INDIRECTLY, IN ANY COUNTRY WHERE SUCH DISCLOSURE, P UBLICATION, OR DISTRIBUTION WOULD CONSTITUTE
A VIOLATION OF APPLICABLE LAWS OR REGULATIONS IN TH AT JURISDICTION
2 • An Offer entirely in cash of 4.50 Euro per share, r epresenting a premium of approximately 30% over the official price as of the reference date 1, leaving tendering shareholders with no exposure t o future financial market volatility.
• An Offer fully financed by a dedicated facility, co vering both the acquisition of all Trevi shares and the potential refinancing of Trevi's indebtedness, whic h is not a condition of the Offer.
• The integration of Trevi's expertise in special fou ndations into a global industrial group — which reported revenues of Euro 13.6 billion in 2025 and an order backlog of Euro 54 billion as at 30 June 2 026 — that will enable Trevi to continue and expand its business, while gaining direct access to the netwo rk of the Webuild Group, which operates in some 50 cou ntries and draws on over 120 years of history.
• Joining the Webuild Group would open new growth opp ortunities for Trevi, its people and its know-
how, while preserving its identity, its operational headquarters in Italy and its technical, design an d managerial expertise. Trevi would continue to opera te on an open-market basis, offering its high value -
added services to the entire sector.
• An industrial rationale rooted in the value chain: the success of the Offer would enable the Webuild Group to bring in-house high value-added expertise currently also entrusted to third parties, and to strengthen its competitive positioning in tenders f or large and complex projects by offering a more efficient and competitive integrated end-to-end sol ution, also in terms of pricing.
• A deepening of an industrial partnership already es tablished over many years: Webuild and Trevi work side by side on some of the largest construction si tes in Italy and abroad, from the Rogun Dam in Tajikistan to Line C of the Rome Metro - a relation ship that the transaction would allow them to consolidate in the long term.
• Italian excellence on a global stage: becoming part of one of the world's leading players in major infrastructure, by order backlog, global positionin g and financial strength, would broaden Trevi's commercial reach, giving it access to new geographi es, new clients and larger and more complex tenders for projects.
