SELLING STOCKHOLDER

This prospectus relates to the possible sale by Bayer AG, who we refer to as the selling stockholder (which term, as used in this prospectus, includes donees, pledgees, transferees or other successors-in-interest), of up to 1,346,313 shares of our common stock (plus an indeterminate number of shares of our common stock that may be issued upon stock splits, stock dividends or similar transactions, in accordance with Rule 416 under the Securities Act) that were issued to the selling stockholder on July 16, 2019, pursuant to a stock purchase agreement. See “Relationship with Selling Stockholder” below for more information regarding the transactions to which these shares of common stock relate.

The table below sets forth, to our knowledge, information concerning the beneficial ownership of shares of our common stock held by the selling stockholder as of September 15, 2019. The information in the table below with respect to the selling stockholder has been obtained from the selling stockholder. The selling stockholder may sell all, some or none of the shares of common stock subject to this prospectus. See “Plan of Distribution.”

Beneficial ownership is determined in accordance with the rules of the SEC and includes voting or investment power with respect to shares. Unless otherwise indicated below, to our knowledge, the person named in the table has sole voting and investment power with respect to such person’s shares of common stock. The inclusion of any shares in this table does not constitute an admission of beneficial ownership for the person named below. The percentage of beneficial ownership is based upon 33,694,458 shares of common stock outstanding on September 15, 2019.

To our knowledge and except as noted under “Relationship with Selling Stockholder” below, the selling stockholder does not have, and within the past three years has not had, any position, office or other material relationship with us or any of our predecessors or affiliates.

Relationship with Selling Stockholder

Collaboration and License Agreement

On June 3, 2019, we and Bayer AG (which we refer to herein, collectively with its controlled affiliates, as Bayer), directly or through one or more wholly owned subsidiaries, entered into a Collaboration and License Agreement, or the Bayer Collaboration Agreement, setting forth our collaboration to identify or optimize PROTAC targeted protein degraders that mediate for degradation of target proteins, or Targets, using our proprietary platform technology, that are selected by Bayer, subject to certain exclusions and limitations. The Bayer Collaboration Agreement became effective in July 2019 upon the occurrence of the joint venture closing described below.

8

Under the Bayer Collaboration Agreement, we and Bayer will conduct a research program pursuant to separate research plans mutually agreed to by us and Bayer and tailored to each Target selected by Bayer. Bayer may make substitutions for any such initial Target candidates, subject to certain conditions and based on the stage of research for such Target. During the term of the Bayer Collaboration Agreement, we are not permitted, either directly or indirectly, to design, identify, discover or develop any small molecule pharmacologically-active agent whose primary mechanism of action is, by design, directed to the inhibition or degradation of any Target selected or reserved by Bayer, or grant any license, covenant not to sue or other right to any third party in the field of human disease under the licensed intellectual property for the conduct of such activities.

Under the terms of the Bayer Collaboration Agreement, we received an aggregate upfront payment of $17.5 million, plus an additional $1.5 million in research funding payments, in connection with the closing in July 2019. We are entitled to receive up to an additional $10.5 million in research funding payments, subject to potential increases if our costs for research activities exceed the research funding payments allocated to a Target and certain conditions are met. We are also eligible to receive up to $197.5 million in development milestone payments and up to $490.0 million in sales-based milestone payments for all designated Targets. In addition, we are eligible to receive, on net sales of PROTAC targeted protein degrader-related products, mid-single digit to low-double digit tiered royalties, which may be subject to reductions.

Joint Venture

Also on June 3, 2019, we entered into a Commitment Agreement with Bayer, relating to the formation of a joint venture, or the Joint Venture, for the purpose of researching, developing and commercializing PROTAC targeted protein degraders for applications in the field of agriculture, or the JV Entity. We refer to this agreement as the Commitment Agreement. We consummated the formation of the joint venture with Bayer, or the JV Closing, as contemplated by the Commitment Agreement in July 2019, upon the expiration of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, with respect to the reportable transactions and the satisfaction of other applicable closing conditions. Pursuant to the terms of the Commitment Agreement and certain other agreements entered into at the JV Closing, we and Bayer each made an in-kind intellectual property contribution to the JV Entity at the JV Closing. In addition, Bayer has made a $56.0 million total cash commitment to the JV Entity, $16.0 million of which Bayer contributed to the JV Entity in connection with the JV Closing. We and Bayer each hold an ownership interest in the JV Entity initially representing 50% of the ownership interests. A 15% ownership interest of the JV Entity is reserved for the future grant of incentive units to service providers of the JV Entity. The JV Entity will generally be governed by a board of managers, or the JV Board, which will initially be comprised of four voting members, two of which will be designated by us and two of which will be designated by Bayer. JV Board decisions will generally be made by majority vote of the managers, with each manager having one vote. Certain matters will require both our consent and Bayer’s or both of our and Bayer’s designated managers on the JV Board. During the term of the Joint Venture and, in certain limited cases as described below, for one year following the end of the term of the Joint Venture, neither we, Bayer nor any of their respective affiliates may research, develop, manufacture, use or commercialize in the field of agriculture any PROTAC targeted protein degraders whose primary mechanism of action by design is the binding to and degradation of any Target, subject to certain exclusions for early stage research activities and minority investments. The JV Entity and Bayer also entered into an option agreement (which we refer to as the Option Agreement) pursuant to which the parties will agree to certain procedures for, and preferential rights relating to, the possible transfer to Bayer of PROTAC targeted protein degrader product candidates researched, developed and commercialized by the JV Entity under the Joint Venture. In addition, in the event either Bayer or a third party licenses a PROTAC targeted protein degrader candidate from the JV Entity pursuant to the Option Agreement, the non-licensing party or parties to the Commitment Agreement will be prohibited from developing, commercializing or otherwise exploiting any product utilizing PROTAC technology to target the same Target as that of the licensed product candidate in the field of agriculture.

Stock Purchase Agreement

In connection with the execution of the Bayer Collaboration Agreement and the Commitment Agreement, on June 3, 2019, we entered into a stock purchase agreement, or the Stock Purchase Agreement, pursuant to which we issued and sold to Bayer, in a private placement on July 16, 2019, 1,346,313 shares of common stock, or the Shares, at a price of $24.14 per share, for an aggregate purchase price of approximately $32.5 million.

Investor Agreement

In connection with the Stock Purchase Agreement, we entered into an investor agreement with Bayer, dated as of July 16, 2019, or the Investor Agreement, pursuant to which we agreed to provide Bayer with certain registration rights such that, at any time prior to the third anniversary of the execution of the Investor Agreement, if we proposed to register shares of our common stock on a registration statement to be filed with the SEC, Bayer would have the right to require us to use commercially reasonable efforts to prepare and file with the SEC a registration statement covering the resale of the Shares. We agreed to be responsible for all fees and expenses incurred in connection with the registration of the Shares for resale. The Investor Agreement also includes customary indemnification rights in connection with the registration statement. The registration statement of which this prospectus is a part has been filed in accordance with the Investor Agreement.

The foregoing summary descriptions of the Collaboration Agreement, the Commitment Agreement, the Option Agreement, the Stock Purchase Agreement and the Investor Agreement do not purport to be complete and are qualified in their entirety by reference to the full text of such documents, which were filed as exhibits to our Quarterly Report on Form 10-Q, dated August 5, 2019, and are incorporated by reference herein.

PLAN OF DISTRIBUTION

The selling stockholder, which term 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 the 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 stockholder may use any one or more of the following methods when disposing of shares or interests therein:

The selling stockholder 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, amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholder 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 beneficial owners for purposes of this prospectus.

In connection with the sale of common stock or interests therein, the selling stockholder 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 stockholder may also sell shares of 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 stockholder 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).

11

The aggregate proceeds to the selling stockholder 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. The selling stockholder 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.

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(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(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 name of the selling stockholder, 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 stockholder that the anti-manipulation rules of Regulation M promulgated under the Exchange Act may apply to sales of shares in the market and to the activities of the selling stockholder 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 stockholder for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholder 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 stockholder 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 stockholder to keep the registration statement of which this prospectus constitutes a part effective until the earlier of (1) such time as all of the shares covered by this prospectus have been sold and (2) the date on which all of the shares may be sold without restriction pursuant to Rule 144 of the Securities Act.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

The following table sets forth the various expenses to be incurred in connection with the sale and distribution of the securities being registered hereby, all of which will be borne by us (except any underwriting discounts and commissions and expenses incurred by the selling stockholder for brokerage, accounting, tax or legal services or any other expenses incurred by the selling stockholder in disposing of the shares). All amounts shown are estimates except the SEC registration fee.

Section 102 of the Delaware General Corporation Law, or the DGCL, permits a corporation to eliminate the personal liability of its directors or its stockholders for monetary damages for a breach of fiduciary duty as a director, except where the director breached his or her duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit. Our certificate of incorporation provides that no director shall be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duty as a director, notwithstanding any provision of law imposing such liability, except to the extent that the DGCL prohibits the elimination or limitation of liability of directors for breaches of fiduciary duty.

Section 145 of the DGCL provides that a corporation has the power to indemnify a director, officer, employee, or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlements actually and reasonably incurred by the person in connection with an action, suit or proceeding to which he or she is or is threatened to be made a party by reason of such position, if such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful, except that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or other adjudicating court determines that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

Our certificate of incorporation provides that we will indemnify each person who was or is a party or threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of us) by reason of the fact that he or she is or was, or has agreed to become, our director or officer, or is or was serving, or has agreed to serve, at our request as a director, officer, partner, employee or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise (all such persons being referred to as an “Indemnitee”), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding and any appeal therefrom, if such Indemnitee acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, our best interests, and, with respect to any criminal action or proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful. Our certificate

II-1

of incorporation also provides that we will indemnify any Indemnitee who was or is a party to an action or suit by or in the right of us to procure a judgment in our favor by reason of the fact that the Indemnitee is or was, or has agreed to become, our director or officer, or is or was serving, or has agreed to serve, at our request as a director, officer, partner, employee or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise, or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees) and, to the extent permitted by law, amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding, and any appeal therefrom, if the Indemnitee acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, our best interests, except that no indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to us, unless a court determines that, despite such adjudication but in view of all of the circumstances, he or she is entitled to indemnification of such expenses. Notwithstanding the foregoing, to the extent that any Indemnitee has been successful, on the merits or otherwise, he or she will be indemnified by us against all expenses (including attorneys’ fees) actually and reasonably incurred by him or her or on his or her behalf in connection therewith. If we do not assume the defense, expenses must be advanced to an Indemnitee under certain circumstances.

We have entered into indemnification agreements with all of our directors and executive officers. In general, these agreements provide that we will indemnify the director or executive officer to the fullest extent permitted by law for claims arising in his or her capacity as a director or officer of our company or in connection with their service at our request for another corporation or entity. The indemnification agreements also provide for procedures that will apply in the event that a director or executive officer makes a claim for indemnification and establish certain presumptions that are favorable to the director or executive officer.

We maintain a general liability insurance policy which covers certain liabilities of our directors and officers arising out of claims based on acts or omissions in their capacities as directors or officers.

Insofar as the foregoing provisions permit indemnification of directors, executive officers, or persons controlling us for liability arising under the Securities Act of 1933, as amended, or the Securities Act, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Ladies and Gentlemen:

This opinion is furnished to you in connection with a Registration Statement on Form S-3 (the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), for the registration of the resale of an aggregate of 1,346,313 shares of Common Stock, $0.001 par value per share (the “Shares”), of Arvinas, Inc., a Delaware corporation (the “Company”). All of the Shares are being registered on behalf of a certain stockholder of the Company (the “Selling Stockholder”).

We are acting as counsel for the Company in connection with the registration for resale of the Shares. We have examined signed copies of the Registration Statement filed with the Commission. We have also examined and relied upon minutes of meetings of the stockholders and the Board of Directors of the Company as provided to us by the Company, the Certificate of Incorporation and Bylaws of the Company, each as restated and/or amended to date, and such other documents as we have deemed necessary for purposes of rendering the opinions hereinafter set forth.

In our examination of the foregoing documents, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as copies, the authenticity of the originals of such latter documents and the legal competence of all signatories to such documents.

Our opinion below, insofar as it relates to the Shares being fully paid, is based solely on a certificate of the Chief Financial Officer of the Company confirming the Company’s receipt of the consideration called for by the applicable resolutions authorizing the issuance of such Shares.

We assume that the appropriate action will be taken, prior to the offer and sale of the Shares by the Selling Stockholder, to register and qualify the Shares for sale under all applicable state securities or “blue sky” laws.
