About Macquarie Infrastructure Holdings, LLC

Macquarie Infrastructure Holdings, LLC is a United States-based infrastructure and energy-related company whose history is closely tied to the Macquarie platform and to the former NYSE-listed security MIC. From an investor’s perspective, it is important to note that the company is no longer an active NYSE/NASDAQ-listed equity; it was delisted after a merger completed in 2022. Its principal office was in New York, at 125 West 55th Street, and its current corporate form dates to 2021, when Macquarie Infrastructure Holdings, LLC became the successor to Macquarie Infrastructure Corporation, itself the successor to Macquarie Infrastructure Company LLC formed in 2004.

Historically, the portfolio included multiple infrastructure businesses, but over time the company became much more focused. By early 2022, management stated that continuing operations were composed principally of Hawaii Gas after the successful sales of the IMTT and Atlantic Aviation businesses. Hawaii Gas is a regulated gas utility business in Hawaii, giving the company a defensive profile compared with more cyclical infrastructure assets.

The 2021 reorganization simplified the legal structure and aligned the listed parent more closely with the underlying asset base. In 2022, the company announced the completion of a merger with an entity managed by Argo Infrastructure Partners, and the units were subsequently delisted from the New York Stock Exchange in July 2022. That sequence materially changed the investment case: rather than operating as a diversified public infrastructure vehicle, the platform moved toward private ownership and a narrower operating footprint. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1845290/000110465921118160/tm2128075d1_ex99-1.htm?utm_source=openai)) From a competitive standpoint, MIH’s appeal was never based on high-growth product innovation. Instead, it came from the scarcity value of infrastructure assets, regulatory barriers, and the resilience of demand for energy distribution and related essential services. The company’s geographic exposure was highly concentrated in the United States, with a particularly strong operational presence in Hawaii and corporate functions in New York. That concentration could support earnings visibility, but it also created meaningful dependence on local regulation, capital expenditure requirements, and the economics of a single-state utility footprint.

Any mention of SEC Form 4 insider transactions should therefore be interpreted in historical context, reflecting the period when the issuer was still subject to public-market reporting obligations. That makes the company relevant mainly for retrospective analysis of asset monetization, sponsor-led restructuring, and the lifecycle of a listed infrastructure platform in the United States.
