(5) Net income as reported in the Company’s audited financial statements.

(6) We determined Adjusted EBITDA to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and Non-PEO NEOs in 2024. Adjusted EBITDA is a non-GAAP financial measure. Please see “Segment Financial Information” in our Annual Report on Form 10-K for more information on Adjusted EBITDA, including a reconciliation to Net Loss. Adjusted EBITDA for 2024, 2023, 2022 and 2021 are all continuing operations due to the wind-down of RedfinNow. Adjusted EBITDA for 2020 is consolidated and includes RedfinNow, since we did not distinguish between continuing and discontinuing operations. We may determine a different financial performance measure to be the most important financial performance measure in future years.
