MACQUARIE INFRASTRUCTURE COMPANY REPORTS                        (MACQUARIE LOGO)

SECOND QUARTER 2006 FINANCIAL RESULTS

DISTRIBUTION INCREASE OF 5%, ANNUALIZED, ANNOUNCED

NEW YORK, NY - AUGUST 9, 2006 - Macquarie Infrastructure Company (NYSE: MIC)
reported consolidated revenue of $105.9 million for the quarter ended June 30,
2006, an increase of 46% over the second quarter in 2005. Operating income for
the period totalled $13.6 million, an 81% increase over the June quarter in
2005. The increases were the result of solid organic growth in key businesses
and strong contributions from acquisitions made in new and existing sectors of
infrastructure.

On August 7, 2006, the MIC Board authorized an increase in the quarterly
distribution to shareholders of 5%, annualized, based on the expected
continuation of strong performance by the Company's operating businesses and
investments. An increased distribution of $0.525 per share will be payable on
September 11, to shareholders of record on September 6. Shares of trust stock
will trade ex-distribution on September 1, 2006.

For the six months ended June 30, 2006, MIC generated estimated cash available
for distribution to trust shareholders of $1.15 per share. Estimated cash
available for distribution includes cash from operations (a GAAP metric) plus
items that do not flow through the Company's income statement, such as dividends
from its investments, plus adjustments for the timing of certain expenses
including maintenance capital expenditures and management fees. Estimated cash
available for distribution increased 29% over the first six months of 2005.

"Our ability to increase our distribution for the second quarter reflects the
strong cash generating capacity of our initial businesses and a solid measure of
additional cash flow from our recent acquisitions," said Peter Stokes, Macquarie
Infrastructure Company Chief Executive Officer. "Our performance year to date,
together with our recent acquisitions, gives us considerable confidence that our
cash available for distribution will exceed our actual distributions from this
point forward."

Cash from operations in the first half of 2006 totalled $23.4 million, up 13%
over the first half of 2005.

Earnings before interest, taxes, depreciation and amortization ("EBITDA") grew
to $26.9 million in the second quarter of 2006, a 41% increase over the second
quarter of 2005. For a reconciliation of net income to EBITDA, please see the
last page of this release.

For the quarter, MIC reported net income of $4.5 million or $0.17 per share.

          respectively, taking into account recent acquisitions. The district
          energy business made no acquisitions during the prior year.

     -    Consolidated gross profit increased 42% and 34% over the prior
          comparable quarter and six months, respectively, on improved
          performance by the Company's airport services and airport parking
          businesses.

     -    MIC successfully completed acquisitions of 50% of the holding company
          of International- Matex Tank Terminals - a bulk liquid storage
          terminal business, and 100% of The Gas Company in Hawaii - a gas
          production and distribution company. Following the close of the
          quarter, the Company also completed the acquisition of 100% of the
          stock of Trajen Holdings, Inc. - a network of 23 fixed base operations
          that is being integrated into the Company's airport services business,
          Atlantic Aviation.

DISTRIBUTIONS

On August 7, 2006, the Company's Board of Directors declared a distribution to
shareholders for the quarter ended June 30, 2006 of $0.525 per share. Shares of
trust stock will trade ex-distribution on September 1, 2005. The distribution
will be payable on September 11, 2006 to shareholders of record at the close of
business on September 6, 2006.

The Company intends to declare and pay regular quarterly cash distributions on
all outstanding shares. The Company anticipates declaring and paying a quarterly
distribution for the quarter ending September 30, 2006 of $0.525 per share.

The Company's distribution policy is based on the predictable and stable cash
flows of its businesses and investments. The Company's intention is to
distribute to its shareholders the majority of its cash available for
distribution and not to retain significant cash balances in excess of prudent
reserves.

BUSINESS UPDATE

On May 7, 2006, MIC completed its acquisition of shares representing 50% of IMTT
Holdings, the parent company of International-Matex Tank Terminals. IMTT is the
owner/operator of 8 bulk liquid storage terminals in the U.S. and part owner and
operator of 2 terminals in Canada.

MIC invested $257 million in IMTT of which approximately $145 million will be
invested in the development of new bulk liquid storage capacity and facilities.
The new capacity of approximately 1.2 million barrels of petroleum, vegetable
and animal oil storage, and 570 thousand barrels of storage capacity, blending
and packaging operations at a chemical logistics facility, will be located at or
near IMTT's existing operations in Louisiana.

MIC entered into a shareholders' agreement that provides for the payment of a
quarterly dividend from IMTT of $7 million through the 4th quarter of 2007. MIC
received the first such dividend for the second quarter of 2006 on July 26th.
The investment in IMTT will be accounted for under the equity method. As such,
MIC will record its share of IMTT's net income as equity in earnings of
investees (reversed in cash from operations) and the dividend will be recorded
as a receivable on the MIC balance sheet at quarter end.

On June 7, 2006, MIC completed its purchase of The Gas Company in Hawaii. The
Gas Company is the sole utility provider of synthetic natural gas and liquid
petroleum gas on the islands of Hawaii. The company also operates an unregulated
business that is the largest distributor of propane in Hawaii.

MIC financed the purchase and associated transaction costs totalling $272
million with subsidiary level debt of $160 million, a drawing on its revolving
acquisition facility of $99 million and the balance in cash. The Gas Company's
consolidated results are included in MIC's results for the 24 days from the
closing date of the transaction through the end of the period.

On July 11, 2006, MIC completed its acquisition of Trajen Holdings, Inc., a
network of 23 fixed base operations in 11 states. The Trajen operations are
being combined beneath MIC's Atlantic Aviation brand in its airport services
business to form the second largest network of fixed base operations in the
industry.

The $363 million acquisition Trajen (including transaction costs, and pre-funded
integration and capital expenditures) was financed with a combination of an
increase in the Company's airport services business credit facility of $180
million, an acquisition related term loan at the MIC level of $180 million and
the balance in cash. Results for Trajen will be reported as a component of MIC's
airport services segment beginning with the third quarter of 2006.

On August 8, 2006, the Company, through its airport parking subsidiary, received
a commitment letter from Capmark Finance, Inc. for the refinancing of $184.2
million of floating rate loans of the airport parking business. The commitment
provides for an increase in the debt to $195.0 million at a floating rate based
on the one month LIBOR

<PAGE>

rate, plus a margin of 1.90% (down from a weighted average of 3.22%). The loan
has a three year term and the Company intends to hedge 100% of its floating rate
exposure through a swap or rate cap structure.

ESTIMATED CASH AVAILABLE FOR DISTRIBUTION

The Company believes that GAAP measures, including certain adjustments to GAAP
measures, provides better insight into the performance of its operating
businesses and its ability to service its obligations and support its ongoing
distribution policy. In particular, GAAP results alone do not reflect other cash
items that management considers in estimating cash available for distribution.

The table below summarizes year-to-date cash receipts and payments that are not
reflected on the Company's income statement in order to provide additional
insight into management's estimate of cash available for distribution. The
Company believes that cash generated by its businesses and investments will be
sufficient to meet its indicated distributions in 2006.

For the first half of 2006 the Company's businesses generated $23.4 million, or
$0.86 per share, in cash from operations. The contribution from the gas utility
business, The Gas Company, reflects MIC's 24 days of ownership of that business.
Adjusting for timing of certain receipts and payments, MIC estimates year to
date cash available for distribution to be $31.2 million, or $1.15 per share.
This represents a 29% increase over the $0.89 of cash available for distribution
from the Company in the first half of 2005.

receivable at June 26 and received the cash dividend on July 26.

BUSINESS/SEGMENT HIGHLIGHTS FOR THE QUARTER ENDED JUNE 30, 2006

The following is a segment analysis of results from operations for the quarter
and year to date periods ended June 30, 2006, compared to results for the
quarter and year to date periods ended June 30, 2005.

The Company has included EBITDA, a non-GAAP financial measure, on both a
consolidated basis as well as for each of its segments as it considers it to be
an important measure of its overall performance. The Company believes EBITDA
provides additional insight into the performance of its operating companies and
its ability to service its debt and support its ongoing distribution policy.

KEY FACTORS

     -    Contribution of positive operating results from one FBO in Las Vegas

     -    Existing locations had higher average dollar per gallon fuel margins
          and unchanged fuel volumes

     -    Higher selling, general and administrative costs primarily relating to
          non-cash and accrued compensation expense in 1Q'06 and increased
          credit card fees based on higher revenues

     -    Higher interest costs from higher debt levels resulting from the
          refinancing in December 2005 - the majority of the $100 million of
          proceeds was invested in IMTT in May 2006

KEY FACTORS

     -    Capacity revenue increased generally in-line with inflation

     -    Pre-season maintenance expenses for system reliability incurred
          earlier compared to the prior year

     -    Scheduled increases in contract consumption rates (in accordance with
          the terms of existing customer contracts) increased revenue and offset
          lower ton-hour sales resulting from cooler weather in 2006 versus 2005
