Structured Note Terms and Payoff Mechanics for MSFL Preliminary Pricing Supplement No. 19,686

According to the filing, the securities are issued by Morgan Stanley Finance LLC (MSFL), a finance subsidiary of Morgan Stanley, under Registration Statement Nos. 333-293641 and 333-293641-01. The filing states that "as a finance subsidiary, MSFL has no independent operations and will have no independent assets." All payments on the securities are subject to Morgan Stanley's credit risk as guarantor.

The filing describes three hypothetical payoff scenarios at maturity. In an upside scenario, if the worst performing underlier appreciates 5%, investors would receive $1,069.50 per security, or 106.95% of the stated principal amount. In an absolute return participation scenario, if the worst performing underlier depreciates 5% (within the 20% buffer), investors would receive $1,050 per security, or 105% of the stated principal amount. In a downside scenario, if the worst performing underlier depreciates 95%, investors would lose 75% of their principal and receive only $250 per security, or 25% of the stated principal amount. At a hypothetical 0% change, the payment at maturity is $1,000 per security; at negative 20%, it is $1,200; at negative 21%, it falls to $990, illustrating the buffer boundary.

The filing discloses several risk factors. The estimated value of $924.00 per security is less than the $1,000 original issue price, which the filing attributes to "costs associated with issuing, selling, structuring and hedging the securities." The filing further notes that "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." The securities do not pay interest, and any positive return based on underlier depreciation is described as "effectively capped." Secondary market trading may be limited, and the U.S. federal income tax consequences are characterized as uncertain.
