the current quarter, Ruckus Wireless expects revenue in the range of $96 million to $101 million, operating margin of 8.5% to 11%, and adjusted earnings per diluted share of $0.08 to $0.10. By contrast, analysts anticipated earnings right at the midpoint of Ruckus' guidance range, and revenue of $99.3 million. 

However, investors are rightly encouraged that Ruckus was able to achieve these solid results despite the postponed multimillion-dollar E-rate opportunity mentioned by Lo. What's more, it's good to see cash from operations rebound this quarter, especially after watching the metric plummet 48% year over year along with mediocre growth in Q3. Considering Ruckus is also aiming for earnings to outgrow revenue as operating margins expand in the coming year -- and with shares still down nearly 25% year to date -- it's no surprise investors are bidding up Ruckus Wireless stock today.
