. Left untreated, molluscum contagiosum lesions may persist an average of 13 months, with reports of cases remaining unresolved for up to five years. The symptoms of molluscum contagiosum can cause anxiety, and parents frequently seek treatment due to its highly contagious nature and its impact on physical appearance.

### ZELSUVMI
ZELSUVMI (berdazimer) topical gel, 10.3% is a nitric oxide (NO) releasing agent indicated for the topical treatment of molluscum contagiosum in adults and pediatric patients one year of age and older. ZELSUVMI was developed using the proprietary nitric oxide-based technology platform, NITRICIL. ZELSUVMI’s mechanism of action against molluscum contagiosum is unknown. In vitro studies of ZELSUVMI’s active ingredient, berdazimer

sodium, have demonstrated (i) anti-pox virus activity on vaccinia virus, which is often used as a surrogate for molluscum contagiosum virus; and (ii) reduced early gene expression of molluscum contagiosum virus proteins. ZELSUVMI’s final Phase 3 clinical study included 891 enrolled patients treated with ZELSUVMI and demonstrated statistically significant and clinically meaningful efficacy results on both primary and secondary endpoints, a greater reduction in lesions at every measurement point, and favorable safety results during the 12-week duration. LNHC’s market research indicates physicians have highly favorable opinions about ZELSUVMI’s clinical efficacy, safety, and practicality as the first and only topical medication indicated for molluscum contagiosum that does not require in office administration by a healthcare provider. LNHC believes that. ZELSUVMI is likely to complement or represent a differing treatment regimen of current procedural treatments administered in medical settings such as cryosurgery, cantharidin application and curettage.

### Proprietary NITRICIL™ Technology Platform Overview
The NITRICIL proprietary technology platform leverages nitric oxide’s naturally occurring anti-viral, anti-bacterial, anti-fungal, and immunomodulatory potential mechanisms of action in an effort to treat a range of diseases. Nitric oxide plays a vital role in the natural immune system response against microbial pathogens and is a critical regulator of inflammation. The technology’s ability to harness nitric oxide and its multiple potential mechanisms of action has enabled the creation of a platform with the potential to generate differentiated
