Insights

Insurance Focus Stonybrook operates as a specialist advisory and investment bank focused exclusively on the insurance industry, serving insurers, reinsurers, agents, brokers, MGAs, asset managers, private equity firms and hedge funds. This deep vertical reach enables tailored capital structures, fundraising and M&A guidance aligned with sector-specific dynamics.

Capital Markets Momentum Recent activity demonstrates capacity and appetite for insurance-sector capital solutions, including advising MMG Insurance on a 35 million dollar senior unsecured note and signing a new client. This track record positions the firm to pitch additional debt, equity and hybrid capital raises to similar insurers and related buyers.

Strategic Growth Leadership changes and new client wins indicate expansion and increased capability for international and mid-market mandates. Notable developments include the appointment of Darren Bailey as CEO of international and group MD, and the addition of Peter McGuire to the board, signaling broader capacity for strategic advisory and fundraising.

Reinsurance Expertise The ILW desk and related reinsurance and insurance-linked securities (ILS) expertise highlight a strong niche in risk transfer structures and capital-relief strategies, attracting reinsurers, ILS funds and MGAs seeking specialized advisory and capital-market solutions.

NAMIC Advantage As the first and only investment bank affiliated with NAMIC, Stonybrook Capital gains credibility and access to NAMIC’s network of mutual insurers and affiliated firms, creating a valuable channel for sourcing opportunities within the mutual and regional insurer market.
