Near-term (0-6mo)

Earnings 4/28 — Optical Communications segment growth (data center fiber demand), and glass substrate/interposer volume for advanced packaging.

Mid-term (6-24mo)

Glass interposers could replace organic substrates in advanced packaging, enabling larger die sizes for AI chips. Optical fiber demand for intra- and inter-data center connectivity scales with GPU cluster size.

Catalysts

Q1 earnings 4/28
Glass substrate adoption by TSMC/Intel for packaging
Data center fiber demand growth

Risks

Glass substrate adoption timeline uncertain
Optical fiber is competitive market
Display segment cyclicality
