Ligand Reports Second Quarter 2019 Financial Results

Ligand Pharmaceuticals Incorporated (NASDAQ: LGND) today reported financial results for the three and six months ended June 30, 2019, and provided an operating forecast and program updates. Ligand management will host a conference call today beginning at 9:00 a.m. Eastern time to discuss this announcement and answer questions.

“During the quarter we reported positive top-line results from our Phase 1 trial with CE-Iohexol. Sage Therapeutics launched ZULRESSO, and in doing so added another key commercial asset to Ligand’s portfolio. We purchased a synthetic royalty from Novan on SB206, and Novan launched a Phase 3 trial with that compound for the treatment of molluscum contagiosum. Finally, our business development team has been very active in licensing, with two new partnerships from our OmniAb technology, two from our VDP technology and five new or advanced Captisol deals. In addition, this month we closed an acquisition of an antigen discovery company,” said John Higgins, Chief Executive Officer of Ligand. “The sources of potential growth within our existing pipeline are rich and diversified, and we anticipate additional positive news flow throughout the remainder of the year. Over the longer term, we expect Ligand’s pipeline to be a significant source of meaningful and diversified cash flow.”

Second Quarter 2019 Financial Results

Total revenues for the second quarter of 2019 were $25.0 million, compared with $90.0 million for the same period in 2018. Royalties were $6.6 million, compared with $31.4 million for the second quarter of 2018 and primarily consisted of royalties from Kyprolis and EVOMELA. Royalties in the second quarter of 2018 include royalties from Promacta, which was sold to Royalty Pharma as of March 6, 2019, for $827 million; Ligand did not receive any Promacta royalties in the second quarter of 2019 and will not receive any Promacta royalties going forward. Material sales were $8.5 million, compared with $7.6 million for the same period in 2018 due to the timing of Captisol purchases for use in clinical trials and commercial products. License fees, milestones and other revenues were $9.8 million, compared with $51.0 million for the same period in 2018, which included a $47 million payment from WuXi Biologics to amend its OmniAb platform license agreement.

Cost of material sales was $2.4 million for the second quarter of 2019, compared with $1.1 million for the same period in 2018, due to the timing and mix of Captisol sales. Amortization of intangibles was $3.5 million, compared with $3.3 million for the same period in 2018. Research and development expense was $12.2 million, compared with $6.1 million for the same period of 2018, due to costs associated with the VDP research team acquired recently and non-cash amortization of the upfront investments in the Palvella and Novan programs. General and administrative expense was $11.0 million, compared with $9.3 million for the same period in 2018.

Net loss for the second quarter of 2019 was $14.4 million, or $0.74 per diluted share, compared with net income of $73.2 million, or $2.99 per diluted share, for the same period in 2018. The second quarter of 2019 net loss was affected by a non-cash change in the value of Ligand’s investment in Viking Therapeutics of $12.4 million. Adjusted net income for the second quarter of 2019 was $13.9 million, or $0.68 per diluted share, compared with $60.6 million, or $2.59 per diluted share, for the same period in 2018.

As of June 30, 2019, Ligand had cash, cash equivalents and short-term investments of $1.3 billion, after having spent approximately $105 million on share repurchase and taxes, principally associated with taxes related to the $827 million sale of Promacta.

Year-to-Date Financial Results

Total revenues for the six months ended June 30, 2019 were $68.5 million, compared with $146.2 million for the same period in 2018.

Royalties for the six months ended June 30, 2019 primarily consisted of royalties from Promacta, Kyprolis and EVOMELA and do not include contribution from Promacta after March 6, 2019, whereas 2018 royalties included a full six months of Promacta royalties. Material sales were $17.5 million, compared with $12.0 million for the same period in 2018, due to the timing of Captisol purchases for use in clinical trials and commercial products. License fees, milestones and other revenues were $24.8 million, compared with $82.0 million for the same period in 2018, which included a $47 million payment from WuXi Biologics to amend its OmniAb platform license agreement as well as a $20 million upfront payment upon the licensing of Ligand’s GRA program.

Cost of material sales was $6.3 million for the six months ended June 30, 2019, compared with $1.9 million for the same period in 2018 due to the timing and mix of Captisol sales. Amortization of intangibles was $7.0 million, compared with $6.6 million for the same period in 2018. Research and development expense was $23.5 million, compared with $13.5 million for the same period of 2018, due to costs associated with recent acquisitions.

Other Licensing and Acquisition Events

• Ligand announced the acquisition of economic rights to SB206 from Novan, Inc. SB206 is a Phase 3 topical antiviral gel for the treatment of skin infections, including molluscum contagiosum.

Metavant may choose to explore certain other indications and/or geographies for RVT-1502 and expects to make a decision later this year.
• Sermonix Pharmaceuticals announced that lasofoxifene has been granted Fast Track designation by the FDA and presented a poster on the preclinical performance of its lead investigational drug, lasofoxifene, at the 2019 American Society of Clinical Oncology (ASCO) Annual Meeting.
• Daiichi Sankyo announced the launch in Japan of MINNEBRO (esaxerenone) tablets.

• Nucorion Pharmaceuticals announced the closing of a $5 million Series B Preferred Stock financing to support the Phase 1 clinical development in the US for its lead program, NCO-1010 for the potential treatment of hepatitis B, which utilizes Ligand’s LTP Platform technology. Guangdong Ji-Bao Pharmaceutical Company of Guangzhou, China invested $4 million and Ligand invested $1 million in the round.

Internal R&D

• Ligand announced positive top-line results from a Phase 1 clinical trial of its internal Captisol-enabled (CE) Iohexol program. The trial achieved the primary endpoint by demonstrating pharmacokinetic bioequivalence of CE-Iohexol injection and a reference Iohexol injection (OMNIPAQUE) after intravenous (IV) administration in healthy adults. CE-Iohexol injection was safe and well tolerated, and adverse events were in line with the known safety profile of OMNIPAQUE.

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 stock-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, unissued shares relating to its Senior Convertible Notes, gain on the sale of Promacta and others that are listed in the itemized reconciliations between GAAP and adjusted financial measures included at the end of this press release. However, other than with respect to total revenues, the Company only provides financial guidance on an adjusted basis and 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, stock-based compensation expense and 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.
