Owens Corning Inc. (NYSE:OC) shares are trading lower on Wednesday after the company reported its first-quarter 2025 results.

The company reported a 25% year-over-year growth in first-quarter net sales to $2.53 billion, beating the consensus of $2.51 billion.

Owens Corning's planned sale of its glass reinforcements unit remains on track for 2025, reinforcing its focus on building products. The business is now classified as discontinued, with reportable segments reorganized into roofing, Insulation, and doors.

Sales by segments: Roofing $1.12 billion (+2% YoY), Insulation $909 million (-5% YoY), and Doors $540 million.

Adjusted EBITDA increased to $565 million from $515 million, with a 22.3% margin (vs. 25.5% prior-year quarter). Adjusted EPS was $2.97, down from $3.40 a year ago, but above the consensus of $2.87.

Operating cash used for the quarter totaled $49 million, down from $24 million in cash provided, and free cash flow stood at negative $252 million.         

Owens Corning returned $159 million to shareholders via $59 million in dividends and $100 million in share buybacks, with 5.7 million shares still authorized for repurchase.

"The structural changes we have made to the company, combined with the capabilities of our team and the strength of our commercial and operational execution, continue to generate significant value for our customers and shareholders," said CEO Brian Chambers.

Owens Corning CFO Todd Fister expects the company to “drive long-term growth” while sustaining its structurally improved EBITDA margins and return cash to shareholders.

Outlook: For the second quarter, the company expects revenue to grow by high single digits over last year's $2.5 billion (excluding discontinued glass reinforcements).

The company anticipates delivering an adjusted EBITDA margin in the low-to-mid 20% range, supported by structural improvements and strong market positions.

For 2025, Owens Corning currently expects general EBITDA corporate expenses of around $240 million-$260 million and capital additions of ~$800 million.

Price Action: Ownes Corning shares are trading lower by 3.95% at $137 premarket on the last check Wednesday.
