The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

Filing Explained

SGF retains two board-designation rights at a 10 percent ownership threshold, and the release reports completed note redemptions and repurchases.

This Form 8-K furnishes Diamondback’s third-quarter results and a stockholder letter; the letter says SGF retains two director-designation rights while it owns at least 10% of Diamondback’s outstanding stock.

The letter says SGF’s ownership fell below 25%, reducing its designation entitlement from four directors to two; it reports an 11-member board with two SGF designees.

The release reports completed debt actions: Diamondback redeemed all $698 million in 2026 Senior Notes at par on October 1 and repurchased $106 million principal of 2054 and 2064 notes during the quarter for $103 million, including accrued interest.

Adjusted EBITDA financial
"Adjusted EBITDA is a supplemental non-GAAP financial measure"
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
two-class method financial
"computed using the two-class method in accordance with GAAP"
Costless Collars financial
"Costless Collars - Henry Hub"
A costless collar is a hedging strategy where an investor buys a protective option that limits losses and simultaneously sells an option that caps gains so the two premiums roughly cancel out. Think of it like buying insurance on a car while agreeing to share any big windfall from its sale with the insurer — it protects your downside without an upfront payment, but it also limits how much you can profit. Investors use it to reduce risk on a position while preserving capital and avoiding immediate cash outlay.
Basis Swaps technical
"Basis Swaps - WTI (Midland)"
A basis swap is a contract where two parties exchange streams of interest payments that are tied to different variable interest benchmarks, so each side pays one floating rate and receives another. It matters to investors because it helps manage the cost and risk that arise when assets, liabilities or contracts use different interest measures—think of it like trading two adjustable-rate bills to match what you owe with what you get paid, helping stabilize cash flows and hedge valuation or funding mismatches.

markets; regional supply and demand factors, including delays, curtailments or interruptions of production, or governmental orders, rules or regulations that impose production limits; federal and state legislative and regulatory initiatives relating to hydraulic fracturing, including the effect of existing and future laws and governmental regulations; physical and transition risks relating to climate change, changing political and social perspectives on climate change and other environmental, social and governance factors, and risks from our publicly disclosed targets related to sustainability and emissions reduction initiatives; challenges in developing our existing leasehold acreage and finding, developing or acquiring additional reserves; restrictions on the use of water, including limits on the use of produced water and a moratorium on new produced water disposal well permits recently imposed by the Texas Railroad Commission in an effort to control induced seismicity in the Permian Basin; significant declines in prices for oil, natural gas, or natural gas liquids, which could require recognition of significant impairment charges; conditions in the capital, financial and credit markets, including the availability and pricing of capital for acquisitions, exploration and development operations; challenges with employee retention and an increasingly competitive labor market; changes in availability or cost of rigs, equipment, raw materials, supplies and oilfield services; changes in safety, health, environmental, tax and other regulations or requirements (including those addressing air emissions, water management, or the impact of global climate change); security threats, including cybersecurity threats and disruptions to our business and operations from breaches of our information technology systems, or from breaches of information technology systems of third parties with whom we transact business; lack of, or disruption in, access to adequate and reliable electrical power, internet and telecommunication infrastructure, information and computer systems, transportation, processing, storage and other facilities for our oil, natural gas and natural gas liquids; failures or delays in achieving expected reserve or production levels from existing and future oil and natural gas developments, including due to operating hazards, drilling risks, or the inherent uncertainties in predicting reserve and reservoir performance; inability to keep pace with technological developments in our industry; failure to meet our obligations under our oil purchase contracts; loss of one or more customers or their inability to meet their obligations; geographical concentration of our primary operations; risks from our return of capital activity, and uncertainties over our future dividends and share repurchases; difficulty in obtaining necessary approvals and permits; severe weather conditions and natural disasters; changes in the financial strength of counterparties to our credit facilities and hedging contracts; our substantial indebtedness and restrictions to our operating and financial flexibility; changes in our credit rating; failure to identify, complete and successfully integrate acquisitions, including Viper’s Riverbend acquisition, Viper's McElroy Ranch acquisition and Viper’s Sitio acquisition; the Endeavor stockholders’ ability to significantly influence our business and potential conflicts of interest; and other risks described in Part I, Item 1A of Diamondback’s Annual Report on Form 10-K, filed with the SEC on February 25, 2026, and those risks disclosed in its subsequent filings on Forms 10-K, 10-Q and 8-K, which can be obtained free of charge on the SEC’s website at http://www.sec.gov and Diamondback’s website at www.diamondbackenergy.com/investors.

In light of these factors, the events anticipated by Diamondback’s forward-looking statements may not occur at the time anticipated or at all. Moreover, Diamondback operates in a very competitive and rapidly changing environment and new risks emerge from time to time. Diamondback cannot predict all risks, nor can it assess the impact of all factors on its business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those anticipated by any forward-looking statements it may make. Accordingly, you should not place undue reliance on any forward-looking statements. All forward-looking statements speak only as of the date of this release or, if earlier, as of the date they were made. Diamondback does not intend to, and disclaims any obligation to, update or revise any forward-looking statements unless required by applicable law.

NON-GAAP FINANCIAL MEASURES

ADJUSTED EBITDA

Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. The Company defines Adjusted EBITDA as net income (loss) attributable to Diamondback Energy, Inc., plus net income (loss) attributable to non-controlling interest ("net income (loss)") before non-cash (gain) loss on derivative instruments, net, interest expense, net, depreciation, depletion, amortization and accretion, depreciation and interest expense related to equity method investments, (gain) loss on extinguishment of debt, impairment of oil and natural gas properties, non-cash equity-based compensation expense, capitalized equity-based compensation expense, other non-cash transactions and provision for (benefit from) income taxes. Adjusted EBITDA is not a measure of net income as determined by United States generally accepted accounting principles ("GAAP"). Management believes Adjusted EBITDA is useful because the measure allows it to evaluate the Company’s operating performance and compare the results of its operations from period to period without regard to its financing methods or capital structure. The Company excludes the items listed above from net income (loss) to determine Adjusted EBITDA because these amounts can vary substantially from company to company within its industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Further, the Company excludes the effects of significant transactions that may affect earnings but are unpredictable in nature, timing and amount, although they may recur in different reporting periods. Adjusted EBITDA should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP or as an indicator of the Company’s operating performance. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic costs of depreciable assets. The Company’s computation of Adjusted EBITDA may not be comparable to other similarly titled measures of other companies or to such measure in our credit facility or any of our other contracts.

ADJUSTED NET INCOME
Adjusted net income is a non-GAAP financial measure equal to net income (loss) attributable to Diamondback Energy, Inc. plus net income (loss) attributable to non-controlling interest ("net income (loss)") adjusted for non-cash (gain) loss on derivative instruments, net, (gain) loss on extinguishment of debt, other non-cash transactions and related income tax adjustments. The Company’s computation of adjusted net income may not be comparable to other similarly titled measures of other companies or to such measure in our credit facility or any of our other contracts. Management believes adjusted net income helps investors in the oil and natural gas industry to measure and compare the Company's performance to other oil and natural gas companies by excluding from the calculation items that can vary significantly from company to company depending upon accounting methods, the book value of assets and other non-operational factors. Further, in order to allow investors to compare the Company's performance across periods, the Company excludes the effects of significant transactions that may affect earnings but are unpredictable in nature, timing and amount, although they may recur in different reporting periods.

The two-class method is an earnings allocation which reflects the respective ownership among holders of common stock and participating securities. Diluted earnings per share using the two-class method is calculated as (i) net income attributable to Diamondback Energy, Inc., (ii) less the reallocation of $9 million in earnings attributable to participating securities, (iii) divided by diluted weighted average common shares outstanding for the respective periods.




OPERATING CASH FLOW BEFORE WORKING CAPITAL CHANGES, FREE CASH FLOW AND ADJUSTED FREE CASH FLOW

Operating cash flow before working capital changes, which is a non-GAAP financial measure, represents net cash provided by operating activities as determined under GAAP without regard to changes in working capital. The Company believes operating cash flow before working capital changes is a useful measure of an oil and natural gas company’s ability to generate cash used to fund exploration, development and acquisition activities and service debt or pay dividends. The Company also uses this measure because changes in working capital relate to the timing of cash receipts and disbursements that the Company may not control and may not relate to the period in which the operating activities occurred. This allows the Company to compare its operating performance with that of other companies without regard to financing methods and capital structure.

The Company defines Free Cash Flow, which is a non-GAAP financial measure, as cash flow from operating activities before changes in working capital in excess of cash capital expenditures. The Company defines Adjusted Free Cash Flow, which is a non-GAAP financial measure, as Free Cash Flow before the tax impact from divestitures (if any), merger and transaction expenses, costs of early termination of derivatives and settlements of any treasury locks (if any). The Company believes that Free Cash Flow and Adjusted Free Cash Flow are useful to investors as they provide a measure to compare both cash flow from operating activities and additions to oil and natural gas properties across periods on a consistent basis, adjusted, as applicable, for non-recurring impacts from divestitures, merger and transaction expenses, the early termination of derivative contracts and settlements of treasury locks. These measures should not be considered as an alternative to, or more meaningful than, net cash provided by operating activities as an indicator of liquidity. The Company's computation of Free Cash Flow may not be comparable to other similarly titled measures of other companies.

NET DEBT

The Company defines the non-GAAP measure of net debt as total debt (excluding debt issuance costs, discounts, premiums and unamortized basis adjustments) less cash and cash equivalents and restricted cash that has been irrevocably deposited for the redemption of principal amounts of outstanding senior notes. Net debt should not be considered an alternative to, or more meaningful than, total debt, the most directly comparable GAAP measure. Management uses net debt to determine the Company's outstanding debt obligations that would not be readily satisfied by its cash and cash equivalents on hand. The Company believes this metric is useful to analysts and investors in determining the Company's leverage position because the Company has the ability to, and may decide to, use a portion of its cash and cash equivalents to reduce debt.

LETTER TO STOCKHOLDERS ISSUED BY DIAMONDBACK ENERGY, INC.

Midland, TX (November 2, 2026)

Diamondback Stockholders,

This letter is meant to be a supplement to our earnings release and is being furnished to the Securities and Exchange Commission (SEC) and released to our stockholders simultaneously with our earnings release. Please see the information regarding forward-looking statements and non-GAAP financial information included at the end of this letter.

Mega Themes

Before we talk about the quarter, we would like to give you some insight into what we see as the mega-themes of the Permian Basin over the next decade, Diamondback’s potential role in those mega-themes and why our strategy will benefit Diamondback stockholders. In our mind, these three mega-themes are: increased recoveries of oil in place, gas production growth and monetization through LNG and power demand and the growing AI / power / infrastructure buildout in West Texas and the Permian Basin.

The past decade in the Permian Basin was dominated by capital efficiency improvements, resource expansion and consolidation. This resulted in more assets in the hands of larger, well-run operators turning the dream of the shale revolution into a reality, producing more consistent returns on and of capital to the stockholders that helped fund it.

While we expect to maintain consistent returns, we anticipate the next decade will look different. Upstream consolidation in the Permian will continue, albeit at a more measured pace given how much has already occurred to date. Capital efficiency will continue to improve, but the pace of above ground mechanical improvements will naturally slow relative to what has been accomplished over the last ten years. Resource expansion will continue and new zones like the Barnett and Woodford (more on that later) are exciting, but it will be tough to match the resource growth we saw from developing the Wolfcamp B as a standalone horizontal bench in 2012 in the Midland Basin to the 8+ zones we are developing today.

Therefore, we will need to do more with what we have, directly and indirectly. We will continue to improve our position by increasing working interest (and mineral interest at Viper Energy, Inc. (“Viper”), our consolidated mineral and royalty subsidiary), extending laterals through trades, grinding down costs and being prepared for M&A opportunities if or when they present themselves.




As we mentioned earlier, we are also working on being at the forefront of three Permian mega-themes:

1. Improving Recoveries

We currently estimate that we extract approximately 10% of the oil in place in the Permian Basin today. Every percentage point of incremental recovery carries significant value to our stockholders, and we are therefore very focused on improving recoveries. There are several factors that contribute to the ultimate recovery of hydrocarbons from a well, but the list below represents the main factors we are focused on.

a) Development design:
Each project Diamondback executes is designed to maximize the return the Company receives on capital while ensuring resource recovery is maximized at an appropriate incremental rate of return hurdle. Our philosophy has resulted in Diamondback's projects generating the highest average returns relative to our peer group. These outcomes are clearly seen on slide #10 of this quarter’s investor presentation.

Broadly, our relatively higher wells per section × better per well performance ÷ the lowest cost structure in the basin = the maximum return for every dollar of capital invested. Diamondback was an early adopter of co-development in the Midland Basin, moving to this methodology in 2019 for the core zones from the Middle Spraberry to the Wolfcamp B. Co-development of 8+ benches in the Midland Basin, optimized spacing and targeting, longer laterals and creative wellbore trajectories allow us to optimize our developments while preserving the value of our remaining inventory – an advantage we believe is unmatched in the basin.

b) Completion design:
Proper completion sizing is imperative to maximizing value from each development project. The advancement of completion technology into simulfrac and continuous pumping are positive cost stories from an operational standpoint, but they have also allowed us to pursue more aggressive stage designs with tighter cluster and stage spacing to increase reservoir contact and near-wellbore fracture complexity. We believe this, combined with our efforts around advanced chemical additives, is contributing to recent well outperformance relative to previous vintages seen on slide #10 of this quarter’s investor presentation.

c) Enhanced Oil Recovery (“EOR”):
Chemical EOR has the potential to meaningfully improve recovery factors and shallow base decline rates in unconventional reservoirs. Shallowing our corporate base decline by just 1% at current capital efficiency implies drilling 10 to 15 fewer wells to maintain flat oil production, extending inventory quality and duration.

Chemical EOR makes it easier for oil to flow through the reservoir to the wellbore. We have several ongoing pilots testing various surfactant designs both in the remedial and completion phases of our operations. These pilots are in the early stages, and we have seen a wide range of outcomes from our initial tests. We will continue to learn from these tests and refine our methodologies to continuously improve, just as we did on the completion side of the business over the last fifteen years.

Our goal is and has always been to be the best at converting rock into cash flow. We have demonstrated this ability consistently over the past decade and will continue to do so moving forward. We are confident the technologies and workflows we are developing today will propel us to higher recoveries in the future and we look forward to keeping our stockholders updated on our progress.




2. Gas Production and Monetization

In the third quarter, future gas growth out of the Permian Basin received significant attention as a WhiteWater-led consortium (that includes Diamondback) reached Final Investment Decision (“FID”) on another large diameter pipeline out of the basin. This pipe is called Solitude and is set to enter service in the second half of 2029. This project consists of two twin 48" lines able to move 4.5 bcf/d out of the Permian to Katy and Gulf Coast markets, with potential to expand to 7.5 bcf/d. While the market was surprised that another pipe reached FID this quickly after multiple announcements over the last 18 months, we were not.

As we have said many times, the Permian Basin has not tried to produce gas yet. We expect the Permian to be the largest natural gas play as well as the largest oil play in the United States in the 2030s. Gas to oil ratios will naturally continue to expand, secondary zones in both the Midland and the Delaware Basins are gassier than what operators have targeted to date and there are gas-weighted exploratory zones that have not even been tested yet given the perpetual egress issues out of this basin.

As for Diamondback’s strategy, our goal is to continue to control more of our gas further downstream to a mix of end markets, primarily feeding the Gulf Coast LNG complex. We are working to build relationships with LNG players who are long offtake and short physical molecules. There should be beneficial deals to get done with those companies in the coming years. We also believe in-basin and in-state power demand will continue to grow, driven by both behind-the-meter power development and the expansion of the Texas grid.

At the highest level, the gas theme in the Permian Basin has moved from supply-push to demand-pull, which should be beneficial to the owners of the molecule long-term and therefore Diamondback stockholders.

3. West Texas AI / Power / Infrastructure Buildout

We believe that the incremental large-scale data center development in the United States should go through West Texas and that Diamondback can be an integral part of that value chain without overstepping our core competencies. In our mind, our Company owns or has access to all the key components of data center development:
•Fuel: We have significant natural gas reserves that we control. These can grow if needed.
•Land: We own surface in areas conducive to development and know how to strategically grow our position.
•Water: We are invested in and understand the water business, which is vital to our upstream business and becoming increasingly important as industrial use cases including data center and power cooling needs grow.
•Deal Execution: We have a long track record of sourcing, structuring, financing and integrating transactions across our value chain. Since our 2012 IPO, Diamondback, along with Viper, have successfully completed approximately $60 billion in trades across dozens of transactions, and in parallel, have formed, scaled and successfully exited joint ventures in midstream and water infrastructure, creating value beyond the drillbit. In short, we know how to get deals done, upstream and non-upstream alike, that benefit our stockholders.




Therefore, we believe companies like Diamondback with credible projects will continue to rise to the top. Our hope is to build relationships and partnerships across this space that put us in the middle of the AI revolution, and we think a company like ours can add significant value to advancing this mega-theme.

We have already developed significant relationships with strong, reliable partners in working our first project. We expect these partnerships to grow, but also see room for more. West Texas has a significant amount of private land, an abundance of fuel for power and our industry (Diamondback in particular) knows how to build things with unmatched efficiency. Diamondback’s own production has grown more than 330x since 2012 – a growth rate competitive with the tech industry that is naturally intersecting with ours.

Barnett / Woodford Update

We received significant market curiosity after revealing our Barnett position in the Midland Basin earlier this year. Since that announcement, we have grown our position to 224,000 net acres, up 12% since February. We are also entering a period of increased activity in the play as we move to full-field development so we can maximize capital efficiency while honoring lease obligations.

When we revealed our position, we told our investors we needed to work the well costs down to $800 per lateral foot for the play to be competitive with our core program. We are on our way to this number, with drilling costs down over 10% per lateral foot year-to-date including a recent well below $350 per lateral foot. Completion costs have also been reduced to below $400 per lateral foot as we have moved to large pad simulfrac operations on most current and future Barnett projects.

Recent well results also continue to increase our excitement about the Barnett. Today we revealed data around our best wells in the play on slide #11 of this quarter’s investor presentation, which had previously remained private as we worked through our leasing program. This performance, combined with our improving cost structure, further strengthens our conviction in this emerging opportunity.

Governance

In September, we disclosed an agreement with our largest stockholder, SGF FANG Holdings, LP (“SGF”), to revise the stepdown thresholds for SGF’s board designation rights. In connection with SGF’s most recent stock sale that reduced its ownership below 25% and reduced its corresponding right to designate board members from four board members to two board members, we essentially agreed that SGF could continue to designate two board members for so long as it owns at least 10% of our outstanding stock.

The Diamondback Board now has 11 members, in line with S&P 500 and large-cap energy peer averages. We believe this size balances breadth of expertise with cohesion. While we have two Board members who are SGF designees and nine who are not, we feel we are one Diamondback Board with a unified strategy to drive stockholder value while ensuring our largest stockholder feels appropriately represented on the Board with two well-qualified members who collectively bring over 75 years of experience in the oil and gas industry. We believe this is best-in-class governance.




Macro Update

The macro backdrop is almost exactly as we described last quarter: highly volatile and impossible to predict. The timing of the eventual global oil supply normalization is anyone’s guess, and we therefore expect the current volatility to continue. Through this volatility, our priorities remain unchanged: execute with the best capital efficiency in the industry and allocate Free Cash Flow appropriately to maximize long-term stockholder value.

Third Quarter 2026 Operational Performance

Third quarter oil production averaged 525 MBO/d, flat with the second quarter and above the midpoint of our guidance range. Total production for the quarter averaged 1,034 MBOE/d, up 2% quarter over quarter. Third quarter cash capital expenditures were $1.03 billion, within our $950 million to $1.05 billion guidance range. With one quarter remaining, we have updated our full-year 2026 oil production guidance to ~524 MBO/d, total production guidance to ~1,015 MBOE/d; and our full-year capex guidance to approximately $3.95 billion to $4.00 billion.

Fourth quarter guidance is 518 to 528 MBO/d (1,025 to 1,045 MBOE/d) on $1.00 to $1.05 billion of capex. Our current expectation for activity in 2027 is to run five electric simulfrac fleets consistently for maximum efficiency while running enough rigs ahead of those crews to maintain the execution buffers one would expect from Diamondback.

On the drilling side, our blended cost per lateral foot rose in the quarter as the program shifted toward deeper Barnett and Wolfcamp D targets, which now make up roughly a fifth of the wells we drill. On a like-for-like basis, drilling costs per foot in each formation remain flat to lower than a year ago. In total, we drilled 105 gross wells and completed 135, with average completed lateral length up roughly 13% quarter over quarter to 13,584 feet per well. Our completion crews finished 1.86 million lateral feet, 10% more than last quarter, at a cost per lateral foot essentially flat with both the prior quarter and a year ago. These results absorbed higher diesel, sand and water costs, consistent with the inflation pressure we flagged last quarter in casing, fuel and fuel-adjacent items. Service pricing outside those categories has remained largely stable, but it is logical that inflation could build if oil prices stay in the triple digits and the Permian rig count keeps rising. We expect any increase to be more modest than the 2022 upcycle, when rig activity surged while supply chains were still recovering from the pandemic. We continue to challenge our teams to offset cost pressure with efficiency gains in the field; we expect those gains to materialize, but the net effect will depend on the macro environment.

Technology is increasingly part of how we deliver these results. Artificial intelligence continues to grow in importance to our daily operations. We now have ~500 plunger-lift wells, about a third of our current count, that run autonomously, and we expect to convert the remainder in short order. We are also in the early stages of integrating drones into our field operations where the drones can identify issues ahead of human interaction, improving human efficiency and reducing corporate downtime.

These gains are visible in our unit costs. Lease operating expense was $5.97 per BOE, flat with the second quarter and roughly 4% below the first quarter, and total cash operating expense was $10.91 per BOE, down slightly from $10.96 in the second quarter and about 3% below the first quarter. Behind those numbers is a production organization doing more work at lower unit cost: our well-maintenance teams completed 1,448 jobs, 19% more than in the second quarter, at an average cost per job roughly 10% lower. Additionally, electric submersible pump repair costs are 14% less on average. Keeping downtime and the workover backlog in check as our well count grows is what is holding lifting cost down.




Third Quarter 2026 Financial Performance

We generated $2.6 billion in net cash provided by operating activities in the third quarter, which translated to $2.1 billion of Free Cash Flow. Cash capital expenditures of $1.0 billion represented 39% of net cash provided by operating activities for the quarter and 37% year to date. Our corporate reinvestment ratio (defined as cash CAPEX divided by Operating Cash Flow Before Working Capital Changes) was 32% for both the quarter and year to date, meaning two of every three dollars of cash flow we generated this year have been converted to Free Cash Flow.

Since the Endeavor merger closed eight quarters ago, oil production per share has increased every quarter and is up 15% over that span. Year over year, oil production per share has grown 7.5% on absolute oil growth of 4%. Year over year, net cash provided by operating activities per share has grown 12.5%, and Free Cash Flow per share has grown 26%, with our diluted share count down 3%.

Capital Allocation

Earlier this year, we removed our commitment to return a minimum amount of Free Cash Flow on a quarterly basis to stockholders. Since then, we have focused on taking advantage of what the market gives us. We have repurchased $1.1 billion of notional bonds outstanding for ~$970 million (including accrued interest) this year. It is rare for an E&P to be able to do this pro-cyclically. On top of that, in 2026 through September 30, we have reduced total debt at Diamondback (excluding Viper) by approximately $1.5 billion, to $11.0 billion, and net debt at Diamondback by approximately $2.0 billion. On a consolidated basis, total debt has decreased approximately $1.3 billion and net debt approximately $1.7 billion this year through September 30.

"Ground game" has been a hot topic in the Permian Basin this year, and Diamondback has always prided itself on executing deals of all sizes. Year to date, we have executed 34 acquisitions for $406 million, adding over 28,000 net acres and 95 net locations, and closed 10 trades covering more than 20,000 net acres. While each deal is small relative to our enterprise, in aggregate they matter: this year's ground game activity has added 1.9 million lateral feet to inventory, replacing roughly a full quarter's worth of completed footage. Every one of these deals creates value for our stockholders through higher working interest, longer laterals and extended inventory duration – little wins that add up year in and year out.

We also saw periods of stock price weakness in the third and early fourth quarters, and we took advantage of this weakness and bought back 1.7 million shares at an average price of $186.11. As we continue to generate cash flow at what we believe are above mid-cycle commodity prices, the “top” that we use to ensure we buy back stock at an accretive value relative to mid-cycle commodity pricing and our cost of capital will continue to go up – accreting value to the stockholders long-term. On the other hand, we are also preparing our balance sheet to be able to be aggressive on stock repurchases at the appropriate time of the natural commodity cycle.

Lastly, today we announced we increased our base dividend by over 7% to $4.72 per share annually from $4.40 previously. As a reminder, base dividend growth remains a core tenet of the value proposition at Diamondback and our base dividend is now up over 9x since initiating at $0.50 per share in 2018.




In closing, we continue to execute exceptionally well on the base business. This execution and the trust we have in our team frees us up to think more strategically about the future of the Permian Basin and Diamondback’s role in that future. We gave you a glimpse into that thinking today, see exciting things on the horizon and will update our stockholders as we progress on these initiatives with the transparency you should continue to expect from us.

Thank you for your continued interest in Diamondback Energy.

Sincerely,

Kaes Van't Hof
Chief Executive Officer and Director

(“Viper”), Viper’s Riverbend acquisition, Viper’s McElroy Ranch acquisition and Viper’s Sitio acquisition, and other acquisitions, divestitures or reorganizations); and plans and objectives of management (including plans for future cash flow from operations and for executing environmental strategies) are forward-looking statements. When used in this letter, the words “aim,” “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “future,” “guidance,” “intend,” “may,” “model,” “outlook,” “plan,” “positioned,” “potential,” “predict,” “project,” “seek,” “should,” “target,” “will,” “would,” and similar expressions (including the negative of such terms) as they relate to Diamondback are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. Although Diamondback believes that the expectations and assumptions reflected in its forward-looking statements are reasonable as and when made, they involve risks and uncertainties that are difficult to predict and, in many cases, beyond Diamondback’s control. Accordingly, forward-looking statements are not guarantees of future performance and Diamondback’s actual outcomes could differ materially from what Diamondback has expressed in its forward-looking statements.

Factors that could cause the outcomes to differ materially include (but are not limited to) the following: geopolitics and market conditions, including changes in supply and demand levels for oil, natural gas and natural gas liquids and the resulting impact on the price for those commodities; changes in U.S. energy, environmental, monetary and trade policies, including with respect to tariffs or other trade barriers and any resulting trade tensions; actions taken by the members of OPEC and its non-OPEC allies (OPEC+) affecting the production and pricing of oil, as well as other domestic and global political, economic, or diplomatic developments; changes in general economic, business or industry conditions, including changes in foreign currency exchange rates, interest rates, inflation rates, and instability in the financial sector; regional supply and demand factors, including delays, curtailments or interruptions of production, or governmental orders, rules or regulations that impose production limits; federal and state legislative and regulatory initiatives relating to hydraulic fracturing, including the effect of existing and future laws and governmental regulations; physical and transition risks relating to climate change, changing political and social perspectives on climate change and other environmental, social and governance factors, and risks from our publicly disclosed targets related to sustainability and emissions reduction initiatives; challenges in developing our existing leasehold acreage and finding, developing or acquiring additional reserves; restrictions on the use of water, including limits on the use of produced water and a moratorium on new produced water disposal well permits recently imposed by the Texas Railroad Commission in an effort to control induced seismicity in the Permian Basin; significant declines in prices for oil, natural gas, or natural gas liquids, which could require recognition of significant impairment charges; conditions in the capital, financial and credit markets, including the availability and pricing of capital for acquisitions, exploration and development operations; challenges with employee retention and an increasingly competitive labor market; changes in availability or cost of rigs, equipment, raw materials, supplies and oilfield services; changes in safety, health, environmental, tax and other regulations or requirements (including those addressing air emissions, water management, or the impact of global climate change); security threats, including cybersecurity threats and disruptions to our business and operations from breaches of our information technology systems, or from breaches of information technology systems of third parties with whom we transact business; lack of, or disruption in, access to adequate and reliable



electrical power, internet and telecommunication infrastructure, information and computer systems, transportation, processing, storage and other facilities for our oil, natural gas and natural gas liquids; failures or delays in achieving expected reserve or production levels from existing and future oil and natural gas developments, including due to operating hazards, drilling risks, or the inherent uncertainties in predicting reserve and reservoir performance; inability to keep pace with technological developments in our industry; failure to meet our obligations under our oil purchase contracts; loss of one or more customers or their inability to meet their obligations; geographical concentration of our primary operations; risks from our return of capital activity, and uncertainties over our future dividends and share repurchases; difficulty in obtaining necessary approvals and permits; severe weather conditions and natural disasters; changes in the financial strength of counterparties to our credit facilities and hedging contracts; our substantial indebtedness and restrictions to our operating and financial flexibility; changes in our credit rating; failure to identify, complete and successfully integrate acquisitions, including Viper’s Riverbend acquisition, McElroy Ranch acquisition and Sitio acquisition; the Endeavor stockholders’ ability to significantly influence our business and potential conflicts of interest; and other risks described in Part I, Item 1A of Diamondback’s Annual Report on Form 10-K, filed with the SEC on February 25, 2026, and those risks disclosed in its subsequent filings on Forms 10-Q and 8-K, which can be obtained free of charge on the SEC’s website at http://www.sec.gov and Diamondback’s website at www.diamondbackenergy.com/investors.

In light of these factors, the events anticipated by Diamondback’s forward-looking statements may not occur at the time anticipated or at all. Moreover, Diamondback operates in a very competitive and rapidly changing environment and new risks emerge from time to time. Diamondback cannot predict all risks, nor can it assess the impact of all factors on its business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those anticipated by any forward-looking statements it may make. Accordingly, you should not place undue reliance on any forward-looking statements. All forward-looking statements speak only as of the date of this letter or, if earlier, as of the date they were made. Diamondback does not intend to, and disclaims any obligation to, update or revise any forward-looking statements unless required by applicable law.

Non-GAAP Financial Measures

This letter includes financial information not prepared in conformity with generally accepted accounting principles (GAAP), such as Free Cash Flow, Free Cash Flow per share, Operating Cash Flow Before Working Capital Changes, and net debt. The non-GAAP information should be considered by the reader in addition to, but not instead of, financial information prepared in accordance with GAAP. A reconciliation of the differences between these non-GAAP financial measures and the most directly comparable GAAP financial measures can be found in Diamondback's quarterly results, which are posted on Diamondback's website at www.diamondbackenergy.com/investors and included as Exhibit 99.1 to the Current Report on Form 8-K filed by Diamondback with the SEC that also includes this letter as Exhibit 99.2. Furthermore, this letter includes or references certain forward-looking, non-GAAP financial measures. Because Diamondback provides these measures on a forward-looking basis, it cannot reliably or reasonably predict certain of the necessary components of the most directly comparable forward-looking GAAP financial measures, such as future impairments and future changes in working capital. Accordingly, Diamondback is unable to present a quantitative reconciliation of such forward-looking, non-GAAP financial measures to the respective most directly comparable forward-looking GAAP financial measures. Diamondback believes that these forward-looking, non-GAAP measures may be a useful tool for the investment community in comparing Diamondback's forecasted financial performance to the forecasted financial performance of other companies in the industry.
