About Diamondback Energy, Inc.

Diamondback Energy, Inc. (ticker: FANG) is an independent oil and natural gas company listed in the United States on the NASDAQ market, with corporate headquarters in Midland, Texas. For French, Belgian and Swiss investors, the company is best understood as a highly concentrated Permian Basin upstream producer, focused almost entirely on unconventional onshore oil and gas development in one of North America’s most productive hydrocarbon provinces. Diamondback’s business model has been built through a combination of organic development and acquisitions; company filings indicate operating origins in 2007, and the strategy has consistently centered on acquiring, developing, exploring and exploiting long-life shale and tight-oil assets in West Texas and New Mexico. Diamondback’s core operations are upstream, meaning the company primarily drills for and produces crude oil and natural gas rather than running a diversified global energy portfolio. That focus gives management a clear operating framework: high-return drilling inventory, capital discipline, efficient well execution, and strong free cash flow generation. The company has also maintained midstream exposure through dedicated infrastructure and partnership structures, helping support gathering, transport, water handling and other logistics needed to move production to market. In practical terms, this means Diamondback is not just a producer of oil and gas, but also a basin-focused operator with associated infrastructure economics tied to the Midland and Delaware Basins. From a competitive standpoint, Diamondback is one of the better-known large independents in the Permian Basin. Its competitive advantages typically come from scale in a premium basin, a concentrated operating footprint, and the ability to pair production growth with shareholder returns. The company has also expanded materially through major transactions, including Energen, Endeavor Energy Resources and Double Eagle, which strengthened its acreage position and reinforced its standing among leading Permian operators. That said, the company remains highly exposed to commodity prices and to operational execution in a single geographic region, which is important for investors to consider. Recent developments have been constructive. In February 2026, Diamondback reported full-year 2025 results that showed average production of about 921.0 MBOE/d, strong operating cash flow and substantial free cash flow. The company also increased its base dividend and continued a large share repurchase program, underlining a capital-return oriented strategy. Diamondback has additionally continued portfolio optimization through non-core asset sales and through the growth of its Viper Energy subsidiary. For international investors, FANG represents a classic U.S. energy cash-flow story: a Permian-led producer with significant scale, strong shareholder-return policies, and earnings sensitivity tied to oil prices and basin execution.
