Transaction Overview

WPI Strategy, which was founded in 2014 by Nick Faith and Sean Worth, specialises in research-driven advocacy. Its offer combines communications and policy advisory with an industry-leading in-house economics capability, led by Martin Beck, the former Chief Economic Adviser to the EY ITEM Club. The firm regularly produces high-quality research and due diligence to support the commercial and reputational goals of its clients, including Abbvie, Bupa, Cisco, London City Airport, Microsoft, Pension Insurance Corporation, and VodafoneThree.

In the twelve months to January 2026, WPI Strategy generated approximately £2.45 million of net revenue and employs approximately 14 professionals. Also in 2025, WPI Strategy was awarded 'Consultancy of the Year' by City AM. The team was also recognised by PR Week for its support in the merger of Vodafone and Three, and has added new talent already in 2026.

All employees and advisers of WPI Strategy will transition as part of the Acquisition. The business intends to retain its trading brand and operate as the economics and policy consulting unit within Pagefield Group, and Nick Faith and Sean Worth will join Pagefield's Senior Leadership Team.

Strategic Rationale

The Acquisition advances PPHC's long-standing objective of building a portfolio of complementary strategic communications businesses that enhance the Group's ability to deliver integrated policy, communications and reputation advisory services.

WPI Strategy brings a differentiated research-driven advocacy model combining policy advisory, economic modelling, impact analysis, and communications strategy grounded in quantitative evidence.

The transaction further strengthens PPHC's presence in the UK, one of the world's most important policy and financial centres, following the Group's acquisition of Pagefield in 2024. The combined platform will comprise over 60 client-facing professionals.

Consistent with PPHC's acquisition strategy, the transaction is expected to be immediately earnings accretive and aligns with the Group's target margin profile. The addition enhances both organic growth prospects and long-term shareholder value.

Stewart Hall, CEO of PPHC, commented:

"This acquisition exemplifies our disciplined approach to growth. We are adding a meaningful, differentiated capability that strengthens our ability to combine economic evidence, policy advocacy and strategic communications to benefit our clients. Following our Nasdaq listing, our intention remains to deploy capital in a focused and accretive manner. This transaction is a perfect example of that strategy in action."

Nick Faith, Co-founder of WPI Strategy, commented:

"We are delighted to be joining the PPHC family and broadening the network's presence in the UK and Europe. The combination of WPI Strategy's economic and political consulting expertise with Pagefield's fully-integrated public affairs, digital and corporate communications capabilities means that, together, we can offer clients the most comprehensive and fully integrated offer in the UK market.

"We have also been developing our international capabilities via marquee global accounts and look forward to working closely with PPHC and its existing member companies to bring our consulting offer to the United States and other growth markets."

Oliver Foster, CEO of Pagefield Group, commented:

"WPI Strategy has for many years been delivering some of the best economic and policy analysis in the London market, and they have a particularly strong track record working for some of the world's most interesting organisations on some of the most important policy challenges of our time - both domestically and internationally. The synergies - for our clients and our teams alike - are clear. I'm thrilled that they're now a core part of the Pagefield and wider PPHC team."
