Diamondback Q2 2026 earnings: Oil prices and production lift cash flow

Diamondback Energy (NASDAQ: FANG) reported Q2 2026 revenue of $5.56 billion, up approximately 51% from $3.68 billion a year earlier, while diluted EPS rose to $6.65 from $2.38. Net cash provided by operating activities reached $3.59 billion and company-defined free cash flow was $2.33 billion, supported by higher oil prices and production of more than 1.0 million BOE per day. Diamondback also raised its full-year production outlook without increasing its approximately $3.9 billion capital budget.

Core earnings data

Oil, natural gas and natural gas liquids sales increased approximately 44% to $4.79 billion. Purchased-oil sales also rose to $739 million from $335 million, but the corresponding purchased-oil expense was $730 million, meaning this activity contributed little operating profit relative to its effect on reported revenue.

Total costs and expenses increased approximately 20%, well below the 51% increase in revenue. As a result, operating income more than doubled and the operating margin expanded to approximately 45.2%. Adjusted net income attributable to Diamondback was $1.83 billion, adjusted diluted EPS was $6.48, and adjusted EBITDA attributable to the company was $3.55 billion.

Free cash flow is a non-GAAP measure defined by Diamondback as operating cash flow before working-capital changes minus cash capital expenditures.

Higher oil realizations and volumes outweighed negative gas prices

Average total production increased approximately 10.6% to 1.018 million BOE per day, surpassing the one-million-BOE threshold. Average oil production rose approximately 6% to 525,176 barrels per day.

Pricing had an even larger effect. Diamondback’s realized oil price increased approximately 53% to $96.82 per barrel, while its combined realized price rose approximately 30% to $51.68 per BOE. By contrast, the realized natural gas price fell to negative $2.15 per Mcf from positive $0.88, demonstrating a sharp divergence between oil and gas economics during the quarter.

Hedges moderated both sides of that divergence. The hedged oil price was $94.33 per barrel, below the unhedged realization, while the hedged natural gas price improved to negative $0.34 per Mcf. Overall, the hedged combined realization of $52.90 per BOE remained above the unhedged figure.

Profitability, cash flow and the balance sheet

Average cash operating expense increased to $10.96 per BOE from $10.10 a year earlier, although it declined from $11.26 in Q1 2026. Lease operating expense and production and ad valorem taxes increased year over year, while gathering, processing and transportation expense fell to $1.22 per BOE from $1.73.

GAAP operating cash flow of $3.59 billion included a $263 million benefit from working-capital changes. Excluding those changes, operating cash flow was $3.33 billion; after $996 million of cash capital spending, Diamondback generated $2.33 billion of free cash flow.

Diamondback reduced consolidated total debt by approximately $1.30 billion from the prior quarter to $12.77 billion. Net debt declined by approximately $1.59 billion to $12.30 billion. The company had $462 million of consolidated cash and cash equivalents, while standalone liquidity was $3.39 billion, including $3.0 billion of available credit.

Capital returns continued alongside debt reduction. Diamondback repurchased 756,385 shares for $141 million during Q2 and declared a base dividend of $1.10 per share. The board subsequently doubled the repurchase authorization to $16.0 billion, with approximately $9.9 billion remaining as of July 31, 2026.

2026 guidance

Diamondback raised its minimum full-year production outlook while leaving planned capital expenditures unchanged. The combination points to higher expected output within the existing capital program, although the company also raised its expected cash tax rate.

Diamondback also expects Q3 cash taxes of $400 million to $460 million.

Risks investors need to watch

• Commodity-price exposure: Higher oil prices were a major earnings and cash-flow driver, while unhedged natural gas realizations were negative. A reversal in oil pricing or continued gas weakness could reduce revenue and cash generation.
• Unit-cost pressure: Cash operating expense remained above the prior-year level, with higher lease operating costs and production taxes partly offset by lower gathering and transportation expense.
• Higher cash taxes: The full-year cash tax-rate range increased to 19%-22%, and Q3 cash taxes are expected to be $400 million to $460 million, creating a direct call on cash flow.
• Production and capital execution: The raised production target assumes Diamondback can deliver at least 1.0 million BOE per day for 2026 while holding capital spending near $3.9 billion.
• Leverage: Debt declined materially during the quarter, but consolidated net debt remained $12.30 billion, leaving continued commodity-price and cash-flow sensitivity relevant to the balance sheet.

Summary

Diamondback’s Q2 2026 results reflected the combination of higher oil realizations, increased production and improved operating leverage, which more than offset negative natural gas pricing and higher year-over-year cash costs. Cash generation supported debt reduction and shareholder returns, while the higher production outlook with unchanged capital spending is the central item to monitor alongside oil prices, cash taxes and execution of the capital program.
