Disclaimer FORWARD-LOOKING STATEMENTS The information in this presentation and the oral statements made in connection therewith include “forward-looking statement” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of present or historical fact included in this presentation, regarding certain funds managed by Grey Rock Energy Management, LLC (“Grey Rock”), Executive Network Partnering Corporation (“ENPC”) (either as currently organized or as it may be reorganized into Granite Ridge Resources, Inc. (“Granite Ridge”) in connection with the transactions contemplated in this presentation), ENPC’s proposed business combination with Grey Rock, Grey Rock’s or ENPC’s ability to consummate the transaction, the benefits of the transaction and Granite Ridge’s, Grey Rock’s or ENPC’s future financial performance following the business combination as well as strategy, future operations, financial position, estimated revenues, and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. When used in this presentation, including any oral statements made in connection therewith, the words “could,” “should,” “will,” “may,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project,” the negative of such terms and other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on management’s current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events. Except as otherwise required by applicable law, Grey Rock disclaims any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this presentation. Grey Rock cautions you that these forward-looking statements are subject to all the risks and uncertainties, most of which are difficult to predict and many of which are beyond the control of Grey Rock, incident to the development, production, gathering and sale of oil and natural gas. These risks include but are not limited to, commodity price volatility, low prices for oil and/or natural gas, global economic and geopolitical conditions, inflation, increased operating costs, lack of availability of drilling and production equipment, supplies services and qualified personnel, processing volumes and pipeline throughput, and certificates related to new technologies, geographical concentration of operations, environmental risks, weather risks, security risks, drilling and other operating risks (including those of Grey Rock’s third-party operators), regulatory changes, the uncertainty inherent in estimating oil and natural gas reserves and in projecting future rates of production, reductions in cash flow, lack of access to capital, Grey Rock’s, ENPC’s or Granite Ridge’s ability to satisfy future cash obligations, restrictions in existing or future debt agreements, the timing of development expenditures, managing growth and integration of acquisitions, failure to realize expected value creation from property acquisitions, the defects and limited control over non-operated properties. Should one or more of the risks or uncertainties described in this presentation and the oral statements made in connection therewith occur, or should underlying assumptions prove incorrect, actual results and plans could differ materially from those expressed in any forward-looking statements. Additional information concerning these and other factors that may impact ENPC’s operations can be found in its periodic filings with the Securities and Exchange Commission (the “SEC”), including its Annual Report on Form 10-K for the fiscal year ended December 31, 2021. ENPC’s SEC filings are available publicly on the SEC’s website at www.sec.gov. NO OFFER OR SOLICITATION This presentation does not constitute an offer to sell or the solicitation of an offer to buy any securities or a solicitation of any vote or approval, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offer of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act. PARTICIPANTS IN THE SOLICITATION Grey Rock, ENPC, Granite Ridge and their respective directors and executive officers may be deemed to be participants in the solicitation of proxies from the shareholders of ENPC in connection with the proposed business combination.

Investors and security holders will be able to obtain the documents, and any other documents ENPC or Granite Ridge has filed with the SEC, free of charge at the SEC’s website, www.sec.gov. In addition, documents filed with the SEC by ENPC and Granite Ridge will be available free of charge by writing ENPC at 137 Newbury Street, 7th Floor, Boston, MA 02116, Attention: Investor Relations. RESERVE INFORMATION Reserve engineering is a process of estimating underground accumulations of hydrocarbons that cannot be measured in an exact way. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data, and price and cost assumptions made by reserve engineers. In addition, the results of drilling testing and production activities may justify revisions of estimates that were made previously. If significant, such revisions could impact Grey Rock’s strategy and change the schedule of any further production and development drilling. Accordingly, reserve estimates may differ significantly from the quantities of oil and natural gas that are ultimately recovered. Estimated Ultimate Recoveries, or “EURs,” refer to estimates of the sum of total gross remaining proved reserves per well as of a given date and cumulative production prior to such given date for developed wells. These quantities do not necessarily constitute or represent reserves as defined by the SEC and are not intended to be representative of all anticipated future well results. This presentation contains volumes and PV-10 values of our proved reserves and unproved reserves. The SEC strictly prohibits companies from aggregating proved, probable and possible reserves in filings with the SEC due to the different levels of certainty associated with each reserve category. The SEC also prohibits companies from including resources that are not proved, probable or possible reserves in filings with the SEC. Investors should be cautioned that estimates of volumes and PV-10 values of resources other than proved reserves are inherently more uncertain than comparable measures for proved reserves. Further, because estimated proved reserves and unproved resources have not been adjusted for risk due to this uncertainty of recovery, their summation may be of limited use. USE OF PROJECTIONS This presentation contains projections for Grey Rock, including with respect to its EBITDA, net debt to EBITDA ratio, capital expenditures, free cash flow and net revenues as well as its production volumes. Grey Rock’s independent auditors have not audited, reviewed, compiled or performed any procedures with respect to the projects for the purpose of their inclusion in this presentation, and accordingly, have not expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this presentation. These projection are for illustrative purposes only and should not be relied upon as being necessarily indicative of future results. In this presentation, certain of the above-mentioned projected information has been repeated (in each case, with an indication that the information is subject to the qualifications presented herein).

Disclaimer USE OF NON-GAAP FINANCIAL MEASURES This presentation includes certain financial measures that are not calculated in accordance with U.S. generally accepted accounting principles (“GAAP”). These measures include (i) EBITDA, (ii) net debt, (iii) free cash flow and (iv) PV-10. These non- GAAP financial measures are not measures of financial performance prepared or presented in accordance with GAAP and may exclude items that are significant in understanding and assessing our financial results. Therefore, these measures should not be considered in isolation, and users of any such information should not place undue reliance thereon. The computations of EBITDA and free cash flow may not be comparable to other similarly titled measures of other companies. EBITDA should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP or as an indicator of operating performance. Certain items excluded from EBITDA are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic costs of depreciable assets, none of which are components of EBITDA. Grey Rock’s presentation of EBITDA should not be construed as an inference that its results will be unaffected by unusual or non-recurring terms. In addition, free cash flow does not represent the residual cash flow available for discretionary expenditures. Grey Rock believes that free cash flow is useful to investors as a measure of the ability of the business to generate cash. This presentation contains PV-10, a supplemental financial measure not presented in accordance with GAAP. PV-10 reflects the present value of estimated future net revenues to be generated from the production of proved reserves, determined in accordance with the rules and regulations of the SEC, without giving effect to non-property related expenses, discounted at 10% per year before income taxes. GAAP does not prescribe any corresponding measure for PV-10 as of an interim date or on any basis other than SEC prices. INDUSTRY AND MARKET DATA Although all information and opinions expressed in this presentation, including market data and other statistical information (including estimates and projections relating to addressable markets), were obtained from sources believed to be reliable and are included in good faith, none of Grey Rock, Granite Ridge or ENPC has independently verified the information and makes no representation or warranty, express or implied, as to its accuracy or completeness. Some data is also based on the good faith estimates of Grey Rock or ENPC, which are derived from their review of internal sources as well as the independent sources described above. This presentation contains preliminary information only, is subject to change at any time and, is not, and should not be assumed to be, complete or to constitute all the information necessary to adequately make an informed decision.
