Superior Industries International, Inc. reports sharply weaker results and major capital structure changes for the quarter and nine months ended September 30, 2025. Net sales were $178.2 million for the quarter and $707.7 million for the nine months, compared with $321.8 million and $957.0 million a year earlier. The company posted a quarterly net loss of $84.99 million and a nine‑month net loss of $278.97 million, driven by negative gross margins, higher interest expense and a $66.9 million impairment of North America long‑lived assets.
Operating cash flow was a use of $72.1 million for the nine months, while debt financing increased cash by $107.1 million, including new short‑term and term borrowings. Total debt liabilities were $662.2 million, with most maturing in 2025 and a large portion of preferred stock classified as mezzanine equity. Management discloses that customer resourcing actions affecting roughly one‑third of projected 2025 sales, covenant violations as of September 30, 2025, and tight liquidity raise substantial doubt about the company’s ability to continue as a going concern.
