Active asset management

We create value from our investments through the Investment Manager’s active asset management approach. Through this approach, the Investment Manager partners with our portfolio companies’ management teams to develop and execute a strategy to create long-term sustainable value. Examples of this partnership include: developing strategies that support investment in the portfolio company’s asset base over the long term; continued improvements in operational performance; and establishing governance models that promote an alignment of interests between management and stakeholders. We develop and supplement management teams, often bringing in a non-executive chair early in our ownership.

  • Strengthen portfolio company management teams
  • Invest in and develop companies with a clear strategy
  • Grow our platform businesses through further investments
  • Dedicated ESG team

Q&A

with 3i Investments Partner Anna Dellis

Where do you see sustainability creating the most value for the 3iN portfolio?

Our portfolio companies are identifying and pursuing opportunities to support their customers to meet their own decarbonisation ambitions and to participate in the energy transition. With our capital and expertise, we help them capture these opportunities. TCR is supporting its customers to increasingly use ground support equipment powered by electricity; ESVAGT and Tampnet are supporting the offshore wind sector and the emerging carbon capture and storage sector; Infinis is investing in solar energy generation; Future Biogas is supporting corporates like AstraZeneca to procure energy created by biogas; Oystercatcher’s storage terminal in Singapore is storing and blending sustainable aviation fuel for Changi Airport as well as for export to other countries.

In March 2024, the SBTi validated 3i Group’s emissions reduction targets. Has 3iN’s portfolio made progress on target setting since then?

We want our portfolio companies’ targets to be credible and underpinned by a plan that management can follow and be confident it can deliver. Since March 2024, Joulz and Ionisos have secured SBTi validation of their targets, and SRL and TCR have submitted targets for validation. We are now leveraging the experience and learnings of these first movers for the benefit of other portfolio companies. In this way we support portfolio companies that, due to their size for example, might not otherwise have been in a position to commit to a science-based target, to be able to do so. This demonstrates a real benefit of 3iN ownership for our portfolio.

How does 3iN drive improvements in health and safety performance across its portfolio?

We expect that health and safety is at the top of the board agenda. We ensure that portfolio company board reporting is fit for purpose and includes leading indicators, such as near misses, to allow effective oversight of health and safety risk and accident prevention. 3iN’s representatives on portfolio company boards receive health and safety training to increase their effectiveness in this role. We believe it is critical that they lead by example – showing management teams and employees that health and safety is a key priority for 3iN.

Our strategic ESG focus areas

Carbon and climate

Climate change and the transition to the low-carbon economy are significant macroeconomic trends impacting the sectors in which we invest.

In March 2024, 3i Group plc set science-based emissions reduction targets, which were validated by the SBTi. These targets cover both direct emissions and downstream indirect emissions associated with all the portfolio companies that 3i manages. Throughout the year, the Investment Manager has communicated these targets to portfolio companies and has supported them in developing the business case for setting their own science-based emissions reduction targets.

Planned next steps for FY26
  • Continued one-on-one engagement with portfolio companies on emissions data quality, Scope 3 and setting science based emissions reduction targets
  • Continue engaging with portfolio companies on the incorporation of climate risks into their strategy and risk management
