Ciena Corporation (CIEN) Earnings

Management highlights

- Market & TAM Outlook * AI-driven demand from hyperscaler/neoscaler cloud customers and reinvestment from service providers (after five years of underinvestment in optical infrastructure focused on 5G) is creating durable, robust growth for high-speed, low-latency connectivity. * Ciena estimates its total addressable market (TAM) will double to approximately $50 billion by 2029, with most growth coming from in-and-around data center connectivity; the in/around data center market is projected to reach $8-$10 billion by 2029, while the traditional long-haul/metro WAN optical transport market will exceed $20 billion by 2029. - Product & Commercial Milestones * Announced the industry's first multi-rail order for the new RLS HyperRail next-generation intelligent line system, co-created with a leading hyperscaler. The platform delivers higher density, better space/power efficiency for long-distance data center interconnect and AI training workloads, with rollout starting in 2027; engagements with multiple other hyperscalers and service providers are progressing ahead of adoption expectations, and each deal will total hundreds of millions of dollars over multiple years. * DCOM (out-of-band management solution combining routing/switching and PON technology) is ramping rapidly, with initial orders received from a second hyperscaler and lab qualifications ongoing with a third. DCOM is expected to become a $1-$3 billion annual business by 2029, representing a durable multi-year growth opportunity. * Secured a new competitive takeaway win for high-performance coherent modules with a major hyperscaler, and won a first design win for WaveLogic 5/6 nano plugs with a major switch OEM, extending Ciena's go-to-market reach for its interconnect technology. * Nitro (Nubis' linear redriver for active copper cables) has passed final chip validation and is on track for general availability in summer 2026. Demand for Vesta 206.4T (CPO optical engine) has increased alongside growing industry demand for open CPO ecosystems, validating the strategic value of the Nubis acquisition. * Neoscaler demand is growing, with significant wins across most major players, and incremental services opportunities as neoscalers look to deploy networks quickly without expanding internal staff. - Operational & Financial Performance * Achieved an adjusted gross margin of 44.9%, up 400 basis points year-on-year, driven by engineering cost reductions, favorable product mix, and price optimization. Adjusted operating margin reached 19.5%, and adjusted EPS hit $1.64, nearly quadrupling the year-ago figure. * Backlog grew sequentially by over $600 million to $7.7 billion, with 80% of the backlog expected to be delivered within the next 12 months. Improved the cash conversion cycle by 20 days quarter-over-quarter, driving free cash flow of $219 million (13.9% of revenue) and a cash balance of $1.4 billion. * CapEx remains on track to total $250-$275 million for fiscal 2026, with investments focused on securing supply chain capacity for future demand, while $83 million was returned to shareholders via stock buybacks in Q2.

Guidance

- Q3 2026 guidance calls for revenue of approximately $1.625 billion (±$50 million), adjusted gross margin of 45% (±50 basis points), adjusted operating expenses of ~$410 million (±$10 million), and an adjusted operating margin of 19% to 20%. - Full fiscal 2026 guidance was upwardly revised from prior levels: total revenue is now projected at $6.3 billion (±$100 million), with midpoint year-on-year revenue growth of 32%. The adjusted gross margin guidance range is 44.5% to 45%, and adjusted operating expenses are projected at ~$1.61 billion (±$20 million), with an adjusted operating margin of 19% (±50 basis points). - Management expects backlog to increase further through the end of 2026, provides strong visibility into 2027 performance, and projects continued operating leverage and EPS acceleration into 2027 and beyond.

Segment performance

Ciena's total Q2 2026 revenue reached $1.57 billion, growing 40% year-on-year. Optical networking (the largest segment) grew 42% year-on-year, driven by 55%+ annual growth for the RLS and Wave Server product lines, contributing ~60-65% of total revenue based on segment growth trends. Routing and switching grew 88% year-on-year, with the fast-ramping DCOM (data center out-of-band management) solution driving the majority of this growth, even as the core routing and switching business delivered solid standalone growth; this segment contributes approximately 15-20% of total revenue. Interconnects (including WaveLogic modems, pluggables, co-packaged optics, and components) is growing rapidly, with 2026 pluggable revenue on track to more than double 2025 levels, contributing approximately 10-15% of total revenue. By customer type, direct cloud customer revenue grew 70% year-on-year, while service provider revenue grew 28% year-on-year, with NDS service provider revenue more than doubling annually driven by strong demand for managed optical fiber network (MOFN) deployments. Two large cloud customers each contributed more than 10% of Q2 revenue, together accounting for ~33% of total quarterly revenue.

Risks & headwinds

- Ongoing global supply-demand imbalance leaves supply constrained relative to robust customer demand, with particular tightness for modem components (CDMs) and pump lasers for optical amplifiers. While Ciena's vertical integration and proactive capacity investments with suppliers help mitigate these constraints, they remain a core operational risk. - Inflationary input costs create pressure on margins, though management has mitigated this so far through engineering cost reductions and value exchanges with customers. - Forward-looking statements are inherently subject to risks and uncertainties that could cause actual results to differ materially from current projections, as detailed in Ciena's 10-K and upcoming 10-Q filings.

Analyst Q&A

• Q: What is the expected deployment timeline and revenue materiality of the first RLS HyperRail multi-rail hyperscaler win? /

  A: The win is a strategic standardization agreement that will begin rolling out in 2027. Each multi-year HyperRail deal is expected to total hundreds of millions of dollars, and adoption across hyperscalers is progressing ahead of Ciena's initial expectations. HyperRail is also seeing strong traction with large service providers focused on the wholesale MOFN market, so it will deliver linear growth starting in 2027 across multiple customer segments. Meaningful HyperRail revenue will start in 2027.

• Q: What portion of the increased 2026 operating expense guidance comes from variable compensation versus supply chain investments, and what is the long-term OpEx trajectory? /

  A: Approximately 90% of the OpEx increase is variable compensation tied to higher-than-expected order and revenue performance, while 10% is for incremental supply chain security investments. Management reaffirmed that Ciena's business model will continue to generate operating leverage, with revenue growing faster than OpEx over the long term, leading to continued EPS strengthening.

• Q: How does the current backlog differ from the post-COVID backlog dynamic that led to delivery delays and cancellations? /

  A: Unlike the post-COVID period, when customers were building inventory in warehouses, today's backlog represents immediate deployment need: customers would take delivery faster if Ciena could supply more product, and there are no requests for delivery delays or cancellations. 80% of the current $7.7 billion backlog is expected to be delivered within the next 12 months, giving management high confidence in near-term revenue conversion.

• Q: What is the gross margin profile for RLS HyperRail, and how will it impact company-wide margins? /

  A: HyperRail delivers a step function increase in margin accretion compared to existing single-rail RLS products, which have already seen meaningful margin improvements over the past several years. As HyperRail becomes a larger component of Ciena's revenue mix, it will drive company-wide gross margin expansion starting in 2027, which aligns with Ciena's long-term gross margin roadmap.
