Owner dependency

68/100
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 16 years — deep operational knowledge concentrated in one person.

Succession & seller-readiness

49/100
Moderate signal

Some succession indicators present. Worth watching; approach if sector/strategy fits.

SIGNALS
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
  • secondary12+ year tenure: Director in role 16 years.
  • supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
