TQQQ ProShares UltraPro QQQ

ProShares, a premier provider of ETFs, announced today forward and reverse share splits on 20 of its ETFs. The splits will not change the total value of a shareholder's investment.

Forward Splits

Eight ETFs will forward split shares 3-for-1:

Ticker   ProShares ETF   Split Ratio MVV   ProShares Ultra S&P MidCap400   3:1 UYG   ProShares Ultra Financials   3:1 DDM   ProShares Ultra Dow30   3:1 EFO   ProShares Ultra MSCI EAFE   3:1 UPRO   ProShares UltraPro S&P500   3:1 EZJ   ProShares Ultra MSCI Japan   3:1 USD   ProShares Ultra Semiconductors   3:1 TQQQ   ProShares UltraPro QQQ   3:1    

All forward splits will apply to shareholders of record as of the close of the markets on May 21, 2018, payable after the close of the markets on May 23, 2018. The funds will trade at their post-split prices on May 24, 2018. The ticker symbols and CUSIP numbers for the funds will not change.

The forward splits will decrease the price per share of each fund with a proportionate increase in the number of shares outstanding. For example, for the 3-for-1 splits, every pre-split share will result in the receipt of three post-split shares, which will be priced at one-third the net asset value (“NAV”) of a pre-split share.

The following table shows the effect of a hypothetical 3-for-1 split:

Period   # of Shares Owned   Hypothetical NAV   Value of Shares Pre-Split   100   $120.00   $12,000.00 Post-Split   300   $40.00   $12,000.00      

Reverse Splits

A total of 12 ETFs will reverse split shares at the following split ratios:

All reverse splits will be effective prior to market open on May 24, 2018, when the funds will begin trading at their post-split price. The ticker symbol for the funds will not change. All funds undergoing a reverse split will be issued a new CUSIP number, listed above.

The reverse splits will increase the price per share of each fund with a proportionate decrease in the number of shares outstanding. For example, for a 1-for-4 reverse split, every four pre-split shares will result in the receipt of one post-split share, which will be priced four times higher than the NAV of a pre-split share.

Illustration of Reverse Splits

The following table shows the effects of hypothetical 1-for-5, 1-for-4 and 1-for-2 reverse splits:

Period   # of Shares Owned   Hypothetical NAV   Value of Shares Pre-Split   1,000   $10.00   $10,000.00 1:5 Post-Split   200   $50.00   $10,000.00 1:4 Post-Split   250   $40.00   $10,000.00 1:2 Post-Split   500   $20.00   $10,000.00      

Fractional Shares from Reverse Splits

For shareholders who hold quantities of shares that are not an exact multiple of the reverse split ratio (for example, not a multiple of 4 for a 1-to-4 reverse split), the reverse split will result in the creation of a fractional share. Post-reverse split fractional shares will be redeemed for cash and sent to your broker of record. This redemption may cause some shareholders to realize gains or losses, which could be a taxable event for those shareholders.

Disclosures:

ProShares is the leader in dividend growth, alternative and geared (leveraged and inverse) strategies. Source: ProShares and Strategic Insight, based on number of funds and/or assets, as of 12/31/17.

Geared (leveraged or short) ProShares ETFs seek returns that are a multiple of (e.g., 2x or -2x) the return of an index or other benchmark (target) for a single day, as measured from one NAV calculation to the next. Due to the compounding of daily returns, ProShares' returns over periods other than one day will likely differ in amount and possibly direction from the target return for the same period. These effects may be more pronounced in funds with larger or inverse multiples and in funds with volatile benchmarks. Investors should monitor their ProShares holdings consistent with their strategies, as frequently as daily. For more on correlation, leverage and other risks, please read the prospectus.

Investing involves risk, including the possible loss of principal. Geared ProShares ETFs are non-diversified, and each entails certain risks, which may include risk associated with the use of derivatives (swap agreements, futures contracts and similar instruments), imperfect benchmark correlation, leverage and market price variance, all of which can increase volatility and decrease performance. Short positions lose value as security prices increase. Narrowly focused investments typically exhibit higher volatility. Investments in smaller companies typically exhibit higher volatility. Smaller company stocks also may trade at greater spreads or lower trading volumes, and may be less liquid than stocks of larger companies. International investments may also involve risk from unfavorable fluctuations in currency values, differences in generally accepted accounting principles, and from economic or political instability. Securities focusing on a single country may be subject to higher volatility. In emerging markets, many risks are heightened, and lower trading volumes may occur. Please see summary and full prospectuses for a more complete description of risks. There is no guarantee any ProShares ETF will achieve its investment objective.

Carefully consider the investment objectives, risks, charges and expenses of ProShares before investing. This and other information can be found in their summary and full prospectuses. Read them carefully before investing. Obtain them from your financial advisor or broker-dealer representative, or visit ProShares.com.
