TABLE OF CONTENTS

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements contained in this Annual Report on Form 10-K other than statements of historical fact, including statements concerning our business strategy and plans, future operating results and financial position, as well as our objectives and expectations for our future operations, are forward-looking statements.

In some cases, you can identify forward-looking statements by such terminology as “believe,” “may,” “will,” “potentially,” “estimate,” “continue,” “anticipate,” “intend,” “could,” “would,” “project,” “plan,” “expect” and similar expressions that convey uncertainty of future events or outcomes, although not all forward-looking statements contain these words. Forward-looking statements include, but are not limited to, statements about:

•the timing and conduct of our clinical trial programs for our lead drug candidates NX-5948, NX-2127 and NX-1607 and other drug candidates, including statements regarding the timing of data and anticipated announcements, the selection of new development candidates and the initiation of clinical trials;

•the timing of, and our ability to obtain, marketing approvals for our lead drug candidates NX-5948, NX-2127 and NX-1607 and other drug candidates;

•our plans to pursue research and development of other drug candidates;

•the timing of investigational new drug application (IND) submissions for our drug candidates;

•the potential advantages of our DEL-AI platform, our drug candidates and degrader antibody conjugates (DACs);

•the extent to which our scientific approach, our DEL-AI platform, protein degradation, antibody-drug conjugation, and DACs may potentially address a broad range of diseases;

•the potential benefits of our arrangements with Gilead Sciences, Inc., Sanofi S.A. and Seagen Inc. (now a part of Pfizer Inc.);

•the timing of and our ability to obtain and maintain regulatory approvals for our drug candidates;

•the potential receipt of revenue from future sales of our drug candidates;

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

•our estimates regarding the potential market opportunity for our drug candidates;

•our sales, marketing and distribution capabilities and strategy;

•our ability to establish and maintain arrangements for the manufacturing of our drug candidates;

•the expected impact of global business, political and macroeconomic conditions, including inflation, interest rate fluctuations and volatile market conditions, uncertainty with respect to the federal budget and debt ceiling and potential government shutdowns related thereto, cybersecurity events, instability in the global banking system, and global events, including regional conflicts around the world, on our business, clinical trials, financial condition, liquidity and results of operations;

•the potential achievement of milestones and receipt of royalty payments under our collaborations;

•our ability to enter into additional collaborations with third parties;

•our intellectual property position;

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

•the impact of government laws and regulations; and

•our competitive position.

We have based these forward-looking statements largely on our current expectations and projections about future events and trends that we believe may affect our business, financial condition, results of operations, prospects and financial needs. These forward-looking statements speak only as of the date of this Annual Report on Form 10‑K and are subject to a number of risks, uncertainties and assumptions described in the section titled “Risk Factors” and elsewhere in this Annual Report on Form 10-K. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. We disclaim any intention or obligation to publicly update or revise any forward-looking statements for any reason or to conform such statements to actual results or revised expectations, except as required by law.

RISK FACTOR SUMMARY

Our business is subject to a number of risks and uncertainties, including those risks discussed at-length below. These risks include, among others, the following:

•We have incurred significant losses since our inception. We expect to incur losses over at least the next several years and may never achieve or maintain profitability.

•We have never generated revenue from product sales and may never be profitable.

•We will need substantial additional funding. If we are unable to raise capital when needed, we may be required to delay, limit, reduce or terminate our research or product development programs or future commercialization efforts.

•Current and future legislation may increase the difficulty and cost for us, and any collaborators, to obtain marketing approval of and commercialize our drug candidates and affect the prices we, or they, may obtain.

•We are early in our development efforts. Our lead drug candidates, NX-5948, NX-2127 and NX-1607, are in the early stages of clinical development. If we are unable to advance our drug candidates through clinical development, develop, obtain regulatory approval for and commercialize our drug candidates or experience significant delays in doing so, our business may be materially harmed.

•Our limited operating history may make it difficult to evaluate the success of our business to date and to assess our future viability.

•If serious adverse events, undesirable side effects or unexpected characteristics are identified during the development of any drug candidates we may develop, we may need to abandon or limit our further clinical development of those drug candidates.

•The results of preclinical studies and early-stage clinical trials may not be predictive of future results. Initial success in clinical trials may not be indicative of results obtained in later-stage trials or when these trials are completed.

•If we decide to seek Orphan Drug Designation or other designations from regulators for any of our current or future drug candidates, we may be unsuccessful or may be unable to maintain the benefits associated with these designations, including the potential for supplemental market exclusivity associated with an Orphan Drug Designation.

•If any of our drug candidates are not considered to be a new active substance or are deemed to fall within the “global marketing authorization” of an existing medicinal product or if pediatric studies are not adequately completed, such drug candidates may fail to obtain regulatory data protection or an extension to existing regulatory data protection.

•We face substantial competition in an environment of rapid technological change, which may result in others discovering, developing or commercializing products before or more successfully than we do.

•We expect to depend on collaborations with third parties for the research, development and commercialization of certain of the drug candidates we may develop. If any such collaborations are not successful, we may not be able to capitalize on the market potential of those drug candidates.

•We rely on third-party contract manufacturing organizations (CMOs) for the manufacture of both drug substance and finished drug product for our drug candidates for preclinical and clinical testing and expect to continue to do so for any future clinical trials and commercialization. This reliance on third parties may increase the risk that we will not have sufficient quantities of our drug candidates or products or such quantities at an acceptable cost or quality, which could delay, prevent or impair our development or commercialization efforts.

•If we are unable to obtain and maintain patent protection for our technology, our current drug candidates and any future drug candidates that we may develop, or if the scope of the patent protection obtained is not sufficiently broad, our competitors and other third parties could develop and commercialize technology and drug candidates similar or identical to ours, and our ability to successfully commercialize our technology and drug candidates may be impaired, and we may not be able to compete effectively in our market.

•We may not identify relevant third-party patents or may incorrectly interpret the relevance, scope or expiration of a third-party patent, and third parties may initiate legal proceedings alleging that we are infringing, misappropriating or otherwise violating their intellectual property rights, the outcome of which would be uncertain and could have a material adverse effect on our business.

•Unfavorable global economic conditions could adversely affect our business, financial condition, stock price and results of operations.

•If we fail to attract and retain management and other key personnel, we may be unable to continue to successfully develop our current and any future drug candidates, commercialize our drug candidates or otherwise implement our business plan.

•Even if we are able to commercialize any drug candidates, the products may become subject to unfavorable pricing regulations, third-party reimbursement practices or healthcare reform initiatives, or fail to secure a positive health technology assessment, which would harm our business.
