BIB ProShares Ultra NASDAQ Biotechnology

ProShares, a premier provider of alternative ETFs, announced today forward and reverse share splits on 21 of its ETFs. The splits will not change the value of a shareholder’s investment.

Forward Splits

Twelve ETFs will forward split shares 2-for-1:

              Ticker     ProShares ETF     Split Ratio CSM     Large Cap Core Plus     2:1 SAA     Ultra SmallCap600     2:1 UMDD     UltraPro MidCap400     2:1 SSO     Ultra S&P500     2:1 UPRO     UltraPro S&P500     2:1 DDM     Ultra Dow30     2:1 UDOW     UltraPro Dow30     2:1 RXL     Ultra Health Care     2:1 QLD     Ultra QQQ     2:1 UYG     Ultra Financials     2:1 ROM     Ultra Technology     2:1 BIB     Ultra Nasdaq Biotechnology     2:1        

All splits will apply to shareholders of record as of the close of the markets on May 18, 2015, payable after the close of the markets on May 19, 2015. The funds will trade at their post-split price on May 20, 2015. The ticker symbol and CUSIP numbers for the funds will not change.

The splits will decrease the price per share of each fund with a proportionate increase in the number of shares outstanding. For example, for the 2-for-1 splits, every pre-split share will result in the receipt of two post-split shares, which will be priced at half the net asset value (“NAV”) of a pre-split share.

The following table shows the effect of a hypothetical 2-for-1 split:

                    Period     # of Shares Owned     Hypothetical NAV     Value of Shares Pre-Split     100     $100.00     $10,000.00 Post-Split     200     $50.00     $10,000.00            

Reverse Splits

Nine ETFs will reverse split shares at the following split ratios:

                          Ticker     ProShares ETF     Split Ratio     Old CUSIP     New CUSIP SRS     UltraShort Real Estate     1:4     74348A871     74348A244 SCC     UltraShort Consumer Services     1:4     74348A616     74348A236 RXD     UltraShort Health Care     1:4     74347B102     74348A228 RWM     Short Russell2000     1:4     74347R826     74348A210 BOIL     Ultra Bloomberg Natural Gas     1:4     74347W122     74347W296 UCD     Ultra Bloomberg Commodity     1:4     74347W106     74347W288 YCL     Ultra Yen     1:4     74347W866     74347W270 UVXY     Ultra VIX Short-Term Futures     1:5     74347W346     74347W312 UCO     Ultra Bloomberg Crude Oil     1:5     74347W650     74347W320                

All reverse splits will be effective at the market open on May 20, 2015, 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 a Reverse Split

The following table shows the effect of a hypothetical 1-for-4 reverse split:

                    Period     # of Shares Owned     Hypothetical NAV     Value of Shares Pre-Split     1,000     $10.00     $10,000.00 Post-Split     250     $40.00     $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.

About ProShares

ProShares offers the nation's largest lineup of alternative ETFs. We help investors to go beyond the limitations of conventional investing and face today's market challenges. ProShares helps investors build better portfolios by providing access to alternative investments delivered with the liquidity, transparency and cost effectiveness of ETFs. Our wide array of alternative ETFs can help you reduce volatility, manage risk and enhance returns.

ProShares has the largest lineup of alternative ETFs in the United States according to Strategic Insight, based on analysis of all the known alternative ETF providers (as defined by Strategic Insight) by their number of funds and assets (as of 1/31/2015).

Geared (Short or Ultra) ProShares ETFs seek returns that are either 3x, 2x, -1x, -2x or -3x 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. ProShares ETFs are generally 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. Leverage can increase market exposure and magnify investment risk. Narrowly focused investments and investments in smaller companies typically exhibit higher volatility. There are additional risks related to commodity investments due to large institutional purchases or sales, and natural and technological factors such as severe weather, unusual climate change, and development and depletions of alternative resources. There are additional risks due to debt levels in the underlying countries, inflation and interest rates, investment activity, and global political and economic concerns. Certain derivative instruments will subject the fund to counterparty risk and credit risk, which could result in significant losses for the fund. Please see their summary and full prospectuses for a more complete description of risks. There is no guarantee any ProShares ETF will achieve its investment objective.

Investing in ETFs involves a substantial risk of loss. BOIL, UCD, YCL, UVXY and UCO are not investment companies regulated under the Investment Company Act of 1940 and are not afforded its protections. Please read the prospectus carefully before investing. These ETFs generate a K-1 tax form. UVXY invests in futures. VIX futures are among the most volatile futures contracts. A fund's exposure to its index may subject that fund to greater volatility than investments in traditional securities, which may adversely affect an investor's investment in that fund. VIX futures indexes are mean reverting; funds benchmarked to them should not be expected to appreciate over extended periods. Due to defined time periods and other features, VIX futures indexes and funds benchmarked to them can be expected to perform differently than the VIX. These ETFs are not suitable for all investors.
