We believe our process provides key advantages for identifying quality companies and avoiding risks that many nonsustainable strategies overlook.

Environmental, social and governance (ESG) is based on the premise of investing in companies that have good environmental records, are ethically run and have a positive social impact.

An investment in the Fund(s) is subject to risks, and you could lose money on your investment in the Fund(s). There can be no assurance that the Fund(s) will achieve its investment objective. Your investment in the Fund(s) is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. The risks associated with an investment in the Fund(s) can increase during times of significant market volatility. The Fund(s) also has specific principal risks, which are described below. More detailed information regarding these risks can be found in the Fund’s prospectus.

The principal risks of investing in the Calamos Antetokounmpo Global Sustainable Equities ETF include: equity securities risk consisting of market prices declining in general, growth stock risk consisting of potential increased volatility due to securities trading at higher multiples, value stock risk, foreign securities risk, forward foreign currency contract risk, emerging markets risk, small and mid-sized company risk and portfolio selection risk. As a result of political or economic instability in foreign countries, there can be special risks associated with investing in foreign securities, including fluctuations in currency exchange rates, increased price volatility and difficulty obtaining information. In addition, emerging markets may present additional risk due to the potential for greater economic and political instability in less developed countries.

The MSCI ACWI (net) Index is a free float-adjusted market capitalization weighted index that is designed to measure the equity market performance of developed markets and emerging markets.

The Fund’s ESG policy could cause it to perform differently compared to similar funds that do not have such a policy. The application of the social and environmental standards of Calamos Advisors may affect the Fund’s exposure to certain issuers, industries, sectors, and factors that may impact the relative financial performance of the Fund—positively or negatively—depending on whether such investments are in or out of favor.

Calamos Antetokounmpo Asset Management LLC (“CGAM”), an investment adviser registered with the SEC under the Investment Advisers Act of 1940, serves as the Fund’s adviser (“Adviser”). CGAM is jointly owned by Calamos Advisors LLC 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.

Mr. Antetokounmpo serves on the Adviser's Board of Directors and has indirect control of half of the Adviser's Board.

Mr. Antetokounmpo is not a portfolio manager of the Fund and will not be involved in the day-to-day management of the Fund's investments, and neither Original C nor Mr. Antetokounmpo shall provide any “investment advice” to the Fund. Mr. Antetokounmpo provided input in selecting the initial strategy for the Fund.

Mr. Antetokounmpo will be involved with marketing efforts on behalf of the Adviser. If Mr. Antetokounmpo is no longer involved with the Fund or the Adviser then “Antetokounmpo” will be removed from the name of the Fund and the Adviser. Further, shareholders would be notified of any change in the name of the Fund or its strategy.

The Adviser is jointly owned and controlled by Calamos Advisors LLC and, indirectly, by Mr. Antetokounmpo, a well-known professional athlete. Unanticipated events, including, without limitation, death, adverse reputational events or business disputes, could result in Mr. Antetokounmpo no longer being associated or involved with the Adviser. Any such event could adversely impact the Fund and result in shareholders experiencing substantial losses.
