    Common Stock

    This prospectus supplement supplements the prospectus supplements dated April 30, 2024 and May 3, 2024 and the accompanying prospectus dated April 30, 2024 (collectively the “ATM Prospectus Supplement”), relating to the offer and sales of shares of our common stock, par value $0.0001 per share, having an aggregate offering price of $13,500,000 pursuant to the terms of a sales agreement, as amended (the “sales agreement”), with TD Securities (USA) LLC, the successor in interest to Cowen and Company, LLC (“TD Cowen”). Through the date hereof, we have not sold any shares of our common stock through TD Cowen under the ATM Prospectus Supplement. As of the filing of our Annual Report on Form 10-K on March 28, 2025, we are no longer limited by General Instruction I.B.6 of Form S-3 in the value of securities we may sell in a registered securities offering. In accordance with the terms of the sales agreement, we may offer and sell shares of our common stock, having an aggregate offering price of up to $75,000,000 from time to time through TD Cowen acting as our agent under this prospectus supplement. This prospectus supplement should be read in conjunction with the ATM Prospectus Supplement, and is qualified by reference thereto, except to the extent that the information herein amends or supersedes the information contained in the ATM Prospectus Supplement. This prospectus supplement is not complete without, and may only be delivered or utilized in connection with, the ATM Prospectus Supplement, and any future amendments or supplements thereto.

    Our common stock is listed on the Nasdaq Capital Market under the symbol “WHWK.” On April 24, 2025, the last reported sale price of our common stock on the Nasdaq Capital Market was $1.51 per share.

    Sales of our common stock, if any, under this prospectus supplement and the accompanying prospectus will be made in negotiated transactions, including block trades or block sales, or at market prices by any method that is deemed to be an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended (the “Securities Act”), including without limitation sales made through the Nasdaq Capital Market or on any other trading market for our common stock, or by any other method permitted by law. TD Cowen is not required to sell any specific amount of securities, but will act as our sales agent using commercially reasonable efforts consistent with its normal trading and sales practices, on mutually agreed terms between TD Cowen and us. There is no arrangement for funds to be received in any escrow, trust or similar arrangement.

    The compensation to TD Cowen for sales of common stock pursuant to the sales agreement will be an amount equal to 3.0% of the gross proceeds of any shares of common stock sold under the sales agreement. In connection with the sale of the common stock on our behalf, TD Cowen will be deemed to be an “underwriter” within the meaning of the Securities Act and the compensation of TD Cowen will be deemed to be underwriting commissions or discounts. We have also agreed to provide indemnification and contribution to TD Cowen with respect to certain liabilities, including liabilities under the Securities Act or the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

     

     

    Our business and an investment in our common stock involve significant risks. These risks are described under the caption “Risk Factors” beginning on page S-9 of this prospectus supplement and in the documents incorporated by reference into this prospectus supplement.

    Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense.

    ABOUT THIS PROSPECTUS SUPPLEMENT

    This prospectus supplement is part of a registration statement on Form S-3 that we have filed with the U.S. Securities and Exchange Commission (the “SEC”), utilizing a “shelf” registration process. By using a shelf registration statement, we may offer shares of our common stock having an aggregate offering price of up to $75,000,000 from time to time under this prospectus supplement at prices and on terms to be determined by market conditions at the time of offering. The $75,000,000 of shares of our common stock that may be sold under this prospectus are included in the $150,000,000 of shares of securities that may be sold under the registration statement.

    We provide information to you about this offering of shares of our common stock in two separate documents that are bound together: (1) this prospectus supplement, which describes the specific details regarding this offering; and (2) the accompanying prospectus, which provides general information, some of which may not apply to this offering. Generally, when we refer to this “prospectus,” we are referring to both documents combined. If information in this prospectus supplement is inconsistent with the accompanying prospectus, you should rely on this prospectus supplement. However, if any statement in one of these documents is inconsistent with a statement in another document having a later date—for example, a document incorporated by reference in this prospectus supplement—the statement in the document having the later date modifies or supersedes the earlier statement as our business, financial condition, results of operations and prospects may have changed since the earlier dates.

    We have not, and TD Cowen has not, authorized anyone to provide any information other than that contained in or incorporated by reference in this prospectus supplement, the accompanying prospectus and any free writing prospectus prepared by or on behalf of us or to which we have referred you. We and TD Cowen take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. We are not, and TD Cowen is not, making an offer to sell or soliciting an offer to buy our securities in any jurisdiction where an offer or solicitation is not authorized or in which the person making that offer or solicitation is not qualified to do so or to anyone to whom it is unlawful to make an offer or solicitation. You should assume that the information appearing in this prospectus supplement, the accompanying prospectus, the documents incorporated by reference into this prospectus, and in any free writing prospectus that we may authorize for use in connection with this offering, is accurate only as of the date of those respective documents. Our business, financial condition, results of operations and prospects may have changed since those dates. You should read this prospectus supplement, the accompanying prospectus, the documents incorporated by reference into this prospectus, and any free writing prospectus that we may authorize for use in connection with this offering, in their entirety before making an investment decision. You should also read and consider the information in the documents to which we have referred you in the sections of this prospectus supplement entitled “Where You Can Find More Information” and “Incorporation of Certain Information by Reference.”

    We are offering to sell, and seeking offers to buy, shares of common stock only in jurisdictions where offers and sales are permitted. The distribution of this prospectus and the offering of the common stock in certain jurisdictions may be restricted by law. Persons outside the United States who come into possession of this prospectus must inform themselves about, and observe any restrictions relating to, the offering of the common stock and the distribution of this prospectus outside the United States. This prospectus does not constitute, and may not be used in connection with, an offer to sell, or a solicitation of an offer to buy, any securities offered by this prospectus by any person in any jurisdiction in which it is unlawful for such person to make such an offer or solicitation.

    When we refer to “Whitehawk,” “we,” “our,” “us” and the “Company” in this prospectus, we mean Whitehawk Therapeutics, Inc., unless otherwise specified.

    PROSPECTUS SUPPLEMENT SUMMARY

    This summary provides a general overview of selected information and does not contain all of the information you should consider before buying our common stock. Therefore, you should read the entire prospectus supplement, accompanying prospectus and any free writing prospectus that we have authorized for use in connection with this offering carefully, including the information incorporated by reference herein and therein, before deciding to invest in our common stock. Investors should carefully consider the information set forth under “Risk Factors” beginning on page S-9 of this prospectus supplement and in the documents incorporated by reference into this prospectus supplement.

    Overview

    We are an oncology company applying advanced technologies to established tumor biology that is intended to efficiently deliver improved cancer treatments. We have deep experience in chemistry, formulation, and drug delivery, as well as research, clinical, and commercial pharmaceutical development, resulting in successfully taking product candidates from the clinic to approval, launch, and commercialization.

    We recently entered into an intellectual property license agreement with WuXi Biologics (Shanghai FX) Co., Ltd. (“WuXi Biologics”) for the development and global commercialization of a portfolio of three next generation antibody drug conjugates (“ADCs”) targeting clinically validated, broadly overexpressed tumor antigens in high potential cancer indications with significant unmet need. These ADCs are constructed utilizing an advanced linker-payload platform called CPT113 that has been shown to provide increased stability in blood circulation and deliver targeted release of a Topoisomerase I (“TOPO1”) inhibitor payload into cancer cells.

    These in-licensed assets originated through the collaborative efforts of WuXi Biologics, a leading global contract research, development and manufacturing organization, and Hangzhou DAC Biotechnology (“Hangzhou DAC”), a global leader in ADC innovation, where Hangzhou DAC’s CPT113 linker-payload has been conjugated to novel antibodies developed by WuXi Biologics against three tumor targets: Protein Tyrosine Kinase 7, Mucin 16 (“MUC16”) and Seizure-related Protein 6 (“SEZ6”). The antibody targeting MUC16 targets the membrane-bound form of MUC16 (mMUC16). The antibody targeting SEZ6 is a biparatopic SEZ6 antibody targeting two different epitopes on SEZ6. We believe the resulting ADCs will be able to target cancers expressing these respective tumor markers precisely and deliver the potent, cytotoxic TOPO1 inhibitor at the site of cancer. Each of these ADCs have demonstrated tumor cell binding, tumor cell line cytotoxicity, and in vivo antitumor activity in preclinical models of cancer. We refer to these in-licensed ADC assets as the “ADC Therapies” herein.

    We anticipate submitting three investigational new drug (“IND”) applications with the U.S. Food and Drug Administration (“FDA”) in the coming 12 to 24 months, starting with HWK-007 for the treatment of solid tumors, including non-small cell lung cancer and ovarian cancer, in the second half of 2025; HWK-016 for the treatment of cancers of female origin by the end of 2025; and HWK-206 for the treatment of cancers of neuroendocrine origin in mid-2026. With these three assets, we have the ability to pursue multiple cancer indications with high potential in large addressable patient populations, including and beyond those indications currently expected to be targeted in the upcoming Phase 1 trials.

    Our track record of strong execution of novel drug formulation, research, clinical development, and commercialization in precision oncology, combined with our deep understanding of ADCs positions us

     

    S-4

    to unlock the high potential of this differentiated ADC portfolio. Our management team has extensive experience in the discovery, development, and commercialization of cancer therapeutics, including in senior roles at leading oncology companies. We are supported by our board of directors and specialized scientific advisors, who contribute their deep understanding of drug discovery and development. Furthermore, our investor base includes top life science investors. We believe that our team is well positioned to execute our strategy to develop and, if approved, commercialize the ADC Therapies and future pipeline assets to ultimately bring broad benefit to cancer patients worldwide.

    Legacy FYARRO Business

    Historically, our lead drug product was FYARRO® (sirolimus protein-bound particles for injectable suspension (albumin-bound); nab-sirolimus), which combines two established technologies: nanoparticle albumin-bound (nab) technology and the anti-cancer agent, sirolimus. Nab-sirolimus is a potent inhibitor of the mTOR biological pathway with demonstrated anti-cancer activity in advanced malignant perivascular epithelioid cell tumor (“PEComa”), a rare cancer. We exclusively licensed FYARRO, previously called ABI-009, nab-sirolimus, from Abraxis BioScience, LLC, a wholly owned subsidiary of Celgene Corporation, which is a wholly owned subsidiary of Bristol-Myers Squibb Company and we refer to the development, production and commercial sale of FYARRO herein as the “FYARRO Business.” On February 22, 2022, we launched FYARRO in the United States for treatment of advanced malignant PEComa and recognized net product sales of $26.0 million and $24.4 million for the years ended December 31, 2024 and 2023, respectively.

    On December 19, 2024, we entered into a Stock Purchase Agreement (the “Divestiture Agreement”) with KAKEN INVESTMENTS INC., a Delaware corporation (“Kaken”), KAKEN PHARMACEUTICAL CO., LTD, and Aadi Subsidiary, Inc., a Delaware corporation and our wholly owned subsidiary and the operating company for the FYARRO Business (“Aadi Subsidiary”). Under the Divestiture Agreement, Kaken acquired 100% of the outstanding shares of capital stock of Aadi Subsidiary from us at the closing of the transaction for a purchase price of $102.4 million (following applicable purchase price adjustments under the Divestiture Agreement). The divestiture transaction closed on March 25, 2025 (the “FYARRO Divestiture”) and, as a result, we no longer operate the FYARRO Business.

    About Whitehawk Therapeutics

    We were originally incorporated in the State of Delaware in November 2007 under the name “Zeta Acquisition Corp. II.” Zeta Acquisition Corp. II was a “shell” company registered under the Exchange Act with no specific business plan or purpose until it began operating the business of Aerpio Pharmaceuticals, Inc. through a merger in March 2017. In August 2021, we effected a reverse merger pursuant to which a wholly owned subsidiary of ours, merged with and into Aadi Subsidiary (formerly Aadi Bioscience, Inc.), with Aadi Subsidiary surviving as a wholly owned subsidiary of ours (the “Merger”). Upon the closing of the Merger, we changed our name from “Aerpio Pharmaceuticals, Inc.” to “Aadi Bioscience, Inc.” and the name of Private Aadi was changed from “Aadi Bioscience, Inc.” to “Aadi Subsidiary, Inc.” In connection with the FYARRO Divestiture, Kaken acquired 100% of the outstanding shares of capital stock of Aadi Subsidiary. Upon closing of the transaction, we changed our name from “Aadi Bioscience, Inc.” to “Whitehawk Therapeutics, Inc.”

    Since March 2025, our principal executive offices are located at 2 Headquarters Plaza, East Building, 11th Floor, Morristown, NJ 07960. Prior to March 2025, our principal executive offices were located at 17383 Sunset Boulevard, Suite A250, Pacific Palisades, California 90272.

    RISK FACTORS

    You should consider carefully the risks described below and discussed under the section captioned “Risk Factors” contained in our most recent annual report on Form 10-K as updated by our subsequent filings under the Exchange Act each of which is incorporated by reference in this prospectus supplement in their entirety, together with other information in this prospectus supplement, and the information and documents incorporated by reference in this prospectus supplement, and any free writing prospectus that we have authorized for use in connection with this offering before you make a decision to invest in our common stock. If any of the following events actually occur, our business, operating results, prospects or financial condition could be materially and adversely affected. This could cause the trading price of our common stock to decline and you may lose all or part of your investment. The risks described below are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial may also affect our business operations.

    Risks Relating to this Offering

    Our management team may invest or spend the proceeds of this offering in ways with which you may not agree or in ways which may not yield a significant return.

    Our management will have broad discretion over the use of proceeds from this offering. We intend to use the net proceeds, if any, from this offering for general corporate purposes, which may include, among other things, working capital and funding research and development, and capital expenditures, including the future preclinical and clinical development of the ADC Therapies. Our management will have considerable discretion in the application of the net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. The net proceeds may be used for corporate purposes that do not increase our operating results or enhance the value of our common stock.

    You may experience future dilution as a result of future equity offerings.

    In order to raise additional capital, we expect to in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock. We cannot assure you that we will be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock or other securities convertible into or exchangeable for our common stock in future transactions may be higher or lower than the price per share in this offering. In addition, the issuance of securities in any future financing may dilute your equity ownership and have the effect of depressing the market price for our securities.

    The actual number of shares we will issue under the sales agreement, at any one time or in total, is uncertain.

    Subject to certain limitations in the sales agreement and compliance with applicable law, we have the discretion to deliver a placement notice to TD Cowen at any time throughout the term of the sales agreement. The number of shares that are sold by TD Cowen after delivering a placement notice will fluctuate based on the market price of the common shares during the sales period and limits we set with TD Cowen. Because the price per share of each share sold will fluctuate based on the market price of our common stock during the sales period, it is not possible at this stage to predict the number of shares that will be ultimately issued.

    USE OF PROCEEDS

    We may issue and sell shares of our common stock having aggregate sales proceeds of up to $75,000,000 from time to time. The amount of proceeds from this offering will depend upon the number of shares of our common stock sold and the market price at which they are sold. There can be no assurance that we will be able to sell any shares under or fully utilize the sales agreement with TD Cowen as a source of financing. We intend to use the net proceeds, if any, from this offering for general corporate purposes, which may include, among other things, working capital and funding research and development, and capital expenditures, including the future preclinical and clinical development of the ADC Therapies.

    The amounts and timing of our actual expenditures will depend on numerous factors, including our development and commercialization efforts with respect to product candidates that we may develop in the future, as well as the amount of cash used in our operations. We therefore cannot estimate with certainty the amount of net proceeds to be used for the purposes described above. We may find it necessary or advisable to use the net proceeds for other purposes, and we will have broad discretion in the application of the net proceeds. Pending the uses described above, we plan to invest the net proceeds, if any, from this offering in short-term, investment-grade, interest-bearing securities.

    PLAN OF DISTRIBUTION

    We have previously entered into a sales agreement, dated March 17, 2022, as amended on April 25, 2025, with TD Cowen, under which we may issue and sell from time to time up to $75,000,000 of our common stock through TD Cowen as our sales agent. Sales of our common stock, if any, will be made in negotiated transactions, including block trades or block sales, or at market prices by any method that is deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act, including without limitation sales made through the Nasdaq Capital Market or any other trading market for our common stock, or by any other method permitted by law. Sales pursuant to the sales agreement may be made through an affiliate of TD Cowen.

    TD Cowen will offer our common stock subject to the terms and conditions of the sales agreement on a daily basis or as otherwise agreed upon by us and TD Cowen. We will designate the maximum amount of common stock to be sold through TD Cowen on a daily basis or otherwise determine such maximum amount together with TD Cowen. Subject to the terms and conditions of the sales agreement, TD Cowen will use its commercially reasonable efforts to sell on our behalf all of the shares of common stock requested to be sold by us. We may instruct TD Cowen not to sell common stock if the sales cannot be effected at or above the price designated by us in any such instruction. TD Cowen or we may suspend the offering of our common stock being made through TD Cowen under the sales agreement upon proper notice to the other party. TD Cowen and we each have the right, by giving written notice as specified in the sales agreement, to terminate the sales agreement in each party’s sole discretion at any time.

    The aggregate compensation payable to TD Cowen as sales agent will be equal to 3.0% of the gross sales price of the shares sold through it pursuant to the sales agreement. We have also agreed to reimburse TD Cowen up to $75,000 of TD Cowen’s actual outside legal expenses incurred by TD Cowen in connection with this offering, and for certain other expenses. We estimate that the total expenses of the offering payable by us, excluding commissions and reimbursements payable to TD Cowen under the sales agreement, will be approximately $175,000.

    The remaining sales proceeds, after deducting any expenses payable by us and any transaction fees imposed by any governmental, regulatory, or self-regulatory organization in connection with the sales, will equal our net proceeds for the sale of such common stock.

    TD Cowen will provide written confirmation to us following the close of trading on the Nasdaq Capital Market on each day in which common stock is sold through it as sales agent under the sales agreement. Each confirmation will include the number of shares of common stock sold through it as sales agent on that day, the volume weighted average price of the shares sold, the percentage of the daily trading volume and the gross proceeds to us.

    We will report at least quarterly the number of shares of common stock sold through TD Cowen under the sales agreement and the net proceeds to us in connection with the sales of common stock.

    Settlement for sales of common stock will occur, unless the parties agree otherwise, on the first business day that is also a trading day following the date on which any sales were made in return for payment of the net proceeds to us. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

    In connection with the sales of our common stock on our behalf, TD Cowen will be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to TD Cowen will be deemed to be underwriting commissions or discounts. We have agreed in the sales agreement to provide indemnification and contribution to TD Cowen against certain liabilities, including liabilities

    Our common stock is listed on the Nasdaq Capital Market and trades under the symbol “WHWK.” The transfer agent of our common stock is Equiniti Trust Company, LLC.

    TD Cowen and/or its affiliates have provided, and may in the future provide, various investment banking and other financial services for us and our affiliates, for which services they have received, and may in the future receive, customary fees.

It does not contain all of the information that may be important to you and your investment decision. Before investing in our securities, you should carefully read this entire prospectus, including the matters set forth in the section titled “Risk Factors” and the financial statements and related notes and other information that we incorporate by reference herein, including our Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q.

    Company Overview

    We are a biopharmaceutical company focused on developing and commercializing precision therapies for cancers with alterations in the mTOR pathway, a key regulator of cell growth and cancer progression. Our lead drug product, FYARRO® (sirolimus protein-bound particles for injectable suspension (albumin-bound); nab-sirolimus), combines two established technologies - nanoparticle albumin-bound (nab) technology and the anti-cancer agent, sirolimus. Nab-sirolimus is a potent inhibitor of the mTOR biological pathway with demonstrated anti-cancer activity in our lead indication, advanced malignant perivascular epithelioid cell tumor (“PEComa”), a rare cancer. We believe our approach to utilizing the novel combination of technologies has the potential to produce transformational therapies for patients with cancers beyond PEComa that have known mTOR pathway activation and/or cancers in which other mTOR inhibitors have not been fully exploited due to problems of pharmacology, effective drug delivery, safety, or effective targeting to the disease site.

    On November 22, 2021, the U.S. Food and Drug Administration approved FYARRO sirolimus protein-bound particles for injectable suspension (albumin-bound) for the treatment of adult patients with locally advanced unresectable or metastatic malignant PEComa. On February 22, 2022, we launched FYARRO in the United States for treatment of advanced malignant PEComa and recognized net product sales of $24.4 million and $15.2 million for the years ended December 31, 2023 and 2022, respectively.

    In addition to advanced malignant PEComa, based on exploratory data from the completed Phase 2 registrational study, Advanced Malignant PEComa Trial (“AMPECT”) and data for FYARRO in other solid tumors with TSC1 and TSC2 inactivating alterations, we initiated a registration-directed tumor-agnostic Phase 2 study (“PRECISION1”) of FYARRO in patients with Tuberous Sclerosis Complex 1 (“TSC1”) and Tuberous Sclerosis Complex 2 (“TSC2”) alterations. The PRECISION1 trial was opened for enrollment in the United States during the first quarter of 2022, with dosing of our first patient in March 2022.

    On December 14, 2023, we reported results from a planned interim analysis on the first third of participants in the PRECISION1 trial. The interim analysis included data from the first third of trial participants (n=40) with a minimum of 4.5 months of follow-up, including investigator-assessed response and safety analyzed separately in each of the TSC1 and TSC2 arms. Nine different tumor types were enrolled in the TSC1 arm and 13 tumor types were enrolled in the TSC2 arm.

    With respect to the efficacy of nab-sirolimus in patients with tumors harboring pathogenic inactivating alteration in TSC1, of the 22 patients enrolled, 19 patients received ≥ 1 post baseline scan and were evaluable for efficacy. Observations included:

     

      •  

    A 26% Overall Response Rate (ORR) including 5 partial responses (PR) with 4 confirmed responses and 1 unconfirmed response (uPR). The patient with uPR remains on treatment and is awaiting a confirmatory scan

     

    1


    Table of Contents
      •  

    9 patients had stable disease (SD), 3 of which were greater than or equal to six months in duration, resulting in a clinical benefit rate of 42% (5 PR + 3 SD ≥ 6 months)

     

      •  

    Patients were heavily pre-treated with median of 3 prior lines of therapy

     

      •  

    Median time to response was 1.4 months and all responses were ongoing at time of data cutoff

     

      •  

    Responses were seen across four different epithelial carcinomas

     

      •  

    60% of responders experienced > 50% tumor reduction

    With respect to the efficacy of nab-sirolimus in patients with tumors harboring pathogenic inactivating alteration in TSC2, of the 18 patients enrolled, all 18 patients received ≥ 1 post baseline scan and were evaluable for efficacy. Observations included:

     

      •  

    An 11% ORR including 2 PRs with 1 confirmed and 1 uPR

     

      •  

    12 patients had SD, 3 of which were greater than or equal to six months resulting in a clinical benefit rate of 28% (2 PR + 3 SD ≥ 6 mos)

     

      •  

    Patients were heavily pre-treated with median of 3.5 prior lines of therapy; 50% had ≥ 5 prior lines of therapy

     

      •  

    Responses were seen in one epithelial carcinoma and one sarcoma

    No new safety signals were observed, and no grade four treatment-related events or deaths occurred. One patient discontinued the study due to grade two pneumonitis that completely resolved after discontinuation of therapy. Across both arms, the safety profile was consistent with the nab-sirolimus label and the mTOR inhibitor drug class.

    As of December 14, 2023, 80 patients were enrolled in the PRECISION1 trial, supporting the two-thirds interim analysis expected in the third quarter of 2024. The ORR analysis in this cohort will be based on independent radiological review with a minimum of six months of follow-up for all patients. The trial is expected to be completed by the end of 2024 with results anticipated in early 2025.

    On August 9, 2023, we announced the expansion of our FYARRO pipeline through the further investigation of mTOR pathway inhibition in endometrial cancer and neuroendocrine tumors (NETs). As part of our continued evaluation of potential new clinical programs for FYARRO, either as a single agent or in combination with other targeted therapies, we selected these new clinical indications based on preclinical data supporting these programs, which we believe are promising, and the prospect of providing enhanced therapeutic benefit in these indications with meaningful patient populations and high unmet needs.

    We are currently enrolling patients in a Phase 2 open-label, multi-institutional study to evaluate the efficacy and safety of the combination of FYARRO with letrozole for the treatment of advanced or recurrent endometrioid-type endometrial cancer (EEC) and a Phase 2 multicenter, open-label, single-arm trial to evaluate FYARRO in adult patients with functional or non-functional, well-differentiated, locally advanced unresectable or metastatic NETs of the GI tract, lung, or pancreas who have received no more than two prior lines of therapy.

    In October 2022, we entered into a collaboration and supply agreement with Mirati Therapeutics, Inc. (“Mirati”) to evaluate the combination of Mirati’s adagrasib, a KRASG12C selective inhibitor, and FYARRO in KRASG12C mutant non-small cell lung cancer (NSCLC) and other solid tumors. Under the terms of the agreement, Mirati will be responsible for sponsoring and operating the Phase 1/2 study and we will supply study drug and jointly share the cost of the study. The primary objective of this multi-center, single-arm, open-label Phase 1/2 trial is to determine the optimal dose and recommended Phase 2 dose for the combination of adagrasib and FYARRO in patients with KRASG12C-mutant solid tumors. In addition, the study will investigate the safety, tolerability and efficacy of adagrasib and FYARRO in combination in patients both with and without prior

    exposure to a KRASG12C inhibitor. The trial will build on preclinical data showing enhanced anti-tumor efficacy with the combination of adagrasib and FYARRO relative to either agent alone. In August 2023, we announced that the first patient dosing occurred in the Phase 1/2 trial.

    Corporate Information

    We were originally incorporated in the State of Delaware in November 2007 under the name “Zeta Acquisition Corp. II.” Zeta Acquisition Corp. II was a “shell” company registered under the Exchange Act with no specific business plan or purpose until it began operating the business of Aerpio Pharmaceuticals, Inc. through a merger in March 2017. In August 2021, we effected a reverse merger pursuant to which a wholly owned subsidiary of ours, merged with and into Aadi Subsidiary, Inc. (formerly Aadi Bioscience, Inc.) (“Private Aadi”), with Private Aadi surviving as a wholly owned subsidiary of ours (the “Merger”). Upon the closing of the Merger, we changed our name from “Aerpio Pharmaceuticals, Inc.” to “Aadi Bioscience, Inc.” and the name of Private Aadi was changed from “Aadi Bioscience, Inc.” to “Aadi Subsidiary, Inc.”

    Our principal executive offices are located at 17383 Sunset Boulevard, Suite A250, Pacific Palisades, California 90272. We maintain a website at www.aadibio.com, to which we regularly post copies of our press releases as well as additional information about us. Our filings with the Securities and Exchange Commission (the “SEC”) will be available free of charge through the website as soon as reasonably practicable after being electronically filed with or furnished to the SEC.

    Debt Securities

    We may issue debt securities, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. The subordinated debt securities will be subordinate and junior in priority of payment to certain of our other indebtedness to the extent described in a prospectus supplement or free writing prospectus. The senior debt securities will rank equally in right of payment to all our other senior unsecured debt. Unless the context requires otherwise, whenever we refer to the “indentures,” we are also referring to any supplemental indentures that specify the terms of a particular series of debt securities.

    The debt securities will be issued under an indenture between us and a trustee to be identified in an accompanying prospectus supplement. We have summarized the general features of the debt securities to be governed by the indentures in this prospectus and the forms of indenture have been filed as an exhibit to the registration statement of which this prospectus forms a part. We encourage you to read the indenture.

    Warrants

    We may offer warrants for the purchase of common stock, preferred stock, debt securities or depositary shares. We may offer warrants independently or together with other securities.

    Units

    We may offer units comprised of one or more of the other classes of securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit.

The prospectus supplement applicable to each offering of our securities will contain a discussion of the risks applicable to an investment in our securities. Prior to making a decision about investing in our securities, you should carefully consider the specific risk factors discussed in the section of the applicable prospectus supplement titled “Risk Factors,” 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 “Part I—Item 1A—Risk Factors” of our most recent Annual Report on Form 10-K and in “Part II—Item 1A—Risk Factors” in our most recent Quarterly Report on Form 10-Q filed subsequent to such Form 10-K that are incorporated herein by reference, as may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations.

    FORWARD-LOOKING STATEMENTS

    This prospectus, each prospectus supplement and the information incorporated by reference in this prospectus and each prospectus supplement contain certain statements that constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “could,” “would,” “project,” “plan,” “potentially,” “likely,” and similar expressions and variations thereof are intended to identify forward-looking statements, but are not the exclusive means of identifying such statements. Those statements appear in this prospectus, any accompanying prospectus supplement and the documents incorporated herein and therein by reference, particularly in the sections titled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and include statements regarding the intent, belief or current expectations of our management that are subject to known and unknown risks, uncertainties and assumptions. You are cautioned that any such forward-looking statements are not guarantees of future performance and involve risks and uncertainties, and that actual results may differ materially from those projected in the forward-looking statements as a result of various factors.

    Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely upon forward-looking statements as predictions of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. Except as required by applicable law, including the securities laws of the United States and the rules and regulations of the SEC, we do not plan to publicly update or revise any forward-looking statements contained herein after we distribute this prospectus, whether as a result of any new information, future events or otherwise.

    In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this prospectus, and although we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted a thorough inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

    This prospectus and the documents incorporated by reference in this prospectus may contain market data that we obtain from industry sources. These sources do not guarantee the accuracy or completeness of the information. Although we believe that our industry sources are reliable, we do not independently verify the

    information. The market data may include projections that are based on a number of other projections. While we believe these assumptions to be reasonable and sound as of the date of this prospectus, actual results may differ from the projections.

    USE OF PROCEEDS

    We will set forth in the prospectus supplement our intended use for the net proceeds received from the sale of any securities. We will retain broad discretion over the use of the net proceeds to us from the sale of our securities under this prospectus.

    DESCRIPTION OF CAPITAL STOCK

    The description of our capital stock is incorporated by reference to Exhibit 4.1 to our Annual Report on Form 10-K for the fiscal year ended December  31, 2023, filed with the SEC on March 13, 2024.

    DESCRIPTION OF DEBT SECURITIES

    This section describes the general terms and provisions of our debt securities that we may issue from time to time. We may issue debt securities, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. While the terms we have summarized below will apply generally to any future debt securities we may offer under this prospectus, the applicable prospectus supplement or free writing prospectus will describe the specific terms of any debt securities offered through that prospectus supplement or free writing prospectus. The terms of any debt securities we offer under a prospectus supplement or free writing prospectus may differ from the terms we describe below. Unless the context requires otherwise, whenever we refer to the “indentures,” we are also referring to any supplemental indentures that specify the terms of a particular series of debt securities.

    We will issue any senior debt securities under the senior indenture that we will enter into with the trustee named in the senior indenture. We will issue any subordinated debt securities under the subordinated indenture that we will enter into with the trustee named in the subordinated indenture. We have filed forms of these documents as exhibits to the registration statement, of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the SEC.

    The indentures will be qualified under the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act. We use the term “trustee” to refer to either the trustee under the senior indenture or the trustee under the subordinated indenture, as applicable.

    The following summaries of material provisions of the senior debt securities, the subordinated debt securities and the indentures are subject to, and qualified in their entirety by reference to, all of the provisions of the indenture applicable to a particular series of debt securities. We urge you to read the applicable prospectus supplement or free writing prospectus and any related free writing prospectuses related to the debt securities that we may offer under this prospectus, as well as the complete applicable indenture that contains the terms of the debt securities. Except as we may otherwise indicate, the terms of the senior indenture and the subordinated indenture are identical.

    Conversion or Exchange Rights

    We will set forth in the applicable prospectus supplement or free writing prospectus the terms on which a series of debt securities may be convertible into or exchangeable for our common stock, our preferred stock or other securities (including securities of a third-party). We will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of shares of our common stock, our preferred stock or other securities (including securities of a third-party) that the holders of the series of debt securities receive would be subject to adjustment.

    Consolidation, Merger or Sale

    Unless we provide otherwise in the prospectus supplement or free writing prospectus applicable to a particular series of debt securities, the indentures will not contain any covenant that restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose of all or substantially all of our assets. However, any successor to or acquirer of such assets must assume all of our obligations under the indentures or the debt securities, as appropriate. If the debt securities are convertible into or exchangeable for other securities of ours or securities of other entities, the person with whom we consolidate or merge or to whom we sell all of our property must make provisions for the conversion of the debt securities into securities that the holders of the debt securities would have received if they had converted the debt securities before the consolidation, merger or sale.

    Events of Default Under the Indenture

    Unless we provide otherwise in the prospectus supplement or free writing prospectus applicable to a particular series of debt securities, the following are events of default under the indentures with respect to any series of debt securities that we may issue:

     

      •  

    if we fail to pay interest when due and payable and our failure continues for 90 days and the time for payment has not been extended;

     

      •  

    if we fail to pay the principal, premium or sinking fund payment, if any, when due and payable at maturity, upon redemption or repurchase or otherwise, and the time for payment has not been extended;

     

      •  

    if we fail to observe or perform any other covenant contained in the debt securities or the indentures, other than a covenant specifically relating to another series of debt securities, and our failure continues for 90 days after we receive notice from the trustee or holders of at least 25% in aggregate principal amount of the outstanding debt securities of the applicable series; and

     

      •  

    if specified events of bankruptcy, insolvency or reorganization occur.

    We will describe in each applicable prospectus supplement or free writing prospectus any additional events of default relating to the relevant series of debt securities.

    If an event of default with respect to debt securities of any series occurs and is continuing, other than an event of default specified in the last bullet point above, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series, by notice to us in writing, and to the trustee if notice is given by such holders, may declare the unpaid principal, premium, if any, and accrued interest, if any,

     

    9


    Table of Contents

    due and payable immediately. If an event of default specified in the last bullet point above occurs with respect to us, the unpaid principal, premium, if any, and accrued interest, if any, of each issue of debt securities then outstanding shall be due and payable without any notice or other action on the part of the trustee or any holder.

    The holders of a majority in principal amount of the outstanding debt securities of an affected series may waive any default or event of default with respect to the series and its consequences, except defaults or events of default regarding payment of principal, premium, if any, or interest, unless we have cured the default or event of default in accordance with the indenture. Any waiver shall cure the default or event of default.

    Subject to the terms of the indentures, if an event of default under an indenture shall occur and be continuing, the trustee will be under no obligation to exercise any of its rights or powers under such indenture at the request or direction of any of the holders of the applicable series of debt securities, unless such holders have offered the trustee reasonable indemnity or security satisfactory to it against any loss, liability or expense. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the debt securities of that series, provided that:

     

      •  

    the direction so given by the holder is not in conflict with any law or the applicable indenture; and

     

      •  

    subject to its duties under the Trust Indenture Act, the trustee need not take any action that might involve it in personal liability or might be unduly prejudicial to the holders not involved in the proceeding.

    A holder of the debt securities of any series will have the right to institute a proceeding under the indentures or to appoint a receiver or trustee, or to seek other remedies if:

     

      •  

    the holder has given written notice to the trustee of a continuing event of default with respect to that series;

     

      •  

    the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made written request, and such holders have offered reasonable indemnity to the trustee or security satisfactory to it against any loss, liability or expense or to be incurred in compliance with instituting the proceeding as trustee; and

     

      •  

    the trustee does not institute the proceeding, and does not receive from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series other conflicting directions within 90 days after the notice, request and offer.

    These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities, or other defaults that may be specified in the applicable prospectus supplement or free writing prospectus.

    We will periodically file statements with the trustee regarding our compliance with specified covenants in the indentures.

    Modification of Indenture; Waiver

    Subject to the terms of the indenture for any series of debt securities that we may issue, we and the trustee may change an indenture without the consent of any holders with respect to the following specific matters:

     

      •  

    to fix any ambiguity, defect or inconsistency in the indenture;

     

      •  

    to comply with the provisions described above under “—Consolidation, Merger or Sale;”

     

      •  

    to comply with any requirements of the SEC in connection with the qualification of any indenture under the Trust Indenture Act;

     

    10


    Table of Contents
      •  

    to add to, delete from or revise the conditions, limitations, and restrictions on the authorized amount, terms, or purposes of issue, authentication and delivery of debt securities, as set forth in the indenture;

     

      •  

    to provide for the issuance of and establish the form and terms and conditions of the debt securities of any series as provided under “Description of Debt Securities—General,” to establish the form of any certifications required to be furnished pursuant to the terms of the indenture or any series of debt securities, or to add to the rights of the holders of any series of debt securities;

     

      •  

    to evidence and provide for the acceptance of appointment hereunder by a successor trustee;

     

      •  

    to provide for uncertificated debt securities and to make all appropriate changes for such purpose;

     

      •  

    to add to our covenants such new covenants, restrictions, conditions or provisions for the benefit of the holders, to make the occurrence, or the occurrence and the continuance, of a default in any such additional covenants, restrictions, conditions or provisions an event of default or to surrender any right or power conferred to us in the indenture; or

     

      •  

    to change anything that does not materially adversely affect the interests of any holder of debt securities of any series.

    In addition, under the indentures, the rights of holders of a series of debt securities may be changed by us and the trustee with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each series that is affected. However, subject to the terms of the indenture for any series of debt securities that we may issue or as otherwise provided in the prospectus supplement or free writing prospectus applicable to a particular series of debt securities, we and the trustee may make the following changes only with the consent of each holder of any outstanding debt securities affected:

     

      •  

    extending the stated maturity of the series of debt securities;

     

      •  

    reducing the principal amount, reducing the rate of or extending the time of payment of interest, or reducing any premium payable upon the redemption or repurchase of any debt securities; or

     

      •  

    reducing the percentage of debt securities, the holders of which are required to consent to any amendment, supplement, modification or waiver.

    Discharge

    Each indenture provides that, subject to the terms of the indenture and any limitation otherwise provided in the prospectus supplement or free writing prospectus applicable to a particular series of debt securities, we can elect to be discharged from our obligations with respect to one or more series of debt securities, except for specified obligations, including obligations to:

     

      •  

    register the transfer or exchange of debt securities of the series;

     

      •  

    replace stolen, lost or mutilated debt securities of the series;

     

      •  

    maintain paying agencies;

     

      •  

    hold monies for payment in trust;

     

      •  

    recover excess money held by the trustee;

     

      •  

    compensate and indemnify the trustee; and

     

      •  

    appoint any successor trustee.

    In order to exercise our rights to be discharged, we must deposit with the trustee money or government obligations sufficient to pay all the principal of, any premium and interest on, the debt securities of the series on the dates payments are due.

    Form, Exchange and Transfer

    We will issue the debt securities of each series only in fully registered form without coupons and, unless we otherwise specify in the applicable prospectus supplement or free writing prospectus, in denominations of $1,000 and any integral multiple thereof. The indentures provide that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, The Depository Trust Company or another depository named by us and identified in a prospectus supplement or free writing prospectus with respect to that series.

    At the option of the holder, subject to the terms of the indentures and the limitations applicable to global securities described in the applicable prospectus supplement or free writing prospectus, the holder of the debt securities of any series can exchange the debt securities for other debt securities of the same series, in any authorized denomination and of like tenor and aggregate principal amount.

    Subject to the terms of the indentures and the limitations applicable to global securities set forth in the applicable prospectus supplement or free writing prospectus, holders of the debt securities may present the debt securities for exchange or for registration of transfer, duly endorsed or with the form of transfer endorsed thereon duly executed if so required by us or the security registrar, at the office of the security registrar or at the office of any transfer agent designated by us for this purpose. Unless otherwise provided in the debt securities that the holder presents for transfer or exchange, we will make no service charge for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges.

    We will name in the applicable prospectus supplement or free writing prospectus the security registrar, and any transfer agent in addition to the security registrar, that we initially designate for any debt securities. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series. If we elect to redeem the debt securities of any series, we will not be required to:

     

      •  

    issue, register the transfer of, or exchange any debt securities of that series during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of any debt securities that may be selected for redemption and ending at the close of business on the day of the mailing; or

     

      •  

    register the transfer of or exchange any debt securities so selected for redemption, in whole or in part, except the unredeemed portion of any debt securities we are redeeming in part.

    Information Concerning the Trustee

    The trustee, other than during the occurrence and continuance of an event of default under an indenture, undertakes to perform only those duties as are specifically set forth in the applicable indenture. Upon an event of default under an indenture, the trustee must use the same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs.

    Subject to this provision, the trustee is under no obligation to exercise any of the powers given it by the indentures at the request of any holder of debt securities unless it is offered reasonable security and indemnity against the costs, expenses and liabilities that it might incur.

    Payment and Paying Agents

    Unless we otherwise indicate in the applicable prospectus supplement or free writing prospectus, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.

     

    12


    Table of Contents

    We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that unless we otherwise indicate in the applicable prospectus supplement or free writing prospectus, we will make interest payments by check that we will mail to the holder or by wire transfer to certain holders. Unless we otherwise indicate in the applicable prospectus supplement or free writing prospectus, we will designate the corporate trust office of the trustee as our sole paying agent for payments with respect to debt securities of each series. We will name in the applicable prospectus supplement or free writing prospectus any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

    All money we pay to a paying agent or the trustee for the payment of the principal of or any premium or interest on any debt securities that remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the debt security thereafter may look only to us for payment thereof.

    Governing Law

    The indentures and the debt securities will be governed by and construed in accordance with the laws of the State of Ohio, except to the extent that the Trust Indenture Act is applicable.

    Ranking of Debt Securities

    The subordinated debt securities will be subordinate and junior in priority of payment to certain of our other indebtedness to the extent described in a prospectus supplement or free writing prospectus. The subordinated indenture does not limit the amount of subordinated debt securities that we may issue. It also does not limit us from issuing any other secured or unsecured debt.

    The senior debt securities will rank equally in right of payment to all our other senior unsecured debt. The senior indenture does not limit the amount of senior debt securities that we may issue. It also does not limit us from issuing any other secured or unsecured debt.

    DESCRIPTION OF UNITS

    We may offer units comprising two or more securities described in this prospectus in any combination. For example, we might issue units consisting of a combination of common stock and warrants to purchase common stock. The following description sets forth certain general terms and provisions of the units that we may offer pursuant to this prospectus. The particular terms of the units and the extent, if any, to which the general terms and provisions may apply to the units so offered will be described in the applicable prospectus supplement.

    Each unit will be issued so that the holder of the unit also is the holder of each security included in the unit. Thus, the unit will have the rights and obligations of a holder of each included security. Units will be issued pursuant to the terms of a unit agreement, which may provide that the securities included in the unit may not be held or transferred separately at any time or at any time before a specified date. A copy of the forms of the unit agreement and the unit certificate relating to any particular issue of units will be filed with the SEC each time we issue units, and you should read those documents for provisions that may be important to you. For more information on how you can obtain copies of the forms of the unit agreement and the related unit certificate, see the section titled “Where You Can Find More Information.”

    The prospectus supplement relating to any particular issuance of units will describe the terms of those units, including, to the extent applicable, the following:

     

      •  

    the designation and terms of the units and the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

     

      •  

    any provision for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units; and

     

      •  

    whether the units will be issued in fully registered or global form.

    PLAN OF DISTRIBUTION

    We may sell securities:

     

      •  

    through underwriters;

     

      •  

    through dealers;

     

      •  

    through agents;

     

      •  

    directly to purchasers; or

     

      •  

    through a combination of any of these methods of sale.

    In addition, we may issue the securities as a dividend or distribution or in a subscription rights offering to our existing securityholders.

    We may directly solicit offers to purchase securities or agents may be designated to solicit such offers. We will, in the prospectus supplement relating to such offering, name any agent that could be viewed as an underwriter under the Securities Act and describe any commissions that we must pay. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis. This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement.

    The distribution of the securities may be effected from time to time in one or more transactions:

     

      •  

    at a fixed price or prices that may be changed from time to time;

     

    15


    Table of Contents
      •  

    at market prices prevailing at the time of sale;

     

      •  

    at prices related to such prevailing market prices; or

     

      •  

    at negotiated prices.

    Each prospectus supplement will describe the method of distribution of the securities and any applicable restrictions.

    The prospectus supplement with respect to the securities of a particular series will describe the terms of the offering of the securities, including the following:

     

      •  

    the name of the agent or any underwriters;

     

      •  

    the public offering or purchase price;

     

      •  

    any discounts and commissions to be allowed or paid to the agent or underwriters;

     

      •  

    all other items constituting underwriting compensation;

     

      •  

    any discounts and commissions to be allowed or paid to dealers; and

     

      •  

    any exchanges on which the securities will be listed.

    If any underwriters or agents are utilized in the sale of the securities in respect of which this prospectus is delivered, we will enter into an underwriting agreement or other agreement with them at the time of sale to them, and we will set forth in the prospectus supplement relating to such offering the names of the underwriters or agents and the terms of the related agreement with them.

    If a dealer is utilized in the sale of the securities in respect of which the prospectus is delivered, we will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale.

    If we offer securities in a subscription rights offering to our existing securityholders, we may enter into a standby underwriting agreement with dealers, acting as standby underwriters. We may pay the standby underwriters a commitment fee for the securities they commit to purchase on a standby basis. If we do not enter into a standby underwriting arrangement, we may retain a dealer-manager to manage a subscription rights offering for us.

    Agents, underwriters, dealers and other persons may be entitled under agreements that they may enter into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act.

    If so indicated in the applicable prospectus supplement, we will authorize underwriters or other persons acting as our agents to solicit offers by certain institutions to purchase securities from us pursuant to delayed delivery contracts providing for payment and delivery on the date stated in the prospectus supplement. Each contract will be for an amount not less than, and the aggregate amount of securities sold pursuant to such contracts shall not be less nor more than, the respective amounts stated in the prospectus supplement. Institutions with whom the contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but shall in all cases be subject to our approval. Delayed delivery contracts will not be subject to any conditions except that:

     

      •  

    the purchase by an institution of the securities covered under that contract shall not at the time of delivery be prohibited under the laws of the jurisdiction to which that institution is subject; and

     

      •  

    if the securities are also being sold to underwriters acting as principals for their own account, the underwriters shall have purchased such securities not sold for delayed delivery.

     

    16


    Table of Contents

    The underwriters and other persons acting as agents will not have any responsibility in respect of the validity or performance of delayed delivery contracts.

    Certain agents, underwriters and dealers, and their associates and affiliates may be customers of, have borrowing relationships with, engage in other transactions with, and/or perform services, including investment banking services, for us or one or more of our respective affiliates in the ordinary course of business.

    In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may over-allot in connection with the offering, creating a short position for their own accounts. In addition, to cover over-allotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.

    Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. In February 2023, Rule 15c6-1 of the Exchange Act was amended to require, effective May 28, 2024, trades in the secondary market to settle in one business day, unless the parties to any such trade expressly agree otherwise. The applicable prospectus supplement may provide that the original issue date for your securities may be more than two scheduled business days after the trade date for your securities. Accordingly, in such a case, if you wish to trade securities on any date prior to the third business day before the original issue date for your securities, you will be required, by virtue of the fact that your securities initially are expected to settle in more than three scheduled business days after the trade date for your securities, to make alternative settlement arrangements to prevent a failed settlement.

    The securities may be new issues of securities and may have no established trading market. The securities may or may not be listed on a national securities exchange. We can make no assurance as to the liquidity of or the existence of trading markets for any of the securities.
