Use of Non-GAAP Measures

Owens Corning uses non-GAAP measures in its earnings press release that are intended to supplement investors' understanding of the company's financial information. These non-GAAP measures include EBITDA from continuing operations, adjusted EBITDA from continuing operations, adjusted earnings from continuing operations, adjusted diluted earnings per share attributable to Owens Corning common stockholders ("adjusted EPS") from continuing operations and free cash flow. When used to report historical financial information, reconciliations of these non-GAAP measures to the corresponding GAAP measures are included in the financial tables of this press release. Specifically, see Table 2 for adjusted EBITDA from continuing operations, Table 3 for adjusted earnings from continuing operations and adjusted EPS from continuing operations, and Table 8 for free cash flow.

For purposes of internal review of Owens Corning's year-over-year operational performance, management excludes from net earnings attributable to Owens Corning certain items it believes are not representative of ongoing operations. The non-GAAP financial measures resulting from these adjustments (including adjusted EBITDA from continuing operations, adjusted earnings from continuing operations and adjusted EPS from continuing operations) are used internally by Owens Corning for various purposes, including reporting results of operations to the Board of Directors, analysis of performance, and related employee compensation measures. Management believes that these adjustments result in a measure that provides a useful representation of its operational performance; however, the adjusted measures should not be considered in isolation or as a substitute for net earnings attributable to Owens Corning as prepared in accordance with GAAP.

Free cash flow is a non-GAAP liquidity measure used by investors, financial analysts and management to help evaluate the company's ability to generate cash to pursue opportunities that enhance shareholder value. The company defines free cash flow as net cash flow provided by operating activities, less cash paid for property, plant and equipment. Free cash flow is not a measure of residual cash flow available for discretionary expenditures due to the company's mandatory debt service requirements. Free cash flow is used internally by the company for various purposes, including reporting results of operations to the Board of Directors of the company and analysis of performance.

Management believes that these measures provide a useful representation of our operational performance and liquidity; however, the measures should not be considered in isolation or as a substitute for net cash flow provided by operating activities or net earnings attributable to Owens Corning as prepared in accordance with GAAP.

When the company provides forward-looking expectations for non-GAAP measures, the most comparable GAAP measures and a reconciliation between the non-GAAP expectations and the corresponding GAAP measures are generally not available without unreasonable effort due to the variability, complexity and limited visibility of the adjusting items that would be excluded from the non-GAAP measures in future periods. The variability in timing and amount of adjusting items could have significant and unpredictable effect on our future GAAP results.

The tax impact of adjusting items is based on our expected tax accounting treatment and rate for the jurisdiction of each adjusting item.

(d)

To compute adjusted earnings from continuing operations, we apply a full year pro forma effective tax rate to each quarter presented. For 2026, we have used a full year pro forma effective tax rate of 25%, which is the mid-point of our 2026 effective tax rate guidance of 24% to 26%. For comparability, in 2025, we have used an effective tax rate of 25%, which was our 2025 effective tax rate excluding the adjusting items referenced in (a), (b) and (c).
