Ciena and Zscaler become Thursday’s next tests for AI networking and security demand
After Broadcom’s report, investors turn to optical-network capacity and cybersecurity for evidence that AI spending is broadening beyond compute.
In one line: Today’s earnings can show whether the AI capex cycle is pulling networking and security demand higher alongside silicon.
Key facts
- Ciena scheduled fiscal Q3 results before the U.S. market open.
- Zscaler is among companies due to report on September 3.
- Ciena previously raised its fiscal 2026 revenue guidance amid bandwidth demand.
What is scheduled
Ciena is due to release fiscal third-quarter results before the U.S. market open on September 3, followed by its earnings call. Zscaler is also on the day’s earnings calendar. The reports arrive after Broadcom confirmed strong AI semiconductor and networking growth.
Why Ciena matters
Large AI clusters increase data movement inside and between facilities, raising demand for optical networking. Investors will focus on order timing, cloud-customer demand, supply constraints and updated full-year guidance. Strong results would support the view that the infrastructure cycle is broadening beyond accelerators.
Why Zscaler matters
AI adoption expands data flows, identities and application surfaces that enterprises must secure. Security vendors can benefit, but buyers also face tool consolidation and budget scrutiny. Billings, remaining performance obligations and large-customer growth will help separate durable platform demand from AI-themed messaging.
What to watch in both reports
The common question is conversion. For Ciena, do bandwidth orders become revenue at stable margin? For Zscaler, do platform commitments become sustained subscription growth? Guidance and customer commentary will matter more than a one-quarter beat because investors are testing the durability of demand into 2027.
Two different AI read-throughs
Ciena tests the physical movement of data, while Zscaler tests the security layer around users, applications and AI workloads. Strength in both would show that spending is broadening beyond compute. Divergence would help investors identify where budgets are being prioritized as enterprises move from infrastructure purchase to production use.
The downside case
AI language can appear in guidance without producing incremental revenue. For Ciena, the proof is order conversion and margin. For Zscaler, it is billings, retention and large-customer expansion. If management commentary emphasizes opportunity while forward metrics slow, investors should separate narrative exposure from measurable demand.
