[8-K] PHX Minerals Inc. Reports Material Event

Rhea-AI Filing Summary

PHX Minerals (NYSE:PHX) filed an 8-K to confirm the closing of its cash sale to WhiteHawk Income Corporation. On June 23 2025, following a successful tender offer in which 28,806,761 shares (73.7%) were validly tendered at $4.35 per share, WhiteHawk Merger Sub was merged into PHX under DGCL §251(h); PHX survived as a wholly-owned subsidiary of WhiteHawk. The transaction delivers approximately $187 million in aggregate consideration to PHX stockholders.

Concurrently, PHX became a secured guarantor under WhiteHawk’s Amended Note Purchase Agreement dated September 17 2024, pledging substantially all of its assets. PHX also paid off and terminated its 2021 revolving Credit Agreement.

With the change in control complete, trading in PHX common stock has been suspended; the NYSE has filed Form 25 to delist the shares, and PHX intends to file Form 15 to suspend Exchange Act reporting. All outstanding restricted shares, performance units, and deferred compensation units were converted to the same $4.35 cash consideration (plus accrued dividends) on accelerated or scheduled timetables.

The filing therefore records (i) entry into and termination of material debt agreements, (ii) completion of the merger, (iii) creation of new secured obligations, (iv) change in control, and (v) delisting and deregistration of PHX securities.

Positive

• Shareholders receive an immediate $4.35 per share cash payout, representing approximately $187 million in total consideration.
• Tender offer succeeded with 73.7% participation, enabling prompt closing under DGCL §251(h) without additional vote.

Negative

• PHX common stock is delisted from the NYSE; public investors will no longer have trading liquidity or disclosure access.
• PHX becomes a secured guarantor of WhiteHawk’s note obligations, pledging substantially all assets and increasing leverage risk.

Insights

M&A Specialist

TL;DR – Cash buyout closes; shareholders receive $4.35 and stock disappears.

The filing signals final consummation of the WhiteHawk acquisition. A 73.7% tender met the minimum condition, enabling the swift §251(h) back-end merger without further shareholder vote. Cash consideration totals roughly $187 million, giving all remaining holders an identical exit price. The deal converts restricted and deferred equity into cash, removing overhang. From a value-realisation standpoint, the event is positive—investors lock in liquidity at a pre-defined price and eliminate future commodity-cycle volatility. Closing within six weeks of offer launch demonstrates clean diligence and financing certainty (debt plus equity). Minority squeeze-out risk is eliminated because consideration mirrors the tender terms.

Corporate Governance & Credit Analyst

TL;DR – Merger adds leverage and ends public-company disclosures.

Post-closing, PHX guarantees WhiteHawk’s amended notes, granting lenders a first-priority lien on nearly all assets; this materially subordinates any residual equity value for future owners. Termination of the unsecured 2021 revolver tightens covenant flexibility under the new note structure. Delisting and planned Form 15 will eliminate ongoing SEC reporting, reducing transparency for remaining stakeholders such as bondholders and royalty interest holders. While neutral to current cash-out investors, these features tilt risk higher for creditors and employees who now depend on an over-levered parent. Overall impact mixed: immediate liquidity for shareholders is offset by diminished governance and increased balance-sheet encumbrance.

As previously disclosed in the Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”) by PHX Minerals, Inc. (the “Company” or “PHX”) on May 12, 2025, PHX entered into an Agreement and Plan of Merger (the “Merger Agreement”), dated May 8, 2025, by and among WhiteHawk Acquisition, Inc., a Delaware corporation (“Parent”), a wholly owned subsidiary of WhiteHawk Income Corporation (“WHIC”), WhiteHawk Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Purchaser”), and PHX. Pursuant to the Merger Agreement, Purchaser commenced a cash tender offer to purchase all of the issued and outstanding shares of the Company’s common stock, par value $0.01666 per share (the “Shares”), for a purchase price of $4.35 per Share (the “Offer Price”), net to the seller in cash, without interest thereon and subject to any required tax withholding, upon the terms and subject to the conditions set forth in the Offer to Purchase dated May 22, 2025 (the “Offer to Purchase”), and in the related Letter of Transmittal (which, together with the Offer to Purchase, as each may be amended or supplemented from time to time, constitute the “Offer”).

Item 1.01 Entry into a Material Definitive Agreement

On June 23, 2025, after giving effect to the transactions contemplated by the Merger Agreement, PHX became a guarantor of the indebtedness under that certain Note Purchase Agreement, dated as of September 17, 2024 (as amended including in connection with the consummation of the transactions contemplated by the Merger Agreement, the “Amended Note Purchase Agreement”), by and among WHIC, the holders party thereto and U.S. Bank Trust Company, National Association, as administrative agent.

The obligations under the Amended Note Purchase Agreement, and the guarantees of those obligations (as well as certain hedging or swap agreements), are secured by substantially all of PHX’s assets.

Item 1.02 Termination of a Material Definitive Agreement

On June 23, 2025, after giving effect to the transactions contemplated by the Merger Agreement, the Company paid in full and terminated that certain Credit Agreement dated as of September 1, 2021 (as amended, restated, amended and restated, replaced, supplemented or otherwise modified from time to time, the “Credit Agreement”), among the Company, SouthState Bank, N.A., successor by merger to Independent Bank, as administrative agent and SouthState Bank, N.A., MidFirst Bank, UMB Bank, N.A., and all other banks and financial institutions from time to time party to the Credit Agreement.

Item 2.01 Completion of Acquisition or Disposition of Assets.

The Offer and withdrawal rights expired as scheduled at 12:00 midnight, New York City Time, at the end of June 20, 2025 (such date and time, the “Expiration Time”), without being extended. Computershare Trust Company, N.A., the depositary (the “Depositary”) for the Offer, advised that, as of the Expiration Time: (i) 28,806,761 Shares (excluding Shares tendered pursuant to guaranteed delivery procedures that are not yet delivered in settlement or satisfaction of such guarantee) had been validly tendered and not properly withdrawn pursuant to the Offer, representing approximately 73.7% of the aggregate number of issued and outstanding Shares as of the Expiration Time. Accordingly, the number of Shares validly tendered and not withdrawn pursuant to the Offer satisfies the Minimum Condition (as defined in the Merger Agreement). As a result of the satisfaction of the Minimum Condition and each of the other conditions to the Offer, Purchaser has accepted for payment all Shares that were validly tendered and not properly withdrawn pursuant to the Offer. In addition, the Depositary has advised that, as of the Expiration Time, 50,315 Shares have been tendered by Notice of Guaranteed Delivery, representing approximately 0.1% of the aggregate number of then issued and outstanding Shares.

On June 23, 2025, pursuant to the terms of the Merger Agreement and in accordance with Section 251(h) of the Delaware General Corporation Law (“DGCL”), Purchaser was merged with and into PHX (the “Merger”), with PHX being the surviving corporation (the “Surviving Corporation”). Upon completion of the Merger, PHX became a wholly owned subsidiary of Parent.

At the effective time of, and as a result of, the Merger and pursuant to the terms and subject to the conditions of the Merger Agreement, each Share (other than Shares (i) owned directly by the Company as treasury stock, Parent, Merger Sub or any of their respective affiliates, which Shares were automatically cancelled and ceased to exist, (ii) owned by any Stockholder who is entitled to demand and properly demanded the appraisal of such Shares in accordance with, and in compliance in all respects with Section 262 of the DGCL or (iii) that were Time-Based Restricted Shares or Performance-Based Restricted Shares, each as described below) were automatically cancelled and converted into the right to receive an amount in cash equal to the Offer Price, without interest and subject to applicable tax withholding (the “Merger Consideration”).

In addition, immediately prior to the effective time of the Merger, (i) each outstanding share of time-based restricted stock of the Company (“Time-Based Restricted Shares”) ceased to represent a Time-Based Restricted Share and was cancelled and converted into a right to receive an amount in cash, without interest (a “Restricted Cash Award”) equal to the sum of (A) the product of (x) the number of Shares subject to such Time-Based Restricted Share immediately prior to the effective time of the Merger and (y) the Merger Consideration, plus (B) the accrued and unpaid dividends, as of immediately prior to the effective time of the Merger, with respect to such Time-Based Restricted Shares; (ii) each outstanding share of performance-based restricted stock of the Company (“Performance-Based Restricted Shares”) vested in full (assuming achievement of maximum performance), became free of restrictions and was automatically cancelled and terminated and converted into the right to receive an amount in cash (without interest) equal to the sum of (A) the Merger Consideration and (B) the accrued and unpaid dividends, as of immediately prior to the effective time of the Merger, with respect to such Performance-Based Restricted Share (the “Performance-Based Restricted Share Consideration”); and (iii) each outstanding right to receive Shares in accordance with the Company’s Deferred Compensation Plan for Non-Employee Directors (each, a “DCP Unit”) was automatically cancelled and terminated and converted into the right to receive an amount in cash (without interest) equal to the product obtained by multiplying (A) the aggregate number of Shares subject to such DCP Unit, by (B) the Merger Consideration (the “DCP Unit Consideration”). Except as set forth in the Merger Agreement, each Restricted Cash Award shall be governed by substantially similar terms and conditions (including vesting and forfeiture terms) as were applicable to the corresponding Time-Based Restricted Shares immediately prior to the effective time of the Merger, provided that each Restricted Cash Award shall vest and become payable upon the earlier of (X) the date the corresponding Time-Based Restricted Share would have vested pursuant to the terms thereof and (Y) 90 days following the Closing Date. Each Restricted Cash Award, less any applicable withholding taxes, will be paid as soon as reasonably practicable by the Surviving Corporation following the date such Restricted Cash Award becomes so payable (but in any event no later than three business days thereafter). The Performance-Based Restricted Share Consideration, less any applicable withholding taxes, will be paid as soon as reasonably practicable by the Surviving Corporation following the date hereof (and in no event later than three business days thereafter). The DCP Unit Consideration will be paid as promptly as practicable by the Surviving Corporation (and in no event later than five business days) after the date hereof, provided that if the DCP Unit Consideration constitutes nonqualified deferred compensation subject to Section 409A of the United States Internal Revenue Code of 1986, as amended (the “Code”) such payment shall be made at the earliest time permitted under the applicable Company equity plan and deferral election form that will not trigger a tax or penalty under Section 409A of the Code.

The aggregate consideration paid by Parent and Purchaser in the Offer and Merger was approximately $187 million, without giving effect to related transaction fees and expenses. Parent and Purchaser funded the consideration paid to stockholders in the Offer and pursuant to the Merger through the Debt Financing and the Equity Financing, each as defined in the Merger Agreement.
