This document provides a summary of the terms of the securities offered by Morgan Stanley Finance LLC. Investors should review carefully the accompanying preliminary terms, product supplement, index supplement and prospectus prior to making an investment decision.
SUMMARY TERMS  
Issuer:  Morgan Stanley Finance LLC (“MSFL”)  
Guarantor:  Morgan Stanley  
Underlying indices:  Russell 2000^{®} Index (the “RTY Index”) and S&P 500^{® }Index (the “SPX Index”). For more information about the underlying indices, see the accompanying preliminary terms.  
Stated principal amount:  $1,000 per security  
Pricing date:  May 28, 2019  
Original issue date:  May 31, 2019 (3 business days after the pricing date)  
Maturity date:  December 3, 2020  
Early redemption:  The securities are not subject to automatic early redemption until six months after the original issue date. Following this initial 6month noncall period, if, on any of the four redemption determination dates, beginning on November 29, 2019, the index closing value of each underlying index is greater than or equal to its respective initial index value, the securities will be automatically redeemed for an early redemption payment on the related early redemption date. No further payments will be made on the securities once they have been redeemed. The securities will not be redeemed early on any early redemption date if the index closing value of either underlying index is below the respective initial index value for such underlying index on the related redemption determination date. 

Early redemption payment:  The early redemption payment will be an amount equal to (i) the stated principal amount for each security you hold plus (ii) the contingent monthly coupon with respect to the related observation date.  
Contingent monthly coupon:  A contingent coupon at an annual rate of 5.15% to 7.15% (corresponding to approximately $4.2917 to $5.9583 per month per security, to be determined on the pricing date) will be paid on the securities on each coupon payment date but only if the closing value of each underlying index is at or above its respective coupon barrier level on the related observation date. If, on any observation date, the closing value of either underlying index is less than the respective coupon barrier level for such underlying index, we will pay no coupon for the applicable monthly period. 

Trigger event:  A trigger event occurs if, on any index business day from but excluding the pricing date to and including the final observation date, the closing level of either underlying index is less than its respective downside threshold level.  
Payment at maturity:  At maturity, investors will receive, in addition to the final contingent monthly coupon payment, if payable, a payment at maturity determined as follows: If a trigger event HAS NOT occurred on any index business day during the term of the securities up to and including the final observation date: the stated principal amount If a trigger event HAS occurred on any index business day during the term of the securities up to and including the final observation date: (i) the stated principal amount multiplied by (ii) the index performance factor of the worst performing underlying index, subject to a maximum payment at maturity of the stated principal amount. 

Agent:  Morgan Stanley & Co. LLC, an affiliate of MSFL and a wholly owned subsidiary of Morgan Stanley. See “Supplemental information regarding plan of distribution; conflicts of interest” in the accompanying preliminary terms. The agent commissions will be as set forth in the final pricing supplement.  
Estimated value on the pricing date:  Approximately $964.00 per security, or within $15.00 of that estimate. See “Investment Summary” in the accompanying preliminary terms.  
Terms continued on the following page 
Overview
The securities offered are unsecured obligations of MSFL and are fully and unconditionally guaranteed by Morgan Stanley. The securities have the terms described in the accompanying preliminary terms, product supplement, index supplement and prospectus. The securities do not guarantee the repayment of principal and do not provide for the regular payment of interest. Instead, the securities will pay a contingent monthly coupon but only if the index closing value of each of the Russell 2000^{®} Index and the S&P 500^{® }Index is at or above its coupon barrier level of 70% of its respective initial index value on the related observation date. If, however, the index closing value of either underlying index is less than its coupon barrier level on any observation date, we will pay no interest for the related monthly period. In addition, the securities will be automatically redeemed if the index closing value of each underlying index is greater than or equal to its respective initial index value on any of the four quarterly redemption determination dates (beginning approximately six months after the original issue date) for the early redemption payment equal to the sum of the stated principal amount plus the related contingent monthly coupon. At maturity, if the securities have not previously been redeemed and the index closing value of each underlying index has remained greater than or equal to 70% of the respective initial index value, which we refer to as the downside threshold level, on each index business day during the term of the securities, the payment at maturity will be the stated principal amount and the related contingent monthly coupon. If, however, the index closing value of either underlying index is less than its respective downside threshold level on any index business day during the term of the securities, a trigger event will have occurred and investors will be fully exposed to the decline in the worst performing underlying index on a 1to1 basis and, if the final index value of either underlying index is less than its initial index value, investors will receive a payment at maturity that is less than the stated principal amount of the securities and could be zero. Accordingly, investors in the securities must be willing to accept the risk of losing their entire initial investment and also the risk of not receiving any contingent monthly coupons throughout the 1.5year term of the securities. Because all payments on the securities are based on the worst performing of the underlying indices, a decline beyond the respective coupon barrier level or respective downside threshold level, as applicable, of either underlying index will result in few or no contingent coupon payments and a potentially significant loss of your investment, even if the other underlying index has appreciated or has not declined as much. The securities are for investors who are willing to risk their principal and seek an opportunity to earn interest at a potentially abovemarket rate in exchange for the risk of receiving no monthly coupons over the entire 1.5year term. Investors will not participate in any appreciation of either underlying index. The securities are notes issued as part of MSFL’s Series A Global MediumTerm Notes program.
All payments are subject to our credit risk. If we default on our obligations, you could lose some or all of your investment. These securities are not secured obligations and you will not have any security interest in, or otherwise have any access to, any underlying reference asset or assets.
Investing in the securities involves risks. See “Selected Risks” on the following page and “Risk Factors” in the accompanying preliminary terms.

Risk Considerations
The risks set forth below are discussed in more detail in the “Risk Factors” section in the accompanying preliminary terms. Please review those risk factors carefully prior to making an investment decision.
·  The securities do not guarantee the return of any principal. 
·  The securities do not provide for the regular payment of interest. 
·  You are exposed to the price risk of both underlying indices, with respect to both the contingent monthly coupons, if any, and the payment at maturity, if any. 
·  Because the securities are linked to the performance of the worst performing underlying index, you are exposed to greater risks of receiving no contingent monthly coupons and sustaining a significant loss on your investment than if the securities were linked to just one index. 
·  The contingent monthly coupon, if any, is based on the value of each underlying index on only the related monthly observation date at the end of the related interest period. 
·  Investors will not participate in any appreciation in either underlying index. 
·  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. 
·  The securities are linked to the Russell 2000^{®} Index and are subject to risks associated with smallcapitalization companies. 
·  Not equivalent to investing in the underlying indices. 
·  Reinvestment risk. 
·  The securities will not be listed on any securities exchange and secondary trading may be limited. Accordingly, you should be willing to hold your securities for the entire 1.5year 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 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. 
·  Adjustments to the underlying indices could adversely affect the value of the securities. 
·  The U.S. federal income tax consequences of an investment in the securities are uncertain. 
Tax Considerations
You should review carefully the discussion in the accompanying preliminary terms under the caption “Additional Information About the Securities– Tax considerations” concerning the U.S. federal income tax consequences of an investment in the securities. However, you should consult your tax adviser regarding all aspects of the U.S. federal income tax consequences of an investment in the securities, as well as any tax consequences arising under the laws of any state, local or nonU.S. taxing jurisdiction.
Hypothetical Examples
The following hypothetical examples illustrate how to determine whether a contingent monthly coupon is paid with respect to an observation date and how to calculate the payment at maturity if the securities have not been automatically redeemed early. The following examples are for illustrative purposes only. Whether you receive a contingent monthly coupon will be determined by reference to the index closing value of each underlying index on each monthly observation date, and the amount you will receive at maturity, if any, will be determined by reference to the index closing value of each underlying index throughout the term of the securities. The actual initial index value, coupon barrier level and downside threshold level for each underlying index will be determined on the pricing date. All payments on the securities, if any, are subject to our credit risk. The numbers in the hypothetical examples below may have been rounded for the ease of analysis. The below examples are based on the following terms:
Hypothetical Contingent Monthly Coupon:  6.15% per annum (corresponding to approximately $5.125 per month per security, the midpoint of the range set forth on the cover of this document)* 
Stated Principal Amount:  $1,000 
Hypothetical Initial Index Value: 
With respect to the RTY Index: 1,200 With respect to the SPX Index: 2,500 
Hypothetical Coupon Barrier Level: 
With respect to the RTY Index: 840, which is 70% of the hypothetical initial index value for such index With respect to the SPX Index: 1,750, which is 70% of the hypothetical initial index value for such index 
Hypothetical Downside Threshold Level: 
With respect to the RTY Index: 840, which is 70% of the hypothetical initial index value for such index With respect to the SPX Index: 1,750, which is 70% of the hypothetical initial index value for such index 
* The actual contingent monthly coupon will be an amount determined by the calculation agent based on the actual contingent monthly coupon rate and the number of days in the applicable payment period, calculated on a 30/360 basis. The hypothetical contingent monthly coupon of $5.125 is used in these examples for ease of analysis.
How to determine whether a contingent monthly coupon is payable with respect to an observation date:
Closing Level  Contingent Monthly Coupon  
RTY Index  SPX Index  
Hypothetical Observation Date 1  950 (at or above coupon barrier level)  2,100 (at or above coupon barrier level)  $5.125 
Hypothetical Observation Date 2  600 (below coupon barrier level)  2,600 (at or above coupon barrier level)  $0 
Hypothetical Observation Date 3  1,200 (at or above coupon barrier level)  1,400 (below coupon barrier level)  $0 
Hypothetical Observation Date 4  500 (below coupon barrier level)  1,200 (below coupon barrier level)  $0 
On hypothetical observation date 1, both the RTY Index and SPX Index close at or above their respective coupon barrier levels. Therefore a contingent monthly coupon of $5.125 is paid on the relevant coupon payment date.
On each of the hypothetical observation dates 2 and 3, one underlying index closes at or above its coupon barrier level, but the other underlying index closes below its coupon barrier level. Therefore, no contingent monthly coupon is paid on the relevant coupon payment date.
On hypothetical observation date 4, each underlying index closes below its respective coupon barrier level, and, accordingly, no contingent monthly coupon is paid on the relevant coupon payment date.
You will not receive a contingent monthly coupon on any coupon payment date if the closing level of either underlying index is below its respective coupon barrier level on the related observation date.
How to calculate the payment at maturity (if the securities have not been automatically redeemed early):
Example 1: A trigger event HAS NOT occurred.
Final Index Value  RTY Index: 1,800  
SPX Index: 3,000  
Payment at Maturity  =  $1,000.00 + $5.125 (contingent monthly coupon for the final monthly period) 
=  $1,005.125 
In example 1, the index closing values of both the RTY Index and SPX Index are at or above their respective downside threshold levels on each index business day during the term of the securities. Therefore, a trigger event has not occurred and investors receive at maturity the stated principal amount of the securities and the contingent monthly coupon with respect to the final observation date. However, investors do not participate in any appreciation of either underlying index.
Example 2: A trigger event HAS occurred.
Final Index Value  RTY Index: 960  
SPX Index: 3,000  
Payment at Maturity  =  $5.125 (contingent monthly coupon for the final monthly period) + [$1,000 x index performance factor of the worst performing underlying index, subject to a maximum of the stated principal amount] 
=  $5.125 + [$1,000 x (960 / 1,200)]  
=  $805.125 
In example 2, the index closing value of one underlying index is at or above its downside threshold level on each index business day during the term of the securities, but the index closing value of the other underlying index is below its downside threshold level on one or more index business days during the term of the securities. The final index values of both the RTY Index and the SPX Index are at or above the respective coupon barrier levels on the final observation date. However, because a trigger event has occurred, investors are exposed to the downside performance of the worst performing underlying index at maturity, even though one of the underlying indices has appreciated. Because the final index value of each underlying index is greater than its respective coupon barrier level, investors receive the contingent monthly coupon with respect to the final observation date. The payment at maturity is an amount equal to the contingent monthly coupon with respect to the final observation date plus (i) the stated principal amount times (ii) the index performance factor of the worst performing underlying index.
Example 3: A trigger event HAS occurred.
Final Index Value  RTY Index: 600  
SPX Index: 1,000  
Payment at Maturity  =  $1,000 x index performance factor of the worst performing underlying index 
=  $1,000 x (1,000 / 2,500) = $400  
=  $400 
In example 3, the index closing values of both the RTY Index and SPX Index are below the respective downside threshold levels on one or more index business days during the term of the securities. Therefore, a trigger event has occurred, and investors are exposed to the downside performance of the worst performing underlying index at maturity. Because the final index value of one or both underlying indices are below the respective coupon barrier levels, investors do not receive the contingent monthly coupon with respect to the final observation date. The payment at maturity is an amount equal to the stated principal amount times the index performance factor of the worst performing underlying index.
If a trigger event occurs on any index business day during the term of the securities, investors will have full downside exposure to the worst performing underlying index at maturity. Under these circumstances, if the final index value of either underlying index is less than its respective initial index value, investors will lose some or all of their investment in the securities.
