Ligand Reports Second Quarter 2022 Financial Results

Ligand Pharmaceuticals Incorporated (NASDAQ: LGND) today reported financial results for the three and six months ended June 30, 2022 and provided an operating forecast and program updates. Ligand management will host a conference call today beginning at 4:30 p.m. Eastern time to discuss this announcement and answer questions.

"2022 continues to be an outstanding year for Ligand, in particular as royalties from our Pelican Expression Technology platform grow into meaningful revenue contributors," said John Higgins, CEO of Ligand. "The business is enjoying good momentum with numerous positive late-stage developments announced by our partners this past quarter. Financially, the business is doing very well, and we are solidly positioned to spin-off the expanding OmniAb business through a distribution to shareholders and merger with the Avista SPAC expected to close in the fourth quarter of this year."

Second Quarter 2022 Financial Results

Revenue for the second quarter of 2022 was $57.4 million, compared with $84.7 million for the same period in 2021. Royalty revenue increased 108% to $18.0 million due primarily to Kyprolis and sales of products using the Pelican platform. Core Captisol sales for the second quarter of 2022 were $3.3 million, compared with $9.7 million for the same period in 2021. The difference in sales is due to timing of customer orders. Captisol sales related to COVID-19 were $26.2 million for the second quarter of 2022, compared with $52.8 million for the same period in 2021. The difference in sales is due to reduced demand for the pandemic-related treatment. Contract revenue was $9.9 million, lower than the same period last year which included two significant milestones tied to the Pelican platform. Revenue attributable to the OmniAb business for the second quarter of 2022 was $7.3 million, compared with $5.8 million for the prior year period.

Cost of Captisol was $12.4 million for the second quarter of 2022, compared with $30.6 million for the same period in 2021, with the decrease primarily due to lower total sales of Captisol. Amortization of intangibles was $11.8 million for the second quarter of both 2022 and 2021. Research and development expense was $19.1 million for the second quarter of 2022, compared with $16.0 million for the same period in 2021, with the increase primarily due to continued investment in the OmniAb business including facilities and headcount related expenditures associated with the expected spin-off later this year. General and administrative expense was $14.6 million for the second quarter of 2022, compared with $14.7 million for the same period in 2021.

There was no other operating income for the second quarter of 2022, compared with $34.1 million for the second quarter of 2021, which represented a non-cash valuation adjustment to reduce the Pfenex CVR liability due to an expected lower probability of achieving the required milestone under the Pfenex CVR Agreement.

Net loss for the second quarter of 2022 was $(0.9) million, or $(0.05) per share, compared with net income of $30.7 million, or $1.79 per diluted share, for the same period in 2021. Net loss for the second quarter of 2022 included a $(1.9) million net non-cash loss from the value of Ligand's short-term investments, and net income for the second quarter of 2021 included a $(8.3) million net non-cash loss from the value of Ligand's short-term investments. Adjusted net income for the second quarter of 2022 was $17.6 million, or $1.03 per diluted share, compared with $28.0 million, or $1.63 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 second quarter of 2022 was $5.7 million, or $0.34 per diluted share, compared with $13.0 million, or $0.76 per diluted share, for the same period in 2021. Please see the table below for a reconciliation of net income/(loss) to adjusted net income.

Ligand repurchased $62.0 million in principal amount of its 2023 Notes for $60.0 million in cash during the second quarter of 2022. As of June 30, 2022, Ligand had cash, cash equivalents and short-term investments of $147.9 million.

General and administrative expense was $32.8 million for the six months ended June 30, 2022, compared with $27.0 million expense for the same period in 2021, with the increase primarily due to $5.0 million in transaction costs incurred during the six months ended June 30, 2022 in connection with the planned spin-off of OmniAb.

There was no other operating income for the six months ended June 30, 2022, compared with $33.8 million for the six months ended June 30, 2021, which represented a non-cash valuation adjustment to reduce the Pfenex CVR liability due to an expected lower probability of achieving the required milestone under the Pfenex CVR Agreement.

2022 Financial Guidance

Ligand is raising 2022 revenue guidance for the combined business and is reaffirming revenue estimated to be attributable to the OmniAb business anticipating the spin-off occurs later this year. Ligand expects 2022 royalties of $62 million to $66 million, Captisol sales of $55 million to $60 million and contract revenue of $52 million to $62 million. These revenue components result in total revenue of $169 million to $188 million for the combined business. Ligand expects that $35 million to $45 million of revenue will be attributable to OmniAb, principally in the contract revenue line.

Of the $55 million to $60 million of expected Captisol sales, Ligand expects approximately $17 million to $19 million to be attributable to core Captisol sales, and the balance to be attributable to treatments for COVID-19. Excluding OmniAb revenue and COVID-related Captisol sales, Ligand expects revenue to be $97 million to $104 million and adjusted earnings per diluted share to be $1.80 to $2.05. Ligand expects the contribution from COVID-related Captisol and the OmniAb business to be between $0.60 and $0.95 per diluted share, resulting in a combined company adjusted earnings per diluted share of $2.40 to $3.00.

Update on the OmniAb Separation Process

On March 23, 2022, Ligand announced the signing of a definitive merger agreement with Avista Public Acquisition Corp. II (APAC) (NASDAQ: AHPA), a publicly traded special purpose acquisition company (SPAC), providing for the spin-off and merger of OmniAb. The combination of OmniAb and APAC is structured to provide a minimum of $130 million in gross cash to the combined company at the time of closing, and up to $266 million in the event of no redemptions by APAC shareholders.

OmniAb will have an initial pre-money equity valuation of $850 million. Ligand intends to distribute 100% of its ownership in OmniAb to Ligand shareholders immediately prior to the business combination with APAC. The transaction is expected to be tax-free to Ligand and its shareholders for U.S. federal income tax purposes. The transaction is expected to close in the fourth quarter of 2022.

Adjusted Financial Measures

The Company 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, non-cash interest expense, 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, gross profit for Captisol sales related to COVID-19, net of tax, transaction costs 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.

Important Information and Where to Find It

In April 2022, in connection with the Business Combination and the Distribution, OmniAb filed with the SEC a registration statement on Form 10 (the "Form 10") registering shares of OmniAb Common Stock and APAC filed with the SEC a registration statement on Form S-4 (the "Form S-4") registering shares of APAC Common Stock, warrants and certain equity awards. The Form S-4 filed by APAC includes a proxy statement/prospectus in connection with the APAC shareholder vote required in connection with the Business Combination. The Form 10 filed by OmniAb included portions of the Form S-4 filed by APAC, which will serve as an information statement/prospectus in connection with the spin-off of OmniAb. In June 2022, OmniAb filed with the SEC a request to withdraw the Form 10 because APAC was in the process of responding to comments made by the staff of the Division of Corporation Finance (the "Staff") with respect to the Form S-4. In the absence of this withdrawal request, pursuant to Section 12(g)(1) of the Securities Exchange Act of 1934, as amended, the Form 10 would have automatically become effective on June 27, 2022. Subsequently, the Staff issued additional comments on APAC's Form S-4.
