Our renewable assets generated solid operating results during the nine-month period ended September 30, 2017. Our fleet of solar assets in Spain continued to deliver good levels of electricity generation thanks to high solar radiation in the region. In the U.S., after a very good first half of 2017, production was impacted in the third quarter by an incident in electric transformers in Solana, which caused the plant to produce at a reduced capacity in July and part of August; all the necessary repairs were completed in August. Kaxu, our solar asset in South Africa, continued to perform at lower-than-expected levels, while we carried out required repairs, which were completed in the fourth quarter of 2017. Finally, in our wind assets, energy generation was significantly higher than in the same period of 2016.

ACT, our cogeneration plant in Mexico, demonstrated high levels of availability during the nine-month period ended September 30, 2017. In transmission lines, availability was high in the third quarter of 2017 and revenues and EBITDA remained stable. Finally, our water assets continue to deliver steadily strong levels of availability.

¹² Further Adjusted EBITDA includes our share in EBITDA of unconsolidated affiliates and the dividend from our preferred equity investment in Brazil or its compensation (see reconciliation on page 17).

Liquidity and Debt

Our total liquidity as of September 30, 2017 is $880.6 million and consists of $794.1 million of consolidated cash and cash equivalents, of which $197.1 million was available at the Atlantica corporate level, and $86.5 million of cash classified as short-term financial investments at the project level.

As of September 30, 2017, net project debt amounted to $4,982.6 million and net corporate debt amounted to $503.8 million. The net corporate debt / CAFD pre-corporate debt service ratio¹³ improved to 2.3x compared to 2.7x as of December 31, 2016.

Net project debt is calculated as long-term project debt plus short-term project debt minus cash and cash equivalents at the project level. Net corporate debt is calculated as long-term corporate debt plus short-term corporate debt minus cash and cash equivalents at the Atlantica Yield corporate level.

Strategic partnership with Algonquin

As we announced on November 1, 2017, we have entered into a non-binding term-sheet with respect to strategic agreements¹⁴ with Algonquin Power & Utilities Corp. (“Algonquin”) which we believe will define the beginning of a new phase for Atlantica, opening new growth opportunities.

Algonquin announced on November 1, 2017 that it reached an agreement¹⁵ with Abengoa to acquire a 25% stake in Atlantica from Abengoa at a price of $24.25 per share, which implies a total equity value of Atlantica Yield of $2,430 million. After the closing of this transaction, Algonquin will be Atlantica’s largest shareholder. Abengoa has communicated that it intends to sell its remaining 16.5% stake in Atlantica over the upcoming months in a private transaction, subject to approval by the US Department of Energy. Algonquin has an option to purchase this remaining stake until March 2018.

¹³ Based on midpoint CAFD guidance before corporate debt service for the year 2017.

¹⁴ 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.

¹⁵ The purchase of Atlantica shares by Algonquin from Abengoa is subject to a number of conditions, most of which are beyond our control.

In addition, Algonquin and Abengoa announced that they signed an agreement to create a joint venture called AAGES to invest in the development and construction of contracted clean energy and water infrastructure assets.

In the context of these agreements, Atlantica signed a non-binding term-sheet with Algonquin and Abengoa aimed at enhancing Atlantica’s growth opportunities, which will serve as the basis of a shareholders’ agreement to be executed on or before the closing of the purchase of the 25% interest by Algonquin and reflecting the following initiatives:

Proposed Right of First Offer (“ROFO”) Agreement between AAGES and Atlantica

Proposed agreement to periodically discuss the sale of North American assets to Atlantica

Proposed opportunity for Algonquin to provide, through the subscription of ordinary shares of Atlantica, incremental equity of $100 million for the acquisition of new assets by Atlantica. Algonquin has been granted certain preferred rights when participating in further equity issuances with the possibility of increasing Algonquin’s ownership in Atlantica up to 41.5%

Proposed right of Algonquin to appoint a number of directors corresponding to Algonquin’s percentage ownership, with a maximum of less than one half of the total

Maintain 80% target dividend payout ratio for Atlantica

We believe that Algonquin, an industrial North American company listed on the Toronto and New York stock exchanges, will be an ideal sponsor for Atlantica. The new proposed ROFO represents an excellent growth opportunity for Atlantica, as it strengthens visibility on our near-term growth and provides a line of sight to long-term growth. In addition, Algonquin’s intention to lead future equity issuances will anchor the financing of future acquisitions.

Waivers and consents

In October 2017, we obtained a waiver from the ACT project finance lenders to delete the minimum ownership clause related to Abengoa.

In November 2017, we signed a consent with the US Department of Energy which reduces the minimum ownership required by Abengoa in Atlantica to 16%, subject to certain conditions precedent.

Dividend

On November 10, 2017, our Board of Directors approved a dividend of $0.29 per share, which represents an increase of 12% from the prior quarter and 78% increase from the third quarter of 2016. The dividend is expected to be paid on or about December 15, 2017 to shareholders of record as of November 30, 2017.

New NASDAQ Ticker Symbol

The Atlantica ticker symbol on NASDAQ will change from “ABY” to “AY” effectively tomorrow, November 14, 2017. The CUSIP number will remain the same.

Non-GAAP Financial Measures

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.

We define Further Adjusted EBITDA including unconsolidated affiliates as profit/(loss) for the period attributable to the Company, after adding back loss/(profit) attributable to non-controlling interest from continued operations, income tax, share of profit/(loss) of associates carried under the equity method, finance expense net, depreciation, amortization and impairment charges, and dividends received from the preferred equity investment in ACBH.

Our management believes Further Adjusted EBITDA including unconsolidated affiliates is useful to investors and other users of our financial statements in evaluating our operating performance because it provides them with an additional tool to compare business performance across companies and across periods. This measure is widely used by investors to measure a company’s operating performance without regard to items such as interest expense, taxes, depreciation and amortization, which can vary substantially from company to company depending upon accounting methods and book value of assets, capital structure and the method by which assets were acquired. Further Adjusted EBITDA including unconsolidated affiliates is also used by management as a measure of liquidity.

Our management uses Further Adjusted EBITDA including unconsolidated affiliates as a measure of operating performance to assist in comparing performance from period to period on a consistent basis and to readily view operating trends, as a measure for planning and forecasting overall expectations and for evaluating actual results against such expectations, and in communications with our Board of Directors, shareholders, creditors, analysts and investors concerning our financial performance.

We define Cash Available For Distribution as cash distributions received by the Company from its subsidiaries minus all cash expenses of the Company, including debt service and general and administrative expenses. Management believes cash available for distribution is a relevant supplemental measure of the Company’s ability to earn and distribute cash returns to investors.

We believe cash available for distribution is useful to investors in evaluating our operating performance because securities analysts and other interested parties use such calculations as a measure of our ability to make quarterly distributions. In addition, cash available for distribution is used by our management team for determining future acquisitions and managing our growth.
