• Uncertainty regarding the achievement of milestone thresholds.
• Potential for delays or difficulties in enrolling or completing clinical studies.
• Risk that results from clinical or non-clinical studies indicate product candidates are unsafe, ineffective, or not differentiated.
• Possibility of unfavorable decisions from regulatory authorities.
• Dependence on third parties to conduct clinical studies, and to discover, develop, manufacture, and commercialize products.
• Delays or failure to achieve and maintain regulatory approvals for product candidates.
• Risks associated with patent infringement litigation initiated by the company and its partner against generic companies.
• Challenges in establishing and maintaining sales, marketing, and distribution capabilities with appropriate technical expertise and supporting infrastructure.

The company also expects continued strong cash flow from YUPELRI sales and $175 million in near-term milestone payments, with a commitment to return excess capital to shareholders.

Management Comments

• Theravance Biopharma, Inc. intends such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995.
• Ampreloxetine is an investigational product being studied for the treatment of symptomatic neurogenic orthostatic hypotension (nOH) in patients with multiple system atrophy (MSA). It has not been approved by the FDA or any other regulatory agency in the world and the safety and efficacy of ampreloxetine has not been established.
• The pre-specified subgroup analysis suggest that ampreloxetine could improve the ability to maintain an upright posture, lessen the functional burden of the disease, and could improve quality of life in MSA patients.
• If CYPRESS is positive, and the drug is approved, ampreloxetine would be the first example of a tailored treatment for nOH in this rare and fatal disease.
• Positioned to Capitalize Rapidly Upon Potential Positive Readout from Pivotal Phase 3 CYPRESS Trial.
• Ampreloxetine is well positioned to redefine expectations for patients with nOH due to MSA.
• Ampreloxetine: Potential to Transform Care in a Rare and Debilitating Disease.

Industry Context

The announcement positions Ampreloxetine as a potential breakthrough in the treatment of symptomatic neurogenic orthostatic hypotension (nOH) in Multiple System Atrophy (MSA), a rare and debilitating neurological disease with significant unmet medical needs. Current treatment options for nOH in MSA are limited, often requiring complex titration, multiple daily doses, and carrying risks like supine hypertension. Ampreloxetine, if approved, could offer a precision medicine approach with a once-daily, well-tolerated profile, potentially setting a new standard of care in a market where only about 34% of patients are currently treated.

Comparison to Industry Standards

• Current nOH treatments like Midodrine and Droxidopa often require complex titration and 3x daily dosing, whereas Ampreloxetine is being tested as a once-daily, no-titration regimen.
• Midodrine and Droxidopa carry Box Warnings for supine hypertension, a risk not observed with Ampreloxetine in clinical studies to date.
• The efficacy of existing treatments like Droxidopa and Midodrine has not been proven beyond 2-4 weeks, while Ampreloxetine's CYPRESS study design includes a 20-week assessment of durability of response.
• The average launch price for chronic neurology rare disease therapies (n=7) between 2021-2024 was $310,000, suggesting Ampreloxetine is positioned for premium pricing consistent with industry benchmarks given its orphan drug status and high unmet need.
• The target patient population of ~40,000 MSA patients with nOH in the U.S. is comparable to other rare disease markets that support blockbuster potential.

Stakeholder Impact

• Shareholders: Potential for significant value creation if Ampreloxetine is approved and successfully commercialized, driven by a strong pipeline catalyst and robust financial position.
• Patients (MSA with nOH): Potential for a first-in-class, tailored treatment that could significantly improve quality of life, reduce disability, and address a high unmet medical need.
• Healthcare Professionals: A new, potentially more effective and convenient treatment option for a challenging condition, supported by clinical data and FDA alignment.
• Employees: Continued focus on advancing in-house developed assets and potential for growth with a new commercial product.
• Regulatory Authorities: Ongoing collaborative interactions with the FDA to ensure alignment on regulatory expectations for Ampreloxetine.

Next Steps

• Topline data readout for the Phase 3 CYPRESS trial in Q1 2026.
• If CYPRESS data is positive, incorporate data into New Drug Application (NDA) and request priority review.
• Expedited NDA submission to capitalize rapidly and efficiently upon CYPRESS's potential success.
• Further information regarding the 2026 Annual General Meeting will be provided in proxy materials filed with the SEC.
• Seek EMA scientific advice/marketing authorization in Europe following CYPRESS readout.

Key Dates

Recommendation

The filing outlines a compelling investment case centered on Ampreloxetine, an investigational drug with blockbuster potential targeting a rare, high-unmet-need disease (nOH in MSA). The company boasts a strong financial position with significant cash reserves and no debt, supported by existing cash-generating assets (YUPELRI) and substantial near-term milestone payments. The Phase 3 CYPRESS trial is derisked by positive Phase 2 subgroup data and FDA alignment, with topline results expected in Q1 2026, representing a major near-term catalyst. Ampreloxetine's unique profile addresses key limitations of current therapies, positioning it as a potential standard of care with premium pricing. The clear commercial strategy and global market opportunity further enhance its attractiveness, making it a strong buy for investors seeking exposure to a high-growth biotech with a de-risked pipeline asset.
