FOR IMMEDIATE RELEASE

PHX Minerals Reports Results for the Quarter Ended March 31, 2025 and Announces Dividend Payment

FORT WORTH, Texas, May 8, 2025 – PHX MINERALS INC., “PHX” or the “Company” (NYSE: PHX), today reported financial and operating results for the quarter ended March 31, 2025.

Summary of Results for the Quarter Ended March 31, 2025

Subsequent Events

Chad L. Stephens, President and CEO, commented,“PHX had a strong start to 2025, delivering solid cash flow and adjusted EBITDA on both a sequential and year-over-year basis.  The closing of our recent divestiture of non-producing minerals in January, along with strong cash generation, enabled us to further reduce our debt to $19.8 million as of March 31, 2025, resulting in a debt-to-adjusted EBITDA (TTM) ratio under 1x. A strong and flexible balance sheet continues to be an important part of our strategy.”

“The natural gas environment showed meaningful improvement during the first quarter driven by tightening supply-demand dynamics, colder-than-expected winter weather, and increasing liquefied natural gas (LNG) export demand. This backdrop is translating into heightened operator activity across our mineral acreage as demonstrated by a higher gross and net number of wells in progress as of the quarter end. We expect this trend to continue throughout 2025 and into 2026, supporting the increased production volumes and enhanced cash flow from our assets.”

Quarter Ended March 31, 2025 Results

The Company recorded net income of $4.4 million, or $0.12 per diluted share, for the quarter ended March 31, 2025, as compared to net loss of $(0.2) million, or $(0.01) per diluted share, for the quarter ended March 31, 2024. The change in net income was principally the result of an increase in natural gas, oil and NGL sales and an increase in gain on asset sales, partially offset by an increase in losses associated with derivative contracts, an increase in general and administrative expenses, and an increase in transportation, gathering and marketing expenses.

Natural gas, oil and NGL revenue increased $3.3 million, or 47%, for the quarter ended March 31, 2025, compared to the quarter ended March 31, 2024, due to increases in natural gas and NGL prices of 83% and 26%, respectively, and increases in natural gas and oil volumes of 2% and 14%, respectively, partially offset by a decrease in oil price of 7% and a decrease in NGL volumes of 9%.

The increase in royalty production volumes during the quarter ended March 31, 2025, as compared to the quarter ended March 31, 2024, resulted primarily from new wells being brought online in the Haynesville Shale and SCOOP plays.

The Company had a net loss on derivative contracts of ($3.2) million for the quarter ended March 31, 2025, comprised of a ($0.2) million loss on settled derivatives and a ($2.9) million non-cash loss on derivatives, as compared to a net gain of $0.6 million for the quarter ended March 31, 2024. The change in net gain (loss) on derivative contracts was due to the Company’s settlements of natural gas and oil collars and fixed price swaps and the change in valuation caused by the difference in March 31, 2025 pricing relative to the strike price on open derivative contracts.

Operations Update

During the quarter ended March 31, 2025, the Company converted 65 gross (0.113 net) wells to producing status, including 5 gross (0.009 net) wells in the Haynesville and 26 gross (0.036 net) wells in the SCOOP, compared to 85 gross (0.32 net) wells converted in the quarter ended March 31, 2024.

At March 31, 2025, the Company had a total of 247 gross (1.017 net) wells in progress and permits across its mineral positions, compared to 225 gross (0.91 net) wells in progress and permits at Dec 31, 2024. As of March 31, 2025, 18 rigs were operating on the Company’s acreage and 70 rigs were operating within 2.5 miles of its acreage.

(1) Wells in progress includes drilling wells and drilled but uncompleted wells, or DUCs.

Leasing Activity

During the quarter ended March 31, 2025, the Company leased 397 net mineral acres to third-party exploration and production companies for an average bonus payment of $911 per net mineral acre and an average royalty of 25%.

Acquisition and Divestiture Update

During the quarter ended March 31, 2025, the Company purchased 50 net royalty acres for approximately $0.6 million and sold 165,326 acres, which were outside the Company’s core focus areas and predominately undeveloped and unleased, for approximately $7.9 million.

Non-GAAP Reconciliation

This press release includes certain “non-GAAP financial measures” as defined under the rules and regulations of the U.S. Securities and Exchange Commission, or the SEC, including Regulation G. These non-GAAP financial measures are calculated using GAAP amounts in the Company’s financial statements. These measures, detailed below, are provided in addition to, not as an alternative for, and should be read in conjunction with, the information contained in the Company’s financial statements prepared in accordance with GAAP (including the notes thereto), included in the Company’s SEC filings and posted on its website.

Adjusted EBITDA Reconciliation

The Company defines “adjusted EBITDA” as earnings before interest, taxes, depreciation and amortization, or EBITDA, excluding non-cash gains (losses) on derivatives and gains (losses) on asset sales, but including cash receipts from (payments on) off-market derivatives, and further excluding professional fees associated with announced strategic alternatives process and restricted stock and deferred directors’ expense. In prior releases, the Company generally has not excluded professional fees in defining adjusted EBITDA, but has excluded professional fees associated with the announced strategic alternatives process in defining adjusted EBITDA in this press release as the Company believes excluding these particular fees in the presentation of adjusted EBITDA may be useful to investors in their evaluation of the Company’s financial performance. The Company has included a presentation of adjusted EBITDA because it recognizes that certain investors consider this amount to be a useful means of measuring the Company’s ability to meet its debt service obligations and evaluating its financial performance. Adjusted EBITDA has limitations and should not be considered in isolation or as a substitute for net income, operating income, cash flow from operations or other consolidated income or cash flow data prepared in accordance with GAAP. Because not all companies use identical calculations, this presentation of adjusted EBITDA may not be comparable to a similarly titled measure of other companies. The following table provides a reconciliation of net income (loss) to adjusted EBITDA for the quarters indicated:

Debt-to-Adjusted EBITDA (TTM) Reconciliation

“Debt-to-adjusted EBITDA (TTM)” is defined as the ratio of long-term debt to adjusted EBITDA on a trailing 12-month (TTM) basis. The Company has included a presentation of debt-to-adjusted EBITDA (TTM) because it recognizes that certain investors consider such ratios to be a useful means of measuring the Company’s ability to meet its debt service obligations and for evaluating its financial performance. The debt-to-adjusted EBITDA (TTM) ratio has limitations and should not be considered in isolation or as a substitute for net income, operating income, cash flow from operations or other consolidated income or cash flow data prepared in accordance with GAAP. Because not all companies use identical calculations, this presentation of debt-to-adjusted EBITDA (TTM) may not be comparable to a similarly titled measure of other companies. The following table provides a reconciliation of net income (loss) to adjusted EBITDA on a TTM basis and of the resulting debt-to-adjusted EBITDA (TTM) ratio:
