Screening memo
Corvane Analytical Group
4 September 2026 · Version 1 · Draft
The opportunity
Ashby Ridge Partners has agreed to acquire Corvane Analytical Group, an independent environmental, food and water testing laboratory network in the UK and Ireland, from its founder and a minority investor at an enterprise value of £326m (12.0x FY25 EBITDA). We are invited to provide a £150m seven-year unitranche alongside one other lender, with a £35m committed acquisition and capex facility. Indicative pricing is SONIA + 5.75% with a 98.0 OID.
Business overview
Corvane runs 14 accredited laboratories testing water, soil, air and food samples for utilities, local authorities, contractors and food producers. FY25 revenue was £118.4m and EBITDA £27.2m, a 23.0% margin, having grown 13% a year since FY23, roughly two thirds organically and one third through five bolt-on acquisitions.
Key merits
- Non-discretionary demand: testing is required by regulation and permit conditions, not by the economic cycle.
- Recurring revenue: 68% of revenue is earned under multi-year framework contracts with utilities and public bodies.
- Strong cash generation: capex of £6.1m in FY25 gives cash conversion of 78% of EBITDA.
- Meaningful equity cushion: sponsor equity of £190m, 56% of total sources.
Key risks
- Thin interest cover at entry: 1.9x, leaving limited room if base rates rise. Mitigant: hedging of at least two thirds of the unitranche to be required.
- Customer concentration: the top ten customers are 31% of revenue and the largest water utility 7%.
- Buy-and-build execution: further acquisitions funded by the CAF add integration risk. Mitigant: CAF draws subject to a leverage test.
- Accreditation: losing UKAS accreditation at a large laboratory would stop testing there until restored.
