PROSPECTUS

17,629,522 Shares of Common Stock

This prospectus covers the offer and resale from time to time of up to 17,629,522 shares (the “Shares”) of common stock, par value $0.0001 per share, of Aadi Bioscience, Inc. (formerly known as Aerpio Pharmaceuticals, Inc. (“Aerpio”)), a Delaware corporation (the “Company”), by the selling stockholders identified in this prospectus, including their transferees, pledgees or donees or their respective successors. The Shares offered by the selling stockholders consist of: (i) 5,776,660 shares that were privately issued pursuant to an Agreement and Plan of Merger, dated May 16, 2021 (the “Merger Agreement”), by and among the Company, Aspen Merger Subsidiary, Inc. (“Merger Sub”), and Aadi Subsidiary, Inc. (formerly known as Aadi Bioscience, Inc. (“Private Aadi”)), pursuant to which Merger Sub merged with and into Private Aadi, with Private Aadi surviving as a wholly-owned subsidiary of the Company (the “Merger”), and (ii) 11,852,862 shares that were sold and issued to certain of the selling stockholders in a private placement pursuant to a Subscription Agreement, dated May 16, 2021, which closed on August 26, 2021 (the “PIPE Financing”). As a result of the Merger, the outstanding shares of common stock of Private Aadi were converted into the right to receive shares of our common stock on the terms set forth in the Merger Agreement. For accounting purposes, Private Aadi is considered to have acquired Aerpio in the Merger.

The selling stockholders identified in this prospectus may offer the shares of common stock pursuant to this prospectus from time to time through public or private transactions at fixed prices, at market prices prevailing at the time of sale, at prices related to prevailing market prices or at privately negotiated prices. The selling stockholders may sell shares to or through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, concessions or commissions from the selling stockholders, the purchasers of the shares, or both. For additional information on the methods of sale that may be used by the selling stockholders, see the section entitled “Plan of Distribution” on page 16. For a list of the selling stockholders, see the section entitled “Selling Stockholders” on page 10.

We are not selling any shares of common stock under this prospectus and will not receive any proceeds from the sale by the selling stockholders of such shares. We are paying the cost of registering the shares of common stock covered by this prospectus as well as various related expenses. The selling stockholders are responsible for all selling commissions, transfer taxes and other costs related to the offer and sale of their shares.

Company Overview

We are a clinical-stage biopharmaceutical company developing precision therapies for genetically-defined cancers with alterations in mTOR pathway genes. Our lead drug candidate, ABI-009 (FYARRO^TM, nab-sirolimus), is a form of sirolimus bound to albumin. Sirolimus is a potent inhibitor of the mTOR biological pathway, the activation of which pathway can promote tumor growth, and inhibits downstream signaling from mTOR. We are evaluating ABI-009 in cancers with known mTOR pathway activation, including tumor agnostic indications targeting specific genomic alterations that activate the mTOR pathway.

In May 2021, we completed the filing of a rolling new drug application (“NDA”) for ABI-009 to the U.S. Food and Drug Administration (the “FDA”), for approval to treat patients with advanced malignant perivascular epithelioid cell tumors (“PEComa”), and the FDA accepted the NDA in July 2021 and granted us Priority Review designation with a Prescription Drug User Fee Act (“PDUFA”) target action date of November 26, 2021. Our NDA is based on results from our Phase 2 registrational study AMPECT (Advanced Malignant PEComa Trial), in advanced malignant PEComa for which there are currently no approved therapies in the U.S. and for which there has never been a prior prospective clinical trial. In November 2019, we announced top-line results from the AMPECT study, including that the study achieved its primary endpoint of overall response rate (“ORR”), as determined by blinded independent central radiologic review using modified Response Evaluation Criteria in Solid Tumors, RECIST v1.1.

We are actively engaged in commercial preparations to support the planned U.S. launch of ABI-009 for the treatment of patients with advanced malignant PEComa, if approved. We intend to build a specialist sales force to target physicians in the United States who treat advanced malignant PEComa.

In addition to advanced malignant PEComa, based on data from the completed AMPECT trial and our ongoing expanded access program, we are planning a registrational Phase 2 study (“PRECISION 1”) of ABI-009 in tumor-agnostic Tuberous Sclerosis Complex 1 and 2 (TSC1 & TSC2) alterations. We have completed a Type B meeting with the FDA in which Aadi discussed the initial trial design with the FDA. Aadi plans to initiate the PRECISION 1 trial by the end of 2021.

We have an exclusive license with Abraxis BioScience, LLC, a wholly owned subsidiary of Bristol-Myers Squibb Company, under which we obtained exclusive rights to develop, manufacture, and commercialize ABI-009, provided that we have granted to EOC Pharma (Hong Kong) Limited exclusive rights to develop and commercialize ABI-009 for the Greater China region.

Company Information

We were originally incorporated in the State of Delaware in November 2007 under the name “Zeta Acquisition Corp. II.” Prior to the merger with Aerpio Pharmaceuticals, Inc., Zeta Acquisition Corp. II was a “shell” company registered under the Exchange Act with no specific business plan or purpose until it began

1

operating the business of Aerpio through the merger on March 15, 2017 (the “Aerpio Merger”). On August 26, 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. On August 26, 2021, we changed our name from Aerpio Pharmaceuticals, Inc. to Aadi Bioscience, Inc.

Our principal executive offices are located at 17383 Sunset Blvd., Suite A250, Pacific Palisades, CA 90272 and our telephone number is (424) 473-8055. Our corporate website address is www.aadibio.com. Our website and the information contained on, or that can be accessed through, the website will not be deemed to be incorporated by reference in, and are not considered part of, this filing. You should not rely on any such information in making your decision whether to purchase Aadi common stock. We make available free of charge through our website our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act, as soon as reasonably practicable after we electronically file such material with, or furnish it to, the SEC. The information contained in, or that can be accessed through, our website is not part of this prospectus.

Merger Transaction and Reverse Stock Split

On August 26, 2021, we completed our previously announced merger transaction with Private Aadi in accordance with the terms of the Agreement and Plan of Merger, dated as of May 16, 2021 (the “Merger Agreement”), by and among us, a wholly-owned subsidiary of ours (“Merger Sub”), and Private Aadi. Pursuant to the terms of the Merger Agreement, Merger Sub merged with and into Private Aadi with Private Aadi surviving as our wholly-owned subsidiary (the “Merger”).

On August 26, 2021, in connection with, and prior to the completion of, the Merger, we effected a 1-for-15 reverse stock split of our common stock (the “Reverse Stock Split”). Under the terms of the Merger Agreement, we issued common stock to holders of Private Aadi capital stock at an exchange ratio of 0.3172, after giving effect to the Reverse Stock Split, for each share of Private Aadi capital stock outstanding immediately prior to the Merger. Immediately after the completion of the Merger, Private Aadi changed its name from “Aadi Bioscience, Inc.” to “Aadi Subsidiary, Inc.” and we changed our name from “Aerpio Pharmaceuticals, Inc.” to “Aadi Bioscience, Inc.” In connection with the closing of the Merger, our stock began trading on the Nasdaq Capital Market under the symbol “AADI” on August 27, 2021. Private Aadi was determined to be the accounting acquirer, our historical financials will be those of Private Aadi and the business conducted by Private Aadi became the business conducted by us. Our global headquarters are located at 17383 Sunset Boulevard, Suite A250, Pacific Palisades, California 90272.

Pursuant to the Merger Agreement, we agreed to file, no later than 30 days after the closing of the Merger, a registration statement with the Securities and Exchange Commission (the “SEC”) covering the resale of the shares of common stock acquired by the holders of capital stock of Private Aadi, in connection with the Merger, and to use commercially reasonable efforts to cause such registration statement to become effective as soon as practicable.

The description of the Merger Agreement is not complete and is qualified in its entirety by reference to the Merger Agreement, which has been filed as an exhibit to our Current Report on Form 8-K, filed on May 17, 2021. See “Where You Can Find More Information” and “Information Incorporated by Reference.” The representations, warranties and covenants made by us in such agreement were made solely for the benefit of the parties to such agreement, including, in some cases, for the purpose of allocating risk among the parties thereto, and should not be deemed to be a representation, warranty or covenant to you. Moreover, such representations, warranties or covenants were made as of an earlier date. Accordingly, such representations, warranties and covenants should not be relied on as accurately representing the current state of our affairs

PIPE Financing and Subscription Agreement

On May 16, 2021, we entered into a subscription agreement ( “Subscription Agreement”) with certain of the selling stockholders named in this prospectus (the “PIPE Investors”), pursuant to which we sold shares of our common stock concurrently with the closing of the Merger. At the closing of the PIPE Financing, we entered into a Registration Rights Agreement, dated August 26, 2021 (“Registration Rights Agreement”), with the selling stockholders named in this prospectus.

At the closing of the PIPE Financing, on August 26, 2021 we sold and issued to the selling stockholders 11,852,862 shares of our common stock at a purchase price of $13.077 per share. The total purchase price paid by the selling stockholders in the closing was approximately $155.0 million.

The shares of common stock issued to the PIPE Investors were not initially registered under the Securities Act or any state securities laws. We have relied on the exemption from the registration requirements of the Securities Act by virtue of Section 4(a)(2) thereof and Regulation D of the Securities Act. In connection with their execution of the Subscription Agreement, each of the PIPE Investors represented to us that such PIPE Investor is an “accredited investor” as defined in Regulation D of the Securities Act and that the shares of common stock purchased by such PIPE Investor were being acquired solely for its own account and for investment purposes and not with a view to its future sale or distribution.

On August 26, 2021, in connection with the PIPE Financing, we entered into a Registration Rights Agreement with the PIPE Investors (the “Registration Rights Agreement”). Under the terms of the Registration Rights Agreement, we agreed to prepare and file, within 30 days after the closing, one or more registration statements with the SEC to register for resale the shares of our common stock issued under the Subscription Agreement, and to use commercially reasonable efforts to cause such registration statement to become effective as soon as practicable.

The description of the Subscription Agreement and the Registration Rights Agreement are not complete and are qualified in their entirety by reference to the Subscription Agreement, which has been filed as an exhibit to our Current Report on Form 8-K, filed on May 17, 2021, and the Registration Rights Agreement, which has been filed as an exhibit to our Current Report on Form 8-K, filed on August 27, 2021. See “Where You Can Find More Information” and “Information Incorporated by Reference.” The representations, warranties and covenants made by us in such agreements were made solely for the benefit of the parties to such agreements, including, in some cases, for the purpose of allocating risk among the parties thereto, and should not be deemed to be a representation, warranty or covenant to you. Moreover, such representations, warranties or covenants were made as of an earlier date. Accordingly, such representations, warranties and covenants should not be relied on as accurately representing the current state of our affairs.

Implications of Being a Smaller Reporting Company and an Emerging Growth Company

We are a “smaller reporting company” as defined in Rule 12b-2 promulgated under the Exchange Act. We may remain a smaller reporting company until we have a non-affiliate public float in excess of $250.0 million and annual revenues in excess of $100.0 million, or a non-affiliate public float in excess of $700.0 million, each as determined on an annual basis. A smaller reporting company may take advantage of relief from some of the reporting requirements and other burdens that are otherwise applicable generally to public companies. To the extent that we take advantage of these reduced burdens, the information that we provide stockholders may be different than you might obtain from other public companies in which you hold equity interests.

3

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) as well as a “smaller reporting company.” We will remain an emerging growth company until the earliest to occur of (1) the last day of the fiscal year in which we have $1.07 billion or more in annual revenue; (2) the date we qualify as a “large accelerated filer,” with at least $700.0 million of equity securities held by non-affiliates; (3) the date on which we have issued, in any three-year period, more than $1.0 billion in non-convertible debt securities; or (4) December 31, 2022.

RISK FACTORS

Investing in our securities involves a high degree of risk. In addition to the risks and uncertainties discussed under “Special Note Regarding Forward-Looking Statements,” you should carefully consider the risks described below, and the risk factors set forth under “Risk Factors” in our definitive proxy statement on Schedule 14A filed July 8, 2021, which is incorporated by reference in this prospectus, together with all other information contained or incorporated by reference in this prospectus, as updated by our subsequent filings under the Exchange Act, and the risk factors and other information contained in any applicable prospectus supplement, before deciding whether to purchase any of the securities being registered pursuant to the registration statement of which this prospectus is a part. If any of these risks actually occur, it may materially harm our business, financial condition, liquidity and results of operations. As a result, the market price of our securities could decline, and you could lose all or part of your investment. The risks and uncertainties we describe in the documents incorporated by reference herein are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently believe are immaterial could materially adversely affect our business, operating results and financial condition, as well as adversely affect the value of an investment in our securities, and the occurrence of any of these risks might cause you to lose all or part of your investment.

Risks Related to this Offering

The number of shares being registered for sale is significant in relation to the number of outstanding shares of our Common Stock.

We have filed a registration statement of which this prospectus is a part to register the shares offered hereunder for sale into the public market by the selling stockholders. Upon registration of the shares of common stock offered hereunder, 10,288,569 shares of the common stock registered hereunder may be resold in the public market immediately without restriction. The remaining 7,340,953 shares of the common stock registered hereunder are currently restricted as a result of lock-up agreements but will be freely tradeable 180 days after August 26, 2021, the closing date of the Merger. These shares represent a large number of shares of our common stock, and if sold in the market all at once or at about the same time, could depress the market price of our common stock during the period the registration statement remains effective and could also affect our ability to raise equity capital.

These shares consist of (i) 5,776,660 shares of common stock issued to certain of the selling stockholders pursuant to the Merger Agreement and (ii) 11,852,862 shares of common stock that were issued to certain selling stockholders in the PIPE Financing.

The table below sets forth, to our knowledge, information concerning the beneficial ownership of shares of our common stock by the selling stockholders as of September 22, 2021. The information in the table below with respect to the selling stockholders has been obtained from the respective selling stockholders. The selling stockholders may sell all, some or none of the shares of common stock subject to this prospectus. See “Plan of Distribution” as may be supplemented and amended from time to time. We do not know how long the selling stockholders will hold the shares before selling them, and except as set forth below under “Relationship with Selling Stockholders,” we currently have no agreements, arrangements or understandings with the selling stockholders regarding the sale or other disposition of any of the shares.

Plan of Distribution

The selling stockholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of common stock or interests in shares of common stock received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein:

• ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

• block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction;

• purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

• an exchange distribution in accordance with the rules of the applicable exchange;

• privately negotiated transactions;

• short sales effected after the date the registration statement of which this prospectus is a part is declared effective by the SEC;

• through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

• broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;

• a combination of any such methods of sale; and

• any other method permitted by applicable law.

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933, as amended (the “Securities Act”), amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling stockholders for purposes of this prospectus.

In connection with the sale of our common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

16

The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of the common stock less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering.

The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act, provided that they meet the criteria and conform to the requirements of that rule, or another available exemption from the registration requirements of the Securities Act.

The selling stockholders and any underwriters, broker-dealers or agents that participate in the sale of the common stock or interests therein may be “underwriters” within the meaning of Section 2(a)(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling stockholders who are “underwriters” within the meaning of Section 2(a)(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act.

To the extent required, the shares of our common stock to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

In order to comply with the securities laws of some states, if applicable, the common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Securities Exchange Act of 1934, as amended, may apply to sales of shares in the market and to the activities of the selling stockholders and their affiliates. In addition, to the extent applicable, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

We have agreed to indemnify the selling stockholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares offered by this prospectus.

We have agreed with the selling stockholders to use commercially reasonable efforts to cause the registration statement of which this prospectus constitutes a part effective and to remain continuously effective until the earlier of (1) such time as all of the shares covered by this prospectus have been disposed of pursuant to and in accordance with such registration statement or (2) (B) the date that all the shares covered by this prospectus cease to be “Registrable Securities” (as defined in the Registration Rights Agreement). Shares will cease to be Registrable Securities under the Registration Rights Agreement upon the earlies to occur of the following: (a) the sale by any person of such shares of common stock either pursuant to a registration statement under the Securities Act or under Rule 144 or 145 (or any similar provision then in effect) (in which case, only such common stock, as applicable, sold shall cease to be Registrable Securities), (b) such shares of common stock shall have been otherwise transferred, new certificates for such shares not bearing a legend restricting further transfer shall have been delivered by Company and subsequent public distribution of such shares shall not require registration under the Securities Act, or (c) such shares of common stock cease to be outstanding.
