(1) All metrics have been calculated based on the best available information and consistent with required reporting, where applicable. Greenhouse Gas Emissions are based on Earthstone’s gross operated operations and metrics are calculated in accordance with the standards of the Environmental Protection Agency (“EPA”).

(2) Peers include CDEV, CPE, FANG, LPI, MTDR, PXD and SM. Data compiled from company published data for most recent available year (2020 or 2021) and from publicly available EPA reports as of June 30, 2022.

(3) Gross natural gas flared / gross natural gas produced.
