PIMCO Corporate & Income Opportunity Fund filed a Supplement dated June 24, 2026 that amends its Prospectus and Statement of Additional Information effective immediately. The supplement expands and clarifies that the Fund may invest in and/or originate loans (including whole loans, participations, assignments, secured and unsecured notes, senior and second lien loans, mezzanine and bridge loans) across corporate, consumer and mortgage-related exposures, including foreign borrowers.
The supplement states the Fund may invest without limit in mortgage-related and other asset-backed securities and will not normally invest more than 20% of total assets in debt instruments rated CCC or lower by S&P/Fitch or Caa1 or lower by Moody’s at purchase. The Fund may hold stressed, distressed or defaulted issuers and use credit default swaps; it may originate loans directly and hold them through wholly owned subsidiaries, subject to RIC qualification constraints and applicable licensing requirements.
PIMCO Corporate & Income Opportunity Fund (PTY) is changing its investment policies to take on more flexible, higher-risk credit strategies. Effective June 24, 2026, the Fund may, as a principal strategy, invest in and originate a wide range of loans to corporations, individuals and foreign borrowers, including subprime and below-investment-grade credits of various seniorities.
Effective July 24, 2026, the Fund may also invest without limit in defaulted bonds, subject to existing credit-quality limits such as normally keeping no more than 20% of total assets in non-ABS debt rated CCC/Caa1 or lower. The supplement details extensive risks around loan origination, illiquidity, subordination, regulatory licensing and potential litigation, and notes that many costs of originating and financing loans will be borne by the Fund rather than its adviser.
PIMCO Corporate & Income Opportunity Fund is revising its investment policy: effective August 28, 2026 the Fund will invest, under normal circumstances, at least 80% of its net assets (plus borrowings for investment purposes) in corporate debt obligations and/or income-producing investments, which may include instruments of non-corporate issuers. The revision expressly lists income-producing Fixed Income Instruments, dividend-paying equities, and derivatives that produce income or premium payments as within the 80% Policy. The prospectus supplement also states derivatives that provide exposure to policy investments or their market risk factors are expected to count toward the 80% Policy, clarifies derivative valuation methods (market, notional, or full exposure value), and requires the Fund to give shareholders at least 60 days written notice before changing the 80% Policy.

PIMCO’s closed-end funds PCM, PAXS, PCN, PDO and PTY have called a joint annual shareholder meeting for April 24, 2026 at PIMCO’s Newport Beach offices. Shareholders of each fund, as of the February 20, 2026 record date, will vote on the election or re-election of a slate of trustees, including independent nominees Mark Michel and Sonya Morris and interested trustee David Flattum.
The funds use a classified board structure with three trustee classes, so only part of each board is up for vote in any year, which supports continuity of oversight. Major broker-dealer platforms such as Charles Schwab and National Financial Services hold significant percentages of outstanding shares for several funds.
The proxy explains board governance, committee structure, trustee qualifications, compensation and meeting attendance, and confirms PricewaterhouseCoopers LLP as independent auditor, with disclosed audit and related fees for each fund.
