About Us

ICA Partners is one of Australia’s leading boutique advisory firms.

In 2012, Ironstone Capital Advisory was established by Michael Siede, Aaron Simcock and Greg Arandt. Alistair Craib also joined in 2013.

ICA Partners was the top financial advisor by deal value for 1H19, and was second in the number of transactions completed in 2018 in the Australian Power, Energy and Renewables sector (source: Inframation).

Ironstone Capital Advisory has recently rebranded to ICA Partners. The rebrand is a consequence of the firm’s evolution and is reflective of the significant transformation underway across the energy, resources and infrastructure industries.

In addition to our market leading advisory service and given broad sector participation and industry connections, we can provide unique solutions to clients. One example of this is the initiative with Warada Capital, which provides financing and development capital to assist clients (for more information see www.warada.com.au).

ICA Partners is also at the forefront of exploring opportunities to leverage our renewables and mining expertise to assist infrastructure and mining clients move towards clean energy solutions.
