Issuer: Barclays Bank PLC

Tenor: Approximately 5 years

Reference Asset: The Barclays US Tech Accelerator 6% Decrement USD ER Index (Bloomberg ticker symbol “BXIIUT4E<Index>”) (the “Underlier” or the “Index”). The Index attempts to provide variable exposure of up to 400% to the Barclays US Tech Tracker ER Index (the “Futures Index”), with greater exposure when the realized volatility of the Futures Index is relatively lower (subject to the maximum exposure of 400%) and lesser exposure when the realized volatility of the Futures Index is relatively higher (subject to a minimum exposure of 100%). The Futures Index tracks the excess return of a notional rolling position in the first nearby futures contract on the Nasdaq-100 Index^® (the “Reference Index”). Please see “Information Regarding the Underlier” in the accompanying Pricing Supplement for more information on the Index and its calculation, composition and methodology.

Buffer Percentage: 20.00%

Buffer Value: 80.00% of the Initial Underlier Value

Redemption Premium:
The Redemption Premium applicable to each Observation Date is a percentage that increases for each Observation Date based on a simple (non-compounding) return of approximately 19.00% per annum.

Any positive return on the Notes will not exceed the Redemption Premium with respect to the applicable Observation Date, and your return will not be based on the amount of any appreciation in the value of the Underlier, which may be significant.

Index Deductions: The Underlier is subject to a 6% per annum decrement, deducted daily. The decrement will offset appreciation of the Futures Index, which is the Underlier’s underlying index, heighten depreciation of the Futures Index and generally act as a drag on the performance of the Index. The Index will trail the performance of an identical index without a decrement. In addition, the Futures Index is subject to an implicit financing cost, which will negatively affect the performance of the Futures Index, and is likely to underperform the Reference Index during periods of high market interest rates. Please see “Information Regarding the Underlier,” “Selected Risk Considerations—Risks Relating to the Underlier Generally—The Value of the Index Will Reflect a 6% per Annum Decrement, Deducted Daily” and “Selected Risk Considerations—Risks Relating to the Futures Index—The Performance of the Futures Index Will Differ from the Performance of the Reference Index” in the accompanying Pricing Supplement for more information on the Index deductions.

Selected Structure Definitions

Automatic Redemption:
The Notes will not be automatically redeemable for approximately the first year after the Issue Date. If, on any Observation Date, the Closing Value of the Underlier is greater than or equal to the Initial Underlier Value, the Notes will be automatically redeemed and you will receive on the relevant Redemption Settlement Date a cash payment per $1,000 principal amount Note that will provide a return equal to the applicable Redemption Premium, calculated as follows:

$1,000 + ($1,000 × applicable Redemption Premium)

No further amounts will be payable on the Notes after they have been automatically redeemed.

Payment at Maturity:
If the Notes are not automatically redeemed, you will receive on the Maturity Date a cash payment per $1,000 principal amount Note determined as follows:

§ If the Final Underlier Value is greater than or equal to the Buffer Value, you will receive a payment of $1,000 per $1,000 principal amount Note

§ If the Final Underlier Value is less than the Buffer Value, you will receive an amount per $1,000 principal amount Note calculated as follows:

$1,000 + [$1,000 × (Underlier Return + Buffer Percentage)]

If the Notes are not automatically redeemed and the Final Underlier Value is less than the Buffer Value, your Notes will be exposed to the decline of the Underlier in excess of the Buffer Percentage from the Initial Underlier Value and you will lose up to 80.00% of your investment at maturity.

Underlier Return: (Final Underlier Value – Initial Underlier Value) / Initial Underlier Value
