Macquarie Infrastructure Company LLC Reports First Quarter 2011 Financial Results, Reinstates Dividend

• Dividend of $0.20 per share in cash to be paid mid-May

• Operating results reflect continued strength across portfolio businesses

• Proportionately combined free cash flow increases

NEW YORK--(BUSINESS WIRE)--May 4, 2011--Macquarie Infrastructure Company LLC (NYSE: MIC) reported financial results for the first quarter of 2011 including year on year growth in proportionately combined free cash flow and reinstatement of a cash dividend. The MIC Board approved the distribution of a dividend of $0.20 per share for the first quarter to shareholders of record on May 11, 2011.

Proportionately combined free cash flow increased to $37.0 million in the first quarter of 2011 from $36.7 million in the first quarter of 2010. The overall increase in 2011 reflects a 22.7% increase in free cash flow from Atlantic Aviation offset by a reduced contribution from International-Matex Tank Terminals (IMTT) and The Gas Company compared with 2010. At both IMTT and The Gas Company, improved operating performance was offset by higher taxes and previously foreshadowed increases in maintenance capital expenditures.

MIC regards free cash flow as an important tool in assessing the performance of its capital intensive, cash generative businesses. MIC defines free cash flow as cash from operating activities, less maintenance capital expenditures and changes in working capital.

“We are pleased with our ability to reinstate a cash dividend,” said James Hooke, chief executive officer of Macquarie Infrastructure Company. “All of our businesses continued to perform well and in line with our expectations, notwithstanding a negative impact on our airport services business from the harsh winter weather. Their performance gives us confidence that we have reinstated a sustainable and potentially growing quarterly dividend.”

MIC’s consolidated revenue increased 19.2% compared with the first quarter in 2010 to $239.9 million in 2011. The growth in revenue primarily reflects higher energy costs, such as aviation fuel and gas products that are passed through to customers of MIC’s businesses.

Reported gross profit – defined as revenue less cost of goods sold – removes the volatility in revenue associated with fluctuations in energy costs. MIC’s consolidated gross profit totaled $95.5 million in the first quarter of 2011, an increase of 4.1% over the same period in 2010.

MIC reported net income from continuing operations, before tax, of $17.8 million compared with a net loss of $6.6 million in 2010.

Cash Generation

The following table reflects results of continuing operations for MIC’s businesses for the quarters ended March 31, 2011 and 2010 on a proportionately combined basis. Proportionately combined free cash flow includes the cash generated at MIC’s wholly-owned subsidiaries as well as its 50% interest in the free cash flow generated by IMTT and 50.01% interest in the free cash flow generated by District Energy, all offset by MIC corporate level expenses.

Proportionately combined free cash flow does not fully reflect MIC’s ability to freely deploy generated cash, as it does not reflect required principal payments on indebtedness and other fixed obligations, or dividends among other items. Free cash flow, as defined by MIC, should be used as a supplemental measure and not in lieu of financial results reported under GAAP. See the attached tables for a reconciliation of consolidated net income attributable to MIC LLC to consolidated EBITDA excluding non-cash items and cash from operating activities to free cash flow.

_____________________

(1) Proportionately combined free cash flow is equal to the sum of free cash flow attributable to MIC's ownership interest in each of its operating businesses and MIC Corporate.

A 32.8% increase in maintenance capital expenditures overall resulted from the Company’s efforts to take advantage of incentives authorized in the Tax Relief, Unemployment Insurance Reauthorization and Job Creation Act of 2010. “As previously disclosed, we expect to incur higher capital expenditures over the course of the year to take advantage of the tax benefits associated with 100% depreciation of these projects in 2011. Excluding the impact of the increased expenditures, proportionately combined free cash flow has continued to grow,” added Hooke.

IMTT

MIC has a 50% equity interest in IMTT, the operator of one of the largest independent bulk liquid storage terminal businesses in the US. IMTT owns and operates 10 marine storage terminals in the US and is the part owner and operator of two terminals in Canada. The terminals store and handle a wide variety of petroleum grades, chemicals and vegetable and animal oils. To aid in meaningful analysis of the performance of IMTT across periods, the table and discussion below refers to results for 100% of the business, not just MIC’s 50% interest.

Terminal revenue at IMTT grew 10.9% during the quarter compared with the first quarter of 2010 primarily as a result of improvement in average storage rental rates. Storage rental rates increased 13.3% during the first quarter of 2011 compared with the first quarter of 2010. IMTT expects full-year average storage rental rates to increase by approximately 11.0%.

As anticipated, capacity utilization decreased to 93.8% from 96.0% during the quarter compared with the first quarter of 2010. Utilization rates were lower primarily due to tank modifications for certain customers as well as tanks being taken out of service for inspection and repairs and maintenance. IMTT expects utilization rates to remain between 93.0% and 94.0% throughout 2011 while these projects are underway.

Environmental response gross profit for the quarter decreased to near zero from $3.3 million during the first quarter of 2010. Oil Mop, IMTT’s environmental services subsidiary, was involved in spill clean-up activity in early 2010 that did not recur in 2011.

IMTT’s free cash flow for the quarter declined to $28.4 million in 2011 from $33.5 million in 2010, primarily due to an increase in taxes payable.

MIC disclosed in mid-February that it had been unable to resolve a dispute with the co-owner of IMTT regarding distributions to each of the shareholders of IMTT. Ongoing efforts since that time have similarly failed to resolve the matter and on April 18, 2011, MIC initiated formal arbitration proceedings with the Voting Trust of IMTT Holdings Inc. and IMTT Holdings Inc. as provided for in the Shareholders’ Agreement between the parties.

The Gas Company

The Gas Company is the owner and operator of the only regulated (“utility”) gas manufacturing and pipeline distribution network on the islands of Hawaii. The business is also the owner and operator of the largest unregulated (“non-utility”) gas distribution operation on the islands.

Utility contribution margin increased 14.6% over the prior corresponding period to $10.3 million, primarily due to a correction to the calculation of pass-through of changes in feedstock costs (fuel adjustment charges) booked in the first quarter of 2010 related to the rate increase effective in mid-2009.

Non-utility contribution margin per thermal unit of gas was flat with the prior comparable period. Non-utility contribution margin decreased slightly primarily as a result of a 1.6% decrease in the volume of gas sold. The decrease in volume was the result of conservation efforts related to an interruption in supply.

The Gas Company generated $5.1 million of free cash flow in the first quarter of 2011. Free cash flow decreased by $1.6 million compared with 2010 primarily as a result of expected increases in maintenance capital expenditures.

District Energy

MIC’s District Energy business produces chilled water that it distributes via underground pipelines in downtown Chicago to high-rise buildings for use in air conditioning and process cooling systems. The business also operates a site-specific operation that supplies both cooling and heating services to three customers in Las Vegas, Nevada. MIC has a 50.01% (controlling) interest in District Energy.

Gross profit decreased slightly primarily due to the timing of preseason system maintenance expenditures and higher real estate taxes. A higher percentage of preseason maintenance was conducted in the first quarter of 2011 compared with 2010.

Free cash flow declined 18.8% to $1.6 million in the first quarter of 2011 compared with 2010 primarily due to increased selling, general and administrative expenses, cash interest, and taxes, partially offset by lower maintenance capital expenditures.

Atlantic Aviation

Atlantic Aviation owns and operates a network of fixed-base operations (FBO) that primarily provide fuel, terminal services and aircraft hanger services to owners and operators of general aviation (GA) aircraft at 66 airports and one heliport in the US. The network is the largest of its type in the US air transportation industry.

Gross profit for the first quarter of 2011 increased primarily as a result of a 1.7% increase in the volume of GA fuel sold, driven by increased flight movements and an increase in weighted average GA fuel margins of 3.8% compared with the first quarter of 2010.

General aviation traffic and fuel volumes at a number of airports served by Atlantic Aviation were reduced by bad weather in the first quarter of 2011. 22 FBOs were closed for an average of 3.5 day each during the first quarter. Atlantic management believes the weather related disruptions reduced total gross profit for the period by approximately $1.1 million.

Selling, general and administrative (SG&A) expenses increased 1.8% due to higher payroll taxes, weather-related expenses such as snow removal and motor fuel costs. Atlantic Aviation expects selling, general and administrative expense to be at or below the previously disclosed $175.0 million for 2011.

Free cash flow generated by Atlantic Aviation during the first quarter of 2011 increased 22.7% to $16.4 million from $13.4 million in the first quarter of 2010.
