Sources: Figures are from Corning's Q4/Full-Year 2025 earnings release (January 2026) and its FY2025 Form 10-K, both company-disclosed. Segment sales are reported by Corning on a 'core' (non-GAAP) basis in the earnings release; GAAP consolidated net sales for FY2025 were $15,629 million. No credible, specifically-sourced third-party market-share estimate for Corning's core businesses (optical fiber, display glass, cover glass) was found, so no market-share figure is included. Because one segment (Hemlock and Emerging Growth Businesses) posted a segment net loss in FY2025, segment profitability is shown only in the KPI table, not as a pie.
