To Our Clients:

Enclosed for your consideration are the Offer to Purchase dated June 17, 2022 (the “Offer to Purchase”) and the related Letter of Transmittal (as it may be amended or supplemented from time to time, the “Letter of Transmittal” and, together with the Offer to Purchase, collectively the “Offer”) in connection with the offer by Rhumba Merger Sub Inc., a Delaware corporation (“Purchaser”) and a wholly owned subsidiary of Bristol-Myers Squibb Company, a Delaware corporation (“Parent”), to acquire all of the outstanding shares of common stock, par value $0.0001 per share (the “Shares”), of Turning Point Therapeutics, Inc., a Delaware corporation (“Turning Point”), for $76.00 per Share (the “Offer Price”), in cash, without interest, subject to any applicable withholding of taxes, upon the terms and subject to the conditions set forth in the Offer. Also enclosed is Turning Point’s Solicitation/Recommendation Statement on Schedule 14D-9.

We or our nominees are the holder of record of Shares held for your account. A tender of such Shares can be made only by us or our nominees as the holder of record and pursuant to your instructions. The enclosed Letter of Transmittal is furnished to you for your information only and cannot be used by you to tender Shares held by us or our nominees for your account.

We request instructions as to whether you wish us to tender any or all of the Shares held by us or our nominees for your account, upon the terms and subject to the conditions set forth in the Offer.

Your attention is directed to the following:

1.	The Offer Price is $76.00 per Share, in cash, without interest, subject to any applicable withholding of taxes, upon the terms and subject to the conditions set forth in the Offer.

2.	The Offer is being made for all outstanding Shares.

The Offer is being made pursuant to the Agreement and Plan of Merger, dated as of June 2, 2022 (as it may be amended or supplemented from time to time, the “Merger Agreement”), among Turning Point, Parent and Purchaser. The Merger Agreement provides, among other things, that as promptly as reasonably practicable following (but in any event on the same date as) the acceptance of the Shares for payment (the “Offer Acceptance Time”), subject to the satisfaction or waiver of the other conditions set forth in the Merger Agreement, Purchaser will merge with and into Turning Point (the “Merger”), with Turning Point continuing as the surviving corporation and a wholly owned subsidiary of Parent. At the effective time of

the Merger (being such date and at such time as the certificate of merger in respect of the Merger is duly filed with the Secretary of State of the State of Delaware or at such later time and date as may be agreed upon by the parties to the Merger Agreement in writing and specified in the certificate of merger in accordance with the DGCL, the “Merger Effective Time”), each outstanding Share (other than (i) Shares held by Turning Point or held in Turning Point’s treasury, (ii) Shares held by Parent, Purchaser, or any other direct or indirect wholly owned subsidiary of Parent, (iii) Shares irrevocably accepted for purchase in the Offer and (iv) Shares outstanding immediately prior to the Merger Effective Time that are held by holders who are entitled to appraisal rights under Section 262 of the Delaware General Corporation Law (the “DGCL”) and have properly exercised and perfected their respective demands for appraisal of such Shares in the time and manner provided in Section 262 of the DGCL and, as of the Merger Effective Time, have neither effectively withdrawn nor lost their rights to such appraisal and payment under the DGCL) will be automatically converted into the right to receive the Offer Price, in cash, without interest, subject to any applicable withholding of taxes. No appraisal rights are available in connection with the Offer. However, pursuant to the DGCL, if the Offer is successful and the Merger is consummated, stockholders of Turning Point who (i) did not tender their Shares in the Offer; (ii) follow the procedures set forth in Section 262 of the DGCL; and (iii) do not thereafter withdraw their demand for appraisal of such Shares or otherwise lose their appraisal rights, in each case in accordance with Section 262 of the DGCL, will be entitled to receive appraisal rights for the “fair value” of their Shares in accordance with Section 262 of the DGCL. The “fair value” of such Shares as of the Merger Effective Time could be more than, the same as or less than the consideration to be received pursuant to the Merger. The Merger Agreement is more fully described in Section 13 of the Offer to Purchase.

The board of directors of Turning Point (the “Turning Point Board”), at a meeting duly called and held, unanimously (a) determined that the Merger Agreement and the transactions contemplated by the Merger Agreement, including the Offer and the Merger (the “Transactions”), are advisable to, and in the best interests of, Turning Point and its stockholders, (b) approved the execution, delivery and performance by Turning Point of the Merger Agreement and the consummation by Turning Point of the Transactions, (c) agreed that the Merger Agreement is subject to Section 251(h) of the DGCL, and (d) resolved to recommend that Turning Point’s stockholders tender their Shares pursuant to the Offer.

The Offer and withdrawal rights expire one minute following 11:59 p.m., Eastern Time, on July 18, 2022, unless extended or earlier terminated as permitted by the Merger Agreement (such time or such subsequent time to which the expiration of the Offer is extended in accordance with the Merger Agreement, the “Expiration Time”).

been duly satisfied; (e) (i) any consent, approval or clearance with respect to, or terminations or expiration of any applicable mandatory waiting period (and any extensions thereof) imposed under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the “HSR Act”) will have been received or will have terminated or expired, as the case may be, (ii) there will not be in effect any agreement between Parent, Purchaser or Turning Point and the Federal Trade Commission or the U.S. Department of Justice pursuant to which Parent, Purchaser or Turning Point has agreed not to consummate the Merger for any period of time and (iii) the conditions relating to Antitrust Laws (as defined in the Offer to Purchase) set forth in the disclosure schedule delivered by Turning Point in accordance with the terms of the Merger Agreement will have been met; (f) there not having been issued by any court of competent jurisdiction or remain in effect any judgment, temporary restraining order, preliminary or permanent injunction or other order preventing the acquisition of or payment for Shares pursuant to the Offer or the consummation of the Offer or the Merger nor will any action have been taken, or any applicable law or order promulgated, entered, enforced, enacted, issued or deemed applicable to the Offer or the Merger by any governmental body which directly or indirectly prohibits, or makes illegal, the acquisition of or payment for Shares pursuant to the Offer, or the consummation of the Merger (each of the conditions in this clause (f) and the preceding clause (e) (in the case of this clause (f), as such condition directly relates to the HSR Act, the EU Regulation or any other Antitrust Laws (as defined in the Offer to Purchase) in Germany, the “Regulatory Condition”); (g) since the date of the Merger Agreement, there not having occurred a Material Adverse Effect (as defined in the Merger Agreement) that is continuing (the “MAE Condition”); and (h) the Merger Agreement not having been terminated in accordance with its terms. These conditions to the Offer are described in “The Offer—Section 15—Conditions to the Offer” of the Offer to Purchase.

Any stock transfer taxes applicable to the sale of Shares to the Purchaser pursuant to the Offer will be paid by the Purchaser, except as otherwise set forth in Instruction 6 of the Letter of Transmittal. However, federal income tax backup withholding at a current rate of 24% may be required, unless the required taxpayer identification information is provided and certain certification requirements are met, or unless an exemption is established. See Instruction 8 of the Letter of Transmittal.

If you wish to have us or our nominees tender any or all of your Shares, please complete, sign, detach and return the instruction form below.

In those jurisdictions where the applicable laws require that the Offer be made by a licensed broker or dealer, the Offer will be deemed to be made on behalf of Purchaser by one or more registered brokers or dealers licensed under the laws of such jurisdiction to be designated by Purchaser.
