Forward Looking Statement This presentation includes forward-looking statements within the meaning of the Safe Harbor provisions of the Private Securities Litigation Reform Act of 1995. Such statements are subject to a number of risks and uncertainties, the outcome of which could materially and/or adversely affect actual future results and the trading price of CTI BioPharma's securities. Such statements include, but are not limited to, expectations with respect to the timing and planned enrollment of and interim analysis for PAC203 and submission of responses to Day 120 list of questions, and our ability to interpret clinical trial data and results for PERSIST-2 despite not satisfying the pre-specified minimum evaluable patient goal, expectations with respect to the potential therapeutic utility of pacritinib, statements regarding CTI BioPharma’s expectations with respect to the potential of pacritinib to achieve treatment goals, the development of CTI BioPharma and its product and product candidate portfolio, including the advancement of pacritinib and other pipeline programs, CTI BioPharma’s ability to achieve its goals in 2018 and beyond, including achieving cost efficiency and year-on-year cost reduction goals, CTI BioPharma’s intent to continue efforts to commercialize PIXUVRI in Europe in partnership with Servier and expand the market potential for PIXUVRI, whether positive outcomes to PIX306 could lead to label expansion, and timing of PIX306 top-line results, CTI BioPharma’s plans to continue advancing the development of its pipeline candidates through strategic product collaborations or cooperative group and investigator-sponsored trials, as well as the identification and acquisition of additional pipeline opportunities. In particular, this presentation addresses top-line results regarding data from CTI BioPharma’s Phase 3 trial of pacritinib for the treatment of patients with myelofibrosis whose platelet counts are less than or equal to 100,000 per microliter. Meaningful interpretation of PERSIST-2 may not be possible because the pre-specified minimum evaluable patient goal was not met. Risks that contribute to the uncertain nature of the forward-looking statements include, among others, risks associated with the biopharmaceutical industry in general and with CTI BioPharma and its product and product candidate portfolio in particular including, among others, risks associated with the following: that CTI BioPharma cannot predict or guarantee the outcome of preclinical and clinical studies, the potential failure of pacritinib to prove safe and effective as determined by the FDA and/or the European Medicines Agency, changes to study protocol or design or sample size to address any patient safety, efficacy or other issues raised by the FDA or otherwise, that top-line results observed to date may differ from future results or that different conclusions or considerations may qualify such results once existing data has been more fully evaluated, that CTI BioPharma may not obtain favorable determinations by other regulatory, patent and administrative governmental authorities, that CTI BioPharma may experience delays in the commencement of preclinical and clinical studies, that the costs of developing pacritinib and CTI BioPharma’s other product candidates may rise; other risks, including, without limitation, competitive factors, technological developments, that CTI BioPharma may not be able to sustain its current cost controls or further reduce its operating expenses, that CTI BioPharma may not achieve previously announced goals, contractual milestones and objectives as or when projected, that CTI BioPharma’s average net operating burn rate may increase, that CTI BioPharma will continue to need to raise capital to fund its operating expenses, but may not be able to raise sufficient amounts to fund its continued operation as well as other risks listed or described from time to time in CTI BioPharma’s most recent filings with the Securities Exchange Commission on Forms 10-K, 10-Q and 8-K. Except as required by law, CTI BioPharma does not intend to update any of the statements in this presentation upon further developments. 2
