 3  Meeting Information  Proposal  Board recommendation  1. Election of directors  FOR(each director nominee)  2. Advisory vote to approve named executive officer compensation  FOR  3. Ratification of selection of KPMG as Occidental’s independent auditor  FOR  4. Shareholder proposal requesting Occidental set and disclose quantitative short-, medium- and long-term greenhouse gas (GHG) emissions reduction targets consistent with the Paris Agreement  AGAINST  Items of Business  As always, we value your views and encourage you to share your opinions with us. This past year, Occidental proactively engaged with shareholders collectively representing a majority of shares outstanding, with independent director participation in many of these discussions. Going forward, Occidental remains committed to regular and transparent engagement with shareholders and other stakeholders, and shareholder feedback will continue to inform our viewpoints and decisions.  DATE AND TIME  Friday, May 6, 2022 at 9:00 a.m. Central Time  LOCATION  Live webcast: www.virtualshareholdermeeting.com/OXY2022  RECORD DATE  Each shareholder of record as of the close of business on March 11, 2022 (the record date) is entitled to receive notice of, attend and vote at the meeting. 

 Oxy recognizes the value of shareholder engagement and has actively engaged with Follow This, including:  The Board recommends that shareholders vote AGAINST this proposal because:   Oxy has already set quantitative short-, medium- and long-term goals for Scope 1, 2 and 3 emissions that align with the goals of the Paris Agreement.  Oxy’s targets are the result of a disciplined and rigorous target setting process, overseen by our Board.  This process integrated input from shareholders and other stakeholders, incorporated insights from scenario modeling and assessments, and capitalized on Oxy’s competitive strengths.  Oxy is committed to public reporting that provides updates on progress toward our goals.  Annual Meeting Shareholder Engagement  4  Climate Strategy  Our Concerns with the Shareholder Proposal  Engagement with the Proponent  2021 discussions that led to the settled withdrawal of Follow This’ shareholder proposal  Engagement with Follow This during our recent fall/winter off-season engagement  Several discussions in connection with this 2022 proposal   Follow This has questioned whether our existing emissions reduction targets are Paris-aligned.   As demonstrated on the following slides, we strongly believe that our targets are Paris-aligned and inextricably linked with our long-term strategy for a net-zero future. 

 Pathway to Net Zero  Annual Meeting Shareholder Engagement  5  Climate Strategy  Oxy has set the following Scope 1, 2 and 3 goals, among others, to achieve net zero across our total emissions inventory in accordance with the Paris Agreement1:  2024  Reduce total operational GHG emissions2 from Oil & Gas and OxyChem by  3.68 million metric tons per annum (MTPA)  CO2e*†  2032  Facilitate geologic storage or use of 25 MTPA CO2e of captured CO2*  2040  Achieve net-zero emissions in our operations and energy use (Scope 1 and 2) before 2040 with the ambition to achieve before 2035  2050  Achieve net zero for our total emissions inventory including product use  with an ambition to  achieve before 2050  BEYOND  Capture and remove global emissions beyond our Scope 1, 2 and 3  1PointFive and future OLCV technology development help accelerate Oxy’s emission reduction to net zero  1 See Appendix for a comprehensive set of Oxy’s goals  2 Compared to 2021 emissions  3 How ambitious are oil and gas companies’ climate goals? (2021, October 22). Science, 374 (6566). https://www.science.org/doi/10.1126/science.abh0687  Developing and deploying CCUS and DAC technology are key to Oxy’s pathway to net zero  * Short- and medium-term goals announced in December 2021.  † “CO2e” means carbon dioxide (CO2) equivalent — obtained by converting a mixture of GHG to a single number based on the global warming potential currently applied in the U.S. EPA GHG Reporting Program for each individual GHG in the mixture.   These goals are inextricably linked to the strategy adopted by our executive team and our Board of Directors. In turn, this strategy has been designed to capitalize on Oxy’s competitive strengths.  TAKE-AWAY: Oxy is working to lead the industry toward a lower-carbon energy future.  Oxy is one of the 3 oil & gas companies whose long-term targets were viewed by TPI as aligned with the 1.5°C pathway. Also recognized in Science as the only oil & gas company that plans to reduce its GHG intensity below the 1.5°C benchmark by 2050.3

 Aligning our Scope 3 Goals with A Net-Zero Trajectory  Annual Meeting Shareholder Engagement  10  Climate Strategy  Scenarios that involve new technologies are inherently challenging to forecast and non-linear. To set medium-term carbon management targets that are consistent with a net-zero-by-2050 trajectory, we leverage CCUS and DAC projection pathways – and carbon capture growth factor assumptions – from a range of external sources.  IEA1 NeT-Zero by 2050 RoadMAP   Source: “Net-Zero America” by Princeton University is licensed under CC BY NC 4.0.  Source: IEA (2021) Net Zero by 2050: A Roadmap for the Global Energy Sector.

 ONE SIZE DOES NOT FIT ALL  Annual Meeting Shareholder Engagement  12  Climate Strategy  However, applying this statement uniformly to all companies and their pathways does not take into account, among other things:  the range of 200+ scenarios in the IPCC 1.5°C Report  the different rates of emissions reductions in different sectors in these scenarios  the importance of CCUS and DAC to reaching net-zero by 2050 as recognized by the IPCC and the IEA  the assumed trajectory of CCUS and DAC development in net-zero-by-2050 scenarios     In our discussions with Follow This and in related media coverage, Follow This has asserted that alignment with the Paris Agreement requires reducing Scope 1, 2 and 3 emissions by roughly half by 2030.   This assertion appears to be based on a statement in the IPCC 1.5°C Report that in certain 1.5°C model pathways, global net anthropogenic CO2 emissions decline by about 45% by 2030.1  1 Rogelj, J., D. Shindell, K. Jiang, S. Fifita, P. Forster, V. Ginzburg, C. Handa, H. Kheshgi, S. Kobayashi, E. Kriegler, L. Mundaca, R.

An IPCC Special Report on the impacts of global warming of 1.5°C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty [Masson-Delmotte, V., P.

Tignor, and T. Waterfield (eds.)]. In Press.  BOTTOM LINE:   Oxy has established proactive, Paris-aligned short-, medium- and long-term targets that tie directly to our ambitious strategy to achieve net zero for Oxy’s Scope 1, 2 and 3 emissions by 2050. Our targets and strategy recognize that all avenues of emissions mitigation, including renewables, energy efficiency, methane capture, carbon removal and CCUS, will be needed to reach net zero. While Oxy’s net-zero strategy is multi-faceted, CCUS and DAC are at the heart of our strategy, which capitalizes on Oxy’s competitive strengths.   Follow This’ view of Paris alignment is counter to Oxy’s STRATEGY, COMPETITIVE STRENGTHS AND value proposition.   Paris-aligned 1.5°C scenarios require a portfolio of climate solutions and include a variety of pathways with varying trajectories for different technologies and industries—no one trajectory can apply to all industries.
