Owens Corning's Q1 2026 results show a substantial deterioration in financial performance, confirming the previously reported quarterly loss. Net sales decreased by 10.5% year-over-year, and operating income plummeted by approximately 70%. The company's net loss attributable to Owens Corning widened to $105 million, primarily driven by a $182 million pre-tax loss from the amendment to the Glass Reinforcements (GR) business sale. This divestiture, which closed on April 30, 2026, saw a $110 million reduction in purchase price and the elimination of $225 million in promissory notes, indicating less favorable terms than initially expected.
