Item 1.01			Entry Into a Material Definitive Agreement.

On May 8, 2024, X4 Pharmaceuticals, Inc.

The Company received the PRV under a United States Food and Drug Administration (“FDA”) program intended to encourage the development of treatments for rare pediatric diseases. The Company was awarded the PRV in April 2024 when the FDA approved XOLREMDITM (mavorixafor) which is indicated in patients 12 years of age and older with WHIM syndrome (warts, hypogammaglobulinemia, infections and myelokathexis) to increase the number of circulating mature neutrophils and lymphocytes.

The transactions contemplated by the Asset Purchase Agreement contains customary representations, warranties and covenants.

The foregoing description of the Asset Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the text of the Asset Purchase Agreement, which will be filed as an exhibit to the Company’s Quarterly Report on Form 10-Q for the fiscal quarter ending June 30, 2024.

Exhibit 99.1

X4 Pharmaceuticals Announces $125 Million Capital Infusion from $105

Million Sale of Priority Review Voucher and $20 Million Drawdown from

Existing Loan Facility

$125 million of non-dilutive capital extends projected cash runway into late 2025, excluding expected commercial sales from XOLREMDI™ (mavorixafor)

XOLREMDI, the first drug indicated in patients with WHIM syndrome, received U.S. FDA approval in April 2024

BOSTON, May 9, 2024 – X4 Pharmaceuticals (Nasdaq: XFOR), a company driven to improve the lives of people with rare diseases of the immune system, today announced that it has completed the sale of its Rare Pediatric Disease Priority Review Voucher (PRV) to an undisclosed purchaser for $105 million and that it has drawn an additional tranche of $20 million under its existing loan facility with Hercules Capital, Inc. (NYSE: HTGC). Both transactions result from the U.S. Food and Drug Administration (FDA) approval of the company’s first product, XOLREMDI™ (mavorixafor), in late April.

“This infusion of non-dilutive capital provided by these transactions extends our projected cash runway into late 2025, excluding expected commercial product sales, and provides us with additional financial strength and flexibility as we execute on the XOLREMDI launch in WHIM syndrome and continue to advance mavorixafor into a potential second indication, with the planned initiation of a Phase 3 trial this quarter in certain chronic neutropenic disorders,” said Adam Mostafa, Chief Financial Officer of X4 Pharmaceuticals.

Under the Rare Pediatric Disease program, the FDA awards PRVs to sponsors of rare pediatric disease product applications that meet certain criteria to encourage development of new drugs and biologics for the prevention and treatment of rare pediatric diseases. The term loan facility with Hercules Capital provides for up to $115 million of term loans in the aggregate, available to be funded in multiple tranches, and is in an interest-only period until July 2027. The $105 million of gross funds received from the sale of the PRV and the $20 million drawn from the existing loan facility add to the $82 million in cash, cash equivalents, restricted cash, and short-term marketable securities reported as of March 31, 2024.

About WHIM Syndrome and XOLREMDI™ (mavorixafor)

WHIM (warts, hypogammaglobulinemia, infections and myelokathexis) syndrome is a rare, combined primary immunodeficiency and chronic neutropenic disorder; people with WHIM syndrome characteristically have low blood levels of neutrophils (neutropenia) and lymphocytes (lymphopenia), and as a result, experience serious and/or frequent infections. XOLREMDI (mavorixafor) is a selective CXCR4 receptor antagonist approved in the U.S. for use in patients 12 years of age and older with WHIM syndrome to increase the number of circulating mature neutrophils and lymphocytes.

About X4 Pharmaceuticals

X4 is delivering progress for patients by developing and commercializing innovative therapies for those with rare diseases of the immune system and significant unmet needs. Leveraging our expertise in CXCR4 and immune system biology, we have successfully developed mavorixafor, which has received U.S. approval as XOLREMDI™ (mavorixafor) capsules in its first indication. We are also evaluating the use of mavorixafor in additional potential indications. X4 corporate headquarters are in Boston, Massachusetts and our research center of excellence is in Vienna, Austria.
