Owner dependency

65/100
High — earn-out structure required

Material founder dependency. Consider a 2-3 year earn-out and build in a handover plan before completion.

FACTORS
  • -6 active directors: Broader management team in place — suggests transferable governance.
  • +Long-tenure founder: Senior director has been in place 31 years — deep operational knowledge concentrated in one person.
  • +Founder age: Director aged approximately 77 — succession pressure is live.

Succession & seller-readiness

80/100
Likely off-market candidate

Strong acquirability signals converging. Worth approaching directly — this is how off-market deals start.

SIGNALS
  • primaryFounder aged 70+: Senior director is approximately 77 years old. Natural succession window is now.
  • primary20+ year tenure: Director in role 31 years. Very long tenure is a classic succession signal.
  • supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
