Business Overview: From Royalty Aggregator to Diversified Biopharma Investor
Ligand was founded in 1987 and initially focused on discovering and developing new drugs as a biopharmaceutical research and development company. In its early years, Ligand faced challenges in establishing its technology platforms and building its pipeline of drug candidates, experiencing setbacks in clinical trials and competition from larger pharmaceutical companies. Despite these obstacles, the company persevered and made significant progress in the 1990s and 2000s, developing partnerships with major pharmaceutical companies and adding several approved drugs to its portfolio.
A key milestone in Ligand's history was the acquisition of CyDex Pharmaceuticals in 2011, which brought the Captisol technology platform to the company. Captisol, a chemically modified cyclodextrin, is used to enhance the solubility and stability of drug molecules. Ligand has since leveraged this platform to develop numerous partnered and proprietary programs.
In 2010, Ligand acquired Metabasis Therapeutics, adding new technology platforms such as HepDirect and LTP, which are liver-targeting prodrug technologies. These platforms have been used to develop drug candidates and have been licensed to other pharmaceutical companies.
Over the years, Ligand has faced additional challenges, including patent expirations, regulatory hurdles, and competition from generic drugs. However, the company has demonstrated its resilience and ability to adapt to changing market conditions.
In 2007, Ligand pivoted its strategy to becoming a royalty aggregator, acquiring passive royalty interests in approved and late-stage pharmaceutical products. This shift allowed Ligand to benefit from the upside of successful drug launches without shouldering the risks and costs of drug development.
Over the years, Ligand has built an impressive portfolio of royalty-generating assets, including blockbusters like Amgen's Kyprolis, Travere's Filspari, and Verona's Ohtuvayre. In 2024, the company's royalty revenue grew by 28% year-over-year, highlighting the strength and diversification of its portfolio.
More recently, Ligand has expanded its investment strategy beyond traditional royalty acquisitions. The company now actively deploys capital through project financing deals, special situations, and equity investments in promising biopharmaceutical companies. This diversification has allowed Ligand to capture value across the entire drug development lifecycle, from early-stage research to commercial-stage products.
Financial Performance
Ligand's financial performance has been consistently strong, with the company reporting total revenue of $167.1 million in 2024, a 27% increase from the previous year. This growth was primarily driven by a 28% increase in royalty revenue, which reached $108.8 million.
For the full year 2024, Ligand reported a net loss of $4.03 million. However, the company generated strong cash flows, with operating cash flow of $97.05 million and free cash flow of $77.41 million.
In the most recent quarter (Q4 2024), Ligand reported revenue of $42.81 million, up 52% year-over-year. This growth was primarily driven by a 55% increase in royalties, led by strong performance from Filspari and newly acquired Qarziba. However, net income for the quarter declined to a loss of $31.09 million, compared to a profit of $18.23 million in Q4 2023, due to increased operating expenses, impairment charges, and fair value adjustments to partner program derivatives.
The company's profitability has also been impressive, with core adjusted earnings per share (EPS) of $5.74 in 2024, up from $4.06 in 2023. Ligand's EBITDA margin has remained healthy, averaging around 24% over the past three years.
Liquidity and Balance Sheet
Ligand's balance sheet is robust, with $256.2 million in cash, cash equivalents, and short-term investments as of December 31, 2024. Additionally, the company has access to a $125 million revolving credit facility, which can be upsized to $175 million, providing ample liquidity to pursue strategic opportunities. As of December 31, 2024, $124.4 million was available under this facility.
The company's debt-to-equity ratio is very low at 0.009, calculated as total debt of $7.11 million divided by stockholders' equity of $830.44 million. Ligand's current ratio of 8.93 and quick ratio of 8.55 indicate a strong short-term liquidity position.
Recent Developments and Key Catalysts
In 2024, Ligand achieved several notable milestones that underscore the company's ability to identify and capitalize on high-value opportunities:
1. Apeiron Acquisition: Ligand acquired Apeiron Biologics AG in July 2024, adding the royalty rights to Qarziba (dinutuximab beta) for the treatment of high-risk neuroblastoma. This transaction expanded Ligand's commercial-stage royalty portfolio and provided exposure to a product with significant growth potential.
2. Agenus Transaction: In May 2024, Ligand entered into a $75 million royalty financing agreement with Agenus to support the development of the company's key oncology programs, including the novel immunotherapy combination of botensilimab and balstilimab (BOTBAL). This deal highlights Ligand's ability to structure creative non-dilutive financing solutions for its partners.
3. Castle Creek Biosciences Investment: In February 2025, Ligand led a $75 million royalty financing to support Castle Creek's phase 3 clinical trial for D-Fi, an investigational gene therapy for the treatment of dystrophic epidermolysis bullosa (DEB). This transaction marked Ligand's first foray into the cell and gene therapy space, diversifying the company's investment portfolio.
4. Pelthos Therapeutics Launch: Ligand acquired the assets related to Novan's NITRICIL technology platform in 2023 and subsequently launched Pelthos Therapeutics, a wholly owned subsidiary focused on the commercialization of Zelsuvmi, the first and only FDA-approved treatment for molluscum contagiosum. Pelthos is expected to be a key driver of future growth for Ligand.
Technology Platforms
Ligand operates through two main technology platforms: Captisol and NITRICIL.
Captisol Technology Platform: Captisol is a patented, chemically modified cyclodextrin designed to optimize the solubility and stability of drugs. This technology has enabled FDA-approved products such as Gilead's Veklury, Amgen's Kyprolis, Baxter's Nexterone, and Acrotech Biopharma's Evomela. Ligand maintains a broad global patent portfolio for Captisol with the latest expiration date in 2033, and additional patent applications could potentially extend the expiration date to 2041. The company owns over 400 issued patents covering Captisol compositions, methods, and related technology.
Captisol sales were $30.88 million in 2024, up 9% from $28.37 million in 2023, due to the timing of customer orders. Captisol material sales represent a significant portion of Ligand's total revenue, accounting for approximately half of the company's royalty revenues.
NITRICIL Technology Platform: Acquired through the Novan acquisition in 2023, the NITRICIL platform leverages nitric oxide's naturally occurring antimicrobial and immunomodulatory effects to develop new therapies. This platform allows for tunable dosing and an adjustable drug release profile to target a broad range of indications. NITRICIL is currently utilized in the FDA-approved product ZELSUVMI.
Other Technologies: Ligand also has other technology platforms, including HepDirect and LTP, which are proprietary liver-targeting prodrug technologies, as well as the BEPro technology for nucleotide and nucleotide analog development. Additionally, Ligand owns a 31.4% stake in Primrose Bio, which owns the Pelican Expression Technology platform for recombinant protein production.
Outlook and Guidance
For 2025, Ligand has provided financial guidance that reflects the company's continued momentum. The company expects total revenue to be in the range of $180 million to $200 million, representing a year-over-year increase of approximately 17% at the midpoint. This guidance includes:
- Royalty revenue expected to be between $135 million and $140 million - Captisol sales expected to range from $35 million to $40 million - Contract revenue expected between $10 million and $20 million
Core adjusted EPS is forecasted to be between $6.00 and $6.25, up from $5.74 in 2024.
Looking further ahead, Ligand has outlined a long-term royalty receipts growth outlook of at least 22% compound annual growth rate (CAGR) from 2024 through 2029. This projection is underpinned by the company's robust commercial-stage portfolio, which includes 12 major revenue-generating assets, as well as a deep pipeline of late-stage development programs.

3. Concentration Risk: A significant portion of Ligand's royalty revenue is generated by a limited number of products, such as Kyprolis, Filspari, and Ohtuvayre. Any issues with these key assets could have a disproportionate effect on the company's overall performance.
4. Integration and Execution Risks: As Ligand continues to diversify its investment strategy, the company faces risks related to successfully integrating and managing its growing portfolio of assets, including development-stage programs and special situation investments.
Conclusion
Ligand Pharmaceuticals has evolved from a traditional royalty aggregator into a diversified biopharma investment platform, strategically deploying capital to generate a growing stream of predictable cash flows. The company's robust commercial portfolio, coupled with its expanding pipeline of late-stage development programs, positions Ligand for continued growth and value creation in the years ahead. However, the company must navigate the inherent risks associated with its business model, including reliance on partner success and concentration risk. Overall, Ligand's transformation into a diversified investment platform with a strong financial profile makes it a compelling opportunity for investors seeking exposure to the dynamic biopharmaceutical industry.
