Disadvantages to watch
- Capital intensity: Manufacturing equipment ties up capital in factories and inventory, raising risk if demand slows.
- Thin margins: Profit margins are only ~8%, so cost spikes could erode earnings.
- GMP: The grey market premium is nil, indicating cautious sentiment.
- Tech risk: Rapid innovation means Prostarm Info Systems must keep upgrading to stay relevant.
Bottomline
In short, the Prostarm Info Systems IPO offers exposure to a growing power-backup equipment maker, but its thin profit margins and capital-intensive model mean significant risks.
