CMS advises Shareholders of Boldt AG on the sale of their shares to BPI
CMS advised the shareholders of BOLDT AG, Zurich, on the sale of their shares to Bully Pulpit Interactive (BPI). BOLDT is a senior-led European business strategy, public policy and communication consulting firm with more than 50 professionals and offices in Berlin, Brussels, Düsseldorf, London, Oslo as well as Zurich and advises some of the world's largest enterprises on their most critical issues. Boldt will keep its branding and become "BOLDT, a BPI Company". Boldt is focused on delivering business strategy, communications, and stakeholder engagement to transform organisations and performance. BPI is a US outcomes agency at the intersection of business, politics, and policy with offices in Chicago, New York, San Francisco and Washington, DC as well as two-time PRovoke Media Global Public Affairs Agency of the Year. In connection with the transaction, BPI will rebrand as Bully Pulpit International. With the acquisition of BOLDT, BPI enters into the European market and can offer to the customers of the combined enterprise transatlantic services. The combined company will have more than 250 employees in 10 offices in 6 countries. Against the background of pivotal elections in both the U.S. and Europe next year, the world’s most influential leaders and brands need a single best-in-class partner that can deliver a coherent bilateral strategy. With this investment, BPI introduces a bilateral public affairs, campaigning, and strategic communications offering to serve both American and European clients. As the pace of change increases, policy discussions evolve, and stakeholders demand engagement, brands require a cohesive approach across policy and corporate strategy in the U.S. and Europe. For Jeremy Galbraith, Managing Partner of BOLDT, it is an ideal time for BOLDT and BPI to join forces, given the political landscape and the pressures that businesses face to transform in Europe and in the U.S. BPI's and Boldt's service offering and culture are a natural fit. The introduction between BPI and BOLDT, which ultimately culminated in the acquisition of Boldt by BPI, was made by Jon Banner, Global Chief Impact Officer of McDonald's.A CMS team led by Daniel Jenny provided comprehensive legal advice to the shareholders of BOLDT AG in connection with the transaction.
