What this business does

Primary activity: Plumbing, heat and air-conditioning installation

Sector: Construction

Investor take

Special-situation opportunity

Distressed construction with salvageable qualities — special-situations priority.

Opportunity 63/100 (worth a look), 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

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.
