NEW YORK -- April 8, 2013

Macquarie Infrastructure Company (NYSE: MIC) announced that it has filed an
automatic shelf registration statement on Form S-3 (“shelf”) with the
Securities and Exchange Commission.

Along with the shelf registration statement the Company has filed a prospectus
supplement with respect to a previously announced dividend reinvestment/direct
stock purchase program named MIC Direct. The prospectus supplement relates to
the issuance of up to 1 million additional shares of MIC to participants in
MIC Direct. The Company may also choose to fill requests for reinvestment of
dividends or share purchases through MIC Direct via the open market.

Investors interested in participating in MIC Direct may contact the plan
administrator, Computershare Trust Company, N.A.("Computershare"), at
866-867-6422 or on-line at www.computershare.com/investor for a copy of the
prospectus and the prospectus supplement as well as application forms.

The filing of the shelf registration of Form S-3 allows the Company to issue
and sell an indeterminate amount of its LLC interests and debt securities in
one or more future offerings. The specific terms of any future offering will
be established by the Company at the time of the offering, subject to market
conditions, and will be described in a prospectus supplement filed at the time
of such offering.

This press release shall not constitute an offer to sell or the solicitation
of an offer to buy any securities. Any offer of securities will be made solely
by means of the prospectus included in the registration statement and any
applicable prospectus supplement that may be issued with respect to any
offering.

MIC also announced that it intends to release its financial results for the
first quarter of 2013 after the close of market trading on Monday, April 29,
2013. The Company has scheduled a conference call and webcast for analysts and
investors at 8:00 a.m. Eastern Time on Tuesday, April 30, 2013 during which
management will discuss the quarterly results.

conference call on the company’s website at www.macquarie.com/mic.

meeting have been updated from those published by MIC in its annual report on
