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.

Why now

Window steady · high confidence

Thesis has shifted recently — watch for confirmation.

· Lifecycle stage: early → zombie
· Investment thesis: growth_story → zombie_hold
· Deal-killer verdict: clean → workable
· Hygiene score: 90 → 85

Opportunity decay

drifting distress · 6-months

Drifting toward distress — expect more negotiability in 3–6 months, but also more friction.

· Lifecycle stage drifting downward
· Currently "zombie"

What this business does

Primary activity: Engineering related scientific and technical consulting activities

Sector: Professional, scientific & technical

Investor take

Pursue

Strong opportunity: active trading company with strong profile and acceptable with review structure.

Opportunity 71/100 (strong), bankability 70/100. High owner-dependency — earn-out structure likely required for clean transition. Share purchase looks the cleaner deal structure. Biggest value-creation lever: Broaden director team. Sole director creates succession risk and reduces buyer comfort. Appoint a second director or strong #2. Most likely exit: share sale to pe / searcher (58/100).

Data confidence

Overall: high (85/100)

Strong data coverage across all sections. AI outputs should be trusted with minimal caveats.
