Financial Results
For the second quarter 2020, Centennial reported net income of
Total equivalent production during the second quarter 2020 averaged 68,245 barrels of oil equivalent per day (“Boe/d”) compared to 76,122 Boe/d in the prior year period. Average daily crude oil production for the quarter was 37,411 barrels of oil per day (“Bbls/d”) compared to 43,105 Bbls/d in the prior year period.
“The second quarter was the most challenging crude oil price environment in recent history. To protect the balance sheet, Centennial drastically reduced capital expenditures. We also implemented a series of cost reduction initiatives that will continue to benefit the Company over time,” said
Second Quarter Operational Results
Centennial voluntarily curtailed approximately 20% of its May production volumes in response to weak realized prices. In order to minimize shut-in volumes, the Company continued to produce crude oil to on-site tank batteries, ultimately selling these stocks at materially higher prices later in the quarter. The majority of shut-in production volumes were brought-back online during June at essentially no incremental cost.
“We made the prudent decision to voluntarily shut-in a portion of our production during May. Notably, we experienced virtually no artificial lift failures or additional workover expenses associated with returning volumes to pre-shut-in levels,” Smith said.
Centennial has implemented numerous field-level projects targeting lower lease operating expenses (“LOE”), which have generated positive results. Second quarter LOE per Boe decreased 17% compared to the prior period, despite lower production volumes. Centennial recently completed the first phase of its electric substation in
“Our electrification project has reduced the number of generators in the field by 60%, resulting in lower equipment rental costs. Furthermore, we have significantly increased the usage of gas lift where feasible, lowering workover expenses,” Smith said. “Combined, these projects have lowered LOE costs, while reducing production downtime.”
As previously announced, Centennial took a series of actions during the quarter to lower cash general and administrative (“G&A”) expenses, including a reduction to its workforce, employee and executive management salaries,
Due to recent commodity price volatility, Centennial suspended all drilling and most completion activities in the second quarter. As a result, total capital expenditures incurred were
2020 Operational Plans and Targets
Centennial’s estimated fiscal year 2020 total capital budget is approximately
During the third quarter, Centennial commenced the completion of five wells that were drilled but uncompleted in
“As the price of crude oil has recovered from record lows, we are pleased to resume D&C activity on our asset base. Importantly, we expect our future drilling program to be underpinned by significantly lower well costs, as a result of higher efficiencies and structural cost improvements,” Smith said. “Year-to-date, our operations team has successfully reduced well costs by over 20% compared to last year, and we expect to deliver total well costs of approximately
“Based on our expected activity levels through year-end, we anticipate being cash flow neutral for the balance of the year, assuming strip pricing and inclusive of our oil hedges. This will enable us to prudently manage our liquidity while resuming activity,” Smith said.
The Company expects the current operational plan to deliver full year total equivalent production volumes of 64,000 Boe/d to 68,000 Boe/d, including crude oil volumes of 34,500 Bbls/d to 36,500 Bbls/d.

Cautionary Note Regarding Forward-Looking Statements
The information in this press release includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical fact included in this press release, regarding our strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. When used in this press release, the words “could,” “may,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project,” “goal”, “plan”, “target” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on management’s current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events.
Forward-looking statements may include statements about:
- volatility of oil, natural gas and NGL prices or a prolonged period of low oil, natural gas or NGL prices and the effects of actions by, or disputes among or between, members of the
Organization of Petroleum Exporting Countries (“OPEC”), such asSaudi Arabia , and other oil and natural gas producing countries, such asRussia , with respect to production levels or other matters related to the price of oil; - the effects of excess supply of oil and natural gas resulting from the reduced demand caused by the COVID-19 pandemic and the actions by certain oil and natural gas producing countries;
- our business strategy and future drilling plans;
- our reserves and our ability to replace the reserves we produce through drilling and property acquisitions;
- our drilling prospects, inventories, projects and programs;
- our financial strategy, liquidity and capital required for our development program;
- our realized oil, natural gas and NGL prices;
- the timing and amount of our future production of oil, natural gas and NGLs;
- our hedging strategy and results;
- our competition and government regulations;
- our ability to obtain permits and governmental approvals;
- our pending legal or environmental matters;
- the marketing and transportation of our oil, natural gas and NGLs;

- uncertainty regarding our future operating results;
- our plans, objectives, expectations and intentions contained in this press release that are not historical; and
- the other factors described in our Annual Report on Form 10-K for the year ended
December 31, 2019 , and any updates to those factors set forth in our subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K.
We caution you that these forward-looking statements are subject to all of the risks and uncertainties, most of which are difficult to predict and many of which are beyond our control, incident to the development, production, gathering and sale of oil and natural gas. These risks include, but are not limited to, commodity price volatility, inflation, lack of availability of drilling and production equipment and services, environmental risks, drilling and other operating risks, regulatory changes, the uncertainty inherent in estimating reserves and in projecting future rates of production, cash flow and access to capital, the timing of development expenditures and the other risks described in our filings with the
Reserve engineering is a process of estimating underground accumulations of oil and natural gas that cannot be measured in an exact way. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data and price and cost assumptions made by reserve engineers. In addition, the results of drilling, testing and production activities may justify revisions of estimates that were made previously. If significant, such revisions would change the schedule of any further production and development drilling. Accordingly, reserve estimates may differ significantly from the quantities of oil and natural gas that are ultimately recovered.
Should one or more of the risks or uncertainties described in this press release occur, or should underlying assumptions prove incorrect, our actual results and plans could differ materially from those expressed in any forward-looking statements. All forward-looking statements, expressed or implied, included in this press release are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that we or persons acting on our behalf may issue.
Except as otherwise required by applicable law, we disclaim any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this press release.

Non-GAAP Financial Measure
In addition to disclosing financial results calculated in accordance with
Adjusted EBITDAX
Adjusted EBITDAX is a supplemental non-GAAP financial measure that is used by management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. We define Adjusted EBITDAX as net income before interest expense, income taxes, depreciation, depletion and amortization, exploration costs, impairment and abandonment expenses, non-cash gains or losses on derivatives, stock-based compensation, gain on exchange of debt, gains and losses from the sale of assets, transaction costs and nonrecurring workforce reduction severance payments. Adjusted EBITDAX is not a measure of net income as determined by GAAP.
Our management believes Adjusted EBITDAX is useful as it allows them to more effectively evaluate our operating performance and compare the results of our operations from period to period and against our peers without regard to our financing methods or capital structure. We exclude the items listed above from net income in arriving at Adjusted EBITDAX 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 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 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 presentation of Adjusted EBITDAX should not be construed as an inference that our results will be unaffected by unusual or nonrecurring items. Our computations of Adjusted EBITDAX may not be comparable to other similarly titled measures of other companies.
The following table presents a reconciliation of Adjusted EBITDAX to net income, our most directly comparable financial measure calculated and presented in accordance with GAAP:

Net Debt / Book Capitalization Ratio
Net debt / book capitalization ratio is a supplemental non-GAAP financial measure that is used by management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. We define net debt / book capitalization ratio as net debt divided by book capitalization (non-GAAP). Net debt is defined as long-term debt, net, plus unamortized debt discount and issuance costs on Senior Notes minus cash and cash equivalents. Book capitalization (non-GAAP) is defined as long-term debt, net, plus unamortized debt discount and debt issuance costs on Senior Notes, plus total equity. Net debt / book capitalization ratio is not a measure calculated in accordance with GAAP.
Our management believes net debt / book capitalization ratio is useful as it allows them to more effectively evaluate our capital structure and liquidity and compare the results against our peers. Net debt / book capitalization ratio should not be considered as an alternative to, or more meaningful than, debt / book capitalization (GAAP) as determined in accordance with GAAP or as an indicator of our operating performance or liquidity.
