(Sharecast News) - Public Policy Holding Company said on Monday that it has filed an amended registration statement on Form S-1 with the US Securities and Exchange Commission, as it continued to progress plans for a potential initial public offering in the United States.

The AIM-traded strategic communications group said the amended filing was submitted in response to comments received from the SEC as part of its standard review process, and reflected ongoing engagement with the regulator.

It said the filing remained subject to further review and customary regulatory approvals.

Public Policy Holding Company previously applied to list its common stock on the Nasdaq Global Market under the ticker symbol 'PPHC'.

Following completion of the proposed US offering and listing, the company's shares were expected to be dual-listed on Nasdaq and on the AIM market of the London Stock Exchange, where they currently trade under the same symbol.

The company said it expected the shares to be fully fungible between the two markets, adding that it would provide further updates on the proposed listing as appropriate.

At 0900 GMT, shares in Public Policy Holding Company were up 0.24% at 1,052.5p.
