Is Clover a listed company?

I'm curious to know, is Clover a publicly traded company on any major stock exchange? Could you elaborate on the financial status and ownership structure of Clover, if it is indeed listed? And if not, what are the reasons behind the decision to remain private? Is there any potential for an IPO in the future? Additionally, could you discuss the implications of being a listed or unlisted company in terms of access to capital, regulation, and market valuation?
