SunCoke Energy (SXC) shares plummeted 6.22% in pre-market trading on Wednesday following the release of its disappointing second-quarter 2025 financial results. The company's earnings fell significantly short of analyst expectations, prompting investor concerns about its near-term performance.

The coke producer reported quarterly earnings of $0.02 per share, missing the analyst consensus estimate of $0.17 by a wide margin. This represents a 92% decrease from earnings of $0.25 per share in the same period last year. SunCoke's net income attributable to shareholders dropped to $1.9 million, down from $21.5 million in Q2 2024. The company's revenue also declined 7.8% year-over-year to $434.1 million, although this figure beat analyst estimates of $348.05 million.

SunCoke Energy's CEO, Katherine Gates, attributed the weak performance to the timing and mix of contract and spot coke sales in the Domestic Coke segment, as well as lower transloading volumes at the Convent Marine Terminal due to challenging market conditions. Despite the disappointing quarter, the company reaffirmed its full-year 2025 adjusted EBITDA guidance of $210 million to $225 million, expecting improved coke sales mix in the second half of the year. Additionally, SunCoke announced that all regulatory approvals have been received for its Phoenix Global acquisition, which is expected to close on August 1, potentially diversifying its customer base and enhancing its capabilities as a supplier to steelmaking customers.
