Target greater than mid-teens unlevered returns Prioritize Permian-focused assets to leverage extensive in-basin experience Thoroughly diligence land, geology, and engineering data Understand depth of line-of-sight inventory Avoid single-operator and/or high-NRI concentration risk Strong preference for relationship-driven, privately negotiated acquisitions vs. broad auction processes Sitio’s disciplined underwriting approach results in strong returns (2) Cumulative first 12-month production (boe/d) (1) Data averages first 12 months of underwritten production vs. publicly reported production Acquisition 2 based on cumulative 11 months due to data lag in publicly reported production Actuals based on internal company information and production via publicly reported sources of 6/30/23 Key underwriting criteria Sitio’s recent large acquisitions are all outperforming underwriting assumptions(1) ~12% average outperformance (3)

Consolidation of the minerals sector is still in a very early stage ($ in Bn) ~$69 Bn in 2022 Less than 10 public oil and gas royalty companies vs. 45+ public E&P operators Only a fraction of U.S. oil and gas royalty payments go to current public royalty companies Source:Company filings, FactSet as of 8/18/23, and the EIA as of 5/18/23 (1)Minerals include BSM, DMLP, KRP (pro forma for acquisition announced 8/2/23), PHX, STR, TPL, and VNOM.

Focused on maximizing value and maintaining balance sheet strength Sitio’s financial philosophy and capitalization Generate robust free cash flow Retain up to 35% of Discretionary Cash Flow(1) to protect balance sheet and maintain liquidity Target leverage <1x; expect to hedge cash acquisitions made in a commodity price environment above mid-cycle pricing Maintain underwriting discipline for accretive acquisitions funded with a prudent mix of equity, retained cash flow, and debt Maintain conservative and financially flexible capital structure Note: Senior unsecured notes balance is principal only and not net of any fees Discretionary Cash Flow defined as Adjusted EBITDA less cash interest and cash taxes ü ü ü ü ü Financial philosophy Capitalization 8/7/23 revolving credit facility balance includes a draw to close on a portion of the cash acquisitions

Sitio’s risk management strategy is designed to protect returns on cash acquisitions made in commodity price environments above mid-cycle pricing Hedging methodology Oil and gas hedging summary as of 6/30/23 Utilization of hedging as a risk management strategy to support returns on cash acquisitions that have been underwritten when pricing exceeds mid-cycle pricing Another element of our capital allocation framework designed to balance the return of capital to shareholders while preserving the ability to drive down leverage over time Entered into oil and gas hedging contracts for four cash acquisitions in 2022 No hedges added for recent five acquisitions As of 6/30/23, Sitio had ~$208mm of 3m Term SOFR swaps at 4.652%, which amortizes by $5.6mm per quarter through the contracted term ending 12/29/23

Sitio has no scope 1 and minimal scope 2 emissions Sitio’s differentiated nature of operations results in lower scope 1 and scope 2 emissions than E&P operators(1) E&P operators bear 100% of the environmental liabilities of operations Note: Sitio is making no representation to relative emissions intensity per barrel of oil equivalent associated with its interests compared to E&P operators In accordance with The Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard; Revised Edition, (March 2004) per the World Business Council for Sustainable Development and World Resources Institute Represents Scope 1 and Scope 2 emissions intensity, which is based on gross production for E&P operators.
