Sylvamo's stock surged 5.18% during intraday trading on Thursday, following the release of its fourth-quarter financial results that exceeded analyst expectations across key metrics.

The paper company reported Q4 revenue of $890 million, beating the consensus estimate of $858.76 million. Adjusted earnings per share came in at $1.08, surpassing the $1.07 forecast, while adjusted EBITDA reached $125 million, above the $121.09 million expectation. The better-than-expected performance was driven by higher volumes in Latin America, which helped offset challenges in other regions.

Looking ahead, Sylvamo expects paper price increases in North America to begin realization in the second quarter and plans $145 million in strategic investments at its Eastover mill in 2026. The company's positive financial results and forward-looking guidance appear to have driven investor optimism during the trading session.
