M&G Credit Income Investment Trust plc: Portfolio Update

M&G Credit Income Investment Trust plc (the “Company”)

Portfolio Update

LEI: 549300E9W63X1E5A3N24

17 March 2026

In light of recent market volatility driven by the Iran conflict, the artificial-intelligence related sell‑off in software companies and adverse news around private credit in the US, the Company reaffirms its cautious positioning. We have maintained a defensive stance, prioritising credit quality over incremental yield.

The overall portfolio maintains a solid investment‑grade profile with only approximately 20% in high-yield credit. The private portion of the portfolio has no direct software exposure, and software‑related holdings across the remainder of the portfolio represent less than 2% of the portfolio. The portfolio continues to be invested principally in Europe and the UK with only a small exposure to the US. Recent events are expected to have had an immaterial impact upon the value of the Company’s portfolio.

The recent market volatility underscores the value of the Company’s approach. Consistent with the Company’s strategy, periods of heightened volatility are expected to provide opportunities to add risk selectively and to enhance portfolio yield.
