🧬 1. Asset and Indication Assumptions
The model begins with a structured set of product and indication assumptions.
Users can configure:

• Asset or molecule name
  
• Therapeutic indication
  
• Development phase
  
• Therapeutic area
  
• Small-molecule or biologic classification
  
• Target patient population
  
• Diagnosed and eligible patients
  
• Addressable market
  
• Expected market penetration
  
• Treatment duration
  
• Dosing and unit assumptions
  
• Wholesale acquisition cost
  
• Launch year
  
• Approval year
  
• Patent expiry year
  
• Exclusivity period
  
• Commercial uptake assumptions
  
• Pricing growth
  
• Market-share progression
  
• Loss-of-exclusivity assumptions
  

The module allows the commercial forecast to reflect the specific characteristics of the asset instead of relying on a generic top-down revenue growth rate.

🧪 2. Phase-Transition Probability Engine
Clinical-stage pharmaceutical assets carry material technical and regulatory risk. The model therefore applies phase-specific probability assumptions before calculating risk-adjusted value.
The probability engine covers:

• Phase 1 to Phase 2 transition
  
• Phase 2 to Phase 3 transition
  
• Phase 3 to regulatory filing
  
• Filing to approval
  
• Cumulative probability of success
  
• Therapeutic-area-specific probability assumptions
  
• Current development-stage selection
  
• Scenario adjustments to probability of success
  
  

The model calculates a cumulative probability of success based on the selected development stage and relevant transition probabilities.

These probabilities flow directly into the risk-adjusted cash-flow calculation. They are not presented only as separate reference statistics.

This allows users to compare:

• Unadjusted commercial value
  
• Probability-adjusted commercial value
  
• Development-stage risk
  
• Changes in value following clinical advancement
  
• Upside or downside from alternative probability assumptions
  
  

📈 3. Patient-Based Revenue Forecast
The revenue build translates epidemiological and commercial assumptions into annual product sales.
The model considers:

• Target patient population
  
• Eligible patient percentage
  
• Diagnosed or treated population
  
• Market penetration
  
• Product uptake curve
  
• Units per patient
  
• Treatment duration
  
• Gross price per unit
  
• Annual price growth
  
• Commercial launch timing
  
• Peak penetration
  
• Peak sales timing
  
• Competitive and lifecycle erosion
  
• Patent-expiry timing
  

A structured uptake curve models the progression from launch to peak penetration.

The resulting patient volumes and pricing assumptions are used to calculate:

• Treated patients
  
• Units sold
  
• Gross price per unit
  
• Gross product revenue
  
• Net price per unit
  
• Net product revenue
  
• Peak gross sales
  
• Peak net sales
  
  

💰 4. Detailed Gross-to-Net Bridge
The model includes a comprehensive gross-to-net analysis that converts gross WAC revenue into net revenue.

Instead of using a single generic discount percentage, the bridge separates the major deductions affecting pharmaceutical revenue.

The model includes:

• Commercial payer rebates
  
• Medicaid rebates
  
• Inflation-related rebate assumptions
  
• 340B programme discounts
  
• GPO and wholesaler fees
  
• Distribution fees
  
• Medicare Part D manufacturer obligations
  
• Co-pay assistance
  
• Patient-support programme costs
  
• Bad-debt provisions
  
• Product returns and reserves
  
• Other applicable gross-to-net deductions
  

Each component can be driven by:

• Payer mix
  
• Channel-specific assumptions
  
• Applicable discount percentages
  
• Annual trend assumptions
  
• Product lifecycle
  
• Competitive pressure
  
• Negotiation exposure
  

The gross-to-net module calculates:

• Gross WAC revenue
  
• Individual deduction amounts
  
• Total gross-to-net deductions
  
• Net revenue
  
• Net price per unit
  
• Net-to-gross percentage
  
• Annual net-to-gross trend
  

Supporting charts show how the deduction mix and net-to-gross ratio change throughout the forecast period.

🏛️ 5. IRA Medicare Negotiation and MFP Analysis
The model includes a dedicated module for analysing the potential financial impact of the Medicare Drug Price Negotiation Program.
The framework distinguishes between:

• Small-molecule products
  
• Biologic or large-molecule products
  

The selected molecule type drives a configurable negotiation eligibility timeline.
The module presents the sequence from:

• Product approval
  
• Years since approval
  
• Potential eligibility
  
• CMS selection
  
• Negotiation period
  
• Maximum Fair Price effective year
  

The model also includes configurable exclusion or delay assumptions for circumstances that may affect applicability.
The Maximum Fair Price analysis compares:

• A configurable statutory ceiling benchmark
  
• A negotiated discount from the applicable price
  
• The resulting lower-price outcome
  
• The counterfactual price without negotiation
  
• The post-negotiation net-price trajectory
  

The MFP-adjusted price flows directly into:

• Net revenue
  
• Commercial cash flow
  
• Risk-adjusted cash flow
  
• rNPV
  
• Sensitivity analysis
  
• Executive dashboards
  

This allows users to assess the potential valuation impact of:

• Earlier or later negotiation
  
• Different MFP discounts
  
• Alternative eligibility assumptions
  
• Molecule classification
  
• Medicare exposure
  
• Changes in payer mix
  

All legal, regulatory and pricing assumptions remain editable because the applicable requirements and guidance must be independently verified for each asset and valuation date.

📉 6. Patent Expiry and Loss-of-Exclusivity Erosion
The commercial forecast includes a patent-cliff and loss-of-exclusivity module.
The model identifies the expected patent or exclusivity expiry year and applies a configurable post-LOE erosion curve.
Different erosion profiles can be selected for:

• Small-molecule products facing generic competition
  
• Biologic products facing biosimilar competition
  

The module models:

• Pre-expiry sales
  
• Patent-cliff timing
  
• Initial post-LOE revenue decline
  
• Continuing price erosion
  
• Continuing volume erosion
  
• Remaining post-LOE revenue
  
• End-of-forecast product value
  

This prevents the valuation from applying an inappropriate perpetual-growth assumption beyond the economically relevant product lifecycle.

💸 7. Risk-Adjusted Cash-Flow Engine
The rNPV engine converts the commercial forecast into annual probability-adjusted free cash flow.
The calculation includes:

• Gross revenue
  
• Gross-to-net deductions
  
• Net revenue
  
• Cost of goods sold
  
• Gross profit
  
• Research and development expenditure
  
• Clinical development costs
  
• Regulatory and filing expenditure
  
• Selling, general and administrative costs
  
• Commercial launch expenditure
  
• Operating profit
  
• Taxes
  
• Unlevered free cash flow
  
• Cumulative probability of success
  
• Probability-adjusted free cash flow
  
• Discount factors
  
• Present value of annual cash flows
  

The model separates commercial opportunity from clinical-development risk, giving users visibility over both the unadjusted project economics and risk-adjusted asset value.
