BUILDING ON
SUSTAINABLE
VISIONS
For 80 years, a milestone we are celebrating this 2025, we have been offering the Italian and global markets an innovative building concept based on Modern Methods of Construction. Since the first generation, we have been pursuing this innovative approach to doing business with conviction: the construction world is undergoing a revolution, and every revolution starts with a cultural revolution first of all. Our mission is to contribute to this cultural revolution, which we do through activities that promote the application of off-site technologies on a daily basis. 2024 was a year that confirmed our values and shared vision. We embarked on paths that were completed fully in 2025, such as the joint venture with Marcegaglia Steel: a collaboration that marks a turning point in Manni Group’s internationalisation strategy, and strengthens our placement on a global scale. This synergy takes on an even more significant value because it combines with Isopan’s 50th anniversary, an anniversary that celebrates half a century of expertise, industrial evolution and ability to stay ahead of the challenges the sector poses. Looking to the future, we continue to invest in sustainable solutions, and actively contribute to decarbonising construction and consolidating our commitment to a future built on innovation, responsibility and positive impact.
2024 and early 2025 were periods of profound political change, with significant social and economic impact that was radical compared to past experiences. 2025 is also the year in which our Group, which has always focused on a long-term vision and business sustainability, celebrates its 80th anniversary. The effort to build long-lasting organisations has taken great skill in the various processes, and has forced us to react with flexibility, adaptation and innovation in the face of systemic crises. This is only possible by expressing a vision to steer the business into the future, one in which we can shape the chaos that surrounds us as much as possible. We believe that investments in R&D and in creating highly qualified partnerships now form the basis of our national and international development trajectories. We therefore maintain the process of internationalisation and technological innovation, with the necessary geographical adaptations and appropriate attention to supply chain adequacy by collaborating with leading global companies, research centres and universities. Giving the market products, systems and services that contribute to improving ESG impacts remains a central goal. In a trend of political hype that would seem to slow down or mute sustainability topics, we believe instead that these are a current that has become a widespread requirement, which is demanded and greatly needed. When looking ahead, we look further with the contribution of younger generations, who are crucial to the technological and sustainable development of (their) future.

Manni Group aims to contribute to reducing the carbon footprint in the construction sector.
For this reason, it actively promotes the culture of off-site construction: this is one of the Modern Methods of Construction and involves reorganising processes to benefit greater efficiency and quality. The building components are designed and manufactured within the production plant and then transported to the construction site, where they are dry-assembled, drastically reducing on-site processing.
We work to develop increasingly innovative solutions, relying on the strength of being able to integrate different systems by drawing on the valuable cross-disciplinary technical expertise of the companies within the entire Group. This means we are able to support our customers during analysis and development of complete projects.
Sustainability in the form of ESGs represents a way of doing business that enables growth that is in harmony with the environmental and social contexts in which it operates. Consistency means we are able to contribute to the fight against climate change and the transition to a circular economy.
Innovating and investing in R&D to respond to new market needs and improve production processes to increase their efficiency and effectiveness while reducing their environmental impact.
Manni Group is an open, dynamic and adaptive organisation that places increasing importance on alliances with key partners to drive innovation, expansion of markets, regions and industrial investments.
It allows us to diversify our business geographically, spreading risk and investment across European and non-European markets. The ability to deal with different cultural backgrounds also allows us to grow and develop skills within a global environment.
Manni Group considers respecting ESG factors to be a prerequisite for responsible growth: it is aware of the need to integrate environmental and social aspects into transparent governance, and believes that an organisation’s overall performance is closely related to the wellbeing of the social context in which it operates and the impact it has on the surrounding environment.
ESG: Environment
A distinguishing feature of the Group’s activities is the circularity of the products used: Manni Group purchases materials that meet precise standards in terms of percentage recycled content, and all steel and rockwool waste is recovered to create new raw material. The products are suitable for international sustainable construction certifications, which state that the origin of the material used must be tracked and disclosed, something which is also required in public procurement under the European Union’s Green Public Procurement plan.
*Recycled content is the percentage by weight of secondary raw material used in the production of a product. The recycled content is estimated on the basis of ISO 14021 compliant declarations and EPD certificates from only those suppliers who have provided this information.
ESG: Environment
In 2016, Manni Group initiated an ambitious plan to reduce our greenhouse gas (GHG) emissions. Scope 1, Scope 2 and Scope 3 emissions are monitored and reported internally within a GHG emission inventory in accordance with EN ISO 14064-1:2019, which is certified by a third party.
About 99% of the Group’s total emissions are Scope 3, associated with companies active in the industrial sector. For this reason, Manni Group, in agreement with suppliers, has planned a series of actions related to logistics and production of procured goods.
Direct emissions: 3,504 tCO2eq
Indirect emissions from energy consumption: 5,404 tCO2eq
Other indirect emissions from upstream and downstream activities of the organisation: 1,004,147 tCO2eq
ESG: Environment
The construction sector, in which Manni Group operates, is responsible for about a third of global greenhouse gas emissions. The Group includes several companies operating in the manufacture of metal structures and parts of structures (ATECO Code 25.11.00), wholesale of metal ores, ferrous and non-ferrous metals in primary forms (ATECO Code 46.72.10), manufacture of open sections and ribbed sheets (ATECO Code 24.33.01), and installation of electrical systems in buildings or other construction works (including maintenance and repair) (ATECO 43.21.01).
In 2024, the Group consumed 3,2761.32 MWh of energy, of which 50.44% was from renewable sources
In 2024, the Group produced 5,729.44 MWh of energy from renewable sources
ESG: Social
As stated in the Sustainability Policy, the Group embraces and considers the Universal Declaration of Human Rights. To reinforce our commitment, in 2024 we joined the United Nations Global Compact, an initiative to encourage companies to share, support and enforce a set of core principles relating to human rights, labour standards, environmental protection and anti-corruption. The ten principles of the UN Global Compact are shared universally as they derive from the Universal Declaration of Human Rights, the ILO Declaration, the Rio Declaration and the UN Convention Against Corruption.
The goal of UN Global Compact is to accelerate and expand the collective global impact of companies by supporting the Ten Principles and achieving the Sustainable Development Goals (SDGs) through responsible companies and ecosystems that foster change.

The Giuseppe Manni Foundation was founded in 2010 by entrepreneur Giuseppe Manni, together with a group of doctors, researchers and philanthropists led by Prof. Massimo Gerosa, with the aim of promoting progress in neuroscience. Since its inception, the foundation has been committed to supporting biomedical research on the nervous system, with a special focus on developing neurology and neurosurgery in the Verona area.
Its work is based on active collaboration between the academic world, public health and the social fabric and exploits the joint participation of institutions and citizens. The foundation supports the most advanced scientific and technological research in close synergy with the University of Verona and the Azienda Ospedaliera Universitaria Integrata (integrated hospital trust – AOUI), both international centres of excellence. It is committed to promoting increasingly innovative, accessible and person-centred healthcare, making scientific knowledge a tool for equity, care and social development.
In 2025, Manni Group is proud to celebrate this important milestone together with the Giuseppe Manni Foundation: 15 years of shared commitment to progress in neuroscience, alongside the University of Verona and the Azienda Ospedaliera Universitaria Integrata Verona.
A path that continues to create value by supporting advanced research and rewarding the talents of two female researchers who have been awarded grants for projects on refractory depression and early diagnosis of dementia.

ESG: Governance
Manni Group SpA is the holding company that exercises management and coordination functions over its subsidiaries, defining their strategies and administering their shareholdings including through service contracts.
The Group’s Corporate Governance document aims to convey to those who work with the company a clear vision of a correct and responsible entrepreneurial activity, with the intention of laying down some rules on the fundamental aspects that qualify governance. As the need to delegate to the outside world and to cope with potential risks increases, this serves to balance autonomy and control correctly.
The business is run through a system of delegated powers combined with audit tools, which still leave ample room for operational independence of the subsidiaries and professional autonomy of the employees. Furthermore, through the structure of delegation and control, the Board of Directors (BoD) guarantees its stakeholders that the business is run correctly, responsibly and transparently.

In 2016, the Sustainability role was established when the Business Sustainability Officer (BSO) was appointed with the task of guiding the Group towards an increasingly sustainable business model by implementing and managing corporate strategies and initiatives aimed at promoting ESG issues. The BSO is also responsible for drafting the Business Sustainability Plan (BSP) and monitoring its implementation.
From 2023, the Sustainability department managers were certified as Sustainability Managers and Sustainability Practitioners by CEPAS, and qualified by the ALTIS – Università Cattolica del Sacro Cuore executive course on “Professione Sostenibilità” (Sustainability Profession). The CEPAS (Institute for the Certification of Skills and Training) certifications issued by Bureau Veritas comply with the UNI/PdR 109.1 standard, which defines the requirements for professionals operating in the field of sustainability.

ESG: Governance
The Manni Group’s governance includes Enterprise Risk Management (ERM), a risk management system that includes the holding’s governance and covers the governance of all the companies, implementing all aspects of integrated risk management to safeguard assets and business continuity.
The management focusses on markets, customers and products, as well as on risks strictly related to the business. This ensures that a fair balance is achieved that protects the company from potential losses and damage, while leaving room for the entrepreneurship of the management, with full knowledge of the delegated powers.
The ERM structure allows the governance to constantly monitor the corporate risk situation, identifying current and potential positive and negative impacts that the organisation could cause (or may have caused), broken down by area of responsibility, and to intervene where necessary with improvement plans to implement specific preventive or corrective actions.
ESG: Governance
We believe that ensuring the integrity and sustainability of the supply chain requires the commitment of all stakeholders. Manni Group also strengthens ESG reporting by constantly monitoring the environmental, social and governance impact of the entire supply chain.
The holding company’s Procurement department gives a uniform process for collaborating with stakeholders, as well as seizing the opportunities arising from centralised management of large volumes.
Most core products and services are purchased from suppliers in the European Union, countries where health and safety practices and violations of human and labour rights are protected by local regulations. Particularly energy-intensive suppliers are committing to major decarbonisation plans. The sourcing process for chemical products increasingly involves searching for suppliers who adhere to the ESG parameters adopted by the Group, as outlined in the Sourcing Policy.
