TABLE OF CONTENTS

FORWARD-LOOKING STATEMENTS

This report includes 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. Forward-looking statements include statements that may relate to our plans, objectives, goals, strategies, future events, future revenues or performance, capital expenditures, financing needs and other information that is not historical information. Many of these statements appear, in particular, under the headings "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in this Annual Report on Form 10-K. Forward-looking statements can often be identified by the use of terminology such as "subject to", "believe", "anticipate", "plan", "expect", "intend", "estimate", "project", "may", "will", "should", "would", "could", "can", the negatives thereof, variations thereon and similar expressions, or by discussions of strategy.

All forward-looking statements, including, without limitation, our examination of historical operating trends, are based upon our current expectations and various assumptions. We believe there is a reasonable basis for our expectations and beliefs, but they are inherently uncertain. We may not realize our expectations, and our beliefs may not prove correct. Actual results could differ materially from those described or implied by such forward-looking statements. The following uncertainties and factors, among others (including those set forth under "Risk Factors"), could affect future performance and cause actual results to differ materially from those matters expressed in or implied by forward-looking statements:

•our plans to develop and commercialize our product candidates;

•the outcomes of our ongoing and planned clinical trials and the timing of those outcomes, including when clinical trials will be initiated or completed, enrollment of trials, and when data will be reported or regulatory filings will be made;

•our estimates regarding expenses, future revenue, capital requirements and needs for additional financing;

•our ability to raise additional capital through the capital markets or through one or more corporate partnerships, equity offerings, debt financings, collaborations, licensing arrangements or asset sales;

•our expectations regarding product candidates currently being developed by our collaborators;

•the anticipated receipt of sales milestone payments in connection with the sale of MARGENZA to TerSera Therapeutics, LLC, or TerSera;

•the compromise of our or our third parties’ information technology systems and resultant costs, disruptions in our operations or related impact on our reputation;

•our ability to enter into new collaborations or to identify additional products or product candidates with significant commercial potential that are consistent with our commercial objectives;

•the potential benefits and future operation of our existing collaborations;

•our ability to recover the investment in our manufacturing capabilities;

•the rate and degree of market acceptance and clinical utility of our products;

•our commercialization, marketing and manufacturing capabilities and strategy;

•significant competition in our industry;

•costs of litigation and the failure to successfully defend lawsuits and other claims against us and our expectations regarding the outcome of any regulatory or legal proceedings;

•economic, political and other risks associated with our international operations;

•our ability to receive research funding and achieve anticipated milestones under our collaborations;

•our ability to protect and enforce patents and other intellectual property;

•costs of compliance and our failure to comply with new and existing governmental regulations including, but not limited to, tax regulations;

•loss or retirement of key members of management;

•failure to successfully execute our growth strategy, including any delays in our planned future growth;

•our failure to maintain effective internal controls; and

•the impact of legislative and regulatory developments, public health crises, geopolitical tensions or other macroeconomic factors on our business, operations, clinical programs, manufacturing, financial results and other aspects of our business.

Consequently, forward-looking statements speak only as of the date that they are made and should be regarded solely as our current plans, estimates and beliefs. You should not place undue reliance on forward-looking statements. We cannot guarantee future results, events, levels of activity, performance or achievements. Except as required by law, we do not undertake and specifically decline any obligation to update, republish or revise forward-looking statements to reflect future events or circumstances or to reflect the occurrences of unanticipated events.
