Douglas F. Bauer, Chief Executive Officer stated, “2012 was a highly productive year of growth for TRI Pointe Homes that was highlighted by our strong fourth quarter operating results reflecting improving housing conditions and market acceptance of our well located communities in Northern and Southern California. Having established our Company less than four years ago to capitalize on the unique market opportunities of the housing recovery in California, we are quite pleased with our progress. We have expanded our business in existing markets in California as well as our entry into the Colorado market in October 2012. We are just beginning to harvest the benefits from our rapid land acquisitions and homebuilding activities.”

Mr. Bauer continued, “Our ability to execute and deliver a broad range of new home products to a wide array of homebuyers in high growth markets helped us to realize our most successful year since the inception of the Company. We remain committed to maintaining a prudent amount of leverage and staying focused on our bottom line growth. We continue to be disciplined and highly selective in our approach to building TRI Pointe Homes and to create value for both our shareholders and customers in the coming years.

As a next generation regional homebuilder, unburdened by underperforming assets or legacy issues, our team has been able to leverage our strong local market relationships and established reputations to source acquisitions and obtain land entitlements to position the Company for continued growth in 2015 and beyond.”

Fourth quarter 2012 operating results

New home orders increased, quarter over quarter, to 75 homes for the 2012 fourth quarter, the highest amount of quarterly orders since the Company began acquiring land in 2010. The Company’s overall absorption rate for the three months ended December 31, 2012 per average selling community was 10.7 orders (3.6 monthly), compared to 3.2 orders (1.1 monthly) during the same period in 2011, and a slight increase from 10.6 orders (3.5 monthly) for the 2012 third quarter. The improved order trends for both the 2012 fourth quarter and full year resulted in an increase in the number of homes in backlog to 68, representing $33.3 million in estimated home sales revenue. Supporting this increase was a rise in the average sales price of homes in backlog of $69,000, or 16%, to $490,000 as of December 31, 2012.

For the 2012 fourth quarter, net income was $6.4 million compared to a net loss of $(1.4) million for the fourth quarter 2011, primarily driven by a $10.6 million increase in homebuilding gross margin due to higher home sales revenue and increased homebuilding gross margin percentages. These improvements were partially offset by an increase in SG&A expense for the 2012 fourth quarter to $4.9 million (8.9% of home sales revenue) compared to $2.0 million (47.1% of home sales revenue) for 2011. The increase was attributable to a $1.8 million increase in sales and marketing expenses related to the growth in the number of active selling communities and the number of homes delivered and a $1.1 million increase in general and administrative expenses as the Company continues to invest in its infrastructure to support future growth.

For the 2012 fourth quarter, total revenue was $56.0 million compared to $4.4 million for the same period in 2011. Home sales revenue increased $51.0 million to $55.2 million for the 2012 fourth quarter, as compared to $4.2 million for the same period in 2011, primarily attributable to a significant increase in new homes delivered to 89 and a growth in the Company’s average sales price of homes delivered to $620,000. The increase in the average sales price of homes delivered was primarily

Page 2

attributable to a change in product mix from the deliveries at two new communities in Northern California in the 2012 period. Furthermore, the growth in new home deliveries was due to an increase in the average number of selling communities to seven for the 2012 fourth quarter as compared to 2.5 for the same period in 2011.

The Company’s homebuilding gross margin percentage for the 2012 fourth quarter increased to 20.2% compared to 13.6% for the same period in 2011 and 11.8% in the 2012 third quarter. This increase was primarily due to the delivery unit mix from new projects which achieved higher homebuilding gross margins in the 2012 period. Excluding interest in cost of home sales, adjusted homebuilding gross margin percentage was 21.4%* for the 2012 fourth quarter versus 15.7%* for the same period in 2011.

For the year ended December 31, 2012, net income was $2.5 million compared to a net loss of $(4.6) million in 2011, primarily driven by a $12.3 million increase in homebuilding gross margin due to an increase in home sales revenue of $77.5 million and a higher homebuilding gross margin percentage of 17.8%. These improvements were partially offset by an increase in SG&A expense to $11.4 million (14.7% of home sales revenue).

The Company purchased $68.2 million of land (312 lots) during the 2012 fourth quarter, of which 196 are located in Southern California, 59 in Northern California and 57 in Colorado. The Company purchased $103.3 million of land (511 lots) during the year ended December 31, 2012 of which 332 are located in Southern California, 122 in Northern California and 57 in Colorado. As of December 31, 2012, the Company owned or controlled 1,550 lots, of which 775 are owned and actively selling or under development and 775 are controlled under land option contracts, purchase contracts, or non-binding letters of intent. Of the 1,550 lots owned and controlled, 777 are in Southern California, 520 in Northern California and 253 in Colorado.

Subsequent Events

The Company acquired 301 lots valued at $38.4 million so far in the first quarter, all in Southern California, of which 115 were included in the Company’s lots owned and controlled as of December 31, 2012 and 186 were contracted and closed in the first quarter. Furthermore, an additional 410 lots were contracted in Northern California during the first quarter, bringing the Company’s total lots owned and controlled to over 2,100.

Thomas J. Mitchell, President and Chief Operating Officer of TRI Pointe Homes, noted, “We continue to build on the positive momentum that emerged during last year and expect to continue to execute on our growth strategy in 2013. Since the start of the this year, TRI Pointe Homes has experienced strong demand, increased pricing and reduced incentives in all of our active selling communities during the first quarter and as a result, expect to report our best quarter for new home orders since the inception of the Company. Due to this strong demand, we wrote our final orders and sold out of three of our active selling communities during the first quarter.”

2013 Outlook

In 2013, the Company expects to open nine new selling communities, six in Southern California, two in Northern California and one in Colorado. Based on strong demand to date in 2013, the Company expects to end the first quarter with six active selling communities, including the opening of one new community in Southern California and one in Northern California. In the first quarter, the Company expects to deliver approximately 65% of its 68 units in backlog as of December 31, 2012. The Company’s backlog at the end of the first quarter 2013 is expected to be in excess of 130 homes.

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

In this earnings release, we utilize certain financial measures that are non-GAAP financial measures as defined by the Securities and Exchange Commission. We present these measures because we believe they and similar measures are useful to management and investors in evaluating the company’s operating performance and financing structure. We also believe these measures facilitate the comparison of our operating performance and financing structure with other companies in our industry. Because these measures are not calculated in accordance with Generally Accepted Accounting Principles (“GAAP”), they may not be comparable to other similarly titled measures of other companies and should not be considered in isolation or as a substitute for, or superior to, financial measures prepared in accordance with GAAP.

The following table reconciles homebuilding gross margin percentage, as reported and prepared in accordance with GAAP, to the non-GAAP measure adjusted homebuilding gross margin percentage. We believe this information is meaningful as it isolates the impact that leverage has on homebuilding gross margin and permits investors to make better comparisons with our competitors, who adjust gross margins in a similar fashion.

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES (continued)

The following table reconciles the Company’s ratio of debt-to-capital to the ratio of net debt-to-capital. We believe that the ratio of net debt-to-capital is a relevant financial measure for management and investors to understand the leverage employed in our operations and as an indicator of the Company’s ability to obtain financing.

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES (continued)

The following table calculates the non-GAAP measures of EBITDA and reconciles those amounts to net income (loss), as reported and prepared in accordance with GAAP. EBITDA means net income (loss) before (a) interest expense, (b) income taxes, (c) depreciation and amortization, (d) expensing of previously capitalized interest included in costs of home sales and (e) amortization of equity based incentive units. Other companies may calculate EBITDA (or similarly titled measures) differently. We believe EBITDA information is useful as one measure of the Company’s ability to service debt and obtain financing.

The following table reconciles net cash used in operating activities, as reported and prepared in accordance with GAAP, to EBITDA:
