Gregg, who is currently managing director of ASX-listed Primary Health Care (ASX: PRY), denies the accusations, the company said today in a statement.
The Primary Health Care board will meet today to "review the implications of this development for the primary group and its stakeholders".
The company is trading down 4.28 per cent at $4.03 per share late this morning.
Gregg has been served a Local Court attendance notice in relation to two contraventions of Section 1307(1) of the Corporations Act, related to allegedly falsifying company documents in 2011.
Gregg is due to appear in the Downing Centre Local Court in Sydney on 31 January 2017.
This matter is being prosecuted by the Commonwealth Director of Public Prosecutions.
