INSTALLED BUILDING PRODUCTS REPORTS RECORD REVENUE FOR THIRD QUARTER 2018 AND EXPANDS STOCK REPURCHASE PROGRAM BY $100.0 MILLION

Columbus, Ohio, November 1, 2018. Installed Building Products, Inc. (the “Company” or “IBP”) (NYSE:IBP), an industry-leading installer of insulation and complementary building products, announced today results for the third quarter ended September 30, 2018.

Third Quarter 2018 Highlights

Recent Developments

“IBP achieved record revenue in the 2018 third quarter, which was driven by our presence in many of the country’s strongest housing markets. Third quarter revenue growth also benefitted from the contribution of our recent acquisitions, strong revenue performance at Alpha, and price/mix growth,” stated Jeff Edwards, Chairman and Chief Executive Officer. “We reported strong year-over-year earnings growth in the quarter, even though profitability was impacted by material inflation of approximately $4.5 million as manufacturers continue to announce price increases. We are proactively working with customers and suppliers to mitigate these cost impacts, and believe it may take a few quarters for us to fully address the current inflationary material price environment.”

“Our proven acquisition strategy is focused on geographic, product, and end market expansion and I am encouraged by the performance of our recent acquisitions. IBP’s pipeline remains strong and we continue to pursue accretive acquisitions that fit our criteria. Given IBP’s current valuation and the strength of our balance sheet, we are pleased with the Board’s decision to approve a $100.0 million expansion of our stock repurchase program, which demonstrates our commitment to creating shareholder value and our focused approach on maximizing returns on capital.”

Mr. Edwards concluded, “2018 is shaping up to be a record year. We believe we have the leadership team, business plan, and financial model to create significant long-term value for our shareholders, employees, and customers.”

Third Quarter 2018 Results Overview

For the third quarter of 2018, net revenue was $349.0 million, an increase of 18.2% from $295.2 million in the third quarter of 2017. On a same branch basis, net revenue improved 12.2% from the prior year quarter. Residential same branch sales growth was 11.3% in the quarter, with more than half of the increase attributable to growth in the number of completed jobs and the remainder through price gains and more favorable customer and product mix. Same branch single-family sales grew 12.9% during the third quarter, compared to growth in U.S. single-family housing completions of 9.6%, while our large commercial construction end market had organic growth of 15.8%.

Gross profit improved 13.7% to $97.3 million from $85.6 million in the prior year quarter. Adjusted gross profit* as a percent of total revenue was 27.9% which adjusts for the Company’s share-based compensation expense and branch start-up costs, compared to 29.2% for the same period last year, attributable to the impacts of material inflation.

Selling and administrative expense, as a percentage of net revenue, was 18.8% compared to 19.1% in the prior year quarter. Adjusted selling and administrative expense*, as a percentage of net revenue, improved 60 basis points to 17.7% from 18.3%. Higher net revenue in the 2018 third quarter more than offset the higher costs needed to support the Company’s growth.

Net income was $15.6 million, or $0.50 per diluted share, compared to $12.0 million, or $0.38 per diluted share in the prior year quarter. Adjusted net income* was $22.4 million, or $0.72 per diluted share, compared to $18.3 million, or $0.57 per diluted share in the prior year quarter. Adjusted net income adjusts for the impact of non-core items in both periods and includes an addback for non-cash amortization expense related to acquisitions.

Adjusted EBITDA* was $43.8 million, an 11.2% increase from $39.3 million in the prior year quarter, largely due to higher sales and improved selling and administrative leverage. Adjusted EBITDA, as a percentage of net revenue, was 12.5%, compared to 13.3% in the prior year quarter, attributable to the impacts of material inflation.

Stock Repurchase Program

IBP’s Board of Directors has approved an expansion of our stock repurchase program, effective as of November 5, 2018, pursuant to which the Company may repurchase up to an additional $100.0 million of its outstanding common stock. The program will remain in effect until February 28, 2020, unless extended by the Board of Directors. The Board previously approved a stock repurchase program, effective as of March 2, 2018, for up to $50.0 million of the Company’s outstanding common stock and there is currently $7.2 million of remaining availability for additional repurchases.

Under the repurchase program, the Company may purchase shares of its common stock through open market transactions, accelerated share repurchase transactions, privately negotiated transactions, block purchases or otherwise in accordance with applicable federal securities laws, including Rule 10b-18 of the Securities Exchange Act of 1934, as amended and pursuant to any trading plan that may be adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended. The timing and amount of any repurchases under this program will be determined by the Company’s management at its discretion

based on a variety of factors, including the market price of our common stock, corporate considerations, general market and economic conditions, and legal requirements.

*Use of Non-GAAP Financial Measures

In addition to the financial measures prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), this press release contains the non-GAAP financial measures of Adjusted EBITDA, Adjusted EBITDA margin (i.e., Adjusted EBITDA divided by net revenue), Adjusted Net Income, Adjusted Net Income per diluted share, Adjusted Gross Profit and Adjusted Selling and Administrative expense. The reasons for the use of these measures, reconciliations of Adjusted EBITDA, Adjusted Net Income, Adjusted Net Income per diluted share, Adjusted Gross Profit, and Adjusted Selling and Administrative expense to the most directly comparable GAAP measures and other information relating to these measures are included below following the unaudited condensed consolidated financial statements. Non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as a substitute for IBP’s financial results prepared in accordance with GAAP.

Non-GAAP Financial Measures

Reconciliation of Non-GAAP Financial Measures

Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Net Income, Adjusted Gross Profit and Adjusted Selling and Administrative Expense measure performance by adjusting EBITDA, GAAP net income, 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.
