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:

Depending on the performance of the Market Measure as measured shortly before the maturity date, your investment may result in a loss; there is no guaranteed return of principal.

Your return on the notes may be less than the yield you could earn by owning a conventional fixed or floating rate debt security of comparable maturity.

Your investment return is limited to the return represented by the Capped Value and may be less than a comparable investment directly in the securities included in the Market Measure.

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 is expected to be lower 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.

A trading market is not expected to develop for the notes.

Our business, hedging and trading activities, and those of MLPF&S, BofAS and our respective affiliates (including trades in the securities included in the Market Measure), and any hedging and trading activities we, MLPF&S, BofAS or our respective affiliates engage in for our clients’ accounts, may affect the market value and return of the notes and may create conflicts of interest with you.

There may be potential conflicts of interest involving the calculation agents, which are Barclays and BofAS.

The Market Measure sponsor may adjust the Market Measure in a way that affects its level, and has no obligation to consider your interests.

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

While we, MLPF&S, BofAS or our respective affiliates may from time to time own the securities included in the Market Measure, we, MLPF&S, BofAS and our respective affiliates do not control the issuers of those securities, and have not verified any disclosure made by any other company.

The U.S. federal income tax consequences of an investment in the notes are uncertain.

The notes are subject to small-capitalization companies risk with respect to the Market Measure.

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.
