OUTLOOK

OUTLOOK FOR 2018 NORTH AMERICA Average rig count expected to moderately increase in 2018, assuming no significant change in WTI OCTG consumption per rig should continue to rise Benefit from this favorable market conditions and FY impact of volume and price achieved in H2 2017 EAMEA O&G: Increasing tender activity should result in higher bookings with impact on deliveries to materialize mostly as from 2019 Industry: favorable trend in demand should be confirmed Power Generation: declining conventional power plant projects BRAZIL O&G: Petrobras drilling activity expected to remain stable. We target to renew our frame agreement in the course of H1 2018 Industry: better momentum should be confirmed Group results dependent on consumable prices and forex, which recently demonstrated unusually high volatility and unfavorable evolution Transformation Plan will continue to generate significant gross savings and to reinforce Vallourec s competitiveness 17
