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 provide for only the minimum payment at maturity.

●Investors will not participate in any appreciation in the value of the underlier.

●The securities are subject to early redemption risk.

●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 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.

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

●As discussed in more detail in the accompanying product supplement, investing in the securities is not equivalent to investing in the underlier(s).

●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 Underlier(s)

●Because your return on the securities will depend upon the performance of the underlier(s), in addition to any risks described further below, the securities are subject to the following risk(s) discussed in more detail in the accompanying index supplement. The accompanying index supplement refers to the underlier as the “Index.”

oNo assurance can be given that the investment strategy used to construct the Index will achieve its intended results or that the Index will be successful or will outperform any alternative index or strategy that might reference the Index Components.

oThe decrement of 4% per annum will adversely affect the performance of the Index in all cases, whether the Index appreciates or depreciates.

oThe Index is subject to risks associated with the use of significant leverage.

oThe Index may not be fully invested.

oThe Index was established on March 14, 2022 and therefore has very limited operating history.

oAs the Index is new and has very limited historical performance, any investment in the Index may involve greater risk than an investment in an index with longer actual historical performance and a proven track record.

oHigher future prices of the futures contract to which the Index is linked relative to its current prices may adversely affect the value of the Index and the value of instruments linked to the Index.

oSuspensions or disruptions of market trading in futures markets could adversely affect the price of instruments linked to the Index.

oLegal and regulatory changes could adversely affect the return on and value of your securities.

oThe E-mini Russell 2000 futures contracts are one of the Index Components and are subject to risks associated with small-capitalization companies.

oAdjustments to the Index could adversely affect the value of instruments linked to the Index.

Risks Relating to Conflicts of Interest

●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.

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.
