Item 8.01

Other Events.

On June 22, 2023, Granite Ridge Resources, Inc., a Delaware corporation (“Granite Ridge” or the “Company”), consummated the closing of the Company’s previously announced exchange offer (the “Offer”) relating to its outstanding warrants to purchase shares of common stock of the Company, par value $0.0001 per share (the “Common Stock”), which warrants trade on the New York Stock Exchange under the symbol “GRNT.WS” (the “Warrants”). The Company also consummated the closing of the consent solicitation related to the Offer, which solicited consents from holders of the Warrants to amend that certain Warrant Agreement, dated as of September 15, 2020, by and between Executive Network Partnering Corporation, a Delaware corporation (“ENPC”), and Continental Stock Transfer & Trust Company, as warrant agent (“Continental”), as amended on March 24, 2021, by and between ENPC and Continental, and as assigned pursuant to the Assignment, Assumption and Amendment Agreement, dated as of October 24, 2022, by and between Granite Ridge, ENPC and Continental (as amended and assigned, the “Warrant Agreement”) to permit the Company to require that each Warrant that is outstanding upon the closing of the Offer be exchanged for 0.225 shares of Common Stock, which is a ratio 10% less than the exchange ratio applicable to the Offer (such amendment, the “Warrant Amendment”). The Company issued 2,471,738 shares of Common Stock in exchange for the Warrants tendered in the Offer.

As previously announced, the Company exercised its right, in accordance with the terms of the Warrant Amendment, to exchange each Warrant that is outstanding upon the closing of the Offer for 0.225 shares of Common Stock per Warrant (the “Post-Offer Exchange”). The Company fixed the date for the Post-Offer Exchange as July 5, 2023.

Cautionary Statement Regarding Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of the federal securities laws, including statements regarding the expected consummation of the Post-Offer Exchange. These forward-looking statements generally are identified by the words “believe,” “project,” “expect,” “anticipate,” “estimate,” “intend,” “strategy,” “future,” “opportunity,” “plan,” “may,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result,” and similar expressions, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements are predictions, projections, and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Many factors could cause actual future events to differ materially from the forward-looking statements in this Current Report on Form 8-K, including, but not limited to those described under the section entitled “Risk Factors” in the Company’s registration statement on Form S-4/A, filed June 5, 2023, as such factors may be updated from time to time in the Company’s periodic filings with the SEC, which are accessible on the SEC’s website at www.sec.gov.

New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this Current Report on Form 8-K may not occur and actual results could differ materially and adversely from those anticipated.

Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and we assume no obligation and do not intend to update or revise these forward-looking statements, whether as a result of new information, future events or otherwise. We do not give any assurance that we will achieve our expectations.
