[Form 4/A] BANK OF AMERICA CORP /DE/ Amended Insider Trading Activity

Rhea-AI Filing Summary

Bank of America Corporation and its subsidiary Merrill Lynch, Pierce, Fenner & Smith Inc. jointly filed an amended Form 4 correcting two lines previously reported for trades in BlackRock Municipal Credit Alpha Portfolio, Inc. (MUNEX). The amendment sets the earliest transaction date as 09/25/2025 and clarifies the security title. The reported activity shows an indirect purchase of 4,780 shares at $12.64 followed the same day by an indirect sale of 4,780 shares at $12.68, leaving 0 shares beneficially owned after the transactions. The filing states Bank of America holds the interest indirectly through its 100% ownership of Merrill Lynch and disclaims beneficial ownership except to the extent of any pecuniary interest. The reporting parties also note that, without conceding Section 16(b) applicability, any short-swing profit potentially recoverable would be remitted to the issuer.

Positive

• Amendment corrects transaction date and security title, improving disclosure clarity
• Matched buy and sell of 4,780 shares left no residual position, simplifying ongoing reporting
• Commitment to remit any recoverable short-swing profit reduces potential unresolved compliance exposure

Negative

• Initial filing errors required an amendment to correct trade details
• No beneficial ownership remains following the trades, so there is no ongoing insider stake reported

Insights

Corporate Governance Analyst

TL;DR: An amended insider report corrects trade details and shows matched buy/sell of 4,780 shares on 09/25/2025.

The amendment fixes the transaction date and security title for two entries and clarifies that the interest is held indirectly through Merrill Lynch, a wholly owned subsidiary. Correcting such metadata improves transparency about which entity exercised trading authority.

The matched purchase and sale at $12.64 and $12.68 respectively produced no retained position, reducing ongoing insider ownership disclosure. Watch for any related filings if the issuer requests recovery under Section 16(b) within the statutory period.

Securities Compliance Specialist

TL;DR: The filing includes a compliance-safe declaration about potential short-swing profit remittance.

The reporting persons explicitly state they do not concede greater-than-10% beneficial owner status and reserve that the filing is not an admission under Section 13(d). They also commit that any potential short-swing profit, if applicable, will be remitted to the issuer.

This language is a common protective formulation; investors and compliance officers should note the commitment to remit recoverable amounts and monitor whether the issuer pursues recovery or accepts the filing as corrective documentation.

Explanation of Responses:

1. This statement is jointly filed by Bank of America Corporation and Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch") (collectively, the "Reporting Persons") to amend the two lines of transaction information disclosed in Table 1 by the Reporting Persons on September 29, 2025. The amendment reflects the correct Title of Security for each trade and the correct Date of Earliest Transaction Required to be Reported. Bank of America Corporation holds an indirect interest in the securities listed in this Report by virtue of its 100% ownership of its subsidiary Merrill Lynch. Each Reporting Person disclaims beneficial ownership of the securities reported herein except to the extent of its pecuniary interest therein, if any, and this report shall not be deemed an admission that any such Reporting Person is the beneficial owner of, or has any pecuniary interest in, such securities for purposes of Securities Exchange Act of 1934 (the "Exchange Act"), or for any other purpose.

2. Each Reporting Person declares that neither the filing of this statement nor anything herein shall be construed as an admission that such person is, for the purposes of Section 13(d) of the Exchange Act or any other purpose, (i) acting (or has agreed or is agreeing to act together with any other person) as a partnership, limited partnership, syndicate or other group for the purpose of acquiring, holding or disposing of securities of the Issuer or otherwise with respect to the Issuer or any securities of the Issuer or (ii) a member of any group with respect to the Issuer or any securities of the Issuer.

3. 3. Without conceding its status as a greater than 10% beneficial owner or that the reported transactions are subject to disclosure under Section 16(a) of the Exchange Act or short-swing profit recovery under Section 16(b) of the Exchange Act, the amount of profit potentially recoverable by the Issuer from the reported transactions in the event that the Reporting Persons were greater than 10% beneficial owners and the transactions were subject to Section 16(b) will be remitted to the Issuer.
