"We're very excited we were able to come to a good creative conclusion to the show", Sarandos told investors.
The production of series has been suspended since last October 31 after first allegations of sexual abuse by Spacey were known.
There will be no Kevin Spacey.
Star Trek actor Anthony Rapp accused Spacey of sexually assaulting when he was 14 years old and numerous allegations have since emerged against the actor.More news: Excited crowds gather to see Harry on first official outing with Meghan
Wright plays Claire Underwood, who started out as a less central figure on the show than her husband. "We have also decided we will not be moving forward with the release of the film Gore, which was in post-production, starring and produced by Kevin Spacey", the statement read. Season six was already set to be House of Cards' last before the allegations broke.
Sarandos spoke about "House of Cards" at USB's Global Media and Communications Conference in NY. The character has always been despicable, and now that Spacey's alleged actions have come to light, one imagines there's not a strong desire to give Frank Underwood an emotional farewell.
There are no hints as of yet about Frank Underwood's fate in the show or plot details for the eight episodes.
The actor is "taking the time necessary to seek evaluation and treatment", according to a representative. After initially filming the movie with Spacey as J. Paul Getty, director Ridley Scott re-shot those scenes with actor Christopher Plummer in the role instead.
