What this business does
Primary activity: Activities of head offices
Sector: Professional, scientific & technical
Investor take
Pass (distressed without resilience)Distressed unclear — structural issues outweigh the discount.
Opportunity 51/100 (worth a look), bankability 50/100. Asset purchase likely safer than share purchase given structural signals. Biggest value-creation lever: Resolve: Company dissolved. Company has been dissolved — it no longer legally exists. Any diligence here is historical only. Most likely exit: strategic trade sale (53/100). Current lenders should be on monthly review.
Data confidence
Overall: low (52/100)Sparse data coverage. Treat AI-generated outputs as preliminary. Manual diligence essential.

- +Senior director age: Director aged approximately 61 — approaching natural succession window.

- secondary12+ year tenure: Director in role 15 years.
- secondaryStable-but-static management: Company is 15 years old and no new directors in the last 3 years — succession not yet being planned internally.
