**Ligand Reports Fourth Quarter and Full Year 2022 Financial Results**

**2023 Financial Guidance Raised**

**Conference Call Begins at 4:30 p.m. Eastern Time Today**

**SAN DIEGO, Calif. (February 22, 2023) – Ligand Pharmaceuticals Incorporated (NASDAQ: LGND)** today reported financial results for the three and 12 months ended December 31, 2022, and provided an operating forecast and business updates. These financial results are presented on a continued operations basis as OmniAb was spun out on November 1, 2022 and is reported as discontinued operations. Ligand management will host a conference call today beginning at 4:30 p.m. Eastern time to discuss this announcement and answer questions.

"2022 was a transformative year for Ligand, both operationally and financially. Following Ligand's spin out of OmniAb, we believe we are well positioned to achieve significant revenue growth coupled with a lean cost structure," said Todd Davis, CEO of Ligand. "As we look to 2023 and beyond, we anticipate important clinical and regulatory events from our partners, along with the continued expansion of our portfolio through a focus on life sciences royalty opportunities."

**Fourth Quarter 2022 Financial Results**

Total revenues for the fourth quarter of 2022 were $50.4 million, compared with $56.4 million for the same period in 2021. Royalties for the fourth quarter of 2022 were $22.0 million, compared with $17.6 million for the same period in 2021, with the increase primarily attributable to the growth in sales of drugs using the Pelican platform. Core Captisol sales were $3.3 million for the fourth quarter of 2022, compared with $7.1 million for the same period in 2021. The difference in sales was due to the timing of customer orders. Captisol sales related to COVID-19 were $23.5 million for the fourth quarter of 2022, compared with $28.3 million for the same period in 2021. Contract revenue was $1.5 million for the fourth quarter of 2022, compared with $3.5 million for the same period in 2021. The difference was due to the timing of partner milestone events.

Cost of Captisol was $21.6 million for the fourth quarter of 2022, compared with $12.0 million for the same period in 2021, with the increase primarily due to $9.8 million in accelerated depreciation on Captisol manufacturing equipment during the fourth quarter of 2022. Amortization of intangibles was $8.5 million, compared with $8.6 million for the same period in 2021. Research and development expense was $9.2 million, compared with $8.1 million for the same period in 2021, with the increase attributed to stock based compensation and an increase in facility related expenses in the fourth quarter of 2022. General and administrative expense was $31.1 million, compared with $12.6 million for the same period in 2021, with the increase primarily attributable to a one-time stock compensation expense associated with the retirement of our former CEO in the fourth quarter of 2022 and legal expenses incurred in connection with the OmniAb spin out.

Net loss from continuing operations for the fourth quarter of 2022 was $14.5 million, or $0.86 per share, compared with $3.2 million, or $0.19 per share, for the same period in 2021. In addition to the aforementioned Captisol equipment accelerated depreciation and stock compensation expense, net loss for the fourth quarter of 2022 was also impacted by a $24.8 million deferred tax asset valuation allowance, offset by a non-cash gain of $44.2 million from the value of Ligand's short-term investments. Net loss for the fourth quarter of 2021 was impacted by a non-cash loss of $13.4 million from the value of Ligand's short-term investments. Adjusted net income from continuing operations for the fourth quarter of 2022 was $23.5 million, or $1.36 per diluted share, compared with $25.5 million, or $1.47 per diluted share, for the same period in 2021. Excluding the impact of gross profit, net of tax, for Captisol sales related to COVID-19, adjusted net income for the fourth quarter of 2022 was $13.0 million, or $0.75

------

per diluted share, compared with $10.7 million, or $0.62 per diluted share, for the same period in 2021. See the table below for a reconciliation of net income (loss) from continuing operations to adjusted net income from continuing operations.

As of December 31, 2022, Ligand had cash, cash equivalents and short-term investments of $211.9 million.

**Full Year 2022 Financial Results**

Total revenues for 2022 were $196.2 million, compared with $241.5 million for 2021. Royalties for 2022 were $72.5 million, compared with $48.9 million for 2021, with the increase primarily attributable to the growth in sales of drugs using the Pelican platform. Core Captisol sales were $16.4 million for 2022, compared with $23.4 million for 2021. The difference in sales was due to the timing of customer orders. Captisol sales related to COVID-19 were $88.1 million for 2022, compared with $140.8 million for 2021. The lower sales are due to reduced demand for the pandemic-related treatment. Contract revenue for 2022 was $19.2 million, compared with $28.4 million for 2021, with the change due to the timing of partner milestone events.

Cost of Captisol was $52.8 million for 2022, compared with $62.2 million for 2021, with the decrease due primarily to lower sales of Captisol, partially offset by $9.8 million in accelerated depreciation on Captisol manufacturing equipment during the year. Amortization of intangibles was $34.2 million for both 2022 and 2021. Research and development expense was $36.1 million for 2022, compared with $32.1 million for 2021, with the increase primarily attributed to higher employee-related expenses and increased facility related expenses. General and administrative expense was $70.1 million for 2022, compared with $46.8 million for 2021, with the increases primarily attributable to stock-compensation expenses, headcount-related expenses and legal expenses.

There was no other operating income for 2022. Other operating income was $37.6 million for 2021, which represented a non-cash valuation adjustment related to eliminating the remaining Pfenex CVR liability.

Net loss from continuing operations for 2022 was $5.2 million, or $0.31 per share, compared with net income from continuing operations of $76.4 million, or $4.43 per diluted share, for 2021. In addition to the aforementioned Captisol equipment accelerated depreciation and increased stock compensation expenses, net loss from continuing operations for 2022 was also impacted by a $24.8 million deferred tax asset valuation allowance, which was partially offset by a $28.8 million net non-cash gain from the value of Ligand's short-term investments. Net income from continuing operations for 2021 included a net non-cash loss from the value of Ligand's short-term investments of $10.6 million. Adjusted net income from continuing operations for 2022 was $82.2 million or $4.79 per diluted share, compared with $108.0 million, or $6.27 per diluted share, for 2021. Excluding the impact of gross profit, net of tax, for Captisol sales related to COVID-19, adjusted net income from continuing operations for 2022 was $41.9 million, or $2.44 per diluted share, compared with $40.5 million, or $2.35 per diluted share, for 2021. See the table below for a reconciliation of net income (loss) from continuing operations to adjusted net income from continuing operations.

**2023 Financial Guidance** 

Ligand is increasing 2023 financial guidance introduced at its Investor and Analyst Day held on December 13, 2022. We now expect 2023 royalties of $74 million to $78 million (previously $72 million to $76 million), sales of Captisol of $21 million (unchanged) and contract revenue of $25 million (unchanged). These revenue components result in total revenue of $120 million to $124 million (previously $118 million to $122 million). Ligand now expects 2023 cash operating expenses of $43 million (previously $46 million), which combined with the increased revenue outlook results in adjusted diluted EPS of $3.30 to $3.45 (previously $3.10 to $3.30). Due to the unpredictable nature of the pandemic and related Captisol sales, Ligand excludes Captisol for remdesivir from guidance and will update investors as orders are received and shipped each quarter.

**Fourth Quarter 2022 and Recent Business Highlights** 

Travere Therapeutics received FDA accelerated approval for FILSPARI (sparsentan) for the treatment of IgA nephropathy (IgAN). FILSPARI is the first and only dual endothelin angiotensin receptor antagonist in development

------

for rare kidney diseases and is the first non-immunosuppressive treatment indicated for IgAN. Travere anticipates a review decision by the EMA on the potential approval for sparsentan for the treatment of IgAN in Europe in the second half of 2023. Additionally, Travere announced that they expect to report top line results from the two-year confirmatory endpoints in the ongoing Phase 3 DUPLEX Study of sparsentan in focal segmental glomerulosclerosis (FSGS) in the second quarter of 2023, with anticipated submission for full approval in the second half of 2023 in both the U.S. and Europe. Travere reported that it ended 2022 with approximately $450 million in cash, cash equivalents and marketable securities, which would be available to support the commercial launch of sparsentan.

Novan announced it has submitted an NDA to the FDA seeking marketing approval for berdazimer gel, 10.3% (SB206) for the topical treatment of molluscum contagiosum (MC). MC is an infection that causes skin lesions and affects approximately six million people in the U.S. annually. Novan anticipates a potential first quarter 2024 approval assuming the filing is accepted by the FDA and standard review timelines.

Verona Pharma announced positive results of its Phase 3 ENHANCE-1 trial evaluating nebulized ensifentrine for the maintenance treatment of COPD. The ENHANCE-1 trial met its primary and key secondary endpoints demonstrating significant improvements in lung function, symptoms and quality of life measures. In addition, ensifentrine substantially reduced the rate and risk of COPD exacerbations. Ensifentrine was well tolerated over 24 and 48 weeks. In 2022 Verona announced that the Phase 3 ENHANCE-2 trial successfully met its primary endpoint and secondary endpoints evaluating lung function and symptoms, and also significantly reduced the rate and risk of COPD exacerbations. Verona plans to file an NDA for inhaled ensifentrine for the maintenance treatment of COPD with the FDA in the first half of 2023.

Viking Therapeutics announced the completion of patient enrollment in its Phase 2b clinical trial of VK2809, a novel liver-selective thyroid hormone receptor beta agonist, in patients with biopsy-confirmed non-alcoholic steatohepatitis (NASH). Viking expects to report data for the study's primary endpoint in the first half of 2023.

Palvella Therapeutics announced its initial closing of up to $37.7 million in financing with proceeds to be used to advance the development of QTORIN rapamycin for the treatment of pachyonychia congenita, microcystic lymphatic malformations (MLM), and for the prevention of basal cell carcinomas in Gorlin syndrome. Palvella expects top-line data in mid-2023 from the Phase 3 pivotal study evaluating QTORIN rapamycin in pachyonychia congenita. Palvella is currently enrolling patients in a multicenter Phase 2b clinical study in the U.S. and Europe for the prevention of basal cell carcinomas in patients with Gorlin syndrome, with data expected in the first half of 2023. Additionally, Palvella expects to report data in the first quarter of 2023 from a multicenter Phase 2 study in the U.S. investigating QTORIN rapamycin for the treatment of MLM.

In 2022, Jazz Pharmaceuticals announced FDA approval of Monday/Wednesday/Friday intramuscular dosing of Rylaze (asparaginase erwinia chrysanthemi (recombinant)-rywn) and submission of a supplemental BLA under the Real-time Oncology Review Program seeking approval for IV administration. Jazz also completed the Marketing Authorization Application submission to the EMA for both IV and IM administration, with a potential approval in 2023. Jazz is also advancing the program for potential submission, approval and launch in Japan.

Xi'an Xintong Pharmaceuticals announced pradefovir reached the primary and secondary endpoints in its Phase 3 clinical trial in China for the treatment of chronic hepatitis B. The 48-week statistical analysis showed that pradefovir was comparable to the first-line drug, tenofovir disoproxil fumarate, with a better safety profile. Xi'an Xintong has submitted a pre-NDA conference communication application with China's National Medical Products Administration (NMPA) and expects to submit an NDA in the first quarter of 2023.

China Resources Double-Crane Pharmaceuticals announced the IND for CX2101A, a small molecule, RNA-dependent RNA polymerase inhibitor of SARS-CoV-2 that utilizes Ligand's proprietary BEPro prodrug technology, was approved by the NMPA for use in clinical trials for the treatment of novel coronavirus pneumonia in China.

Aldeyra announced the submission of an NDA to the FDA for topical ocular reproxalap for the treatment of signs and symptoms of dry eye disease. Reproxalap is a small-molecule modulator of RASP (reactive aldehyde species), which are elevated in ocular and systemic inflammatory disease.

------

Arcellx initiated a Phase 1 study of ARCL-002 in acute myeloid leukemia and myelodysplastic syndromes. ARCL-002 utilizes the Pelican Expression Technology.

**Adjusted Financial Measures**

Ligand reports adjusted net income and adjusted net income per diluted share in addition to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. The Company's financial measures under GAAP include share-based compensation expense, amortization of debt-related costs, amortization related to acquisitions and intangible assets, changes in contingent liabilities, mark-to-market adjustments for amounts relating to its equity investments in public companies, excess tax benefit from share-based compensation, transaction costs, income tax affect of adjusted reconciling items and others that are listed in the itemized reconciliations between GAAP and adjusted financial measures included at the end of this press release. However, the Company does not provide reconciliations of such forward-looking adjusted measures to GAAP due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliation, including 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. Management has excluded the effects of these items in its adjusted measures to assist investors in analyzing and assessing the Company's past and future core operating performance. Additionally, adjusted earnings per diluted share is a key component of the financial metrics utilized by the Company's board of directors to measure, in part, management's performance and determine significant elements of management's compensation.

**Conference Call**

Ligand management will host a conference call today beginning at 4:30 p.m. Eastern time (1:30 p.m. Pacific time) to discuss this announcement and answer questions. To participate via telephone, please dial (888) 350-3452 using the conference ID 6501694. To participate via live or replay webcast, a link is available at www.ligand.com.

**About Captisol**<sup>®</sup>

Captisol is a patent-protected, chemically modified cyclodextrin with a structure designed to optimize the solubility and stability of drugs. Captisol was invented and initially developed by scientists in the laboratories of Dr. Valentino Stella, University Distinguished Professor at the University of Kansas' Higuchi Biosciences Center for specific use in drug development and formulation. This unique technology has enabled several FDA-approved products, including Gilead Sciences' VEKLURY<sup>®</sup>, Amgen's KYPROLIS<sup>®</sup>, Baxter International's NEXTERONE<sup>®</sup>, Acrotech Biopharma L.L.C.'s and CASI Pharmaceuticals' EVOMELA<sup>®</sup>, Melinta Therapeutics' BAXDELA™ and Sage Therapeutics' ZULRESSO™. There are many Captisol-enabled products currently in various stages of development. Ligand maintains a broad global patent portfolio for Captisol with approximately 390 issued patents worldwide relating to the technology (including over 40 in the U.S.) and with the latest expiration date in 2033. Other patent applications covering methods of making Captisol, if issued, extend to 2040.

**About the Pelican Expression Technology™ Platform** 

Pelican is a robust, validated, cost-effective and scalable platform for recombinant protein production that is especially well-suited for complex, large-scale protein production where traditional systems are not.

(1) Amounts represent non-cash debt related costs that are calculated in accordance with the authoritative accounting guidance for convertible debt instruments that may be settled in cash.

(2) Amounts represent the amortization of commercial license and other economic rights to revenue and research and development expenses.

(3) Amounts represent changes in fair value of contingent consideration related to Pfenex, CyDex and Metabasis transactions.

(4) Amounts represent severance costs, legal fees, and certain contract termination costs in connection with the acquisitions.

(5) Amounts primarily relate to restructuring costs, loss on debt extinguishment and adjustments associated with our equity investment in Nucorion.

(6) Amounts represent discrete tax expense related to the valuation allowance established during the fourth quarter of 2022 against deferred tax asset for California research and development credits and net operating losses.

(7) Excess tax benefits from share-based compensation are 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.

(8) Captisol - COVID gross profit, net of tax, represents gross profit, net of tax, for Captisol supplied for use in formulation with remdesivir, an antiviral treatment for COVID-19. Prior period adjusted net income and adjusted net income per diluted share amount have been adjusted to exclude the impact of COVID-related Captisol gross profit, net of tax, to conform to the current period presentation. Certain commission cost included in the general and administrative expenses that were related to the Gilead Consortium sales were included in the calculation for the twelve months ended December 31, 2021.

(9) Excluding the impact from the adoption of accounting pronouncement (ASU 2020-06) on January 1, 2022 as the Company intends to settle the principal balance in cash. Under the new standard, the Company is required to reflect the dilutive effect of the 2023 Notes by application of the if-converted method, which resulted an additional 452,905 and 1,847,893 potentially dilutive shares for the three and twelve months ended December 31, 2022, respectively.
