Completion of Share Consolidation & TVR

Public Policy Holding Company, Inc., a leading global strategic communications provider, is pleased to announce that following the previously announced approval of Shareholders on 29 September 2025, the Company's Reverse Stock Split ("Share Consolidation") has been effected in a ratio of one new share for every five existing shares (one-for-five) as held at the Record Date (1 October 2025).

For clarity, the Reverse Stock Split will not alter the underlying assets, business operations, management or financial position of the Company or the proportionate interests or rights of the Shareholders. For shareholders holding their shares in CREST, your custodian should update their records within the next one to five business days. Please contact your custodian if they have not updated their records by this point in time.

The Company confirms that the previous ISIN has been disabled in CREST as of market close on 1 October 2025 and that the new ISIN (US7444302084) has replaced it. The Reverse Stock Split has therefore been completed as of the Effective Date of 8:00 a.m. BST on 2 October 2025, with trading commencing under the new ISIN accordingly.

The Company's total issued and voting share capital upon admission will consist of 25,134,779 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.
