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 any return of principal.

●The appreciation potential is fixed and limited.

●The market price of the securities may 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 amount payable on the securities is not linked to the value of the underlying stock at any time other than the valuation date.

●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 $941.60 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.

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

●Investing in the securities is not equivalent to investing in the class A common stock of Space Exploration Technologies Corp.

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

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

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

Risks Relating to the Underlying Stock

●The underlying stock has very limited trading history.

●No affiliation with Space Exploration Technologies Corp.

●We may engage in business with or involving Space Exploration Technologies Corp. without regard to your interests.

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

●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.
