NEW YORK -- July 5, 2013

Macquarie Infrastructure Company (NYSE: MIC) announced that its management
company, Macquarie Infrastructure Management (USA) Inc. (“MIMUSA”), has earned
a performance fee of $24.4 million for the second quarter of 2013.

The performance fee for the second quarter reflects an average closing value
of the MIC accumulation index for the last 15 trading days of the quarter that
was 4.3% above the average closing of the accumulation index for the 15
trading days ended March 28, 2013.

Based on the Management Services Agreement (“MSA”) between MIC and MIMUSA, the
management company is entitled to a performance fee equal to 20% of the value
of MIC’s total return in excess of its utility index benchmark. The fee is
subject to MIC’s total return being positive and in excess of any prior
underperformance.

MIMUSA is expected to reinvest the second quarter performance fee in
additional shares of MIC. Any performance fees generated previously have also
been reinvested in additional shares. In accordance with the MSA, the price at
which additional shares would be issued to MIMUSA will be calculated using the
volume weighted average price of MIC’s shares over a 15-day period following
the release of the Company’s financial results for the second quarter of 2013.
