• Acquisition’s strong industrial and market logic ideally positions company for future growth and long-term value creation

• More than $300 million in synergies identified, with the majority to be achieved within the next two to three years

• Air Liquide strengthens its global leadership in the industrial gas industry

Globally, the combined businesses will generate annual sales of more than €20 billion (more than $22 billion at current exchange rates [1] ), employ approximately 68,000 people around the world, and serve well over three million customers and patients.

Benoît Potier, Chairman and CEO of Air Liquide, said : “We are very pleased to have successfully closed our acquisition of Airgas, which will contribute to our strategy of profitable growth over the long term. There is strong industrial and market logic to this acquisition, which ideally positions Air Liquide for future growth. The two businesses are highly complementary, and the transaction extends our customer base through a unique, multi-channel distribution network and a nationwide presence in the U.S. Since founding Airgas some 30 years ago, Peter McCausland has successfully grown the business into one of the premier industrial gas companies in the U.S., and I would like to thank him for his leadership, dedication and achievements. This transaction represents significant value potential for all Air Liquide stakeholders, and it is an exciting day for the Group as we welcome our Airgas colleagues and together begin a new chapter in our history.”

Peter McCausland, Executive Chairman of Airgas , said: “Today’s history-making transaction is the culmination of more than 30 years of growth and value that we have steadfastly delivered to Airgas shareholders – it is a proud moment. The future is very bright for Airgas’ more than one million customers and our talented employees as we join Air Liquide’s unrivalled global footprint and strength in technology and innovation, while remaining committed to Airgas’ product offering, service model, and entrepreneurial culture. Thank you to our customers, shareholders, and associates for believing in the Airgas vision, just as I have, for all of these years.”

Under the terms of the merger agreement, first announced and unanimously approved by each company’s Board of Directors in November 2015, Airgas shareholders receive $143 in cash for each share of common stock of Airgas. In connection with the merger, the Airgas common stock has been delisted from the New York Stock Exchange. Airgas will operate as a subsidiary of Air Liquide within the company’s U.S. operations and, commercially, will go to market as Airgas, an Air Liquide company.

Strategic Rationale:

• There is strong industrial and market logic to this acquisition, which ideally positions the Group for future growth and long term value creation. It allows Air Liquide to expand in the U.S., the largest global market for industrial gases, and extends Air Liquide’s customer base by more than one million customers. The transaction will also create efficiencies in production and supply chain thanks to the complementary nature of the two businesses, and allows for potential volume growth using Airgas’ footprint to accelerate the deployment of Air Liquide’s new offerings and technologies. The acquisition also brings with it the most advanced multi-channel distribution network in the U.S., including e-commerce and telesales capabilities.

• The transaction is expected to generate significant synergies. Through active preparation work prior to the closing, more than $300 million of pre-tax industrial, administrative and volume growth synergies have been identified, the majority of which are targeted for delivery within the next two to three years, and are structured in detailed work plans.

• The combination represents significant value potential for all Air Liquide stakeholders, including shareholders, customers, and employees . The transaction will be accretive from year one of ownership. Air Liquide and Airgas together will deliver greater value, service and innovation to customers in North America and around the world by allowing Air Liquide to offer its leading production and innovation capabilities to a broader customer base. This combination also creates new opportunities for employees as part of a leading global organization that is ideally positioned for growth.

• The combination strengthens Air Liquide’s global leadership in the industrial gas business.

Air Liquide becomes the leader in North America, complementing number one positions in Europe, Middle East/Africa and Asia-Pacific. It will also be number one in Industrial Merchant, Large Industries and Electronics, and one of the key players in Healthcare.

Next Steps:

• Air Liquide will pursue and finalize sales of certain assets of the combined company in line with the divestiture process described in the U.S. Federal Trade Commission’s press release on 13 May 2016.
