Owner dependency

76/100
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.
  • +Long-tenure founder: Senior director has been in place 21 years — deep operational knowledge concentrated in one person.
  • +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Succession & seller-readiness

66/100
Strong succession signal

Multiple 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.
  • primary20+ year tenure: Director in role 21 years. Very long tenure is a classic succession signal.
  • secondaryStable-but-static management: Company is 21 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
