Management reaffirms expectation that first-quarter sales will mark the low point of the year, as improving market conditions support higher sales throughout 2024

Management expects core sales to grow sequentially to approximately $3.4 billion in the second quarter of 2024, with core EPS in the range of $0.42 to $0.46

Corning is well positioned to add more than $3 billion in annualized sales – and deliver strong incremental profit and cash flow – as markets continue to improve

Corning Incorporated (NYSE:GLW) today announced its first-quarter 2024 results and provided its outlook for second-quarter 2024.

Wendell P. Weeks, chairman and chief executive officer, said, "Our first-quarter results were at the high end of our guidance. Importantly, we're seeing encouraging signs of improving market conditions. We continue to expect that the first quarter will be the low quarter for the year."

Weeks continued, "We are executing our plans to add more than $3 billion in annualized sales within the next three years, and we already have the required capacity and capabilities in place. As a result, we are poised to deliver powerful incremental profit and cash flow and generate substantial shareholder value."

First-Quarter 2024 Financial Highlights:

GAAP sales were $2.98 billion. Core sales were $3.26 billion. Year over year, GAAP and core sales declined by 6% and 3%, respectively.
Profitability improved despite the lower sales, reflecting the continued benefit of pricing and productivity improvement actions. Year over year, GAAP gross margin improved by 180 basis points and core gross margin improved by 160 basis points.
GAAP EPS was $0.24, and core EPS was $0.38. The difference between GAAP and core EPS primarily reflected constant-currency adjustments, translated earnings contract gains, and translation gains on Japanese-yen-denominated debt.
GAAP operating cash flow was $96 million, and adjusted free cash flow was $(62) million – both significantly improved versus the first quarter of 2023.

Second-Quarter 2024 Outlook:

For the second quarter, management expects core sales to grow to approximately $3.4 billion, with core EPS in the range of $0.42 to $0.46.

Ed Schlesinger, executive vice president and chief financial officer, said, "Our actions to increase price and improve our productivity ratios are paying off. In the first quarter, despite lower year-over-year core sales, we grew core gross margin by 160 basis points. We also grew adjusted free cash flow by more than $300 million versus the first quarter of 2023."

Schlesinger continued, "Overall, we have established a significantly stronger profitability and cash flow base, and we expect to grow from first-quarter levels. In the second quarter, we expect core sales of approximately $3.4 billion, with core EPS in the range of $0.42 to $0.46."

Strategy in Action

Corning strives to be a catalyst for positive change and to help move the world forward. The company drives profitable multiyear growth by inventing, making, and selling life-changing products while cultivating deep, trust-based relationships with industry leaders, ultimately incorporating more content into customers' offerings. Corning takes the long view, investing in a set of vital capabilities that are increasingly relevant to profound transformations that touch many facets of daily life. Today, Corning's markets include optical communications, mobile consumer electronics, display, automotive, solar, semiconductor, and life sciences.

Recent highlights include:

Advancing "More Corning" content opportunities by helping automakers meet ever-tightening pollution standards to produce cleaner vehicles. The U.S. Environmental Protection Agency's final multipollutant tailpipe emissions standards for cars and trucks, announced in March, include a strong particulate emissions limit that will require the deployment of gasoline particulate filters in the U.S. for all gasoline vehicles, including hybrids, beginning in 2027. Corning is the inventor of and clear market leader in GPFs, and the new regulations add two to three times the opportunity for emissions-control content in gasoline vehicles, including hybrids.

Innovating to enable faster deployments and higher-density solutions needed for fiber-rich networks supporting growth in broadband, 5G, and generative AI. Corning introduced RocketRibbon® cable with Flow Ribbon Technology, featuring a 60% reduction in cable diameter. Smaller, denser cables are ideal for solving the AI-driven infrastructure challenges of carrier and data center customers. Corning also launched its latest connectivity advancement, Multifiber Pushlok™ Technology, with innovative features that make it faster, easier, and up to $25 less expensive per home to deploy optical fiber and expand broadband access. In related media coverage, a recent CBS News "60 Minutes" segment featuring U.S. Secretary of Commerce Gina Raimondo and Corning Chairman and CEO Wendell P. Weeks spotlighted Corning's collaboration with the White House to bring high-speed internet to underserved rural communities as part of the Broadband Equity Access and Deployment (BEAD) program. The industry expects funding approvals to begin late this year, leading to spending in 2025. Corning anticipates BEAD-related projects will add significantly to the company's addressable market.

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.

CORE PERFORMANCE MEASURES

In managing the Company and assessing our financial performance, we adjust certain measures included in our consolidated financial statements to exclude specific items to arrive at our core performance measures. These items include the impact of translating the Japanese yen-denominated debt, the impact of the translated earnings contracts, acquisition-related costs, certain discrete tax items and other tax-related adjustments, restructuring, impairment and other charges and credits, certain litigation, regulatory and other legal matters, pension mark-to-market adjustments and other items which do not reflect the ongoing operating results of the Company.

In addition, because a significant portion of our revenues and expenses are denominated in currencies other than the U.S. dollar, management believes it is important to understand the impact on sales and net income of translating these currencies into U.S. dollars. Therefore, management utilizes constant-currency reporting for the Display Technologies, Specialty Materials, Environmental Technologies and Life Sciences segments to exclude the impact from the Japanese yen, South Korean won, Chinese yuan, New Taiwan dollar and euro, as applicable to the segment. In addition, effective January 1, 2024, the Company began utilizing constant-currency reporting for the Optical Communications segment to exclude the impact from the Mexican peso on segment results. Prior periods were not recasted as the impact was not material. The most significant constant-currency adjustment relates to the Japanese yen exposure within the Display Technologies segment.

The constant-currency rates established for our core performance measures are internally derived long-term management estimates, which are closely aligned with our hedging instrument rates. These hedging instruments may include, but are not limited to, foreign exchange forward or option contracts and foreign-denominated debt. For details of the rates used, please see the footnotes to the "Reconciliation of Non-GAAP Measures" section. We believe that the use of constant-currency reporting allows management to understand our results without the volatility of currency fluctuations, analyze underlying trends in the businesses and establish operational goals and forecasts.

Core performance measures are not prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). We provide investors with these non-GAAP measures to evaluate our results as we believe they are indicative of our core operating performance and provide greater transparency to how management evaluates our results and trends and makes financial and operational decisions. These measures are not, and should not be viewed as a substitute for, GAAP reporting measures. 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.

*Items Adjusted from GAAP Measures*

Items adjusted from GAAP measures to arrive at core performance measures are as follows:

(1)	Constant-currency adjustment: As a significant portion of revenues and expenses are denominated in currencies other than the U.S. dollar, management believes it is important to understand the impact on sales and net income of translating these currencies into U.S. dollars. The Company utilizes constant-currency reporting for Display Technologies, Specialty Materials, Environmental Technologies and Life Sciences segments for the Japanese yen, Korean won, Chinese yuan, New Taiwan dollar and euro, as applicable to the segment. In addition, effective January 1, 2024, the Company began utilizing constant-currency reporting for the Optical Communications segment to exclude the impact from the Mexican peso on segment results. Prior periods were not recasted as the impact was not material. The constant-currency rates established for our core performance measures are internally derived long-term management estimates, which are closely aligned with our hedging instrument rates. These hedging instruments may include, but are not limited to, foreign exchange forward or option contracts and foreign-denominated debt. For the three months ended March 31, 2024, the adjustment primarily relates to our Japanese yen exposure due to the difference in the average spot rate compared to our core rate. We believe that the use of constant-currency reporting allows management to understand our results without the volatility of currency fluctuation, analyze underlying trends in the businesses and establish operational goals and forecasts. Constant-currency rates used are as follows and are applied to all periods presented and to all foreign exchange exposures during the period, even though we may be less than 100% hedged:

Korean won

(2)	Translation of Japanese yen-denominated debt: Amount reflects the gain or loss on the translation of our yen-denominated debt to U.S. dollars.
(3)	Translated earnings contract: Amount reflects the impact of the realized and unrealized gains and losses from the Japanese yen, South Korean won, Chinese yuan, euro and New Taiwan dollar-denominated foreign currency hedges related to translated earnings, as well as the unrealized gains and losses of our British pound-denominated foreign currency hedges related to translated earnings.
(4)	Acquisition-related costs: Amount reflects intangible amortization, inventory valuation adjustments and external acquisition-related deal costs, as well as other transaction related costs.
(5)	Discrete tax items and other tax-related adjustments: Amount reflects certain discrete period tax items such as changes in tax law, the impact of tax audits, changes in tax reserves and changes in deferred tax asset valuation allowances, as well as other tax-related adjustments.
(6)	Restructuring, impairment and other charges and credits: Amount reflects certain restructuring, impairment losses and other charges and credits, as well as other expenses, including severance, accelerated depreciation, asset write-offs and facility repairs resulting from power outages, which are not related to ongoing operations.
(7)	Litigation, regulatory and other legal matters: Amount reflects developments in commercial litigation, intellectual property disputes, adjustments to our estimated liability for environmental-related items and other legal matters.
(8)	Pension mark-to-market adjustment: Amount primarily reflects defined benefit pension mark-to-market gains and losses, which arise from changes in actuarial assumptions and the difference between actual and expected returns on plan assets and discount rates.
(9)	Loss on investments: Amount reflects the gain or loss recognized on investments due to mark-to-market adjustments for the change in fair value or the disposition of an investment.
(10)	Gain on sale of assets: Amount represents the gain recognized for the sale of assets.
