Chris Conoscenti, Chief Executive Officer of Sitio, commented, “In the third quarter, our assets delivered another steady performance that reflected operator trends in Permian and broader US drilling and completion activity. We continue to pursue multiple consolidation opportunities and are optimistic about improving competitive dynamics heading into 2024. During the third quarter, we completed the four previously announced cash acquisitions of high-quality Permian minerals and royalties totaling approximately $181 million and on November 3, 2023, we agreed to sell our lower-margin Appalachia and Anadarko assets for $117.5 million. Our inaugural senior unsecured notes offering that closed on October 3, 2023, allowed us to refinance our existing unsecured notes and achieve more than $11 million in expected annual interest expense savings. Our team continued to innovate by building new customized automation tools to improve the efficiency with which we manage such a large amount of new data each month. This streamlines processing and tracking royalty payments, monitoring ongoing operator activity on our acreage and positions Sitio to smoothly integrate additional data from future acquisitions. I'm proud of our team for executing well on such a broad range of strategic, financing and operational initiatives throughout the quarter.”

FINANCIAL UPDATE

Sitio's third quarter 2023 average unhedged realized prices including all expected quality, transportation and demand adjustments were $80.21 per barrel of oil, $1.54 per Mcf of natural gas and $18.14 per barrel of natural gas liquids, for a total equivalent price of $45.00 per barrel of oil equivalent. During the third quarter of 2023, the Company received $5.1 million in net cash settlements for commodity derivative contracts and as a result, average hedged realized prices were $82.21 per barrel of oil, $1.84 per Mcf of natural gas and $18.14 per barrel of natural gas liquids, for a total equivalent price of $46.49 per barrel of oil equivalent. This represents a $2.04 per barrel of oil equivalent, or a 5% increase relative to hedged realized prices for the three months ended June 30, 2023.

Consolidated net income for the third quarter of 2023 was $0.3 million, which is $3.2 million more than consolidated net income in the second quarter of 2023. This increase was driven primarily by increased commodity prices and offset by net commodity derivatives losses of $24.1 million, which was comprised of a $29.2 million non-cash unrealized loss and a $5.1 million realized gain. For the three months ended September 30, 2023, Adjusted EBITDA was $142.4 million, up 12% sequentially from second quarter 2023 Adjusted EBITDA, primarily due to increased production volumes and commodity prices.

As of September 30, 2023, the Company had $1,006.0 million principal value of total debt outstanding (comprised of $601.0 million drawn on Sitio's revolving credit facility and $405.0 million of senior unsecured notes) and liquidity of $250.3 million, including $1.3 million of cash and $249.0 million of remaining availability under its $850.0 million credit facility. In September 2023, Sitio made its fourth consecutive quarterly amortization payment of $11.3 million at par value on its senior unsecured notes, reducing the principal from $416.3 million to $405.0 million as of the end of the third quarter 2023.

2H 2023 FINANCIAL AND OPERATIONAL GUIDANCE

Sitio is revising its guidance for Cash G&A for the full year 2023 to a range of $27.0 million to $28.0 million based on results to date and expectations for 4Q 2023, which includes incremental G&A for expected new employees. The midpoint of Sitio's new Cash G&A guidance range for full year 2023 is $27.5 million, an approximate 6% increase from the midpoint of prior guidance. There are no other changes to prior 2H 2023 guidance, but for convenience all guidance metrics are shown in the table below.

SENIOR UNSECURED NOTES REFINANCING

On October 3, 2023, the Company issued and sold $600.0 million aggregate principal amount of its 2028 Senior Notes. The net proceeds of the Notes Offering were used to (i) fund the redemption of all of the outstanding aggregate principal amount of the 2026 Senior Notes, which occurred concurrently with the consummation of the Notes Offering and (ii) repay a portion of the outstanding borrowings under the Company's revolving credit facility. As of November 3, 2023, the Company had $981.0 million principal value of total debt outstanding (comprised of $381.0 million drawn on Sitio's revolving credit facility and $600.0 million of senior unsecured notes due 2028) and liquidity of $470.9 million, including $1.9 million of cash and $469.0 million of remaining availability under its $850.0 million credit facility.

DIVESTITURE OF APPALACHIA AND ANADARKO ASSETS

On November 3, 2023, the Company entered into a definitive purchase and sale agreement to sell all of its mineral and royalty interests in the Appalachia and Anadarko Basins to an undisclosed third party for $117.5 million of cash consideration, subject to customary closing adjustments. In aggregate for the three months ended September 30, 2023, production associated with these assets was 2,095 Boe/d (14% oil) and revenues were $3.8 million from oil, natural gas and natural gas liquids. As of September 30, 2023, there were approximately 0.7 net LOS wells underlying these assets, comprised of approximately 0.5 net spuds and 0.3 net permits. Sitio plans to use the net proceeds to repay borrowings on its revolving credit facility and build additional liquidity to pursue acquisitions of assets that are more comparable to the growth and returns profile of Sitio’s recent Permian Basin acquisitions. The transaction has an effective date of September 1, 2023 and is expected to close in the fourth quarter of 2023.

Sitio did not add to or extinguish any of its commodity swaps or collars during the third quarter of 2023. A summary of the Company's existing commodity derivative contracts as of September 30, 2023 is included in the table below.

THIRD QUARTER 2023 CASH DIVIDEND

The Company's Board of Directors declared a cash dividend of $0.49 per share of Class A Common Stock with respect to the third quarter of 2023. The dividend is payable on November 30, 2023 to the stockholders of record at the close of business on November 21, 2023. Based on a 65% payout ratio of third quarter 2023 Discretionary Cash Flow and not including the pro forma impacts from the Cash Acquisitions, Sitio's quarterly dividend would have been approximately $0.48 per Class A common share; however, the Company's Board of Directors approved a third quarter 2023 dividend of $0.49 per Class A common share, which equates to a 65% payout ratio including pro forma Discretionary Cash Flow for the full three months ended September 30, 2023 for the Cash Acquisitions that closed during the third quarter 2023.

FINANCIAL RESULTS

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

We define Pro Forma Adjusted EBITDA as Adjusted EBITDA plus Cash Acquisitions EBITDA from July 1, 2023 to September 30, 2023 that is not included in Adjusted EBITDA for the three months ended September 30, 2023.

We define Discretionary Cash Flow as Adjusted EBITDA, less cash interest expense and cash taxes.

We define Pro Forma Discretionary Cash Flow as Discretionary Cash Flow plus Cash Acquisitions Discretionary Cash Flow from July 1, 2023 to September 30, 2023 that is not included in Discretionary Cash Flow for the three months ended September 30, 2023.

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.

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 period indicated (in thousands).

The following table presents a reconciliation of Discretionary Cash Flow and Pro Forma Discretionary Cash Flow to the most directly comparable GAAP financial measure for the period indicated (in thousands).
