Investment thesis
Zombie company — trading but stalled; unlikely mover.

What this business does
Primary activity: SIC 33190
Sector: Manufacturing
Investor take
PursueActive trading company with a 77-year-old founder — textbook succession opportunity.
Opportunity 82/100 (exceptional), bankability 80/100. Strong seller-intent signal (83/100, director aged 77). Share purchase looks the cleaner deal structure. Biggest value-creation lever: Discharge stale live charges. 1 live charge(s) created 15+ years ago — likely paid but undischarged. Clean register. Most likely exit: share sale to pe / searcher (73/100).
🏦
Refinance opportunity
1 live charge · oldest 23.9y
45/100
under pressure
Refinance would be pressure-driven, not opportunity-driven. Expect tighter margins and covenant scrutiny.
- · Oldest live charge is 23.9 years old — likely at or near maturity.
- · Single lender — cleanest path to refinance.
- · Distress signals active — lender appetite narrows.
Data confidence
Overall: medium (76/100)Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.

Owner dependency
100/100
Critical — business is the founderThe business appears inseparable from the founder. Acquisition without a serious earn-out or meaningful transition period would likely destroy value.
FACTORS
- +Sole director: Only one active director — all governance concentrated on one person.
- +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.
Succession & seller-readiness
100/100
Likely off-market candidateStrong 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.
- primarySole active director: Only one director in control. No visible successor — buyers solve the succession problem.
- 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.
- supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
