What this business does
Primary activity: Research and experimental development on biotechnology
Sector: Professional, scientific & technical
Investor take
Pass (distressed without resilience)
Distressed unclear — structural issues outweigh the discount.

Opportunity 61/100 (worth a look), bankability 70/100. Strong seller-intent signal (63/100, director aged 65). Share purchase looks the cleaner deal structure. Biggest value-creation lever: Resolve: Company dissolved. Company has been dissolved — it no longer legally exists. Any diligence here is historical only. Most likely exit: share sale to pe / searcher (65/100).

Data confidence

Overall: medium (56/100)

Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.

Owner dependency

73/100
High — earn-out structure required

Material founder dependency. Consider a 2-3 year earn-out and build in a handover plan before completion.

FACTORS
  • +Two-director setup: Only two active directors — typical of owner-managed SMEs but limits succession.
  • +Founder age: Director aged approximately 65 — succession pressure is live.

Succession & seller-readiness

69/100
Strong succession signal

Multiple signals suggest succession is on the horizon. Candidate for proactive outreach.

SIGNALS
  • primaryFounder aged 63+: Senior director is approximately 65. Approaching typical UK retirement age — succession thinking likely.
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
  • secondary12+ year tenure: Director in role 15 years.
  • supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
