Insights

Ligand's strategic restructuring of Pelthos creates value through a $50M merger with Channel, securing both 13% royalties and equity in an FDA-approved product.

The merger between Ligand's subsidiaries and Channel Therapeutics represents a shrewd value-extraction strategy that exemplifies Ligand's capital-efficient business model. Rather than funding the full commercialization of ZELSUVMI internally, Ligand has structured a deal that provides $50 million in fresh capital while maintaining both 13% royalty rights and significant equity exposure through an $18 million investment in the combined entity.

This transaction demonstrates Ligand's core competency in asset development and monetization. They acquired Pelthos, incubated ZELSUVMI through FDA approval, and are now leveraging that regulatory success into a structured deal with multiple value streams. For investors, this creates a derisked exposure to ZELSUVMI's commercial potential while freeing Ligand's resources for other opportunities.

The molluscum contagiosum market represents a substantial commercial opportunity given its high prevalence (16.7 million affected individuals in the US) and ZELSUVMI's unique positioning as the first at-home prescription treatment. The infection's characteristics—visible lesions causing social stigma, potential for household spread, and prolonged duration—create strong treatment motivation among patients/caregivers.

Most significantly, this transaction follows Ligand's established pattern of creating multiple shots on goal via diversified royalty streams rather than assuming full commercial execution risk. The summer 2025 closing timeline provides near-term catalysts as the transaction progresses toward completion.

Ligand orchestrates a capital-efficient exit for Pelthos while maintaining significant upside through royalties and equity, maximizing shareholder value with minimal downside.

This transaction represents a masterclass in financial engineering that optimizes Ligand's capital allocation while maintaining substantial economic interest in ZELSUVMI. By contributing the Pelthos assets to a public vehicle with $50 million in fresh capital, Ligand accomplishes several financial objectives simultaneously:

First, they secure the necessary commercialization funding without diluting existing Ligand shareholders or assuming execution risk. The $32 million from Murchinson's investor group plus Ligand's $18 million commitment provides adequate runway for ZELSUVMI's launch.

Second, they create a dual-stream value capture mechanism through both the 13% royalty arrangement and equity appreciation potential. This structure effectively gives Ligand participation in commercial success while capping downside exposure—a hallmark of astute risk management.

Third, they maintain governance influence through two board seats, ensuring Ligand's interests remain represented in key strategic decisions. The transaction effectively transforms an internal development program into a more transparent, independently valued public entity with dedicated focus and resources.

The market has historically rewarded Ligand's capital-efficient business model of creating and monetizing royalty streams. This transaction fits perfectly within that framework while adding the potential for equity appreciation. For investors, this represents a positive development that enhances Ligand's financial flexibility while maintaining meaningful economic exposure to ZELSUVMI's commercial prospects.

Proposed transaction will raise $50 million in equity capital and enhance a publicly traded biopharmaceutical company focused on launching Pelthos’ ZELSUVMI™

ZELSUVMI is an FDA-designated novel drug and the first and only prescription medication approved for the treatment of Molluscum contagiosum infections administered at home by parents, patients, and caregivers

Transaction is expected to close in the summer of 2025

JUPITER, Fla. and FREEHOLD, N.J., April 17, 2025 (GLOBE NEWSWIRE) -- Ligand Pharmaceuticals Incorporated (“Ligand”) (Nasdaq: LGND) and Channel Therapeutics Corporation (“Channel”) (NYSE American: CHRO), a pioneer in the development of non-opioid pain treatment therapeutics, today announced the signing of a definitive merger agreement to combine Ligand’s wholly owned subsidiaries, Pelthos Therapeutics Inc. and LNHC, Inc. (collectively “Pelthos”) with CHRO Merger Sub Inc., a wholly owned subsidiary of Channel. The merger will be supported by $50 million in capital raised from a group of strategic investors led by Murchinson (“Investor Group”). Upon completion of the transaction, the combined company will operate under the name Pelthos Therapeutics Inc. and trade on the NYSE American exchange under the ticker PTHS.

The combined company will initially focus on accelerating the commercialization of Pelthos’ ZELSUVMI™ (berdazimer) topical gel, 10.3%, for the treatment of Molluscum contagiosum infections (“molluscum”) in adults and pediatric patients one year of age and older.1 ZELSUVMI was approved by the U.S. Food and Drug Administration (FDA) in 2024 and is the first and only prescription therapy for molluscum infections approved for use at home by patients, parents, and caregivers. The combined company will also retain Channel’s existing NaV 1.7 development programs for the treatment of various types of chronic pain, acute and chronic eye pain, and post-surgical nerve blocks. An update on Channel’s animal efficacy study for its eye pain program will be forthcoming.

“This transaction presents a compelling opportunity to launch a commercial-ready product, with significant financial backing from Murchinson, that has the potential to deliver both near and long-term value to our shareholders,” said Todd Davis, CEO of Ligand. “We executed a complex restructuring to acquire the Pelthos assets, incubated the technology that became ZELSUVMI, achieved FDA approval for this first-in-class medication, and assembled a world-class team, to bring this therapy to market. Our ability to identify highly differentiated assets and execute customized transactions to maximize their value with equity and royalty rights distinguishes Ligand’s business model and value creation strategy.”

Frank Knuettel II, CEO of Channel Therapeutics, commented, “We are very excited about the merger with Pelthos. We have performed extensive due diligence on the ZELSUVMI market opportunity and their team and operations, and we believe this is an extraordinary opportunity for current Channel shareholders. Strategically, it provides the potential for near-term revenue generation from an FDA-approved drug, the opportunity to advance Channel’s existing NaV 1.7 programs, and expanded capitalization from strong, long-standing investors.”

Molluscum contagiosum is a poxvirus and one of the most common skin infections seen by dermatologists, pediatric dermatologists, and pediatricians, afflicting an estimated 16.7 million people in the United States. 2,3 Molluscum infections spread to others through contact with infected persons or contaminated objects like towels, toys, furniture, swimming pools, and other surfaces. Children are the most vulnerable to molluscum infections. Adults with weakened immune systems or who are sexually active with a molluscum-infected partner are also particularly vulnerable. Molluscum infections present with raised, flesh-colored or red bumps that can appear anywhere on the body, including the face, hands, trunk, genitals, back of the knees, armpits, and other sensitive areas. People with molluscum may suffer discomfort from itching, secondary bacterial infections from scratching, or atopic dermatitis, as well as immense social stigma from having visible molluscum lesions, which typically last for months and frequently last for years.

Scott Plesha, CEO of Pelthos, added, “There is a significant unmet medical need for an easy-to-use, safe, and efficacious treatment option for molluscum that can be applied by patients, parents, or caregivers at home via prescription. We believe ZELSUVMI will complement pediatric and adult dermatologists’, general pediatricians’, and all other health care providers’ current efforts to treat molluscum while reducing the need for repeated invasive in-office procedures and the associated wait times needed to treat this highly infectious disease. Having commercialized both dermatology and pain management products, I am excited to lead the combined company into this next growth phase.”

Transaction Details
Under the terms of the merger agreement, Channel will acquire 100% of the issued and outstanding equity interests of Pelthos, and will change its name to Pelthos Therapeutics Inc. In connection with the transaction, Ligand has agreed to invest $18 million in the combined company and the Investor Group has agreed to invest $32 million for a total of $50 million.

Upon completion of the transaction, Mr. Plesha will become CEO of the combined company and Mr. Knuettel will become CFO. The Board of Directors will consist of Mr. Plesha, two independent directors, Peter Greenleaf and Matt Pauls, two board members appointed by Ligand, and an additional two independent directors who are reasonably acceptable to Murchinson, both of whom are current Channel board members.

The transaction is expected to close in the summer of 2025, subject to customary closing conditions.
