Morgan Stanley Downgrades Ciena Amid Margin Concerns and Limited Earnings Growth
Morgan Stanley downgrades Ciena Corp. due to margin pressures and limited near-term earnings potential, highlighting challenges in balancing growth with profitability in the optical networking sector.

Morgan Stanley has downgraded Ciena Corp. (NYSE: CIEN) to Underweight from Equal-weight, citing persistent margin compression and limited near-term earnings upside. The investment bank also reduced its price target on the company to $70 from $73, pointing to Ciena's increasing focus on lower-margin pluggable optical modules as a key factor affecting profitability. Despite higher revenue forecasts for fiscal 2026, earnings per share (EPS) estimates have declined, with gross margins falling short of expectations due to the growth in the pluggables business.
The downgrade reflects concerns over Ciena's strategic shift towards high-speed optical interconnects, including pluggables used in data centers and metro networks. While this move positions Ciena in high-demand areas such as cloud infrastructure and AI workloads, analysts warn it may dilute earnings in the short term. Ciena's shares dipped approximately 1% following the announcement.
In contrast, Morgan Stanley raised price targets for three other networking companies—Corning Inc. (NYSE: GLW), Coherent Corp. (NYSE: COHR), and Lumentum Holdings (NASDAQ: LITE)—signaling optimism about the optical infrastructure sector. However, the firm noted that the datacom segment's lower margins mean revenue growth may not fully translate into EPS upside.
The downgrade underscores the broader challenge Ciena faces in navigating the competitive high-speed connectivity market while maintaining profitability, a dilemma that is expected to persist as the industry evolves.
