On May 15, 2015, Macquarie Infrastructure Company LLC (the “Company”) held a special meeting of its shareholders (the “Special Meeting”) to consider and vote on a proposal to approve a plan of conversion, including the certificate of incorporation and bylaws contemplated thereby (collectively, the “Plan of Conversion”), dated as of April 10, 2015, providing for the conversion of the Company from a limited liability company organized under the laws of the State of Delaware to Macquarie Infrastructure Corporation, a corporation organized under the laws of the State of Delaware (the “Conversion Proposal”) and a proposal to approve the authorization of 100,000,000 shares of preferred stock, par value $0.001 per share, and the related provisions in the proposed certificate of incorporation, conditioned on consummation of the Plan of Conversion (the “Preferred Stock Proposal”). As the Conversion Proposal and the Preferred Stock Proposal were approved at the Special Meeting, the proposal to adjourn the Special Meeting to a later date or dates to solicit additional proxies was unnecessary and was not submitted to the Company’s shareholders for approval at the Special Meeting. The Conversion Proposal and the Preferred Stock Proposal are described in detail in the Company’s Definitive Proxy Statement on Schedule 14A filed with the Securities and Exchange Commission on April 17, 2015.

The matters voted upon and the results of the vote at the Special Meeting were as follows:

Proposal 1 – Approve a plan of conversion: The Company’s shareholders approved the Conversion Proposal with the votes shown:

Proposal 2 – Approve the authorization of preferred stock: The Company’s shareholders approved the Preferred Stock Proposal with the votes shown:

On May 15, 2015, the Company issued a press release announcing the results of the shareholder votes at the Special Meeting, a copy of which is attached hereto as Exhibit 99.1 and incorporated herein by reference.
