Citigroup Global Markets Holdings Inc., guaranteed by Citigroup Inc., is offering unsecured autocallable securities linked to the worst performing of the EURO STOXX 50® Index and the Nasdaq-100 Index®. The notes have a stated principal amount of $1,000 per security, pay no interest, and do not guarantee principal repayment.

If not called, and the worst index finishes below the 90% autocall barrier but at or above an 85% final barrier, investors receive only their $1,000 principal.

If at maturity the worst index is below its final barrier, repayment is reduced 1-for-1 with the index loss, potentially to zero. Per security economics include a $1,000 issue price, up to $41.00 underwriting fee, minimum proceeds to the issuer of $959.00, and an estimated value of at least $902.50 based on internal models.

All payments are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., and the securities are expected to have limited liquidity.

Investors forgo upside beyond the capped return, all dividends on index stocks, and interim interest. The notes carry the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., will not be listed, may have little or no secondary market, and have an estimated value on the trade date that is less than the issue price due to fees, hedging costs, and internal funding assumptions.

At maturity, if the worst-performing index is at or above its initial value, holders receive $1,000 plus the greater of a digital return of at least $800 (≥80% of principal, set on the pricing date) or $1,000 times that index’s positive return. If the worst-performing index is below its initial value but at or above 70% of its initial value, holders receive $1,000 plus the absolute value of that index’s negative return, giving upside to moderate declines.

The issue price is $1,000 per security, including an underwriting fee of up to $33.50, for minimum issuer proceeds of $966.50 per security.

Non-U.S. holders generally are not subject to U.S. withholding tax under current law, and the notes are expected not to be subject to Section 871(m) dividend-equivalent withholding.

Citigroup Global Markets Holdings Inc., fully guaranteed by Citigroup Inc., is issuing autocallable securities linked to the Dow Jones Industrial Average™, Russell 2000® Index and S&P 500® Equal Weight Index, maturing July 20, 2033, with a stated principal of $1,000 per security and total proceeds of $2,800,000.

The worst-performing index on each valuation date drives results. If, on any valuation date before maturity, the worst-performing index is at or above 95% of its initial level (its autocall barrier), the note is automatically redeemed for $1,000 plus a fixed premium, starting at 10.90% in 2027 and rising to 76.30% on the final valuation date. If not called, at maturity: if the worst-performing index is at or above 95% of its initial level, investors receive $1,000 plus the final premium; if it is between 75% and 95%, investors receive only $1,000; if it is below 75%, repayment is $1,000 plus $1,000 times the index return, exposing investors to full downside of the worst performer.

The securities are unsecured, not FDIC insured, and the estimated value at pricing is $988.10 per $1,000, reflecting issuer funding and hedging costs. Premiums are capped, so returns may lag direct index investment, and the product is described as significantly riskier than conventional debt.

Citigroup Global Markets Holdings Inc., guaranteed by Citigroup Inc., is offering unsecured structured notes linked to GE Vernova Inc. common stock. Each security has a stated principal amount of $1,000, a pricing date of July 15, 2026, and matures on July 19, 2029, unless automatically redeemed earlier.

The notes pay a contingent coupon at 17.10% per annum, due monthly only if the GE Vernova closing value on the prior calculation day is at or above the coupon threshold of $633.168 (60% of the starting value of $1,055.28). Missed coupons may be paid later if the threshold is met, via a “memory” feature. From October 2026 to June 2029, if on any potential autocall date the underlying closes at or above the starting value, the notes are automatically redeemed at $1,000 plus the due and any unpaid coupons.

If not called, the maturity payment depends on the final closing value. Investors receive $1,000 if the final value is at or above the downside threshold (also $633.168). If it is below, repayment equals $1,000 times the performance factor (final value divided by starting value), exposing investors to 1-for-1 downside and possible total loss of principal with no final coupon. The public offering price is $1,000 per note; the underwriting discount is $23.25, and the issuer’s proceeds are $976.75 per note. The estimated value on the pricing date is $958.40 per security, below the public offering price, reflecting selling, structuring, and hedging costs and the issuer’s internal funding rate. Credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., limited liquidity, and uncertain U.S. tax treatment are emphasized risk factors.

The notes are automatically called at par plus coupon on specified potential autocall dates if the worst performing index is at or above its initial level. If not called, the maturity payment depends on the worst performer on the final valuation date: investors receive $1,000 if it is at or above its final barrier (also 80% of initial); otherwise they lose 1% of principal for each 1% decline, down to zero. Investors do not receive dividends or upside participation, face full downside to the worst index, limited liquidity, and are exposed to the unsecured credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc. The issue price is $1,000 per security versus an estimated value of $961.
