12 STOCK PRICE PERFORMANCE Source: Infosel Financiero COMPANY DESCRIPTION Grupo Industrial Saltillo, S.A. is a Mexican holding company with three business divisions. Founded in 1928 when Isidro López Zertuche and his brothers Carlos and Ricardo started a laminated metal products factory. In 1975 the company name was changed to its current name and in 1985 the legal form was changed to variable capital. In 1976 it became a listed company in the Mexican Stock Exchange (BMV) with the ticker symbol GISSA and current series *. Its ADRs trades at the over the counter market since March 2000 under the name GISQY. The company has joint ventures with foreign companies Nork Hydro Aluminum, Metal Technologies, and NPL. GISSA have subsidiaries in several locations across the country and employs 11,071 people. The company is a conglomerate of three business units: Metal mechanical Building Materials Housewares Sales Sales by Division at III Quarter 2004 12% 53% 47% Domestic Foreign 44% 44% Metal and Automotive Building Materials Housewares Source: GISSA 2

Metal Mechanical Division This business includes the manufacturing of gray cast iron, ductile iron, and aluminum for monoblocks, motor heads and auto parts. The automotive metal mechanical has the following companies: 1. Castech: Aluminum blocks and heads for internal combustion engines. 2. Cifunsa: Iron engine blocks and heads for diesel and gasoline motors. Tech Matec and Ditemsa: The first manufactures automation systems for manufacturing processes and the second produces plastic injection moldings and tools. They help round up Castech and Cifunsa operations. In order to supply General Motors, a new plant of Castech starts operations in 2005 with a US$ 20 million investment. This project employing 200 people- will support Castech s growth by increasing exports to Canada and Australia; for this last country, daily exports account for 1,200 motor heads and 600 aluminum blocks. As for Cifunsa, the group invested US$ 11 million in June 2004, to expand the heart pack area for Toyota, a new GISSA customer. The strategy of this division is focus on developing new customers such as Toyota, Nissan, Ford and VW, a business increase with John Deere and Caterpillar as well as an increase of the performance and focus on larger margins products. During the third quarter of 2004, this division contributed with 44% of consolidated sales, an increase of 68% versus 2003 and 25% against third quarter of 2003 and a 15% as compared to the second quarter of 2004. All of this was due to its US customers, John Deere and Caterpillar, the consolidation of the EV-6 project with GM and the start of the new automotive ductile iron plant. Accumulated nine months sales had an increase of 45% versus last year s same period. However, EBITDA fell 14% as compared to the second quarter but a growth of 23% year to year. Building Materials Division This division manufactures ceramic tiles, water and air heaters, as well as markets bathroom fixtures, with two companies: 1. Vitromex: Manufactures and markets ceramic tiles and bathroom fixtures. Sales for the domestic market trough Vitromex and Artemis brands and the US market with Vitromex USA and St. Thomas Creations brands. 2. CINSA Boilers: Manufactures water heaters with three brands for different market niches: Cinsa Boilers, Cal-o-Rex, and Heat Master. In August 2004, a new VITROMEX plant was opened in Chihuahua, with an investment of US$ 42 million. It was planned to begin operations until 2005, but an increasing demand forced the start of operations ahead of schedule. Since 1998, the ceramic tiles, bathroom fixtures, and water heaters segment has invested an amount of US$ 110 million for the manufacturing plants located in the states of Guanajuato and San Luis Potosí. 3

This division strategy is focused on developing new products, migrate operations to more efficient plants and an increased regional penetration as well as an increase in exports. At the third quarter of 2004, revenues of this division were 44% of net consolidated sales. Comparing results of this quarter with the same period in 2003 revenues grew up 5% however, operating income decreased 10%, due to increases in raw materials costs, the start up of the Chihuahua plant, and an unexpected provision of US$ 0.9 million, as well as the re-launching of some bathroom fixtures brands in the US market. EBITDA by Division III Quarter 2004 1% 34% Metal and Automotive Building Materials 65% Housewares Source: GISSA Housewares Division This division manufactures and markets stainless steel, steel enamel, and aluminum kitchenware as well as ceramic ware, through four subsidiaries: 1. Cinsa: Stainless steel, steel enamel, novacero, and aluminum kitchenware and tableware. 2. Enasa: Stainless steel, porcelain, and enamel steel non stick kitchenware, pots, and pans. 3. Esvimex: High quality enamel for the ceramic industry. 4. Santa Anita: Household and institutional ceramic ware. During the last two years, GISSA has been forced to lower prices due to the intense competition by increasing imports of Chinese and South American products. In order to maintain competitiveness and increase profitability margins, the conglomerate has increased quality standards and streamlined production processes. On the other hand, Enasa will invest a million dollars in the development of a new production line, which will strengthen the production of non stick pans. At the third quarter of 2004, this division sales were 12% of consolidated net revenues (Ps$ 234 million). Comparing the third quarter of 2004 with the same period of 2003, division sales decreased 3%, operating losses amounted to Ps$ 10 million, and EBITDA decreased 92% year-to-year. GISSA Overall Strategies Implementation of a quality model for goals and objectives achievement: transformation map towards a competitive organization, supported by tools such as Kaizen and information technologies. 4

Financial Summary GISSA consolidated sales at the third quarter of 2004 were Ps$6,181 million, an increase of 18.2% year to year; 47% of total sales are domestic and the remaining 53% are exports. During the last quarter, GISSA made investments of US$18 million for new projects and maintenance.

Recovery of the US economy is other variable that explains this division performance; sales of this division account for 44% of consolidated net revenues. Sales for last quarter of 2004 are also expected to improve due to the demand of steel blocks and heads by Chrysler, as well as new orders placed by Toyota, a client with whom GISSA recently signed an agreement.

Performance of the water heaters and ceramic tiles business is outstanding; revenues increased for these businesses in 12 and 7%, respectively, due to the economic recovery of the Mexican and US markets. The scenario for this division is positive due to several factors, among them, increased sales pushed by the federal government housing program, consolidation of ceramic tiles marketing strategies, the increase in water heaters and ceramic tiles exports to US, all this supported by the lowest interest rates in modern history of Mexico. Recently, this economic sector has experienced the greatest historical growth. 6

GISSA opened in June 2004 the VITROMEX plant in Chihuahua, which will increase production capacity by 20%. This will allow meeting the existing demand of ceramic tiles. Consolidated cost of sales had an increase of 23.5% compared to the same period of 2003, due to, among other reasons: exchange fluctuation from operations in some of the divisions of the group, as well as the increase in some commodities; steel and iron scrap had price increases of 60% during the year. This was the cause of operating income decrease by 19% compared to 2003. Steps to correct inefficiencies in the plant capacity utilization and reduction of implicit costs have been taken. EBITDA was Ps$905 millions, an increase of 9% compared to the same period of 2003. It is important to mention that the Company has taken steps towards correction of inefficiencies in plant utilization thereby reducing implicit costs. 20.00 18.00 16.00 14.00 12.00 10.00 8.00 6.00 4.00 2.00 0.00 III_1999 III_2000 III_2001 III_2002 III_2003 III_2004 4.00 3.50 3.00 2.50 2.00 1.50 1.00 0.50 0.00 Interest Coverage Long Term Liabilities/EBITDA Source: Prepared with information from Infosel Inversionista INDUSTRY ANALYSIS Metal-Mechanical Industry This industry is cyclical and its performance depends basically on automobiles demand. Since the US is one of the largest consumers, this industry is tightly related with the economic growth of that country. This industry is under several risks, challenges, and threats. One of the most important is the constant is the variation on manufacturing costs (iron, steel, energy, natural gas) prices, together with the permanent capital investment needs to keep a competitive position in the market. Recently, the Mexican Automotive Industry Association stated that the production of January-August 2004 increased 9% (146,065 units), 4.4% lower than that for the same period in 2003. In August, export units were 110,050, accounting for 79% of total production. Although the number of units of last year has not been exceeded, recovery in the following months is expected. 7

In this area, GISSA has continues to invest strongly in its iron and aluminum blocks manufacturing plants, and given that the automotive industry is growing, this division is expected to generate the largest portion of revenues in the group. In this regard, last March, the Secretary of Economy authorized a decrease in customs duties for steel imports from countries with whom Mexico does not have free trade agreements. This will benefit GISSA by allowing an increase of its suppliers portfolio and improving operating margins thanks to raw materials costs reduction. As of the third quarter, Mexican economy shows a GDP growth of 4.4%, compared to same period of 2003. This increase is explained by a high performance of industrial activity, which includes outstanding improvement of manufacturing activity (5.0%). An increase in exports and improvement in employment levels had a favorable effect on this industry. Mexico Gross Domestic Product (Annual Variation %) Source: INEGI and Santander That, as well as the US economy strength. According to Banamex, the US economy has performed according to the beginning of 2004 analysts expectations with an increase of the GDP grater than last year s 3%. Such increase was achieved notwithstanding higher oil prices and the fact that at the second semester there were not important fiscal aids. Analyst s expectations set end of year GDP growth at 4.4%. The industrial sector has been benefited by this set of conditions, as is the case of the car manufacturing sector. For example, from the first to the second semester of 2004, there was an increase greater than 15% 8

in the light vehicle and it is expected a slight increase for the next year. This is also supported by an increase in car loans due to lower interest rates and better economic conditions as mentioned before. Altogether, this imply growth opportunities for GISSA, since more than 50% of its sales are exports. However, Brazil is a latent threat in the production of specialized auto parts, and intends to expand to markets such as Germany, Hungry, and Argentina, projecting exports of US$ 100 million by 2007. But actual pressure comes from the fact that the American market prompted Sabo Company to invest US$ 10 million in Brazil to build a second facility that will serve General Motors, which is GISSA s main client. Construction Industry GISSA is an active participant in the building material sector, that has enjoyed a dynamic behavior in the last years. Due to demographic tendencies and plans that support housing construction, Mexican government forecasts that housing demand will grow during the next twenty five years, and is planning to build approximately twenty million houses. According to INEGI s projections for 2005, federal support will amount to Ps$ 126.3 million, both for financing the acquisition and house improvements, which represents an actual growth of 4.5% compared to current year. This industry has grown considerably; according to Lloyd s economic report, listed companies in the house construction industry experienced a 55% growth as of June 2004. During April-June 2004 alone, 21,116 houses were built, and by the end of the year, an above 14% growth for the housing industry is expected. 0.05 0.04 0.03 0.02 0.01 0 1995 1997 Source: CONAPO Tasa de crecimiento anual de viviendas Annual particulares growth rate of en households Mexico in Mexico 1999 2001 2003 2005 2007 2009 2011 2013 2015 2017 2019 On another hand, INEGI forecasts that demand for houses during 2004 2006 will be around 2.1 million units, while 1.1 million households will require repair and maintenance. Demand is focused mainly in five states: Estado de Mexico 21.2%, Baja California 7%, Veracruz 6.9%, Jalisco 6.6%, and D.F. 5.8%. Although the construction industry in Mexico appears promising, it is not feasible to stimulate the housing purchases without the necessary economic conditions that include attractive interest rates. For example, mortgage loans rates in Mexico, both medium and long-term, have decreased dramatically to below 15%. Last year, only 489 thousand houses were purchased through some form of financing and by the end of the year this amount is expected to reach 575 thousand units. Another factor is about the tax benefits for financial expenses on individuals mortgages, together with fierce competition among banks and other financial institutions. 9

It is important to mention that in Mexico, financing for the purchase of low value houses is dominated by INFONAVIT, who has granted 1.8 million loans in the last three years and plans to increase credits 11.1% per year during the next five years. If this rate continues, INFONAVIT will be the largest mortgager in North America. Anticipating the mortgage bonanza, several participants appear to be interested in opportunities that the market of housing loans will offer. A clear example is that Grupo BBVA Bancomer acquired last September, 100% of Hipotecaria Nacional, the largest private mortgage company in Mexico. Hipotecaria Su Casita, another important mortgage company in the country, started offering mortgages in Mexican pesos through its office in Denver, Colorado. This will allow Mexican residents in the US to finance the acquisition of a house for their relatives in Mexico. Money transfers sent to Mexico by Mexican residents in the US are an estimated US$ 13.3 million and are directed to purchasing non essential goods instead of acquiring a house. This represents an attractive potential market. On the other hand, goods and services offered increased 5.8% in actual terms from April to June 2004 due to imports. Also, wholesale and retail sales have grown 11.1% and 8.2% respectively, compared to the previous quarter. This was due to middle class consumption financed by personal loans. The largest demand was in chemical, electric material, and home products. Based on the above and according to housing industry forecasts, prosperity and several opportunity areas are foreseen for the Vitromex division in the medium and long term. Home Products Industry This division accounts for the smallest share of the group s revenues (12%). Due to its low production and marketing costs, China is a threat not only for GISSA, but for the Mexican industry in general. China s competitive advantage endangers the Mexican domestic industry. Therefore, Mexican government has taken drastic measures, such as increasing compensatory quotas for the imports of Asian tableware, which in the current year were 95.06%-99.81%, compared to 23%-26% rates prevailing in 1992. On the other hand, final goods and services consumer expenditures grew 5.4% from April to June, 2004 in real terms, including home products, communication, financial services, etc. Macroeconomic Issues During the year, inflation was higher than expected particularly August, September, and October. The increase was due to increments in energy and vegetables (tomato) prices. Also, there were considerable increase in utilities along the rise of international prices of raw materials and energy; domestic gas prices, oil, and several raw materials are based on international prices. October is the latest inflation rate known, with an increase of 0.69 percent equivalent to an annual rate of 5.40 percent. 10

Source: A NYMEX Natural Gas Future contract According to Banxico s latest survey, an increase in consumer prices of 0.62 percent and 0.37 percent are expected for November and December. Analysts estimate an inflation rate of 5.18 percent for 2004, and a underlying inflation rate of 3.85 percent.

Financial soundness: Notwithstanding some difficulties at some divisions, due to outside factors, they have financial soundness and growth in sales. Client development: Asian car companies contracts allow GISSA to hedge risks among car companies Consistent investment: During 2004, GISSA has invested US$ 58 million, with a portion employed in plants maintenance and the remaining for new plants construction. Opening of the VITROMEX and CIMETECH plants are part of this strategy. Indebtedness: According to our projections, total debt ratio will reach its maximum level by the end of this year (53%), and starting next year it will gradually decrease to 39%, mainly by the return of investment in plants, and revenues that will be generated with the increased capacity. Strong management: Measures related to corporate governance that were implemented in 2002 are consolidating the image of the group and strengthening its principles of austerity, labor ethics, and commitment. Quality: GISSA holds important agreements with global clients that endorse product quality of the conglomerate from Saltillo. GISSA operations follows world class quality standards and information technology that support the organization s competitiveness. GISSA has also set continuous improvement practices through the Kaizen quality model. 14

RISK ANALYSIS Volatility in input prices GISSA uses raw materials -such as steel, copper, aluminum, and gas- that have international set prices therefore, its manufacturing costs structure is affected by these variations. These costs cannot be controlled, but their repercussions can be attenuated. Government Reforms Lack of legal reforms, specially it the electric sector, inhibits performance to the companies that are part of GISSA. Energy has a high impact into operative costs. Stagnation affecting the energy reform has a negative repercussion in GISSA s (and other manufacturing companies) competitiveness. Dependency on energy has a direct impact on operating costs. Concentration of Clients A GISSA plant located in the outer limits of Saltillo is focused in manufacturing motor heads and hearts, and total production is destined to only one client: General Motors. This dependency is a risk for the company, because its sales and exports are important to the group. Diversifying clients should be considered. Investment Requirements GISSA participates in very competitive markets that demand consistent capital investment. If competitors continue to enter, prices of products would decrease, and therefore, operating margins would also decrease. Cyclical Demand of Products Products offered by GISSA show cyclical demand. This is due to economic situation of the countries in which GISSA is present. Many factors are not under the control of GISSA and this has a strong impact on the capital investments required to stay competitive. INVESTMENT SUMMARY Target price valuation was calculated using the discounted cash flows method or relative valuation. The target price obtained was $21.88, therefore we are rating the stock as MARKET OUTPERFORM. 15

The Latin America Burkenroad Reports are financial analysis of companies listed in the Mexican Stock Exchange, and capital budgeting of medium and small companies. They are elaborated by students of the Bachelor of Financial Management and Accounting & Finance, under the supervision of professors from the Accounting and Finance Department of ITESM, Monterrey Campus. The ITESM, Instituto de Estudios Superiores de Administración de Venezuela (IESA), and Universidad de los Andes de Colombia, along with Tulane University, carry out the Latin America Burkenroad Program. This project is granted by the Multilateral Investment Fund of the Interamerican Development Bank. This program enriches human capital by providing training in financial analysis techniques, and also intends to facilitate access of companies to financing sources by providing financial information to investors and financial institutions. The reports prepared by this program, evaluate financial conditions and investment opportunities in Latin American companies. Financial reports of listed companies are distributed to national and foreign investors through publications and financial information systems such as Infosel Financiero and Finsat, among others. Investment capital budgeting reports, are distributed only to beneficiary companies for future private presentations to financial institutions or potential investors. Investment plans and financial situation, of the analyzed companies are presented to the financial community in an Annual Meeting.
