Why record sales aren't lifting Installed Building Products' profit
Acquisitions supplied most of the third-quarter sales increase. At existing branches, adjusted earnings fell despite a slight recovery in revenue.

Installed Building Products sold more in the third quarter but kept less of each sales dollar. Revenue reached a record $808.4 million, up 3.9% from a year earlier. Net income fell to $59.4 million from $74.4 million.
For the insulation and building-products installer, buying businesses is helping offset a subdued housing market. The problem is that those additions are not making up for the earnings decline at its established branches.
The acquisitions are doing most of the work
Acquired businesses supplied $25.4 million of the $30.2 million revenue increase. Branches owned for more than a year added just $4.8 million.
The gap was larger in profit. Acquisitions added $3.8 million to adjusted EBITDA, a measure of earnings before interest, taxes, depreciation, amortization and specified adjustments. Existing branches earned $15.4 million less on that measure, leaving the group down $11.6 million.
| Measure | 2025 | 2026 |
|---|---|---|
| Revenue | $778.2 | $808.4 |
| Net income | $74.4 | $59.4 |
| Adjusted EBITDA | $139.9 | $128.3 |
| Gross margin | 34.0% | 31.8% |
Commercial work helps, but margins weaken
There was progress beneath the headline. Revenue at existing branches rose 0.6%, following a 0.6% decline in the second quarter. Residential installation sales at those branches were still down 2.6%, but that was a smaller fall than the previous quarter's 6.1%. Commercial sales grew 10.3%.
That commercial work cushions the housing slowdown. It has not prevented a profit squeeze. The installation business's gross margin fell to 35.0% from 36.9%. Distribution and manufacturing margins also weakened. Management cited higher costs, including fuel and aluminum, alongside a shift toward lower-margin sales.
The cash comparison is weaker, too
Research by Ticker Byline shows that third-quarter operating cash flow fell to $74.8 million from $124 million a year earlier, using the nine-month reports less the corresponding first-half reports. Lower earnings and more cash tied up in customer receivables contributed to the decline.
Cash on hand nevertheless increased during the quarter, reaching $415.9 million at September 30. After the quarter, IBP completed a $250 million addition to its term loan, with proceeds for general corporate purposes and transaction fees.
By November, the businesses bought during 2026 represented $67 million of annual revenue, against management's unchanged goal of at least $100 million for the year. Our Installed Building Products company page tracks the completed deals, financial results and borrowing.
More acquisitions can lift sales. For earnings to follow, IBP also needs its existing branches to keep more of the revenue they already generate.
