Cooper-Standard Holdings Inc. (CPS) saw its stock price plummet 8.11% in pre-market trading on Friday, as investors reacted to the company's third-quarter financial results. Despite showing some improvements, the auto parts manufacturer still reported a net loss, disappointing market expectations.

The company announced a net loss of $7.6 million for Q3 2025, an improvement from the $11.1 million loss in the same period last year. While the net loss margin improved to -1.1% from -1.6%, the continued losses appear to have spooked investors. Cooper-Standard's sales for the quarter reached $695.5 million, a slight increase from $685.4 million in Q3 2024.

Despite the negative bottom line, there were some positive takeaways from the report. The company's adjusted EBITDA for Q3 2025 increased to $53.3 million, up from $46.1 million in the previous year, with the adjusted EBITDA margin rising to 7.7% from 6.7%. However, these improvements were not enough to offset concerns about the company's ongoing profitability challenges, leading to the significant pre-market sell-off.
