Looking at the listing requirements, it seems a company only needs $5 million in assets. However, that seems pretty small. I think I'll let a more experienced member give the definitive answer.
There are multiple avenues to list, and multiple requirements in each. The most common routes are by minimum revenue over the past 3 years, which they'd have trouble with. But there's a route for a company with lots of assets, and equity. This requires 80 million total assets, and a market cap of 160 Million. See page 6 of the below guide, Standard 4:
If their first acquisition of 5+ ships (I think they may have raised it to 8 late in the summer) provides assets of 25+ million, and they do another 2 asset purchases of similar size in the next 6 months or so, and the market cap adjusts to reflect with even a 2X multiple on assets, they would meet standard 4 with ease, IMO.
