Holders may not exercise the warrants if it would result in beneficial ownership exceeding 4.99% or 9.99% of the company’s outstanding common stock, with the possibility to adjust this limit up to 19.99% after providing advance notice.

X4 Pharmaceuticals agreed to indemnify the underwriters against certain liabilities, including those under the Securities Act of 1933, or to contribute to payments the underwriters may be required to make as a result of such liabilities.

In other recent news, X4 Pharmaceuticals announced the pricing of its underwritten public offering, setting the price at $2.90 per share for 45,860,000 shares of common stock. This offering is expected to generate approximately $135 million in gross proceeds, which will be used to fund the development of its rare disease drug program, specifically the pivotal Phase 3 development of mavorixafor in chronic neutropenic disorders. In addition to this financial move, the company has undergone a strategic restructuring, reducing its workforce by 50% to save an estimated $13 million annually. Leadership changes accompany this restructuring, with John Volpone taking on the role of Chief Operating Officer while continuing as President. Furthermore, Stifel has lowered its price target for X4 Pharmaceuticals to $9 from $30, maintaining a Buy rating despite the company’s recent major leadership overhaul. Meanwhile, Altimmune has appointed Dr. Christophe Arbet-Engels as Chief Medical Officer to lead the clinical development of pemvidutide, including a planned Phase 3 trial. Dr. Arbet-Engels replaces Dr. Scott Harris, who will continue with the company as a Senior Strategic Advisor. These developments reflect significant shifts in both companies’ strategies and leadership.
