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.

50/100
Moderate — manageable with handover

Some founder dependency, but not acute. A structured handover period should cover most risk.

40/100
Moderate signal

Some succession indicators present. Worth watching; approach if sector/strategy fits.
