High Yield — Interest Rate Hedged :: 3

Investment Objective

ProShares High Yield – Interest Rate Hedged (the “Fund”) seeks investment results, before fees and expenses, that track the performance of the FTSE High Yield (Treasury Rate-Hedged) Index (the “Index”).

Fees and Expenses of the Fund

The table below describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees	0.50%
Other Expenses	0.00%
Total Annual Fund Operating Expenses	0.50%

Example: This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem or hold all of your shares at the end of each period. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your approximate costs would be:

1 Year	3 Years	5 Years	10 Years
$51	$160	$280	$628

The Fund pays transaction and financing costs associated with the purchase and sale of securities and derivatives. These costs are not reflected in the table or the example above.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when the Fund’s shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the example above, affect the Fund’s performance. During the most recent fiscal year, the Fund’s annual portfolio turnover rate was 27% of the average value of its portfolio. This portfolio turnover rate is calculated without regard to cash instruments or derivatives transactions. If such transactions were included, the Fund’s portfolio turnover rate would be significantly higher.

Principal Investment Strategies

The Fund invests in financial instruments that ProShare Advisors believes, in combination, should track the performance of the Index.

The Index is comprised of (a) long positions in USD-denominated high yield corporate bonds (“high yield bonds”) and (b) short positions in U.S. Treasury notes or bonds (“Treasury Securities”) of, in aggregate, approximate equivalent duration to the high yield bonds. The Index is constructed and maintained by FTSE International Limited. By taking these short Treasury Securities positions, the Index seeks to mitigate the negative impact of rising Treasury interest rates (“interest rates”) on the performance of high yield bonds (conversely limiting the positive impact of falling interest rates). The short positions are not intended to mitigate other factors influencing the price of high yield bonds, such as credit risk, which may have a greater impact than rising or falling interest rates. The long high yield bond positions included in the Index are designed to represent the more liquid universe of high yield bonds offered within the United States. Currently, the bonds eligible for inclusion in the Index include high yield bonds that are issued by companies domiciled in the U.S. and Canada, and that: are fixed rate and non-convertible (including callable bonds); have a maximum rating of Ba1/BB+ and minimum rating of Ca/C by both Moody’s Investors Service, Inc. (“Moody’s”) and Standard and Poor’s Financial Services, LLC (“S&P”); and are subject to minimum issue outstanding, minimum time-to-maturity and maximum time from issuance criteria. Pay-in-kind bonds are excluded. No more than two issues from each issuer are allowed, and no more than two percent (2%) of the Index may be allocated to any single issuer. The Index is reconstituted and rebalanced (including a reset of the interest rate hedge) on a monthly basis. Relative to a long-only investment in the same high yield bonds, the Index is designed to outperform in a rising interest rate environment and underperform in a falling or static interest rate environment. Performance of the Index may be particularly poor in risk-averse, flight-to-quality environments when it is common for high yield bonds to decline in value and for interest rates to fall. In addition, the performance of the Index, and by extension the Fund, depends on many factors beyond rising or falling interest rates, such as the perceived level of credit risk in the high yield bond positions. These factors may be as or more important to the performance of the Index than the impact of interest rates. As such, there is no guarantee that the Index, and accordingly, the Fund, will have positive performance even in environments of sharply rising interest rates. The Index is published under the Bloomberg ticker symbol “CFIIHYHG.”

Under normal circumstances, the Fund will invest at least 80% of its total assets in high-yield bonds included in the Index.

The Fund will invest principally in the financial instruments listed below.

•Debt Instruments — The Fund invests in debt instruments, primarily high yield bonds, that are issued by corporate issuers that are rated below “investment-grade” by both Moody’s and S&P. Credit rating agencies evaluate issuers and assign ratings based on their opinions of the issuer’s

ability to pay interest and principal as scheduled. Those issuers with a greater risk of default — not paying interest or principal in a timely manner — are rated below investment grade. Such debt instruments may include Rule 144A securities, which generally are restricted securities that are only available to “qualified” investors.

•Derivatives — Financial instruments whose value is derived from the value of an underlying asset or assets, such as stocks, bonds, ETFs, interest rates or indexes. The Fund primarily invests in derivatives as a substitute for obtaining short exposure in U.S. Treasury Securities but may also do so to a limited extent to obtain high yield bond exposure. These derivatives principally include:

○Futures Contracts — Standardized contracts that obligate the parties to buy or sell an asset at a predetermined price and date in the future. The Fund will use futures contracts to obtain short exposure to U.S. Treasury Securities.

ProShare Advisors uses a mathematical approach to investing in which it determines the type, quantity and mix of investment positions that it believes, in combination, the Fund should hold to produce returns consistent with its investment objective. The Fund seeks to remain fully invested at all times in financial instruments that, in combination, provide exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining exposure consistent with the investment objective.

Please see “Investment Objectives, Principal Investment Strategies and Related Risks” in the Fund’s Prospectus for additional details.

Principal Risks

•High Yield Risk — Investment in or exposure to high yield (lower rated) debt instruments (also known as “junk bonds”) may involve greater levels of credit, prepayment, liquidity and valuation risk than for higher rated instruments. High yield debt instruments may be more sensitive to economic changes, political changes, or adverse developments specific to a company than other fixed income instruments. These securities are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and a potential lack of a secondary or public market for securities. High yield debt instruments are considered speculative with respect to the issuer’s continuing ability to make principal and interest payments and, therefore, such instruments generally involve greater risk of default or price changes than higher rated debt instruments. Furthermore, the transaction costs associated with the purchase and sale of high yield debt instruments may vary greatly depending upon a number of factors and may adversely affect the Fund’s performance.

•Hedging Risk — The Index seeks to mitigate the potential negative impact of rising interest rates on the performance of high yield bonds. The short positions in U.S. Treasury Securities are not intended to mitigate credit risk or other factors influencing the price of high yield bonds, which may have a greater impact than rising or falling interest rates. There is no guarantee that the short positions will completely eliminate the interest rate risk of the long high yield bond positions. The hedge cannot fully account for changes in the shape of the interest rate (yield) curve. Because the duration hedge is reset on a monthly basis, interest rate risk can develop intra-month that is not addressed by the hedge.

When interest rates fall, an unhedged investment in the same high yield bonds will outperform the Fund. The performance of the Fund could be particularly poor if high yield bond credit deteriorates at the same time interest rates fall. Furthermore, when interest rates remain unchanged, an investment in the Fund will underperform a long-only investment in the same high yield bonds due to the ongoing costs associated with short exposure to Treasury securities and other factors.

The Index may also contain a significant allocation to callable high yield bonds, which are subject to prepayment risk; callable bonds may have lower sensitivity to interest rate declines than non-callable bonds or U.S. Treasury Securities. In certain falling interest rate environments, this could result in disproportionately larger losses in the short Treasury positions relative to the gains in the long high yield bond positions attributable to falling interest rates.

•Risks Associated with the Use of Derivatives — Investing in derivatives to obtain exposure may be considered aggressive and may expose the Fund to greater risks including counterparty risk and correlation risk. The Fund may lose money if its derivatives do not perform as expected.

•Counterparty Risk — The Fund may lose money if a counterparty does not meet its contractual obligations.

•Debt Instrument Risk — Debt instruments are subject to adverse issuer, political, regulatory, market and economic developments, as well as developments that affect specific economic sectors, industries or segments of the market. Debt markets can be volatile and the value of instruments correlated with these markets may fluctuate dramatically from day to day.

•Credit Risk — Due to its exposure to debt instruments, the Fund will be subject to credit risk which is the risk that an issuer of debt instruments is unwilling or unable to make timely payments to meet its contractual obligations. When credit risk increases, the price of the debt instruments that comprise the Index will typically decrease. Conversely, when credit risk of the debt instruments decreases, the level of the Index will typically increase. By using sampling techniques, the Fund may be overexposed to certain debt

instruments that would adversely affect the Fund upon the markets’ perceived view of increased credit risk or upon a downgrade or default of such instruments. During an economic downturn, rates of default tend to increase. The hedging methodology of the Index does not seek to mitigate credit risk.

•Interest Rate Risk — Interest rate risk is the risk that debt instruments or related financial instruments may fluctuate in value due to changes in interest rates. A wide variety of factors can cause interest rates to fluctuate (e.g., central bank monetary policies, inflation rates, general economic conditions, etc.). Commonly, investments subject to interest rate risk will decrease in value when interest rates rise and increase in value when interest rates decline. A rising interest rate environment may cause the value of debt instruments to decrease and adversely impact the liquidity of debt instruments. Without taking into account other factors, the value of securities with longer maturities typically fluctuates more in response to interest rate changes than securities with shorter maturities. These factors may cause the value of an investment in the Fund to change.

The Fund seeks to mitigate this risk by taking short positions in U.S. Treasury Securities; such short positions should increase in value in rising interest rate environments and should decrease in value in falling interest rate environments. The Fund does not attempt to mitigate credit risk or other factors which may have a greater influence on its investments than interest rate risk.

•Prepayment Risk — Many types of debt instruments are subject to prepayment risk, which is the risk that the issuer of the security will repay principal (in part or in whole) prior to the maturity date. Debt instruments allowing prepayment may offer less potential for gains during a period of declining interest rates, as the proceeds may be reinvested at lower interest rates.

•Long/Short Risk — The Fund seeks long exposure to certain factors and short exposure to certain other factors. There is no guarantee that the returns on the Fund’s long or short positions will produce positive returns and the Fund could lose money if either or both the Fund’s long and short positions produce negative returns. Seeking short exposure may be considered an investment aggressive technique. Any income, dividends, or payments by the assets underlying the Fund’s short positions will negatively impact the Fund.

•Restricted Securities Risk — Privately issued securities are restricted securities that are not publicly traded, and may be less liquid than those that are publicly traded. At times, such securities cannot be readily bought or sold and the Fund might be unable to acquire or dispose of such securities promptly or at reasonable prices, which may result in a loss to the Fund. A restricted security that was liquid at the time of purchase may subsequently become illiquid.

•Foreign Investments Risk — Exposure to securities of foreign issuers may provide the Fund with increased risk. Foreign

investments may be more susceptible to political, social, economic and regional factors than may be the case with U.S. securities. In addition, markets for foreign investments are usually less liquid, more volatile and significantly smaller than markets for U.S. securities, which may affect, among other things, the Fund’s ability to purchase or sell foreign investments at appropriate times and prices. Because of differences in settlement times and/or foreign market holidays, transactions in a foreign market may take place one or more days after the necessary exposure to these investments is determined.

•Correlation Risk — The Fund’s exposure may not be consistent 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 may not have exposure to all of the bonds in the Index, its weighting of the bonds may be different from that of the Index, and it may invest in instruments not included in the Index.

•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, 2023, the Index had a significant portion of its value in issuers in the industrials industry group.

○Industrials Industry Risk — Companies in this industry may experience: adverse effects on stock prices by supply and demand both for their specific product or service and for industrials industry products in general; declining demand; and changing government regulation.

•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. Because of the nature of high yield bonds, shares typically trade at a larger premium or discount to the value of the Fund’s holdings than shares of many other ETFs.

•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.

Reflects no deduction for fees, expenses or taxes. Adjusted to reflect

the reinvestment of income paid by issuers in the Index. “Since Inception” returns are calculated from the date the Fund commenced operations, not the date of inception of the Index.

Average annual total returns are shown on a before- and after-tax basis for the Fund. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold shares through tax-deferred arrangements, such as a retirement account. After-tax returns may exceed the return before taxes due to a tax benefit from realizing a capital loss on a sale of shares.

Management

The Fund is advised by ProShare Advisors. Alexander Ilyasov, Senior Portfolio Manager, and James Linneman, Portfolio Manager, have jointly and primarily managed the Fund since April 2019 and March 2022, respectively.

Purchase and Sale of Fund Shares

The Fund will issue and redeem shares only to Authorized Participants (typically broker-dealers) in exchange for the deposit or delivery of a basket of assets (securities and/or cash) in large blocks, known as Creation Units. Shares of the Fund may only be purchased and sold by retail investors in secondary market transactions through broker-dealers or other financial intermediaries. Shares of the Fund are listed for trading on a national securities exchange and because shares trade at market prices rather than NAV, shares of the Fund may trade at a price greater than NAV (premium) or less than NAV (discount). In addition to brokerage commissions, investors incur the costs of the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”). The bid-ask spread varies over time for Fund shares based on trading volume and market liquidity. Recent information, including information about a Fund’s NAV, market price, premiums and discounts, and bid-ask spreads, is included on the Fund’s website (www.proshares.com).

Tax Information

Income and capital gains distributions you receive from the Fund generally are subject to federal income taxes and may also be subject to state and local taxes. The Fund intends to distribute income, if any, monthly, and capital gains, if any, at least annually. Distributions for this Fund may be higher than those of most ETFs.
