This presentation contains forward-looking statements. These forward-looking statements include, but are not limited to, all statements other than statements of historical facts contained in this presentation, including, without limitation, those regarding our future financial position and results of operations, our strategy, plans, objectives, goals and targets, future developments in the markets in which we operate or are seeking to operate or anticipated regulatory changes in the markets in which we operate or intend to operate. In some cases, you can identify forward-looking statements by terminology such as “aim,” “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “guidance,” “intend,” “is likely to,” “may,” “plan,” “potential,” “predict,” “projected,” “should” or “will” or the negative of such terms or other similar expressions or terminology. By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future. Forward-looking statements speak only as of the date of this presentation and are not guarantees of future performance and are based on numerous assumptions. Our actual results of operations, financial condition and the development of events may differ materially from (and be more negative than) those made in, or suggested by, the forward-looking statements.The purchase of Atlantica shares by Algonquin from Abengoa is subject to a number of conditions, most of which are beyond our control. Atlantica cannot make any representation regarding an agreement reached by two third parties. The term-sheets entered into with Algonquin, AAGES and Abengoa are non-binding and while the parties have agreed to negotiate in good faith towards a mutually beneficial outcome, there is no guarantee that the AAGES ROFO and other agreements will be entered into, or that any assets will be purchased by Atlantica from Algonquin, AAGES or Abengoa.Many factors could cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements that may be expressed or implied by such forward-looking statements, including, among others: difficult conditions in the global economy and in the global market and uncertainties in emerging markets where we have international operations; changes in government regulations providing incentives and subsidies for renewable energy, including reduction of our revenues in Spain, which are mainly defined by regulation through parameters that could be reviewed at the end of each regulatory period; political, social and macroeconomic risks relating to the United Kingdom's potential exit from the European Union; changes in general economic, political, governmental and business conditions globally and in the countries in which we do business; decreases in government expenditure budgets, reductions in government subsidies or adverse changes in laws and regulations affecting our businesses and growth plan; challenges in achieving growth and making acquisitions due to our dividend policy;

our ability to consummate future acquisitions from Abengoa, AAGES, Algonquin or others; changes in our tax position and greater than expected tax liability; our ability to use U.S. NOLs to offset future income may be limited, including the possibility of experiencing an “ownership change” as defined under Section 382 of the U.S. Internal Revenue Code; conflicts of interest which may be resolved in a manner that is not in our best interests or the best interests of our minority shareholders, potentially caused by our ownership structure and certain service agreements in place with our current largest shareholder; impact on the stock price of the Company of the sale by Abengoa of its stake in the Company and potential negative effects of a potential sale by Abengoa of its stake in the Company or of a potential change of control of the Company or of a potential delay or failure of a sale process; failure by Abengoa and Algonquin to close the agreement reached between both parties on November 1, 2017, for the acquisition by Algonquin of a 25% stake in Atlantica from Abengoa, including its potential negative impact on our stock price;

These factors should be considered in connection with information regarding risks and uncertainties that may affect Atlantica Yield’s future results included in Atlantica Yield’s filings with the U.S. Securities and Exchange Commission at www.sec.gov. Atlantica Yield undertakes no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or developments or otherwise.Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described herein as anticipated, believed, estimated, expected or targeted.This presentation includes certain non-GAAP (Generally Accepted Accounting Principles) financial measures which have not been subject to a financial audit for any period. We present non-GAAP financial measures because we believe that they and other similar measures are widely used by certain investors, securities analysts and other interested parties as supplemental measures of performance and liquidity.The non-GAAP financial measures may not be comparable to other similarly titled measures of other companies and have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our operating results as reported under IFRS as issued by the IASB. Non-GAAP financial measures and ratios are not measurements of our performance or liquidity under IFRS as issued by the IASB and should not be considered as alternatives to operating profit or profit for the year or any other performance measures derived in accordance with IFRS as issued by the IASB or any other generally accepted accounting principles or as alternatives to cash flow from operating, investing or financing activities.The CAFD and other guidance included in this presentation are estimates as of November 13, 2017. These estimates are based on assumptions believed to be reasonable as of that date. Atlantica Yield plc. disclaims any current intention to update such guidance, except as required by law.
