MILAN, November 12, 2026 - The Board of Directors of Webuild (Euronext Milan: WBD) examined the following data and information relating to the business performance since the start of 2026.

****

Pietro Salini, Chief Executive Officer: “In a world that keeps asking for more infrastructure, Webuild continues to grow. Since the beginning of the year, we have acquired more than €11 billion in new orders, while tenders awaiting outcome have risen to almost €25 billion - proof of strong demand precisely in the markets where we are a leader. We are securing highly complex projects, such as a second section of the Ontario Line in Toronto, the Genoa Undersea Road Tunnel and Christchurch Men’s Prison in New Zealand. In Zambia, we are the preferred bidder for the Lobito Railway Corridor, a strategic project under Italy’s Mattei Plan. We have delivered projects that change people’s lives, from the first section of the Naples–Bari high-speed railway to the line bringing Turkey’s high-speed rail network to the doorstep of the European Union, as well as major water infrastructure projects in Seattle and Kansas City. Behind these successes are more than 83,000 people, including 22,000 in Italy, where we have hired approximately 2,000 since the beginning of the year. Together with our supply chain, we are investing in innovation and artificial intelligence to build in increasingly efficient ways. This growth rests on solid foundations: S&P has confirmed the Group’s rating, international rankings place us first in the world in the water sector, and we confirm our 2026 targets. We look to the future with confidence. Through the offer for Trevi, now mandatory and unconditional, we will bring expertise in special foundations and underground engineering into the Group, strengthening the companies that work with us along the supply chain and providing our clients with an even more competitive integrated solution.”

NEW ORDERS

Total new orders acquired since the beginning of the year, including variation orders, amount to €11.1 billion. This includes €3.0 billion of tenders in which Webuild is the best bidder.

The project, with a total value of €2.7 billion (CAD 4.32 billion) and commissioned by Metrolinx and Infrastructure Ontario, was awarded to a joint-venture led by Webuild, with a 50% share, together with FCC.

COMMERCIAL PIPELINE 

The Group’s short-term commercial pipeline amounts to €99.3 billion, including tenders submitted and awaiting an outcome for €24.9 billion and tenders to be presented for €14.9 billion.

The Group continues to closely monitor opportunities in strategic markets such as Europe, Oceania, North America and Saudi Arabia, where it holds a strong competitive position.

The global environment offers significant growth opportunities for the infrastructure sector. In Europe, water infrastructure renewal programmes, railway network modernisation and NATO policies are driving sustained demand for strategic investment. In Italy, the market is supported by growing investment in hospital facilities, defence programmes, urbanisation and the completion of transport investments launched in previous years. In North America, demand is supported by extensive public investment and public-private partnerships aimed at renewing transport networks and modernising water infrastructure. Oceania offers significant opportunities related to the development of energy and mining resources, urban renewal, including hospitals and stadiums, and the transport, ports and airports segments. In Saudi Arabia, the development of an integrated urban system featuring state-of-the-art roads, railways and metro systems is accompanied by investments in connectivity infrastructure, including airports, and social infrastructure such as stadiums.

In addition to its core markets, Webuild selectively pursues opportunities in other geographies where it can leverage its local experience and technical expertise to achieve an appropriate balance between risk and return, with a particular focus on major strategic transport corridors and hydroelectric plants supported by international cooperation programmes.

Below is the breakdown of the short-term commercial pipeline by category and geographic area:

BUSINESS OUTLOOK

In light of the commercial and operating performance and the size and quality of the order backlog, 2026 guidance is confirmed: revenue exceeding €13.6 billion, EBITDA exceeding €1.2 billion, with margins continuing to expand, and a solid net cash position exceeding €300 million at year-end.

The guidance already fully reflects the effects of the termination of the NEOM projects in Saudi Arabia, which have been fully absorbed by the size and diversification of the backlog. The guidance also assumes no substantial change in the geopolitical scenario, no extreme movements in raw material prices, and no significant supply chain disruptions.

Guidance is prepared on a standalone basis and excludes all effects from the tender offer for Trevi, including shares already purchased. From October to date, Webuild has purchased 25.8 million Trevi shares, increasing its stake to 44.41% of the share capital.
