CIEN

Ciena's stock experienced volatility in the past six months. In June 2026, despite strong Q2 fiscal 2026 earnings with revenue up 40% to $1.57 billion and adjusted EPS nearly quadrupling to $1.64, the stock declined approximately 17% in 30 days. In September 2026, Q3 fiscal 2026 earnings reported record revenue of $1.67 billion and adjusted EPS of $2.11, with backlog growing to $8.5 billion, yet the stock fell 9.4% due to investor concerns over supply constraints. Later in September 2026, an Investor Forum where Ciena unveiled formal fiscal 2029 targets, including 30% average annual revenue growth, led to several analyst upgrades and a 14% stock surge over five trading days.
