All four host stars have been independently observed by the EXoPlanets aRound Evolved StarS (EXPRESS) program and the Pan-Pacific Planet Search (PPPS). The companion signals were revealed by multi-epoch precision radial velocities obtained during nearly a decade. The planetary companions exhibit orbital periods between $\\sim$ 1.2 and 7.1 years, minimum masses of m$_{\\rm p}$sini $\\sim$ 1.8-3.7 M$_{jup}$ and eccentricities between 0.08 and 0.42.
