Outlook

LP is providing financial guidance for the fourth quarter of 2025 and full year 2025 as set forth in the table below. Guidance is based on current plans and expectations and is subject to a number of known and unknown uncertainties and risks, including those set forth below under “Forward-Looking Statements.”

Third Quarter 2025 Highlights

Net sales for the third quarter of 2025 decreased by $59 million to $663 million compared to the prior-year period. Siding revenue increased by $22 million (or 5%), primarily due to 5% higher selling prices. OSB revenue decreased by $74 million, driven by a decline in prices.

Net income for the third quarter of 2025 decreased year over year by $82 million to $9 million ($0.13 per diluted share). The decline primarily reflects a $71 million decrease in Adjusted EBITDA, along with asset impairments of $13 million and an $8 million increase in stock compensation, partially offset by a $14 million reduction in tax provision. The year-over-year decrease in Adjusted EBITDA for the third quarter includes a $55 million impact from lower OSB prices, $5 million effect from lower OSB volumes, $12 million in selling, general and administrative expenses (SG&A), and $2 million in tariff expenses. These decreases were partially offset by an $18 million benefit from higher Siding selling prices.

First Nine Months of 2025 Highlights

Net sales for the first nine months of 2025 decreased year over year by $119 million to $2.1 billion. Siding revenue increased by $108 million (or 9%), due to 6% higher volumes and 3% higher selling prices. OSB revenue decreased by $221 million, driven by lower prices.

Net income for the first nine months of 2025 decreased year over year by $204 million to $154 million ($2.20 per diluted share). The decrease primarily reflects a $177 million decrease in Adjusted EBITDA, accompanied by $31 million of impairment charges, a $9 million increase in stock compensation, a $15 million increase in foreign currency loss, and the absence of $14 million in business exit credits recorded in 2024. These impacts were partially offset by a $62 million decrease in the provision for income taxes. The year-over-year decrease in Adjusted EBITDA includes a $199 million impact from lower OSB prices and volumes, $25 million of SG&A, $12 million of inventory valuation charges, and $7 million in tariff expenses primarily related to sales into Canada. These decreases were partially offset by a $70 million benefit from higher Siding sales volumes and selling prices.

Use of Non-GAAP Information

In evaluating our business, we utilize non-GAAP financial measures that fall within the meaning of SEC Regulation G and Regulation S-K Item 10(e), which we believe provide users of the financial information with additional meaningful comparison to prior reported results. Non-GAAP financial measures do not have standardized definitions and are not defined by U.S. GAAP. In this press release, we disclose net income excluding interest expense, provision for income taxes, depreciation and amortization, stock-based compensation expense, loss on impairment attributed to LP, business exit credits and charges, product-line discontinuance charges, other operating credits and charges, net, loss on early debt extinguishment, investment income, pension settlement charges, other non-operating items, income from discontinued operations, net of income taxes, and net income attributed to noncontrolling interest, as Adjusted EBITDA (Adjusted EBITDA), which is a non-GAAP financial measure. We have included Adjusted EBITDA in this report because we view it as an important supplemental measure of our performance and believe that it is frequently used by interested persons in the evaluation of companies that have different financing and capital structures and/or tax rates. We also disclose net income excluding loss on impairment attributed to LP, business exit credits and charges, product-line discontinuance charges, interest expense outside of normal operations, other operating credits and charges, net, loss on early debt extinguishment, gain (loss) on acquisition, pension settlement charges, income from discontinued operations, net of income taxes, and net income attributed to noncontrolling interest, and adjusting for a normalized tax rate, as Adjusted Income (Adjusted Income), which is a non-GAAP financial measure. In addition, we disclose Adjusted Diluted EPS, which is calculated as Adjusted Income divided by diluted shares outstanding (Adjusted Diluted EPS). We believe that Adjusted Diluted EPS and Adjusted Income are useful measures for evaluating our ability to generate earnings and that providing these measures should allow interested persons to more readily compare the earnings for past and future periods. Reconciliations of Adjusted EBITDA, Adjusted Income, and Adjusted Diluted EPS to their most directly comparable U.S. GAAP financial measures, net income and net income per share of common stock - diluted, respectively, are presented below.

Adjusted EBITDA, Adjusted Income, and Adjusted Diluted EPS are not substitutes for the U.S. GAAP measures of net income and net income per share of common stock - diluted or for any other U.S. GAAP measures of operating performance. It should be noted that other companies may present similarly titled measures differently, and therefore, as presented by us, these measures may not be comparable to similarly titled measures reported by other companies. Adjusted EBITDA, Adjusted Income, and Adjusted Diluted EPS have material limitations as performance measures because they exclude items that are actually incurred or experienced in connection with the operation of our business.

KEY PERFORMANCE INDICATORS

The following tables present summary data relating to: (i) housing starts within the United States, (ii) our sales volumes, and (iii) our Overall Equipment Effectiveness (OEE) performance. We consider the following items to be key performance indicators for our business because LP’s management uses these metrics to evaluate our business and trends in our industry, measure our performance, and make strategic decisions. We believe that the key performance indicators presented may provide additional perspective and insights when analyzing our core operating performance. These key performance indicators should not be considered superior to, as a substitute for, or as an alternative to, and should be considered in conjunction with, the financial measures that were prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). These measures may not be comparable to similarly titled performance indicators used by other companies.

We monitor housing starts, which is a leading external indicator of residential construction in the United States that correlates with the demand for many of our products. We believe that this is a useful measure for evaluating our results and that providing this measure should allow interested persons to more readily compare our sales volume for past and future periods to an external indicator of product demand. Other companies may present housing start data differently, and therefore, as presented by us, our housing start data may not be comparable to similarly titled performance indicators reported by other companies.

The following table sets forth housing starts for the three and nine months ended September 30, 2025 and 2024 (in thousands):

We monitor sales volumes for our products in our Siding, OSB, and LPSA segments, which we define as the amount of our products sold within the applicable period measured in million square feet (MMSF) on a standard 3/8" thickness basis. Evaluating sales volume by product type helps us identify and address changes in product demand, broad market factors that may affect our performance, and opportunities for future growth. It should be noted that other companies may present sales volume data differently, and therefore, as presented by us, sales volume data may not be comparable to similarly titled measures reported by other companies. We believe that sales volumes can be a useful measure for evaluating and understanding our business.

The following table sets forth sales volumes for the three and nine months ended September 30, 2025 and 2024 (in MMSF):

We measure OEE of each of our mills to track improvements in the utilization and productivity of our manufacturing assets. OEE is a composite metric that considers asset uptime (adjusted for capital project downtime and similar events), production rates, and finished product quality. We believe that when used in conjunction with other metrics, OEE can be a useful measure for evaluating our ability to generate profits, and that providing this measure should allow interested persons to monitor operational improvements. We use a best-in-class target across all LP sites that allows us to optimize capital investments, focus maintenance and reliability improvements, and improve overall equipment efficiency. It should be noted that other companies may present OEE data differently, and therefore, as presented by us, OEE data may not be comparable to similarly titled measures reported by other companies.

OEE for the three and nine months ended September 30, 2025 and 2024 for each of our segments is listed below:
