CAUTIONARY NOTE ABOUT FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of the federal securities laws, which statements are subject to substantial risks and uncertainties and are based on estimates and assumptions. All statements, other than statements of historical facts, including statements concerning our plans, objectives, goals, strategies, future events, future revenues or performance, financing needs, plans or intentions relating to products and markets, and business trends and other information referred to in this Quarterly Report on 10-Q, including under the sections entitled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” are forward-looking statements. In some cases, you can identify forward-looking statements by terms such as “may,” “might,” “will,” “objective,” “intend,” “should,” “could,” “can,” “would,” “expect,” “believe,” “design,” “estimate,” “predict,” “potential,” “plan,” “develop,” or the negative of these terms, and similar expressions intended to identify forward-looking statements. Forward-looking statements are not historical facts, and reflect our current views with respect to future events, outcomes or results. Given the significant risks and uncertainties, you should not place undue reliance on these forward-looking statements.

There are a number of risks, uncertainties and other factors that could cause our actual results or outcomes, or the timing of our results or outcomes, to differ materially from the forward-looking statements expressed or implied in this Quarterly Report on Form 10-Q. Such risks, uncertainties and other factors include, among others, the following:

•the timing of the initiation, progress, and expected results of our nonclinical studies, our clinical trials, and our research and development programs;

•our ability to enroll patients in our clinical trials;

•the costs related to our nonclinical studies, our clinical trials, our research and development programs, and the impact of inflationary pressures on such costs;

•our ability to retain the continued service of our key executives and to identify, hire, and retain additional qualified professionals;

•our ability to advance product candidates into, and successfully complete, nonclinical studies and clinical trials;

•the timing or likelihood of regulatory filings and approvals;

•the commercialization of our product candidates, if approved;

•our ability and the potential to successfully manufacture and supply our product candidates for clinical trials and for commercial use, if approved;

•the pricing, coverage, and reimbursement of our product candidates, if approved;

•the implementation of our business model, strategic plans for our business, and product candidates;

•the scope of protection we are able to establish and maintain for intellectual property rights covering our technology;

•our potential need to obtain additional licenses of third-party technology that may not be available to us or are available only on commercially unreasonable terms, and which may cause us to operate our business in a more costly or otherwise adverse manner that was not anticipated;

•our ability to enter into strategic arrangements and/or collaborations and to realize the potential benefits of such arrangements;

•our ability to contract with third-party suppliers and manufacturers and their ability to perform adequately;

•our estimates regarding the market opportunity for our product candidates, if approved;

•our estimates regarding expenses, capital requirements, and needs for additional financing and our ability to obtain additional capital;

•our financial performance;

•developments relating to our competitors and our industry, including competing product candidates and therapies; and

•economic downturns, inflation, fluctuating interest rates, changes in trade policies, including tariffs or other trade restrictions or the threat of such actions, natural disasters, public health crises, such as pandemics, political crises, government shutdowns, geopolitical events, or other macroeconomic conditions.

There may be other risks, uncertainties, and other factors that may cause our actual results or outcomes, or the timing of our results or outcomes, to differ materially from the forward-looking statements expressed or implied in this Quarterly Report on Form 10-Q, including those risks, uncertainties and other factors disclosed in “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this Quarterly Report on Form 10-Q and in the same sections in our Annual Report on Form 10-K for the year ended December 31, 2025, as well as in our other filings with the SEC. You should evaluate all forward-looking statements made in this Quarterly Report on Form 10-Q in the context of these risks, uncertainties and other factors.

We caution you that the risks, uncertainties, and other factors referred to above and elsewhere in this Quarterly Report on Form 10-Q and in our Annual Report on Form 10-K for the year ended December 31, 2025 may not contain all of the risks, uncertainties and other factors that may affect our future results and operations. Moreover, new risks will emerge from time to time. It is not possible for our management to predict all risks. In addition, we cannot assure you that we will realize the results, outcomes, benefits or developments that we expect or anticipate or, even if substantially realized, that they will result in the consequences or affect us or our business in the way we expect.

Any forward-looking statements contained in this Quarterly Report on Form 10-Q speak only as of the date hereof and not of any future date, and we expressly disclaim any intent to update any forward-looking statements, whether as a result of new information, future developments, future events, changes in assumptions or otherwise.
