CALGARY, AB, May 4, 2023 /CNW/ - Enerplus Corporation ("Enerplus" or the "Company") (TSX: ERF) (NYSE: ERF) today announced financial and operating results for the first quarter of 2023. The Company reported first quarter 2023 cash flow from operating activities and adjusted funds flow of $241.4 million and $260.4 million, respectively, compared to $196.0 million and $261.9 million, respectively, in the first quarter of 2022. Cash flow from operating activities increased from the prior year period primarily due to changes in non-cash working capital.

HIGHLIGHTS

• Adjusted funds flow was $260.4 million in the first quarter, which exceeded capital spending of $138.6 million, generating free cash flow⁽¹⁾ of $121.8 million
• Returned $66.6 million to shareholders through dividends and share repurchases in the first quarter; planning to return at least 60% of full-year 2023 free cash flow to shareholders (as previously indicated)
• Expect to complete remaining share repurchases of 3.3 million shares by end of July 2023, and renew normal course issuer bid for 10% of shares outstanding in August 2023, based on current market conditions
• Reduced net debt by 32% from year-end 2022, ending the quarter with net debt of $150.6 million
• First quarter production averaged 97.7 MBOE per day, including 56.7 Mbbl per day of liquids
• Production per share increased by 19% in the first quarter of 2023 compared to the same period in 2022

"Our strong operating performance has continued through the first quarter of 2023," said Ian C. Dundas, President and CEO. "We remain on track to efficiently execute our capital program which is designed to generate attractive free cash flow and deliver profitable growth. Priorities for free cash flow will continue to be focused on returning capital to shareholders and reinforcing the balance sheet."

FIRST QUARTER SUMMARY

Production in the first quarter of 2023 was 97,652 BOE per day, an increase of 6% compared to the same period a year ago, and 9% lower than the prior quarter. Crude oil and natural gas liquids production in the first quarter of 2023 was 56,734 barrels per day, in line with the same period a year ago, and 13% lower than the prior quarter. The higher production compared to the same period in 2022 was driven by the Company's 2022 development plan and strong well performance in North Dakota and the Marcellus. The lower production compared to the prior quarter was due to the planned sequencing of the Company's completions program in North Dakota with no operated wells brought online between mid-October 2022 and mid-February 2023. The sale of substantially all of Enerplus' Canadian assets in the fourth quarter of 2022 with associated production of 6,400 BOE per day (78% liquids) also contributed to the lower production in the first quarter of 2023 compared to the prior quarter.

Enerplus reported first quarter 2023 net income of $137.5 million, or $0.63 per share (basic), compared to net income of $33.2 million, or $0.14 per share (basic), in the same period in 2022. Excluding certain non-cash or non-recurring items, adjusted net income⁽¹⁾ for the first quarter of 2023 was $140.7 million, or $0.65 per share (basic), compared to $145.8 million, or $0.60 per share (basic), during the same period in 2022. First quarter 2023 net income was higher than the prior year period primarily due to a gain in commodity derivative instruments compared to a commodity derivative instrument loss in the prior year quarter.

Enerplus' first quarter 2023 realized Bakken oil price differential was $0.06 per barrel above WTI, compared to $0.35 per barrel below WTI in the first quarter of 2022. Enerplus is revising its 2023 Bakken crude oil price differential guidance to $0.50 per barrel above WTI, from $0.75 per barrel above WTI previously, reflecting the slightly weaker than expected pricing in the first quarter.

The Company's realized Marcellus natural gas price differential was $0.64 per Mcf below NYMEX during the first quarter of 2023, compared to $0.01 per Mcf above NYMEX in the first quarter of 2022. Enerplus expects its Marcellus differential to remain supported during spring and into summer due to a flat outlook on natural gas supply growth and weaker NYMEX pricing. As a result, Enerplus is maintaining its annual Marcellus differential guidance of $0.75 per Mcf below NYMEX.

Operating expenses were $10.56 per BOE in the first quarter of 2023, compared to $10.03 per BOE during the first quarter of 2022. The increase in per unit operating expenses compared to the prior year period was due to inflation adjusted contract pricing, increased gas processing volumes due to improved capture rates, and higher planned well service activity.

Current tax expense was $11.0 million in the first quarter.

Capital spending totaled $138.6 million in the first quarter of 2023. The Company paid $12.0 million in dividends in the quarter and repurchased approximately 3.5 million shares at an average price of $15.37 per share, for total consideration of $54.6 million. Subsequent to March 31, 2023, and up to and including May 3, 2023, Enerplus repurchased 1.1 million shares at an average price of $14.81 per share, for total consideration of $16.0 million.

Enerplus ended the first quarter of 2023 with total debt of $203.2 million and cash of $52.6 million. Enerplus was undrawn on its $1.3 billion credit facilities.

OPERATIONS

North Dakota production averaged 66,656 BOE per day during the first quarter of 2023, an increase of 16% compared to the same period a year ago. North Dakota production was 8% lower than the prior quarter due to the planned sequencing of the Company's completions program. During the first quarter, Enerplus drilled 14 gross operated wells (86% average working interest) and brought four gross operated wells (75% working interest) on production in North Dakota. In the second quarter, Enerplus expects to bring approximately 19 – 22 net operated wells on production in North Dakota, including 3 – 5 net refracs. The Company is continuing to operate two drilling rigs throughout 2023.

Marcellus production averaged 180 MMcf per day during the first quarter of 2023, approximately 11% higher than the same period in 2022 and approximately flat to the prior quarter.

RETURN OF CAPITAL TO SHAREHOLDERS

Enerplus remains committed to returning at least 60% of free cash flow generated in 2023 to shareholders through dividends and share repurchases. Based on current market conditions, the Company expects to continue to prioritize share repurchases for the majority of its return of capital plan and intends to complete share repurchases under its remaining normal course issuer bid ("NCIB") by the end of July 2023.  Enerplus expects to renew its NCIB in August 2023 for another 10% of the public float (within the meaning under the TSX rules).

As at May 3, 2023, Enerplus had 3.3 million shares remaining under its NCIB.

Enerplus announced a quarterly cash dividend of $0.055 per share payable on June 15, 2023 to shareholders of record on May 31, 2023.

Enerplus' current 2023 guidance is summarized below. The Company has updated guidance for its Bakken oil price differential to $0.50 per barrel above WTI (from $0.75 per barrel above WTI), production tax of 7% to 8% (from 7%), and transportation expense to $4.20 per BOE (from $4.35 per BOE).

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.

Basis of Presentation

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.

All references to "liquids" in this news release include light and medium crude oil, heavy oil and tight oil (all together referred to as "crude oil") and NGLs on a combined basis. All references to "natural gas" in this news release include conventional natural gas and shale gas on a combined basis.

Readers are urged to review the 2023 interim Management's Discussion & Analysis (MD&A) and financial statements, and 2022 MD&A and financial statements filed on SEDAR and as part of our Form 6-K and Form 40-F, respectively, on EDGAR concurrently with this news release for more complete disclosure on our operations.

The use of any of the words "expect", "anticipate", "continue", "estimate", "guidance", "ongoing", "may", "will", "project", "plans", "budget", "strategy" and similar expressions are intended to identify forward-looking information. In particular, but without limiting the foregoing, this news release contains forward-looking information pertaining to the following: 2023 production and capital spending guidance; Enerplus' return of capital plans, including expectations regarding payment of dividends and the source of funds related thereto; the funding of dividends and the share repurchase program from free cash flow; the anticipated percentage of free cash flow planned to be returned to shareholders; expectations regarding Enerplus' share purchase program, including the completion of the Company's current NCIB and the timing thereof; the anticipated renewal of the Company's NCIB based on current market conditions, including the timing and size thereof; expectations regarding the number of net operated wells brought on production in the second quarter of 2023; expected operating strategy in 2023 and expectations regarding our drilling program; oil and natural gas prices and differentials and expectations regarding the market environment and our commodity risk management program in 2023; 2023 Bakken and Marcellus differential guidance; expectations regarding realized oil and natural gas prices; and expected operating, transportation and cash G&A expenses and production taxes and 2023 guidance with respect thereto.

The forward-looking information contained in this news release reflects several material factors and expectations and assumptions of Enerplus including, without limitation: the ability to fund our return of capital plans, including both dividends at the current level and the share repurchase program, from free cash flow as expected; that our common share trading price will be at levels, and that there will be no other alternatives, that, in each case, make share repurchases an appropriate and best strategic use of our free cash flows; our ability to achieve, in a timely manner, all necessary regulatory approvals for the renewal of the Company's NCIB; that we will conduct our operations and achieve results of operations as anticipated; the continued operation of the Dakota Access Pipeline; that our development plans will achieve the expected results; that lack of adequate infrastructure will not result in curtailment of production and/or reduced realized prices beyond our current expectations; current and anticipated commodity prices, differentials and cost assumptions; the general continuance of current or, where applicable, assumed industry conditions, the impact of inflation, weather conditions and storage fundamentals; the continuation of assumed tax, royalty and regulatory regimes; the accuracy of the estimates of our reserve and contingent resource volumes; the continued availability of adequate debt and/or equity financing and adjusted funds flow to fund our capital, operating and working capital requirements, and dividend payments as needed; our ability to comply with our debt covenants; our ability to meet the targets associated with our credit facilities; the availability of third party services; expected transportation expenses; the extent of our liabilities; and the availability of technology and process to achieve environmental targets.

In addition, our 2023 guidance described in this news release is based on: a WTI price of $80.00/bbl, a NYMEX price of $3.00/Mcf, a Bakken crude oil price differential of $0.50/bbl above WTI, a Marcellus natural gas price differential of $0.75/Mcf below NYMEX and a CDN/USD exchange rate of 0.74. Enerplus believes the material factors, expectations and assumptions reflected in the forward-looking information are reasonable but no assurance can be given that these factors, expectations and assumptions will prove to be correct. Current conditions, economic and otherwise, render assumptions, although reasonable when made, subject to greater uncertainty.

NON-GAAP AND OTHER FINANCIAL MEASURES

Readers are referred to "Non-GAAP and Other Financial Measures" in Enerplus' first quarter 2023 MD&A for supplementary financial measures, which information is incorporated by reference to this new release.

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 net income" 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).

		Three months ended March 31,
($ millions)		2023						2022
Net income/(loss)		$		137.5				$		33.2
Unrealized derivative instrument, foreign exchange and marketable securities (gain)/loss				4.6						134.5
Other expense related to investing activities				—						13.1
Tax effect				(1.4)						(35.0)
Adjusted net income/(loss)		$		140.7				$		145.8

"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.

		Three months ended March 31,
($ millions)		2023			2022
Cash flow from/(used in) operating activities		$	241.4		$	196.0
Asset retirement obligation settlements			6.8			8.8
Changes in non-cash operating working capital			12.2			57.1
Adjusted funds flow		$	260.4		$	261.9
Capital spending			(138.6)			(99.0)
Free cash flow		$	121.8		$	162.9

Other Financial Measures

CAPITAL MANAGEMENT MEASURES

Capital management measures are financial measures disclosed by a company that (a) are intended to enable an individual to evaluate a company's objectives, policies and processes for managing the company's capital, (b) are not a component of a line item disclosed in the primary financial statements of the company, (c) are disclosed in the notes to the financial statements of the company, and (d) are not disclosed in the primary financial statements of the company. The following section provides an explanation of the composition of those capital management measures if not previously provided:

"Adjusted funds flow" is used by Enerplus and is useful to investors and securities analysts, in analyzing operating and financial performance, leverage and liquidity. 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.

"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. "Net debt" is useful to investors and securities analysts in analyzing financial liquidity and Enerplus considers net debt to be a key measure of capital management. For further details, see Note 5 to the Interim Financial Statements.

"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.

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.

"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.
