Supplemental Materials

February 17, 2021

This presentation by Macquarie Infrastructure Corporation (MIC) is proprietary and all rights are reserved. Any reproduction, in whole or in part, without the prior written consent of MIC is prohibited.

This presentation is based on information generally available to the public and does not contain any material, non-public information. The presentation has been prepared solely for informational purposes. It is not a solicitation of any offer to buy or sell any security or instrument.

The presentation is qualified in its entirety by disclosures made in MIC's Form 10-K filed with the SEC on February 17, 2021, and other materials filed with the SEC subsequently.

Forward-Looking Statements

This presentation contains forward-looking statements including regarding the anticipated specific and overall impacts of the COVID-19 pandemic. Forward-looking statements in this presentation are subject to a number of risks and uncertainties, some of which are beyond our control. Our actual results, performance, prospects or opportunities could differ materially from those expressed in or implied by the forward-looking statements. A description of known risks that could cause our actual results to differ appears under the caption "Risk Factors" in our Form 10-K filed with the SEC on February 17, 2021, and other materials filed with the SEC subsequently. Additional risks of which we are not currently aware could also cause our actual results to differ. These forward-looking statements are made as of the date of this presentation. We undertake no obligation to publicly update or revise any forward-looking statements whether as a result of new information, future events or otherwise, except as required by law.

With respect to the Company's guidance for EBITDA and Free Cash Flow in 2021, a reconciliation of EBITDA to net income (loss), the most comparable GAAP measure and a reconciliation of Free Cash Flow to cash from operating activities, the most comparable GAAP measure, are not available without unreasonable effort due to the Company's limited visibility into and inability to make accurate projections and estimates of items including management fees, hedging agreements, depreciation and any (benefit) provision for income taxes. These items may vary greatly from year to year and could significantly impact MIC's results as reported in accordance with GAAP.

"Macquarie Group" consists of Macquarie Group Limited and its worldwide subsidiaries and affiliates.

MIC is not an authorized deposit-taking institution for the purposes of the Banking Act 1959 (Commonwealth of Australia) and its obligations do not represent deposits or other liabilities of Macquarie Bank Limited ABN 46 008 583 542. Macquarie Bank Limited does not guarantee or otherwise provide assurance in respect of the obligations of MIC.

Use of Non-GAAP Metrics

In addition to our results under U.S. GAAP, we use certain non-GAAP measures to assess the performance and prospects of our businesses. In particular, we use EBITDA excluding non-cash items and Free Cash Flow.

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 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.

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.

Please review our Form 10-K and earnings release, filed on February 17, 2021, for a complete discussion of our use of non-GAAP metrics and any of our Form 10-K, earnings release or the appendix to this document for reconciliations of non-GAAP measures to the most comparable GAAP measures.

4Q20 Regional FAA Activity

Atlantic Aviation has seen continued year-over-year outperformance in the Inter-mountain West and Florida regions; business-oriented locations near city-centers have seen some recovery but generally continue to lag the portfolio

Year-Over-Year General Aviation Activity:

• • The outbreak of COVID-19 resulted in a decline in general aviation flight activity of approximately 80% year-over-year in April 2020 - Flight activity rebounded to down 18% in 4Q20 and down 15% in December 2020 at airports on which Atlantic Aviation operates, supported by the holiday period

  Up > 10%(10%) to 10%

  (30%) to (10%)Down > (30%)

• • The successful rollout of COVID-19 vaccines, both domestically and internationally, is expected to result in a further recovery of general aviation flight activity in 2021 to levels comparable with 2019 activity by year end - The most significant impact is expected to be on locations dominated by business activity historically
