INSTALLED BUILDING PRODUCTS REPORTS RESULTS FOR FOURTH QUARTER, ACHIEVES RECORD REVENUE FOR FULL YEAR 2013

Columbus, Ohio, March 26, 2014. Installed Building Products, Inc. (the “Company” or “IBP”), an industry-leading installer of insulation products, announced today results for the fourth quarter and full year ended December 31, 2013.

Fourth Quarter 2013 Highlights

Full Year 2013 Highlights

“The significant growth we achieved in our revenue and profits during 2013 as compared to the prior year was the result of the expansion strategy we put in place and the improving demand for our services,” stated Jeff Edwards, Chairman and Chief Executive Officer. “Our 2013 fourth quarter revenue growth of 30.6% reflects the strong demand environment for our installation service offerings, especially in new residential end markets, and the steps we have taken to continue expanding our footprint across the nation. Furthermore, our full year same branch revenue improvement of 29.6% exceeded the 17.7% increase in U.S. housing completions during 2013, which reflects our strategic focus on establishing market-leading positions in the most attractive U.S. housing markets. As we progress through 2014, we are well positioned to continue capitalizing on the new home construction recovery, strengthening our market position and pursuing value-enhancing acquisitions while remaining disciplined with our costs to improve profitability. In the first quarter of 2014, adverse winter weather conditions have slowed sales growth in many of our markets due to delayed construction activity; however, we expect to regain most of any weather-impacted demand during the remainder of the year.”

Gross profit was $31.2 million, an increase of 43.1% from $21.8 million in the prior year quarter. Gross margin improved to 26.2% from 23.9% in the prior year quarter, primarily due to higher net revenue and improved labor efficiencies.

Operating income of $4.5 million increased 55.3% from $2.9 million in the prior year quarter.

Non-GAAP Financial Measures

The reasons for the use of Adjusted EBITDA, a reconciliation of Adjusted EBITDA to the most directly comparable GAAP measure and other information relating to Adjusted EBITDA is included below following the unaudited consolidated financial statements.

Reconciliation of Non-GAAP Financial Measures

Adjusted EBITDA measures performance by adjusting EBITDA for certain income or expense items that are not considered part of our core operations. We believe that the presentation of this measure 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 also believe this 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 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 this 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, net (loss) income in accordance with GAAP 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 (loss) income from continuing operations 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 (used in) 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.

The table below reconciles Adjusted EBITDA to the most directly comparable GAAP financial measure, net (loss) income (loss) for the periods presented therein.
