FIRST QUARTER 2026 RESULTS;

DECLARES REGULAR QUARTERLY CASH DIVIDEND

Columbus, Ohio, May 7, 2026, Installed Building Products, Inc. (the "Company" or "IBP") (NYSE: IBP), an industry-leading installer of insulation and complementary building products, today announced results for the first quarter ended March 31, 2026.

First Quarter 2026 Highlights (Comparisons are to Prior Year Period)

•Net revenue decreased 3.5% to $660.5 million

◦Installation revenue decreased 5.8% to $609.8 million, including sales from IBP's recent acquisitions

◦Other revenue, net of eliminations, which includes IBP’s manufacturing and distribution operations, increased 34.8% to $50.7 million

•Net income decreased to $34.8 million

•Adjusted EBITDA* decreased to $92.1 million

•Net income per diluted share decreased to $1.29

•Adjusted net income* was $48.4 million, or $1.79 per diluted share

•Net cash flow from operations increased 11.1% to $102.3 million

•At March 31, 2026, IBP had $474.3 million in cash and cash equivalents

•Repurchased approximately 91 thousand shares of common stock at a total cost of approximately $25.4 million

•Declared first quarter dividend of $0.39 per share that was paid to shareholders on March 31, 2026

Recent Developments

•IBP’s Board of Directors declared the second quarter regular cash dividend of $0.39 per share, representing more than a 5% increase to the Company's regular dividend in the prior year period

•Effective May 6, 2026, Ryan Ricketts has been appointed Director of Investor Relations and Financial Planning, succeeding Darren Hicks, who will be departing the Company to pursue another opportunity

“We delivered solid top-line results amidst challenging regional weather conditions and a macroeconomic backdrop that has raised uncertainty with respect to U.S. consumer sentiment and new home sales activity. Throughout the quarter, we remained focused on meeting customers' needs through maintaining elevated service quality while emphasizing product diversification and prudent expense management. Our commercial end market continued to show strength, delivering double-digit installation sales growth. Heavy commercial sales growth exceeded 20% and the commercial end market also benefited from light commercial acquisition revenue. While we expect near-term challenges within U.S. residential construction to continue, we remain intentional with our pursuit of growth and capital allocation decisions,” stated Jeff Edwards, Chairman and Chief Executive Officer.

“I also want to thank Darren, who has been a valued member of our team since joining IBP in March 2021,” continued Mr. Edwards. “Ryan, as Director of Financial Planning, has played an integral role in our financial planning and analysis function, and he is a natural fit to lead our investor relations efforts. I look forward to his contributions as we continue to execute on our strategy and engage with the investment community and wish Darren the best in his future endeavors.”

First Quarter 2026 Results Overview

For the first quarter of 2026, net revenue was $660.5 million, a decrease of 3.5% from $684.8 million for the first quarter of 2025. On a consolidated same branch basis, net revenue decreased 5.9% from the prior year quarter. Residential same branch sales within the Company's Installation segment were down 11.2% in the quarter while commercial same branch sales within the Installation segment were up 10.7% from the prior year quarter.

Our price/mix results were flat during the first quarter and job volumes were down 10.0% relative to the same period last year. It is important to note that the results of our heavy commercial end market and the Other segment results are not included in that price/mix and volume disclosure. Including the heavy commercial installation sales, but still excluding the Other segment results, price mix increased 2.9% while job volume was down 9.9% during the 2026 first quarter.

Gross profit decreased 5.1% to $212.3 million in the first quarter of 2026 from $223.7 million in the prior year quarter. As a percent of net revenue, gross profit was 32.1% and adjusted gross profit* was 32.2%, compared to 32.7% in the same period last year. Higher vehicle-related expense as a percent of net revenue served as a notable headwind to our first quarter of 2026 adjusted gross profit margin performance relative to the prior year period. Adjusted gross profit primarily adjusts for the Company’s share-based compensation expense.

Selling and administrative expense, as a percent of total revenue, was 21.8% in the first quarter of 2026 and 21.0% in the prior year period. Adjusted selling and administrative expense*, as a percent of net revenue, was 20.9% compared to 20.1% in the prior year quarter. Adjusted administrative expense as a percent of net revenue was impacted by higher medical and general liability insurance relative to the prior year.

Net income was $34.8 million, or $1.29 per diluted share, compared to $45.4 million, or $1.64 per diluted share in the prior year quarter. Net profit margin for the first quarter was 5.3% compared to 6.6% in the prior year quarter. Adjusted net income* was $48.4 million, or $1.79 per diluted share, compared to $57.6 million, or $2.08 per diluted share in the prior year quarter. Adjusted net profit margin* for the first quarter was 7.3% compared to 8.4% in the prior year quarter. Adjusted net income accounts for the impact of non-core items in both periods, including an addback for non-cash amortization expense related to acquisitions.

EBITDA* in the first quarter of 2026 was $85.4 million, an 11.0% decrease from $96.0 million in the prior year quarter. Adjusted EBITDA* was $92.1 million, a 10.1% decrease from the prior year quarter representing an adjusted EBITDA margin* of 13.9%. In the prior year quarter, adjusted EBITDA* was $102.4 million, representing an adjusted EBITDA margin* of 15.0%.

Reconciliation of Non-GAAP Financial Measures

EBITDA, Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Net Income, Adjusted Gross Profit and Adjusted Selling and Administrative Expense measure performance by adjusting GAAP net income, EBITDA, gross profit and selling and administrative expense, respectively, for certain income or expense items that are not considered part of our core operations. We believe that the presentation of these measures provides useful information to investors regarding our results of operations because it assists both investors and us in analyzing and benchmarking the performance and value of our business.

We believe the Adjusted EBITDA measure is useful to investors and us as a measure of comparative operating performance from period to period as it measures our changes in pricing decisions, cost controls and other factors that impact operating performance, and removes the effect of our capital structure (primarily interest expense), asset base (primarily depreciation and amortization), items outside our control (primarily income taxes) and the volatility related to the timing and extent of other activities such as asset impairments and non-core income and expenses. Accordingly, we believe that this measure is useful for comparing general operating performance from period to period. In addition, we use various EBITDA-based measures in determining the achievement of awards under certain of our incentive compensation programs. Other companies may define Adjusted EBITDA differently and, as a result, our measure may not be directly comparable to measures of other companies. In addition, Adjusted EBITDA may be defined differently for purposes of covenants contained in our revolving credit facility or any future facility.

Although we use the Adjusted EBITDA measure to assess the performance of our business, the use of the measure is limited because it does not include certain material expenses, such as interest and taxes, necessary to operate our business. Adjusted EBITDA should be considered in addition to, and not as a substitute for, GAAP net income as a measure of performance. Our presentation of this measure should not be construed as an indication that our future results will be unaffected by unusual or non-recurring items. This measure has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Because of these limitations, this measure is not intended as an alternative to net income as an indicator of our operating performance, as an alternative to any other measure of performance in conformity with GAAP or as an alternative to cash flow provided by operating activities as a measure of liquidity. You should therefore not place undue reliance on this measure or ratios calculated using this measure.

We also believe the Adjusted Net Income measure is useful to investors and us as a measure of comparative operating performance from period to period as it measures our changes in pricing decisions, cost controls and other factors that impact operating performance, and removes the effect of certain non-core items such as discontinued operations, acquisition related expenses, amortization expense, the tax impact of these certain non-core items, and the volatility related to the timing and extent of other activities such as asset impairments and non-core income and expenses. To make the financial presentation more consistent with other public building products companies, beginning in the fourth quarter 2016 we included an addback for non-cash amortization expense related to acquisitions. Accordingly, we believe that this measure is useful for comparing general operating performance from period to period. Other companies may define Adjusted Net Income differently and, as a result, our measure may not be directly comparable to measures of other companies. In addition, Adjusted Net Income may be defined differently for purposes of covenants contained in our revolving credit facility or any future facility.

(1) Same-branch basis represents period-over-period change in sales for branch locations owned greater than 12 months as of each financial statement date.

(2) Calculated based on period-over-period change in sales of all end markets for our Installation segment,.

(3) Calculated based on period-over-period change in sales in the residential new construction end market for our Installation segment.

(4) Calculated based on period-over-period change in sales in the single-family subset of the residential new construction end market for our Installation segment,

(5) Calculated based on period-over-period change in sales in the multi-family subset of the residential new construction end market for our Installation segment,

(6) Calculated based on period-over-period change in sales in the total commercial end market for our Installation segment, Our commercial end market consists of heavy and light commercial projects.

(7) The heavy commercial end market, a subset of our total commercial end market, comprises projects that are much larger than our average installation job. As such, per-job revenue is much larger than the average job in all other end markets.

(8) Calculated as period-over-period change in the number of completed same-branch jobs within our Installation segment for all markets.

(9) Defined as change in the mix of products sold and related pricing changes and calculated as the change in period-over-period average selling price per same-branch jobs within our Installation segment for all markets we serve, multiplied by total current year jobs. The mix of end customer and product would have an impact on the year-over-year price per job.

(10) Calculated based on period-over-period gross sales change, excluding intercompany transactions, in our Other category

which consists of our Manufacturing and Distribution operating segments.

(11) We revised this calculation to exclude certain intercompany sales. Percentages in all periods presented conform to this

revised method.
