At maturity, investors receive $1,000 plus 100% of any positive S&P 500® return, capped at a maximum return of 17.50%, for a maximum payment of $1,175 per note. If the index is flat, investors receive $1,000. If the index falls, investors have 1‑to‑1 downside exposure to the first 5% decline and may receive as little as $950 per note, a 5% loss of face amount.

The notes are senior unsecured obligations of Jefferies, fully subject to its credit risk, and will not be listed on any exchange. Jefferies estimates the value on the pricing date at $961 per $1,000 note, below the offering price, reflecting selling, structuring and hedging costs and its internal funding rate.

Jefferies Financial Group Inc. is offering senior unsecured medium-term notes linked to the S&P 500® Index, structured as auto-callable, buffered downside, principal-at-risk securities due January 4, 2030. Each security has a $1,000 face amount and pays no periodic interest.

If on any call date from January 2027 through December 31, 2029 the Index closing level is at or above the starting level of 6,905.74, the notes are automatically called for $1,000 plus a call premium of 8.00%, 16.00%, 24.00% or 32.00% of face, depending on the call year. Investors do not participate in any additional Index gains beyond these capped premiums.

If the notes are not called, maturity repayment depends on the Index on the final calculation day. Full principal is returned if the Index ending level is at least the threshold level of 6,387.8095 (92.50% of start). Below that, investors have 1‑to‑1 downside exposure beyond the 7.50% buffer, with losses up to 92.50% of principal. The issuer estimates the value on the pricing date at $971.00 per $1,000 security. The total offering is $1,813,000, with proceeds to the issuer of approximately $1,766,315.25 after agent discounts. The notes will not be listed, may have limited liquidity, are subject to Jefferies’ credit risk, and involve complex and uncertain U.S. tax treatment.
