Summary and Conclusions
- Corning is entering Q3 2026 with strong momentum: Q2 2026 delivered +17% core sales growth and +30% core EPS growth, led by Optical Communications (sales +32% YoY, Enterprise Networks +65% YoY) and Solar (+90% YoY).
- Q3 2026 guidance is robust: Management expects core sales of $4.9B–$5.0B (+16% YoY) and core EPS of $0.85–$0.89 (+28% YoY), both above Q3 2025 actuals and in line with consensus.
- Key drivers to watch:
- Optical Communications: Orders are accelerating, driven by Gen AI product adoption and major long-term agreements (Meta, Amazon, NVIDIA, Verizon). Margins are expanding (Q2 2026 Optical net income margin: 21%).
- Solar: After a maintenance shutdown in Q2, management expects improved profitability in Q3 as the ramp continues. The segment is targeting >$3B revenue with above-corporate-average margins by end-2027.
- Photonics MAP: No material revenue yet, but management continues to signal a $10B opportunity by 2030; timing of scale-up adoption is a key swing factor.
- Capacity Expansion: Corning is executing on a 50% increase in fiber production and 10x increase in connectivity capacity, underpinned by customer prepayments and risk-sharing agreements.
- Comparables: Q3 2025 was a strong base (+14% core sales, +24% core EPS), so Q3 2026 faces a tough YoY comp but is expected to deliver even stronger growth.
