• $0.20 per share cash dividend for first quarter to be paid mid-May

• Quarterly dividend projected to increase to $0.50 per share or more with IMTT payments

• Proportionately combined free cash flow per share increases 9%

NEW YORK--(BUSINESS WIRE)-- Macquarie Infrastructure Company LLC (NYSE: MIC) reported financial results for the first quarter of 2012 including proportionately combined free cash flow of $0.88 per share compared with $0.81 per share in the first quarter of 2011. The 9% increase reflects improved performance at each of MIC's four operating entities.

The Company also reported that its Board of Directors approved the distribution of a cash dividend of $0.20 per share for the first quarter. The cash dividend will be payable on May 17, 2012 to shareholders of record on May 14, 2012.

Proportionately combined free cash flow increased to $40.7 million in the first quarter of 2012 from $37.0 million in the first quarter of 2011. The aggregate increase reflects growth in free cash flow generated of:

• 66.0% at District Energy, the Company's 50.01% interest in a district cooling business in Chicago;
• 57.9% at The Gas Company, MIC's gas processing and distribution business in Hawaii;
• 16.4% at Atlantic Aviation, the Company's airport services business based in Plano, Texas; and,
• 11.0% at International-Matex Tank Terminals (IMTT), MIC's 50% equity investment in a bulk liquid storage terminal business headquartered in New Orleans, Louisiana.

MIC regards free cash flow as an important tool in assessing the performance of its capital intensive, cash generative businesses. The Company defines free cash flow as cash from operating activities, less maintenance capital expenditures and changes in working capital. Working capital movements are excluded on the basis that these are largely timing differences in payables and receivables, and are therefore not reflective of MIC's ability to generate cash. Proportionately combined free cash flow refers to the sum of the free cash flow generated by MIC's businesses and investments in proportion to its equity interest in each and after holding company costs. See "Cash Generation" below for further information.

"The first quarter was good for each of our operating entities," said James Hooke, Chief Executive Officer of Macquarie Infrastructure Company. "While we incurred significant legal expenses in the first quarter related to the IMTT arbitration, our continued active management helped our businesses perform well and at levels consistent with our guidance for the full year."

Excluding the effect of the expenses incurred in connection with the arbitration, MIC's proportionately combined free cash flow per share would have increased by 17.3% to $0.95 in the first quarter of 2012 from $0.81 in the first quarter of 2011.

Dividend Policy

In determining the MIC dividend for the first quarter of 2012, MIC's Board was not able to consider either the arbitration award or the dividend it believes IMTT should pay to each of its shareholders for the first quarter. Neither the payment due in settlement of the arbitration nor the cash flows generated by IMTT in the first quarter were distributed to MIC. MIC believes that the receipt of these funds and those that may become due in the future will result in its Board authorizing an increase in the amount of the Company's quarterly cash dividend.

Reflecting confidence in the Company's ability to secure the proceeds awarded in the arbitration, the MIC Board has expressed its intent to raise the MIC dividend to at least $0.50 per share, per quarter, following receipt of the award proceeds. The precise timing and amount of any future dividend, including an increase resulting from the receipt of the arbitration award proceeds, will be based on the continued stable performance of the Company's businesses and the economic conditions prevailing at the time of any authorization. Future dividends will also be dependent on compliance by MIC's co-investor with the dividend provisions of the IMTT Shareholders' Agreement.

The MIC Board's intent also reflects its past practice of paying substantially all of the cash generated by the Company's operating businesses to shareholders in the form of a quarterly cash dividend.

Arbitration Update

MIC reported on April 1, 2012 that it had been awarded $110.6 million at the conclusion of its arbitration with its co-investor in IMTT. The award represents the amount of dividends to which MIC was entitled through December 31, 2011 under the Shareholders' Agreement with its co-investor. The arbitration award also dismissed all of the co-investor's counterclaims, provided clarification as to the methodology used to calculate future dividends and directed the parties to comply with certain corporate governance recommendations.

On April 1, 2012 MIC filed a complaint in Delaware state court seeking confirmation of the award. MIC's co-investor has not challenged the confirmation proceedings, but has until May 24, 2012 to answer the complaint and until the end of June to move to vacate the award. If the award is confirmed in Delaware state court, MIC will then be able to seek enforcement of the judgment through separate court proceedings. Those proceedings could take six months or longer to complete.

MIC continues to work with its co-investor on the implementation of the award and payment of all dividends due under that decision. Consistent with the performance of the business in the first quarter and the interpretation of the Shareholders' Agreement ordered in the arbitration, MIC proposed a dividend for the first quarter of 2012 of $22.6 million per shareholder.

"We are pleased to have concluded the arbitration with our co-investor in IMTT, although we're disappointed not to have received the award proceeds or a dividend for the first quarter as yet," Hooke noted. "Our co-investor's representatives have said that they plan to comply with the terms of the award. They have proposed a dividend for the first quarter that, while less than the award requires, does represent a step forward by them. We remain hopeful that our co-investor will comply with the award of past and payment of current dividends soon."

Consolidated Results for First Quarter

MIC's consolidated revenue for the first quarter of 2012 increased 10.4% compared with the first quarter of 2011 to $264.9 million. The growth in revenue reflects both higher energy costs, such as the cost of jet fuel and synthetic natural gas that are passed through to customers of MIC's businesses, and an increase in the volume of product sold.

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 $100.6 million in the first quarter of 2012, an increase of 5.4% over the same period in 2011.

MIC reported $20.7 million of net income, before taxes, in the first quarter of 2012 compared with net income of $17.8 million in the first quarter of 2011.

Cash Generation

MIC reports EBITDA excluding non-cash items on a consolidated and operating segment basis and reconciles each to consolidated net income. EBITDA excluding non-cash items is a measure relied upon by management in evaluating the performance of its businesses and investments. EBITDA excluding non-cash items is defined as earnings before interest, taxes, depreciation and amortization and non-cash items, which include impairments, gains and losses on derivatives and adjustments for certain other items reflected in the statement of operations.

MIC believes that EBITDA excluding non-cash items provides additional insight into the performance of its operating businesses, relative to each other and to similar businesses, without regard to capital structure, and their ability to service or reduce debt, fund capital expenditures and/or support distributions to the holding company.

MIC also reports free cash flow, as defined below, on both a consolidated and operating segment basis as a means of assessing the amount of cash generated by its businesses and as a supplement to other information provided in accordance with GAAP, and reconciles each to cash from operating activities. MIC believes that reporting free cash flow provides additional insight into its ability to deploy cash, as GAAP measures, such as net income and cash from operating activities, do not reflect all of the items that management considers in estimating the amount of cash generated by its operating businesses.

MIC defines free cash flow as cash from operating activities, less maintenance capital expenditures and changes in working capital. Working capital movements are excluded on the basis that these are largely timing differences in payables and receivables, and are therefore not reflective of MIC's ability to generate cash.

MIC notes that free cash flow does not fully reflect its ability to freely deploy generated cash, as it does not reflect required principal payments on indebtedness, payments of dividends, potential growth capital expenditures and other fixed obligations or the other cash items excluded when calculating free cash flow. Free cash flow may be calculated differently by other companies which limits its usefulness as a comparative measure. Free cash flow, as defined by MIC, should be used as a supplemental measure and not in lieu of financial results reported under GAAP.

(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.

IMTT

MIC has a 50% equity interest in IMTT, the operator of one of the largest independent bulk liquid storage terminal businesses in the U.S. IMTT owns and operates 10 marine storage terminals in the U.S. 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 5.3% during the first quarter compared with the first quarter of 2011 primarily as a result of the improvement in average storage rental rates. Average storage rental rates increased 5.6% in 2012. With a small number of expected 2012 contract renewals having been completed, MIC now expects average storage rates to increase in a range between 5.5% and 7.5% for the full year.

Capacity utilization increased to 95.9% from 93.8% during the first quarter of 2012 compared with the first quarter of 2011. Utilization rates improved as tanks that had been out of service for cleaning and inspection were returned to service in the first quarter. MIC expects utilization rates for the full year to be comparable with those achieved in 2011.

Environmental response gross profit generated in the quarter of 2012 increased to $1.2 million from less than $100,000 in the first quarter of 2011. There was a modest increase in the amount of spill response activity in which IMTT's environmental response subsidiary was involved in 2012.

IMTT's quarterly free cash flow increased to $31.5 million in the first quarter of 2012 from $28.4 million in 2011 due to the improvement in operating results.

The Gas Company

The Gas Company is the owner and operator of the only regulated ("utility") gas processing and pipeline distribution network in the Hawaiian Islands. The business is also the owner and operator of the largest unregulated ("non-utility") propane gas distribution business on the islands.

Non-utility contribution margin increased 42.2% during the first quarter of 2012 compared with the first quarter in 2011. The increase reflects both a 6.7% increase in the volume of gas sold and effective margin management during a period in which wholesale propane prices fluctuated by more than 10%. Utility contribution margin decreased slightly versus the prior comparable period.

The Gas Company generated $8.0 million of free cash flow in the first quarter of 2012. Free cash flow increased by $2.9 million compared with the first quarter of 2011 primarily as a result of the improved operating results of the non-utility portion of the business and a decrease 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 increased 30.3% at District Energy in the first quarter of 2012 compared with the first quarter of 2011. The increase was primarily due to improved performance related to the warmer than average temperatures in Chicago this year versus the first quarter of 2011 that drove increased demand for cooling. The business also recorded lower expenditures for preseason system maintenance. A higher percentage of total preseason maintenance was conducted in the first quarter of 2011 compared with 2012.

Free cash flow increased 66.0% to $2.7 million in the first quarter of 2012 compared with the first quarter of 2011 primarily due to the improved operating performance.

Atlantic Aviation

Atlantic Aviation owns and operates a network of fixed-base operations (FBO) that primarily provide fuel, terminal services and aircraft hangar services to owners and operators of general aviation (GA) aircraft at 65 airports in the US. The network is the largest of its type in the U.S. air transportation industry.

Gross profit for the first quarter of 2012 increased 1.4% compared with the first quarter of 2011 primarily as a result of an increase in the volume of GA jet fuel sold and the margin achieved on those sales. The same store volume of GA jet fuel sold increased 1.4% while margins were up 3.3%.

Same store gross profit increased 2.1% in the first quarter including a sharp drop in revenue and gross profit generated from de-icing activity in the first quarter of 2012 compared with the first quarter of 2011. Excluding the impact of de-icing in both periods, same store gross profit would have increased by 3.9%.

Selling, general and administrative (SG&A) were lower in the first quarter of 2012 compared with the first quarter of 2011 as a result of lower lease costs reflecting sales of several FBOs last year. Property and casualty insurance expenses declined as well, helped by Atlantic Aviation's track record of safety and effective insurance procurement practices.

Free cash flow generated by Atlantic Aviation during the first quarter of 2012 increased 16.4% to $19.1 million from $16.4 million in the first quarter of 2011.

Business Outlook

Management at MIC has provided the following update to previously provided guidance regarding the performance of the Company's operating businesses in 2012.

IMTT — MIC continues to expect the business will generate between $220.0 and $235.0 million of EBITDA excluding non-cash items during 2012. Maintenance capital expenditures were seasonally normal during the first quarter and are expected to be approximately $50.0 to $55.0 million for the full year. If growth capital assets are placed in service as planned during the year, IMTT is likely to have little or no current federal income tax liability as a result of depreciation (non-cash) expenses associated with these expenditures.

The Gas Company — the business is expected to generate between $50.0 and $55.0 million of EBITDA excluding non-cash items in 2012. Maintenance capital expenditures are anticipated be approximately $6.7 million for the full year or down by about one third on 2011. Strong performance in the first quarter, particularly from the non-utility portion of the business suggests that The Gas Company is likely to finish 2012 at the higher end of the range of EBITDA guidance.

District Energy — the business is expected to generate between $21.0 and $22.0 million of EBITDA excluding non-cash items. Maintenance capital expenditures are expected to be approximately $1.0 million for the full year. The relatively strong performance of the business in the first quarter suggests a full-year result at the higher end of guidance assuming peak cooling season temperatures are consistent with historical norms.

Atlantic Aviation — the business is expected to generate between $130.0 and $140.0 million of EBITDA excluding non-cash items during 2012. Maintenance capital expenditures are expected to be approximately $13.1 million for the full year. The level of performance improvement in the first quarter was consistent with a full-year result in the range of current guidance.

MIC management believes that the forecast results of the Company's operating businesses, combined with the expenses of the holding company produce an aggregate range of proportionately combined free cash flow of between $3.50 and $3.60 per share for 2012.
