Performance data quoted represents past performance and is no guarantee of future results. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than the original cost. Current performance may be lower or higher than the performance data quoted. Returns for periods of less than one year are not annualized.
The market price returns are based on the official closing price of an ETF share or, if the official closing price isn’t available, the midpoint between the national best bid and national best offer (“NBBO”) as of the time the ETF calculates current NAV per share, and do not represent the returns you would receive if you traded shares at other times. NAVs are calculated using prices as of 4:00 PM Eastern Time. The first trading date is typically several days after the fund inception date. Therefore, NAV is used to calculate market returns prior to the first trade date because there is no bid/ask spread until the fund starts trading.

Risk Information
Carefully consider the Fund’s investment objectives, risk factors, charges and expenses before investing. This and additional information can be found in the Fund’s prospectus or summary prospectus, which may be obtained by visiting www.temaetfs.com/DISK. Read the prospectus carefully before investing.
Investing involves risk including possible loss of principal. There is no guarantee the fund's investment strategy will be successful.
Sector Focus Risk: The Fund may invest a significant portion of its assets in one or more sectors and thus will be more susceptible to the risks affecting those sectors than funds that have more diversified holdings across a number of sectors. The Fund anticipates that it may be subject to some or all of the risks described below.
Memory Companies Risk: The Fund invests in Memory Companies, which may have limited product lines, markets, financial resources or personnel and are subject to the risks of changes in business cycles, world economic growth, technological progress and government regulation. These companies are also heavily dependent on intellectual property rights, and challenges to or misappropriation of such rights could have a material adverse effect on such companies. Securities of Memory Companies tend to be more volatile than securities of companies that rely less heavily on technology. Memory Companies typically engage in significant amounts of spending on research and development, and rapid changes to the field could have a material adverse effect on a company’s operating results. Additionally, the development, manufacturing, and commercialization of semiconductor memory technologies, including HBM, DRAM, SRAM, RAM, MRAM, ReRAM and NAND, as well as related subsystems, equipment, materials, and services, are complex and evolving, and may face unforeseen technical challenges (including yield and integration issues), supply chain disruptions, intense competition and pricing volatility, regulatory developments (including export controls), and market acceptance uncertainties. As a result, investments in Memory Companies may be subject to higher levels of risk and volatility.
Semiconductor Companies Risk: The Fund invests in companies primarily involved in the development, design, distribution, manufacture and sale of semiconductors. Semiconductor companies are significantly affected by rapid obsolescence, intense competition and global demand. The Fund is also subject to the risk that the securities of such issuers may underperform the market as a whole due to legislative or regulatory changes. The prices of securities of semiconductor companies may fluctuate widely in response to such events.
Information Technology Sector Risk: Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on their profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of any of these rights may adversely affect the profitability of these companies or the Fund’s performance.
