Exhibit 99.1

Diversified Energy Response to Media Speculation

Diversified Energy Company (NYSE: DEC, LSE: DEC) (the “Company” or “Diversified”) notes recent media speculation regarding a potential transaction involving the Company.

Diversified has an acquisition strategy driven by discipline, focus, skill, and precision. The Company has made 35 acquisitions totaling over $7 billion of value since its IPO in 2017. Acquisitions are a core aspect of the Company’s strategy, and the Company regularly engages in preliminary discussions with potential counterparties in this regard.

The Company confirms that it has had preliminary discussions concerning a possible acquisition of Birch Resources. Discussions are ongoing and remain at an early stage. No agreement has been reached, and there is no certainty that any transaction will occur, nor as to the terms on which any transaction might proceed.

This announcement contains inside information for the purposes of Article 7 of the UK version of Regulation (EU) No. 596/2014 on Market Abuse (“UK MAR”), as it forms part of the UK domestic law by virtue of the European Union (Withdrawal) Act 2018.
