Exceptional field theory provides a very powerful tool to obtain explicit consistent truncations of eleven-dimensional and type II supergravity down to gauged supergravity in lower dimensions. In this talk I will introduce the E9 exceptional field theory that we have recently constructed with Ciceri, Inverso, Kleinschmidt and Samtleben and will describe its generalized Scherk-Schwarz reductions to two dimensions. This permitted us in particular to prove that SO(9) gauged supergravity is a consistent truncation of eleven-dimensional supergravity with the supersymmetric Nicolai–Samtleben vacuum that can be interpreted as the near horizon geometry of a stack of D0 branes and should allow to shed light on the conjectured correspondence between the de Wit–Hoppe–Nicolai M-theory matrix model and M-theory on AdS2 × S8 × S1
