Shares of Novavax Inc. (NVAX) plunged over 9% in pre-market trading on Thursday after the biotechnology company clarified that it has not reaffirmed or updated its full-year 2024 financial guidance for the U.S. COVID-19 vaccine market, contrary to a recent analyst report.
On Wednesday, Novavax's stock soared nearly 19% after Jefferies analyst Roger Song suggested in a research note that the company would likely meet its 2024 revenue guidance. Song's assessment was based on a meeting with Novavax management, where he concluded that trends in this year's COVID-19 vaccine sales would follow a similar pattern as 2023.
However, Novavax swiftly clarified that while it is aware of the analyst report, it has not provided any updates or reaffirmations regarding its full-year 2024 outlook since the Q2 2024 financial results in August. This clarification appeared to trigger a sharp reversal in investor sentiment, resulting in a significant pre-market decline in the company's share price.
