Prepared Metrics

Q&A Batch (1-5 of 7)

Q1 — Ruben Roy

• Topic: Data center momentum drivers by production field and customer visibility
• Key points:
  • Lab side driven by optical transport and PCIe test products for AI chips (training/inference); same equipment bought by NAMs building optical switches.
  • Production side sees momentum in co-packaged optics, leveraging legacy JDS Uniphase products for spectral/optical performance; also selling to semiconductor vendors for integrated packaged optics.
  • Field instrumentation: fiber monitoring demand from data centers is higher than from regular service providers; data center now drives ~40%–45% of field instruments, approaching maybe 50%.
  • 800G remains a high-volume driver; 1.6T was released 1.5 years ago, now ramping in lab with early production products to module vendors.
• Mgmt stance: Bullish — portfolio perfectly aligned with AI/optical gear demand across lab, production, and field.

Q2 — Mehdi Hosseini

• Topic: Longer-term earning power and revenue scaling potential
• Key points:
  • NSE business nearing 20% operating profit; every incremental dollar in NSE yields ~$0.45 drop-through to bottom line.
  • OSP gross margin moving from mid-60s–70s to high 80s–low 90s, adding couple of percentage points to operating margin.
  • Blended operating margin currently ~23%–24%; as NSE strengthens, could move into mid-20s or higher.
  • Effective tax rate this quarter ~12% due to U.S. NOLs; incremental profit in U.S. comes at virtually 0% tax.
  • $500 million quarterly revenue target called “entirely realistic”; current June quarter midpoint ~$232M.
• Mgmt stance: Bullish — strong operating leverage (40%–45% incremental margin), tax benefits, and broadening test requirements (co-packaged optics, fiber manufacturing) support growth.

Q3 — Ryan Koontz

• Topic: Data center customer mix and Spirent synergies; defense/wireless opportunities
• Key points:
  • Largest data center customer bucket: hyperscalers (buy for data centers + run own R&D); next: module/system makers; then silicon vendors; distribution fairly balanced.
  • Spirent integration: upgrading hardware performance of their products; first integrated product will be 3.2T; leveraging 800G position with their 800G Ethernet test.
  • PNT (positioning, navigation, timing): most current revenue from pre-acquisition designs; funnel of wins over last 12 months will drive momentum; now winning U.S. Tier 1 defense players after implementing ITAR/secure access.
  • Wireless: focused on 5G+/6G, AI RAN, and ground-to-satellite communication.
• Mgmt stance: Bullish — cross-selling with Spirent beginning; defense moving into bigger leagues; wireless focused on next-gen applications.

Q4 — Andrew Spinola

• Topic: Component shortages, supply constraints, and restructuring impact on margins
• Key points:
  • No long-term supply agreements due to low volumes; focus on early access to alpha/beta silicon for test products.
  • Supply shortages exist (especially memory, deficit expected till 2030), but Viavi’s volume requirements are manageable; inventory increased single-digit millions in March to secure components.
  • Restructuring: ~$30 million announced; ~1/3 will be reinvested; most implemented by end of fiscal year (June quarter), remainder through end of calendar year.
  • Incremental margins currently 40%–45%; could go higher in second half of fiscal 2027 (first half calendar 2027) as restructuring materializes and seasonality (September down quarter) passes.
• Mgmt stance: Neutral-to-bullish — supply chain managed via inventory bets and early access; restructuring to improve fall-through over time.

Q5 — Michael Genovese

• Topic: Testing bottlenecks with silicon photonics and co-packaged optics
• Key points:
  • Bottlenecks moving to packaging and test/measurement for electronics, optics, engines, and ASICs as co-packaged optics proliferate.
  • (No additional specific numbers or guidance provided in the exchange.)
• Mgmt stance: (No explicit stance given; analyst comment only, no management response in provided text.)

Q&A Batch (6-7 of 7)

Q6 — Michael Genovese

• Topic: 测试封装业务战略地位及CPO/OCS收入展望
• Key points:
  • 测试封装从后端附属品转变为系统级战略资产，涉及玻璃基板、光子集成电路与电子集成电路的异构集成，以及共封装光学（CPO）置于芯片外围。
  • 公司技术被拉入从光学元件到晶圆级封装、异构集成封装直至大型测试平台的完整价值链，这是3个季度前未考虑的新业务。
  • 当前数字中已包含早期销售，但“可预见的未来”指2-3个季度后开始爬坡，目前仍处于早期阶段。
• Mgmt stance: 乐观（管理层认为测试封装领域获得空前重视，公司技术和产品被注入新生命力，且OCS测试市场份额可能很高）

Q7 — Timothy Savageaux

• Topic: Spirent季度收入指引、NSE有机增长率及业务板块拆分
• Key points:
  • Spirent本季度收入占比54.2%，受益于上季度推迟的订单；预计日历年度年化运行率约2亿美元，季度拆分约45%/55%，下季度（6月）收入约4800万美元。
  • 有机NSE业务当前季度（Q4）增长率接近40%，全年超30%；但管理层指出维持相同百分比增速困难，因基数扩大，但绝对美元增长可维持。
  • 数据中心收入退出速度接近NSE的40%+，服务提供商接近35%，航空航天与国防略超15%；预计不久数据中心将达NSE的50%。
• Mgmt stance: 乐观（管理层认为若客户按计划支出，增长仍有很大空间，且仍处于爬坡早期阶段；无人机业务收购方已超额完成所有预测，为Viavi唯一首年超预期的收购）
