(b)	Name of Issuer: PHX Minerals Inc.
(c)	Address of Issuer's Principal Executive Offices: 1320 South University Drive, Suite 720, Fort Worth, TEXAS , 76107.
Item 1 Comment: This Amendment No. 1 to Schedule 13D (this "Amendment") relates to the Common Stock, par value $0.01666 per share (the "Shares") of PHX Minerals Inc., a Delaware corporation (the "Issuer") and amends the initial statement on Schedule 13D filed on May 15, 2025 (the "Original 13D"). Unless otherwise specified, capitalized terms used but not otherwise defined in this Amendment shall have the meanings ascribed to them in the Original 13D. On June 23, 2025, the Issuer, Parent, and Merger Sub completed the transactions contemplated by the Agreement and Plan of Merger, dated May 8, 2025, by and among the Issuer, Parent, and Merger Sub (the "Merger Agreement"). Pursuant to the terms of the Merger Agreement, Merger Sub merged with and into the Issuer (the "Merger"), with the Issuer surviving (the "Surviving Corporation") the Merger as a subsidiary of Parent.
Item 4.	Purpose of Transaction
	Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following at the end thereof: On June 21, 2025, Merger Sub accepted for payment all Shares that were validly tendered and not properly withdrawn pursuant to the Offer. On June 23, 2025, pursuant to the terms of the Merger Agreement, Merger Sub merged with and into the Issuer, with the Issuer surviving the Merger as a subsidiary of Parent. At the Effective Time, as a result of the Merger, each Share issued and outstanding immediately prior to the Effective Time (other than Shares (i) owned directly by the Issuer 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 the DGCL or (iii) that were Time-Based Restricted Shares or Performance-Based Restricted Shares, each as described in the Original 13D) 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. At the Effective Time, the 100 shares of common stock of Merger Sub that were outstanding immediately prior to the Effective Time were converted into and became 100 shares of common stock of the Surviving Corporation. Upon the closing of the Merger, the Shares that previously traded under the ticker symbol "PHX", ceased trading on, and are being delisted from, the New York Stock Exchange. In connection with the merger, each member of the Board of Directors of the Issuer resigned from the Board of Directors of the Issuer, including any committee thereof. At the Effective Time, the size of the Board of Directors of the Issuer was reduced to one member, and Jeffrey Slotterback was appointed as the sole member of the Board of Directors of the Issuer. At the Effective Time, the officers of Merger Sub immediately prior to the Effective Time became the officers of the Issuer following the Effective Time. In connection with the Offer, WhiteHawk LP tendered 946,606 Shares into the Offer. As a result, the Holding Parties no longer beneficially own any securities of the Issuer.
