Insights

Debt Capital Markets Analyst

Issuer priced fixed‑rate callable debt with model‑based call.

The offering is a plain fixed‑rate, issuer‑callable note due June 28, 2030 carrying a 4.500% coupon and standard semi‑annual payments. The call is governed by a risk neutral valuation model that uses market inputs and the issuer’s credit spreads from the pricing date.

The principal investor considerations are early redemption risk driven by the model, the notes’ exposure to Morgan Stanley’s creditworthiness and limited secondary market liquidity because the notes will not be listed. Subsequent filings will provide final aggregate size and final estimated value.

Structured‑Products Structurer

Pricing embeds issuance costs; estimated model value below issue price.

The pricing supplement states an estimated value of $982.20 per note on the pricing date, reflecting that the $1,000 issue price includes issuing, distribution and hedging costs borne by investors. That gap is consistent with structured note economics.

Key operational dependencies are the calculation agent’s discretionary determinations and the issuer’s hedging activity, which the supplement discloses may affect secondary pricing. Review the final pricing supplement for aggregate amount and exact commissions.

Fixed Rate Callable Notes

The Notes

The notes are debt securities of Morgan Stanley Finance LLC and are fully and unconditionally guaranteed by Morgan Stanley.

An early redemption, in whole but not in part, will occur on a redemption date if and only if the output of a risk neutral valuation model on a business day that is at least five but no more than eight business days prior to such redemption date, based on the inputs indicated in the call feature terms, indicates that redeeming on such date is economically rational for us as compared to not redeeming on such date. Any redemption payment will be at a redemption price equal to 100% of the principal amount to be redeemed, plus accrued and unpaid interest thereon to but excluding the redemption date. If we call the notes, we will give you notice at least five business days before the call date specified in the notice. On or before the redemption date, we will deposit with the trustee money sufficient to pay the redemption price of and accrued interest on the notes to be redeemed on that date. If such money is so deposited, on and after the redemption date, interest will cease to accrue on the notes (unless we default in the payment of the redemption price and accrued interest) and such notes will cease to be outstanding. We describe the basic features of these notes in the sections of the accompanying prospectus called “Description of Debt Securities—Fixed Rate Debt Securities” and prospectus supplement called “Description of Notes,” subject to and as modified by the provisions described below. For information regarding notices of redemption, see “Description of Debt Securities—Redemption and Repurchase of Debt Securities—Notice of Redemption” in the accompanying prospectus. All payments on the notes are subject to our credit risk.

The stated principal amount and issue price of each note is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the notes, which are borne by you, and, consequently, the estimated value of the notes on the pricing date will be less than the issue price. We estimate that the value of each note on the pricing date will be approximately $982.20 or within $52.20 of that estimate. Our estimate of the value of the notes as determined on the pricing date will be set forth in the final pricing supplement.

What goes into the estimated value on the pricing date?

In valuing the notes on the pricing date, we take into account that the notes comprise both a debt component and a performance-based component linked to interest rates. The estimated value of the notes is determined using our own pricing and valuation models, market inputs and assumptions relating to volatility and other factors including current and expected interest rates, as well as an interest rate related to our secondary market credit spread, which is the implied interest rate at which our conventional fixed rate debt trades in the secondary market.

What determines the economic terms of the notes?

In determining the economic terms of the notes, including the interest rate applicable to each interest payment period, we use an internal funding rate, which is likely to be lower than our secondary market credit spreads and therefore advantageous to us. If the issuing, selling, structuring and hedging costs borne by you were lower or if the internal funding rate were higher, one or more of the economic terms of the securities would be more favorable to you.

What is the relationship between the estimated value on the pricing date and the secondary market price of the notes?

The price at which MS & Co. purchases the notes in the secondary market, absent changes in market conditions, including those related to interest rates, may vary from, and be lower than, the estimated value on the pricing date, because the secondary market price takes into account our secondary market credit spread as well as the bid-offer spread that MS & Co. would charge in a secondary market transaction of this type, the costs of unwinding the related hedging transactions and other factors.

MS & Co. may, but is not obligated to, make a market in the notes and, if it once chooses to make a market, may cease doing so at any time.

Risk Factors

The notes involve risks not associated with an investment in ordinary fixed rate notes. This section describes the material risks relating to the notes. For a complete list of risk factors, please see the accompanying prospectus supplement, tax supplement and prospectus. Investors should consult their financial and legal advisers as to the risks entailed by an investment in the notes and the suitability of the notes in light of their particular circumstances.

Risks Relating to an Investment in the Notes

￭The notes have early redemption risk. Any early redemption, in whole but not in part, will occur on a redemption date if and only if the output of a risk neutral valuation model on a business day that is at least five but no more than eight business days prior to such redemption date, based on the inputs indicated in the call feature terms, indicates that redeeming on such date is economically rational for us as compared to not redeeming on such date. In accordance with the risk neutral valuation model determination noted herein, it is more likely that the issuer will redeem the notes prior to their stated maturity date to the extent that the interest payable on the notes is greater than the interest that would be payable on other instruments of the issuer of a comparable maturity, of comparable terms and of a comparable credit rating trading in the market. If the notes are redeemed prior to their stated maturity date, you will receive no further interest payments on the redeemed notes and may have to re-invest the proceeds in a lower interest rate environment.

￭Investors 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 notes. Investors are dependent on our ability to pay all amounts due on the notes on interest payment dates, on any redemption date and at maturity and therefore investors are subject to our credit risk and to changes in the market’s view of our creditworthiness. If we default on our obligations under the notes, your investment would be at risk and you could lose some or all of your investment. As a result, the market value of the notes prior to maturity will be affected by changes in the market’s view of our creditworthiness. Any actual or anticipated decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the value of the notes.

￭As a finance subsidiary, MSFL has no independent operations and will have no independent assets. As a finance subsidiary, MSFL has no independent operations beyond the issuance and administration of its securities and will have no independent assets available for distributions to holders of MSFL securities if they make claims in respect of such securities in a bankruptcy, resolution or similar proceeding. Accordingly, any recoveries by such holders will be limited to those available under the related guarantee by Morgan Stanley and that guarantee will rank pari passu with all other unsecured, unsubordinated obligations of Morgan Stanley. Holders will have recourse only to a single claim against Morgan Stanley and its assets under the guarantee. Holders of securities issued by MSFL should accordingly assume that in any such proceedings they would not have any priority over and should be treated pari passu with the claims of other unsecured, unsubordinated creditors of Morgan Stanley, including holders of Morgan Stanley-issued securities.

￭The price at which the notes may be sold prior to maturity will depend on a number of factors and may be substantially less than the amount for which they were originally purchased. Some of these factors include, but are not limited to: (i) actual or anticipated changes in interest and yield rates, (ii) any actual or anticipated changes in our credit ratings or credit spreads and (iii) time remaining to maturity. Generally, the longer the time remaining to maturity and the more tailored the exposure, the more the market price of the notes will be affected by the other factors described in the preceding sentence. This can lead to significant adverse changes in the market price of securities like the notes. Depending on the actual or anticipated level of interest and yield rates, the market value of the notes is expected to decrease and you may receive substantially less than 100% of the issue price if you are able to sell your notes prior to maturity.

￭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 notes in the original issue price reduce the economic terms of the notes, cause the estimated value of the notes to be less than the original issue price and will adversely affect secondary market prices. Assuming no change in market conditions or any other relevant factors, the prices, if any, at which dealers, including MS & Co., are willing to purchase the notes in secondary market transactions will likely be significantly lower than the original issue price, because secondary market prices will exclude the issuing, selling, structuring and hedging-related costs that are included in the original issue price and borne by you and because the secondary market prices will reflect our secondary market credit spreads and the bid-offer spread that

any dealer would charge in a secondary market transaction of this type, the costs of unwinding the related hedging transactions as well as other factors.

The inclusion of the costs of issuing, selling, structuring and hedging the notes in the original issue price and the lower rate we are willing to pay as issuer make the economic terms of the notes less favorable to you than they otherwise would be.

￭The estimated value of the notes 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. These pricing and valuation models are proprietary and rely in part on subjective views of certain market inputs and certain assumptions about future events, which may prove to be incorrect. As a result, because there is no market-standard way to value these types of securities, our models may yield a higher estimated value of the notes than those generated by others, including other dealers in the market, if they attempted to value the notes. In addition, the estimated value on the pricing date does not represent a minimum or maximum price at which dealers, including MS & Co., would be willing to purchase your notes in the secondary market (if any exists) at any time. The value of your notes at any time after the date of this pricing supplement will vary based on many factors that cannot be predicted with accuracy, including our creditworthiness and changes in market conditions.

￭The notes will not be listed on any securities exchange and secondary trading may be limited. The notes will not be listed on any securities exchange.  Therefore, there may be little or no secondary market for the notes. MS & Co. may, but is not obligated to, make a market in the notes and, if it once chooses to make a market, may cease doing so at any time. When it does make a market, it will generally do so for transactions of routine secondary market size at prices based on its estimate of the current value of the notes, taking into account its bid/offer spread, our credit spreads, market volatility, the notional size of the proposed sale, the cost of unwinding any related hedging positions, the time remaining to maturity and the likelihood that it will be able to resell the notes. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily. Since other broker-dealers may not participate significantly in the secondary market for the notes, the price at which you may be able to trade your notes is likely to depend on the price, if any, at which MS & Co. is willing to transact. If, at any time, MS & Co. were to cease making a market in the notes, it is likely that there would be no secondary market for the notes. Moreover, in accordance with the risk neutral valuation model determination noted herein, it is less likely that the issuer will redeem the notes prior to their stated maturity date to the extent that the interest payable on the notes is less than the interest that would be payable on other instruments of the issuer of a comparable maturity trading in the market. Accordingly, you should be willing to hold your notes to maturity.

￭Morgan Stanley & Co. LLC, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, has determined the estimated value on the pricing date. MS & Co. has determined the estimated value of the notes on the pricing date.

￭Our affiliates may publish research that could affect the market value of the notes. They also expect to hedge the issuer’s obligations under the notes. One or more of our affiliates may, at present or in the future, publish research reports with respect to movements in interest rates generally. This research is modified from time to time without notice to you and may express opinions or provide recommendations that are inconsistent with purchasing or holding the notes. Any of these activities may affect the market value of the notes. In addition, our affiliates expect to hedge the issuer’s obligations under the notes and they may realize a profit from that expected hedging activity even if investors do not receive a favorable investment return under the terms of the notes or in any secondary market transaction.

￭The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the notes. Any of these determinations made by the calculation agent may adversely affect the payout to investors. Moreover, certain determinations made by the calculation agent may require it to exercise discretion and make subjective judgments. These potentially subjective determinations may adversely affect the payout to you on the notes. For further information regarding these types of determinations, see “Description of Debt Securities—Fixed Rate Debt Securities” and related definitions in the accompanying prospectus.
