Public Policy Holding Company, Inc.

("PPHC", the "Company" or the "Group")

Board Appointment & Removal of Reg-S restrictions

Public Policy Holding Company, Inc., the leading government relations and public affairs group of companies providing a comprehensive range of advisory services, is pleased to announce that, further to its announcement of 3 July 2023, Roel Smits (Chief Financial Officer), will join the Group's Board of Directors with immediate effect.

Removal of Reg-S restrictions from shares of common stock

To facilitate compliance with United States securities laws, depositary receipts representing shares of PPHC Common Stock listed on AIM under the symbol "PPHC" have been subject to a prohibition on transfers to United States persons who are not qualified institutional buyers (the "AIM Transfer Restrictions"). The Board has approved the removal of the AIM Transfer Restrictions, subject to the Board's power to reinstate such restrictions at any time at its discretion. The Board expects this to enhance the liquidity in the trading of PPHC's common shares and allow investors who may previously have had difficulty in dealing to deal more easily.

PPHC anticipates that the removal of the AIM Transfer Restrictions will become effective in the coming weeks and further announcements will be made as appropriate.

Simon Lee, Chairman of PPHC, commented:

"I am pleased to announce the formal appointment of Roel Smits to PPHC's Board. The Group's seven-person Board provides PPHC with deep expertise and is very well placed to drive PPHC's ongoing growth in the years ahead.

"Although trading in PPHC's shares has been possible on a few trading platforms since IPO, we have received requests from potential shareholders to ensure that trading is possible on certain global trading platforms. We believe that the lifting of the Reg-S restrictions will enable this to occur and will therefore support trading liquidity."
