This Amendment No. 5 (“Amendment No. 5”) amends the Statement on Schedule 13D filed on June 24, 2015 (the “Original Schedule 13D”), the Amendment No. 1 to the Original Schedule 13D filed on June 30, 2015 (“Amendment No. 1”), the Amendment No. 2 to the Original Schedule 13D filed on July 13, 2015 (“Amendment No. 2”), the Amendment No. 3 to the Original Schedule 13D filed on September 29, 2015 (“Amendment No. 3”) and the Amendment No. 4 to the Original Schedule 13D filed on October 29, 2015 (together with the Original Schedule 13D, Amendment No. 1, Amendment No. 2, Amendment No. 3 and this Amendment No. 5, the “Schedule 13D”) and is jointly filed by the Reporting Persons (as defined in the Original Schedule 13D) with respect to the ordinary shares of Abengoa Yield plc, nominal value of $0.10 per share (the “Ordinary Shares”). Unless otherwise indicated, each capitalized term used but not otherwise defined herein shall have the meaning ascribed to such term in the Original Schedule 13D. This Amendment No. 5 amends the Original Schedule 13D, Amendment No. 1, Amendment No. 2, Amendment No. 3 and Amendment No. 4 as specifically set forth herein.

This Amendment No. 5 is being filed by the Reporting Persons to report that, as of the date hereof, Abengoa has delivered an aggregate of 5,873,470 Ordinary Shares to certain holders of the 5.125% Exchangeable Notes due 2017 (the “Exchangeable Notes”) that have exchanged their Exchangeable Notes pursuant to the terms of the fiscal agency agreement dated March 5, 2015 between Abengoa and Citibank N.A., London Branch (the “Exchangeable Settlement”). As of the date of this Amendment No. 5, Abengoa expects to deliver an additional 407,649 Ordinary Shares on the applicable settlement dates to certain holders of the Exchangeable Notes that have delivered a notice to exchange.

Item 5. Interest in Securities of the Issuer.

As a result of the Exchangeable Settlement, Item 5 of the Schedule 13D is hereby amended and restated as follows:

(a) As of December 14, 2015, ACI is the direct beneficial owner of 43,279,832 Ordinary Shares and the Reporting Persons beneficially own 43.19% of the Ordinary Shares.

The following persons listed on Schedule A beneficially own the number of Ordinary Shares of the Issuer indicated: Ricardo Hausmann (280 Ordinary Shares), Jesus Garcia Quilez (3,900 Ordinary Shares) and Alfonso González Domińguez (4,690 Ordinary Shares).

(c) Except for the Exchangeable Settlement, no Reporting Person has effected any transactions in the Ordinary Shares during the past sixty days. To the knowledge of the Reporting Persons, none of the directors and officers of the Reporting Persons listed in Schedule A to this Schedule 13D effected any transactions in the Ordinary Shares during the past sixty days.

(d) Other than the Reporting Persons, no person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Reporting Persons’ securities.

(e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

Item 6 of the Schedule 13D is hereby amended by replacing the paragraphs under the headings “Exchangeable Notes” and “Margin Loan Facility Agreement” with the following:

Exchangeable Notes

On February 26, 2015, Abengoa sold an aggregate of $279,000,000 principal amount of 5.125% Exchangeable Notes due 2017 (the “Exchangeable Notes”). The Exchangeable Notes are exchangeable, at the option of the holders of the Exchangeable Notes, for Ordinary Shares that are beneficially owned by the Reporting Persons. The Exchangeable Notes were issued by Abengoa pursuant to a fiscal agency agreement dated March 5, 2015 between Abengoa and Citibank N.A., London Branch (the “Fiscal Agency Agreement”). As of the date hereof, Abengoa has delivered an aggregate of 5,873,470 Ordinary Shares to holders that exercised their option to exchange Exchangeable Notes and Abengoa expects to deliver an additional 407,649 Ordinary Shares on the applicable settlement dates to certain holders of the Exchangeable Notes that have delivered a notice to exchange. As of December 14, 2015, there were 1,201,559.74 Ordinary Shares subject to delivery to holders of the Exchangeable Notes upon exchange of the outstanding Exchangeable Notes.

Secured Term Facility Agreement

On October 22, 2015, ACI entered into a Secured Term Facility Agreement (the “Facility Agreement”) with Talos Capital Limited (the “Lender”), pursuant to which it is required to enter into related security documents (collectively, the “Loan Documents”). ACI is entitled to borrow up to $130,000,000 (the “Loan Amount”) under the Facility Agreement. Under the terms of the Loan Documents, ACI has pledged and granted a security interest in 14,000,000 Ordinary Shares of the Issuer (the “Pledged Shares”), in favor of the Lender as security for the Loan Amount and its obligations under the Loan Documents. The loan will mature 24 months following the date of the Facility Agreement, but upon the exercise of certain events that are customary for this type of loan, the Lender may exercise its right to require ACI to repay all or part of the Loan Amount, post additional collateral or foreclose on, and dispose of, the Pledged Shares in accordance with the Loan Documents.
