Owner dependency

74/100
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.
  • +Senior director age: Director aged approximately 61 — approaching natural succession window.
  • +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Succession & seller-readiness

46/100
Moderate signal

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

SIGNALS
  • secondaryFounder aged 58+: Senior director is approximately 61. Early succession window.
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.

Red flags

No red flags detected from available public data. (This is not a clean bill of health — detailed accounts review still recommended.)
