Risks Associated with the HSBC 3D Advantage Index (the “ADV3D Index”) • The strategy tracked by the ADV3D Index and the views implicit in the ADV3D Index are not guaranteed to succeed. • The momentum strategy employed by the ADV3D Index may cause it to underperform the HSIE3EDG Index. • The HSIE3EDG Index may underperform the Base Index. • Embedded fees and costs, including embedded fees and costs associated with the HSIE3EDG Index and the Base Index, will reduce the performance of the ADV3D Index. • The HSIE3EDG Index may not approximate its target volatility. • Historical volatility may be a poor indicator of future volatility. • The volatility control mechanism may negatively impact the performance of the HSIE3EDG Index and thereby negatively impact the performance of the ADV3D Index. • There can be no guarantee that the method by which volatility is determined will be effective; exponentially weighted moving averages place greater emphasis on more recent levels. • The Momentum Signals employed by the ADV3D Index and the Signals employed by the Underlying Indices may be less accurate or result in less favorable performance that other alternatives. • The weighting between the Equity Sub-Index and the Treasury Sub-Index may not be suitable for all market conditions or objectives; the weighting may diverge significantly between rebalancings. • The lower performance of one Sub-Index may offset increases in the other Sub-Index. • No ownership rights in any bonds or component stocks or any rights in any bond futures contracts or equity index futures contracts. • Structured product investments linked to the ADV3D Index do not offer direct exposure to the performance of U.S. equities or U.S. Treasury bonds. • Higher futures prices of the futures contracts underlying the indices tracked by the Underlying Indices relative to the current prices of those contracts may affect the level of the indices and, therefore, the value of the Underlying Indices, Base Index, the HSIE3EDG Index and the ADV3D Index and the value of any structured product investment linked to the ADV3D Index. • The Underlying Indices are excess return indices, not total return indices. • Suspension or disruptions of market trading in futures contracts may adversely affect the value of any structured product investment linked to the ADV3D Index. • HSBC may adjust the ADV3D Index, the HSIE3EDG Index or the Base Index in ways that adversely affect holder’s interests in any structured product investment linked to the ADV3D Index. • Each of the ADV3D Index, HSIE3EDG Index, the Base Index and the Underlying Indices were recently launched and have limited operating history. • MerQube administers, calculates and publishes the ADV3D Index, the HSIE3EDG Index and the Base Index and sponsors, administers, calculates and publishes the Underlying Indices.

Use of Simulated Returns The ADV3D Index was launched on February 19, 2026 and each of the HSIE3EDG Index, the Base Index and each Underlying Index was launched on November 8, 2024 and therefore each has limited historical performance. As a result, limited actual historical performance information is available for you to consider in making an independent investigation of the ADV3D Index, which may make it difficult for you to evaluate the historical performance of the ADV3D Index and make an informed investment decision than would be the case if the ADV3D Index, the HSIE3EDG Index, the Base Index and each Underlying Index had a longer trading history. Hypothetical back-tested performance prior to the respective launch of the ADV3D Index, HSIE3EDG Index, the Base Index and each Underlying Index provided in this brochure refers to simulated performance data created by applying each of the ADV3D Index, HSIE3EDG Index, the Base Index and each Underlying Index’s calculation methodologies to historical prices of the underlying constituents. Such simulated performance data has been produced by the retroactive application of a back-tested methodology in hindsight, and may give more preference towards underlying constituents that have performed well in the past. Hypothetical back-tested results are neither an indicator nor a guarantor of future results. The hypothetical back-tested performance of the ADV3D Index prior to February 19, 2026 cannot fully reflect the actual results that would have occurred had the ADV3D Index actually been calculated during that period, and should not be relied upon as an indication of the ADV3D Index’s future performance. Because of the lack of actual historical performance data, your investment in any structured investment linked to the ADV3D Index may involve a greater risk than investing in a security or other instrument linked to one or more indices with an established record of performance.
