Ferroglobe PLC (GSM) saw its stock price plummet 7.10% in after-hours trading on Wednesday, following the release of its third-quarter financial results for 2025. The significant drop suggests that investors were disappointed with the company's performance.

According to the earnings report, Ferroglobe's Q3 sales came in at $311.7 million, representing a substantial 19.4% decrease from the previous quarter and a concerning 28.1% decline compared to the same period last year. The company's adjusted EBITDA for the quarter was $18.3 million, with an adjusted EBITDA margin of 11.7%. These figures indicate a challenging operating environment for the silicon and specialty metals producer.

Despite the weak results, Ferroglobe reported some positive developments. The company declared a dividend of $0.014 per share, payable on December 29, 2025, to shareholders of record as of December 22, 2025. Additionally, Ferroglobe highlighted progress in a preliminary U.S. silicon metal trade case and expectations for a final EU safeguard decision by November 18. The company also announced a joint development agreement with Coreshell to advance silicon anode technology in EV batteries, with pilot deliveries already underway. However, these developments were not enough to offset investor concerns about the company's overall financial performance, leading to the sharp after-hours decline.
