Italian company ITINERA with more than 100 kilometers of tunnel construction experience is awarded the construction of the Torino - Lyon tunnel on the Italian side. ITINERA will build 30 kilometers long tunnel. 18 Kilometers will be via Tunnel Boring Machine method and the 12km NATM. ITINERA press release gives the detailed information.

ITINERA AWARDED THE CONTRACT FOR THE EXCAVATION AND CONSTRUCTION OF THE BASE TUNNEL ON THE ITALIAN SIDE OF THE TURIN-LYON RAILWAY LINE

▪ The project involves the excavation and construction of the Mont Cenis base tunnel on the
Italian side starting from the Chiomonte construction site
▪ Project value about 1.1 billion euros
▪ Itinera leads a joint venture together with Ghella and Spie Batignolles

Tortona, August 31st 2023. Itinera, the ASTM Group major works company, has been awarded the
international tender for the excavation and construction on the Italian side of the base tunnel of the Turin-
Lyon high-speed/capacity railway line.

The announcement was made by the top management of the Public Promoter "Tunnel Euralpin Lyon Turin"
(TELT) at a public meeting.

Itinera will carry out the project as leader with a 41% share in a joint venture together with Ghella (39%
share) and Spie Batignolles (20% share).

This award, worth about 1.1 billion euros, is the latest related to the major civil works of the international
section of the new freight and passenger rail line between Italy and France, with a total length of 65 km
between the international stations of Saint Jean de Maurienne (France) and Susa (Italy), where it will be
connected to the existing line. The main work is the Moncenisio base tunnel, the longest double-bore with
single track railway tunnel ever built, 57.5 km long.

Specifically, the contract awarded to the Itinera-led JV is for the construction of the Turin-Lyon base tunnel
in Italy, from Susa to the French border (operating sites CO03 and CO04), and includes the construction of
about 10 km of the base tunnel, divided into two bores, as well as the down-ramps and the by-passes, leading to a total length of the tunnels to be built of about 30 km, of which 18 km in mechanized excavation (TBM) and 12 km in traditional excavation.

Total excavation is about 6 million tons of material, while total concrete production (cast-in-place, jet-
grouting and for precast segments) is about 730,000 cubic meters.

During the execution of the 91-month contract, a peak employment of workers of about 700 man/days is
expected.

Following the beginning of work on the French side in 2021, the awarding of the contract on the Italian side
as well represents a crucial step in this strategic infrastructure, which is one of the main components of the
Mediterranean Corridor, one of the 9 axes of the Trans-European Transport Network (TEN-T). This axis will
connect southwestern Europe with central and eastern European countries.

The Turin-Lyon railway line also has significant sustainable and environmental value: when fully operated
starting on 2032, it is expected to remove more than 1 million trucks from Alpine roads, thus saving 3 million tons of CO2 each year.

Itinera is also currently involved in the excavation of the French-side Lot 3 of the tunnel, between the France-side entrance portal at Saint Julienne Mont Denis and Saint Martin La Porte, as well as in major international transportation projects, including the new "Storstrøm Bridge" in Denmark, a 3.8-kilometer-long rail and road bridge that will be the new connection axis between Copenhagen (Denmark) and Hamburg (Germany).
