Mizuho Financial Group has announced the acquisition of Augusta & Co, a leading European independent financial advisory firm focused on the renewable energy and energy transition sectors.

“We are delighted to announce our planned acquisition of Augusta & Co, which marks an exciting step forward in our strategy to support our clients’ transition towards a low-carbon economy,” said Yutaka Nanjo, Head of Global Investment Banking Division at Mizuho Securities. “Augusta & Co is a leading name in renewable advisory services with extensive relationships with renewables investors. Through this transaction we are combining their specialist expertise with our global reach, client base, and product offering. This is in addition to our well-established and successful global M&A platform, which we bolstered with our acquisition of Greenhill in 2023.”

Mizuho emphasized that the acquisition is directly aligned with the group’s long-term climate goals. Yasuhiko Ushikubo, Chief Sustainability Officer at Mizuho Financial Group, noted: “We are thrilled to announce the acquisition of Augusta & Co. The Mizuho group is deeply committed to supporting our clients’ energy transition journeys by creating new opportunities in the renewable energy sector. Today’s announcement is fully aligned with our group’s sustainability strategy and targets.”

Suneel Bakhshi, President & CEO of Mizuho International and Head of the Corporate and Investment Bank in EMEA, highlighted the operational value Augusta & Co brings: “We are delighted to welcome the talented team at Augusta & Co to Mizuho Financial Group. They provide a full suite of financial advisory services for a wide range of renewable technologies that will enhance our capabilities in the sector. This strengthens our position to become a leading financial institution in sustainable finance and reinforces our dedication to deliver long-term value for our clients and the communities in which we operate.”

Augusta & Co’s Managing Partners, Mortimer Menzel and James Knight, commented on the strategic fit and shared future vision:
“We are proud to have built Augusta over the last 23 years from small beginnings into a leading independent European financial advisor in renewables and energy transition, with a reputation for rigorous client focus and closing complex, structured deals. Together with our partners Simon Clement-Davies, Charlie Hodges, and Romane Guitard and the wider team, we are now taking Augusta to the next level. By combining Augusta’s leading sector expertise with Mizuho’s global reach, deep energy financing, and capital markets strengths, along with a shared vision of a sustainable future, we are excited to embark on the next stage of our growth.”

They added, “As transactions in the renewables sector become more sophisticated and global, they also require more specialist, bespoke advice supported by a wider product base—which will be core to our business model.”

The acquisition represents a strategic expansion for Mizuho into the fast-evolving renewable and energy transition finance space, reinforcing its ambition to become a global leader in sustainable finance.
