Unaudited Pro Forma Condensed Combined Financial Information of TRI Pointe Homes, Inc. and Weyerhaeuser Real Estate Company

The following presents unaudited pro forma condensed combined statements of operations based upon the combined historical financial statements of WRECO and TRI Pointe, after giving effect to the Transactions between WRECO and TRI Pointe and adjustments described in the accompanying notes. Capitalized terms used herein are defined below under the caption “Helpful Definitions.”

The Transactions are accounted for as a reverse acquisition under the acquisition method of accounting, which requires determination of the accounting acquirer. The accounting guidance for business combinations, Accounting Standards Codification 805, Business Combinations (“ASC 805”), provides that in identifying the acquiring entity in a combination effected through an exchange of equity interests, all pertinent facts and circumstances must be considered, including the following:

Based on the foregoing analysis, WRECO is considered the accounting acquirer in the Transactions. The historical consolidated financial statements for all periods prior to the consummation of the Transactions will only reflect the historical consolidated financial statements of WRECO. Purchase accounting will apply to the assets and liabilities of TRI Pointe.

The unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2014 reflect the Transactions as if they were consummated on January 1, 2013.

The unaudited pro forma condensed combined financial information should be read in conjunction with (1) the unaudited and audited consolidated historical financial statements of TRI Pointe and the notes thereto, which are included in TRI Pointe’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2014 (filed with the SEC on November 13, 2014) and its Annual Report on Form 10-K for the year ended December 31, 2013, as amended, (filed with the SEC on February 27, 2014); (2) the unaudited and audited consolidated historical financial statements of WRECO and the notes thereto, which are included in TRI Pointe’s Registration Statement on Form S-4 (Registration No. 333-193248) (declared effective by the SEC on May 22, 2014); and (3) the disclosures contained in each company’s Management’s Discussion and Analysis of Financial Condition and Results of Operations. Additional information about the basis of presentation of this information is provided in Note 1. Basis of Presentation below.

The unaudited pro forma condensed combined financial information was prepared in accordance with Article 11 of Regulation S-X. The unaudited pro forma adjustments reflecting the consummation of the Transactions have been prepared in accordance with business combination accounting guidance as provided in ASC 805 and reflect the preliminary allocation of the purchase price to the acquired assets and liabilities based upon their estimated fair values, using the assumptions set forth in the notes to the unaudited pro forma condensed combined financial information.

The unaudited pro forma condensed combined financial information is provided for informational purposes only and is not necessarily indicative of the operating results or financial position that would have occurred if the Transactions had been completed as of the dates set forth above, nor is it indicative of the future results or financial position of the combined company. In connection with the pro forma financial information, TRI Pointe allocated the purchase price using its best estimates of fair value of its assets and liabilities. These estimates are based on the most recently available information. The

allocation is dependent upon certain valuation and other analyses that are not yet final. Accordingly, the pro forma acquisition price allocations are preliminary and subject to further adjustments as additional information becomes available and as additional analyses are performed. There can be no assurance that the final valuations will not result in material changes to these preliminary purchase price allocations.

The unaudited pro forma condensed combined financial information also does not give effect to the potential impact of current financial conditions, any anticipated synergies, operating efficiencies or cost savings that may result from the Transactions or any integration costs. Furthermore, the unaudited pro forma condensed combined statement of operations does not include certain nonrecurring charges and the related tax effects which result directly from the Transactions as described in the notes to the unaudited pro forma condensed combined financial information.

(in thousands, except earnings per share amounts)

The accompanying notes are an integral part of, and should be read together with, this unaudited pro forma condensed combined financial information.

Notes to Unaudited Pro Forma Condensed Combined Financial Information

1. Basis of Presentation

The historical consolidated financial information has been adjusted to give pro forma effect to events that are (i) directly attributable to the Transactions, (ii) factually supportable and (iii) expected to have a continuing impact on the combined results. The pro forma adjustments are preliminary and based on estimates of the fair value and useful lives of the assets acquired and liabilities assumed and have been prepared to illustrate the estimated effect of the Transactions and certain other adjustments.

The historical results are derived from TRI Pointe’s unaudited consolidated statement of operations for the nine months ended September 30, 2014 as reported on Form 10-Q filed with the SEC on November 13, 2014. These results are comprised of WRECO’s historical results as the accounting acquirer and TRI Pointe results from July 7, 2014 (“Closing Date”) forward. TRI Pointe’s standalone results are derived from TRI Pointe’s unaudited consolidated statement of operations from January 1, 2014 through the Closing Date.

The denominator used to calculate pro forma combined basic earnings per common share was the total outstanding shares as of September 30, 2014. The denominator used to calculate pro forma combined diluted earnings per common share was derived from the shares used to calculate basic earnings per common share plus 950,000 shares attributable to the dilutive effect of outstanding equity awards.

Significant Accounting Policies

The accounting policies used in the preparation of this unaudited pro forma condensed combined financial information are those set forth in WRECO’s and TRI Pointe’s audited consolidated financial statements as of December 31, 2013. TRI Pointe’s management has determined that no material adjustments are necessary to conform TRI Pointe’s financial statements to the accounting policies used by WRECO in the preparation of the unaudited pro forma condensed combined financial information. Certain reclassification adjustments have been made in the unaudited pro forma condensed combined financial statements to conform TRI Pointe’s historical basis of presentation to that of WRECO.

Description of Transaction

On November 4, 2013, TRI Pointe and Weyerhaeuser announced that they, along with WRECO and Merger Sub, had entered into the Transaction Agreement, which provides for the combination of TRI Pointe’s business and the Real Estate Business.

On May 22, 2014, Weyerhaeuser commenced an exchange offer in connection with the Transactions, pursuant to which Weyerhaeuser shareholders had the option to exchange all, some or none of their Weyerhaeuser common shares, par value $1.25 per share, for WRECO common shares, par value $0.04 per share. The exchange offer and withdrawal rights expired at 12:00 midnight, New York City time, on July 2, 2014.

On the date of the Distribution, WRECO incurred the New Debt and used the proceeds thereof to make a cash payment to WNR, a subsidiary of Weyerhaeuser. Weyerhaeuser then caused the REB Transfers to occur. Following the REB Transfers, Weyerhaeuser caused WNR to distribute all of the issued and outstanding WRECO common shares to Weyerhaeuser in the WRECO Spin. On July 7, 2014, Merger Sub merged with and into WRECO, with WRECO surviving the Merger and becoming a wholly owned subsidiary of TRI Pointe. In the Merger, each issued and outstanding WRECO common share was converted into the right to receive 1.297 fully paid and non-assessable shares of TRI Pointe common stock. On July 7, 2014, WNR paid TRI Pointe an Adjustment Amount of $31.5 million in cash.

In the Merger, TRI Pointe issued 129,700,000 shares of TRI Pointe common stock, excluding shares to be issued on exercise or vesting of equity awards held by WRECO employees that were assumed by TRI Pointe in connection with the Transactions. Based upon the reported closing sale price of $15.85 per share for TRI Pointe common stock on the NYSE on July 7, 2014, the total value of the shares issued by TRI Pointe and the amount of cash received by WNR, a subsidiary of Weyerhaeuser, in the Transactions, including from the proceeds of the New Debt (which was assumed by TRI Pointe and is guaranteed by TRI Pointe’s material wholly owned subsidiaries, including WRECO and its material wholly owned subsidiaries, subject to certain exceptions) as discussed below but not including any Adjustment Amount, was $2.8 billion.

Upon the consummation of the Transactions, equity awards in Weyerhaeuser common shares held by WRECO employees were converted into 2.1107 equity awards of TRI Pointe common stock. As of July 7, 2014, there were 1,125,589 unvested and 819,885 vested equity awards in Weyerhaeuser common shares held by WRECO employees that were

converted into 726,856 unvested TRI Pointe restricted stock units and 1,648,925 unvested and 1,730,531 vested options exercisable for shares of TRI Pointe common stock. The exercise price of the Weyerhaeuser options ranged from $9.53 to $30.54, and the exercise price of the replacement TRI Pointe options will range from $4.52 to $14.47. The fair value of the Weyerhaeuser equity awards and the replacement equity awards were measured as of July 7, 2014. The excess fair value of the TRI Pointe options, amounting to $4.8 million, will be recognized as additional compensation expense over the term of the unvested equity awards. For purposes of the unaudited pro forma condensed consolidated statement of operations for the nine months ended September 30, 2014, additional compensation expense related to the increase in fair value to the WRECO employee equity awards was $0.9 million, as discussed in explanation (c) of Note 2. Notes to Unaudited Pro Forma Condensed Combined Statements of Operations. Significant assumptions used in the measurement of fair value of the replacement options included expected terms, volatility, annual discount rate and the risk free rate.

After the consummation of the Merger, TRI Pointe owns and operates the Real Estate Business through WRECO, which is a TRI Pointe wholly owned subsidiary, and also continues its pre-Merger businesses. TRI Pointe common stock, including the shares issued in the Merger, is listed on the NYSE under TRI Pointe’s current trading symbol “TPH.”
