PIMCO CORPORATE & INCOME STRATEGY FUND 8-K

What Happened PIMCO Corporate & Income Strategy Fund (PCN) filed an 8-K on June 24, 2026 reporting that its Board of Trustees approved a change to the Fund’s 80% investment policy on June 23, 2026. Effective August 28, 2026, the Fund will, under normal circumstances, invest at least 80% of its net assets (plus any borrowings for investment purposes) in corporate debt obligations of varying maturities and/or other income-producing investments, and the policy expressly allows those investments to include instruments of non-corporate issuers. A prospectus supplement and updated statement of additional information reflecting the change is attached to the filing (Exhibit 99.1).

Key Details

• Board approved the change on June 23, 2026; change disclosed in an 8-K filed June 24, 2026.
• New policy effective date: August 28, 2026.
• Policy requires the Fund to invest at least 80% of net assets (plus borrowings for investment purposes) in corporate debt obligations and/or income-producing investments.
• The policy language now permits including investments of non-corporate issuers within that 80% allocation.

Why It Matters This is a change to the Fund’s stated investment policy — not a report of performance or personnel change — and gives the fund manager clearer authority to include certain non-corporate income-producing securities within the 80% allocation. For investors, that could broaden the types of securities the Fund may hold and affect the Fund’s risk and yield profile over time. Investors should review the prospectus supplement and statement of additional information (Exhibit 99.1) for details on the scope and examples of permitted investments.
