We report soft point-contact spectroscopy studies of URu2Si2 both in the hidder order (HO) and the large-moment antiferromagnetic (LMAF) states accessed by pressure. In the HO state at ambient pressure, the spectroscopy shows two asymmetric peaks around the Fermi energy that emerge below the hidden order temperature T-HO. In the LMAF state at higher pressures, the spectra are remarkably similar to those in the HO state, indicating a similar Fermi-surface gapping in the HO and LMAF states and providing a clue to unraveling the puzzling HO state.
