The hacker series starring Slater has got an early renewal midway through its second-season run.
The third installment is scheduled to air in 2017, reported Aceshowbiz.
"We couldn't be more proud of 'Mr Robot', a series that has pushed boundaries, captured the cultural zeitgeist, and been honored as one of the best dramas on television," said Chris McCumber, president of entertainment networks for NBCUniversal Cable Entertainment.
"Midway through its second season, Mr. Robot continues to break new ground and open up new opportunities for the network. We can't wait to see where Sam Esmail and the entire brilliant Robot team take us next."
It has already nabbed two Golden Globes and got six Emmy nominations including best drama series and a nod for Malek for his role as a hacker responsible for crippling the economy.
