Citigroup Global Markets Holdings Inc. Prices $1,000 Autocallable Contingent Coupon Notes Linked to Worst-Performing of Nasdaq-100, Russell 2000, and S&P 500

Citigroup Global Markets Holdings Inc. is issuing autocallable contingent coupon notes with $1,000 stated principal, due October 29, 2029, linked to the worst performing of three equity indices

Contingent coupon of 1.7125% per payment (6.85% annualized) is paid only if worst performing underlying is at or above 70% of its initial value on the applicable valuation date

Securities may be automatically called for redemption at $1,000 plus contingent coupon if worst performing underlying equals or exceeds its initial underlying value on any potential autocall date

At maturity, if worst performing underlying is below 60% of its initial value, investors receive less than principal based on the underlying's negative return, with potential total loss of investment

Initial underlying values set on strike date October 21, 2026: Nasdaq-100 Index at 29,822.52, Russell 2000 Index at 2,781.021, and S&P 500 Index at 7,757.17

Underwriting fee is $30.00 per security with estimated value of at least $908.00 on pricing date, less than the $1,000 issue price

Securities will not be listed on any securities exchange and have limited secondary market liquidity
