Notes to Schedule of Investments (Unaudited)

Note 1 – Organization and Significant Accounting Policies

Organization. CALAMOS INVESTMENT TRUST, a Massachusetts business trust organized December 21, 1987 (the “Trust”), consists of twenty series, Market Neutral Income Fund, Hedged Equity Fund, Phineus Long/Short Fund, Merger Arbitrage Fund, Convertible Fund, Global Convertible Fund, Timpani Small Cap Growth Fund, Timpani SMID Growth Fund, Growth Fund, Growth and Income Fund, Dividend Growth Fund, Select Fund , International Growth Fund, Evolving World Growth Fund, Global Equity Fund, Global Opportunities Fund, International Small Cap Growth Fund, Total Return Bond Fund, High Income Opportunities Fund, and Short-Term Bond Fund (each a "Fund" and collectively the "Funds"). The Trust is registered under the Investment Company Act of 1940 as amended (the “1940 Act”) as an open-end management investment company. The Trust currently offers Class A, Class C (except Timpani SMID Growth Fund and Short-Term Bond Fund), and Class I shares of each of the Funds. Class R6 shares are offered in Market Neutral Income Fund, Timpani Small Cap Growth Fund, Timpani SMID Growth Fund, Growth and Income Fund, International Growth Fund, Global Equity Fund, and International Small Cap Growth Fund only.

Significant Accounting Policies. The Schedules of Investments have been prepared in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) and the Funds are each considered an investment company under U.S. GAAP and follow the accounting and reporting guidance applicable to investment companies. The following summarizes the significant accounting policies of the Funds:

Fund Valuation. The Trust's Board of Trustees ("Board" or "Trustees"), including a majority of the Trustees who are not "interested persons" of the Trust, have designated Calamos Advisors LLC ("Calamos Advisors", or the "Advisor") to perform fair valuation determinations related to all Fund investments under the oversight of the Board. As "valuation designee" the Calamos Advisors has adopted procedures to guide the determination of the net asset value ("NAV") on any day on which the Fund's NAVs are determined. The valuation of the Funds’ 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 each 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.

Fixed income securities, bank loans, certain convertible preferred securities, and non-exchange traded derivatives are normally valued by independent pricing services or by dealers or brokers who make markets in such securities. Valuations of such fixed income securities, bank loans, certain convertible preferred securities, and non-exchange traded derivatives consider yield or price of equivalent securities of comparable quality, coupon rate, maturity, type of issue, trading characteristics and other market data and do not rely exclusively upon exchange or over-the-counter prices.

Trading on European and Far Eastern exchanges and over-the-counter markets is typically completed at various times before the close of business on each day on which the New York Stock Exchange (“NYSE”) is open. Each security trading on these exchanges or in over-the-counter markets may be valued utilizing a systematic fair valuation model provided by an independent pricing service approved by the Board. The valuation of each security that meets certain criteria in relation to the valuation model is systematically adjusted to reflect the impact of movement in the U.S. market after the foreign markets close. Securities that do not meet the criteria, or that are principally traded in other foreign markets, are valued as of the last reported sale price at the time the respective 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 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 respective Fund’s NAV is not calculated.

If the Advisor's pricing committee 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 pricing committee.

Each Fund also may use fair value pricing, pursuant to guidelines adopted by Calamos Advisors, 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 Calamos Advisors, 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.

Option Transactions. For hedging and investment purposes, each Fund may purchase or write (sell) put and call options. One of the risks associated with purchasing an option is that the Fund pays a premium whether or not the option is exercised. Additionally, the Fund bears the risk of loss of premium and change in value should the counterparty not perform under the contract. The Fund as writer of an option bears the market risk of an unfavorable change in the price of the security underlying the written option.

Forward Foreign Currency Contracts. Each Fund may engage in portfolio hedging with respect to changes in currency exchange rates by entering into forward foreign currency contracts to purchase or sell currencies. A forward foreign currency contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated forward rate. Risks associated with such contracts include, among other things, movement in the value of the foreign currency relative to the U.S. dollar and the ability of the counterparty to perform. The net unrealized gain, if any, represents the credit risk to the Fund on a forward foreign currency contract. The contracts are valued daily at forward foreign exchange rates.

As of July 31, 2024, any outstanding forward foreign currency contracts, if any, are listed on each Fund’s Schedule of Investments.

Note 2 – Short Sales

Securities sold short represent obligations to deliver the securities at a future date. A Fund may sell a security it does not own in anticipation of a decline in the value of that security before the delivery date. When the Fund sells a security short, it must borrow the security sold short and deliver it to the broker-dealer through which it made the short sale. Dividends paid on securities sold short are disclosed as an expense on the Statements of Operations. A gain, limited to the price at which a Fund sold the security short, or a loss, unlimited in size, will be realized upon the termination of a short sale.

To secure its obligation to deliver to the broker-dealer the securities sold short, a Fund must segregate an amount of cash or liquid securities with its custodian equal to any excess of the current market value of the securities sold short over any cash or liquid securities deposited as collateral with the broker in connection with the short sale (not including the proceeds of the short sale). As a result of that requirement, a Fund will not gain any leverage merely by selling short, except to the extent that it earns interest or other income or gains on the segregated cash or liquid securities while also being subject to the possibility of gain or loss from the securities sold short.

Note 3 – Fair Value Measurements

Various inputs are used to determine the value of each 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 each Fund's own judgments about assumptions market participants would use in determining fair value) when observable inputs are unavailable.

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 each Fund's investments. The summary of the inputs used in valuing each Fund's holdings are available after each Fund's Portfolio.
