Recent news
most recent scored articles · the chip is the article’s score · click to openWall Street Zen lowered its rating on Ciena from "buy" to "hold" in a research note issued on Saturday. The article provides no reason for the downgrade or any price target.
Ciena reported a 37% year-over-year revenue increase in Q3 FY2026, driven by surging AI-related demand. Backlog (orders booked but not yet shipped) reached $8.5 billion in the quarter and is expected to exceed $10 billion by year-end, with management targeting roughly 30% average yearly revenue growth through FY2029.
Space Norway will use Ciena networking technology to upgrade its existing Svalbard subsea cable systems and to equip its new Arctic Way system, which is described as the world's northernmost subsea cable and is expected to begin service in 2028. Space Norway says it will standardize on Ciena's technology across both the new and legacy subsea routes to extend the life of its infrastructure and cut operating costs.
Bank of America is projecting that Ciena could build a $10 billion order backlog and grow revenue 35% to 40% in 2026, saying demand from cloud customers is running ahead of the company's ability to supply components.
Space Norway awarded Ciena a turnkey contract to upgrade its existing Svalbard subsea cable system and deploy networking technology on the new Arctic Way subsea cable. The project extends the life of Space Norway's subsea infrastructure and adds high-resilience connectivity to new Arctic locations.
