Diversified Energy Company has published its seventh annual sustainability report, giving investors a clearer view of how the business manages mature energy assets, environmental responsibilities and local economic impact.
The report, titled PROVEN: Stepping Up When Others Step Away, explains the company’s approach to acquiring and operating established energy assets.
The company presents asset stewardship as central to its strategy. Mature oil and gas assets can remain cash-generative, but they also carry risks around emissions, maintenance, regulation and eventual retirement. Diversified is using the report to show how it manages those risks as part of day-to-day operations.
Through its Next LVL Energy subsidiary, Diversified retired 486 wells in 2025. This included 388 company-owned wells and 98 third-party and orphan wells. Since the programme began, the company has retired more than 1,550 wells.
Companies operating mature assets need credible plans for end-of-life costs. Diversified’s disclosure gives the market more detail on how it is addressing those obligations and building operational capacity around them.
The report also highlights the Mountain State Plugging Fund, which Diversified describes as a first-of-its-kind well retirement fund. Structured funding for plugging activity can help reduce uncertainty around future liabilities and demonstrate a more planned approach to asset retirement.
Diversified Energy Company plc (LON:DEC, NYSE:DEC) is an independent energy company engaged in the production, marketing, transportation and retirement of primarily natural gas and natural gas liquids related to its U.S. onshore upstream and midstream assets.
