New biotech model

How do I model a new biotech with no products out in the market? PDUFA for first small indication is coming in august + one other later stage indication, and have a handful of early stage indications in pipeline. Co I’m looking at has no approvals rn and likely only to get 1 (my assumption; not factual)

No revenues besides grants so no COGS. Would I just skip down from revenue to OpEx? I can’t calc gross margins, R&D % of sales, etc bc of no revenue so how do I even go about modeling them? Seems like a 3 statement model is absolutely useless for new biotechs.

Based on the most helpful WSO content, here's how you can approach modeling a new biotech company with no products currently on the market:

Key Steps for Modeling a New Biotech Company:

  1. Revenue Build:

    • Detailed Revenue Build: Start by estimating the number of patients the drug is designed to treat, then layer on pricing, and estimate an adoption curve. This involves:
      • Number of Patients: Determine the incidence and prevalence of the disease.
      • Pricing: Estimate the price per treatment.
      • Adoption Curve: Project how quickly the drug will be adopted by the market.
  2. Peak Sales Estimation:

    • Peak Sales: Estimate the peak sales number and project revenue as a percentage of peak sales over time. Typically, it takes 7-8 years to ramp up to peak sales.
    • Patent Expiry: Assume a patent life (e.g., 15 years) and model revenue growth until patent expiry, followed by a sharp decline (e.g., 80% drop in the first year post-expiry).
  3. Probability Adjustments:

    • Approval Probabilities: Adjust future cash flows based on the probability of drug approval at different stages:
      • Phase II to Phase III: 50%
      • Phase III to NDA: 75%
      • NDA to Approval: 90%
    • Overall Probability: For a Phase II drug, the overall probability of reaching the market is approximately 34%.
  4. Operating Expenses (OpEx):

    • R&D Expenses: Since there are no revenues, focus on projecting R&D expenses. These are typically high for biotech companies.
    • SG&A Expenses: Estimate selling, general, and administrative expenses based on industry benchmarks or company guidance.
  5. Cash Flow Projections:

    • Discounted Cash Flows (DCF): Use a DCF model to project cash flows until patent expiry. Discount these cash flows back to the present value.
    • Risk-Adjusted Revenue: Project risk-adjusted revenue and cash flows for the period of the patent.
  6. Sensitivity Analysis:

    • Run Sensitivities: Given the high level of assumptions, run sensitivity analyses on key inputs like peak sales, time to peak sales, and approval probabilities.

Example Structure for the Model:

  • Revenue Projections:

    • Patient Population
    • Pricing per Treatment
    • Adoption Curve
    • Peak Sales Estimation
    • Probability Adjustments
  • Operating Expenses:

    • R&D Expenses
    • SG&A Expenses
  • Cash Flow Projections:

    • Risk-Adjusted Revenue
    • Discounted Cash Flows

Additional Considerations:

  • Equity Research Reports: Look at equity research reports for pre-revenue biotech companies to understand how they build revenue models.
  • Patent Expiry: Model out sales every year until key patent expiry, then assume the drug is worth nothing.
  • Consult Experts: For complex assumptions, consult specialized lawyers, accountants, or consultants.

By following these steps, you can create a robust model for a new biotech company, even in the absence of current revenues.

Meh, DCF still works. Quick way is just do a peak sales multiple for an M&A takeout down the road. 
 

But you build your top down based on epidemiology, patient pop addressable, penetration, pricing, etc., and do it every year till patent expire and give no terminal value. Then run your dcf and you’ll get a price. It’s pretty easy idk what ur on about. just be thoughtful on assumptions…

Cogs for small mol do 5% once commercialized.

Peak sales usually 5-6 years post approval.  

 

Yeah that’s why have to be thoughtful in assumptions. That’s a key driver yes. 

Quick way (ex):

Drug for disease X approved 2025, peak sales year 2031, take revs 2031 times multiple of 3 times prob of success, take NpV of this (7 years). Divide by shares and there’s a PT.
