No offering of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended, or an exemption therefrom. Cautionary Statement Regarding Forward-Looking Statements This presentation includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements, other than statements of historical fact, included in this presentation that address activities, events or developments that the company expects, believes or anticipates will or may occur in the future are forward looking statements. The words “anticipates”, “plans”, “estimates”, “believes”, “expects”, “intends”, “will”, “should”, “may” and similar expressions may be used to identify forward-looking statements. Forward-looking statements may include, but are not limited to, statements relating to: our ability to execute our business strategies; the volatility of realized natural gas and oil prices; the level of production on our properties; estimates of quantities of natural gas, oil and NGL reserves and their values; general economic or industry conditions; legislation or regulatory requirements; conditions of the securities markets; our ability to raise capital; changes in accounting principles, policies or guidelines; financial or political instability; acts of war or terrorism; title defects in the properties in which we invest; and other economic, competitive, governmental, regulatory or technical factors affecting our properties, operations or prices. Although the Company believes the expectations reflected in these and other forward-looking statements are reasonable, the Company can give no assurance such statements will prove to be correct. Such forward-looking statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of the Company. These forward-looking statements involve certain risks and uncertainties that could cause the results to differ materially from those expected by the Company’s management. Information concerning these risks and other factors can be found in the Company’s filings with the Securities and Exchange Commission, including its Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, available on the Company's website or the SEC’s website at www.sec.gov. Readers are cautioned that any such statements are not guarantees of future performance and that actual results or developments may differ materially from those projected in the forward-looking statements. The forward-looking statements in this presentation are made as of the date hereof, and the Company does not undertake any obligation to update the forward-looking statements as a result of new information, future events or otherwise. Use of Non-GAAP Financial Information This presentation includes certain non-GAAP financial measures. Adjusted EBITDA is a supplemental non-GAAP measure that is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. PHX defines “Adjusted EBITDA” as earnings before interest, taxes, depreciation and amortization, or EBITDA, excluding unrealized gains (losses) on derivatives and gains (losses) on asset sales and including cash receipts from (payments on) off-market derivatives and restricted stock and deferred directors’ expense. PHX references Adjusted EBITDA in this presentation because it recognizes that certain investors consider Adjusted EBITDA a useful means of measuring our ability to meet our debt service obligations and evaluating our financial performance. Adjusted EBITDA has limitations and should not be considered in isolation or as a substitute for net income, operating income, cash flow from operations or other consolidated income or cash flow data prepared in accordance with GAAP. Because not all companies use identical calculations, the Company’s calculations of Adjusted EBITDA may not be comparable to similarly titled measures of other companies. Oil and Gas Reserves The SEC generally permits oil and gas companies, in filings made with the SEC, to disclose proved reserves, which are reserve estimates that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions, and certain probable and possible reserves that meet the SEC’s definitions for such terms. The Company discloses only estimated proved reserves in its filings with the SEC. The Company’s estimated proved reserves as of September 30, 2022, referenced in this presentation were prepared by Cawley, Gillespie and Associates, Inc, an independent engineering firm, and comply with definitions promulgated by the SEC. Additional information on the Company’s estimated proved reserves is contained in the Company’s filings with the SEC. Cautionary Statement Regarding Forward-Looking Statements

Overview PHX is a growth oriented mineral rights company focused on natural gas 3 In January of 2020, PHX Minerals began a dramatic company transformation: New management / technical team – deep industry experience New corporate strategy – minerals only from a “hybrid” New company name from the former Panhandle Oil & Gas – new name aligns with strategy New banking relationship – improved financial partner supporting acquisition strategy Former Company reserve footprint was scattered and consisted of both mature legacy nonop. working interest and royalty interest (~60% / 40% respectively when measured by proved reserve value) No catalyst to provide predictable / sustainable volume or reserve growth Commodity agnostic Since 2020, have high graded assets by divesting of virtually all of the material nonop. working interest assets and redeploying proceeds and free cash flow into mineral acquisition strategy Today, PHX is approximately 85% royalty volumes, 78% by proved reserves and 79% natural gas by volumes Transformation complete with sustainable model and balance sheet going forward

Improving Margins Driving Net Income & ROCE 6 The two key metrics used by PHX to measure the success of our royalties-only strategy and royalties acquisition program are: Return on Capital Employed (ROCE)1 NAV per share measure (the PV-10 value of our proved and probable reserves) Balance sheet management and ample liquidity underpin our strategy in order to thrive across the various pricing cycles of the energy sector 1 Defined as EBIT excluding non-cash gain/loss on derivatives, non-cash impairments, non-cash G&A, cash receipts from/payments on off-market derivatives and gain(losses) on asset sales divided by average debt and equity during the quarter 2 See Non-GAAP reconciliation in Appendix Royalties Only Strategy Non-operated Working interest Strategy 2

Per Share NAV Continues to Grow 7 NAV has consistently increased both on an absolute and per share basis (published in every corporate presentation since early 2021) since royalty-only strategy effort began under new management team Despite divesting of non-operated working interest, high grading assets with mineral acquisition program has grown PV10 value and increased NAV per share (net of debt) Below reserve value independently verified by DeGolyer & MacNaughton (2021) and Cawley, Gillespie and Associates, Inc (2022) Current asset base has lower risk and higher growth profile than the PHX pre-2020 legacy asset base Royalties Only Strategy Total 2P Reserve Value @ PV-10 ($ millions) NAV per Share Net of Debt Next Twelve Month NYMEX strip for oil and natural gas as of date reserves analysis was compiled

Definition of a Mineral Interest Illustrative Mineral Revenue Generation Unleased Minerals 100% owned by PHX PHX Issues a Lease PHX receives an upfront cash bonus payment and customarily a 20-25% royalty on production revenues In return, PHX delivers the right to explore and develop with the operator bearing 100% of costs for a specified lease term Leased Minerals Revenue Share PHX: 20-25% Operator: 75-80% Cost Share PHX: 0% Operator: 100% Lease Termination Upon termination of a lease, all future development rights revert to PHX to explore or lease again Process starts again from step 1 Minerals Perpetual real-property interests that grant hydrocarbon ownership under a tract of land Surface and mineral ownership have been negotiated in most cases over the decades Surface owners cannot legally prevent the development of minerals under most circumstances Represent the right to drill, and produce hydrocarbon or lease that right to third parties for an upfront payment and a negotiated percentage of production revenues ORRIs Overriding royalty interests Royalty interests that burden the working interests of a lease Right to receive a fixed, cost-free percentage of production revenue (term limited to life of leasehold estate) 1 2 3 4

Royalty Interests Versus Working Interests PHX believes that royalty assets provide a higher risk adjusted return compared to working interest assets Illustrative Margin Comparison Working Interest Mcfe Revenue $3.00 Less: Royalty Burden ($0.60)(1) Less: LOE ($1.00) Less: Taxes ($0.15) Less: Transportation ($0.25) Cash Margin ($) $1.00 Cash Margin (%) 33.0% Royalty Mcfe Revenue $3.00 Less: LOE - Less: Taxes ($0.15) Less: Transportation ($0.20)(2) Cash Margin ($) $2.65 Cash Margin (%) 88.0% Non-operated Working interest ownership bears one hundred percent of the development and production costs associated with a hydrocarbon well. Non-operated Working interest owners receive their share of the revenue after the royalty interest owners are paid. A mineral interest is real property that entitles the owner to all the rights associated with hydrocarbons below the surface in perpetuity. A royalty interest is created from a mineral interest and entitles the owner to receive a certain percentage of the gross revenue generated from the sales of the hydrocarbons without incurring development and operating costs. Royalty owner’s volumes come from working interest royalty burden 1 Assumes a 1/5 lease royalty burden 2 A portion of leases are cost free with all transportation costs paid by the operator

Royalty Interests Have Less Risk Than Working Interests 34 Both royalties and non-operated working interest asset classes have the same exposure to pricing cycles, however, Royalty assets have fewer risks when compared to other hydrocarbon asset classes The biggest risk associated with royalties is the lack of control over development timing Non-operated working interest assets have similar timing uncertainty as royalty owners Non-operated working interest assumes all cost to operate the well Royalty owners are not subject to lease operating expenses, SG&A overhead or workover expenses Increasing Risk Capex Exposure Operating Cost Exposure Environmental Liability Timing Risk Operator Bankruptcy Risk E&P (Non op Working Interest) E&P (Operated Working Interest) Royalties

Royalty Interests Trade At Higher Multiples Than Working Interests 35 Investors value working interest and royalty companies differently in the public markets Royalty companies trade at a premium to working interest companies primarily due to lower risk and lower capital intensity of the business Over time, PHX believes it should see an increase of its Enterprise Value / EBITDA ratio (adjusted for size) as the market recognizes the success of the royalties-only strategy Source: Stifel Nicolaus research note published on 05/01/2023

Minerals are Real Property Mineral and royalty interests are generally considered by law to be real property interests and are thus afforded additional protections under bankruptcy law Working Interest owner entitled to ~75-85% of production revenue based on royalty rate and bears 100% of development cost and lease operating expense Senior Debt Senior Secured Debt Equity Subordinated Debt Mineral Interest owner entitled to ~15-25% of production revenue based on royalty rate
