Owner dependency

56/100

Moderate — manageable with handover

Some founder dependency, but not acute. A structured handover period should cover most risk.

FACTORS

-6 active directors: Broader management team in place — suggests transferable governance.
+Senior director age: Director aged approximately 58 — approaching natural succession window.
+Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Succession & seller-readiness

45/100

Moderate signal

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

SIGNALS

secondaryFounder aged 58+: Senior director is approximately 58. Early succession window.
supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
