DURHAM, N.C., Nov. 07, 2025 (GLOBE NEWSWIRE) -- Pelthos Therapeutics Inc. (NYSE American: PTHS), a biopharmaceutical company committed to commercializing innovative therapeutic products for unmet patient needs (“Pelthos”), today announced it has acquired the U.S. commercialization rights to Xepi® (ozenoxacin) Cream, 1%, from Biofrontera Inc. and Ferrer Internacional S.A. (the “Acquisition”). Xepi is a non-fluorinated quinolone antimicrobial indicated for the topical treatment of impetigo due to Staphylococcus aureus or Streptococcus pyogenes in adult and pediatric patients two months of age and older.

The Company has also closed on an $18 million private convertible notes financing (the “Notes”) with existing investors, including Ligand Pharmaceuticals Incorporated (Nasdaq: LGND) and a group of investors led by Murchinson Ltd (the “Investors”).

Xepi Acquisition
Under the terms of the Acquisition agreement, Pelthos will pay Biofrontera $3.0 million and Ferrer $1.2 million upfront, with additional payments based on the availability of commercial quantities of Xepi and the achievement of sales-based milestones. Pelthos will pay royalties on U.S. net sales of Xepi to Ferrer and the Investors.

“This acquisition represents an excellent investment opportunity and marks an exciting new chapter in the Pelthos growth story,” said Scott Plesha, CEO of Pelthos. “Xepi is well-positioned to address antimicrobial resistance in pediatric dermatology, and we believe it will provide physicians with an important alternative to first-line impetigo treatments. Offering another novel product to the pediatric and dermatology communities creates an increasingly favorable opportunity for Pelthos as it allows us to leverage our current commercial infrastructure to promote multiple innovative brands.”

Xepi was developed by Ferrer and Medimetriks Pharmaceuticals, Inc., and approved by the FDA in 2017. At the time of approval, Xepi was the first new novel treatment for impetigo in more than 10 years. Biofrontera has owned the U.S. rights to Xepi since 2019 but has not been actively promoting the product. Pelthos intends to re-launch Xepi in late 2026.

Impetigo is a highly contagious bacterial skin infection most often caused by Staphylococcus aureus and/or Group A Streptococcus (Streptococcus pyogenes). It affects approximately 3 million people in the U.S. every year and is most common in children ages 2 to 5.¹^,² Impetigo is among the most common bacterial skin infections seen in pediatric offices and spreads easily within families, in crowded settings, such as schools and childcare facilities.

“As bacterial resistance continues to rise, particularly to commonly used topical antibiotics like mupirocin, the need for effective alternatives in treating impetigo has never been greater,” said Lawrence A. Schachner, MD, Chair and Professor Emeritus at the University of Miami Department of Dermatology. “Xepi is one of the few treatment options for children that can act against both methicillin-resistant and mupirocin-resistant Staphylococcus aureus. We believe it is a significant therapeutic advancement for clinicians and patients facing infections that no longer respond to traditional therapies.”

Private Convertible Notes Financing
Pelthos has also closed on an $18 million convertible notes financing with the Investors. The Notes will be secured obligations of Pelthos and will bear interest at a rate of 8.5% per annum, payable quarterly in arrears. The Notes will mature on November 6, 2027, unless earlier repurchased, redeemed or converted into shares of Pelthos common stock in accordance with their terms. The Notes will be convertible at an initial conversion price of $34.442, representing the price that is the lower of (i) the Official Closing Price immediately preceding the signing of the binding agreement or (ii) the average Official Closing Price for the five trading days immediately preceding the signing of the binding agreement. The Company anticipates that the proceeds of the financing will be used to acquire and relaunch Xepi, accelerate the commercialization of ZELSUVMI, and for general working capital purposes.

In addition to the Notes, the Investors will be entitled to a low single-digit royalty on U.S. net sales of Xepi and additional milestone payments and royalties on ZELSUVMI net sales in Japan, if ZELSUVMI is approved in Japan.

“The convertible notes transaction demonstrates the ongoing confidence of our existing investors. The additional capital from this transaction allows us to add a complementary product to our portfolio, strengthens our balance sheet, and will help support the commercial growth of ZELSUVMI, our novel medicine for molluscum contagiosum,” said Frank Knuettel II, CFO of Pelthos.

Sullivan & Worcester LLP and Paul Hastings LLP served as legal counsel to Pelthos. Piper Sandler and Lake Street Capital Markets LLC served as financial advisors to Pelthos on the Notes financing, and Roth Capital Partners, LLC advised Pelthos on the Xepi acquisition. Latham & Watkins LLP served as lead counsel to Ligand. Kelley Drye & Warren LLP and Morgan, Lewis and Bockius LLP represented the group of investors led by Murchinson Ltd.
