2025-07-22 After the binding agreement reached in February, the acquisition of Ambiente Energia, based in Schio in Vicenza, from the Marzotto Group, through subsidiary Herambiente Servizi Industriali, has been completed. This transaction further expands the offer of waste recovery and treatment services to companies in one of the most dynamic areas of the country centrata Acquisition signed after last February’s binding agreement This morning in Bologna, Herambiente Servizi Industriali, a subsidiary of Herambiente, finalised the acquisition, from Manifattura Lane Gaetano Marzotto & Figli of 100% of the capital of Ambiente Energia, a company operating in liquid industrial waste treatment at its plant in Schio, near Vicenza. This closing concludes the process that began on 27 February, when a binding agreement was signed by the two companies. Transaction in line with the 2028 Business Plan The Hera Group thus continues its growth in the North-East, in waste treatment and recovery in particular, fully consistent with its 2028 Business Plan, which sees vertical integrations as an important lever for further expansion and diversification of its plant base, with positive impacts on profitability and market share. More specifically, Ambiente Energia will extend Herambiente Servizi Industriali global waste management offer in one of the most productive and dynamic areas of the country, where the Hera Group is already established with its subsidiaries Vallortigara Servizi Ambientali with two plants in Vicenza province, Aliplast in the Treviso area and Recycla with two plants in Treviso and Pordenone. A multi-purpose plant with an annual capacity of over 120,000 tonnes Ambiente Energia plant, with an annual capacity of more than 120,000 tonnes, thanks to state-of-the-art technological equipment, treats numerous types of liquid and sludge waste, both hazardous and non-hazardous, such as, for example, water from painting and washing, acids and bases, and water from chemical-physical treatments. Its services are thus completely designed for the industrial districts of the Veneto region, including the textile, tanning, engineering and eyewear industries. The purification plant, which returns water to surface waters after treatment, has 41 storage tanks, a wastewater treatment line (both chemical-physical and biological) and a sludge treatment line. The industrial added value of the agreement This capacity will allow for greater flexibility and volume while constructing the waste management and recovery projects proposed by Herambiente Servizi Industriali to local companies. As for Ambiente Energia’s existing customers, they will gain access to the know-how of Herambiente and its subsidiaries in developing resource valorisation and circular economy projects, with a focus on the treatment of liquid and sludge waste. Full employment continuity for Ambiente Energia resources As was confirmed when the binding agreement was signed, the transaction foresees the retention of all of Ambiente Energia current employees, guaranteeing full employment continuity protecting the company’s technical-operational assets for the benefit of its customers. Ramonda: “positive spin-offs on cross-selling and synergies with neighbouring Vallortigara” “We are very pleased with this further growth we have achieved,” explains Herambiente CEO Andrea Ramonda. “This acquisition not only consolidates Herambiente’s already vast set of plants, but also further broadens the customer base in environmental services, with positive spin-offs on cross-selling opportunities, which will also benefit from synergies with the neighbouring Vallortigara Servizi Ambientali, already part of the Hera Group.” 20250722 - Hera Group acquires Ambiente Energia.pdf 11:25:00 sede Hera 110x150.jpg Download Press Release sede Hera 110x150.jpg

2025-07-17 centrata For 2022-2023, the Hera Group is once again among Italy’s top companies for the technical quality of its water service, as appears in the ranking recently published by the Regulatory Authority for Energy, Networks and the Environment (ARERA), which recognises the high standards achieved in infrastructure efficiency and service levels and confirms Hera’s presence in the top positions for the third consecutive two-year period, that is, since the ranking was established, with the Ferrara area ranking second. The significant results achieved in the various local areas, from Emilia-Romagna to the Triveneto and Marche regions, confirm the Hera Group as one of the country’s most virtuous operators and reward the improvement projects and the investments made over the years in the integrated water service: over 1 billion euros in the past five years, with a further acceleration planned in the coming years. In fact, 1.5 billion are the allocated resources for the five-year period 2024-2028, primarily aimed at increasing the efficiency and resilience of networks and plants, to cope with the increasingly frequent and intense extreme weather phenomena. One of the multi-utility's key strengths is its ability to combine the typical levers of a large industrial operator, such as significant investment and the use of innovative technologies, with strong local roots and ongoing dialogue with local institutions, which have distinguished the Hera Group since its inception. The stated goal is to foster the development of territories that are increasingly liveable for citizens, more competitive for businesses, and more resilient to meet the challenges of climate change. 26 total technical quality awards earned by the Hera Group ARERA, based on the evaluations carried out, gave the Hera Group 26 overall awards for the technical quality results achieved, a particularly significant achievement because it covers all of the managed territorial areas in 4 italian regions. Highly significant results were achieved with regard to reducing water losses in Bologna, Ferrara and Ravenna, while the Modena area and the Triveneto area were also awarded for the quality of purified water, with particular reference to the city of Trieste. The Group company AcegasApsAmga has received a double award for the parameter measuring performance in urban wastewater treatment: one for achieving the targets set for the 2022–2023 period, and a second, even more significant, for recording the highest percentage improvement at the national level compared to the previous two-year period. This recognition highlights the profound transformation of wastewater treatment system in Trieste, thanks to the Servola plant, a milestone of technological innovation, operational sustainability, and environmental vision. Six indicators to assess the technical quality of the service For the 2022-2023 two-year period, ARERA used six indicators to evaluate technical quality (i.e. the standards and technical performances that must be met to guarantee a high-quality and efficient service). For each, it identified annual maintenance or improvement objectives: leakage in aqueduct networks, service interruptions, drinking water quality, efficiency of the sewerage service, disposal of sewage sludge, and the quality of purified wastewater. The objective is to guarantee an efficient service, adequately meeting the needs of human consumption with a minimal environmental impact. Excellent results in terms of customer service quality Not only in technical quality but service quality objectives, that monitor the initiation, management and termination of contractual relationships and accessibility to this service, the Hera Group proved its ability to maintain excellent quality levels over time. In all areas served, ARERA recognised excellent contractual quality results, rewarding the performance in managing relationships with customers. This is a further sign of reliability and strengthens the link between operational efficiency and attention to served areas.
