The move does not come as a shocker since the summer drama had never been a strong ratings performer for the network since it debuted in July 2014, reported Ace Showbiz.
"CBS, Halle Berry and the producers have decided to conclude the 'Extant' story after last season's exciting and fitting conclusion," CBS Entertainment president Glenn Geller announced the cancellation.
Berry, 49, said, "I am so proud of what we accomplished on 'Extant'. This season seemed such a natural place to end Molly's journey that I, along with CBS, felt it best served the story to leave it there.
CBS will continue its partnership with Berry as the Oscar-winning actress is set to executive produce a new legal drama for the network.
