Copyright © 2021, Oracle and/or its affiliates CEO Compensation at a Glance

Copyright © 2021, Oracle and/or its affiliates Fiscal 2021 Performance-Based Compensation for Larry Ellison & Safra Catz Pay Element Fiscal 2021 Outcome Annual Cash Bonus Mr. Ellison and Ms. Catz each earned an annual cash bonus of $9,584,656 (192% of target) based on the bonus plan formula approved by the Compensation Committee The financial performance metric for determining the amount of the bonus changed from year-over-year growth in our non-GAAP pre-tax profits, which was the metric used in recent years, to non-GAAP operating income growth PSOs The $80 stock price goal was satisfied and one tranche (1/7th) of the PSOs vested on June 30, 2021 Although the first market capitalization goal of the PSOs was satisfied in fiscal 2021, a corresponding operational performance goal has not yet been satisfied and none of the other six tranches have vested

Copyright © 2021, Oracle and/or its affiliates Extension of PSO Performance Period The Compensation Committee extended the PSO performance period by three fiscal years from May 31, 2022 to May 31, 2025 The Compensation Committee responded to stockholder feedback by extending the PSO performance period while maintaining the other existing terms applicable to the PSOs. The Compensation Committee believes that the goals associated with the PSOs are tailored to focus our executives on Oracle’s most important long-term strategy. The PSO goals remain very challenging. The matching of operational performance goals with market capitalization goals ensures that stockholders will benefit from the achievement of the goals in the future.
