Shares of Louisiana-Pacific (LPX) plummeted 5.56% in pre-market trading on Wednesday following the release of its third-quarter 2025 earnings report, which fell short of analyst expectations and showed a significant decline in profits year-over-year.

The building solutions company reported adjusted earnings per share (EPS) of $0.36, missing the analyst consensus estimate of $0.42 by 13.46%. This represents a substantial 70.49% decrease from the $1.22 per share earned in the same period last year. Louisiana-Pacific's quarterly sales came in at $663 million, slightly below the analyst estimate of $664.994 million and down 8.17% from $722 million in the previous year. The company's Q3 siding sales, a key segment, reached $443 million.

Despite the disappointing results, Louisiana-Pacific's adjusted EBITDA of $82 million surpassed the IBES estimate of $80.4 million. The company also reaffirmed its full-year adjusted EBITDA guidance for its siding segment, projecting net sales growth of $1.68 billion for the fiscal year. Additionally, Louisiana-Pacific provided an outlook for Q4 siding net sales growth of $370 million and set its full-year capital expenditure forecast at $315 million. These forward-looking statements, however, did not appear to offset investor concerns about the company's current performance in a challenging market environment.
