[SCHEDULE 13D/A] Pioneer Municipal High Income Advantage Fund, Inc. SEC Filing

Rhea-AI Filing Summary

Amendment No. 4 to Schedule 13D reports that Bank of America Corporation and Banc of America Preferred Funding Corp previously owned 500 Variable Rate MuniFund Term Preferred Shares (CUSIP 723762407) of Pioneer Municipal High Income Advantage Fund, Inc. Those 500 VMTP Shares were redeemed by the issuer on August 18, 2025 for the liquidation preference plus accumulated unpaid dividends. As a result of the redemption the Reporting Persons no longer own any VMTP Shares (CUSIP 723762407) and ceased to be beneficial owners of more than 5% of that class. The amendment replaces certain schedules and updates exhibits, including a joint filing agreement and power of attorney.

Positive

• None.

Negative

• Reporting persons no longer own any VMTP Shares (CUSIP 723762407), reducing disclosed large-holder ownership to zero
• Ceased to be beneficial owners of more than 5% of the class as of August 18, 2025, which may affect market transparency for that security

Insights

Securities Analyst

TL;DR: Reporting persons’ stake in the VMTP class was fully redeemed, reducing disclosed ownership to zero and removing >5% ownership.

The filing documents a routine issuer-initiated redemption of 500 VMTP shares (CUSIP 723762407) on August 18, 2025, with payment of liquidation preference and accrued dividends. For public investors this is a mechanical change in beneficial ownership: the reporting entities—Bank of America Corporation and Banc of America Preferred Funding Corp—no longer hold the class and the Schedule 13D was amended to reflect that fact and to update exhibits and schedules. There is no new operational or financial detail about the issuer beyond the redemption event.

Corporate Governance Expert

TL;DR: The amendment formalizes the end of a >5% reporting relationship following a share redemption by the issuer.

The amendment serves primarily to update disclosure and replace previously filed schedules and exhibits. It confirms that the reporting persons ceased to be >5% beneficial owners as of the redemption date and includes replacement exhibits (joint filing agreement, power of attorney, updated schedules). This is procedural disclosure compliance rather than a strategic change by the reporting entities; it reduces the pool of large disclosed holders for this preferred-share class.
