| ![](gkwvsckx0vyc000001.jpg) | **GS Finance Corp.**<br> Medium-Term Notes, Series F<br> guaranteed by<br> The Goldman Sachs Group, Inc.<br> **BlackRock<sup>®</sup> Dynamic Factor Index Supplement No. 39**<br> **Notes Linked to the Performance of the BlackRock<sup>®</sup> Dynamic Factor Index** |

---

GS Finance Corp. may from time to time offer and sell notes, the payments and performance of which will be linked to the BlackRock<sup>®</sup> Dynamic Factor Index (the "index"). The index measures the extent to which the performance of the combination of an equity ETF basket composed of up to five equity ETFs, a fixed income ETF basket composed of up to three fixed income ETFs and a cash constituent (together with the ETFs, the underlying assets) outperforms the sum of the return on (i) the Secured Overnight Financing Rate (SOFR) plus 0.26161% plus (ii) an additional 0.65% per annum fee (accruing daily). The weights of the ETFs within the equity ETF basket are determined based on three common economic measures (factors) – "economic regime", "value" and "momentum", while the weights of the ETFs within the fixed income ETF basket are determined based on how medium-term interest rates are trending. The relative weights of the equity ETF basket, the fixed income ETF basket and the cash constituent that compose the index are determined based on measures of volatility using the past returns of the ETFs (i.e., the degree of variation in past returns given the various weightings of these components). The equity ETF basket rebalances monthly and the fixed income ETF basket rebalances on each index business day. Allocations of the index among the equity ETF basket, the fixed income ETF basket and the cash constituent are determined on each index business day with a goal of limiting volatility (i.e., the degree of variation in the past returns) to no more than 5%.

**As a result of such allocations, the index may include limited exposure to the ETFs and may allocate a significant portion of its exposure to the cash constituent, the return on which will be less than the *sum* of the return on (i) SOFR *plus* 0.26161% *plus* (ii) 0.65% per annum. In the recent past, a very significant portion (up to 85.5%) of the index has been allocated to the cash constituent. The greater the percentage of the index allocated to the cash constituent, the higher the return that will be required on the ETFs in order to have a return on your investment.** 

**Because the index measures the performance of the selected underlying assets less the sum of the return on (i) SOFR plus 0.26161% plus (ii) 0.65% per annum (accruing daily), on any day such underlying assets must outperform the return on (i) SOFR plus 0.26161% plus (ii) 0.65% per annum for the index level to increase.** 

**Prior to December 28, 2021, the index measured the extent to which the performance of the combination of the underlying assets outperformed the sum of the return on 3-month USD LIBOR plus an additional 0.65% per annum fee (accruing daily). Further, prior to such date, the cash constituent reflected notional returns accruing to a hypothetical investor from an investment in a notional money market account that accrued interest at 3-month USD LIBOR, which return was less than the return on the sum of 3-month USD LIBOR plus 0.65% per annum. As a result, extremely limited historical information regarding the performance of the index subsequent to its discontinued use of 3-month USD LIBOR is available, which may make it difficult for you to make an informed decision with respect to an investment in the notes.**

The accompanying prospectus and the accompanying prospectus supplement, each as may be amended from time to time, that form a part of Registration Statement No. 333-269296, describes some of the terms that may apply generally to the notes, including any notes you purchase.

#### SUMMARY OVERVIEW OF THE INDEX
*Please note that this section constitutes only a brief overview of the index. The index will be described in more detail in the applicable pricing supplement. You should not invest in the notes without also reading the applicable pricing supplement in full, including the sections entitled "The Index" and "Additional Risk Factors Specific to Your Notes" (including risks and considerations relating to the index, the particular notes being offered thereby and certain other matters). Neither this section, the section entitled "Additional Risks Factors Specific to the ETFs" nor any other information in this index supplement is intended to be a substitute for the information relating to the index, including the risk factors relating to the index, set forth in the applicable pricing supplement.*<br>

The BlackRock<sup>®</sup> Dynamic Factor Index (the index) measures the extent to which the performance of the combination of an equity ETF basket composed of five equity ETFs, a fixed income ETF basket composed of three fixed income ETFs and a cash constituent (together with the ETFs, the underlying assets) outperforms the sum of the return on a notional interest rate (SOFR *plus* 0.26161%) *plus* 0.65% per annum (accruing daily). The weights of the ETFs within the equity ETF basket are determined based on three common economic measures (factors) — "economic regime", "value" and "momentum", while the weights of the ETFs and within the fixed income ETF basket are determined based on how medium-term interest rates are trending. The relative weights of the equity ETF basket, the fixed income ETF basket and the cash constituent that compose the index are determined based on measures of volatility using the past returns of the ETFs (i.e., the degree of variation in past returns given the various weightings of these components).

**Prior to December 28, 2021, the index measured the extent to which the performance of the combination of the underlying assets outperformed the sum of the return on 3-month USD LIBOR plus an additional 0.65% per annum fee (accruing daily). Further, prior to such date, the cash constituent reflected notional returns accruing to a hypothetical investor from an investment in a notional money market account that accrued interest at 3-month USD LIBOR, which return was less than the return on the sum of 3-month USD LIBOR plus 0.65% per annum. As a result, extremely limited historical information regarding the performance of the index subsequent to its discontinued use of 3-month USD LIBOR is available, which may make it difficult for you to make an informed decision with respect to an investment in the notes.**

The following is a summary of the index components:

• An equity ETF basket with components that are weighted to provide exposure to three common economic measures (factors) — "economic regime", "value" (which is composed of a "cash flow from operations to price" signal and a "forward earnings yield" signal) and "momentum". For purposes of calculating the index, a signal is a measurement of a specified economic measure that is used to determine the components of the equity and fixed income ETF baskets. Each month, the allocation to the five equity ETFs in the equity ETF basket is rebalanced based primarily on the characteristics of each equity ETF as measured by each of the three common factors and the volatility of the returns of each equity ETF. The five equity ETFs are as follows:

o *iShares <sup>®</sup> MSCI USA Momentum Factor ETF (MTUM);* 

o *iShares <sup>®</sup> MSCI USA Size Factor ETF (SIZE);* 

o *iShares <sup>®</sup> MSCI USA Quality Factor ETF (QUAL);* 

o *iShares <sup>®</sup> MSCI USA Value Factor ETF (VLUE); and* 

o *iShares <sup>®</sup> MSCI USA Min Vol Factor ETF (USMV).* 

• A fixed income ETF basket with components that are weighted based on a rates momentum signal which measures how medium-term interest rates are trending. On each index index business day, the allocation to the fixed income ETFs in the fixed income ETF basket is rebalanced, with 50% allocated to the iShares<sup>®</sup> 7-10 Year Treasury Bond ETF and the remaining 50% allocated to one of the other fixed income ETFs (other than during periods when a transition is being effected between the iShares<sup>®</sup> 1-3 Year Treasury Bond ETF and the iShares<sup>®</sup><sup></sup>20+ Year Treasury Bond ETF). The three fixed income ETFs are as follows:

o *iShares <sup>®</sup> 1-3 Year Treasury Bond ETF (SHY);* 

o *iShares <sup>®</sup> 7-10 Year Treasury Bond ETF (IEF); and* 

o *iShares <sup>®</sup> 20+ Year Treasury Bond ETF (TLT).* 

• A cash constituent that reflects the notional returns accruing to a hypothetical investor from an investment in a notional money market account that accrues interest at SOFR *plus* 0.26161%, calculated in accordance with the Act/360 day count convention (i.e., using the actual number of days in the relevant accrual period divided by 360).

Allocations of the index among the equity ETF basket, the fixed income ETF basket and the cash constituent are determined on each index business day according to the following volatility control procedures:

------

• First, to the extent that the volatility (i.e., the degree of variation in the past returns) of the equity ETF basket exceeds the target volatility of 5%, the fixed income ETF basket is assigned a positive weight, and the weight of the equity ETF basket is reduced by the amount needed to achieve the 5% volatility target. For purposes of calculating volatility in this portion of the volatility control procedures, the volatility contribution of the fixed income ETF basket is not taken into account.

• Second, to the extent that the historically realized volatility of a weighted four asset portfolio consisting of the equity ETF basket and the three fixed income ETFs exceeds the 5% volatility target, the index will make an allocation to the cash constituent, and the weights of the equity ETF basket and fixed income ETFs will be ratably reduced.

How the volatilities used to make allocations of the index among its components are calculated, including over what time periods historical data is employed and the method of calculation, is described in greater detail below.

For the purpose of the index:

• an "underlying asset" is one of the ETFs or the cash constituent that is eligible for inclusion in the index on an index business day;

• an "ETF" is one of the ETFs that is eligible for inclusion in the index on an index business day; and

• an "index business day" is a day on which the New York Stock Exchange is open for regular trading.

BlackRock Index Services, LLC ("Index Services" or the "index administrator"), a subsidiary of BlackRock, Inc., designs, sponsors, calculates, administers and publishes the index.

#### Underlying Asset Weightings
As of March 13, 2023, the following chart sets forth the weighting of each underlying asset and the hypothetical and historical average percentage weightings of the underlying assets, the highest percentage weightings of the underlying assets and the percentage of index business days with positive weightings for the underlying assets from January 1, 2018 to March 13, 2023. The chart uses historical information from October 31, 2019 (the index launch date) to March 13, 2023 and hypothetical data from January 1, 2018 to October 31, 2019. The hypothetical data is based on the historical levels of the underlying assets and uses the same methodology that is used to calculate the index. As a result, the following chart does not reflect the global financial crisis which began in 2008, which had a materially negative impact on certain of the underlying assets. **You should not take the historical information or hypothetical data as an indication of the future performance of the index.**

#### Additional Risk Factors Specific to the ETFs
&nbsp;&nbsp; ***The following risks relate only to the ETFs underlying the index. For risks and considerations relating to the index itself and certain other matters, see the applicable pricing supplement. You should carefully review all of the risks and considerations herein and in the applicable pricing supplement, the applicable product supplement, if any, the accompanying prospectus supplement and the accompanying prospectus.***<br> *An investment in your notes is subject to the risks described below as well as the risks and considerations described in the applicable pricing supplement, the applicable product supplement, if any, the accompanying prospectus supplement and the accompanying prospectus. Your notes are a riskier investment than ordinary debt securities. Also, your notes are not equivalent to investing directly in any underlying asset or the assets held by any ETF or in notes that bear interest at the notional interest rate. You should carefully consider whether the offered notes are appropriate given your particular circumstances.* <br>

#### Risks related to all of the ETFs

#### The ETFs Are Passively Managed to Track an Index and May Not Perform as Well as an Actively Managed Fund or Another Investment
The ETFs are not actively managed and may be affected by a general decline in the assets tracked by their underlying indices. Each passively managed ETF invests in assets included in, or representative of, the underlying index. These ETFs' investment advisors do not attempt to take defensive positions under any market conditions, including during declining markets. This means, among other things, that the investment advisor typically will not sell a particular holding just because it is performing poorly. Instead, the ETF seeks to track the index regardless of whether the index level is increasing or decreasing. As a result, shares of the passively managed ETFs may not perform as well as an investment in actively managed ETFs or a basket comprised solely of actively managed ETFs or some other investment that seeks to outperform a benchmark or market.

#### There is No Affiliation Between Us and Any Issuer of Assets Held by Any ETF or Any Sponsor of Any ETF
GS&Co. and one or more of our other affiliates may act, from time to time, as authorized participants in the distribution of shares of ETFs, and, at any time, may hold shares of ETFs. We are not affiliated with the issuers of the assets held by the ETFs, the underlying index sponsors or the ETF sponsors or investment advisors. However, our affiliates may currently or from time to time in the future own securities of, or engage in business with, the ETFs, their sponsors, their investment advisors, the sponsors of the underlying indexes or the issuers of assets held by the ETFs. Nevertheless, neither we nor any of our affiliates has verified the accuracy or the completeness of any information about the ETFs, the investment advisors or the issuers of assets held by the ETFs, and we have consulted only publicly available sources of information about them. You, as an investor in the notes, should make your own investigation into the ETFs, the investment advisors and the issuers of the assets held by the ETFs. See "The Underlying Assets" below for additional information about the ETFs.

None of the ETF sponsors, the sponsors of the underlying indexes, the ETFs' investment advisors and the issuers of assets held by the ETFs are involved in the offering of your notes in any way and none of them have any obligation of any sort with respect to your notes. Thus, none of the ETF sponsors, the sponsors of the underlying indexes, the ETFs' investment advisors and the issuers of assets held by the ETFs have any obligation to take your interests into consideration for any reason, including in taking any corporate actions that might adversely affect the level of an index or making any investment decision for the ETFs.

**The Policies of the ETF Sponsors and/or Investment Advisor, and the Policies of Any Sponsor of an Underlying Index Tracked by an ETF, Could Affect the Level of the Index**

Any ETF sponsor or investment advisor may from time to time be called upon to make certain decisions or judgments with respect to the implementation of the strategy of the ETF's investment advisor concerning additions, deletions or substitutions of securities or assets held by the ETF, the manner in which changes affecting the underlying index, if any, are reflected in the ETF, the means of executing trading on behalf of an ETF, and the best means of tracking an underlying index, if any. The ETF sponsor's or investment advisor's decisions or judgments could affect the market price of the shares of the ETF and may adversely affect the level of the index.

In addition, the sponsor of an underlying index tracked by an ETF is responsible for the design and maintenance of such underlying index. The policies of the sponsor of such underlying index concerning the calculation of the underlying index, including decisions regarding the addition, deletion or substitution of the assets included in the underlying index, could affect the level of the underlying index and, consequently, could affect the market price of shares of the ETF and could adversely affect the level of the index, the amount payable on your notes and the market value of your notes.

------

**There is No Assurance That an Active Trading Market Will Continue for the ETFs or That There Will Be Liquidity in Any Such Trading Market; Further, Each ETF is Subject to Management Risks, Securities Lending Risks and Custody Risks**

Although all of the shares of the ETFs are listed for trading on Cboe BZX Exchange, Inc. (Cboe BZX), NYSE Arca, Inc. (NYSE Arca) or the Nasdaq Stock Market (Nasdaq) and a number of similar products have been traded on the Cboe BZX, NYSE Arca, Nasdaq or other securities exchanges for varying periods of time, there is no assurance that an active trading market will continue for the ETFs or that there will be liquidity in any such trading market.

In addition, each ETF is subject to management risk, which is the risk that an ETF's investment advisor's investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results. In addition, each investment advisor is permitted to engage in securities lending with respect to a portion of the applicable ETF's total assets, which could subject such ETF to the risk that the borrower of such loaned securities fails to return the securities in a timely manner or at all.

Further, each ETF is subject to custody risk, which refers to the risks in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. The less developed a country's securities market is, the greater the likelihood of custody problems.

Further, each ETF is subject to listing standards adopted by Cboe BZX, NYSE Arca or Nasdaq, as applicable. There can be no assurance that an ETF will continue to meet the applicable listing requirements, or that an ETF will not be delisted.

#### The ETFs May Be Subject to Pricing Dislocations and Other Market Forces, Which May Adversely Affect the Level of the Index
Even if the net asset value of an ETF's assets is increasing, the market price of its shares may not. Shares of an ETF may trade in the secondary market at times when the ETF does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the ETF accepts purchase and redemption orders. Further, from time to time, an authorized participant, a third party investor, an ETF advisor, an affiliate of an ETF advisor or a fund may invest in an ETF and hold its investment for a specific period of time in order to facilitate commencement of an ETF's operations or for the ETF to achieve size or scale, which could negatively impact such ETF. In addition, shares of each ETF trade at prices at, above or below the most recent net asset value of the ETF's assets. The trading prices of an ETF's shares fluctuate continuously throughout trading hours based on market supply and demand rather than the net asset value. The trading prices of the ETF's shares may deviate significantly from the ETF's net asset value during periods of market volatility, and disruptions due to creations and redemptions of the ETF's shares by authorized participants (or disruptions due to the lack of authorized participants able to create or redeem the ETF's shares) or the existence of extreme market volatility may result in trading prices for shares of the ETF that differ significantly from its net asset value. If any of these dislocations were to occur, the level of the index, the amount payable on your notes and the market value of your notes may be adversely affected.

#### The Values of the ETFs May Not Completely Track the Level of the Indices Underlying Such ETFs
Although the trading characteristics and valuations of the shares of an ETF will usually mirror to some extent the characteristics and valuations of the underlying index, the value of the shares of an ETF may not completely track the level of the underlying index. One of the common reasons this occurs is that an index is a theoretical financial calculation of the performance of certain assets, but an ETF holds an actual investment portfolio. The value of a share of the ETF may reflect transaction costs and fees incurred or imposed by the investment advisor of the ETF as well as the costs to the ETF to buy and sell its assets. These costs and fees are not included in the calculation of the underlying index. Additionally, because an ETF may not actually hold all of the assets that comprise the underlying index, and may invest in securities that are not part of the underlying index, the ETF may not closely track the performance of the underlying index. Some additional reasons for these tracking differences are described under "The Underlying Assets" below. As a result of these tracking differences, the index may not perform as well as an investment linked directly to the underlying indices of the ETFs.

#### The ETFs May Be Subject to Global or Regional Financial Risks, Which May Adversely Affect the Level of the Index
Many of the ETFs invest wholly or substantially in regionally-focused debt or equity securities. If a financial crisis occurs in a region, or if there is another global financial crisis such as the one experienced beginning in 2007/2008, any number (if not all) of the ETFs may be severely affected, which may adversely affect the level of the index.

#### Risks related to ETFs concentrated in the Information Technology sector

#### Certain ETFs Are Concentrated in the Information Technology Sector and Do Not Provide Diversified Exposure
Certain ETFs hold assets that are concentrated in the Information Technology sector, which means the ETFs are more likely to be more adversely affected by any negative performance of the Information Technology sector than ETFs that have more diversified holdings across a number of sectors. Market or economic factors impacting technology companies and companies that rely heavily on technological advances could have a major effect on the value of the ETFs' investments. The value of stocks of technology companies and companies that rely heavily on technology are particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability. Additionally, companies in the Information Technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel.

#### Risks related to the iShares<sup>®</sup> MSCI USA Momentum Factor ETF

#### Momentum Securities Risk
The iShares<sup>®</sup> MSCI USA Momentum Factor ETF tracks an underlying index that is designed to measure the performance of an equity momentum strategy by emphasizing stocks with high price momentum. Stocks that have previously exhibited high momentum characteristics may not experience positive momentum in the future or may experience more volatility than the market as a whole. The underlying index sponsor may be unsuccessful in creating an underlying index that emphasizes momentum securities. In addition, there may be periods when the momentum style of investing is out of favor and the investment performance of the iShares<sup>®</sup> MSCI USA Momentum Factor ETF may suffer.

#### In November 2020, the iShares<sup>®</sup> MSCI USA Momentum Factor ETF Changed the Index it Tracks
The iShares<sup>®</sup> MSCI USA Momentum Factor ETF will generally invest in the securities included in the index it tracks, but may invest in cash, cash equivalents and other securities not included in the index. Prior to November 23, 2020, the iShares<sup>®</sup> MSCI USA Momentum Factor ETF tracked the MSCI USA Momentum Index, but, beginning on November 23, 2020, the iShares<sup>®</sup> MSCI USA Momentum Factor ETF began tracking the MSCI USA Momentum SR Variant Index. Any historical information about the performance of the iShares<sup>®</sup> MSCI USA Momentum Factor ETF for any period before November 23, 2020 was during a period in which the iShares<sup>®</sup> MSCI USA Momentum Factor ETF tracked a different index, and therefore should not be considered information relevant to how the iShares<sup>®</sup> MSCI USA Momentum Factor ETF will perform as it tracks the MSCI USA Momentum SR Variant Index.

The performance of the MSCI USA Momentum SR Variant Index may deviate from the performance of the MSCI USA Momentum Index as a result of its different rebalancing mechanics. Such divergence in performance may occur during any period that includes a rebalancing (whether scheduled or ad-hoc), and may be particularly acute during periods characterized by more frequent ad-hoc rebalancing or market volatility. In addition, BFA expects that the ETF may experience higher tracking error than is typical for similar exchange-traded funds.

#### The Index Which the iShares<sup>®</sup> MSCI USA Momentum Factor ETF Tracks Is a New Index With a Limited Historical Track Record
The MSCI USA Momentum SR Variant Index was launched on May 19, 2020. The index sponsor of the MSCI USA Momentum SR Variant Index has published hypothetical historical information regarding the historical performance of the MSCI USA Momentum SR Variant Index prior to May 19, 2020. Because the MSCI USA Momentum SR Variant Index was not published during those periods, these levels should not be relied upon when making your investment decision.

#### Risks related to the iShares<sup>®</sup> MSCI USA Quality Factor ETF

#### Quality Stocks Risk
The iShares<sup>®</sup> MSCI USA Quality Factor ETF tracks an underlying index that is designed to measure historical and expected high returns on equity, stable earnings growth and low debt-to-asset ratio. However, there is no guarantee that the past performance of these stocks will continue. The underlying index sponsor may be unsuccessful in creating an underlying index that reflects the quality of individual stocks. Companies that issue these stocks may not be able to sustain consistently high returns on equity, earnings and growth year after year and may need to borrow money or issue debt despite their prior history. Earnings, growth and other measures of a stock's quality can be adversely affected by market, regulatory, political, environmental and other factors. The price of a stock also may be affected by factors other than those factors considered by the underlying index sponsor. The degree to which these factors affect a stock's performance can be difficult to predict.

#### Risks related to the iShares<sup>®</sup> MSCI USA Size Factor ETF

#### In December 2018, the MSCI USA Size Factor ETF Changed the Index it Tracks
The MSCI USA Size Factor ETF will generally invest in the securities included in the index it tracks, but may invest in cash, cash equivalents and other securities not included in the index. Prior to December 3, 2018, the MSCI USA Size Factor ETF tracked the MSCI USA Risk Weighted Index, but, beginning on December 3, 2018, the MSCI USA Size Factor ETF began tracking the MSCI USA Low Size Index. Any historical performance of the MSCI USA Size Factor ETF for any period before December 3, 2018 was during a period in which the MSCI USA Size Factor ETF tracked a different index, and therefore should not be considered information relevant to how MSCI USA Size Factor ETF will perform as it tracks the MSCI USA Low Size Index.

#### Low Size Risk
The iShares<sup>®</sup> MSCI USA Size Factor ETF tracks an underlying index that is designed to select equity securities based on certain investment style factors, including low size. Low size companies are those that are on the smaller end of the market capitalization range of securities in the MSCI USA Index. Low size is not a capitalization range similar to large, mid- and small capitalization companies, but rather a factor score determined by a security's relative position within the market capitalization range of the MSCI USA Index.

Low size companies may be more volatile than those of larger companies, and therefore, the iShares<sup>®</sup> MSCI USA Size Factor ETF's share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by larger capitalization companies. Stock prices of low size companies are more vulnerable to adverse business and economic developments. Securities of low size companies may be thinly traded, making it difficult for the iShares<sup>®</sup> MSCI USA Size Factor ETF to buy and sell them. In addition, low size companies may be less financially stable than larger, more established companies and may depend on a small number of essential personnel, making these companies more vulnerable to experiencing adverse effects due to the loss of personnel. Low size companies also may have less diverse product lines than those of larger capitalization companies and are more susceptible to adverse developments concerning their products.

#### Risks related to the iShares<sup>®</sup> MSCI USA Min Vol Factor ETF

#### Volatility Risk

#### Risks related to the iShares<sup>®</sup> MSCI USA Value Factor ETF

#### Value Risk
The iShares<sup>®</sup> MSCI USA Value Factor ETF tracks an underlying index that is designed to measure the performance of securities in the MSCI USA Index that, in the aggregate, have value characteristics and relatively lower valuations relative to the large- and mid-cap U.S. equity market. Value securities are those issued by companies that may be perceived as undervalued. Value securities may fail to appreciate for long periods of time and may never realize their full potential value. The underlying index sponsor may be unsuccessful in creating an underlying index that emphasizes undervalued securities. Value securities have generally performed better than non-value securities during periods of economic recovery (although there is no assurance that they will continue to do so). Value securities may go in and out of favor over time.

#### Risks related to ETFs holding U.S. government debt securities

#### Your Investment is Subject to Concentration Risks
Certain of the ETFs invest in U.S. Treasury bonds that are all obligations of the United States, including the iShares<sup>®</sup> 1-3 Year Treasury Bond ETF, the iShares<sup>®</sup> 7-10 Year Treasury Bond ETF and the iShares<sup>®</sup> 20+ Year Treasury Bond ETF. In addition, the iShares<sup>®</sup> 20+ Year Treasury Bond ETF invests in securities with a similar remaining time to maturity. As a

------

result, these ETFs are concentrated in the performance of bonds issued by a single issuer and having the same general tenor and terms. Although your investment in the notes will not result in the ownership or other direct interest in the U.S. Treasury bonds held by any ETF, the return on your investment in the notes will be subject to certain risks similar to those associated with direct investment in a U.S. Treasury bonds. This increases the risk that any downgrade of the credit ratings of the U.S. government from its current ratings, any increase in risk that the U.S. Treasury may default on its obligations by the market (whether for credit or legislative process reasons) or any other market events that create a decrease in demand for U.S. Treasury bonds would significantly adversely affect such ETFs and may adversely affect the level of the index. In addition, to the extent that any such decrease in demand is more concentrated in particular U.S. Treasury bond maturities, the ETFs that are concentrated in those maturities could be severely affected, which may adversely affect the level of the index.

#### ETFs Holding U.S. Government Bonds May Change in Unexpected Ways
The indexes to which ETFs holding U.S. Treasury bonds tend to be linked tend to have very limited public disclosure about the underlying indexes. The index sponsors of these indexes retain discretion to make changes to the indexes at any time. The lack of detailed information about the indexes and how their constituents may change in the future creates the risk that the indexes could change in the future to perform much differently from the way they would perform if such changes were not made. If the indexes are changed in unexpected ways, the ETFs holding such bonds would similarly change to better reflect the indexes. The performance of the ETFs holding such bonds could be adversely affected in that case, which could adversely affect your investment in the notes.

#### Risks related to ETFs holding debt securities

#### Your Investment is Subject to Income Risk and Interest Rate Risk
The income of ETFs that invest in debt securities, or "bonds," may decline when interest rates fall. This decline can occur because the ETF must invest in lower-yielding bonds as bonds in its portfolio fall outside the time to maturity limits required by the ETF's investment objective or are called, bonds in the underlying index are substituted or the ETF otherwise needs to purchase additional bonds. In addition, an increase in interest rates may cause the value of the fixed rate bonds held by an ETF to decrease, may lead to heightened volatility in the fixed income markets and may adversely affect the liquidity of certain fixed income bonds. Securities with longer durations tend to be more sensitive to interest rate changes, usually making them more volatile than securities with shorter durations. If any of these events occur, the shares of the ETFs invested in bonds and the level of the index could be adversely affected.

#### Some Common Concepts
Each description of an ETF provides information about the particular structure (type of entity) of that ETF. Each of the ETFs files information with the SEC. Information provided to or filed with the SEC can be inspected and copied at the public reference facilities maintained by the SEC or through the SEC's website at sec.gov. The descriptions below will provide the "CIK number" for each of the ETFs, which is an identifying number that will assist you in finding information about the ETFs filed with the SEC.

Each of the ETFs also has certain concepts in common with most or all of the other ETFs. We have described some of these common concepts below.

*<u>Investment Objective</u>*

The investment objective of most ETFs is to achieve investment results that correspond generally to the price and yield performance, before fees and expenses, of a particular index. That type of ETF, sometimes called a "tracking ETF," uses a passive or indexing approach to try to achieve the ETF's investment objective. The investment advisor to the ETF does not try to beat the index; the ETF tracks and does not seek temporary defensive positions when markets decline or appear overvalued. This means, among other things, that a tracking ETF typically will not sell a particular holding just because it is performing poorly. Instead, the ETF seeks to track the index regardless of whether the index level is increasing or decreasing. The descriptions below will indicate the investment objective of each ETF and will indicate which index a particular ETF tracks if it is a tracking ETF. The description also will state how much of the ETF's assets generally will be invested in the securities in the index and what else the ETF may invest in. The descriptions also will state the strategy the investment advisor uses to track the index.

The ETFs that track an equity index seek to track the performance of the "total return" version of such index. A total return index represents the total return earned in a portfolio that tracks the price return index and reinvests dividend income in the overall index, not in the specific stock paying the dividend. The difference between the price return calculation and the total return calculation of an index is that, with respect to the price return calculation, changes in the index level reflect changes in stock prices, whereas with respect to the total return calculation of the index, changes in the index level reflect both movements in stock prices and the reinvestment of dividend income. In addition, some of the ETFs track an index that is calculated on a net daily total return basis, which tracks the price return index and reinvests dividend income in the overall index, except that the dividend income is reinvested net of certain withholding taxes. Notwithstanding an ETF's investment objective to track the performance of the total return version of an index, the return on your notes will not reflect any dividends paid on the ETF shares, on the securities purchased by the ETF or on the securities that comprise the index such ETF tracks. See "Additional Risk Factors Specific to Your Notes — You Have No Shareholder Rights or Rights to Receive Any Shares or Units of Any ETF, or Any Assets Held by Any ETF or the Cash Constituent" in the applicable pricing supplement.

*<u>Tracking Error</u>*

In the case of a tracking ETF, as described above, the difference between the performance of the ETF over a period of time and the performance of the index over such period of time is called the "tracking error" over that period of time. This is typically measured as the difference between the ETF's returns and the index returns over the same period of time. This is also sometimes referred to as the "correlation" between the index and the tracking ETF. An index and ETF are perfectly correlated if the correlation is 1.00 (*i.e.,* the tracking error is 0.00%). Tracking errors can result for a variety of

------

reasons, but one of the common reasons is that an index is a theoretical financial calculation of the performance of certain assets, but an ETF holds an actual investment portfolio. The descriptions below will discuss some of the additional reasons for tracking errors in the ETFs. The ETFs provide information about the performance of the index and the performance of the ETF for the same period. In some cases, the ETFs assume reinvestment of share distributions when calculating the performance of the market price of the shares.

*<u>Creation Units</u>*

Prior to trading in the secondary market, shares of an ETF are issued at net asset value to certain institutional investors (typically market makers or other broker-dealers) only in large block-size units, known as creation units. As a practical matter, only institutions, market makers or large investors purchase or redeem creation units. Except when aggregated in creation units (or upon the liquidation of the ETF), shares of an ETF are not redeemable securities. The descriptions below will describe the size of the creation units for each ETF. For most investors, the important thing to know is that redemptions of creation units may cause temporary dislocations in tracking errors for tracking ETFs.

*<u>Investment Advisor</u>*

Each of the ETFs has an investment advisor. Depending on the structure of the ETF, there may be other key roles with respect to that ETF. Those roles and the entities that perform them will be described below.

*<u>Net Asset Value and Share Prices</u>*

Each of the ETFs calculates a net asset value, or NAV, at the end of each trading day. This value represents the value of the ETF's assets less any applicable fees and expenses. The actual trading price of an ETF's shares or units in the secondary market generally differs (and may deviate significantly during periods of market volatility) from the ETF's daily net asset value. This is because the trading price is affected by market forces such as supply and demand, economic conditions and other factors. For purposes of your notes and the index, the trading prices of the shares or units of the ETFs included in the calculation of the index will be based on the trading prices alone and not the NAV or any indicative values.

#### iShares<sup>®</sup> MSCI USA Momentum Factor ETF
The shares of the iShares<sup>®</sup> MSCI USA Momentum Factor ETF (the "ETF") are issued by iShares<sup>®</sup> Trust, a registered investment company.

• The ETF is a tracking ETF that seeks investment results which correspond generally to the price and yield performance, before fees and expenses, of the MSCI USA Momentum SR Variant Index (the "index"). Prior to November 23, 2020, the ETF tracked the MSCI USA Momentum Index.

• The ETF's investment advisor is BlackRock Fund Advisors ("BFA").

• The ETF's shares trade on the Cboe BZX under the ticker symbol "MTUM".

• The iShares<sup>®</sup> Trust's SEC CIK Number is 0001100663.

• The ETF's inception date was April 16, 2013.

• The ETF's shares are issued or redeemed only in creation units of 50,000 shares or multiples thereof.

Effective August 17, 2020, the name of the ETF changed from the iShares<sup>®</sup> Edge MSCI USA Momentum Factor ETF to the iShares<sup>®</sup> MSCI USA Momentum Factor ETF.

We obtained the following fee information from the iShares*<sup>®</sup>* website without independent verification. The investment advisor is paid a management fee from the ETF based on a percentage of the ETF's average daily net assets, at the annual rate of 0.15%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual ETF operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time. As of December 31, 2022, the aggregate expense ratio of the ETF was 0.15% per annum.

For additional information regarding iShares<sup>®</sup> Trust or BFA, please consult the reports (including the Annual Report to Shareholders on Form N-CSR for the fiscal year ended July 31, 2022) and other information iShares<sup>®</sup> Trust files with the SEC. In addition, information regarding the ETF (including the top ten holdings and weights and sector weights) may be obtained from other sources including, but not limited to, press releases, newspaper articles, other publicly available documents, and the iShares<sup>®</sup> website at us.ishares.com/product_info/fund/overview/MTUM.htm. We are not incorporating by reference the website, the sources listed above or any material they include in this index supplement.

#### Investment Objective
The ETF seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the index. The ETF's investment objective and the index may be changed without the approval of BFA's shareholders.

#### Representative Sampling
BFA uses a representative sampling indexing strategy to manage the ETF. This strategy involves investing in a representative sample of securities that collectively has an investment profile similar to that of the index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the index.

The ETF generally will invest at least 80% of its assets in the component securities of the index and in investments that have economic characteristics that are substantially identical to the component securities of the index (i.e., depositary receipts representing securities of the index) and may invest up to 20% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the index, but which BFA believes will help the ETF track the index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the index. Also, the ETF may lend securities representing up to one-third of the value of the ETF's total assets (including the value of the collateral received).

#### Tracking Error
The performance of the ETF and the index may vary due to a variety of factors, including differences between the securities and other instruments held in the ETF's portfolio and those included in the index, pricing differences, transaction costs incurred by the ETF, the ETF's holding of uninvested cash, differences in timing of the accrual or the valuation of

------

dividends or interest received by the ETF or distributions paid to the ETF's shareholders, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the index or the costs to the ETF of complying with various new or existing regulatory requirements, among other reasons. Tracking error also may result because the ETF incurs fees and expenses, while the index does not. The ETF's use of a representative sampling indexing strategy can be expected to produce a larger tracking error than would result if the ETF used a replication indexing strategy in which an ETF invests in substantially all of the securities in its index in approximately the same proportions as in the index.

#### Industry Concentration Policy
The ETF will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the index is concentrated.

#### MSCI USA Momentum SR Variant Index
The MSCI USA Momentum SR Variant Index aims to reflect the performance of the MSCI USA Momentum Index (for purposes of the descriptions of the MSCI USA Momentum SR Variant Index, the "reference index"), except that the MSCI USA Momentum SR Variant Index is rebalanced by staggering changes in the number of security shares due to rebalancing in equal proportion over three business days ending on the effective date of the reference index rebalancing, whereas the reference index implements the entire rebalancing on the effective date. Please read "Additional Risk Factors Specific to the ETFs—Risks related to the iShares<sup>®</sup> MSCI USA Momentum Factor ETF – The iShares<sup>®</sup> MSCI USA Momentum Factor ETF Recently Changed the Index it Tracks" on S-11. For more information about the reference index, see "The MSCI USA Momentum Index" below.

The MSCI USA Momentum SR Variant Index is calculated, published and disseminated daily by MSCI through numerous data vendors, on the MSCI website and in real time on Bloomberg Financial Markets and Reuters Limited. The MSCI USA Momentum SR Variant Index was launched on May 19, 2020. Additional information about the MSCI USA Momentum SR Variant Index is available on the following website: msci.com/index-methodology. We are not incorporating by reference the website, the sources listed above or any material they include in this index supplement.

#### Rebalancing of the MSCI USA Momentum SR Variant Index
The MSCI USA Momentum SR Variant Index is rebalanced by staggering the changes in the number of shares of securities due to rebalancing in equal proportions over three days: T-2, T-1 and T (where "T" is the effective date of the rebalancing of the reference index, T-1 is the preceding business day, and T-2 is the second preceding business day). In case any of the three consecutive business days ending in business day T is preceded by a scheduled exchange holiday (any day on which any exchange on which any security in the MSCI USA Momentum SR Variant Index is listed has a trading holiday (either full or partial)), the start date of the staggering will be advanced to ensure that the implementation continues to be staggered over three business days (which may be non-consecutive), none of which are preceded by a scheduled exchange holiday. The pro forma MSCI USA Momentum SR Variant Index in general is announced nine business days before T (T-9), where T is the effective date of the rebalancing of the reference index.

Other than with respect to the staggered implementation of rebalancings, the MSCI USA Momentum SR Variant Index generally follows the rebalancing schedule of the reference index. The reference index's scheduled rebalancings occur semi-annually, usually as of the close of the last business day of May and November, coinciding with the May and November semi-annual index review of the reference index (which reference index rebalancing day would serve as the reference date for the staggered rebalancing of the MSCI USA Momentum SR Variant Index, as described below). In addition, the MSCI USA Momentum SR Variant Index generally will be subject to ad-hoc rebalancing if a trigger condition for an ad-hoc rebalancing of the reference index is satisfied, but such ad-hoc rebalancing will also be implemented on a staggered basis (i.e., over three business days). For more information about the rebalancing schedule and trigger conditions for ad-hoc rebalancings of the reference index, see "The MSCI USA Momentum Index—Maintenance of the MSCI USA Momentum Index" below.

For each day of staggering, the number of shares for each security included in the MSCI USA Momentum SR Variant Index equals the *sum* of (i) the number of shares of such security in the reference index effective on the particular date of staggering *plus* (ii) the product of (a) the difference between the targeted number of shares of such security that will be in the reference index on the effective date of the reference index's rebalancing date (T), adjusted for changes to the overall number of shares due to corporate events (spinoffs, mergers, etc.), *minus* the actual number of shares of such security in the reference index on the particular date of staggering *multiplied* by (b) the quotient of N divided 3, where N is the nth day of staggering (e.g., t-2 is the first day of staggering). The number of shares of a security in the reference index effective on a particular date of staggering is calculated as the product of the end of day number of shares of the security as of the close of trading on the prior business day as adjusted for certain corporate events as described in "The MSCI USA Momentum Index—Maintenance of the MSCI USA Momentum Index—Corporate Events" below.

------

#### Maintenance of the MSCI USA Momentum SR Variant Index
Except as otherwise specified below, the MSCI USA Momentum SR Variant Index is generally maintained on the same basis as the reference index.

*<u>Corporate Events</u>*

Corporate event treatment for the MSCI USA Momentum SR Variant Index depends on whether the effective date of the event falls within the staggering period (T-2, T-1, T), or outside the staggering period.

The general treatment of corporate events effective outside the staggering period in the MSCI USA Momentum SR Variant Index aims to minimize turnover outside of index reviews. The methodology aims to appropriately represent an investor's participation in an event based on relevant deal terms and pre-event weighting of the index constituents that are involved. Further, changes in index market capitalization that occur as a result of corporate event implementation will be offset by a corresponding change in the variable weighting factor of the constituent. Additionally, if the frequency of index reviews in the MSCI USA Index is greater than the frequency of index reviews in the MSCI USA Momentum SR Variant Index, the changes made to the MSCI USA Index during intermediate index reviews will be neutralized in the MSCI USA Momentum SR Variant Index.

For more information about the treatment of common corporate events, see "The MSCI USA Momentum Index— Maintenance of the MSCI USA Momentum Index—Corporate Events" below. No new securities will be added (except where noted below in "The MSCI USA Momentum Index— Maintenance of the MSCI USA Momentum Index—Corporate Events") to the MSCI USA Momentum SR Variant Index outside of the staggering period. MSCI USA Index deletions will be reflected simultaneously in the MSCI USA Momentum SR Variant Index.

Events effective in MSCI USA Momentum SR Variant Index during the staggering period incorporate the event implementation in the reference index. The impact of an event on the MSCI USA Momentum SR Variant Index depends on the type of event and calculation date of the index.

#### MSCI USA Momentum Index
The MSCI USA Momentum Index is designed to measure the performance of an equity momentum strategy by emphasizing stocks with high price momentum, while maintaining reasonably high trading liquidity and investment capacity and moderate index turnover, each as determined by MSCI Inc. ("MSCI"). The MSCI USA Momentum Index's constituent stocks exhibit relatively higher momentum characteristics than its traditional market capitalization weighted parent index, the MSCI USA Index. The MSCI USA Index includes U.S. large- and mid-capitalization stocks, as defined by MSCI. For more information about the MSCI USA Index, see "The MSCI USA Index" below.

The MSCI USA Momentum Index is calculated, published and disseminated daily by MSCI through numerous data vendors, on the MSCI website and in real time on Bloomberg Financial Markets and Reuters Limited. The MSCI USA Momentum Index was launched on February 15, 2013. Additional information about the MSCI USA Momentum Index is available on the following website: msci.com/index-methodology. We are not incorporating by reference the website, the sources listed above or any material they include in this index supplement.

#### Construction of the MSCI USA Momentum Index
The MSCI USA Momentum Index selects a predetermined number of constituent securities with the highest risk-adjusted price momentum from the MSCI USA Index. With respect to a security, MSCI defines risk-adjusted price momentum as (i) the excess return over 6- and 12-month time periods over the risk-free rate divided by (ii) the annualized standard deviation of weekly returns over the past three years. The 6- and 12-month risk-adjusted price momentum calculations are then capped/floored at +/-3 standard deviations and translated into an average momentum score. MSCI uses an algorithm to determine the number of constituent securities to be selected from the MSCI USA Index for inclusion in the MSCI USA Momentum Index with an aim to attain a high exposure to the momentum factor while maintaining sufficient market capitalization and number of securities coverage. The number of components is evaluated semi-annually. The weight of each constituent security in the MSCI USA Momentum Index is determined based on the product of the constituent security's momentum score and its market capitalization weight in the MSCI USA Index, as further adjusted to, among others, mitigate the impact of stock-specific risk. Additionally, each individual constituent security is capped at 5%.

MSCI USA Momentum Index rebalancings occur semi-annually, usually as of the close of the last business day of May and November, coinciding with the May and November semi-annual index review of the MSCI USA Index. The pro forma Momentum Indexes are in general announced nine business days before the effective date.

*<u>Calculate Momentum Values</u>*

In order to calculate the momentum score for each security in the MSCI USA Index, the first step is to calculate the 6-month price momentum and the 12-month price momentum on the rebalancing date for that security as follows:

------

• "6-month price momentum" equals (i) the quotient of (a) the price of the security one month prior to the rebalancing date divided by (b) the price of the security seven months prior to the rebalancing date, minus (ii) 1, minus (iii) the 3-month treasury bill rate on the rebalancing date

• "12-month price momentum" equals (i) the quotient of (a) the price of the security one month prior to the rebalancing date divided by (b) the price of the security 13 months prior to the rebalancing date, minus (ii) 1, minus (iii) the 3-month treasury bill rate on the rebalancing date

If the 12-month price momentum is not available, only the 6-month price momentum is used to calculate the momentum score. However, if the 6-month price momentum is not available on the rebalancing date, the momentum score will not be calculated and the security is not eligible for inclusion in the MSCI USA Momentum Index.

*<u>Calculate Risk-Adjusted Momentum Value</u>*

Second, for each security, the 6-month price momentum is used to calculate the 6-month risk-adjusted price momentum, and the 12-month price momentum is used to calculate the 12-month risk-adjusted price momentum, as follows:

• "6-month risk-adjusted price momentum" equals (i) 6-month risk-adjusted price momentum divided by (ii) the annualized standard deviation of weekly USD price returns over the preceding three years

• "12-month risk-adjusted price momentum" equals (i) 12-month risk-adjusted price momentum divided by (ii) the annualized standard deviation of weekly USD price returns over the preceding three years

*<u>Calculate Z-Scores</u>*

Third, for each security, the 6-month risk-adjusted price momentum and the 12-month risk-adjusted price momentum are standardized into z-scores as follows:

• "6-month momentum z-score" equals the number of standard deviations the 6-month risk-adjusted price momentum is from the average 6-month risk-adjusted price momentum for all of the securities in the MSCI USA Index

• "12-month momentum z-score" equals the number of standard deviations the 12-month risk-adjusted price momentum 12-month risk-adjusted price momentum for all of the securities in the MSCI USA Index

*<u>Calculate Momentum Score</u>*

Fourth, the 6-month momentum z-score and 12-month momentum z-score are combined in equal proportions to arrive at a single combined momentum z-score as follows:

(i) if both the 6-month momentum z-score and the 12-month momentum z-score is available, "combined momentum z-score" equals (i) the product of 0.5 times 6-month risk-adjusted price momentum plus (ii) the product of 0.5 times 12-month risk-adjusted price momentum, 9 or

(ii) if the 12-month momentum z-score is not available, "combined momentum z-score" equals the 6-month risk-adjusted price momentum.

Fifth, the combined momentum z-score is then standardized by calculating the standardized momentum z-score. The standardized momentum z-score equals the number of standard deviations the combined momentum z-score is from the average of the combined momentum z-scores for all of the securities in the MSCI USA Index. The standardinzing momentum z-score is then winsorized at +/- 3, i.e., a standardized momentum z-score above 3 is capped at 3 standard deviations and a combined momentum z-score below -3 is floored at -3 standard deviations.

Sixth, the momentum score is then computed from the momentum z-scores as follows:

(i) If the standardized z-score is greater than or equal to 0, the "momentum score" equals 1 plus the momentum z-score; or

(ii) If the momentum z-score is less than 0, the "momentum score" equals the quotient of (i) 1 divided by (ii) the difference of 1 minus the momentum z-score.

*<u>Security Selection</u>*

The number of securities targeted for inclusion in the MSCI USA Momentum Index at initial construction and upon each rebalancing is determined based on certain rules relating to free-float market capitalization (market price per share multiplied by the number of shares held by non-controlling interests) and numbers of constituent securities as described below.

------

*Initial Construction. The number of securities targeted for inclusion in the MSCI USA Momentum Index at initial construction (or on any semi-annual rebalancing when the initial construction methodology is required to be applied, as described below under the caption "—Rebalancing") is determined by (i) ranking each constituent security in the MSCI USA Index according to its momentum z-score (before applying any cap or floor, and using such securities' weights in the MSCI USA Index if multiple securities have the same score) and (ii) applying the following rules in order of priority:*

• if the MSCI USA Index has 25 or fewer constituent securities on the relevant date, each constituent security in the MSCI USA Index is included as a constituent security in the MSCI USA Momentum Index; or

• if 25 or fewer of the highest ranking MSCI USA Index constituent securities account for at least 30% of the MSCI USA Index's free-float market capitalization, the target number of MSCI USA Momentum Index constituent securities will be 25, subject to the rounding rules; or

• if 25 of the highest ranking MSCI USA Index constituent securities DO NOT account for at least 30% of the MSCI USA Index's free-float market capitalization, but the top 10% of the highest ranking MSCI USA Index constituent securities DO account for at least 30% of the MSCI USA Index's free-float market capitalization, the number of constituent securities constituting the top 10% of the highest ranking MSCI USA Index constituent securities, after rounding, is the number of securities targeted for inclusion in the MSCI USA Momentum Index; or

• if the number of top ranking MSCI USA Index constituent securities accounting for 30% of the MSCI USA Index's free-float market capitalization, after rounding, account for less than 40% of the total number of MSCI USA Index constituent securities, such rounded number is the number of securities targeted for inclusion in the MSCI USA Momentum Index; or

• if the number of top ranking MSCI USA Index constituent securities accounting for 30% of the MSCI USA Index's free-float market capitalization, after rounding, account for 40% or more of the total number of MSCI USA Index constituent securities, eliminate each of the lowest ranking MSCI USA Index constituent securities from such rounded number until the number of those remaining account for 40% or less of the total number of MSCI USA Index constituent securities; and

o if the remaining MSCI USA Index constituent securities account for at least 20% of the MSCI USA Index's free-float market capitalization, the number of such remaining MSCI USA Index constituent securities, after rounding, is the number of securities targeted for inclusion in the MSCI USA Momentum Index; or

o if the remaining MSCI USA Index constituent securities account for less than 20% of the MSCI USA Index's free-float market capitalization, add back the next highest ranking MSCI USA Index constituent securities previously eliminated until the MSCI USA Momentum Index's constituent securities account for at least 20% of the MSCI USA Index's free-float market capitalization and such number of MSCI USA Index constituent securities, after rounding, is the number of securities targeted for inclusion in the MSCI USA Momentum Index.

Where indicated above, the following rounding conventions apply:

• if the number of constituent securities is less than 100, round to the nearest 10 constituent securities;

• if the number of constituent securities is greater than or equal to 100 but less than 300, round to the nearest 25 constituent securities; and

• if the number of constituent securities is greater than or equal to 300, round to the nearest 50 constituent securities.

*Rebalancing. The target number of securities for inclusion in the MSCI USA Momentum Index at each semi-annual rebalancing is determined by applying the following rules in order of priority:*

• if the target number of MSCI USA Momentum Index constituent securities on the immediately *preceding* rebalancing date or initial construction (following rebalancing or construction) exceeds the number of MSCI USA Index constituent securities on the rebalancing date, the initial construction methodology described above should be applied to determine the number of constituent securities to be included in the MSCI USA Momentum Index; or

• if the MSCI USA Index has 25 or fewer constituent securities on the rebalancing date, each constituent security in the MSCI USA Index is included as a constituent security in the MSCI USA Momentum Index; or

• if the number of constituent securities included in the MSCI USA Index on the immediately *preceding* rebalancing or initial construction date (following rebalancing or construction) is less than 25, repeat the initial construction process described above to determine the number of constituent securities to be included in the MSCI USA Momentum Index; or

• if the constituent securities of the MSCI USA Momentum Index determined on the rebalancing or initial construction date (following rebalancing or construction) immediately *preceding* the semi-annual rebalancing date account for less

------

than 10% of the MSCI USA Index's free-float market capitalization on the current rebalancing date, repeat the initial construction process described above to determine the constituent securities to be included in the MSCI USA Momentum Index; or<br>

• otherwise, the target number of MSCI USA Momentum Index constituent securities will not change from the immediately preceding rebalancing or construction date (following rebalancing or construction).

#### Weighting Scheme for the MSCI USA Momentum Index
For a given rebalancing effective date, each security eligible for inclusion in the MSCI USA Momentum Index is weighted according to the product of its market capitalization weight in the MSCI USA Index as of the rebalancing date and its momentum score. Weights are then normalized to 100%, with the weight of an individual constituent security over 5% is capped at 5%.

#### Maintenance of the MSCI USA Momentum Index
The MSCI USA Momentum Index is rebalanced on a semi-annual basis, usually as of the close of the last business day of May and November, coinciding with the May and November semi-annual index review of the MSCI USA Index. In addition to the two semi-annual reviews in May and November, the MSCI USA Momentum Index undergoes ad-hoc rebalancing if the change in annualized volatility of the MSCI USA Index (measured using trailing 3-month daily returns) on any monthly measuring date (the ninth business day prior to month end) compared to the prior month is in the 95th percentile of monthly changes in volatility over the available history of the MSCI USA Index. The trigger condition for ad-hoc rebalancing is checked every month.

*<u>Buffer Rules</u>*

To reduce index turnover and enhance index stability, buffer rules are applied to 50% of the fixed number of securities in the MSCI USA Momentum Index. As a result, 50% of the positions in the rebalancing will be selected from among the highest ranking MSCI USA Index constituent securities without regard to whether they are currently included in the MSCI USA Momentum Index and existing constituent securities of the MSCI USA Momentum Index as of the rebalancing date (prior to effecting the rebalancing) will be given priority for the next 50% of constituent security positions. For example, if the fixed number of securities is 100, the buffers are applied between rank 51 and 150. If the target number of MSCI USA Momentum Index constituent securities is not achieved after this step, the highest ranking remaining MSCI USA Index constituent securities are added until the target number is achieved.

*<u>Corporate Events</u>*

The general treatment of corporate events in the MSCI USA Momentum Index aims to minimize turnover outside of index reviews. The methodology aims to appropriately represent an investor's participation in an event based on relevant deal terms and pre-event weighting of the index constituents that are involved. The following section briefly describes the treatment of common corporate events within the MSCI Momentum Indexes. Further, changes in index market capitalization that occur as a result of corporate event implementation will be offset by a corresponding change in the variable weighting factor of the constituent. Additionally, the changes made to the MSCI USA Index during its quarterly index reviews (described below) will be neutralized in the MSCI USA Momentum Index.

No new securities will be added (except where noted below) to the MSCI USA Momentum Index between index reviews. MSCI USA Index deletions will be reflected simultaneously in the MSCI USA Momentum Index.

------

---

| | |
|:---|:---|
| **Event Type** | **Event Details** |
| New additions to the MSCI USA Index | A new security added to the MSCI USA Index (such as IPO and other early inclusions) will not be added to the index. |
| Spin-Offs | All securities created as a result of the spin-off of an existing MSCI USA Momentum Index constituent will be added to the MSCI USA Momentum Index at the time of event implementation. Reevaluation for continued inclusion in the MSCI USA Momentum Index will occur at the subsequent index review. |
| Merger/acquisition | For mergers and acquisitions, the acquirer's post event weight will account for the proportionate amount of shares involved in deal consideration, while cash proceeds will be invested across the MSCI USA Momentum Index.<br>If an existing MSCI USA Momentum Index constituent is acquired by a security that is not a constituent of the MSCI USA Momentum Index, the existing constituent will be deleted from the MSCI USA Momentum Index and the acquiring non-constituent will not be added to the MSCI USA Momentum Index. |
| Changes in security characteristics | A security will continue to be a constituent of the MSCI USA Momentum Index if there are changes in characteristics (country, sector, size segment, etc.). Reevaluation for continued inclusion in the MSCI USA Momentum Index will occur at the subsequent index review. |

#### MSCI USA Index
MSCI USA Index is a free-float adjusted market capitalization weighted index that is designed to measure the performance of the large- and mid-cap segments of the U.S. equity market. The MSCI USA Index is member of the MSCI Global Equity Indices and represents the U.S. equity portion of the global benchmark MSCI ACWI Index. The MSCI USA Index has a base date of December 31, 1969.

#### Construction of the MSCI USA Index
MSCI undertakes an index construction process, which involves: (i) defining the equity universe; (ii) determining the market investable equity universe for each market; (iii) determining market capitalization size segments for each market; (iv) applying index continuity rules for standard indices; and (v) classifying securities under the Global Industry Classification Standard. The MSCI USA Index is a standard index, meaning that only securities that would qualify for inclusion in a large-cap index or a mid-cap index will be included as described below.

*<u>Defining the Equity Universe</u>*

*Identifying Eligible Equity Securities: The equity universe for the MSCI USA Index initially looks at securities classified as belonging to the United States, which is classified as "developed markets". All listed equity securities, including real estate investment trusts are eligible for inclusion in the equity universe. Limited partnerships, limited liability companies and business trusts, which are listed in the US and are not structured to be taxed as limited partnerships, are likewise eligible for inclusion in the equity universe. Conversely, mutual funds, exchange traded funds, equity derivatives and most investment trusts are not eligible for inclusion in the equity universe. Preferred shares that exhibit characteristics of equity securities are eligible.*

*Country Classification of Eligible Securities: Each company and its securities (i.e., share classes) are classified in one and only one country, which allows for a distinctive sorting of each company by its respective country.*

*<u>Determining the Market Investable Equity Universes</u>*

A market investable equity universe for a market is derived by (i) identifying eligible listings for each security in the equity universe; and (ii) applying investability screens to individual companies and securities in the equity universe that are classified in that market. A market is generally equivalent to a single country. The global investable equity universe is the aggregation of all market investable equity universes.

(i) Identifying Eligible Listings: A security may have a listing in the country where it is classified (a "local listing") and/or in a different country (a "foreign listing"). A security may be represented by either a local listing or a foreign listing (including a depositary receipt) in the global investable equity universe. A security may be represented by a foreign listing only if the security is classified in a country that meets the foreign listing materiality requirement (as described below), and the security's foreign listing is traded on an eligible stock exchange of a developed market country if the security is

------

classified in a developed market country or, if the security is classified in an emerging market country, an eligible stock exchange of a developed market country or an emerging market country.

In order for a country to meet the foreign listing materiality requirement, the following is determined: all securities represented by a foreign listing that would be included in the country's MSCI Country Investable Market Index if foreign listings were eligible from that country. The aggregate free-float adjusted market capitalization for all such securities should represent at least (i) 5% of the free float-adjusted market capitalization of the relevant MSCI Country Investable Market Index and (ii) 0.05% of the free-float adjusted market capitalization of the MSCI ACWI Investable Market Index. If a country does not meet the foreign listing materiality requirement, then securities in that country may not be represented by a foreign listing in the global investable equity universe.

(ii) Applying Investability Screens: The investability screens used to determine the investable equity universe in each market are:

(a) *Equity Universe Minimum Size Requirement*: This investability screen is applied at the company level. In order to be included in a market investable equity universe, a company must have the required minimum full market capitalization. The equity universe minimum size requirement applies to companies in all markets and is derived as follows:

• First, the companies in the developed market equity universe are sorted in descending order of full market capitalization and the cumulative coverage of the free float-adjusted market capitalization of the developed market equity universe is calculated for each company. Each company's free float-adjusted market capitalization is represented by the aggregation of the free float-adjusted market capitalization of the securities of that company in the equity universe.

• Second, when the cumulative free float-adjusted market capitalization coverage of 99% of the sorted equity universe is achieved, by adding each company's free float-adjusted market capitalization in descending order, the full market capitalization of the company that reaches the 99% threshold defines the equity universe minimum size requirement.

• The rank of this company by descending order of full market capitalization within the developed market equity universe is noted, and will be used in determining the equity universe minimum size requirement at the next rebalance.

As of November 2022, the equity universe minimum size requirement was set at US$292,000,000. Companies with a full market capitalization below this level are not included in any market investable equity universe. The equity universe minimum size requirement is reviewed and, if necessary, revised at each semi-annual index review, as described below.

(b) *Equity Universe Minimum Free Float-Adjusted Market Capitalization Requirement*: This investability screen is applied at the individual security level. To be eligible for inclusion in a market investable equity universe, a security must have a free float-adjusted market capitalization equal to or higher than 50% of the equity universe minimum size requirement.

(c) *Minimum Liquidity Requirement:* This investability screen is applied at the individual security level. To be eligible for inclusion in a market investable equity universe, a security must have at least one eligible listing that has adequate liquidity as measured by its 12-month and 3-month annualized traded value ratio ("ATVR") and 3-month frequency of trading. The ATVR attempts to mitigate the impact of extreme daily trading volumes and takes into account the free float-adjusted market capitalization of securities. A minimum liquidity level of 20% of the 3-month ATVR and 90% of 3-month frequency of trading over the last 4 consecutive quarters, as well as 20% of the 12-month ATVR, are required for inclusion of a security in a market investable equity universe of a developed market. A minimum liquidity level of 15% of the 3-month ATVR and 80% of 3-month frequency of trading over the last 4 consecutive quarters, as well as 15% of the 12-month ATVR, are required for inclusion of a security in a market investable equity universe of an emerging market.

Only one listing per security may be included in the market investable equity universe. In instances where a security has two or more eligible listings that meet the above liquidity requirements, then the following priority rules are used to determine which listing will be used for potential inclusion of the security in the market investable equity universe:

(1) Local listing (if the security has two or more local listings, then the listing with the highest 3-month ATVR will be used).

(2) Foreign listing in the same geographical region (MSCI classifies markets into three main geographical regions: EMEA, Asia Pacific and Americas. If the security has two or more foreign listings in the same geographical region, then the listing with the highest 3-month ATVR will be used).

(3) Foreign listing in a different geographical region (if the security has two or more foreign listings in a different geographical region, then the listing with the highest 3-month ATVR will be used).

------

Due to liquidity concerns relating to securities trading at very high stock prices, a security that is currently not a constituent of a MSCI Global Investable Markets Index that is trading at a stock price above US$10,000 will fail the liquidity screening and will not be included in any market investable equity universe.

(d) *Global Minimum Foreign Inclusion Factor Requirement:* This investability screen is applied at the individual security level. To determine the free float of a security, MSCI considers the proportion of shares of such security available for purchase in the public equity markets by international investors. In practice, limitations on the investment opportunities for international investors include: strategic stakes in a company held by private or public shareholders whose investment objective indicates that the shares held are not likely to be available in the market; limits on the proportion of a security's share capital authorized for purchase by non-domestic investors; or other foreign investment restrictions which materially limit the ability of foreign investors to freely invest in a particular equity market, sector or security.

MSCI will then derive a "foreign inclusion factor" for the company that reflects the proportion of shares outstanding that is available for purchase in the public equity markets by international investors. MSCI will then "float-adjust" the weight of each constituent company in an index by the company's foreign inclusion factor.

Once the free float factor has been determined for a security, the security's total market capitalization is then adjusted by such free float factor, resulting in the free float-adjusted market capitalization figure for the security.

(e) *Minimum Length of Trading Requirement:* This investability screen is applied at the individual security level. For an initial public offering to be eligible for inclusion in a market investable equity universe, the new issue must have started trading at least three months before the implementation of a semi-annual index review. This requirement is applicable to small new issues in all markets. Large initial public offerings are not subject to the minimum length of trading requirement and may be included in a market investable equity universe and a standard index, such as the MSCI USA Index, outside of a quarterly or semi-annual index review.

(f) *Minimum Foreign Room Requirement:* This investability screen is applied at the individual security level. For a security that is subject to a foreign ownership limit to be eligible for inclusion in a market investable equity universe, the proportion of shares still available to foreign investors relative to the maximum allowed (referred to as "foreign room") must be at least 15%.

(g) *Financial Reporting Requirement*: For any companies classified as belonging to the United States, the company must file a Form 10-K/10-Q to be eligible for inclusion in the USA investable equity universe.

*<u>Determining Market Capitalization Size Segments for Each Market</u>*

Once a market investable equity universe is defined, it is segmented into the following size-based indices:

• Investable Market Index (Large Cap + Mid Cap + Small Cap)

• Standard Index (Large Cap + Mid Cap)

• Large Cap Index

• Mid Cap Index

• Small Cap Index

Creating the size segment indices in each market involves the following steps: (i) defining the market coverage target range for each size segment; (ii) determining the global minimum size range for each size segment; (iii) determining the market size-segment cutoffs and associated segment number of companies; (iv) assigning companies to the size segments; and (v) applying final size-segment investability requirements. For developed market indices, the market coverage for a standard index is 85%. As of October 2022, the global minimum size range for a developed market standard index is a full market capitalization of USD 3.53 billion to USD 8.12 billion.

*<u>Applying Index Continuity Rules for Standard Indices</u>*

In order to achieve index continuity, as well as provide some basic level of diversification within a market index, notwithstanding the effect of other index construction rules, a minimum number of five constituents will be maintained for a developed market standard index and a minimum number of three constituents will be maintained for an emerging market standard index, and involves the following steps:

If after the application of the index construction methodology, a developed market standard index contains fewer than five securities or an emerging market standard index contains fewer than three securities, then the largest securities by free float-adjusted market capitalization are added to the index in order to reach the minimum number of required constituents.

At subsequent index reviews, if the minimum number of securities described above is not met, then after the market investable equity universe is identified, the securities are ranked by free float-adjusted market capitalization, however, in

------

order to increase stability the free float-adjusted market capitalization of the existing index constituents (prior to review) is multiplied by 1.50, and securities are added until the desired minimum number of securities is reached.

*<u>Classifying Securities under the Global Industry Classification Standard</u>*

All securities in the global investable equity universe are assigned to the industry that best describes their business activities. The Global Industry Classification Standard classification of each security is used by MSCI to construct additional indices.

#### Calculation Methodology for the MSCI USA Index
The performance of the MSCI USA Index is a free-float weighted average of the U.S. dollar values of its component securities, subject to the daily total return methodology (as described below).

Prices used to calculate the component securities are the official exchange closing prices or prices accepted as such in the relevant market. In the case of a market closure, or if a security does not trade on a specific day or during a specific period, MSCI carries the latest available closing price. In the event of a market outage resulting in any component security price to be unavailable, MSCI will generally use the last reported price for such component security for the purpose of performance calculation. If MSCI determines that another price is more appropriate based on the circumstances, an announcement would be sent to clients with the related information. Closing prices are converted into U.S. dollars, as applicable, using the closing spot exchange rates calculated by WM/Reuters at 4:00 P.M. London Time.

*Daily Total Return Methodology* 

The MSCI USA Index is a daily total return index. A daily total return index measures the market performance, including price performance and income from regular cash distributions. This income is reinvested in the MSCI USA Index and thus makes up part of the total index performance. MSCI's daily total return methodology reinvests cash dividends in the MSCI USA Index the day the security is quoted ex-dividend, or on the ex-date (converted to U.S. dollars, as applicable). Certain dividends, including special/extraordinary dividends and commemorative dividends, are reinvested in the MSCI USA Index if, a day prior to the ex-date, the dividend impact on price is less than 5%. If the impact is 5% or more, the dividend will be reinvested in the MSCI USA Index through a price adjustment on the ex-date. A specific price adjustment is always applied for stock dividends that are issued at no cost to the shareholders, an extraordinary capital repayment or a dividend paid in the shares of another company. Cash payments related to corporate events, such as mergers and acquisitions, are considered on a case-by-case basis.

Notwithstanding the ETF's investment objective, the return on your notes will not reflect any dividends paid on the ETF shares, on the securities purchased by the ETF or on the securities that comprise the MSCI USA Index.

#### Maintenance of the MSCI USA Index
In order to maintain the representativeness of the MSCI USA Index, structural changes may be made by adding or deleting component securities. Currently, such changes may generally only be made on four dates throughout the year: after the close of the last business day of each February, May, August and November.

The MSCI USA Index is maintained with the objective of reflecting, on a timely basis, the evolution of the underlying equity markets. In maintaining the MSCI USA Index, emphasis is also placed on its continuity, continuous investability of constituents and replicability of the index and on index stability and minimizing turnover.

MSCI classifies index maintenance in three broad categories. The first consists of ongoing event related changes, such as mergers and acquisitions. The second category consists of quarterly index reviews, aimed at promptly reflecting other significant market events. The third category consists of semi-annual index reviews that systematically re-assess the various dimensions of the equity universe.

Ongoing event-related changes to the MSCI USA Index are the result of mergers, acquisitions, spin-offs, bankruptcies, reorganizations and other similar corporate events. They can also result from capital reorganizations in the form of rights issues, stock bonus issues, public placements and other similar corporate actions that take place on a continuing basis. MSCI will remove from the index as soon as practicable securities of companies that file for bankruptcy or other protection from their creditors, that are suspended and for which a return to normal business activity and trading is unlikely in the near future; or that fail stock exchange listing requirements with a delisting announcement. Securities may also be considered for early deletion in other significant cases, such as decreases in free float and foreign ownership limits, or when a constituent company acquires or merges with a non-constituent company or spins-off another company. In practice, when a constituent company is involved in a corporate event which results in a significant decrease in the company's free float-adjusted market capitalization or the company decreases its foreign inclusion factor to below 0.15, the securities of that constituent company are considered for early deletion from the indices simultaneously with the event unless, in either case, it is a standard index constituent with a minimum free float-adjusted market capitalization meeting

------

at least two-thirds of 1.8 times one-half of the standard index interim size segment cut-off. Share conversions may also give rise to an early deletion. Changes in number of shares and foreign inclusion factors resulting from primary equity offerings representing at least 5% of the security's pre-event number of shares are implemented as of the close of the first trading day of the new shares, if all necessary information is available at that time. Otherwise, the event is implemented as soon as practicable after the relevant information is made available. MSCI implements pending number of shares and/or free float updates simultaneously with the event, unless the change in number of shares is less than 1% on a post-event number of shares basis, in which case it will be implemented at a subsequent index review. Changes in the number of shares smaller than 5% are implemented at a subsequent index review. Secondary offerings/block sales with sizes representing at least 5% of the security's pre-event number of shares are implemented at the time of the event. All changes resulting from corporate events are announced prior to their implementation, provided all necessary information on the event is available.

MSCI's quarterly index review process is designed to ensure that the MSCI USA Index continues to be an accurate reflection of evolving equity markets. This goal is achieved by timely reflecting significant market driven changes that were not captured in each index at the time of their actual occurrence and that should not wait until the semi-annual index review due to their importance. These quarterly index reviews may result in additions and deletions of component securities from the MSCI USA Index and changes in "foreign inclusion factors" and in number of shares. Additions and deletions to component securities may result from: the addition of large companies that did not meet the minimum size criterion for inclusion at the time of their initial public offering or secondary offering; the replacement of companies which are no longer suitable industry representatives; the deletion of securities whose overall free float has fallen to less than 15% and that do not meet specified criteria; the deletion of securities that have become very small or illiquid; and the addition or deletion of securities as a result of other market events. Significant changes in free float estimates and corresponding changes in the foreign inclusion factor for component securities may result from: corporate events that should have been implemented at the time of such event but could not be reflected immediately due to lack of publicly available details at the time of the event; exercise of IPO over-allotment options which result in an increase in free float; increases in foreign ownership limits; decreases in foreign ownership limits which did not require foreign investors to immediately sell shares in the market; re-estimates of free float figures resulting from the reclassification of shareholders from strategic to non-strategic, and vice versa; the end of lock-up periods or expiration of loyalty incentives for non-strategic shareholders; and conversion of a non-index constituent share class or an unlisted line of shares which has an impact on index constituents. However, no changes in foreign inclusion factors are implemented for any of the above events if the change in free float estimate is less than 1%, except in cases of correction. Small changes in the number of shares resulting from, for example, exercise of options or warrants and employee stock option plans, conversion of convertible bonds or other instruments (including periodic conversion of preferred stocks), conversion of a non-index constituent share class or an unlisted line of shares which has an impact on index constituents, periodical conversion of a share class into another share class, exercise of over-allotment options, periodic share buybacks, the cancellation of shares, acquisition for shares of non-listed companies or assets, or other events that could not be implemented on or near the effective dates where no price adjustment factor is necessary, are generally updated at the quarterly index review rather than at the time of the event. The results of the quarterly index reviews are announced at least two weeks in advance of their effective implementation dates as of the close of the last business day of February and August. MSCI has noted that consistency is a factor in maintaining the MSCI USA Index.

MSCI's semi-annual index review is designed to systematically reassess the component securities of the MSCI USA Index. During each semi-annual index review, the universe of component securities is updated and the global minimum size range for the MSCI USA Index is recalculated, which is based on the full market capitalization and the cumulative free float-adjusted market capitalization coverage of each security that is eligible to be included in the MSCI USA Index. The following MSCI USA Index maintenance activities, among others, are undertaken during each semi-annual index review: the list of countries in which securities may be represented by foreign listings is reviewed; the component securities are updated by identifying new equity securities that were not part of the MSCI USA Index at the time of the previous quarterly index review; the minimum size requirement for the MSCI USA Index is updated and new companies are evaluated relative to the new minimum size requirement; existing component securities that do not meet the minimum liquidity requirements of the MSCI USA Index may be removed (or, with respect to any such security that has other listings, a determination is made as to whether any such listing can be used to represent the security in the market investable universe); and changes in "foreign inclusion factors" are implemented (provided the change in free float is greater than 1%, except in cases of correction). During a semi-annual index review, component securities may be added or deleted from the MSCI USA Index for a range of reasons, including the reasons discussed with respect to component securities changes during quarterly index reviews as discussed above. Foreign listings may become eligible to represent securities only from the countries that met the foreign listing materiality requirement during the previous semi-annual index review (this requirement is applied only to countries that do not yet include foreign listed securities). Once a country meets the foreign listing materiality requirement at a given semi-annual index review, foreign listings will remain eligible for such country even if the foreign listing materiality requirements are not met in the future.

------

The results of the semi-annual index reviews are announced at least two weeks in advance of their effective implementation date as of the close of the last business day of May and November.

MSCI USA Index maintenance also includes monitoring and completing adjustments for share changes, stock splits, stock dividends, and stock price adjustments due to company restructurings or spin-offs as well as deleting constituents that enter the ineligible alert boards.

These guidelines and the policies implementing the guidelines are the responsibility of, and, ultimately, subject to adjustment by, MSCI.

#### iShares<sup>®</sup> MSCI USA Value Factor ETF
The shares of the iShares<sup>®</sup> MSCI USA Value Factor ETF (the "ETF") are issued by iShares<sup>®</sup> Trust, a registered investment company.

• The ETF is a tracking ETF that seeks investment results which correspond generally to the price and yield performance, before fees and expenses, of the MSCI USA Enhanced Value Index (the "index").

• The ETF's investment advisor is BlackRock Fund Advisors ("BFA").

• The ETF's shares trade on the Cboe BZX under the ticker symbol "VLUE".

• The iShares<sup>®</sup> Trust's SEC CIK Number is 0001100663.

• The ETF's inception date was April 16, 2013.

• The ETF's shares are issued or redeemed only in creation units of 50,000 shares or multiples thereof.

Effective August 17, 2020, the name of the ETF changed from the iShares<sup>®</sup> Edge MSCI USA Value Factor ETF to the iShares<sup>®</sup> MSCI USA Value Factor ETF.

We obtained the following fee information from the iShares*<sup>®</sup>* website without independent verification. The investment advisor is paid a management fee from the ETF based on a percentage of the ETF's average daily net assets, at the annual rate of 0.15%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual ETF operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time. As of December 31, 2022, the aggregate expense ratio of the ETF was 0.15% per annum.

For additional information regarding iShares<sup>®</sup> Trust or BFA, please consult the reports (including the Annual Report to Shareholders on Form N-CSR for the fiscal year ended July 31, 2022) and other information iShares<sup>®</sup> Trust files with the SEC. In addition, information regarding the ETF (including the top ten holdings and weights and sector weights) may be obtained from other sources including, but not limited to, press releases, newspaper articles, other publicly available documents, and the iShares<sup>®</sup> website at us.ishares.com/product_info/fund/overview/VLUE.htm. We are not incorporating by reference the website, the sources listed above or any material they include in this index supplement.

#### Investment Objective
The ETF seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the index. The ETF's investment objective and the index may be changed without the approval of BFA's shareholders.

#### Representative Sampling
BFA uses a representative sampling indexing strategy to manage the ETF. This strategy involves investing in a representative sample of securities that collectively has an investment profile similar to that of the index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the index.

The ETF generally will invest at least 80% of its assets in the component securities of the index and in investments that have economic characteristics that are substantially identical to the component securities of the index (i.e., depositary receipts representing securities of the index) and may invest up to 20% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the index, but which BFA believes will help the ETF track the index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the index. Also, the ETF may lend securities representing up to one-third of the value of the ETF's total assets (including the value of the collateral received).

#### Tracking Error
The performance of the ETF and the index may vary due to a variety of factors, including differences between the securities and other instruments held in the ETF's portfolio and those included in the index, pricing differences, transaction costs incurred by the ETF, the ETF's holding of uninvested cash, differences in timing of the accrual or the valuation of dividends or interest received by the ETF or distributions paid to the ETF's shareholders, the requirements to maintain

------

pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the index or the costs to the ETF of complying with various new or existing regulatory requirements, among other reasons. Tracking error also may result because the ETF incurs fees and expenses, while the index does not. The ETF's use of a representative sampling indexing strategy can be expected to produce a larger tracking error than would result if the ETF used a replication indexing strategy in which an ETF invests in substantially all of the securities in its index in approximately the same proportions as in the index.

#### Industry Concentration Policy
The ETF will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the index is concentrated.

#### MSCI USA Enhanced Value Index
The MSCI USA Enhanced Value Index is designed to measure the performance of securities in the MSCI USA Index that exhibit higher value characteristics relative to their peers within the corresponding Global Industry Classification Standard (GICS<sup>®</sup>) sector. The MSCI USA Index includes U.S. large- and mid-capitalization stocks, as defined by MSCI Inc. ("MSCI"). MSCI divides the companies included in the MSCI USA Enhanced Value Index into eleven GICS sectors: Communication Services, Consumer Discretionary, Consumer Staples, Energy, Financials, Health Care, Industrials, Information Technology, Materials, Real Estate and Utilities. For additional information about the MSCI USA Index, please see "iShares<sup>®</sup> MSCI USA Momentum Factor ETF — The MSCI USA Index" above.

The MSCI USA Enhanced Value Index is calculated, published and disseminated daily by MSCI through numerous data vendors, on the MSCI website and in real time on Bloomberg Financial Markets and Reuters Limited. The MSCI USA Enhanced Value Index was launched on December 12, 2014. Additional information about the MSCI USA Enhanced Value Index is available on the following website: msci.com/index-methodology. We are not incorporating by reference the website, the sources listed above or any material they include in this index supplement.

#### Construction of the MSCI USA Enhanced Value Index
To construct the MSCI USA Enhanced Value Index, MSCI selects a predetermined number of constituent securities from the MSCI USA Index based on a value weighting using the following fundamental values:

(1) forward price-to-earnings;

(2) price-to-book value; and

(3) enterprise value-to-cash flow from operations,

(except companies in the Financials sector do not consider enterprise value-to-cash flow from operations and companies in the Real Estate sector are evaluated based on enterprise value-to-cash flow from operations alone). MSCI uses an algorithm to determine the number of constituent securities to be selected from the MSCI USA Index for inclusion in the MSCI USA Enhanced Value Index with an aim to maintain sufficient market capitalization and number of securities coverage. The number of components is evaluated semi-annually. MSCI assigns weights by multiplying a constituent security's value score by its market capitalization. Weights in the MSCI USA Enhanced Value Index are next normalized so that sectors in the MSCI USA Enhanced Value Index represent the same relative weight as in the MSCI USA Index, thereby promoting sector neutrality.

*<u>Calculate the Z-Score for Each Variable</u>*

The z-score with respect to each of the variables for each security is calculated using the mean and standard deviation of the inverse of the corresponding variable. The z-score with respect to each individual variable is computed for each constituent security within the MSCI USA Index, and generally measures the extent to which an individual security is an outlier with respect to a particular variable compared to all of the constituent securities included in the MSCI USA Index, measured in terms of standard deviations. The variables used are as follows:

• forward price-to-earnings, price-to-book value and enterprise value-to-cash flow from operations for all securities except for those classified in "Financials" or "Real Estate" sectors;

• forward price-to-earnings and price-to-book value for all securities classified in the "Financials" sector; and

• enterprise value-to-cash flow from operations for all securities classified in the "Real Estate" sector.

The latest available data at the time of rebalancing is used for the individual value descriptors.

------

*<u>Calculate the</u> <u>Sector Relative Value Z-Score</u>*

After calculating individual variable z-scores, a composite value z-score for each security is computed by taking the weighted average of individual variable z-scores for each security. Each individual variable z-score is assigned an equal weight (e.g., a 1/3 weight is assigned when 3 variables are used, a 1/2 weight when 2 variables are used (i.e., for Financial sector) and a weight of 1 when 1 variable is used (i.e., Real Estate sector)). However, no adjustment to the weights will be made to compensate for missing variables (e.g., for a non-Financial/non-Real Estate sector security, the weight of the remaining variable will remain 1/3 if the other 2 variables are not available).

A sector relative score is then derived from the composite value z-score. It is arrived at by standardizing the composite value z-score within each sector. A sector relative score above 3 is capped at 3 standard deviations and a sector relative score below -3 is floored at -3 standard deviations.

*<u>Calculate the Final Value Score</u>*

The final value score is computed from the sector relative z-score as follows:

(i) If the sector relative z-score is *greater than* or *equal to* 0, the "final value score" equals 1 *plus* the sector relative z-score; or

(ii) If the sector relative z-score is *less than* 0, the "final value score" equals the *quotient* of (i) 1 *divided* by (ii) the *difference* of 1 *minus* the sector relative z-score

*<u>Security Selection</u>*

In order to be selected for inclusion in the MSCI USA Enhanced Value Index, a constituent security's final value score must rank among the highest final value scores in the MSCI USA Index. The number of securities targeted for inclusion in the MSCI USA Enhanced Value Index at initial construction and upon each rebalancing is then determined based on certain rules relating to free-float market capitalization (market price per share multiplied by the number of shares held by non-controlling interests) and numbers of constituent securities as described below.

*Initial Construction. The number of securities targeted for inclusion in the MSCI USA Enhanced Value Index at initial construction (or on any semi-annual rebalancing when the initial construction methodology is required to be applied, as described below under the caption "—Rebalancing") is determined by (i) ranking each constituent security in the MSCI USA Index according to its final value score (using such securities' weights in the MSCI USA Index if multiple securities have the same score) and (ii) applying the following rules in order of priority:*

• if the MSCI USA Index has 25 or fewer constituent securities on the relevant date, each constituent security in the MSCI USA Index is included as a constituent security in the MSCI USA Enhanced Value Index; or

• if 25 or fewer of the highest ranking MSCI USA Index constituent securities account for at least 30% of the MSCI USA Index's free-float market capitalization, the target number of Value Index constituent securities will be 25, subject to the rounding rules; or

• if 25 of the highest ranking MSCI USA Index constituent securities do <u>not</u> account for at least 30% of the MSCI USA Index's free-float market capitalization, but the top 10% of the highest ranking MSCI USA Index constituent securities <u>do</u> account for at least 30% of the MSCI USA Index's free-float market capitalization, the number of constituent securities constituting the top 10% of the highest ranking MSCI USA Index constituent securities, after rounding, is the number of securities targeted for inclusion in the MSCI USA Enhanced Value Index; or

• if the number of top ranking MSCI USA Index constituent securities accounting for 30% of the MSCI USA Index's free-float market capitalization, after rounding, account for less than 40% of the total number of MSCI USA Index constituent securities, such rounded number is the number of securities targeted for inclusion in the MSCI USA Enhanced Value Index; or

• if the number of top ranking MSCI USA Index constituent securities accounting for 30% of the MSCI USA Index's free-float market capitalization, after rounding, account for 40% or more of the total number of MSCI USA Index constituent securities, eliminate each of the lowest ranking MSCI USA Index constituent securities from such rounded number until the number of those remaining account for 40% or less of the total number of MSCI USA Index constituent securities; and

------

o if the remaining MSCI USA Index constituent securities account for at least 20% of the MSCI USA Index's free-float market capitalization, the number of such remaining MSCI USA Index constituent securities, after rounding, is the number of securities targeted for inclusion in the MSCI USA Enhanced Value Index; or

o if the remaining MSCI USA Index constituent securities account for less than 20% of the MSCI USA Index's free-float market capitalization, add back the next highest ranking MSCI USA Index constituent securities previously eliminated until the MSCI USA Enhanced Value Index's constituent securities account for at least 20% of the MSCI USA Index's public float and such number of MSCI USA Index constituent securities, after rounding, is the number of securities targeted for inclusion in the MSCI USA Enhanced Value Index.

Where indicated above, the following rounding conventions apply:

• if the number of constituent securities is less than 100, round to the nearest 10 constituent securities;

• if the number of constituent securities is greater than or equal to 100 but less than 300, round to the nearest 25 constituent securities; and

• if the number of constituent securities is greater than or equal to 300, round to the nearest 50 constituent securities.

*Rebalancing. The target number of securities for inclusion in the MSCI USA Enhanced Value Index at each semi-annual rebalancing is determined by applying the following rules in order of priority:*

• if the target number of MSCI USA Enhanced Value Index constituent securities on the immediately *preceding* rebalancing date or initial construction (following rebalancing or construction) exceeds the number of MSCI USA Index constituent securities on the rebalancing date, the initial construction methodology described above should be applied to determine the number of constituent securities to be included in the MSCI USA Enhanced Value Index; or

• if the MSCI USA Index has 25 or fewer constituent securities on the rebalancing date, each constituent security in the MSCI USA Index is included as a constituent security in the MSCI USA Enhanced Value Index; or

• if the number of constituent securities included in the MSCI USA Index on the immediately *preceding* rebalancing or initial construction date (following rebalancing or construction) is less than 25, repeat the initial construction process described above to determine the number of constituent securities to be included in the MSCI USA Enhanced Value Index; or

• if the constituent securities of the MSCI USA Enhanced Value Index determined on the rebalancing or initial construction date (following rebalancing or construction) immediately *preceding* the semi-annual rebalancing date account for less than 10% of the MSCI USA Index's free-float market capitalization on the current rebalancing date, repeat the initial construction process described above to determine the constituent securities to be included in the MSCI USA Enhanced Value Index; or

• otherwise, the target number of MSCI USA Enhanced Value Index constituent securities will not change from the immediately preceding rebalancing or construction date (following rebalancing or construction).

#### Weighting Scheme for the MSCI USA Enhanced Value Index
The securities selected above are assigned weights in proportion to their market capitalization weight in the MSCI USA Index and final value score. These weights are then updated to implement sector neutrality (i.e., the weight of each sector in the MSCI USA Enhanced Value Index is equated with the weight of that sector in the MSCI USA Index). This is done by normalizing the weights of the constituents within each sector to reflect the effective MSCI USA Index sector weight. The final security level inclusion factor is determined as the ratio of the final security level weight and the security level pro forma market capitalization weight in the MSCI USA Index.

#### Maintenance of the MSCI USA Enhanced Value Index
The MSCI USA Enhanced Value Index is rebalanced semi-annually and the changes from the rebalancing are made as of the close of the last business day of each May and November, to coincide with the semi-annual index reviews of the MSCI USA Index, using fundamental values from the end of April and October, respectively. The pro forma MSCI USA Enhanced Value Index is generally announced nine business days before the effective date.

*<u>Buffer Rules</u>*

To reduce index turnover and enhance index stability, buffer rules are applied to 50% of the fixed number of securities in the MSCI USA Enhanced Value Index. As a result, 50% of the positions in the rebalancing will be selected from among the highest ranking MSCI USA Index constituent securities without regard to whether they are currently included in the MSCI USA Enhanced Value Index and existing constituent securities of the MSCI USA Enhanced Value Index as of the

------

rebalancing date (prior to effecting the rebalancing) will be given priority for the next 50% of constituent security positions. For example, if the fixed number of securities is 100, the buffers are applied between rank 51 and 150. If the target number of MSCI USA Enhanced Value Index constituent securities is not achieved after this step, the highest ranking remaining MSCI USA Index constituent securities are added until the target number is achieved.

*<u>Ongoing Event Related Changes</u>*

The general treatment of corporate events in the MSCI USA Enhanced Value Index aims to minimize turnover outside of index reviews. The methodology aims to appropriately represent an investor's participation in an event based on relevant deal terms and pre-event weighting of the index constituents that are involved. Further, changes in index market capitalization that occur as a result of corporate event implementation will be offset by a corresponding change in the variable weighting factor of the constituent.

Additionally, if the frequency of index reviews in the MSCI USA Index is greater than the frequency of index reviews in the MSCI USA Enhanced Value Index, the changes made to the MSCI USA Index during intermediate index reviews will be neutralized in the MSCI USA Enhanced Value Index.

The following section briefly describes the treatment of common corporate events within the MSCI USA Enhanced Value Index.

No new securities will be added (except where noted below) to the MSCI USA Enhanced Value Index between index reviews. MSCI USA Index deletions will be reflected simultaneously.

---

| | |
|:---|:---|
| **Event Type** | **Event Details** |
| New additions to the MSCI USA Index | A new security added to the MSCI USA Index (such as IPO and other early inclusions) will not be added to the MSCI USA Enhanced Value Index. |
| Spin-Offs | All securities created as a result of the spin-off of an existing MSCI USA Enhanced Value Index constituent will be added to the MSCI USA Enhanced Value Index at the time of event implementation. Reevaluation for continued inclusion in the MSCI USA Enhanced Value Index will occur at the subsequent index review. |
| Merger/acquisition | For mergers and acquisitions, the acquirer's post event weight will account for the proportionate amount of shares involved in deal consideration, while cash proceeds will be invested across the MSCI USA Enhanced Value Index.<br>If an existing MSCI USA Enhanced Value Index constituent is acquired by a security that is not a constituent of the MSCI USA Enhanced Value Index, the existing constituent will be deleted from the MSCI USA Enhanced Value Index and the acquiring non-constituent will not be added to the MSCI USA Enhanced Value Index. |
| Changes in security characteristics | A security will continue to be a constituent of the MSCI USA Enhanced Value Index if there are changes in characteristics (country, sector, size segment, etc.). Reevaluation for continued inclusion in the MSCI USA Enhanced Value Index will occur at the subsequent index review. |

#### iShares<sup>®</sup> MSCI USA Quality Factor ETF
The shares of the iShares<sup>®</sup> MSCI USA Quality Factor ETF (the "ETF") are issued by iShares<sup>®</sup> Trust, a registered investment company.

• The ETF is a tracking ETF that seeks investment results which correspond generally to the price and yield performance, before fees and expenses, of the MSCI USA Sector Neutral Quality Index (the "index").

• The ETF's investment advisor is BlackRock Fund Advisors ("BFA").

• The ETF's shares trade on the Cboe BZX under the ticker symbol "QUAL".

• The iShares<sup>®</sup> Trust's SEC CIK Number is 0001100663.

• The ETF's inception date was July 16, 2013.

• The ETF's shares are issued or redeemed only in creation units of 50,000 shares or multiples thereof.

Effective August 17, 2020, the name of the ETF changed from the iShares<sup>®</sup> Edge MSCI USA Quality Factor ETF to the iShares<sup>®</sup> MSCI USA Quality Factor ETF.

We obtained the following fee information from the iShares*<sup>®</sup>* website without independent verification. The investment advisor is paid a management fee from the ETF based on a percentage of the ETF's average daily net assets, at the annual rate of 0.15%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual ETF operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time. As of December 31, 2022, the aggregate expense ratio of the ETF was 0.15% per annum.

For additional information regarding iShares<sup>®</sup> Trust or BFA, please consult the reports (including the Annual Report to Shareholders on Form N-CSR for the fiscal year ended July 31, 2022) and other information iShares<sup>®</sup> Trust files with the SEC. In addition, information regarding the ETF (including the top ten holdings and weights and sector weights) may be obtained from other sources including, but not limited to, press releases, newspaper articles, other publicly available documents, and the iShares<sup>®</sup> website at us.ishares.com/product_info/fund/overview/QUAL.htm. We are not incorporating by reference the website, the sources listed above or any material they include in this index supplement.

#### Investment Objective
The ETF seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the index. The ETF's investment objective and the index may be changed without the approval of BFA's shareholders.

#### Representative Sampling
BFA uses a representative sampling indexing strategy to manage the ETF. This strategy involves investing in a representative sample of securities that collectively has an investment profile similar to that of the index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the index.

The ETF generally will invest at least 80% of its assets in the component securities of the index and in investments that have economic characteristics that are substantially identical to the component securities of the index (i.e., depositary receipts representing securities of the index) and may invest up to 20% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the index, but which BFA believes will help the ETF track the index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the index. Also, the ETF may lend securities representing up to one-third of the value of the ETF's total assets (including the value of the collateral received).

#### Tracking Error
The performance of the ETF and the index may vary due to a variety of factors, including differences between the securities and other instruments held in the ETF's portfolio and those included in the index, pricing differences, transaction costs incurred by the ETF, the ETF's holding of uninvested cash, differences in timing of the accrual or the valuation of

------

dividends or interest received by the ETF or distributions paid to the ETF's shareholders, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the index or the costs to the ETF of complying with various new or existing regulatory requirements, among other reasons. Tracking error also may result because the ETF incurs fees and expenses, while the index does not. The ETF's use of a representative sampling indexing strategy can be expected to produce a larger tracking error than would result if the ETF used a replication indexing strategy in which an ETF invests in substantially all of the securities in its index in approximately the same proportions as in the index.

#### Industry Concentration Policy
The ETF will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the index is concentrated.

#### MSCI USA Sector Neutral Quality Index
The MSCI USA Sector Neutral Quality Index is designed to measure the performance of securities in the MSCI USA Index that exhibit stronger quality characteristics relative to their peers within the corresponding Global Industry Classification Standard (GICS<sup>®</sup>) sector. The MSCI USA Index includes U.S. large- and mid-capitalization stocks, as defined by MSCI Inc. ("MSCI"). MSCI divides the companies included in the MSCI USA Enhanced Value Index into eleven GICS sectors: Communication Services, Consumer Discretionary, Consumer Staples, Energy, Financials, Health Care, Industrials, Information Technology, Materials, Real Estate and Utilities. For additional information about the MSCI USA Index, please see "iShares<sup>®</sup> MSCI USA Momentum Factor ETF — The MSCI USA Index" above.

The MSCI USA Sector Neutral Quality Index is calculated, published and disseminated daily by MSCI through numerous data vendors, on the MSCI website and in real time on Bloomberg Financial Markets and Reuters Limited. The MSCI USA Sector Neutral Quality Index was launched on December 12, 2014. Additional information about the MSCI USA Sector Neutral Quality Index is available on the following website: msci.com/index-methodology. We are not incorporating by reference the website, the sources listed above or any material they include in this index supplement.

#### Construction of the MSCI USA Sector Neutral Quality Index
To construct the MSCI USA Sector Neutral Quality Index, MSCI selects a predetermined number of constituent securities from the MSCI USA Index based on three main fundamental variables:

(i) high *return on equity* (defined as trailing 12 month earnings per share divided by book value per share),

(ii) low *earnings variability* (defined as standard deviation of year-over-year earnings per share growth over the past five years), and

(iii) low *debt to equity* (defined as total debt to book value).

MSCI uses an algorithm to determine the number of constituent securities to be selected from the MSCI USA Index for inclusion in the MSCI USA Sector Neutral Quality Index with an aim to attain a high exposure to the quality factor while maintaining sufficient market capitalization and number of securities coverage. The number of components is evaluated semi-annually. MSCI assigns weights by multiplying a constituent security's quality score by its market capitalization, as further adjusted to, among others, mitigate the impact of stock-specific risk. Weights in the MSCI USA Sector Neutral Quality Index are next normalized so that sectors in the MSCI USA Sector Neutral Quality Index represent the same relative weight as in the MSCI USA Index, thereby promoting sector neutrality. Additionally, each individual constituent security is capped at 5%.

*<u>Cap/Floor the Variable</u>*

As part of the standardization process, outlier fundamental variable values are capped/floored to ensure that the average values used to standardize the variables are less affected by extreme values. To do this, for a given variable, the values for all securities are first ranked in ascending order within the MSCI USA Index. Missing values are excluded from the ranking. Then, for securities that lie below the 5th percentile rank or above the 95th percentile rank, their value is set equal to the value of the 5th percentile ranked or 95th percentile ranked security, as applicable. This process is repeated for each of the three fundamental variables.

*<u>Calculate the Z-Scores</u>*

After capping/flooring the three fundamental variables within the MSCI USA Index, the z-score with respect to each of the three fundamental variables for each security is calculated using the mean and standard deviation of the relevant variable

------

within the MSCI USA Index. The z-score for each individual security generally measures the extent to which an individual security is an outlier with respect to a particular variable compared to all of the constituent securities included in the MSCI USA Index, measured in terms of standard deviations, and is calculated as follows:

(i) with respect to return on equity, the "z-score" *equals* (i) (a) the capped/floored return on equity for such security *minus* (b) the mean of the capped/floored returns on equity for all of the securities in the MSCI USA Index *divided* by (ii) the standard deviation of the capped/floored returns on equity for the securities in the MSCI USA Index; and

(ii) with respect to debt to equity and earnings variability, the "z-score" *equals* the negative (to ensure securities of companies with higher debt to equity or higher variable earnings are ranked lower) of (i) (a) the capped/floored debt to equity/earnings variability for such security *minus* (b) the mean of the capped/floored debt to equity/earnings variability for all of the securities in the MSCI USA Index *divided* by (ii) the standard deviation of the capped/floored debt to equity/earnings variability for the securities in the MSCI USA Index.

*<u>Calculate the Quality Score</u>*

After standardizing each of the three variable values for each security and calculating z-scores with respect to each of the three fundamental variables, a "composite quality z-score" for each security is computed by averaging the z-scores of the three fundamental variables. Computation of the composite quality z-score also depends on the availability of fundamental variables, as described below.

---

| | | |
|:---|:---|:---|
| **Case** | **Detail** | **Action** |
| Case 1 | return on equity is missing | If return on equity is missing, composite quality z-score is not calculated and the security will not be part of the MSCI USA Sector Neutral Quality Index |
| Case 2 | debt to equity is missing, but other two variables are available | composite quality z-score is calculated using return on equity and earnings variability z-scores |
| Case 3 | earnings variability is missing, but other two variables are available | composite quality z-score is calculated using return on equity and debt to equity z-scores |
| Case 4 | debt to equity and earnings variability are missing but return on equity is available | composite quality z-score is not calculated and the security will not be part of the MSCI USA Sector Neutral Quality Index |
| Case 5 | All three variables are missing | Security will not be part of the MSCI USA Sector Neutral Quality Index |

---

The "quality score" is then computed from the composite quality z-score as follows:

(i) If the composite quality z-score is *greater than* 0, the quality score equals 1 *plus* the composite quality z-score; or

(ii) If the composite quality z-score is *less than* 0, the quality score equals the *quotient* of (i) 1 *divided* by (ii) the *difference* of 1 *minus* the composite quality z-score

*<u>Security Selection</u>*

In order to be selected for inclusion in the MSCI USA Sector Neutral Quality Index, a constituent security's quality score must rank among the highest quality scores in the MSCI USA Index. The number of securities targeted for inclusion in the MSCI USA Sector Neutral Quality Index at initial construction and upon each rebalancing is then determined based on certain rules relating to free-float market capitalization (market price per share multiplied by the number of shares held by non-controlling interests) and numbers of constituent securities as described below.

*Initial Construction. The number of securities targeted for inclusion in the MSCI USA Sector Neutral Quality Index at initial construction (or on any semi-annual rebalancing when the initial construction methodology is required to be applied, as described below under the caption "—Rebalancing") is determined by (i) ranking each constituent security in the MSCI USA Index according to its quality score (using such securities' weights in the MSCI USA Index if multiple securities have the same score) and (ii) applying the following rules in order of priority:*

• if the MSCI USA Index has 25 or fewer constituent securities on the relevant date, each constituent security in the MSCI USA Index is included as a constituent security in the MSCI USA Sector Neutral Quality Index; or

------

• if 25 or fewer of the highest ranking MSCI USA Index constituent securities account for at least 30% of the MSCI USA Index's free-float market capitalization, the target number of Quality Index constituent securities will be 25, subject to the rounding rules; or

• if 25 of the highest ranking MSCI USA Index constituent securities do <u>not</u> account for at least 30% of the MSCI USA Index's free-float market capitalization, but the top 10% of the highest ranking MSCI USA Index constituent securities <u>do</u> account for at least 30% of the MSCI USA Index's free-float market capitalization, the number of constituent securities constituting the top 10% of the highest ranking MSCI USA Index constituent securities, after rounding, is the number of securities targeted for inclusion in the MSCI USA Sector Neutral Quality Index; or

• if the number of top ranking MSCI USA Index constituent securities accounting for 30% of the MSCI USA Index's free-float market capitalization, after rounding, account for less than 40% of the total number of MSCI USA Index constituent securities, such rounded number is the number of securities targeted for inclusion in the MSCI USA Sector Neutral Quality Index; or

• if the number of top ranking MSCI USA Index constituent securities accounting for 30% of the MSCI USA Index's free-float market capitalization, after rounding, account for 40% or more of the total number of MSCI USA Index constituent securities, eliminate each of the lowest ranking MSCI USA Index constituent securities from such rounded number until the number of those remaining account for 40% or less of the total number of MSCI USA Index constituent securities; and

o if the remaining MSCI USA Index constituent securities account for at least 20% of the MSCI USA Index's free-float market capitalization, the number of such remaining MSCI USA Index constituent securities, after rounding, is the number of securities targeted for inclusion in the MSCI USA Sector Neutral Quality Index; or

o if the remaining MSCI USA Index constituent securities account for less than 20% of the MSCI USA Index's free-float market capitalization, add back the next highest ranking MSCI USA Index constituent securities previously eliminated until the MSCI USA Sector Neutral Quality Index's constituent securities account for at least 20% of the MSCI USA Index's public float and such number of MSCI USA Index constituent securities, after rounding, is the number of securities targeted for inclusion in the MSCI USA Sector Neutral Quality Index.

Where indicated above, the following rounding conventions apply:

• if the number of constituent securities is less than 100, round to the nearest 10 constituent securities;

• if the number of constituent securities is greater than or equal to 100 but less than 300, round to the nearest 25 constituent securities; and

• if the number of constituent securities is greater than or equal to 300, round to the nearest 50 constituent securities.

*Rebalancing. The target number of securities for inclusion in the MSCI USA Sector Neutral Quality Index at each semi-annual rebalancing is determined by applying the following rules in order of priority:*

• if the target number of MSCI USA Sector Neutral Quality Index constituent securities on the immediately *preceding* rebalancing date or initial construction (following rebalancing or construction) exceeds the number of MSCI USA Index constituent securities on the rebalancing date, the initial construction methodology described above should be applied to determine the number of constituent securities to be included in the MSCI USA Sector Neutral Quality Index; or

• if the MSCI USA Index has 25 or fewer constituent securities on the rebalancing date, each constituent security in the MSCI USA Index is included as a constituent security in the MSCI USA Sector Neutral Quality Index; or

• if the number of constituent securities included in the MSCI USA Index on the immediately *preceding* rebalancing or initial construction date (following rebalancing or construction) is less than 25, repeat the initial construction process described above to determine the number of constituent securities to be included in the MSCI USA Sector Neutral Quality Index; or

• if the constituent securities of the MSCI USA Sector Neutral Quality Index determined on the rebalancing or initial construction date (following rebalancing or construction) immediately *preceding* the semi-annual rebalancing date account for less than 10% of the MSCI USA Index's free-float market capitalization on the current rebalancing date, repeat the initial construction process described above to determine the constituent securities to be included in the MSCI USA Sector Neutral Quality Index; or

• otherwise, the target number of MSCI USA Sector Neutral Quality Index constituent securities will not change from the immediately preceding rebalancing or construction date (following rebalancing or construction).

#### Weighting Scheme
The securities selected in the previous step are assigned weights in proportion to their market capitalization weight in the MSCI USA Index and quality score. These weights are then updated to implement sector neutrality (i.e., the weight of each sector in the MSCI USA Sector Neutral Quality Index is equated with the weight of that sector in the MSCI USA Index). This is done by normalizing the weights of the constituents within each sector to reflect the effective MSCI USA Index sector weight. If no securities are selected from any particular sector(s) of the MSCI USA Index to the MSCI Sector Neutral Quality Index during rebalancing, the proforma weight of that sector in the MSCI USA Index will be re-distributed amongst remaining sectors of the MSCI Sector Neutral Quality Index. Additionally, each individual constituent security is capped at 5%.

#### Maintenance of the MSCI USA Sector Neutral Quality Index
The MSCI USA Sector Neutral Quality Index is rebalanced semi-annually and the changes from the rebalancing are made as of the close of the last business day of each May and November, to coincide with the semi-annual index reviews of the MSCI USA Index. The pro forma MSCI USA Sector Neutral Quality Index is generally announced nine business days before the effective date.

*<u>Buffer Rules</u>*

In selecting securities for inclusion in the MSCI USA Sector Neutral Quality Index on any rebalancing date, certain buffer rules are applied to maintain continuity and reduce turnover in constituent securities. Although 80% of the positions in the rebalancing will be selected from among the highest ranking MSCI USA Index constituent securities without regard to whether they are currently included in the MSCI USA Sector Neutral Quality Index, existing constituent securities of the MSCI USA Sector Neutral Quality Index as of the rebalancing date (prior to effecting the rebalancing) will be given priority for the next 20% of constituent security positions. If the target number of Quality Index constituent securities is not achieved after this step, the highest ranking remaining MSCI USA Index constituent securities are added until the target number is achieved.

*<u>Ongoing Event Related Changes</u>*

The general treatment of corporate events in the MSCI USA Sector Neutral Quality Index aims to minimize turnover outside of index reviews. The methodology aims to appropriately represent an investor's participation in an event based on relevant deal terms and pre-event weighting of the index constituents that are involved. Further, changes in index market capitalization that occur as a result of corporate event implementation will be offset by a corresponding change in the variable weighting factor of the constituent.

Additionally, if the frequency of index reviews in the MSCI USA Index is greater than the frequency of index reviews in the MSCI USA Sector Neutral Quality Index, the changes made to the MSCI USA Index during intermediate index reviews will be neutralized in the MSCI USA Sector Neutral Quality Index.

The following section briefly describes the treatment of common corporate events within the MSCI USA Sector Neutral Quality Index.

No new securities will be added (except where noted below) to the MSCI USA Sector Neutral Quality Index between index reviews. MSCI USA Index deletions will be reflected simultaneously.

|:---|:---|
| **Event Type** | **Event Details** |
| New additions to the MSCI USA Index | A new security added to the MSCI USA Index (such as IPO and other early inclusions) will not be added to the MSCI USA Sector Neutral Quality Index. |
| Spin-Offs | All securities created as a result of the spin-off of an existing MSCI USA Sector Neutral Quality Index constituent will be added to the MSCI USA Sector Neutral Quality Index at the time of event implementation. Reevaluation for continued inclusion in the MSCI USA Sector Neutral Quality Index will occur at the subsequent index review. |
| Merger/acquisition | For mergers and acquisitions, the acquirer's post event weight will account for the proportionate amount of shares involved in deal consideration, while cash proceeds will be invested across the MSCI USA Sector Neutral Quality Index.<br> If an existing MSCI USA Sector Neutral Quality Index constituent is acquired by a security that is not a constituent of the MSCI USA Sector Neutral Quality Index, the existing constituent will be deleted from the MSCI USA Sector Neutral Quality Index and the acquiring non-constituent will not be added to the MSCI USA Sector Neutral Quality Index. |

#### iShares<sup>®</sup> MSCI USA Size Factor ETF
The shares of the iShares<sup>®</sup> MSCI USA Size Factor ETF (the "ETF") are issued by iShares<sup>®</sup> Trust, a registered investment company.

• The ETF is a tracking ETF that seeks investment results which correspond generally to the price and yield performance, before fees and expenses, of the MSCI USA Low Size Index (the "index"). Prior to December 3, 2018, the ETF tracked the MSCI USA Risk Weighted Index. The inception date of the index was September 11, 2018.

• The ETF's investment advisor is BlackRock Fund Advisors ("BFA").

• The ETF's shares trade on the NYSE Arca under the ticker symbol "SIZE".

• The iShares<sup>®</sup> Trust's SEC CIK Number is 0001100663.

• The ETF's inception date was April 16, 2013.

• The ETF's shares are issued or redeemed only in creation units of 50,000 shares or multiples thereof.

Effective August 17, 2020, the name of the ETF changed from the iShares<sup>®</sup> Edge MSCI USA Size Factor ETF to the iShares<sup>®</sup> MSCI USA Size Factor ETF.

We obtained the following fee information from the iShares*<sup>®</sup>* website without independent verification. The investment advisor is paid a management fee from the ETF based on a percentage of the ETF's average daily net assets, at the annual rate of 0.15%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual ETF operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time. As of December 31, 2022, the aggregate expense ratio of the ETF was 0.15% per annum.

For additional information regarding iShares<sup>®</sup> Trust or BFA, please consult the reports (including the Annual Report to Shareholders on Form N-CSR for the fiscal year ended July 31, 2022) and other information iShares<sup>®</sup> Trust files with the SEC. In addition, information regarding the ETF (including the top ten holdings and weights and sector weights) may be obtained from other sources including, but not limited to, press releases, newspaper articles, other publicly available documents, and the iShares<sup>®</sup> website at us.ishares.com/product_info/fund/overview/SIZE.htm. We are not incorporating by reference the website, the sources listed above or any material they include in this index supplement.

#### Investment Objective
The ETF seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the index. The ETF's investment objective and the index may be changed without the approval of BFA's shareholders.

#### Representative Sampling
BFA uses a representative sampling indexing strategy to manage the ETF. This strategy involves investing in a representative sample of securities that collectively has an investment profile similar to that of the index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the index.

The ETF generally will invest at least 80% of its assets in the component securities of the index and in investments that have economic characteristics that are substantially identical to the component securities of the index (i.e., depositary receipts representing securities of the index) and may invest up to 20% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the index, but which BFA believes will help the ETF track the index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the index. Also, the ETF may lend securities representing up to one-third of the value of the ETF's total assets (including the value of the collateral received).

#### Tracking Error
The performance of the ETF and the index may vary due to a variety of factors, including differences between the securities and other instruments held in the ETF's portfolio and those included in the index, pricing differences, transaction costs incurred by the ETF, the ETF's holding of uninvested cash, differences in timing of the accrual or the valuation of

------

dividends or interest received by the ETF or distributions paid to the ETF's shareholders, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the index or the costs to the ETF of complying with various new or existing regulatory requirements, among other reasons. Tracking error also may result because the ETF incurs fees and expenses, while the index does not. The ETF's use of a representative sampling indexing strategy can be expected to produce a larger tracking error than would result if the ETF used a replication indexing strategy in which an ETF invests in substantially all of the securities in its index in approximately the same proportions as in the index.

#### Industry Concentration Policy
The ETF will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the index is concentrated.

#### MSCI USA Low Size Index
The MSCI USA Low Size Index is designed to emphasize the stock performance of small market-capitalization companies included in a traditional market capitalization weighted parent index, the MSCI USA Index. The MSCI USA Index includes U.S. large- and mid-capitalization stocks, as defined by MSCI, Inc. ("MSCI"). For additional information about the MSCI USA Index, please see "iShares<sup>®</sup> MSCI USA Momentum Factor ETF — The MSCI USA Index" above.

The MSCI USA Low Size Index is calculated, published and disseminated daily by MSCI through numerous data vendors, on the MSCI website and in real time on Bloomberg Financial Markets and Reuters Limited. The MSCI USA Low Size Index was launched on September 11, 2018. Additional information about the MSCI USA Low Size Index is available on the following website: msci.com/index-methodology. We are not incorporating by reference the website, the sources listed above or any material they include in this index supplement.

#### Construction of the MSCI USA Low Size Index
The MSCI USA Low Size Index is constructed by applying a mathematical formula at each rebalancing that reweights the components of its market capitalization-weighted MSCI USA Index, such that the representation of smaller capitalization companies is increased relative to larger capitalization companies (by assigning weights in the inverse proportion of natural logarithm of total issuer market capitalization of the constituents of the MSCI USA Index). In addition, at each rebalancing, MSCI calculates a "constraint factor" for each component. The constraint factor is the ratio of the component's weight in the MSCI USA Low Size Index to that component's weight in the MSCI USA Index. The constraint factor is held constant between each index review, except in the case of certain corporate events, as defined by MSCI. Changes in the relative weight of an individual component in the MSCI USA Index due to market appreciation/depreciation result in that component increasing/decreasing in weight in the MSCI USA Low Size Index to hold the constraint factor for that component constant between each rebalancing.

#### Maintenance of the MSCI USA Low Size Index
The MSCI USA Low Size Index is rebalanced semi-annually and the changes from the rebalancing are made as of the close of the last business day of each May and November, to coincide with the semi-annual index reviews of the MSCI USA Index. The pro forma MSCI USA Low Size Index is generally announced nine business days before the effective date.

#### MSCI USA Minimum Volatility Index
The MSCI USA Minimum Volatility Index is designed to measure the performance of securities in the MSCI USA Index that, in the aggregate, have lower volatility relative to the large- and mid-cap U.S. equity market. The MSCI USA Index includes U.S. large- and mid-capitalization stocks, as defined by MSCI, Inc. ("MSCI"). For additional information about the MSCI USA Index, please see "iShares<sup>®</sup> MSCI USA Momentum Factor ETF — The MSCI USA Index" above. MSCI divides the companies included in the MSCI USA Minimum Volatility Index into eleven GICS sectors: Communication Services, Consumer Discretionary, Consumer Staples, Energy, Financials, Health Care, Industrials, Information Technology, Materials, Real Estate and Utilities.

The MSCI USA Minimum Volatility Index is calculated, published and disseminated daily by MSCI through numerous data vendors, on the MSCI website and in real time on Bloomberg Financial Markets and Reuters Limited. The MSCI USA Minimum Volatility Index was launched on June 2, 2008. Additional information about the MSCI USA Minimum Volatility Index is available on the following website: msci.com/index-methodology, which we are not incorporating by reference in this index supplement.

#### Construction of the MSCI USA Minimum Volatility Index
The MSCI USA Minimum Volatility Index seeks to optimize the MSCI USA Index, in U.S. dollars, for the lowest absolute risk within a given set of constraints: (i) minimum and maximum component weights, (ii) limitations on divergence in sector representation and non-volatility related factor exposures between the MSCI USA Minimum Volatility Index and the MSCI USA Index and (iii) turnover in the MSCI USA Minimum Volatility Index.

Details about the Barra multi-factor risk models are available at msci.com/portfolio-management, which we are not incorporating by reference in this index supplement

At each semi-annual index review, the following optimization constraints are employed, which aim to ensure replicability and investability while achieving the lowest volatility for a given set of constraints.

• The maximum weight of an index constituent will be restricted to the lower of 1.5% or 20 times the weight of the security in the MSCI USA Index.

• The minimum weight of an index constituent will be 0.05%.

• The sector weights of the MSCI USA Minimum Volatility Index will not deviate more than +/-5% from the sector weights of the MSCI USA Index. MSCI divides the companies included in the MSCI USA Minimum Volatility Index into eleven GICS sectors: Communication Services, Consumer Discretionary, Consumer Staples, Energy, Financials, Health Care, Industrials, Information Technology, Materials, Real Estate and Utilities.

• No constraint will be applied on the exposure of the MSCI USA Minimum Volatility Index to volatility-related risk index factors (beta volatility and residual volatility). Exposure to all other risk index factors will be restricted to +/-0.25 standard deviations relative to the MSCI USA Index.

• The one way turnover of the MSCI USA Minimum Volatility Index is constrained to a maximum of 10%.

The MSCI USA Minimum Volatility Index is constructed using the Barra Optimizer in combination with the relevant Barra Equity Model. The optimization uses the MSCI USA Index as the universe of eligible securities and the specified optimization objective and constraints to determine the optimal MSCI USA Minimum Volatility Index. The Barra Optimizer determines the optimal solution, i.e. the portfolio with the lowest total risk, using an estimated security co-variance matrix under the applicable investment constraints. The MSCI USA Minimum Volatility Index seeks to have the lowest absolute volatility based on the set of constraints.

*<u>Optimization Settings</u>*

The MSCI USA Minimum MSCI USA Minimum Volatility Index is constructed using the Barra Optimizer in combination with the relevant Barra Equity Model. The following optimization settings are applied to construct the MSCI USA Minimum Volatility Index.

------

*Specify "Initial Portfolio" and "Trade Universe" settings on the Barra Optimizer*

• "Initial portfolio" is set as the current MSCI USA Minimum Volatility Index, using the constituent weights as of the close of the rebalancing date (before the rebalancing) updated for corporate actions up to the effective date of the rebalancing. When there is no current MSCI USA Minimum Volatility Index (for example, when no optimization has been applied to the MSCI USA Index yet), the initial portfolio is set to be to the MSCI USA Index.

• "Trade universe" is set to be the index constituents of the MSCI USA Index.

*Specify Risk Model*

• The factor exposures for all the securities in the trade universe are set using the most recent monthly release of factor exposure data of the relevant Barra Equity Model.

• The common factor co-variances are set using the most recent monthly release of factor co-variance data of the relevant Barra Equity Model.

• The specific co-variances of all securities in the trade universe are set using the most recent monthly release of specific co-variances data of the relevant Barra Equity Model.

*Setup Utility function*

• The optimization objective is to find a pro forma MSCI USA Minimum Volatility Index that minimizes the total risk of MSCI USA Index, as determined by the relevant Barra Equity Model. The risk aversion parameters used in the optimization are as follows:

o Common factor risk aversion = 0.0075

o Specific risk aversion = 0.075

*Setup Constraints for Initial Construction*

• The maximum weight of an index constituent will be restricted to the lower of 1.5% or 20 times the weight of the security in the MSCI USA Index.

• The minimum weight of an index constituent will be 0.05%.

• The sector weights of the MSCI USA Minimum Volatility Index will not deviate more than +/-5% from the sector weights of the MSCI USA Index.

• No constraint will be applied on the exposure of the MSCI USA Minimum Volatility Index to the Beta and Residual Volatility risk index factors. Exposure to all other risk index factors will be restricted to +/-0.25 standard deviations relative to the MSCI USA Index.

*Additional Setup constraints for Semi-Annual Index Reviews*

• The one way turnover of the MSCI USA Minimum Volatility Index is constrained to a maximum of 10%

*<u>Handling Indefeasible Optimizations</u>*

During the semi-annual index review, in the event that there is no optimal solution that satisfies all the optimization constraints defined above, the following constraints will be relaxed, until an optimal solution is found:

• Relax the turnover constraint in steps of 5%, up to a maximum of 30%

• Relax the minimum weight constraint in steps of 0.01% up to a minimum of 0.01%.

In the event that no optimal solution is found after the above constraints have been relaxed, the MSCI USA Minimum Volatility Index will not be rebalanced for that semi-annual index review.

#### Maintenance of the MSCI USA Minimum Volatility Index
The MSCI USA Minimum Volatility Index is rebalanced semi-annually and the changes from the rebalancing are made as of the close of the last business day of each May and November, to coincide with the semi-annual index reviews of the MSCI USA Index. The pro forma MSCI USA Minimum Volatility Index is generally announced nine business days before the effective date.

The security co-variance matrix used to determine the MSCI USA Minimum Volatility Index is maintained on a monthly basis. For the May and the November semi-annual MSCI USA Minimum Volatility Index reviews, the security covariance matrices as of the end of April and the end of October are used respectively.

------

At each rebalancing, a constraint factor is calculated for each constituent in the MSCI USA Minimum Volatility Index. The constraint factor is defined as the weight in the MSCI USA Minimum Volatility Index at the time of the rebalancing divided by the weight in the MSCI USA Index. The constraint factor as well as the constituents in the index remains constant between index reviews except in case of corporate events as described below.

*<u>Ongoing Event Related Changes</u>*

The general treatment of corporate events in the MSCI USA Minimum Volatility Index aims to minimize turnover outside of index reviews. The methodology aims to appropriately represent an investor's participation in an event based on relevant deal terms and pre-event weighting of the index constituents that are involved. Further, changes in index market capitalization that occur as a result of corporate event implementation will be offset by a corresponding change in the variable weighting factor of the constituent.

Additionally, if the frequency of index reviews in the MSCI USA Index is greater than the frequency of index reviews in the MSCI USA Minimum Volatility Index, the changes made to the MSCI USA Index during intermediate index reviews will be neutralized in the MSCI USA Minimum Volatility Index.

The following section briefly describes the treatment of common corporate events within the MSCI USA Minimum Volatility Index.

No new securities will be added (except where noted below) to the MSCI USA Minimum Volatility Index between index reviews. MSCI USA Index deletions will be reflected simultaneously.

---

| | |
|:---|:---|
| **Event Type** | **Event Details** |
| New additions to the MSCI USA Index | A new security added to the MSCI USA Index (such as IPO and other early inclusions) will not be added to the index. |
| Spin-Offs | All securities created as a result of the spin-off of an existing MSCI USA Minimum Volatility Index constituent will be added to the MSCI USA Minimum Volatility Index at the time of event implementation. Reevaluation for continued inclusion in the MSCI USA Minimum Volatility Index will occur at the subsequent index review. |
| Merger/acquisition | For mergers and acquisitions, the acquirer's post event weight will account for the proportionate amount of shares involved in deal consideration, while cash proceeds will be invested across the MSCI USA Minimum Volatility Index.<br>If an existing MSCI USA Minimum Volatility Index constituent is acquired by a security that is not a constituent of the MSCI USA Minimum Volatility Index, the existing constituent will be deleted from the MSCI USA Minimum Volatility Index and the acquiring non-constituent will not be added to the MSCI USA Minimum Volatility Index. |
| Changes in security characteristics | A security will continue to be a constituent of the MSCI USA Minimum Volatility Index if there are changes in characteristics (country, sector, size segment, etc.). Reevaluation for continued inclusion in the MSCI USA Minimum Volatility Index will occur at the subsequent index review. |

#### iShares <sup>®</sup> 1-3 Year Treasury Bond ETF
The shares of the iShares<sup>®</sup> 1-3 Year Treasury Bond ETF (the "ETF") are issued by iShares<sup>®</sup> Trust, a registered investment company.

● The ETF is a tracking ETF that seeks investment results which correspond generally to the price and yield performance, before fees and expenses, of the ICE U.S. Treasury 1-3 Year Bond Index (the "index").

● The ETF's investment advisor is BlackRock Fund Advisors ("BFA").

● The ETF's shares trade on the Nasdaq under the ticker symbol "SHY".

● The iShares<sup>®</sup> Trust's SEC CIK Number is 0001100663.

● The ETF's inception date was July 22, 2002.

● The ETF's shares are issued or redeemed only in creation units of 100,000 shares or multiples thereof.

We obtained the following fee information from the iShares<sup>®</sup> website without independent verification. The investment advisor is paid a management fee from the ETF based on a percentage of the ETF's average daily net assets, at an annual rate of 0.15%. BFA is responsible for substantially all expenses of the ETF, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses. As of December 31, 2022, the expense ratio of the ETF was 0.15% per annum.

For additional information regarding iShares<sup>®</sup> Trust or BFA, please consult the reports (including the Semi-Annual Report to Shareholders on Form N-CSRS for the period ended August 31, 2022) and other information iShares<sup>®</sup> Trust files with the SEC. In addition, information regarding the ETF (including the top ten holdings and weights) may be obtained from other sources including, but not limited to, press releases, newspaper articles, other publicly available documents, and the iShares<sup>®</sup> website at us.ishares.com/product_info/fund/overview/SHY.htm. We are not incorporating by reference the website, the sources listed above or any material they include in this index supplement.

#### Investment Objective and Strategy
The ETF seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the index. The ETF's investment objective and the index that the ETF tracks may be changed without shareholder approval.

BFA uses a representative sampling indexing strategy to attempt to track the performance of the index. For the ETF, this strategy involves investing in a representative sample of securities that collectively have an investment profile similar to that of the index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and industry weightings), fundamental characteristics (such as return variability, duration, maturity or credit ratings and yield) and liquidity measures similar to those of the index. The ETF may or may not hold all of the securities in the index.

The ETF will invest at least 80% of its assets in the component securities of the index, and the ETF will invest at least 90% of its assets in U.S. Treasury securities that BFA believes will help the ETF track the index. The ETF will invest no more than 10% of its assets in futures, options and swaps contracts that BFA believes will help the ETF track the index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for purposes of calculating the percentage of investments included in the index. The ETF may lend securities representing up to one-third of the value of the ETF's total assets (including the value of the collateral received).

------

#### Tracking Error
The performance of the ETF and the index may vary due to a variety of factors, including differences between the securities held in the ETF's portfolio and those included in the index, pricing differences, transaction costs incurred by the ETF, the ETF holding uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptances of custom baskets, changes to the index or the costs to the ETF of complying with new or existing regulatory requirements, among other reasons. Tracking error also may result because the ETF incurs fees and expenses, while the index does not. The ETF's use of a representative sampling indexing strategy can be expected to produce a larger tracking error than would result if the ETF used a replication indexing strategy in which an ETF invests in substantially all of the securities in its index in approximately the same proportions as in the index.

#### ICE U.S. Treasury 1-3 Year Bond Index
The index is sponsored by ICE Data Indices, LLC ("IDI"). The index is market capitalization weighted and is designed to track the performance of U.S. dollar denominated, fixed rate treasuries with a minimum term to maturity greater than or equal to one year and less than three years.

*Eligibility Criteria and Inclusion Rules*

Qualifying securities must have greater than or equal to one year and less than three years remaining term to final maturity as of the rebalancing date, a fixed coupon schedule and an adjusted amount outstanding of at least $300 million. The amount outstanding for all qualifying securities is adjusted by subtracting the amounts held by the Federal Reserve's System Open Market Account (the "adjusted amount outstanding"). Bills, inflation-linked debt, original issue zero coupon securities and STRIPs are excluded from the index; however, the amounts outstanding of qualifying coupon securities are not reduced by any portions that have been stripped. Agency debt with or without a U.S. Government guarantee and securities issued or marketed primarily to retail investors do not qualify for inclusion in the index.

*Index Calculation*

The total market value of the index at any time is the sum of the market value of each constituent plus any intra-month cash from coupon payments or principal repayments and the weight for the constituent.

The market value of a constituent is based on the adjusted amount outstanding. Cash flows from bond payments and redemptions are retained in the index until the end of the month and then are removed as part of the rebalancing. Cash does not earn any reinvestment income while it is held in the index.

Calculations are performed daily, using bid prices at 3 p.m. Eastern Time.

*Index Maintenance*

The index is rebalanced on the last calendar day of the month, based on information available up to and including the third business day before the last business day of the month. New issues must be auctioned on or before the calendar month end rebalancing date in order to qualify for the coming month. No changes are made to constituent holdings other than on month end rebalancing dates.

#### USE OF PROCEEDS
We intend to lend the net proceeds from the sale of the notes to The Goldman Sachs Group, Inc. or its affiliates.

We or our affiliates may also use those proceeds in transactions intended to hedge our obligations under the offered notes as described below.

#### HEDGING
In anticipation of the sale of the notes, we and/or our affiliates have entered into, or expect to enter into, hedging transactions involving purchases of listed or over-the-counter options, futures and/or other instruments linked to the index, the underlying assets or SOFR on or before the trade date. In addition, from time to time after we issue the notes, we and/or our affiliates expect to enter into additional hedging transactions and to unwind those we have entered into, in connection with the notes and perhaps in connection with other index-linked notes we issue, some of which may have returns linked to the index, the underlying assets or SOFR. Consequently, with regard to your notes, from time to time, we and/or our affiliates:

● may take or dispose of positions in the assets held by the ETFs,

● may take or dispose of positions in interest rate swaps, options swaps and treasury bonds.

We and/or our affiliates may acquire a long or short position in securities similar to your notes from time to time and may, in our or their sole discretion, hold or resell those securities.

In the future, we and/or our affiliates expect to close out hedge positions relating to the notes and perhaps relating to other notes with returns linked to the index, the underlying assets, SOFR or assets held by the ETFs. We expect our affiliates' steps to involve sales of instruments linked to the index, the underlying assets, SOFR or assets held by the ETFs on or shortly before the determination date. Our affiliates' steps also may involve sales and/or purchases of some or all of the listed or over-the-counter options, futures or other instruments linked to the index.

#### EMPLOYEE RETIREMENT INCOME SECURITY ACT
*This section is only relevant to you if you are an insurance company or the fiduciary of a pension plan or an employee benefit plan (including a governmental plan, an IRA or a Keogh Plan) proposing to invest in the notes.*

The U.S. Employee Retirement Income Security Act of 1974, as amended ("ERISA") and the U.S. Internal Revenue Code of 1986, as amended (the "Code"), prohibit certain transactions ("prohibited transactions") involving the assets of an employee benefit plan that is subject to the fiduciary responsibility provisions of ERISA or Section 4975 of the Code (including individual retirement accounts, Keogh plans and other plans described in Section 4975(e)(1) of the Code) (a "Plan") and certain persons who are "parties in interest" (within the meaning of ERISA) or "disqualified persons" (within the meaning of the Code) with respect to the Plan; governmental plans may be subject to similar prohibitions unless an exemption applies to the transaction. The assets of a Plan may include assets held in the general account of an insurance company that are deemed "plan assets" under ERISA or assets of certain investment vehicles in which the Plan invests. Each of The Goldman Sachs Group, Inc. and certain of its affiliates may be considered a "party in interest" or a "disqualified person" with respect to many Plans, and, accordingly, prohibited transactions may arise if the notes are acquired by or on behalf of a Plan unless those notes are acquired and held pursuant to an available exemption. In general, available exemptions include: transactions effected on behalf of that Plan by a "qualified professional asset manager" (prohibited transaction exemption 84-14) or an "in-house asset manager" (prohibited transaction exemption 96- 23), transactions involving insurance company general accounts (prohibited transaction exemption 95-60), transactions involving insurance company pooled separate accounts (prohibited transaction exemption 90-1), transactions involving bank collective investment funds (prohibited transaction exemption 91-38) and transactions with service providers under Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code where the Plan receives no less and pays no more than "adequate consideration" (within the meaning of Section 408(b)(17) of ERISA and Section 4975(f)(10) of the Code). The person making the decision on behalf of a Plan or a governmental plan shall be deemed, on behalf of itself and the plan, by purchasing and holding the notes, or exercising any rights related thereto, to represent that (a) the plan will receive no less and pay no more than "adequate consideration" (within the meaning of Section 408(b)(17) of ERISA and Section 4975(f)(10) of the Code) in connection with the purchase and holding of the notes, (b) none of the purchase, holding or disposition of the notes or the exercise of any rights related to the notes will result in a non-exempt prohibited transaction under ERISA or the Code (or, with respect to a governmental plan, under any similar applicable law or regulation), and (c) neither The Goldman Sachs Group, Inc. nor any of its affiliates is a "fiduciary" (within the meaning of Section 3(21) of ERISA or, with respect to a governmental plan, under any similar applicable law or regulation) with respect to the purchaser or holder in connection with such person's acquisition, disposition or holding of the notes, or as a result of any exercise by The Goldman Sachs Group, Inc. or any of its affiliates of any rights in connection with the notes, and neither The Goldman Sachs Group, Inc. nor any of its affiliates has provided investment advice in connection with such person's acquisition, disposition or holding of the notes.

*If you are an insurance company or the fiduciary of a pension plan or an employee benefit plan (including a governmental plan, an IRA or a Keogh plan) and propose to invest in the notes, you should consult your legal counsel.*<br>

All applicable provisions of the FSMA must be complied with in respect to anything done by any person in relation to the notes in, from or otherwise involving the United Kingdom.
