Mineral and Royalty Highlights 5
Mineral and royalty businesses are a structurally advantaged asset class • Mineral interests are perpetual real property interests and when leased for royalties, have no development capital expenses • No physical operations or associated regulatory risks SIMPLICITY • No environmental liabilities; zero scope 1 emissions and scope 2 emissions are only from power consumption at Sitio office locations • Highest margin component of the energy value chain, with limited direct exposure to cost inflation, enables sector leading EBITDA to free cash flow conversion ratios PROFITABILITY • Ability to return a majority of discretionary cash flow to shareholders while maintaining a conservative balance sheet • No field staff or lease operating expenses and 100% of capital expenditures are discretionary and tied to corporate investments and acquisitions EFFICIENCY • Data management systems improve royalty management capabilities • Highly fragmented mineral and royalty ownership with limited number of buyers capable of large-scale acquisitions SCALABILITY • G&A expenses do not increase linearly with company scale 6

(1) Emissions estimated 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. Scope 1 and Scope 2 emissions estimated include power consumption at Sitio office locations but not production in accordance with protocol. Does not give pro forma effect to emissions associated with Austin office lease assumed in December 2022 (2) Data from Greenhouse Gas Equivalencies Calculator on www.epa.gov 32 (3) Represents Scope 1 and Scope 2 emissions intensity, which is based on gross production for E&P operators. E&P operators include AR, CHK, CIVI, CPE, CPG, CRGY, CTRA, DECPF, DVN, EOG, ERF, FANG, GPOR, HES, MRO, MUR, OVV, PR, SM, SWN and VTLE. Sitio metrics represent MT CO e per net MBOE of reported net production for Desert Peak Minerals and Falcon Minerals for 2021. Sitio metrics exclude electricity usage and production from assets acquired from Brigham Minerals. 2
Sitio investment thesis Mineral and royalty interest ownership provides unique, cost advantaged oil and gas exposure and the highest free cash flow margins in the oil & gas value chain Well-positioned as a natural aggregator in a highly fragmented space, with a proven strategy for meaningful, returns-focused consolidation Premier asset base focused at the front end of operators’ cost curves, supported by a core Permian Basin footprint and exposure to major U.S. oil & gas plays Disciplined capital allocation focused on value creation and returns with target long-term leverage <1.0x and prudent hedging strategy for cash acquisitions Best-in-class governance model led by experienced Board and management 33
