What this business does
Primary activity: Manufacture of metal structures and parts of structures
Sector: Manufacturing
Investor take
PursueStrong opportunity: active trading company with strong profile and bankable structure.
Opportunity 79/100 (strong), bankability 80/100. High owner-dependency — earn-out structure likely required for clean transition. Share purchase looks the cleaner deal structure. Biggest value-creation lever: Discharge stale live charges. 1 live charge(s) created 15+ years ago — likely paid but undischarged. Clean register. Most likely exit: share sale to pe / searcher (65/100).
🏦
Refinance opportunity
1 live charge · oldest 32.7y
65/100
clean up first
Refinance viable after a tidy-up — address the highlighted items first.
- · Oldest live charge is 32.7 years old — likely at or near maturity.
- · Single lender — cleanest path to refinance.
- · Legal-friction score 25/100 — 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
89/100
Critical — business is the founderThe business appears inseparable from the founder. Acquisition without a serious earn-out or meaningful transition period would likely destroy value.
FACTORS
- +Two-director setup: Only two active directors — typical of owner-managed SMEs but limits succession.
- +Founder name in company name: Company name contains director surname "PORTER" — strong identity link between founder and business.
- +Senior director age: Director aged approximately 59 — approaching natural succession window.
- +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.
Succession & seller-readiness
56/100
Strong succession signalMultiple signals suggest succession is on the horizon. Candidate for proactive outreach.
SIGNALS
- secondaryFounder aged 58+: Senior director is approximately 59. Early succession window.
- secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
- secondaryStable-but-static management: Company is 49 years old and no new directors in the last 3 years — succession not yet being planned internally.
