Original issue date:	August 5, 2026 (3 business days after the pricing date)
Maturity date:	August 3, 2028
Early redemption:	If, on the first determination date, the determination closing price of the underlying stock is greater than or equal to the initial share price, the securities will be automatically redeemed for the early redemption payment on the early redemption date.

Payment at maturity1:	If the securities have not previously been redeemed, you will receive at maturity a cash payment per security as follows: •If the final share price is greater than or equal to the initial share price: $1,000 + ($1,000 × share percent change × 150%) •If the final share price is less than the initial share price but is greater than or equal to the downside threshold level: $1,000 + ($1,000 × absolute share return) In this scenario, you will receive a 1% positive return on the securities for each 1% negative return on the underlying stock. In no event will this amount exceed the stated principal amount plus $500. •If the final share price is less than the downside threshold level: $1,000 × share performance factor Under these circumstances, you will lose a significant portion, and possibly all, of your investment.
Absolute share return:	The absolute value of the share percent change. For example, a -5.00% share percent change will result in a +5.00% absolute share return.

Risk Considerations

The risks set forth below are discussed in more detail in the “Risk Factors” section in the accompanying preliminary pricing supplement. Please review those risk factors carefully prior to making an investment decision.

Risks Relating to an Investment in the Securities

●The securities do not pay interest or guarantee the return of any principal.

●If the securities are redeemed prior to maturity, the appreciation potential of the securities is limited by the fixed early redemption payment specified for the first determination date.

●The market price will be influenced by many unpredictable factors.

●The securities are subject to our credit risk, and any actual or anticipated changes to our credit ratings or credit spreads may adversely affect the market value of the securities.

●As a finance subsidiary, MSFL has no independent operations and will have no independent assets.

●Investing in the securities is not equivalent to investing in the underlying stock.

●Reinvestment risk.

●The securities will not be listed on any securities exchange and secondary trading may be limited, and accordingly, you should be willing to hold your securities for the entire 2-year term of the securities.

●The rate we are willing to pay for securities of this type, maturity and issuance size is likely to be lower than the rate implied by our secondary market credit spreads and advantageous to us. Both the lower rate and the inclusion of costs associated with issuing, selling, structuring and hedging the securities in the original issue price reduce the economic terms of the securities, cause the estimated value of the securities to be less than the original issue price and will adversely affect secondary market prices.

●The estimated value of the securities is approximately $952.80 per security, or within $35.00 of that estimate, and is determined by reference to our pricing and valuation models, which may differ from those of other dealers, and is not a maximum or minimum secondary market price.

●Hedging and trading activity by our affiliates could potentially affect the value of the securities.

●The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the securities.

●The U.S. federal income tax consequences of an investment in the securities offered by the accompanying preliminary pricing supplement are uncertain.

Risks Relating to the Underlying Stock

●Governmental regulatory actions, such as sanctions, could adversely affect your investment in the securities.

●No affiliation with Micron Technology, Inc.

●We may engage in business with or involving Micron Technology, Inc. without regard to your interests.

●The antidilution adjustments the calculation agent is required to make do not cover every corporate event that could affect the underlying stock.

Tax Considerations

You should review carefully the discussion in the accompanying preliminary pricing supplement under the caption “Additional Information About the Securities–United States federal income tax considerations” concerning the U.S. federal income tax consequences of an investment in the securities, and you should consult your tax adviser.
