Utterwick Group plc is listed on the London Stock Exchange. This page provides an overview of the Group's financial performance, equity story and divisional contribution for existing and prospective institutional investors.

Equity story

The Utterwick Group equity story is built on three pillars:

• Diversification across complementary markets. The Group's three divisions — Data & Instrumentation, Environmental and Engineering Solutions — serve different end markets with different demand drivers. Environmental compliance work is largely counter-cyclical and driven by regulatory requirements. Engineering solutions follow infrastructure investment cycles. Instrumentation serves long-term digital transformation programmes in water, chemicals and food manufacturing. This diversity provides resilience and reduces earnings volatility.
• A platform for organic and acquisitive growth. The Group has a track record of building capability through both organic investment and targeted acquisition. The creation of the instrumentation division in 2008, the launch of the carbon and sustainability advisory service within the environmental division in 2021, and the continued modernisation of the engineering facility in Beeston all demonstrate the Group's commitment to investing in its future capabilities.
• Operational discipline and capital efficiency. The Group maintains a disciplined approach to capital allocation, with investment decisions assessed against clear return thresholds and strategic fit criteria. The board's focus on capital discipline has supported consistent margin performance despite variable market conditions.

Divisional contribution

The Group's revenue and operating profit are generated across three divisions, each with its own managing director, market position and growth profile.

Utterwick Data & Instrumentation

Founded within the Group in 2008, the instrumentation division is the smallest by headcount (approximately 280 employees) but represents the Group's highest-growth opportunity. Under the leadership of Sophie Callender, Managing Director, who joined from Renishaw in 2016, the division has established a strong position in industrial sensor technology and cloud-based analytics. Its principal products — the Sondrel sensor platform and Vantage IQ analytics software — serve the water utilities, chemical processing and food manufacturing sectors.

Utterwick Environmental

The founding business of the Group, Utterwick Environmental employs approximately 470 people and provides contaminated land remediation, environmental assessments, groundwater monitoring, permitting and compliance services. The division is led by Claire Doveridge, Managing Director, who joined from Arcadis in 2010. The division's revenue base is underpinned by regulatory requirements and long-term framework agreements with property developers, utilities and public sector clients.

Utterwick Engineering Solutions

The Group's largest division by employee count (approximately 650 people), Engineering Solutions originated from the acquisition of Hartfield & Sons in 1996 and is led by Graham Nettleship, Managing Director, who has been with the company since 1999. The division provides fluid systems engineering, structural steelwork, mechanical and electrical installation, and manufactures the Hartfield Valve Series. It operates from a well-equipped manufacturing facility in Beeston, Nottingham.

Leadership

The Group is led by a board that combines operational experience in industrial services with financial and governance expertise.

Marcus Threlfall, Chief Executive Officer, joined the Group in 2015 as Chief Operating Officer and was appointed to the chief executive role in 2017. He succeeded the company's co-founder Derek Pallister. Threlfall previously held senior positions at Interserve and Amey. Judith Crane, Chief Financial Officer, was appointed in 2019 from Severfield PLC. Raymond Osei, Chief Operating Officer, joined in 2021 from Costain.

The non-executive directors bring independent oversight from relevant sectors. Patricia Vane serves as Non-Executive Chairman (appointed 2020, previously at Augean PLC). Howard Briggs serves as Senior Independent Director (appointed 2018, previously at Eversheds Sutherland). Sunita Mehrotra serves as Non-Executive Director (appointed 2022, previously Chief Digital Officer at Severn Trent).

Corporate heritage

Utterwick Group plc was founded in 1993 by Derek Pallister, a former process engineer at British Coal, and Carolyn Shreve, a chartered accountant who had trained at Ernst & Young in Birmingham. The company name derives from a hamlet near Southwell, Nottinghamshire, where Pallister grew up. From a single environmental consultancy, the Group has grown through organic investment and acquisition to become a diversified industrial services business with approximately 1,400 employees and revenue of £187 million.

Stakeholder engagement

The Group maintains an active stakeholder engagement programme with institutional investors, analysts and proxy advisers. The Chief Financial Officer, Judith Crane, is the primary point of contact for investor relations enquiries.
