As of December 12, 2006 the company does not maintain its own shares in a self-portfolio, nor has acquired any of its own shares during fiscal year 2006.

The General Stockholders' Meeting held on April 15, 2007 agreed to authorizing the Board of Directors for derivative acquisition, via exchange dealing, of shares of the company itself, either directly, or through Subsidiary Companies of shares held up to the maximum foreseen limit in legal resolutions at a price ranging from twenty cents of a euro (120.20 euros) maximum per share, being able to make use of this authority during a period of eighteen (18) months from the same date, and subject to the contents of the Fourth Section of Chapter IV of the Rewritten Text of Corporate Law, revoking to the effect, expressly, authorization conferred to the Board of Directors, with the same aims, in accordance with the agreement adopted by the General Stockholders' Meeting held on June 29, 2003.

On September 15, 2004, Abengoa's Board of Directors determined, based on company stock quotes on that date, around 7 euros per share over the last quarter, that it did not reflect the real growth potential of the Company and deemed beneficial for the company, from a financial standpoint, to invest in its own shares. Nevertheless, taking into account that the company is, by definition, a shareholder that possesses more information than the rest of the market and that, even unintentionally, its operations can influence company stock quotes, the corresponding rules and cautions, with the aim of ensuring that it does not have an artificial influence on price establishment. Thus, making use of the authority conferred by the General Meeting, the Board of Directors ordered a plan for acquiring its own shares, allocating an amount for purchasing shares of Abengoa, S.A. itself; not to exceed 15 million euros in this fiscal year; in no case to exceed 5% of the share capital, nor will a price of more than 7.25 Euros per share be paid, subject to regulations contained in Title VII of Law 24/1988 pertaining to Securities Exchange in Abengoa's Internal Regulations of Conduct with respect to Securities Exchange and the guidelines contained in the present agreement; as orientating criteria for self-portfolio management, the rules contained in Circular Letter 12/1998 from the National Securities Exchange Commission dated December 17, 1998 are to be followed as well.
