What this business does
Primary activity: Technical testing and analysis
Sector: Professional, scientific & technical
Investor take
Special-situation opportunity
Distressed professional-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: Cash flow review and working-capital discipline. Cash down -45% YoY — forensic review of receivables, stock turns, and creditor days. Most likely exit: share sale to pe / searcher (58/100).

    director

Owner dependency

90/100
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.
  • +Long-tenure founder: Senior director has been in place 17 years — deep operational knowledge concentrated in one person.
  • +No director turnover: Company is 17 years old with no director changes — suggests a very tight-knit founder team never broadened.

Succession & seller-readiness

63/100
Strong succession signal

Multiple 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.

Red flags
