On May 6, 2026, the Board of Directors (the “Board”) of Oracle Corporation (“Oracle”) unanimously elected Tomislav Mihaljevic to serve as a director, effective immediately. Dr. Mihaljevic has not been named and is not currently expected to be named, to any committee of the Board at this time.

Dr. Mihaljevic will be granted restricted stock units for shares of Oracle common stock (the “RSUs”) on May 31, 2026 in accordance with Oracle’s Amended and Restated 1993 Directors’ Stock Plan and in a manner consistent with Oracle’s annual award for non-employee directors generally. The RSUs will fully vest on the first anniversary of the date of grant provided Dr. Mihaljevic continues to serve as a director on the vest date. Dr. Mihaljevic will also receive the standard cash compensation for Oracle’s non-employee directors. There are no arrangements or understandings between Dr. Mihaljevic and any other persons pursuant to which he was elected to the Board. Dr. Mihaljevic has no related party transactions with Oracle that are reportable under Item 404(a) of Regulation S-K and has no family relationships with any director, executive officer or nominee for director or executive officer of Oracle.

Dr. Mihaljevic entered into Oracle’s standard form of indemnification agreement pursuant to which Oracle will indemnify him for certain actions taken in his capacity as a director.
