Investor take
PursueActive trading company with a 63-year-old founder — textbook succession opportunity.
Opportunity 77/100 (strong), bankability 77/100. Strong seller-intent signal (60/100, director aged 63). 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 (65/100).
🏦
Refinance opportunity
4 live charges · 3 lenders · oldest 18.4y
35/100
too messy
Refinance path is blocked by complexity. Rethink structure or expect bespoke, expensive terms.
- · Oldest live charge is 18.4 years old — likely at or near maturity.
- · 3 lenders named — inter-creditor friction likely.
- · Legal-friction score 33/100 — workable, but lender will want more DD.
