Q: Amit Daryanani asked about how cloud market vs North America telco vs international stack up in the 8%-11% growth assumption.

A: Gary Smith said service provider market in North America is coming into balance, with cloud and AI growth on top, and steady improvement in Europe and international markets like India.

Q: Amit Daryanani also asked about obsolescence risk in Q1 and gross margin improvement.

A: Jim Moylan said the obsolescence charge in Q4 was influenced by non-repeatable factors, not expecting recurrence, and gross margin improvement is due to mix shift towards line systems.

Q: Simon Leopold asked about customer concentration in fiscal 2025.

A: Jim Moylan said 10% customers move around, but combination of makeup is not likely to change much.

Q: George Notter asked about gross margin guide and headcount.

A: Jim Moylan said 2025 will have heaviest mix of line systems, and headcount dropped due to terminations and not adding headcount, with OpEx up due to incentive plans and merit increases.

Q: Meta Marshall asked about customers' ability to deploy equipment and OpEx investments.

A: Gary Smith said Ciena is helping with deployments and confident in capability, and OpEx investments are for operating leverage.

Q: David Vogt asked about short-reach coherent opportunities and gross margin expansion.

A: Scott McFeely said short-reach coherent opportunities include metro DCI and campus, with revenue flow in 2026, and Jim Moylan said gross margin will expand to support 15%-16% operating margin.

Q: Adrian Colby asked about supply chain optimization and tariff exposure.

A: Scott McFeely said working on supply chain optimization, and Jim Moylan said tariffs from new administration are speculative with no impact factored in.

Q: Ruben Roy asked about components and competitive environment in DCI.

A: Scott McFeely said Ciena is willing to transact as customers see fit, with growth in metro DCI and winning early bids for 800-gig plug.

Q: Samik Chatterjee asked about interplay between orders, backlog, and TAM.

A: Jim Moylan said order intake is strong but backlog uncertain, and Gary Smith said less seasonality due to cloud exposure.

Q: Tal Liani asked about pluggable margins and carrier deployments.

A: Jim Moylan said pluggable margins will improve as volumes ramp, and Gary Smith said carrier deployments are recovering and driven by cloud-related opportunities like Mofen.
