MIC REPORTS FOURTH QUARTER AND FULL YEAR 2021 FINANCIAL AND OPERATIONAL RESULTS

NEW YORK, Feb. 22, 2022

"Following the successful conclusion of the sales of our IMTT and Atlantic Aviation businesses, our continuing operations are composed principally of Hawaii Gas," said Christopher Frost, chief executive officer of MIC. "The ongoing approval process related to the proposed merger of the Company with an entity managed by Argo Infrastructure Partners, LP is proceeding as anticipated. We continue to expect to receive the remaining approval from the Hawaii Public Utilities Commission and to conclude the transaction in the first half of 2022."

"If the merger is concluded on or prior to July 1, 2022, unitholders will receive merger consideration of $3.83 per unit in cash," Frost added. "If the merger is concluded after July 1, 2022, unitholders will receive $4.11 per unit in cash."

"Our financial results from continuing operations in the fourth quarter and full year 2021 reflect a continued increase in the number of people visiting Hawaii and the resulting growth in gas sales by our Hawaii Gas business," said Frost.

Financial and Operational Results

MIC's ongoing businesses include Hawaii Gas and several smaller operations collectively engaged in efforts to reduce the cost and improve the reliability and sustainability of energy in Hawaii. These businesses generate revenue primarily from the provision of gas to commercial, residential, and governmental customers and the generation of power.

MIC's results from continuing operations in 2021 reflect improving conditions for its operations as the number of visitors to Hawaii recovers from COVID-induced lows. The number of visitors to Hawaii increased to approximately 65% of pre-pandemic levels for the full year. The increase in the number of visitors drove hotel occupancy and restaurant patronage higher and consequently gas sales by Hawaii Gas.
