Whiting Petroleum Corporation (NYSE:WLL) ("Whiting" or the "Company") today announced fourth quarter 2021 results.

Fourth Quarter 2021 Highlights

Revenue was $473 million for the quarter ending December 31, 2021
Net income (GAAP) was $292 million or $7.34 per diluted share
Adjusted net income (non-GAAP) was $168 million or $4.23 per diluted share
Adjusted EBITDAX (non-GAAP) was $226 million
Net cash provided by operating activities (GAAP) was $214 million
Adjusted free cash flow (non-GAAP) was $156 million
December 31, 2021 debt was $0

Lynn A. Peterson, President and CEO commented, "2021 was an eventful year as the Company had many accomplishments that strengthen us for the future. The Company generated over $500 million of adjusted free cash flow, paid off over $360 million on its revolver, spent over $120 million for acquisitions net of divestitures, and ended the year completely debt free. We divested of non-core assets in Colorado and added meaningful drilling inventory through the Company's acquisition of working interest in its core Sanish field. The Company's year-end reserve volumes increased 25% over the previous year driven by the significant change in commodity pricing as well as additions from our drilling program and acquisitions. As of December 31, 2021, our proved developed properties alone were valued at $3.6 billion, pre-tax and using SEC pricing of $66.56 per barrel. We recently announced our first fixed dividend that is competitive to industry peers on a yield basis, with the expectation of growing our total return of capital significantly in the coming quarters through buybacks and other strategies. We continue to develop Whiting's strategies of value creation for the Company's stakeholders, provide a safe environment for our employees and contractors, and advance our ESG initiatives."

Fourth Quarter and Full Year 2021 Results

Revenue for the fourth quarter of 2021 increased $72 million to $473 million when compared to the third quarter of 2021, primarily due to increased commodity prices between periods. Revenue for the full year 2021 was $1.5 billion.

Net income for the fourth quarter of 2021 was $292 million, or $7.34 per share, as compared to $198 million, or $5.00 per share, for the third quarter of 2021. Net income for the twelve months ending December 31, 2021 was $428 million, or $10.78 per share. Adjusted net income (non-GAAP) for the fourth quarter of 2021 was $168 million, or $4.23 per diluted share, as compared to $142 million, or $3.57 per diluted share, for the third quarter of 2021. Adjusted net income (non-GAAP) for the twelve months ending December 31, 2021 was $535 million, or $13.49 per share. The primary difference between net income and adjusted net income for all periods is non-cash expense related to the change in the value of the Company's hedging portfolio. The third quarter was also affected by the gain on sale of properties related to a previously announced divestiture.

The Company's adjusted EBITDAX (non-GAAP) for the fourth quarter of 2021 was $226 million compared to $201 million for the third quarter of 2021. Net cash provided by operating activities was $214 million in the fourth quarter and adjusted free cash flow (non-GAAP) was $156 million. Adjusted EBITDAX (non-GAAP) for the twelve months ended December 31, 2021 was $774 million. Net cash provided by operating activities was $740 million and adjusted free cash flow (non-GAAP) was $504 million for the twelve months ended December 31, 2021.

Adjusted net income, adjusted net income per share, adjusted EBITDAX and adjusted free cash flow are non-GAAP financial measures. Please refer to the end of this release for disclosures and reconciliations regarding these measures.

Production for the fourth quarter averaged 92.8 thousand barrels of oil equivalent per day (MBOE/d) which was consistent with the previous quarter of 92.1 MBOE/d. Oil production averaged 52.9 thousand barrels of oil per day (MBO/d) compared to 51.8 MBO/d in the third quarter 2021.

Capital expenditures in the fourth quarter of 2021 were $66 million compared to the third quarter 2021 spend of $67 million. During the quarter, the Company drilled 17 gross/10.4 net operated wells and turned in line 16 gross/12.0 net operated wells. As of December 31, 2021, the Company has 34 gross (20.2 net) drilled uncompleted wells.

Lease operating expense (LOE) for the fourth quarter of 2021 was $62 million compared to $57 million in the third quarter of 2021. The increase was primarily due to more operated expense workovers and the effects of higher production. General and administrative expenses in the fourth quarter of 2021 were $15 million compared to $12 million in the third quarter 2021. Both quarters included approximately $3 million of non-cash stock compensation costs.

Liquidity

As of December 31, 2021, the Company had a borrowing base of $750 million on its revolving credit facility, no borrowings and unrestricted cash of $41 million, resulting in total liquidity of $790 million, net of outstanding letters of credit. Whiting expects to continue to fund its 2022 operations and its dividend fully within operating cash flow.

Proved Reserves

During 2021, the Company added 20.3 million barrels of oil equivalent (MMBOE) of reserves primarily due to successful drilling in the Williston Basin. Additionally, 15.9 MMBOE was added from acquisitions during the year, which was partially offset by a decrease of 10.7 MMBOE primarily due to the disposition of the Redtail field located in Colorado. As of December 31, 2021, the Company's estimated proved reserves totaled 326.0 MMBOE. The Standardized Measure of those reserves was $3,679 million and the pre-tax PV10% of those reserves was $4,381 million, in each case using SEC pricing as noted below.

The following table summarizes our estimated proved reserves as of December 31, 2021 with the corresponding pre-tax PV10% values:

Standardized measure of discounted future net cash flows

(1)		Oil and gas reserve quantities and related discounted future net cash flows have been derived from a WTI oil price of $66.56 per Bbl and a Henry Hub gas price of $3.60 per MMBtu, which were calculated using an average of the first-day-of-the-month price for each month within the 12 months ended December 31, 2021 as required by SEC and FASB guidelines.
(2)		Pre-tax PV10% may be considered a non-GAAP financial measure as defined by the SEC and is derived from the standardized measure of discounted future net cash flows (the "Standardized Measure"), which is the most directly comparable GAAP financial measure. Pre-tax PV10% is computed on the same basis as the Standardized Measure but without deducting future income taxes. We believe pre-tax PV10% is a useful measure for investors when evaluating the relative monetary significance of our oil and natural gas properties. We further believe investors may utilize our pre-tax PV10% as a basis for comparison of the relative size and value of our proved reserves to other companies because many factors that are unique to each individual company impact the amount of future income taxes to be paid. Our management uses this measure when assessing the potential return on investment related to our oil and gas properties and acquisitions. However, pre-tax PV10% is not a substitute for the Standardized Measure. Our pre-tax PV10% and Standardized Measure do not purport to present the fair value of our proved oil, NGL and natural gas reserves.

⁽¹⁾		Includes settlement periods of February through December 2022.
⁽²⁾		The weighted average price associated with the natural gas basis swaps shown in the table above represents the average fixed differential to NYMEX as stated in the related contracts, which is compared to the Northern Natural Gas Ventura Index ("NNG Ventura") for each period. If NYMEX combined with the fixed differential as stated in each contract is higher than the NNG Ventura index price at any settlement date, the Company receives the difference. Conversely, if the NNG Ventura index price is higher than NYMEX combined with the fixed differential, the Company pays the difference.

Adjusted net income and adjusted net income per share are non-GAAP measures. Management believes they provide useful information to investors for analysis of Whiting's fundamental business on a recurring basis. In addition, management believes that adjusted net income is widely used by professional research analysts and others in valuation, comparison and investment recommendations of companies in the oil and gas exploration and production industry, and many investors use the published research of industry research analysts in making investment decisions. Adjusted net income and adjusted net income per share should not be considered in isolation or as a substitute for net income, income from operations, net cash provided by operating activities or other income, cash flow or liquidity measures under U.S. GAAP and may not be comparable to other similarly titled measures of other companies.

⁽¹⁾

Adjusted free cash flow is a non-GAAP measure. This measure is presented because management believes it provides useful information to investors for analysis of the Company's ability to internally fund acquisitions and development activity and reduce its borrowings outstanding under its revolving credit facility. This measure should not be considered in isolation or as a substitute for net income, income from operations, net cash provided by operating activities or other income, cash flow or liquidity measures under U.S. GAAP and may not be comparable to other similarly titled measures of other companies. The Company is unable to present a reconciliation of forward-looking adjusted free cash flow because components of the calculation, including fluctuations in working capital accounts, are inherently unpredictable. Moreover, estimating the most directly comparable GAAP measure with the required precision necessary to provide a meaningful reconciliation is extremely difficult and could not be accomplished without unreasonable effort. The Company believes that forward-looking estimates of adjusted free cash flow are important to investors because they assist in the analysis of its ability to generate cash from our operations.
