Explanatory Note

This Current Report on Form 8-K/A (the "Form 8-K/A") amends the Current Report on Form 8-K filed by BioCryst Pharmaceuticals, Inc. (the "Company") with the Securities and Exchange Commission (the "SEC") on June 29, 2026 (the "Original Report") and is being filed solely to amend and supplement the Company's disclosure contained in Item 2.05 of the Original Report. The Original Report otherwise remains unchanged.

Item 2.05. Costs Associated with Exit or Disposal Activities.

On June 29, 2026, the Company announced its plan to discontinue the Company's internal discovery programs and close its Discovery Center of Excellence facility in Birmingham, Alabama (the "Plan") as part of the Company's ongoing strategic evolution to strengthen its rare disease pipeline. At the time of the Original Report, the Company was not able to make a good faith estimate of the costs it would incur in connection with the Plan.

The Company now estimates that it will incur between $6.2 and $7.5 million in one-time expenses in connection with employee termination benefits and severance, of which approximately $5.3 to $6.6 million are expected to be cash expenditures. While the Company expects costs associated with the Plan to also include costs related to the closure of the Discovery Center of Excellence facility, such as contract and lease termination or asset impairment charges, among other costs, management's analysis of the Plan's execution is still ongoing. As such, the Company is currently unable in good faith to estimate the total amount or range of amounts expected to be incurred in connection with such facility closure-related costs, or of any charges that will result in future cash expenditures. The Company will file an amended Current Report on Form 8-K or other periodic report after it makes a determination of such an estimate or range of estimates.

These statements reflect our current views with respect to future events and are based on assumptions and are subject to risks and uncertainties. Given these uncertainties, you should not place undue reliance on these forward-looking statements.
