Group revenue stood at 27,058 million euros in 2024 and posted comparable(1) growth of +2.6% compared to 2023, identical in the 1st and 2nd half-year. The contribution of Argentina to comparable growth was +1.9% (down in the 4th quarter to +1.2%). The Group's published revenue decreased by -2.0%, impacted by unfavorable currency (-2.4%) and energy (-2.2%) impacts. There was no significant scope impact in 2024.
Gas & Services revenue reached 25,810 million euros in 2024, up by +2.7% on a comparable basis (including a contribution of +1.9% from Argentina). Published revenue in the Gas & Services businesses was down -2.1%, penalized by unfavorable currency (-2.5%) and energy (-2.3%) impacts. There was no significant scope impact in 2024.
All Gas & Services business lines grew. Revenue from Large Industries posted an increase of +1.2%, supported by the start-up of two large units at the beginning of the year but impacted by the divestiture of a cogeneration unit in Europe in early January 2024 and by numerous customer maintenance turnarounds. The development of the Industrial Merchant business (+1.6%) continued in 2024, illustrating the resilience of the business model in a difficult economi c environment: a solid price effect of +4.0% offset a marked decline in Hardgoods in the United States and slightly lower gas volumes. Sales of Electronics increased by +3.3%, supported by all business segments with the exception of Specialty Materials. The Healthcare business (+8.6%), independent of the industrial context, was the first contributor to growth; it benefited from the dynamic development of Home Healthcare, and the increase in volumes and prices of medical gases in an inflationary environment, particularly in Latin America.
Global Markets & Technologies posted a -2.5% decrease in revenue on a comparable basis, to 836 million euros in 2024. Excluding the divestiture of the technological activities for the Aeronautics sector in the 1st quarter, revenue from the business increased compared to 2023. Order intake for Group projects and third-party customers amounted to 775 million euros in 2024.
Consolidated revenue from Engineering & Construction totaled 412 million euros in 2024, an increase of +5.8%. Consolidated revenue excludes internal projects, in particular for Large Industries and Electronics, which are growing. Order intake for the Group and third-party customers reached a record level of 1,804 million euros in 2024.
The Group's operating income recurring (OIR) reached 5,391 million euros in 2024, an increase of +6.4% as published. Excluding the currency impact (on a comparable basis), it increased by +10.7% (and +6.8% excluding Argentina), which is significantly higher than the comparable sales growth, highlighting a strong leverage effect. This performance reflects the progress of the action plan deployed around three levers: efficiencies, pricing management in particular in Industrial Merchant and a dynamic asset portfolio management. Thus, Efficiencies(3) reached a record level of 497 million euros in 2024, compared to 466 million euros in 2023. They significantly exceeded the annual target of 400 million euros in the Advance plan.
Excluding energy impact, the operating margin posted a record increase of +110 basis points (Argentina not contributing to this improvement). Thus, from 2022 to 2024, cumulated annual improvements in the operating margin excluding the energy impact reached +260 basis points. It is ahead of the target of +320 basis points over the 4-year period of the Advance plan (2022-2025). Indeed, communicated in March 2022, the ADVANCE plan’s initial ambition for improving operating margin was +160 basis points over 4 years from 2022 to 2025. In February 2024, it was revised upwards to +320 basis points, a doubling of the initial target.
In February 2025, the ambition for improving the margin excluding energy impact is raised for the second time, over a period extended by one year. It now stands at +460 basis points over a 5-year period, from 2022 to 2026.
Structural transformation actions of the Group, initiated in 2024, will continue to support the achievement of this new performance ambition. They are structured around four key areas, leveraging data: simplification of the organization, extension of business service centers, industrial and commercial initiatives.
