13D

Item 1. Security and Issuer.

This Amendment No. 2 (“Amendment No. 2”) amends and supplements the Schedule 13D filed by The Hydrogen Company and L’Air Liquide S.A. (the “Reporting Persons”) on January 31, 2019 (“13D”) and Amendment No. 1 to the 13D filed with the SEC on June 28, 2019 (“Amendment No. 1”), and relates to the Common Shares, no par value (“Shares”), of Hydrogenics Corporation, a corporation organized under the laws of Canada (the “Issuer”).

On September 9, 2019, the Reporting Persons and the Issuer completed the previously disclosed and court-approved plan of arrangement under the provisions of Section 192 of the Canada Business Corporations Act. As a result, Atlantis AcquisitionCo Canada Corporation (“Atlantis”), a subsidiary of Cummins Inc., acquired all of the outstanding Shares of the Issuer, and the Reporting Persons contributed all of the 3,537,931 Shares previously held by The Hydrogen Company in exchange for common shares of Atlantis, on a one-for-one basis.

This Amendment No. 2 is being filed to report the disposition of all of the Shares beneficially owned by the Reporting Persons as a result of consummation of the plan of arrangement, although, as previously reported, the Shares are in the process of being delisted from the Toronto Stock Exchange and the Nasdaq Global Market and being deregistered with the Ontario Securities Commission and the U.S. Securities and Exchange Commission.
