#### Item 8.01 Other Events.
On September 17, 2025, the Board of Trustees (the "Board") of the PIMCO California Municipal Income Fund (the "Fund") approved a change to the Fund's non-fundamental investment guidelines to reduce the Fund's minimum investment guideline for California Municipal Bonds (as defined below) from 90% to 80%. Accordingly, effective as of October 20, 2025, the Fund will invest, under normal circumstances, at least 80% of its net assets in municipal bonds which pay interest that, in the opinion of bond counsel to the issuer (or on the basis of other authority believed by PIMCO to be reliable), is exempt from California income taxes (i.e., excluded from gross income for California income tax purposes) ("California Municipal Bonds"). The Fund will continue to invest in accordance with its fundamental policy to, under normal circumstances, invest at least 80% of its "assets" (as that term is defined in Rule 35d-1 under the Investment Company Act of 1940, as amended), measured at the time of investment, in investments the income from which is, in the opinion of bond counsel to the issuer (or on the basis of other authority believed by the Fund's portfolio manager to be reliable), exempt from federal and California state income taxes.

The change will be reflected in the Fund's shareholder reports beginning with the Fund's annual shareholder report on Form N-CSR for the 12-month reporting period ended December 31, 2025.
