Business Segments

Neuren operates across two reportable segments: Commercial Products and Research & Development, with the majority of revenue derived from Commercial Products.

· Commercial Products — DAYBUE (Trofinetide)

The cornerstone of Neuren's commercial business is DAYBUE (trofinetide), a novel synthetic analogue of a naturally occurring brain molecule. It is the only FDA-approved treatment for Rett syndrome in patients aged two years and older, giving Neuren an effective monopoly in this indication. Revenue is generated through royalties and milestone payments from its North American commercialisation partner, Acadia Pharmaceuticals, which handles all marketing and distribution in the US and Canada. Neuren retains all rights outside North America for trofinetide.

· Research & Development — NNZ-2591 Pipeline

Neuren's R&D segment is anchored by its second drug candidate, NNZ-2591, which is being evaluated across four serious neurodevelopmental disorders:

1) Phelan-McDermid syndrome

2) Angelman syndrome

3) Pitt Hopkins syndrome

4) Prader-Willi syndrome

All six of Neuren's active programs (including trofinetide indications) have been granted orphan drug designation by the US FDA, which provides meaningful regulatory incentives and exclusivity protections.

Strategic Initiatives

Neuren's strategy is built on a clear develop-and-partner model:

· Focus on unmet needs: Target rare neurological disorders in early childhood where no approved medicines exist, qualifying programs for orphan drug status and expedited regulatory pathways such as Fast Track designation.

· Asset-light commercialisation: Rather than building its own salesforce, Neuren licenses commercialisation rights to larger pharma partners (e.g., Acadia) while retaining ex-North America rights, reducing costs and sharing risk.

· Pipeline expansion via NNZ-2591: The company is progressing Phase 2 clinical trials for NNZ-2591 across multiple indications, aiming to replicate DAYBUE's commercial success in additional rare diseases.

· Orphan drug leverage: All programs benefit from FDA orphan drug designations, which confer tax credits, fee waivers, and 7-year market exclusivity upon approval.

Analysing the Key Catalysts Behind NEU’s Sharp Decline and Recovery Phase

Key Catalysts Behind the Sharp Decline (October 2025 – March 2026): Four major setbacks triggered the decline:

1- EMA CHMP Negative Trend Vote: The European Medicines Agency's Committee for Medicinal Products for Human Use delivered a negative trend vote on Acadia Pharmaceuticals' marketing authorisation application for trofinetide (DAYBUE) for Rett syndrome, blocking European expansion and causing a 10% single-day drop on February 2, 2026.

2- Acadia Sales Guidance Downgrade: Acadia lowered its FY24 sales forecast to US$340–370 million (an 11% reduction), attributed to slower-than-expected patient additions, which reduced revenue expectations.

3- CEO Share Sale: CEO Jon Pilcher sold 398,207 shares in September 2025 after repaying a $2.8M loan, which was interpreted by some investors as a near-term caution signal and impacted sentiment.

4- NNZ-2591 Feedback Disappointment: The CEO expressed dissatisfaction with the written feedback on NNZ-2591 for hypoxic-ischemic encephalopathy and Pitt-Hopkins syndrome, resulting in an 8.6% drop following a trading halt.

Key Catalysts Behind the Recovery Phase (April 2026): Some positive developments drove the recovery:

· DAYBUE STIX Broad US Launch: Acadia confirmed DAYBUE STIX (new powder formulation) is now broadly available across the US, moving from a limited March quarter launch to wider commercial distribution, triggering rebounding shares on April 8, 2026.

· FDA Approval of Powder Formulation: The powder formulation received FDA approval in December 2025, addressing compliance issues and expanding caregiver access, which improved patient reach.

· Strong Commercial Momentum: Over 2,000 US patients were being treated with 55% 12-month retention supporting repeat revenue, and Acadia projected global sales of US$700 million by 2028, contributing to a 7.77% gain in January 2026.

· EMA Re-examination Process: Acadia plans to request re-examination of the CHMP opinion, representing a binary near-term catalyst where a reversal could restore confidence in European expansion.
