The Underlyings
The Fund is an exchange-traded fund of iShares® Trust, a registered investment company, that seeks to track the investment results,
before fees and expenses, of an index composed of U.S.-listed equities in the semiconductor sector, which we refer to as the
Underlying Index with respect to the Fund. The Underlying Index with respect to the Fund is currently the NYSE Semiconductor Index.
The NYSE Semiconductor Index is a modified float-adjusted market capitalization-weighted index that is designed to track the
performance of the thirty largest qualifying U.S.-listed companies classified according to the ICE Uniform Sector Classification schema
within the semiconductors industry. For additional information about the Fund, see "Fund Descriptions - The iShares® ETFs" in the
accompanying underlying supplement.
The Index is a modified market capitalization-weighted index that is designed to measure the performance of 100 of the largest non-
financial companies listed on The Nasdaq Stock Market. For additional information about the Index, see "Equity Index Descriptions -
The Nasdaq-100 Index®" in the accompanying underlying supplement, as supplemented by the following updated information.
Nasdaq, Inc. ("Nasdaq"), the index sponsor of the Index, recently implemented several changes to the methodology of the Index,
including changes to the determination of market capitalization for purposes of constituent selection and weighting, the introduction of
an expedited "Fast Entry" process for certain large companies, the removal of the minimum free float requirement for constituent
selection and the introduction of a cap on the share count used to determine the weighting of low-float securities. These changes
became effective on May 1, 2026, with certain constituent and rebalancing adjustments first implemented during the June 2026
quarterly review. The information set forth below supersedes the information regarding the Index included in the accompanying
underlying supplement to the extent inconsistent therewith.
Under the updated methodology, Nasdaq uses different measures of market capitalization for constituent selection and constituent
weighting. For purposes of constituent selection, Nasdaq now uses "Full Market Capitalization." For companies with direct (non-ADR)
listings and companies represented by an American depositary receipt ("ADR") that serves as a company's primary global listing (a
"Primary ADR"), Full Market Capitalization includes both listed and unlisted shares. For companies represented by an ADR where the
underlying shares serve as the company's primary global listing and are listed on a foreign exchange (a "Non-Primary ADR"), Full
Market Capitalization is based solely on the value of the listed depositary shares, and foreign-listed underlying shares and unlisted
shares are excluded. For purposes of constituent weighting, Nasdaq uses "Modified Market Capitalization," which takes into account
only eligible listed share classes and disregards foreign-listed and unlisted shares.
In addition, the updated methodology eliminates the minimum free float requirement for inclusion in the Index, although the Modified
Market Capitalization used for constituent weighting imposes a limitation on the weightings of low-float securities. Specifically, for
purposes of determining Modified Market Capitalization, each low-float security's share count is limited to the lesser of (i) its reported
total shares outstanding ("TSO") (or, in the case of an ADR, its listed ADR shares outstanding), and (ii) three times its free-floating
shares or free-floating ADR shares, as applicable. Other than as a direct result of corporate actions, the Index also no longer
implements ad-hoc intra-quarter adjustments to a security's TSO between scheduled rebalancing events.
The updated methodology also introduces a "Fast Entry" process under which newly eligible securities, including both initial public
offerings and companies that have recently transferred their listing to an eligible exchange, may be added to the Index on an expedited
basis if their Full Market Capitalization would rank within the top 40 current index constituents and they satisfy the applicable eligibility
criteria. A Fast Entry inclusion will not require the removal of an existing constituent and may temporarily increase the number of
constituents in the Index above 100.
The updated methodology further provides for quarterly rebalances in March, June and September. During quarterly rebalances, the
index shares of each constituent are adjusted for changes in TSO, index shares of low-float securities are adjusted to reflect changes in
float, constituents ranked outside the top 125 by Full Market Capitalization are removed and, if necessary, replaced, and certain
additional companies whose Full Market Capitalization ranks within the top 40 of current index constituents may be added without
requiring a corresponding removal. Securities added to the Index between annual reconstitutions, including through the Fast Entry
process, as intra-quarter replacements or as part of a March, June or September quarterly rebalance, will have their initial index
weightings determined using a linear interpolation process based on their Modified Market Capitalization ranking.
