StealthGas, the US-listed LPG player, is to spin-off its tanker assets into a separate company that it plans to list on the Nasdaq stock exchange.

Imperial Petroleum will be the newly formed subsidiary that will act as the holding company for the four tanker vessels, the shipowner said in a regulatory filing.

The four vessels comprise the 115,000-dwt Stealth Berana (built 2010), the 47,000-dwt Clean Thrasher and Magic Wand (both built 2008), and the 46,000-dwt Falcon Maryam (built 2009).
