Risks

• The company has incurred recurring losses since inception and expects to continue generating operating losses for the foreseeable future, requiring additional funding.
• The successful development and commercialization of product candidates are highly uncertain, dependent on preclinical/clinical testing, regulatory approval, and market acceptance.
• The PDUFA date for troriluzole's NDA was extended, and there is no guarantee of FDA approval or the timing thereof.
• The withdrawal of troriluzole's MAA in the EU indicates potential challenges in obtaining European regulatory approval.
• Clinical trial failures, such as those for taldefgrobep alfa in SMA, BHV-7000 in bipolar disorder, and BHV-2100 in migraine, highlight the inherent risks in drug development.
• The Note Purchase Agreement introduces significant indebtedness and covenants that could limit the company's financial and operational flexibility, including restrictions on incurring additional debt, granting liens, and making acquisitions.
• Failure to meet payment obligations under the Note Purchase Agreement could result in default and foreclosure on secured assets, including cash, equity interests, and specific troriluzole assets.
• The company's ability to generate sufficient cash flows to service its indebtedness and fund growth strategies is uncertain, potentially requiring additional dilutive equity or debt financing.
• The 2025 Knopp True-Up derivative liability exposes the company to equity price risk, where a decline in share price could result in a material cash payment obligation.
• Legal proceedings, such as the recently filed shareholder complaint, could result in significant costs and adversely impact the company's financial condition and reputation.

Future Outlook

The company expects its existing cash, cash equivalents, and marketable securities to fund operating and financial commitments for at least one year from the financial statement issuance date. Future operations will require additional funding, likely through equity or debt financings or collaborations, as significant revenue from product sales or royalties is not expected in the near future. The company plans to initiate a Phase 2 clinical trial of taldefgrobep in metabolic disease in the second half of 2025, report topline results from the first BHV-7000 focal epilepsy study in the first half of 2026, and initiate a pivotal trial of BHV-1300 in Graves' disease in the second half of 2025. A pivotal trial for BHV-1400 in IgA nephropathy is planned for 2026. The FDA's decision regarding the troriluzole NDA is expected in Q4 2025, with commercial activities for troriluzole for SCA in the U.S. expected to begin in 2025 if approved.

Management Comments

• We are committed to expeditiously providing appropriate data and/or argumentation to EMA given the evidence that warrants granting NAS, in the spirit in which the designation was intended.
• We plan to generate data within 3 months to work with EMA on next steps towards marketing authorization for troriluzole.
• We remain fully committed to a path forward for the development of troriluzole as an effective, safe and well tolerated treatment option for patients with SCA and will work towards an MAA as expeditiously as possible.
• Biohaven has begun engagement with the FDA to discuss the potential registrational path forward for taldefgrobep alfa in SMA.
• These data further support our belief that for epilepsy and MDD, BHV-7000 offers a highly favorable and differentiated tolerability profile compared to other antiseizure medicines, including a low incidence of somnolence and dizziness consistent with a lack of GABA effects.
• Based on our early results, we have entered into an expanded collaboration agreement with GeneQuantum Healthcare Co. Ltd., which provides broad target exclusivity for up to 18 ADC targets incorporating the TopoIx payload.

Industry Context

Biohaven operates in the highly competitive and capital-intensive biopharmaceutical industry, focusing on immunology, neuroscience, and oncology. The industry is characterized by long development cycles, high R&D costs, and significant regulatory hurdles. The company's strategy of leveraging proprietary drug development platforms and pursuing multiple clinical and preclinical programs across diverse therapeutic areas is common among biotech firms seeking to diversify risk and maximize pipeline potential. The recent clinical setbacks in SMA, bipolar disorder, and migraine highlight the inherent challenges and high failure rates in drug development, even for promising candidates. However, the positive real-world evidence for troriluzole in SCA and the early clinical activity of its ADC programs (BHV-1510) demonstrate the potential for breakthrough therapies. The new debt financing reflects a common industry practice for funding R&D and commercialization efforts, especially for companies without significant product revenue.

Comparison to Industry Standards

• The company's R&D spending of $372.0 million for the six months ended June 30, 2025, is substantial, reflecting the high investment required in the biopharmaceutical industry for a company with a broad pipeline of clinical-stage assets.
• The clinical trial outcomes are mixed, which is typical for the high-risk nature of drug development. For example, the failure of taldefgrobep alfa to meet its primary endpoint in SMA is not uncommon in Phase 3 trials, similar to challenges faced by other companies developing therapies for complex neurological disorders.
• The positive real-world evidence (RWE) for troriluzole in SCA, demonstrating a 50-70% slower rate of decline, is a significant finding and aligns with a growing industry trend of utilizing RWE to support regulatory submissions, as seen with other rare disease therapies.
• The early clinical activity and differentiated safety profile of BHV-1510 (TROP-2 ADC) in combination with Libtayo are encouraging, positioning it against established TROP-2 ADCs like Trodelvy (sacituzumab govitecan) from Gilead Sciences, which has shown efficacy in various solid tumors but also has known toxicities.
• The development of BHV-7000 as a Kv7 activator for epilepsy and mood disorders aims to offer an improved side effect profile (e.g., less somnolence) compared to existing anti-seizure medications, a common goal in CNS drug development to enhance patient tolerability and adherence.
• The company's focus on MoDE and TRAP degraders for immunological diseases represents an innovative approach to protein degradation, a field where companies like Arvinas and Kymera Therapeutics are also active, targeting intracellular proteins. Biohaven's focus on extracellular proteins offers a differentiated strategy.

Legal Proceedings

• On July 14, 2025, a lawsuit was filed in the United States District Court for the District of Connecticut against Biohaven Ltd. and certain of its officers, alleging federal securities law violations on behalf of a putative class of purchasers of Biohaven stock between March 24, 2023, and May 14, 2025.
• The complaint alleges misstatements or omissions in certain Biohaven press releases and SEC filings concerning the outlook for and clinical data supporting troriluzole as a treatment for SCA and BHV-7000's efficacy and clinical prospects as a treatment for bipolar disorder.
• Plaintiffs also claim individual defendants are liable for alleged securities violations through derivative control person claims under Section 20(a) of the Exchange Act.
• The company believes the allegations are without merit and plans to defend itself vigorously.

Related Party Transactions

• The company has license agreements with Yale University (Yale Agreement and Yale MoDE Agreement). The company's CEO is an inventor of patents licensed from Yale and is entitled to a specified share of glutamate product-related royalty revenues received by Yale.
• For the three and six months ended June 30, 2025, the company recorded $330K and $851K, respectively, in R&D expense related to the Yale Agreements, including certain administrative expenses.
• As of June 30, 2025, the company did not owe any amounts to Yale University.

Stakeholder Impact

• **Shareholders**: The mixed clinical trial results and PDUFA delay introduce uncertainty and potential volatility in share price. The new debt financing provides capital but also adds financial obligations and potential dilution from future equity raises. The shareholder lawsuit poses a legal and financial risk.
• **Patients**: Clinical trial failures for SMA, bipolar disorder, and migraine mean that potential new treatment options for these conditions will not be available from Biohaven's current pipeline. However, positive RWE for troriluzole in SCA offers hope for patients with this rare neurodegenerative disorder, pending FDA approval.
• **Employees**: The ongoing R&D activities and pipeline advancement indicate continued employment opportunities, but clinical setbacks could lead to program reprioritization or workforce adjustments in the long term.
• **Creditors (Oberland Capital Management LLC)**: The Note Purchase Agreement provides a secured interest in the company's cash, equity interests, and specific troriluzole assets, offering a degree of security for the debt. Revenue payments and milestone payments are tied to product success.
• **Partners (Knopp, Merus, GeneQuantum, Highlightll, Yale, BMS)**: The company's continued collaboration and licensing agreements demonstrate ongoing partnerships, but the Knopp Amendment's true-up mechanism and the Highlightll Agreement amendment show adjustments to existing terms based on performance and strategic needs.

Next Steps

• FDA decision regarding troriluzole NDA for SCA expected during the fourth quarter of 2025.
• If troriluzole is approved by the FDA, commercial activities for SCA in the U.S. are expected to begin in 2025.
• Generate data within 3 months to work with EMA on next steps towards marketing authorization for troriluzole in the EU.
• Continue engagement with the FDA to discuss the potential registrational path forward for taldefgrobep alfa in SMA.
• Optional long-term extension phase of the taldefgrobep alfa SMA trial will remain ongoing pending further data analysis and regulatory discussions.

• Continue optimizing other lead compounds for TRPM3-mediated disorders.
• Continue developing multiple MoDE and TRAP degraders toward IND and candidate nomination.
• Highlightll will pay royalties to Biohaven on China sales of BHV-8000 upon approval, following transfer of marketing authorization.

Key Dates

Recommendation

The company presents a mixed bag of results. While the net loss has narrowed and a significant debt facility has been secured, several key clinical programs (SMA, bipolar disorder, migraine, OCD) have experienced setbacks or outright failures. The delay in troriluzole's FDA decision and the withdrawal of its EU application add uncertainty to its most advanced asset. However, the positive real-world evidence for troriluzole in SCA, the promising early data from the MoDE/TRAP degraders and ADC programs (BHV-1510), and the advancement of BHV-8000 in Parkinson's disease provide some upside potential. The new debt provides liquidity for ongoing operations and pipeline development, but also introduces significant financial obligations and covenants. Given the high-risk nature of biotech, the current clinical disappointments are concerning, but the breadth of the pipeline and early successes in other areas suggest continued potential. A 'hold' recommendation is appropriate as investors should monitor the progress of the remaining promising programs and the resolution of regulatory and legal uncertainties before making further investment decisions.
