Neurocrine Biosciences (NBIX) Q2 2025: Krenesiti Revenue Triples, Diversifying Growth Beyond Ingresa

July 30, 2025 | By EarningsIQ Research

Krenesiti’s rapid commercial ramp, with sales tripling in Q2, signals a new era for Neurocrine’s top line, as diversification beyond Ingresa takes hold. Strategic payer access investments are fueling prescription volume gains, though price headwinds will weigh on near-term revenue. Pipeline momentum and commercial execution set the stage for a broader CNS leadership push into 2026 and beyond.

Summary

• Blockbuster Potential Accelerates: Krenesiti’s launch outpaces internal forecasts, reshaping Neurocrine’s growth profile.
• Volume-Driven Ingresa Growth: Expanded access and payer contracting drive prescription share, but at the expense of near-term net price.
• Pipeline Maturity in Focus: Multiple late-stage studies and new biologics signal a transition to a multi-modality CNS enterprise.

Performance Analysis

Neurocrine delivered a strong Q2, underscored by diversifying revenue streams as Krenesiti, congenital adrenal hyperplasia (CAH) therapy, posted $53 million in sales, up from $15 million in Q1, and Ingresa, tardive dyskinesia (TD) treatment, contributed $624 million. Krenesiti’s rapid adoption reflects broad prescriber enthusiasm and high reimbursement rates, with over 75% of prescriptions covered. Ingresa’s growth story continues, driven by record new patient starts and increased market share in the BMAT-2 inhibitor class, but net revenue growth is now shaped by deliberate payer contracting that expands access but compresses realized price.

While volume gains are robust across both key franchises, Neurocrine is navigating pricing headwinds on Ingresa due to mid-year Medicare formulary expansions that increased coverage by 25 points in just two quarters, now reaching about 70% of Medicare TD lives. This strategy positions Ingresa for future volume and share gains but brings a negative 5% price impact for the year, concentrated in the back half. Operating expenses are rising to support commercial momentum and pipeline advancement, but management expects SG&A leverage to improve in the second half. The company’s $1.8 billion cash position provides ample runway for R&D and business development priorities.

• Krenesiti’s Early Traction: Broad prescriber base and steady patient starts, not a bolus effect, underpin sustainable launch momentum.
• Ingresa’s Market Access Play: Expanded Medicare coverage drives prescription share but weighs on net pricing near term.
• Cash Flow and Investment Capacity: Strong balance sheet supports late-stage pipeline and potential for shareholder returns.

Overall, Q2 marked a strategic inflection as Neurocrine’s multi-product model gains real-world validation, with commercial and pipeline execution tightly aligned to long-term CNS leadership ambitions.

Executive Commentary

Strategic Positioning

1. Krenesiti Launch Validates Commercial Model

Krenesiti, CAH therapy, is demonstrating blockbuster potential with rapid uptake, high reimbursement, and broad adoption across pediatric and adult endocrinologists. Early data suggest that most prescribers have only initiated one or two patients, indicating significant runway for future penetration as awareness and comfort grow. The launch is not reliant on a bolus of pent-up demand, but rather reflects steady, sustainable patient acquisition—critical for long-term trajectory.

2. Ingresa Access Investments Shift Growth Dynamics

Neurocrine’s market access strategy for Ingresa is driving prescription share gains, especially in Medicare, now covering 70% of eligible TD lives. However, these rebate-driven contracts lower near-term net price, with a negative 5% full-year pricing impact, mostly in H2. This trade-off is intentional: sacrificing short-term revenue for long-term volume, share, and competitive positioning as the IRA (Inflation Reduction Act) environment approaches.

3. Pipeline Execution and Modality Expansion

The company is advancing multiple late-stage programs, including phase three studies for Osev Ampator in major depressive disorder and NBI 568 in schizophrenia. Early-stage biologics, such as NVIP-1435, a long-acting CRF1 antagonist, are entering the clinic, reflecting a deliberate push into multi-modality neuroscience. This R&D diversification is central to the company’s aim of becoming a leading CNS enterprise, with data readouts slated for late 2025 and 2027.

4. Capital Allocation and Operating Discipline

Neurocrine’s capital allocation priorities remain focused on revenue growth, R&D advancement, business development, and shareholder returns. Operating expense guidance was increased to support commercial and pipeline momentum, but management expects leverage to improve moving forward. The strong balance sheet provides flexibility to pursue both organic and external growth opportunities.

5. IRA and Competitive Positioning

With IRA-driven price negotiations looming for both Neurocrine and competitors, the company is proactively optimizing access and stickiness for Ingresa, aiming to maximize patient retention and minimize disruption when negotiated prices take effect in 2027 and 2029. Management is closely monitoring payer behavior and industry trends to adapt its strategy as the policy environment evolves.

Key Considerations

Neurocrine’s Q2 performance reflects a pivotal shift toward a balanced, multi-product growth model. Strategic investments in access and pipeline breadth are reshaping the company’s long-term opportunity set.

Key Considerations:

• Pricing-Volume Trade-Offs: Near-term revenue is pressured by rebate-driven contracting, but positions Ingresa for future share gains and stickier patient retention.
• Krenesiti’s Launch Quality: Broad, steady prescriber adoption and high reimbursement rates de-risk the path to blockbuster status.
• Pipeline Optionality: Multiple late-stage and novel modality programs provide future growth levers beyond current commercial assets.
• IRA Policy Navigation: Management is proactively positioning Ingresa for minimal disruption as Medicare price negotiations approach.
• SG&A Investment Discipline: Expense increases are targeted at commercial and pipeline momentum, with promised leverage in the back half of the year.

Risks

Pricing pressure from access investments could persist if payer dynamics worsen or if volume gains underperform expectations. The IRA’s impact on formulary access and competitive positioning is uncertain and could introduce volatility in 2027 and beyond. Pipeline execution risk remains, especially as multiple late-stage programs approach critical data readouts. Any delays or negative outcomes could affect long-term growth assumptions.

Forward Outlook

For Q3 2025, Neurocrine expects:

• Continued double-digit volume growth for Ingresa, but with lower net price realization due to expanded Medicare contracts.
• Krenesiti sales to build on Q2 momentum as prescriber base widens and awareness increases.

For full-year 2025, management refined guidance as follows:

• Ingresa net sales of $2.5 to $2.55 billion, reflecting volume growth offset by a negative 5% pricing impact.
• SG&A expense guidance increased by $25 million to support commercial execution.

Management highlighted several factors that will shape the second half:

• Strong prescription volume trends and continued market share gains for Ingresa.
• Krenesiti’s adoption trajectory and payer reimbursement rates as launch matures.

Takeaways

Neurocrine’s Q2 validates a multi-product revenue model with Krenesiti’s breakout launch and Ingresa’s resilient volume growth. Strategic access investments are sacrificing near-term price for future scale, while a robust pipeline and strong cash position support continued expansion.

• Commercial Diversification Materializes: Krenesiti’s early success reduces reliance on Ingresa and signals a new era for the company’s growth engine.
• Access Strategy Sets Up 2026: Medicare contracting may pressure 2025 revenue, but positions Ingresa for durable share and patient stickiness ahead of IRA changes.
• Late-Stage Pipeline Catalysts: Investors should watch upcoming R&D day and clinical readouts for signals on next-generation CNS assets and modality expansion.

Conclusion

Neurocrine’s Q2 marks a strategic transition, as blockbuster potential for Krenesiti and disciplined access strategies for Ingresa create a more resilient and diversified growth platform. The company’s pipeline breadth and proactive policy navigation reinforce its ambition to lead in CNS therapeutics over the next cycle.
