Abengoa Yield announces a reinforcement of its ROFO agreement, a MoU signed with Abengoa on its corporate governance and the beginning of negotiations for a third acquisition from Abengoa

December 11, 2014

December 11, 2014.- Abengoa Yield (NASDAQ: ABY), the sustainable total return company that owns a diversified portfolio of contracted assets in the energy and environment sectors, announced today that it has signed a call option agreement with Abengoa to purchase up to $100 million in contracted assets at a 12% yield during the year 2015, subject to certain conditions. The acquisition under this call option agreement will constitute the third acquisition, if executed, from Abengoa.

On November 14, 2014, Abengoa Yield announced updated dividend per share guidance of $1.60 for the year 2015 and $1.92 to $2.00 for the year 2016. This guidance assumes the first acquisition from Abengoa for a price of $312 million and a second acquisition currently under negotiation. The third acquisition, to be executed under the call option agreement, is therefore not considered in our current dividend per share guidance

In addition, Abengoa Yield has signed a Memorandum of Understanding with Abengoa under which both companies agree to work to take the appropriate steps to ensure that Abengoa Yield’s board of directors has a majority of independent directors and to increase the list of matters that require approval by the board of directors.

Finally, Abengoa Yield has signed an amendment to the Right of First Offer (“ROFO”) Agreement with Abengoa to include, among other modifications, a right for Abengoa Yield to “call” assets for negotiation, once those assets reach eighteen months of operation.

Santiago Seage, Abengoa Yield’s CEO, said: “With the potential second and potential third acquisitions from Abengoa we aim to accelerate our growth, while making Abengoa Yield a more independent company that will continue growing accretively thanks to a reinforced ROFO agreement with a leading global developer like Abengoa and to third party acquisitions”.
