What this business does
Primary activity: SIC 03210
Sector: Agriculture, forestry & fishing
Investor take
Special-situation opportunity
Distressed agriculture with salvageable qualities — special-situations priority.

Opportunity 61/100 (worth a look), bankability 55/100. 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 (38/100).
