Louisiana-Pacific (LPX) Earnings: Q3 2026 Results

The quarter ended September 30, 2026 and Louisiana-Pacific published the results on November 3, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. Louisiana-Pacific reports EPS two ways: GAAP, under the accounting rules every US filer follows, and Adjusted Diluted EPS, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

• In Q1 2026 LP changed its Adjusted Income definition to exclude foreign currency gains and losses and recast prior periods. The year-ago Adjusted Diluted EPS of $0.37 is on that basis; LP says the change added $0.01 per share to Q3 2025.
• OSB segment sales are split in the 10-Q into Structural Solutions, Commodity and a small Other line ($2 million in Q3 2026), so the two indented rows do not add up to the OSB total.

How Louisiana-Pacific splits revenue in its own release, under its own labels, for Q3 2026 against Q3 2025. Indented lines are parts of the line above them.

• Louisiana-Pacific's Siding revenue was $473 million in Q3 2026, up 7% from $443 million in Q3 2025, 68% of total revenue.
• Louisiana-Pacific's OSB revenue was $180 million in Q3 2026, up 1% from $179 million in Q3 2025, 26% of total revenue.
• Louisiana-Pacific's Other revenue was $38.0 million in Q3 2026, down 7% from $41.0 million in Q3 2025, 5% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

From the earnings release

In its Q3 2026 release, Louisiana-Pacific said:

“Siding Net Sales Year-Over-Year Growth $390-400 million (~3% growth)”

“In calculating fourth quarter and full-year OSB Adjusted EBITDA, LP assumes that OSB prices published by Random Lengths remain unchanged from those published on October 30, 2026 (this is an assumption for modeling purposes and not a price forecast).”

“For purposes of calculating the fourth quarter and full year 2026 consolidated Adjusted EBITDA, LP assumes that other operations will contribute approximately $(15) million and $(50) million in the fourth quarter and full-year, respectively.”

“LP expects to spend approximately $140 million on strategic growth projects and $160 million on sustaining maintenance projects in full-year 2026.”

• Q3 2026 (this page), reported Nov 3, 2026

Louisiana-Pacific (LP Building Solutions) had net sales of $691 million in Q3 2026, against $663 million a year earlier. Siding, which LP sells as SmartSide Trim & Siding, ExpertFinish, BuilderSeries and Outdoor Building Solutions, brought in $473 million, a record for the segment. OSB structural panels added $180 million and Other, mainly the South American business, $38 million. (LP Q3 2026 release, Nov 3, 2026)

Siding net sales rose $30 million, or 7%, on both price and volume: average net selling price was up 5% and unit shipments up 2%, to 477 million square feet from 468 million. Over the first nine months Siding sales were still down 2%, at $1,274 million, because unit shipments fell 9% while prices rose 7%. (LP Q3 2026 release, Nov 3, 2026)

LP's OSB sales were flat at $180 million, but the mix shifted. Commodity OSB volume rose 25% while its price fell 6%, and Structural Solutions volume fell 10% at a flat price. In the 10-Q, Structural Solutions sales were $94 million, down from $105 million, and commodity OSB sales $83 million, up from $71 million. During the quarter LP recorded $5 million of severance and other charges for the curtailment of its OSB mill in Jasper, Texas. (LP Q3 2026 release, Nov 3, 2026; Louisiana-Pacific Form 10-Q, Q3 2026, Nov 3, 2026)

LP sells through wholesale distributors, professional dealers and home centers. Its top ten customers accounted for about 47% of net sales in 2025, and no single customer exceeded 10%. U.S. single-family housing starts, which LP tracks as a demand indicator, were 232 thousand in Q3 2026 against 235 thousand a year earlier. (Louisiana-Pacific Form 10-K, 2025, Feb 17, 2026; LP Q3 2026 release, Nov 3, 2026)

Louisiana-Pacific earned $0.32 per diluted share on a GAAP basis in Q3 2026 and $0.39 on its Adjusted Diluted EPS measure. The adjusted figure adds back $9 million of other operating credits and charges, made up mainly of $6 million of reorganization charges and a $3 million loss on asset disposal, removes a $4 million foreign currency gain, and applies a normalized 25% tax rate. (LP Q3 2026 release, Nov 3, 2026; Louisiana-Pacific Form 10-Q, Q3 2026, Nov 3, 2026)

The GAAP rise from $0.13 a year earlier is largely about the comparison quarter: Q3 2025 carried a $13 million loss on impairment, and Q3 2026 had none. Selling, general and administrative expenses also fell to $76 million from $95 million, and stock-based compensation was $6 million against $12 million. (LP Q3 2026 release, Nov 3, 2026)

LP's diluted share count was 70 million in both quarters. It bought back no stock in Q3 2026 or in the first nine months of 2026, after spending $61 million on repurchases in the first nine months of 2025, and paid $21 million in dividends in the quarter. The estimated annual effective tax rate was 26%, excluding discrete items. (LP Q3 2026 release, Nov 3, 2026; Louisiana-Pacific Form 10-Q, Q3 2026, Nov 3, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

Louisiana-Pacific publishes a numeric outlook in its release. For Q4 2026 it expects Siding net sales of $390-400 million (about 3% growth), Siding Adjusted EBITDA of $80-90 million, OSB Adjusted EBITDA of a loss of $35 million and consolidated Adjusted EBITDA of $30-40 million. For full-year 2026 it expects consolidated Adjusted EBITDA of $270-280 million and capital expenditures of about $300 million. (LP Q3 2026 release, Nov 3, 2026)

The OSB figures assume prices published by Random Lengths stay where they were on October 30, 2026, which LP describes as a modeling assumption and not a price forecast. (LP Q3 2026 release, Nov 3, 2026)

A consensus figure is the average of the models published by the analysts who cover Louisiana-Pacific, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones Louisiana-Pacific's own release and filings put weight on for Q3 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning LPX is on is LPX a buy or a sell?, what analysts expect next is on the LPX forecast, and what the company does is on the Louisiana-Pacific (LPX) stock page.

Every number on this page can be traced to a document Louisiana-Pacific published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
