Optics Stocks Divide: Coherent and Cisco Drop After Earnings While Nokia and Ciena Soar
Coherent (COHR) and Cisco (CSCO) fell after fiscal Q4 results, with COHR down 4.94% and CSCO down 8.48%. Coherent reported $2.05B revenue and $1.74 non-GAAP EPS but disclosed FY2026 operating cash flow of $79.5M vs $1.10B capex. Cisco revenue was $17.25B; margins fell. Ciena (CIEN) and Nokia (NOK) rose on optics demand read-through.
How this was made
The 30-second read
Why it matters
Traders are likely repricing near-term profitability and cash conversion for COHR and CSCO, while extrapolating stronger AI data center interconnect demand for CIEN and NOK.
Market read
This is a same-day earnings-driven supply-chain read-through that differentiates cash flow and margin risk (COHR, CSCO) from demand inflection optimism (CIEN, NOK).
What to watch
Cash flow and margin mix issues at COHR and CSCO could also reappear at optical peers if AI hardware intensity or cost inflation persists, limiting how long the supply-chain rally lasts.
Background
The article frames an optics complex split after fiscal Q4 earnings, with Coherent and Cisco down and Ciena and Nokia up on demand read-through.
Ticker impact
Coherent shares fall 4.94% after results, with operating cash flow down 87.45% versus capex up 150.18%.
Choppy to lower follow-through likely if investors keep focusing on cash burn versus capex intensity.
The article highlights a large YoY operating cash flow decline and much higher capex, which can dominate an otherwise positive revenue/EPS beat.
Cisco drops 8.48% despite revenue growth and AI infrastructure orders, as non-GAAP gross margin falls to 66.3% from 68.4%.
Further volatility possible as traders reprice margin durability and AI infrastructure profitability.
The article explicitly ties the selloff to gross margin decline and heavier AI hardware volume, even with guidance and order strength.
Ciena rises 6.04% on the same earnings read-through, with 39.51% revenue growth and cloud provider revenue at 46%.
Upside bias for CIEN as the market extrapolates stronger DCI/coherent demand into future quarters.
The article links the rally to demand signals and cites CIEN’s cloud growth and the hyperscaler connectivity narrative.
Nokia gains 3.29% as investors buy into pump-laser demand, citing a fourfold increase in pump laser shipments over coming quarters.
Potential continuation if pump-laser demand expectations keep rising across the optical supply chain.
The article uses Lumentum’s conference call quote and Nokia’s AI and cloud order intake to justify the positive read-through.
Market effects
Optics is bifurcating: investors reward vendors tied to DCI/coherent transport demand while penalizing those showing cash flow or margin pressure.
Primarily US-listed names reacting to earnings and supply-chain read-through; ADR mention for Nokia suggests global AI optics demand sensitivity.
AI data center connectivity and modular build constraints are framed as global demand drivers for optical components.
Counterpoint
The positive moves in CIEN and NOK may be overly dependent on read-through from peers’ earnings and a single conference-call narrative rather than their own incremental guidance.
