The New York Stock Exchange (NYSE) has moved forward with proceedings to delist Atlas Energy Group LLC (ATLS). NYSE also suspended trading of the company's common units on Friday. The move comes nearly three months after NYSE first notified the company that its market capitalization and stockholder equity had fallen below the $50 million minimum over a consecutive 30-day trading period (see Shale DailyDec. 31, 2015). While Atlas said it is "considering what actions, if any, it may take in response to the decision," its units started trading on the over-the-counter market OTCQX on Monday. ATLS owns all of the general partner interest, distribution rights and a 23% limited partner interest in upstream subsidiary Atlas Resource Partners LP (ARP). ARP, a separately traded company with producing wells and reserves in 17 states that include assets in the Barnett, Eagle Ford, Marcellus and Utica shales, is not affected by the ATLS delisting. ARP's stock, which is traded on the NYSE, has performed poorly, however, with a 52-week low of 56 cents/share.
