●Leverage Risk - The Underlying Index uses leverage and will lose more money when the value of the Nasdaq-100 Index falls than a similar index that does not use leverage. The use of leverage increases the risk of a total loss of your investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.
●Counterparty Risk - The Fund may lose money if a counterparty does not meet its contractual obligations. Such losses may be significant.
●Correlation Risk - A number of factors may affect the Fund's ability to achieve a high degree of correlation with the Index. Fees, expenses, transaction costs, among other factors, will adversely impact the Fund's ability to meet its investment objective. In addition, the Fund's exposure may not be consistent with the Index. For example, the Fund may not have exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index.
●Equity and Market Risk - The Fund's investment strategy provides indirect exposure to equity markets. Equity markets are volatile, and the value of equity securities and other instruments correlated with equity markets may fluctuate dramatically from day to day. Equity markets are subject to corporate, political, regulatory, market, social, geopolitical and economic developments, including changes in interest and currency rates, inflation (or expectations for inflation), deflation (or expectations for deflation), global demand for particular products or resources, market instability, debt crises, embargoes, tariffs, sanctions and other trade barriers, regulatory or governmental trade or market control programs, recessions, supply chain disruptions, labor disturbances, environmental or man-made disasters, war, terrorism, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics), social unrest and other unforeseeable events.
●Industry Concentration Risk - The Index may have a significant portion of its value in issuers in an industry or group of industries. The Fund will allocate its investments to approximately the same extent as the Index. As a result, the Fund may be subject to greater market fluctuations than a fund that is more broadly invested across industries. As of May 31, 2026, the Index had a significant portion of its value in issuers in the communication services and information technology industry groups.
○Information Technology Industry Risk - Companies in this industry may experience: intense competition, obsolescence of existing technology, and changing economic conditions and government regulation.
●Money Market Instruments Risk - Adverse economic, political or market events affecting issuers of money market instru
ments, defaults by counterparties or changes in government regulations may have a negative impact on the performance of the Fund. The Fund's investments in money market instruments through an affiliated ETF are subject to the additional risk that the ETF's share price may fluctuate, including deviating from its net asset value during illiquid markets or during periods of high redemption activity.
●Non-Diversification Risk - The Fund has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund's volatility and increase the risk that the Fund's performance will decline based on the performance of a single issuer or the credit of a single counterparty.
●Index Performance Risk - The Index used by the Fund may underperform other asset classes and may underperform other similar indices. The Index is maintained by a third party provider unaffiliated with the Fund or ProShare Advisors. There can be no guarantee that the methodology underlying the Index or the daily calculation of the Index will be free from error.
●Market Price Variance Risk - Investors buy and sell Fund shares in the secondary market at market prices. Market prices may be different from the NAV per share of the Fund (i.e., the secondary market price may trade at a price greater than NAV (a premium) or less than NAV (a discount)). The market price of the Fund's shares will fluctuate in response to changes in the value of the Fund's holdings, supply and demand for shares and other market factors.
●Early Close/Late Close/Trading Halt Risk - An exchange or market may close early, close late or issue trading halts on specific securities or financial instruments. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.
●Tax Risk - To qualify for special tax treatment as a regulated investment company ("RIC"), the Fund must meet certain income, asset diversification, and distribution requirements. The Fund's investment strategies may be limited by the need to meet these requirements. For purposes of the qualifying income requirement, the treatment of the swaps and other derivatives that provide exposure to the Index is not entirely clear, and thus whether the income and gain therefrom is qualifying income is uncertain. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The federal income tax treatment of the swaps and other derivatives may not be as favorable as a direct investment in an underlying asset and may affect the timing, character and
