What this business does
Primary activity: SIC 09100
Sector: Mining & quarrying
Investor take
PursueActive trading company with a 62-year-old founder — textbook succession opportunity.
Opportunity 78/100 (strong), bankability 77/100. Strong seller-intent signal (65/100, director aged 62). Share purchase looks the cleaner deal structure. Biggest value-creation lever: Consolidate lender relationships. 3 distinct lenders creates friction — refinance into single-lender structure for cleaner diligence. Most likely exit: share sale to pe / searcher (73/100).
🏦
Refinance opportunity
3 live charges · 3 lenders · oldest 40.1y
35/100
too messy
Refinance path is blocked by complexity. Rethink structure or expect bespoke, expensive terms.
- · Oldest live charge is 40.1 years old — likely at or near maturity.
- · 3 lenders named — inter-creditor friction likely.
- · Legal-friction score 30/100 — workable, but lender will want more DD.
Data confidence
Overall: medium (79/100)Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.

Owner dependency
66/100
High — earn-out structure requiredMaterial founder dependency. Consider a 2-3 year earn-out and build in a handover plan before completion.
FACTORS
- +Two-director setup: Only two active directors — typical of owner-managed SMEs but limits succession.
- +Senior director age: Director aged approximately 62 — approaching natural succession window.
Succession & seller-readiness
61/100
Strong succession signalMultiple signals suggest succession is on the horizon. Candidate for proactive outreach.
SIGNALS
- secondaryFounder aged 58+: Senior director is approximately 62. Early succession window.
- secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
- secondaryStable-but-static management: Company is 41 years old and no new directors in the last 3 years — succession not yet being planned internally.
- supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
