Important legal information Investors are urged to read Endesa's Solicitation/Recommendation Statement on Schedule 14D-9 when it is filed with the U.S. Securities and Exchange Commission ("SEC"), as it will contain important information. The Solicitation/Recommendation Statement and other public filings made by Endesa with the SEC are available without charge from the SEC's website at www.sec.gov and at Endesa's principal executive offices. This presentation contains certain estimates or predictions ("forward-looking statements") regarding financial and operating statistics and results and other future events. These statements are not guarantees of future performance and are subject to material risks, uncertainties, changes and other factors that may be beyond Endesa's control or that may be difficult to predict. These forward-looking statements include, but are not limited to, information regarding: estimated future earnings; anticipated increases in wind and CCGTs generation and market share; expected increases in demand for and supply of gas; management strategy and goals; estimated cost reductions; tariffs and pricing structure; estimated investments; expected asset disposals; estimated increases in capacity and output and changes in capacity mix; repowering of capacity and macroeconomic conditions. For example, the EBITDA targets for 2007 to 2009 (which corresponds to gross operating profit in Endesa's IFRS financial statements) and the preliminary results for fiscal year 2006 included in this presentation are forward-looking statements that are based on certain assumptions that may or may not prove correct. The principal assumptions underlying these forecasts and targets relate to the regulatory environment, exchange rates, divestments, increases in production and installed capacity in the markets in which Endesa operates, increases in demand in those markets, allocation of production among different technologies, cost increases associated with a higher activity level not exceeding certain limits, the market price of electricity not falling below certain levels, the cost of CCGT and the availability and cost of gas, coal, fuel-oil and emission rights necessary to operate our business at desired levels. Furthermore, the 2006 preliminary results and other financial information is subject to completion of the Endesa's year-end accounting procedures and the audit process and, therefore, is subject to modifications during those processes and, in particular, as a result of possible regulatory developments that may take place before the Board of Directors issues financial statements and that may affect fiscal year 2006 or earlier. The following factors and circumstances, in addition to those discussed elsewhere in this presentation, could cause actual financial and operating results and statistics to differ materially from those expressed in our forward-looking statements, including the preliminary results for fiscal year 2006: Economic and Industry Conditions: significant adverse changes in the conditions of the industry, the general economy or our markets; the effect of the prevailing regulations or changes in them; tariff reductions; the impact of interest rate fluctuations; the impact of exchange rate fluctuations; natural disasters; the impact of more restrictive environmental regulations and the environmental risks inherent to our business; potential liabilities relating to our nuclear facilities. Commercial or Transactional Factors: delays in or impossibility of obtaining necessary regulatory, antitrust and other approvals for our proposed acquisitions or asset disposals, or any conditions imposed in connection with such approvals; our ability to integrate acquired businesses successfully; the challenges inherent in diverting resources and management's focus away from other strategic opportunities and from operational matters during the process of integrating acquired businesses; the outcome of any negotiations with partners and governments; delays in or impossibility of obtaining necessary authorizations or requalifications for our real estate assets; delays in or impossibility of obtaining regulatory authorizations, including those related to the environment, for the construction of new facilities, repowering or improvement of existing facilities; shortage of or changes in the price of equipment, material or labor; opposition of political or ethnic groups; adverse changes of a political or regulatory nature in the countries where we or our companies operate; adverse weather conditions, natural disasters, accidents or other unforeseen events; and the impossibility of obtaining financing at what we consider satisfactory interest rates. Governmental and Political Factors: political conditions in Latin America; changes in Spanish, European and foreign laws, regulations and taxes. Operating Factors: technical problems; changes in operating conditions and costs; capacity to execute cost-reduction plans; capacity to maintain a stable supply of coal, fuel and gas and the impact of price fluctuations of coal, fuel and gas; acquisitions or restructuring; capacity to successfully execute a strategy of internationalization and diversification. Competitive Factors: the actions of competitors; changes in competition and pricing environments; the entry of new competitors in our markets. Further details on the factors that may cause actual results and other developments to differ significantly from the expectations implied or explicitly contained in the presentation are given in the Risk Factors section of Form 20-F filed with the SEC and in the Registration Document of Endesa Stock filed with the Spanish National Securities Regulator. No assurance can be given that the forward-looking statements in this document will be prove correct. Except as may be required by applicable law, neither Endesa nor any of its affiliates intends to update these forward-looking statements.
