Commenting on the 1^st quarter of 2026, François Jackow, Chief Executive Officer of the Air Liquide Group, stated:

“In a context of geopolitical instability, marked in particular by the conflict in the Middle East, where the safety of our teams and the integrity of our facilities have been our top priority, we delivered another strong performance during the quarter.

Our resilient and agile business model is the key to our continued growth. It is now more relevant than ever to address the growing challenges, whether industrial or energy, to sovereignty.

Specifically, our sales in the first quarter amounted to nearly 6.8 billion euros, up +3.4% excluding currency and energy, including the contribution from the acquisition of DIG Airgas¹. This growth was notably driven by the Gas & Services businesses, which recorded a +2% increase on a comparable basis. Geographically, the Americas have been the most dynamic region. In terms of businesses, Industrial Merchant (+3%) and Electronics (+3%) were solid growth drivers. Furthermore, Healthcare, which remains once again independent of broader industrial cycles, demonstrated notable strength with sustained growth (+4%).

At the same time, strengthening our operating performance and the ongoing transformation program enabled us to generate 142 million euros of efficiencies, up +8% compared to the same period in 2025. We have also actively managed our portfolio of businesses and adjusted our prices in Industrial Merchant which are up by +3.4%. These actions contributed to our total margin improvement target of +560 basis points excluding the energy impact over the 2022-2027 period. Furthermore, our cash flow from operating activities before changes in working capital has risen sharply, up +7% at constant exchange rates.

Finally, we remain committed to future-focused strategic investments. Our investments decisions during the period therefore totaled 1.5 billion euros, reaching new heights in industrial projects in particular. Our backlog, now at 5.5 billion euros, set a new record. These investments are part of several commercial successes we are proud to have achieved: in the United States, we will be supplying the new joint-venture between Hyundai Steel and Posco with industrial gases essential for its future low-carbon steel plant in Louisiana. In Electronics, we are going to support a world leader in semiconductors, in Japan, with ultra-pure gases for the production of next-generation AI chips. This growth momentum has also taken shape in South Korea, through the successful acquisition of DIG Airgas, which was completed ahead of schedule¹: this value-creating operation positions us at the heart of a dynamic and innovative economy, and has already opened the door to promising new projects.

Air Liquide is therefore confident in its ability to increase its operating margin by +100 basis points² and to deliver recurring net profit growth, at constant exchange rates in 2026³.

The Group is also confident in its ability to improve its margin by +100 basis points⁴ again in 2027. This brings its total objective to +560 basis points over the 2022-2027 period.”

Highlights

Corporate

• Completion of the DIG Airgas acquisition, a leading player in the industrial gases sector in South Korea, for approximately 3 billion euros. The Group will double its workforce in the country and achieve approximately 900 million euros in revenue. Completed ahead of schedule, this acquisition contributes to the Group’s overall performance earlier than expected.
• Successful inaugural multi-tranche bond issued in Swiss Francs, totaling 640 million CHF, to support Air Liquide’s long-term growth.

Industry and Decarbonization

• In Belgium, signature of an agreement to develop a carbon capture solution for Holcim’s near-zero cement plant in Obourg. This project, intended to capture 1.1 million metric tonnes of CO₂ per year, is part of Holcim’s GO4ZERO project aiming for carbon neutrality in Belgium by the end of the decade, and would contribute to the European Union’s net zero objective for 2050.
• In the United States, Airgas continues to contribute to the advancement of space exploration. As part of the Artemis II mission, the subsidiary supplied NASA with high-pressure nitrogen, which was essential for this historic launch. The space sector is one of the Group’s many areas of development, and where it is ideally positioned, particularly due to its long-standing presence in the United States.
• Signature of a long-term agreement with Hyundai-Posco Louisiana LLC (HPLS) to supply oxygen, nitrogen and argon to its future low-carbon steel plant in Louisiana, United States. The Group plans to invest more than 350 million USD in this project, which will also strengthen its presence in the country.

Electronics

• In Hiroshima, Japan, a new investment of 200 million euros to build, own and operate two state-of-the-art industrial gas production units. This project aims to support a world leader in semiconductors in the manufacture of next-generation chips, playing a key role in Artificial Intelligence technologies. With 78 dedicated units to electronics customers in Japan, Air Liquide is one of the market leaders.
• In Taiwan, inauguration of an Advanced Materials production plant in the city of Taichung. Already present in this strategic and innovative market with 54 dedicated units to the semiconductor industry in Taiwan, this is Air Liquide’s first large-scale production center for advanced deposition and etching materials in Taiwan. These molecules are essential to the development of next-generation chips, engines of artificial intelligence and high-performance computing.

Group revenue stood at 6,786 million euros in the 1^st quarter of 2026, up +3.4% excluding currency and energy impacts, including the contribution of the DIG Airgas acquisition.

On a comparable basis, sales grew by +1.9% compared to the 1^st quarter of 2025. The Group's published sales posted a decline of -3.5% in the 1^st quarter of 2026, impacted by unfavorable currency (-5.9%) and energy (-1.0%) impacts, partially offset by a significant scope impact of +1.5%.

Gas & Services revenue reached 6,595 million euros, up +1.9% in comparable growth⁵. Published Gas & Services revenue was down by -3.4% in the 1^st quarter of 2026, impacted by unfavorable currency (-5.9%) and energy (-1.0%) impacts, partially offset by a significant scope impact of +1.6%.

Industrial Merchant sales grew by +2.7% in the 1^st quarter, supported notably by a strengthening price effect (+3.4%). Gas volumes were resilient and those of hardgoods continued to improve in the United States. Large Industries activity (-0.9%) was contrasted: the very strong demand on the pipeline networks of the US Gulf Coast almost fully offset weak demand in Europe and Asia. Healthcare, whose growth is disconnected from industrial trends, posted a solid and steady increase in its revenue (+4.0%), balanced between Medical Gases and Home Healthcare. Finally, in Electronics (+2.9%), the +9% sales growth in Carrier Gases offset less dynamic business segments. Revenue growth excluding Equipment & Installation sales stood at +5%.

• Americas Gas & Services revenue reached 2,591 million euros in the 1^st quarter of 2026, up +5.5%. Large Industries (+8.3%) benefited from very strong demand from customers connected to the air gases and hydrogen pipeline networks in the United States. In Industrial Merchant, revenue grew by +5.3%, supported by a high price effect of +5.0% and resilient volumes. The strong sales growth in Healthcare (+6.6%) was notably driven by higher Medical Gases pricing in the region and the development of Home Healthcare in Latin America. In Electronics (-3.7%), the significant growth of more than +10% in Carrier Gases sales did not offset the decline in Equipment & Installation sales.
• Europe, Middle East & Africa revenue stood at 2,687 million euros and remained stable (-0.4%) compared to the 1^st quarter of 2025. In Large Industries (-3.0%), revenue was mainly impacted by the decline in hydrogen sales and the low activity of cogeneration units. Industrial Merchant sales were slightly down (-1.1%) but stable excluding exceptional rare gases sales recorded in the 1^st quarter of 2025. Sales growth remained strong (+4.3%) in Healthcare, notably in Medical Gases and Home Healthcare.
• Asia Pacific region revenue stood at 1,318 million euros. With the acquisition of DIG Airgas in South Korea completed in January 2026 ahead of schedule, it grew strongly by +8.3%, and remained stable (-0.7%) in comparable growth compared to the 1^st quarter of 2025. In Large Industries (-4.2%), activity remained overall weak. Industrial Merchant activity (-1.5%) was contrasted by country: sales were down in Japan but increased in South Korea and in China excluding helium sales. Electronics revenue grew strongly (+5.3%), particularly Carrier Gases and Advanced Materials sales.

Consolidated revenue of the Engineering & Technologies business reached 190 million euros and remained stable (+0.1%) compared to the 1^st quarter of 2025. The increase in technological equipment sales, particularly Turbo-Brayton LNG reliquefaction units, offset the decline in external Engineering sales. Indeed, within the Engineering & Technologies business, Engineering & Construction resources are primarily allocated to internal projects, notably in Large Industries and Electronics. Order intake for Group projects and third-party customers stood at 477 million euros.

Cash flow from operating activities before changes in working capital stood at 1,613 million euros, stable (-0.4%) compared to the 1^st quarter of 2025. It was up +6.7% excluding the currency effect and the impact related to the integration of DIG Airgas was very limited.

In the 1^st quarter of 2026, industrial and financial investment decisions reached a very high level of 1.5 billion euros. Finalized in mid-January 2026, the strategic acquisition of DIG Airgas in South Korea was added to investment decisions for an amount of approximately 3 billion euros. The investment backlog reached a new record of 5.5 billion euros, up from 4.9 billion euros at the end of 2025. The 12-month portfolio of investment opportunities remained at a high level of 4.5 billion euros.

Volumes were up in the Construction, Fabrication, and Electronic Assembly markets. Finally, the consolidation of bolt-on acquisitions also contributed to growth.
• In Healthcare, sales posted a strong growth of +6.6% which included a high price effect of +5.9%. In the Medical Gases business, the price effect remained very strong in Latin America and the United States, notably in proximity care where Intelli-OX is being rolled out, an innovative cylinder with a digital gauge that provides caregivers with a direct reading of the remaining oxygen consumption time. In Home Healthcare, sales grew strongly in Latin America, with the business benefiting from the increase in the number of patients and a high price effect.
• In Electronics (-3.7%), Equipment & Installation sales were compared to a very high level in early 2025, which masked the dynamic growth in the rest of the business, notably a growth of more than +10% in Carrier Gases sales.

Americas

• Historic launch of the Artemis II mission: As part of a long-standing collaboration between Air Liquide and NASA spanning more than 50 years, Airgas supplied the critical high-pressure nitrogen essential for the launch of NASA's Artemis II mission. The first manned flight of the Artemis program, this ten-day journey sent a crew of four into orbit around the Moon, marking the first travel into lunar space in over 50 years. The space sector is one of the Group's many areas of development, benefiting from an ideal positioning, notably due to its historical footprint in the United States.
• Investment of 350 million dollars in the United States: Air Liquide has entered into a long-term agreement to supply oxygen, nitrogen and argon to Hyundai-Posco Louisiana LLC (HPLS) for its new landmark low-carbon steel plant located in Louisiana, United States. Through this new infrastructure, the Group supports the development of a local and low-carbon production of essential materials for the US market. This partnership highlights Air Liquide's ability to support its customers in their international growth, while contributing to the relocation of American industry.

Completed ahead of schedule, this acquisition contributes to the Group's overall performance earlier than expected.

Engineering & Technologies

Consolidated revenue of the Engineering & Technologies business reached 190 million euros and remained stable (+0.1%) compared to the 1^st quarter of 2025. The increase in technological equipment sales, particularly Turbo-Brayton LNG reliquefaction units, offset the decline in external Engineering sales. Indeed, within the Engineering & Technologies business, Engineering & Construction resources are primarily allocated to internal projects, notably in Large Industries and Electronics.

Order intake for Group projects and third-party customers stood at 477 million euros. They included in particular air separation units for a major project in Electronics in Japan and for a low-carbon steel plant in Large Industries in the United States, Turbo-Brayton units, gas distribution equipment for Electronics, hydrogen filling stations as well as equipment for the aeronautics and space industry.

Investment cycle

INVESTMENT DECISIONS AND INVESTMENT BACKLOG

In the 1^st quarter of 2026, industrial and financial investment decisions reached a very high level of 1.5 billion euros. Finalized in mid-January 2026, the strategic acquisition of DIG Airgas in South Korea was added to investment decisions for an amount of approximately 3 billion euros.

Industrial investment decisions stood at a record level of 1,481 million euros and compared to 1,019 million euros in the 1^st quarter of 2025.

The Group consolidates its leadership position in Electronics by winning several long-term contracts with major customers in the semiconductor industry. These include in particular an investment of 200 million euros in Japan in two ultra-pure nitrogen, oxygen and argon production units allowing the manufacturing of advanced chips for Artificial Intelligence. In Large Industries, Air Liquide will invest more than 350 million US dollars in an air separation unit to supply Hyundai-Posco Louisiana Steel LLC (HPLS)⁶ new low-carbon steel plant under a long-term contract. This new capacity will be connected to the pipeline network in Louisiana and will also supply an existing customer, Koch Methanol, whose air gases needs are growing. This major project contributes to the relocation of industrial production capacities in the United States. In Industrial Merchant, the Group has decided to invest in several on-site production units in various Asian countries, notably to serve the semiconductor assembly market.

Financial investment decisions, excluding the DIG Airgas acquisition, included three bolt-on acquisitions for 38 million euros in Industrial Merchant and Healthcare in the United States and China.

The investment backlog reached a new record of 5.5 billion euros, up from 4.9 billion euros at the end of 2025. It consists of a diversified portfolio of around 75 projects, well-balanced between Large Industries and Electronics, mainly in Asia, Europe and to a lesser extent in the Americas.

START-UPS

The main start-ups in the 1^st quarter of 2026 include:

• in the Electronics business, carrier gases units in China,
• in Large Industries, the electrification of an air separation unit in Argentina.

INVESTMENT OPPORTUNITIES

The 12-month portfolio of investment opportunities remained at a high level of 4.5 billion euros. It remained stable despite a record level of decisions in the 1^st quarter, reflecting a strong dynamic in the development of new projects. Projects for Electronics customers represented approximately 40% of the portfolio and those related to the energy transition about one-third of the opportunities. The projects were mainly located in the Americas, Asia, and to a lesser extent in EMEA.

The total portfolio of opportunities, also including opportunities beyond 12 months, remained stable, exceeding 10 billion euros.

Operating Performance

The Group confirms its operating margin improvement⁷ ambition. It was revised upwards in February 2026, to +560 basis points over the six-year period, 2022-2027, supported by the three levers of pricing management, efficiencies, and business portfolio optimization.

• The price effect in the Industrial Merchant business stood at +3.4% in the 1^st quarter of 2026, slightly up compared to the 4^th quarter of 2025.
• Efficiencies⁸ amounted to 142 million euros, a record level for a 1^st quarter. They increased strongly by +8.3%, adding to a +17.4% increase in the 1^st quarter of 2025. The Group's transformation program actively contributes to these efficiencies, notably the rationalization of the organization, the restructuring of certain activities mainly in Europe in the 1^st quarter, and the deployment of integrated digital tools to optimize production and the supply chain. Procurement and the transverse continuous improvement program, notably consisting of more than a thousand industrial efficiency projects, also support these efficiencies. The reduction in headcount (excluding the significant scope impact) since the beginning of 2024 makes it possible to generate savings on personnel expenses.
• Business portfolio management continued in the 1^st quarter of 2026 with the major acquisition of DIG Airgas in South Korea, three bolt-on acquisitions in Industrial Merchant and Healthcare in the United States and China, and the divestiture of two Home Healthcare businesses in Europe.

Cash flow from operating activities before changes in working capital stood at 1,613 million euros, stable (-0.4%) compared to the 1^st quarter of 2025. It was up +6.7% excluding the currency effect and the impact related to the integration of DIG Airgas was very limited.

Bond issue

• Air Liquide completed a new bond issue in Swiss Francs (CHF) for a total amount of 640 million CHF. Carried out under the Group's Euro Medium Term Note (EMTN) program, this transaction is divided into three tranches with maturities of 5, 8 and 12 years, at a weighted average interest rate of less than 1.00% per annum.

Sustainability

• Air Liquide confirms the effectiveness of its voluntary low-carbon electricity sourcing program, a core lever of its Climate Transition Plan, delivering tangible results. Low-carbon electricity represents more than 40% of the electricity purchased by the Group. 2025 was marked by the start-up of 3 TWh per year from multi-year Power Purchase Agreements (PPAs), supporting the Group's long-term decarbonization trajectory. Since 2020, as part of its Climate objectives, the Group has signed PPAs representing a total annual reduction in CO2 emissions of 3.5 million tonnes, with a full ramp-up expected by 2027. This approach is complemented by the electrification of the few air separation units not yet electrified.

Outlook

In a context of geopolitical tensions in the Middle East, the Group's direct financial exposure in the region is very limited and represents approximately 1% of total revenue. The safety of employees remains an absolute priority. Local teams ensure the continuity of operations in order to maintain critical supplies of medical oxygen and nitrogen. The interruption of the helium source in Qatar since March has had a limited impact on the Group's performance in the first quarter, but the evolution of the situation remains a watch point for the coming months.

The acceleration of several underlying trends favorable to Air Liquide is one of the positive outcomes of this geopolitical context: customers' arbitration on the loading rate of their plants worldwide, the industrial rebound in the United States, the reshoring of strategic activities, the enhanced role of hydrogen in energy sovereignty, and the increased value now placed on resilience. In the face of inflation, which represents a short-term challenge, the Group's ability to adjust prices enables it to protect margins and create value over the long term.

In this uncertain context, the Group relies on structural strengths: a strong geographic and sector diversification, local and global agility, the resilience of its business model and a strong culture of innovation. Thus, while generating performance today, the Group is actively preparing for the future, notably through:

• the accelerated completion of the DIG Airgas acquisition providing a 12-month contribution in 2026,
• the record level of the backlog following business successes,
• the Group's major transformation program which continues its deployment.

Building on this momentum, in 2026, Air Liquide is confident in its ability to increase its operating margin⁹ by +100 basis points and to deliver recurring net profit¹⁰ growth, at constant exchange rates.

To provide enhanced visibility on its long-term trajectory, the Group announced at the end of last February the introduction of a new objective for 2027 to improve the operating margin by +100 basis points excluding the energy impact. The cumulative ambition thus stands at +560 basis points, excluding the energy impact, over the six-year period, 2022-2027.

Finally, to present its new medium-term strategy, the Group will host a Capital Markets Day on October 1, 2026.

APPENDICES

1. Performance indicators

Performance indicators used by the Group that are not directly defined in the financial statements have been prepared in accordance with the AMF position 2015-12 about alternative performance measures.

The performance indicators are the following:

• Currency and energy impacts
• Currency, energy and significant scope impacts
• Comparable sales change
• Efficiencies

1.1 DEFINITION OF CURRENCY, ENERGY AND SIGNIFICANT SCOPE IMPACTS

Since industrial and medical gases are rarely exported, the impact of currency fluctuations on activity levels and results is limited to euro translation impacts with respect to the financial statements of subsidiaries located outside the eurozone. The currency impact is calculated based on the aggregates for the period converted at the exchange rate for the previous period.

In addition, the Group passes on variations in the cost of energy (electricity and natural gas) to its customers via indexed invoicing integrated into their medium and long-term contracts. This indexing can lead to significant variations in sales (mainly in the Large Industries Business Line) from one period to another depending on fluctuations in prices on the energy market.

An energy impact is calculated based on the sales of each of the main subsidiaries in Large Industries. Their consolidation allows the determination of the energy impact for the Group as a whole. The foreign exchange rate used is the average annual exchange rate for the year N-1. Thus, at the subsidiary level, the following formula provides the energy impact, calculated for natural gas and electricity respectively:

Energy impact =
Share of sales indexed to energy year (N-1) x (Average energy price in year (N) - Average energy price in year (N-1))

This indexation effect of electricity and natural gas does not impact the operating income recurring.

The significant scope impact corresponds to the impact on sales of all acquisitions or disposals of a significant size for the Group. These changes in scope of consolidation are determined:

• for acquisitions during the period, by deducting from the aggregates for the period the contribution of the acquisition,
• for acquisitions during the previous period, by deducting from the aggregates for the period the contribution of the acquisition between January 1 of the current period and the anniversary date of the acquisition,
• for disposals during the period, by deducting from the aggregates for the previous period the contribution of the disposed entity as of the anniversary date of the disposal,
• for disposals during the previous period, by deducting from the aggregates for the previous period the contribution of the disposed entity.

1.2 VARIATION EXCLUDING CURRENCY AND ENERGY, AND COMPARABLE SALES CHANGE

This refers to:

• the change in revenue for the period, excluding the currency and energy impacts described above;
• the change in revenue for the period, excluding the currency, energy and significant scope impacts described above.

It is calculated as follows:

(a) Includes mainly the significant scope impact of the DIG Airgas acquisition

1.3 EFFICIENCIES

Efficiencies represent a sustainable cost reduction resulting from an action plan on a specific project. Efficiencies are identified and managed on a per project basis. Each project is followed by a team composed in alignment with the nature of the project (purchasing, operations, human resources...).
