Risk Factors

Please see the Preliminary Offering Documents for a description of certain risks related to this investment, including, but not limited to, the following:

If your notes are not called prior to maturity, your investment may result in a loss; there is no guaranteed return of principal.

Payments on the notes, including repayment of principal, are subject to the credit risk of Barclays and to the risk of exercise of any U.K. Bail-in Power or any other resolution measure by the relevant U.K. resolution authority. If Barclays becomes insolvent, is unable to pay its obligations, or any other resolution measure is exercised, you may lose your entire investment.

The initial estimated value of the notes on the pricing date will be less than their public offering price.

If you attempt to sell the notes prior to maturity, their market value may be lower than both the public offering price and the initial estimated value of the notes on the pricing date.

If called, your return on the notes is limited to the applicable Call Premium.

You will have no rights of a holder of the securities represented by the Market Measure, and you will not be entitled to receive securities or dividends or other distributions by the issuers of those securities.

The stocks composing the Market Measure are issued by companies with small-sized market capitalization. The stock prices of small-size companies may be more volatile than stock prices of large capitalization companies. Small-size capitalization companies may be less able to withstand adverse economic, market, trade and competitive conditions relative to larger companies. Small-size capitalization companies may also be more susceptible to adverse developments related to their products or services.

Final terms will be set on the pricing date within the given range for the specified Market-Linked Investment. Please see the Preliminary Offering Documents for complete product disclosure, including related risks and tax disclosure.
