The signing of the New Agreement testifies to the commitment of the main Webuild shareholders, even through specific lock-up commitments, ensuring continuity of the governance, management and shareholder structure of the Company along a temporal horizon during which Webuild, among other things, will be protagonist in constructing important infrastructural works included within the National Resilience Plan (PNRR - Piano Nazionale di Ripresa e Resilienza).

The Company adhered to the New Agreement - according to which the Essential Information will be made available, pursuant to the Law, on the company website (www.webuildgroup.com) in the "Governance/Other documents" - section, with the sole intention of expressing its consensus to the premature rescission of the Original Investment Agreement that it signed in the aforementioned Progetto Italia.
