What Augusta & Co does

Augusta & Co is a London-headquartered specialist financial advisory firm serving the European renewable energy and energy transition sector. Founded in 2002 by senior bankers from leading investment banks, the firm provides M&A advisory, debt advisory, strategic advisory, equity capital markets, power purchase agreement (PPA) services and specialised consultancy across clean energy generation (onshore wind, offshore wind, solar PV, hydro), energy storage (BESS, pumped hydro), power-to-X (green hydrogen, sustainable aviation fuel, carbon capture), data centres and supply chain. The firm serves developers, independent power producers, utilities, industrial companies and investment funds, and reports having raised €21 billion in equity, advised on €5+ billion in debt, facilitated €2 billion in non-dilutive growth capital and transacted over 40GW of clean energy across 160+ deals since inception.

The firm's commercial model is project-based professional services: revenue is generated from advisory fees negotiated transaction-by-transaction, with no publicly disclosed pricing or recurring revenue component. Augusta maintains relationships with over 1,200 investors and lenders globally, including 150+ lenders with which it places debt. Its go-to-market is sales-led and direct, originating mandates through sector reputation, banker-led relationships and industry event participation rather than mass marketing. The firm is regulated by the UK Financial Conduct Authority and is authorised as a private limited company registered in England.

In 2025, Augusta & Co was acquired by Mizuho Financial Group, integrating the specialist renewables franchise into a global banking platform. Following the acquisition, the firm operates as Mizuho's financial advisory platform for renewable energy and the energy transition in Europe and beyond, retaining its brand identity while gaining access to Mizuho's international capital markets capabilities and cross-border distribution. The firm employs 11-50 staff organised in a pyramid from Managing Partners and Partners through Managing Directors, Directors, Associate Directors, Associates and Analysts, with a stated headcount described as "one of the largest specialised teams in the clean energy sector."
