Detailed narrative
AI-led demand up-cycle across cloud and service providers
Ciena grew revenue 40% YoY to $1.57B, framing an AI-driven demand cycle spanning the WAN and in-and-around the data center. Largest hyperscalers have raised 2026 capex with indications of continued expansion into 2027 and beyond, and management expects an increasingly larger proportion of that spend to shift to network infrastructure as constrained compute is monetized.
Service providers are reinvesting after several years of underinvestment (preoccupied with 5G), creating net-new long-haul, metro and MOFN opportunities. Management's latest view is that its addressable market roughly doubles to ~$50B by 2029.
RLS hyper-rail: first multi-rail hyperscaler order
Ciena announced the industry's first multi-rail order from a leading hyperscaler for its next-generation RLS hyper-rail intelligent line system, co-created with multiple hyperscalers on an innovative photonic design supporting multiple fiber pairs in parallel over hundreds of kilometers with advanced amplification.
It targets high-intensity training over greater distances, scale-across architectures, DCI and inferencing, delivering higher density with materially improved space and power efficiency at amplifier sites. Deals are each sized at hundreds of millions over multiple years, revenue begins in 2027 and is expected to ramp linearly, and management is ahead of its adoption expectations while engaged with most major hyperscalers, neoscalers and service providers.
DCOM drives 88% routing & switching growth
The data center out-of-band management (DCOM) solution — combining routing/switching with Ciena's PON technology — is ramping strongly and was the primary driver of 88% YoY routing & switching growth, though the segment grew well even excluding DCOM. Beyond anchor customer Meta, Ciena received initial orders from a second hyperscaler and is progressing lab qualifications with a third.
Management characterized DCOM as a durable, multi-year, multi-faceted application ('not one and done') with a total TAM it sizes at $1-3B by 2029, and a key part of its inside-the-data-center strategy.
Interconnect portfolio: coherent modules, pluggables and Nubis
AI demand is extending across the interconnect portfolio. Ciena secured a new coherent-module win with a major hyperscaler for scale-across metro and long-haul DCI — a competitive takeaway co-developed with the customer. It sees strong hyperscaler demand for 400G and 800G pluggables and remains on track to more than double pluggable revenue from 2025, plus a first win with a major switch OEM for WaveLogic 5 and 6 nano plugs.
On Nubis, its Nitro linear redriver received final chip back, is performing well and is on track for general availability this summer, while the Vesta 200 6.4T optical engine for CPO is seeing increased industry momentum for open ecosystems.
Service providers and MOFN reacceleration
Service-provider revenue grew 28% YoY, driven by two dynamics: a refresh of optical infrastructure underinvested for roughly five years during the 5G build, and managed optical fiber networks (MOFN) built for hyperscalers and cloud players across countries. India service-provider revenue more than doubled YoY on strong MOFN demand.
Management views this as multi-year and durable given hyperscalers' difficulty covering last-mile and regulatory footprints globally. Notably, a previously >10% service-provider customer fell below the 10% threshold purely because hyperscalers are growing so much faster.
Supply constraints, gross margin and 'value exchange'
Adjusted gross margin reached 44.9% (up 4 points YoY, 90 bps above guide) on engineering cost reductions, mix and price optimization — the third consecutive quarterly gross-margin raise. Management stressed an ongoing supply-demand imbalance, with constraints on coherent driver modems (buffered by Ciena's vertical integration) and pump lasers for amplifiers.
It is investing with suppliers to secure capacity while pursuing 'value exchange' with customers spanning pricing, supply-risk sharing and working-capital terms. Hyper-rail and DCOM ramps, interconnect/components growth and value exchange underpin a path to further margin expansion.
Backlog quality and the COVID contrast
Backlog rose more than $600M sequentially to a record $7.7B (roughly $6.4B hardware), with ~80% of hardware expected to convert to revenue within the next 12 months and visibility management calls well beyond historical norms into 2027. Management explicitly contrasted this with the post-COVID hangover: product is going into the ground rather than warehouses, thanks to service engagements and co-collaboration, and it sees no inventory buildup, no push-out requests and no cancellations — in fact customers would take even more product in 2026 if Ciena could deliver it.
Capital returns, cash flow and financial model
Free cash flow was $219M (13.9% of revenue) and cash ended at $1.4B, aided by a 20-day improvement in the cash conversion cycle on faster inventory turns and better payables execution. Ciena returned $83M via buyback at an average $371/share and remains on track to spend $250-275M of capex.
Adjusted EPS of $1.64 was nearly 4x the year-ago level. Management raised FY26 revenue to $6.3B (+32%) and reiterated confidence in operating leverage and meaningful EPS acceleration into 2027 and beyond. The call also marked CEO Gary Smith's 100th earnings call and 25th year as CEO.
