Commenting on sales in the third quarter of 2025, François Jackow, Chief Executive Officer of the Air Liquide Group , stated: "Air Liquide delivered another very solid performance, continuing its profitable growth trajectory. In line with the first half of the year and despite a difficult environment, our sales continue to increase, once again demonstrating the strength of our business model. Amounting to nearly 6.6 billion euros at September 30, 2025, our revenue was up +1.9% on a comparable basis (‑2.4% on a reported basis, reflecting a negative currency impact and lower energy prices, which were passed on to our customers). The Gas and Services businesses, which accounts for 97% of the Group's revenue, increased by +1.9% on a comparable basis , to reach 6,386 million euros. In an uncertain industrial environment, Healthcare and Industrial Merchant were growth drivers , up sharply by +5% and +3%, respectively, on a comparable basis. Geographically, the Americas stood out in particular with a +5% growth. Air Liquide also continued to improve its performance . At the end of September, the Group's efficiencies were at a record high of +23%. We also continued the dynamic management of our business portfolio, while adjusting our prices in Industrial Merchant thanks to our ability to create value for our customers. Our cash flow is very solid , increasing by +7% excluding currency impact. Paving the way for future growth, our investment momentum is particularly strong . Well diversified, our investment backlog is again at a record level of nearly 5 billion euros in this third quarter. Our investment decisions amounted to 0.9 billion euros , with major industrial projects supporting the energy transition , such as ELYgator, our 200 MW electrolyzer in the Netherlands , but also in Electronics & Semiconductors. New state-of-the-art industrial gas production units will be built in Dresden, Germany for a major player in this industry, driven by AI and sovereignty needs. In addition, our outlook includes our planned acquisition of DIG Airgas , a leading industrial gas company in South Korea. Beyond the dynamism and innovation that characterize the country's economy, this transaction will quickly create value, thanks to the high complementarity between our businesses and the nearly 20 projects already secured. It will therefore contribute to our net profit the year following its integration. In this context, Air Liquide is very confident in its ability to further increase its operating margin ( ) and to deliver 1 recurring net profit ( ) growth, at constant exchange rates in 2025. The Group also maintains its ambition to increase 2 its operating margin by +460 basis points cumulated over five years to end-2026 (1) ." 2 Recurring net profit excluding exceptional and significant transactions that have no impact on the operating income recurring. 1 Excluding energy passthrough impact.

Q3 2025 activity report – Air Liquide Group revenue ( ) stood at 6,599 million euros in the 3 rd quarter 2025, a comparable growth of +1.9% compared to the 3 3 rd quarter 2024. This growth continued in line with the 1 st half of the year, benefiting from the resilience of the business portfolio in a complex environment. The Group's published revenue was down -2.4% , impacted by an unfavorable currency impact (-4.2%), with the energy impact being neutral (-0.1%). There was no significant scope impact in the 3 rd quarter 2025. Gas & Services revenue in the 3 rd quarter 2025 reached 6,386 million euros , up by +1.9% on a comparable basis. Sales growth for the Industrial Merchant business stood at +2.7% ( ) in the 3 rd quarter: it benefited from a price effect 4 of +3.1% which continues to strengthen, and improving volumes, particularly for Hardgoods, supported by the consolidation of bolt-on acquisitions. Revenue for Large Industries was stable ( -0.2% (4) ), with the contribution from the start-up and ramp-up of units offsetting weak demand, particularly in Europe and Asia. The slight decline in Electronics sales ( -0.9% ) does not reflect the dynamic growth of the business excluding Equipment & Installation sales (+5.9%). The latter are indeed more cyclical and are normalizing after reaching a record level in 2024. Finally, the Healthcare business, whose growth is disconnected from industrial trends, posted sustained revenue growth ( +4.9% ), particularly in Home Healthcare and Specialty Ingredients. ■ Gas & Services revenue in the Americas stood at 2,548 million euros in the 3 rd quarter 2025, up by +4.8% ( ) . 5 Sales growth for Large Industries (+5.2% (4) ) benefited from recent start-ups of new production units and resilient demand. In Industrial Merchant, revenue increased by +4.7% (4) , supported by a very solid price effect of +4.5%, resilient gas volumes, and by the contribution of bolt-on acquisitions, while volumes for hardgoods are improving but remain down compared to the 3 rd quarter 2024. Strong sales growth in Healthcare (+9.3%) was mainly driven by a strong price effect in the Medical Gases business in the United States and by the development of Home Healthcare in Latin America. In Electronics (-3.8%), the significant decline in Equipment & Installation sales masked the dynamic growth of the rest of the business (+5.6%). ■ Revenue in the Europe Middle East & Africa region stood at 2,584 million euros , up slightly by +0.4% compared to the 3 rd quarter 2024. In Large Industries (-2.0%), sales were mainly impacted in Germany by weak demand and a customer shutdown for force majeure, and in Benelux by lower sales from cogeneration units. Sales were stable in Industrial Merchant (0.0%), supported by a solid price effect and resilient gas volumes, with the exception of Helium and liquid CO 2 . Sales growth remained strong (+4.3%) in Healthcare, particularly in Home Healthcare and Specialty ingredients. ■ Revenue in the Asia-Pacific region stood at 1,255 million euros in the 3 rd quarter 2025, down -0.8% compared to the 3 rd quarter 2024. In Large Industries, sales were slightly down (-0.6%), with the contribution from recent start-ups of new production units partially offsetting overall weak demand in the region. Industrial Merchant revenue (-0.8%) was impacted by the marked decrease in helium sales in China and by weak revenue in the rest of the zone, despite otherwise growing sales in China. The stability (+0.2%) of sales in Electronics masked dynamic growth of the business excluding Equipment & Installation sales (+6.3%), with in particular the start-up of seven new production units in Asia since the beginning of the year. Engineering & Technologies ( ) revenue stood at 212 million euros in the 3 rd quarter 2025, a comparable growth of 6 +1.7% . Industrial and financial investment decisions stood at 924 million euros in the 3 rd quarter 2025 and 3.2 billion euros at the end of September. The investment backlog remains above 4.0 billion euros and reaches a new record at 4.9 billion euros , up from 4.6 billion euros at the end of June 2025. The additional contribution to sales from ramp-ups and start-ups of units amounted to 233 million euros at the end of the 3 rd quarter. For the full year 2025, it is expected to be between 310 and 340 million euros. 6 This comparable growth excludes the scope impact related to the internal transfer of some GM&T activities to Industrial Merchant in the 1 st quarter 2025. See appendix. 5 Includes Argentina's contribution of +0.6%, down sharply compared to 2024. 4 Excluding an internal transfer of assets between Large Industries and Industrial Merchant in the United States 3 Unless otherwise specified, the revenue variations are all variations on a comparable basis, excluding currency, energy (natural gas and electricity) and significant scope impacts.

Q3 2025 activity report – Air Liquide Americas Gas & Services Q3 2025 Revenue ■ Large Industries revenue increased by +5.2% (11) in the 3 rd quarter 2025 despite an already high comparison basis in the 3 rd quarter 2024 (+11.6%). This growth was supported by the ramp-up of a major air separation unit started in February 2024 and by new hydrogen sales on the US Gulf Coast pipeline network. Customer maintenance turnarounds were also less numerous this quarter, which offsets weaker demand in the Refining sector. ■ The Industrial Merchant business posted sales growth of +4.7% ( )( ) in the 3 rd quarter 2025. This growth benefited 11 12 from a price effect of +4.5% which continues to strengthen, particularly in the United States following the increase in cylinder rental fees in certain regions. While gas volumes remained stable, supported in particular by bulk gases, volumes for hardgoods were still down but clearly improving. Volumes were mainly up in the Construction, Pharmaceutical, and Materials markets. Finally, the consolidation of bolt-on acquisitions also contributed to growth. ■ Healthcare sales showed very dynamic growth of +9.3% . In the United States, medical gases prices are up sharply, supported by the deployment of the Intelli-OX offer for proximity care and for hospitals. Intelli-OX is a cylinder with a digital gauge that gives caregivers a direct reading of the remaining oxygen consumption time. In Latin America, the number of patients treated at home continued to increase, supporting sales growth. ■ Electronics revenue was down -3.8% but showed very solid growth (+5.6%) excluding Equipment & Installation sales. Indeed, the strong growth in sales of Specialty Materials and Advanced Materials and the resilience of Carrier Gases were not enough to offset the decline in sales of Equipment & Installation, which are more cyclical and are normalizing after a record revenue in 2024. Americas ■ Air Liquide has concluded new agreements to supply hydrogen to two of the largest refiners in the United States . The Group will leverage its existing infrastructures with nearly 50 million US dollars in investments for strategic upgrades to its network and the integration of new compression and distribution equipment directly within its existing pipelines. Europe, Middle East & Africa (EMEA) Revenue in the Europe Middle East & Africa ( ) zone stood at 2,584 million euros , up slightly by +0.4% ( ) compared to 13 14 the 3 rd quarter 2024. In Large Industries (-2.0%), sales were mainly impacted in Germany by weak demand and a customer shutdown for force majeure, and in Benelux by lower sales from cogeneration units. Sales were stable in Industrial Merchant (0.0%) (14) , supported by a solid price effect and resilient gas volumes, with the exception of Helium and liquid CO 2 . Sales growth remained strong (+4.3%) in Healthcare, particularly in Home Healthcare and Specialty ingredients. 14 Includes in the 3 rd quarter 2025 a contribution to comparable growth from the GM&T transferred activities of -0.2% on Gas & Services revenue and -0.7% on Industrial Merchant revenue. 13 Includes Europe, the Middle East, Africa and India. 12 includes in the 3 rd quarter 2025 a contribution to comparable growth from the GM&T transferred activities of -0.2% on Gas & Services revenue and -0.3% on Industrial Merchant revenue. 11 Excluding the impact of an internal transfer of assets between Large Industries and Industrial Merchant in the United States.

Air Liquide – Q3 2025 activity report EMEA Gas & Services Q3 2025 Revenue ■ In the 3 rd quarter 2025, Large Industries revenue was down -2.0% . Hydrogen sales in Germany were down, impacted by weak demand and a customer shutdown for force majeure, whereas revenue in the 3 rd quarter 2024 had benefited from one-off sales. In Benelux, weak demand for steam penalized revenue from cogeneration units. Conversely, air gases revenue remained resilient across the entire zone and hydrogen sales were up in the Middle East. ■ In Industrial Merchant , sales were stable ( 0.0% ) ( ) . The price 15 effect remained solid at +1.5%, as the decline in the price of bulk gases (indexed to falling energy prices) was softened by the proactive increase in the price of packaged gases. Furthermore, volumes of bulk and packaged gases were resilient, with the exception of helium and liquid CO 2 . Volumes were growing in the Metallurgy, Utilities (water, waste, electricity), and electronic components & packaging sectors. ■ In the Healthcare business, sales increased by +4.3% in the 3 rd quarter. Home Healthcare continued its development, supported by the increase in the number of patients monitored, particularly for diabetes, sleep apnea and intensive care in community care centers in Germany. Sales of Specialty ingredients were also up sharply. Eu rope, Middle East & Africa ■ Air Liquide has reached a significant milestone by making the final investment decision and thus starting the construction of ELYgator , a 200 MW electrolyzer , in the port of Rotterdam, in the Netherlands . The Group will invest more than 500 million euros to build, own and operate the electrolyzer, which will notably supply TotalEnergies industrial platform under a long-term contract . This project strengthens the Group's leadership in clean hydrogen production and represents a major step forward in the decarbonization of European industry. ■ Air Liquide has won a long-term contract and will supply large volumes of high-purity gases directly to a major customer in the semiconductor industry , in the heart of the "Silicon Saxony", in Dresden, Germany . The planned investment of more than 250 million euros will be Air Liquide's largest in the electronics sector in Europe, thereby strengthening its leadership on the continent. ■ The Community of Madrid in Spain has selected Air Liquide to provide healthcare services to 70,000 patients living with respiratory diseases under a 5-year contract . The Group distinguished itself in particular through the operational excellence and efficiency of its digital and artificial intelligence solutions , designed to improve patient health outcomes and their quality of life at home, by optimizing the care pathway at the best cost for society. Asia-Pacific Revenue in the Asia-Pacific region stood at 1,255 million euros in the 3 rd quarter 2025, down -0.8% compared to the 3 rd quarter 2024, but up by + 1.0% excluding the more cyclical sales of equipment and installations in the Electronics activity. In Large Industries, sales were slightly down (-0.6%), with the contribution from recent start-ups of new production units partially offsetting overall weak demand in the region. Industrial Merchant revenue (-0.8%) was 15 includes in the 3 rd quarter 2025 a contribution to comparable growth from the GM&T transferred activities of -0.2% on Gas & Services revenue and -0.7% on Industrial Merchant revenue PAGE 8 / 19

Q3 2025 activity report – Air Liquide impacted by the marked decrease in helium sales in China and by weak revenue in the rest of the zone, despite otherwise growing sales in China. The stability (+0.2%) of sales in the Electronics activity masked dynamic growth of the business excluding Equipment & Installation sales (+6.3%), with in particular the start-up of seven new production units in Asia since the beginning of the year. Asia-Pacific Gas & Services Q3 2025 Revenue ■ Large Industries sales were slightly down by -0.6% in the 3 rd quarter 2025. The ramp-up of new units in China, notably the takeover from Wanhua at the end of 2024, and the supply of additional hydrogen volumes to the KMCI customer in South Korea under a long-term contract, were supporting growth, but overall growth was impacted by demand that remained weak in the region. ■ In Industrial Merchant , revenue contracted slightly, by -0.8% . The price effect (-0.5%) continued to improve in a low inflation context, but it remained impacted by the sharp decline in helium prices in China and CO 2 prices in Australia. In China, revenue growth continued despite a lower contribution from bolt-on acquisitions and the decline in helium sales. In the rest of Asia, sales trends were more mixed, with solid growth notably in Taiwan in secondary Electronics, but revenue was down in Japan and Australia. Volumes were mainly up in the Electronic components and packaging markets and the Automotive market. ■ Electronics sales were stable ( +0.2% ) in the 3 rd quarter, which did not reflect the dynamic growth (+6.3%) of the business excluding Equipment & Installation sales. Indeed, the double-digit growth in Carrier Gases sales continued in the 3 rd quarter, supported by the start-up of seven new production units in Asia since the beginning of the year. This growth was impacted by a decline in Equipment & Installation sales, which are more cyclical and are normalizing after reaching a very high level in 2024. Asia-Pacific ■ Air Liquide has started up a new Advanced Materials production plant in South Korea . It will supply Subleem TM , an innovative Advanced Materials offer from the Group, to key customers in the semiconductor sector. This offer includes a portfolio of very high-purity molybdenum-based molecules and proprietary distribution systems never seen before. Establishing itself as a promising alternative to tungsten, a traditional material for chip manufacturing, molybdenum is revolutionizing the sector and enabling the development of the most advanced next generations of memory and logic chips, driven by the acceleration of Artificial Intelligence applications. Through this strategic investment, Air Liquide confirms its technological leadership status by being the first industrial player able to supply molybdenum-based solutions in large quantities to its customers. ■ Under two new long-term contracts and for a total investment of 130 million euros , Air Liquide will build, own and operate two new Carrier Gases production facilities to support the expansion of a major semiconductor manufacturer in Singapore . Very high-purity gases are essential to support the next wave of digital technologies, including AI. These new contracts, signed just months apart, underscore the accelerating demand for advanced electronic components in this strategic market. PAGE 9 / 19

Q3 2025 activity report – Air Liquide Operating Performance The Group confirms its Operating margin improvement ( ) ambition despite the uncertain environment. It was 19 revised upwards in February 2025, to +460 basis points over 5 years until the end of 2026, supported by the three levers of price management, efficiencies, and business portfolio optimization. In the 3 rd quarter, in an inflationary environment, the Group is continuing its active price management . Thus, the price effect in the Industrial Merchant business stood at +3.1% and comes on top of the strong price increases already implemented since 2022. Efficiencies ( ) reached 163 million euros in the 3 rd quarter. They amounted to 434 million euros over the first 20 9 months of the year, a strong increase of +22.9% compared to the same period in 2024. They are already 15% higher than the total efficiencies achieved for the full year 2022. This performance confirms that the Group's transformation program has started to contribute to efficiencies. Procurement and the cross-functional continuous improvement program, consisting notably of more than a thousand industrial efficiencies projects, also support this performance. Furthermore, the decrease in headcount since the beginning of the year is generating savings on personnel costs. This strong increase in efficiencies contributes to the improvement of the operating margin by allowing in particular to offset certain unfavorable factors , such as the currency impact, or enabling the increase in investments . Over the first 9 months of the year, the Group continued the active management of its business portfolio by completing 8 acquisitions and 3 divestitures . These include six acquisitions in Industrial Merchant in the United States, China, Brazil, Spain, and Canada and two acquisitions in Home Healthcare in Germany. The Group also completed the divestiture of its activities in Nigeria in Industrial Merchant, and for Home Healthcare, in Japan, and in French Guiana. Cash flow from operating activities before changes in working capital stood at 4,947 million euros at the end of September, up by +6.8% excluding currency impact, and +4.5% as published. In the 3 rd quarter 2025, the Group recorded a non-recurring positive cash impact of 100 million US dollars. It corresponds to the recognition in the United States of a 100% tax depreciation for new projects and R&D spending, with a retroactive impact on the first 9 months of the year. Net debt stood at 9,317 million euros at the end of September, down by 477 million euros compared to 9,794 million euros at June 30, 2025. 20 See definition in appendices. 19 Excluding the energy impact.

Air Liquide – Q3 2025 activity report Outlook Air Liquide is and remains a growth company . The Group's growth is supported by four powerful drivers activated strategically depending on the market context and opportunities: - Optimization of the use of existing assets : this engine drives low-capex growth by maximizing value from the current asset base. It encompasses two primary levers: pricing and volume optimization. This serves as a reservoir of growth, particularly pertinent in the current environment of reduced volumes. In the 3 rd quarter 2025 , the Group concluded new agreements with two of the largest refiners in the United States and will leverage its existing infrastructures to supply them with hydrogen. - Investments in core business activities : leveraging the leading innovation and technology capabilities of the Group, this lever fuels growth through strategic investments in core operations. While Carrier Gases projects in Electronics are a major growth driver, significant growth investments continue to be made across Large Industries, Industrial Merchant, and Healthcare. In the 3 rd quarter 2025 , Air Liquide was selected to provide healthcare services to 70,000 patients living with respiratory diseases in the Community of Madrid in Spain. In the Electronics business, the Group won a long-term contract with a major customer in the semiconductor industry and will invest 250 million euros to supply large volumes of high-purity gases to its site in Dresden, Germany. In Singapore, Air Liquide announced an investment of 130 million euros to build, own and operate two new Carrier Gases production facilities for a major semiconductor manufacturer. - The energy transition : this growth engine extends beyond low-carbon hydrogen to include low-carbon oxygen like for the ExxonMobil project in the US, and comprehensive CO 2 management solutions. In the 3 rd quarter 2025 , Air Liquide announced an investment of more than 500 million euros to build, own and operate a 200 MW electrolyzer in Rotterdam in the Netherlands, to supply the TotalEnergies industrial platform in particular with low-carbon hydrogen under a long term contract. - Acquisitions : the final growth pillar encompasses both bolt-on and strategic acquisitions. In the 3 rd quarter 2025 , the Group announced the signing of an agreement for the strategic acquisition of DIG Airgas in South Korea. Furthermore, financial investment decisions notably include a bolt-on acquisition in the Industrial Merchant business in Canada. These four growth engines are supported by robust foundations . The Group’s healthy balance sheet allows financing of industrial and financial investments. Furthermore, the ongoing transformation program contributes to effectively lowering the cost structure of the Group to adapt to today's environment of reduced volume s. This transformation strengthens the Group's agility and allows for the optimal activation of the most appropriate growth drivers for market conditions and emerging opportunities. Quarter after quarter, Air Liquide stays the course and continues to achieve solid financial performance . The Group recorded a profitable growth in sales , once again demonstrating the strength of its business model , a source of growth and resilience . The operating margin continues to improve, in line with the ambition for an improvement of +200 basis points over two years (2025-2026) excluding the energy impact. In addition, the investment backlog achieved a new record high in the 3 rd quarter. Air Liquide stays the course. The Group confirms its ability to further increase its operating margin and to deliver recurring net profit ( ) growth at constant exchange rates in 2025. The Group also maintains its ambition to 21 increase its operating margin (21) by +460 basis points cumulated over five years to end-2026 21 Increase of the operating margin excluding energy passthrough impact. Recurring net profit excluding exceptional and significant transactions that have no impact on the operating income recurring. PAGE 14 / 19

Q3 2025 activity report – Air Liquide APPENDICES 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, energy and significant scope impacts ● Comparable sales change and comparable operating income recurring change ● Operating margin and operating margin excluding energy impact ● Recurring net profit Group share ● Recurring net profit excluding currency impact ● Net Profit Excluding IFRS16 ● Net Profit Recurring Excluding IFRS16 ● Efficiencies ● Return on Capital Employed (ROCE) ● Recurring ROCE D EFINITION OF C URRENCY , 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.
