WEBUILD: LANE SECURES A USD 152 MILLION CONTRACT FOR THE I-77 ROADWAY SYSTEM TO SUPPORT NEW VOLKSWAGEN GROUP INDUSTRIAL PLANT IN SOUTH CAROLINA, USA

FROM THE START OF 2024, LANE HAS ACQUIRED AND IS FINALISING OVER €1 BILLION IN NEW CONTRACTS

Milan, 10 December 2024 – The effort to revamp the United States highway system continues with the contribution of the Webuild Group. The Group's U.S. subsidiary, Lane, has secured a USD 152 million (€137 million, 100% Lane) contract to enhance traffic flow on South Carolina's Interstate 77 (I-77). This project will support the development of Scout Motors' new manufacturing facility in Blythewood, a U.S. automotive company owned by Volkswagen.

The contract takes Lane's value for 2024, for newly acquired contracts and those being finalised, to over €1 billion. As of 30 June 2024, North America accounted for 13% of the Group's total revenue, reinforcing its role as a strategic market for infrastructure. This growth is reinforced by a modernisation plan to deliver safer, more efficient, and sustainable roads.

The new contract, commissioned by the South Carolina Department of Transportation (SCDOT), involves the design and construction of a highway system with an interchange providing access to the Scout Motors facility, which is expected to employ up to 4,000 people. This project will provide an economic boost to the region while reducing traffic congestion and improving mobility for Blythewood residents.

The core elements of the project include the construction of four bridges, access ramps, and a new eastwest connecting road that will link the I-77 to US Route 21. Part of US Route 21 will be diverted and relocated to allow for the crossing of the Norfolk Southern railway, which will serve the Scout Motors facility. The project

also includes the expansion of 4.8 kilometres (3 miles) of I-77 to three lanes, as well as the upgrading of existing interchanges.

Webuild, together with Lane, is currently working on several major road projects in the United States, including the recently awarded contracts to construct the twin Palisades tunnels, which will enhance New York's railway connections, as well as the upgrade of a section of I-64 in Virginia and the expansion of the Seminole Expressway/SR 417 in Florida. The company is also working on expanding I-275 in Tampa and strengthening the interchange between I-4 and Sand Lake Road in Orange County. Lane is also involved in the I-440 Beltline Widening project in Wake County, North Carolina, and the Mainline Turnpike project in Orlando, Florida. In addition, Lane is upgrading the 495 Express Lanes Northern Extension (495 NEXT) in the Washington, D.C. metropolitan area and carrying out the replacement and upgrade of the Wateree and Pond bridges on I-20 in Kershaw County, South Carolina.
