This proxy statement (this “Proxy Statement”) and the enclosed GOLD proxy card are being furnished by Saba Capital Management, L.P. (“Saba Capital”) and Boaz R. Weinstein (“Mr. Weinstein,” and together with Saba Capital, “Saba,” “we,” “us” or the “Participants”), in connection with the solicitation of proxies from the shareholders of BlackRock Investment Quality Municipal Trust, Inc., a Maryland corporation and closed-end management investment company registered under the Investment Company Act of 1940, as amended (the “Fund”), at the joint special meeting of shareholders of the Fund (including any adjournments or postponements thereof, the “Special Meeting”).

The Fund is asking shareholders to approve a merger whereby the Fund would be merged with and into a Maryland limited liability company and a wholly-owned subsidiary of BlackRock MuniYield Quality Fund III, Inc., a Maryland corporation (the “Acquiring Fund”), with the issued and outstanding common and preferred shares of the Fund being converted into newly issued common and preferred shares of the Acquiring Fund, respectively (the “Merger”). Pursuant to the Merger, the Fund would cease to exist.

We believe shareholders should vote against the Merger, which Saba does not believe to be fair value consideration for the Fund’s shareholders. The Fund trades at a steep 14.05% discount to net asset value (“NAV”).¹ The Acquiring Fund trades at an even steeper 15.29% discount to NAV.² Saba believes the Fund should be focused on achieving better performance and getting shareholders the true value of their shares, i.e. NAV, instead of depleting their value further by merging with a fund that trades at a further discount to NAV.

We are seeking your support at the upcoming Special Meeting, that is scheduled to be held virtually via live webcast on [●], 2023 at [●], Eastern Time.

This Proxy Statement and the enclosed GOLD proxy card are first being furnished to the Fund’s shareholders on or about [●], 2023.

Saba is seeking your support at the Special Meeting with respect to the following proposals (each a “Proposal” and collectively the “Proposals”) and to consider and act upon any other business that may properly come before the Special Meeting.

According to the Fund’s Declaration of Trust and the Amended and Restated Certificate of Designation (collectively, the “Charter”) and the Fund’s joint proxy statement/prospectus for the Special Meeting (the “Fund’s Proxy Statement”), approval of the Merger by shareholders of the Fund requires (i) with respect to Proposal 1(C), the affirmative vote of the holders of a majority of the votes entitled to be cast by outstanding Common Shares and VMTP Shares of the Fund voting as a single class; and (ii) with respect to Proposal 1(D), the affirmative vote of the holders of lesser of (a) more than 50% of the outstanding VMTP Shares of the Fund, or (b) 67% or more of the VMTP Shares of the Fund present (in person or by proxy) at the Special Meeting if more than 50% of the outstanding VMTP Shares of the Fund are present at the Special Meeting in person or by proxy (“1940 Act Majority”) voting as a separate class. According to the Fund’s Proxy Statement, approval of the Merger also requires the affirmative vote of the holders of a 1940 Act Majority of VMTP Shares of the Acquiring Fund, voting as a separate class.

Through this Proxy Statement and enclosed GOLD proxy card, we are soliciting proxies opposing each of the Proposals. We strongly oppose the approval of the Merger and urge shareholders to vote “AGAINST” Proposal 1.

The Fund has set the record date for determining shareholders entitled to notice of and to vote at the Special Meeting (the “Record Date”) as [●], 2023. Shareholders of record at the close of business on the Record Date will be entitled to vote at the Special Meeting. As of the close of business on the Record Date, the Participants may be deemed to “beneficially own” (such term as used in Schedule 14A within the meaning of Rule 13d-3 or Rule 16a-1 under the Securities Exchange Act of 1934 (the “Exchange Act”)), in the aggregate, [●] Common Shares, as further described in Annex I. There were [●] Common Shares and [●] VMTP Shares of the Fund outstanding as of the Record Date according to the Fund’s Proxy Statement.

We urge you to sign, date and return the GOLD proxy card voting “AGAINST” Proposal 1. By returning the GOLD proxy card, you are authorizing Saba to vote on your behalf, and if you do not indicate how you would like to vote, your vote will be counted “AGAINST” Proposal 1.

Saba intends to deliver this Proxy Statement and the accompanying form of GOLD proxy card to holders of at least the percentage of the Fund’s voting shares required under applicable law to oppose each of the Proposals at the Special Meeting and otherwise intends to solicit proxies or votes from shareholders of the Fund in opposition to the passage of the Proposals. This proxy solicitation is being made by Saba and not on behalf of the board of directors of the Fund (the Board”) or management of the Fund or any other third party. We are not aware of any other matters to be brought before the Special Meeting other than as described herein. Should other matters be brought before the Special Meeting, the persons named as proxies in the enclosed GOLD proxy card will vote on such matters in their discretion to the extent allowed by Rule 14a-4(c)(3) under the Exchange Act.

If you have already voted using the Fund’s proxy card, you have every right to change your vote by completing and mailing the enclosed GOLD proxy card in the enclosed pre-paid envelope or by voting via Internet or by telephone by following the instructions on the GOLD proxy card. Importantly, only the latest validly executed proxy that you submit will be counted. In addition, any proxy may be revoked at any time prior to its exercise at the Special Meeting by following the instructions under “Can I change my vote or revoke my proxy?” in the Questions and Answers section.

For instructions on how to vote, including the quorum and voting requirements for the Fund and other information about the proxy materials, see the Questions and Answers section.

If you have any questions or require any assistance with voting your shares, please contact our proxy solicitor, InvestorCom, toll free at (877) 972-0090 or collect at (203) 972-9300.

As a significant shareholder of the Fund, Saba is committed to improving the Fund for the benefit of all shareholders and, to this end, is opposing the approval of the Merger.

We believe shareholders should vote against the Merger, which Saba does not believe to be fair value consideration for the Fund’s shareholders. The Fund trades at a steep 14.05% discount to NAV.³ The Acquiring Fund trades at an even steeper 15.29% discount to NAV.⁴ Saba believes the Fund should be focused on achieving better performance and getting shareholders the true value of their shares, i.e. NAV, instead of depleting their value further by merging with a fund that trades at a further discount to NAV.

For the foregoing reasons, we urge you to join us and vote “AGAINST” Proposal 1 on the GOLD proxy card today.

The Fund and the Acquiring Fund’s investment advisor, BlackRock Advisors, LLC, has recommended a merger of the Fund into a wholly-owned subsidiary of the Acquiring Fund. At a meeting held on September 8, 2023, the Board and the board of directors of the Acquiring Fund each approved the Merger, and recommended that shareholders of each respective fund approve the Merger.

According to the Fund’s Proxy Statement, as part of the Merger, the Common Shareholders will receive newly issued common shares of the Acquiring Fund that (except for cash payments received in lieu of fractional common shares) will have an aggregate NAV (not the market value) immediately after the effective date of the Merger, which is expected to be during the first half of 2024 (the “Closing Date”) equal to the aggregate NAV (not the market value) of that shareholder’s Common Shares immediately prior to the Closing Date. The aggregate NAV of the Fund immediately prior to the Merger will reflect accrued expenses associated with such Merger. The value of the Fund’s net assets will be calculated net of the liquidation preference (including accumulated and unpaid dividends) of any outstanding VMTP Shares of the Fund.

According to the Fund’s Proxy Statement, prior to the Closing Date, the Fund will redeem all of its outstanding VMTP Shares and may issue Variable Rate Demand Preferred Shares (“VRDP Shares”) of the Fund with terms substantially identical to the terms of the Acquiring Fund’s VRDP Shares and use the proceeds from such issuance for the redemption of all of the outstanding VMTP Shares of the Fund (the “VMTP Refinancing”). If the Fund has any VMTP Shares outstanding as of, and the VMTP Refinancing is not completed prior to, the Closing Date, then the Merger will not be consummated. Please refer to the Fund’s Proxy Statement for further details on the effects of the Merger on the VMTP Shares of the Fund.

We oppose the approval of the Merger as we believe it is not in the best interests of the Fund and its shareholders to trade their current shares for those of the Acquiring Fund which trade at a more significant discount to NAV.

For these reasons, we recommend voting “AGAINST” Proposal 1. The Participants intend to vote all of their Common Shares “AGAINST” Proposal 1(C). The Participants did not hold any VMTP Shares of the Fund as of the Record Date and thus are not entitled to vote on Proposal 1(D).

Vote Required. According to the Charter and the Fund’s Proxy Statement, approval of the Merger requires (i) with respect to Proposal 1(C), the affirmative vote of the holders of a majority of the votes entitled to be cast by outstanding Common Shares and VMTP Shares voting as a single class and (ii) with respect to Proposal 1(D), the affirmative vote of the holders of a 1940 Act Majority of VMTP Shares voting as a separate class. According to the Fund’s Proxy Statement, approval of the Merger also requires the affirmative vote of the holders of a 1940 Act Majority of VMTP Shares of the Acquiring Fund, voting as a separate class.

Abstentions will have the same effect as votes “against” Proposal 1(C) and Proposal 1(D). For information on the treatment of broker non-votes, if any, in connection with the Special Meeting, please see the Fund’s Proxy Statement.

Only holders of Common Shares and VMTP Shares (together with the Common Shares, the “Shares”) at the close of business on the Record Date are entitled to notice of and to vote at the Special Meeting. Shareholders who sold their Shares before the Record Date (or acquire them without voting rights after the Record Date) may not vote such Shares. Shareholders of record on the Record Date will retain their voting rights in connection with the Special Meeting even if they sell such Shares after the Record Date (unless they also transfer their voting rights as of the Record Date).

Shares held in record name. If your Shares are registered in your own name, please vote today by signing, dating and returning the enclosed GOLD proxy card in the postage-paid envelope provided. Execution and delivery of a proxy by a record holder of Shares will be presumed to be a proxy with respect to all Shares held by such record holder unless the proxy specifies otherwise.

Shares beneficially owned or held in “street” name. If you hold your Shares in “street” name with a broker, bank, dealer, trust company or other nominee, only that nominee can exercise the right to vote with respect to the Shares that you beneficially own through such nominee and only upon receipt of your specific instructions. Accordingly, it is critical that you promptly give instructions to your broker, bank, dealer, trust company or other nominee to vote AGAINST Proposal 1. Please follow the instructions to vote provided on the enclosed GOLD voting instruction form. If your broker, bank, dealer, trust company or other nominee provides for proxy instructions to be delivered to them by telephone or Internet, instructions will be included on the enclosed GOLD voting instruction form. We urge you to confirm in writing your instructions to the person responsible for your account and provide a copy of those instructions by emailing them to Saba@investor-com.com or mailing them to Saba Capital Management, L.P., c/o InvestorCom, 19 Old Kings Highway S., Suite 130, Darien, CT 06820, so that we will be aware of all instructions given and can attempt to ensure that such instructions are followed.

Note: Shares represented by properly executed GOLD proxy cards will be voted at the Special Meeting as marked and, in the absence of specific instructions, “AGAINST” Proposal 1.

According to the Charter and the Fund’s Proxy Statement, the presence in person or by proxy at the Special Meeting of the holders of the Shares entitled to cast one-third of the votes entitled to be cast shall constitute a quorum for the transaction of business on that matter at the Special Meeting. According to the Fund’s Proxy Statement, abstentions are treated as votes present for purposes of determining a quorum. For information on the treatment of broker non-votes, if any, in connection with the Special Meeting, please see the Fund’s Proxy Statement.

Approval of the Merger. Based on the Fund’s Proxy Statement, the approval of the Merger by shareholders of the Fund requires (i) with respect to Proposal 1(C), the affirmative vote of a the holders of a majority of the votes entitled to be cast by outstanding Common Shares and VMTP Shares voting as a single class and (ii) with respect to Proposal 1(D), the affirmative vote of the holders of a 1940 Act Majority of VMTP Shares voting as a separate class. According to the Fund’s Proxy Statement, approval of the MPA Merger Agreement also requires the affirmative vote of the holders of a 1940 Act Majority of VMTP Shares of the Acquiring Fund, voting as a separate class.

You may receive proxy solicitation materials from the Fund, including an opposition proxy statement and a proxy card. We are not responsible for the accuracy of any information contained in any proxy solicitation materials used by the Fund or any other statements that it may otherwise make.

We recommend that you discard any proxy card or solicitation materials that may be sent to you by the Fund. If you have already voted using the Fund’s proxy card, you have every right to change your vote by using the enclosed GOLD proxy card by signing, dating and returning the enclosed GOLD proxy card in the postage-paid envelope provided. Only the latest validly executed proxy that you submit will be counted; any proxy may be revoked at any time prior to its exercise at the Special Meeting by following the instructions below under “Can I change my vote or revoke my proxy?”

If you have any questions or require any assistance with voting your Shares, please contact our proxy solicitor, InvestorCom. Shareholders may call toll free at (877) 972-0090 or collect at (203) 972-9300.

If you are the shareholder of record, you may change your proxy instructions or revoke your proxy at any time before your proxy is voted at the Special Meeting. Proxies may be revoked by any of the following actions:

If your Shares are held in a brokerage account by a broker, bank or other nominee, you should follow the instructions provided by your broker, bank or other nominee. If you attend the Special Meeting and you beneficially own Shares but are not the record owner, your mere attendance at the Special Meeting WILL NOT be sufficient to revoke any previously submitted proxy card. You must have written authority from the record owner to vote your Shares held in its name at the meeting in the form of a “legal proxy” issued in your name from the bank, broker or other nominee that holds your Shares. If you have any questions or require any assistance with voting your Shares, please contact our proxy solicitor, InvestorCom, toll free at (877) 972-0090 or collect at (203) 972-9300.

IF YOU HAVE ALREADY VOTED USING THE FUND’S PROXY CARD, WE URGE YOU TO REVOKE IT BY FOLLOWING THE INSTRUCTIONS ABOVE. Although a revocation is effective if delivered to the Fund, we request that a copy of any revocation be mailed to Saba Capital Management, L.P., c/o InvestorCom, 19 Old Kings Highway S., Suite 130, Darien, CT 06820, so that we will be aware of all revocations.

The solicitation of proxies pursuant to this proxy solicitation is being made by the Participants. Proxies may be solicited by mail, facsimile, telephone, telegraph, Internet, in person or by advertisements. Saba will solicit proxies from individuals, brokers, banks, bank nominees and other institutional holders. Saba will request banks, brokerage houses and other custodians, nominees and fiduciaries to forward all solicitation materials to the beneficial owners of the Shares they hold of record. Saba will reimburse these record holders for their reasonable out-of-pocket expenses in so doing. It is anticipated that certain regular employees of Saba will also participate in the solicitation of proxies in opposition of the Proposals. Such employees will receive no additional consideration if they assist in the solicitation of proxies.

Saba has retained InvestorCom to provide solicitation and advisory services in connection with this solicitation. InvestorCom will be paid a fee not to exceed $[●] based upon the campaign services provided. In addition, Saba will advance costs and reimburse InvestorCom for reasonable out-of-pocket expenses and will indemnify InvestorCom against certain liabilities and expenses, including certain liabilities under the federal securities laws. InvestorCom will solicit proxies from individuals, brokers, banks, bank nominees and other institutional holders. It is anticipated that InvestorCom will employ approximately [●] persons to solicit the Fund’s shareholders as part of this solicitation. InvestorCom does not believe that any of its owners, managers, officers, employees, affiliates or controlling persons, if any, is a “participant” in this proxy solicitation.

The entire expense of soliciting proxies is being borne by Saba. Costs of this proxy solicitation are currently estimated to be approximately $[●]. We estimate that through the date hereof, Saba’s expenses in connection with the proxy solicitation are approximately $[●]. If successful in its proxy solicitation, Saba may seek reimbursement of these costs from the Fund. For the avoidance of doubt, such reimbursement is not guaranteed. In the event that Saba decides to seek reimbursement of its expenses, Saba does not intend to submit the matter to a vote of the Fund’s shareholders. The members of the Board would be required to evaluate the requested reimbursement consistent with their fiduciary duties to the Fund and its shareholders.

The Securities and Exchange Commission (the “SEC”) has adopted rules that permit companies and intermediaries (such as brokers and banks) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more shareholders sharing the same address by delivering a single proxy statement addressed to those shareholders. Some banks and brokers with account holders who are shareholders of the Fund may be householding our proxy materials.

A single copy of this Proxy Statement (and of the Fund’s Proxy Statement) will be delivered to multiple shareholders sharing an address unless contrary instructions have been received from one or more of the affected shareholders. Once you have received notice from your bank or broker that it will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement, please notify your bank or broker and direct your request to the Fund at 100 Bellevue Parkway, Wilmington, Delaware 19809, or by calling toll free at (800) 882-0052. Shareholders who currently receive multiple copies of this Proxy Statement at their address and would like to request householding of their communications should contact their bank or broker.

Because Saba has initiated a contested proxy solicitation, we understand that banks and brokers with account holders who are shareholders of the Fund will not be householding our proxy materials.

Pursuant to Rule 14a-5(c) promulgated under the Exchange Act, we have omitted from this Proxy Statement certain disclosure required by applicable law to be included in the Fund’s Proxy Statement. We take no responsibility for the accuracy or completeness of any information that we expect to be contained in the Fund’s Proxy Statement. Except as otherwise noted herein, the information in this Proxy Statement concerning the Fund has been taken from or is based upon documents and records on file with the SEC and other publicly available information.

This Proxy Statement and all other solicitation materials in connection with this proxy solicitation will be available on the internet, free of charge, on the SEC’s website at https://www.edgar.sec.gov. The Edgar file number for the Fund is 811-07354.

We urge you to carefully consider the information contained in this Proxy Statement and then support our efforts by signing, dating and returning the enclosed GOLD proxy card today.

This proxy solicitation is being made by the Participants. As of the date of this Proxy Statement, the Participants may be deemed to “beneficially own” (such term as used in Schedule 14A within the meaning of Rule 13d-3 or Rule 16a-1 under the Exchange Act for the purposes of this Annex I) 1,500 Common Shares in the aggregate. Of the 1,500 Common Shares owned in the aggregate by the Participants, such Common Shares may be deemed to be beneficially owned as follows: (a) 1,500 Common Shares may be deemed to be beneficially owned by Saba Capital by virtue of its status as the investment manager of various funds and accounts, such funds and accounts, the (“Saba Entities”); and (b) 1,500 Common Shares may be deemed to be beneficially owned by Mr. Weinstein by virtue of his status as the principal of Saba.

In such instances, the positions held in the margin account are pledged as collateral security for the repayment of debit balances in the account. The margin accounts bear interest at a rate based upon the broker’s call rate from time to time in effect. Because other securities are held in the margin accounts, it is not possible to determine the amounts, if any, of margin used to purchase the Common Shares reported herein since margin may have been attributed to such other securities and since margin used is not disclosed on an individual per-security basis.
