    • Minimum of 35% of DCF: Allocated to cash dividends; Represents an approximate 5% yield based on 4Q 2023 Pro Forma DCF
    • Minimum of 30% of DCF: Allocated to additional cash dividends, share repurchases or a mix of both

4Q 2023 and 2H 2023 RESULTS RELATIVE TO 2H 2023 GUIDANCE

The table below shows fourth quarter 2023 and second half 2023 results relative to financial and operational guidance for the second half of 2023 that was issued on November 8, 2023.

Chris Conoscenti, Chief Executive Officer of Sitio commented, “In the fourth quarter, we continued to advance our strategic efforts through active portfolio management and returns-focused capital allocation. We are already off to a great start in 2024 as we entered into an agreement to acquire over 13,000 NRAs in the DJ Basin for a compelling price that is accretive for our shareholders. As we reallocate capital from the recently closed divestiture of assets in the Appalachia and Anadarko Basins into these higher returning assets, we will have transformed our current DJ Basin position into a leading position with enhanced exposure to the Greater Wattenberg Field. Additionally, I'm excited to announce that the Board of Directors has authorized a $200 million share repurchase program as part of our new return of capital framework, which provides us with another method to enhance long-term shareholder value. This repurchase program is a reflection of the confidence we have in the fundamentals of our business. We still plan to allocate at least 65% of DCF to return of capital and utilize the remainder of DCF to pay down debt and make opportunistic cash acquisitions. Under our updated return of capital framework, we intend to allocate a minimum of 35% of DCF to cash dividends and at least 30% of DCF to additional cash dividends, share repurchases or a mix of both.”

MERGERS AND ACQUISITIONS

On December 8, 2023, Sitio closed on the acquisition of 522 NRAs in the Permian Basin (the "4Q23 Stock Acquisition") in exchange for shares of its Class C Common Stock and OpCo Units. The acquired assets produced an average of approximately 46 Boe/d (62% oil) and generated approximately $0.2 million of asset level cash flow for the three months ended December 31, 2023 as if they were owned on October 1, 2023. The 4Q23 Stock Acquisition has an effective date of October 1, 2023 and 4Q 2023 cash flow attributable to the NRAs acquired is included in Sitio's 4Q 2023 Pro Forma DCF.

On December 22, 2023, Sitio closed on the divestiture of all of its mineral and royalty interests in the Anadarko Basin in Oklahoma and the Appalachian Basin in Pennsylvania, Ohio and West Virginia to an undisclosed third party for $114.0 million (the “Appalachian and Anadarko Basins Divestiture”).

In January of 2024, Sitio signed a definitive agreement to acquire 13,062 NRAs primarily in the core of the DJ Basin for $150.0 million, subject to customary closing adjustments. The transaction enhances the Company's DJ Basin footprint, adding high-quality acreage in the Greater Wattenberg Field at a compelling price with visible growth through the first half of 2025 from spuds, permits and acreage in several multi-year CAPs and OGDPs with leading operators such as Chevron Corporation, Occidental Petroleum, and Civitas Resources. Monthly net production on the DJ Basin Acquisition acreage has grown by 89% from December 2022 through December 2023, versus a 7% decline on the divested assets over the same time period. As of December 31, 2023, the DJ Basin Acquisition assets had approximately 18.4 net wells online and 5.1 net LOS wells, comprised of 3.4 net spuds and 1.7 net permits. The transaction is expected to close in early 2Q 2024 with an effective date of October 1, 2023; therefore, DJ Basin Acquisition 4Q 2023 asset level cash flow is included in Sitio's 4Q 2023 Pro Forma DCF. Sitio plans to fund the DJ Basin Acquisition with cash on hand, cash generated from operations and revolving credit facility borrowings.

FINANCIAL UPDATE

Sitio's fourth quarter 2023 average unhedged realized prices including all expected quality, transportation and demand adjustments were $77.91 per barrel of oil, $1.40 per Mcf of natural gas and $18.72 per barrel of natural gas liquids, for a total equivalent price of $43.65 per barrel of oil equivalent. During the fourth quarter of 2023, the Company received $5.9 million in net cash settlements for commodity derivative contracts and as a result, average hedged realized prices were $80.68 per barrel of oil, $1.66 per Mcf of natural gas and $18.72 per barrel of natural gas liquids, for a total equivalent price of $45.43 per barrel of oil equivalent. This represents a $1.06 per barrel of oil equivalent, or a 2.3% decrease relative to hedged realized prices for the three months ended September 30, 2023.

Consolidated net loss for the fourth quarter of 2023 was $91.7 million, compared to consolidated net income of $0.3 million in the third quarter of 2023. This decrease was driven primarily by a $144.5 million non-cash loss on sale from the divestiture of assets in the Appalachian and Anadarko Basins, and lower revenues from decreased average daily production volumes of 1,124 Boe/d, or 3.0% and a $1.06 per Boe decrease in realized hedged commodity prices, offset partially by a non-cash unrealized gain in derivatives of $12.2 million. For the three months ended December 31, 2023, Adjusted EBITDA was $134.9 million, down 5.3% sequentially from third quarter 2023 Adjusted EBITDA, primarily due to decreased average production volumes of 3.0% and a 2.3% decrease in realized hedged prices per Boe.

As of December 31, 2023, the Company had $877.0 million principal value of total debt outstanding (comprised of $277.0 million of borrowings outstanding under Sitio's revolving credit facility and $600.0 million aggregate principal amount of senior unsecured notes) and liquidity of $588.2 million, including $15.2 million of cash and $573.0 million of remaining availability under its $850.0 million credit facility.

Sitio had approximately $0.4 million of realized gains during 4Q 2023 from its interest rate swap, which had a $202.5 million notional amount during the quarter and expired on December 31, 2023. Sitio did not add to or extinguish any of its commodity swaps or collars during the fourth quarter of 2023. A summary of the Company's existing commodity derivative contracts as of December 31, 2023 is included in the table below.

2023 YEAR END PROVED RESERVES

Estimated 2023 year end proved reserves of 85,293 MBOE attributable to Sitio's interests in its underlying acreage are based on a reserve report prepared by the independent petroleum engineering firm of Cawley, Gillespie & Associates, Inc. in accordance with Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Evaluation Engineers and definitions and guidelines established by the SEC. Of these reserves, approximately 82% were classified as proved developed reserves and 18% were classified as proved undeveloped (“PUD”) reserves. PUD reserves for Sitio included in these estimates relate solely to wells that were spud but not yet producing as of December 31, 2023. The largest driver of year-over-year changes to reserves was extensions of 9,257 MBbls of oil, 26,710 MMcf of natural gas, and 3,723 MBbls of NGLs. Acquisitions increased 2023 year end reserves by 5,803 Mboe; however, the Appalachian and Anadarko Basins Divestiture decreased 2023 year end reserves by 5,340 Mboe, resulting in an overall net increase in 2023 year end reserves from acquisitions and divestitures of 463 Mboe. The following table sets forth information regarding the Company’s net ownership interest in estimated quantities of proved developed and undeveloped oil and natural gas quantities and the changes therein for each of the periods presented.

2024 FULL YEAR FINANCIAL AND OPERATIONAL GUIDANCE

The table below includes Sitio's guidance for full year 2024 and includes impacts from the DJ Basin Acquisition as if the transaction had closed on January 1, 2024. The 36,500 Boe/d midpoint of the pro forma average daily production range is in-line with pro forma average daily production of 36,623 Boe/d for 4Q 2023 and reflects the Company's current expectations for operator activity on its acreage. Full year 2024 Cash G&A guidance is inclusive of a 25%+ increase in headcount since the end of 2022 and technology development and enhancement projects that are expected to further streamline the Company's large-scale minerals acquisitions and management.

(12) Cash tax guidance range is based on expectations at current strip pricing

RETURN OF CAPITAL

The Company's Board of Directors declared a cash dividend of $0.51 per share of Class A Common Stock with respect to the fourth quarter of 2023. The dividend is payable on March 28, 2024 to the stockholders of record at the close of business on March 15, 2024. Based on a 65% payout ratio of fourth quarter 2023 DCF and not including the pro forma impacts from the Oct’23 Effective Date Acquisitions, Sitio's quarterly dividend would have been approximately $0.47 per Class A common share; however, the Company's Board of Directors approved a fourth quarter 2023 dividend of $0.51 per Class A common share, which equates to a 65% payout ratio including pro forma DCF for the full three months ended December 31, 2023.

On February 28, 2024, the Company's Board of Directors also authorized a share repurchase program up to $200 million, and updated its return of capital framework to include share repurchases. The Company has revised its return of capital framework to allow more flexibility to maximize shareholder returns based on market conditions, business outlook, and stock price. The Company plans to continue to allocate a minimum of 65% of DCF to return of capital, comprised of a minimum of 35% of DCF in cash dividends and at least 30% of DCF comprised of additional cash dividends, share repurchases, or a mix of both.

Repurchases may be made from time to time through various methods, including but not limited to open market transactions, privately negotiated transactions, and by other means in accordance with applicable state and federal securities laws, certain of which may be made pursuant to trading plans meeting the requirements of Rule 10b5-1 and 10b-18 under the Securities Exchange Act of 1934, as amended. The timing of repurchases under the repurchase program, as well as the number and value of shares repurchased under the program, will be determined by the Company at its discretion and will depend on a variety of factors, including the market price of the Company's Common Stock, oil and gas commodity prices, general market and economic conditions, available liquidity, compliance with the Company's debt and other agreements, applicable legal requirements and other considerations. The exact number of shares to be repurchased by the Company is not guaranteed, and the program may be modified, suspended, or discontinued at any time without prior notice. The Company is not obligated to purchase any dollar amount or number of shares under the repurchase program.

Non-GAAP financial measures

Adjusted EBITDA, Pro Forma Adjusted EBITDA, Discretionary Cash Flow, Pro Forma Discretionary Cash Flow and Cash G&A are non-GAAP supplemental financial measures used by our management and by external users of our financial statements such as investors, research analysts and others to assess the financial performance of our assets and their ability to sustain dividends over the long term without regard to financing methods, capital structure or historical cost basis. Sitio believes that these non-GAAP financial measures provide useful information to Sitio's management and external users because they allow for a comparison of operating performance on a consistent basis across periods.

We define Adjusted EBITDA as net income (loss) plus (a) interest expense, (b) provisions for income taxes, (c) depreciation, depletion and amortization, (d) non-cash share-based compensation expense, (e) impairment of oil and gas properties, (f) gains or losses on unsettled derivative instruments, (g) change in fair value of warrant liability, (h) management fee to affiliates, (i) loss on extinguishment of debt (j) merger-related transaction costs, (k) write off of financing costs, and (l) loss on sale of oil and gas properties.

We define Pro Forma Adjusted EBITDA as Adjusted EBITDA plus (a) Oct’23 Effective Date Acquisitions EBITDA from October 1, 2023 to December 31, 2023 that is not included in Adjusted EBITDA for the three months ended December 31, 2023 and (b) Brigham Minerals EBITDA October 1 to December 28, 2022.

We define Brigham Minerals EBITDA October 1 to December 28, 2022 as the EBITDA from October 1, 2022 through December 28, 2022 of the assets acquired from Brigham Minerals on December 29, 2022.

We define Discretionary Cash Flow for time periods prior to 2024 as Adjusted EBITDA, less cash and accrued interest expense and cash taxes.

We define Discretionary Cash Flow in 2024 as Adjusted EBITDA, less cash and accrued interest and estimated cash taxes.

We define Pro Forma Discretionary Cash Flow as Discretionary Cash Flow plus (a) Oct’23 Effective Date Acquisitions Discretionary Cash Flow from October 1, 2023 to December 31, 2023 that is not included in Discretionary Cash Flow for the three months ended December 31, 2023 and (b) Brigham Minerals Discretionary Cash Flow October 1 to December 28, 2022.

We define Brigham Minerals Discretionary Cash Flow October 1 to December 28, 2022 as the DCF from October 1, 2022 through December 28, 2022 of the assets acquired from Brigham Minerals on December 29, 2022.

We define Cash G&A as general and administrative expense less (a) non-cash share-based compensation expense, (b) merger-related transaction costs and (c) rental income.

We define Loss on sale of oil and natural gas properties as the non-cash losses incurred from the Appalachian and Anadarko Basins Divestiture in December 2023.

These non-GAAP financial measures do not represent and should not be considered an alternative to, or more meaningful than, their most directly comparable GAAP financial measures or any other measure of financial performance presented in accordance with GAAP as measures of our financial performance. Non-GAAP financial measures have important limitations as analytical tools because they exclude some but not all items that affect the most directly comparable GAAP financial measure. Our computations of Adjusted EBITDA, Pro Forma Adjusted EBITDA, Discretionary Cash Flow, Pro Forma Discretionary Cash Flow and Cash G&A may differ from computations of similarly titled measures of other companies.

The following table presents a reconciliation of Adjusted EBITDA and Pro Forma Adjusted EBITDA to the most directly comparable GAAP financial measure for the periods indicated (in thousands).
