Scenario Planning in Gross-to-Net Forecasting
July 2025 | Breakaway Technologies Blog
No Gross-to-Net (GTN) forecast is truly complete until someone inevitably asks:
“Well, what about this scenario?”
At Breakaway Technologies, we know that a question is more than a curiosity—it’s a critical strategic driver. Scenario planning enables life sciences companies to rapidly model and respond to uncertainty across the commercial and regulatory landscape. The ability to generate and compare multiple forecast versions using 75–80% of the same assumptions—and adjusting the remaining 20–25% to reflect specific market or product-level changes—all in under a day, turns forecasting from a compliance necessity into a competitive advantage.
Why Scenario Planning Matters in GTN Forecasting
Most GTN forecasts operate at the brand, payer segment, and time period (monthly or quarterly) level, delivering metrics like:
- Utilization Rate
- Discount Rate
- Accrual Rate
Analyzing these metrics across different scenarios allows financial controllers to project liabilities more accurately. Brand teams gain insight for promotional planning. Contracting teams can arm themselves with data-driven justifications for payer negotiations.
But the real power comes from flexibility. A robust forecasting platform—like Breakaway’s Gross-to-Net SaaS solution—lets you clone a base forecast and layer on macroeconomic shifts, legislative changes, or product-specific variables to inform rapid decision-making across the enterprise.
Example Scenarios: Macro and Micro Perspectives
Macro-Level Forecasting Scenarios
- Inflation Reduction Act (IRA) and Industry Funding Fee (IFF):
These policies reshape the Medicare Part D landscape and introduce new discount structures that can erode profitability unless modeled proactively. - Supplemental Medicaid Expansion Across States:
Slower reimbursement cycles introduce lag effects that distort trend lines unless modeled accurately. - Commercial PBM Shifts:
Changes to rebate structures—base, admin fees, tiered rebates, or price protections—may require forecasting at the contract or even transaction level.
Micro-Level Forecasting Scenarios
- NDC Portfolio Optimization:
Introducing a new NDC with higher WAC and better patient experience could drive sales—but also shift rebate dynamics and cannibalize volume. - Delivery Method & Dosage Changes:
Variations in dosage forms may alter the GTN profile, shifting erosion and uptake curves and impacting accrual estimates. - Therapeutic Area Migration:
Moving from hematology to oncology changes volume assumptions, fee fragmentation, and margin structures—requiring re-baselining of forecasts. - Inventory Visibility:
Factoring in wholesaler and specialty pharmacy inventory improves liability projections and pipeline awareness.
Preparing for Multiple Futures
Scenario planning is about more than reacting—it’s about anticipating. Whether you’re:
- Testing a new pricing strategy
- Preparing for upcoming regulatory shifts
- Adding new products or delivery methods
- Reworking your forecast granularity to account for evolving rebate structures
…you need a platform that lets you pivot quickly and calculate impact with confidence.
Breakaway’s Take
Our Detailed Forecast module was built for this. It empowers GTN teams to model “what ifs” across all levels of granularity—fast. And it allows FP&A teams to become strategic advisors, not just data reporters.
The future is uncertain. Your forecast doesn’t have to be.
