Catalysts

    A clinical-stage biopharmaceutical company, focuses on developing and commercializing seralutinib for the treatment of pulmonary arterial hypertension (PAH) in the United States.
What are the underlying business or industry changes driving this perspective?
  • The successful enrollment of the PROSERA Phase III study with a targeted patient population and significant interest from patients and physicians demonstrates alignment with clinical trial goals, which could potentially lead to positive efficacy results and subsequently drive future revenue growth.
  • The collaboration with Chiesi Group to enter a global registrational Phase III study for seralutinib in PH-ILD enhances the opportunity for expanded indications and market reach, potentially impacting revenue positively.
  • The anticipation of potential first-in-class treatment status for seralutinib, with observed safety and reverse remodeling effects, implies significant market adoption potential, which could improve net margins due to competitive product positioning.
  • The extensive global enrollment for PROSERA, with high interest from international markets, indicates potential for international revenue expansion, particularly in large PAH markets like Japan, where positive trial outcomes could lead to approvals and additional market penetration.

Assumptions

How have these above catalysts been quantified?
  • Analysts are assuming Gossamer Bio's revenue will grow by 62.7% annually over the next 3 years.
  • Analysts are not forecasting that Gossamer Bio will become profitable in next 3 years. To represent the Analyst Price Target as a Future PE Valuation we will estimate Gossamer Bio's profit margin will increase from -344.8% to the average US Biotechs industry of 16.1% in 3 years.
  • If Gossamer Bio's profit margin were to converge on the industry average, you could expect earnings to reach $27.8 million (and earnings per share of $0.12) by about September 2028, up from $-138.7 million today. However, there is a considerable amount of disagreement amongst the analysts with the most bullish expecting $118.9 million in earnings, and the most bearish expecting $-214.2 million.
  • In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 78.6x on those 2028 earnings, up from -4.2x today. This future PE is greater than the current PE for the US Biotechs industry at 15.5x.
  • Analysts expect the number of shares outstanding to grow by 0.34% per year for the next 3 years.
  • To value all of this in today's terms, we will use a discount rate of 7.18%, as per the Simply Wall St company report.

Risks

What could happen that would invalidate this narrative?
  • The reliance on forward-looking statements carries inherent uncertainties, raising concerns about the reliability of anticipated financial outcomes, which could impact investor confidence and overall revenue projections.
  • The company's involvement in global clinical trials increases regulatory and operational risks, which could delay product availability and impact both potential revenue streams and net margins.
  • The high R&D expenditures relative to current revenue generation, as indicated by the $38 million in R&D expenses versus $9.9 million in quarterly revenue, could strain financial resources, affecting earnings and profitability.
  • Dependency on the successful outcome of the PROSERA Phase III trial for seralutinib is risky, with negative or inconclusive results potentially causing substantial financial setbacks and reducing projected revenues.
  • Gossamer Bio's cash runway to the first half of 2027 necessitates careful financial management, as any deviation in trial success or collaboration milestones could lead to funding gaps affecting long-term financial sustainability and net margins.

Valuation

How have all the factors above been brought together to estimate a fair value?
  • The analysts have a consensus price target of $7.75 for Gossamer Bio 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 $15.0, and the most bearish reporting a price target of just $1.25.
  • In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be $173.2 million, earnings will come to $27.8 million, and it would be trading on a PE ratio of 78.6x, assuming you use a discount rate of 7.2%.
  • Given the current share price of $2.58, the analyst price target of $7.75 is 66.7% 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.
