Primary activity: SIC 43130
Sector: Construction
Investor take
PursueAsset-holding vehicle with a 65-year-old founder — textbook succession opportunity.
Opportunity 78/100 (strong), bankability 75/100. Strong seller-intent signal (68/100, director aged 65). Share purchase looks the cleaner deal structure. Biggest value-creation lever: Broaden director team. Sole director creates succession risk and reduces buyer comfort. Appoint a second director or strong #2. Most likely exit: share sale to pe / searcher (73/100).
Data confidence
Overall: medium (76/100)Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.

Owner dependency
100/100

FACTORS
- +Sole director: Only one active director — all governance concentrated on one person.
- +Founder name in company name: Company name contains director surname "BONNAR" — strong identity link between founder and business.
- +Founder age: Director aged approximately 65 — succession pressure is live.
