Citi's managing director Atif Malik cited Ciena's leadership in optical transport gear and new demand from AI data centers as key drivers. Ciena reported record fiscal Q3 revenue of $1.67 billion (up 37%) and adjusted earnings of $2.11 per share (up 215%), also raising its full-year revenue guidance to $6.42 billion. The bank views the post-earnings sell-off as a buying opportunity.
