Investment thesis
Growth-phase business — story-led; valuation sensitive to momentum.
Why interesting: Trading is scaling; acquirers paying for trajectory get disproportionate leverage.
Why risky: Price often leads fundamentals; dependency on founder often high.

Investor take
Pass (distressed without resilience)
Distressed admin-neglect survivor — structural issues outweigh the discount.

Opportunity 57/100 (worth a look), bankability 40/100. High owner-dependency — earn-out structure likely required for clean transition. Share purchase looks the cleaner deal structure. Biggest value-creation lever: File overdue accounts. Clears statutory overdue flag — immediate bankability uplift for refinance conversations. Most likely exit: share sale to pe / searcher (53/100). Current lenders should be on monthly review.

Data confidence

Overall: medium (69/100)

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