First Half Results: Outstanding H1 2021 performance

• increase in sales and operating margin
• strong investment portfolio
• numerous initiatives related to sustainable development

Commenting on the 1^st half of 2021, Benoît Potier, Chairman and CEO of Air Liquide, said:

'This first half excellent performance reflects the momentum of our markets and the acceleration in sales in the 2^nd quarter. These exceeded the level seen in 2^nd quarter of 2019⁽¹⁾, across all regions and for all activities. Sales for the half year were close to 11 billion euros, marking strong growth of +9.2% on a comparable basis, versus the 1^st half of 2020.

In Gas & Services, the rebound in industrial activities was particularly strong in the 2^nd quarter, both in Large Industries and Industrial Merchant. Electronics also recorded strong growth at the end of the half year. The Healthcare business line remained at a high level, with teams strongly committed to the fight against the pandemic. Geographically speaking, markets are growing in all regions, although some countries remain vulnerable to the pandemic situation.

Engineering & Construction and Global Markets & Technologies activities posted strong growth.

The Group's operating margin rose again sharply, by +100 basis points, excluding the energy impact. This improvement reflects the contribution of the structural margin improvement program, through ongoing recurring efficiency programs in the amount of 206 million euros, in line with the annual objective set at more than 400 million euros. It also illustrates the strong pricing policy, in particular in Industrial Merchant, active business portfolio management and is temporarily supported by the effects of the exceptional cost containment plan, which will diminish with the recovery in activity.

Net profit rose significantly by +14.9% to more than 1.2 billion euros. The cash flow to sales ratio also increased and reached 23%. The debt-to-equity ratio was down sharply versus the end of June 2020.

With almost half of the projects linked to the energy transition, 12-month investment opportunities are numerous and total 3 billion euros. Investment decisions for the half year were high at 1.9 billion euros, including the acquisition of the Sasol oxygen production plants in Secunda, South Africa. Solid, diversified and largely focused on the energy transition, the project backlog totaling 3.1 billion euros is particularly promising for future growth.

With a growth model combining financial performance with societal performance, Air Liquide is a major player in a sustainable future and is particularly committed to developing a low-carbon society through the reduction of CO2 emissions and the implementation of hydrogen solutions.

In 2021, in a context of recovery in the second half of the year, Air Liquide is confident in its ability to further increase its operating margin and to deliver recurring net profit growth⁽²⁾, at constant exchange rates.'

(1) Due to the exceptional impact of the pandemic in the 1^st half of 2020, a comparison with 2019 1^st half sales has been introduced for context in reviewing 1^st half 2021 performance. The comparisons between 2021 and 2019 (over the half year or over the quarter) are calculated by adding 2020 and 2021 comparable effects. They are given as a reference point and do not constitute an alternative performance measure.

(2) Excluding significant and exceptional items with no impact on recurring operating income. Excluding the impact of a possible US tax reform in 2021.

Group revenue for the 1^st half of 2021 totaled 10,846 million euros, up +9.2% on a comparable basis with the 1^st half of 2020 which was affected by the public health crisis. Sales posted strong comparable growth of +15.2% during the 2^nd quarter of 2021 and were up +6% versus the 2^nd quarter of 2019. Engineering & Construction consolidated revenue was up +65.9% in the 1^st half on a comparable basis and Global Markets & Technologies was up +34.9%. The Group revenue was up +5.6% as published in the 1^st half despite the strong negative currency impact (-4.8%) and significant scope impact (-2.8%), which were partly offset by the energy impact (+4.0%).

Gas & Servicesrevenue amounted to 10,350 million euros during the 1^st half, representing an increase of +8.0% on a comparable basis. All business lines enjoyed strong growth, and sales in the2^nd quarter of 2021 were higher than those in the 2^nd quarter of 2019 across all business lines and all regions. Sales as published for the 1^st half of 2021 were up by +4.3% despite the unfavorable currency impact (-4.9%) and significant scope impact (-3.0%), which were partially offset by the energy impact (+4.2%). The significant scope impact reflects the sale of Schülke in Healthcare and the reduction or sale of the Group's stakes in several non-strategic distributors in Japan. These sales will no longer have an impact during the 2^nd half of 2021.

• Gas & Services revenue in the Americas totaled 4,059 million euros, up +7.3% on a comparable basis with the 1^st half of 2020 which had been down -5.1%. In North America, all the business lines returned to a close or higher level in the 2^nd quarter than the same period in 2019. In Latin America, sales enjoyed strong growth in all business lines in the 1^st half. Across the Americas region, Large Industries revenue was up +7.7% on a comparable basis and Industrial Merchant revenue was up +6.1%. Healthcare sales increased by +16.9% driven by the medical oxygen demand and the pick-up in activity in proximity care and Home Healthcare. Electronics revenue was up +2.7%, thanks to the strong momentum of Carrier gases sales.
• Revenue in Europe amounted to 3,657 million euros and was up +7.4% on a comparable basis. Sales in industrial activities were higher than those in the 1^st half of 2019. Large Industries sales (+4.1%) enjoyed strong activity in the Steel and Chemicals sectors. Industrial Merchant sales were up +11.3% and reached a higher level than in the 1^st half of 2019. Healthcare (+6.4%) remains committed to fighting the pandemic and has seen a pick-up in the Home Healthcare business and surgical activities in hospitals.
• Sales in Asia Pacific increased by +8.7% on a comparable basis and totaled 2,326 million euros. All business lines and regions posted growth in the 1^st half of 2021, thanks to a favorable basis of comparison with the 1^st half of 2020 which was down -2.1% due to the public health crisis. Volumes were strong in Large Industries, which enjoyed an increase in revenue of +9.8%. The strong growth in Industrial Merchant sales (+12.3%) was mainly driven by high activity in China which posted double-digit volume growth compared with the 1^st half of 2019. In Electronics (+4.5%), Carrier gases contributed significantly to growth and benefited from the ramp-up of several units.
• Revenue in the Middle East and Africa region stood at 308 million euros, up by +18.9% on a comparable basis over the 1^st half.

In the 1^st half, Healthcare sales posted significant growth of +9.4% on a comparable basis, with the teams still fully committed to the fight against Covid-19. Large Industries revenue was up +7.3% thanks mainly to the contribution from new facilities and the strong demand from the Steel and Chemicals sectors. Industrial Merchant sales were up +8.5% driven by a pick-up in sales volumes, strong activity in China and a solid +1.9% pricing impact over the half year. Electronics sales increased by +4.7%, with Carrier gases sales driven by the ramp-up of new production units.

Engineering & Constructionconsolidated revenue were up +65.9% and stood at 169 million euros in the 1^st half of 2021. Order intake totaled 542 million euros, thanks to positive momentum in Asia and the energy transition.

Global Markets & Technologiessales totaled 327 million euros, with strong comparable growth of +34.9% supported notably by the biogas activity and high value added technological equipment sales.

Efficiencies^[1]totaled 206 million euros in the 1^st half, up +3.5% and in line with the annual target of more than 400 million euros. Moreover, the exceptional cost containment plan launched in response to the health crisis was extended and adapted to the gradual recovery in activity. The impact of these exceptional measures is expected to fall sharply during the 2^nd half, in line with the expected recovery in activity.

Group Operating Income Recurring (OIR) reached 1,948 million euros in the 1^st half of 2021, an increase of +7.4% and of +17.1% on a comparable basis, which is significantly higher than the comparable sales growth of +9.2% over the half-year.

The operating margin (OIR to revenue) stood at 18.0%, representing a marked improvement of +100 basis points excluding the energy impact compared with the 1^st half of 2020. Gas & services operating margin stood at 20.0%, a significant improvement of +120 basis points excluding the energy impact. On a reported basis, operating margin improvement was limited due to a significant increase in energy prices during the 1^st half of 2021, which was contractually passed through to customers and therefore had a dilutive impact on the published margin.

The net profit (Group share) amounted to 1,239 million euros in the 1^st half of 2021, an increase of +14.9% as published and +23.1% excluding the currency impact.
