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: Engineering related scientific and technical consulting activities
Sector: Professional, scientific & technical
Investor take
Pursue
Strong opportunity: asset-holding vehicle with strong profile and bankable structure.

Opportunity 72/100 (strong), bankability 75/100. 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: medium (78/100)

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