Owner dependency
76/100
High — earn-out structure requiredMaterial founder dependency. Consider a 2-3 year earn-out and build in a handover plan before completion.
FACTORS
- +Two-director setup: Only two active directors — typical of owner-managed SMEs but limits succession.
- +Long-tenure founder: Senior director has been in place 20 years — deep operational knowledge concentrated in one person.
- +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.
Succession & seller-readiness
59/100
Strong succession signalMultiple signals suggest succession is on the horizon. Candidate for proactive outreach.
SIGNALS
- secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
- secondary12+ year tenure: Director in role 20 years.
- secondaryStable-but-static management: Company is 20 years old and no new directors in the last 3 years — succession not yet being planned internally.
- supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
Red flags
cleanNo red flags detected from available public data. (This is not a clean bill of health — detailed accounts review still recommended.)
