Installed Building Products, Inc. (IBP) Earnings: Q3 2026 Results

The quarter ended September 30, 2026 and Installed Building Products published the results on November 5, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. Installed Building Products reports EPS two ways: GAAP, under the accounting rules every US filer follows, and Diluted adjusted net income per share, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

• Installed Building Products reports one segment, Installation. Other covers its Distribution and Manufacturing operating segments, net of inter-segment eliminations of $24.5 million in Q3 2026.
• Installed Building Products does not publish a revenue or earnings outlook in its release.

How Installed Building Products 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.

• Installed Building Products's Installation revenue was $740 million in Q3 2026, up 3% from $721 million in Q3 2025, 92% 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.

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.

Installed Building Products does not publish a revenue or earnings outlook in its release. The one forward figure it gives is acquisitions: it continues to believe it will acquire at least $100 million in revenue in 2026, after about $67 million so far, and it closed a $250 million add-on to its Term Loan B, which it says strengthens its ability to execute its acquisition strategy.

A consensus figure is the average of the models published by the analysts who cover Installed Building Products, 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 Installed Building Products'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 IBP is on is IBP a buy or a sell?, what analysts expect next is on the IBP forecast, and what the company does is on the Installed Building Products, Inc. (IBP) stock page.

Every number on this page can be traced to a document Installed Building Products 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.
