PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS – BASIS OF PRESENTATION

(unaudited)

On January 5, 2017, Installed Building Products, Inc. (“IBP”), a Delaware corporation formed on October 28, 2011, and its wholly-owned subsidiaries and majority-owned subsidiary (collectively referred to as the “Company” and “we”, “us” and “our”), consummated our previously announced acquisition of all of the outstanding shares of Trilok Industries, Inc. (“Trilok”), Alpha Insulation & Waterproofing, Inc. (“Alpha”) and Alpha Insulation & Waterproofing Company (“Alpha Company” and together with Trilok and Alpha, the “Alpha Companies”).

The unaudited pro forma condensed combined balance sheet as of September 30, 2016 is based on our historical consolidated financial statements as well as the historical combined financial statements of the Alpha Companies and is presented as if the acquisition of the Alpha Companies and the payment of the purchase price therefor as described in item 2.01 of this Form 8-K/A occurred in its entirety on September 30, 2016. The unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2016 and for the year ended December 31, 2015 are based on our historical consolidated financial statements as well as the historical combined financial statements of the Alpha Companies and is presented as if the acquisition of the Alpha Companies and the payment of the purchase price therefor by the Company occurred on January 1, 2015. The unaudited pro forma condensed combined financial statements should be read in conjunction with the historical consolidated financial statements and notes related thereto appearing in our Form 10-K for the year ended December 31, 2015 and the historical consolidated financial statements and notes related thereto appearing in our Form 10-Q for the nine months ended September 30, 2016 as well as the historical combined financial statements of the Alpha Companies for each respective period appearing in exhibits 99.1 and 99.2 to this Form 8-K/A.

Preparation of the pro forma information was based on assumptions considered appropriate by management. The pro forma financial information is unaudited and is not necessarily indicative of the results which would have occurred if the transactions described above had been consummated on September 30, 2016 for the pro forma condensed combined balance sheet and on January 1, 2015 for the pro forma condensed combined statements of operations, nor does it purport to represent the future financial position and the results of operations for future periods.

In management’s opinion, all adjustments necessary to reflect the effects of the transactions listed above have been made. However, the unaudited pro forma condensed combined financial statements are based upon currently available information and preliminary estimates and assumptions that management believes are reasonable as of the date hereof. Any of these preliminary estimates and assumptions may change and the estimates and assumptions may not be representative of facts existing at the time of the acquisition. The unaudited pro forma condensed combined financial statements do not reflect the costs of any integration activities nor any cost savings from operating efficiencies, synergies or other restructuring, or associated costs to achieve such savings that may result from the acquisition.

The unaudited pro forma condensed combined financial information conforms the accounting policies of the Alpha Companies to ours to the extent applicable to our existing accounting policies. All information is prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). Certain historical amounts of the Alpha Companies have been reclassified to conform to our presentation. See Note 1 – Basis of Presentation for further information. Based on our preliminary review of the summary of significant accounting policies disclosed in the historical financial statements of the Alpha Companies, no material differences exist to our significant policies. However, a further detailed review is currently being performed. As a result of that review, we may identify differences between the accounting policies of the two companies that, when conformed, may have a material impact on the consolidated financial statements.

NOTE 1 – BASIS OF PRESENTATION

The unaudited pro forma condensed combined financial statements present the pro forma financial position and statement of operations of the combined company based upon historical financial information after giving effect to the acquisition and adjustments described in these footnotes.

The unaudited pro forma condensed combined financial information is based on our historical consolidated financial statements as well as the historical combined financial statements of the Alpha Companies using the acquisition accounting method in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations, and include all adjustments that are directly attributable to the transactions, are factually supportable and, with respect to the unaudited pro forma condensed combined statements of operations, are expected to have a continuing impact on the combined results. In accordance with ASC 805, we allocate the purchase price of the acquisition to the tangible assets, liabilities, and identifiable intangible assets acquired based on their estimated fair values. The excess of the purchase price over those fair values is recorded as goodwill. During the measurement period, as additional information becomes available about facts and circumstances that existed as of acquisition date, we may further revise our preliminary valuation of assets acquired and liabilities assumed with the corresponding offset to goodwill. After the measurement period, which could be up to one year after the initial transaction date, we may record subsequent adjustments to our statement of operations.

The allocation of the purchase price is preliminary and based on valuations derived from estimated fair value assessments and assumptions used by management. The estimated fair values of the assets acquired and liabilities assumed are considered preliminary and are based on the information that was available as of the date of the acquisition. We believe that the information provides a reasonable basis for estimating the fair value of assets acquired and liabilities assumed, however, the preliminary measurements of fair value are subject to change.

The unaudited pro forma condensed combined financial information does not give effect to the potential impact of current financial conditions, regulatory matters, operating efficiencies or other savings or expenses that may be associated with the acquisition. The unaudited pro forma condensed combined financial information also does not include any future integration costs. The unaudited pro forma condensed combined financial information has been prepared by management for illustrative purposes only in accordance with Article 11 of SEC Regulation S-X and are not necessarily indicative of the combined financial position or results of operations in future periods or the results that actually would have been realized had Installed Building Products, Inc. and the Alpha Companies been operating as a combined company during the specified periods presented.

All financial statements are prepared in accordance with accounting principles generally accepted in the United States. Certain amounts in the historical combined financial statements of the Alpha Companies have been reclassified to conform to our financial statement presentation, including gain (loss) on disposal of equipment which has been presented in cost of sales within the unaudited pro forma condensed combined statements of operations. We will continue to assess the accounting policies of the Alpha Companies for adjustments in addition to those reflected in the unaudited pro forma condensed combined financial information that may be required to conform the accounting policies of Installed Building Products, Inc. and the Alpha Companies.

NOTE 2 – PRELIMINARY PURCHASE PRICE ALLOCATION

On January 5, 2017, we consummated our previously announced acquisition of all of the outstanding shares of the Alpha Companies for total consideration of $116.7 million consisting of approximately $81.9 million in cash, $10.9 million by issuing 282,577 shares of our common stock, as adjusted for a marketability adjustment, and seller obligations totaling $1.9 million. The purchase price also includes customary adjustments for cash and net working capital, earnout consideration based on the change in EBITDA of the Alpha Companies from 2015, and a customary holdback. We paid approximately $21.7 million to satisfy these items on March 7, 2017. Lastly, we assumed $0.3 million in debt of the Alpha Companies.

Under the purchase method of accounting, we allocated the total purchase price of $116.7 million to the net tangible and intangible assets acquired and liabilities assumed based upon their respective estimated fair values as of the

initial transaction date. We incurred $0.5 million of transaction costs and the Alpha Companies incurred an additional $0.2 million of transaction costs during the three months ended December 31, 2016, which have been included as an adjustment to the unaudited pro forma condensed combined balance sheet. See Note 3 – Pro Forma Adjustments for further information. The following summarizes the preliminary purchase price allocation as of the acquisition date (in thousands):

Identifiable intangible assets. The preliminary fair values of intangible assets were determined based on the provisions of ASC 805, which defines fair value in accordance with ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”). ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The intangible assets were determined using a combination of the income and market approaches where we used market data to guide many of the assumptions in the discounted cash flows model. Additionally, valuation of the fair value of backlog is determined by carving out a portion of the customer relationship intangible asset based on total amount of backlog, length of time to recover cash flows, and the same discounting method as the customer relationships.

We have preliminarily allocated $57.1 million to identifiable intangible assets. The preliminary valuation of the identifiable intangible assets acquired was based on management’s estimates, currently available information and reasonable and supportable assumptions. The allocation was based on the fair value of these assets. The amortization expense related to the preliminary fair value of the intangible assets is reflected as a pro forma adjustment to the unaudited pro forma condensed combined financial statements. The identifiable intangible assets will be amortized over the useful lives of each individual asset identified on a straight-line basis as follows (dollars in thousands):

Goodwill. Goodwill represents the excess of the purchase price over the fair value of the underlying net assets acquired, net of deferred taxes. The goodwill to be recognized in conjunction with the acquisition is attributable to expected improvement in the business of the acquired company. In accordance with ASC Topic 350, Intangibles—Goodwill and Other, goodwill will not be amortized, but instead tested for impairment at least annually and

whenever events or circumstances have occurred that may indicate a possible impairment. In the event management determines that the value of goodwill has become impaired, we will incur a noncash charge for the amount of the impairment during the period in which the determination is made.

The acquisition accounting for the acquisition is preliminary and subject to completion upon obtaining the necessary remaining information, including (1) the identification and valuation of assets acquired and liabilities assumed, including intangible assets and related goodwill, (2) the finalization of the opening balance sheet, including certain accruals and prepaid expenses, and (3) the related tax impacts of the acquisition. We have preliminarily valued the acquired assets and liabilities based on their estimated fair value. These estimates are subject to change as additional information becomes available. Any adjustments to the preliminary fair values will be made as such information becomes available and made within the customary measurement period.
