  The extremely large magnetoresistance (XMR) effect in nonmagnetic semimetals
have attracted intensive attention recently. Here we propose an XMR candidate
material SrPd based on first-principles electronic structure calculations in
combination with a semi-classical model. The calculated carrier densities in
SrPd indicate that there is a good electron-hole compensation, while the
calculated intrinsic carrier mobilities are as high as 10$^5$
cm$^2$V$^{-1}$s$^{-1}$. There are only two doubly degenerate bands crossing the
Fermi level for SrPd, thus a semi-classical two-band model is available for
describing its transport properties. Accordingly, the magnetoresistance of SrPd
under a magnetic field of $4$ Tesla is predicted to reach ${10^5} \%$ at low
temperature. Furthermore, the calculated topological invariant indicates that
SrPd is topologically trivial. Our theoretical studies suggest that SrPd can
serve as an ideal platform to examine the charge compensation mechanism of the
XMR effect.
