SandRidge Energy, Inc. (“SandRidge” or the “Company”) has retained Tristone Capital (“Tristone”) and Deutsche Bank Securities (“Deutsche Bank”) to provide transaction advisory services and technical support for the sale of its East Texas and North Louisiana oil and gas assets (“Properties”). The Properties are being offered in two separate packages: East Texas and North Louisiana. The East Texas Package is further being offered by Sub-Package: Cotton Valley and Bossier / Haynesville Shale.

This transaction represents an exit from the region for SandRidge and, as such, infrastructure assets will be included and operating personnel will be made available.
