Future Outlook

The company anticipates submitting supplemental New Drug Applications to the FDA and Type II variation requests to the European Medicines Agency in the third quarter of 2025 for setmelanotide as a treatment for acquired hypothalamic obesity. Preliminary results from the setmelanotide Phase 2 trial in Prader-Willi syndrome are expected in the second half of 2025. Enrollment in the Phase 1, Part C trial for weekly RM-718 in acquired hypothalamic obesity is expected to complete in the first quarter of 2026, along with topline data from the 12-patient Japanese cohort of the setmelanotide Phase 3 trial in acquired hypothalamic obesity and topline data from the Phase 3 EMANATE trial. Enrollment in the setmelanotide Phase 3 trial substudy in congenital hypothalamic obesity is expected to complete in the first half of 2026. A pivotal Phase 3 trial evaluating bivamelagon in acquired hypothalamic obesity is anticipated to initiate in 2026, pending regulatory alignment. The company expects its existing cash resources, combined with the net proceeds from the July 2025 offering, to fund operations for at least 24 months.

Management Comments

• Management expects operating losses to continue for the foreseeable future.
• Management believes existing cash resources, combined with the net proceeds from the July 2025 offering, will be sufficient to fund operations through at least the next twelve months from the filing of this Quarterly Report on Form 10-Q with the SEC, and for at least 24 months in total.
• Management expects cost of sales as a percentage of revenue to continue to be in a range of 10% to 12% in the foreseeable future.
• Management expects research and development costs to increase significantly for the foreseeable future as setmelanotide and other development programs progress.
• Management anticipates selling, general and administrative expenses will increase in the future to support continued and expanding commercialization efforts for IMCIVREE in the United States and the European Union, as well as increased costs of operating as a global commercial stage biopharmaceutical public company.

Industry Context

The company operates in the highly competitive biotechnology and pharmaceutical industries, specifically targeting rare neuroendocrine diseases and obesity caused by MC4R pathway diseases. The industry is characterized by rapid technological change, high R&D costs, and complex regulatory pathways. The company's focus on precision medicine for genetically-defined obesity aligns with a broader industry trend towards personalized therapies. The positive clinical trial results for setmelanotide and bivamelagon position the company favorably in the niche market of rare genetic obesities, differentiating it from general obesity treatments like GLP-1 agonists, which do not specifically restore MC4R pathway function. The successful capital raise reflects investor confidence in its pipeline and commercial strategy within this specialized segment.

Comparison to Industry Standards

• IMCIVREE is the first-ever therapy developed for patients with certain rare diseases that is approved or authorized in the United States, European Union, Great Britain, Canada, and other countries and regions, setting a new standard for treatment in these specific indications.
• The Phase 3 TRANSCEND trial for setmelanotide in acquired hypothalamic obesity is believed to be the largest and longest placebo-controlled trial to evaluate a therapy for this condition, demonstrating a commitment to robust clinical evidence comparable to leading industry players.
• Bivamelagon's Phase 2 results showing BMI reductions consistent with setmelanotide therapy in similar patient populations at comparable dosing durations suggest its potential to be a competitive oral MC4R agonist, similar to how other companies develop oral alternatives to injectable therapies.
• The company's extensive DNA database with approximately 100,000 sequencing samples for obesity research is a significant asset, comparable to large genomic initiatives undertaken by major pharmaceutical companies to identify and target rare genetic conditions.
• While the company faces competition from general obesity therapies like GLP-1 receptor agonists (e.g., Novo Nordisk's Wegovy, Eli Lilly's Zepbound), its focus on genetically-defined MC4R pathway deficiencies positions it in a distinct, less crowded therapeutic area, where existing therapies are not specifically designed to address the root cause of hyperphagia and obesity.

Corporate Governance

Legal Proceedings

• Not presently subject to any pending or threatened litigation that is believed, individually or taken together, would reasonably be expected to have a material adverse effect on the business or financial results.

Related Party Transactions

• Expenses paid directly to related parties for the three and six months ended June 30, 2025 and 2024, were immaterial.
• Outstanding payments due to related parties as of June 30, 2025 and December 31, 2024 were immaterial.

Stakeholder Impact

• **Shareholders**: Experienced dilution from the recent follow-on offering but benefit from significantly increased cash runway and positive clinical trial data, which could lead to future share price appreciation. Common stock is subordinated to Series A Convertible Preferred Stock.
• **Patients**: Potential for new and expanded treatment options with setmelanotide for acquired hypothalamic obesity and Prader-Willi syndrome, and bivamelagon for acquired hypothalamic obesity, addressing unmet medical needs in rare neuroendocrine diseases.
• **Employees**: Increased headcount to support expanding business operations and R&D programs, indicating job growth and stability. Stock-based compensation is a significant component of employee-related expenses.
• **Creditors/Lenders**: The company's improved liquidity from the capital raise enhances its ability to meet existing obligations, including the deferred royalty obligation under the RIFA.
• **Regulatory Bodies**: The company's ongoing clinical trials and planned regulatory submissions (sNDA, Type II variation) demonstrate active engagement with regulatory authorities to expand approved indications.

Next Steps

• Complete submissions of a supplemental New Drug Application to FDA and a Type II variation request to the EMA seeking approval for setmelanotide for the treatment of acquired hypothalamic obesity in Q3 2025.
• Disclose preliminary results from the setmelanotide Phase 2 trial in Prader-Willi syndrome in H2 2025.

• Announce topline data in the Phase 3 EMANATE trial evaluating setmelanotide in genetically caused MC4R pathway diseases in Q1 2026.
• Complete enrollment in the setmelanotide Phase 3 trial substudy in congenital hypothalamic obesity in H1 2026.
• Pending alignment with U.S. and European regulatory agencies, initiate a pivotal Phase 3 trial evaluating bivamelagon in acquired hypothalamic obesity in 2026.

Key Dates

Recommendation

Rhythm Pharmaceuticals is demonstrating strong operational momentum, evidenced by robust product revenue growth for IMCIVREE and significant positive clinical trial results for its pipeline assets, setmelanotide and bivamelagon. The successful $189.2 million capital raise substantially strengthens the balance sheet, providing a 24-month cash runway, which is critical for a biotech company still in its growth phase. While the company remains unprofitable, the clear path to expanding approved indications for setmelanotide and advancing new drug candidates like bivamelagon and RM-718, coupled with a solid financial foundation, presents a compelling long-term investment opportunity for investors with a higher risk tolerance seeking exposure to the rare disease and precision medicine sectors. The reduced net loss year-over-year also indicates improving financial efficiency.
