HOUSTON, Texas, March 3, 2025—Chord Energy Corporation (NASDAQ: CHRD) (the “Company,” “we,” “us,” or “our”), announced today that, subject to market conditions, it intends to offer $750 million in aggregate principal amount of senior unsecured notes due 2033 (the “New Notes”) in a private placement to eligible purchasers (the “Notes Offering”). The New Notes will be unsecured, senior obligations of the Company and will be guaranteed by the Company’s existing subsidiaries and future domestic subsidiaries that, in each case, guarantee the Company’s senior secured revolving credit facility (the “Credit Facility”).

The Company intends to use the net proceeds from the Notes Offering for purposes of (i) financing its concurrent cash tender offer (the “Tender Offer”) for any and all of its outstanding 6.375% senior unsecured notes due 2026 (the “2026 Notes”) that are validly tendered and accepted for purchase in the Tender Offer, (ii) redeem any 2026 Notes, to the extent any 2026 Notes remain outstanding following the Tender Offer, on or about June 1, 2025 at a redemption price of 100.000% of the principal amount thereof, plus accrued and unpaid interest, if any, to the redemption date, (iii) repay a portion of its borrowings outstanding under the Company’s Credit Facility, and (iv) pay all fees and expenses associated therewith. The final terms and amounts of the New Notes are subject to market and other conditions and may be materially different than expectations. The Notes Offering is not conditioned on the Tender Offer, but the Tender Offer is conditioned on the Notes Offering.

The New Notes have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws and unless so registered, the notes may not be offered or sold in the United States absent an applicable exemption from, or a transaction not subject to, registration requirements of the Securities Act and applicable state securities laws. The New Notes are being offered and sold only to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act and to non-U.S. persons outside the United States pursuant to Regulation S under the Securities Act.

This press release is being issued pursuant to Rule 135c under the Securities Act and is for informational purposes only. This press release does not constitute (i) a notice of redemption or satisfaction and discharge under the indenture governing the 2026 Notes or (ii) an offer to sell or the solicitation of an offer to buy any security, including with respect to the 2026 Notes and the New Notes, and shall not constitute an offer, solicitation or sale in any jurisdiction in which such offering, solicitation or sale would be unlawful.

Exhibit 99.3

UNAUDITED PRO FORMA CONDENSED COMBINED STATEMENT OF OPERATIONS

On May 31, 2024, Chord Energy Corporation (“Chord” or the “Company”) completed the arrangement contemplated by the arrangement agreement, dated as of February 21, 2024 (the “Arrangement Agreement”), by and among Chord, Enerplus Corporation (“Enerplus”) and Spark Acquisition ULC, a wholly-owned subsidiary of Chord (such transaction, the “Arrangement”). Pursuant to the Arrangement Agreement, each Enerplus shareholder received 0.10125 shares of common stock of Chord, par value of $0.01 per share (the “Chord Common Stock”) and $1.84 in cash, in exchange for each Enerplus common share held as of May 31, 2024.

Chord and Enerplus prepared their respective historical financial statements in accordance with U.S. GAAP. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations (“ASC 805”), Chord was treated as the acquirer for accounting purposes and accounted for the Arrangement as an acquisition of a business.

The effects of the Arrangement were included in the Company’s audited historical consolidated balance sheet as of December 31, 2024; therefore, a pro forma balance sheet is not included herein. The Company’s audited historical consolidated statement of operations for the year ended December 31, 2024 includes the effects of the Arrangement from May 31, 2024 through December 31, 2024. The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2024 was prepared as if the Arrangement had occurred on January 1, 2024. The unaudited pro forma condensed combined statement of operations has been derived from the historical consolidated financial statements of the Company and Enerplus.

The unaudited pro forma condensed combined statement of operations and underlying pro forma adjustments are based upon currently available information and include certain estimates and assumptions made by the Company’s management; accordingly, actual results could differ materially from the pro forma information. Significant estimates and assumptions include the preliminary purchase price allocation, based on estimates of, and assumptions related to, the fair value of the assets acquired and liabilities assumed as of May 31, 2024. Management believes that the assumptions used to prepare the unaudited pro forma condensed combined statement of operations and accompanying notes provide a reasonable and supportable basis for presenting the significant estimated effects of the Arrangement. The following unaudited pro forma condensed combined statement of operations does not purport to represent what the Company’s results of operations would have been if the Arrangement had occurred on January 1, 2024. The unaudited pro forma condensed combined statement of operations should be read together with the following:

The unaudited pro forma condensed combined statement of operations has been prepared in accordance with Article 11 of SEC Regulation S-X as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses,” using assumptions set forth in the notes herein. Article 11 permits presentation of reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur (“Management’s Adjustments”). The Company has elected not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in the unaudited pro forma condensed combined statement of operations.

Pro Forma Condensed Combined Statement of Operations (Unaudited)

Year Ended December 31, 2024

(In thousands, except per share data)

The accompanying notes are an integral part of the unaudited pro forma condensed combined statement of operations.

Notes to Unaudited Pro Forma Condensed Combined Statement of Operations

The unaudited pro forma condensed combined statement of operations has been prepared in accordance with Article 11 using assumptions set forth in the notes herein. Article 11 permits presentation of reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur, otherwise known as Management’s Adjustments. The Company has elected not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in the unaudited pro forma condensed combined statement of operations.

On May 31, 2024, the Arrangement was completed, and the Company issued 20,680,097 shares of Chord Common Stock and paid $375.8 million in cash to Enerplus shareholders. Pursuant to the Arrangement Agreement, each Enerplus shareholder received 0.10125 shares of Chord Common Stock and $1.84 in cash, in exchange for each Enerplus common share held as of May 31, 2024. The Arrangement was accounted for using the acquisition method of accounting in accordance with ASC 805, with Chord treated as the accounting acquirer. The Company’s preliminary allocation of the purchase price with respect to the Arrangement is based on estimates of, and assumptions related to, the fair value of the assets acquired and liabilities assumed as of May 31, 2024. As provided under ASC 805, the purchase price allocation may be subject to change for up to one year after May 31, 2024. Certain estimated values for the acquisition, including oil and natural gas properties, are not yet finalized and are subject to revision as additional information becomes available and more detailed analyses are completed. Accordingly, the pro forma adjustments are preliminary, have been made solely for the purpose of providing pro forma financial information and are subject to revision based on a final determination of fair value as of the closing date of the Arrangement. Differences between preliminary estimates and the final allocation of the consideration paid may have a material impact on the accompanying unaudited pro forma condensed combined statement of operations.

The effects of the Arrangement were included in the Company’s audited historical consolidated balance sheet as of December 31, 2024; therefore, a pro forma balance sheet is not included herein. The Company’s audited historical consolidated statement of operations for the year ended December 31, 2024 includes the effects of the Arrangement from May 31, 2024 through December 31, 2024. The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2024 was prepared as if the Arrangement had occurred on January 1, 2024. The unaudited pro forma condensed combined statement of operations has been derived from the historical consolidated financial statements of the Company and Enerplus.

For purposes of preparing the unaudited pro forma condensed combined statement of operations, certain pro forma adjustments were translated from Canadian dollars to United States dollars using historical exchange rates.

The unaudited pro forma condensed combined statement of operations and underlying pro forma adjustments are based upon currently available information and include certain estimates and assumptions made by management; accordingly, actual results could differ materially from the pro forma information. Management believes the assumptions provide a reasonable and supportable basis for presenting the estimated significant effects of the transactions described above. The unaudited pro forma condensed combined statement of operations is provided for illustrative purposes only and may or may not provide an indication of results in the future.

Certain reclassifications have been made in the historical presentation of Enerplus’ statement of operations to conform to the Company’s historical presentation.

Statement of Operations for the five months ended May 31, 2024

The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2024 reflects the following adjustments:

A 0.125% change in the variable interest rate of Chord’s revolving credit facility or a $10 million change in the amount financed would increase or decrease interest expense presented in the unaudited pro forma condensed combined statement of operations for the year ended December 31, 2024 by $0.2 million and $0.3 million, respectively.
