The State challenges the departure sentence after Appellee was convicted of aggravated assault with a firearm. Appellee commendably concedes error on this point but asserts by cross-appeal that the court gave erroneous jury instructions that amounted to fundamental error, necessitating a new trial. We agree with Appel-lee and reverse and remand for a new trial.
The aggravated assault instruction was fundamentally erroneous because it was based on a theory not charged in the information. Grau v. State, 101 So.3d 922 (Fla. 5th DCA 2012); Fuentes v. State, 730 So.2d 366 (Fla. 4th DCA 1999). Because of our conclusion on this issue, it is not necessary to address the State’s argument *680that Appellee invited error in the self-defense instruction.
REVERSED AND REMANDED.
