#### BLACKROCK LARGE CAP SERIES FUNDS, INC.
BlackRock Advantage Large Cap Value Fund (the "Fund")

#### Supplement dated May 21, 2026 to the Summary Prospectuses, Prospectuses and Statement of

#### Additional Information of the Fund, each dated September 26, 2025, as supplemented to date
At a meeting held on May 19, 2026, the Board of Directors (the "Board") of BlackRock Large Cap Series Funds, Inc. (the "Corporation"), on behalf of the Fund, approved the Reorganization (as defined below) of the Fund into an exchange-traded fund ("ETF"), which will be managed by BlackRock Fund Advisors, an investment adviser under common control with BlackRock Advisors, LLC, the Fund's current investment adviser ("BlackRock"). The Board, including all of the Directors who are not "interested persons" (as defined in the Investment Company Act of 1940, as amended) of the Corporation, determined, with respect to the Reorganization, that participation in the Reorganization is in the best interests of the Fund and the interests of existing shareholders of the Fund will not be diluted as a result of the Reorganization.

The Fund will be reorganized into an ETF through the reorganization of the Fund into a newly-created ETF, iShares Enhanced Large Cap Value Active ETF (the "Acquiring Fund"), which is a series of BlackRock ETF Trust. The Fund and the Acquiring Fund have identical investment objectives and fundamental investment policies, and similar investment strategies. The Acquiring Fund is expected to seek to pursue its investment objective while seeking to maintain a low tracking error to the Russell 1000<sup>®</sup> Value Index. The Acquiring Fund's investment strategies will be further described in a combined prospectus/information statement that will be included in a registration statement on Form N-14 that will be filed with the Securities and Exchange Commission (the "SEC").

Following the reorganization, the Fund will be liquidated (such reorganization and liquidation, the "Reorganization").

The Reorganization is anticipated to close as of the close of trading on the New York Stock Exchange on November 20, 2026. The Acquiring Fund has not commenced investment operations, and it is anticipated that the Acquiring Fund will not have shareholders prior to the Reorganization.

**Importantly, in order to receive shares of the Acquiring Fund as part of the Reorganization, Fund shareholders must hold their shares of the Fund through a brokerage account that can accept shares of an ETF (the Acquiring Fund). If Fund shareholders do not hold their shares of the Fund through an eligible brokerage account, they will not receive shares of the Acquiring Fund as part of the Reorganization. For Fund shareholders that do not currently hold their shares of the Fund through a brokerage account that can hold shares of the Acquiring Fund, please see the Q&A that follows for additional actions that such Fund shareholders must take to receive shares of the Acquiring Fund as part of the Reorganization. No further action is required for Fund shareholders that hold shares of the Fund through a brokerage account that can hold shares of the Acquiring Fund.**

BlackRock believes that the Reorganization will provide multiple benefits for investors of the Fund, including lower net expenses, additional trading flexibility, increased portfolio holdings transparency, and the potential for increased tax efficiency.

The Reorganization will be conducted pursuant to an Agreement and Plan of Reorganization (the "Plan"). The Reorganization is intended to qualify as a tax-free reorganization under Section 368(a) of the U.S. Internal Revenue Code of 1986, as amended. As a result, Fund shareholders generally are not expected to recognize a gain (or loss) for U.S. federal income tax purposes as a result of the Reorganization (except with respect to cash received, as explained elsewhere in this Supplement).

In connection with the Reorganization, shareholders of the Fund will receive ETF shares of the Acquiring Fund equal in value to the number of shares of the Fund they own, including a cash payment in lieu of fractional shares of the Acquiring Fund, which cash payment may be taxable.

Completion of the Reorganization is subject to a number of conditions under the Plan, but shareholders of the Fund are not required to approve the Reorganization. Existing shareholders of the Fund will receive a combined prospectus/information statement describing in detail both the Reorganization and the Acquiring Fund and summarizing the Board's considerations in approving the Reorganization.

------

Although shareholder approval of the Reorganization is not required and BlackRock does not anticipate that the Reorganization will be terminated, if the Reorganization is terminated, shareholders of the Fund would be notified of the change.

The following changes will take effect either immediately or on an upcoming future date as described below. These actions include limits on new purchases of certain Fund shares, the removal of sales charges on purchases of Fund shares, the removal of contingent deferred sales charges on redemptions of Fund shares, and the waiver of Distribution and Service (Rule 12b-1) Fees on Fund shares.

#### IMPORTANT NOTICE ABOUT YOUR FUND ACCOUNT

#### QUESTIONS AND ANSWERS
The following is a brief Q&A that provides information to help you to determine if you need to take action with respect to your Fund shareholder account prior to the Reorganization in order to receive shares of the Acquiring Fund.

Q. What types of shareholder accounts can receive shares of the Acquiring Fund as part of the Reorganization?

**A.** If you hold your shares of the Fund in a brokerage account that permits you to purchase securities traded in the stock market, such as ETFs or other types of stocks, then you will be eligible to receive shares of the Acquiring Fund in the Reorganization. No further action is required.

Q. What types of shareholder accounts cannot receive shares of the Acquiring Fund as part of the Reorganization?

**A.** The following account types cannot hold shares of ETFs:

*Non-Accommodating Brokerage Accounts*. If you hold your shares of the Fund in a brokerage account with a financial intermediary that only allows you to hold shares of mutual funds in the account, you will need to contact your financial intermediary to set up a brokerage account that permits investments in ETF shares.

*Non-Accommodating Retirement Accounts*. If you hold your shares of the Fund through an individual retirement account ("IRA") or group retirement plan whose plan sponsor does not have the ability to hold shares of ETFs on its platform, you may need to redeem your shares prior to the Reorganization or, if applicable, your financial intermediary may transfer your investment in the Fund to a different investment option prior to the Reorganization.

*Direct Accounts*. **If you hold your shares of the Fund in an account directly with the Fund at its transfer agent, BNY Mellon Investment Servicing (US) Inc. (a "direct account"), you must transfer your shares of**

------

**the Fund to a brokerage account that can accept shares of the Acquiring Fund prior to November 6, 2026 in order to receive shares of the Acquiring Fund.** For this purpose, a direct account includes a direct IRA. If you hold your shares of the Fund through a direct IRA and do not take action prior to November 6, 2026, your Fund shares will be exchanged on November 6, 2026 for shares of BlackRock Summit Cash Reserves Fund (the "Money Market Fund"), a series of BlackRock Financial Institutions Series Trust equal in value to the NAV of your Fund shares. Such shareholders holding Investor A Shares or Class R Shares of the Fund will be exchanged into Investor A Shares of the Money Market Fund, such shareholders holding Investor C Shares of the Fund will be exchanged into Investor C Shares of the Money Market Fund, and such shareholders holding Institutional Shares or Class K Shares of the Fund will be exchanged into Institutional Shares of the Money Market Fund. You have a direct account if you receive quarterly account statements directly from the Fund and not from a third-party broker-dealer.

**The redemption of Fund shares or the transfer of Fund shares to a different investment option prior to the Reorganization, or the receipt of cash or shares in a fund other than the Acquiring Fund in exchange for Fund shares, is expected to be a taxable transaction to shareholders in non-tax qualified accounts. If you are unsure about the ability of your account to accept shares of the Acquiring Fund, please call (800) 441-7762 or contact your financial advisor or other financial intermediary.**

Q. How do I transfer my Fund shares from a direct account to a brokerage account that will accept Acquiring Fund shares?

**A.** Transferring your shares from a direct account to a brokerage account that can accept shares of the Acquiring Fund should be a simple process. If you have a brokerage account or a relationship with a brokerage firm, please talk to your broker and inform the broker that you would like to transfer a mutual fund position that you hold directly with the Fund into your brokerage account. **Also inform your broker that such an account will need to be set up to accept shares of an ETF,** such as the Acquiring Fund. If you do not have a brokerage account or a relationship with a brokerage firm, you will need to open an account.

We suggest you provide your broker with a copy of your quarterly statement from the Fund. Your broker will require your account number with the Fund, which can be found on your statement. Your broker will help you complete a form to initiate the transfer. Once you sign that form, your broker will submit the form to the transfer agent directly, and the shares will be transferred into your brokerage account. **The sooner you initiate the transfer, the better.**

Q. How do I transfer my Fund shares from a non-accommodating brokerage account to a brokerage account that will accept Acquiring Fund shares?

**A.** The broker where you hold your Fund shares should be able to assist you in changing the characteristics of your brokerage account to an account that is permitted to invest in ETF shares. **Contact your broker right away to make the necessary changes to your account.**

Q. What will happen if I do not have a brokerage account that can accept Acquiring Fund shares at the time of the Reorganization?

**A.** In order to receive shares of the Acquiring Fund as part of the Reorganization, you must hold your shares of the Fund through a brokerage account that can accept shares of an ETF (the Acquiring Fund) on the closing date of the Reorganization as follows:

• *Non-Accommodating Brokerage Accounts*. If you hold your shares of the Fund in a brokerage account with a financial intermediary that only allows you to hold shares of mutual funds in the account, you will need to contact your financial intermediary to set up a brokerage account that permits investments in ETF shares. If such a change is not made before the Reorganization, you will not receive shares of the Acquiring Fund as part of the Reorganization. Instead, your investment will be liquidated on November 19, 2026, and you will receive cash equal in value to the NAV of your Fund shares.

------

• *Non* - *Accommodating Retirement Accounts*. If you hold your shares of the Fund through an IRA or group retirement plan whose plan sponsor does not have the ability to hold shares of ETFs on its platform, you may need to redeem your shares prior to the Reorganization or, if applicable, your financial intermediary may transfer your investment in the Fund to a different investment option prior to the Reorganization. If either such change is not made before the Reorganization, you will not receive shares of the Acquiring Fund as part of the Reorganization. Instead, your investment will be liquidated on November 19, 2026, and you will receive cash equal in value to the NAV of your Fund shares.

• *Direct Accounts.* If you hold your shares of the Fund in a direct account, you should transfer your shares of the Fund to a brokerage account that can accept shares of the Acquiring Fund prior to the Reorganization. If such a change is not made before November 6, 2026, you will not receive shares of the Acquiring Fund as part of the Reorganization. Instead, your investment will be liquidated on November 6, 2026, and you will receive cash equal in value to the NAV of your Fund shares.

• *Direct IRA.* If you hold your shares of the Fund through a direct IRA and you do not take action to transfer your investment in the Fund to a different investment option prior to November 6, 2026, your Fund shares will be exchanged on November 6, 2026 for shares of BlackRock Summit Cash Reserves Fund (the "Money Market Fund"), a series of BlackRock Financial Institutions Series Trust equal in value to the NAV of your Fund shares. Such shareholders holding Investor A Shares or Class R Shares of the Fund will be exchanged into Investor A Shares of the Money Market Fund, such shareholders holding Investor C Shares of the Fund will be exchanged into Investor C Shares of the Money Market Fund, and such shareholders holding Institutional Shares or Class K Shares of the Fund will be exchanged into Institutional Shares of the Money Market Fund.

**In some cases, the liquidation of your investment and return of cash, or the transfer of your investment to a different investment option, may be subject to fees and expenses and it may take time to receive your cash. Additionally, the redemption of Fund shares or the transfer of Fund shares to a different investment option prior to the Reorganization, or the receipt of cash or shares in a fund other than the Acquiring Fund in exchange for Fund shares, is expected to be a taxable transaction to shareholders in non-tax qualified accounts.** Please consult with your financial intermediary for more information on the impact that the Reorganization will have on you and your investments.

Q. What if I do not want to own shares of the Acquiring Fund?

A. If you do not want to receive shares of the Acquiring Fund in connection with the Reorganization, you can exchange your Fund shares for shares of another mutual fund advised by BlackRock Advisors, LLC ("BAL") or its affiliates or redeem your Fund shares. Prior to doing so, however, you should consider the tax consequences associated with either action. **Each of the exchange of your Fund shares for shares of another mutual fund advised by BAL or its affiliates or the redemption of your Fund shares will be a taxable transaction to shareholders in non-tax qualified accounts.** The last date to exchange your shares into another mutual fund advised by BAL or its affiliates prior to the Reorganization is November 19, 2026 (November 5, 2026, for existing direct accounts and direct IRAs). The last date to redeem your shares prior to the Reorganization is November 19, 2026. These dates may change if the closing date of the Reorganization changes. Any changes to the closing date of the Reorganization will be communicated to shareholders.

\* \* \*
