Notes to Financial Statements | 4/30/22

(unaudited)

1. Organization

Pioneer ILS Bridge Fund (the "Fund") was organized under the laws of the State of Delaware on June 20, 2016 and was registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended (the 1940 Act) as a non-diversified, closed-end management investment company. The Fund's investment objective is total return.

The initial fund shares were issued on June 22, 2018 to Amundi Asset Management US, Inc. (the "Adviser"), an indirect, wholly owned subsidiary of Amundi Asset Management Co. and Amundi's wholly owned subsidiary, Amundi USA, Inc. In addition, the Adviser has agreed to pay all organizational and offering costs of the Fund.

As of April 30, 2022, the Fund has not commenced operations and has not executed any transactions other than these relating to organizational matters and the issuance of initial shares to the Adviser as described above. As of April 30, 2022, the Adviser was the sole shareholder of the Fund.

The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") that require the management of the Fund to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting period. Actual results could differ from those estimates.

2. Fund Shares

The Fund will offer shares through Amundi Distributor US, Inc., the principal underwriter for the Fund. Shares will be offered at the Fund's current net asset value ("NAV") per share. The Fund does not have an unlimited number of shares registered. Shares are not currently offered.

The Fund is an "interval" fund and will make periodic offers to repurchase shares. Except as permitted by the Fund's structure, no shareholder will have the right to require the Fund to repurchase its shares. No public market for shares exists, and none is expected to develop in the future. Consequently, shareholders generally will not be able to liquidate their investment other than as a result of repurchases of their shares by the Fund.

Pioneer ILS Bridge Fund | Semiannual Report | 4/30/22 5

The Fund will offer to repurchase at least 5% and up to 25% of its shares at NAV on a regular schedule. The Fund's policy permits repurchases of between 5% and 25% of the Fund's outstanding shares for each repurchase offer. The Fund will typically conduct quarterly repurchase offers for 10% of the Fund's outstanding shares at their NAV per share, subject to applicable law and approval of the Board of Trustees.

The schedule requires the Fund to make repurchase offers every three months. Quarterly repurchase offers occur in the months of January, April, July and October. In the event a repurchase offer by the Fund is oversubscribed, the Fund may repurchase, but is not required to repurchase, additional shares up to a maximum amount of 2% of the outstanding shares of the Fund. If the Fund determines not to repurchase additional shares beyond the repurchase offer amount, or if shareholders submit for repurchase an amount of shares greater than that which the Fund is entitled to repurchase, the Fund will repurchase the shares submitted for repurchase on a pro rata basis. The Fund has no repurchases as of April 30, 2022.

3. Management Agreement

The Adviser manages the Fund's portfolio. Management fees will be calculated daily and paid monthly at the annual rate of 1.75% on the Fund's average daily net assets. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, will be paid by the Fund. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $3 in administrative costs payable to the Adviser at April 30, 2022. The Fund did not incur or pay any management fees during the six months ended April 30, 2022.

4. Compensation of Trustees and Officers

The Fund pays an annual fee to its Trustees. The Adviser reimburses the Fund for fees paid to the Interested Trustees. The Fund does not pay any salary or other compensation to its officers. For the six months ended April 30, 2022, the Fund paid $0 in Trustees' compensation, which is reflected on the Statement of Operations as Trustees' fees. At April 30, 2022, the Fund had a payable for Trustees' fees on its Statement of Assets and Liabilities of $0.

5. Transfer Agent

For the period from November 1, 2021 to November 21, 2021, DST Asset Manager Solutions, Inc. served as the transfer agent to the Fund at negotiated rates. Effective November 22, 2021, BNY Mellon Investment Servicing (US) Inc. serves as the transfer agent to the Fund at negotiated

6 Pioneer ILS Bridge Fund | Semiannual Report | 4/30/22

rates. Transfer agent fees and payables shown on the Statement of Operations and the Statement of Assets and Liabilities, respectively, include sub-transfer agent expenses incurred through the Fund's omnibus relationship contracts.

In addition, the Fund reimbursed the transfer agent for out-of-pocket expenses incurred by the transfer agent related to shareowner communications activities such as proxy and statement mailings, and outgoing phone calls. For the six months ended April 30, 2022, such out-of-pocket expenses by class of shares were as follows:

Shareowner Communications:
Fund	$59
Total	$59

6. Federal Income Taxes

The Fund intends to qualify as a "regulated investment company" and to comply with the applicable provisions of the Internal Revenue Code, such that it will not be subject to federal income tax on taxable income (including realized capital gains) that is distributed to shareholders.

7. Expense Reimbursements

The Adviser has agreed to reimburse all organizational and offering costs, estimated at approximately $47,503. The Adviser directly provided certain organizational services to the Fund at no expense. This amount is disclosed in the Statement of Operations.

8. Risk

The global pandemic of the novel coronavirus respiratory disease designated COVID-19 has resulted in major disruption to economies and markets around the world, including the United States. Global financial markets have experienced extreme volatility and severe losses, and trading in many instruments has been disrupted. Liquidity for many instruments has been greatly reduced for periods of time. Some sectors of the economy and individual issuers have experienced particularly large losses. These circumstances may continue for an extended period of time, and may continue to affect adversely the value and liquidity of the Fund's investments. Following Russia's recent invasion of Ukraine, Russian securities have lost all, or nearly all, their market value. Other securities or markets could be similarly affected by past or future geopolitical or other events or conditions.

Governments and central banks, including the U.S. Federal Reserve, have taken extraordinary and unprecedented actions to support local and global

Pioneer ILS Bridge Fund | Semiannual Report | 4/30/22 7

economies and the financial markets. These actions have resulted in significant expansion of public debt, including in the U.S. The consequences of high public debt, including its future impact on the economy and securities markets, may not be known for some time.

Russia launched a large-scale invasion of Ukraine on February 24, 2022. In response to the military action by Russia, various countries, including the U.S., the United Kingdom, and European Union issued broad-ranging economic sanctions against Russia and Belarus and certain companies and individuals. Since then, Russian securities have lost all, or nearly all, their market value, and many other issuers, securities and markets have been adversely affected. The United States and other countries may impose sanctions on other countries, companies and individuals in light of Russia's military invasion. The extent and duration of the military action or future escalation of such hostilities, the extent and impact of existing and future sanctions, market disruptions and volatility, and the result of any diplomatic negotiations cannot be predicted. These and any related events could have a significant impact on the value and liquidity of certain Fund investments, on Fund performance and the value of an investment in the Fund, particularly with respect to securities and commodities, such as oil and natural gas, as well as other sectors with exposure to Russian issuers or issuers in other countries affected by the invasion, and are likely to have collateral impacts on market sectors globally.

9. Changes in Custodian and Sub-Administrator, and Transfer Agent

Effective November 22, 2021, The Bank of New York Mellon Corporation ("BNY Mellon") serves as the Fund's Custodian and Sub-Administrator. Effective November 22, 2021, BNY Mellon Investment Servicing (US) Inc. serves as the Fund's shareholder servicing and transfer agent.

PIONEER FUNDS

APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES

PROVIDED BY THE INDEPENDENT AUDITOR

SECTION I - POLICY PURPOSE AND APPLICABILITY

The Pioneer Funds recognize the importance of maintaining the independence of their outside auditors. Maintaining independence is a shared responsibility involving Amundi Asset Management US, Inc., the audit committee and the independent auditors.

The Funds recognize that a Fund's independent auditors: 1) possess knowledge of the Funds, 2) are able to incorporate certain services into the scope of the audit, thereby avoiding redundant work, cost and disruption of Fund personnel and processes, and 3) have expertise that has value to the Funds. As a result, there are situations where it is desirable to use the Fund's independent auditors for services in addition to the annual audit and where the potential for conflicts of interests are minimal. Consequently, this policy, which is intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and procedures to be followed by the Funds when retaining the independent audit firm to perform audit, audit-related tax and other services under those circumstances, while also maintaining independence.

Approval of a service in accordance with this policy for a Fund shall also constitute approval for any other Fund whose pre-approval is required pursuant to Rule 210.2-01(c)(7)(ii).

In addition to the procedures set forth in this policy, any non-audit services that may be provided consistently with Rule 210.2-01 may be approved by the Audit Committee itself and any pre-approval that may be waived in accordance with Rule 210.2-01(c)(7)(i)(C) is hereby waived.

Selection of a Fund's independent auditors and their compensation shall be determined by the Audit Committee and shall not be subject to this policy.
