Macquarie Infrastructure Company LLC Reports Third Quarter 2013 Financial Results, Declares Cash Dividend of $0.875 Per Share

• Reported proportionately combined Free Cash Flow increases 78%

• Free Cash Flow per share guidance of $4.10 to $4.20 in 2013 reaffirmed

• Strong performance by Atlantic Aviation, new FBO acquisition announced

• 41% increase in growth investments

NEW YORK--(BUSINESS WIRE)--October 28, 2013--Macquarie Infrastructure Company LLC (NYSE:MIC) reported its financial results for the third quarter of 2013 including the declaration of a quarterly cash dividend of $0.875 per share. The dividend will be paid on November 14, 2013 to shareholders of record on November 11, 2013.

MIC’s businesses generated proportionately combined Free Cash Flow of $57.0 million or $1.08 per share during the quarter, compared with $32.1 million or $0.69 per share in the comparable period in 2012. Excluding interest rate swap breakage costs incurred by MIC’s Hawaii Gas business in the third quarter of 2012, underlying proportionately combined Free Cash Flow increased 40.0% in the third quarter of 2013. Underlying proportionately combined Free Cash Flow per share increased 18.9% to $3.28 for the nine months ended September 30, 2013 compared with $2.76 for the nine months ended September 30, 2012.

MIC’s proportionately combined Free Cash Flow per share in 2013 reflects an approximate 6.4 million share (13.6%) increase in the weighted average number of shares outstanding. The increase is associated primarily with a public equity offering conducted by the Company in May 2013 as well as management and performance fees settled in shares during the past year.

“The performance of our businesses in the third quarter was largely in line with our expectations and positions us to deliver proportionately combined free cash flow for the full year that is consistent with our guidance and consistent with the generation of approximately $337.0 million in proportionately combined EBITDA,” said James Hooke, Chief Executive Officer of Macquarie Infrastructure Company LLC.

“We are reaffirming our guidance of $4.10 to $4.20 in proportionately combined Free Cash Flow for calendar year 2013. On a trailing twelve month basis, MIC has generated $4.09 per share in proportionately combined Free Cash Flow so we’re already within sight of our guidance range as we end the third quarter,” Hooke added.

Hooke noted that the improving outlook reflected better than anticipated pricing on a refinancing of the long-term debt of MIC’s Atlantic Aviation business in May as well as improvement in the operating performance of Atlantic Aviation generally. “With 13.0% EBITDA growth at Atlantic Aviation for the quarter, a substantial pipeline of new growth projects, and the addition of the Hangar 10 aviation services facility at Kansas City Downtown Airport to the Atlantic Aviation portfolio, the trends in the business have been positive over the past several quarters,” he said.

On October 25, 2013, MIC’s Atlantic Aviation business entered into an agreement to acquire Hangar 10 Aviation Services located on the Kansas City Downtown Airport. The award-winning facility is expected to become the 63rd facility in the Atlantic Aviation network. The acquisition is projected to close in November 2013, subject to receipt of required airport approvals and other consents customary for a transaction of this size and type.

MIC established a new line of business – MIC Solar - in the fourth quarter of 2012 with an investment in two contracted solar power generation facilities. In the third quarter of 2013 MIC invested $14.7 million in two additional facilities currently under construction. In October of 2013 the Company invested $6.1 million in a fifth facility that is also under construction. MIC has invested a total of $30.1 million in the five facilities. The Company anticipates that the facilities will generate a total of between $1.6 million and $1.8 million in Free Cash Flow in each of the next five years.

Located in the southwestern U.S., the Company’s photovoltaic facilities are capable of generating a combined approximately 57 megawatts of electricity. The electricity is sold to nearby utilities and a U.S. Air Force base pursuant to long-term (20 and 25 year) power purchase agreements.

Hooke noted, “Year to date through September, 2013, MIC has deployed $14.7 million in solar contracted power, and $58.6 million in other growth projects representing a 40.7% increase over the rate at which capital was put to work in the first nine months of 2012. Collectively our businesses have committed to another approximately $70.0 million of projects. In addition to this, we are also exploring a pipeline of opportunities in excess of $100.0 million.”

MIC regards Free Cash Flow as an important tool in assessing the performance of its capital intensive, cash generative businesses. 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 entity after holding company costs. See “Cash Generation” below for MIC’s definition of Free Cash Flow and further information.

Consolidated Results for Third Quarter and Nine Months

The Company reported net income, before tax, of $14.1 million for the third quarter of 2013 compared with a net loss of $1.9 million for the third quarter of 2012. For the nine months ended September 30, 2013, MIC reported net income, before tax, of $23.2 million compared with net income of $40.8 million for the comparable period in 2012. The decrease in the year to date result versus the prior comparable period is primarily attributable to performance fees incurred in 2013.

MIC’s consolidated revenue for the third quarter of 2013 increased 1.7% to $263.7 million compared with $259.3 million in the third quarter of 2012. Consolidated revenue was essentially flat for the nine-month period ended September 30, 2013 versus the comparable period in 2012.

Reported gross profit – defined as revenue less cost of goods sold – removes the volatility in revenue associated with fluctuations in energy costs such as feedstock costs at Hawaii Gas. MIC’s consolidated gross profit rose 6.4% to $108.0 million in the third quarter of 2013 from $101.5 million in the same period in 2012. For the nine months ended September 30, 2013 the Company’s gross profit increased 4.8% versus the comparable period in 2012.

Cash Generation

MIC reports EBITDA excluding non-cash items on a consolidated and operating segment basis and reconciles each to consolidated net income (loss). 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 may 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 where GAAP measures, such as net income (loss) 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.

Free Cash Flow does not fully reflect MIC’s ability to freely deploy generated cash, as it does not reflect required payments made on its indebtedness and other fixed obligations or the other cash items excluded when calculating Free Cash Flow. Free Cash Flow may be calculated in a different manner by other companies, which limits its usefulness as a comparative measure. Therefore, Free Cash Flow should be used as a supplemental measure and not in lieu of MIC’s financial results as reported under GAAP.

MIC may report certain financial metrics on a proportionately combined basis including, proportionately combined gross profit, proportionately combined EBITDA excluding non-cash items, proportionately combined cash interest, proportionately combined cash taxes, proportionately combined maintenance capital expenditures, proportionately combined Free Cash Flow, proportionately combined Free Cash Flow per share, proportionately combined growth capital expenditures and proportionately combined net debt. The Company believes that such measures provide investors and management with additional insight into the financial results and cash generated on the basis of its varied ownership interests in its businesses and investments for the reporting period.

Proportionately combined metrics used by MIC may be calculated in a different manner by other companies and may limit their usefulness as a comparative measure. Therefore, proportionately combined metrics should be used as a supplement to and not in lieu of financial results reported in accordance with GAAP.

The following table summarizes MIC’s financial performance on a proportionately combined basis during the quarter and nine month periods ended September 30, 2013 and the prior comparable periods.

IMTT

MIC has a 50% equity interest in International-Matex Tank Terminals (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 refer to results for 100% of the business, not MIC’s 50% interest.

Historically, storage rates have generally included the provision of ancillary services. More recently, IMTT’s customer contracts have unbundled a number of these services, adding or increasing separate fees for ancillary services. As such, MIC believes that terminal revenue is becoming a more relevant metric for analyzing IMTT’s performance than storage rates.

Terminal revenue increased 8.1% and 8.8% for the quarter and nine months ended September 30, 2013 as compared with 8.5% and 7.1% for the quarter and nine months ended September 30, 2012, respectively.

While average storage rental rates increased by 2.1% and 5.1% for the quarter and nine months ended September 30, 2013, respectively, as compared with 9.2% and 6.9% for the quarter and nine months ended September 30, 2012, revenue from ancillary services increased 19.4% and 15.1% for the quarter and nine months ended September 30, 2013 as compared with 4.7% and 3.2% for the quarter and nine months ended September 30, 2012. Ancillary services include throughput, pumping, as well as some blending and infrastructure usage.

Capacity utilization was 92.9% in the third quarter of 2013 compared with 93.3% in the third quarter of 2012 driven primarily by a single large tank being taken out of service for cleaning and inspection. That tank was returned to service in October 2013 and a second tank of the same size was taken out of service, also for cleaning and inspection.

After spiking in the second quarter of the year, maintenance capital expenditures decreased to $14.5 million and increased to $60.5 million for the quarter and year to date periods, respectively, in 2013 compared with $15.3 million and $30.7 million in the prior comparable periods. The majority of the year to date increase in 2013 pertains to previously disclosed costs to repair the damage from Hurricane Sandy at IMTT’s Bayonne, New Jersey facility and higher costs related to tank cleaning and repair. Maintenance capital expenditures in 2014 are expected to return to the range of levels observed in 2010 through 2012.

IMTT’s tax provision contemplates payment of approximately $13.0 million of federal income taxes and $5.6 million of state income taxes for 2013. The $13.8 million tax provision for the nine months ended September 30, 2013 includes $9.7 million for federal income taxes and $4.1 million for state income taxes.

Free Cash Flow generated by IMTT increased 30.7% to $33.2 million and decreased 8.6% to $91.9 million for the quarter and nine months ended September 30, 2013, respectively, versus the prior comparable periods in 2012. The growth in the quarter was driven primarily by the improved operating results of the business. The decline in Free Cash Flow for the year to date period stems from the higher maintenance capital expenditures incurred during the second quarter of the year and an increased interest expense that more than offset the increase in EBITDA excluding non-cash items.

IMTT declared a distribution of $20.5 million for the third quarter to each of its two shareholders on October 24, 2013.

Hawaii Gas

Hawaii Gas is the owner and operator of the only regulated (“utility”) gas processing 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.

For the third quarter of 2013 compared with the third quarter of 2012:

• Non-utility contribution margin increased 1.0% to $15.7 million from $15.5 million
• Utility contribution margin increased 1.2% to $9.4 million from $9.3 million
• The combined volume of utility and non-utility gas sold increased 0.9%

In July, Hawaii Gas entered into a new naphtha feedstock supply agreement for its utility operations. The agreement provides the business with a supply of naphtha for the period October 1, 2013 through March 31, 2014.

Hawaii Gas is progressing with initiatives related to the use of LNG (“Liquefied Natural Gas”) as a back-up fuel for its customers. On August 12, 2013, Hawaii Gas filed an application with the Hawaiian Public Utilities Commission seeking approval to use LNG as a back-up to its regulated SNG (“Synthetic Natural Gas”) system. A decision by the HPUC on the matter is expected before the end of the year. The cost of developing this project continues to negatively impact EBITDA.

The Free Cash Flow generated by Hawaii Gas increased to $9.2 million in the third quarter of 2013 from ($440,000) in the third quarter of 2012. Through the nine months ended September 30, 2013, Free Cash Flow increased 58.3% to $25.6 million from $16.2 million in the comparable period in 2012. The increase reflects primarily interest rate swap breakage costs of $8.7 million that were incurred in 2012 and not in 2013 and a decrease in the business’ tax provision. Excluding the impact of the swap break costs, underlying Free Cash Flow grew by 10.8% and 2.9% in the quarter and nine months ended September 30, 2013, respectively, versus the prior comparable periods.

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 facility in Las Vegas, Nevada that supplies both cooling and heating services to three customers there. MIC has a 50.01% (controlling) interest in District Energy. The table and discussion below refer to results for 100% of the business, not MIC’s 50.01% interest.

For the third quarter of 2013 compared with the third quarter of 2012:

• Cooling consumption revenue decreased 13.1% to $9.1 million from $10.5 million in 2012; and,
• Capacity revenue increased 3.0% to $5.8 million from $5.6 million - increases in the number of customers being served and inflation adjustments to existing contracts contributed to the improved performance.

District Energy’s results for the third quarter reflect lower average temperatures in 2013 compared with 2012 and the loss of a customer (previously disclosed) that reduced demand for cooling. The business is in dispute with the customer that terminated its contract as the customer has refused to make unamortized lease principal payments to which District Energy believes it is entitled. The parties have agreed to mediate the matter in a process that is expected to commence prior to year end.

MIC expects to commence a refinancing of the long-term debt at District Energy in the fourth quarter of 2013. The refinancing is expected to be completed in the first half of 2014 subject to market conditions remaining favorable.

Free Cash Flow generated by District Energy decreased 7.4% to $5.0 million for the third quarter of 2013 and decreased 10.6% to $10.6 million for the nine months ended September 30, 2013 versus the prior comparable periods. The decreases reflect primarily the reduction in revenue noted above partially offset by a decrease in maintenance capital expenditures.

Atlantic Aviation

Atlantic Aviation owns and operates a network of fixed-base operations (FBO) that primarily provide fuel, terminal and aircraft hangar services to owners and operators of general aviation (GA) aircraft at 62 airports in the U.S. The network is the one of the largest in the U.S. air transportation industry.

For the third quarter of 2013 compared with the third quarter of 2012:

• The volume of GA fuel sold increased by 3.5% and the average margin on GA fuel sales increased 1.2%; and,
• Non-fuel gross profit increased 8.9% primarily due to an increase in hangar and office rental revenue of 6.1%.

The performance of Atlantic Aviation is, in general, more closely tied to economic health of the U.S. as a whole than that of MIC’s other businesses. MIC believes that the improvement in gross profit generated by Atlantic Aviation is reflective of the ongoing improvement in the U.S. economy broadly, market share gains and the popularity of the destinations in the portfolio specifically.

Free Cash Flow generated by Atlantic Aviation increased 74.1% to $30.8 million and 66.8% to $85.8 million for the quarter and nine months ended September 30, 2013, respectively, versus the comparable periods in 2012. The increase in cash generation reflects primarily the reduction in the amount and cost of the business’ long-term debt outstanding versus 2012, the improved operating results and lower maintenance capital expenditures.

Free Cash Flow gains at Atlantic Aviation year to date were partially offset by an increase in the business’ provision for current income taxes of $5.6 million compared with $2.0 million through nine months in 2012. The federal portion of Atlantic Aviation’s current income taxes for 2013 is expected to be wholly offset in consolidation by the application of Net Operating Loss carryforwards at the MIC holding company level.

MIC Solar

At the quarter end September 30, 2013, MIC had invested in four contracted solar power generation facilities located in the southwestern U.S., two of which were in operation and two of which were under construction. The Company invested in a fifth facility, also under construction, following the quarter end. When completed, the combined generating capacity of the five facilities is expected to be approximately 57 megawatts of electricity. The power will be sold to nearby utilities and one U.S. Air Force base pursuant to long-term power purchase agreements.

Effective with the third quarter of 2013 the four facilities that comprised MIC Solar constituted a reportable segment under GAAP. MIC has certain rights with respect to decisions involving the management and operations of the projects in MIC Solar and has determined that it is appropriate to consolidate the projects for financial reporting purposes with its co-investor’s interest reflected as “noncontrolling interest” in the consolidated condensed financial statements.

MIC Solar’s facilities, including the two operating facilities and the two acquired in the period, performed as anticipated during the third quarter of 2013. The facilities generated a proportionately combined Free Cash Flow of approximately ($689,000) and $1.0 million for the quarter and nine months ended September 30, 2013, respectively.

MIC Solar incurred approximately $2.0 million of acquisition expenses in the third quarter related to the three facilities currently under development. These expenses contributed to the negative Free Cash Flow for the segment in the period. The two facilities in operation were cash flow positive. Free Cash Flow will be adversely affected in any quarter in which a new facility is acquired given the expenses associated with such acquisitions that cannot be capitalized.

MIC anticipates allocating approximately $35.0 million of additional capital to MIC Solar over the upcoming 12 – 18 months.
