The Dow Chemical Company InterNotes

If the maturity date or an interest payment date for any note is not a business day (as such term is defined in prospectus), principal and premium, if any, and interest for that note is paid on the next business day, and no further such interest will accrue from, and including, the maturity date or such interest payment date.

*It is expected that delivery of the notes will be made against payment therefor on or about August 14, 2025, which is the third business day following the trade date (such settlement cycle being referred to as “T+3”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in one business day unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on any date prior to the business day before delivery will be required, by virtue of the fact that the notes initially will settle in T+3, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of the notes who wish to trade the notes prior to the business day before delivery should consult their own advisors.

Capitalized terms used in this pricing supplement that are defined in the InterNotes prospectus supplement (the “Prospectus Supplement”) shall have the meanings assigned to them in the Prospectus Supplement unless otherwise defined herein.

Legal Matters:

In the opinion of Shandell S. Massey, Senior Managing Counsel and Director, Office of the Corporate Secretary, of The Dow Chemical Company (the “Company”), the notes offered by this pricing supplement have been duly authorized, and when executed and issued by the Company, authenticated by the Trustee pursuant to the Indenture, and delivered against payment as contemplated herein, such notes will be legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms and entitled to the benefits of the Indenture (subject to applicable bankruptcy, reorganization, insolvency, moratorium or other laws affecting creditors’ rights generally from time to time in effect and to general principles of equity). This opinion is given as of the date hereof and is limited to the law of the State of New York and the General Corporation Law of the State of Delaware as in effect on the date hereof. In addition, this opinion is subject to the same assumptions and qualifications stated in the letter of such counsel dated July 25, 2025, filed in the Company’s Current Report on Form 8-K dated July 25, 2025 and incorporated by reference as Exhibit 5.2 to the Company’s registration statement on Form S-3 ASR (File No. 333-288028-01).
