Mizuho Financial Group has announced an agreement to acquire Augusta & Co, a UK-based independent financial advisory firm specialising in renewable energy and the energy transition sector. The transaction, expected to close by October 2025 pending regulatory approval, will see Mizuho acquire 100% of Augusta & Co’s equity shares and integrate its advisory team into the group.
The acquisition excludes Augusta & Co’s asset management business, which will remain separate. However, the firm’s brand and leadership will be retained following the deal. The move aims to bolster Mizuho’s mergers and acquisitions (M&A) advisory platform and expand its credentials in sustainable finance, both in Europe and globally.
Yutaka Nanjo, Head of Global Investment Banking at Mizuho Securities, described the acquisition as a key strategic step in supporting clients’ low-carbon transitions. “Augusta & Co is a recognised leader in renewable advisory services with strong relationships across the investor landscape,” he said. “Their sector expertise, combined with Mizuho’s global reach and client base, will significantly enhance our advisory capabilities.”
Yasuhiko Ushikubo, Chief Sustainability Officer of Mizuho Financial Group, added that the acquisition aligns closely with Mizuho’s broader sustainability strategy, noting the firm’s commitment to enabling clients’ energy transition journeys.
Suneel Bakhshi, President and CEO of Mizuho International, highlighted the operational and strategic value of the deal: “Augusta & Co’s experience in delivering advisory services across a wide spectrum of renewable technologies will reinforce our position in sustainable finance and help deliver long-term value for our clients and communities.”
Founded over two decades ago, Augusta & Co has developed a reputation for advising on complex, structured deals within the renewables sector. Managing Partners Mortimer Menzel and James Knight, along with fellow partners Simon Clement-Davies, Charlie Hodges, and Romane Guitard, expressed enthusiasm about the next phase of growth under Mizuho’s ownership. “As transactions in the renewables sector become more sophisticated and global, they require more specialist advice and access to a wider product base—core to our future strategy,” they stated.
Following its 2023 acquisition of U.S. investment bank Greenhill, Mizuho continues to expand its global M&A advisory offering with a focus on the growing market for energy transition finance.
