Company Descriptions
Nexus Infrastructure, via its principal trading business Tamdown, is a leading provider of civil engineering services, principally to major housebuilders. The group is also aiming to expand its activities to critical infrastructure. Activities comprise a wide range of civil engineering services, including earthworks, roads, drainage, waste management, mainly used early in the opening of new housebuilding sites, and providing foundations for individual new homes. Clients include the UK's top five listed housebuilders - Barratt Developments, Vistry Group, Taylor Wimpey, Persimmon and Bellway - as well as leading private groups including Bloor Homes, partnership specialist Keepmoat and housing associations. The group operates mainly in London and the South East. The group has been operating for over 45 years. In February 2023, it completed the disposal of TriConnex and eSmart Networks to private investment group FitzWalter Capital for a cash consideration of £78m; c. £61m was subsequently returned.
Investment Summary
Nexus Infrastructure should be an early beneficiary of the new government’s plans to build 1.5 million homes over the life of the parliament, as the group has refocused the business on ‘front end’ civil engineering activities for the UK’s largest housebuilders. After aligning the cost base in the face of sector and economic headwinds over the past year, our initial estimates indicate the group should return to modest profit by FY25E. Thereafter, operational gearing could offer substantial earnings growth under a range of scenarios. We believe housebuilding and broader infrastructure activities could offer multi-year opportunities. Over the medium term, the group is considering diversifying into vital infrastructure. Of this, water supply and sewage, flood protection and energy are urgent national priorities. Longer term, a major opportunity could be Labour’s plans for ‘new towns’, given Tamdown’s experience in large, complex sites.
