Owner dependency
73/100
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.
- +Founder age: Director aged approximately 71 — succession pressure is live.
Succession & seller-readiness
76/100
Likely off-market candidateStrong acquirability signals converging. Worth approaching directly — this is how off-market deals start.
SIGNALS
- primaryFounder aged 70+: Senior director is approximately 71 years old. Natural succession window is now.
- secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
- secondaryStable-but-static management: Company is 37 years old and no new directors in the last 3 years — succession not yet being planned internally.
