Capital Deployment and Liquidity

On February 3, Owens Corning announced that its Board of Directors declared a quarterly cash dividend of $0.35 per common share, a 35% increase compared with the same period in 2020.
On February 14, Owens Corning's Board of Directors approved a share repurchase authorization for up to 10 million shares of the company's common stock. This was in addition to its previously announced share buyback program which had 3.4 million shares available for repurchase under the prior authorization as of the end of 2021.

"Earnings expansion along with our ongoing disciplined management of working capital, operating expenses, and capital investments drove record free cash flow generation in 2021 of $1.1 billion and conversion of 112%," said Executive Vice President and Chief Financial Officer Ken Parks. "During the year, we returned 62% of free cash flow to shareholders through dividends and share repurchases. Our strong and consistent cash generation combined with our solid investment-grade balance sheet support the execution of our growth strategy and delivery of our three-year financial targets outlined during our recent Investor Day."

2021 Segment Performance

Full-Year

Composites net sales increased 19% to $2.3 billion in 2021 compared with 2020, primarily due to the favorable impact of customer mix, higher selling prices, and higher sales volumes. EBIT increased $211 million to $376 million, with 16% EBIT margins, on improved production leverage and higher selling prices, which more than offset inflation and increased transportation costs.
Insulation net sales increased 22% to $3.2 billion compared with 2020, given higher sales volumes and selling prices. EBIT increased $196 million to $446 million, with 14% EBIT margins, on higher selling prices, which more than offset inflation and increased transportation costs, as well as higher sales volumes and the benefit of improved production leverage.
Roofing net sales increased 19% to $3.2 billion compared with 2020, mainly due to higher selling prices and sales volumes on higher shingle and components shipments. EBIT increased $162 million to $753 million, with 23% EBIT margins, on higher sales volumes and higher selling prices, which more than offset input cost inflation, primarily asphalt and other petroleum-based products, and increased transportation costs.

Fourth-Quarter

Composites net sales increased 11% to $608 million in fourth-quarter 2021 compared with fourth-quarter 2020, primarily due to higher selling prices and the favorable impact of customer mix. EBIT increased $38 million to $98 million, with 16% EBIT margins, on favorable mix, improved production leverage, and higher selling prices, which more than offset inflation and increased transportation costs.
Insulation net sales increased 19% to $863 million in fourth-quarter 2021 compared with fourth-quarter 2020, given higher selling prices and sales volumes. EBIT increased $22 million to $128 million, with 15% EBIT margins, on higher sales volumes and selling prices, which more than offset inflation and increased transportation costs.
Roofing net sales increased 1% to $712 million in fourth-quarter 2021 compared with fourth-quarter 2020, with higher selling prices largely offset by lower sales volumes and unfavorable product mix. EBIT decreased $32 million to $151 million, with 21% EBIT margins, primarily due to lower sales volumes and unfavorable product mix with higher selling prices offsetting input cost inflation, primarily asphalt and other petroleum-based products, and increased transportation costs.

Other Key Highlights

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 EBIT, adjusted EBIT, EBITDA, adjusted EBITDA, adjusted earnings, adjusted diluted earnings per share attributable to Owens Corning common stockholders ("adjusted EPS"), adjusted pre-tax earnings, free cash flow and free cash flow conversion. 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 EBIT, adjusted EBIT, EBITDA and adjusted EBITDA, Table 7 for adjusted earnings and adjusted EPS, 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 EBIT, adjusted EBITDA, adjusted earnings, adjusted EPS and adjusted pre-tax earnings) 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. Free cash flow is not a measure of residual cash flow available for discretionary expenditures due to the company's mandatory debt service requirements. As a conversion ratio, free cash flow is compared to adjusted earnings. Free cash flow and free cash flow conversion are 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.

(a)	Please refer to Table 2 "EBIT Reconciliation Schedules" for additional information on adjusting items.
(b)	The tax impact of adjusting items is based on our expected tax accounting treatment and rate for the jurisdiction of each adjusting item.
(c)	There were no significant tax items in 2021. For comparability, significant tax items in 2020 include the impact of a change in valuation allowances recorded against certain deferred tax assets, a change in estimate related to finalized regulations on global intangible low-taxed income (GILTI), part of the U.S. Tax Cuts and Jobs Act of 2017, and the recognition of a deferred tax asset resulting from the transfer of certain intellectual property rights held by wholly owned foreign subsidiaries to the U.S.
(d)	To compute adjusted earnings, we apply a full year pro forma effective tax rate to each quarter presented. For 2021, we have used an effective tax rate of 24%, which was our 2021 effective tax rate excluding the adjusting items referenced in (a), (b) and (c). For comparability, in 2020, we have used an effective tax rate of 24%, which was our 2020 effective tax rate excluding the adjusting items referenced in (a), (b) and (c).
