Investment thesis
Zombie company — trading but stalled; unlikely mover.
Why interesting: Quiet, steady; could be a succession or carve-out candidate with the right conversation.
Why risky: No growth signal; thin margin for error on price.

What this business does
Primary activity: SIC 33160
Sector: Manufacturing
Investor take
Pass (distressed without resilience)
Distressed active trading company — structural issues outweigh the discount.

Opportunity 63/100 (worth a look), bankability 65/100. High owner-dependency — earn-out structure likely required for clean transition. Biggest value-creation lever: Resolve: Confirmation statement overdue. Annual confirmation statement not filed on time. Required statutory filing — overdue is a strong discipline signal. Most likely exit: share sale to pe / searcher (58/100).

Data confidence

Overall: medium (73/100)

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

Owner dependency

80/100
Critical — business is the founder

The business appears inseparable from the founder. Acquisition without a serious earn-out or meaningful transition period would likely destroy value.

FACTORS
  • +Sole director: Only one active director — all governance concentrated on one person.
  • +No director turnover: Company is 5 years old with no director changes — suggests a very tight-knit founder team never broadened.

Succession & seller-readiness

45/100
Moderate signal

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

SIGNALS
  • primarySole active director: Only one director in control. No visible successor — buyers solve the succession problem.

Red flags

1 high ·
Confirmation statement overdue
high

Annual confirmation statement not filed on time. Required statutory filing — overdue is a strong discipline signal.
