About Macquarie Infrastructure Corp

Macquarie Infrastructure Corp (MIC) was a U.S.-based infrastructure company historically listed on the NYSE in the United States, with a corporate history marked by major portfolio simplification and a later take-private transaction. The company’s predecessor, Macquarie Infrastructure Company LLC, was formed in 2004 and MIC was converted into a Delaware corporation in 2015. SEC filings identified its principal executive offices at 125 West 55th Street, New York, NY 10019, reflecting a New York headquarters footprint tied to the wider Macquarie platform.

Its historical reportable businesses included IMTT, a bulk liquid terminal network; Atlantic Aviation, which provided fuel, terminal, hangar and related services to general aviation aircraft across airports in the U.S.; and Hawaii Gas, a regulated gas utility and energy distribution business in Hawaii. Over time, the company materially reshaped its portfolio: IMTT was sold in late 2020, and by early 2022 MIC stated that its continuing operations were composed principally of Hawaii Gas. That left the company much more concentrated than in its earlier diversified form.

Atlantic Aviation operated in a specialized general-aviation services niche, while Hawaii Gas served a geographically isolated market with utility-like characteristics. After the asset sales, however, MIC’s business mix became less balanced, increasing sensitivity to regulatory outcomes, operating execution and capital-allocation decisions at the remaining business.

MIC completed the sale of IMTT in December 2020, continued its corporate restructuring in 2021, and then announced in July 2022 that it had completed a merger with an affiliate of Argo Infrastructure Partners, LP, after which MIC units were delisted from the NYSE. In practical terms, that means the name “Macquarie Infrastructure Corp” is best understood today as a legacy NYSE issuer and infrastructure platform rather than a broadly traded active listed company.
