Sylvamo's stock price plummeted 5.82% during intraday trading on Thursday, following the release of the company's fourth-quarter 2025 earnings results.

The paper products manufacturer reported adjusted operating earnings of $1.08 per share for Q4 2025, representing a 44.9% decrease from the $1.96 per share reported in the same period last year. Net sales also declined to $890 million, down 8.25% from $970 million a year earlier. Additionally, net income dropped 59% to $33 million compared to the prior year period.

While the company's earnings and sales exceeded analyst consensus estimates, the substantial year-over-year declines across key financial metrics appear to have concerned investors, leading to the significant stock price drop during Thursday's trading session.
