Weather
While departing on a SID we were advised on the ground to level at 5;000 feet MSL. At approximately 4;500 feet; our aural warning on our autopilot went off and a violent pitch up moment occurred with I believe was due to turbulence or possible wake turbulence. I was able to get aircraft back under control at approximately 5;500 - 5;700 feet MSL before I could advise ATC. They informed me I should be level at 5;000 feet and cleared to 6;000 feet. I realize this is a pilot deviation of 700 feet; but [I was] unable to control the aircraft climb for 600 feet - 700 feet due to pitching moment. I informed Center of the severe turbulence in the area and heard other pilots on frequency reporting turbulence. Crew was not tired and properly rested. This event caught us by surprise.
[Report narrative contained no additional information.]
EMB-550 flight crew reported severe turbulence during initial climb resulting in a momentary loss of aircraft control while attempting to level off.
