Investor take
Special-situation opportunityDistressed trade-services with salvageable qualities — special-situations priority.
Opportunity 67/100 (strong), bankability 65/100. High owner-dependency — earn-out structure likely required for clean transition. Share purchase looks the cleaner deal structure. 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 (76/100)Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.

Owner dependency
85/100
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
- +Sole director: Only one active director — all governance concentrated on one person.
- +Long-tenure founder: Senior director has been in place 17 years — deep operational knowledge concentrated in one person.
Succession & seller-readiness
63/100
Strong succession signalMultiple signals suggest succession is on the horizon. Candidate for proactive outreach.
SIGNALS
- primarySole active director: Only one director in control. No visible successor — buyers solve the succession problem.
- secondary12+ year tenure: Director in role 17 years.
- secondaryStable-but-static management: Company is 17 years old and no new directors in the last 3 years — succession not yet being planned internally.
