ANI Pharmaceuticals (ANIP) Q2 2025: Cortrophin Gel Guidance Raised 21% as Rare Disease Momentum Accelerates

August 8, 2025 | By EarningsIQ Research

Rare disease outperformance drove a second guidance hike, with Cortrophin Gel now expected to deliver 63% to 66% annual growth and anchor more than half of company revenues in the back half. Broad-based demand, new presentations, and sales force expansion are driving market expansion well beyond historical peaks, while generics and retina face mixed but stable outlooks. Investors should watch for rare disease margin leverage and the pace of prescriber adoption as ANIP’s business mix shifts further toward specialty assets.

Summary

• Rare Disease Expansion: Cortrophin Gel’s adoption and prescriber base growth are driving multi-year revenue visibility.
• Operational Leverage: U.S.-centric supply chain and sales force productivity improvements bolster margin and reduce tariff risk.
• Guidance Reset: Raised full-year targets reflect accelerating rare disease momentum, offsetting retina access headwinds.

Performance Analysis

Q2 marked a record quarter for ANIP, with rare disease and generics both contributing to outsized top-line growth. Cortrophin Gel revenues surged, up 66% year-over-year and 54% sequentially, underpinned by expanded sales coverage and the successful launch of a pre-filled syringe format that now accounts for 70% of new patient starts. The rare disease segment, now the company’s growth engine, represented 57% of expected second-half revenues, reflecting a clear shift in business mix.

The retina portfolio delivered steady performance but remains weighed by persistent Medicare access challenges, prompting a $10 million reduction in full-year retina guidance. The generics business posted solid mid-teens growth, supported by new launches like Prucalopride, though management expects a sequential decline in the second half as exclusivity lapses and competitive pressures intensify. Gross margin climbed above 64%, driven by rare disease mix and temporary generics exclusivity, but is expected to normalize as the product mix evolves.

• Rare Disease Outperformance: Cortrophin Gel’s record demand and high new prescriber rates signal durable expansion potential.
• Retina Drag: Medicare funding gaps continue to limit access and have been conservatively reflected in updated guidance.
• Generics Normalization: First-half strength is expected to moderate as exclusivity benefits fade and competition rises.

Overall, ANIP’s business model is rapidly tilting toward specialty rare disease assets, with operational discipline and U.S.-based manufacturing providing resilience amid macro and regulatory uncertainty.

Executive Commentary

Strategic Positioning

1. Rare Disease Franchise Scaling

Cortrophin Gel’s momentum is the centerpiece of ANIP’s strategy, with the expanded sales force, new product presentations, and multi-specialty targeting driving both patient and prescriber growth. The asset’s addressable market is expanding as more than half of prescribers are new to ACTH therapy, and management expects continued penetration across neurology, nephrology, rheumatology, and newer areas like ophthalmology and pulmonology. The pre-filled syringe, launched in April, has rapidly become the dominant format, improving patient adherence and physician convenience.

2. Retina Portfolio: Navigating Access Challenges

The retina franchise (Illuvian and Utique) is stable but constrained by Medicare patient support funding gaps, which have not resolved as previously hoped. While the New Day trial generated positive feedback and may support earlier use of Illuvian in diabetic macular edema (DME), these benefits are expected to accrue over the longer term. Management’s revised guidance assumes no near-term improvement in Medicare access, reflecting a conservative stance amid ongoing funding uncertainty.

3. Generics: Launch-Driven Growth, Competitive Headwinds

ANIP’s generics business delivered strong first-half growth, aided by the launch of Prucalopride with 180-day exclusivity. However, management expects a step-down in the second half as competition increases and exclusivity expires. The segment remains a cash generator, but its relative contribution will decline as rare disease assets scale.

4. Margin Structure and U.S. Manufacturing Moat

ANIP’s U.S.-centric supply chain and manufacturing base (over 90% of revenue from U.S.-made goods) create a buffer against tariff and geopolitical risk. Management is focused on procurement optimization and leveraging manufacturing scale to support mid-60s gross margins as the business mix shifts further toward high-value specialty assets.

5. Capital Allocation and Business Development Discipline

With cash generation strong and leverage declining, management is building a war chest for disciplined business development, particularly in rare disease. There is no rush to deploy capital, with the focus on accretive, strategic assets that complement the existing portfolio. Debt paydown is a secondary priority, with cash currently earning interest as a hedge against outstanding debt.

Key Considerations

ANIP’s Q2 results underscore a business model in transition, with rare disease momentum offsetting legacy headwinds and operational risks. Investors should focus on the following:

Key Considerations:

• Cortrophin Gel Uptake: New prescribers, expanded indications, and the pre-filled syringe are driving broad-based adoption and market expansion.
• Retina Portfolio Drag: Medicare access challenges remain unresolved, limiting near-term upside for Illuvian and Utique.
• Generics Volatility: Launch-driven spikes are temporary, with increased competition expected to pressure second-half results.
• Margin Evolution: Rare disease mix and U.S. manufacturing are lifting margins, but normalization is expected as generics exclusivity fades.
• Disciplined Capital Allocation: Management is prioritizing organic growth and targeted rare disease BD over immediate M&A or debt reduction.

Risks

Medicare funding gaps for retina drugs remain a material risk, potentially capping segment growth until policy or funding changes. Competitive pressures in generics could accelerate margin compression if new entrants outpace expectations. Long-term, payer scrutiny of high-cost rare disease therapies could pressure net pricing, though management sees a benign environment for now. Litigation outcomes, such as the CG Oncology royalty dispute, add further uncertainty but are not currently material to guidance.

Forward Outlook

For Q3 and Q4 2025, ANIP guided to:

• Sequential growth in Cortrophin Gel revenues, supporting full-year rare disease revenue of $322 million to $329 million.
• Retina franchise revenue of $87 million to $93 million, assuming no improvement in Medicare access.

For full-year 2025, management raised guidance:

• Total net revenue of $818 million to $843 million (33% to 37% growth).
• Adjusted non-GAAP EBITDA of $213 million to $223 million (37% to 43% growth).
• Adjusted non-GAAP EPS between $6.98 and $7.35.

Management emphasized continued investment in commercial execution, evidence generation, and operational efficiency to sustain rare disease momentum and margin expansion.

• Rare disease mix will anchor margin and growth trajectory.
• Retina guidance is conservatively set given unresolved access headwinds.

Takeaways

ANIP’s rare disease franchise is now the primary value driver, with Cortrophin Gel’s rapid adoption and prescriber expansion supporting a multi-year growth runway. Margin structure is benefiting from specialty mix and U.S. manufacturing, while generics and retina face headwinds that are being actively managed. Capital allocation discipline and operational leverage provide downside protection as the business transitions further from legacy generics to specialty therapeutics.

• Rare Disease Traction: Cortrophin Gel’s outperformance and prescriber base expansion validate management’s specialty pivot and raise long-term revenue visibility.
• Margin and Mix Shift: U.S.-centric supply and rare disease growth are driving sustainable margin gains, but generics normalization will test cost discipline.
• Watch for Retina Recovery: Resolution of Medicare access issues or further evidence generation for Illuvian could unlock upside, but guidance is prudent for now.

Conclusion

ANIP’s Q2 results confirm a successful pivot toward rare disease, with Cortrophin Gel anchoring growth and margin expansion. Operational discipline and a U.S.-centric supply chain provide resilience, while management’s conservative guidance for challenged segments underscores a focus on execution and risk management.

Industry Read-Through
