pendency of the transaction on Kineta’s or TuHURA’s business relationships, competition, business, financial condition, and operating results; risks that the Mergers disrupt current plans and operations of Kineta or TuHURA and the ability of Kineta or TuHURA to retain and hire key personnel; risks related to diverting either management team’s attention from ongoing business operations of Kineta or TuHURA; the outcome of any legal proceedings that may be instituted against Kineta or TuHURA related to the Merger Agreement or the transaction; the ability of TuHURA to successfully integrate Kineta’s business or fully realize the anticipated synergies or other benefits expected from the Mergers; the ability of TuHURA to implement its plans, forecasts, expected financial performance and other expectations with respect to Kineta’s business or the combined business after the completion of the Mergers and realize additional opportunities, develop customer relationships, additional products and Kineta’s existing business; risks associated with third party contracts containing consent and/or other provisions that may be triggered by the Mergers; the potentially significant amount of any costs, fees, expenses, impairments or charges related to the Mergers; the risk of no amounts being payable under the Disposed Asset Payment Right; the potential dilution of TuHURA and Kineta stockholders’ ownership percentage of TuHURA after the Mergers as compared to their ownership percentage of TuHURA and Kineta, as applicable, prior to the Mergers; TuHURA and Kineta directors and executive officers having interests in the Mergers that are different from, or in addition to, the interests of TuHURA and Kineta stockholders generally; macroeconomic conditions and geopolitical uncertainty in the global economy; uncertainty in the growth of the biopharmaceutical sector; the highly competitive industries TuHURA and Kineta operate in; actions by the U.S. or foreign governments, such as the imposition of additional export restrictions or tariffs; legislative, regulatory and economic developments affecting Kineta’s and TuHURA’s businesses; the evolving legal, regulatory and tax regimes under which Kineta and TuHURA operate; restrictions during the pendency of the Mergers that may impact Kineta’s or TuHURA’s ability to pursue certain business opportunities or strategic transactions, and unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism or outbreak of war or hostilities, as well as Kineta’s and TuHURA’s response to any of the aforementioned factors. The foregoing list of risks, uncertainties and factors is not exhaustive. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements.

You should carefully consider the foregoing factors and the other risks and uncertainties that affect the businesses of TuHURA and Kineta described in the “Risk Factors” section of their respective Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and other documents filed by either of them from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. All forward-looking statements by their nature address matters that involve risks and uncertainties, many of which are beyond TuHURA’s and Kineta’s control, and are not guarantees of future results. Readers are cautioned not to put undue reliance on forward-looking statements, and TuHURA and Kineta assume no obligation and do not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise, unless required by law. Neither TuHURA nor Kineta gives any assurance that either TuHURA or Kineta will achieve its expectations.

(e) If the Stockholders Representative does not properly deliver a Dispute Notice to the Surviving Company prior to the expiration of the Review Period, Parent’s calculation of Closing Liabilities and Debt, Closing Net Working Capital Amount and Unpaid Company Transaction Expenses set forth in the Closing Date Schedule shall be deemed final and binding on Parent, the Surviving Company, the Stockholders Representative and the stockholders of the Company immediately prior to the Effective Time for all purposes of this Agreement.

(f) If the Stockholders Representative delivers a Dispute Notice to Parent prior to the expiration of the Review Period, then the Stockholders Representative and Parent shall negotiate in good faith to reach agreement on Closing Liabilities and Debt, Closing Net Working Capital Amount and Unpaid Company Transaction Expenses.

No interest will be paid or accrued for the benefit of holders of Certificates or Book-Entry Shares on the Merger Consideration.

(c) If payment of the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition of payment that such Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and shall be properly transferred, and that the Person requesting such payment shall have paid any transfer and other Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of such Certificate or shall have established to the satisfaction of Parent that such Tax either has been paid or is not applicable.

If for any reason (including investment losses) the cash in the Exchange Fund is insufficient to fully satisfy all of the payment obligations to be made in cash by the Exchange Agent hereunder (but subject to Section 2.7), Parent shall promptly deposit cash into the Exchange Fund in an amount which is equal to the deficiency in the amount of cash required to fully satisfy such cash payment obligations. Any interest and other income resulting from such investments shall be the property of, and shall be payable to, Parent.

(g) At any time following the date that is twelve (12) months after the Effective Time, Parent shall be entitled to require the Exchange Agent to deliver to it or its designee any funds (including any interest received with respect thereto) which have been made available to the Exchange Agent and which have not been disbursed to holders of Certificates, and thereafter such holders shall be entitled to look to Parent and the Surviving Company (subject to abandoned property, escheat or other similar laws) only as general creditors thereof with respect to the Merger Consideration payable upon due surrender of their Certificate. Parent shall, or shall cause the Surviving Company to, pay all charges and expenses, including those of the Exchange Agent, in connection with the exchange of Shares for the Merger Consideration. None of Parent, the Surviving Company, the Exchange Agent or any other Person shall be liable to any Person in respect of any portion of the Exchange Fund properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(h) If any Certificate shall have been lost, stolen or destroyed, upon the holder’s compliance with the replacement requirements established by the Exchange Agent, including, if reasonably required by the Surviving Company, the posting by such Person of a bond in customary amount as indemnity against any claim that may be made against it or the Surviving Company with respect to such Certificate, the Exchange Agent will deliver in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect thereof pursuant to this Agreement.

(i) Notwithstanding anything to the contrary in this Agreement, no holder of uncertificated Shares held through the Depository Trust Company will be required to provide a Certificate or an executed letter of transmittal to the Exchange Agent in order to receive the payment that such holder is entitled to receive pursuant to Section 2.1(a).

(j) The stock transfer books of the Company shall be closed immediately upon the Effective Time, and there shall be no further registration of transfers of Shares thereafter on the records of the Company. At or after the Effective Time, the Certificates or Book-Entry Shares shall, subject to compliance with the provisions of this Article II by the holder thereof and subject to Section 2.7, represent only the right to receive the Merger Consideration with respect to the Shares formerly represented thereby.

10

(k) Notwithstanding any other provision of this Agreement, no fractional shares of Parent Common Stock will be issued and any holder of Shares entitled to receive a fractional share of Parent Common Stock but for this Section 2.6(k) shall be entitled to receive a cash payment in lieu thereof, which payment shall be calculated by the Exchange Agent and shall represent such holder’s proportionate interest in a share of Parent Common Stock based on the Parent Share Value.

Section 2.7 Dissenting Shares.

If any such holder fails to perfect or withdraws or loses any such right to appraisal, each such Share of such holder shall thereupon be converted into and become exchangeable only for the right to receive, as of the later of the Effective Time and the time that such right to appraisal has been irrevocably lost, withdrawn or expired, the Merger Consideration in accordance with Section 2.1(a). The Company shall serve prompt notice to Parent of any demands received by the Company for appraisal of any Shares, and, prior to the Effective Time, Parent shall have the right to participate in any negotiations and proceedings with respect to any such demands and, for the avoidance of doubt, control the negotiations and proceedings after the Effective Time.

(c) Subject to the permitted actions contemplated by Section 7.1(d)(ii), neither the Company Board nor any committee thereof shall (i) withhold, withdraw, modify or qualify, or propose publicly to withhold, withdraw, modify or qualify, the Recommendation, in each case, in a manner adverse to Parent, Merger Sub I or Merger Sub II, (ii) except as permitted by this Section 5.4, fail to include the Recommendation in the Proxy Statement/Prospectus, (iii) if a tender or exchange offer for shares of capital stock of the Company that constitutes an Acquisition Proposal is commenced, fail to recommend against acceptance of such tender or exchange offer by the stockholders of the Company (including by taking no position with respect to the acceptance of such tender or exchange offer by the stockholders of the Company) within five (5) Business Days after commencement thereof pursuant to Rule 14d-2 under the Exchange Act or (iv) approve, authorize or recommend or otherwise declare advisable, or propose publicly to approve, authorize or recommend or otherwise publicly declare advisable, any Acquisition Proposal or Company Acquisition Agreement (any of such actions, an “Adverse Recommendation Change”). Notwithstanding anything to the contrary in this Section 5.4, at any time prior to, but not after obtaining the Company Stockholder Approval, the Company Board may effect an Adverse Recommendation Change with respect to an Acquisition Proposal if, and only if, (A) such Acquisition Proposal was not solicited by the Company or caused by the Company to have been solicited, in each case, following the date of this Agreement in violation of Section 5.4, (B) the Company provides Parent with a written notice indicating that the Company, acting in good faith, believes that such Acquisition Proposal constitutes a Superior Proposal and, therefore, plans to conduct a meeting of the Company Board for the purpose of considering whether such Acquisition Proposal constitutes a Superior Proposal, which notice shall be delivered to Parent at least five (5) Business Days prior to the date of such meeting of the Company Board and shall also include a copy of such Acquisition Proposal (or, if made orally, a reasonable description of the material terms of such Acquisition Proposal) and the other information required by Section 5.4(d), (C) during such five (5) Business Day period the Company shall, and shall cause its Representatives to, negotiate with Parent in good faith (to the extent Parent desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Acquisition Proposal shall cease to constitute a Superior Proposal, (D) the Company Board makes the determination that such Acquisition Proposal (after taking into account any adjustment to the terms and conditions of this Agreement proposed by Parent in response to such proposal) constitutes a Superior Proposal and (E) the Company Board concludes in good faith, after consultation with outside legal counsel, based on the information then available that failing to make an Adverse Recommendation Change would violate its fiduciary duties to the Company’s stockholders under applicable Laws. Upon any amendment to the financial terms or any other material amendment of an Acquisition Proposal, the Company shall promptly (and in any event within twenty-four (24) hours) provide a new notice to Parent describing such amendment and the obligations set forth in clauses (C) and (D) of this Section 5.4(c) shall continue for at least two (2) Business Days after delivery to Parent of such notice (and, if necessary, the Company Board meeting shall be postponed to accommodate such additional negotiation period).

(d) The Company promptly (and in any event within twenty-four (24) hours) shall advise Parent orally and in writing of (i) any written Acquisition Proposal, (ii) any written request for non-public information relating to the Company or its Subsidiaries, other than requests for information not reasonably expected to be related to an Acquisition Proposal and (iii) any written inquiry or request for discussion or negotiation regarding an Acquisition Proposal, including, in each case, the identity of the Person making any such Acquisition Proposal, inquiry or request and a copy of any such Acquisition Proposal, inquiry or request (or, if made orally, a reasonable description of the material terms of any such Acquisition Proposal, inquiry or request).

46

(e) Nothing set forth in this Agreement shall prevent the Company or the Company Board from (i) taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a) and Rule 14d-9 promulgated under the Exchange Act (or any similar communication to shareholders in connection with the making or amendment of a tender offer or exchange offer) or from (ii) making any disclosure to the Company’s stockholders if, in the good faith judgment of the Company Board, after consultation with outside legal counsel and based on the information then available, failure to disclose such information would violate its obligations under applicable Law; provided, that any disclosure permitted under this Section 5.4(e) shall be deemed, subject to the last sentence of this Section 5.4(e), an Adverse Recommendation Change unless it includes either an express rejection of the Acquisition Proposal or an express reaffirmation of the Recommendation. A “stop, look and listen” or similar public communication contemplated by Rule 14d-9(f) shall not be deemed to be an Adverse Recommendation Change for purposes of this Agreement.

(f) As used in this Agreement:

(i) “Acquisition Proposal” means any inquiry, proposal or offer from any Person or group of Persons other than Parent or one of its Subsidiaries for (A) a merger, reorganization, consolidation, tender offer, exchange offer, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving an acquisition of the Company or any Subsidiary or Subsidiaries of the Company whose business constitutes 20% or more of the net revenues, net income or assets of the Company and its Subsidiaries, taken as a whole (for the twelve (12)-month period ending on the last day of the Company’s most recently completed fiscal quarter) or (B) the acquisition in any manner, directly or indirectly, of over 20% of the equity securities or consolidated total assets of the Company and its Subsidiaries, in each case other than the Mergers and the other transactions contemplated by this Agreement, other than any inquiry, proposal or offer relating to a Permitted Asset Disposition.

(ii) “Superior Proposal” means any bona fide, written Acquisition Proposal that the Company did not solicit or cause to be solicited following the date of this Agreement in violation of this Section 5.4 (A) on terms which the Company Board determines in good faith, after consultation with the Company’s outside legal counsel and financial advisors, to be more favorable from a financial point of view to the holders of Shares than the Mergers and the other transactions contemplated by this Agreement (including any adjustment to the terms and conditions proposed by Parent in response to such proposal), taking into account all the terms and conditions of the Acquisition Proposal and all legal, financial, regulatory and other aspects of the Acquisition Proposal and the Person making the proposal and (B) that the Company Board believes is reasonably likely to be completed in accordance with its terms, taking into account all financial, regulatory, legal and other aspects of such proposal; provided, that for purposes of the definition of “Superior Proposal,” the references to “20%” in the definition of Acquisition Proposal shall be deemed to be references to “50%.”

47

Section 5.5 Access to Information; Confidentiality.

(a) From the date hereof to the Effective Time or the earlier termination of this Agreement, upon reasonable prior written notice, the Company shall, and shall use its reasonable best efforts to cause its Subsidiaries, officers, directors and Representatives to, afford to Parent and its Representatives reasonable access during normal business hours and upon reasonable advance notice, consistent with applicable Law, to its officers, employees, properties, offices, other facilities and books and records, and shall furnish Parent and its Representatives with all existing financial, operating and other data and information as Parent shall reasonably request in writing in order to consummate the Mergers; provided, that, Parent and its Representatives shall conduct any such activities in such a manner as to not interfere unreasonably with the business or operations of the Company. All requests for such information pursuant to this Section 5.5 shall be made through the Chief Financial Officer of the Company or such Person as he shall delegate. Notwithstanding the foregoing, any such investigation or consultation shall be conducted in such a manner as not to interfere unreasonably with the business or operations of the Company or its Subsidiaries or otherwise result in any significant interference with the prompt and timely discharge by the employees of the Company or its Subsidiaries of their normal duties. Neither the Company nor any of its Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would (i) breach any agreement with any third-party, (ii) constitute a waiver of or jeopardize the attorney-client or other legal privilege held by the Company or (iii) otherwise would reasonably be expected to violate any applicable Law; provided, however, that the Company shall provide notice to Parent of the fact that it is withholding access to information pursuant to clause (i), (ii) or (iii) of this Section 5.5(a) and use commercially reasonable efforts to cause such information to be made available in a manner that would not reasonably be expected to cause such breach, waiver or violation.

(b) Each of Parent, Merger Sub I and Merger Sub II will hold and treat and will cause its Representatives to hold and treat in confidence all documents and information concerning the Company and its Subsidiaries furnished to Parent, Merger Sub I or Merger Sub II in connection with the transactions contemplated by this Agreement in accordance with the Mutual Non-Disclosure Agreement, dated March 8, 2024, by and between Parent and the Company (the “Non-Disclosure Agreement”), which the parties agree will remain in full force and effect until the earlier of the Effective Time or the termination of this Agreement in accordance with its terms.

48

Section 5.6 Further Action; Efforts. The parties shall use reasonable best efforts to promptly take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties hereto in doing, all things necessary, proper or advisable to consummate the transactions contemplated by this Agreement. Without limiting the generality of the foregoing, each party: (i) shall make all necessary filings, registrations, declaration and other submissions (if any) and give all notices (if any) required to be made and given by such party in connection with the transactions contemplated by this Agreement, (ii) shall use reasonable best efforts to obtain all necessary and advisable actions or non-actions, waivers and consents, (if any) (pursuant to any applicable Law or Contract, or otherwise) by such party in connection with the transactions contemplated by this Agreement or for such Contract to remain in full force and effect, (iii) shall use reasonable best efforts to lift any injunction prohibiting, or any other legal bar to, the transactions contemplated by this Agreement and (iv) shall use reasonable best efforts to satisfy the conditions precedent to the consummation of the transactions contemplated by this Agreement.

Section 5.7 Registration Statement; Proxy Statement.

(a) As promptly as reasonably practicable after the date of this Agreement, (i) Parent and the Company shall prepare and file with the SEC a joint proxy statement to be sent to the holders of Shares relating to the Company Stockholders Meeting and the holders of shares of Parent Common Stock relating to the Parent Stockholders Meeting (as amended or supplemented from time to time, the “Proxy Statement/Prospectus”), and Parent shall prepare and file with the SEC a Registration Statement on Form S-4 (as amended or supplemented from time to time, the “Registration Statement”) with the Proxy Statement/Prospectus constituting a part thereof, in connection with the issuance of shares of Parent Common Stock constituting the Company Initial Share Consideration and the Company Delayed Share Consideration (the “Parent Share Issuance”). Parent and the Company each shall use its reasonable best efforts to (i) have the Registration Statement declared effective under the Securities Act as promptly as reasonably practicable after such filing, (ii) clear the preliminary Proxy Statement/Prospectus with the SEC as promptly as reasonably practicable after the filing thereof, (iii) mail the definitive Proxy Statement/Prospectus to the holders of Shares and shares of Parent Common Stock as promptly as reasonably practicable after the Registration Statement has been declared effective under the Securities Act and (iv) maintain the effectiveness of the Registration Statement for as long as necessary to consummate the transactions contemplated by this Agreement.

(b) The Company and Parent each agrees, as to itself and its Subsidiaries, that none of the information supplied or to be supplied by it or its Subsidiaries for inclusion or incorporation by reference in (i) the Registration Statement will, at the time the Registration Statement becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading and (ii) the Proxy Statement/Prospectus and any amendment or supplement thereto will, at the date of mailing to holders of Shares and shares of Parent Common Stock and at the time of each of the Company Stockholders Meeting and the Parent Stockholders Meeting, or any adjournment or postponement thereof, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. Notwithstanding the foregoing, (A) the Company assumes no

49

responsibility with respect to information supplied in writing by or on behalf of Parent, Merger Sub I or Merger Sub II for inclusion or incorporation by reference in the Registration Statement or the Proxy Statement/Prospectus and (B) Parent assumes no responsibility with respect to information supplied in writing by or on behalf of the Company for inclusion or incorporation by reference in the Registration Statement or the Proxy Statement/Prospectus. The Company and Parent each agrees that all documents that each is responsible for filing with the SEC in connection with the Mergers or the other transactions contemplated by this Agreement will comply as to form in all material respects with the applicable provisions of the Securities Act and the Exchange Act, and the rules and regulations thereunder.

(c) The Company, Parent and the Merger Subs shall cooperate with each other in the preparation of the Registration Statement and the Proxy Statement/Prospectus. Each of Parent, Merger Sub I, Merger Sub II and the Company and their respective counsels shall (i) be given a reasonable opportunity to review and comment upon the Proxy Statement/Prospectus, the Registration Statement, and any other documents related to the Company Stockholders Meeting, the Parent Stockholders Meeting or the Parent Share Issuance, prior to mailing or the filing thereof with the SEC, as applicable, (ii) provide any comments thereon as promptly as reasonably practicable and (iii) consider such comments in good faith in connection with any such document. Parent shall promptly notify the Company and its counsel of the time when the Registration Statement has become effective and of the issuance of any stop order or suspension of the qualification of the shares of Parent Common Stock issuable in the Mergers for offering or sale in any jurisdiction. Further, each party shall promptly notify the other parties and their counsel of the receipt of any written comments or other material communications such party or its counsel receives from time to time from the SEC or its staff with respect to the Registration Statement or the Proxy Statement/Prospectus and shall provide the other party with copies of any written responses to and telephonic notification of any material oral responses received from the SEC or its staff by such party or its counsel with respect to the Registration Statement or the Proxy Statement/Prospectus. If, at any time prior to the time the Company Stockholder Approval or the Parent Stockholder Approval is obtained, any party shall become aware of the occurrence of any event or other circumstance that requires an amendment or supplement to the Registration Statement or the Proxy Statement/Prospectus so that the Registration Statement or the Proxy Statement/Prospectus, as applicable, does not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, then such party shall notify the other party as promptly as reasonably practicable thereafter, and Parent and the Company each shall use its reasonable best efforts to, as promptly as reasonably practicable thereafter, (A) prepare and file with the SEC such amendment or supplement and (B) mail such amendment or supplement to the holders of Shares and shares of Parent Common Stock, in each case, to the extent legally required.

(d) As promptly as reasonably practicable after the SEC advises that it has no further comments to the Proxy Statement/Prospectus and the Registration Statement is declared effective, the Company shall duly call, give notice of, convene and hold a special meeting of the holders of Shares (the “Company Stockholders Meeting”) to consider and vote upon the adoption of this Agreement, including the Mergers. Subject to Section 5.4, the Company Board shall include the Recommendation in the Proxy Statement/Prospectus and, unless there has been an Adverse Change Recommendation permitted by and in accordance with Section 5.4, shall use

50

reasonable best efforts to solicit adoption of this Agreement by the holders of Shares and take all other actions necessary or advisable to secure the vote or consent of the holders of Shares required by applicable Law to obtain such approval. The Company shall keep Parent updated with respect to proxy solicitation results as reasonably requested by Parent. Once the Company Stockholders Meeting has been called and noticed, the Company shall not postpone or adjourn the Company Stockholders Meeting without the prior written consent of Parent, other than: (i) if as of the time for which the Company Stockholders Meeting is originally scheduled (as set forth in the Proxy Statement/Prospectus), the Company believes in good faith that there are insufficient Shares represented (either in person or by proxy) and voting to obtain the Company Stockholder Approval or to constitute a quorum necessary to conduct the business of the Company Stockholders Meeting, (ii) to ensure that any required supplement or amendment to the Proxy Statement/Prospectus is provided to holders of Shares within a reasonable amount of time in advance of the Company Stockholders Meeting or (iii) as reasonably determined by the Company to comply with applicable Law. The Company shall use its reasonable best efforts to cooperate with Parent to hold the Company Stockholders Meeting on the same day and at the same time as the Parent Stockholders Meeting as soon as reasonably practicable after the date of this Agreement and to set the same record date for each such meeting. If the Company Board makes an Adverse Change Recommendation, it will not alter the obligation of the Company to submit this Agreement to the holders of Shares at the Company Stockholders Meeting to consider and vote upon the adoption of this Agreement, unless this Agreement shall have been terminated in accordance with its terms prior to the Company Stockholders Meeting.

(e) As promptly as reasonably practicable after the SEC advises that it has no further comments to the Proxy Statement/Prospectus and the Registration Statement is declared effective, Parent shall duly call, give notice of, convene and hold a special meeting of holders of shares of Parent Common Stock (the “Parent Stockholders Meeting”) to consider and vote upon (A) an increase in the number of authorized shares of Parent Common Stock to 200 million shares of Parent Common Stock (the “Authorized Share Increase”) and (B) if required by applicable Law, the Parent Share Issuance. Parent shall use its reasonable best efforts to solicit approval of the Authorized Share Increase and, if necessary to comply with applicable Law, the Parent Share Issuance by the holders of shares of Parent Common Stock and take all other actions necessary or advisable to secure the vote or consent of the holders of shares of Parent Common Stock required by applicable Law to obtain such approval. Parent shall keep the Company updated with respect to proxy solicitation results as reasonably requested by the Company. Once the Parent Stockholders Meeting has been called and noticed, Parent shall not postpone or adjourn the Parent Stockholders Meeting without the prior written consent of the Company, other than: (i) if as of the time for which the Parent Stockholders Meeting is originally scheduled (as set forth in the Proxy Statement/Prospectus), Parent believes in good faith that there are insufficient shares of Parent Common Stock represented (either in person or by proxy) and voting to approve the Authorized Share Increase and, if necessary to comply with applicable Law, the Parent Share Issuance or to constitute a quorum necessary to conduct the business of the Parent Stockholders Meeting, (ii) to ensure that any required supplement or amendment to the Proxy Statement/Prospectus is provided to holders of shares of Parent Common Stock within a reasonable amount of time in advance of the Parent Stockholders Meeting or (iii) as reasonably determined by Parent to comply with applicable Law. Parent shall use its reasonable best efforts to cooperate with the Company to hold the Parent Stockholders Meeting on the same day and at the same time as the Company Stockholders Meeting and to set the same record date for each such meeting.

51

Section 5.8 Takeover Laws. If any Takeover Law is or becomes applicable to this Agreement, the Mergers or any of the other transactions contemplated hereby, each of the Company and Parent and their respective board of directors shall use their respective reasonable best efforts to ensure that the Mergers and the other transactions contemplated hereby may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to eliminate or minimize the effect of such Takeover Law with respect to this Agreement, the Mergers and the other transactions contemplated hereby.

Section 5.9 Notification of Certain Matters. The Company and Parent shall promptly notify each other of (a)(i) any notice or other communication received by a party to this Agreement from any Governmental Entity in connection with the Mergers or the other transactions contemplated hereby or (ii) any notice or other communication received by a party to this Agreement from any Person alleging that the consent of such Person is or may be required in connection with the Mergers or the other transactions contemplated hereby if, in the case of this clause (ii), the subject matter or result of such communication would reasonably be expected to be material to the Company or the Mergers or the other transactions contemplated hereby, (b) any Action commenced or, to such party’s knowledge, threatened against, relating to or involving or otherwise affecting such party or any of its Subsidiaries which relate to the Mergers or the other transactions contemplated hereby or (c) the discovery of any fact or circumstance that, or the occurrence or non-occurrence of any event the occurrence or non-occurrence of which, would cause or result in any of the conditions to the Mergers set forth in Article VI not being satisfied or satisfaction of those conditions being materially delayed in violation of any provision of this Agreement; provided, however, that the delivery of any notice pursuant to this Section 5.9 shall not (i) cure any breach of, or non-compliance with, any other provision of this Agreement or (ii) limit the remedies available to the party receiving such notice; provided, further, that failure to give prompt notice pursuant to clause (c) shall not constitute a failure of a condition to the Mergers set forth in Article VI except to the extent that the underlying fact or circumstance not so notified would standing alone constitute such a failure.

Section 5.10 Indemnification, Exculpation and Insurance.

(a) Without limiting any additional rights that any employee may have under any agreement or Company Plan, from the Effective Time through the sixth (6^th) anniversary of the date on which the Effective Time occurs, Parent shall, or shall cause the Surviving Company to, indemnify and hold harmless each present (as of the Effective Time) and former officer, director or employee of the Company and its Subsidiaries (the “Indemnified Parties”), against all claims, losses, liabilities, damages, judgments, inquiries, fines and reasonable fees, costs and expenses, including reasonable attorneys’ fees and disbursements (collectively, “Costs”), incurred in connection with any Action, whether civil, criminal, administrative or investigative, arising out of or pertaining to (i) the fact that the Indemnified Party is or was an officer, director or employee of the Company or any of its Subsidiaries or (ii) matters existing or occurring at or prior to the Effective Time (including this Agreement and the transactions and actions contemplated hereby), whether asserted or claimed prior to, at or after the Effective Time, in each case, to the fullest extent and in the manner permitted by the DGCL and the Company

52

Charter and Company Bylaws as at the date hereof. In the event of any such Action, (A) each Indemnified Party shall be entitled to advancement of expenses incurred in the defense of any Action from Parent or the Surviving Company to the fullest extent and in the manner permitted by the DGCL and the Company Charter and Company Bylaws as at the date hereof; provided, that any Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Person is not entitled to indemnification, (B) neither Parent nor the Surviving Company shall settle, compromise or consent to the entry of any judgment in any proceeding or threatened action, suit, proceeding, investigation or claim (and in which indemnification could be sought by such Indemnified Party hereunder), unless such settlement, compromise or consent includes an unconditional release of such Indemnified Party from all liability arising out of such action, suit, proceeding, investigation or claim or such Indemnified Party otherwise consents, and (C) the Surviving Company shall cooperate in the defense of any such matter.

(b) Except as may be required by applicable Law, Parent and the Company agree that all rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time and rights to advancement of expenses relating thereto now existing in favor of any Indemnified Party as provided in the certificate of incorporation or bylaws (or comparable organizational documents) of the Company and its Subsidiaries or in any indemnification agreement between such Indemnified Party and the Company or any of its Subsidiaries shall survive the Mergers and continue in full force and effect until the expiration of the applicable statute of limitations with respect to any claims against such directors or officers arising out of such acts or omissions, except as otherwise required by applicable Law, and shall not be amended, repealed or otherwise modified in any manner that would adversely affect any right thereunder of any such Indemnified Party.

(c) For a period of six (6) years from the Effective Time, Parent shall either cause to be maintained in effect the current policies of directors’ and officers’ liability insurance and fiduciary liability insurance maintained by the Company and its Subsidiaries or cause to be provided substitute policies or purchase or cause the Surviving Company to purchase, a “tail policy,” in either case of at least the same coverage and amounts containing terms and conditions that are not less advantageous in the aggregate than such policy with respect to matters arising on or before the Effective Time; provided, however, that after the Effective Time, Parent shall not be required to pay with respect to such insurance policies in respect of any one policy year annual premiums in excess of 300% of the last annual premium paid by the Company prior to the date hereof in respect of the coverage required to be obtained pursuant hereto, but in such case shall purchase as much coverage as reasonably practicable for such amount; provided further, that if the Surviving Company purchases a “tail policy” and the coverage thereunder costs more than 300% (per coverage year) of such last annual premium, the Surviving Company shall purchase the maximum amount of coverage that can be obtained for 300% (per coverage year) of such last annual premium. At the Company’s option, the Company may purchase, prior to the Effective Time, a six (6)-year prepaid “tail policy” on terms and conditions (in both amount and scope) providing substantially equivalent benefits as the current policies of directors’ and officers’ liability insurance and fiduciary liability insurance maintained by the Company and its Subsidiaries with respect to matters arising on or before the Effective Time, covering without limitation the transactions contemplated hereby. If such tail prepaid policy has been obtained by the Company prior to the Effective Time, then (i) Parent shall not be required to purchase or cause to be purchased any substitute policy or “tail policy,” and (b) Parent shall cause such policy to be paid and maintained in full force and effect, for its full term, and cause all obligations thereunder to be honored by the Surviving Company and any successor thereof.

53

(d) Notwithstanding anything herein to the contrary, if any Action (whether arising before, at or after the Effective Time) is instituted against any Indemnified Party on or prior to the sixth (6^th) anniversary of the Effective Time, the provisions of this Section 5.10 shall continue in effect until the final disposition of such Action.

(e) The indemnification provided for herein shall not be deemed exclusive of any other rights to which an Indemnified Party is entitled, whether pursuant to Law, Contract or otherwise. The provisions of this Section 5.10 shall survive the consummation of the Mergers and, notwithstanding any other provision of this Agreement that may be to the contrary, expressly are intended to benefit, and shall be enforceable by, each of the Indemnified Parties and their respective heirs and legal representatives.

(f) In the event that the Surviving Company, Parent, or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or a majority of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Company or Parent, as the case may be, shall succeed to the obligations set forth in this Section 5.10.

Section 5.11 Public Announcements. Each of Parent, Merger Sub I and Merger Sub II, on the one hand, and the Company, on the other hand, shall, to the extent reasonably practicable, consult with each other before issuing, and give each other a reasonable opportunity to review and comment upon and consider in good faith all reasonable additions, deletions or chances suggested by the other party, any press release or other public statements with respect to this Agreement, the Mergers and the other transactions contemplated hereby and shall not issue any such press release or make any public announcement prior to such consultation and review, except as may be required by applicable Law, court process or by obligations pursuant to any listing agreement with any national securities exchange or national securities quotation system; provided, however, that the restrictions set forth in this Section 5.11 shall not apply to any release or announcement made or proposed to be made (i) following a determination by the Company Board that an Acquisition Proposal constitutes a Superior Proposal or (ii) following an Adverse Recommendation Change. Parent and the Company agree that the press release announcing the execution and delivery of this Agreement shall be a joint release of Parent and the Company.

Section 5.12 Section 16 Matters. Prior to the Effective Time, the Company Board shall take all such steps as may be necessary or appropriate to cause the transactions contemplated by this Agreement, including any dispositions of Shares (including derivative securities with respect to such Shares) and Company Stock Options (including the acquisition of shares underlying such Company Stock Options or the disposition of such shares) resulting from the transactions contemplated by this Agreement by each individual who is or will be subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company, to be exempt under Rule 16b-3 promulgated under the Exchange Act.

54

Section 5.13 Listing of Parent Common Stock. Parent shall use its reasonable best efforts to cause the shares of Parent Common Stock to be issued in the Mergers to be approved for listing on Nasdaq (subject to official notice of issuance).

Section 5.14 Deregistration. Prior to the Closing Date, the Company shall cooperate with Parent and use reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under applicable Laws to enable the deregistration of the Shares under the Exchange Act and the withdrawal of any active registration statements under the Securities Act as promptly as practicable after the Effective Time; provided, however, that such deregistration and termination shall not be effective until after the Effective Time as of the Closing Date.

Section 5.15 Obligations of the Merger Subs. Parent shall take all actions necessary to cause Merger Sub I, Merger Sub II and the Surviving Company to perform their respective obligations under this Agreement.

Section 5.16 Stockholder Litigation. Subject to any fiduciary duties of the Company Board or the board of directors (or similar governing body) of any of the Company’s Subsidiaries, the Company shall consult with Parent, to the extent legally permissible, in the Company’s defense or settlement of any stockholder litigation (other than any litigation or settlement where the interests of the Company or any of its Affiliates are, or would reasonably be expected to be, adverse to those of Parent, Merger Sub I or Merger Sub II or any of their respective Affiliates) against the Company and/or any of its directors or officers (in their respective capacities as such) relating to the transactions contemplated by this Agreement, provided that the Company shall not settle, compromise or enter into an agreement (other than any settlement, compromise or agreement solely for monetary damages paid entirely from proceeds of insurance, except for any applicable deductible) regarding any settlement or compromise of any stockholder litigation relating to the transactions contemplated by this Agreement requiring the payment of any amount, acceptance of any liability, or the admission of any violations of Law by the Company or its Subsidiaries, in each case, without the prior written consent of Parent (which consent shall not be unreasonably withheld, conditioned or delayed).

Section 5.17 Company Stock Plans. Prior to the Effective Time, the Company shall adopt resolutions so that any Company Stock Plan, and all Company Stock Options, shall terminate, and all rights under any provision of any other plan, program or arrangement providing for the issuance or grant of any other interest with respect to the capital stock or other voting securities of the Company, or for the issuance or grant of any right of any kind, contingent or accrued, to receive benefits measured by the value of a number of Shares shall be canceled effective as of the Effective Time, without any prospective liability on the part of the Company, the Surviving Company, or Parent (except as otherwise contemplated by this Agreement).

Section 5.18 Tax Treatment of Mergers.

(a) Each of the parties to this Agreement intend and do, by executing this Agreement, adopt a plan of reorganization within the meaning of Section 1.368-2(g) of the Treasury Regulations and Section 354(a)(1) of the Code, and that, for U.S. federal income tax purposes, the Mergers, taken together, constitute an integrated plan described in Rev. Rul. 2001-

55

Parent and the Company shall not take any action prior to the Closing, and Parent (and its Affiliates) shall not take any action or fail to take any action (and shall prevent the Surviving Company from taking any action or failing to take any action) following the Closing, that would cause the Mergers to fail to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. Parent, the Company and the Surviving Company (and each of their respective Affiliates, as applicable) shall report the Mergers for income tax purposes as a “reorganization” within the meaning of Section 368(a) of the Code, including the filing of the statement required by Treasury Regulations Section 1.368-3, unless otherwise required by a Tax authority pursuant to a “determination” within the meaning of Section 1313(a) of the Code. Notwithstanding this paragraph and/or any other provision of this Agreement, no party makes any representation with respect to the tax treatment of the Mergers.

(b) The parties hereto intend to comply with Revenue Procedure 2018-12, 2018-6 IRB 349 (“Rev. Proc. 2018-12”), and therefore acknowledge and agree that for purposes of determining the value of the Parent Common Stock to be received by holders of Company capital stock pursuant to the transactions contemplated by this Agreement: (i) the “Safe Harbor Valuation Method” (within the meaning of Section 4.01(1) of Rev. Proc. 2018-12) will be the average of the daily volume weighted average prices as described in Section 4.01(1) of Rev.

CREDIT FACILITIES

Section 2.1 Advances. On each Advance Date, subject to the terms and conditions hereof, Lender agrees to lend to Borrower term loans not to exceed (x) on each Advance Date, the Advance Cap and (y) in the aggregate for all term loans hereunder (including, for the avoidance of doubt, the Existing Advances), the Funding Cap. Each Existing Advance and each other advance hereunder from time to time (each an “Advance” and, collectively, the “Advances”) shall be evidenced by a single promissory note substantially in the form of Exhibit B attached hereto (the “Note”). Subject to the satisfaction of the conditions precedent set forth herein, the disbursement of each Advance hereunder on and after the Effective Date shall be made upon written notice received by Lender not later than three (3) Business Days prior to the requested Advance Date specifying the Advance Date, the amount of such Advance, the third-party provider to whom such Advance will be disbursed on behalf of Borrower, and the account of such third-party provider to which such Advance is to be disbursed, together with such supporting documentation as Lender may reasonably request. Amounts borrowed hereunder and repaid or prepaid may not be reborrowed. Notwithstanding the foregoing, the Funding Cap may be increased by the mutual written consent of Borrower and Lender.

Section 2.2 Records.

Lender shall maintain in Lender’s records an account or accounts evidencing the indebtedness of Borrower hereunder, including the amounts of principal and interest payable and paid to Lender from time to time hereunder. The entries made in such account or accounts shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of Lender to maintain such account or accounts or any error therein shall not in any manner affect the obligation of Borrower to repay all outstanding principal, accrued and unpaid interest, and other amounts payable hereunder in accordance with the terms of this Agreement. In the event of any conflict between such account or accounts maintained by Lender with those maintained by Borrower pursuant to the immediately following paragraph, such account or accounts of Lender shall prevail in the absence of manifest error.

Borrower shall maintain in Borrower’s records an account or accounts evidencing the indebtedness of Borrower hereunder, including the amounts of principal and interest payable and paid to Lender from time to time hereunder. The entries made in such account or accounts shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of Borrower to maintain such account or accounts or any error therein shall not in any manner affect the obligation of Borrower to repay all outstanding principal, accrued and unpaid interest, and other amounts payable hereunder in accordance with the terms of this Agreement.

Section 2.3 Interest.

The outstanding principal amount of all Advances (except for the Existing Advances) under this Agreement shall accrue interest at a rate equal to five percent (5.0%) simple interest per annum from the corresponding Advance Date, which accrued interest shall be due and payable in arrears on the Maturity Date. Interest shall be calculated on the basis of a 360-day year and charged for the actual number of days elapsed to, but excluding, the Maturity Date (or such

other date on which all principal and accrued and unpaid interest hereunder is paid in full and this Agreement, and all commitments to make Advances hereunder, is terminated). Notwithstanding the foregoing, upon the occurrence, and during the continuation, of an Event of Default, interest shall accrue on all amounts outstanding hereunder at a rate equal to the otherwise applicable interest rate at such time plus an additional one percent (1.0%) simple interest per annum.

Section 2.4 Principal Payments.

Borrower agrees to duly and punctually pay all outstanding principal and accrued and unpaid interest hereunder on the Maturity Date. Borrower may voluntarily prepay the principal outstanding under this Agreement in whole or in part at any time, without premium or penalty, together with the accrued and unpaid interest on such prepaid principal. Lender shall apply payments and prepayments under this Agreement first to accrued and unpaid interest on the principal repaid or prepaid, then to outstanding principal and thereafter to any other amounts payable under this Agreement or any other Funding Documents.

Section 2.5 Payment Mechanics.

Borrower shall make each payment hereunder to Lender in immediately available funds on or prior to the day when due, in lawful money of the United States of America, at the location of Lender specified in Section 9.3 below, or at such other place or places as Lender may designate from time to time by written notice to Borrower. If any date upon which payment is due hereunder is not a Business Day, then the payment to be made on such date shall instead be due on the next Business Day.

ARTICLE 3

SECURITY INTEREST AND COLLATERAL MATTERS

Section 3.1 Grant of Security Interest.

As collateral security for the full, prompt, complete, and final payment and performance when due (whether at stated maturity, by acceleration, or otherwise) of all of the Secured Obligations and in order to induce Lender to enter into the Funding Documents and make the Advances, Borrower hereby collaterally assigns, conveys, mortgages, pledges, and hypothecates to Lender, and hereby grants to Lender, a security interest and Lien in and on all of Borrower’s right, title, and interest in, to, and under the following, whether now owned or hereafter acquired, to the extent that they consist of Program Assets (collectively, the “Collateral”):

(a) all Accounts;

(b) all Equipment, Goods, Inventory, and Fixtures;

(c) all Documents, Instruments, and Chattel Paper;

(d) all Letters of Credit and Letter-of-Credit Rights;

(e) all Investment Property;

(f) all contracts, intellectual property, and other General Intangibles, including all copyrights, trademarks, service marks, trade names, and patents;

(g) all money and all deposit accounts;

(h) all books and records relating to the Collateral; and

(i) to the extent not covered by clauses (a) through (h) of this sentence, all other assets, personal property, and rights of Borrower, whether tangible or intangible, all Proceeds and products of each of the foregoing, and all accessions to, substitutions and replacements for, and rents, profits, and products of, each of the foregoing, and any and all Proceeds of any insurance, indemnity, warranty, or guaranty payable to Borrower from time to time with respect to any of the foregoing.

Notwithstanding the foregoing, the security interest and Lien shall not extend to, and the term “Collateral” shall not include, any of the following (collectively, “Excluded Property”): (i) any permit or license or any contractual obligation entered into by Borrower, in each case permitted to be outstanding under the Merger Agreement, (A) that prohibits or requires the consent of any Person other than Borrower or an Affiliate thereof which has not been obtained as a condition to the creation by Borrower of a Lien on any right, title, or interest in such permit, license, contractual obligation, or other asset or (B) to the extent that any applicable state or federal law prohibits the creation of a Lien thereon, but only, with respect to the prohibition in (A) and (B), to the extent, and for as long as, such prohibition is not terminated or rendered unenforceable or otherwise deemed ineffective by the UCC or any other applicable law; (ii) any “intent to use” trademark applications for which a statement of use has not been filed (but only until such statement is filed) to the extent that the grant of a security interest therein would impair the validity or enforceability of such intent-to-use trademark application or the resulting trademark registration under applicable United States federal law; (iii) assets to the extent a security interest in such assets would result in material adverse tax consequences as reasonably determined by Borrower and Lender; and (iv) any Non-VISTA Assets; provided, however, “Excluded Property” shall not include any proceeds, products, substitutions, or replacements of Excluded Property (unless such proceeds, products, substitutions, or replacements would otherwise themselves constitute Excluded Property).

Section 3.2 Financing Statements.

Borrower hereby irrevocably authorizes Lender at any time and from time to time to file in any relevant jurisdiction any financing statements (including fixture filings) and amendments thereto that contain the information required by Article 9 of the UCC of each applicable jurisdiction for the filing of any financing statement or amendment relating to the Collateral, including (i) whether Borrower is an organization, the type of organization, and any organizational identification number issued to Borrower, and (ii) any financing or continuation statements or other documents for the purpose of perfecting, confirming, continuing, enforcing, or protecting the security interest granted by Borrower hereunder, without the signature of Borrower where permitted by law, including the filing of a financing statement describing the Collateral as “all assets now owned or hereafter acquired by Borrower or in which Borrower otherwise has

rights, and all proceeds of the foregoing.” Borrower agrees to provide all information described in the immediately preceding sentence to Lender promptly upon request by Lender. Lender may, with prior written notice to Borrower, also file with the United States Patent and Trademark Office and the United States Copyright Office (and any successor office and any similar office in any United States state or other country) this Agreement, an intellectual property security agreement, or other documents for the purpose of perfecting, confirming, continuing, enforcing, or protecting the security interest granted by Borrower hereunder, without the signature of Borrower where permitted by law, and naming Borrower as debtor and Lender as secured party.

Section 3.3 Further Assurances as to Security Matters.

Borrower shall take such further actions, and execute and/or deliver to Lender such additional financing statements, amendments, assignments, agreements, supplements, powers, and instruments, as may be deemed necessary or appropriate in order to perfect, preserve, and protect the security interest in the Collateral as provided herein and the rights and interests granted to Lender hereunder, and enable Lender to exercise and enforce its rights, powers, and remedies hereunder with respect to any Collateral, including the filing of any financing statements, continuation statements, and other documents under the UCC (or other similar laws) in effect in any jurisdiction with respect to the security interest created hereby, and the filing of intellectual property security agreements with the United States Patent and Trademark Office and the United States Copyright Office, all in form reasonably satisfactory to Lender in such offices wherever required by law to perfect, continue, and maintain a valid, enforceable, first-priority security interest in the Collateral as provided herein and to preserve the other rights and interests granted to Lender hereunder, as against third parties, with respect to the Collateral. Without limiting the generality of the foregoing, but subject to applicable law, Borrower shall make, execute, endorse, acknowledge, file, or refile and/or deliver to Lender from time to time upon reasonable request by Lender such lists, schedules, descriptions, and designations of the Collateral, statements, copies of warehouse receipts, bills of lading, documents of title, vouchers, invoices, schedules, confirmatory assignments, supplements, additional security agreements, conveyances, financing statements, transfer endorsements, powers of attorney, certificates, reports, and other assurances or instruments as Lender may reasonably request. If an Event of Default has occurred and is continuing, Lender may institute and maintain, in its own name or in the name of Borrower, such suits and proceedings as Lender may deem necessary or expedient to prevent any impairment of the security interest in, or the perfection thereof, in the Collateral. Each of Borrower and Lender shall be responsible for their own costs and expenses associated with the foregoing.

Stockholder intends this proxy to be irrevocable and coupled with an interest hereunder until the Expiration Date, hereby revokes any proxy previously granted by Stockholder with respect to the Shares and represents that none of such previously-granted proxies are irrevocable. The irrevocable proxy and power of attorney granted herein shall survive the death or incapacity of Stockholder and the obligations of Stockholder shall be binding on Stockholder’s heirs, personal representatives, successors, transferees and assigns.

Notwithstanding anything contained herein to the contrary, this irrevocable proxy shall automatically terminate upon the Expiration Date.

10. Other Remedies; Specific Performance. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with, and not exclusive of, any other remedy conferred hereby, or by Law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached.

17. Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction.

Exhibit 99.1

TuHURA Biosciences, Inc. Enters into Definitive Merger Agreement to Acquire

Kineta, Inc.

Opportunistic acquisition adds Phase 2 novel checkpoint inhibitor

(KVA12123) to TuHURA’s late stage pipeline

Targeting Phase 2a/b trial with KVA12123 in mutated NPM1 AML in 2025

Cross product and technology synergies build on TuHURA’s therapeutic focus

on overcoming primary and acquired resistance to cancer immunotherapy

Proposed Transaction expected to close in Q1 2025

TAMPA, FL and SEATTLE, WA, December 12, 2024 – TuHURA Biosciences, Inc. (Nasdaq: HURA) (“TuHURA”), a Phase 3 registration-stage immune-oncology company developing novel technologies to overcome resistance to cancer immunotherapy, and Kineta, Inc. (OTC Pink: KANT) (“Kineta”), a clinical-stage biotechnology company focused on the development of novel immunotherapies in oncology that address cancer immune resistance, today announced that they have entered into a definitive merger agreement in which TuHURA would acquire Kineta, including the rights to Kineta’s novel KVA12123 antibody, for a combination of cash and shares of TuHURA common stock via a merger transaction (the “Proposed Transaction”).

“We are pleased to have entered into this definitive agreement with Kineta, which represents the culmination of the Exclusivity and Right of First Offer Agreement that TuHURA and Kineta entered into in July 2024. Our strategy of providing Kineta this past summer with a $5 million exclusivity fee to restart and finish their Phase 1 monotherapy and combination with pembrolizumab trial demonstrated our view that the PK/PD profile would position KVA12123 as a potential best-in-class V-domain Ig suppressor of T-cell activation (VISTA)-inhibiting antibody. We believe the real potential for this class of checkpoint inhibitors resides in the treatment of blood related cancers. The data presented at the December 2024 ASH meeting indicates a strong correlation between NPM1 mutations (mNPM1) and elevated VISTA expression, particularly in the context of acute myeloid leukemia (AML), where high VISTA levels on leukemia cells, associated with mNPM1, can potentially contribute to immune evasion and disease progression impacting their treatment response. Given mNPM1 drives leukemogenesis through menin, and the introduction of menin inhibitors improving treatment responses in mNPM1-associated AML, a combination with a VISTA-inhibiting antibody could be the next step in improving response rates in AML,” commented James Bianco, M.D., President and Chief Executive Officer of TuHURA.

KVA12123 is a VISTA-blocking immunotherapy in development as a monoclonal antibody infusion drug dosed every two-week cycles. It is completing two clinical trials both as a monotherapy and in combination with Merck’s anti-PD1 therapy, KEYTRUDA^® (pembrolizumab), in patients with advanced treatment-refractory solid tumors. Competitive therapies targeting VISTA have demonstrated either poor monotherapy anti-tumor activity in preclinical models or induction of cytokine release syndrome (CRS) in human clinical trials. Through the combination of unique epitope binding and an optimized IgG1 Fc region, KVA12123 demonstrates strong monotherapy tumor growth inhibition in preclinical models without evidence of CRS in clinical trial participants. KVA12123 has been shown to de-risk the VISTA target and provides a novel approach to address immune suppression in the tumor microenvironment (TME) with a mechanism of action that is differentiated and complementary with T cell focused therapies. KVA12123 may be an effective immunotherapy for many types of cancer and represents the introduction of a new class of checkpoint inhibitors.

VISTA is a negative immune checkpoint that suppresses T cell function in a variety of solid tumors. High VISTA expression in tumor correlates with poor survival in cancer patients and has been associated with a lack of response to other immune checkpoint inhibitors. Blocking VISTA induces an efficient polyfunctional immune response to address immunosuppression and drives anti-tumor responses.

KVA12123 has completed enrollment in its monotherapy arm, demonstrating safety at its highest dose level (1000mg). Kineta anticipates completion of enrollment in the combination therapy arm where KVA12123 is administered with Merck’s anti-PD1 therapy, KEYTRUDA^® (pembrolizumab). Initial results were reported earlier this year at the American Association of Cancer Research (AACR) Annual Meeting 2024 and at the Society for Immunotherapy of Cancer (SITC) meeting, supporting best-in-class profile.

“Following a thorough review of exploring strategic alternatives for Kineta and the discussions held with TuHURA over the course of the past several months, we believe this acquisition by TuHURA maximizes shareholder value and provides an exciting development path forward for KVA12123. We believe KVA12123 has multiple synergies with both of TuHURA’s IFx and Delta receptor antibody-drug conjugate (ADC) and peptide drug conjugate (PDC) technologies and that a TuHURA acquisition will provide the necessary resources to advance KVA12123 through its clinical development, maximizing value for Kineta’s shareholders,” said Craig W. Philips, President of Kineta. “In addition to the TuHURA transaction, Kineta is continuing to pursue partnership opportunities for some of its other non-KVA12123-related products and technologies prior to the close of the TuHURA transaction.”

About the Proposed Transaction

Under the terms of the merger agreement, upon the completion of the Proposed Transaction, Kineta stockholders will receive their pro rata share (based on the number of Kineta fully diluted shares held by them) of aggregate merger consideration consisting of a combination of cash and shares of TuHURA common stock. The cash component of the aggregate merger consideration will be a base cash amount of $9,005,000 (consisting of a value of $15,000,000 minus the $5,995,000 advanced to Kineta under the Exclusivity and Right of First Offer Agreement) less the sum of Kineta’s working capital deficit at the closing of the Proposed Transaction and any working

capital loans made by TuHURA to Kineta between the signing of the merger agreement and closing of the Proposed Transaction. The share component of the aggregate merger consideration will consist of an aggregate of up to approximately 3,476,568 shares of TuHURA common stock, subject to a six-month holdback of approximately 869,142 of such shares to satisfy certain additional liabilities of the closing date that may be identified after the closing. As additional merger consideration, Kineta stockholders will be entitled to receive their pro rata share of certain payments that Kineta may receive after the closing from the potential pre-closing sale by Kineta of certain non-KVA12123 products and technologies.

In connection with the merger agreement, TuHURA and Kineta entered into a Clinical Trial Funding Agreement under which TuHURA agreed to continue to fund clinical trial expenses for KVA12123 in an amount of up to $900,000, which may be increased upon mutual agreement. The merger agreement also provides that Kineta may request the extension of up to $2,000,000 in working capital loans from TuHURA, $1,750,000 of which will be contingent on the completion of a financing transaction by TuHURA.

The merger agreement has been unanimously approved by the boards of directors of both companies and is subject to Kineta stockholder approval. The completion of the Proposed Transaction is also subject to the satisfaction or waiver of certain other conditions, such as the approval by TuHURA’s stockholders of an increase in the number of authorized shares of TuHURA common stock, Kineta’s working capital deficit not exceeding $12,000,000 at the time of closing, the effectiveness of a registration statement on Form S-4 registering the shares of TuHURA common stock issuable to the Kineta stockholders in the Proposed Transaction, and other customary closing conditions. The Proposed Transaction is currently expected to close in the first quarter of 2025.

About TuHURA Biosciences, Inc.

TuHURA Biosciences, Inc. (Nasdaq: HURA) is a Phase 3 registration-stage immuno-oncology company developing novel technologies to overcome primary and acquired resistance to cancer immunotherapy, two of the most common reasons cancer immunotherapies fail to work or stop working in the majority of patients with cancer.

TuHURA’s lead innate immune agonist candidate, IFx-2.0, is designed to overcome primary resistance to checkpoint inhibitors. TuHURA is preparing to initiate a single randomized placebo-controlled Phase 3 registration trial of IFx-2.0 administered as an adjunctive therapy to Keytruda^® (pembrolizumab) in first line treatment for advanced or metastatic Merkel Cell Carcinoma.

In addition to its innate immune agonist candidates, TuHURA is leveraging its Delta receptor technology to develop first-in-class bi-specific ADCs and PDCs targeting Myeloid Derived Suppressor Cells to inhibit their immune-suppressing effects on the TME to prevent T cell exhaustion and acquired resistance to checkpoint inhibitors and cellular therapies.

For more information on Kineta, please visit www.kinetabio.com.

Through the combination of unique epitope binding and an optimized IgG1 Fc region, KVA12123 has demonstrated strong tumor growth inhibition as both a monotherapy and in combination with other checkpoint inhibitors in preclinical models. KVA12123 provides a novel approach to address immune suppression in the TME with a mechanism of action that is differentiated and complementary with T cell focused therapies. KVA12123 may be an effective immunotherapy for many types of cancer including non-small cell lung carcinoma (NSCLC), colorectal, renal cell carcinoma, head and neck, and ovarian cancer.

In February 2024, Kineta announced a significant corporate restructuring to substantially reduce expenses and preserve cash. The restructuring included a significant workforce reduction and the suspension of enrollment of new patients in its ongoing VISTA-101 Phase 1/2 clinical trial evaluating KVA12123 in patients with advanced solid tumors. At that time, Kineta also announced that it was exploring strategic alternatives to maximize stockholder value.

These factors, risks and uncertainties include, but are not limited to: the completion of the Proposed Transaction on anticipated terms and timing, anticipated tax treatment and unforeseen liabilities, future capital expenditures, revenues, expenses, earnings, synergies, economic performance, indebtedness, financial condition, losses, pricing trends, future prospects, credit ratings, business and management strategies which may adversely affect each of TuHURA’s and Kineta’s business, financial condition, operating results and the price of their respective common stocks; the failure to satisfy the conditions to the completion of the Proposed Transaction, including the adoption of the merger agreement by the stockholders of Kineta and TuHURA’s completion of a financing transaction, in a timely manner, or at all, or the failure to satisfy any of the other conditions to the completion of the Proposed Transaction, or unexpected delays in satisfying any conditions; uncertainties related to Kineta’s cash level and ability to continue as a going concern; the price of TuHURA common stock and Kineta common stock could change before the completion of the Proposed Transaction, including as a result of uncertainty as to the long-term value of the common stock of TuHURA or as a result of broader stock market movements; risks relating to the amount of Kineta’s estimated net working capital at the closing of the Proposed Transaction, including any resulting reduction or adjustments to the merger consideration or failure to satisfy the condition that Kineta’s estimated net working capital deficit not exceed $12,000,000 at closing; uncertainties as to access to available financing, including the required financing of TuHURA, to complete the Proposed Transaction upon acceptable terms and on a timely basis or at all; the occurrence of any event, change or other circumstance that could give rise to the termination of the merger agreement, including a termination of the merger agreement under circumstances that could require Kineta to pay a termination fee to TuHURA; risks that the Proposed Transaction does not qualify as a reorganization under the Internal Revenue Code; the risk that, if the Proposed Transaction or another strategic transaction is not successfully completed, the Kineta board of directors may decide to pursue a dissolution and liquidation of Kineta; the effect of the announcement or pendency of the Proposed Transaction on Kineta’s or TuHURA’s business relationships, competition, business, financial condition, and operating

results; risks that the Proposed Transaction could disrupt current plans and operations of Kineta or TuHURA and the ability of Kineta or TuHURA to retain and hire key personnel; risks related to diverting either management team’s attention from ongoing business operations of Kineta or TuHURA; the outcome of any legal proceedings that may be instituted against Kineta or TuHURA related to the merger agreement or the Proposed Transaction; the ability of TuHURA to successfully integrate Kineta’s business or fully realize the anticipated synergies or other benefits expected from the Proposed Transaction; the ability of TuHURA to implement its plans, forecasts, expected financial performance and other expectations with respect to Kineta’s business or the combined business after the completion of the Proposed Transaction and realize additional opportunities, develop customer relationships, additional products and Kineta’s existing business; risks associated with third party contracts containing consent and/or other provisions that may be triggered by the Proposed Transaction; the potentially significant amount of any costs, fees, expenses, impairments or charges related to the Proposed Transaction; the risk of no amounts being payable under the Disposed Asset Payment Right as defined in the merger agreement; the potential dilution of TuHURA and Kineta stockholders’ ownership percentage of TuHURA after the Proposed Transaction as compared to their ownership percentage of TuHURA and Kineta, as applicable, prior to the Proposed Transaction; TuHURA and Kineta directors and executive officers having interests in the Proposed Transaction that are different from, or in addition to, the interests of TuHURA and Kineta stockholders generally; the possibility that TuHURA’s results of operations, cash flows and financial position after the Proposed Transaction may differ materially from the unaudited pro forma condensed combined financial information contained in the proxy statement/prospectus; macroeconomic conditions and geopolitical uncertainty in the global economy; uncertainty in the growth of the biopharmaceutical sector; the highly competitive industries TuHURA and Kineta operate in; actions by the U.S. or foreign governments, such as the imposition of additional export restrictions or tariffs; legislative, regulatory and economic developments affecting Kineta’s and TuHURA’s businesses; the evolving legal, regulatory and tax regimes under which Kineta and TuHURA operate; restrictions during the pendency of the Proposed Transaction that may impact Kineta’s or TuHURA’s ability to pursue certain business opportunities or strategic transactions; and unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism or outbreak of war or hostilities, as well as Kineta’s and TuHURA’s response to any of the aforementioned factors. The foregoing list of risks, uncertainties and factors is not exhaustive. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements.

You should carefully consider the foregoing factors and the other risks and uncertainties that affect the businesses of TuHURA and Kineta described in the “Risk Factors” section of their respective Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and other documents filed by either of them from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. All forward-looking statements by their nature address matters that involve risks and uncertainties, many of which are beyond TuHURA’s and Kineta’s control, and are not guarantees of future results. Readers are cautioned not to put undue reliance on forward-looking statements, and TuHURA and Kineta assume no obligation and do not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise, unless required by law. Neither TuHURA nor Kineta gives any assurance that either TuHURA or Kineta will achieve its expectations.
