composition is subject to change. 1 The investor fee is equal to the Yearly Fee times the principal amount of your securities times the index factor, calculated on a daily basis in the following manner: The investor fee on the inception date will
equal zero. On each subsequent calendar day until maturity or early redemption, the investor fee will increase by an amount equal to the Yearly Fee times the principal amount of your securities times the index factor on that day (or, if such day is
not a trading day, the index factor on the immediately preceding trading day) divided by 365. The index factor on any given day will be equal to the closing value of the index on that day divided by the initial index level. The initial index level
is the closing value of the index on the inception date of the securities. Page 1 of 3

annual period are likely to differ from average annualized returns. Because the Standard Deviation % Annualized is based on historical data, it may not predict variability in annualized performance of the ETNs in the future. Source: BlackRock,

while the correlation coefficient will be zero when returns on two assets are completely independent. Source: BlackRock, Barclays Selected Risk Considerations An investment in the iPath ETNs described herein (the ETNs) involves risks.
Selected risks are summarized here, but we urge you to read the more detailed explanation of risks described under Risk Factors in the applicable prospectus supplement and pricing supplement. You May Lose Some or All of Your Principal:
The ETNs are exposed to any decrease in the level of the underlying index between the inception date and the applicable valuation date. Additionally, if the level of the underlying index is insufficient to offset the negative effect of the investor
fee and other applicable costs, you will lose some or all of your investment at maturity or upon redemption, even if the value of such index has increased. Because the ETNs are subject to an investor fee and any other applicable costs, the return on
the ETNs will always be lower than the total return on a direct investment in the index components. The ETNs are riskier than ordinary unsecured debt securities and have no principal protection. Credit of Barclays Bank PLC: The ETNs are unsecured
debt obligations of the issuer, Barclays Bank PLC, and are not, either directly or indirectly, an obligation of or guaranteed by any third party. Any payment to be made on the ETNs, including any payment at maturity or upon redemption, depends on
the ability of Barclays Bank PLC to satisfy its obligations as they come due. As a result, the actual and perceived creditworthiness of Barclays Bank PLC will affect the market value, if any, of the ETNs prior to maturity or redemption. In addition,
in the event Barclays Bank PLC were to default on its obligations, you may not receive any amounts owed to you under the terms of the ETNs. Issuer Redemption: If specified in the applicable prospectus, Barclays Bank PLC will have the right to redeem
or call a series of ETNs (in whole but not in part) at its sole discretion and without your consent on any trading day on or after the inception date until and including maturity. Barclays Pure Beta Series 2 Methodology: The Barclays
Pure Beta Series 2 Methodology seeks to mitigate distortions in the commodities markets associated with investment flows and supply and demand distortions. However, there is no guarantee that the Pure Beta Series 2 Methodology will succeed in these
objectives and an investment in the ETNs linked to indices using this methodology may underperform compared to an investment in a traditional commodity index linked to the same commodities. Market and Volatility Risk: The prices of physical
commodities, including the commodities underlying the index components, can fluctuate widely due to I0912 supply and demand disruptions in major producing or consuming regions. Additionally, the market value of the ETNs may be influenced by
manyCUPM unpredictable factors including changes in supply and demand relationships, governmental policies and economic events.iP Page 2 of 3

No principal protection Ability to execute tactical views Credit risk of the issuer Interest Rate Management Concentration of index exposure Hedging Tool Minimum redemption value directly with issuer
Exchange listed Market risk Daily redemption capabilities directly to issuer Yearly fee and applicable costs No tracking error to their specified underlying index** * Diversification does not protect against market risk.
** Excluding fees and applicable costs and applies only to the indicative value, not necessarily to the secondary market price. Tracking error refers to the under/over performance differential of an ETN versus its underlying index over a given time
period, after accounting for the ETNs fees and costs. One cannot invest directly in an index. Concentration Risk: Because the ETNs are linked to an index composed of futures contracts on a single commodity or in only one commodity sector, the
ETNs are less diversified than other funds. The ETNs can therefore experience greater volatility than other funds or investments. A Trading Market for the ETNs May Not Develop: Although the ETNs are listed on NYSE Arca, a trading market for the ETNs
may not develop and the liquidity of the ETNs may be limited, as we are not required to maintain any listing of the ETNs. No Interest Payments from the ETNs: You may not receive any interest payments on the ETNs. Restrictions on the Minimum Number
of ETNs and Date Restrictions for Redemptions: You must redeem at least 50,000 ETNs of the same series at one time in order to exercise your right to redeem your ETNs on any redemption date. You may only redeem your ETNs on a redemption date if we
receive a notice of redemption from you by certain dates and times as set forth in the pricing supplement. Uncertain Tax Treatment: Significant aspects of the tax treatment of the ETNs are uncertain. You should consult your own tax advisor about
your own tax situation. Barclays Bank PLC has filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates. Before you invest, you should read the prospectus and other documents Barclays
