Dear Preferred Shareholder:

IMPORTANT NOTICE

TO PREFERRED SHAREHOLDERS OF

QUESTIONS & ANSWERS

Although we urge you to read the entire Proxy Statement, we have provided for your convenience a brief overview of some of the important questions concerning the joint special shareholder meeting (the “Special Meeting”) of BlackRock Investment Quality Municipal Trust, Inc. (“BKN”), BlackRock MuniYield Fund, Inc. (“MYD”), BlackRock MuniYield Quality Fund II, Inc.

(“MQY” or the “Acquiring Fund” and collectively with BKN, MYD, MQT, BHV and MPA, the “Funds,” and each, a “Fund”) and the proposals to be voted on. It is expected that the effective dates (collectively, the “Closing Date”) of the Reorganizations will be sometime during the fourth quarter of 2025, but they may be at a different time as described in the Proxy Statement.

The enclosed Proxy Statement is being sent only to (i) the holders of Variable Rate Demand Preferred Shares (“VRDP Shares” and the holders thereof, “VRDP Holders,”) of the Acquiring Fund, MYD, BHV and MPA and (ii) the holders of Variable Muni Term Preferred Shares (“VMTP Shares” and the holders thereof, “VMTP Holders”) of BKN and MQT.

You are also being asked to vote as a separate class on a proposal to approve the MPA Reorganization Agreement and the MPA Reorganization.

Preferred Shareholders of BlackRock MuniYield Quality Fund, Inc. (NYSE Ticker: MQY): You and the common shareholders of the Acquiring Fund are being asked to vote as a single class on a proposal to approve the issuance of additional common shares of the Acquiring Fund in connection with each Reorganization Agreement (each, an “Issuance” and collectively, the “Issuances”).

You are also being asked to vote as a separate class on a proposal to approve each Reorganization Agreement and the transactions contemplated therein, including amendments to the Articles Supplementary of Variable Rate Demand Preferred Shares of the Acquiring Fund (“MQY Articles Supplementary”) in connection with the issuance of additional Acquiring Fund VRDP Shares.

The term “Combined Fund” refers to the Acquiring Fund as the surviving Fund after the consummation of each of the Reorganizations.

Each Reorganization is not contingent upon the approval of any other Reorganization. If a Reorganization is not consummated, the Fund for which such Reorganization(s) was not consummated would continue to exist and operate on a standalone basis.

Q:Why has each Fund’s Board recommended these proposals?
A:The Board of Directors or the Board of Trustees, as applicable (each, a “Board” and each member thereof, a “Board Member”), of each Fund has determined that its Reorganization(s) is in the best interests of its Fund and that the interests of existing common shareholders and preferred shareholders of its Fund will not be diluted with respect to net asset value (“NAV”) and liquidation preference, respectively, as a result of the Reorganization. The Reorganizations seek to achieve certain economies of scale and other operational efficiencies by combining six funds that have similar investment objectives, investment strategies, policies and restrictions, and are managed by the same investment adviser, BlackRock Advisors, LLC (the “Investment Advisor”).

iii

In light of these similarities, the Reorganizations are intended to reduce fund redundancies and create a single, larger fund that may benefit from anticipated operating efficiencies and economies of scale. The Reorganizations are intended to result in the following potential benefits to common shareholders:

(i)lower net total expenses (excluding leverage expenses and Target Funds extraordinary expenses) per Common Share for common shareholders of each Fund (as common shareholders of the Combined Fund following the Reorganizations) due to economies of scale resulting from the larger size of the Combined Fund;
(ii)improved net earnings yield on NAV for common shareholders of BHV, MPA and the Acquiring Fund;
(iii)improved secondary market trading of the common shares of the Combined Fund; and
(iv)operating and administrative efficiencies for the Combined Fund, including the potential for the following:
(a)greater investment flexibility and investment options;
(b)greater diversification of portfolio investments;
(c)the ability to trade portfolio securities in larger positions and more favorable transaction terms;
(d)additional sources of leverage or more competitive leverage terms and more favorable transaction terms;
(e)benefits from having fewer closed-end funds offering similar products in the market, including an increased focus by investors on the remaining funds in the market (including the Combined Fund) and additional research coverage; and
(f)benefits from having fewer similar funds in the same fund complex, including a simplified operational model and a reduction in risk of operational, legal and financial errors.

The Board of each Fund, including Board Members thereof who are not “interested persons” (as defined in the 1940 Act), approved its Reorganization(s), its Reorganization Agreement(s) and the Issuances, as applicable, concluding that the Reorganization(s) is in the best interests of its Fund and that the interests of existing common shareholders and preferred shareholders of its Fund will not be diluted with respect to NAV and liquidation preference, respectively, as a result of the Reorganization(s). As a result of the Reorganizations, however, common and preferred shareholders of each Fund may hold a reduced percentage of ownership in the larger Combined Fund than they did in any of the individual Funds before the Reorganizations. Each Board’s conclusion was based on each Board Member’s business judgment after consideration of all relevant factors taken as a whole with respect to its Fund and the Fund’s common and preferred shareholders, although individual Board Members may have placed different weight on various factors and assigned different degrees of materiality to various factors.

Because the shareholders of each Fund will vote separately on the Fund’s respective Reorganization(s) or Issuances, as applicable, there are multiple potential combinations of Reorganizations. To the extent any Reorganization is not completed, any expected expense savings by the Combined Fund, or other potential benefits resulting from the Reorganizations, may be reduced.

If a Reorganization is not consummated, then the Investment Advisor may, in connection with ongoing management of the Fund for which such Reorganization(s) was not consummated and its product line, recommend alternative proposals to the Board of that Fund.

iv

Q:How will holders of preferred shares be affected by the Reorganizations?
A:As of the date of the enclosed Proxy Statement, the Acquiring Fund, MYD, BHV and MPA each has VRDP Shares outstanding and BKN and MQT each has VMTP Shares outstanding. As of July 31, 2025, BKN had 678 Series W-7 VMTP Shares outstanding, MYD had 2,514 Series W-7 VRDP Shares outstanding, MQT had 786 Series W-7 VMTP Shares outstanding, BHV had 116 Series W-7 VRDP Shares outstanding, MPA had 826 Series W-7 VRDP Shares outstanding and the Acquiring Fund had 2,251 Series W-7 VRDP Shares outstanding and 2,252 Series W-7A VRDP Shares outstanding.

In connection with the Reorganizations, the Acquiring Fund expects to issue 678 additional VRDP Shares to BKN VMTP Holders, 2,514 additional VRDP Shares to MYD VRDP Holders, 786 additional VRDP Shares to MQT VMTP Holders, 116 additional VRDP Shares to BHV VRDP Holders and 826 additional VRDP Shares to MPA VRDP Holders. Following the completion of the Reorganizations, the Combined Fund is expected to have 9,423 VRDP Shares outstanding.

The Board of each Fund has authorized the redemption of up to 67% of the Fund’s currently outstanding VRDP Shares or VMTP Shares, as applicable, on one or more occasions between April 1, 2025 and October 1, 2025. Any such redemption is not related to the Reorganizations or contingent on shareholder approval of the Reorganizations. The timing and amount of any redemption of a Fund’s currently outstanding VRDP Shares or VMTP Shares, as applicable, would depend on a number of factors, including, among others, the desired mix of leverage from preferred shares versus residual interest municipal tender option bonds (“TOBs”), yield levels and borrowing costs.

Assuming all of the Reorganizations are approved by shareholders, upon the Closing Date of the Reorganizations, BKN, MYD, MQT, BHV and MPA VMTP Holders or VRDP Holders, as applicable, will receive on a one-for-one basis one newly issued Acquiring Fund VRDP Share, par value $0.10 per share and with a liquidation preference of $100,000 per share (plus any accumulated and unpaid dividends that have accrued on the BKN, MYD, MQT, BHV or MPA VMTP Shares or VRDP Shares, as applicable, up to and including the day immediately preceding the Closing Date if such dividends have not been paid prior to the Closing Date), in exchange for each BKN, MYD, MQT, BHV and MPA VMTP Share or VRDP Share held by the BKN, MYD, MQT, BHV and MPA VMTP Holders or VRDP Holders, as applicable, immediately prior to the Closing Date. The newly issued Acquiring Fund VRDP Shares are expected to be of an identical or a substantially identical series as those of the Acquiring Fund’s outstanding VRDP Shares. No fractional Acquiring Fund VRDP Shares will be issued. The terms of the Acquiring Fund VRDP Shares to be issued in connection with the Reorganizations will be identical or substantially identical to the terms of the Acquiring Fund’s outstanding VRDP Shares and will rank on parity with the Acquiring Fund’s outstanding VRDP Shares as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund. The Reorganizations will not result in any changes to the terms of the Acquiring Fund’s VRDP Shares currently outstanding.

The newly issued Acquiring Fund VRDP Shares will have terms that are substantially similar to the terms of the outstanding MYD, BHV and MPA VRDP Shares, except that the dividend rate of the newly issued Acquiring Fund VRDP Shares may differ. In addition, the MYD, BHV and MPA VRDP Shares have a mandatory redemption date of July 1, 2041, July 1, 2042 and June 1, 2041, respectively, while the newly issued Acquiring Fund VRDP Shares are expected to have a mandatory redemption date of 30 years from the date of issuance.

v

The dividend rate of the BKN and MQT VMTP Shares is based on a variable rate set weekly at a fixed rate spread to the Securities Industry and Financial Markets Association Municipal Swap Index. The term redemption date of the BKN and MQT VMTP Shares is July 2, 2026.

The Acquiring Fund may designate any succeeding subsequent rate period of the VRDP Shares as a “special rate period” subject to the restrictions and requirements set forth in the governing instrument for its VRDP Shares. During a special rate period, the Acquiring Fund may choose to modify the terms of the VRDP Shares as permitted by the governing instrument for its VRDP Shares, including, for example, special provisions relating to the calculation of dividends and the redemption of the VRDP Shares. See “Information about the Preferred Shares of the Funds” in the Proxy Statement for additional information about the preferred shares of each Fund.

None of the expenses of the Reorganizations are expected to be borne by the VMTP Holders or the VRDP Holders, as applicable, of the Funds.

Following the Reorganizations, the VRDP Holders or VMTP Holders of each Fund, as applicable, will be VRDP Holders of the larger Combined Fund that will have a larger asset base and more preferred shares outstanding than any Fund individually before the Reorganizations. With respect to matters requiring all preferred shareholders to vote separately or common and preferred shareholders to vote together as a single class, following the Reorganizations, VRDP Holders of the Combined Fund may hold a smaller percentage of the outstanding preferred shares of the Combined Fund as compared to their percentage holdings of outstanding preferred shares of their respective Fund prior to the Reorganizations.

Q:How similar are the Funds?
A:The Funds have the same investment adviser, officers and directors/trustees. BKN, MYD, MQT and the Acquiring Fund are each incorporated as a Maryland corporation, BHV is formed as a Delaware statutory trust, and MPA is formed as a Massachusetts business trust.

Each of the Acquiring Fund, BKN, MYD, MQT, BHV and MPA has its common shares listed on the NYSE. The Acquiring Fund, MYD, BHV and MPA each has privately placed VRDP Shares outstanding. BKN and MQT each has privately placed VMTP Shares outstanding. Each of the Acquiring Fund, BKN, MYD, MQT, BHV and MPA are managed by a team of investment professionals led by Michael Kalinoski, CFA, Director at BlackRock, Walter O’Connor, CFA, Managing Director at BlackRock, Christian Romaglino, CFA, Director at BlackRock, Kevin Maloney, CFA, Director at BlackRock, Phillip Soccio, CFA, Director at BlackRock and Kristi Manidis, Director at BlackRock. Following the Reorganizations, it is expected that the Combined Fund will be managed by the same team of investment professionals.

The investment objective, principal investment strategies and operating policies, and investment restrictions of the Combined Fund will be those of the Acquiring Fund, which are similar to those of BKN, MYD, MQT, BHV and MPA, although there are some differences as set out below.

(“Moody’s”), S&P Global Ratings (“S&P”) or Fitch Ratings (“Fitch”)) or are unrated but judged to be of comparable quality by the Investment Advisor. Below investment grade quality means securities rated at the time of purchase Ba or below by Moody’s, BB or below by S&P or Fitch, or securities determined by the Investment Advisor to be of comparable quality. Below investment grade quality is regarded as predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal. Such securities commonly are referred to as “high yield” or “junk” bonds.

Under normal market conditions, BKN will invest at least 80% of its Managed Assets in investment quality securities. An investment quality security is a security that is rated BBB or Baa or higher by Moody’s, S&P, Fitch or another nationally recognized rating agency or, if unrated, deemed to be of comparable quality by the Investment Advisor. BKN may invest up to 20% of its Managed Assets, measured at the time of investment, in securities rated BB/Ba or B by Moody’s, S&P, Fitch or another nationally recognized rating agency or, if unrated, deemed to be of comparable credit quality by the Investment Advisor. “Managed Assets” are BKN’s net assets plus the amount of borrowings for investment purposes.Under normal market conditions, MYD expects to invest at least 75% of its total assets in a portfolio of long-term Municipal Bonds that are commonly referred to as “investment grade” securities, which are obligations rated at the time of purchase within the four highest-quality ratings as determined by either Moody’s, S&P or Fitch. In the case of short-term notes, the investment grade rating categories are SP-1+ through SP-2 for S&P, MIG-1 through MIG-3 for Moody’s and F-1+ through F-3 for Fitch. In the case of tax-exempt commercial paper, the investment grade rating categories are A-1+ through A-3 for S&P, Prime-1 through Prime-3 for Moody’s and F-1+ through F-3 for Fitch.

Leverage: Each Fund utilizes leverage through the issuance of either VMTP Shares or VRDP Shares and residual interest municipal tender option bonds (“TOBs”). See “The Acquiring Fund’s Investments—Leverage;” “Risk Factors and Special Considerations—General Risks of Investing in the Acquiring Fund—Leverage Risk;” and “Risk Factors and Special Considerations—General Risks of Investing in the Acquiring Fund—Tender Option Bond Risk.” Each of BKN and MQT currently leverages its assets through the use of VMTP Shares and TOBs. Each of the Acquiring Fund, MYD, BHV and MPA currently leverages its assets through the use of VRDP Shares and TOBs. The Acquiring Fund is expected to continue to leverage its assets through the use of VRDP Shares and TOBs after the Closing Date of the Reorganizations. As noted above, the Board of the Acquiring Fund has authorized the redemption of up to 67% of the Fund’s currently outstanding VRDP Shares on one or more occasions between April 1, 2025 and October 1, 2025, which redemption is not subject to shareholder approval of any of the Reorganizations. Please see “Information about the Preferred Shares of the Funds” in the Proxy Statement for additional information about the preferred shares of each Fund.

The annualized dividend rates for the preferred shares for each Fund’s twelve-month period ended January 31, 2025 were as follows:

FundPreferred SharesRate
BKNVMTP Shares4.69%
MYDVRDP Shares4.03%
MQTVMTP Shares4.69%
BHVVRDP Shares4.22%
MPAVRDP Shares4.22%
Acquiring Fund (MQY)VRDP Shares3.67%

Please see below a comparison of certain important ratios related to (i) each Fund’s use of leverage as of July 31, 2025, (ii) the Combined Fund’s estimated use of leverage, assuming only the Reorganization of BHV into the Acquiring Fund had taken place as of July 31, 2025, and (iii) the Combined Fund’s estimated use of leverage, assuming the Reorganizations of all the Funds had taken place as of July 31, 2025.

(2)Effective leverage is a Fund’s effective economic leverage and includes both regulatory leverage and the leverage effects of certain derivative investments in the Fund’s portfolio. Currently, the leverage effects of TOB inverse floater holdings, in addition to any regulatory leverage, are included in effective leverage ratios.
Q:How will the Reorganizations be effected?
A:Assuming a Reorganization receives the requisite shareholder approvals, as well as certain consents, confirmations and/or waivers from various third parties, including the liquidity

xi

providers with respect to the outstanding MYD, BHV, MPA and Acquiring Fund VRDP Shares, the Acquiring Fund will acquire substantially all of a Target Fund’s assets and assume substantially all of such Target Fund’s liabilities in exchange solely for newly issued common shares and VRDP Shares of the Acquiring Fund, which will be distributed to the shareholders of the Target Fund (although cash will be distributed in lieu of fractional common shares). A Target Fund will then terminate its registration under the 1940 Act and liquidate, dissolve and terminate in accordance with its respective charter/declaration of trust and applicable state law.

Shareholders of BKN, MYD, MQT, BHV and MPA will become shareholders of the Acquiring Fund. Common shareholders of BKN, MYD, MQT, BHV and MPA will receive newly issued common shares of the Acquiring Fund, par value $0.10 per share, the aggregate NAV (not the market value) of which will equal the aggregate NAV (not the market value) of the common shares of BKN, MYD, MQT, BHV and MPA such shareholders held immediately prior to the Closing Date (although common shareholders of BKN, MYD, MQT, BHV and MPA may receive cash for fractional common shares). The aggregate NAV of each Fund immediately prior to the applicable Reorganization will reflect accrued expenses associated with such Reorganization. The NAV of BKN, MYD, MQT, BHV and MPA common shares will not be diluted as a result of the Reorganizations. The common shareholders of each Fund have substantially similar voting rights and rights with respect to the payment of dividends and distribution of assets upon liquidation of their respective Fund and have no preemptive, conversion or exchange rights.

On the Closing Date of the Reorganizations, BKN, MYD, MQT, BHV and MPA VMTP Holders or VRDP Holders, as applicable, will receive on a one-for-one basis one newly issued Acquiring Fund VRDP Share, par value $0.10 per share and with a liquidation preference of $100,000 per share (plus any accumulated and unpaid dividends that have accrued on the BKN, MYD, MQT, BHV or MPA VMTP Shares or VRDP Shares, as applicable, up to and including the day immediately preceding the Closing Date of the Reorganizations if such dividends have not been paid prior to the Closing Date), in exchange for each BKN, MYD, MQT, BHV or MPA VRDP Share or VMTP Share held by the BKN, MYD, MQT, BHV or MPA VMTP Holders or VRDP Holders, as applicable, immediately prior to the Closing Date. The newly issued Acquiring Fund VRDP Shares are expected to be of an identical or a substantially identical series as those of the Acquiring Fund’s outstanding VRDP Shares. No fractional Acquiring Fund VRDP Shares will be issued. The terms of the Acquiring Fund VRDP Shares to be issued in connection with the Reorganizations will be identical or substantially identical to the terms of the Acquiring Fund’s outstanding VRDP Shares and will rank on parity with the Acquiring Fund’s outstanding VRDP Shares as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund. The Reorganizations will not result in any changes to the terms of the Acquiring Fund’s VRDP Shares currently outstanding.

The newly issued Acquiring Fund VRDP Shares will have terms that are substantially similar to the terms of the outstanding MYD, BHV and MPA VRDP Shares, except that the dividend rate of the newly issued Acquiring Fund VRDP Shares may differ. In addition, the MYD, BHV and MPA VRDP Shares have a mandatory redemption date of July 1, 2041, July 1, 2042 and June 1, 2041, respectively, while the newly issued Acquiring Fund VRDP Shares are expected to have a mandatory redemption date of 30 years from the date of issuance.

The dividend rate of the BKN and MQT VMTP Shares is based on a variable rate set weekly at a fixed rate spread to the Securities Industry and Financial Markets Association Municipal Swap Index. The term redemption date of the BKN and MQT VMTP Shares is July 2, 2026.

xii

The Acquiring Fund may designate any succeeding subsequent rate period of the VRDP Shares as a “special rate period” subject to the restrictions and requirements set forth in the governing instrument for its VRDP Shares. During a special rate period, the Acquiring Fund may choose to modify the terms of the VRDP Shares as permitted by the governing instrument for its VRDP Shares, including, for example, special provisions relating to the calculation of dividends and the redemption of the VRDP Shares. See “Information about the Preferred Shares of the Funds” in the Proxy Statement for additional information about the preferred shares of each Fund.

Shareholders of the Acquiring Fund will remain shareholders of the Acquiring Fund, which will have additional common shares and VRDP Shares outstanding after the Reorganizations.

Q:Will I have to pay any U.S. federal income taxes as a result of the Reorganizations?
A:Each Reorganization is intended to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. If a Reorganization so qualifies, in general, shareholders of BKN, MYD, MQT, BHV and MPA will recognize no gain or loss for U.S. federal income tax purposes upon the exchange of their common shares for Acquiring Fund Shares pursuant to their Reorganization (except with respect to cash received in lieu of fractional common shares). Additionally, each of BKN, MYD, MQT, BHV and MPA will recognize no gain or loss for U.S. federal income tax purposes by reason of its Reorganization. Neither the Acquiring Fund nor its shareholders will recognize any gain or loss for U.S. federal income tax purposes pursuant to the Reorganizations.

As discussed above, shareholders of each Fund may receive distributions prior to, or after, the consummation of the Reorganizations, including distributions attributable to their proportionate share of each Fund’s undistributed net investment income declared prior to the consummation of the Reorganizations or the Combined Fund built-in gains, if any, recognized after the Reorganizations, when such income and gains are eventually distributed by the Combined Fund. To the extent that such a distribution is not an “exempt interest dividend” (as defined in the Code), the distribution may be taxable to shareholders for U.S. federal income tax purposes.

The Funds’ shareholders should consult their own tax advisers regarding the U.S. federal income tax consequences of the Reorganizations, as well as the effects of state, local and non-U.S. tax laws, including possible changes in tax laws.

Q:What is the impact on shareholders of BHV and MPA, which invest principally in securities that are exempt from Virginia and Pennsylvania state taxes, respectively?
A:Shareholders of BHV and MPA will lose the benefit of a Virginia and Pennsylvania state tax exemption, respectively, as a result of the Reorganizations, except to the extent that the Acquiring Fund invests in securities that pay interest that is exempt from Virginia or Pennsylvania state income taxes.

However, BHV and MPA shareholders would remain invested in a fund that seeks to obtain income that is exempt from federal income taxes and that has greater flexibility to invest in a broader range of issuers than a fund that focuses its investments in a single state.

xiii

Q:Will I have to pay any sales load, commission or other similar fees in connection with the Reorganizations?
A:You will pay no sales loads or commissions in connection with the Reorganizations. Regardless of whether the Reorganizations are completed, however, the costs associated with the Reorganizations, including the costs associated with the Special Meeting, will be borne directly by each of the respective Funds incurring the expense as discussed more fully in the Proxy Statement.

Common shareholders of each Fund will indirectly bear all or a portion of the costs of the Reorganizations. The expenses of the Reorganizations of BKN, MYD, MQT, BHV, MPA and the Acquiring Fund are estimated to be approximately $323,000, $477,000, $331,000, $187,000, $270,000 and $592,000, respectively, of which the Investment Advisor will bear approximately $0, $146,000, $0, $0, $0 and $0, respectively. The actual costs associated with the Reorganizations may be more or less than the estimated costs discussed herein.

VMTP Holders and VRDP Holders, as applicable, are not expected to bear any costs of the Reorganizations.

Neither the Funds nor the Investment Advisor will pay any direct expenses of shareholders arising out of or in connection with the Reorganizations (e.g., expenses incurred by the shareholder as a result of attending the Special Meeting, voting on the Reorganizations or other action taken by the shareholder in connection with the Reorganizations).

Q:What shareholder approvals are required to complete the Reorganizations?
A:The BKN Reorganization is contingent upon the following approvals:
1.The approval of the BKN Reorganization Agreement and the transactions contemplated therein, including the termination of BKN’s registration under the 1940 Act and the dissolution of BKN under Maryland law, by BKN’s common shareholders and VMTP Holders voting as a single class;
2.The approval of the BKN Reorganization Agreement and the transactions contemplated therein, including the termination of BKN’s registration under the 1940 Act and the dissolution of BKN under Maryland law, by BKN’s VMTP Holders voting as a separate class;
3.The approval of the BKN Reorganization Agreement and the transactions contemplated therein, including amendments to the MQY Articles Supplementary in connection with the issuance of additional Acquiring Fund VRDP Shares, by Acquiring Fund VRDP Holders voting as a separate class; and
4.The approval of the Issuance with respect to the BKN Reorganization by the Acquiring Fund’s common shareholders and Acquiring Fund VRDP Holders voting as a single class.

The MYD Reorganization is contingent upon the following approvals:

1.The approval of the MYD Reorganization Agreement and the transactions contemplated therein, including the termination of MYD’s registration under the 1940 Act and the dissolution of MYD under Maryland law, by MYD’s common shareholders and VRDP Holders voting as a single class;

xiv

2.The approval of the MYD Reorganization Agreement and the transactions contemplated therein, including the termination of MYD’s registration under the 1940 Act and the dissolution of MYD under Maryland law, by MYD’s VRDP Holders voting as a separate class;
3.The approval of the MYD Reorganization Agreement and the transactions contemplated therein, including amendments to the MQY Articles Supplementary in connection with the issuance of additional Acquiring Fund VRDP Shares, by Acquiring Fund VRDP Holders voting as a separate class; and
4.The approval of the Issuance with respect to the MYD Reorganization by the Acquiring Fund’s common shareholders and Acquiring Fund VRDP Holders voting as a single class.

The MQT Reorganization is contingent upon the following approvals:

1.The approval of the MQT Reorganization Agreement and the transactions contemplated therein, including the termination of MQT’s registration under the 1940 Act and the dissolution of MQT under Maryland law, by MQT’s common shareholders and VMTP Holders voting as a single class;
2.The approval of the MQT Reorganization Agreement and the transactions contemplated therein, including the termination of MQT’s registration under the 1940 Act and the dissolution of MQT under Maryland law, by MQT’s VMTP Holders voting as a separate class;
3.The approval of the MQT Reorganization Agreement and the transactions contemplated therein, including amendments to the MQY Articles Supplementary in connection with the issuance of additional Acquiring Fund VRDP Shares, by Acquiring Fund VRDP Holders voting as a separate class; and
4.The approval of the Issuance with respect to the MQT Reorganization by the Acquiring Fund’s common shareholders and Acquiring Fund VRDP Holders voting as a single class.

The BHV Reorganization is contingent upon the following approvals:

1.The approval of the BHV Reorganization Agreement and the transactions contemplated therein, including the termination of BHV’s registration under the 1940 Act and the dissolution of BHV under Delaware law, by BHV’s common shareholders and VRDP Holders voting as a single class;
2.The approval of the BHV Reorganization Agreement and the transactions contemplated therein, including the termination of BHV’s registration under the 1940 Act and the dissolution of BHV under Delaware law, by BHV’s VRDP Holders voting as a separate class;
3.The approval of the BHV Reorganization Agreement and the transactions contemplated therein, including amendments to the MQY Articles Supplementary in connection with the issuance of additional Acquiring Fund VRDP Shares, by Acquiring Fund VRDP Holders voting as a separate class; and
4.The approval of the Issuance with respect to the BHV Reorganization by the Acquiring Fund’s common shareholders and Acquiring Fund VRDP Holders voting as a single class.

xv

The MPA Reorganization is contingent upon the following approvals:

1.The approval of the MPA Reorganization Agreement and the transactions contemplated therein, including the termination of MPA’s registration under the 1940 Act and the dissolution of MPA under Massachusetts law, by MPA’s common shareholders and VRDP Holders voting as a single class;
2.The approval of the MPA Reorganization Agreement and the transactions contemplated therein, including the termination of MPA’s registration under the 1940 Act and the dissolution of MPA under Massachusetts law, by MPA’s VRDP Holders voting as a separate class;
3.The approval of the MPA Reorganization Agreement and the transactions contemplated therein, including amendments to the MQY Articles Supplementary in connection with the issuance of additional Acquiring Fund VRDP Shares, by Acquiring Fund VRDP Holders voting as a separate class; and
4.The approval of the Issuance with respect to the MPA Reorganization by the Acquiring Fund’s common shareholders and Acquiring Fund VRDP Holders voting as a single class.

Each Reorganization is not contingent upon the approval of any other Reorganization. If a Reorganization is not consummated, the Fund for which such Reorganization(s) was not consummated would continue to exist and operate on a standalone basis.

If the requisite shareholder approvals for a Reorganization are not obtained or a Reorganization is not otherwise consummated, the Board of the Fund(s) for which such Reorganization(s) were not consummated may take such actions as it deems in the best interests of the Fund, including conducting additional solicitations with respect to the Reorganization(s) or continuing to operate the Fund as a standalone Maryland corporation, Delaware statutory trust or Massachusetts business trust, as applicable, registered under the 1940 Act as aclosed-end management investment company advised by the Investment Advisor. The Investment Advisor may, in connection with the ongoing management of the Fund and its product line, recommend alternative proposals to the Board of the Fund.

In order for the Reorganizations to occur, each Fund must obtain all requisite shareholder approvals with respect to its Reorganization(s), as well as certain consents, confirmations and/or waivers from various third parties, including the liquidity providers with respect to the outstanding Acquiring Fund, MYD, BHV and MPA VRDP Shares. Because the closing of each Reorganization is contingent upon the applicable Fund and the Acquiring Fund obtaining the requisite shareholder approvals and third-party consents and satisfying (or obtaining the waiver of) other closing conditions, it is possible that a Reorganization will not occur, or that only one of BKN, MYD, MQT, BHV or MPA will be reorganized into the Acquiring Fund, even if shareholders of a Fund entitled to vote on the Reorganization approve the Reorganization and such Fund satisfies all of its closing conditions, if the other Fund does not obtain its requisite shareholder approvals or satisfy its closing conditions.

The preferred shares were issued on a private placement basis to one or a small number of institutional holders. Please see “Information about the Preferred Shares of the Funds” in the Proxy Statement for additional information. To the extent that one or more preferred shareholder of BKN, MYD, MQT, BHV, MPA or the Acquiring Fund owns, holds or controls, individually or in the aggregate, all or a significant portion of such Fund’s outstanding preferred shares, the preferred shareholder approval required for a Reorganization may turn on the exercise of voting rights by

xvi such particular preferred shareholder(s) and its (or their) determination as to the favorability of the Reorganization with respect to its (or their) interests. The Funds exercise no influence or control over the determinations of such preferred shareholder(s) with respect to the Reorganizations; there is no guarantee that such preferred shareholder(s) will approve the Reorganizations, over which it (or they) may exercise effective disposition power.

Q:Why is the vote of shareholders of the Acquiring Fund being solicited in connection with the Reorganizations?
A:The rules of the New York Stock Exchange (on which the Acquiring Fund common shares are listed) require the Acquiring Fund’s shareholders to approve each Issuance with respect to a Reorganization. If the Issuance with respect to a Reorganization is not approved, then the corresponding Reorganization will not occur.

We are also seeking the approval of each Reorganization Agreement and the transactions contemplated therein, including amendments to the MQY Articles Supplementary in connection with the issuance of additional Acquiring Fund VRDP Shares, by the Acquiring Fund VRDP Holders voting as a separate class pursuant to the governing documents of the Acquiring Fund VRDP Shares. If Acquiring Fund VRDP Holders do not approve a Reorganization Agreement as a separate class, then the corresponding Reorganization will not occur.

Q:How does the Board of my Fund suggest that I vote?
A:After careful consideration, the Board of your Fund unanimously recommends that you vote “FOR” the proposal(s) relating to your Fund.
Q:When and where will the Special Meeting be held?
A:The Special Meeting will be held on October 15, 2025 at 2:00 pm (Eastern Time). The Special Meeting will be held in virtual meeting format only. Shareholders will not have to travel to attend the Special Meeting, but will be able to view the Special Meeting live, and cast their votes by accessing a web link. The Special Meeting will provide shareholders with a meaningful opportunity to participate, including the ability to ask questions of management. To support these efforts, the Funds will:

Questions relevant to Special Meeting matters will be answered during the Special Meeting, subject to time constraints.
•Engage with and respond to shareholders who ask questions relevant to Special Meeting matters that are not answered during the Special Meeting due to time constraints.
Q:How do I vote my proxy?

iv

Shareholders of record of each Fund as of the close of business on August 18, 2025 (the “Record Date”) are entitled to notice of and to vote at the Special Meeting or any adjournment or postponement thereof.

Shareholders of each Fund are entitled to one vote for each common share or VMTP Share or VRDP Share, as applicable (each, a “Share”), held, with no Shares having cumulative voting rights. Preferred shareholders of each Fund will have equal voting rights with the common shareholders of such Fund with respect to the proposals that require the vote of the Fund’s VMTP Shares or VRDP Shares, as applicable, and common shares as a single class. The quorum and voting requirements for each Fund are described in the section herein entitled “Vote Required and Manner of Voting Proxies.”

This Proxy Statement is only being delivered to the preferred shareholders of each Fund. Each Fund is separately soliciting the votes of its respective common shareholders on each of the foregoing proposals that require the vote of common shareholders and preferred shareholders as a single class through a separate joint proxy statement/prospectus and not through this Proxy Statement.

BKN, MYD, MQT and the Acquiring Fund are each incorporated as a Maryland corporation, BHV is formed as a Delaware statutory trust, and MPA is formed as a Massachusetts business trust. Each of BKN, MYD, MQT and the Acquiring Fund is a diversified, closed-end management investment company registered under the 1940 Act. Each of BHV and MPA is anon-diversified, closed-end management investment company registered under the 1940 Act. The Reorganizations seek to achieve certain economies of scale and other operational efficiencies by combining six funds that have similar investment objectives, investment strategies, policies and restrictions.

Assuming each of the Reorganizations receives the necessary approvals, the Acquiring Fund will acquire substantially all of the assets and assume substantially all of the liabilities of BKN, MYD, MQT, BHV and MPA in exchange solely for newly issued common shares and VRDP Shares of the Acquiring Fund in the form of book-entry interests. The Acquiring Fund will list the newly issued common shares on the New York Stock Exchange (“NYSE”). Such newly issued Acquiring Fund Shares will be distributed to BKN, MYD, MQT, BHV and MPA shareholders (although cash may be distributed in lieu of fractional common shares) and each of BKN, MYD, MQT, BHV and MPA will terminate its registration under the 1940 Act and liquidate, dissolve and terminate in accordance with its respective charter/declaration of trust and applicable state law. The Acquiring Fund will continue to operate after the Reorganizations as a registered, diversified, closed-end management investment company with the investment objective, investment strategies, investment policies and investment restrictions described in this Proxy Statement.

The Fund(s) in which you owned Shares on the Record Date is named on the proxy card. If you owned Shares in more than one Fund on the Record Date, you will receive more than one proxy card. Even if you plan to attend the Special Meeting, please sign, date and return EACH proxy card you receive or, if you provide voting instructions by telephone or via the Internet, please vote on each proposal affecting EACH Fund you own. If you vote by telephone or via the Internet, you will be asked to enter a unique code that has been assigned to you, which is printed on your proxy card(s). This code is designed to confirm your identity, provide access into the voting website and confirm that your voting instructions are properly recorded.

All properly executed proxies received prior to the Special Meeting will be voted in accordance with the instructions marked thereon or otherwise as provided therein. On any matter coming before the Special Meeting as to which a shareholder has specified a choice on that shareholder’s proxy, the Shares will be voted accordingly. If a proxy card is properly executed and returned and no

v choice is specified with respect to a proposal, the Shares will be voted “FOR” the proposal. Shareholders who execute proxies or provide voting instructions by telephone or via the Internet may revoke them with respect to a proposal at any time before a vote is taken on the proposal by filing with the applicable Fund a written notice of revocation (addressed to the Secretary of the Fund at the principal executive offices of the Fund at the New York address provided herein), by delivering a duly executed proxy bearing a later date or by attending the Special Meeting and voting by ballot, in all cases prior to the exercise of the authority granted in the proxy card. Merely attending the Special Meeting, however, will not revoke any previously executed proxy. If you hold Shares through a bank or other intermediary, please consult your bank or intermediary regarding your ability to revoke voting instructions after such instructions have been provided.

This Proxy Statement sets forth concisely the information that preferred shareholders of each Fund should know before voting on the proposals set forth herein. Please read it carefully and retain it for future reference. Copies of each Fund’s most recent annual report and semi-annual report can be obtained on a website maintained by BlackRock, Inc. (“BlackRock”) at

vi www.blackrock.com. In addition, each Fund will furnish, without charge, a copy of its most recent annual report or semi-annual report to any shareholder upon request. Any such request should be directed to BlackRock by calling (800)882-0052** **or by writing to the respective Fund at 100 Bellevue Parkway, Wilmington, Delaware 19809. The annual and semi-annual reports of each Fund are available on the EDGAR Database on the SEC’s website at www.sec.gov. The address of the principal executive offices of the Funds is 100 Bellevue Parkway, Wilmington, Delaware 19809, and the telephone number is (800)882-0052.

Each Fund is subject to the informational requirements of the Securities Exchange Act of 1934 (the “Exchange Act”) and the 1940 Act and, in accordance therewith, file reports, proxy statements, proxy materials and other information with the Securities and Exchange Commission (the “SEC”). Materials filed with the SEC can be downloaded from the SEC’s website at www.sec.gov. You may also request copies of these materials, upon payment at the prescribed rates of a duplicating fee, by electronic request to the SEC’se-mail address (publicinfo@sec.gov). Reports, proxy statements and other information concerning the Funds may also be inspected at the offices of the NYSE, 20 Broad Street, New York, New York 10005.

BlackRock updates performance information and certain other data for the Funds on a monthly basis on its website in the“Closed-End Funds” section of www.blackrock.com as well as certain other material information as necessary from time to time. Investors and others are advised to check the website for updated performance information and the release of other material information about the Funds. References to BlackRock’s website are intended to allow investors public access to information regarding the Funds and do not, and are not intended to, incorporate BlackRock’s website in this Proxy Statement.

Please note that only one copy of shareholder documents, including annual or semi-annual reports and proxy materials, may be delivered to two or more shareholders of the Funds who share an address, unless the Funds have received instructions to the contrary. This practice is commonly called “householding” and it is intended to reduce expenses and eliminate duplicate mailings of shareholder documents. Mailings of your shareholder documents may be householded indefinitely unless you instruct us otherwise. To request a separate copy of any shareholder document or for instructions as to how to request a separate copy of these documents or as to how to request a single copy if multiple copies of these documents are received, shareholders should contact the respective Fund at the address and phone number set forth above.

The common shares of BlackRock MuniYield Quality Fund, Inc. are listed on the NYSE under the ticker symbol “MQY” and will continue to be so listed after the completion of the Reorganizations.
