Positives

• XOLREMDI generated $2.6 million in net revenue since its launch in May 2024.
• The company secured a $28.5 million upfront payment through a partnership with Norgine Pharma UK.

• The company is undergoing a strategic restructuring, including reducing overall headcount and discontinuing research efforts.
• The company closed its facility in Vienna, Austria.

Risks

• X4's restructuring activities may be more costly or time-consuming than expected or may not achieve their intended results and savings.
• The expected decrease in annual spending could negatively impact X4's commercial plans and strategy for mavorixafor.
• The expected sufficiency of X4's existing cash resources and runway may not be accurate resulting in the need for additional financing sooner than anticipated or unexpected liquidity constraints.
• The design and rate of enrollment for clinical trials, including the current design of the ongoing Phase 3 clinical trial evaluating mavorixafor in certain chronic neutropenic disorders may not enable successful completion of the trial(s).
• The commercial opportunity for mavorixafor in chronic neutropenic disorders may be smaller than anticipated.

Future Outlook

X4 expects a ramp-up in XOLREMDI sales in 2025 and anticipates full enrollment in the Phase 3 4WARD trial in the third or fourth quarter of 2025, with top-line data expected in the second half of 2026; the company believes it has sufficient funds to support operations into the first half of 2026.

Management Comments

• As expected, 2024 was a transformative year for the company and our momentum has continued into 2025, said Paula Ragan, Ph.D., President and Chief Executive Officer of X4 Pharmaceuticals.
• Market research and patient testimonials continue to strengthen our belief that there remains significant untapped potential for XOLREMDI for the U.S. and possibly global WHIM patient populations.
• We are equally confident in mavorixafors future potential to address unmet needs in the global CN community.

Industry Context

X4 Pharmaceuticals is focused on developing and commercializing therapies for rare diseases of the immune system, specifically targeting CXCR4 and immune system biology; the company's progress with XOLREMDI and mavorixafor positions it within the competitive landscape of rare disease therapeutics.

Comparison to Industry Standards

• The $2.6 million in net revenue for XOLREMDI since launch is relatively low compared to other rare disease drug launches, suggesting a slower initial uptake.
• The upfront payment of $28.5 million from Norgine is within the typical range for licensing agreements in the pharmaceutical industry, but the total potential value of $254.5 million depends on regulatory and commercial milestones.
• The expected $30-35 million in annual spending reduction through restructuring is a significant cost-cutting measure, potentially improving the company's financial position.

Stakeholder Impact

• Shareholders: The financial results and strategic restructuring may impact shareholder value.
• Employees: The headcount reduction will affect employees.
• Patients: Continued development of mavorixafor offers potential benefits for patients with rare immunodeficiencies.
• Partners: The partnerships with Norgine and taiba rare will impact commercialization efforts.

Next Steps

• Continue commercialization of XOLREMDI in the U.S.
• Pursue regulatory approval for mavorixafor in Europe.
• Advance the Phase 3 4WARD trial in chronic neutropenia.
• Monitor the impact of the strategic restructuring on financial performance.
