Business Description

ORGANIZATION AND DESCRIPTION OF BUSINESS Description of Business Pelthos Therapeutics Inc. (the “Company”) is a bio-pharmaceutical company committed to commercializing innovative, safe, and efficacious therapeutic products to help patients with unmet treatment burdens. The Company currently has three U.S. Food and Drug Administration (“FDA”) approved products in its commercial portfolio, in various stages of commercialization, including ZELSUVMI TM , XEPI ® , and XEGLYZE ® . The Company is currently actively promoting one commercial product, ZELSUVMI (berdazimer) topical gel, 10.3% for the treatment of molluscum contagiosum, which was approved by the FDA in January 2024 and was commercially launched in July 2025. Berdazimer sodium is the active pharmaceutical ingredient (“API”) used in ZELSUVMI and is the backbone of the NITRICIL™ platform technology. During the fourth quarter of 2025, the Company acquired the rights to both XEPI and XEGLYZE, for the treatment of impetigo and head lice, respectively, and is preparing them for future commercialization. The Company leases its manufacturing facility, owns and operates the equipment used in the production of the ZELSUVMI API, and has the personnel, know-how, and experience to produce the API for ZELSUVMI. In addition, the Company also has rights to clinical stage assets that selectively target the sodium ion-channel known as “NaV1.7”, which has been genetically validated as a pain receptor in human physiology. A NaV1.7 blocker is a chemical entity that modulates the structure of the sodium-channel in a way to modulate the transmission of pain perception to the central nervous system. Company Background The Company was effectively formed on July 1, 2025 with the merger transaction between Channel Therapeutics Corporation (“Channel”) and LNHC, Inc. (“LNHC”). See below within this Note 1 as well as Note 3 — “Acquisition of LNHC, Inc.” for further information regarding the merger transaction between Channel and LNHC. Chromocell Therapeutics Corporation (“Chromocell”) was incorporated in Delaware on March 19, 2021. On February 21, 2024 , Chromocell completed the initial public offering of its Common Stock (the “IPO”) by issuing 110,000 shares of its Common Stock at a price of $60.00 per share. The aggregate net proceeds from the IPO were approximately $5,900 after deducting $900 in underwriting discounts and commissions and offering expenses. On November 18, 2024, Chromocell merged with and into its wholly-owned subsidiary, Channel, a Nevada corporation, pursuant to an agreement and plan of merger, dated as of November 18, 2024 for the purposes of reincorporating Chromocell in Nevada. LNHC was incorporated in the state of Delaware in September 2023 by Ligand Pharmaceuticals, Inc. (“Ligand”) and was initially formed to facilitate a transaction between Ligand and Novan, Inc. (“Novan”). On September 27, 2023, Ligand acquired certain assets of Novan, after providing debtor in possession financing and acquiring specific assets from Novan, under Section 363 of the U.S. Bankruptcy Code (a “363 transaction”). Novan was a medical dermatology company focused on developing and commercializing innovative therapeutic products for skin diseases. Through its NITRICIL technology platform, Novan developed ZELSUVMI (berdazimer gel, 10.3%), formerly named SB206, as a topical prescription gel for the treatment of viral skin infections, with a focus on molluscum contagiosum. As of the acquisition date in September 2023 by Ligand, all assets and liabilities acquired in the Novan acquisition were held by LNHC, which was a wholly owned subsidiary of Ligand, including the NITRICIL technology platform. On March 24, 2025, LNHC assigned its intellectual property portfolio related to the Novan acquisition, including the NITRICIL technology, to Ligand and entered into an exclusive license and sublicense agreement with Ligand, pursuant to which Ligand licensed to the Company the intellectual property rights necessary to make, use, sell or offer to sell ZELSUVMI for the treatment of molluscum contagiosum in humans worldwide, except for Japan. On March 24, 2025, LNHC and Ligand also entered into a master services agreement under which Ligand, or related parties, may contract with LNHC to provide API for clinical or commercial use related to the NITRICIL technology.…
