## Exhibit 99.1

**TXO PARTNERS, L.P.**

**PRO FORMA FINANCIAL STATEMENTS**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(Unaudited)**

**Introduction**

TXO Partners, L.P. ("TXO Partners") engages in oil and natural gas exploration and production. The unaudited pro forma financial statements have been prepared in accordance with Article 11 of Regulation S-X, using assumptions set forth in the notes to the unaudited pro forma financial statements. The following unaudited pro forma financial statements of the TXO Partners reflect the historical results of TXO Partners, on a pro forma basis to give effect to the following transactions, which are described in further detail below, as if they had occurred on March 31, 2026, for pro forma balance sheet purposes, and on January 1, 2025, for pro forma statement of operations purposes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•in the case of the unaudited pro forma statements of operations, the disposition of oil and gas properties of Cross Timbers Energy, LLC ("Cross Timbers") to multiple buyers in April and May 2026 ("CTE Disposition");

The unaudited pro forma balance sheet of TXO Partners is based on the historical balance sheet of TXO Partners as of March 31, 2026 and includes pro forma adjustments to give effect to the described transactions as if they had occurred on March 31, 2026. The unaudited pro forma statements of operations of TXO Partners are based on the audited historical statement of operations of TXO Partners for the year ended December 31, 2025, and the unaudited historical statement of operations of TXO Partners for the three months ended March 31, 2026, both having been adjusted to give effect to the described transaction as if they occurred on January 1, 2025.

The pro forma data presented reflect events directly attributable to the described transaction and certain assumptions TXO Partners believes are reasonable. The pro forma data are not necessarily indicative of financial results that would have been attained had the described transaction occurred on the date indicated or which could be achieved in the future because they necessarily exclude various operating efficiencies, such as decreased general and administrative expenses associated with being a smaller company. The adjustments are based on currently available information and certain estimates and assumptions. Therefore, the actual adjustments may differ from the pro forma adjustments. However, management believes that the assumptions provide a reasonable basis for presenting the significant effects of the transaction and the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited financial statements.

The unaudited pro forma financial statements and related notes are presented for illustrative purposes only. If the CTE Disposition described herein had occurred in the past, TXO Partners' operating results might have been materially different from those presented in the unaudited pro forma financial statements. The unaudited pro forma financial statements should not be relied upon as an indication of operating results that TXO Partners would have achieved if the CTE Disposition described herein had taken place on the specified date. In addition, future results may vary significantly from the results reflected in the unaudited pro forma financial statements of operations and should not be relied upon as an indication of the future results TXO Partners will have after the CTE Disposition described herein by these unaudited pro forma financial statements.

The accompanying notes are an integral part of these unaudited pro forma financial statements.

**TXO PARTNERS, L.P.**

**1. BASIS OF PRESENTATION AND CORPORATE REORGANIZATION**

The historical financial information is derived from the financial statements of TXO Partners included in the Annual Report on Form 10-K for the year ended December 31, 2025 and in the Quarterly Report on Form 10-Q for the three months ended March 31, 2026. For purposes of the unaudited pro forma balance sheet and statements of operations, it is assumed that the CTE Disposition had taken place on January 1, 2025.

**2. PRO FORMA ADJUSTMENTS AND ASSUMPTIONS**

TXO Partners made the following adjustments and assumptions in the preparation of the unaudited pro forma financial statements:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Adjustment reflects the CTE Disposition proceeds, to TXO Partners, used to pay down outstanding debt on our Credit Facility and removal of related oil and gas assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Adjustment reflects the removal of the management fee paid by CTE to TXO Partners.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Adjustment reflects savings in interest expense from disposition proceeds used to pay down debt, had such the transaction closed on January 1, 2025. The average interest rate was 7.9% for the year ended December 31, 2025 and 7.4% for the three months ended March 31, 2026.

**3. SUPPLEMENTARY DISCLOSURE OF OIL AND NATURAL GAS OPERATIONS**

The following pro forma standardized measure of the discounted net future cash flows and changes applicable to TXO Partners' proved reserves reflect the effect of Texas state franchise taxes which TXO Partners is subject to. The future cash flows are discounted at 10% per year and assume continuation of existing economic conditions.

The standardized measure of discounted future net cash flows, in management's opinion, should be examined with caution. The basis for this table is the reserve studies prepared by independent petroleum engineering consultants, which contain imprecise estimates of quantities and rates of production of reserves. Revisions of previous year estimates can have a significant impact on these results. Also, exploration costs in one year may lead to significant discoveries in later years and may significantly change previous estimates of proved reserves and their valuation. Therefore, the standardized measure of discounted future net cash flow is not necessarily indicative of the fair value of TXO Partners' proved oil and natural gas properties.

The data presented should not be viewed as representing the expected cash flow from, or current value of, existing proved reserves since the computations are based on a large number of estimates and assumptions. Reserve quantities cannot be measured with precision, and their estimation requires many judgmental determinations and frequent revisions. Actual future prices and costs are likely to be substantially different from the prices and costs utilized in the computation of reported amounts.

The following table provides a pro forma rollforward of the total proved reserves for the year ended December 31, 2025, as well as pro forma proved developed and proved undeveloped reserves at the beginning and end of the year, as if the CTE Disposition occurred on January 1, 2025.
