Owner dependency

73/100

High — earn-out structure required

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

FACTORS

-4 active directors: Broader management team in place — suggests transferable governance.
+Founder name in company name: Company name contains director surname "MCDERMOTT" — strong identity link between founder and business.
+Long-tenure founder: Senior director has been in place 25 years — deep operational knowledge concentrated in one person.
+Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Succession & seller-readiness

50/100

Moderate signal

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

SIGNALS

primary20+ year tenure: Director in role 25 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.)
