Alta Mesa Resources, Inc. /DE

Silver Run Acquisition Corporation II, trading under the ticker SRUN on the Nasdaq, was a blank check company sponsored by Riverstone Holdings, the energy-focused private equity firm. The SPAC completed its initial public offering in 2017, targeting acquisition opportunities in the oil and gas sector. The August 2017 10-Q filing reflected the company's pre-combination status as it searched for a suitable upstream energy target. Silver Run II ultimately agreed to combine with Alta Mesa Holdings and Kingfisher Midstream, gaining exposure to the STACK play in Oklahoma, with that transaction closing in early 2019.
