Business Segment Analysis

Roofing

Financial Performance:

• Revenue: $4.437 billion (-4.2% YoY)
• EBITDA: $1.411 billion (-7.9% YoY)
• Operating Margin (EBITDA as % of net sales): 32% (2025), 33% (2024)
• Key Growth Drivers: Lower sales volumes (approximately 7%) were partially offset by higher selling prices ($129 million). EBITDA was impacted by lower volumes, input cost inflation ($52 million), and higher manufacturing costs ($20 million), partially offset by higher selling prices ($129 million). Unfavorable mix, higher selling, general, and administrative expenses, and higher delivery costs ($7 million) also contributed to the decline.

Product Portfolio: Primary products include laminate asphalt roofing shingles, roofing components, composite lumber, and oxidized asphalt, mainly for residential construction. The segment also manufactures and sells glass mat and specialty veil materials for building and construction applications.

Market Dynamics: Demand is primarily driven by residential repair and remodeling activity and new residential construction. Major storm damage can significantly increase demand. Owens Corning is the second largest producer of asphalt roofing shingles in the United States, competing on innovation, product design, breadth of offering, customer proximity, quality, and price. The Company expects non-discretionary roof replacement activity to ease in the near-term, with global non-residential construction markets remaining relatively stable.

Insulation

Financial Performance:

• Revenue: $3.700 billion (-5.8% YoY)
• EBITDA: $0.848 billion (-10.3% YoY)
• Operating Margin (EBITDA as % of net sales): 23% (2025), 24% (2024)
• Key Growth Drivers: The decrease in net sales was primarily due to lower sales volumes (approximately 5%), a $68 million unfavorable impact from the divestiture of the building materials business in China and Korea, and slightly unfavorable mix. These were partially offset by favorable selling prices ($27 million) and a $23 million favorable foreign currency translation impact. EBITDA was driven down by lower sales volumes, production downtime ($50 million), and input cost inflation ($42 million), partially offset by lower manufacturing costs ($30 million), higher selling prices ($27 million), and favorable mix.

Product Portfolio: Offers a diverse portfolio including thermal and acoustical batts, loosefill insulation, spray foam insulation, wet use chopped strand, foam sheathing, and accessories under brands like Owens Corning PINK® Next Gen™ FIBERGLAS™ Insulation. Non-residential products include glass fiber pipe insulation, flexible duct media, stone wool insulation, cellular glass insulation, and foam insulation under brands like FOAMULAR®, FOAMGLAS®, and Paroc®.

Market Dynamics: Demand is influenced by North American new residential construction, repair and remodeling, non-residential construction in the United States, Canada, Europe, and Latin America, and increasingly stringent building codes for energy efficiency.

The North American residential new construction market is expected to remain challenged in the near-term due to mortgage rates, while global non-residential construction markets are anticipated to be relatively stable.

Doors

Financial Performance:

• Revenue: $2.125 billion (+46.8% YoY)
• EBITDA: $0.232 billion (0.0% YoY)
• Operating Margin (EBITDA as % of net sales): 11% (2025), 16% (2024)
• Key Growth Drivers: The significant increase in net sales was primarily due to the acquisition of Masonite on May 15, 2024. This was partially offset by lower volumes (approximately 8%) and lower selling prices ($3 million), with slightly favorable mix. EBITDA remained flat, as the benefit from the Masonite acquisition, lower selling, general, and administrative expenses, and favorable mix were offset by higher input cost inflation ($43 million), lower volumes, unfavorable manufacturing performance ($20 million), and lower selling prices ($3 million).

Product Portfolio: Manufactures and sells residential interior and exterior doors made of wood, glass, fiberglass, and metal, along with door components (frames, sills, weather-stripping, hinges, locks). The segment also offers aluminum-framed glass doors and window solutions for luxury homes.

Market Dynamics: Demand is driven by new residential construction and residential repair and remodeling markets in North America and Europe. Owens Corning is one of North America’s largest producers of interior and exterior doors. The Company expects the North America residential new construction market and discretionary residential repair and remodeling activity to remain soft in the near-term due to a weak macroeconomic outlook.

Business Cyclicality & Seasonality

Demand Patterns: Demand for Owens Corning's products is largely cyclical, influenced by residential and non-residential construction activity, which is sensitive to economic conditions, interest rates, and consumer confidence. Roofing demand is also significantly affected by major storms. While insulation and doors demand generally follows seasonal home improvement and construction patterns, roofing sales do not always align due to storm-related demand. The peak season for home construction and remodeling typically occurs in the second and third calendar quarters.

Economic Sensitivity: Construction activity is influenced by prevailing economic conditions, including interest rates, inflation, employment levels, and consumer spending. Demand for residential insulation is closely correlated to U.S. housing starts (with a three-month lag), and non-residential demand correlates with industrial production growth.

Industry Cycles: The construction industry, which drives a large portion of the Company's product demand, is historically cyclical.

Regulatory Environment & Compliance

Regulatory Framework: Owens Corning's manufacturing facilities are subject to extensive foreign, federal, state, and local laws and regulations concerning hazardous materials, pollution (air emissions, water discharges, waste management), and environmental protection. The Company also complies with competition laws (e.g., Sherman Antitrust Act), health and safety regulations, data privacy and security laws, and regulations related to product and chemical hazards, including climate change impacts.

Trade & Export Controls: The Company's global operations are subject to trade regulations, including tariffs and import/export restrictions, which can increase costs, limit market access, and disrupt supply chains. Compliance with U.S. and foreign export and trading laws, including sanctions, is required.

Legal Proceedings: Owens Corning is involved in various legal and regulatory proceedings, including environmental remediation at 25 sites worldwide (10 Superfund/equivalent, 15 owned/formerly owned sites). A material product recall in 2023 by its subsidiary, Paroc Group OY, for marine insulation products not meeting fire safety requirements, and ongoing assessment of other potential nonconformances, represents a significant legal and reputational risk.

Tax Strategy & Considerations

Tax Profile: Owens Corning's effective tax rate for 2025 was 282% on pre-tax income of $104 million, primarily driven by non-deductible goodwill impairment, U.S. state and local income tax expense, and foreign tax effects. In 2024, the effective tax rate was 26% on pre-tax income of $1,275 million, mainly due to U.S. state and local income tax expense. The Company asserts indefinite reinvestment for the majority of its foreign subsidiaries' undistributed reserves, totaling approximately $1.1 billion as of December 31, 2025, and has not provided for withholding or income taxes on these amounts.

Insurance & Risk Transfer

Risk Management Framework: Owens Corning maintains processes to identify and mitigate enterprise risks. The Company holds insurance coverage for some potential claims, including product liability, but acknowledges that coverage may not be adequate for all claims. It also uses financial contracts and derivative financial instruments, such as natural gas forward swap contracts, to hedge a portion of its near-term exposure to commodity price fluctuations and foreign currency exchange rate risks.
