SCHEDULE 13D

Page 5 of 6 Pages

This Amendment No. 4 amends the Schedule 13D initially filed jointly with the Securities and Exchange Commission (“SEC”) by ENERGY HOLDING CORPORATION (“EHC”), Joaquin Fernandez and Alberto Velilla Becerra (collectively, the “Reporting Persons”) on April 28, 2014 with respect to ownership of the ordinary shares, par value $0.0001 per share (“Ordinary Shares”), of Tecnoglass Inc., a Cayman Islands exempted company (the “Issuer”), as previously amended by Amendment No. 1 thereto (“Amendment No. 1”) filed with the SEC by the Reporting Persons on June 12, 2015, Amendment No. 2 thereto (“Amendment No. 2”) filed with the SEC by the Reporting Persons on January 13, 2017 and Amendment No. 3 thereto (“Amendment No. 3”) filed with the SEC by the Reporting Persons on May 26, 2023 (as previously amended, the “Existing Schedule 13D,” and as amended hereby, this “Schedule 13D”). Except as set forth below, the disclosure in the Existing Schedule 13D remains unchanged. Capitalized terms used herein which are not defined herein have the meaning given to them in the Existing Schedule 13D.

The percentage of beneficial ownership reflected in this Schedule 13D is based upon 46,996,708 Ordinary Shares outstanding as of May 1, 2024 as reported by the Issuer in its Form 10-Q filed with the SEC on May 9, 2024.

Item 4. Purpose of Transaction.

Item 4 of the Existing Schedule 13D is hereby amended and restated to read in its entirety as follows:

The Issuer’s predecessor operating companies, Tecnoglass S.A. (“Tecnoglass”) and C.I. Energía Solar S.A. E.S. Windows (“ES”), were founded by José M. Daes, the Issuer’s Chief Executive Officer, and his brother Christian T. Daes, the Issuer’s Chief Operating Officer. José M. Daes, Christian T. Daes and members of their family indirectly own EHC, one of the Reporting Persons.

The Issuer was formed under the name “Andina Acquisition Corporation” as an exempted company in the Cayman Islands on September 21, 2011 in order to effect a merger, share exchange, asset acquisition, share purchase, recapitalization, reorganization or other similar business combination with one or more businesses or entities. On August 17, 2013, the Issuer entered into an Agreement and Plan of Reorganization (as amended, the “Merger Agreement”), with Tecno Corporation, Tecnoglass, ES and Andina Merger Sub, Inc. After signing the Merger Agreement, Tecnoglass and ES underwent a reorganization, in which (a) the holders of Tecnoglass and ES securities became the sole shareholders of EHC, (b) EHC became the sole shareholder of Tecno Corporation and (c) Tecnoglass and ES became the indirect, wholly-owned subsidiaries of Tecno Corporation. On December 20, 2013, the Issuer consummated the transaction contemplated by the Merger Agreement, whereby (i) a wholly-owned subsidiary of the Issuer merged with and into Tecno Corporation, with Tecno Corporation surviving as the wholly-owned subsidiary of the Issuer, and (ii) EHC received ordinary shares of the Issuer.

Each of the Reporting Persons may from time to time acquire securities of the Issuer for investment purposes, or dispose of securities of the Issuer, in the open market or in private transactions, including without limitation, sales pursuant to the exercise of the registration rights provided by the Amended and Restated Registration Rights Agreement dated December 20, 2013.

The Reporting Persons are currently evaluating, and from time to time in the future may evaluate, various alternatives for their investment in the Ordinary Shares. These alternatives may include, without limitation, a merger, sale or other business combination involving the Issuer (including transactions in which the Reporting Persons participate as buyers or co-investors); forming partnerships or joint ventures related to the Issuer and its shares; a recapitalization or reorganization of the Issuer; a sale or transfer of a material amount of assets of the Issuer; and selling Ordinary Shares to a third party. In connection with the evaluation of any such transaction, the Reporting Persons may engage in discussions with the Issuer’s management, board of directors, advisors, and third parties.

The Reporting Persons reserve the right to change their purpose and to formulate and implement plans or proposals with respect to the Issuer at any time and from time to time.
