What this business does
Primary activity: SIC 35110
Sector: Electricity, gas & energy
Investor take
PursueStrong opportunity: active trading company with strong profile and bankable structure.
Opportunity 74/100 (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: Cash flow review and working-capital discipline. Cash down -53% YoY — forensic review of receivables, stock turns, and creditor days. Most likely exit: strategic trade sale (63/100).
🏦
Refinance opportunity
2 live charges · 2 lenders · oldest 14.1y
30/100
under pressure
Refinance would be pressure-driven, not opportunity-driven. Expect tighter margins and covenant scrutiny.
- · Oldest live charge is 14.1 years old — likely at or near maturity.
- · Two lenders — manageable, but coordination required.
- · Cashflow trend is negative — lender view likely cautious.
Data confidence
Overall: high (84/100)Strong data coverage across all sections. AI outputs should be trusted with minimal caveats.
