Summary
Summary of the 8-K filed January 28, 2026. Cited figures are marked; the original filing is the authoritative source.
Corning Inc. (GLW) reported record fourth-quarter and full-year 2025 results on January 28, 2026, with core sales up 14% year over year to $4.41 billiona in Q4 and up 13% to $16.41 billion for the full year.
Core EPS rose 26% to $0.72b in Q4 and 29% to $2.52 for FY2025. GAAP results were also strong: Q4 sales of $4.22 billion (up 20% YoY), GAAP diluted EPS of $0.62 (up 72%), and FY2025 GAAP EPS of $1.83 (up 216%). Management emphasized margin and returns improvement since the Springboard plan launched: core operating margin expanded 390 bps to 20.2% and core ROIC rose 540 bps to 14.2% from Q4 2023 to Q4 2025, while adjusted free cash flow nearly doubled to $1.72 billion for FY2025.
The company also upgraded its Springboard plan. The internal plan now targets $11 billionc in incremental annualized sales by end-2028 (up from $8 billion), and the internal plan for end-2026 rose to $6.5 billion from $6 billion. The high-confidence plan for end-2026 increased to $5.75 billion from $4 billion.
Guidance for Q1 2026 calls for core sales of $4.2 to $4.3 billiond (about 15% YoY growth) and core EPS of $0.66 to $0.70. A multiyear agreement with Meta worth up to $6 billion, for data center technologies in the United States, was announced alongside the results. Segment performance was mixed.
Optical Communications was the clear driver, with FY2025 sales up 35% to $6.27 billion and net income up 71%. Specialty Materials, Automotive and Hemlock/Emerging Growth Businesses also grew, while Display (down 5%) and Life Sciences (down 1%) declined for the year. Investors should note that GAAP results include non-cash mark-to-market effects and constant-currency adjustments, and that the company's core measures exclude items such as restructuring, acquisition costs and litigation.
Q4 GAAP net income attributable to Corning was $540 million, and operating cash flow was $1.05 billion. Dividends paid in FY2025 were $999 million, and capital expenditures were $1.28 billion.

03—Questions
Frequently Asked Questions
Why do GAAP and core EPS differ so much, and which should investors focus on?
The gap comes from non-cash mark-to-market adjustments on translated earnings contracts and foreign-denominated debt, constant-currency adjustments, and items such as restructuring, acquisition-related costs, and litigation charges. Core EPS is management's preferred measure of ongoing operating performance and is used in compensation metrics. Investors should review both, since the GAAP figures include real charges and currency-related volatility that core metrics exclude.
What is the outlook for 2026 growth?
Management expects growth to accelerate in Q1 2026, with core sales up about 15% to $4.2–$4.3 billion and core EPS of $0.66–$0.70. The upgraded Springboard plan targets $6.5 billion of incremental annualized sales by end-2026 (internal plan) and $5.75 billion (high-confidence plan). Full-year 2026 guidance was not provided in this release.
How strong is Corning's cash generation and capital allocation?
FY2025 GAAP operating cash flow was $2.70 billion and adjusted free cash flow was $1.72 billion, nearly double the FY2023 level. Capital expenditures were $1.28 billion, and dividends paid totaled $999 million. Corning also repurchased $163 million of stock for treasury during the year. Debt rose to about $8.4 billion, including finance lease principal payments.
What is driving the business, and which segments are weaker?
Optical Communications is the main growth engine, with FY2025 sales up 35% to $6.27 billion and net income up 71%, supported by data center demand and the Meta agreement. Specialty Materials (up 10%) and Hemlock and Emerging Growth Businesses (up 33%) also grew. Display (down 5%) and Life Sciences (down 1%) were the weaker segments for the year, and Automotive declined 3%.
What is the Meta agreement and why does it matter?
Corning announced a multiyear agreement with Meta worth up to $6 billion to develop, innovate, and manufacture technologies for next-generation U.S. data centers. The deal supports the company's Optical Communications growth thesis and the upgraded Springboard targets. The release does not specify the timing or revenue recognition schedule, so investors should look for further detail on the contract's phasing and profitability.
