What this business does

Primary activity: SIC 33190

Sector: Manufacturing

Investor take

Pass (distressed without resilience)

Distressed active trading company — structural issues outweigh the discount.

Opportunity 73/100 (strong), bankability 65/100. High owner-dependency — earn-out structure likely required for clean transition. Biggest value-creation lever: Resolve: Confirmation statement overdue. Annual confirmation statement not filed on time. Required statutory filing — overdue is a strong discipline signal. Most likely exit: share sale to pe / searcher (65/100).

Data confidence

Overall: medium (68/100)

Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.

Owner dependency

75/100

FACTORS

+Long-tenure founder: Senior director has been in place 25 years — deep operational knowledge concentrated in one person.
+Founder age: Director aged approximately 77 — succession pressure is live.

85/100

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 25 years. Very long tenure is a classic succession signal.
secondaryStable-but-static management: Company is 25 years old and no new directors in the last 3 years — succession not yet being planned internally.

Red flags

1 high ·
