Negatives

• Relies on a single specialty pharmacy for distribution of VYKAT XR in the U.S., creating a dependency risk.
• Dependent on sole source suppliers for raw materials and manufacturing of VYKAT XR, which could lead to supply interruptions.

Risks

• Limited commercialization history and a history of significant losses make evaluating future success difficult.
• VYKAT XR may fail to achieve sufficient market acceptance by physicians, patients, caregivers, and healthcare payers.
• The estimated market opportunity for VYKAT XR may be smaller than anticipated, adversely affecting revenues.
• Inability to effectively execute sales and marketing strategies for VYKAT XR could hinder revenue generation.
• VYKAT XR may cause serious adverse events or side effects, potentially limiting its commercial desirability or leading to regulatory actions.
• Competition from other pharmaceutical and biotechnology companies, including those developing GLP-1 receptor therapies for PWS, could impact market share.
• Exposure to unfavorable pricing regulations, third-party reimbursement practices, or healthcare reform initiatives could limit product sales and profitability.
• Inability to obtain and maintain effective intellectual property rights for products, or challenges to existing patents, could harm competitive position.
• Risk of third parties initiating legal proceedings alleging infringement of intellectual property rights, leading to substantial costs and diversion of management attention.
• Potential for misappropriation of trade secrets, eroding competitive advantage.
• Uncertainty in obtaining regulatory approvals in foreign jurisdictions, such as EMA approval for VYKAT XR, could delay international commercialization.
• Ongoing regulatory obligations and review post-approval, with potential for significant additional expenses and penalties for non-compliance.
• Impact of U.S. healthcare regulations (e.g., Anti-Kickback Statute, False Claims Act, HIPAA, HITECH Act, Inflation Reduction Act, OBBBA) on business practices, pricing, and reimbursement.
• Stock price volatility, potential for short-selling campaigns, activist investors, and securities litigation.
• Limitations on the ability to utilize net operating loss carryforwards and other tax attributes due to ownership changes under Section 382 of the Internal Revenue Code.
• Information technology systems may fail or experience security breaches, leading to business disruptions or liability.
• Unfavorable U.S. or global economic conditions could adversely affect capital raising and overall business operations.
• Reliance on sole source suppliers and third-party manufacturers for VYKAT XR production and distribution, with risks of supply interruptions.
• Dependence on a single specialty pharmacy for VYKAT XR distribution in the U.S. exposes the company to risks if services are performed inadequately.
• Risk of facilities or third-party manufacturers' facilities becoming unavailable or inoperable due to natural disasters or catastrophic events.

Future Outlook

The company expects selling, general and administrative expenses to increase in future periods as it continues the commercialization of VYKAT XR. It believes existing cash, cash equivalents, and marketable securities, along with cash flows from operations, will be sufficient to meet working capital needs for at least the next twelve months. Long-term capital requirements will depend on the timing and success of VYKAT XR's continued commercialization. The EMA's review of the MAA for VYKAT XR is ongoing, with no guarantee of approval, which could impact international expansion plans.

Management Comments

• "We anticipate that subsequent events and developments will cause our views to change. However, while we may elect to update these forward-looking statements at some point in the future, we have no current intention of doing so except to the extent required by applicable law."
• "We believe that the facilities that we currently lease are adequate for our needs for the immediate future and that, should it be needed, additional space can be leased on commercially reasonable terms to accommodate any future needs."
• "We currently believe that these ordinary course matters will not have a material adverse effect on our business; however, the results of litigation and claims are inherently unpredictable."
• "Our management assessed the effectiveness of the Company’s internal control over financial reporting based on certain criteria established in the Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations (COSO) of the Treadway Commission in 2013. Based on this assessment, our management concluded that our internal control over financial reporting was effective as of December 31, 2025."

Industry Context

StockSavvy.ai notes that the FDA approval of VYKAT XR positions Soleno Therapeutics as a significant player in the rare disease market, specifically addressing the high unmet medical need for hyperphagia treatment in Prader-Willi syndrome. This aligns with a broader biopharmaceutical trend of focusing on orphan drug development for market exclusivity. The competitive landscape for PWS therapies is evolving, with other companies, including Aardvark Therapeutics, Bright Minds Biosciences, and Rhythm Pharmaceuticals, developing treatments, some of which involve GLP-1 receptor agonists, indicating potential future competition for VYKAT XR.

Comparison to Industry Standards

• VYKAT XR is the first treatment for hyperphagia in PWS patients approved in the U.S., providing a significant market advantage over competitors still in clinical development, such as Aardvark Therapeutics, Bright Minds Biosciences, Consynance, Harmony Biosciences, Neuren Pharmaceuticals, OT4B, Palobiofarma, and Rhythm Pharmaceuticals.
• The only other approved treatment for PWS in the U.S. is somatropin (growth hormone), which addresses growth failure but not hyperphagia, further highlighting VYKAT XR's unique position in addressing a core symptom.
• The company's targeted commercialization strategy, focusing on multi-disciplinary teams in university-associated hospitals and children's hospitals, is a standard and effective approach for launching rare disease drugs.

Corporate Governance

Legal Proceedings

• The company may be party to litigation and subject to claims arising in the ordinary course of business, which are inherently unpredictable.
• Defense of intellectual property claims, regardless of merit, would involve substantial litigation expense and divert management resources.
• Third parties may initiate legal proceedings alleging infringement of intellectual property rights, which could require obtaining licenses or result in monetary damages.
• The company is subject to U.S. federal and state healthcare laws and regulations pertaining to fraud and abuse and patient privacy, with potential for substantial penalties for non-compliance.
• Risk of claims, investigations, and proceedings by governmental authorities relating to allegations of non-compliance with fraud and abuse, privacy, or data protection laws.
• The company has recently been, and may in the future become, subject to short-selling campaigns and securities litigation, which are expensive and divert management attention.

Related Party Transactions

• In October 2023, the company completed a private offering of common stock and pre-funded warrants with certain investors, including entities affiliated with existing stockholders, raising approximately $60.0 million.

Stakeholder Impact

• Shareholders: Benefited from a $100.0 million accelerated share repurchase program. Face potential dilution from future equity raises and stock price volatility due to market factors and short-selling campaigns.

• Customers (Specialty Pharmacy): The company's reliance on a single specialty pharmacy for U.S. distribution creates a dependency, where inadequate performance could impact product sales and business.
• Suppliers and Manufacturers: The company's dependence on sole source suppliers and third-party manufacturers for VYKAT XR production and raw materials poses risks of supply interruptions, which could affect product availability.
