Investor take
Pursue
Asset-holding vehicle with a 68-year-old founder — textbook succession opportunity.

Opportunity 79/100 (strong), bankability 75/100. Strong seller-intent signal (63/100, director aged 68). Share purchase looks the cleaner deal structure. Biggest value-creation lever: Cash flow review and working-capital discipline. Cash down -93% YoY — forensic review of receivables, stock turns, and creditor days. Most likely exit: share sale to pe / searcher (65/100).
