### RISK FACTORS
An investment in our securities involves a high degree of risk. The prospectus supplement applicable to each offering of our securities will contain a discussion of the risks applicable to an investment in our securities. Before deciding whether to invest in our securities, you should carefully consider the specific factors discussed under the heading “Risk Factors” in the applicable prospectus supplement, together with all of the other information contained or incorporated by reference in the prospectus supplement or appearing or incorporated by reference in this prospectus. You should also consider the risks, uncertainties and assumptions discussed under Item 1A, “Risk Factors,” in our Annual Report on Form 10-K, for the fiscal year ended December 31, 2023, filed with the SEC on February 23, 2023, and our Form 10-Qs, as amended, for the fiscal periods ended March 31, 2024, June 30, 2024, and September 30, 2024, filed with the SEC on May 6, 2024, August 6, 2024, and November 7, 2024, respectively, all of which are incorporated herein by reference, as updated or superseded by the risks and uncertainties described under similar headings in the other documents that are filed after the date hereof and incorporated by reference into this prospectus and any prospectus supplement related to a particular offering.

Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations.
