The Clonbullogue racer will continue with Rodin Motorsport next year.
Alex Dunne will be racing in Formula Two once again for 2026.
Dunne landed two race wins and 8 podiums over the course of his rookie campaign to finish fifth in the championship standings.
The news comes after the final round of the season in Abu Dhabi where the Offaly teenager scored a single point in Saturday's sprint race.
His feature race came to a premature end after he collided with Victor Martins early on.
Dunne will carry a 10 second penalty into the new season following the crash.
