Limitation of Incorporation by Reference

In accordance with General Instruction B.2. of Form 8-K, this information, including the Exhibit, is furnished pursuant to Item 7.01 and shall not be deemed to be “filed” for the purpose of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section.

Cautionary Statements

Certain statements in the attached exhibit are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, including statements regarding: future monetization opportunities, active transactions with significant financial implications, collaborations poised for significant financial contribution, our library of value-generating assets, future potential for milestone and royalty payments, the potential of our unique antibody discovery engine, the ability of our partners and their licensees to successfully develop their pipeline programs, the productivity of acquired assets that may not fulfill our revenue forecasts, upcoming internal milestones and value catalysts, our future cash needs, our strategy for value creation, and other statements that relate to future periods. These statements are based on assumptions that may not prove accurate, and actual results could differ materially from those anticipated due to certain risks inherent in the biotechnology industry and for companies engaged in the development of new products in a regulated market. Potential risks to XOMA meeting these expectations are described in more detail in XOMA’s most recent filing on Form 10-K for the year ended December 31, 2018 and in other more recent SEC filings. Consider such risks carefully when considering XOMA’s prospects. Any forward looking statements represent XOMA’s views only as of the date of this presentation and should not be relied upon as representing its views as of any subsequent date. XOMA disclaims any obligation to update any forward-looking statement, except as required by law.
