Investment thesis
Zombie company — trading but stalled; unlikely mover.
Why interesting: Quiet, steady; could be a succession or carve-out candidate with the right conversation.
Why risky: No growth signal; thin margin for error on price.
Why now
Window steady · low confidence
Steady and stalled — no momentum either way. Needs an approach trigger.

What this business does
Primary activity: Other construction installation
Sector: Construction
Investor take
Pass (distressed without resilience)
Distressed active trading company — structural issues outweigh the discount.

Opportunity 72/100 (strong), bankability 75/100. High owner-dependency — earn-out structure likely required for clean transition. Share purchase looks the cleaner deal structure. Biggest value-creation lever: Broaden director team. Sole director creates succession risk and reduces buyer comfort. Appoint a second director or strong #2. Most likely exit: distressed disposal / insolvency (65/100).

Data confidence

Overall: high (80/100)
