“Our commercial launch of VYKAT XR following the FDA approval in March was a truly transformative milestone for our company, and more importantly, for individuals with PWS and their physicians and caregivers,” stated Anish Bhatnagar, M.D., Chairman and Chief Executive Officer of Soleno Therapeutics.“We are pleased with the initial reception that we are seeing for VYKAT XR, reflecting its position as the very first FDA-approved therapy and the unmet need to treat the hallmark symptom of PWS: hyperphagia. I am very optimistic about our current trajectory and believe that we are well-positioned to address the needs of the PWS community while in parallel creating significant and long-lasting value for our company and our shareholders.”

Financial Results

Soleno announced FDA approval of VYKAT XR on March 26, 2025 and commercial availability in the U.S. on April 14, 2025.

Second Quarter Ended June 30, 2025 Financial Results

Soleno used $12.6 million of cash in its operating activities during the three months ended June 30, 2025, and had $293.8 million of cash, cash equivalents and marketable securities as of the end of the quarter. Cash as of the end of the second quarter excludes $230 million of gross proceeds that the company raised in July through an underwritten offering of common stock.

Product revenue, net was $32.7 million for the three months ended June 30, 2025. VYKAT XR had not been approved or commercially launched in the three months ended June 30, 2024, and accordingly, generated no revenue during this period.

Cost of goods sold was $0.7 million for the three months ended June 30, 2025 due to sales of VYKAT XR, compared to zero for the three months ended June 30, 2024. Prior to receiving FDA approval for VYKAT XR in March 2025, costs associated with the manufacturing of VYKAT XR were expensed as research and development expense. As such, a portion of the cost of inventory sold during the period was expensed prior to FDA approval.

Research and development expense was $9.1 million, which includes $2.4 million of non-cash stock-based compensation, for the three months ended June 30, 2025, compared to $12.3 million, which includes $2.7 million of non-cash stock-based compensation, in the same period of 2024. Costs in support of our June 2024 New Drug Application (NDA) submission, supply chain activities, and clinical activities decreased $2.6 million, $0.3 million, and $0.5 million, respectively, between comparable periods. Soleno incurred $0.6 million in the three months ended, June 30, 2025 towards its Marketing Authorization Application (MAA) submission in Europe, which was submitted in the second quarter of 2025. The cadence of Soleno's research and development expenditures will fluctuate depending upon the state of its clinical programs, the timing of manufacturing and other projects necessary to support the submission of its regulatory filings and activities for commercial launch.

Selling, general and administrative expense was $28.2 million, which includes $7.3 million of non-cash stock-based compensation, for the three months ended June 30, 2025, compared to $10.9 million, which includes $4.5 million of non-cash stock-based compensation, in the same period of 2024. Personnel and associated costs increased $7.6 million as Soleno hired additional employees for commercial launch and in support of its increased business activities. New program costs associated with commercial launch, including disease state education, analytics, other marketing programs, medical affairs activities and patient advocacy activities increased by $6.8 million. Soleno expects selling, general and administrative expenses to continue to increase following commercialization of VYKAT XR.

Soleno is obligated to make cash payments up to a maximum of $21.2 million to the former Essentialis stockholders upon the achievement of certain future commercial milestones associated with the sales of VYKAT XR in accordance with the terms of its 2017 merger agreement with Essentialis. The fair value of the liability for the contingent consideration payable by Soleno achieving two commercial sales milestones of $100 million and $200 million in cumulative revenue in future years was estimated to be $18.9 million as of June 30, 2025, a $1.1 million increase from the estimate as of March 31, 2025, primarily due to the approval of the NDA for VYKAT XR by the FDA in March 2025 and recording product revenue from sales of VYKAT XR subsequent to the approval. During the three months ended June 30, 2024, the estimate increased by $1.6 million from the $12.0 million estimate as of March 31, 2024.

Other income (expense), net was approximately $1.8 million in the three months ended June 30, 2025, compared to approximately $3.0 million during the three months ended June 30, 2024. The decrease was primarily due to interest expense associated with the long-term debt, partially offset by an increase in interest income driven by higher cash and cash equivalents and marketable securities during the three months ended June 30, 2025, compared to the three months ended June 30, 2024.

Net loss was approximately $(4.7) million, or $(0.09) per basic and diluted share, for the three months ended June 30, 2025, and $(21.9) million, or $(0.57) per basic and diluted share, for the same period in 2024.

About PWS
Prader-Willi syndrome (PWS) is a rare genetic neurodevelopmental disorder caused by an abnormality in the gene expression on chromosome 15. The Prader-Willi Syndrome Association USA estimates that PWS occurs in one in every 15,000 live births. The defining symptom of PWS is hyperphagia, a chronic and life-threatening condition characterized by an intense persistent sensation of hunger accompanied by food preoccupations, an extreme drive to consume food, food-related behavior problems, and a lack of normal satiety, which can severely diminish the quality of life for individuals with PWS and their families. Hyperphagia can lead to significant mortality (e.g., stomach rupture, choking, accidental death due to food seeking behavior) and longer term, co-morbidities such as diabetes, obesity, and cardiovascular disease.

INDICATION
VYKAT XR is indicated for the treatment of hyperphagia in adults and pediatric patients 4 years of age and older with Prader-Willi syndrome (PWS).

IMPORTANT SAFETY INFORMATION

Contraindications
Use of VYKAT XR is contraindicated in patients who have a known hypersensitivity to diazoxide, other components of VYKAT XR, or to thiazides.

Warnings and Precautions

Hyperglycemia
Hyperglycemia, including diabetic ketoacidosis, has been reported. Before initiating VYKAT XR, test fasting plasma glucose (FPG) and HbA1c; optimize blood glucose in patients who have hyperglycemia. During treatment, regularly monitor fasting glucose (FPG or fasting blood glucose) and HbA1c. Monitor fasting glucose more frequently during the first few weeks of treatment in patients with risk factors for hyperglycemia.

Risk of Fluid Overload
Edema, including severe reactions associated with fluid overload, has been reported. Monitor for signs or symptoms of edema or fluid overload. VYKAT XR has not been studied in patients with compromised cardiac reserve and should be used with caution in these patients.

Adverse Reactions
The most common adverse reactions (incidence ≥10% and at least 2% greater than placebo) included hypertrichosis, edema, hyperglycemia, and rash.
