Investment Thesis: After incorporating 1Q08 results, a faster-thanexpected increase in debt, and the additional shares issued in the October 2007 follow-on equity offer into our valuation model, we are lowering our year-end 2008 target price for Urbi from M$55.00 (US$4.85) to M$41.50 (US$3.80) per share. Nevertheless, we are maintaining our Buy rating based on a potential upside of 16% in U.S. dollars from current levels compared with our 6.25% expected Mexican benchmark return. Reasons for Change to Price Target/Estimates: Through April 29, Urbi stock significantly underperformed, having posted a negative 8.3% return compared to a positive 20.1% by Geo and 18.9% by Homex. This performance, in our opinion, is explained by the stock overhang caused by the follow-on equity offer in October 2007, the use of off-balance-sheet debt, and the rapid increase in net debt due to consistently negative free cash flow. These factors created concerns that were not offset by Urbi s being one of the fastest growing and most profitable companies in the housing sector in Mexico. Nevertheless, in the 1Q08 press release and conference call, management stated that they intend to stop the growth of offbalance-sheet debt (factoring), reduce negative free cash flow by improving working capital management, and to increase net debt at a more moderate pace. These intentions, together with the high expected EBITDA growth, are all positives in our opinion and, if achieved, would ease the current concern that Urbi is a cash-burning machine, and would thus, in our view, be positive catalysts for the stock. Valuation and Risks to Investment Thesis: As a result of the significant underperformance of the stock price, Urbi is trading at an estimated FV/EBITDA of 9.2 times for 2008. The FV/EBITDA premium to the sector average has narrowed from 48% in December to 18% currently and in terms of P/E 2008E the premium has reduced to 3%. Our 2008YE target price is based on a DCF valuation using a 9.2% discount rate and a 2.5% terminal growth rate, and implies a target FV/EBITDA multiple of 10.6 times for 2008. Risks to our investment thesis include: changes in the lending activity of mortgage agencies and commercial banks, delays in collections, increases in the cost of building materials, higher-than-expected increases in debt, and changes in fiscal regulations. * Employed by a non-us affiliate of Santander Investment Securities Inc. and is not registered/qualified as a research analyst under NASD rules.

Urbi: Debt to Grow at a Slower Pace Lowering Target Price but Reiterating Our Buy Urbi was founded in 1981 and is the second-largest housing developer in the affordable and middle-income segments in Mexico in terms of units sold. The company sold 37,231 units in full-year 2007 and generated revenues and EBITDA of US$1,171 million and US$319 million, respectively. Urbi is the leading housing developer in the northern region of Mexico, particularly in the States of Baja California, Sonora, Chihuahua, and Sinaloa. In addition, the company has recently expanded into the metropolitan areas of Mexico City, Guadalajara, and Monterrey. WHAT HAS CHANGED? Through April 29, Urbi s stock has significantly underperformed, posting a negative 8.3% return compared to a positive 20.1% by Geo and 18.9% by Homex. This underperformance is consistent with our concerns regarding the rapid growth of off-balance-sheet debt created by factoring of receivables and financing mortgages for customers through the Alternativa Urbi program, which resulted in the accumulation of off-balance-sheet liabilities of M$2.0 billion as of March 2008. The Alternativa Urbi program provides financing to clients who do not have the required credit capacity or cannot afford a down payment, such as workers in the informal sector. This program has contributed to Urbi s revenue growth but has also created concerns about the rapid increase in debt, and about the company accepting the credit risk associated with these customers, which is not a risk for other homebuilders. Furthermore, despite persistent efforts, the company has not been able to reach an agreement with a financial institution to share this risk. Finally, in our opinion, the significant negative free cash flow and fast-growing net debt since 2007 has contributed to Urbi s recent underperformance. In the 1Q08 press release, Urbi management stated that its investment in the Alternativa Urbi program has reached the M$2.0 billion level targeted by the company, and that it intends to maintain this level for the remainder of 2008. Furthermore, in its 1Q08 conference call, management said that it intends to increase revenues in the affordable-income segment, which has a shorter working capital cycle, from 55% in 2007 to 75% in 2008, consistent with the higher availability of financing in this segment. This should contribute to improving collection, reducing working capital requirements, and to maintaining debt stable at the current level of M$5.5 billion. In our opinion, this could reduce concerns about the pace of Urbi s rising debt. Finally, the company maintains its estimated EBITDA growth guidance unchanged at 16%-18% in 2008 and 2009, and 18%-20% for 2010 and 2011, with the aim of multiplying 2007 net earnings by 2.5 times over the next five years. In our opinion, a turnaround in operating cash flow and the stabilization of debt would both be positive in terms of stock prices. Figure 1.

QUARTERLY RESULTS Urbi released positive 1Q08 results on April 23, with sales and EBITDA growth at the high end of the housing sector in Mexico, and in line with our expectations. Revenues increased 21% YoY in nominal peso terms and EBITDA 21.4% YoY. The number of units sold increased by 8.2% YoY, reaching 7,755, of which 72.3% correspond to the affordable entry level, 20.2% in the low-to-middle-income segment, and 7.5% in the high-to-middle-income and residential segments. For full-year 2008, the company estimates that 75% of revenues will come from the affordable entry level and low middle income housing segments. The flat operating income reflects the changes made in accounting practices for the capitalization of the comprehensive cost of finance in COGS. Nevertheless, EBITDA, which excludes this effect, increased a solid 21.4% YoY with an EBITDA margin of 27.0%, at the high end of the sector. Net income grew 11.5% YoY and the net margin decreased from 13.8% to 12.8% in 1Q08 due to higher financial expenses. Net debt, including the liability provision for factoring, increased from M$2.12 billion in 4Q07 to M$2.97 billion in 1Q08, or M$854 million, equivalent to the reduction in cash during the quarter. The company s receivables turnover period remained stable at 188 days, according to our calculations, and the inventory turnover decreased from 522 days in 4Q07 to 503 days in 1Q08. The main use of cash was to reduce accounts payable by M$592 million. According to the company, its operating cash flow was a negative M$862.6 million in 1Q08. Figure 2.

REVISED EARNINGS ESTIMATES After incorporating 1Q08 results in our model, we are slightly increasing our EBITDA estimates for 2008 and 2009, which are in line with the growth estimated by the company. Nevertheless, after incorporating a faster-than-expected increase in debt and the additional shares issued in the October 2007 follow on equity offer into our valuation model, we are lowering our year-end 2008 target price for Urbi from M$55.00 (US$4.85) to M$41.50 (US$3.80) per share.

Urbi: Debt to Grow at a Slower Pace Lowering Target Price but Reiterating Our Buy VALUATION Our 2008YE target price is based on a DCF valuation using a 9.2% discount rate and a 2.5% terminal growth rate, and implies a target FV/EBITDA multiple of 10.6 times for 2008, similar to Urbi s trailing 12-month multiple. Despite the downward revision in our target price, the stock still offers a potential upside of 16% in U.S. dollars from current levels, and we are thus maintaining our Buy recommendation. As a result of the significant underperformance of the stock price, Urbi is trading at an estimated FV/EBITDA of 9.2 times for 2008. The FV/EBITDA premium to the sector average has narrowed from 48% in December to 18% currently and in terms of P/E 2008E the premium has been reduced to 3%. Figure 4.

RISKS In our opinion, the alternative Urbi schemes have contributed to revenue growth, but have also resulted in a fast-growing off-balance-sheet debt, which has raised some concerns among investors. Furthermore, when delivering the home before payment under the rent-to-own-program, Urbi incurred credit risks that other homebuilders do not, even though the risk is shared with the financial institution providing the mortgage. 6 Like other companies in the sector, Urbi is highly dependent on mortgages from government-related agencies for low-income housing, such as Infonavit and Sociedad Hipotecaria Federal. Changes in the lending policies by these agencies or changes in the payment period to homebuilders could affect Urbi. In the case of loans to the middle-income and residential segments, changes in interest rates or lending policies by commercial banks could also affect demand in this segment.

Because Urbi s main markets are located in the northern region of Mexico, the company also is more sensitive to changes in the U.S. economy and the export-oriented industry than its peers. Changes in U.S. economic activity could have a more significant impact on Urbi, but the company s geographical expansion should reduce this risk in the future, in our view. Strong growth in the sector could put pressure on the price of land in Mexico, and it is uncertain whether developers would be able to pass this increase through to their selling prices. However, companies with large land banks, such as Urbi, are less sensitive to this risk. Nevertheless, there is no certainty that the entire land bank will get the necessary permits from authorities or that the developments will be sold at the expected prices. In addition, permits and the need to build infrastructure sometimes result in delays and additional costs for developers.
