**Investment Objective**

ProShares Nanotechnology ETF (the "Fund") seeks investment results, before fees and expenses, that track the performance of the Solactive Nanotechnology 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**<br> (expenses that you pay each year as a percentage <br> of the value of your investment)<br>|  |
| Management Fees | 0.58% |
| Other Expenses | 0.00% |
| **Total Annual Fund Operating Expenses** | **0.58%** |

---

**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** |
| $59 | $186 | $324 | $726 |

---

The Fund pays transaction and financing costs associated with the purchase and sale of securities. 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 45% of the average value of its portfolio.

**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 designed to measure the performance of companies that have business operations in the field of nanotechnology. The index provider uses a natural language processing algorithm to identify companies that fall into one or more of the following categories: (1) production of nanotechnology,

which can be defined as the use of matter on an atomic and molecular level; (2) active in the fields of nanomedicine, nanomaterials, nanoelectronics, nanometrology or molecular nanotechnology; and (3) development of technologies that promote advances in or research related to nanotechnologies.

The index provider determines whether a company falls into those categories by using an automated scan of company filings and other public information to search for terms and phrases which identify companies that have or are expected to have significant exposure to nanotechnology. The index provider reviews each company and excludes any company that does not have relevant business exposure. The identified companies are then ranked based on the level of exposure to nanotechnology, as determined by the automated scan. The top 30 companies are selected into the Index. Selected companies are weighted based on market capitalization, subject to a 4.5% limit for any single company. The Index's composition and the assigned weights are reevaluated every May and November. The Index is constructed and maintained by Solactive AG. More information about the Index can be found using the Bloomberg ticker symbol "SOLNANON."

Under normal circumstances, the Fund will invest at least 80% of its total assets in components of the Index or in instruments with similar economic characteristics.

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

&nbsp;&nbsp;&nbsp;&nbsp;●**Equity Securities** — Common stock issued by public companies.

&nbsp;&nbsp;&nbsp;&nbsp;●**Depositary Receipts** — The Fund may invest in depositary receipts, which principally include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;○**American Depositary Receipts (ADRs),** which represent the right to receive securities of foreign issuers deposited in a bank or trust company and are an alternative to purchasing the underlying securities in their national markets and currencies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;○**Global Depositary Receipts (GDRs),** which are receipts for shares in a foreign-based corporation traded in capital markets around the world.

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. The Fund will generally use a "replication strategy" to achieve its investment objective, meaning that it will invest in all of the component securities of the Index in approximately the same proportion as the Index. However, the Fund may also use a "representative sampling" strategy to 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,

------

**4 :: Nanotechnology ETF**![](tiny.jpg)

**PROSHARES.COM**

------

with the intent of obtaining exposure with aggregate characteristics similar to those of the Index. For example, the Fund may utilize a representative sampling strategy when the Advisor believes a replication strategy might be detrimental or disadvantageous to shareholders, such as when buying each security in an Index is impracticable or inefficient, or when there are practical difficulties or additional costs involved in replicating an Index. The Fund also may use representative sampling if the Advisor believes one or more securities in the Index becomes illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund.

Please see "Investment Objectives, Principal Investment Strategies and Related Risks" in the Fund's Prospectus for additional details.

**Principal Risks**

**You could lose money by investing in the Fund.**

&nbsp;&nbsp;&nbsp;&nbsp;●**Nanotechnology Investing Risk** — Nanotechnology is a relatively new form of technology and is subject to risks associated with a developing industry including limited product lines, markets, and financial resources as well as challenges to scalability of production. There is no guarantee that the products or services offered by companies in this business will be successful. Nanotechnology companies typically face intense competition, cyclical economic patterns, shifting consumer preferences, evolving industry standards, frequent new product introductions, evolving regulation, rapid changes in technology, loss or impairment of intellectual property rights, and potentially rapid product obsolescence. These companies may face increased scrutiny from regulators and legislators . They may be subject to scientific, technological and commercialization risks. Nanotechnology companies typically engage in significant amounts of spending on research and development. Such companies are also susceptible to operational and information security risks including those associated with hardware or software failures and security breaches.

&nbsp;&nbsp;&nbsp;&nbsp;●**Unrelated Business Lines Risk** – Companies in the Index may have significant business lines that are not nanotechnology related. These unrelated business lines may be a meaningful portion of a company's current business, in terms of profit or revenue, for example, than the portion represented by the Index theme. Consequently, these unrelated business lines may have a significant impact on the performance of the company, the Index and the Fund. In particular, these unrelated business lines may cause the Fund to underperform investments that do not have exposure to unrelated business lines. For example, if an unrelated business line of a company underperforms its nanotechnology related business line, it may negatively affect the performance of the company, the Index and the Fund.

&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;●**Equity and Market Risk** — 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.

&nbsp;&nbsp;&nbsp;&nbsp;●**Foreign Investments Risk/Emerging Markets 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.

Because the Fund's foreign investment exposure may include issuers domiciled in developing or "emerging market" countries, all the aforementioned factors are heightened. Investments in emerging markets are considered speculative.

&nbsp;&nbsp;&nbsp;&nbsp;●**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.

&nbsp;&nbsp;&nbsp;&nbsp;●**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, 2025, the Index had a significant portion of its

------

![](tiny.jpg)**Nanotechnology ETF :: 5**

**PROSHARES.COM**

------

value in issuers in the information technology industry group.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;○**Information Technology Industry Risk** — Companies in this industry may experience: intense competition, obsolescence of existing technology, and changing economic conditions and government regulation.

&nbsp;&nbsp;&nbsp;&nbsp;●**Geographic Concentration Risk** — Because the Fund focuses its investments in one or more foreign countries, an investment in the Fund may be more volatile than a more geographically diversified fund. The performance of the Fund will be affected by the political, social and economic conditions in those foreign countries and subject to the related risks. As of May 31, 2025, the Index did not have a significant portion of its value in issuers in a single country.

&nbsp;&nbsp;&nbsp;&nbsp;●**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. 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.

&nbsp;&nbsp;&nbsp;&nbsp;●**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 used by the third-party provider to identify companies whose business is nanotechnology related will achieve its intended result. Further, there can be no guarantee that the methodology underlying the Index or the daily calculation of the Index will be free from error.

&nbsp;&nbsp;&nbsp;&nbsp;●**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.

&nbsp;&nbsp;&nbsp;&nbsp;●**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.

Please see "Investment Objectives, Principal Investment Strategies and Related Risks" in the Fund's Prospectus for additional details.

*Reflects no deduction for fees, expenses or taxes. Adjusted to reflect the reinvestment of dividends 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.

Annual returns are required to be shown and should not be interpreted as suggesting that the Fund should or should not be held for longer periods of time.

**Management**

The Fund is advised by ProShare Advisors. Alexander Ilyasov, Senior Portfolio Manager, and Eric Silverthorne, Portfolio Manager, have jointly and primarily managed the Fund since September 2021 and March 2023, 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 the 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, quarterly, and capital gains, if any, at least annually.
