The company also estimated its fully diluted net asset value (NAV) at $11.73 per share. C3is cautioned that the figure is a snapshot in time and relies on assumptions and estimates.

The company has a fleet of six vessels. These include three Handysize dry bulk carriers, one Aframax tanker and two product tankers.
