Item 7.01    Regulation FD Disclosure.

On October 22, 2026, Biohaven Ltd. (the Company) provided an update on the spinocerebeller ataxia (SCA) program.

The FDA has informed Biohaven that the company’s new drug application resubmission for Vyglxia (troriluzole) in SCA has been accepted for review. The resubmission included new positive supportive analyses.

The FDA communicated that it considers the resubmission a complete response to the November 4, 2025 action letter, and has assigned a user fee goal date in the first quarter of 2027. The FDA plans to convene a meeting of the Peripheral and Central Nervous System Advisory Committee to obtain input from external stakeholders. The anticipated date of the advisory committee meeting will be forthcoming in the near term.

The information in this Item 7.01 is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such a filing.

Cautionary Note Regarding Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including statements regarding the FDA's review of the troriluzole NDA resubmission, the PDUFA target goal date and the potential for approval. The PDUFA target action date is a goal and does not assure that the FDA will act by that date or approve the NDA. The FDA may extend the review period, including if it determines that information submitted during the review constitutes a major amendment, may request additional information, or may issue a complete response letter. Troriluzole is an investigational drug and has not been approved for any indication in the United States.

These statements are subject to risks and uncertainties, including those described in Exhibit 99.1 and under the heading "Risk Factors" in the Company's most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q, that could cause actual results to differ materially. The Company undertakes no obligation to update any forward-looking statement except as required by law.
