(“Cantor”) and JonesTrading Institutional Services LLC (“Jones”), as agents (the “Sales Agreement”).

As previously disclosed, on July 1, 2025, the Company notified Cantor and Jones that it was terminating a prior prospectus filed with the SEC on February 8, 2024 and dated April 12, 2024 related to the offer and sale of shares of the Company’s common stock having an aggregate offering price of up to $100.0 million pursuant to the Sales Agreement.
