Shares of Donnelley Financial Solutions, Inc. (DFIN) plummeted 5.16% in pre-market trading on Wednesday following the release of its third-quarter 2025 financial results. The company reported a significant net loss and provided lower-than-expected revenue guidance for the fourth quarter, disappointing investors.

Donnelley Financial Solutions announced a net loss of $40.9 million, or $1.49 per diluted share, for the third quarter, compared to net earnings of $8.7 million, or $0.29 per diluted share, in the same period last year. The substantial loss was primarily attributed to a non-cash charge of $82.8 million and a $12.5 million cash contribution related to the termination and settlement of its primary defined benefit plan.

Adding to investor concerns, the company reported Q3 net sales of $175.3 million, representing a 2.3% decrease from $179.5 million in the third quarter of 2024. While this figure beat analysts' expectations of $169.7 million, the year-over-year decline raised worries about the company's growth trajectory. Furthermore, Donnelley Financial Solutions provided Q4 revenue guidance of $150 million to $160 million, falling short of the $165.4 million expected by analysts, which likely contributed to the negative market reaction.
