Following in Antero’s footsteps, Rice Energy announced last week that they will launch an initial public offering (IPO) for stock in a new spun-off midstream subsidiary–Rice Midstream. You may recall Antero Resources, a company that concentrates on the Marcellus/Utica region, launched an IPO for their company a year ago that hauled in $1.57 billion (see Antero’s IPO Fetches $1.57B, Company Valued at $11B!). The much smaller Rice followed with their own IPO which did better than hoped, bringing in a cool $924 million (see Rice Energy IPO Soars, Brings in $84M More Than Expected). Antero very recently floated an IPO for a midstream subsidiary and hauled in another $1B (see Antero Midstream IPO Hauls in $1B, Stock Trading High). Now Rice is floating an IPO for a midstream subsidiary. No, not to keep up with the Jones (we don’t think, anyway). But because it makes sense. How much is Rice looking to make?…
