Ligand Reports Third Quarter 2026 Financial Results

Third-quarter royalty revenue up 51% year-over-year to $70.3 million

Raises Full-Year 2026 Adjusted Diluted EPS Guidance to $9.50 to $9.75, from $9.00 to $9.501; Reaffirms Revenue Guidance

Conference call begins at 8:30 a.m. Eastern Time today

JUPITER, Fla., October 29, 2026 – Ligand Pharmaceuticals Incorporated (Nasdaq: LGND) today reported financial results for the three and nine months ended September 30, 2026, and provided an operating forecast and business update. Ligand management will host a conference call and webcast today at 8:30 a.m. Eastern Time to discuss the results and answer questions.

“Ligand delivered another strong quarter, with royalty revenue growing 51% year-over-year, driven by contribution from the XOMA portfolio and continued commercial momentum across our key royalty assets, including Filspari,” said Todd Davis, CEO of Ligand. “We also continued to put capital to work in differentiated assets, acquiring a royalty interest in Santen’s Ryjunea and entering into a structured financing agreement with AvenCell Therapeutics to advance its next-generation CAR-T pipeline. With a strong balance sheet and a portfolio of over 200 assets, we are well positioned to continue executing our royalty aggregation strategy, and we look forward to sharing an updated five-year outlook at our investor day on December 8th.”

Financial Results

Third Quarter 2026 Financial Results

Third-quarter 2026 results reflect continued strength in the royalty business, with royalty revenue increasing 51% year-over-year to $70.3 million, compared with $46.6 million for the prior-year period. Royalties accounted for 89% of total revenues and income in the quarter, with growth driven by the newly acquired XOMA assets and continued momentum across Ligand’s key commercial portfolio, including Travere Therapeutics’ Filspari and Merck’s Ohtuvayre.

Total revenues and income for the third quarter of 2026 were $78.7 million, compared with $115.5 million for the prior-year period, representing a decrease of 32%. The prior-year period included $53.1 million of Pelthos divestiture-related income (see Pelthos note below). Excluding that income, total revenues and income increased 26%. Captisol® sales were $7.9 million, compared with $10.7 million, reflecting the timing of customer orders. Contract revenue and income were $0.5 million, compared with $58.2 million, with the decrease primarily due to the prior-year Pelthos divestiture-related income.

Cost of Captisol was $2.7 million for the third quarter of 2026, compared with $3.8 million for the prior-year period, with the decrease primarily attributable to lower Captisol sales. Amortization of intangibles was $10.2 million, compared with $8.1 million for the prior-year period, with the increase attributable to the intangibles acquired from the XOMA acquisition. Research and development expense was $2.8 million, compared with $21.0 million for the prior-year period, with the decrease primarily attributable to a $17.8 million charge recognized in the prior-year period related to the research and development funding arrangement associated with the AVIM Therapy

1 A reconciliation of forward-looking non-GAAP adjusted earnings per diluted share to the most directly comparable GAAP measure is not available without unreasonable effort, as certain items cannot be reasonably predicted because of their high variability, complexity and low visibility. Specifically, non-cash adjustments that could be made for changes in contingent liabilities, changes in the market value of its investments in public companies, share-based compensation expense and the effects of any discrete income tax items, directly impact the calculation of our core adjusted earnings per diluted share.

royalty rights acquired in the Orchestra BioMed transaction. General and administrative expense was $72.6 million, compared with $28.4 million for the prior-year period. The increase primarily reflects transaction and integration costs and share-based compensation associated with the XOMA acquisition, as well as higher employee-related costs from the expansion of Ligand’s portfolio management and origination platform to scale its royalty portfolio. Fair value adjustments to contingent liabilities resulted in a $6.3 million loss in the third quarter of 2026, compared with a $0.5 million gain in the prior-year period. The change was primarily driven by fair value adjustments related to contingent liabilities assumed in the XOMA acquisition.

Net non-operating expense was $28.3 million for the third quarter of 2026, compared with net non-operating income of $85.8 million for the prior-year period. The change was primarily attributable to non-cash mark-to-market losses on equity-method investments and other investments, as well as net loss from short-term investments during the third quarter of 2026, compared with gains in the prior-year period.

GAAP net loss was $28.5 million, or $1.43 per share, for the third quarter of 2026, compared with GAAP net income of $117.3 million, or $5.68 per diluted share, for the prior-year period. Results for the third-quarter of 2026 included $39.5 million of pre-tax losses, consisting of a $35.7 million loss from changes in the fair value of equity-method and other investments and a $3.8 million net loss on short-term investments.

Adjusted net income was $57.5 million, or $2.67 per diluted share, compared with $63.8 million, or $3.09 per diluted share, for the prior-year period, representing decreases of 10% and 14%, respectively. The decreases were primarily attributable to the $24.5 million of Pelthos out-license income recognized in the prior-year period (see Pelthos note below) and higher general and administrative expense excluding share-based compensation and transaction and integration costs, partially offset by the 51% increase in royalty revenue. Adjusted net income is a non-GAAP financial measure. See the table below for a reconciliation of GAAP net (loss) income to adjusted net income.

Pelthos note: Prior-year results included $53.1 million of income related to Pelthos. Of that, $24.5 million was attributable to the Zelsuvmi out-license and was included in core revenues, and the $28.6 million gain on the sale was excluded. Growth rates that exclude this income compare the periods on a like-for-like basis.

Year-to-Date Financial Results

Royalty revenue for the nine months ended September 30, 2026 increased 46% to $161.3 million, compared with $110.5 million for the prior-year period, and accounted for 83% of total revenues and income. Royalty growth was primarily driven by the newly acquired XOMA assets and continued momentum across Ligand’s key commercial portfolio, including Travere Therapeutics’ Filspari and Merck’s Ohtuvayre. Total revenues and income were $194.2 million, compared with $208.4 million, representing a decrease of 7%. The prior-year period included $53.1 million of Pelthos divestiture-related income (see Pelthos note above). Excluding that income, total revenues and income increased 25%. Captisol sales were $24.6 million, compared with $32.4 million, reflecting the timing of customer orders. Contract revenue and income were $8.3 million, compared with $65.5 million, with the decrease primarily due to the prior-year Pelthos divestiture-related income.

Cost of Captisol for the nine months ended September 30, 2026 was $9.1 million, compared with $11.6 million for the prior-year period, with the decrease primarily attributable to lower Captisol sales. Amortization of intangibles was $26.4 million, compared with $24.6 million for the prior-year period, with the increase attributable to the intangibles acquired from the XOMA acquisition. Research and development expense was $19.6 million, compared with $77.7 million for the prior-year period, reflecting several prior-year charges: $44.3 million for the research and development funding arrangement associated with the D-Fi royalty rights acquired in the Castle Creek transaction, $17.8 million for the arrangement associated with the AVIM Therapy royalty rights acquired in the Orchestra BioMed transaction, and $6.4 million related to Ligand’s former Pelthos business. This was partially offset by $12.3 million of research and development funding arrangement expense recognized in the current-year period related to Orchestra BioMed. General and administrative expense was $122.6 million, compared with $67.4 million for the prior-year period. The increase primarily reflects transaction and integration costs and share-based compensation associated with the XOMA acquisition, as well as higher employee-related costs, including increased headcount, from the expansion of Ligand’s portfolio management and origination platform to scale its larger royalty portfolio.

Net non-operating expense was $14.7 million for the nine months ended September 30, 2026, compared with net non-operating income of $76.5 million for the prior-year period. The change was primarily attributable to non-cash mark-to-market losses on equity-method investments and other investments during the nine months ended

September 30, 2026, compared with non-cash gains recognized in the prior-year period, partially offset by higher gains on short-term investments and higher net interest income.

GAAP net income was $6.7 million, or $0.31 per diluted share, for the nine months ended September 30, 2026, compared with $79.7 million, or $3.95 per diluted share, for the prior-year period. Results for the nine months ended September 30, 2026 included a $49.2 million pre-tax, non-cash loss from change in fair value of equity-method investments and other investments.

Adjusted net income was $142.9 million, or $6.67 per diluted share, compared with $122.4 million, or $6.07 per diluted share, for the prior-year period, representing year-over-year increases of 17% and 10%, respectively. The increase was primarily attributable to the 46% increase in royalty revenue, higher net interest income and realized gains on short-term investments, partially offset by higher general and administrative expense. Adjusted net income is a non-GAAP financial measure. See the table below for a reconciliation of GAAP net (loss) income to adjusted net income.

Adjusted Financial Measures

Ligand reports adjusted net income and adjusted earnings per diluted share in addition to, and not as a substitute for, financial measures calculated in accordance with GAAP, and does not consider such measures superior to GAAP results. The Company also reports “core” versions of these measures, which exclude any gains on the sale of the Pelthos business.

Adjusted earnings per diluted share is a key component of the financial metrics utilized by the Company’s board of directors to evaluate management performance and determine certain elements of management compensation. GAAP results include items such as share‑based compensation expense, amortization of acquisition‑related and intangible assets, changes in contingent liabilities, mark‑to‑market adjustments on investments in public companies, transaction‑related costs and related tax effects, which are excluded from adjusted results and are detailed in the reconciliations included at the end of this press release.

This press release includes adjusted total revenues and income, which excludes all $53.1 million of Pelthos-related income recognized in the prior-year period, including the portion attributed to out-license fees. Ligand believes the adjusted total revenues and income is a more meaningful indicator of its business performance than the GAAP total revenues and income.

Liquidity and Capital Resources

As of September 30, 2026, Ligand had cash, cash equivalents, and short-term investments of $447.4 million, compared with $733.5 million at December 31, 2025. The decrease was primarily driven by cash used for the XOMA acquisition, partially offset by the proceeds from the Company’s issuance of its convertible senior notes due 2031. As of September 30, 2026, including its equity investments and availability under its credit facility, Ligand has approximately $750 million of deployable capital available to pursue additional royalty acquisitions and strategic investments.

2026 Financial Guidance

Ligand is raising its 2026 full year adjusted earnings per diluted share guidance and reaffirming its 2026 revenue guidance. Ligand now expects the following:

•Royalty revenue of $225 million to $250 million (unchanged)

•Captisol sales of $35 million to $40 million (unchanged)

•Contract revenue of $10 million to $20 million (unchanged)

•Total revenue of $270 million to $310 million (unchanged)

•Adjusted earnings per diluted share2 of approximately $9.50 to $9.75, raised from approximately $9.00 to $9.50

Third Quarter Corporate Highlights

On July 14, 2026, Ligand completed the acquisition of XOMA Royalty, a biotechnology royalty aggregator. The acquisition strengthens Ligand’s royalty portfolio by adding seven commercial products, including Roche’s VABYSMO® (faricimab-svoa), Servier and Ipsen’s OJEMDA™ (tovorafenib), and Zevra Therapeutics’ MIPLYFFA® (arimoclomol). Additionally, the acquisition adds 14 late-stage development programs, featuring Takeda’s mezagitamab and certain assets from Takeda’s externalized asset portfolio, including osavampator, volixibat, and OHB-607, along with more than 100 additional assets in various stages of development to Ligand’s portfolio. As a result, Ligand’s portfolio has more than doubled in size, now comprising over 200 commercial, clinical, and preclinical stage royalty assets.

On September 22, 2026, Ligand announced the acquisition of a milestone and royalty interest in Santen Pharmaceutical’s Ryjunea from Sydnexis for a $23 million upfront payment. Under the terms of the agreement, Ligand acquired a 100% interest in certain payments and related rights under Sydnexis’s existing license agreement with Santen. The acquired payment rights include a tiered low-double-digit to high-teens royalty on Ryjunea net sales in Europe, the Middle East and Africa, as well as certain milestone payments.

On September 24, 2026, Ligand announced it entered into a financing agreement with AvenCell Therapeutics, Inc., a clinical-stage cell therapy company developing controllable, allogeneic CAR-T therapies for patients with cancer, for up to $47 million. The investment is expected to help advance AvenCell’s pipeline, including AVC-201 for the treatment of relapsed/refractory acute myeloid leukemia (AML) and AVC-203 for the treatment of B-cell malignancies. Under the terms of the agreement, Ligand has committed up to $41 million in exchange for a mid single-digit to low double-digit royalty on worldwide annual net sales of all current and future AvenCell pipeline assets, with the applicable rate determined based on the total amount ultimately funded. The capital will be funded in four tranches, with the first tranche payable at closing, and the remaining three tranches payable upon achievement of certain predetermined clinical milestones and other specified financing conditions. Ligand has also committed up to $6 million in AvenCell’s concomitant Series C financing.

2 A reconciliation of forward-looking non-GAAP adjusted earnings per diluted share to the most directly comparable GAAP measure is not available without unreasonable effort, as certain items cannot be reasonably predicted because of their high variability, complexity and low visibility. Specifically, non-cash adjustments that could be made for changes in contingent liabilities, changes in the market value of its investments in public companies, share-based compensation expense and the effects of any discrete income tax items, directly impact the calculation of our core adjusted earnings per diluted share.

(1) Amounts include a $10.8 million of share-based compensation expense recognized during the three and nine months ended September 30, 2026, related to the cash settlement of XOMA equity awards, which represents the portion attributable to the post-combination service period.

(2) Amounts represent (a) non-cash interest expense in connection with the royalty and milestone payments purchase agreement assumed as part of the Novan acquisition in September 2023; (b) non-cash debt related costs that are calculated in accordance with the authoritative accounting guidance for our convertible debt instruments that may be settled in cash and revolving credit facility; and (c) non-cash interest income from notes receivable.

(3) Amounts represent a portion of the contract payments and royalty receipts that are applied to reduce the carrying balance of our financial royalty assets.

(4) Amounts represent fair value adjustments to contingent liabilities assumed in the XOMA acquisition and those related to the CyDex and Metabasis transactions.

(5) Amounts represent (a) costs of $14.2 million and $19.1 million for the three and nine months ended September 30, 2026, respectively, related to the acquisition of XOMA, consisting primarily of advisory, legal and accounting fees; (b) severance costs and other integration related costs associated with the XOMA acquisition; and (c) costs related to other business development transactions.

(6) Amounts represent gains or losses from changes in the fair value of the Pelthos equity-method investment and Pelthos Series A Preferred Shares.

(7) During the third quarter of 2025, the Company recognized $53.1 million of income related to the divestiture of its Pelthos subsidiary, consisting of $24.5 million associated with the out-license of Zelsuvmi and a $28.6 million gain on the sale of the business. The full $53.1 million was recognized in contract revenue and income. For purposes of adjusted net income, management included the $24.5 million attributable to the out-license of Zelsuvmi and excluded the $28.6 million gain on the sale of the business. Management believes this presentation enhances transparency and comparability by reflecting the license-related component within ongoing operating results while excluding the gain associated with the sale of the business.

(8) Excess tax benefit from share-based compensation is recorded as a discrete item within the provision for income taxes on the consolidated statements of operations as a result of the adoption of an accounting pronouncement (ASU 2016-09) on January 1, 2017. Prior to the adoption, the amount was recognized in additional paid-in capital on the consolidated statement of stockholders’ equity.
