According to that PR that Circadian put out, they never ruled out the entire Circadian network of companies as a whole not going public, only that specific company as an individual entity. Or is this just wishful thinking.
"It has come to our attention that one of our entities, Circadian, Inc., a privately owned, recently incorporated Delaware corporation, has been misrepresented on several investment websites as being traded under the symbol CKDN.PK. As a privately owned company, Circadian, Inc. is not being traded and is not in anyway associated with a long defunct Californian corporation which used the name Circadian, Inc.
Circadian, Inc. is part of the network of Circadian companies (www.circadian.com), each of which is a separate and independent legal entity. Circadian, Inc.(by itself) is not traded publicly nor does the company have any intention of being a publicly traded company in the near future."
