We will also begin to evaluate diazoxide choline extended-release (DCCR) in additional high-need rare diseases as we expand our development pipeline. We have made excellent progress in 2025 and are excited for the year ahead.”

Fourth Quarter and Full-Year Ended December 31, 2025 Financial Results

Product revenue, net, was $91.7 million and $190.4 million for the three and twelve months ended December 31, 2025, respectively. VYKAT XR had not been approved or commercially launched in the three and twelve months ended December 31, 2024, and accordingly, generated no revenue during those periods.

Research and development expense was $9.6 million, which includes $2.8 million of non-cash stock-based compensation, for the three months ended December 31, 2025, compared to $21.5 million, which includes $10.1 million of non-cash stock-based compensation, in the same period of 2024. For the year ended December 31, 2025, research and development expense was $40.6 million, which includes $11.7 million of non-cash stock-based compensation, a decrease of $38.0 million compared to $78.6 million, which includes $33.7 million non-cash stock-based compensation, in the same period of 2024.

For the year, the $15.9 million decrease in expense not related to stock-based compensation was due to a reduction in pre-commercial launch costs in support of the Company’s 2024 NDA submission, supply chain, and clinical activities. These expenses decreased $7.5 million, $6.0 million, and $3.8 million, respectively. These decreases were partially offset by the Company incurring an additional $1.4 million of expense towards its MAA submission in Europe, which was submitted in the second quarter of 2025. The cadence of the Company’s research and development expenditures will fluctuate depending upon the state of its research activities, clinical programs, and the timing of manufacturing and other projects necessary to support the submission of its regulatory filings.

Selling, general and administrative expense was $40.9 million, which includes $8.7 million of non-cash stock-based compensation, for the three months ended December 31, 2025, compared to $37.3 million, which includes $19.7 million of non-cash stock-based compensation, in the same period of 2024. For the year ended December 31, 2025, selling, general and administrative expense was $132.1 million, which includes $34.1 million of non-cash stock-based compensation, an increase of $26.2 million compared to $105.9 million, which includes $66.2 million of non-cash stock-based compensation, in the same period of 2024.

For the year, personnel costs, including hiring expense and other associated headcount costs, increased $31.3 million as the Company hired additional employees in support of its commercial launch and increased business activities. New program costs associated with commercial launch activities, including disease state education, analytics, other marketing programs, medical affairs and patient advocacy activities, increased $23.4 million. Costs for international expansion increased $3.5 million. These increases were offset by the $32.1 million reduction in stock-based compensation. Selling, general and administrative expenses are anticipated to increase as the Company continues commercialization of VYKAT XR.

The Company is obligated to make cash payments of up to a maximum of $21.2 million to the former Essentialis stockholders upon the achievement of certain commercial milestones associated with the sales of DCCR in accordance with the terms of the Company’s 2017 merger agreement with Essentialis. The fair value of the liability for the contingent consideration payable by the Company upon the achievement of commercial sales milestones of $100 million and $200 million in aggregate revenue, respectively, was estimated to be $20.3 million as of December 31, 2025, a $5.5 million increase from the estimate as of December 31, 2024. The first commercial milestone was achieved in the fourth quarter 2025 and $7.0 million will be paid in the first quarter 2026.

Total other income, net, was $3.8 million for the three months ended December 31, 2025, compared to total other income, net, of $3.1 million in the same period of 2024. For the year, total other income, net, was $11.5 million for 2025, compared to $11.8 million for 2024.

For the year ended December 31, 2025, net income was approximately $20.9 million, or $0.40 per basic and $0.39 per diluted share, compared to a net loss of $(175.9) million, or $(4.38) per basic and diluted share, for the same period of 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 (diazoxide choline) extended-release tablets 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.
