FINANCIAL INFORMATION
Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion of the financial condition and results of operations of Macquarie Infrastructure Corporation (MIC) should be read in conjunction with the consolidated condensed financial statements and the notes to those statements included elsewhere herein.
MIC is a Delaware corporation formed on May 21, 2015. MIC’s predecessor, Macquarie Infrastructure Company LLC, was formed on April 13, 2004. Except as otherwise specified, all references in this Form 10-Q to “MIC”, “we”, “us”, and “our” refer to Macquarie Infrastructure Corporation and its subsidiaries.
MIC is externally managed by Macquarie Infrastructure Management (USA) Inc. (our Manager), pursuant to the terms of a Management Services Agreement, subject to the oversight and supervision of our Board. Six of the eight members of our Board, and all members of each of our Audit, Compensation, and Nominating and Governance Committees, are independent and have no affiliation with Macquarie. Our Manager is a member of the Macquarie Group of companies comprising Macquarie Group Limited and its subsidiaries and affiliates worldwide. Macquarie Group Limited is headquartered in Australia and is listed on the Australian Securities Exchange.
We currently own and operate businesses that provide products and services to corporations, government agencies, and individual customers in the United States (U.S.). Our operations are organized into three segments:
Atlantic Aviation: a provider of fuel, terminal, aircraft hangaring, and other services primarily to owners and operators of general aviation (GA) jet aircraft at 69 airports throughout the U.S.;
MIC Hawaii: comprising an energy company that processes and distributes gas and provides related services (Hawaii Gas) and several smaller businesses collectively engaged in efforts to reduce the cost and improve the reliability and sustainability of energy in Hawaii; and
Corporate and Other: comprising a holding company headquartered in New York City, MIC Corporate, and a shared services center in Plano, Texas, MIC Global Services.
On October 31, 2019, in addition to the active management of our existing portfolio of businesses, we announced our intention to pursue strategic alternatives and have since been engaged in processes that could result in the sale of our Company or one or more of our operating businesses. During the quarter ended September 30, 2020, International-Matex Tank Terminals (IMTT) was classified as a discontinued operation and eliminated as a reportable segment. All periods reported herein reflect this change. In December 2020, we completed the sale of IMTT (IMTT Transaction).
On March 30, 2021, MIC entered into an agreement and plan of merger (the Merger Agreement) with Macquarie Infrastructure Holdings, LLC (Holdings LLC), a recently formed Delaware limited liability company and a direct wholly-owned subsidiary of MIC, and Plum Merger Sub, Inc., a recently formed Delaware corporation and a direct wholly owned subsidiary of Holdings LLC (Merger Sub), providing for Merger Sub to merge with and into MIC (the Merger), resulting in MIC becoming a direct wholly-owned subsidiary of Holdings LLC, which will become publicly-traded, subject to the satisfaction of certain closing conditions (including the approval of the Company’s shareholders). Upon the effectiveness of the Merger, each share of the Company’s common stock will be converted into one Holdings LLC common unit. Following the consummation of the Merger, it is anticipated that a direct subsidiary of MIC will distribute all of the limited liability company interests in MIC Hawaii Holdings, LLC (MIC Hawaii) to MIC and MIC will in turn distribute such limited liability company interests to Holdings LLC (such distributions, together with the merger, the “Reorganization”). MIC Hawaii holds the businesses comprising the Company’s MIC Hawaii business segment. MIC believes that the Reorganization will provide flexibility to pursue the sale or sales of the Company’s remaining operating businesses in any sequence without altering the after-tax net proceeds to shareholders. Following receipt of shareholder approval of the Merger, the Board intends to evaluate the status of efforts to sell MIC or its remaining operating businesses, and complete the Reorganization at such time as it determines will be in the best interests of the Company and its shareholders. The Board currently anticipates implementing the Reorganization following execution of a definitive agreement for, and prior to completing, the sale of the Atlantic Aviation business. The Board may abandon or postpone the Merger at any time prior to its effective time.
Overview
Use of Non-GAAP measures
In addition to our results under U.S. GAAP, we use certain non-GAAP measures including EBITDA excluding non-cash items and Free Cash Flow to assess the performance and prospects of our businesses.
1

TABLE OF CONTENTS
We measure EBITDA excluding non-cash items as it reflects our businesses’ ability to effectively manage the amount of products sold or services provided, the operating margin earned on those transactions, and the management of operating expenses independent of the capitalization and tax attributes of those businesses.
In analyzing the financial performance of our businesses, we focus primarily on cash generation and Free Cash Flow in particular. We believe investors use Free Cash Flow to assess our ability to fund acquisitions, invest in growth projects, reduce or repay indebtedness, and/or return capital to shareholders.
See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Results of Operations — Consolidated — Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) excluding non-cash items and Free Cash Flow” for further information on our calculation of EBITDA excluding non-cash items and Free Cash Flow and for reconciliations of these non-GAAP measures to the most comparable GAAP measures.
Recent Developments
2.00% Convertible Senior Notes Tender
On February 17, 2021, we initiated a tender offer for any and all of our 2.00% Convertible Senior Notes outstanding. On March 16, 2021, we repurchased $358.6 million in aggregate principal amount of the Notes in the tender offer. In April 2021, we repurchased an additional $5.7 million resulting in an outstanding balance of $38.2 million.
Hawaii Gas Senior Secured Notes
On April 19, 2021, The Gas Company, LLC (d.b.a. Hawaii Gas) fully repaid all of its $100.0 million senior secured notes outstanding and incurred a $4.7 million 'make-whole' payment.
MIC Global Services
In connection with sales processes for our businesses, we are allocating personnel and costs associated with our shared services center in Plano, TX, other than functions supporting the public company, to Atlantic Aviation and adding resources to our MIC Hawaii business such that it can operate on a stand-alone basis.
Historical Dividends
Since January 1, 2020, MIC has paid or declared the following dividends:

___________
(1)Special dividend declared and paid out of the net proceeds from the IMTT Transaction. Shares of MIC traded with “due-bills” attached through January 8, 2021 and traded ex-dividend on January 11, 2021.
We intend to provide investors with the benefits of investing in infrastructure and infrastructure-like businesses that we believe will generate growing amounts of cash flow over time as a result of their positive correlation with inflation and provision of basic services to customers. Historically, we have used most of the distributable cash flow to support the payment of quarterly dividends. On April 2, 2020, in response to the effects of COVID-19 on the performance and prospects of our businesses, we suspended our quarterly cash dividend. On December 23, 2020, following the successful completion of the IMTT Transaction, our Board authorized the payment of a special dividend of $11.00 per share in cash comprising the net proceeds from the IMTT Transaction after paying or reserving for capital gains taxes, transaction costs, a Disposition Payment, and the retirement of holding company level debt. As a result of the IMTT Transaction, our ability to generate distributable cash flow in the future has been reduced.
Consistent with our focus on preparing our businesses for and completing a sale or sales of our operating businesses, it is likely that the majority of any Free Cash Flow in 2021 will be deployed completing projects to which we have committed and reducing indebtedness generally. Although our Board regularly reviews our dividend policy, it is unlikely that it will authorize the payment of a regular dividend in 2021 while the sale of the Company or its operating businesses is being actively pursued. Consistent with the outcome of the IMTT Transaction, we expect that the net proceeds from any future sale would also be distributed to stockholders.
In determining whether to pay dividends in the future, our Board will take into account such matters as the ability of our businesses to generate Free Cash Flow, our progress with respect to a sale or sales of our operating businesses, the state of the capital markets and general business and economic conditions, the short and long term impacts of, and disruptions in our businesses, and/or in the business or economic environment due to COVID-19, or other non-economic events, the Company’s

Results of Operations: Consolidated
Impact of COVID-19
We continue to closely monitor the effects of COVID-19 and are actively managing our response by placing a priority on the health and safety of our employees, contractors, their families, customers, and the broader communities in which our businesses operate. Both Atlantic Aviation and the MIC Hawaii businesses are classified as essential services businesses and remain fully operational. The businesses are adhering to pandemic response plans and are following guidance from the Centers for Disease Control and Prevention (CDC) as well as federal, state, and local governments with respect to conducting operations safely. To the extent possible, and as permitted by local guidelines, our businesses are facilitating vaccination of their employees against COVID-19.
In addition to standard operating procedures designed to maintain safe operations, our businesses have implemented additional measures including: (i) a work from home policy for all employees that are able to do so; (ii) enhancing cleaning and disinfecting of facilities; (iii) limiting interactions between employees and customers through social distancing; (iv) mandating the use of personal protective equipment by employees; (v) modifying shift schedules to reduce exposure between shifts; and (vi) educating customers on alternative payment and customer care options as a means of limiting interactions with employees at MIC Hawaii. All of the MIC businesses are engaged in ongoing communications with employees, customers, vendors, lenders, and other stakeholders apprising them of the business' response to the pandemic. We believe our staff and customers can access our facilities safely and in compliance with relevant directives.
COVID-19 continues to negatively affect the performance of our businesses, although the effects have diminished relative to this time last year. Some of the federal, state, and local governments' pandemic response measures including social distancing, quarantines, travel restrictions, prohibitions on public gatherings, and stay-at-home orders have been rolled back. Despite the roll back, GA flight activity and the demand for jet fuel and ancillary services provided by Atlantic Aviation continues to be affected by COVID-19. The easing of travel restrictions has resulted in an increase in economic activity and the number of visitors to Hawaii, but not to pre-COVID-19 levels. The widespread availability of COVID-19 vaccines is expected to have a positive effect on activity levels at our businesses.
Changes in GA flight activity relative to the levels achieved in the first quarter of 2021 will depend upon the duration of the pandemic, any governmental response including renewed travel restrictions, and the state of the U.S. and global economies, as well as increases in business, international, and event-driven activity all of which are uncertain. Visitor arrivals to Hawaii, the primary driver of increases in demand for gas in Hawaii, improved gradually during the first quarter of 2021 over the fourth quarter of 2020 following the implementation of a quarantine exemption for visitors with evidence of a negative COVID-19 test prior to arrival in the islands and increased visitor confidence levels due to the availability of COVID-19 vaccines. The rate of recovery in the number of visitors to Hawaii going forward is uncertain.
Cost saving initiatives implemented over the past year including hiring freezes, reductions in regular hours and overtime, furloughs, deferral of maintenance and repair work have been eased as demand for services has increased. While management of our businesses remain focused on conducting operations as efficiently as possible, we believe that the cash generated by their ongoing operations will be sufficient to fund our businesses, including committed growth projects.
In addition to the cash generated by our operating businesses, our sources of funding include the $359.5 million of cash we had on hand on March 31, 2021. The $359.5 million is net of amounts used or reserved for capital gains taxes paid in April 2021 in relation to the IMTT Transaction and the repurchase of any and all of our 2.00% Convertible Senior Notes outstanding. In April 2021, we repaid all of the $100.0 million senior secured notes outstanding at MIC Hawaii and incurred a $4.7 million 'make-whole' payment. See Recent Developments above.

Revenue
Consolidated revenues decreased for the quarter ended March 31, 2021 compared with the quarter ended March 31, 2020 primarily due to (i) a decrease in the amount of jet fuel sold by Atlantic Aviation and gas sold by MIC Hawaii; and (ii) a lower wholesale cost of jet fuel, attributable to the impact of COVID-19.

Results of Operations: Consolidated – (continued)
Cost of Services and Product Sales
Consolidated cost of services and cost of product sales decreased for the quarter ended March 31, 2021 compared with the quarter ended March 31, 2020 primarily due to (i) a decrease in the amount of jet fuel sold by Atlantic Aviation and gas sold by MIC Hawaii; and (ii) a lower wholesale cost of jet fuel, attributable to the impact of COVID-19. In addition, the decrease in cost of product sales reflects a favorable mark-to-market adjustment of the value of the commodity hedge contracts for its wholesale liquified petroleum gas (LPG) purchases on MIC Hawaii's balance sheet (see “Results of Operations — MIC Hawaii” below).
Selling, General and Administrative Expenses
Selling, general and administrative expenses decreased for the quarter ended March 31, 2021 compared with the quarter ended March 31, 2020 primarily due to lower costs incurred in connection with efforts to sell our businesses and decreases in salary and benefits and professional services. The decrease in selling, general and administrative expenses was partially offset by costs incurred related to the tender offer for our 2.00% Convertible Senior Notes and higher insurance costs.
Fees to Manager
Our Manager is entitled to a monthly base management fee based on our market capitalization and potentially a quarterly performance fee based on total stockholder returns relative to a U.S. utilities index. For the quarters ended March 31, 2021 and 2020, we incurred base management fees of $5.6 million and $7.4 million, respectively. The decrease in base management fees reflects a reduction in our average market capitalization (primarily as a result of the IMTT Transaction) and the increase in our average holding company cash balance during the quarter ended March 31, 2021. No performance fees were incurred in either of the current or prior comparable period. The unpaid portion of base management fees and performance fees, if any, at the end of each reporting period is included in the line item Due to Manager-related party in our consolidated condensed balance sheets.
In accordance with the Management Services Agreement, our Manager elected to reinvest any fees to which it was entitled in new primary shares in the periods shown below and has currently elected to reinvest future base management fees and performance fees, if any, in new primary shares.

Depreciation and Amortization
The decrease in depreciation and amortization expense for the quarter ended March 31, 2021 compared with the quarter ended March 31, 2020 primarily reflects the full amortization of certain airport contract rights at Atlantic Aviation, partially offset by assets placed in service.

TABLE OF CONTENTS
Results of Operations: Consolidated – (continued)
Interest Expense, net, and Gains (Losses) on Derivative Instruments
Interest expense, net, includes non-cash gains on derivative instruments of $281,000 and non-cash losses of $4.3 million for the quarters ended March 31, 2021 and 2020, respectively, and amortization of deferred financing costs and debt discount. Gains (losses) on derivatives recorded in interest expense are attributable to the change in fair value of interest rate hedges. For the quarter ended March 31, 2021, interest expense also includes non-cash write-offs of deferred financing costs of $4.3 million related to the repurchase of our 2.00% Convertible Senior Notes and the cancellation of the holding company revolving credit facility.
Excluding these non-cash adjustments and write-offs, cash interest expense totaled $13.1 million and $18.6 million for the quarters ended March 31, 2021 and 2020, respectively. The decrease in cash interest expense primarily reflects a lower weighted average debt balance and a lower weighted average interest rate. See discussions of interest expense for each of our operating businesses below.
Other Income (Expense), net
For the quarter ended March 31, 2021, other income (expense), net, primarily includes income in relation to a Transition Services Agreement with IMTT.
Discontinued Operations
For the quarter ended March 31, 2020, discontinued operations reflects the operating results of IMTT. The IMTT Transaction closed on December 23, 2020.
Income Taxes
We file a consolidated federal income tax return that includes the financial results of our operating businesses, Atlantic Aviation and MIC Hawaii. Pursuant to a tax sharing agreement, these businesses pay MIC an amount equal to the federal income tax each would pay on a standalone basis if they were not part of the consolidated group. For 2021, we expect our current federal income tax liability to be approximately $1.5 million.
In addition, our businesses file income tax returns and may pay taxes in the states and local jurisdictions in which they operate. We expect the aggregate current year state income tax liability to be approximately $7.0 million. In calculating our state income tax provision, we have provided a valuation allowance for certain state income tax NOL carryforwards, the use of which is uncertain.

Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) excluding non-cash items and Free Cash Flow
In addition to our results under U.S. GAAP, we use the non-GAAP measures EBITDA excluding non-cash items and Free Cash Flow to assess the performance and prospects of our businesses.
We measure EBITDA excluding non-cash items as it reflects our businesses’ ability to effectively manage the amount of products sold or services provided, the operating margin earned on those transactions, and the management of operating expenses independent of the capitalization and tax attributes of those businesses.
We believe investors use EBITDA excluding non-cash items primarily as a measure of the operating performance of MIC’s businesses and to make comparisons with the operating performance of other businesses whose depreciation and amortization expense may vary from ours, particularly where acquisitions and other non-operating factors are involved. We define EBITDA excluding non-cash items as net income (loss) or earnings — the most comparable GAAP measure — before interest, taxes, depreciation and amortization, and non-cash items including impairments, unrealized derivative gains and losses, adjustments for other non-cash items, and pension expense reflected in the statements of operations. Other non-cash items, net, excludes the adjustment to bad debt expense related to the specific reserve component, net of recoveries. EBITDA excluding non-cash items also excludes base management fees and performance fees, if any, whether paid in cash or stock.
Our businesses are characteristically owners of high-value, long-lived assets capable of generating substantial Free Cash Flow. We define Free Cash Flow as cash from operating activities — the most comparable GAAP measure — less maintenance capital expenditures and adjusted for changes in working capital.
We use Free Cash Flow as a measure of our ability to fund acquisitions, invest in growth projects, reduce or repay indebtedness, and/or return capital to shareholders. GAAP metrics such as net income (loss) do not provide us with the same level of visibility into our performance and prospects as a result of: (i) the capital intensive nature of our businesses and the generation of non-cash depreciation and amortization; (ii) shares issued to our external Manager under the Management Services Agreement; (iii) our ability to defer all or a portion of current federal income taxes; (iv) non-cash mark-to-market adjustment of the value of derivative instruments; (v) gains (losses) related to the write-off or disposal of assets or liabilities; (vi) non-cash compensation expense incurred in relation to the incentive plans for senior management of our operating businesses; and (vii) pension expenses. Pension expenses primarily consist of interest expense, expected return on plan assets, and amortization of actuarial and performance gains and losses. Any cash contributions to pension plans are reflected as a reduction to Free Cash Flow and are not included in pension expense. We believe that external consumers of our financial statements, including investors and research analysts, use Free Cash Flow to assess the Company's ability to fund acquisitions, invest in growth projects, reduce or repay indebtedness, and/or return capital to shareholders.
In this Quarterly Report on Form 10-Q, we have disclosed Free Cash Flow on a consolidated basis and for each of our operating segments and for Corporate and Other. We believe that both EBITDA excluding non-cash items and Free Cash Flow support a more complete and accurate understanding of the financial and operating performance of our businesses than would otherwise be achieved using GAAP results alone.
Free Cash Flow does not take into consideration required payments on indebtedness and other fixed obligations or other cash items that are excluded from our definition of Free Cash Flow. We note that Free Cash Flow may be calculated differently by other companies thereby limiting its usefulness as a comparative measure. Free Cash Flow should be used as a supplemental measure to help understand our financial performance and not in lieu of our financial results reported under GAAP.
Classification of Maintenance Capital Expenditures and Growth Capital Expenditures
We categorize capital expenditures as either maintenance capital expenditures or growth capital expenditures. As neither maintenance capital expenditure nor growth capital expenditure is a GAAP term, we have adopted a framework to categorize specific capital expenditures. In broad terms, maintenance capital expenditures primarily maintain our businesses at current levels of operations, capability, profitability or cash flow, while growth capital expenditures primarily provide new or enhanced levels of operations, capability, profitability or cash flow. We consider various factors in determining whether a specific capital expenditure will be classified as maintenance or growth.
We do not bifurcate specific capital expenditures into maintenance and growth components. Each discrete capital expenditure is considered within the above framework and the entire capital expenditure is classified as either maintenance or growth.

TABLE OF CONTENTS

Results of Operations: Atlantic Aviation
At Atlantic Aviation, our focus is on the sale of jet fuel and other services to operators of GA aircraft through our network of 69 FBOs. The financial performance of the business is positively correlated with the number of GA flight movements (take-offs and landings) in the U.S. and the business’ ability to service a portion of the aircraft involved in those operations. Over the long-term, the rate of growth in GA flight movements has tended to be positively correlated with the level of economic activity in the U.S.
GA flight activity continues to recover from the effects of COVID-19. Based on data reported by the Federal Aviation Administration (FAA), industry-wide domestic GA flight movements for the quarter ended March 31, 2021 increased 8% compared with the quarter ended March 31, 2020 and decreased 3% compared with the quarter ended March 31, 2019.
Based on data reported by the FAA, the total number of GA flight movements at airports on which Atlantic Aviation operates for the first quarter ended March 31, 2021 increased 5% compared with the quarter ended March 31, 2020 and decreased by 6% compared with the quarter ended March 31, 2019. As compared with 2019, the decrease in activity at these airports was greater than the decline in overall domestic U.S. flight activity for the same periods primarily due to Atlantic Aviation's exposure to centers of business and economic activity such as New York, Los Angeles, and Chicago where the rate of recovery in economic activity has been slower than average. Atlantic Aviation has experienced stronger performance in other markets including the Intermountain West and Florida which saw GA flight activity in excess of 2019 levels.
In response to the downturn in flight activity that commenced in March of 2020, Atlantic Aviation engaged in a thorough review of its operational and capital expenditures to ensure it was prudently managing its liquidity. As activity levels have recovered, certain of the cost reductions previously implemented have been reversed. Expenses are being carefully managed to prudent levels for current activity.
Atlantic Aviation seeks to extend FBO leases prior to their maturity to maintain visibility into the cash generating capacity of these assets over the long-term. The weighted average remaining life of the leases in the Atlantic Aviation portfolio, based on EBITDA excluding non-cash items in the prior calendar year adjusted for the impact of acquisitions, dispositions, and lease extensions was 21.8 years and 19.6 years on March 31, 2021 and 2020, respectively. A portion of the increase reflects potentially temporary changes in the contribution to EBITDA excluding non-cash items from certain FBOs due to COVID-19. Based on the EBITDA excluding non-cash items weighting in 2019, the remaining lease life on March 31, 2021 would have been 19.9 years.

Atlantic Aviation generates most of its revenue from sales of jet fuel at facilities located on the 69 U.S. airports on which the business operates. Increases and decreases in the wholesale cost of jet fuel are generally passed through to customers. Atlantic Aviation seeks to maintain and, where appropriate, increase dollar-based margins on jet fuel sales.
Accordingly, reported revenue will fluctuate based on the wholesale cost of jet fuel to Atlantic Aviation and may not reflect the business’ ability to effectively manage the amount of jet fuel sold and the margin achieved on those sales. For example, an increase in revenue may be attributable to an increase in the wholesale cost of jet fuel and not an increase in the amount of jet

fuel sold or margin per gallon. Conversely, a decline in revenue may be attributable to a decrease in the wholesale cost of jet fuel and not a reduction in the amount of jet fuel sold or margin per gallon.
Gross margin, which we define as revenue less cost of services, excluding depreciation and amortization, is the effective “top line” for Atlantic Aviation as it reflects the business’ ability to drive growth in the amount of products and services sold and the margins earned on those sales over time. We believe that our investors view gross margin as reflective of our ability to manage the amount and price of jet fuel sold, notwithstanding variances in the wholesale cost of jet fuel through the commodity cycle. Gross margin can be reconciled to operating income — the most comparable GAAP measure — by subtracting selling, general and administrative expenses and depreciation and amortization in the table above.
Revenue and Gross Margin
Revenue and gross margin decreased for the quarter ended March 31, 2021 compared with the quarter ended March 31, 2020 due to a reduction in the amount of jet fuel sold and a decrease in ancillary services provided, attributable to the effects of COVID-19. The reduced amount of revenue also reflects the lower wholesale cost of jet fuel in the quarter ended March 31, 2021 versus the prior comparable period. In general, the decrease in the wholesale cost of jet fuel is typically reflected in a corresponding decrease in cost of services, resulting in no impact to gross margin.
Selling, General and Administrative Expenses
Selling, general and administrative expenses decreased for the quarter ended March 31, 2021 versus the prior comparable period primarily due to lower salaries and benefits, credit card fees, and professional services.
Depreciation and Amortization
Depreciation and amortization decreased for the quarter ended March 31, 2021 versus the prior comparable period primarily due to the full amortization of certain airport contract rights, partially offset by assets placed in service.
Operating Income
Operating income increased in the quarter ended March 31, 2021 compared with the quarter ended March 31, 2020 due to the decrease in depreciation and amortization and selling, general and administrative expenses, partially offset by the decrease in gross margin.
Interest Expense, Net
Interest expense, net, includes non-cash losses on derivative instruments of an insignificant amount for the quarter ended March 31, 2021 compared with non-cash losses of $3.4 million for the quarter ended March 31, 2020, and amortization of deferred financing costs. Excluding the non-cash adjustments, cash interest expense totaled $9.8 million and $13.7 million for the quarters ended March 31, 2021 and 2020, respectively. The decrease in cash interest expense primarily reflects a lower weighted average interest rate and lower weighed average debt balance.
Income Taxes
The taxable income generated by Atlantic Aviation is reported on our consolidated federal income tax return. The business files standalone state income tax returns in most of the states in which it operates. The tax expense in the table above includes both state income taxes and the portion of the consolidated federal income tax liability attributable to the business. For the year ended December 31, 2021, the business expects to pay state income taxes of approximately $6.5 million. The Provision for Current Income Taxes of $4.5 million for the quarter ended March 31, 2021 in the above table includes primarily $2.4 million of federal income tax expense and $2.1 million of state income tax expense.
Atlantic Aviation has state NOL carryforwards that are specific to the state in which they were generated. The utilization of NOL carryforwards may reduce or eliminate state taxable income in the future.
Maintenance Capital Expenditures
For the quarter ended March 31, 2021, Atlantic Aviation incurred maintenance capital expenditures of $2.6 million and $3.4 million on an accrual basis and cash basis, respectively, compared with $3.0 million and $5.6 million on an accrual basis and cash basis, respectively, for the quarter ended March 31, 2020.

TABLE OF CONTENTS
Results of Operations: MIC Hawaii
MIC Hawaii comprises Hawaii Gas and several smaller businesses collectively engaged in efforts to reduce the cost and improve the reliability and sustainability of energy in Hawaii. The businesses of MIC Hawaii generate revenue primarily from the provision of gas to commercial, residential, and governmental customers and the generation of power.
The financial performance of MIC Hawaii is a function of the number of customers served, their consumption of energy and the prices achieved on sales by each of Hawaii Gas’s utility and non-utility operations and under power purchase agreements. The amount of gas consumed is correlated with visitor arrivals and general economic activity over the long term. Consumption trends and rates are a function of, among other factors, energy efficiency, weather, the range of competitive energy sources, and MIC Hawaii’s input commodity costs.
The financial performance of MIC Hawaii continues to be affected by a reduction in the demand for gas resulting from the 60% and 67% decline in the number of visitors to Hawaii during the quarter ended March 31, 2021 compared with the quarters ended March 31, 2020 and 2019, respectively. A corresponding decline in hotel occupancy, restaurants patronage, and use of commercial laundry services resulted in an overall reduction in gas consumption of 18% and 21% during the quarter ended March 31, 2021 compared with the quarters ended March 31, 2020 and 2019, respectively.
Hawaii Gas enters into commodity hedge contracts in an effort to reduce financial risks of commodity price fluctuations associated with its wholesale LPG purchases. The business has entered into such contracts with varying maturities through December 2023 with respect to a portion of its expected LPG sales during that time.
Hawaii Gas is in regular communication with key counterparties including its supplier of naphtha feedstock for its utility operations and its LPG supplier. A new naphtha feedstock agreement effective through December 2023 was approved on an interim basis by the Hawaii Public Utilities Commission (HPUC) in December 2020.
The HPUC issued an order on April 9, 2021 establishing a procedural schedule to govern the remanded 2018 rate case proceeding and directed Hawaii Gas to update its 2018 test year data to reflect a 2022 test year and submit certain analysis related to greenhouse gas lifecycle emissions associated with two small scale liquefied natural gas (LNG) projects. The HPUC order also expanded the scope of participation of certain parties and established a modified statement of issues. The ultimate impact of the HPUC order on the approved revenue requirement is unclear; however, the remanded proceeding is not expected to be adjudicated completely in 2021, which would result in no anticipated financial impact in 2021.

Hawaii Gas generates most of its revenue from the sale of gas. Accordingly, revenue can fluctuate based on the wholesale cost of gas and/or feedstock to Hawaii Gas and may not reflect the business’ ability to effectively manage the amount of gas sold and the margins achieved on those sales. For example, an increase in revenue may be attributable to an increase in the wholesale cost of gas passed through to Hawaii Gas’ customers and not an increase in the amount of gas sold or margin achieved. Conversely, a decline in revenue may be attributable to a decrease in the wholesale cost of gas passed through to Hawaii Gas’ customers and not a reduction in the amount of gas sold or margin achieved.
Gross margin, which we define as revenue less cost of product sales, excluding depreciation and amortization, is the effective “top line” for Hawaii Gas as it is reflective of the business’ ability to drive growth in the amount of products sold and the margins earned on those sales over time. We believe that investors use gross margin to evaluate the business as it is reflective of our performance in managing volume and price throughout the commodity cycle. Gross margin is reconciled to operating income — the most comparable GAAP measure — by subtracting selling, general and administrative expenses and depreciation and amortization in the table above.
Revenue and Gross Margin
Revenue declined for the quarter ended March 31, 2021 compared with the quarter ended March 31, 2020 primarily due to a decrease in the amount of gas sold by Hawaii Gas. The decrease in the amount of gas sold reflects a decrease in consumption of gas, mainly by commercial and industrial customers, as a result of a reduction in the number of visitors to Hawaii and reduced commercial activity due to the impact of COVID-19.
Gross margin increased to $19.8 million for the quarter ended March 31, 2021 from $18.5 million for the quarter ended March 31, 2020. The increase in gross margin was primarily due to favorable changes in the mark-to-market adjustment of the value of the commodity hedge contracts on MIC Hawaii's balance sheet, partially offset by a decrease in the amount of gas sold due to the impact of COVID-19. The business recorded favorable adjustments of $1.1 million in the mark-to-market adjustment of the value of the commodity hedge contracts for the quarter ended March 31, 2021 compared with an unfavorable adjustment of $2.4 million for the quarter ended March 31, 2020. The change in the mark-to-market adjustment of the value of the commodity hedge contracts during the quarter ended March 31, 2021 reflects higher forecast wholesale prices of LPG relative to the hedged price.
Selling, General and Administrative Expenses
Selling, general and administrative expenses decreased for the quarter ended March 31, 2021 compared with the prior comparable period primarily due to decreases in salaries and benefits and professional fees, partially offset by an increase in insurance costs.
Operating Income
Operating income increased for the quarter ended March 31, 2021 compared with the quarter ended March 31, 2020 primarily due to the increase in gross margin and lower selling, general and administrative expenses, partially offset by an increase in depreciation and amortization.
Interest Expense, Net
Interest expense, net, includes non-cash gains on derivative instruments of $283,000 and non-cash losses of $833,000 for the quarters ended March 31, 2021 and 2020, respectively, and amortization of deferred financing costs. Excluding the non-cash adjustments, cash interest expense totaled $1.5 million and $1.8 million for the quarters ended March 31, 2021 and 2020, respectively. The decrease in cash interest expense primarily reflects a lower weighted average interest rate.
Income Taxes
The taxable income generated by the MIC Hawaii businesses is reported on our consolidated federal income tax return. The businesses file a consolidated Hawaii state income tax return. The tax expense in the table above includes both the state income tax and the portion of the consolidated federal income tax liability attributable to the businesses. For the year ended December 31, 2021, the business expects to pay state income taxes of approximately $500,000. The Provision for Current Income Taxes of $1.5 million for the quarter ended March 31, 2021 in the above table includes primarily $1.2 million of federal income tax expense and $342,000 of state income tax expense.
Maintenance Capital Expenditures
For the quarter ended March 31, 2021, MIC Hawaii incurred maintenance capital expenditures of $1.1 million and $1.4 million on an accrual and cash basis, respectively, compared with $2.7 million and $2.4 million on an accrual and cash basis, respectively, for the quarter ended March 31, 2020.

Fees to Manager
Fees to Manager comprise base management fees of $5.6 million and $7.4 million for the quarters ended March 31, 2021 and 2020, respectively. The decrease in base management fees reflects a reduction in our average market capitalization (primarily as a result of the IMTT Transaction) and the increase in our average holding company cash balance during the quarter ended March 31, 2021. No performance fees were incurred in either of the current or prior comparable period.
Interest Expense, net
Interest expense, net, includes non-cash amortization of deferred financing costs and debt discounts. For the quarter ended March 31, 2021, interest expense also includes non-cash write-offs of deferred financing costs of $4.3 million related to the repurchase of our 2.00% Convertible Senior Notes and the cancellation of the holding company revolving credit facility.
Excluding these non-cash adjustments and write-offs, cash interest expense totaled $1.7 million and $3.1 million for the quarters ended March 31, 2021 and 2020, respectively. The decrease in cash interest expense primarily reflects a lower weighted average debt balance and a lower weighted average interest rate.

TABLE OF CONTENTS

Liquidity and Capital Resources
General
Cash requirements of our operating businesses include primarily normal operating expenses, debt service, debt principal payments, payments of dividends to our holding company, and capital expenditures. Their source of cash has been primarily operating activities although we have drawn on and may in the future draw on credit facilities, have issued and may in the future issue new equity or debt, and have sold and may in the future sell assets to generate cash.
We may from time to time seek to purchase or retire our outstanding debt in open market purchases, privately negotiated transactions or otherwise. Such repurchases, if any, could be material and will depend on market conditions, our liquidity needs, and other factors.
2.00% Convertible Senior Notes Tender
On February 17, 2021, we initiated a tender offer for any and all of our 2.00% Convertible Senior Notes outstanding. On March 16, 2021, we repurchased $358.6 million in aggregate principal amount of the Notes in the tender offer. In April 2021, we repurchased an additional $5.7 million resulting in an outstanding balance of $38.2 million.
Hawaii Gas Senior Secured Notes
On April 19, 2021, The Gas Company, LLC (d.b.a. Hawaii Gas) fully repaid all of its $100.0 million senior secured notes outstanding and incurred a $4.7 million 'make-whole' payment.
Cancellation of Holding Company Revolving Credit Facility
The IMTT Transaction resulted in the termination of all commitments under our holding company level revolving credit facility on January 19, 2021, in accordance with the terms of that agreement. All drawings on the revolving credit facility were fully repaid as of December 31, 2020.
Ongoing Operations
We currently expect to fund our operations, service and/or repay our debt, make required tax payments, fund maintenance capital expenditures, and deploy growth capital during 2021 using cash generated from the operations of our operating businesses and our $359.5 million of cash on hand on March 31, 2021. The $359.5 million is net of amounts used or reserved for capital gains taxes paid in April 2021 and the repurchase of any and all of our 2.00% Convertible Senior Notes outstanding. As noted above, in April 2021, we repaid all of the $100.0 million senior secured notes outstanding at MIC Hawaii and incurred a $4.7 million 'make-whole' payment.
On March 31, 2021, the consolidated debt outstanding at our operating businesses and at our holding company totaled $1.2 billion. We had access to an undrawn revolving credit facility at MIC Hawaii of $60.0 million. The ratio of net debt/EBITDA for our operating businesses was 3.8x on March 31, 2021.

We generally capitalize our businesses in part using floating rate debt with medium-term maturities of between four and seven years. We also use longer dated private placement debt and other forms of capital including bond or hybrid debt instruments to capitalize our businesses. In general, the debt facilities of our businesses are non-recourse to the holding company and there are no cross-collateralization or cross-guarantee provisions in these facilities.

Analysis of Consolidated Historical Cash Flows from Continuing Operations
The following section discusses our sources and uses of cash on a consolidated basis from continuing operations. All intercompany activities such as corporate allocations, capital contributions to our businesses, and distributions from our businesses have been excluded from the table as these transactions are eliminated on consolidation.

Operating Activities from Continuing Operations
Cash provided by (used in) operating activities is generally comprised of EBITDA excluding non-cash items (as defined by us), less cash interest, cash taxes, and pension payments, and changes in working capital. See “Management's Discussion and Analysis of Financial Condition and Results of Operations - Results of Operations” for discussions around the components of EBITDA excluding non-cash items on a consolidated basis from continuing operations and for each of our operating businesses and Corporate and Other above.
The decrease in consolidated cash provided by operating activities for the quarter ended March 31, 2021 compared with the quarter ended March 31, 2020 was primarily due to:
an unfavorable change to accounts receivable and inventory and favorable change to accounts payable resulting from the decline in business activity and cost of jet fuel and gas from the initial impact of COVID-19 in March 2020; and
payment of expenses related to the IMTT Transaction in the first quarter of 2021; partially offset by
an increase in EBITDA excluding non-cash items; and
decrease in cash interest expense and current taxes.
Investing Activities from Continuing Operations
Cash provided by investing activities include proceeds from divestitures of businesses and disposal of fixed assets. Cash used in investing activities include acquisitions of businesses in existing segments and capital expenditures.
The decrease in cash used in investing activities for the quarter ended March 31, 2021 compared with the quarter ended March 31, 2020 is primarily attributable to the absence of an acquisition of an FBO during 2020 at an airport on which Atlantic Aviation already operated and the decrease in capital expenditures.
Capital Deployment
Capital deployment includes growth capital expenditures and “bolt-on” acquisitions, the majority of which are expected to generate incremental earnings. For the quarters ended March 31, 2021 and 2020, growth capital deployed from continuing operations totaled $11.1 million and $22.4 million, respectively. We continuously evaluate opportunities to prudently deploy capital in bolt-on acquisitions and growth projects across our existing businesses.
Financing Activities from Continuing Operations
Cash provided by financing activities includes new equity and debt issuance primarily to fund acquisitions and capital expenditures. Cash used in financing activities includes dividends paid to our stockholders and the repayment of debt principal balances.
The change from cash provided by financing activities for the quarter ended March 31, 2020 to cash used in financing activities for the quarter ended March 31, 2021 is primarily attributable to a special dividend paid in January 2021 and the repurchase of our 2.00% Convertible Senior Notes in March 2021. For the quarter ended March 31, 2020, the Company drew down on its available revolving credit facilities in response to the outbreak of COVID-19.

Quantitative and Qualitative Disclosures About Market Risk
For quantitative and qualitative disclosures about market risk, see Part II, Item 7A “Quantitative and Qualitative Disclosures about Market Risk” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020. Our exposure to market risk has not changed materially since February 17, 2021, the filing date for our Annual Report on Form 10-K, except for the impact of higher wholesale LPG prices on our commodity hedge contracts.
Interim Goodwill Review
We test for goodwill impairment at the reporting unit level on October 1st of each year and between annual tests if a triggering event indicates the possibility of an impairment. We monitor changing business conditions as well as industry and economic factors, among others, for events which could trigger the need for an interim impairment analysis. During the quarter ended March 31, 2021, there were no triggering events indicating goodwill impairment.
Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Under the direction and with the participation of our Chief Executive Officer and Chief Financial Officer, we evaluated our disclosure controls and procedures (as such term is defined under Rule 13a-15(e) and 15d-15(e) of the Exchange Act) as of the end of the period covered by this report. The purpose of disclosure controls is to ensure that information required to be disclosed in our reports filed with or submitted to the SEC under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls are also designed to ensure that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of March 31, 2021.
Changes in Internal Control Over Financial Reporting
There have not been any changes in our internal control over financial reporting as defined in Exchange Act Rules 13a-15(f) and 15d-15(f) that occurred during the quarter ended March 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
