COMISION NACIONAL DEL MERCADO DE VALORES (CNMV)

In compliance with article 228 of the Consolidated Text of the Spanish Securities Market Law, ABERTIS INFRAESTRUCTURAS, S.A. ("Abertis" or the "Company"), hereby notifies the Spanish National Securities Market Commission of the following

RELEVANT FACT Arteris, the subsidiary of Abertis which controls a network of 9 toll roads in Brazil, was declared the winner of the tender process of Rodovia dos Calçados (Itaporanga-Franca), a 720 kilometers highway in the state of Sao Paulo, for 1,213Mn BRL (~€353Mn) in real terms to be paid upon signing of the contract and a second payment of 225Mn BRL (~€65Mn) in real terms to be made upon handover of the current Autovias. The project includes an investment plan of around 5.0Bn BRL (~€1.5Bn).

Rodovia dos Calçados ("Lot C" of the State Concession Program) covers the 317 kilometers currently managed by Autovias (a concession in operation since 1998 and controlled by Arteris due to expire in December 2018) as well as 403 kilometers that were under direct administration of the state government.

The auction took place yesterday at BM&FBovespa S.A. - Bolsa de Valores, Mercadorias e Futuros ("BM&FBOVESPA") and was organized by Artesp, the state granting authority of Sao Paulo as part of the State Concession Program.

This is a 30-year concession expiring in 2047 located in one of the wealthiest and most dynamic Brazilian regions with a planned investment plan that includes the expansion of the current asset capacity with the duplication of 275 kilometers. Together with the concession fees to be paid, this investment plan will generate, according to the company's assumptions, a nominal equity IRR of 15%.

Starting in 2019, this new network is expected to generate 464Mn BRL (~€135Mn) in revenues and 290Mn BRL (~€85Mn) in EBITDA (most of it coming from the current well- known Autovias network).

All in all, this project expands the presence of Arteris in the Brazilian market and extends its average portfolio duration by 4 years. In addition, it allows Arteris to capture synergies and offers potential upsides on new investments.
