CALGARY, AB, Feb. 21, 2024 /CNW/ - Enerplus Corporation ("Enerplus" or the "Company") (TSX: ERF) (NYSE: ERF) today reported fourth quarter 2023 cash flow from operating activities and adjusted funds flow(1) of $297.9 million and $240.5 million, respectively, compared to $316.6 million and $315.4 million, respectively, in the fourth quarter of 2022. Full year 2023 cash flow from operating activities and adjusted funds flow(1) was $938.2 million and $961.2 million, respectively, compared to $1,173.4 million and $1,230.3 million, in 2022.

On February 21, 2024, Enerplus entered into an arrangement agreement with Chord Energy Corporation ("Chord"), pursuant to which, upon completion of the transaction, Enerplus shareholders will receive 0.10125 shares of Chord common stock and $1.84 in cash for each share of Enerplus (90% stock and 10% cash consideration). The transaction is subject to various approvals and conditions to close and is expected to be completed mid-2024. For more information refer to the joint press release of Enerplus and Chord regarding this transaction.

HIGHLIGHTS - FULL YEAR 2023

"2023 marked another year of solid operational and financial performance, further demonstrating the quality of our team and North Dakota Bakken position," said Ian C. Dundas, President and CEO. "We exceeded production targets within a disciplined capital allocation framework, helping to drive free cash flow of over $400 million. Consistent with our track record, we returned significant cash to shareholders - over 70% of free cash flow in 2023 - through dividends and share repurchases, while also reducing net debt by 46%."

FOURTH QUARTER 2023 SUMMARY

Total production for the fourth quarter of 2023 was 103,543 BOE per day, a decrease of 3% compared to the same period in 2022. Liquids production in the fourth quarter was 67,097 barrels per day, an increase of 3% compared to the same period in 2022. Strong well performance in North Dakota supported fourth quarter 2023 liquids production, while lower activity levels in the Marcellus throughout 2023 and the impact from the sale of Canadian assets during the fourth quarter of 2022 led to the decrease in total production year-over-year. The Company's fourth quarter production exceeded the top end of the total and liquids production guidance ranges of 95,000 to 99,000 BOE per day and 60,500 to 64,500 barrels per day, respectively.

In North Dakota, Enerplus drilled 19 operated wells (79% average working interest) during the quarter, with no operated wells brought on production. North Dakota production averaged 78,222 BOE per day in the quarter. Marcellus production averaged 143 MMcf per day in the quarter.

Enerplus reported fourth quarter 2023 net income of $116.7 million, or $0.57 per share (basic), compared to net income of $330.7 million, or $1.49 per share (basic), in the fourth quarter of 2022. Excluding certain non-cash or non-recurring items, fourth quarter 2023 adjusted net income(1) was $115.3 million, or $0.56 per share (basic), compared to $181.1 million, or $0.81 per share (basic), during the same period in 2022. The reduction in net income was due to the gain on the sale of the Canadian assets recorded during the fourth quarter of 2022, as well as lower production and commodity prices, which also decreased adjusted net income, relative to the prior year period.

Enerplus' realized fourth quarter 2023 Bakken crude oil price differential was $1.26 per barrel below WTI, compared to $1.05 per barrel above WTI for the same period in 2022. Bakken crude oil prices were weaker than the prior year period due to elevated local production growth driven predominantly by an acceleration in well completion activity resulting in less spare pipeline capacity in 2023, while refinery demand deteriorated in the fourth quarter of 2023 due to a decline in global refinery margins. Enerplus' fourth quarter 2023 Marcellus natural gas price differential was $1.20 per Mcf below NYMEX, compared to $1.18 per Mcf below NYMEX for the same period in 2022.

Operating expenses in the fourth quarter of 2023 were $11.67 per BOE, compared to $9.68 per BOE in the same period in 2022. The increase in per unit operating expenses was primarily due to inflation adjusted contract pricing and higher gas facility and fluid handling charges due to the increase in North Dakota production. Cash general and administrative ("G&A") expenses were $1.41 per BOE in the fourth quarter of 2023, compared to $1.15 per BOE in the prior year period due to inflationary pressures on labour and services.

Capital spending totaled $91.5 million in the fourth quarter. The Company paid $12.2 million in dividends during the quarter and repurchased 5.8 million shares at an average price of $16.09 per share for a total cost of $93.8 million.

Current tax expense was $0.2 million in the fourth quarter.

Enerplus ended the fourth quarter with net debt(1) of $119.3 million and had a net debt to adjusted funds flow ratio(1) of 0.1 times.

FULL YEAR 2023 SUMMARY

Total production for 2023 was 100,015 BOE per day, broadly flat compared to 2022. Liquids production in 2023 was 62,208, an increase of 1% compared to 2022. Liquids production increased by 9% year-over-year when adjusted for the Canadian asset divestments completed in 2022. The Company's 2023 production exceeded the top end of the total and liquids production guidance ranges of 98,000 to 99,000 BOE per day and 60,500 to 61,500 barrels per day, respectively.

Enerplus reported full year 2023 net income of $456.1 million, or $2.16 per share (basic), compared to net income of $914.3 million, or $3.91 per share (basic), in 2022. Excluding certain non-cash or non-recurring items, 2023 adjusted net income(1) was $477.6 million, or $2.26 per share (basic), compared to $707.1 million, or $3.02 per share (basic), in 2022. The lower net income in 2023 was due to the gain on the sale of the Canadian assets recorded during 2022, as well as lower production and commodity prices, which also decreased adjusted net income, relative to the prior year period.

Enerplus' 2023 realized Bakken crude oil price differential was $0.45 per barrel below WTI, compared to $1.09 per barrel above WTI in 2022. Bakken differentials weakened through the second half of 2023 due to local production growth driven by an acceleration in well completion activity resulting in less spare pipeline capacity in 2023, while refinery demand deteriorated in the fourth quarter of 2023 due to a decline in global refinery margins. Enerplus' 2023 Marcellus natural gas price differential was $0.92 per Mcf below NYMEX, compared to $0.72 per Mcf below NYMEX in 2022.

Operating expenses in 2023 were $10.67 per BOE, compared to $9.99 per BOE in 2022. The increase in per BOE operating expenses was primarily due to inflation adjusted contract pricing and higher gas facility and fluid handling charges as a result of increased production in North Dakota. Cash G&A expenses in 2023 were $1.33 per BOE, compared to $1.17 per BOE in 2022 due to inflationary pressures on labour and services.

Current tax expense was $27.2 million in 2023.

Capital spending totaled $532.5 million in 2023, approximately the midpoint of the Company's guidance range of $520 to $540 million. The Company paid $48.6 million in dividends in 2023 and repurchased 16.4 million shares at an average price of $15.71 per share for a total of $258.3 million. In total, Enerplus returned $306.9 million to shareholders in 2023.

ENVIRONMENTAL, SOCIAL AND GOVERNANCE (ESG) UPDATE

Enerplus continues to make progress on its ESG initiatives in 2023. Based on preliminary estimates and relative to its 2021 baseline, the Company reduced 2023 methane emissions intensity by 45% and Scope 1 and Scope 2 GHG emissions intensity by 40%.

The Company continues to work towards its longer-term emissions reduction targets, including a methane emissions intensity of 0.02 kg CH4/BOE by 2030, and a Scope 1 and Scope 2 GHG emissions intensity of 13 kg CO2e/BOE by 2030, which equates to an approximate intensity reduction of 45% and 30%, respectively, from Enerplus' preliminary 2023 estimates.

As previously disclosed, as part of its emissions reduction strategy Enerplus is endorsing the World Bank Zero Routine Flaring by 2030 initiative and has established a flare intensity target of less than 2% per thousand cubic feet of natural gas produced by 2026.

2024 OUTLOOK

As previously announced, Enerplus expects 2024 capital spending of approximately $550 million and annual average liquids production of approximately 64,000 barrels per day.  The Company expects 2024 annual average total production of approximately 99,000 BOE per day(1). The Company's 2024 outlook is subject to changes as a result of completion of the transaction with Chord, which is currently expected to close mid-2024.

On February 21, 2024, the Board approved a dividend increase of 8% to the quarterly dividend to $0.065 per share beginning with the March 15, 2024 dividend. It is anticipated that the quarterly dividend payments made by Enerplus until closing of the transaction will be equalized to those made by Chord, after giving effect to the exchange ratio, through an additional Enerplus dividend declared shortly prior to the closing.

NOTICE REGARDING INFORMATION CONTAINED IN THIS NEWS RELEASE

Currency and Accounting Principles

All amounts in this news release are stated in U.S. dollars unless otherwise specified. All financial information in this news release has been prepared and presented in accordance with U.S. GAAP, except as noted below under "Non-GAAP and Other Financial Measures".

Barrels of Oil Equivalent

This news release contains references to "BOE" (barrels of oil equivalent), "MBOE" (one thousand barrels of oil equivalent), and "MMBOE" (one million barrels of oil equivalent). Enerplus has adopted the standard of six thousand cubic feet of gas to one barrel of oil (6 Mcf: 1 bbl) when converting natural gas to BOEs.  BOE, MBOE and MMBOE may be misleading, particularly if used in isolation.  The foregoing conversion ratios are based on an energy equivalency conversion method primarily applicable at the burner tip and do not represent a value equivalency at the wellhead. Given that the value ratio based on the current price of oil as compared to natural gas is significantly different from the energy equivalent of 6:1, utilizing a conversion on a 6:1 basis may be misleading.

Presentation of Production and Reserves Information

All production volumes presented in this news release are reported on a "net" basis (the Company's working interest share after deduction of royalty obligations, plus the Company's royalty interests), unless expressly indicated that it is being presented on a "gross" basis.

NON-GAAP AND OTHER FINANCIAL MEASURES 

Non-GAAP Financial Measures

This news release includes references to certain non-GAAP financial measures and non-GAAP ratios used by the Company to evaluate its financial performance, financial position or cash flow. Non-GAAP financial measures are financial measures disclosed by a company that (a) depict historical or expected future financial performance, financial position or cash flow of a company, (b) with respect to their composition, exclude amounts that are included in, or include amounts that are excluded from, the composition of the most directly comparable financial measure disclosed in the primary financial statements of the company, (c) are not disclosed in the financial statements of the company and (d) are not a ratio, fraction, percentage or similar representation. Non-GAAP ratios are financial measures disclosed by a company that are in the form of a ratio, fraction, percentage or similar representation that has a non-GAAP financial measure as one or more of its components, and that are not disclosed in the financial statements of the company.

These non-GAAP financial measures and non-GAAP ratios do not have standardized meanings or definitions as prescribed by U.S. GAAP and may not be comparable with the calculation of similar financial measures by other entities. For each measure, we have: (a) indicated the composition of the measure; (b) identified the most directly comparable GAAP financial measure and provided comparative detail where appropriate; (c) indicated the reconciliation of the measure to the most directly comparable GAAP financial measure to the extent one exists; and (d) provided details on the usefulness of the measure for the reader. These non-GAAP financial measures and non-GAAP ratios should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.

"Adjusted funds flow" is used by Enerplus and is useful to investors and securities analysts in analyzing Enerplus' ability to generate funds to repay debt, pay dividends, and fund future capital investment. The most directly comparable GAAP measure is cash flow from operating activities. Adjusted funds flow is calculated as cash flow from operating activities before asset retirement obligation expenditures and changes in non-cash operating working capital.

"Adjusted funds flow before tax" is used by Enerplus and is useful to investors and securities analysts in analyzing Enerplus' current income tax expense as a percentage of adjusted funds flow before tax. The most directly comparable GAAP measure is cash flow from operating activities. Adjusted funds flow before tax is calculated as adjusted funds flow plus current income tax expense.

"Adjusted net income/(loss)" is used by Enerplus and is useful to investors and securities analysts in evaluating the financial performance of the company by adjusting for certain unrealized items and other items that the company considers appropriate to adjust given their irregular nature. The most directly comparable GAAP measure is net income/(loss).

"Free cash flow" is used by Enerplus and is useful to investors and securities analysts in analyzing operating and financial performance, leverage and liquidity. Free cash flow is calculated as adjusted funds flow minus capital spending. The most directly comparable GAAP measure is cash flow from operating activities.

"Net debt" is used by Enerplus and is useful to investors and securities analysts in analyzing overall leverage and financial position at the end of the period. Net debt is calculated as current and long-term debt associated with senior notes plus any outstanding Bank Credit Facilities balances, less cash and cash equivalents. There is no directly comparable GAAP equivalent.

"Net debt to adjusted funds flow ratio" is used by Enerplus and is useful to investors and securities analysts in analyzing leverage and liquidity. The net debt to adjusted funds flow ratio is calculated as net debt divided by a trailing twelve months of adjusted funds flow. There is no directly comparable GAAP equivalent for this measure, and it is not equivalent to any of our debt covenants.

Other Financial Measures

SUPPLEMENTARY FINANCIAL MEASURES

Supplementary financial measures are financial measures disclosed by a company that (a) are, or are intended to be, disclosed on a periodic basis to depict the historical or expected future financial performance, financial position or cash flow of a company, (b) are not disclosed in the financial statements of the company, (c) are not non-GAAP financial measures, and (d) are not non-GAAP ratios. The following section provides an explanation of the composition of those supplementary financial measures if not previously provided:

"Capital spending" Capital and office expenditures, excluding other capital assets/office capital and property and land acquisitions and divestments and non-cash investing working capital.

"Cash general and administrative expenses" or "Cash G&A expenses" General and administrative expenses that are settled through cash payout, as opposed to expenses that relate to accretion or other non-cash allocations that are recorded as part of general and administrative expenses.

"Cash share-based compensation" or "Cash SBC expenses" Share-based compensation that is settled by way of cash payout, as opposed to equity settled.
