Key Takeaways:
- Ciena reported record Q2 revenue of $1.17 billion, beating consensus estimates
- Earnings surged 290% year over year on AI-led optical networking demand
- Company raised fiscal 2026 revenue growth guidance to 18%-22%
Key Takeaways:

Ciena Corp. reported record fiscal second-quarter revenue and a 290% surge in earnings, driven by AI-led demand for optical networking equipment.
"The results reflect accelerating adoption of our optical networking solutions as cloud providers and enterprises scale AI infrastructure," Gary Smith, chief executive officer at Ciena, said.
Revenue for the quarter ended April 30 reached $1.17 billion, up 28% from a year earlier and above the $1.09 billion consensus estimate compiled by FactSet. Adjusted earnings per share came in at $1.42, compared with $0.36 a year ago and topping the $0.98 analyst forecast. The company's networking segment posted a 34% revenue increase as data-center operators upgraded fiber-optic links to handle AI workloads.
The strong performance pushed Ciena to raise its full-year fiscal 2026 outlook. The company now expects annual revenue growth of 18% to 22%, up from a prior range of 14% to 17%. Adjusted operating margin is projected at approximately 18%, compared with the earlier forecast of 15%. The guidance raise suggests management expects AI-related network buildouts to continue accelerating through the second half of the year.
Ciena's results follow a pattern across the networking sector. Hewlett Packard Enterprise last week reported a 148% surge in networking revenue, while Broadcom posted record AI semiconductor revenue of $10.8 billion, with networking accounting for nearly 40% of that total. The convergence of AI cluster expansion and optical transport upgrades is creating a multiyear demand cycle for companies supplying the physical layer of data-center connectivity.
The company did not disclose specific segment-level gross margins or provide a quarterly guidance range for the current period. Ciena shares rose 8.2% in after-hours trading following the release.
The guidance raise signals that Ciena's management expects AI-driven optical networking demand to sustain through fiscal 2027. Investors will watch the company's Q3 earnings call for updates on order backlog and gross margin trajectory as component supply constraints ease.
