Restricted Shares Issuance and PDMR Dealing

Public Policy Holding Company, Inc., the leading government relations and public affairs group of companies providing a comprehensive range of advisory services, announces that it has granted restricted stock shares in the Company, which will rank pari passu with the Ordinary Shares ("RSs"), to certain senior employees ("PDMRs") of the Company, under PPHC's 2021 Omnibus Incentive Plan ("Omnibus Plan") that was adopted in connection with the Group's admission to AIM in December 2021:

RSs

In total 1,629,041 RSs have been granted on 31 October 2023 under the Omnibus Plan. Of this tranche, 724,018 RSs have been granted to PDMRs. The RSs will vest across a five-year period from the grant date, split equally each year. All RSs will be subject to certain acceleration and clawback events tied to continuation of employment and compliance with various employment-related agreements.

Application will be made for the new RSs, which will rank pari passu with the existing Common Shares in issue, to be admitted to trading on AIM. Dealings are expected to commence on or around 7 November 2023.

Following this issue of shares, the Company's total issued and voting share capital upon admission will consist of 115,094,514 Common Shares. This figure may be used by shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, securities of the Company.

As set out in the Group's Admission Document, PPHC strives to attract and retain high quality staff in order to best serve its clients. These Omnibus Plan awards are being made in order to incentivise senior management and a broad range of employees through equity-based awards, further aligning the interests of employee shareholders with PPHC's core mission and objectives.

The resultant holdings of RSs by PDMRs are set out below:
