About This Proxy Statement

Policies and Procedures

This proxy statement includes statements regarding various policies, standards, approaches, methodologies, procedures, processes, strategies, programs, initiatives, assessments, technologies, practices, metrics, and similar measures related to our sustainability and climate-related data, disclosures, targets, actions, performance, and compliance systems (collectively, “Policies and Procedures”). References to Policies and Procedures in this proxy statement do not represent guarantees or promises about their efficacy or continued implementation or use, or any assurance that any such Policies and Procedures will apply in every case. While we believe that our Policies and Procedures reflect our business strategy and are reasonable at the time made or used, as our business or applicable methodologies, standards, or regulations develop and evolve, we may revise or cease reporting or using certain Policies and Procedures if we determine that they are no longer appropriate, or we are otherwise required to do so. Such Policies and Procedures are subject to risks, uncertainties, and other factors, some of which are beyond our control and are difficult to predict, and there may be circumstances, factors, or considerations that may cause different implementation thereof, revised or discontinued use thereof, or exceptions in specific instances.

Cautionary Statement Concerning Forward-Looking Statements

This proxy statement contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), including, but not limited to, statements about Policies and Procedures. You can identify forward-looking statements by words such as “should,” “strive,” “pursue,” “potential,” “committed,” “advancing,” “developing,” “evaluating,” “intend,” “anticipate,” “forecast,” “on track,” “would,” “continue,” “aimed,” “considering,” “poised,” “focused,” “opportunity,” “scheduled,” “believe,” “estimate,” “expect,” “seek,” “could,” “may,” “target,” “goal,” “aspiration,” “plan,” and other similar expressions that convey the uncertainty of future events or outcomes. Forward-looking statements in this proxy statement also include those related to our publicly disclosed target regarding greenhouse gas (“GHG”) emissions reductions/displacements, expectations related to our low-carbon fuels strategy and businesses, outcomes from compensation incentives, and our board of directors composition, leadership, and oversight structure, expected timing of completion, cost, and performance of projects and strategic actions, future market, regulatory, and industry conditions, future capital allocation decisions, future operating and financial performance, expected timing or issuance of future disclosures, future production and manufacturing ability and size, and management of risks and uncertainties, among other matters. It is important to note that actual results could differ materially from those expressed, suggested, or forecasted in any forward-looking statements based on numerous factors, including those outside of our control, such as legislative or political changes or developments, market dynamics, cyberattacks, weather events, and other matters affecting our operations, financial performance, or the demand for our products. These factors also include, but are not limited to, the uncertainties that remain with respect to current or contemplated legal, political, or regulatory developments that are adverse to or restrict refining and marketing operations, that impose taxes or penalties on profits, windfalls, or margins, or require certain disclosures, global geopolitical and other conflicts and tensions, the impact of inflation on margins and costs, economic activity levels, tariffs, duties, sanctions, and other trade restrictions, and the adverse effects the foregoing may have on our business plan, strategy, operations, and financial performance. When considering these forward-looking statements, you should also consider the risk factors and other cautionary statements contained in our annual report on Form 10-K, quarterly reports on Form 10-Q, and other reports filed with the United States (“U.S.”) Securities and Exchange Commission (the “SEC”) and available on our website noted under “Available Information” below (under Investors > Financials > SEC filings). These risks could cause actual performance, results, and Policies and Procedures to differ materially from those expressed, suggested, or forecasted in any forward-looking statement. Such forward-looking statements speak only as of the date they are made and we do not intend to update these statements unless we are required by applicable securities laws to do so.
