What happened

The company also repurchased 1.4 million shares during the quarter for $61.2 million, an average price of around $43.71 per share. For perspective, the stock currently trades around $49.60 per share as of this writing.

Ciena CEO Gary Smith called it an "excellent" quarter "with strength across all regions," adding: "We are encouraged by increased customer activity that, when combined with our elevated backlog, market leadership, and expanding addressable market, we believe will drive growth and market share gains going forward."

Now what

During the subsequent conference call with analysts, Ciena management increased their full fiscal-year outlook to call for revenue growth of 20% to 22% (up from 16% to 18%). It also reiterated previous guidance for full-year gross margin ranging from 42% to 44%.
