Customer Deposits
As of June 30, 2025 and December 31, 2024, Corning had customer deposits of approximately $1.1 billion. Most of these customer deposits were non-refundable and allowed customers to secure rights to products produced under long-term supply agreements, generally over a period of up to ten years. As products are delivered to customers, Corning will recognize revenue and reduce the amount of the customer deposit liability.
For the three months ended June 30, 2025 and 2024, customer deposits recognized were $19 million and $11 million, respectively. For the six months ended June 30, 2025 and 2024, customer deposits recognized were $81 million and $91 million, respectively.

Deferred Revenue
As of June 30, 2025 and December 31, 2024, Corning had deferred revenue of approximately $763 million and $833 million, respectively. Deferred revenue was primarily related to the performance obligations of non-refundable consideration previously received by HSG from its customers under long-term supply agreements.
Deferred revenue is tracked on a per-customer contract-unit basis. As customers take delivery of the committed volumes under the terms of the contract, a per-unit amount of deferred revenue is recognized when control of the promised goods is transferred to the customer based upon the units delivered compared to the remaining contractual units. For the three and six months ended June 30, 2025 and 2024, the amount of deferred revenue recognized in the consolidated statements of income was not material.
