What this business does
Primary activity: Other research and experimental development on natural sciences and engineering
Sector: Professional, scientific & technical
Investor take
Pursue
Strong opportunity: active trading company with exceptional profile and bankable structure.

Opportunity 80/100 (exceptional), 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 19.3y

65/100
clean up first

Refinance viable after a tidy-up — address the highlighted items first.

  • · Oldest live charge is 19.3 years old — likely at or near maturity.
  • · Single lender — cleanest path to refinance.
  • · Legal-friction score 30/100 — workable, but lender will want more DD.

Data confidence

Overall: medium (60/100)

Some succession indicators present. Worth watching; approach if sector/strategy fits.

SIGNALS
  • secondaryFounder aged 58+: Senior director is approximately 62. Early succession window.
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
