Rusty Hutson, Jr., CEO of Diversified, commented:

“Diversified continues to deliver consistent returns on our assets, along with the expansion of our asset portfolio, reinforcing our position as the U.S. PDP Champion. Our strong first-half performance reflects the resilience of our business model, the quality of our assets, and the dedication of our talented teams. With the successful integration of Maverick progressing on schedule, we are already realizing meaningful synergies and operational efficiencies that enhance our ability to optimize cash flow in our expanded portfolio and drive long-term value from our investments.

The strategic partnership with The Carlyle Group marks a transformational milestone for Diversified. This $2 billion commitment underscores confidence in our platform and provides significant capital flexibility to capitalize on the ongoing consolidation of mature producing assets. It also strengthens our ability to scale responsibly, in a non-dilutive manner, while preserving our disciplined approach to capital allocation.

We remain focused on unlocking value across our portfolio through asset optimization, which resulted in approximately $70 million of additional cash flow, high return projects with our targeted capital investments, and the continuation of portfolio optimization through Smarter Asset Management (SAM) programs. Our NextLVL team’s industry-leading pace of asset retirements and regulatory advancements in West Virginia highlights our commitment to collaborating across our organization and with key stakeholders to solidify our commitment to sustainable operations.

As we look ahead, the mega trends of electrification, AI power demand, and US LNG Export growth only strengthen the fundamental outlook for our business. The acceleration of natural gas generation for data center demand in Appalachia creates a line of sight to meaningful in-basin demand, pointing to tighter basis spreads near our footprint in the coming years. While our expansive central region operations are well-positioned to support US Energy dominance in the Gulf Coast, including as a strategic supplier to LNG export terminals.

Given Diversified's continued operational excellence, fundamental market tailwinds, and strategic actions to optimize our portfolio of assets, we remain confident in our ability to continue delivering consistent and resilient free cash flow, maintaining a strong balance sheet, and returning meaningful capital to shareholders. Diversified is well-positioned to thrive as a proven portfolio manager of energy assets in today’s evolving energy landscape, and we are proud to be the Right Company at the Right Time, delivering essential energy while creating long-term value for all stakeholders.”

Operations and Finance Update

Production

The Company recorded exit rate production in June 2025 of 1,135 MMcfepd (189 Mboepd)^(a) and delivered 2Q25 average net daily production of 1,149 MMcfepd (192 Mboepd). The Company's production volume mix was approximately 73% natural gas, 13% natural gas liquids ("NGL's"), and 14% oil, with approximately 64% of production volumes from the Central region and 36% from Appalachia for the second quarter. Net daily production for the quarter continued to benefit from Diversified’s peer-leading, shallow decline profile.

Margin and Total Cash Expenses per Unit

Diversified delivered 2Q25 per unit revenues of $4.88/Mcfe^(d) ($29.28/Boe) and Adjusted EBITDA Margin^(b) of 63% (65% unhedged). Notably, these per unit metrics reflect an increase in both revenues and expenses from the incorporation of greater liquids-related production of Maverick. The Company’s per unit expenses are anticipated to improve as the Company implements its playbook to achieve long-term, sustainable synergies and cost savings. For example, General and Administrative expenses compared to prior period levels, despite the higher per unit costs of Maverick, supporting our progress on cost savings and synergy capture.

Share Repurchase Program

At the 2025 Annual General Meeting, the Company's share repurchase authority was approved for a maximum of 8,099,015 shares representing 10% of the Company's issued share capital (the "2025 Authorization"). The Company announced details regarding the parameters of a Share Buyback Program (the "Program") on 20 March 2025, pursuant to which the maximum number of shares repurchased shall not exceed 4,756,842 Shares under the Program. Following the 2025 Authorization, the Company announces that the maximum number of shares repurchased under the Program shall be increased to, and shall not exceed, 8,099,015 shares. Year to date, the company has repurchased 3,273,466 shares, representing approximately 4% of the shares outstanding.

Combined Company 2025 Outlook

The Company is reiterating its previously announced Full Year 2025 guidance. Following the recently completed acquisition of Maverick, Diversified expects to realize significant operational synergies associated with a larger, consolidated position in Oklahoma and the ability to improve the overall cost structure of the Maverick assets while continuing to prioritize returns and Free Cash Flow generation.

The following outlook incorporates a nine-month contribution from the recently acquired Maverick assets.

Conference Call Details

The Company will host a conference call today, Monday, August 11, 2025, at 1:00 PM GMT (8:00 AM EDT) to discuss the 1H25 Interim Results and will make an audio replay of the event available shortly thereafter.

Use of Non-IFRS Measures

Certain key operating metrics that are not defined under IFRS (alternative performance measures) are included in this announcement. These non-IFRS measures are used by us to monitor the underlying business performance of the Company from period to period and to facilitate comparison with our peers. Since not all companies calculate these or other non-IFRS metrics in the same way, the manner in which we have chosen to calculate the non-IFRS metrics presented herein may not be compatible with similarly defined terms used by other companies. The non-IFRS metrics should not be considered in isolation of, or viewed as substitutes for, the financial information prepared in accordance with IFRS. Certain of the key operating metrics are based on information derived from our regularly maintained records and accounting and operating systems.

Adjusted EBITDA & Pro Forma TTM Adjusted EBITDA

As used herein, EBITDA represents earnings before interest, taxes, depletion, depreciation and amortization. Adjusted EBITDA includes adjusting for items that are not comparable period-over-period, namely, finance costs, accretion of asset retirement obligation, other (income) expense, (gain) loss on fair value adjustments of unsettled financial instruments, (gain) loss on natural gas and oil property and equipment, (gain) loss on sale of equity interest, unrealized (gain) loss on investment, costs associated with acquisitions, other adjusting costs, loss on early retirement of debt, non-cash equity compensation, (gain) loss on interest rate swaps, and items of a similar nature. Pro forma TTM adjusted EBITDA extends adjusted EBITDA by adjusting for acquisitions or other significant changes that impacted EBITDA over the last twelve months.

Adjusted EBITDA and pro form TTM adjusted EBITDA should not be considered in isolation or as a substitute for operating profit or loss, net income or loss, or cash flows provided by operating, investing and financing activities. However, we believe such measure is useful to an investor in evaluating our financial performance because it (1) is widely used by investors in the natural gas and oil industry as an indicator of underlying business performance; (2) helps investors to more meaningfully evaluate and compare the results of our operations from period to period by removing the often-volatile revenue impact of changes in the fair value of derivative instruments prior to settlement; (3) is used in the calculation of a key metric in one of our Credit Facility financial covenants; and (4) is used by us as a performance measure in determining executive compensation. When evaluating this measure, we believe investors also commonly find it useful to evaluate this metric as a percentage of our total revenue, inclusive of settled hedges, producing what we refer to as our adjusted EBITDA margin.

The following table presents a reconciliation of the IFRS Financial measure of Net Income (Loss) to Adjusted EBITDA for each of the periods listed:

Net Debt, Net Debt-to-Adjusted EBITDA & Net Debt-to-Pro Forma TTM Adjusted EBITDA

As used herein, net debt represents total debt as recognized on the balance sheet less cash and restricted cash. Total debt includes our borrowings under the Credit Facility, borrowings under or issuances of, as applicable, our subsidiaries’ securitization facilities, and other borrowings. We believe net debt is a useful indicator of our leverage and capital structure.

As used herein, net debt-to-adjusted EBITDA, net debt-to-pro forma TTM adjusted EBITDA, or “leverage” or “leverage ratio,” is measured as net debt divided by adjusted EBITDA or pro forma TTM adjusted EBITDA. We believe that this metric is a key measure of our financial liquidity and flexibility and is used in the calculation of a key metric in one of our Credit Facility financial covenants.

The following table presents a reconciliation of the IFRS Financial measure of Total Non-Current Borrowings to the Non-IFRS measure of Net Debt and a calculation of Net Debt-to-Adjusted EBITDA and Net Debt-to-Pro Forma Adjusted EBITDA for each of the periods listed:

Free Cash Flow

As used herein, free cash flow represents net cash provided by operating activities, less expenditures on natural gas and oil properties and equipment, and cash paid for interest. We believe that free cash flow is a useful indicator of our ability to generate cash that is available for activities beyond capital expenditures. The Directors believe that free cash flow provides investors with an important perspective on the cash available to service debt obligations, make strategic acquisitions and investments, and pay dividends.

The following table presents a reconciliation of the IFRS Financial measure of Net Cash from Operating Activities to the Non-IFRS measure of Free Cash Flow for each of the periods listed:

(1) Annualized second quarter 2025 free cash flow of $88 million and Market Cap of $1.1 billion as of August 8, 2025.

Total Revenue, Inclusive of Settled Hedges and Adjusted EBITDA Margin

As used herein, total revenue, inclusive of settled hedges, accounts for the impact of derivatives settled in cash. We believe that total revenue, inclusive of settled hedges, is useful because it enables investors to discern our realized revenue after adjusting for the settlement of derivative contracts.

As used herein, adjusted EBITDA margin is measured as adjusted EBITDA, as a percentage of total revenue, inclusive of settled hedges. Adjusted EBITDA margin encompasses the direct operating costs and the portion of general and administrative costs required to produce each Mcfe. This metric includes operating expense, employee costs, administrative costs and professional services, and recurring allowance for credit losses, which cover both fixed and variable cost components. We believe that adjusted EBITDA margin is a useful measure of our profitability and efficiency, as well as our earnings quality, because it evaluates the Group on a more comparable basis period-over-period, especially given our frequent involvement in transactions that are not comparable between periods.

The following table presents a reconciliation of the IFRS Financial measure of Total Revenue to the Non-IFRS measure of Total Revenue, Inclusive of Settled Hedges and a calculation of Adjusted EBITDA Margin for each of the periods listed:

(1) Net gain (loss) on commodity derivative settlements represents cash paid or received on commodity derivative contracts. This excludes settlements on foreign currency and interest rate derivatives, as well as the gain (loss) on fair value adjustments for unsettled financial instruments for each of the periods presented.
