Description

iShares Digital Security UCITS ETF tracks the issuer-declared index: STOXX Global Digital Security Open Net Index in USD (USD). The declared annual cost (TER) is 0.40%, plus 0.04% in transaction costs estimated by the issuer in the KID. Replication is optimised physical replication (the KID declares optimisation techniques to achieve a return similar to the index); income is accumulated and reinvested in the fund. The fund has assets of about 1.7 billion euro, was launched on 7 September 2018 and is domiciled in Ireland.

The fund’s objective — in the issuer’s words

The Fund which aims to achieve a return on your investment, through a combination of capital growth and income on the Fund’s assets, which reflects the return of the STOXX Global Digital Security Index, (the Index). The Fund is passively managed, and aims to invest in equity securities (e.g. shares) that make up the Index. The Index reflects the performance of a sub-set of global equity securities of eligible countries within the STOXX Global Total Market Index (the “Parent Index”) which derive significant revenues from the provision of cyber security focused solutions providing exposure to those companies globally focused on the transmission, safeguarding and/or handling of sensitive data and/or access to data centres. Further details regarding the Index (including the methodology and its constituents) are available on the index provider’s website at https:// www.stoxx.com/indices. The Fund’s investment in securities that make up the Index will, at the time of purchase, comply with the credit or ESG requirements of the Index. Where securities no longer meet such requirements, the Fund may continue to hold them until they cease to form part of the Index and it is practicable to sell them. The Fund may obtain indirect exposure (for example, through financial derivative instruments (“FDIs”) (i.e. investments the prices of which are based on one or more underlying assets) and units in collective investment schemes) to securities considered not to satisfy these ESG criteria. The Index may include small, mid and/or large capitalisation constituents of the Parent Index from both developed and emerging market countries globally. Each constituent of the Index is adjusted equally weighted at each Index rebalance. The Fund uses optimising techniques to achieve a similar return to its Index. These techniques may include the strategic selection of certain securities that make up the Index or other securities which provide similar performance to certain constituent securities. These may also include the use of FDIs, which may be used for direct investment purposes. The price of equity securities fluctuates daily and may be influenced by factors affecting the performance of the individual companies issuing the equities, as well as by daily stock market movements, and broader economic and political developments which in turn may affect the value of your investment. The relationship between the return on your investment, how it is impacted and the period for which you hold your investment is considered below (see “How long should I hold it and can I take my money out early?”).

The depositary of the Fund is State Street Custodial Services (Ireland) Limited. Further information about the Fund can be obtained from the latest annual report and half-yearly reports of the iShares IV plc. These documents are available free of charge in English and certain other languages. These can be found, along with other (practical) information, including prices of units, on the iShares website at: www.ishares.com or by calling +49 89427295800 or from your broker or financial adviser.

Your shares will be accumulating shares (i.e. income will be included in their value). Your shares will be denominated in US Dollar, the Fund's base currency. The shares are listed and traded on various stock exchanges. In normal circumstances, only authorised participants may buy and sell shares directly with the Fund. Investors who are not authorised participants (e.g. select financial institutions) can generally only buy or sell the shares on the secondary market (e.g. via a broker on a stock exchange) at the then prevailing market price. The value of the shares are related to the value of the underlying assets of the Fund, less costs (see “What are the costs?” below). The prevailing market price at which the shares trade on the secondary market may deviate from the value of the Shares. Indicative net asset value is published on relevant stock exchanges websites.

Intended retail investor:The Fund is intended for retail investors with the ability to bear losses up to the amount invested in the Fund (see “How long should I hold it and can I take my money out early?”).

Insurance benefits:The Fund does not offer any insurance benefits.

Source: iShares. Issuer-declared historical series; inflation: Eurostat and national statistical institutes, latest available July 2026 — for later days the index stays at the last published value (institutes publish with a few weeks’ lag). The «adjusted for inflation» view expresses value in today’s purchasing power for the selected country; volatility always stays nominal, as elsewhere on the site (deflating it would add artificial swings caused by the monthly cadence of the price index). Past performance is not indicative of future results: these are facts, not a recommendation.

Tracking difference — fund vs index

How much the fund returned above (+) or below (−) its index, year by year. It measures the actual deviation: the combined effect of costs (TER and transaction), securities-lending revenue and replication optimisations — which is why it can beat the TER. Tracking difference was positive in 1 of the last 7 calendar years: a past observation, not an indication of future outperformance.
