Based on the Worst Performing of the S&P 500®Index, the Nasdaq-100® Technology Sector IndexSMand theRussell 2000®Index Fully and Unconditionally Guaranteed by Morgan StanleyPrincipal at Risk Securities The securities are unsecured obligations of Morgan Stanley Finance LLC (“MSFL”) and are fully and unconditionally guaranteed by MorganStanley. The securities have the terms described in the accompanying product supplement, index supplement, tax supplement andprospectus, as supplemented or modified by this document. The securities do not guarantee the repayment of principal and do not providefor the regular payment of interest. Automatic early redemption.The securities will be automatically redeemed if the closing level ofeachunderlier isgreater than or equaltoits call threshold level on any determination date (other than the final determination date) for an early redemption payment that willincrease over the term of the securities. No further payments will be made on the securities once they have been automatically redeemed. Payment at maturity.If the securities have not been automatically redeemed prior to maturity and the final level ofeachunderlier isgreater than or equal toits call threshold level, investors will receive a fixed positive return at maturity. If the final level ofanyunderlier isless thanits call threshold level but the final level ofeachunderlier isgreater than or equal toits downside threshold level, investors willreceive only the stated principal amount at maturity. If, however, the final level ofanyunderlier isless thanits downside threshold level,investors will lose 1% for every 1% decline in the level of the worst performing underlier over the term of the securities.Under thesecircumstances, the payment at maturity will be significantly less than the stated principal amount and could be zero. The value of the securities is based on the worst performing underlier.The fact that the securities are linked to more than oneunderlier does not provide any asset diversification benefits and instead means that a decline in the level of any underlier beyond itsdownside threshold level will adversely affect your return on the securities, even if the other underliers have appreciated or have notdeclined as much. The securities are for investors who are willing to risk their principal and forgo current income in exchange for the possibility of receiving anearly redemption payment or payment at maturity that exceeds the stated principal amount.
