Transactional Due Diligence Assessments

ESG risks RiskHorizon data

RiskHorizon, created by Anthesis, is a purpose made tool for use in the environmental due diligence (EDD) process. It is specifically aimed at helping legal advisors, investors, acquirers, finance professionals and deal makers identify the material ESG risks and opportunities at an early stage of the deal cycle and take full account of the relevant issues throughout the transaction life cycle.

In an increasingly complex and regulated world, where sustainability issues present both risks and opportunities, transactional due diligence needs a deal-specific approach that addresses both conventional compliance and legacy liabilities, as well as sustainability performance and preparedness for the future.

We deliver full due diligence assessments for both vendors and acquirers. Our offer spans from the traditional environmental, health and safety (EHS) risk such as contaminated land, across the full range of environmental, social and governance (ESG) issues.

Our experience is global, covering nearly all commercial and industrial sectors from software to oil and gas, and ranges from advising on small single-site, bolt-on transactions to complex multi-site, multi-jurisdictional businesses.

We understand the differing approaches required depending on the deal structure, for instance the nuances of how to interact with the other side depending on whether the transaction is exclusive or a competitive auction.

Our advice is always commercially astute, seeking to contextualise the issues identified with narrative on the likelihood of the issue arising, timescales and the potential cost implications. Where an issue presents a potential hurdle to the smooth completion of the transaction, we will always seek to identify solutions.

Our advice is also always backed by appropriate levels of professional indemnity insurance cover, disclosure and reliance arrangements.

I have worked with Anthesis for many years. They have a depth of ESG understanding and expertise, allowing real analysis and advice on the emerging issues that are becoming increasingly material to our clients. What sets them apart is their willingness and ability to apply this, together with technology solutions, to enhance the quality and speed of their reporting.

We wanted the ESG screen as we were keen to understand the definition of ESG and to see the criteria you would be using. We were also interested to see how others would view us through this lens. The Anthesis screen provided us a with a “mirror”. The value to Neste was that it confirmed we are on a right track to addressing ESG issues. It also helped us to identify some potential improvement opportunities, several of which we are working on, and others that warrant further evaluation.
