Question on whether "entire function, nowhere zero, has entire logarithm" holds for matrix-valued entire functions as well

It is known that an entire function that is nowhere zero must be the exponential of another entire function.

Does this hold for matrix-valued functions as well? That is, given a matrix-valued entire function, none of whose eigenvalues is zero anywhere(save complex infinity, trivially), is it true that it must be the exponential of another matrix-valued entire function?
