The cyclist's current contract with the Dutch bicycle racing team would expire in 2020, De Telegraaf said on Tuesday.
Roglič, who is one of the hottest cyclists in the market at the moment, will thus continue to race for the Jumbo-Visma team, participating in multi-stage races, including the three major ones - the first one, the Tour of Spain, will take place at the end of summer.
Ahead of the last stage, a 17-km time trial in Verona, the 29-year-old was fourth overall, but he showed his sprinting skills to overtake Spain's Mikel Landa to make it to the podium.
Competing for Jumbo Visma team from the Netherlands, Roglič finished the time trial in 22 minutes and 33 seconds to miss his third win in time trials at this year's Giro D'Italia by 26 seconds.
Competing for Jumbo-Visma, he claimed his second Tour de Romandie title only a week ago, and is viewed as one of the favourites for the three-week Giro d'Italia title.
This was Roglič's second stage win at the legendary race across Italy, which kicked off in Bologna. His first stage win at Giro d'Italia came in 2016.
With three stage wins, one second and one third stage spots, the 29-year-old member of the Jumbo-Visma team also won the green jersey in the points classification.
Overall, he finished the race 49 seconds ahead of Portuguese rider Rui Costa, and 1:12 minutes ahead of last year's Tour de France winner, Geraint Thomas of Wales.
