XOMA Reports Third Quarter 2018 Financial Results

EMERYVILLE, Calif., November 7, 2018 (GLOBE NEWSWIRE)– XOMA Corporation (Nasdaq: XOMA), a biotechnology royalty aggregator, today announced its third quarter 2018 financial results.

“The third quarter of 2018 was exciting for XOMA, as we completed our first royalty and milestone acquisition under our royalty aggregator business model. The transaction increased our portfolio of fully funded assets to 45 and met each characteristic we established for the assets we intend to acquire: (a) therapeutic atpre-commercial stage, (b) long duration of potential royalty term, (c) being advanced by a strong partner. We continue to assess royalty monetization opportunities that could add fully funded assets to our portfolio,” said Jim Neal, Chief Executive Officer at XOMA. “We have a large and diverse set of potential milestone and royalty bearing assets in our portfolio, and this means our success is not dependent upon any single asset. We believe our risk is mitigated further with each asset we add to our portfolio.”

Financial Results

XOMA recorded total revenues of $0.9 million for the third quarter of 2018 compared with $36.2 million in the third quarter of 2017. The decrease was due to license and collaborative fee revenue recognized in connection with the license agreements XOMA executed with Novartis in August 2017.

Research and development (R&D) expenses were $0.6 million for the third quarter of 2018, compared to $0.3 million for the third quarter of 2017. The increase in R&D expenses during the third quarter of 2018 was due to aone-time adjustment for external manufacturing costs in the third quarter of 2017 of $0.7 million to reverse the cost of a batch of drug material that did not meet quality standards. This difference was partially offset by decreases in outside consulting fees and the allocation of facilities charges in response to the change in our business model.

General and administrative (G&A) expenses were $4.7 million for the third quarter of 2018, compared to $7.3 million for the third quarter of 2017. The decrease of $2.6 million for the three months ended September 30, 2018, as compared to the same period of 2017, was due primarily to decreases of $1.1 million in consulting services, $1.2 million in stock-based compensation, and $0.1 million in legal and accounting fees.

In the third quarter of 2018, XOMA recorded a lease-related restructuring charge of $0.9 million as the Company completely vacated the facilities in Berkeley, California previously used for lab space and headquarters.

Total other income, net was $0.9 million for the third quarter of 2018, compared to other expense of $0.3 million for the third quarter of 2017. During the third quarter of 2018, XOMA recorded $0.5 million in income from Ology Bioservices related to the disposition of its biodefense business in March 2016 and $0.5 million in sublease income. Separately, the Company received long-term marketable securities that consisted of an investment in Rezolute Inc.’s common stock under the terms of a licensing agreement. As of September 30, 2018, the fair value of the long-term marketable securities had decreased resulting in the recognition of a $0.2 million loss.

Net loss for the third quarter of 2018 was $4.6 million, compared to net income of $26.3 million for the third quarter of 2017.

On September 30, 2018, XOMA had cash and cash equivalents of $28.4 million. The Company ended December 31, 2017, with cash and cash equivalents of $43.5 million. During the third quarter of 2018, XOMA acquired a royalty interest position on seven assets being developed by Merck and Incyte. The $15 million Royalty Purchase Agreement with Agenus, Inc., was funded with $7.5 million from XOMA’s cash and cash equivalents and $7.5 million through a drawdown of XOMA’s line of credit from Silicon Valley Bank. The Company’s current cash and cash equivalents are expected to be sufficient to fund its operations into 2021.
