About X4 Pharmaceuticals

A biopharmaceutical company, focuses on the research, development, and commercialization of novel therapeutics for the treatment of rare diseases of the immune system.What are the underlying business or industry changes driving this perspective?

The launch of XOLREMDI (mavorixafor) in the U.S. for WHIM syndrome marks the company's transition to a fully integrated commercial-stage pharmaceutical, potentially driving revenue growth through increased adoption and sales.
The acceptance of the MAA by the EMA for XOLREMDI suggests potential European market approvals and commercialization in early 2026, possibly expanding the company's revenue streams through international market presence.
Strategic international partnerships with companies like Norgine and taiba rare offer potential regulatory and commercial milestone payments, alongside tiered royalties, which could significantly boost revenue as approvals are obtained in additional regions.
The progress and promising results from the Phase II trial for mavorixafor in chronic neutropenia, and the initiation of the global pivotal Phase III 4WARD trial, indicate potential future revenue expansion if approved, targeting a much larger patient population.
The recent strategic restructuring anticipated to reduce annual spending by $30 million to $35 million could improve net margins and extend the company's financial runway, potentially leading to enhanced profitability following increased sales.

X4 Pharmaceuticals Future Earnings and Revenue Growth

Assumptions

How have these above catalysts been quantified?

Analysts are assuming X4 Pharmaceuticals's revenue will grow by 270.5% annually over the next 3 years.
Analysts are not forecasting that X4 Pharmaceuticals will become profitable in next 3 years. To represent the Analyst Price Target as a Future PE Valuation we will estimate X4 Pharmaceuticals's profit margin will increase from -1464.6% to the average US Biotechs industry of 15.9% in 3 years.
If X4 Pharmaceuticals's profit margin were to converge on the industry average, you could expect earnings to reach $20.6 million (and earnings per share of $3.44) by about May 2028, up from $-37.4 million today. However, there is a considerable amount of disagreement amongst the analysts with the most bullish expecting $71.8 million in earnings, and the most bearish expecting $-100.0 million.
In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 29.7x on those 2028 earnings, up from -0.7x today. This future PE is greater than the current PE for the US Biotechs industry at 20.4x.
Analysts expect the number of shares outstanding to grow by 3.41% per year for the next 3 years.
To value all of this in today's terms, we will use a discount rate of 10.83%, as per the Simply Wall St company report.

Risks

What could happen that would invalidate this narrative?

The ultrarare nature of WHIM syndrome could limit the market size and impact future revenues, as there may be a finite number of patients who require treatment.
Reliance on successful international regulatory approvals (e.g., EMA) introduces uncertainties that could delay market expansion and hinder revenue growth outside the U.S.
The focus on a single product, mavorixafor, heightens the risk related to product-specific setbacks, such as regulatory or clinical trial failures, which could adversely affect future revenue streams and earnings.
The high R&D and SG&A expenses relative to current sales indicate ongoing net losses, which could impact financial sustainability and necessitate further capital raising, potentially diluting shareholders and affecting net margins.
Any delays or issues in fully enrolling and successfully completing Phase III trials for chronic neutropenia could postpone revenue from this larger market opportunity, significantly impacting projected earnings.

Valuation

How have all the factors above been brought together to estimate a fair value?

The analysts have a consensus price target of $75.0 for X4 Pharmaceuticals based on their expectations of its future earnings growth, profit margins and other risk factors. However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $120.0, and the most bearish reporting a price target of just $45.0.
In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be $130.0 million, earnings will come to $20.6 million, and it would be trading on a PE ratio of 29.7x, assuming you use a discount rate of 10.8%.
Given the current share price of $4.35, the analyst price target of $75.0 is 94.2% higher.
We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
