EP Energy, an Apollo-backed E&P of oil, natural gas and NGL in the US, filed on Wednesday with the SEC to raise up to $100 million in an initial public offering, although the deal size is likely a placeholder. We estimate the deal will raise at least $500 million. The Houston, TX-based company, which was founded in 2012 and booked $1.7 billion in sales for the 12 months ended June 30, 2013, plans to list on the NYSE under the symbol EPE. The bookrunners on the deal were not announced in the initial filing. No pricing terms were disclosed.
