PIMCO STRATEGIC INCOME FUND, INC. 8-K

What Happened

• On June 24, 2026, PIMCO Strategic Income Fund, Inc. (ticker: RCS) filed an 8-K reporting an amendment to the Fund’s investment guidelines. Effective July 24, 2026, the Fund is permitted to invest without limitation in commercial mortgage‑related securities and may invest up to 50% of its total assets in debt instruments that are, at purchase, rated below investment grade (below Baa3 by Moody’s or below BBB‑ by S&P/Fitch) or unrated but deemed by PIMCO to be of comparable quality. The disclosure change will appear in the Fund’s shareholder reports beginning with the annual Form N‑CSR for the 12‑month period ended June 30, 2026.

Key Details

• Effective date: July 24, 2026 (8-K filed June 24, 2026).
• Commercial mortgage-related securities: permitted without any percentage limitation.
• Below-investment-grade exposure: up to 50% of total assets in debt rated below Baa3 (Moody’s) or below BBB‑ (S&P/Fitch), or unrated but judged comparable by PIMCO.
• Disclosure update: will be reflected in the Fund’s annual shareholder report on Form N‑CSR for the period ended June 30, 2026.

Why It Matters

• The change gives the Fund broader flexibility to increase exposure to commercial mortgage‑related securities and lower‑rated (high‑yield) debt, which can affect yield, credit quality, liquidity, and volatility of the Fund’s portfolio.
• Investors should review the Fund’s upcoming shareholder report and prospectus updates to understand how PIMCO intends to use these expanded permissions and any potential impact on portfolio risk and distributions.
