Investment thesis
Property vehicle with leveraged stack — refinance / partial-release angle.
Why interesting: Asset-backed; value largely in underlying property; lender engagement likely possible.
Why risky: Multiple lenders to manage; inter-creditor friction and partial-release cost possible.
Opportunity decay

Investor take
PursueStrong opportunity: active trading company with strong profile and acceptable with review structure.
Opportunity 79/100 (strong), bankability 57/100. High owner-dependency — earn-out structure likely required for clean transition. 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).

4 live charges · 2 lenders · oldest 5.6y
50/100
clean up first
Refinance viable after a tidy-up — address the highlighted items first.
- · Oldest live charge is 5.6 years old — likely at or near maturity.
- · Two lenders — manageable, but coordination required.
- · Legal-friction score 25/100 — workable, but lender will want more DD.

Owner dependency
71/100
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 64 — approaching natural succession window.
- +No director turnover: Company is 7 years old with no director changes — suggests a very tight-knit founder team never broadened.
Succession & seller-readiness
56/100
Strong succession signalMultiple signals suggest succession is on the horizon. Candidate for proactive outreach.
SIGNALS
- primaryFounder aged 63+: Senior director is approximately 64. Approaching typical UK retirement age — succession thinking likely.
- secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
