(Nasdaq: BCRX) today announced preliminary, unaudited ORLADEYO (berotralstat) net revenue for the fourth quarter and full year 2025. The company also provided guidance for ORLADEYO net revenue, total revenue, and operating expenses for full year 2026. “2025 was a transformative year for BioCryst. Continued strong demand for ORLADEYO and outstanding patient outcomes have solidified its position as the leading oral, once-daily prophylaxis treatment for HAE. The successful sale of our European ORLADEYO business further strengthened our financial position, and the proposed acquisition of Astria marks an exciting step toward expanding our impact for HAE patients. With our advancing pipeline, flexibility to continue pursuing value-creating business development opportunities, and dedication of our exceptional team, we are confident in our ability to deliver innovative treatments for rare disease patients and drive sustainable growth well into the future,” said Charlie Gayer, President and Chief Executive Officer. Preliminary Fourth Quarter and Full Year 2025 ORLADEYO Revenue, 2026 ORLADEYO and Total Revenue Outlook, and Cash Position at Year-End 2025 Preliminary, unaudited ORLADEYO net revenue in the fourth quarter of 2025 was $151 million (+22 percent y-o-y; +36% y-o-y on a comparable basis, excluding European ORLADEYO revenue for the fourth quarter of 2024). Preliminary, unaudited ORLADEYO net revenue for full year 2025 was $601 million (+37 percent y-o-y), beating the company’s prior guidance range of $590 million to $600 million. Excluding European ORLADEYO revenue for the full year 2025, preliminary, unaudited ORLADEYO net revenue was $563 million (+43 percent y-o-y on a comparable basis). The company expects full year 2026 global net ORLADEYO revenue to be between $625 million and $645 million, and expects full year 2026 total revenue, including RAPIVAB® (peramivir injection), to be between $635 million and $660 million. Preliminary, unaudited cash, cash equivalents, restricted cash & investments as of December 31, 2025, were $338 million. Operating Expense Outlook The company expects full year 2026 non-GAAP operating expenses, excluding stock-based compensation, restructuring, and transaction-related costs, to be between $380 million and $390 million. This does not include operating expenses from Astria Therapeutics after the expected close of the acquisition in Q1 2026. Upon the expected close of the Astria acquisition, the company expects additional non-GAAP operating expenses in 2026 to be between $70 million and $80 million to support the ongoing Phase 3 enrollment of navenibart and commercial readiness manufacturing activities. These costs are expected to trend down over the next two years as the trial is completed and the full impact of operational synergies is realized.

Non-GAAP Financial Measures The information furnished in this release includes non-GAAP financial measures that differ from measures calculated in accordance with generally accepted accounting principles in the United States of America (“GAAP”), including financial measures labeled as “non-GAAP.” We believe providing these non-GAAP measures, which show our results with these items adjusted, is valuable and useful since they allow management and investors to better understand the company’s financial performance in the absence of certain non-cash items such as stock-based compensation and certain special events and allow investors to more accurately understand our current and past period results and more easily compare them to future results. These non-GAAP measures also correspond with the way we expect investors and financial analysts to compare our results. Our non-GAAP measures should be considered only as supplements to, and not as substitutes for or in isolation from, our other measures of financial information prepared in accordance with GAAP, such as GAAP revenue or operating income. Our references to the “non-GAAP” financial measure of preliminary, unaudited 2025 ORLADEYO revenue, excluding European ORLADEYO revenue for the full year 2025, constitutes a non-GAAP financial measure. It refers to our preliminary GAAP results, adjusted to show the results without including $38 million of European ORLADEYO revenue for the nine months ended September 30, 2025. Our measure of 36% y-o-y growth on a comparable basis for preliminary, unaudited ORLADEYO net revenue in the fourth quarter of 2025 was calculated using the non-GAAP financial measure of Q4 2024 ORLADEYO net revenue, adjusted to exclude $13 million of European ORLADEYO revenue for the three months ended December 31, 2024. Our measure of 43% y-o-y growth on a comparable basis for preliminary, unaudited ORLADEYO net revenue for the full year 2025 was calculated using the non-GAAP financial measure of full year 2024 ORLADEYO net revenue, adjusted to exclude $43 million of European ORLADEYO revenue for the twelve months ended December 31, 2024. Our reference to expected non-GAAP profitability excludes stock-based compensation, restructuring and transaction-related costs. We also provide our non-GAAP operating expense outlook for full year 2026, which refers to our expected GAAP operating expense, excluding stock-based compensation, restructuring and transaction-related costs. We have not provided a reconciliation against the comparable forward-looking GAAP measure because we are unable to predict with reasonable certainty the full amount of stock-based compensation expense or restructuring and transaction-related costs for the full year 2026 without unreasonable effort. Stock-based compensation expense is uncertain and depends on various factors, including our future hiring and retention needs, as well as the future fair market value of our common stock, which is difficult to predict and subject to change. In addition, we are unable to predict with reasonable certainty the full amount of restructuring and transaction-related costs as the closing of the proposed Astria acquisition is still pending and the related costs are dependent on various factors that have not yet occurred. The actual amount of stock-based compensation, restructuring and transaction-related costs for the full year 2026 could have a material impact on GAAP reported results for the guidance period.

Please refer to the documents BioCryst files periodically with the Securities and Exchange Commission (the “SEC”), specifically BioCryst’s most recent Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K, which identify important factors that could cause actual results to differ materially from those contained in BioCryst’s projections and forward-looking statements.
