Air Liquide’s acquisition of DIG Airgas

Lee & Ko successfully advised Air Liquide group, one of the world’s largest industrial gas suppliers, on its acquisition of DIG Airgas. This transaction, valued at approximately KRW 4.6 trillion, represents one of the largest deals announced in Korea in 2025. Far beyond a simple large-scale acquisition, the transaction encompassed a wide range of complex legal and structural issues, including analysis and review of the transaction structure and acquisition financing structures from the initial stages of the transaction, repayment mechanisms for existing shareholder loans and acquisition facilities, assessment of post-merger integration (PMI) matters, analysis and advising on commercial agreements and withholding tax issues on capital gains realized by foreign sellers. Lee & Ko further provided comprehensive legal services throughout the entire process of the transaction, including legal due diligence on DIG Airgas and its Chinese subsidiaries, review and negotiation of the definitive agreements, business combination report filing with the Korea Fair Trade Commission and other required regulatory approvals including recently enacted and precedent-setting filing required by the Korean government, as well deep involvement with the W&I insurance underwriting process. Notably, the deal is highly regarded for having reached a definitive agreement within approximately two weeks following the final bidding process and approximately within a week from the initiation of intensive negotiations, in which Lee & Ko’s proactive role and contributions were instrumental. This deal stands as one of the representative examples of Lee & Ko’s global M&A expertise, successful negotiations with a global infra fund leveraging Lee & Ko’s significant expertise in advising on global GP-led transactions, undisputed leading experience with industrial gas transactions, unwavering client dedication, and proven execution capability in bringing highly complex transactions to completion within an accelerated timeframe.
