Aventum Group has acquired Rotterdam-based Post & Co, marking the specialty re/insurance group’s first managing general agent (MGA) acquisition and its entry into Continental Europe.
The London-headquartered group announced the deal on Tuesday, describing it as a defining step in its ambition to build the world’s leading independent specialty MGA platform. Financial terms were not disclosed. The transaction remains subject to customary regulatory approvals.
Post & Co, a specialist marine and logistics MGA, was founded in 1918 and has remained family-owned for more than a century. The business operates across four offices in Rotterdam, Groningen, Antwerp, and Frankfurt, offering marine insurance lines that include protection and indemnity, charterers’ and shipowners’ liability, war risk, cargo, and logistics-related covers. It distributes through a network of about 250 brokers across Europe and Asia, supported by Lloyd’s and specialist company market capacity.
Aventum said the acquisition serves three strategic purposes: establishing an operational footprint across Continental Europe, strengthening its global marine underwriting proposition, and aligning with a business whose independent, family-owned heritage reflects Aventum’s employee-owned structure. Post & Co will operate within Aventum’s existing MGA arm, Rokstone, which already has marine operations in North America, the UK, and Asia.
The group said no changes will be made to Post & Co’s management or organisational structure. Founder Roderick Post remains a senior member of the leadership team and will lead development of the enlarged group’s Continental European platform and marine proposition.
David Bearman, chief executive of Aventum, said the deal reflected the group’s financial independence in pursuing acquisitions. “Aventum is in a prime and enviable position – we’re independent with significant financial firepower that’s not constrained by punishing debt,” Bearman said. “That gives us the freedom to explore M&A opportunity in an environment where others are retreating.”
Bearman described Post & Co as “a business of the highest calibre,” adding that its leadership’s “experience and standing in the European MGA market will be invaluable.”
Post said the decision to find a long-term partner was approached “with considerable care”. “Aventum’s values, its commitment to independence, to its people and to its ambition, align closely with everything Post & Co stands for,” he said.
Fenchurch Advisory Partners acted as exclusive financial adviser to Aventum on the transaction.
The acquisition builds on a period of sustained marine expansion at Rokstone. In June last year, the MGA launched what was described as Singapore’s first Marine MGA, backed by a multi-year US$25 million Lloyd’s capacity deal, with a target of US$50m in gross written premium within five years.
