Notes to Schedule of Investments (Unaudited)

Note 1 – Organization and Significant Accounting Policies

Organization. Calamos ETF Trust (the “Trust”), a Delaware statutory trust organized on June 17, 2013, consists of four series, including Calamos Antetokounmpo Global Sustainable Equities ETF (the “Fund”), which commenced operations on February 3, 2023. The Trust is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. Prior to commencement of operations, the Fund had issued 4,000 shares of beneficial interest at an aggregate purchase price of $100,000 to Calamos Investments, LLC, the parent of Calamos Advisors, LLC.

The Fund is a diversified, actively managed exchange-traded fund (“ETF”). The Fund’s investment objective is long-term capital appreciation. The Fund offers and issues Shares at net asset value (“NAV”) only in aggregations of a specified number of Shares, generally in exchange for a basket of securities constituting the portfolio holdings of the Fund, together with the deposit of a specified cash payment, or, in certain circumstances, for an all cash payment. Shares of the Fund are listed and principally traded on NYSE Arca, Inc.(the “Exchange”). Shares will trade on the Exchange at market prices that may be below, at, or above NAV.

Calamos Antetokounmpo Asset Management LLC (“CGAM”, or the "Adviser"), serves as the Fund’s adviser. CGAM is jointly owned by Calamos Advisors LLC (“Calamos Advisors”) and Original C Fund, LLC, an entity whose voting rights are wholly owned by Original PE, LLC which, in turn, is wholly owned by Giannis Sina Ugo Antetokounmpo. Calamos Advisors serves as the Fund’s subadviser (“Subadviser”).

Significant Accounting Policies. The Schedule of Investments has been prepared in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) and the Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies. The following summarizes the significant accounting policies of the Fund:

Fund Valuation. The Fund's Board of Trustees ("Board" or "Trustees"), including a majority of the Trustees who are not "interested persons" of the Fund, have designated the Adviser to perform fair valuation determinations related to all Fund investments under the oversight of the Board. As "valuation designee" the Adviser has adopted procedures to guide the determination of the NAV on any day on which the Fund's NAVs are determined. The valuation of the Fund's investments is in accordance with these procedures.

Fund securities that are traded on U.S. securities exchanges, except option securities, are valued at the official closing price, which is the last current reported sales price on its principal exchange at the time the Fund determines its NAV. Securities traded in the over-the-counter market and quoted on The NASDAQ Stock Market are valued at the NASDAQ Official Closing Price, as determined by NASDAQ, or lacking a NASDAQ Official Closing Price, the last current reported sale price on NASDAQ at the time a Fund determines its NAV. When a last sale or closing price is not available, equity securities, other than option securities, that are traded on a U.S. securities exchange and other equity securities traded in the over-the-counter market are valued at the mean between the most recent bid and asked quotations on its principal exchange in accordance with guidelines adopted by the Board. Each option security traded on a U.S. securities exchange is valued at the mid-point of the consolidated bid/ask quote for the option security, also in accordance with guidelines adopted by the Board. Each over-the-counter option that is not traded through the Options Clearing Corporation is valued either by an independent pricing agent approved by the Board or based on a quotation provided by the counterparty to such option under the ultimate supervision of the Board.

Securities that are principally traded in foreign markets are valued as of the last reported sale price at the time the Fund determines its NAV, or when reliable market prices or quotations are not readily available, at the mean between the most recent bid and asked quotations as of the close of the appropriate exchange or other designated time. Trading of foreign securities may not take place on every New York Stock Exchange ("NYSE") business day. In addition, trading may take place in various foreign markets on Saturdays or on other days when the NYSE is not open and on which the Fund's NAV is not calculated.

If the valuation designee determines that the valuation of a security in accordance with the methods described above is not reflective of a fair value for such security, the security is valued at a fair value by the valuation designee.

The Fund also may use fair value pricing, pursuant to guidelines adopted by the Adviser, if trading in the security is halted or if the value of a security it holds is materially affected by events occurring before the Fund's pricing time but after the close of the primary market or exchange on which the security is listed. Those procedures may utilize valuations furnished by pricing services approved by the Adviser, which may be based on market transactions for comparable securities and various relationships between securities that are generally recognized by institutional traders, a computerized matrix system, or appraisals derived from information concerning the securities or similar securities received from recognized dealers in those securities.

When fair value pricing of securities is employed, the prices of securities used by the Fund to calculate its NAV may differ from market quotations or official closing prices. There can be no assurance that the Fund could purchase or sell a portfolio security at the price used to calculate the Fund’s NAV.

Foreign Currency Translation. Values of investments and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars using a rate quoted by a major bank or dealer in the particular currency market, as reported by a recognized quotation dissemination service.

Note 2 – Fair Value Measurements

Various inputs are used to determine the value of the Fund's investments. These inputs are categorized into three broad levels as follows:

· Level 1 – Prices are determined using inputs from unadjusted quoted prices from active markets (including securities actively traded on a securities exchange) for identical assets.

· Level 2 – Prices are determined using significant observable market inputs other than unadjusted quoted prices, including quoted prices of similar securities, fair value adjustments to quoted foreign securities, interest rates, credit risk, prepayment speeds, and other relevant data.

· Level 3 – Prices reflect unobservable market inputs (including the Fund's own judgments about assumptions market participants would use in determining fair value) when observable inputs are unavailable.

3

Debt securities are valued based upon evaluated prices received from an independent pricing service or from a dealer or broker who makes markets in such securities. Pricing services utilize various observable market data and as such, debt securities are generally categorized as Level 2. The levels are not necessarily an indication of the risk or liquidity of the Fund's investments.

The following is a summary of the inputs used in valuing the Fund's holdings at fair value:

	LEVEL 1		LEVEL 2		LEVEL 3		TOTAL
Assets:
Common Stocks	$	10,831,729	$	—	$	—	$	10,831,729
Total	$	10,831,729	$	—	$	—	$	10,831,729
