Luminus stake in Battalion Oil (BATL) tops 50% with 16.4M shares

Rhea-AI Filing Summary

Luminus Management and affiliated funds report beneficial ownership of 16,402,225 Battalion Oil common shares, representing 50.4% of the class. This stake includes both shares already owned and shares issuable upon conversion or redemption of multiple series of preferred stock held by Luminus Energy Partners Master Fund.

The Master Fund effected an in-kind distribution of 5,200,000 Battalion Oil shares to its feeder funds and affiliates, which then distributed shares to investors holding illiquid certificates. Certificate holders entitled to 1,145,542 shares did not complete delivery requirements, so the Master Fund continues to hold these “Segregated Shares” with voting and disposition power but no economic interest, for the benefit of those investors.

Insights

Equity ownership analyst

Luminus discloses a controlling‑level stake and redistributes 5.2M shares in kind.

Luminus Management, its Master Fund, and Jonathan Barrett collectively report beneficial ownership of 16,402,225 shares of Battalion Oil common stock, or 50.4% of the class. This figure is based on 18,256,563 outstanding common shares plus shares issuable from several preferred series.

The filing details an in-kind distribution of 5,200,000 shares from the Master Fund to feeder funds and affiliates, followed by distributions to holders of illiquid certificates. Because some investors did not or could not receive their allocations, 1,145,542 “Segregated Shares” remain with the Master Fund, which retains voting and disposition power while expressly stating it has no economic interest in those shares.

The reporting persons also describe voting agreements with other holders and repeatedly disclaim being part of a formal Section 13(d) “group” or owning any shares held by those counterparties. Overall, the amendment refines how a large, potentially controlling stake is held and administered, rather than indicating new capital flows or valuation metrics.

SCHEDULE 13D

Item 1.	Security and Issuer
(a)	Title of Class of Securities: Common Stock
(b)	Name of Issuer: BATTALION OIL CORP
(c)	Address of Issuer's Principal Executive Offices: 820 Gessner Road, Suite 1100, Houston, TEXAS , 77024.
Item 4.	Purpose of Transaction
	Item 4 is hereby amended by adding the following: On March 24, 2026, the Master Fund effected a distribution in kind of 5,200,000 shares (the "Shares") of common stock of the Issuer in the aggregate to: (i) its two feeder funds, Luminus Energy Partners QP, LP, a Delaware limited partnership ("LEP Onshore"), which received 2,117,138 Shares, and LEP Offshore (through LILP, an intermediary entity which received 2,641,190 Shares); and (ii) two affiliates that have economic interests in the Master Fund, namely LCP Onshore, which received 391,694 Shares, and LCP Offshore, which received 91,930 Shares. Each of the Funds had issued illiquid certificates to their respective investors on April 1, 2020 (collectively, the "Illiquid Certificates"). The Funds concurrently distributed the Shares to the holders of the Illiquid Certificates (collectively, the Certificate Holders"). For ease of mechanics, calculations were made on a look-through basis with the Master Fund distributing the Shares directly to the Certificate Holders and to LILP. The distribution in kind was made pursuant the terms of the Illiquid Certificates and the constituent documents of the respective Funds. In connection with the distribution in kind, the Manager planned to distribute 5,200,000 shares of common stock. As Certificate Holders entitled to receive 1,145,542 shares of common stock (the "Segregated Shares") in the aggregate did not either (i) respond or provide the requisite information to the Fund's administrator and the Manager to receive the Segregated Shares, (ii) were unable to accept delivery of the Segregated Shares or (iii) chose not to participate in the distribution (such Certificate Holders being referred to as the "Non Returners"), the Master Fund continues to hold the Segregated Shares and retains both voting and disposition power over the Segregated Shares. The Master Fund, however, has no economic interest in the Segregated Shares as the Master Fund is holding the Segregated Shares for the benefit of the Non Returners. The Master Fund can, in its discretion, sell the Segregated Shares on behalf of the Non Returners and/or make one or more distribution in kind of the Segregated Shares to the Non Returners who provide their requisite information.
Item 5.	Interest in Securities of the Issuer
(a)	The information set forth in rows 11 and 13 of the cover pages to this Schedule 13D is incorporated by reference. The percentage set forth in row 13 is based on (i) 18,256,563 outstanding shares of Common Stock as of March 18, 2024, based on the number of shares outstanding as reported by the Issuer in its Annual Report on Form 10-K filed with the SEC on March 23, 2026, plus (ii) (a) 2,361,487 shares of Common Stock issuable upon conversion or redemption of 13,336 shares of Series A Preferred Stock owned directly by Master Fund, (b) 3,962,723 shares of Common Stock issuable upon conversion or redemption of 20,269 shares of Series A-1 Preferred Stock owned directly by Master Fund, (c) 3,960,226 shares of Common Stock issuable upon conversion or redemption of 17,211 shares of Series A-2 Preferred Stock owned directly by Master Fund, (d) 1,968,326 shares of Common Stock issuable upon conversion or redemption of 9,835 shares of Series A-3 Preferred Stock and (e) 2,052,473 shares of Common Stock issuable upon conversion or redemption of 9,835 shares of Series A-4 Preferred Stock owned directly by Master Fund. Due to the nature of the Voting Agreement, the Reporting Persons may be deemed to be members of a "group," within the meaning of Section 13d-5 of the Act, comprised of the Reporting Persons and the Voting Agreement Members. Shares listed as beneficially owned by each Reporting Person exclude shares held by any of the Voting Agreement Members. The Reporting Persons hereby expressly disclaim beneficial ownership of any Common Stock beneficially owned by any of the Voting Agreement Members or any other person, and do not affirm membership in a "group" (within the meaning of Rule 13d-5 of the Act) with any of the Voting Agreement Members or any other person, and this Schedule 13D shall not be construed as acknowledging that the Reporting Persons, for any or all purposes, beneficially owns any Common Stock beneficially owned by any of the Voting Agreement Members or any other person or is a member of a group with any of the Voting Agreement Members or any other person.
(b)	The information set forth in rows 7 through 10 of the cover pages to this Schedule 13D is incorporated by reference.
(c)	Except as set forth herein, no transactions in the Common Stock were effected during the past sixty days by any Reporting Person.
(d)	No person (other than the Reporting Persons) is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the shares of Common Stock subject to this Schedule 13D
(e)	Not applicable.
