Corning Reports Fourth-Quarter and Full-Year 2023 Financial Results

CORNING, N.Y., Jan. 30, 2024 (GLOBE NEWSWIRE) --  

Corning Incorporated (NYSE: GLW) today announced its fourth-quarter and full-year 2023 results and provided its outlook for first-quarter 2024.

Wendell P. Weeks, chairman and chief executive officer, said, “Overall, our results in the quarter – and throughout 2023 – demonstrate that we continue to make solid progress advancing our market leadership, strengthening our profitability, and improving our cash-flow generation even in the lower-demand environment we’ve experienced.”

Weeks continued, “We are entering 2024 operationally strong, and we have an opportunity to increase our sales by more than $3 billion in the medium term as our markets normalize. As we capture that growth, we expect to deliver powerful incremental profit and cash flow – which is a terrific opportunity for our shareholders.”

Financial Review

Fourth-Quarter 2023:

  • GAAP sales were $3.0 billion, down 6% sequentially. Core sales were $3.3 billion, down 5% sequentially, in line with expectations.
  • GAAP EPS was $(0.05), and core EPS was $0.39. The difference between GAAP and core EPS primarily reflected constant currency adjustments, translated earnings contract gains, and translation losses on Japanese-yen-denominated debt, as well as restructuring and asset write-off charges.
  • Year over year, GAAP gross margin improved by 350 basis points and core gross margin improved by 330 basis points while GAAP and core sales declined 12% and 10%, respectively.
  • Cash flow continued to improve: GAAP operating cash flow was $713 million, and adjusted free cash flow was $487 million.

Full-Year 2023:

  • GAAP sales were $12.6 billion, down 11%. Core sales were $13.6 billion, down 8%.
  • GAAP EPS was $0.68, and core EPS was $1.70. The difference between GAAP and core EPS primarily reflected constant currency adjustments, translated earnings contract gains, and translation gains on Japanese-yen-denominated debt, as well as restructuring and asset write-off charges.
  • GAAP operating cash flow was $2 billion, and adjusted free cash flow was $880 million.

First-Quarter 2024 Outlook:

  • Management expects first-quarter core sales of approximately $3.1 billion and core EPS in the range of $0.32 to $0.38 and anticipates the first quarter to be the low quarter of the year.

Ed Schlesinger, executive vice president and chief financial officer, said, “In the fourth quarter, we grew core gross margin by 330 basis points versus the fourth quarter of 2022, and adjusted free cash flow improved to $487 million. Our results in the quarter – and throughout 2023 – reflect the benefits of our actions to increase price, improve our productivity ratios, and reduce inventory.”

Schlesinger continued, “For the first quarter of 2024, we expect core sales of approximately $3.1 billion and EPS in the range of $0.32 to $0.38. We anticipate the first quarter to be the low quarter of the year and to drive profitable, durable growth over the long term.”

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: 

  • Continuing to set the standard for durable, high-performance smartphone cover materials. Corning continued its legacy of innovation with its Corning® Gorilla® Armor, a new cover material featured on Samsung’s Galaxy S24 Ultra. Gorilla Armor offers an unparalleled combination of durability and visual clarity, delivering a richer display in sunlight and greater protection against damage caused by daily wear. 

  • Advancing optical innovations in broadband, 5G, cloud computing, and advanced AI. Corning’s Jeffrey Evenson, executive vice president and chief strategy officer, along with Aleksandra Boskovic, vice president of technology development, Optical Communications, shared how Corning’s optical fiber innovations and unique value proposition position the company to capitalize on opportunities in telecommunications, cloud computing, and advanced artificial intelligence. To learn more, see Corning’s feature in Bloomberg Intelligence’s Tech Disruptors podcast.

  • Advancing the driving experience by creating the next generation of automotive-interior displays. Collaboration among Corning, display leader Tianma, and automaker GAC incorporates Corning’s award-winning LivingHingeTechnology, which was named a 2024 “Best of Innovation Honoree” by CES® for enabling the display to dynamically bend. Also at CES, Corning unveiled its latest cockpit innovation alongside longtime collaborator BOE Technology Group Co. Ltd. It features a 44.6-inch ultra-large oxide panel with Corning® ColdForm™ Technology, which touts an independently verified lower environmental impact of at least 25%.

  • Helping automakers turn windows into system-enabling components. A recent MotorTrend article featured Corning’s new Fusion5™ Glass, which delivers windshields with superior durability, better optical performance, and lighter weight than conventional windshields. The innovative windshield technology helps enable the sensor systems needed for Advanced Driver Assistance Systems and higher levels of autonomy, while providing weight savings needed to extend electric vehicle range.

  • Continuing its dedication to providing an equitable workplace. For the second year in a row, Corning received a score of 100 on the Human Rights Campaign Foundation’s Corporate Equality Index.

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.
