Narrative:

I was the sic and pilot flying a G200 that experienced a runway excursion upon landing. VMC weather ensued for the ILS approach and landing with light winds for a landing on runway 06. Aircraft was on stabilized approach at 1;000 ft AGL; slightly fast at 500 ft AGL; but immediately corrected and on speed for the remainder of approach and at touchdown. Touchdown occurred within the first third of the runway; on centerline; and on speed. Immediately after touchdown; aircraft swerved slightly left. I applied right rudder and deployed the thrust reversers at the same time to counteract the swerve and begin to slow the aircraft down. The aircraft swerved to the right and I advanced the power levers forward to re-stow the thrust reversers attempting to stop the swerve. The aircraft swerved to the left again; and I applied the brakes and right rudder to stop the swerve and the aircraft. The aircraft continued drifting to the left and departed the left side of the runway at approximately 35-40 KIAS and with 2;000 ft of runway remaining. We came to a stop just left of the runway in a muddy area. No injuries at all to either the crew or passengers. Upon departing the runway; the aircraft struck a runway edge light and a taxiway sign. This caused damage to the left flap and slat. Nose gear was damaged as well. PIC opened the cabin door and the passengers deplaned normally. Aircraft was towed to FBO.
