In the present investigation, the author introduces two interesting subclasses of normalized meromorphic univalent functions $w=f(z)$ defined on $\tilde{\Delta}:= \{z \in \mathbb{C}: 1<|z|<\infty\}$ whose inverse $f^{-1}(w)$ is also univalent meromorphic in $\tilde{\Delta}$. Estimates for the initial coefficients are obtained for the functions in these new subclasses.
Keywords: meromorphic functions, univalent functions, bi-univalent functions, inverse functions, coefficient bounds
