| &nbsp;&nbsp; **Summary Terms** | &nbsp;&nbsp; **Summary Terms** |
| &nbsp;&nbsp; **Issuer:** | &nbsp;&nbsp;&nbsp; Morgan Stanley Finance LLC |
| &nbsp;&nbsp; **Guarantor:** | &nbsp;&nbsp;&nbsp; Morgan Stanley |
| &nbsp;&nbsp; **Underlying stock:** | &nbsp;&nbsp;&nbsp; Vertiv Holdings Co class A common stock ("VRT") |
| &nbsp;&nbsp; **Stated principal amount:** | &nbsp;&nbsp;&nbsp; $1,000 per security |
| &nbsp;&nbsp; **Issue price:** | &nbsp;&nbsp;&nbsp; $1,000 per security |
| &nbsp;&nbsp; **Pricing date:** | &nbsp;&nbsp;&nbsp; August 1, 2025 |
| &nbsp;&nbsp; **Original issue date:** | &nbsp;&nbsp;&nbsp; August 6, 2025 (3 business days after the pricing date) |
| &nbsp;&nbsp; **Maturity date:** | &nbsp;&nbsp;&nbsp; August 4, 2028 |
| &nbsp;&nbsp; **Early redemption:** | &nbsp;&nbsp;&nbsp; If, on any of the first eleven determination dates, the determination closing price of the underlying stock is <u>greater than or equal t</u>o the initial share price, the securities will be automatically redeemed for an early redemption payment on the third business day following the related determination date, as set forth below. No further payments will be made on the securities once they have been redeemed. |
| &nbsp;&nbsp; **Early redemption payment:** | &nbsp;&nbsp;&nbsp; The early redemption payment will be an amount equal to (i) the stated principal amount *plus* (ii) the contingent quarterly coupon with respect to the related determination date and any previously unpaid contingent quarterly coupons from prior determination dates. |
| &nbsp;&nbsp; **Determination closing price:** | &nbsp;&nbsp;&nbsp; The closing price of the underlying stock on any determination date other than the final determination date *multiplied by* the adjustment factor on such determination date. |
| &nbsp;&nbsp; **Contingent quarterly coupon:** | &nbsp;&nbsp;&nbsp; ●If, on any determination date, the determination closing price or the final share **price**, as applicable, is greater than or equal to the downside threshold price, we will pay a contingent quarterly coupon at an annual rate of 12.75% (corresponding to approximately $31.875 per quarter per security) on the related contingent payment date.<br> ●If, on any determination date, the determination closing price or the final share price, as applicable, is less than the downside threshold price, no contingent quarterly coupon will be paid with respect to that determination date.<br> **If the contingent quarterly coupon is not paid on any contingent payment date (because the closing price on any determination date is less than the downside threshold price), such unpaid contingent quarterly coupon will be paid on a later contingent payment date but only if the determination closing price on such later determination date is greater than or equal to the downside threshold price; provided, however, in the case of any such payment of a previously unpaid contingent quarterly coupon, that no additional interest shall accrue or be payable in respect of such unpaid contingent quarterly coupon from and after the end of the original interest period for such unpaid contingent quarterly coupon. You will not receive such unpaid contingent quarterly coupons if the closing price is less than the downside threshold price on each subsequent determination date. If the closing price is less than the downside threshold price on each determination date, you will not receive any contingent quarterly coupons for the entire term of the securities.** |
| &nbsp;&nbsp; **Determination dates:** | &nbsp;&nbsp;&nbsp; Quarterly, beginning on November 3, 2025, as set forth below, subject to postponement for non-trading days and certain market disruption events. We also refer to August 1, 2028 as the final determination date. |
| &nbsp;&nbsp; **Contingent payment dates:** | &nbsp;&nbsp;&nbsp; With respect to each determination date other than the final determination date, the third business day after the related determination date, as set forth below. The payment of the contingent quarterly coupon, if any, with respect to the final determination date will be made on the maturity date. |

**Underlying Stock**

For more information about the underlying stock, including historical performance information, see the accompanying preliminary pricing supplement.

**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.

<u>Risks Relating to an Investment in the Securities</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●The securities do not guarantee the return of any principal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●The securities do not provide for the regular payment of interest.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●You will not receive any contingent quarterly coupon for any quarterly period where the determination closing price is less than the downside threshold price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●The contingent quarterly coupon, if any, is based solely on the determination closing price or the final share price, as applicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Investors will not participate in any appreciation in the price of the underlying stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●The automatic early redemption feature may limit the term of your investment to approximately three months. If the securities are redeemed early, you may not be able to reinvest at comparable terms or returns.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●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.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Investing in the securities is not equivalent to investing in the class A common stock of Vertiv Holdings Co.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●The securities will not be listed on any securities exchange and secondary trading may be limited.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●The estimated value of the securities is approximately $953.90 per security, or within $45.00 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.

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●The U.S. federal income tax consequences of an investment in the securities are uncertain.

<u>Risks Relating to the Underlying</u> <u>Stock</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●No affiliation with Vertiv Holdings Co.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●We may engage in business with or involving Vertiv Holdings Co without regard to your interests.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●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–Tax considerations" concerning the U.S. federal income tax consequences of an investment in the securities, and you should consult your tax adviser.
