Madrid, April 9, 2025. The Board of Directors of Cox, a vertically integrated utility in water and energy, has agreed to initiate a share swap process targeted at specific shareholders of Cox Energy, which will continue to be listed on BIVA. This action is being carried out as outlined on page 151 of the information booklet for the company’s share subscription offer, registered in the Official Register of the CNMV on November 5, 2024, as amended by the supplement to the booklet approved and registered on November 12, 2024.

To execute the swap involved in this operation, the Board of Directors of Cox has decided that, at the forthcoming General Shareholders’ Meeting, a proposal will be made for a capital increase through a non-cash contribution of Cox Energy shares to the parent company, with a swap ratio of one share of Cox ABG Group S.A. for every five shares of Cox Energy, S.A.B. de C.V. contributed in the swap.

The Company notes that the operation is still under analysis, and it cannot guarantee that it will ultimately proceed or that the announced conditions will be maintained.
