Shares of Louisiana-Pacific (LPX), a leading manufacturer of building products, plunged 5.56% in pre-market trading on Wednesday following the release of its third-quarter earnings report. The company's financial results fell short of analysts' expectations, prompting a negative reaction from investors.

Louisiana-Pacific reported adjusted earnings per share of $0.36 for the third quarter, missing the consensus estimate of $0.42 by 14.29%. This represents a significant decline of 70.49% compared to the same period last year when the company posted earnings of $1.22 per share. Revenue for the quarter came in at $663 million, slightly below the analyst forecast of $664.994 million and down 8.17% year-over-year from $722 million.

Despite the overall disappointing results, there were some positive aspects to the report. The company's adjusted EBITDA for Q3 was $82 million, surpassing the estimate of $80.4 million. Additionally, Louisiana-Pacific reaffirmed its full-year adjusted EBITDA guidance for its Siding segment, projecting net sales growth of $1.68 billion. However, the market's focus on the earnings miss and revenue decline appears to be driving the stock's sharp pre-market drop, as investors reassess the company's near-term growth prospects in light of the challenging economic environment for the building products industry.
