**Item 29. CONTROL PERSONS**.

No person is directly or indirectly controlled by or under common control with Calamos Nasdaq® Autocallable Income ETF.

**Item 30. INDEMNIFICATION.**

Article IX of the Second Amended and Restated Trust Instrument of the Registrant (the "Trust Instrument") (Exhibit (a)(ii) to this registration statement) provides that, subject to certain exceptions and limitations, every person who is, or has been, a trustee or an officer or employee of the Trust or is or was serving at the request of the Trust as a trustee, director, officer, employee or agent of another organization in which the Trust has any interest as a shareholder, creditor or otherwise ("Covered Person") shall be indemnified by the Trust and each series to the fullest extent permitted by law against liability and against all expenses reasonably incurred or paid by him or her in connection with any claim, action, suit or proceeding in which he or she becomes involved as a party or otherwise by virtue of his or her being or having been a Covered Person and against amounts paid or incurred by him or her in the settlement thereof. To the extent required under the Investment Company Act of 1940, as amended, but only to such extent, no indemnification shall be provided hereunder to a Covered Person: (i) who shall have been adjudicated by a court or body before which the proceeding was brought to be liable to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office; or (ii) in the event of a settlement, unless there has been a determination that such Covered Person did not engage in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office: (A) by the court or other body approving the settlement; (B) by at least a majority of those trustees who are neither interested persons of the Trust nor are parties to the matter based upon a review of readily available facts (as opposed to a full trial-type inquiry); or (C) by written opinion of independent legal counsel based upon a review of readily available facts (as opposed to a full trial-type inquiry).

The Trust Instrument also provides that if any shareholder or former shareholder of any series is held personally liable solely by reason of his or her being or having been a shareholder and not because of his or her acts or omissions or for some other reason, the shareholder or former shareholder (or his or her heirs, executors, administrators or other legal representatives or, in the case of any entity, its general successor) shall be entitled out of the assets belonging to the applicable series to be held harmless from and indemnified against all loss and expense arising from such liability. The Trust, on behalf of the affected series, shall, upon request by such shareholder or former shareholder, assume the defense of any claim made against him or her for any act or obligation of the series and satisfy any judgment thereon from the assets belonging to the series. Neither the Trust nor the applicable series shall be responsible for satisfying any obligation arising from such a claim that has been settled by the shareholder without the prior written notice to, and consent of, the Trust. Except as otherwise specifically provided in this Trust Instrument or in the Bylaws, the Trust shall have no obligation to indemnify or hold harmless any shareholder against any loss or expense arising under any circumstances whether in connection with a proceeding of any kind or otherwise.

The Registrant, its trustees and officers, its investment adviser, the other investment companies advised by the Advisor and certain persons affiliated with them are insured, within the limits and subject to the limitations of the insurance, against certain expenses in connection with the defense of actions, suits or proceedings, and certain liabilities that might be imposed as a result of such actions, suits or proceedings. The insurance expressly excludes coverage for any trustee or officer whose personal dishonesty, fraudulent breach of trust, lack of good faith, or intention to deceive or defraud has been finally adjudicated or may be established or who willfully fails to act prudently.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the "Securities Act") may be permitted to trustees, officers, and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a trustee, officer, or controlling person of the Registrant in the successful defense of any action, suit, or proceeding) is asserted by such trustee, officer, or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Calamos ETF Trust

2020 Calamos Court

Naperville, IL 60563

Re: <u>Calamos ETF Trust</u>

Ladies and Gentlemen:

We have acted as special Delaware counsel to Calamos ETF Trust, a Delaware statutory trust (the "Trust"), in connection with certain matters relating to the formation of the Trust and the issuance of Shares of Calamos Nasdaq Autocallable Income ETF, a Series of the Trust (the "Fund" and such Shares, the "Registered Shares"). Capitalized terms used herein and not otherwise herein defined are used as defined in the Second Amended and Restated Trust Instrument of the Trust dated as of January 10, 2023 (the "Governing Instrument").

Calamos ETF Trust

November 20, 2025

In rendering this opinion, we have examined and relied on copies of the following documents, each in the form provided to us: Post-Effective Amendment No. 72 to Registration Statement No. 333-191151 under the Securities Act of 1933 and No. 74 to Registration Statement No. 811-22887 under the Investment Company Act of 1940 on Form N-1A of the Trust as filed with the Securities and Exchange Commission on or about the date hereof (the "Registration Statement"); the Amended and Restated Certificate of Trust of the Trust as filed in the Office of the Secretary of State of the State of Delaware (the "State Office") on January 13, 2023 (the "Certificate"); the Amended and Restated Certificate of Trust of the Trust as filed in the State Office on January 17, 2014; the Certificate of Trust of the Trust as filed in the State Office on June 17, 2013; the Trust Instrument of the Trust dated as of June 17, 2013 (the "Initial Governing Instrument"); the Amended and Restated Trust Instrument of the Trust dated as of December 16, 2022 (the "First A&R Governing Instrument"); the Governing Instrument; the Bylaws of the Trust adopted as of December 16, 2022 (the "Bylaws"); resolutions of the Board of Trustees of the Trust prepared for adoption at a meeting held on August 20, 2025 (the "August Resolutions"); resolutions of the Board of Trustees of the Trust prepared for adoption at a meeting held on October 9, 2025 (the "October Resolutions" and together with the August Resolutions, the "Resolutions" and the Resolutions collectively with the Registration Statement, the Governing Instrument and the Bylaws, the "Governing Documents"); and a certification of good standing of the Trust obtained as of a recent date from the State Office. In such examinations, we have assumed the genuineness of all signatures, the conformity to original documents of all documents submitted to us as copies or drafts of documents to be executed, and the legal capacity of natural persons to complete the execution of documents. We have further assumed for purposes of this opinion: (i) except to the extent addressed by our opinion in paragraph 1 below, the due formation or organization, valid existence and good standing of each entity that is a signatory to any of the documents reviewed by us under the laws of the jurisdiction of its respective formation or organization; (ii) the due adoption, authorization, execution and delivery, as applicable, by or on behalf of each of the parties thereto of the above-referenced agreements, instruments, certificates and other documents (including the Resolutions), and of all documents contemplated by the Governing Documents to be executed by investors desiring to become Shareholders; (iii) that the required consideration for the Shares is paid in accordance with the terms, conditions, requirements and procedures set forth in the Governing Documents and that the Shares are otherwise issued in accordance with the terms, conditions, requirements and procedures set forth in the Governing Documents and the Delaware Statutory Trust Act, 12 <u>Del</u>. <u>C</u>.<u> </u>§§ 3801 <u>et seq</u>. (the "Delaware Act"); (iv) that appropriate notation of the names and addresses of, the number of Shares held by, and the consideration paid by, Shareholders will be maintained in the appropriate registers and other books and records of the Trust in connection with the issuance or transfer of Shares; (v) that no event has occurred that would cause a termination or dissolution of the Trust or the Fund under Section 3 of Article X of the Initial Governing Instrument, Section 3 of Article X of the First A&R Governing Instrument or Section 3 of Article X of the Governing Instrument, as applicable; (vi) that the activities of the Trust have been and will be conducted in accordance with the terms of the Governing Instrument and the Delaware Act; (vii) that the "ETF Trust" as used in the August Resolutions is the Trust; (viii) that the Trust became, prior to or within 180 days following the first issuance of beneficial interests therein, a registered investment company under the Investment Company Act of 1940, as amended; (ix) that the Registered Shares constitute the Shares covered by the Registration Statement; and (x) that each of the documents examined by us is in full force and effect and has not been amended, supplemented or otherwise modified, except as herein referenced. We have not reviewed any documents other than those identified above in connection with this opinion, and we have assumed that there are no documents, facts or circumstances that are contrary to, or inconsistent with the opinions expressed herein. No opinion is expressed herein with respect to the requirements of, or compliance with, federal or state securities or blue sky laws. Further, we express no opinion on the sufficiency or accuracy of any registration or offering documentation relating to the Trust, the Fund or the Shares. As to any facts material to our opinion, other than those assumed, we have relied without independent investigation on the above-referenced documents and on the accuracy, as of the date hereof, of the matters therein contained.

Based on and subject to the foregoing, and limited in all respects to matters of Delaware law, it is our opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The Trust is a duly formed and validly existing statutory trust in good standing under the laws of the State of Delaware. The Fund is a validly existing Series of the Trust.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. The Registered Shares, when issued to Shareholders in accordance with the terms, conditions, requirements and procedures set forth in the Governing Documents, will be validly issued, fully paid and non-assessable Shares.

Calamos ETF Trust

November 20, 2025

We hereby consent to the filing of a copy of this opinion with the Securities and Exchange Commission as an exhibit to the Registration Statement. In giving this consent, we do not hereby admit that we come within the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended, or the rules and regulations of the Securities and Exchange Commission thereunder. This opinion speaks only as of the date hereof and is based on our understandings and assumptions as to present facts, and on the application of Delaware law as the same exist on the date hereof, and we undertake no obligation to update or supplement this opinion after the date hereof for the benefit of any person or entity (including any Shareholder) with respect to any facts or circumstances that may hereafter come to our attention or any changes in facts or law that may hereafter occur or take effect. This opinion is intended solely for the benefit of the Trust and the Shareholders in connection with the matters contemplated hereby and may not be relied upon by any other person or entity, or for any other purpose, without our prior written consent.
