6.Transact such other business as may properly come before the Annual Meeting or any adjournment or postponement thereof.

The holders of our Series A Preferred Stock will vote with the holders of our common stock on an as-converted basis, voting together as a single class, on the matters set forth above. All stockholders of record at the close of business on April 13, 2026, the record date for the Annual Meeting (the “Record Date”), will be entitled to notice of and to vote at the Annual Meeting, subject to the Conversion Limitation (as defined below) applicable to the Series A Preferred Stock.

Table of Contents

Instead of mailing a printed copy of the proxy materials, including our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (“Annual Report”), to each stockholder of record, we are providing access to these materials via the internet. This reduces the amount of paper necessary to produce these materials, as well as the costs associated with mailing these materials to all stockholders. Accordingly, on or about April 24, 2026, a Notice Regarding the Internet Availability of Proxy Materials (the “Notice”) was mailed to our stockholders of record as of the Record Date. The Notice contains instructions on how to electronically access the proxy materials on the internet and how to vote your shares. Instructions for requesting a paper copy of the proxy materials are also contained in the Notice.

Your vote is important. Whether or not you expect to virtually attend the Annual Meeting, please vote as promptly as possible by using the internet or telephone voting procedures described in the Notice and in this Proxy Statement or by requesting a printed copy of the proxy materials (including the proxy card) and completing, signing and returning the enclosed proxy card by mail.

PROPOSAL 1: DIRECTOR ELECTION PROPOSAL

The Board currently consists of ten members, including one member appointed by funds affiliated with Carnelian Energy Capital Management, L.P. (“Carnelian”) pursuant to the Certificate of Designation (as defined herein) (the “Series A Director”). The number of members of our Board is determined from time-to-time by resolution of the Board and is currently set at eleven. The Board is not classified and all of our directors, other than the Series A Director, are elected annually for one-year terms, until his or her successor shall be elected and qualified, or his or her earlier death, resignation, retirement, disqualification or removal from office.

Each of the eight director nominees will be voted upon by the holders of our common stock and, subject to the Conversion Limitation, the holders of our Series A Preferred Stock, voting together as a single class. Proxies solicited by the Board will be exercised for the election of each of the director nominees, unless you vote “withhold” with respect to one or more of the nominees. The eight director nominees for election at the Annual Meeting are identified below. Each of the current directors, other than David Sproule who was not nominated for re-election at the end of his current term, has been nominated for election by the Board upon recommendation by the Nominating, Governance and Sustainability Committee of our Board (the “NGS Committee”) and has decided to stand for election, and, if elected to the Board, will serve until the Company’s 2027 annual meeting of stockholders. Mr. Sproule intends to serve on the Board through the end of his current term on the date of the Annual Meeting.

If prior to the Annual Meeting a nominee becomes unavailable to serve as a director, any shares represented by a proxy directing a vote will be voted for the remaining nominees and for any substitute nominee(s) designated by the Board.

The NGS Committee is also tasked with identifying the qualifications, qualities, skills, and other expertise required to be a director and to identify and screen individuals qualified to become members of the Board, consistent with the criteria determined by the NGS Committee to be considered in selecting director nominees. The NGS Committee shall review the contributions and qualifications of incumbent directors in determining whether to recommend that the Board nominate them for reelection to the Board.

Table of Contents

The NGS Committee and the Board monitor the mix of specific experience, qualifications and skills of our directors in order to ensure that the Board, as a whole, has the necessary tools to perform its oversight function effectively. We are committed to building a well-rounded Board comprised of individuals from different backgrounds, including differences in viewpoints, education, experience and other individual qualifications and attributes.

Board Role in Risk Oversight

As an oil and gas exploration and production company, we encounter a variety of risks, including, among others, commodity price volatility and supply and demand risks, risks associated with rising costs of doing business, legislative and regulatory risks, availability of capital and financing, risks associated with our development, acquisition and production activities, environmental and weather-related risks, cybersecurity risks and risks associated with political instability.

The NYSE listing rules require that a majority of the board of directors of a company listed on the NYSE be composed of “independent directors,” which is generally defined as a person who the board of directors determines has no “material relationship” with the company. Our Board has determined that Steven Cobb, Katherine Gallagher, Scott Gieselman, Steven Gray, Matthew Kelly, Scott McNeill, David Poole and Billy Quinn are independent within the meaning of the NYSE listing rules. Our Board has affirmatively determined that: (i) Messrs. Gieselman, Gray and Poole, the current members of our Compensation Committee, meet the definition of “independent director” for purposes of serving on a compensation committee under the NYSE listing rules; and (ii) Messrs. Gieselman, McNeill and Poole and Ms. Gallagher, the current members of the Audit Committee, meet the definition of “independent director” for purposes of serving on an audit committee under the NYSE listing rules and are “independent” under Rule 10A-3 of the Exchange Act. In making these independence determinations, our Board reviewed and discussed information provided by the directors with regard to each director’s business and personal activities and relationships as they may relate to us and our management, including the beneficial ownership of our capital stock by each non-employee director or entities with which they are affiliated. In addition to determining whether each director satisfies the director independence requirements set forth in the NYSE listing requirements, in the case of members of our audit committee, our Board has also made an affirmative determination that members satisfy the separate independence requirements under the NYSE and SEC rules for such members.

In evaluating a director candidate’s qualifications, the Board assesses whether such a candidate possesses the integrity, judgment, knowledge, experience, skills and expertise that are likely to enhance our ability to manage and direct our affairs and business, including the committees of the Board. Our directors hold office until the earlier of their death, resignation, retirement, disqualification or removal or until their successors have been duly elected and qualified.

Board Leadership Structure

Our Corporate Governance Guidelines set forth the policy with respect to the separation of the offices of chairperson of the Board (the “Chairperson”) and Chief Executive Officer. The Board will periodically appoint a Chairperson. Under our Corporate Governance Guidelines, the Chairperson and the CEO role may be filled by the same individual. In the event the Chairperson is not independent, the Board will select a lead independent director who will have authority to, among other things, serve as liaison between the Chairperson and the independent directors, lead executive sessions of the Board, call meetings of the independent directors, and approve meeting agendas, schedules and information sent to the Board.

The Board currently maintains a leadership structure whereby the Chairperson is an independent director. The Board believes that having a Chairperson who is independent of management provides strong leadership for the Board and helps ensure critical and independent thinking with respect to our strategy and performance. Our CEO is also a member of the Board, and the Board anticipates that our CEO will be nominated annually to serve on the Board. We believe this is important to make information and insight directly available to the directors in their deliberations. The Board believes that its current leadership structure provides an appropriate, well-functioning balance between non-management and management directors that combines experience, accountability and effective risk oversight.

We will appropriately disclose the name of the Chairperson and any lead independent director and the method by which interested parties may contact the independent Chairperson, any lead independent director or the independent directors as a group. The Board conducts an annual assessment of its leadership structure to determine that the leadership structure is the most appropriate for the Company at the time, taking into account the recommendations of the NGS Committee.

Succession Planning

The NGS Committee oversees and approves plans for succession planning. As it relates to CEO and CFO succession planning, the NGS Committee identifies the qualities and characteristics necessary for an effective CEO or CFO and monitors and reviews the development and progression of potential candidates against these standards. The NGS Committee also regularly consults with our CEO on senior management succession planning.

Plurality Voting in Director Elections

Our Bylaws provide that directors, other than the Series A Director, are elected by a plurality of the votes cast in respect of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. The plurality voting standard does not require a director nominee to receive a majority of the votes cast in order to be elected. Under a plurality voting standard, the director nominees who receive the greatest number of votes cast “FOR” their election are elected as directors, up to the maximum number of directors to be elected at the meeting. Votes “WITHHELD” with respect to any director nominee and broker non-votes, if any, will not be counted as votes cast for purposes of the election of directors and therefore will have no effect on the outcome of the election. Stockholders do not have cumulative voting rights in the election of directors.

Pursuant to the Certificate of Designation, Carnelian has the exclusive right to appoint and elect the Series A Director.

Board Meetings

Our Board conducts its business through meetings of the Board, actions taken by written consent in lieu of meetings and by the actions of its committees. During 2025, the Board held five meetings and each of our directors attended at least 80% of the meetings of the Board and the Board committees on which they served.

Committees of the Board

The Board currently has three standing committees: the Audit Committee, the Compensation Committee and the Nominating, Governance and Sustainability Committee. Each of the committees reports to the Board as it

AUDIT COMMITTEE REPORT

While the Audit Committee has the responsibilities and powers set forth in its charter, and the Company’s management and the independent registered public accounting firm are accountable to the Audit Committee, it is not the duty of the Audit Committee to plan or conduct audits or to determine that the Company’s financial statements and disclosures are complete and accurate and in accordance with generally accepted accounting principles and applicable laws, rules and regulations.

The Audit Committee has reviewed and discussed with management of the Company and Deloitte & Touche LLP, the Company’s independent registered public accounting firm, the audited financial statements of the Company for the fiscal year ended December 31, 2025 (the “Audited Financial Statements”).

The Audit Committee has discussed with Deloitte & Touche LLP the matters required to be discussed by the Public Company Accounting Oversight Board (PCAOB) Auditing Standard No. 1301, as in effect on the date of this Proxy Statement.

The Audit Committee has: (1) considered whether non-audit services provided by Deloitte & Touche LLP are compatible with its independence; (2) received the written disclosures and the letter from Deloitte & Touche LLP required by the applicable requirements of the PCAOB regarding Deloitte & Touche LLP’s communications with the Audit Committee concerning independence; and (3) discussed with Deloitte & Touche LLP its independence.

Long-Term Equity Incentive Compensation

Recapitalization of Incentive Units

We granted long-term equity incentive awards to Messrs. Arnold and Sproule in the form of membership interests in INR Holdings on July 17, 2024 (the “2024 Incentive Units”) and in 2017 (the “2017 Incentive Units,” and together with the 2024 Incentive Units, the “Incentive Units”), that were intended to constitute profits interests for U.S. federal income tax purposes. The Incentive Units were subject to time- and performance-based vesting requirements. In connection with the closing of the IPO on February 3, 2025, all outstanding unvested Incentive Units (which automatically vested) and vested Incentive Units were recapitalized into common units representing limited liability company interests in INR Holdings (“INR Units”).

Omnibus Incentive Plan

Our Named Executive Officers are eligible to participate in the Omnibus Plan, which provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), performance stock units (“PSUs”), stock awards, dividend equivalents, other stock-based awards, cash awards and substitute awards. The purpose of the Omnibus Plan is to align the interests of our eligible service providers, including our Named Executive Officers, with those of our stockholders. The awards made to our Named Executive Officers under the Omnibus Plan are discussed below.

In connection with the IPO, Mr. Wolfe received a one-time grant of 62,500 RSUs, which vested in full on February 3, 2026. In addition, on March 17, 2025, Messrs. Arnold and Sproule each received an annual grant of 130,586 PSUs and Mr. Wolfe received an annual grant of 43,529 PSUs and 43,529 RSUs.

Stock Ownership Guidelines

Effective November 2025, the Compensation Committee approved the adoption of stock ownership guidelines for Infinity’s named executive officers and non-employee directors. The stock ownership guidelines are intended to further align the interests of our non-employee directors and named executive officers with the interests of our stockholders. Under this policy, our named executive officers and non-employee directors must hold shares of our common stock equal to a multiple, based upon position, of their base salary or annual cash retainer, as applicable. The multiples applicable to our executive officers and non-employee directors are as follows:

•Chief Executive Officer and Chief Financial Officer, 5x base salary;

•Other Named Executive Officers, 3x base salary; and

•Non-employee Directors, 5x annual cash retainer.

Covered individuals who are subject to the guidelines are required to achieve the applicable stock ownership requirement within five years after first becoming subject to the guidelines. All covered individuals shall retain a minimum of 50% of the net shares issued upon vesting of equity-based awards to him or her pursuant to any equity incentive plan of the Company until they achieve compliance with the guidelines.

The following holdings count towards compliance with our stock ownership guidelines:

•Shares acquired via open market purchase or owned directly (or through a family trust);

•Deferred stock units;

Employee and Retirement Benefits

We currently provide broad-based health and welfare benefits, including health, life, vision, and dental insurance, to our full-time employees, including our Named Executive Officers. In addition, we currently make available a retirement plan intended to provide benefits under Section 401(k) of the Code, pursuant to which employees (including our Named Executive Officers) may elect to defer a portion of their compensation on a pre-tax basis and have it contributed to the plan. Pre-tax contributions are allocated to each participant’s individual account and are then invested in selected investment alternatives according to the participant’s directions. We match 100% of elective deferrals up to a maximum per participant per calendar year equal to 5% of the participant’s eligible compensation, in addition to making non-elective employer contributions. Matching contributions to our 401(k) plan are not subject to vesting requirements. All contributions under our 401(k) plan are subject to certain annual dollar limitations in accordance with applicable laws, which are periodically adjusted for changes in the cost of living. Other than the 401(k) plan, we do not provide any qualified or non-qualified retirement or deferred compensation benefits to our employees, including our Named Executive Officers.

Potential Payments Upon Termination or Change in Control

Executive Severance Plan

On February 3, 2025, the Compensation Committee of the Board adopted the Infinity Natural Resources, Inc. Executive Change in Control and Severance Plan (the “Executive Severance Plan”). The Executive Severance Plan provides severance pay and benefits to eligible officers and management employees, including Messrs. Arnold, Sproule and Wolfe. Capitalized terms used but not otherwise defined herein have the meanings assigned to them in the Executive Severance Plan.

Upon the termination of a Named Executive Officer’s employment due to a termination by the Company without Cause or a resignation by the Named Executive Officer for Good Reason (each, a “Qualifying Termination”) that occurs outside of the period commencing on the date on which a Change in Control is consummated and ending 24 months after a Change in Control is consummated (the “Change of Control Protection Period”), the Named Executive Officer would be entitled to receive the following severance benefits: (i) a cash severance payment equal to the product of (a) the sum of the Named Executive Officer’s base salary and target annual bonus for the year of termination (the “Annual Compensation”) and (b) the Applicable Non-CIC Severance Multiple (which is 1.5 for Messrs. Arnold and Sproule, and 1.0 for Mr. Wolfe), payable in substantially equal installments over 18 months for Messrs. Arnold and Sproule, and 12 months for Mr. Wolfe, (ii) any earned but unpaid annual bonus with respect to the prior completed calendar year (if any, the “Earned Annual Bonus”), (iii) a pro-rated portion of such Named Executive Officer’s annual bonus for the current calendar year determined based on actual performance levels (the “Pro-Rated Bonus”) and (iv) a cash payment equal to the product of (a) the monthly amount of the premiums for the Named Executive Officer’s group health plan coverage plans (the “Monthly COBRA Amount”) and (b) 18 for Messrs. Arnold and Sproule, and 12 for Mr. Wolfe.

Upon the termination of a Named Executive Officer’s employment due to a Qualifying Termination that occurs during a Change of Control Protection Period, the Named Executive Officer would be entitled to receive the following severance benefits, payable in lump sum within 60 days after such Named Executive Officer’s date of termination: (i) a cash severance payment equal to the product of (a) the Annual Compensation and (b) 2.5 for Messrs. Arnold and Sproule, and 1.5 for Mr. Wolfe, (ii) the Earned Annual Bonus, (iii) the Pro-Rated Bonus and (iv) a cash payment equal to the product of (a) the Monthly COBRA Amount and (b) 24 for Messrs. Arnold and Sproule, and 18 for Mr. Wolfe.

Payment of any severance benefits under the Executive Severance Plan to a Named Executive Officer is subject to the Named Executive Officer’s (i) execution and non-revocation of a general release of claims in favor of the Company and (ii) continued compliance with the cooperation covenant set forth in the Executive Severance Plan and the other restrictive covenant obligations set forth in the Named Executive Officer’s participation agreement and any other agreement to which the Named Executive Officer is a party.

Equity Award Treatment

Pursuant to the terms of the Omnibus Plan and applicable award agreements, if a Named Executive Officer’s employment terminates due to death or disability, then upon the applicable termination date their unvested RSUs will accelerate and vest in full and their unvested PSUs will vest pro rata (with such vesting deemed to be achieved at target performance). If a Named Executive Officer’s employment is terminated by the Company without Cause or by the Named Executive Officer for Good Reason (each, as defined in the applicable award agreement), then (i) upon the applicable termination date, their unvested RSUs will vest pro rata and (ii) their unvested PSUs will remain eligible to vest pro rata at the end of the performance period (with such vesting based on actual performance).

In the event of a Change in Control (as defined in the Omnibus Plan) in which the surviving entity assumes the unvested portion of the RSUs and/or the PSUs, and if the Named Executive Officer’s employment is terminated by the Company without Cause or by the Named Executive Officer for Good Reason within 24 months following such Change in Control, then 100% of the then-unvested RSUs will immediately accelerate and vest, and the then-unvested PSUs will accelerate and vest (with such vesting deemed to be achieved at the greater of target and actual performance for the PSUs).

In the event of a Change in Control in which the surviving entity does not assume the unvested portion of any RSUs and/or the PSUs, then 100% of the then-unvested RSUs will immediately accelerate and vest, and the then-unvested PSUs will accelerate and vest (with such vesting deemed to be achieved at the greater of target and actual performance for the PSUs).

Policies and Practices Related to the Grant of Option Awards

Following our IPO, the Company has not granted stock options, stock appreciation rights, or similar option-like instruments. Accordingly, the Company has no specific policies or practices regarding the timing of such awards in relation to the Company’s disclosure of material nonpublic information. In the event the Company decides to grant such awards in the future, the Board and the Compensation Committee will consider appropriate practices and policies with respect to the foregoing.

DIRECTOR COMPENSATION

In connection with the closing of the IPO, we adopted a non-employee director compensation policy (the “Director Compensation Policy”), pursuant to which our non-employee directors are eligible to receive compensation for their services on our Board.

Our non-employee directors may elect to receive their annual retainers in the form of additional RSUs (which will be subject to the same vesting schedule as the annual RSU grants described below) or in cash. If paid in cash, the retainers will be paid in four equal quarterly installments in arrears. In addition to the annual retainers, our non-employee directors will each receive an annual grant of RSUs with a grant date value of $160,000 and such award will vest on the one-year anniversary of the date of grant, subject to the non-employee director’s continued service on our Board through the applicable vesting date. In addition, the non-executive Chairperson, if any, will receive additional RSUs with a grant date value (as determined by our Board) equal to approximately $75,000. Each director is fully indemnified by us for actions associated with being a director to the fullest extent permitted under Delaware law.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Policies and Procedures for Approval of Related Party Transactions

Under the Company’s Related Party Transactions Policy, our Audit Committee reviews and approves any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, with certain exceptions set forth in Item 404 of Regulation S-K under the Securities Act, in which the Company is or will be a participant, where the aggregate amount involved will or may be expected to exceed $120,000 in any fiscal year, and in which any Related Party has or will have a direct or indirect material interest (a “Related Party Transaction”). Related Party Transaction also includes any material amendment or modification to an existing Related Party Transaction. A “Related Party” means:

•any person who is or was since the beginning of the last fiscal year, even if such person does not presently serve in that role, an executive officer, director, or nominee for director of the Company;

•any shareholder that beneficially owns more than 5% of any class of the Company’s voting securities; or

•an Immediate Family Member of any such person.

In reviewing and approving Related Party Transactions, our Audit Committee is tasked to consider all relevant facts and circumstances, including, but not limited to, whether the transaction is on terms comparable to those that could be obtained in an arm’s length transaction and the extent of the Related Party’s interest in the transaction, whether the transaction will be undertaken in the ordinary course of business, and the purpose and the potential benefits to the Company of the proposed transaction.

Under the Related Party Transactions Policy, the following transactions are deemed to be automatically pre-approved and do not need to be brought to the Audit Committee for approval:

•any employment relationship or transactions involving an executive officer of the Company, as long as the executive officer is not an immediate family member of another executive officer, director or 5% owner of the Company, the related compensation is reported in the Company’s proxy statement, and the compensation paid to the executive officer was approved by the Compensation Committee;

•transactions involving the recovery of erroneously awarded compensation computed as provided by the rules of the SEC and NYSE listing standards that is reported in the Company’s proxy statement;

•transactions involving compensation and benefits paid to a director for service as a director of the Company if the compensation is reported in the Company’s proxy statement;

•transactions with another company in which the only relationship of a director or executive officer or immediate family member of a director or executive officer is as an employee (other than an executive officer), a director, or a beneficial owner of less than 10% (together with their immediate family members) of that company’s outstanding equity, provided that the aggregate amount involved does not exceed the greater of $1,000,000 or 2% of the other company’s annual revenues;

•transactions in which the interest of the Related Party arises solely from the ownership of a class of equity securities of the Company, and all holders of that class of equity securities receive the same benefit on a pro rata basis;

•transactions in which the rates or charges involved are determined by competitive bids;

•charitable contributions, grants, or endowments by the Company or the Company’s charitable foundation to a charitable organization, foundation or university at which a Related Party’s only relationship is as an employee (other than an executive officer) or a director, if the aggregate amount involved does not exceed the greater of $250,000 or 2% of the charitable organization’s annual receipts;

•transactions involving the rendering of services as a common or contract carrier or public utility at rates or charges fixed in conformity with law or governmental regulation; and

•transactions involving services as a bank depositary of funds, transfer agent, registrar, trustee under a trust indenture, or similar services.

Table of Contents

Annually, the Audit Committee reviews any previously approved related party transaction or arrangement that is continuing and determines based on then existing facts and circumstances whether it is in our best interest to continue, modify or terminate each such transaction or arrangement.

The Related Party Transactions Policy supplements the Conflicts of Interest provisions in our Code of Ethics.

Our Code of Ethics requires us to avoid, wherever possible, all conflicts of interests except as approved by the General Counsel of the Company or as disclosed in our public filings with the SEC. Under our Code of Ethics, conflict of interest situations include, among others, any financial transaction, arrangement or relationship (including any indebtedness or guarantee of indebtedness) involving the Company, and any circumstance, event, relationship or situation in which the personal interest of any of our directors, officers or employees interferes or appears to interfere with our interests as a whole. A copy of our Code of Ethics is available on our website at www.infinitynaturalresources.com. We intend to satisfy the disclosure requirement regarding any amendment to, or any waiver of, a provision of the Code of Ethics by posting such information on our website.

Although our management believes that the terms of the Related Party Transactions described below are reasonable, it is possible that we could have negotiated more favorable terms for such transactions with unrelated third parties.

Related Party Transactions

Funds affiliated with Pearl Energy Investments, L.P., NGP Energy Capital Management, L.L.C. and Quantum Capital Group each beneficially own, on an as-converted basis, more than 5% of the outstanding shares of Class A common stock of the Company. For the current ownership of each Related Person and its related affiliates in the Company, please see the “Security Ownership of Certain Beneficial Owners and Management” section below. Pearl also has two director representatives currently serving on the Board, and Carnelian has one director representative currently serving on the Board.

Because of their significant ownership in the Company and board representation, any otherwise qualifying transactions between the Company and investments affiliated with any of these Related Persons is considered a related person transaction under the Company’s Related Party Transaction Policy. The following list reflects the Company’s related party transactions for 2025 and the first quarter of 2026. We believe that the terms of these arrangements are no less favorable to either party than those held with unaffiliated parties.

INR Holdings LLC Agreement

Under the Second Amended and Restated Limited Liability Company Agreement of Infinity Natural Resources, LLC (“INR Holdings” and, such agreement, the “INR Holdings LLC Agreement”), we have the right to determine when distributions will be made to us and the holders (other than the Company) of INR Units and a corresponding number of shares of Class B common stock (collectively, the “INR Unit Holders”) and the amount of any such distributions. If we authorize a distribution, such distribution will be made to the INR Unit Holders and us on a pro rata basis in accordance with our respective percentage ownership of INR Units.

We and the INR Unit Holders will generally incur U.S. federal, state and local income taxes on our proportionate share of any taxable income of INR Holdings and will be allocated our proportionate share of any taxable loss of INR Holdings. Net profits and net losses of INR Holdings generally will be allocated to us and the INR Unit Holders on a pro rata basis in accordance with our respective percentage ownership of INR Units, except that certain non-pro rata adjustments will be required to be made to reflect built-in gains and losses and tax depreciation, depletion and amortization with respect to such built-in gains and losses. The INR Holdings LLC Agreement provides, to the extent cash is available, for pro rata tax distributions to us and the INR Unit Holders in an amount at least sufficient to allow us to pay our taxes and make payments under that certain Tax Receivable Agreement, dated as of January 30, 2025, by and among the Company and the Pearl, NGP, certain other co-investors and the management members that directly and indirectly own equity interests in INR Holdings or its wholly owned subsidiaries (the “Existing Owners” and, such agreement, the “Tax Receivable Agreement”). For the

Table of Contents

tax year ended December 31, 2025, INR Holdings did not make any payments to the Company or the INR Unit Holders pursuant to the Tax Receivable Agreement.

The INR Holdings LLC Agreement provides that, except as otherwise determined by us, at any time we issue a share of our Class A common stock or any other equity security (other than pursuant to an incentive plan, stockholders rights plan or to a member in connection with redemption of INR Units by such member), the net proceeds received by us with respect to such issuance, if any, shall be concurrently contributed to INR Holdings, and INR Holdings shall issue to us one INR Unit or other economically equivalent equity interest. Conversely, if at any time, any shares of our Class A common stock are redeemed, repurchased or otherwise acquired, INR Holdings shall redeem, repurchase or otherwise acquire an equal number of INR Units held by us, upon the same terms and for the same price, as such shares of our Class A common stock are redeemed, repurchased or otherwise acquired.

Under the INR Holdings LLC Agreement, the members have agreed that any member and/or its affiliates will be permitted to engage in business activities or invest in or acquire businesses which may compete with our business.

INR Holdings will be dissolved only upon the first to occur of (a) approval of its dissolution by the managing member and a vote in favor of dissolution by at least two-thirds of the holders of its INR Units, (b) a change of control transaction that is not approved by at least two-thirds of the holders of its INR Units, (c) such time as there are no remaining members of INR Holdings or (d) entry of a judicial order to dissolve INR Holdings. Upon dissolution, INR Holdings will be liquidated and the proceeds from any liquidation will be applied and distributed in the following manner (subject to establishing cash reserves for contingent liabilities): (i) first, to all expenses incurred in liquidation, (ii) second, to creditors in satisfaction of all debts, liabilities and obligations of INR Holdings and (iii) third, to the members in proportion to the number of INR Units owned by each of them.

Tax Receivable Agreement

We are party to the Tax Receivable Agreement. This agreement generally provides for the payment by the Company to the Existing Owners of 85% of the net cash savings, if any, in U.S. federal, state and local income tax that the Company (a) actually realizes with respect to taxable periods ending after this offering or (b) is deemed to realize in the event of a change of control (as defined under the Tax Receivable Agreement, which includes certain mergers, asset sales and other forms of business combinations and certain changes to the composition of the Board) or the Tax Receivable Agreement terminates early (at our election or as a result of our breach) with respect to any taxable periods ending on or after such change of control or early termination event, in each case, as a result of (i) the tax basis increases resulting from the exchange of INR Units and the corresponding surrender of an equivalent number of shares of Class B common stock by the Existing Owners for a number of shares of Class A common stock on a one-for-one basis or, at our option, the receipt of an equivalent amount of cash pursuant to the INR Holdings LLC Agreement and (ii) deductions arising from imputed interest deemed to be paid by us as a result of, and additional tax basis arising from, any payments we make under the Tax Receivable Agreement. INR will retain the benefit of the remaining 15% of these cash savings, if any. If we experience a change of control or the Tax Receivable Agreement terminates early, we could be required to make substantial, immediate lump-sum payments to the Existing Owners.

Certain Relationships

Issuance of Series A Preferred Stock

Securities Purchase Agreement

On February 18, 2026, the Company entered into a Securities Purchase Agreement with the Preferred Purchasers, pursuant to which, on February 23, 2026 (the “Initial Issue Date”), the Company issued and sold 350,000 shares of newly designated Series A Preferred Stock at a price of $1,000 per share (the “Initial Liquidation Preference”) for an aggregate purchase price of $350 million (the “Preferred Investment”). Quantum acquired 275,000 shares of Series A Preferred Stock, and Carnelian acquired 75,000 shares of Series A Preferred Stock. The

Table of Contents

Securities Purchase Agreement contains customary representations, warranties and covenants of the Company and the Preferred Purchasers.

In connection with the Preferred Investment, we agreed to provide the Preferred Purchasers with certain customary registration rights, including rights with respect to the filing of a shelf registration statement, underwritten offering rights and piggyback rights with respect to any shares of Class A common stock of the Company issuable upon conversion of the Series A Preferred Stock.

Certificate of Designation

Each share of Series A Preferred Stock has the powers, designations, preferences, and other rights of the shares of such series as are set forth in the Certificate of Designation of the Series A Preferred Stock filed by the Company with the Secretary of State of the State of Delaware on February 23, 2026 (the “Certificate of Designation”).

Dividends

Holders of Series A Preferred Stock are entitled to dividends (i) at the rate of 8% per annum until but excluding the five year anniversary of the Preferred Closing, and (ii) at the rate of 12% per annum on and after the five year anniversary of the Preferred Closing. Holders of Series A Preferred Stock will also be entitled to participate in any dividends or other distributions declared or paid in cash on the shares of Class A common stock, on an as-converted basis. Dividends are payable quarterly in arrears, and dividends accrued through and including the second anniversary of the Preferred Closing may be paid, at the Company’s option, in cash or by increasing the Initial Liquidation Preference of each share of Series A Preferred Stock by the amount of the applicable dividend. After the second anniversary of the Preferred Closing, dividends must be paid in cash; however, to the extent the Company is restricted from paying dividends in cash, dividends will accrue as an increase to the Initial Liquidation Preference and will incur a 2% per annum increase to the regular dividend rate then in effect. In each case, the Company’s ability to pay cash dividends is subject to the restrictions under that certain Credit Agreement, dated as of September 25, 2024, by and among INR Holdings, the lenders from time to time party thereto and Citibank, N.A., as the administrative agent, collateral agent and an issuing bank.

Liquidation Preference

The Series A Preferred Stock ranks senior to the Class A common stock with respect to distribution rights and rights upon liquidation, dissolution or winding up of the Company (“Liquidation”), on parity with any class or series of capital stock of the Company expressly designated as ranking on parity with the Series A Preferred Stock with respect to distribution rights and rights upon Liquidation, junior to any class or series of capital stock of the Company expressly designated as ranking junior to the Series A Preferred Stock with respect to distribution rights and rights upon Liquidation and junior in right of payment to the Company’s existing and future indebtedness. Upon a Liquidation, each share of Series A Preferred Stock is entitled to receive an amount equal to the greater of (i) a liquidation preference equal to the greater of (A) an internal rate of return of 13% per annum on the Initial Liquidation Preference or (B) a 1.3x return on the Initial Liquidation Preference and (ii) the amount such holder would have received in respect of the number of shares of Class A common stock that would be issuable upon conversion of such share of Series A Preferred Stock. The Regular Dividend for the quarter ended March 31, 2026, accrued as an increase to the Initial Liquidation Preference on the Series A Preferred Stock.

Conversion Rights

Each holder of Series A Preferred Stock has the right, at its option, to convert its Series A Preferred Stock, in whole or in part, into fully paid and non-assessable shares of Class A common stock at a conversion price equal to $21.39 per share, subject to certain customary adjustments.

Additionally, until the approval of the Stock Issuance Proposal or a similar stockholder proposal, the aggregate number of shares of Class A common stock issuable or deliverable upon conversion of any Series A Preferred Stock (subject to proportionate adjustment for stock dividends, stock splits or stock combinations with

Table of Contents

respect to the Class A common stock) is capped at 19.9% of the shares of common stock issued and outstanding immediately prior to the issuance of the Series A Preferred Stock.

Finally, the Company has the right beginning three years after the issuance of the Series A Preferred Stock to convert any shares of Series A Preferred Stock into fully paid and non-assessable shares of Class A common stock if the last reported sales price of its Class A common stock for any 20 of the last 30 trading days exceeds 140% of the conversion price.

Redemption and Repurchase Rights

The Company may, at its option, redeem all or any of the Series A Preferred Stock for cash at any time beginning five years after the issuance of the Series A Preferred Stock at a price resulting in the holders of Series A Preferred Stock achieving an internal rate of return of 15% per annum on the Initial Liquidation Preference. Upon a change of control of the Company, any share of Series A Preferred Stock to be repurchased would be entitled to receive an amount in cash equal to the greater of (i) an internal rate of return of 13% per annum on the Initial Liquidation Preference or (ii) a 1.3x return on the Initial Liquidation Preference.

Voting and Consent Rights

Holders of Series A Preferred Stock generally are entitled to vote with the holders of the shares of Class A common stock on all matters submitted for a vote of holders of shares of Class A common stock (voting together with the holders of shares of Class A common stock as one class) on an as-converted basis. Prior to approval of the Stock Issuance Proposal or a similar stockholder proposal, the Preferred Purchasers’ voting power with respect to the Series A Preferred Stock is capped at 19.9% of the shares of common stock issued and outstanding immediately prior to the issuance of the Series A Preferred Stock.

Director Appointment Right

In connection with the Preferred Investment, Carnelian is entitled to appoint one individual to the Board. Carnelian will have the exclusive right to appoint and elect one director to the Board for so long as Carnelian (i) owns, of record or beneficially, all of the shares of Series A Preferred Stock issued to Carnelian at the Preferred Closing and (ii) holds of record and beneficially owns (within the meaning of Rule 13d-3 under the Exchange Act) more than 3% of the outstanding shares of Class A common stock and the Class B common stock, par value $0.01 per share, of the Company, on a fully diluted basis, including the shares of Class A common stock issuable upon conversion of shares of Series A Preferred Stock.

In connection with the Preferred Investment and pursuant to the Certificate of Designation, Carnelian nominated Matthew Kelly to serve on the Board, and Mr. Kelly was appointed to the Board effective February 23, 2026.

For so long as holders of outstanding shares of Series A Preferred Stock have the right to appoint the Series A Director, the shares of Series A Preferred Stock held by Carnelian will be the only shares of Series A Preferred Stock entitled to vote on or consent to the removal without cause of the Series A Director, and the shares of Series A Preferred Stock owned by any other holders as of the record date for determining stockholders entitled to vote thereon will have no voting rights with respect to such matter. In the event that a vacancy is created on the Board at any time due to the death, disability, retirement, resignation, or removal of the Series A Director, then Carnelian, voting on behalf of the holders of outstanding shares of Series A Preferred Stock entitled to vote thereon, voting separately as a single class, shall have the exclusive right to appoint an individual to fill such vacancy, and the shares

Table of Contents

of Series A Preferred Stock owned by any other holders as of the record date for determining stockholders entitled to vote thereon shall have no voting rights with respect to such matter; provided that the replacement appointee will be an employee of Carnelian and subject to the approval of the Board. In the event that Carnelian shall fail to appoint in writing a representative to fill the vacant Series A Director seat on the Board, and such Board seat shall remain vacant until such time as Carnelian elects an individual to fill such seat in accordance with the Certificate of Designation, and during any period where such seat remains vacant, the Board nonetheless shall be deemed duly constituted. Carnelian’s right to appoint the Series A Director is non-transferable.

As a condition to Carnelian’s right to appoint a Series A Director, the Series A Director appointee shall submit to the Board an irrevocable resignation letter stating that the Series A Director resigns upon the lapsing of the right to appoint a Series A Director contained in the Certificate of Designation (the “Resignation Letter”), which the Board shall have the right to accept or reject upon such future date. Notwithstanding the foregoing, at the time when Carnelian ceases to be entitled to appoint and elect a Series A Director pursuant to the terms of the Certificate of Designation, the right of Carnelian to appoint and elect a Series A Director shall permanently terminate and from and after such time and, subject to acceptance of the Resignation Letter by the Board, the Series A Director shall cease to be qualified to serve as a director, such directorship shall terminate and the size of the Board shall automatically be reduced (unless the Board, in its sole discretion, elects to fill such vacancy with another director).

PROPOSAL 2: APPROVAL ON A NON-BINDING ADVISORY BASIS OF OUR NAMED EXECUTIVE OFFICER COMPENSATION

In accordance with the Dodd-Frank Act of 2010 (the “Dodd-Frank Act”) and Section 14A of the Exchange Act, we are asking our stockholders to vote to approve, on a non-binding, advisory basis, the compensation of our Named Executive Officers as disclosed in this Proxy Statement.

As described in detail under the heading “Executive Compensation,” our executive compensation programs are designed to attract, motivate and retain our Named Executive Officers, who are critical to our success. Please read “Executive Compensation” and the accompanying tables and narrative disclosure for details about our executive compensation programs. We are asking our stockholders to indicate their support for our Named Executive Officer compensation as described in this Proxy Statement. This proposal, commonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to express their views on our Named Executive Officers’ compensation. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our Named Executive Officers and the philosophy, policies and practices described in this Proxy Statement. Accordingly, we will ask our stockholders to vote “FOR” the following resolution at the Annual Meeting:

“RESOLVED, that the stockholders of Infinity Natural Resources, Inc. (the “Company”) approve, by a non-binding advisory vote, the compensation of the Named Executive Officers for 2026, as disclosed in the Company’s Proxy Statement for the 2026 Annual Meeting pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Executive Compensation, the 2025 Summary Compensation Table and the other related tables and disclosure.”

The say-on-pay vote is advisory, and therefore not binding on our company, our Board or the Compensation Committee. However, our Board and the Compensation Committee value the opinions of our stockholders and intend to consider our stockholders’ views regarding our executive compensation programs, including in making future decisions relating to such programs.

Vote Required and Board Recommendation

The approval by a non-binding advisory vote of our Named Executive Officer compensation requires the vote of a majority of the votes cast by the stockholders present or represented by proxy at the Annual Meeting and entitled to vote on this proposal. Abstentions will not be counted as a vote cast and, therefore, will not have an effect on the outcome of the vote. Broker non-votes have no effect on the outcome of the vote.

Our Board unanimously recommends that you vote “FOR” the approval of the compensation of our Named Executive Officers as disclosed in this Proxy Statement pursuant to the compensation disclosure rules of the SEC.

Table of Contents

PROPOSAL 3: RECOMMENDATION ON A NON-BINDING ADVISORY BASIS THE FREQUENCY OF FUTURE ADVISORY VOTES TO APPROVE OUR NAMED EXECUTIVE OFFICER COMPENSATION

The Dodd-Frank Act also enables our stockholders to indicate, on a non-binding, advisory basis, how frequently we should seek an advisory vote to approve the compensation of our Named Executive Officers, such as the Say-On-Pay Proposal included in this Proxy Statement. By voting on this Say-On-Frequency Proposal, stockholders may indicate whether they would prefer future advisory votes to approve Named Executive Officer compensation every one year, every other year or every three years, or stockholders may abstain from voting.

After careful consideration of this Say-On-Frequency Proposal, the Board has determined that an advisory vote to approve our Named Executive Officer compensation that occurs every one year is the most appropriate alternative for the Company, and therefore the Board recommends that you vote for “every one year” as the frequency of future advisory votes to approve our Named Executive Officer compensation.

In formulating its recommendation, the Board considered that an annual advisory vote to approve our Named Executive Officer compensation will allow our stockholders to provide us with their direct input on our compensation philosophy, policies and practices as disclosed in the proxy statement every one year, which is consistent with our efforts to engage in an ongoing dialogue with our stockholders on executive compensation and corporate governance matters. We understand that our stockholders may have different views as to what is the best approach for the Company, and we look forward to hearing from our stockholders on this Say-On-Frequency Proposal.

You may cast your vote on your preferred voting frequency by choosing the option of every one year, every other year or every three years or abstain from voting. However, because this vote is advisory and not binding on the Company or the Board, the Board may decide that it is in the best interests of the Company to hold an advisory vote to approve our Named Executive Officer compensation more or less frequently than the option approved by our stockholders.

Vote Required and Board Recommendation

The option of every one year, every other year or every three years that receives a majority of the votes cast by shares that are present in person or represented by proxy at the Annual Meeting and entitled to vote on such matter at the Annual Meeting will be considered the frequency selected by the stockholders. In the event that no option receives such majority, we will consider the option that receives the most votes to be the option selected by the stockholders.

Our Board unanimously recommends that you vote for “EVERY ONE YEAR” as the frequency for future advisory votes to approve the compensation of our Named Executive Officers.

PROPOSAL 4: RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Deloitte & Touche LLP, which has been our independent audit firm since 2023, has been appointed by our Audit Committee as our independent auditors for the fiscal year ending December 31, 2026, and our Audit Committee has further directed that the appointment of Deloitte & Touche LLP be submitted for ratification by our stockholders at the Annual Meeting. We have been advised by Deloitte & Touche LLP that neither that firm nor any of its associates has any relationship with us or our subsidiaries other than the usual relationship that exists between independent auditors and their clients. Representatives of Deloitte & Touche LLP are expected to be present at the Annual Meeting and will be provided an opportunity to make a statement and to respond to appropriate inquiries from stockholders.

Stockholder ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm is not required by our Amended and Restated Bylaws (as amended, the “Bylaws”), Corporate Governance Guidelines, committee charters or otherwise. However, the Board is submitting the appointment of Deloitte & Touche LLP to our stockholders for ratification as a matter of what it considers to be good corporate practice. Even if the appointment is ratified, our Audit Committee, in its discretion, may appoint a different independent accounting firm at any time during the year if our Audit Committee determines that such a change would be in our and our stockholders’ best interests.

Principal Accounting Firm Fees

The table below sets forth the aggregate fees billed by Deloitte & Touche LLP, the Company’s independent registered public accounting firm, for the last two fiscal years.


Auditor Fees(1)	2024	2025
Audit Fees	$2,642,219	$1,486,704
Audit-Related Fees	—	77,000
Tax Fees	33,425	785,616
All Other Fees	2,674	—
Total	$2,678,318	$2,349,320

____________________________________

(1)Audit Fees. This category consists of the annual audit of our consolidated financial statements and the interim reviews of the quarterly consolidated financial statements and services rendered in connection with registration statements, including comfort letters and consents.

Audit-Related Fees. This category consists of fees billed for professional services provided in connection with assurance and related services that are reasonably related to the performance of the audit or review of our financial statements and that are not reported under Audit Fees.

Tax Fees. This category includes all fees associated with tax compliance, tax advice, and tax planning work.

All Other Fees. This category consists of fees for all other services that are not reported above.

Audit Committee Approval

Consistent with requirements of the SEC and the Public Company Accounting Oversight Board (the “PCAOB”) regarding auditor independence, our Audit Committee is responsible for the appointment, compensation and oversight of the work of our independent registered public accounting firm. In recognition of this responsibility, our Audit Committee intends to establish a policy for the pre-approval of all audit and permissible non-audit services provided by the independent registered public accounting firm. These services may include audit services, audit-related services, tax services and other services.

Table of Contents

We did not have an Audit Committee in 2023 or 2024. In connection with the consummation of the IPO, our Board approved the provision of certain audit services by Deloitte & Touche LLP and concluded that such services were compatible with the maintenance of that firm’s independence in the conduct of its auditing functions, which services were ratified by the Audit Committee.

On an annual basis, the Audit Committee reviews and pre-approves the Company engaging the independent registered public accounting firm for the following year. As part of this process, the Audit Committee pre-approves all audit and permitted audit-related and non-audit services to be performed by the independent registered public accounting firm, including the fees relating thereto. The Audit Committee may delegate pre-approval authority to one or more of its members. In the event of any such delegation, any pre-approved decisions will be reported to the Audit Committee at its next scheduled meeting. All fees described in the table above were pre-approved by the Audit Committee.

Vote Required and Board Recommendation

Assuming a quorum is present, the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026 requires the affirmative vote of the holders of a majority of the voting power of the shares of stock present in person or represented by proxy at the Annual Meeting and entitled to vote on this proposal. Abstentions will have the same effect as a vote against this proposal. NYSE rules permit brokers to vote uninstructed shares at their discretion on this proposal, so broker non-votes are not expected.

Our Board unanimously recommends that you vote “FOR” the ratification of Deloitte & Touche LLP as our independent registered public accounting firm.

PROPOSAL 5: ISSUANCE OF CLASS A COMMON STOCK

General

Under Section 312.03 of the NYSE Listed Company Manual, stockholder approval is required prior to the issuance of shares of common stock, or of securities convertible into or exercisable for common stock, in certain circumstances, including if the number of shares of common stock to be issued is, or will upon issuance be, equal to or in excess of 20% of the number of shares of common stock outstanding before the issuance of the common stock or of securities convertible into or exercisable for common stock.

Pursuant to the Securities Purchase Agreement (as defined below), the Company issued an aggregate of 350,000 shares of Series A Preferred Stock. The Series A Preferred Stock, pursuant to the terms set forth in the Certificate of Designation (as defined below) and subject to approval by the Company’s stockholders of the Stock Issuance Proposal, is convertible into shares of Class A common stock. As of the Record Date and without giving effect to the Conversion Limitation, the shares of Series A Preferred Stock issued and outstanding were convertible into 16,493,688 shares of Class A common stock. In certain circumstances, the total aggregate number of shares of Class A common stock issuable upon the conversion of the Series A Preferred Stock may be increased in accordance with the terms of the Certificate of Designation. For example, dividends accrued through and including the second anniversary of the Initial Issue Date of the Series A Preferred Stock may be paid, at the Company’s option, in kind by increasing the Initial Liquidation Preference of each share of Series A Preferred Stock by the amount of the applicable dividend.

The Company is asking stockholders to approve, for purposes of Section 312.03 of the NYSE Listed Company Manual, the issuance of shares of Class A common stock upon the conversion of, or otherwise issued pursuant to the Securities Purchase Agreement, the shares of Series A Preferred Stock pursuant to the terms in the Certificate of Designation.

Background

On February 18, 2026, the Company entered into the Securities Purchase Agreement with affiliates of Quantum and Carnelian, to issue and sell at the Preferred Closing (as defined below) 350,000 shares of Series A Preferred Stock, at a price of $1,000 per share for an aggregate purchase price of $350 million. The Series A Preferred Stock is subject to the terms and conditions set forth in the Certificate of Designation.

Pursuant to the Certificate of Designation, each holder of Series A Preferred Stock has the right, at its option, to convert its Series A Preferred Stock, in whole or in part, into fully paid and non-assessable shares of Class A common stock at a conversion price equal to $21.39 per share, subject to certain customary adjustments. Additionally, until receipt of the stockholder approvals contemplated by Section 312.03 of the NYSE Listed Company Manual with respect to the issuance of shares of Class A common stock upon conversion of the Series A Preferred Stock in excess of the limitations imposed by such rules, the aggregate number of shares of Class A common stock issuable or deliverable upon conversion of any Series A Preferred Stock (subject to proportionate adjustment for stock dividends, stock splits or stock combinations with respect to the Class A common stock) is capped at 12,619,321 shares, or 19.9% of the shares of common stock issued and outstanding immediately prior to the issuance of the Series A Preferred Stock.

NYSE Stockholder Approval Requirement

The Class A common stock into which the Series A Preferred Stock will convert is listed on the NYSE, and, as such, the Company is subject to the rules set forth in the NYSE Listed Company Manual, including Section 312.03. In order to comply with the NYSE Listed Company Manual and to satisfy conditions under the Securities Purchase Agreement, the Company is seeking stockholder approval of the Stock Issuance Proposal. Section 312.03(c) of the NYSE Listed Company Manual requires stockholder approval prior to the issuance of common stock, or of securities convertible into or exercisable for common stock, in any transaction or series of related transactions if: (1) the common stock has, or will have upon issuance, voting power equal to or in excess of 20 percent of the voting power outstanding before the issuance of such stock or of securities convertible into or exercisable for common stock; or (2) the number of shares of common stock to be issued is, or will be upon issuance, equal to or in excess of 20 percent of the number of shares of common stock outstanding before the

Table of Contents

issuance of the common stock or of securities convertible into or exercisable for common stock. In addition, Section 312.03(d) of the NYSE Listed Company Manual requires stockholder approval prior to an issuance that will result in a change of control of the issuer.

In accordance with the requirements of Section 312.03 of the NYSE Listed Company Manual, and pursuant to the terms of the Securities Purchase Agreement and the Certificate of Designation, the Company is seeking the approval of its stockholders for the issuance of shares of Class A common stock issuable upon the conversion of the Series A Preferred Stock, which may be converted at Quantum’s or Carnelian’s option into shares of Class A common stock. Because the issuance of Class A common stock upon conversion of the Series A Preferred Stock would implicate Section 312.03(c) and could implicate Section 312.03(d) given NYSE rules do not define "change of control," we are seeking stockholder approval prior to making such issuance.

Effect on Current Stockholders

If the Stock Issuance Proposal is adopted, the shares of Series A Preferred Stock outstanding would initially be convertible into 16,493,688 shares of Class A common stock as of the Record Date, which number may be increased in certain circumstances in accordance with the terms of the Certificate of Designation. The issuance of such shares would result in significant dilution to our stockholders who are not the holders of Series A Preferred Stock and would afford our stockholders a smaller percentage interest in the voting power, liquidation value, and aggregate book value of the Company. This means that our current stockholders who are not party to the Securities Purchase Agreement will own a smaller interest in us as a result of the conversion and therefore have less ability to influence significant corporate decisions requiring stockholder approval. Issuance of shares of Class A common stock upon conversion of the Series A Preferred Stock will also have a dilutive effect on book value per share and any future earnings per share. Dilution of equity interests could also cause prevailing market prices for our Class A common stock to decline.

Description of Series A Preferred Stock

For a description of the Series A Preferred Stock, including the rights of the Preferred Purchasers, see the section of this proxy statement titled “Certain Relationships and Related Party Transactions—Certain Relationships—Issuance of Series A Preferred Stock” and the Current Report on Form 8-K we filed with the SEC on February 23, 2026.

Consequences of Failing to Obtain Stockholder Approval

Under the terms of the Securities Purchase Agreement, we are required to include a proposal to approve the issuance of all of the shares of Class A common stock issuable upon conversion of the shares of Series A Preferred Stock. If our stockholders do not approve the Stock Issuance Proposal at the Annual Meeting, then we will continue to seek the approval of the Stock Issuance Proposal by our stockholders at least bi-annually until such approval is obtained.

Interest of Certain Persons in Matters to be Acted Upon

No director, executive officer, associate of any director or executive officer or any other person has any substantial interest, direct or indirect, by security holdings or otherwise, in the Stock Issuance Proposal that is not shared by our stockholders.

Vote Required and Board Recommendation

Assuming a quorum is present, the affirmative vote of a majority of the votes cast at the Annual Meeting will be required to approve this proposal. For purposes of this proposal, “votes cast” means votes cast “FOR” or “AGAINST” the proposal and excludes abstentions and broker non-votes. Because abstentions and broker non-votes are not considered votes cast, they will have no effect on the outcome of this proposal. Under the rules of the NYSE, this proposal is considered a “non-routine” matter, which means that brokers, banks, and other nominees who hold shares in “street name” on behalf of beneficial owners do not have discretionary authority to vote on this proposal without receiving voting instructions from the beneficial owner. Accordingly, if you are a beneficial owner and do

Table of Contents

not provide voting instructions to your broker, bank, or other nominee, your shares will not be voted on this proposal and will be treated as a “broker non-vote.”

Our Board unanimously recommends that you vote “FOR” the Stock Issuance Proposal.

Our management does not know of any other matters to come before the Annual Meeting, and our Board does not intend to present any other items of business other than those stated in the Notice of 2026 Annual Meeting of Stockholders. If, however, any other matters do come before the Annual Meeting, it is the intention of the persons designated as proxies to vote in accordance with their discretion on such matters.

QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING

In this section of the Proxy Statement, we answer some common questions regarding the Annual Meeting and the voting of shares of common stock and, on an as converted basis, Series A Preferred Stock at the Annual Meeting.

When and where will the Annual Meeting be held?

The Annual Meeting will be a virtual meeting, conducted exclusively via live webcast. There will not be a physical location for the Annual Meeting, and you will not be able to attend the Annual Meeting in person.

You will be able to attend the Annual Meeting online and submit your questions during the Annual Meeting by visiting www.virtualshareholdermeeting.com/INR2026. To participate in the Annual Meeting, you will need the 16-digit control number included on your Notice of Internet Availability, on your proxy card, or on the instructions that accompanied your proxy materials.

Stockholders will have the same rights and opportunities to participate in our virtual Annual Meeting as they would at an in-person meeting.

The virtual Annual Meeting platform is fully supported across browsers (Internet Explorer, Firefox, Chrome and Safari) and devices (desktops, laptops, tablets and cell phones) running the most updated version of applicable software and plugins. Participants should ensure that they have a strong WiFi connection wherever they intend to participate in the Annual Meeting.

The Annual Meeting webcast will begin promptly at 9:30 a.m. Eastern Time. We encourage you to access the Annual Meeting webcast prior to the start time. Online access to the Annual Meeting will open at 9:15 a.m. Eastern Time.

What if during the check-in time or during the Annual Meeting I have technical difficulties or trouble accessing the virtual Annual Meeting website?

If you encounter any technical difficulties with the virtual Annual Meeting website on the Annual Meeting day, please call the technical support number that will be posted on the virtual Annual Meeting log in page. Technical support will be available starting at 9:15 a.m. Eastern Time on June 9, 2026 and until the Annual Meeting has finished.

How do I submit a question at the Annual Meeting?

Stockholders will be able to submit questions live during the virtual Annual Meeting by following the on-screen instructions. We will answer questions relevant to meeting matters and that otherwise comply with the Annual Meeting rules of conduct. Questions regarding personal matters or matters not relevant to the Annual Meeting will not be answered.

Why did I receive a Notice Regarding the Internet Availability of Proxy Materials for the Annual Meeting in the mail instead of a paper copy of the proxy materials?

The SEC has approved rules allowing companies to furnish proxy materials, including this Proxy Statement and our Annual Report, to our stockholders by providing access to such documents on the internet instead of mailing paper copies. We believe these rules provide a convenient and quick way in which our stockholders can access the proxy materials and vote their shares, while allowing us to conserve natural resources and reduce the costs of printing and distributing the proxy materials.

Accordingly, certain of our stockholders will receive a Notice and will not receive paper copies of the proxy materials unless they request them. Instead, the Notice will provide such stockholders with notice of the Annual Meeting and will also provide instructions regarding how such stockholders can access and review all the proxy materials on the internet. The Notice also provides instructions as to how you may submit your proxy

Table of Contents

electronically via the internet or by telephone. If you received the Notice and you would instead prefer to receive a paper or electronic copy of the proxy materials, you should follow the instructions for requesting such materials that are provided in the Notice. Any request to receive proxy materials by mail or email will remain in effect until you revoke it.

Why did you send me the proxy materials or the Notice?

We sent you the proxy materials or the Notice because we are holding our Annual Meeting and our Board is asking for your proxy to vote your shares at the Annual Meeting. We have summarized information in this Proxy Statement that you should consider in deciding how to vote at the Annual Meeting.

Can I vote my shares by filling out and returning the Notice?

No. The Notice identifies the items to be voted on at the Annual Meeting, but you cannot vote by marking the Notice and returning it. The Notice provides instructions on how to authorize your proxy electronically via the internet, by telephone or by requesting and returning a paper Proxy Card, or you may vote your shares by submitting an electronic ballot during the Annual Meeting.

Who can vote?

You are entitled to vote your shares if our records show that you were the owner of shares of our common stock or Series A Preferred Stock as of the close of business on April 13, 2026, the record date for determining the stockholders who are entitled to vote at the Annual Meeting. As of April 13, 2026, there were a total of 18,751,177 shares of Class A common stock, 44,780,230 shares of Class B common stock issued and, subject to the Conversion Limitation, 350,000 shares of Series A Preferred Stock entitled to vote at the Annual Meeting. You get one vote for each share of common stock that you own. Each record holder of Series A Preferred Stock will have a number of votes equal to the largest number of whole shares of Class A common stock into which such shares are convertible on the Record Date (subject to the Conversion Limitation) on each matter that is properly brought before the Annual Meeting and on which holders of Series A Preferred Stock are entitled to vote together with common stock as a single class. As of the Record Date, there were 350,000 shares of Series A Preferred Stock outstanding, which, as of such date, were convertible into 16,493,688 shares of Class A common stock, of which 12,619,321 shares are eligible to be voted pursuant to the Conversion Limitation.

How is a quorum determined?

The holders of record of a majority of the voting power of the issued and outstanding shares of our capital stock entitled to vote at the Annual Meeting must be present in person or represented by proxy to constitute a quorum for the Annual Meeting. Abstentions are counted as present and entitled to vote for purposes of determining a quorum. Broker non-votes will also be considered present for the purpose of determining whether we have a quorum. Virtual attendance at the Annual Meeting constitutes presence in person for purposes of a quorum. If you authorize your proxy online or telephonically or sign and return your Proxy Card, your shares will be counted to determine whether we have a quorum even if you abstain or fail to indicate your vote on the Proxy Card.

What is the required vote for approval?

Directors will be elected at the Annual Meeting by a plurality of the votes cast in respect of the shares present in person or represented by proxy and entitled to vote on the election of directors, which means that the director nominees with the greatest number of votes cast, even if less than a majority, will be elected (with holders of our common stock and holders of Series A Preferred Stock voting together as a single class). Votes withheld and broker non-votes will have no effect on the voting results for the election of directors. There is no cumulative voting. See “Corporate Governance—Plurality Voting in Director Elections” for additional information regarding the plurality voting standard.

The recommendation on the frequency of future advisory votes to approve our Named Executive Officer compensation (every one year, every other year, or every three years) that receives the greatest number of votes cast by the stockholders present or represented by proxy at the Annual Meeting and entitled to vote on the proposal (with

Table of Contents

holders of our common stock and holders of Series A Preferred Stock voting together as a single class) will be considered the frequency recommended by the stockholders. Abstentions and broker non-votes will not be counted as votes cast and, therefore, will not have an effect on the results of the recommendation.

The approval of the Say-On-Pay Proposal, the Auditor Ratification Proposal and the Stock Issuance Proposal each require the vote of a majority of the votes cast by the stockholders present or represented by proxy at the Annual Meeting and entitled to vote on the proposal (with holders of our common stock and holders of Series A Preferred Stock voting together as a single class). If you abstain for purposes of these proposals, your abstention will not be counted as a vote cast and, therefore, will not have an effect on the results of such vote. Broker non-votes will have no effect on the outcome of the Say-On-Pay Proposal or the Stock Issuance Proposal. The rules of the NYSE permit brokers to vote uninstructed shares at their discretion regarding the Auditor Ratification Proposal, so we do not expect any broker non-votes on this proposal.

Why are holders of our capital stock being asked to vote on the election of only eight director nominees?

Our Board currently consists of ten members. A total of eight director nominees will be voted upon at the Annual Meeting. Holders of our common stock and holders of our Series A Preferred Stock, voting together as a single class, are being asked to vote on each of the eight director nominees. Mr. Sproule will serve on the Board through the end of his current term on date of the Annual Meeting but was not nominated for re-election. The right to appoint the Series A Director is held exclusively by Carnelian. See the section of this Proxy Statement titled “Certain Relationships and Related Party Transactions—Certain Relationships—Issuance of Series A Preferred Stock —Certificate of Designation— Director Appointment Right” for more information.

Why do holders of Series A Preferred Stock have voting and consent rights that differ from those of the holders of common stock?

The central voting rights of our Series A Preferred Stock generally adhere to the one-share, one-vote principle (based on the number of shares of Class A common stock issuable upon a conversion of our Series A Preferred Stock (subject to the Conversion Limitation)). On matters where holders of common stock and Series A Preferred Stock vote together as a single class, each holder of the Series A Preferred Stock is entitled to a number of votes that is equivalent to the number of shares of Class A common stock issuable upon a conversion of that holder’s Series A Preferred Stock. The Series A Preferred Stock does not have disproportionate voting power as compared to the common stock on matters where it votes as a single class with the common stock. There are no “high-vote” mechanisms that entitle the holders of Series A Preferred Stock to cast votes on these matters in excess of the number of shares of Class A common stock issuable upon a conversion of the Series A Preferred Stock. As is not uncommon for preferred stock investors, Carnelian, through its affiliates (as the holders of our Series A Preferred Stock), have the right to appoint one director to our Board, subject to a fall-away concept described below.

Additionally, subject to certain exceptions and ownership thresholds, the consent of the holders of Series A Preferred Stock holding a majority of the then outstanding shares of Series A Preferred Stock is required for, among other things, certain amendments to the Company’s organizational documents, issuances of senior or parity securities, payment of dividends, delisting from the NYSE or deregistration from Section 12 of the Exchange Act, formation of non-wholly owned subsidiaries, the incurrence of debt up to a certain threshold and any deviation from certain enumerated hedging requirements. As a general matter, the Preferred Purchasers must hold at least 60,000 shares of Series A Preferred Stock to maintain the consent rights listed above and certain consent rights held by the Series A Preferred Stock will terminate automatically when less than 100,000 shares of Series Preferred Stock remain outstanding in the aggregate.

The voting rights of the Series A Preferred Stock are subject to qualifications. Carnelian’s director appointment right is non-transferrable. In connection with the Preferred Investment, Carnelian is entitled to the exclusive right, subject to the approval of the Board, to appoint and elect one director to the Board for so long as Carnelian (i) owns, of record or beneficially, all of the shares of Series A Preferred Stock issued to Carnelian on the initial issue date of the Preferred Investment and (ii) holds of record and beneficially owns (within the meaning of Rule 13d-3 under the Exchange Act) more than 3% of the outstanding shares of Class A common stock and the Class B common stock on a fully diluted basis, including the shares of Class A common stock issuable upon

Table of Contents

conversion of shares of Series A Preferred Stock. In connection with the Preferred Investment, and pursuant to the Certificate of Designation, Carnelian designated Matthew Kelly to serve on the Board, and Mr. Kelly was appointed to the Board effective February 23, 2026. For a description of the Series A Preferred Stock, including additional information about Carnelian’s director appointment right, see the section of this proxy statement titled “Certain Relationships and Related Party Transactions—Certain Relationships—Issuance of Series A Preferred Stock.”

If Carnelian ceases to own, of record or beneficially, (i) all of the shares of Series A Preferred Stock issued to it on the initial issue date of the Preferred Investment or (ii) 3% or more of the outstanding shares of Class A common stock and the Class B common stock on a fully diluted basis, including the shares of Class A common stock issuable upon conversion of shares of Series A Preferred Stock, its right to appoint the Series A Director falls away.

Moreover, we will have the right to redeem all or a portion of the Series A Preferred Stock at our election on or after February 23, 2031. Given that the right of the Series A Preferred Stock to appoint one director to our Board is limited to Carnelian and the fall away provisions for both the director appointment right and consent rights described above, we believe that the voting and consent rights of the Series A Preferred Stock do not inappropriately favor the holders of our Series A Preferred Stock.

How do I vote by proxy?

Follow the instructions on the Notice or the Proxy Card to authorize a proxy to vote your shares at the Annual Meeting electronically via the internet or by telephone or, if you received paper proxy materials, by completing and returning the Proxy Card. The individuals named and designated as proxies will vote your shares as you instruct. You have the following choices in voting your shares:

•You may vote on each proposal, in which case your shares will be voted in accordance with your choices.

•In voting on the election of director nominees, you may either vote “FOR ALL,” “WITHHOLD ALL” or “FOR ALL EXCEPT” with respect to each nominee.

•You may abstain from voting on the Say-On-Pay Proposal, the Say-On-Frequency Proposal, the Auditor Ratification Proposal and the Stock Issuance Proposal.

You may return a signed Proxy Card without indicating your vote on any matter, in which case the designated proxies will vote to (1) elect the eight director nominees, (2) approve, on an advisory basis, our named executive officer compensation, (3) recommend, on an advisory basis, “every one year” as the frequency of future advisory votes to approve our named executive officer compensation, (4) ratify the appointment of Deloitte and Touche LLP as our independent registered public accounting firm and (5) approve the issuance of the shares of Class A common stock issuable upon the conversion of the Series A Preferred Stock.

How can I authorize my proxy online or via telephone?

In order to authorize your proxy online or via telephone, go to www.proxyvote.com or call the toll-free number reflected on the Notice, and follow the instructions. If your shares of common stock are held in the name of your broker, a bank or other nominee in “street name,” that party will give you instructions for voting your shares. Please have your Notice in hand when accessing the site, as it contains a Control Number required for access. You can authorize your proxy electronically via the internet or by telephone at any time prior to 11:59 p.m. Eastern Time, on June 8, 2026, the day before the Annual Meeting.

If you received paper proxy materials, you may also refer to the enclosed Proxy Card for instructions. If you choose not to authorize your proxy electronically, please complete and return the paper Proxy Card in the pre-addressed, postage-paid envelope provided.

Table of Contents

What if other matters come up at the Annual Meeting?

As of the date of this Proxy Statement, the only matters we know of that will be voted on at the Annual Meeting are the proposals we have described herein. If other matters are properly presented at the Annual Meeting, the designated proxies will vote your shares at their discretion.

Can I change my previously authorized vote?

Yes, you can change your vote at any time before the vote on a proposal either by executing or authorizing, dating and delivering to us a new proxy electronically via the internet, by telephone or by mail at any time prior to 11:59 p.m. Eastern Time, on June 8, 2026, the day before the Annual Meeting, by giving us a written notice revoking your Proxy Card or by attending the Annual Meeting virtually and voting your shares during the Annual Meeting. Your virtual attendance at the Annual Meeting will not, by itself, revoke a proxy previously given by you. We will honor the latest dated proxy.

Proxy revocation notices or new proxy cards should be sent to Infinity Natural Resources, Inc., 2605 Cranberry Square, Morgantown, West Virginia, 26508 Attention: General Counsel and Secretary.

Can I vote during the Annual Meeting rather than by authorizing a proxy?

You can virtually attend the Annual Meeting and vote your shares during the Annual Meeting; however, we encourage you to authorize your proxy to ensure that your vote is counted. Authorizing your proxy electronically or telephonically, or submitting a Proxy Card, will not prevent you from later attending the Annual Meeting and voting your shares during the Annual Meeting.

Will my shares be voted if I do not provide my proxy?

Depending on the proposal, your shares may be voted if they are held in the name of a brokerage firm, even if you do not provide the brokerage firm with voting instructions. Brokerage firms have the authority under the NYSE rules to cast votes on certain “routine” matters if they do not receive instructions from their customers. The Auditor Ratification Proposal is considered a “routine” matter for which brokerage firms may vote shares without receiving voting instructions.

Brokerage firms do not have the authority under the NYSE rules to vote on non-routine matters, which include the Director Election Proposal, the Say-On-Pay Proposal, the Say-On-Frequency Proposal and the Stock Issuance Proposal. If you do not provide the brokerage firm with voting instructions on these proposals, your shares will not be voted and will result in “broker non-votes.” Broker non-votes will be considered present for the purpose of determining whether we have a quorum. Broker non-votes will not have an effect on Director Election Proposal, the Say-On-Pay Proposal, the Say-On-Frequency Proposal and the Stock Issuance Proposal.

What do I do if my shares are held in “street name”?

If your shares of common stock or Series A Preferred Stock are held in the name of your broker, a bank or other nominee in “street name,” that party will give you instructions for voting your shares. If your shares of common stock or Series A Preferred Stock are held in “street name” and you would like to electronically vote your shares during the Annual Meeting, you must contact your broker, bank or other nominee to obtain a proxy form from the record holder of your shares.

Who will count the votes?

A representative of The Carideo Group, Inc. will count the votes and will serve as the independent inspector of election.

Table of Contents

Who pays for this proxy solicitation?

We do. We will reimburse banks, brokers and other custodians, nominees and fiduciaries representing beneficial owners of shares of common stock for their expenses in forwarding soliciting materials to beneficial owners of shares of common stock and in obtaining voting instructions from those owners. In addition to sending you these materials, some of our employees or agents may contact you by telephone, by mail or in person. None of our employees will receive any extra compensation for providing those services.

What are the implications of being an “emerging growth company?”

We are an “emerging growth company” as that term is used in the Jumpstart Our Business Startups Act of 2012 and, as such, have elected to comply with certain reduced public company reporting requirements. These reduced reporting requirements include reduced disclosure about our executive compensation arrangements.

We will remain an emerging growth company until the earlier of: (a) the last day of the year following the fifth anniversary of the consummation of our IPO, (b) the last day of the year in which we have total annual gross revenue of at least $1.235 billion, (c) the last day of the year in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the last business day of the second quarter of such year, or (d) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.
