RNS Number : 6734X  Public Policy Holding Company, Inc.  23 March 2026

Public Policy Holding Company, Inc.

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

Appointment of Chief Administrative Officer

Public Policy Holding Company, Inc., (Nasdaq: PPHC) (AIM: PPHC), a leading
global strategic communications provider offering a comprehensive range of
advisory services in the areas of government relations, public affairs, and
corporate communications, announces the appointment of Matthew Mazzanti as
Chief Administrative Officer ("CAO"), effective 20 March 2026.

Matthew is promoted from his current position, where he has led the Group's
corporate communications and investor relations functions and supported
corporate development activities. He has played a central role in a broad
range of PPHC initiatives, including providing support to the senior
leadership team and member firm leadership.

As CAO, Matthew will continue to report directly to Stewart Hall, Chief
Executive Officer. He will maintain his existing responsibilities while taking
on broader responsibility for supporting the execution of the Company's
strategic priorities, strengthening coordination throughout the holding
company, and driving operational efficiency across the platform.

Matthew joined Crossroads Strategies, one of the Group's founding member
firms, seven years ago before progressing to a cross-functional position with
PPHC. He was involved in the Company's AIM IPO in 2021 and played a key role
in the recent listing on the Nasdaq Global Market.

The position of Chief Administrative Officer has been vacant since the
retirement of Bill Chess in July 2024.

Stewart Hall, CEO of PPHC, commented:

"As PPHC continues to expand globally and enhance its suite of services and
portfolio companies, the CAO position is increasingly important for the
Company. Matthew has played critical roles going back to our AIM listing over
four years ago in investor relations, intercompany relations, talent
management, M&A, and business development. His knowledge of each of our
member companies, their services and people is unmatched, and I am pleased to
elevate him to the position with the Board's approval. Filling the CAO
position will allow us to continue to drive intercompany synergies and support
our number one asset - our talented and skilled practitioners across the
globe."
