Tax-Free Income from a Selective Portfolio of High-Yield Municipal Bonds


Pioneer High Income Municipal Fund

Y-Share: HIMYX | A-Share: PIMAX | C-Share: HICMX

The Fund seeks to maximize total return through a combination of income that is exempt from regular federal income tax and capital appreciation. The Fund puts an emphasis on managing downside risk. The Fund aims to invest primarily in the most attractive opportunities in the high yield municipal bond market focused on issues tied to financing the fundamentals of the US economy.


Reduced Fees & Expenses on Certain Amundi US Funds

Effective November 8, 2021, the breakpoint at which purchases may be made with no initial sales charge (net asset value) for Pioneer AMT-Free Municipal Fund and Pioneer High Income Municipal Fund will be reduced from $500,000 to $250,000 for Class A shares, potentially subject to a 1% contingent deferred sales charge within 12 months.

Effective October 1, 2021, fees and expenses have been reduced for three Pioneer funds, for certain share classes, lowering costs for shareholders: Pioneer Strategic Income FundPioneer AMT-Free Municipal Fund and Pioneer Disciplined Value Fund.

A Focus on Sector Diversity and Risk Management

Pioneer High Income Municipal Fund seeks to provide high-net-worth investors with attractive tax-exempt income, emphasizing nationally diverse sectors and downside risk management. We believe rigorous risk management is essential for pursuing the strongest opportunities in an economic and market environment characterized by transition.


Highly Diversified Across Sectors & States

The Fund's portfolio provides exposure to high yield municipal bonds offering diversification* across sectors and states. Understanding fundamental variations in laws and regulations from state-to-state, helps differentiate the quality of municipal bonds within the same sector. Our top sectors are typically comprised of multiple separate and independent bonds across multiple states.

Focus on Risk Management

Strict due diligence is the bedrock of our Fund. We believe the combination of our investment team's on-site due diligence of each issuer and the Fund’s geographic diversification* across sectors, such as tobacco bonds, charter schools and assisted living facilities, can reduce loss by helping limit the risk of defaults. No leverage reduces investor exposure to additional risks beyond credit risk.

Specialized Management Expertise

The investment team’s approach to managing the Fund is designed to seek total return while preventing permanent loss of capital. Their specialized expertise enables them to explore a variety of non-traditional sectors that may provide long-term opportunities for enhanced total return. The team is actively involved in the research and trading process, providing a deeper and broader perspective of opportunities in the municipal bond market.

 * Diversification does not ensure a profit or a loss.

There can be no assurance that Amundi US will extend the expense limitations beyond such time. Please see the prospectus and financial statements for more information. Class Y shares are not subject to sales charges and are available for limited groups of investors, including institutional investors.

A Word About Risk

The market prices of securities may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic, political, or regulatory conditions, recessions, inflation, changes in interest or currency rates, lack of liquidity in the bond markets, the spread of infectious illness or other public health issues or adverse investor sentiment. Investments in high yield or lower-rated securities are subject to greater-than-average price volatility, illiquidity and possibility of default. When interest rates rise, the prices of fixed income securities in the Fund will generally fall. Conversely, when interest rates fall, the prices of fixed income securities in the Fund will generally rise. Investments in the Fund are subject to possible loss due to the financial failure of issuers of underlying securities and their inability to meet their debt obligations. Prepayment risk is the chance that an issuer may exercise its right to prepay its security, if falling interest rates prompt the issuer to do so. Forced to reinvest the unanticipated proceeds at lower interest rates, the fund would experience a decline in income and lose the opportunity for additional price appreciation. The value of municipal securities can be adversely affected by changes in financial condition of municipal issuers, lower revenues, and regulatory and political developments. The Fund may use derivatives, such as options, futures, inverse floating rate obligations, swaps, and others, which can be illiquid, may disproportionately increase losses, and have a potentially large impact on Fund performance. Derivatives may have a leveraging effect on the Fund. A portion of income may be subject to local, state, federal and/or alternative minimum tax. Capital gains, if any, are subject to a capital gains tax. At times, the Fund’s investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. These risks may increase share price volatility.
