Owner dependency

73/100
High — earn-out structure required

Material 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 65 — succession pressure is live.

Succession & seller-readiness

66/100
Strong succession signal

Multiple signals suggest succession is on the horizon. Candidate for proactive outreach.

SIGNALS
  • primaryFounder aged 63+: Senior director is approximately 65. Approaching typical UK retirement age — succession thinking likely.
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
  • secondaryStable-but-static management: Company is 29 years old and no new directors in the last 3 years — succession not yet being planned internally.
