Wendell P. Weeks, chairman and chief executive officer, said, “We delivered another excellent quarter. Year over year, core sales grew 14% to $4.27 billion, and core EPS grew 24% to $0.67. Overall, as we approach the second anniversary of Springboard, the plan has been a tremendous success. We have added $4 billion to our annualized sales run rate, and we have significantly improved our profitability – with an expected operating margin of 20% in the fourth quarter, a year ahead of plan.”

Weeks continued, “Beyond our strong third-quarter performance, we see significant growth ahead, fueled by powerful secular trends. To share just a few examples, we are ramping to meet remarkable demand for both our new Gen AI and U.S.-made solar products, and Apple’s recent $2.5 billion commitment to produce 100% of iPhone and Apple Watch cover glass at our Kentucky facility creates a larger, longer-term opportunity.”

Ed Schlesinger, executive vice president and chief financial officer, said, “Our outstanding third-quarter results reflect sales growth and margin expansion across multiple businesses. Year over year, core sales grew 14% while core operating margin expanded 130 basis points to 19.6%, core EPS grew 24%, and core ROIC grew 160 basis points to 13.4%. Additionally, we delivered strong adjusted free cash flow of $535 million. Overall, we continue to significantly enhance our returns as we execute Springboard.”

Schlesinger continued, “We expect continued strong growth in the fourth quarter, driven by ongoing robust demand for our Gen AI products and sales of solar wafers. We're guiding to core sales of approximately $4.35 billion, with core EPS growing faster than sales to a range of $0.68 to $0.72. Additionally, we are on track to achieve our Springboard operating margin target of 20% in the fourth quarter, a year ahead of plan. This represents a 370-basis-point improvement from our Q4-2023 starting point – and establishes a strong return profile as we continue to grow sales.”

Presentation of Information in this News Release

This news release includes non-GAAP financial measures. Non-GAAP financial measures are not in accordance with, or an alternative to, GAAP. Corning’s non-GAAP financial measures exclude the impact of items that are driven by general economic conditions and events that do not reflect the underlying fundamentals and trends in the company’s operations. The company believes presenting non-GAAP financial measures assists in analyzing financial performance without the impact of items that may obscure trends in the company’s underlying performance. Definitions of these non-GAAP financial measures and reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures can be found on the company’s website by going to the Investor Relations page and clicking “Quarterly Results” under the “Financials and Filings” tab. These reconciliations also accompany this news release.

With respect to the outlook for future periods, it is not possible to provide reconciliations for these non-GAAP measures because management does not forecast the movement of foreign currencies against the U.S. dollar, or other items that do not reflect ongoing operations, nor does it forecast items that have not yet occurred or are out of management’s control. As a result, management is unable to provide outlook information on a GAAP basis.
