Corning Incorporated · Response Dated July 25, 2025 · File No. 001-03247
We note your response to prior comment 1 regarding the constant-currency adjustment made in calculating your non-GAAP core performance measures. We also note that this adjustment is based on long-term management-determined rates, which are closely aligned with your hedging instrument rates. Please revise to remove this non-GAAP adjustment as it appears to be inconsistent with Rule 100(b) of Regulation G.
Company has engaged in an extensive written and verbal dialogue with the Staff regarding the constant-currency adjustment used in calculating its non-GAAP core performance measures, which utilizes core rates derived from the weighted average of the Company’s hedge rates.
The Company believes this adjustment has provided, and continues to provide, meaningful supplemental information to investors by illustrating operating performance within a stable currency environment similar to the environment established by the Company’s foreign currency risk management program.
However, the Company hasRead in the reply ↗Rest of the answer
considered the perspective communicated by the Staff during our ongoing discussions regarding the presentation of the constant-currency adjustment, specifically the Staff’s view that applying hedge-derived rates to total foreign currency exposure, where hedge coverage may be less than 100% could be inconsistent with Rule 100(b) of Regulation G. While the Company respectfully maintains that its presentation was not designed or intended to suggest that all foreign currency exposures were fully hedged, in future filings the Company will no longer use this non-GAAP adjustment.
Accordingly, as discussed with the Staff during a call on March 19, 2026, in future filings the Company will use a new non-GAAP adjustment as described and set forth in further detail below.
Proposed
New Presentation
Company continues to believe that it is useful to provide meaningful supplemental information to investors illustrating operating performance within the environment established by the Company’s foreign currency risk management program. The proposed new presentation will include a new non-GAAP adjustment for hedged exposures. In calculating its adjustment for hedged exposures, the Company will apply its hedge rates only to the hedged portion of its foreign currency exposure. The remaining unhedged portion will not be adjusted and will continue to be reflected at the exchange rates used in the Company's GAAP results during the reporting period. This results in non-GAAP core performance measures that include an adjustment for the hedged foreign currency exposure measured at hedge rates (the “hedged component”) and will not include an adjustment for the unhedged foreign currency exposure (the “unhedged component”), which remains fully reflected in such core measures in the same manner it is reflected in the most directly comparable GAAP measure.
The unhedged component is measured in accordance with ASC 830 and remains in the base GAAP numbers. Management believes the adjustment for hedged exposures provides investors with useful supplemental information regarding operating performance that is aligned with the environment established by the Company's foreign currency risk management program while providing transparency regarding the extent to which foreign currency exchange rate movements are mitigated by that program.
Company believes that this new presentation is responsive to the Staff’s concerns regarding Rule 100(b) of Regulation G. By limiting application of the adjustment to the hedged component and not adjusting the unhedged component, the revised presentation more precisely aligns the non-GAAP methodology with the scope of the Company's hedging program, consistent with the Company's existing disclosure that it may not be 100% hedged.

In addition to disclosure explaining the new presentation, in future filings, the Company will separately disclose, for each relevant foreign currency, the portion of underlying foreign currency exposure that is hedged under the Company's foreign currency risk management program for the period presented. As a result, the new presentation will include enhanced disclosure regarding the percentage of exposure hedged by currency, providing investors with direct visibility into the extent of hedge coverage, which underlies the new adjustment for hedged exposures.
treatment of other hedging-related adjustments in our core performance measures, including translation gains or losses on foreign-denominated debt and translated earnings contract gains or losses, remains consistent with prior practice. Specifically, the realized and unrealized gains or losses from our derivative and non-derivative hedging instruments are excluded from our core performance measures in our GAAP to core reconciliation because the adjustment for hedged exposures already reflects the underlying currency rates related to these instruments.
This ensures that the impact of these items is reflected only once and that there is no double counting between the adjustment for hedged exposures and these items.
For the Staff’s reference, pro forma example disclosure regarding the new presentation reflecting the Company’s proposed new adjustment is attached as Appendix A. Please note that in the interest of promptly responding to the Staff, certain estimates for the quarter ended March 31, 2026 have been used in the preparation of the illustrative excerpts in Appendix A as the Company’s first quarter financial books are not yet closed.
To provide the Staff with additional context for the pro forma adjustments for hedged exposures that you will see in the presentation set forth in Appendix A, we have also provided the tables below, which reflect the underlying calculations for the adjustments.
