Macquarie Asset Management ("MAM"), on behalf of the Macquarie Asia Infrastructure Fund 2 ("MAIF2"), announces the sale of DIG Airgas to Air Liquide, which successfully completed on 13 January. DIG Airgas is a leading industrial gas provider in South Korea, operating a nationwide network of air separation units and on‑site generators that supply essential gases to blue‑chip customers across petrochemical, semiconductor, display and other advanced manufacturing sectors. This transaction marks one of the largest M&A deals in South Korea in 2025, and represents MAM's biggest transaction in the country to date.
Since acquiring DIG Airgas in 2020 on behalf of its managed fund, MAM has focused on creating long term value by strengthening the company's position in South Korea's industrial gas market, scaling its operation and, diversifying its customer base into high‑growth sectors like semiconductors and secondary batteries. Over this period, DIG Airgas expanded from an initial pipeline of 20 projects to 80, driven by proactive asset management and strong customer engagement, particularly within fast‑growing semiconductor clusters. DIG Airgas also prioritised improvements in operational efficiency, cost optimisation, product diversification and a stronger capital structure through refinancing. Its sustainability performance also advanced through energy‑efficiency initiatives and a 25‑year, 50MW renewable power purchase agreement (PPA), achieving a GRESB1 score of ~100 and five‑star ratings in 2023-2025.
