Showing most recent 50 of 69 events

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

+Two-director setup: Only two active directors — typical of owner-managed SMEs but limits succession.
+Founder age: Director aged approximately 66 — succession pressure is live.

Succession & seller-readiness

56/100

Strong succession signal

Multiple signals suggest succession is on the horizon. Candidate for proactive outreach.

SIGNALS

primaryFounder aged 63+: Senior director is approximately 66. Approaching typical UK retirement age — succession thinking likely.
secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.

Red flags

1 med ·

6 director resignations in last 12 months

medium

Multiple recent departures can indicate governance disagreement, succession event, or preparation for sale/stress.

Evidence: COPE, Barry Paul resigned 2025-06-30; KNIGHTS, Christopher Leslie resigned 2026-02-26; LANE, Andrew John resigned 2026-02-26
