Risks Related to the Facility

It is not possible to predict the actual number of shares of our Common Stock, if any, we will sell under the Purchase Agreement to Chardan, or the actual gross proceeds resulting from those sales or the dilution to you from those sales.

On September 29, 2025, we entered into the Purchase Agreement with Chardan, pursuant to which we may sell to Chardan up to $500.0 million of shares of our Common Stock (the “Total Commitment”), upon the terms and subject to the conditions and limitations set forth in the Purchase Agreement. The shares of our Common Stock that may be issued under the Purchase Agreement may be sold by us to Chardan at our discretion from time to time until the earliest to occur of (i) the 36-month anniversary of the effective date of the registration statement of which this prospectus forms a part, (ii) the date on which Chardan has purchased the Total Commitment pursuant to the Purchase Agreement, (iii) the date on which our Common Stock fails to be listed or quoted on Nasdaq or any successor Principal Market (as defined in the Purchase Agreement), and (iv) the date on which, pursuant to or within the meaning of any bankruptcy law, we commence a voluntary case or any person commences a proceeding against us, a custodian is appointed for us or for all or substantially all of our property, or we make a general assignment for the benefit of our creditors (each date of such termination, an “Automatic Termination Event”).

We generally have the right to control the timing and amount of any sales of our Common Stock to Chardan under the Purchase Agreement. Sales
