TABLE OF CONTENTS

FORWARD-LOOKING STATEMENTS This prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein contain forward-looking statements that involve risks and uncertainties that could materially affect expected results of operations, liquidity, cash flows and business prospects. Actual outcomes or results may differ from anticipated results, sometimes materially. Forward-looking and other statements regarding our sustainability efforts and aspirations are not an indication that these statements are necessarily material to investors or require disclosure in our filings with the SEC. In addition, historical, current and forward-looking sustainability-related statements may be based on standards for measuring progress that are still developing, internal controls and processes that continue to evolve and definitions, assumptions, data sources and estimates or measurements that are subject to change in the future, including through rulemaking or guidance. Factors that could cause results to differ from those projected or assumed in any forward-looking statement include, but are not limited to:

| • | general economic conditions, including slowdowns and recessions, domestically or internationally; |

| • | our indebtedness and other payment obligations, including the need to generate sufficient cash flows to fund operations; |

| • | our ability to successfully monetize select assets and repay or refinance debt and the impact of changes in our credit ratings or future increases in interest rates; |

| • | assumptions about energy markets; |
