What is the Wolf acquisition?
In 2024, Ariston completed the acquisition of Wolf Group, a leading German manufacturer of heating, ventilation, and air handling products. The acquisition expanded Ariston's presence in Germany and added ventilation and air handling capabilities to its portfolio.

Aristide Merloni founded the company in 1930 in Fabriano, Italy, originally producing scales and industrial products. The company pivoted to thermal comfort products, and in 1960 Ariston produced its first water heater, which became the foundation of the thermal comfort business.

The Merloni family built the company into one of Italy's leading industrial manufacturers through the 1960s and 1970s. The family also owned Merloni Elettrodomestici, a kitchen appliance business that was later renamed Indesit Company and acquired by Whirlpool in 2014. The thermal comfort business remained under Merloni family control as a separate entity.

Through the 1980s and 1990s, Ariston expanded internationally, establishing manufacturing and distribution operations across Europe. The company acquired regional brands including Chaffoteaux (France), Elco (Germany), and Racold (India) to build a multi-brand portfolio tailored to specific geographic markets.

In November 2021, Ariston Holding N.V. listed on Euronext Milan, separating the thermal comfort business from any remaining kitchen appliance operations. The IPO raised capital to fund growth investments, particularly in heat pump technology and renewable heating solutions.

In 2024, Ariston completed the acquisition of Wolf Group, a leading German manufacturer of heating, ventilation, and air handling products. The Wolf acquisition significantly expanded Ariston's presence in the German market and added ventilation and air handling capabilities to its portfolio.

Also in 2024, the Russian government transferred control of Ariston Thermo Rus LLC to an entity managed by Gazprom without notifying the company. Ariston subsequently deconsolidated its Russian subsidiary, impacting FY2024 financial results.

In FY2025, Ariston returned to a growth trajectory. Revenue reached EUR 2,707 million, up 3.0% organically, driven by strong performance in Europe, particularly heat pump sales in Germany. Adjusted EBIT margin expanded 100 basis points to 7.1%. Group net profit reached EUR 132.4 million, a significant recovery from EUR 2.5 million in FY2024.

Ariston Group has implemented sustainability initiatives focused on energy efficiency, renewable energy integration, and circular economy principles. The company's "Road to 100" ESG plan targets reducing CO2 emissions by 100 million tons through sustainable energy solutions and smart home products.

The company's environmental strategy centers on developing energy-efficient products that help consumers reduce their carbon footprint and energy costs. Ariston has invested significantly in heat pump technology, hybrid heating solutions, and solar thermal systems. The company has implemented energy efficiency programs across its manufacturing facilities and established environmental management systems.

The Russian government's expropriation of Ariston Thermo Rus LLC in April 2024 represents the most significant controversy. Russian authorities transferred control of the subsidiary to an entity managed by Gazprom without notifying Ariston. The Italian government and the European Union criticized the action. Ariston subsequently deconsolidated its Russian subsidiary, which impacted FY2024 financial results.

European regulatory pressure on gas boilers presents an ongoing challenge. The European Union's push to phase out gas boilers in favor of heat pumps requires Ariston to accelerate its product transition while managing declining gas boiler sales. Regulatory uncertainty regarding phase-out timelines affects product planning and investment decisions.

FY2024 financial performance was weak, with revenue declining 12.7% like-for-like due to weak European construction activity, the energy crisis impact on consumer spending, and the deconsolidation of the Russian subsidiary. The company returned to growth in FY2025 with 3.0% organic revenue growth.

Competition from Asian heat pump manufacturers including Daikin and Mitsubishi Electric is intensifying as the European heat pump market grows. Ariston must differentiate its offerings through brand strength, product quality, and installation network advantages.
