South East accountancy, tax and advisory firm HaysMac has acquired a corporate finance advisory practice as it marks 25 years in business.
Joining the firm is Green Square, which brings more than 20 years’ experience advising on transactions across a range of ownership structures – including founder-led and investor-backed businesses.
Green Square is known for its work in the marketing, media and technology sectors, but its expertise spans a variety of cross jurisdiction transactions and commercial environments.
In joining HaysMac, the firm will provide clients with a single, joined-up advisory service, from early preparation and strategic planning through to transaction execution and post-deal outcomes.
Tony Walford and Barry Dudley, partners at Green Square, said: “Green Square has always been focused on helping founders and shareholders make confident decisions at pivotal moments in their lives.
“Joining HaysMac allows us to build on that purpose, working as part of a larger advisory firm that shares our commitment to quality, relationships and long-term outcomes.
“Together, we can support more businesses across a wider range of situations, with the depth and breadth of expertise that clients increasingly value.”
Jon Dawson, partner and head of sectors and markets at HaysMac, said: “Bringing Green Square into the firm broadens the advice we can offer ambitious businesses and investors.
“It embeds dedicated transaction expertise within HaysMac and enhances how we support founders, leadership teams and stakeholders across a wider range of situations and growth stages.”
Natasha Frangos, managing partner at HaysMac, added: “This acquisition is an important milestone for HaysMac and achieves our strategic ambition to deepen our transaction advisory capabilities.
“We have known and worked with the team at Green Square for many years, and so I know our culture and values are aligned.
“Green Square has an outstanding reputation for supporting owners and shareholders through complex, high-value transactions, and their expertise perfectly complements our existing strength in advising growth focused and investor backed businesses.
“Bringing Green Square into the firm builds on what we already do best – combining rigorous thinking with a genuinely people-centred approach.
HaysMac also acquired the US tax team of Moore DM this February.
