 DISCLAIMER  Forward Looking StatementsThis 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. Except as required by law, we do not undertake any obligation to update any forward-looking statements to reflect events or circumstances after the date hereof or to reflect the occurrence of anticipated or unanticipated events or circumstances.Investors should read the section entitled "Item 3D. Key Information—Risk Factors" and the description of our segments and business sectors in the section entitled "Item 4B. Information on the Company—Business Overview", each in our annual report for the fiscal year ended December 31, 2018 filed on Form 20-F, for a more complete discussion of the risks and factors that could affect us.Forward-looking statements include, but are not limited to, statements relating to: uncertainties in emerging markets where we have international operations; statements related to project growth strategy; commitments to increased DPS and accretive investment opportunities; strategic business alternatives to ensure optimal company value and improve shareholder return; intentions to internalize O&M in our U.S. solar and wind assets in Uruguay; estimated returns and cash available for distribution (“CAFD”) estimates from project debt refinancing; projected future CAFD yield; cash available for distribution estimates made in reliance on asset performance and assets reaching COD by the expected date; fluctuations in the cost of energy and gas; predictions and estimates regarding global water demand, power generation, renewable energy, water desalination markets and related investments; strategies in the event of Mojave distribution delays based on the PG&E default; ESG initiative improvement; the quality of our long-term contracts; self-amortizing project debt structure and related debt reduction; expected U.S. growth, the use of non-GAAP measures as a useful predicting tool for investors; the possibility to extend asset life; and various other factors, including those factors discussed under “Item 3.D—Risk Factors” and “Item 5.A—Operating Results” in our Annual Report for the fiscal year ended December 31, 2018 filed on Form 20-F.For the purposes of the announced transactions, CAFD yield is the annual weighted average of CAFD expected to be generated by the investments over their first 10-year period from 2019, or from COD for those assets which are not yet in operation, divided by the expected acquisition price. CAFD Yield is an internal estimation subject to a high degree of uncertainty and our ability to reach this expected CAFD Yield depends on a variety of factors, including closing of the acquisitions on their expected terms, acquired assets performing as expected, acquired assets making cash distributions to the holding level as expected, and assets reaching COD by the expected date. Furthermore, any dividends are subject to available capital, market conditions, and compliance with associated laws and regulations. These factors should be considered in connection with information regarding risks and uncertainties that may affect our future results included in our filings with the U.S. Securities and Exchange Commission at www.sec.gov. We undertake 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.The CAFD and other guidance included in this presentation are estimates as of February 28, 2019. These estimates are based on assumptions believed to be reasonable as of the date Atlantica published its FY 2018 Financial Results. Atlantica disclaims any current intention to update such guidance, except as required by law.Non-GAAP Financial Information This presentation also includes certain non-GAAP financial measures, including Further Adjusted EBITDA including unconsolidated affiliates, Further Adjusted EBITDA including unconsolidated affiliates as a percentage of revenues (margin) and CAFD. Non-GAAP financial measures are not measurements of our performance or liquidity under IFRS as issued by IASB and should not be considered alternatives to operating profit or profit for the period 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. Please refer to the appendix of this presentation for a reconciliation of the non-GAAP financial measures included in this presentation to the most directly comparable financial measures prepared in accordance with IFRS as well as the reasons why management believes the use of non-GAAP financial measures in this presentation provides useful information.
