Future Outlook

Owens Corning anticipates near-term market demand for non-discretionary roofing repair activity to decline in the third quarter of 2025 due to lower storm activity, though demand for its products is expected to outpace the market. Residential new construction and remodeling are projected to remain challenged, while non-residential construction activity in North America is expected to remain relatively stable. Market conditions in Europe are anticipated to gradually improve in the second half of the year. The company expects minimal third-quarter impact from tariff exposure, reducing its approximately $50 million exposure to a net impact of about $10 million, primarily in the Doors business. For Q3 2025, the company expects revenue from continuing operations to be slightly down to in-line with prior year, approximately $2.7 billion to $2.8 billion, and an adjusted EBITDA margin from continuing operations of approximately 23% to 25%. The divestiture of the glass reinforcements business remains targeted for completion in 2025.

Management Comments

• Chair and Chief Executive Officer Brian Chambers stated, "Our second quarter results continue to demonstrate the strength of our business and resiliency of our earnings to outperform the market despite more challenging near-term conditions. This is the result of the structural changes and strategic choices we have made to reshape the new Owens Corning. As we progress through the year, we remain focused on leveraging our unique operating model to strengthen our market positions, sustain our financial performance, and create value for our customers and shareholders."
• Executive Vice President and Chief Financial Officer Todd Fister commented, "Owens Corning demonstrated strong execution in a softening North America residential market, delivering a milestone 20th consecutive quarter of 20% or better adjusted EBITDA margins. With confidence in our cash generation, we returned significant cash to shareholders – nearly $440 million in the first half – and remain on track to deliver our commitment of $2 billion in returns over the next two years. Even in current market conditions, we expect to maintain strong EBITDA margins and shareholder returns while investing to accelerate long-term growth and incremental cash generation."

Industry Context

The company's performance is set against a backdrop of mixed market conditions, including a softening North America residential market, declining non-discretionary roofing repair activity due to lower storm activity, and challenged residential new construction and remodeling. Despite these headwinds, Owens Corning's ability to increase net sales and earnings, and maintain strong adjusted EBITDA margins, suggests effective operational execution and commercial strength relative to broader industry trends. The expected gradual improvement in European market conditions in the second half of the year could provide some tailwind, while the stability in North American non-residential construction offers a consistent demand segment.

Comparison to Industry Standards

• The filing does not provide specific comparable companies, projects, or results to benchmark against industry standards. However, the company's achievement of its 20th consecutive quarter of 20% or better adjusted EBITDA margins suggests a sustained level of operational efficiency and profitability that is likely competitive within the building products sector, particularly given the 'mixed market environment' and 'softening North America residential market' mentioned by management.

Corporate Governance

Stakeholder Impact

• Shareholders: Positively impacted by strong earnings growth, significant cash returns through dividends and share repurchases, and a new share repurchase authorization, signaling management's confidence and commitment to shareholder value.
• Employees: The company maintained a high level of safety performance (RIR of 0.60), indicating a continued focus on employee well-being.
• Customers: The company aims to strengthen market positions and create value for customers, suggesting continued focus on product and service delivery.
• Creditors: The level of indebtedness and liquidity are mentioned as risk factors, which could impact creditors, though the company's cash generation confidence suggests manageable debt service.

Next Steps

• Continue leveraging the unique operating model to strengthen market positions and sustain financial performance.
• Progress with the divestiture of the glass reinforcements business, targeting completion in 2025 subject to regulatory approvals.
• Deliver on the commitment to return $2 billion of cash to shareholders over 2025 and 2026.

Key Dates

Recommendation

Owens Corning's Q2 2025 results demonstrate robust top-line and bottom-line growth, with net sales up 10% and net earnings up 30%. The company's ability to maintain a 20th consecutive quarter of 20%+ adjusted EBITDA margins underscores its operational resilience and efficiency, even in a 'mixed market environment.' While operating and free cash flow saw significant declines, management's strong commitment to return $2 billion to shareholders over 2025-2026, coupled with a new share repurchase authorization, signals high confidence in future cash generation and a proactive approach to capital allocation. Strategic divestitures are progressing, streamlining the portfolio. Despite near-term market challenges in residential construction, the company's market-leading positions and structural improvements position it well for sustained performance and long-term value creation, making it an attractive 'buy' for investors with a long-term horizon.
