Monday roundup: Ciena, ACE, FLAG, ex2.

Monday roundup: Ciena, ACE, FLAG, ex2. Three upgrade projects, two below the waves and one back on land: Ciena has picked up two subsea upgrade deals. The Africa Coast to Europe (ACE) consortium is deploying Ciena's WL6e tech over top of its existing submarine line terminal equipment. The upgrade will boost capacity above 30Tbps while enhancing visualization and management. ACE spans some 17,000km across 18 landing stations along the west coast of Africa and Europe. Meanwhile, FLAG has selected Ciena's Waveserver platform and WL6e coherent optics for its dedicated fiber pair on the ECHO subsea cable. ECHO's 16,000km of cable connect Singapore and the US via Guam, and complements the rest of FLAG's global footprint. FLAG will be able to offer 400GbE and 800GbE services on the upgraded infrastructure, meeting demand from AI and cloud services. And back on land, eX[2] Technology has polished off a procject up in Michigan. They have completed a 195-mile FTTP network in the city of Holland, a half hour's drive southwest of Grand Rapids near the shores of Lake Michigan. The infrastructure connects up with existing utility-built fiber infrastructure of Holland BPW, boosting access to a broader swath of the city. If you haven't already, please take our Reader Survey!

Ciena targets $14B revenue by 2029 as optical demand outpaces supply

Ciena has set a revenue target of approximately $14 billion by fiscal 2029, driven by sustained demand for optical systems that continues to outpace industry supply. The company also aims for gross margins of about 50% and operating margins of 32% to 35%. Chief financial officer Marc Graff said orders doubled from 2024 to 2025 and are expected to increase by at least 50% in 2026. Ciena anticipates its backlog will reach $10 billion by the end of fiscal 2026. The company expects industry supply and demand to remain imbalanced until 2028. For fiscal 2027, Ciena projects orders to grow by at least 50% and has secured sufficient supply to support at least 30% revenue growth.

Ciena guides to record 25-27% profit margin on price rises of up to 20%

Ciena trades near $334, down from its 52-week high, but still up over 150% year-on-year. The AI networking supplier expects price increases of high single digits to low twenties across product lines, with some increases applying to existing backlog orders. Management projects fiscal 2027 adjusted operating margins of 25% to 27%, calling it record profitability. The company forecasts fiscal 2027 revenue of at least $8.3 billion, representing minimum 30% year-on-year growth. Ciena expects to end fiscal 2026 with over $10 billion in backlog. The price increases come during a component shortage that management doesn't expect to resolve until 2028. About half of Ciena's business now comes from hyperscalers directly. The key risk is whether pricing power holds once supply constraints ease, making adjusted operating margin the critical metric to watch as repriced backlog converts to revenue.

Ciena's backlog surges to $8.5B as AI infrastructure demand outpaces production

Ciena Corporation reported third-quarter fiscal 2026 revenue of $1.67 billion, up 37% year over year, with adjusted earnings per share more than tripling to $2.11. The networking equipment maker's order backlog reached $8.5 billion, growing $800 million in the quarter. The company projects backlog will exceed $10 billion by fiscal year-end, driven by hyperscale customers building AI infrastructure. Optical networking revenue rose 46% to $1.19 billion, whilst cloud provider revenue grew over 80%. Adjusted gross margin hit a record 46.4% and operating margin reached 22.5%. Management guides fiscal 2027 revenue to at least $8.3 billion with operating margin as high as 27%. Ciena signed long-term component agreements through 2029 to secure supply. Two customers accounted for 41.7% of revenue, presenting concentration risk.
