We are delighted to announce that Principeo has recently completed the acquisition of Warner McCall via a 100% share purchase, significantly deepening and expanding the capabilities we offer to UK Defence.
Principeo uniquely offers Defence leaders and their teams the specialist, strategic support to cut cognitive load and accelerate delivery of big picture value. With our heritage in cross-industry strategic change and deep Defence-sector expertise across digital, technology, industry strategy and lean governance, we help leaders navigate systemic challenges to unlock delivery at pace.
Warner McCall has a rich heritage in supporting senior Defence leaders with some of their most complex challenges, and this perfectly complements our unique value proposition at this critical juncture for UK Defence, where both accelerating delivery and efficient resource use are key.
Says Principeo director Nick Frall, “Johnny and Al have built WM into a strong, flexible and trusted team with client-focus at its core, and unparalleled capabilities in audience analysis and cross-domain, cross-enterprise command and control coherence. This acquisition further strengthens Principeo’s commitment to providing unique value for Defence leaders, and Roland and I are excited to continue and build on the assured delivery which WM clients have come to expect."
Says former Warner McCall director Johnny Norris, “Al and I are delighted to pass the baton to Nick and Roland, and this deal brilliantly combines Warner McCall’s client-focused heritage, capabilities and values with Principeo’s distinctive strategic approach, to enhance a unique offering for Defence leaders.”
As part of the deal, former WM directors Johnny Norris and Al Sweet will cease ownership of WM and step back from management responsibilities, handing over to Nick Frall and Roland Lyle, but remain engaged to ensure a robust transition and continued delivery for all existing clients.
