Mizuho Financial Group, Inc.; Mizuho Securities Co., Ltd.; Mizuho International plc; and Augusta & Co Limited announce that Mizuho has agreed to acquire Augusta & Co, a leading independent specialist financial advisory firm serving the renewable energy and energy transition sector.

Mizuho will acquire 100% of the equity shares of Augusta & Co and will bring on board Augusta & Co’s employees in the advisory business. The Augusta & Co brand will be maintained, and the existing leadership will remain in place. Augusta & Co’s asset management business is not part of the transaction.

Through this strategic transaction, Mizuho will further strengthen its M&A advisory platform and energy transition credentials in the region and beyond, offering specialized renewable and transition advisory services to clients, leveraging the expertise of Augusta & Co as a leader in this field.

Following the completion of the transaction, Augusta & Co will complement the existing global M&A advisory services provided elsewhere within the Mizuho group.

Commenting on the announcement, Yutaka Nanjo, Head of Global Investment Banking Division, Mizuho Securities, said: “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. 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.”

Yasuhiko Ushikubo, Chief Sustainability Officer, Mizuho Financial Group, added: “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.”

President & CEO of Mizuho International and Head of the Corporate and Investment Bank in EMEA Suneel Bakhshi also commented: “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.”

Managing Partners of Augusta & Co, Mortimer Menzel and James Knight, commented: “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. 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 transaction is expected to close by October 2025 and is subject to regulatory approvals.
