 Diversified Energy Company PLC

("Diversified" or the "Company")

Completion of Tapstone Acquisition

Diversified Energy Company PLC (LSE: DEC) is pleased to announce the closing of its acquisition of Oklahoma-based Tapstone Energy Holdings, LLC ("Tapstone") and Tapstone's interest in its related party KL CHK SPV, LLC (the "Acquisition"). The transaction, previously announced on 7 October, 2021, consists of certain upstream assets, field infrastructure, equipment and facilities. Oaktree Capital Management, L.P. ("Oaktree") completed its co-investment in the Acquisition.

Acquisition Highlights (Diversified's Interest)

•     Acquisition net purchase price of ~$181 million

•     Highly accretive 1.9x multiple, based on the net purchase price and ~$95 million of estimated next twelve months' ("NTM") Adjusted EBITDA^(a), before expected synergies

•     Current production of ~12 Mboepd (~72 MMcfepd) from ~660 net operated wells

◦     Production comprised of primarily natural gas and NGLs (~62% and 21%, respectively)

•     Net purchase price approximates a PV27 valuation at the effective date of 1 August 2021 with PDP reserves of ~35 MMBoe (~208 Bcfe) with pre-tax PV10 of ~$324 million^(b)

•     Producing asset's lower emissions intensity complements Diversified's emissions reduction strategy and positively impacts the Company's corporate emissions profile

•     Retained experienced Tapstone personnel to complement the continuity and consistency of operations and to facilitate the implementation of Smarter Asset Management opportunities

Diversified funded its portion of the Acquisition with a draw on the Company's enlarged $825 million Credit Facility, following its semi-annual redetermination completed on December 7, 2021. Post-transaction leverage, as measured by pro forma Net Debt to Hedged Adjusted EBITDA^(c), is  ~2.2x.

Commenting on the Acquisition and the enlarged borrowing base, CEO Rusty Hutson, Jr. said:

"Having closed our fourth acquisition within the Central Region this year, we begin the efficient integration process of these high-quality  assets. Alongside former Tapstone personnel who today join the Diversified family, we look forward to implementing our proven Smarter Asset Management programme and to leveraging our enlarged regional footprint to capture operational synergies. At less than two times Adjusted EBITDA, this highly accretive and attractively priced acquisition further solidifies our position as a leading consolidator of producing assets in the Central Region and enhances our cash flow to support our ESG initiatives, dividend distributions, debt reductions and further accretive reinvestment."
