To Brokers, Dealers, Commercial Banks, Trust Companies and Other Nominees:

We have been engaged by Concentra Merger Sub VI, Inc., a Delaware corporation (“Purchaser”) and a wholly owned subsidiary of Concentra Biosciences, LLC, a Delaware limited liability company (“Parent”), to act as Depositary and Paying Agent in connection with Purchaser’s offer to purchase all of the outstanding shares of common stock, par value $0.0001 per share (the “Shares”), of Elevation Oncology, Inc., a Delaware corporation (“Elevation”), for: (i) $0.36 per Share in cash (the “Cash Amount”); plus (ii) one non-transferable contractual contingent value right for each Share (each, a “CVR,” and each CVR together with the Cash Amount, the “Offer Price”), all upon the terms and subject to the conditions described in the Offer to Purchase (together with any amendments or supplements thereto, the “Offer to Purchase”) and in the related Letter of Transmittal (together with any amendments or supplements thereto, the “Letter of Transmittal” and, together with the Offer to Purchase, the “Offer”) enclosed herewith. Please furnish copies of the enclosed materials to those of your clients for whom you hold Shares registered in your name or in the name of your nominee. On June 8, 2025, the Elevation board of directors (the “Elevation Board”) at a duly called and held meeting, duly and by unanimous vote: (i) determined that the terms of the Merger Agreement, the Offer and the other transactions contemplated by the Merger Agreement and the CVR Agreement (collectively, the “Transactions”) are advisable, fair to, and in the best interests of, Elevation and Elevation’s stockholders; (ii) approved and declared advisable the Merger Agreement and the Transactions; (iii) authorized and approved the execution, delivery and performance by Elevation of the Merger Agreement and the consummation by Elevation of the Transactions; and (iv) resolved to recommend that Elevation’s stockholders accept the Offer and tender their shares of Elevation Common Stock in the Offer.

Concurrently with the execution of the Merger Agreement, and as a condition and inducement to Elevation’s willingness to enter into the Merger Agreement, Tang Capital Partners, LP, a Delaware limited partnership (“TCP” or “Guarantor”) and sole member of Parent, delivered to Elevation a duly executed limited guaranty (the “Limited

Guaranty”), dated as of the date of the Merger Agreement, in favor of Elevation, in respect of certain obligations of Parent and Purchaser under the Merger Agreement and the CVR Agreement. Certain obligations under the Limited Guaranty are subject to a cap of $21,400,000, plus Enforcement Costs, under the Merger Agreement and an amount equivalent to the CVR Proceeds (as defined below), plus Enforcement Costs up to the CVR Expense Cap, under the CVR Agreement. Tang Capital Management, LLC, a Delaware limited liability company (“TCM”), is the sole manager of Parent and the general partner of TCP. Accordingly, TCP and TCM are considered co-offerors in the Offer.

The Offer is not subject to any financing conditions. Certain conditions to the Offer are described in Section 9 of the Offer to Purchase.

For your information and for forwarding to your clients for whom you hold Shares registered in your name or in the name of your nominee, we are enclosing the following documents:
