    Executive summary

    Ciena Q2 FY26 — Record revenue up 40% on AI-led demand; first multi-rail hyperscaler order

    AI-led demand from both hyperscalers and long-underinvested service providers is pushing Ciena into a multi-year up-cycle, with co-created wins in next-gen line systems, DCI and interconnect positioning it to take share as its addressable market expands. The binding constraint is now supply, not demand — management is investing to secure capacity while using pricing and 'value exchange' to lift margins into 2027.

    Highlights

    5
    • Record revenue of $1.57B, up 40% YoY and $71M above guidance, led by optical networking +42% and routing & switching +88%

    • Adjusted gross margin of 44.9% (up 4 full points YoY, 90 bps above guide) and adjusted EPS of $1.64, nearly 4x the year-ago figure

    • Backlog rose more than $600M sequentially to a record $7.7B, with visibility into 2027; FY26 revenue guide raised to $6.3B (32% growth)

    • First-ever multi-rail order won from a leading hyperscaler for the RLS hyper-rail platform, with each such deal sized at hundreds of millions over multiple years

    • Free cash flow of $219M (13.9% of revenue), $1.4B cash, and cash conversion cycle improved 20 days QoQ

    Concerns

    4
    • Supply is not keeping pace with demand — constrained components include pump lasers for amplifiers and coherent driver modems (CDMs)

    • Customer concentration: two cloud providers were each >10% of revenue and together ~1/3 of Q2 revenue

    • Adjusted OpEx rose to $398M on higher variable compensation; FY26 OpEx guide raised to ~$1.61B

    • FY26 gross-margin guide of 44.5%-45% implies possible H2 caution given mix and inflationary input pressures; hyper-rail contributes $0 revenue until later this year

    Risks & headwinds

    6
    Supply not keeping pace with demandongoing, at least the next few years

    Constrained components include coherent driver modems (CDMs) and pump lasers for amplifiers; supply-security investments are ~10% of the raised FY26 OpEx and part of $250-275M capex

    Mitigation: Most vertically integrated supplier buffers modem supply; daily supply-chain work, additional supplier commitments/capacity investment, and engineering cost reductions

    Customer concentrationcurrent

    Two cloud providers each >10% of revenue, together ~1/3 of Q2 revenue

    Mitigation: Diversification into service providers (+28%), neoscalers and MOFN; broad multi-use-case portfolio

    Inflationary input cost pressure on gross marginH2 FY26 and beyond

    Not quantified; cited as risk to implied H2/Q4 gross margin within the 44.5%-45% FY guide

    Mitigation: Engineering cost reductions, 'value exchange' (pricing, supply-risk sharing, working-capital terms) with customers and suppliers

    Backlog conversion / double-booking (post-COVID lesson)through 2026-2027 delivery window

    Backlog $7.7B; management reports none of the COVID-era warning signs

    Mitigation: Co-creation and service engagements confirm product going into the ground not warehouses; no inventory buildup, push-outs or cancellations observed

    Hyper-rail ramp/execution risk2027 onward

    $0 hyper-rail revenue until introduction later in FY26; meaningful uptick not until 2027

    Mitigation: First order already won, co-created with hyperscalers; ahead of adoption expectations; multiple engagements in progress

    Competitive encroachment from component vendors into systemsongoing

    Unquantified

    Mitigation: Deep moat — end-to-end system integration across thousands of km, control software, back-office integration and 24/7 global services; continued system-vendor consolidation favors scaled players

    Q&A highlights

    9

    How large is the first multi-rail hyperscaler win, how is it tracking vs expectations, and are other engagements similar?

    Gary called it a strategic standardization decision by the hyperscaler enabling high-intensity training over greater distances. Deals vary but are each hundreds of millions over multiple years, begin rolling out through 2027, and Ciena is engaged with most major hyperscalers and is a little ahead of its adoption expectations.

    given the nature of them, they are all hundreds of millions over multiple years... we're a little ahead of where we thought we'd be from an adoption point of view

    Detailed Narrative

    01

    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.

    02

    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.

    03

    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.

    04

    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.

    05

    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.

    06

    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.

    07

    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.

    08

    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.
