Current portfolio

Overview

DNS:NET is a leading independent telecommunications provider in Germany. Established in 1998, DNS:NET owns the largest independent fibre-to-the-cabinet network in the Berlin area and is rolling out a fibre-to-the home network in Berlin and the surrounding regions.

The company differentiates itself through a superior network, local brand recognition and attractive pricing of high bandwidth products, which drives high customer satisfaction. 3i Infrastructure’s backing will allow DNS:NET to accelerate its build programme to provide gigabit-ready connectivity to its customers. 

Recent Developments

DNS:NET received investment of £34 million during the year from 3iN to continue the development of its FTTH network in areas around Berlin and in the State of Brandenburg. A new CEO joined DNS:NET in July 2023. He has overseen the preparation of an updated business plan that was agreed with shareholders in December 2023. We are making good progress in building a strengthened and experienced management team.

FTTH network rollouts in Germany remain challenging. Passing homes has been the industry’s primary focus to date. Connecting and activating customers to the network on a timely basis is an industry-wide challenge. The negative value movement in the year was driven by more conservative business plan assumptions for DNS:NET’s FTTH rollout. Throughout the year, DNS:NET has focused on connecting backbone fibre infrastructure and home connections for its owned network, as well as on securing the handover of leased networks built by authorities in the neighbouring State of Saxony-Anhalt, making good progress in the number of its connected and activated customers as a result.

The company is now preparing for the next stages in its network delivery in a way that narrows the time lag between passing homes and connecting and activating customers on that FTTH network to improve performance. We have increased the discount rate to reflect uncertainties over available debt pricing for fibre businesses in future years and the delay against the original rollout timetable.

Overview

Headquartered in Esbjerg, Denmark, ESVAGT is the market leader in the fast-growing segment of service operation vessels (“SOV”) for the offshore wind industry. The Company is also a leading provider of emergency rescue and response vessels (“ERRV”) and related services to the offshore energy industry in and around the North Sea and the Barents Sea.

ESVAGT is the pioneer and market leader in the provision of SOVs to offshore wind farms, with nine bespoke vessels in operation and a further four under construction. SOVs are purpose-built, high performance vessels, providing efficient transport of maintenance technicians to wind turbines and other offshore wind equipment, under long term contracts. The offshore wind market, and hence demand for SOVs, is expected to grow strongly over the coming years, creating significant opportunities for the company.

Its ERRV services mainly involve the rescue and recovery of personnel, but also include the dispersion and recovery of oil spills, crew transfers and towing. ESVAGT is the leading provider of ERRV services in Denmark and Norway, with market shares of approximately 100% and 50%, respectively, as well as an established and growing presence in the UK. The majority of ESVAGT’s ERRV revenues are associated with North Sea oil and gas production support, with the remainder generated by supporting exploration activity.

ESVAGT has been operating since 1981, employs over 1,100 people and owns a fleet of more than 43 vessels.

Recent developments

ESVAGT performed well in the year, benefitting from strong contract rates and high utilisation levels. As the clear market leader in European offshore wind SOV provision, ESVAGT currently operates nine vessels. A further four SOVs are under construction, specifically designed to serve long-term charter agreements, and construction progress is on track. Despite inflationary pressure causing delays and cancellations in wind farm development, regulators and governments have become more supportive of incentivising growth in offshore wind.

Inflation, while negatively impacting the construction cost of the near-term pipeline, has a positive effect on ESVAGT due to its index-linked contracts, which enhance the value of its operational SOV fleet. The offshore wind market remains on a positive trajectory and this is reflected in the pipeline for additional new SOVs in the

North Sea and the rapidly expanding US wind market. Over the next 12 months, we anticipate several tenders to take place.

ESVAGT’s ERRV segment also maintained positive momentum, driven by favourable supply/demand dynamics, and an increased emphasis on security of supply in Europe.

Overview

Future Biogas is one of the largest anaerobic digestion (AD) plant developers and biogas producers in the UK. It owns two AD plants with one further AD plant in construction, and operates 10 AD plants mainly on behalf of institutional investors under medium-long term contracts.

Future Biogas’s plants convert a wide range of feedstocks into clean and renewable energy through AD which produces biogas. Biogas can either be used to generate green electricity, or upgraded into biomethane and injected into the UK’s national gas network. Future Biogas produces over 500GWh of biogas per year, enough energy for over 40,000 homes.

Biomethane from AD is a ready-to-use and commercially viable solution for hard to decarbonise industrial sectors. It does not require any upgrade to the existing UK gas infrastructure. Energy produced by AD plants is carbon neutral, as the CO2 released during the process matches the CO2 absorbed from the atmosphere by the feedstock.

Future Biogas promotes a regenerative farming approach, sustainably integrating feedstock from energy crops into agricultural systems. The circular process of returning digestate back to land can help replenish soil nutrients and carbon and displaces demand for carbon intensive artificial fertilisers.

Recent developments

Future Biogas performed in line with expectations due to good services revenues and index-linked contracts. The company has a promising pipeline of organic growth and M&A opportunities.

During the year, Future Biogas signed a new 15-year gas supply agreement with AstraZeneca (‘AZ’) for unsubsidised green gas. To deliver this green gas, it is constructing the UK’s first unsubsidised AD plant. In September 2023, 3iN invested £35 million to fund the plant’s construction, which will supply 100GWh of biomethane to AZ’s UK sites.

In November 2023, 3iN invested a further £30 million to fund the acquisition of two AD plants that Future Biogas was already managing. These strategic investments continue to transition Future Biogas from a manager of third-party biogas plants to a leading developer, asset owner and operator. The company is actively exploring viable sites for constructing new AD plants, and the interest from high-quality corporate partners is encouraging.

Overview

Oystercatcher is the holding company through which the Company holds a 45% interest in Advario Singapore Limited (previously Oiltanking Singapore Limited).

Advario Singapore is a 1.3 million cubic metre facility focused on storage and blending of refined clear petroleum products for a range of blue chip customers. With a premier location, on Jurong Island, it is accessed by pipeline, sea going vessel and barge.

Oiltanking is one of the world’s leading independent storage partners for oils, chemicals and gases, operating 41 terminals in 18 countries with a total storage capacity of 16 million cubic metres.

Recent developments

Oystercatcher performed well in the year. Advario Singapore, which is 45% owned by Oystercatcher, benefitted from high utilisation levels for its storage capacity, high customer activity levels and higher rates being secured at contract renewal. Whilst the oil products market remains in backwardation, a tight storage market in Singapore and the wider region provided a helpful backdrop to renewal discussions. Advario Singapore remains the leading gasoline blending facility in Singapore and the wider region.

The company has continued to pursue opportunities linked to sustainable fuels, in line with its sustainability strategy. Building on its success to date with Neste, which is blending sustainable aviation fuel (‘SAF’) at Advario Singapore, the terminal had actively looked to expand its role in activities to supply sustainable transport fuels.

Overview

Furthermore, Tampnet is actively engaged in carbon capture and offshore wind projects within its existing network in the North Sea. The business was awarded its first offshore carbon sequestration connection in March 2024. The potential for further comparable initiatives is substantial and Tampnet is strategically positioned to contribute to their success.

Overview

Headquartered in Brussels, Belgium, TCR is Europe’s largest independent asset manager of airport ground support equipment (“GSE”). It operates at more than 210 airports across more than 20 countries. Since inception, TCR has defined the market for leased GSE, providing high quality assets and a full service leasing, maintenance and fleet management offering to its clients, which are predominantly independent ground handling companies, airlines and airports. This enables GSE operators to concentrate on their core business of ground handling.

TCR’s GSE is the essential mobile infrastructure used to service aircraft on the ground and enable airports to handle passengers, luggage and cargo, with upwards of 30 pieces of equipment required per turnaround. Reliable GSE is critical to the smooth operation of airports and timely movement of aircraft, and TCR is able to deliver this with its access to scarce airside repair workshops, which provides a high barrier to entry. Sustainability is at the heart of the business and its mission is to deliver the most efficient and sustainable GSE services. Through its expertise in GSE fleet optimisation, “pooling” initiatives and the provision of green GSE, TCR is playing a key role in enabling the decarbonisation of airport ground operations in the airports where it operates.

Recent developments

TCR materially outperformed expectations, resulting in a substantial increase in value by £92 million. This performance was driven by several factors, including significant contract wins, extensions and higher fleet utilisation rates. The company is benefitting from the combination of the post-Covid aviation recovery, high interest rate environment making on-balance sheet options less attractive for customers, and the green agenda in Europe driving strong demand for new electric ground service equipment.

In February 2024, TCR completed the bolton acquisition of KES, KLM Royal Dutch Airline’s ground equipment services subsidiary at Schiphol airport, adding incremental contracted EBITDA with a flagship European carrier and positioning TCR to support Schiphol’s decarbonisation ambitions. TCR’s footprint now spans more than 200 airports, positioning it well to grow organically with its existing clients as well as increasing market penetration of its full-service rental offering. To support its next phase of expansion, TCR successfully secured additional debt from existing and new lenders on attractive terms.

Overview

Valorem is a leading independent renewable energy development and operating company. It is one of the largest onshore wind developers in France, having developed over 600MW of capacity over the last 10 years.

The French power market is experiencing a major transition as it looks to reduce its reliance on nuclear generation and to increase generation from renewable sources of energy such as wind and solar. The energy transition has been continuously supported by the French governments over the past decade. With in-house capabilities across the entire project cycle and a strong local footprint, Valorem is well positioned to benefit from this shift in energy mix.

Recent developments

Valorem had a very good year with revenues from electricity generation ahead of expectations due to favourable wind conditions contributing to a value gain of £47 million. The company’s closed capacity now totals 853MW of wind, solar and hydro projects, a 10% increase from the previous year.

Valorem completed the sale of a minority stake in part of its French operational portfolio on attractive terms, demonstrating the strong appetite for its projects and raising capital to finance development of future projects. This was supplemented by issuance of euro private placement debt for the first time.

In France, the market fundamentals for renewable developers remains strong, as evidenced by the increase in recent auction tariff levels due to demand for projects exceeding supply. The construction of Valorem’s new projects in Finland and Greece are progressing according to or ahead of plan. The company has expanded its development pipeline from 5.7GW to 6.6GW, including securing partnerships for co-developments in Poland and Sweden.
