This Statement relates to the common stock, $0.01 par value per share (the "Common Stock"), of U.S. Energy Corp., a Delaware corporation (the "Issuer" or the "Company"). The principal executive offices of the Issuer are located at 1616 S. Voss Rd., Suite 725, Houston, Texas, 77057.

**Item 4. Purpose of Transaction**

The information set forth in Item 3 is hereby incorporated by reference into this Item 4.

The Reporting Persons acquired the securities for investment purposes. In the future, depending on general market and economic conditions affecting the Issuer and other relevant factors, the Reporting Persons may purchase additional securities of the Issuer or dispose of some or all of the securities they currently own from time to time in open market transactions, private transactions (including gifts) or otherwise.

Except as may occur in the ordinary course of business of the Issuer and as discussed herein, the Reporting Persons do not currently have any plans or proposals which relate to or would result in the following described:

(a)  The acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer;

(b)  An extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries;

(c)  A sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries;

(d)  Any change in the present board of directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board;

(e)  Any material change in the present capitalization or dividend policy of the Issuer;

(f)  Any other material change in the Issuer's business or corporate structure, including but not limited to, if the Issuer is a registered closed-end investment company, any plans or proposals to make any changes in its investment policy for which a vote is required by section 13 of the Investment Company Act of 1940;

(g)  Changes in the Issuer's charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person;

(h)  Causing a class of securities of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association;

(i)  A class of equity securities of the Issuer becoming eligible for termination of registration pursuant to section 12(g)(4) of the Act; or

(j)  Any action similar to any of those enumerated above (except as discussed below).

The Reporting Persons retain the right to change their investment intent, and may, from time to time, acquire additional shares of Common Stock or other securities of the Issuer, or sell or otherwise dispose of (or enter into a plan or arrangements to sell or otherwise dispose of), all or part of the shares of Common Stock or other securities of the Issuer, if any, beneficially owned by them, in any manner permitted by law.

Additionally, Mr. Weinzierl, in his capacity as Chairman of the Board of the Issuer, may from time to time, become aware of, initiate, and/or be involved in discussions that relate to the transactions described in this Item 4 and thus retains his right to modify his plans with respect to the transactions described in this Item 4 and to formulate plans and proposals that could result in the occurrence of any such events, subject to applicable laws and regulations. Mr. Weinzierl also engages in discussions with management, directors and other stockholders of the Issuer that have in the past included, and in the future are expected to include, transactions with affiliates of the Reporting Person or their respective affiliates, which own or control interests in other assets that may be deemed of interest to the Issuer. These discussions include informal, exploratory discussions as well as asset evaluations and discussions regarding potential structuring matters associated with potential transactions as part of determining their feasibility for any proposal or plan by the Issuer or such Reporting Persons. Any such transactions would depend on various factors including, without limitation, the Issuer's financial position and strategic direction, price levels of the Common Stock, conditions in the securities market and general economic and industry conditions, as well as alternative opportunities available to the Reporting Persons with respect to assets owned or controlled by the Reporting Persons or their affiliates.

Following the distribution of shares of Common Stock by Lubbock Energy Partners LLC, a Texas limited liability company ("Lubbock"), on July 19, 2022, Lubbock no longer owns any shares of Common Stock; however, Lubbock continues to have certain rights under the Nominating and Voting Agreement by virtue of its affiliates continuing to own more than 5% of the Issuer's outstanding shares of Common Stock (including Mr. Weinzierl and others as affiliates), and Mr. Weinzierl may cause Lubbock to exercise combined voting power with respect to the nomination of directors pursuant to the Nominating and Voting Agreement.

As discussed above in Item 3, pursuant to the Issuer's 2022 Equity Incentive Plan, nonqualified stock options were granted to Mr. Weinzierl on March 6, 2026. The options will vest in two equal annual installments of 50% each: 230,000 options on July 1, 2026 and 230,000 options on January 2, 2027, subject to Mr. Weinzierl's continued service with the Issuer on such vesting dates.

On April 29, 2026, Katla Energy Holdings LLC distributed an aggregate of 1,818,000 shares to Mr. Weinzierl and his spouse, and Mr. Weinzierl and his spouse gifted (a) 909,000 shares to John Alfred Weinzierl 2020 Trust u/a November 10, 2020 and (b) 909,000 shares to a trust for which the spouse of Mr. Weinzierl serves as trustee.
