The transfer is reportedly worth an initial €10m plus €2m in variables. Torino had valued Berenguer, 25, at €15m but the clubs found a compromise.
Berenguer has agreed a four-year deal and is undergoing his medical ahead of putting pen to paper.
Athletic have a policy of only signing player with Basque blood and Pamplona-born Berenguer fits the bill.
Torino signed Berenguer from Osasuna in July 2017, paying €5.5m plus €1m in bonuses.
In total, Berenguer made 97 appearances for Torino, scoring 10 and assisting 12 goals.
