The drama, which stars Jason Bateman, Laura Linney and Julia Garner, has been renewed for 14 final episodes with the season split into two seven-episode parts.
The new season will mark the final chapter in the Byrde family's journey from suburban Chicago life to their criminal enterprise in the Ozarks, particularly after that season three ending.
Bateman plays Marty Byrde, a financial advisor-turned-money launderer for a Mexican drug cartel, who moves to the Lake of the Ozarks to make good for the cartel. Linney stars as his wife Wendy, who becomes wrapped up in a series of schemes, including casino operations in season three. Cast returning includes Garner, who plays Ruth Langmore, the Byrde's younger consigliere, Sofia Hublitz as Charlotte Byrde, Skylar Gaertner as Jonah Bryde, Charlie Tahan as Ruth's cousin Wyatt Langmore and Lisa Emery as local heroin distributor Darlene Snell.
Mundy added, `We're so happy Netflix recognized the importance of giving Ozark more time to end the Byrdes' saga right. It's been such a great adventure for all of us - both on screen and off - so we're thrilled to get the chance to bring it home in the most fulfilling way possible.
Cindy Holland, VP of Original Content, said, `Ozark is a gripping drama that has captivated audiences all around the world and garnered tremendous critical acclaim. We're so grateful to Chris, Jason, Laura, Julia and the entire cast and crew for all their tireless dedication to the show and can't wait to see how the Byrdes' journey comes to a close.`
