Fully and Unconditionally Guaranteed by JPMorgan Chase & Co.

Notwithstanding anything to the contrary set forth in the preliminary pricing supplement dated August 29, 2019 related to the notes referred to above with the CUSIP and ISIN referred to below (the “preliminary pricing supplement”), the trade date for the notes is set forth below:

Trade date: on or about September 5, 2019

In addition, the second paragraph under “Summary Information — Key Terms — Supplemental Plan of Distribution” is deemed to be replaced in its entirety by the following paragraph:

“We expect to deliver the notes against payment therefor in New York, New York on or about September 11, 2019, which is the fourth scheduled business day following the date of this pricing supplement and of the pricing of the notes. Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on any date prior to two business days before delivery will be required, by virtue of the fact that the notes are initially expected to settle in four business days (T + 4), to specify alternative settlement arrangements to prevent a failed settlement.”

Furthermore, the second sentence under “Summary Information — Secondary Market Prices of the Notes” in the preliminary pricing supplement is deemed to be replaced in its entirety by the following sentence:

“In addition, we generally expect that some of the costs included in the original issue price of the notes will be partially paid back to you in connection with any repurchases of your notes by JPMS in an amount that will decline to zero over the period from the trade date through December 5, 2019.”

CUSIP no.: 48132FEX0

ISIN no.: US48132FEX06
