• Arm Holdings for drug discovery.
• Dolby Laboratories for pharmaceutical platforms.
• A music publisher, but for drug discoveries.

• Captisol® Technology: A modified cyclodextrin excipient used to improve the solubility, stability, and bioavailability of active pharmaceutical ingredients in drug formulations.
• OmniAb® Antibody Discovery Platform: An integrated suite of next-generation antibody discovery technologies licensed to partners for identifying novel therapeutic antibodies.
• Royalty-Generating Drug Programs: Ligand licenses various proprietary drug candidates and discovery platforms to partners, receiving milestone payments and royalties on the sales of resulting commercialized medicines.

Ligand Pharmaceuticals (LGND) primarily operates by licensing its proprietary drug discovery and development technologies to other pharmaceutical and biotechnology companies. Therefore, its major customers are other companies rather than individuals. Ligand generates revenue through license fees, milestone payments, and royalties on product sales that incorporate its technologies.

Based on their business model and recent financial disclosures, the major customer companies (or significant partners contributing to revenue through royalties) include:

• Alkermes plc (Symbol: ALKS)
  Alkermes uses Ligand's Captisol technology in its product Vivitrol (naltrexone extended-release injection for opioid and alcohol dependence).
• Amgen Inc. (Symbol: AMGN)
  Amgen utilizes Ligand's Captisol technology in its product Kyprolis (carfilzomib for multiple myeloma).
• Takeda Pharmaceutical Company Limited (Symbol: TAK)
  Takeda has historically been a significant partner for Ligand, notably with Velcade (bortezomib for multiple myeloma) which utilized Captisol. While Velcade's market dynamics have changed due to generic competition, it has been a major revenue source for Ligand for many years.

Beyond these specific examples, Ligand partners with a broad range of pharmaceutical companies, from large multinationals to smaller biotech firms, for the use of its various technology platforms such as Captisol and OmniAb (an antibody discovery platform). These partnerships result in a diverse set of licensees, all of whom can be considered customers in the context of their licensing agreements and potential future royalty payments.

The increasing success and adoption of advanced in vitro and artificial intelligence-driven antibody discovery platforms represent a clear emerging threat to Ligand Pharmaceuticals' OmniAb platform. While OmniAb relies on in vivo transgenic animal models for antibody generation, competitors like AbCellera are demonstrating highly efficient, scalable, and potentially more cost-effective approaches combining high-throughput screening with AI and machine learning. This technological shift could diminish the competitive advantage and demand for Ligand's traditional in vivo platform, potentially impacting future licensing deals and royalty streams, similar to how digital streaming services challenged traditional physical media rental.

Captisol Technology Platform

Royalties from Partnered Products

NITRICIL Technology Platform

Ligand Pharmaceuticals (LGND) is poised for future revenue growth over the next two to three years, driven by several strategic initiatives and the performance of its diverse portfolio. Key drivers include continued expansion of its royalty revenue streams from commercialized products, strategic investments in new royalty-generating assets, sustained sales of its proprietary Captisol platform, and revenue generated from contract agreements including out-licensing and milestone payments, as well as the advancement of its partnered pipeline programs.

Here are 5 expected drivers of Ligand Pharmaceuticals' future revenue growth:

1. Growth in Royalty Revenue from Commercial-Stage Products: Ligand Pharmaceuticals anticipates significant growth from its existing portfolio of commercial-stage royalty-generating assets. The company projects its long-term royalty receipts to grow at a compound annual growth rate (CAGR) exceeding 22% through 2029, with the current portfolio alone supporting an 18% royalty receipts CAGR. Key products contributing to this growth include Travere Therapeutics' Filspari, Merck/Verona Pharma's Ohtuvayre, Recordati's Qarziba, and Merck's CAPVAXIVE, all of which have recently seen strong performance and are expected to continue driving royalty income.

2. Strategic Investments and Acquisitions of New Royalty-Generating Assets: A core component of Ligand's business model is the acquisition of high-value royalty-generating assets and the funding of mid-to-late-stage drug development programs in exchange for economic rights. The company possesses substantial deployable capital, approximately $1 billion as of Q3 2025, which it intends to utilize for strategic investment opportunities and to fuel its robust business development pipeline. These future investments are expected to add at least 4% to the existing portfolio's royalty CAGR.

3. Captisol Platform Sales: Ligand's proprietary Captisol platform, designed to enhance the solubility and stability of drugs, remains a consistent revenue contributor. The company's 2025 guidance projects Captisol sales to reach $40 million. This platform supports a diverse range of approved products and continues to be relevant in drug formulation and delivery.

4. Contract Revenue from Out-licensing and Milestone Payments: Ligand generates contract revenue through various agreements, including out-licensing its technologies and achieving development and commercialization milestones with partners. Recent examples of contributions to this revenue stream include the $24.5 million income from the out-license of Zelsuvmi and a $28.6 million gain from the sale of the Pelthos business in Q3 2025. For the full year 2025, contract revenue is anticipated to be $38 million.

5. Advancement of Partnered Pipeline Programs: The progression of existing partnered drug candidates through clinical development and regulatory approvals is a key driver for future royalty streams and milestone payments. Ligand highlighted at its Investor and Analyst Day that "twelve commercial-stage programs and late-stage pipeline are expected to drive strong revenue growth over the next five years." Successful launches and FDA approvals, such as those for Ohtuvayre, CAPVAXIVE, and Filspari, directly translate into new and growing royalty revenues.

• In 2025, as part of the Pelthos transaction, Ligand received Pelthos shares valued at $44.092 million in exchange for its LNHC, Inc. business and Pelthos shares valued at $12.732 million for a bridge loan cancellation.
