Pricing Term Sheet

1.100% Senior Notes due 2027

The issuer has filed a registration statement (including a prospectus and the accompanying prospectus supplement) with the SEC for the offering to which this communication relates. Before you invest, you should read the prospectus and the accompanying prospectus supplement in that registration statement and other documents the issuer has filed with the SEC for more complete information about the issuer and this offering. You may get these documents for free by visiting EDGAR on the SEC website at www.sec.gov. Alternatively, the issuer, any underwriter or any dealer participating in the offering will arrange to send you the prospectus and the accompanying prospectus supplement if you request it by calling BofA Securities, Inc. at 1-800-294-1322 (toll-free), Citigroup Global Markets Inc. at 1-800-831-9146 (toll-free), J.P. Morgan Securities LLC at 212-834-4533 (toll-free), SMBC Nikko Securities America, Inc. at 888-868-6856 (toll-free) and Wells Fargo Securities, LLC at 800-645-3751 (toll-free).

We expect that delivery of the notes will be made to investors on or about August 16, 2021, which will be the tenth business day following the date of this pricing term sheet (such settlement cycle being referred to as “T+10”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market 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 more than two business days prior to their date of delivery will be required, by virtue of the fact that the notes initially settle in T+10, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement and should consult their own advisors.
