On May 19, 2026, Corcept Therapeutics Incorporated (the "Company") learned that the United States Department of Justice (the "DOJ") had filed a Notice of Election to Decline Intervention (the "Notice") in a civil qui tam action filed against the company, captioned *U.S. et al. ex rel. Stephen Elliott v. Corcept Therapeutics, Inc.*, No. 17-CV-1303 (SRC) (D.N.J.). That action was initiated in February 2017, in the District Court of New Jersey, by a former employee of the Company (the "Relator"). In connection with that action, the DOJ previously issued a records subpoena to the Company in November 2021, seeking information relating to the sale and promotion of Korlym<sup>®</sup>, the Company's relationships with and payments to health care professionals who prescribe or recommend Korlym, and prior authorizations and reimbursement for Korlym, to which the Company responded in full. The DOJ's Notice indicates that the DOJ, the California Department of Insurance, and the named Plaintiff States have all declined to intervene in the Relator's lawsuit. On June 2, 2026, the Relator served the Company with an amended complaint. The Company intends to vigorously defend against all of the Relator's claims.

#### Forward-Looking Statements
This Current Report on Form 8-K contains forward-looking statements that involve risks and uncertainties, such as statements related to the Company's intent to vigorously defend against all of the Relator's claims. The risks and uncertainties involved include risks detailed from time to time in the Company's periodic reports and other filings with the Securities and Exchange Commission, including the Company's most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q. You are cautioned not to place undue reliance on forward-looking statements, which are based on the Company's current expectations and assumptions and speak only as of the date of this Current Report on Form 8-K. The Company assumes no obligation to publicly revise or update any forward-looking statement in this Current Report on Form 8-K to reflect changes in information, events or circumstances after the date of this Current Report on Form 8-K, except as required by law.
