Drop us a line

We assist our clients with corporate advisory, project management, strategic reviews and valuation/financial modelling

Our Services

We provide independent corporate advice to our clients, and offer deep experience in:

• energy, utilities and infrastructure

• privatisations (across sectors)

• strategic advice to State Governments, listed and unlisted companies

• valuation and financial modelling of large, long lived complex assets.

We also have experience in healthcare, financial services, private equity and general industry.

While our advisory capability is primarily focused on the energy, utilities and infrastructure sectors in Australia and New Zealand, we have a broad capability across industries and other geographical markets.

We believe that the best outcomes for clients are achieved by embedding ourselves alongside management and building a relationship of trust based on independent, objective and discrete advice. We understand the operational as well as financial issues that arise during transactions and are conscious of the fact that management must live with the consequences of their decisions.

Our model differs from the traditional investment banking model. Our positioning is more akin to an in-house corporate advisory, project management and strategy function and our independence and objectivity aligns us closely with management. We understand the importance of execution and assist in managing all aspects of a transaction, both before and post completion. In this way we tackle the real challenges that face management teams when sourcing and implementing transactions.

One or more of Minerva’s principals undertakes each assignment to provide the best service possible to clients. We do not delegate our responsibilities to less experienced staff.

Our team is made up of highly experienced professionals and support staff, as well as a network of specialist consultants who are engaged on a transaction-by-transaction basis to fit the requirements of our clients:
