Beyaz signed for VfB in July 2021 from Fenerbahce and spent last season on loan at 1. FC Magdeburg.
The 19-year-old has made four Bundesliga appearances and one in the DFB Cup for VfB to date. For Magdeburg the Turkish U21 international featured three times in Bundesliga 2 and once in the cup.
VfB sporting director Fabian Wohlgemuth: “This is a thoroughly sensible move for Ömer. With Hatayspor in the Süper Lig he has the prospect of regular game time, which is particularly important at his age. We wish him and his new club a successful season.“
