Recent Announcements

Steve Gray, Chief Executive Officer, commented, “We’re pleased to report another strong quarter highlighted by our sequential double digit production growth and record low cash operating costs per barrel. Our recent horizontal wells appear to confirm the effectiveness of our enhanced completion designs. The excellent well results across our asset base along with our current record production led us to raise our annual production guidance for the second consecutive quarter. As a result of the increased rate of return on our capital, we began accelerating our drilling and completion pace during the third quarter with the addition of a third operated horizontal rig. We expect to add a fourth rig in early 2017.” Mr. Gray added, “We are on track to close the first stage of our recently announced acquisition of Silver Hill later this month. We have been working closely with the Silver Hill team to ensure a smooth transition and to make preparations for enhanced infrastructure to accommodate a more robust horizontal development program on our newly acquired Delaware position.”

Use of Non-GAAP Financial Measures

We define Adjusted EBITDAX as oil and gas revenues including net cash receipts (payments) on settled derivative instruments and premiums paid on put options that settled during the period, less lease operating expenses, production and ad valorem taxes, and general and administrative expenses excluding stock based compensation. Adjusted Net Income deducts from Adjusted EBITDAX depreciation, depletion, and amortization, accretion on asset retirement obligations, exploration expenses, interest expense, stock-based compensation and adjusted income tax expense.

Management believes Adjusted EBITDAX and Adjusted Net Income are useful because they allow us to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to our financing methods or capital structure. We exclude the items listed above in arriving at Adjusted EBITDAX and Adjusted Net Income because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDAX and Adjusted Net Income should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP or as an indicator of our operating performance or liquidity. Certain items excluded from Adjusted EBITDAX and Adjusted Net Income are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic costs of depreciable assets, none of which are components of Adjusted EBITDAX. Our computations of Adjusted EBITDAX and Adjusted Net Income may not be comparable to other similarly titled measures of other companies.

The following tables include a reconciliation of the non-GAAP financial measures of Adjusted EBITDAX and Adjusted Net Income to the GAAP financial measure of net income.
