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 26 years — deep operational knowledge concentrated in one person.
+Founder age: Director aged approximately 75 — 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 75 years old. Natural succession window is now.
primary20+ year tenure: Director in role 26 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.

Red flags

clean

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